Background technique

Functional training is a category of exercise that involves training the body for activities performed in daily life. Functional training leads to better joint mobility, joint stability, and more efficient movement patterns including strength and balance. The origin of functional training is derived from physical or occupational rehabilitation using exercises that mimic normal activities. The use of traditional strength machines delivers a single plane or fixed pattern of motion that only targets specific muscles and does not necessarily have anything to do with the movements people make in their regular activities.

detailed description

The following detailed description is of the best currently contemplated modes of carrying out the exemplary embodiments of this invention. The described embodiments are not taken in a limiting sense, but merely for the purpose of illustrating the general principles of the invention, as the scope of the invention is best defined by the appended claims.

A number of inventive features are described below which may each be used independently of the other or in combination with other features. In general, some embodiments of the present invention generally provide exercise equipment that allows a user to experience natural progressive movements. Such devices may include the circuitry of a separate cable-driven machine that allows the user to define the course of the exercise.

Movement using the arcuate progression of certain embodiments triggers complex muscle interactions including core stabilization and peripheral muscles. Coupling the arc movement of certain embodiments with unrestricted cable-driven action improves balance and functional movement, ensures complex muscle interaction, and supports the user in an optimal biomechanical position throughout the exercise.

Such functional movements include things like manually opening or closing a garage door, replacing or removing a heavy object on a high shelf, placing or pulling an object in or out of the trunk of a car, Get up or sit on a chair, get in or out of the tub, pull a water hose across the yard, push a lawn mower, or even lift and pick up a child or pet.

Several more detailed embodiments of the invention are described below. Section I provides a conceptual description of the theory of operation of some embodiments and a description of an example design process. Section II then describes a number of specific machines that may be provided by some embodiments.

I. Theory of Operation

Subsection I.A provides a conceptual description of various elements associated with body positions in some embodiments. Subsection I.B then describes a number of resistive elements included in some embodiments. Finally, Subsection I.C describes an example design implementation for a particular machine.

A. Body position element

Some embodiments provide a fixed user support. Such supports may be generally "L" shaped and may allow a user to sit or recline on the equipment while having his or her body supported in an optimal position for exercising. Different embodiments may include different specific support elements. For example, such supports may have different angles between the seat portion and the back portion of the support. As another example, different embodiments may include different sets of pads or other suitable elements.

In some embodiments, various elements of the fixed support may be adjustable (eg, a seat height setting may be selected from a plurality of options).

Some embodiments provide a first body movement element. Such elements may include carriage systems driven and tracked via linear stabilizing shafts. Additionally, some embodiments may include a second body movement element. Such elements may include a fixed post or other suitable support and an attachment element movable along the post such that the fixed user support remains in place as the support moves along the first body movement element. proper body position.

In some embodiments, the body moving element may be at least partially adjustable. For example, the user can set a start or end point along the movement path, the user can adjust the angle of the body movement element relative to the user support, etc. In some embodiments, adjustable elements may allow a user to align a joint with a machine feature (eg, align a knee with a pivot point on a leg curl machine).

Such body movement elements may allow the user to maintain a natural body arc progression during movement. Plus, the system provides consistent, smooth resistance throughout your workout.

By combining multiple body movement elements, users can benefit from an "unrestricted" progression of compound muscle movement, activating vital core stabilization muscles to replicate "real life" functional activity.

B. Resistance element

Some embodiments may include cable-actuated weight stack resistance movement elements. Many embodiments may include a pair of handles (and/or other suitable user interface elements, eg, foot pedals, levers, rollers, etc.), where each handle is attached to a cable end. Free cable ends may allow the user to move each handle along any path, which may allow for more comfortable movement and/or engage additional muscle groups.

Each cable may utilize a set of pulleys and/or be connected to one or more other cables or elements. In some embodiments, in addition to using the cable system to move selected weight stack resistance elements, the cable system can also be used to move the user along the path of movement defined by the body movement elements described above. .

Some embodiments may be configured such that the user's body weight provides additional resistance to the weight stack resistance. Alternatively, some embodiments may be configured such that the user's body weight provides assistance in moving the weight stack resistance. Some embodiments may be configured such that the amount of additional resistance and/or assistance may vary across the path of travel.

Those of ordinary skill in the art will recognize that a number of other specific resistance elements or optional loads may be included in some embodiments (eg, body weight only, resistance bands, free weight attachment points, etc.).

C. Example design

The features described above will be explained with reference to the example machine of FIGS. 1-15 . A first example is a chest exercise machine 100 that can be used for chest presses and/or chest expansion exercises. This example will describe a chest press exercise using the chest machine.

FIG. 1 illustrates a side view of a chest press machine 100 in a starting position according to an exemplary embodiment of the present invention. Such a starting position may be a resting position of the machine other than the starting position of the exercise. In other words, the machine can naturally remain in the starting position when the machine is not in use. FIG. 2 illustrates a side view of the chest press machine 100 in an end position. FIG. 3 illustrates a side view of the chest press machine 100 showing the relative arrangement of the starting and ending positions.

Figure 4 illustrates a side view of the chest press machine 100 in the starting position during use. Figure 5 illustrates a side view of the chest press machine 100 in the end position during use. Figure 6 illustrates a side view of the chest press machine 100 showing the relative arrangement of the starting and ending positions during use.

FIG. 7 illustrates a top view of the chest press machine 100 in the starting position during use. Figure 8 illustrates a top view of the chest press machine 100 in the end position during use. FIG. 9 illustrates a top view of the chest press machine 100 showing the relative arrangement of the starting and ending positions during use.

FIG. 10 illustrates a perspective view of the chest press machine 100 in the starting position. FIG. 11 illustrates a perspective view of the chest press machine 100 in the end position. Figure 12 illustrates a perspective view of the chest press machine 100 in the starting position during use. Figure 13 illustrates a perspective view of the chest press machine 100 in the end position during use.

As shown, the cable resistance machine 100 can place the user in a rested starting position and deliver a natural forward and return arcuate progression that applies a continuous and equal amount as the handle moves away from the user's body. resistance. These machines engage the user's chest, shoulders, triceps, and core stabilization muscles during movement.

The machine 100 may include: a fixed user support having a seat 110 and a back support 120; a first moving element having a carriage 130 and a track 140 (and/or other suitable elements such as shafts) a second moving element having a moving attachment element 150 and a fixed post 160 , a set of handles 170 , a weight stack 180 and a cable system 190 .

The machine frame 100 may be formed by a number of suitable elements, such as cross bars, tubes, brackets, and the like. As shown, the frame elements may be arranged in a number of suitable ways. A number of frame elements may be fixed position elements for supporting moving elements, eg user supports (via moving elements), weight stacks, cables, etc. Moving elements such as pulleys may be attached to the frame and included as part of the resistance path used by the machine.

The seat 110 and back support 120 may be arranged in any suitable manner (eg, at different lengths, connection angles, etc.). Additionally, in this example, the user support may include a footrest. In some embodiments, the support can include adjustable elements that allow the user to align joints with machine features (e.g., pivot points on knee and leg curl machines) and/or adjust user position ( For example, by raising or lowering the seat 110 to adjust the user's height).

The user support defined by the seat 110 and the back support 120 may include a pivot axis associated with the connection to the bracket 130 . Similarly, attachment element 150 may include a pivot shaft. Thus, as shown, the angle of the user support relative to other machine components may vary along the path of travel while the position of the user relative to the user support remains constant.

In some embodiments, the second moving element may include a component having one or more bending angles and multiple pivot points. In some embodiments, a first pivot point may be associated with the attachment of one end of the angled member to the machine body and a second pivot point may be associated with the second end of the angled member to a fixed user support. associated with the attachment of the component. In some embodiments, the second mobile element may be integrated with the user interface element. An example of this configuration is described below with reference to FIGS. 29 and 42 , for example.

Carriage 130 may be any set of components that may allow movement of the carriage along track 140 . This example uses carriage rollers, and other embodiments may include elements such as linear bearings, sliders, etc. In some embodiments, the first moving element may include one or more resistance elements (eg, linear resistance rods).

In this example, track 140 is parallel to the ground, while post 150 forms an obtuse angle with seat 110 . Different embodiments may include different specific configurations. For example, an alternative chest press machine with an inclined track is described below with reference to FIG. 14 .

The path of movement along track 140 may be at least partially defined by properties of the track (eg, slope, length, etc.). Similarly, the path of travel along a column 160 may be at least partially defined by properties of the column (eg, slope, length, etc.). Additionally, the path of movement of the user may be defined at least in part by the arrangement of the pivot axis relative to the attachment element 150 or the seat back 120 and/or the arrangement of the pivot axis relative to the bracket 130 or the seat 110 . In some embodiments, any or all of these elements can be adjusted by the user (eg, the slope of the track can be changed, connecting elements can be repositioned, etc.).

FIG. 14 illustrates a side view of an alternative chest press machine 100 in a starting position according to an exemplary embodiment of the present invention. Figure 15 illustrates a perspective view of the alternative chest press machine 100 in the end position during use.

As noted above, the machine 100 may include: a secured user support having a seat 110 and a back support 120 ; a set of handles 170 ; a weight stack 180 and a cable system 190 .

In this example, the first moving element comprises a linear bearing acting as a carriage 130 and an associated shaft acting as a track 140 . The second moving element comprises a moving attachment element 150 and a fixed post 160 . In this example, column 160 is located within a frame member of machine 100 .

In this example, track 140 slopes upward as movement progresses, while post 160 is aligned at an obtuse angle compared to seat 110 .

Additionally, the example of FIGS. 14-15 includes a weight stack 180 that is placed to the side of the user support. Such an arrangement may allow a user to adjust the amount of resistance while sitting on machine 100 . Additionally, such an arrangement can reduce the floor space required by the machine.

A single machine can be used to perform multiple exercise moves. In some embodiments, the machine can be adjusted in various ways (for example, support arms or other features can be arranged so that cables and/or handle positions can be changed, support angles or positions can be changed, moving elements can be repositioned etc.) to make several different moves.

Alternatively, the user can apply different movement paths to use the same machine for different movements without any adjustment of the machine itself. For example, by changing the position of the arms, angle of the elbows, etc. the user can perform a chest expansion move instead of a press move.

Although the theory of operation has been described with reference to specific machines, those of ordinary skill in the art will recognize that different machines can be implemented in many different ways. Several such machines are described in Section II below.

II. Exemplary Machine

Subsection II.A provides a conceptual description of the leg press machine of some embodiments. Next, Subsection II.B describes the seated leg curl machine of some embodiments. Subsection II.C follows the description of the leg extension machine of some embodiments. Finally, Subsection II.D describes a number of other machines or elements that may be used by some embodiments.

A. Leg press

16-18 illustrate side views of the leg press machine. 19-24 illustrate side and top views of the leg press machine during use. 25-26 illustrate perspective views of the leg press machine. 27-28 illustrate perspective views of the leg press machine during use.

In this example, the cable resistance machine places the user in a seated position with the legs extended straight out and placed on the footrests. During the movement, the user pushes out on the board, while in the simultaneous movement, the upper and lower parts of the body stretch away from each other in a natural forward and return arc, exerting a continuous and equal amount of pressure. resistance. Additionally, the user's quadriceps, hamstrings, lower back, calves, and core stabilizers are all engaged during the movement.

In this example, the track slopes upward as the movement progresses, while the posts are aligned at an acute angle compared to the seat. In this example, the resistance element comprises a flat footrest coupled to a cable system via a multi-point connection element as shown. In some embodiments, the footrest may be curved and/or modified from the example shown.

B. Seated Leg Curl

29-31 illustrate side views of a seated leg curl machine. 32-37 illustrate side and top views of the seated leg curl machine during use. 38-39 illustrate perspective views of a seated leg curl machine. 40-41 illustrate perspective views of the seated leg curl machine during use.

In this example, the cable resistance machine places the user in a seated position, where the legs rotate as the user pulls through one or both legs in a downward motion to rotate the stuffing arm back under their body. The section extends directly in front over the rotatable filling arm. The user's upward rotation exerts a continuous and equal amount of resistance in a natural forward and backward arcuate progression. Additionally, the user's quadriceps, glutes, knees, muscles and tendons, lower back and core stabilizers are all engaged during the movement.

The track in this example is flat compared to the ground, while the second moving element includes multiple pivot points along the part and is integrated into the resistance path as shown. Thus, when the user makes this movement, the body position is automatically adjusted by the position of the components, as defined by the position of the user's engaging elements. Different embodiments may include different specific configurations. For example, an alternative leg curl machine may have an inclined track.

The machines of Figures 29-41 illustrate examples of improved functionality using systems of some embodiments. Tilting moves can help some users make full moves.

c. Leg extension

42-44 illustrate side views of the leg extension machine. 45-50 illustrate side and top views of the leg extension machine during use. 51-52 illustrate perspective views of the leg extension machine. 53-54 illustrate perspective views of the leg extension machine during use.

In this example, the cable resistance machine positions the user in a seated position with the legs bent back under the seat and padded rotatable arms. During movement, the user lifts one or both legs in an upward motion to rotate the padded arms forward and arc upward in front of the body. During this exercise, the user rotates upward in a natural progression of forward and return arcs, applying a continuous and equal amount of resistance. Additionally, the user's hamstrings, hip flexors, knee joints, muscles and tendons, lower back and core stabilizers are all engaged during the movement.

The track in this example is flat compared to the ground, while the second moving element includes multiple pivot points along the part and is integrated into the resistance path as shown. Thus, when the user makes this movement, the body position is automatically adjusted by the position of the components, as defined by the position of the user's engaging elements. Different embodiments may include different specific configurations. For example, an alternative leg extension machine may include an inclined track.

The machines of Figures 42-54 illustrate examples of improved functionality using systems of some embodiments. Users may find it easier to achieve full stretch when leaning back as the exercise progresses.

D. Alternative Implementations

Those of ordinary skill in the art will recognize that the machines described in subsections II.A-II.C are presented for exemplary purposes and that different embodiments may be implemented in many different ways.

For example, some embodiments may provide machines (eg, glute machines) that target different muscle groups than those described above. As another example, different embodiments may include different cable and/or handle configurations than those shown (eg, instead of using a separate handle, some embodiments may use a rod). Additionally, the various embodiments can be configured in many different ways (eg, with different slopes, different connection elements, different resistance elements, etc.). In some embodiments, the various features are configurable by the user in a variety of different ways (eg, by adjusting the length of elements, by replacing one or more elements, etc., using different connection points).

The foregoing relates to illustrative details of exemplary embodiments of the invention and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
