Description

Power station for strength training of a user

The present invention relates to a power station for a user to perform strength exercises, also known as a multi-function exercise machine. In such multi-purpose exercise equipment (i.e., power stations), the resistance required for the user's strength exercises is typically transmitted to the user of the power station through one or more tension ropes or cables. The resistance is typically variable over a wide range so that a user at a power station exercises different muscle groups for different types of users (e.g., female-male or advanced-beginner).

A similar type of power station is described in publication DE 20 2021 101 365 U1. The exercise machine includes a resistance device for generating a resistance or exercise force. Such resistance means have a rotating arm and a force generating means cooperating with the rotating arm. The rotary arm and the force generating device are connected to each other by an adjusting unit for changing the point of application of the force generating device on the rotary arm. Such a structural design allows fine stepwise or even stepless adjustment of the resistance or training force over a large area and saves a lot of material, such as cast iron or steel for the weights used in conventional power stations.

Typically, the resistance in the force station is regulated by a plurality of counterweights, as shown for example in publication DE 20 2011 004 686U1. A major drawback of such solutions is that a large amount of material, such as cast iron or steel, is required in the manufacture of the balancing weight in order to be able to generate sufficient resistance. In addition, the resistance of such power stations is often adjusted in steps, for example, with one gear per 2.5 kg or 5 kg, and thus is difficult to fine tune for certain muscle groups or specific requirements of a particular user.

To solve the above-mentioned balancing weights and fine tuning problems, one or more electric drives may be used in the power station, as shown for example in publication WO 2014/175839 A1. However, such solutions are costly and technically complex.

In addition, the power station is typically provided with a platform upon which a user can stand for strength exercises using elastic tension cords secured to the platform, while the user's own weight can be used to stabilize the platform. Such conventional elastic tension ropes have a disadvantage in that the elasticity is lost or the resistance characteristics of the tension ropes are changed with the lapse of time. In addition, in order to change the force load required for training, the user must also replace the elastic tension ropes fixed to the platform. The object of the present invention is to provide a power station for a user to exercise strength that can be produced in a cost-effective, material-saving and space-saving manner and that generates resistance in a simple and effective manner, preferably in small gear adjustments or even in a stepless manner, so that the resistance properties of the tensile cord do not change adversely over time. Furthermore, the power station according to the invention can be space-saving, for example can be stored under a user's bed.

The present invention accomplishes the above task by the features of the independent claims. Further advantageous developments are the subject matter of the dependent claims.

In summary, the applicant of the present invention has first appreciated that the above-mentioned problems can be solved in a simple and economical manner by means of a resistance device he developed for generating resistance or training forces. Such resistance means preferably have a rotating arm and a force generating means cooperating with the rotating arm. The swivel arm and the force generating means are suitably interconnected by an adjustment unit, which preferably serves to change the point of application of the force generating means on the swivel arm. Such a structural design allows fine stepwise or even stepless adjustment of the resistance or training force over a large area and saves a lot of material, such as cast iron or steel for the weights used in conventional power stations.

In this case, the force-generating device is preferably designed as a hydraulic or pneumatic device, in particular as a hydraulic or pneumatic cylinder. However, the force-generating device may also be a combination of hydraulic or pneumatic devices, in particular a hydraulic cylinder or a pneumatic cylinder, for example equipped with additional mechanical and/or electrical components (e.g. springs, hydraulic or pneumatic actuators, etc.).

Such power stations are commonly used in gymnasiums. As a first example, the same type of power station sold by the applicant is equipped with two symmetrically positioned resistance devices or two swivel arms, such as shown in FIG. 1. However, such power stations require a large amount of space or require a large space requirement in terms of width to be properly used by the user. The power station 1 in fig. 1 comes from the document DE 20 2021 101 365 U1.

As shown in fig. 1, the power station 1 has a frame assembly 2 that includes a base 3, a longitudinal support 4, and a seat or seating area 19. In a preferred embodiment, the seating area 19 of the power station 1 can be designed to be tiltable. Preferably, the seating area 19 can be tilted stepwise or continuously in the range of 0 ° to 90 °, e.g. tilting the seating area 19 of the power station 1 by about 45 ° can be used as a resting surface and support surface for the back of the user in order to perform back exercises. Thus, the seating area 19 is hereinafter referred to as a support means 19. Furthermore, it can be seen from fig. 1 that the power station 1 has two resistance devices 6, 11, 16 for generating resistance. Each resistance device is provided with a rotating arm 6, a force-generating device 11 which is matched with the rotating arm 6 and an adjusting unit 16 for changing the application point of the force-generating device 11 on the corresponding rotating arm 6.

In this case, the width W of the power station 1 shown in fig. 1 in the so-called initial state is determined by the distance between the outermost free ends of the swivel arm 6, i.e. the horizontal distance between the two ends 10 of the swivel arm 6, since the ends 10 are the two parts of the power station 1 that are furthest apart in width. The initial state of the power station 1 is shown in fig. 1 by a solid line, while the so-called operating state of the power station 1 is shown in fig. 1 by a dashed line. In the above, the "initial state" is understood as a state in which the power station is not used, i.e. in a stationary state, without a user interacting with the power station or training with the power station.

On the other hand, "running" or "running state" refers to a state in which the user actively uses the force station, for example, the user moves the swivel arm or the user uses or pulls the tension cord.

As can be seen from comparing the two states, in the initial state, the width W of the power station 1 of the present embodiment is larger. However, other embodiments are also conceivable in which the width W of the power station 1 in the initial state is smaller than the width W in the operating state.

Recently, especially in epidemic situations, power stations are installed not only in gyms, but also increasingly in the private residences of users. The applicant has thus appreciated that the area or design of the user's private residence often makes it impossible for them to install a power station with swivel arms in the home. Although such sites are often provided with a number of compartments or cells which are in principle suitable for housing the power station, these compartments or cells are often too narrow to accommodate the power station with swivel arms.

Fig. 2A-2C show several views of another similar power station 1 developed by the same applicant in the document DE 20 2021 101 365 U1. More specifically, figs. 2A-2C illustrate a compact space-saving power station 1 for a user to perform a strength exercise.

The power station 1 has a frame means 2 comprising a base 3, a longitudinal support 4 and support means 19 or seating area 19, wherein the base 3 is used for placing the power station 1 on the floor of a room and the support means 19 are used for supporting the exercise position of the user during the power exercise.

The longitudinal support 4 is arranged on the base 3 and the support means 19 are arranged on the longitudinal support 4 and the base 3, so that a stable placement of the power station 1 on the floor is ensured during the strength exercise.

Figures 2A-2C also show that the power station 1 has a resistance means 6, 11, 16 for generating resistance. Each resistance device is provided with a rotating arm 6, a force-generating device 11 which is matched with the rotating arm 6 and an adjusting unit 16 for changing the application point of the force-generating device 11 on the rotating arm 6. In this case, the resistance means 6, 11, 16 have only one swivel arm 6, so that the power station 1 in fig. 2 can be designed more space-saving than in fig. 1.

The adjusting unit 16 is adjustably connected to the swivel arm 6 to adjust the resistance required for the user's strength exercise step by step or steplessly. Thus, according to the lever principle, the force of the force-generating device 11 on the swivel arm 6 can be adjusted by the adjusting unit 16.

In addition, fig. 2A-2C also show that the positioning of the swivel arm 6 on the power station 1 is selected in such a way that the width W of the power station 1 is minimized. Referring particularly to fig. 2A-2C, the width W of the power station 1 is minimal in the initial state.

An "initial state" or "in an initial state" is understood to be a state in which the force station is not in use, i.e. in a stationary state, with no user interaction with the force station or training with the force station.

On the other hand, "operating state" or "in operating state" refers to a state in which the user actively uses the force station 1, for example, the user's action moves the swivel arm 6, or the user uses or pulls the tension string.

As is evident from reference to fig. 2A-2C, the width W in the initial state shown in the above figures is greater than the width W in the operating state. This is because in the operating state the user interaction with the power station 1 causes the swivel arm 6 to swivel about the first end 9 of the swivel arm 6.

For the sake of clarity and understanding, the term "width" refers to the horizontal distance between the outermost ends of the rotary arms 6 of the resistance devices 6, 11, 16 in the initial state.

It is this horizontal distance or width W of the power station 1 that is reduced to a minimum by means of the positioning of the swivel arm 6 on the power station 1, especially in the initial state of the power station 1.

Furthermore, fig. 2A-2C show that the resistance means 6, 11, 16, in particular the swivel arm 6 thereof, are essentially in a central position with respect to the position of the user on the power station 1 or with respect to the position of the support means 19 during the strength exercise.

In other words, the resistance means 6, 11, 16, in particular the swivel arm 6 thereof, are connected to the transverse strut 5 connected to the longitudinal strut 4, so that the resistance means 6, 11, 16, in particular the swivel arm 6 thereof, is substantially in the central position of the back of the user when the user is resting on the longitudinal strut 4 on the support means 19.

Referring to fig. 2A-2C, the frame device 2 has a transverse strut 5 arranged on the longitudinal strut 4 and having a first and a second end 7, 8. The first end 7 of the transverse strut 5 is fixed to the longitudinal strut 4 such that the transverse strut 5 forms a cantilever.

Furthermore, a force generating device 11 is arranged on the longitudinal support 4 and the swivel arm 6. In this case, the force-generating means 11 for generating a resistance force has a first and a second end 12, 13; the first end 12 of which is rotatably fixed to the longitudinal support 4 and the second end 13 of which is fixed to the rotary arm 6 in a variable and removable manner and can be adjusted stepwise or steplessly.

To be precise, the force-generating device 11 is designed as a hydraulic or pneumatic device, preferably as a hydraulic or pneumatic cylinder.

The force-generating device 11 thus has a cylinder liner 14 and a piston element 15. The cylinder jacket 14 is designed such that it generates a resistance to the piston element 15 moving therein at least in one direction of movement and the cylinder jacket 14 is rotatably fixed to the longitudinal strut 4. The piston element 15 is arranged in a variable and removable manner on the rotary arm 6 and can be adjusted stepwise or steplessly; the second end 13 of the force-generating device 11 is mounted on the swivel arm 6 in a variable and detachable manner by means of an adjustment unit 16 and can be adjusted stepwise or steplessly.

As shown in fig. 2A-2C, the adjustment unit 16 is designed to be movable along the rotating arm 6 and to be detachably fixed with the rotating arm 6.

Fig. 2A-2C furthermore show that the power station 1 has a front side V, opposite to which is a rear side H, and a first side, i.e. a left side L, and a second side, i.e. a right side R, opposite to the first side, the left side L.

The front side V of the power station 1 is arranged and mounted in such a way that the user can easily find the means 17 for operating the power station 1, in particular the support means 19, on the front side V.

The means 17 for operating the power station 1 comprise support means 19 and a pull-down bar 17 located on the front side V. As described above, the power station 1 has a transverse strut 5, which is spatially directed from the first left side L towards the second right side R, as shown in fig. 2A-2C. In other words, the direction of the transverse strut 5 is the same as or horizontal to the direction of the room floor.

In this case, the longitudinal struts 4 form an angle with the transverse struts 5 of between 70 and 110 degrees, in particular 90 degrees, with one end of the longitudinal struts 4 facing the floor and the other end facing the ceiling of the room.

Referring to fig. 2A-2C, it can also be seen that, as previously described, the swivel arm 6 has a first and a second end 9, 10, wherein the first end 9 of the swivel arm 6 is rotatably fixed to the transverse strut, in particular at the second end 8 of the transverse strut 5.

A deflection wheel 17 is arranged at the second end 10 of the swivel arm 6 for deflecting the tension cord, by means of which the force generated by the user can be transmitted to the swivel arm 6.

Fig. 2A-2C also show that the swivel arm 6 is designed to be curved or arc-shaped; in other words, the shape of the rotating arm 6 is a segment of a circular ring.

Furthermore, the length of the transverse strut 5 plus half the width B of the longitudinal strut 4 corresponds to at least half the length of the swivel arm 6. In this case, the width B of the longitudinal strut 4 is the distance from the left first face L to the right second face R. While the length of the rotating arm 6 is determined along its curve or along a line segment directly connecting the two ends 9 and 10 of the rotating arm 6. In other words, in the initial state in which the power station is not in use, the swivel arm 6 is similar to the lever arm of a lever balance, intersecting the longitudinal strut 4 transversely, with the point of intersection.

The object of the present invention is to apply the force generating means used in the above known power stations of the same kind to a more compact platform power station.

The applicant of the present invention thus implements a power station for a user to exercise strength by adapting such a power station to have a platform upon which the user can stand or sit while performing the strength exercise. One or more resistance devices may be disposed within or below the platform. The resistance device is used for generating resistance and comprises a rotating arm and a force generating device matched with the rotating arm. An adjusting unit is used for changing the application point of the force generating device on the rotating arm so as to adjust the resistance steplessly or step by step.

According to the invention, a power station for a user to perform a strength exercise comprises a platform for placing the power station on a floor of a room, wherein the platform has an upper surface on which the user of the power station can particularly stand or sit and lie. The platform also serves as a mechanical frame for the strength station for securing the structural components and ensuring structural stability.

The size and nature of the upper surface facilitates a user to stand, sit, kneel or lie in a stable posture while performing strength exercises while being compact enough to be used in a private living area. For example, the top view of the platform may be rectangular with a long side length of about 0.5 to 1.5 meters. The short side length is preferably 0.4 to 1.0 meter. The height of the platform after placement, i.e. the distance to the upper surface, is preferably 0.1 to 0.3 meter, the upper surface preferably being flat and parallel to the ground. By "rectangular" is not meant that the platform must be strictly rectangular. For example, the shape may also have rounded corners and/or curved side edges, or the platform may even be rounded, for design considerations.

For example, the upper surface may be made of a solid wood board or composite material. Alternatively, a single metal plate may be used. For improved stability, the underside of the metal plate may have a three-dimensional structure corresponding to the upper surface.

For placement on a preferably level ground, the platform preferably has a plurality of support feet, such as four support feet. In particular, a support leg can be provided at each corner of the rectangular platform. By means of the support feet, the upper surface can be parallel to the ground, preferably at a distance of 0.1 to 0.3 meters. The length of the support feet can be adjusted separately, for example stepwise or steplessly, in order to adjust the distance to the ground. In an alternative embodiment, the platform may have three support feet, which is advantageous in that the platform is prevented from rocking. The four supporting feet have the advantage of preventing the platform from tipping over. In another embodiment, the support feet may also be designed as rails and/or rollers to facilitate transport or movement of the platform over the ground.

According to the invention, the power station has at least one resistance device for generating a resistance force. The resistance device comprises a rotating arm, a force-generating device matched with the rotating arm and an adjusting unit for changing the force-applying point of the force-generating device on the rotating arm. The resistance value can be adjusted by changing the point of application. In the preferred embodiment, the force station has an adjustment means, such as a lever or knob or similar mechanism, for adjusting the force. Preferably, the adjustment means is arranged such that the user can adjust the force when the power station is placed on the floor. For example, the adjustment means may be arranged at the side of the platform. The adjusting means are associated with the action of the adjusting unit.

In a preferred embodiment, the force station may have two or more resistance devices for generating resistance. In this case, preferably, the adjustment unit is adjustably connected to the swivel arm in order to adjust the resistance required for the user's strength exercise step by step or steplessly.

The adjustment unit is adjustably connected to the swivel arm to adjust the resistance required for the user's strength exercise step by step or steplessly. The adjustment can be performed using the adjustment device described above.

According to the invention, the resistance means are arranged on the underside of the upper surface of the platform. The expression "on the underside of the upper surface of the platform" does not mean that the resistance means must be in close proximity to the underside of the upper surface of the platform. For example, an embodiment is conceivable in which the resistance means are arranged on an auxiliary frame or an auxiliary support, wherein the auxiliary frame or the auxiliary support is located below the upper surface of the platform and at a distance from the underside of the upper surface of the platform. In other words, the resistance means is located between the ground and the underside of the upper surface when the power station is in the fully seated condition. In this way, all movable parts of the resistance device (except for the tension ropes described later) can be arranged on the underside in a protected manner. Thereby minimizing the risk of injury to the user. In addition, the resistance device can be protected from harmful effects.

In a preferred embodiment, the platform side support legs may be closed by respective side walls such that the resistance means is housed within the enclosure defined by the side walls and the upper surface. In another preferred embodiment, the platform may take the form of a rectangular parallelepiped box. Thus, in such embodiments, the platform also has a lower bottom surface.

On the underside of the platform, a support column may be arranged parallel to the upper surface. For example, the support posts may be directly secured to the underside of the upper surface. Alternatively, the support post may be secured to an optional bottom surface. Alternatively, the struts may be secured using support feet. The struts are used primarily as mechanically fixed frame structures for securing the components of the resistance device. The support is therefore preferably fixedly connected to the platform. In addition, the support posts can also be used to increase the mechanical strength of the upper surface.

The rotating arm has a first end and a second end and is disposed parallel to the upper surface of the platform. Preferably, the first end of the swivel arm is rotatably fixed to the post. As used herein, "rotatable" means that the rotating arm can perform rotational movement about a fixed point about the support post in a plane parallel to the upper surface.

At the second end of the swivel arm, a bracket for fixing one end of the tension cable or a deflection wheel for deflecting the tension cable is preferably arranged. The force generated by the user can be transmitted to the swivel arm by means of a pull cord through a bracket or deflection wheel.

The force generating means for generating a resistance force has a first end and a second end. Preferably, the first end is rotatably fixed to the platform, preferably to the post. By "rotatable" is meant that the force-generating means is capable of rotational movement in a plane parallel to the upper surface, about a fixed point with the support post as a fulcrum.

Preferably, the second end of the force generating means is secured to the rotating arm in a variable and removable manner and may be adjusted stepwise or steplessly. The force can be adjusted by changing the fixed position of the second end of the force generating means on the rotating arm. The aforementioned adjusting device can be used in particular for this purpose.

Preferably, the second end of the force generating means on the rotating arm may be fixed in a variable and detachable manner by means of an adjustment unit and may be adjusted stepwise or steplessly. Thus, different resistances can be set.

In other words, the adjusting unit is preferably designed to be movable along the rotary arm and is also fixed to the rotary arm in a variable and detachable manner. In this way, different resistances can be set.

The force-generating device is preferably designed as a hydraulic or pneumatic device, preferably as a hydraulic cylinder or air cylinder. The force-generating device may furthermore have a cylinder liner and a piston element.

Preferably, the cylinder liner is designed to generate a resistance to the piston element moving therein at least in one direction of movement. Therefore, if a force is generated in only one direction, a training effect is generated in only that direction.

It is furthermore advantageous if the cylinder liner is rotatably fastened to the support column. Alternatively, the cylinder liner may be directly rotatably fixed to the platform, for example to the underside of the upper surface or to the support feet. The rotatability allows the force generating device to be rotated relative to the platform.

It is also advantageous if the piston element on the swivel arm is arranged in a variable and detachable manner and can be adjusted stepwise or steplessly. In this way, the resistance can be varied almost at will and can be configured as desired according to the individual requirements. In a preferred embodiment, the resistance means has only one rotating arm. This solution simplifies the construction of the power station, reduces the manufacturing costs and minimizes the space requirements. Preferably, the rotating arm is arranged towards the short side of the rectangular upper surface, and the force generating means is preferably arranged along the long side of the rectangular upper surface. The ratio of the short side to the long side can be used to specify the adjustment range of the applied force.

By changing the relation between the length of the short side and the length of the long side of the rectangle, different basic configurations can be realized according to the acting resistance. In short, the basic principle is that the shorter the lever, the greater the force that the user needs to apply. At the same time, the above-described modifications also contribute to space saving, so that the power station can be designed with more mechanical stability.

Preferably, the upper surface of the platform has a hole therein through which the tension cord may be guided from the force generating device up to the user.

Preferably, the force station has at least two tension ropes, which can be led to the lower side through a hole in the upper surface, respectively. Preferably, the spacing of the plurality of holes should be such that the lever is oriented to facilitate strength exercises. In another preferred variant, the force station may also have only one tension cord, which may be led out through a hole in the center of the upper surface, for example.

The first ends of the tension ropes may be connected to the force-generating devices, respectively.

Preferably, the second ends of the tensile cords each have a handle. The user of the power station can hold the handle and apply tension while exercising.

Advantageously, the plurality of tensile cords may be pulled independently of each other for strength exercises. To this end, the ropes may be guided to the underside of the upper surface by means of deflection wheels or the like without mutual influence and connected to one or more resistance devices.

The upper surface of the platform may have a support cushion upon which a user may lie, sit or kneel to support the user's training position during strength exercises.

Furthermore, it is advantageous if at least one of the swivel arms is designed to be curved or arc-shaped and/or if the shape of at least one swivel arm is a segment of a circular ring.

The invention will be described in more detail below with reference to examples and in connection with the accompanying drawings. The following schematic diagrams illustrate:

FIG. 1 is a front view of a known similar type of power station;

FIGS. 2A-2C are several views of another known similar type of power station;

figures 3A-3B are perspective views of a power station according to one embodiment of the present invention;

FIG. 4 is a plan view of a power station according to an embodiment of the present invention;

FIGS. 5A-5B are perspective views of another embodiment of the present invention;

figure 6 is a perspective view of another embodiment of the present invention.

In the following description, the same reference numerals are used for the same objects.

Figures 3A, 3B and 4 show a first embodiment of a power station 1 according to the invention. Fig. 3A and 3B are perspective views of the power station 1, respectively, wherein fig. 3B omits the upper surface 2a of the platform of the power station 1 to show the internal components. Fig. 4 shows a top view of the power station, omitting the upper surface 2a as in fig. 3B.

According to a first embodiment of the invention, a power station 1 for a user to exercise strength comprises a platform for placing the power station 1 on the floor of a room. The platform has an upper surface 2a which is rectangular in plan view and on which a user of the power station 1 can particularly stand or sit. The platform also serves as a mechanical frame for the power station 1 for securing the components and ensuring structural stability.

The size and characteristics of the upper surface 2a facilitate a user standing, sitting, kneeling or lying in a stable posture while performing strength exercises, while being compact enough to be used in a private living area. In the schematic view of fig. 3B, the upper surface 2a is omitted in order to see the components below the power station 1.

The length of the long side of the rectangular platform is about 1 meter. The short side length is about 0.5 meters. The height of the platform after placement, i.e. the distance between the upper surfaces 2a parallel to the ground, is about 0.2 meters.

For placement on a preferably level ground, the platform has four support feet 3. At each corner of the rectangular platform there is a support foot 3. By means of the support feet 3, the upper surface can be parallel to the ground at a distance of about 0.1 to 0.3 meters. The length of the support feet 3 can be adjusted separately, for example stepwise or steplessly, in order to adjust the distance to the ground. The four support feet 3 have the advantage of preventing the platform from tipping over.

The example power station 1 has a resistance device for generating resistance. The resistance means comprise a swivel arm 6, a force-generating means 11 cooperating with the swivel arm 6 and an adjustment unit 16 for changing the point of application of the force-generating means 11 on the swivel arm 6. The resistance value can be adjusted by changing the point of application. The power station 1 has an adjusting device, which in this embodiment is designed as an actuating lever for adjusting the force. The adjustment means are arranged so that the user can adjust the force when the force station 1 is placed on the floor. In this embodiment, the adjustment means are arranged at the side of the platform. The adjusting means are associated with the action of the adjusting unit 16.

The adjusting unit 16 is adjustably connected to the swivel arm 6 to adjust the resistance required for the user's strength exercise step by step or steplessly. The adjustment can be performed using the adjustment device described above.

The resistance means are arranged on the underside of the platform upper surface 2 a. In other words, when the power station 1 is in a fully seated condition, the resistance means is located between the ground and the underside of the upper surface 2 a. In this way, all movable parts of the resistance device (except for the tension ropes described later) can be arranged on the underside in a protected manner. Thereby minimizing the risk of injury to the user. In addition, the resistance device can be protected from harmful effects.

A support column 4 is arranged on the underside of the platform parallel to the upper surface. In this embodiment, the support posts 4 are directly fixed to the underside of the upper surface. The struts 4 serve mainly as mechanically fixed frame structures for fixing the components of the resistance device. Thus, the support column 4 is fixedly connected to the platform. In addition, the support posts 4 serve to increase the mechanical strength of the upper surface 2 a. The rotary arm 6 has a first end and a second end and is arranged in parallel on the upper surface 2a of the platform. The first end of the rotary arm 6 is rotatably fixed to the support post 4. By "rotatable" it is meant that the rotary arm 6 is capable of rotational movement about a fixed point about the support post 4 in a plane parallel to the upper surface 2 a.

At the second end of the swivel arm 6 a deflection wheel is arranged for deflecting the pull cord 21. The force generated by the user can be transmitted to the swivel arm 6 by means of the deflecting wheel by means of the pull cord 21.

The force-generating means 11 for generating a resistance force has a first end and a second end. The first end is rotatably fixed to the support column 4. By "rotatable" it is meant that the force-generating means 11 can be rotated in a plane parallel to the upper surface 2a about a fixed point with the support post 4 as a fulcrum.

The second end of the force-generating device 11 is fixed to the swivel arm 6 in a variable and detachable manner by means of an adjustment unit 16 and can be adjusted stepwise or steplessly. The force can be adjusted by changing the fixed position of the second end of the force generating means 11 on the rotating arm 6. The aforementioned adjusting device can be used in particular for this purpose.

In other words, the adjustment unit 16 is designed to be movable along the rotating arm 6 and detachably fixed with the rotating arm 6. In this way, different resistances can be set.

The force-generating device 11 is designed as a hydraulic or pneumatic device, preferably as a hydraulic cylinder or an air cylinder. The force-generating device 11 furthermore has a cylinder liner 14 and a piston element 15.

The cylinder liner 14 is designed to create a resistance to the piston element 15 moving therein at least in one direction of movement. Therefore, if a force is generated in only one direction, a training effect is generated in only that direction.

Furthermore, the cylinder liner 14 is rotatably fixed to the support column 4. The rotatability allows the force-generating device 11 to be moved in rotation relative to the platform. Thus, the end of the cylinder liner 14 that is fixed to the support column 4 corresponds to the first end of the force-generating device 11.

The piston element 15 is arranged in a variable and detachable manner on the swivel arm 6, which can be adjusted stepwise or steplessly. In this way, the resistance can be varied almost at will and can be configured as desired according to the individual requirements. The end of the piston element 15 fixed to the swivel arm 6 thus corresponds to the second end of the force-generating means 11.

In the described embodiment, the resistance means has only one rotating arm 6. This solution simplifies the construction of the power station 1, reduces the manufacturing costs and minimizes the space requirements. In this case, the rotating arm 6 is arranged toward the short side of the rectangular upper surface 2a, and the force generating means 11 is arranged along the long side of the rectangular upper surface 2a. The ratio of the short side to the long side can be used to specify the adjustment range of the applied force.

The power station 1 has at least two tension ropes 21 which are led to the lower side through a hole in the upper surface 2a, respectively. The spacing of the holes allows the lever orientation to facilitate strength exercises. The first ends of the tension ropes 21 are connected to the force-generating means 11, respectively. However, it is also conceivable to provide only one tension cord on the power station, which tension cord can be led to the underside through a hole, for example in the center of the upper surface.

Advantageously, a plurality of tensile cords 21 may be pulled independently of each other for strength exercises. For this purpose, the tension ropes 21 can be guided to the upper surface underside 2a without mutual influence by means of deflection wheels or the like 17 and connected to one or more resistance devices.

The second ends of the pull cords 21 each have a handle 22. The user of the power station 1 can grasp the handle 22 and apply a pulling force during exercise. The user can stand, sit, lie or kneel on the platform or on the upper surface 2 of the power station 1 for strength exercises. For example, the user may pull both tensile cords upward or obliquely upward at the same time. In particular, the user may hold the handle 22 with his or her hand or pull the handle 22 with his or her foot. Advantageously, the user takes his own weight as a counterweight, which stabilizes the platform. By means of deflection wheels or the like, the force is converted along the tensile cord 21 into a movement of the piston element 15 in the cylinder jacket 14. For example, in the embodiment of fig. 3A, 3B and 6, the second end of the tensile cord 21 is provided with a handle 22.

Fig. 5A and 5B show further embodiments of the power station 1. On the platform of the power station a support device 19 is arranged, which is designed as a vertical support with a horizontal grip.

For example, a user of the power station 1 may grasp the support device 19 and perform leg exercises while performing the strength exercises. To this end, the tension cord 21 may be secured to the user's leg, foot or other part of the body by means of a suitable strap, for example by means of a snap-lock 22a or similar means. In a preferred embodiment, one or both of the tension cords 21 may be secured using a belt or chest strap or the like that is worn by the user while performing the strength exercise, for example, while performing the torso and/or back muscle exercises.

In fig. 5A, the support means 19 is fixed in the middle of the short side of the rectangular platform. In fig. 5B, the support means 19 is fixed in a position intermediate the long sides of the platform.

Figure 6 shows a further improved embodiment of the power station 1 of the invention. The power station 1 in fig. 6 also comprises a seating area 19. The user can sit, lie or kneel on the seating area 19 while performing the strength exercise using the tension cord 21 with the handle 22. The seating area 19 is preferably fixedly or removably attached to the platform.

In a preferred embodiment, the seating area 19 of the power station 1 can be designed to be tiltable. Preferably, the seating area 19 can be inclined stepwise or continuously in the range of 0 ° to 90 °, e.g. an inclination of about 45 ° of the seating area 19 of the power station 1 can be used as a resting surface and support surface for the back of a user in order to perform exercises such as back exercises.
