Description

treadmill

technical field

The present invention relates to exercise and fitness equipment, in particular to a foldable treadmill.

Background technique

Treadmill is very popular a kind of indoor sports equipment at present. Due to the large size and large footprint of general treadmills, they are often designed in a foldable form (especially for general household use), allowing users to fold them into volume or size when not in use. The contracted form with a small footprint will avoid occupying too much space and ground at ordinary times and hinder general indoor activities.

Now the most common folding form of the treadmill is to fold the treadmill upwards with the front end as the axis. In this folding form, the treadmill is usually folded up to an upright or slightly upright state, and Enter the scope of the side armrests of the treadmill (for the user to hold), thereby releasing the ground originally occupied by the treadmill, and shortening the front and rear length of the treadmill to reduce the space volume. However, due to the large front and rear lengths of the aforementioned side armrests, the folded shape of the treadmill is not shrinkable enough. Even if it is placed against a wall, it will still protrude to a certain thickness, and it is difficult to store it in a narrow space.

Some treadmills make the running platform almost vertical to the ground after being folded, and the side armrests and instruments can also be turned down or up to a vertical state, so that they are upright and flat after being fully folded, and the space occupied Volume is minimized. However, in this folding method, the user must go through two (or even three) actions, that is, turning the running platform up to the upright state, and turning the side armrests and instruments to the vertical state to complete the folding. The folding action is also the same when unfolding from the folded state, so it is time-consuming and inconvenient to use. If it is designed in the form of electric folding, although the user does not need to apply force to fold or unfold, the treadmill needs to be equipped with two sets of driving devices (such as motors and screw linkage mechanisms) to drive the treadmill and side armrests to rotate respectively. make the cost higher.

Detailed ways

The structure, function and characteristics of the present invention will be described in detail by citing the following embodiments in conjunction with the accompanying drawings.

The treadmill provided by a preferred embodiment of the present invention is generally used to be installed indoors against a wall, and it can be changed between a use state and a folded state: in the use state (as shown in Fig. 1, Fig. 2 As shown), the treadmill 1 can be used for the user to perform exercises such as walking and running in situ; in the folded state (as shown in Figure 8 and Figure 9), the treadmill 1 is folded into an upright flat shape close to the wall, empty Out of the indoor space and ground occupied when in use.

As shown in Fig. 1 and Fig. 2, the treadmill 1 mainly includes a base 10 located at a corner, a running platform 20 connected behind the base 10, a support rod group 60 extending upward from the front end of the running platform 20, And an armrest group 70 and an instrument group 80 arranged at the top of the support bar group 60 . In addition, as shown in FIG. 3 and FIG. 4 , a linkage mechanism 90 is also connected between the treadmill 20 and the support bar set 60 , the armrest set 70 and the instrument set 80 so that they can drive each other (later details).

The base 10 is locked at the corner between the ground G and the wall W in the room, and has a crossbar 12 fitted on the bottom edge of the wall G, and a left side extending backwards from the two ends of the crossbar 12 against the ground G. , the right two side bars 11, and the left and right two vertical bars 13 protruding upwards from the two ends of the cross bar 12 .

The treadmill 20 is generally rectangular, and its front end is pivotally connected with the base 10, which jointly constitute a basic unit that sits on the ground G when in use. In the state of use, the treadmill 20 is generally in a lying posture, as shown in Figures 1 to 3; in the folded state, the treadmill 20 is folded upwards into an upright posture (note: the aforementioned "front end" at this time located below), as shown in Figures 7 to 9.

In this embodiment, the frame of the treadmill 20 is made up of an auxiliary frame 21 directly pivoted with the base 10 and a main frame 31 pivotally connected with the auxiliary frame 21, and the connection between the main frame 31 and the auxiliary frame 21 An elevating device 40 is provided between them to adjust the angle of the treadmill 20 (the main frame 31 ) relative to the ground G in the state of use.

The auxiliary frame 21 has left and right side bars 22 parallel to each other and a cross bar 23 (as shown in FIG. 2 ) connecting the front ends of the two side bars 22 . The rear end of the side bar 11 of 10 makes the auxiliary frame 21 deflect up and down with the front end as the axis.

The main frame 31 has left and right two side bars 32 parallel to each other and some cross bars 33 connecting the two side bars 32, and a front drum 34 and a rear drum 35 are pivotally arranged at the near front end and the rear end respectively, two drums 34, There is a running board (not shown) that is elastically supported on the main frame 31 between 35, and an annular running belt 36 that walks around the top side and bottom side of the aforementioned running board is sleeved on the cylinders 34, 35, and at the same time, The front end of the main frame 31 is also provided with a driving motor 37, and its output can drive the front roller 34 to rotate through a driving belt (not shown in the figure), so as to drive the running belt 36 to circle around. The main frame 31 is pivotally connected to the rear end of the side bar 22 of the auxiliary frame 21 with its near front end to the pivot 38 to the left and right, so that the main frame 31 and the auxiliary frame 32 can be relatively deflected with the main frame pivot 38 as the axis center to change The inclination of main frame 31 (as described in the next paragraph). The bottom of the rear end of the main frame 31 is provided with a pair of feet or rollers (not shown) that can be supported on the ground G.

In the state of use, the lifting device 40 can change the angle of the main frame 31 relative to the ground G by changing the relative angle between the main frame 31 and the auxiliary frame 21, thereby setting the user to walk or walk on the treadmill 20. The exercise difficulty of running. The treadmill 20 shown in FIGS. 1 to 3 is in the basic state with the lowest exercise difficulty, and the main frame 31 and the auxiliary frame 21 are roughly parallel to the ground G at this moment. This manual does not provide a diagram of the main frame 31 after the inclination has been changed, and the state will only be described in words below.

The elevating device 40 mainly comprises an elevating motor 41 and a telescopic rod 42 (as shown in Figure 2), the elevating motor 41 is pivotally arranged at the front end center of the main frame 31 by a motor seat (not labeled), and the telescopic rod 42 is formed by A screw rod and a helical tube (not labeled among the figures) that are inserted into each other and are at least partially engaged are formed. Due to the different rotation directions of the lifting motor 41 during operation, the above-mentioned screw rod and coil tube will maintain the same axis and move away from each other or approach each other. In other words, the telescopic rod 42 will be extended or shortened. When the telescopic rod 42 is stretched, the front end of the main frame 31 is forced away from the front end of the auxiliary frame 21, and because the front end of the auxiliary frame 21 is kept at the height of the ground G, the front end of the main frame 31 will gradually rise. The rear end of the frame 21 is pivotally connected to the near front end of the main frame 31, so it can be lifted up accordingly. When the telescopic rod 42 shortens, the front end of the main frame 31 will gradually approach the ground G, and at the same time, the rear end of the auxiliary frame 21 will also lower thereupon. When the lifting motor 41 stopped running, the main frame 31 was limited at the current angle by the telescopic rod 42 and the auxiliary frame 21, and the main frame 31 and the auxiliary frame 21 could not move relative to each other.

It must be noted that the treadmill in the present invention can also use other forms of devices or methods to achieve the function of adjusting the inclination, and even, in another embodiment of the present invention (not shown), the treadmill cannot be adjusted slope.

Different from the above function of adjusting the inclination, as mentioned above, the running platform 20 can also be turned up and down relative to the fixed base 10 with the frontmost auxiliary frame pivot 24 as the axis, so as to change into The reclining position or the upright position when folded. Specifically, the treadmill 20 can rotate between the use position shown in FIG. 3 and the folded position shown in FIG. 7 . When the running platform 20 is in the use position, its long axis is roughly parallel to the ground G;

The treadmill 1 of this embodiment is designed to be folded manually, that is, the user must apply force to turn the treadmill 20 over. In contrast, the present invention can also be designed as an electric folding form (not shown), that is, a set of driving devices that can drive the running platform 20 to turn up and down is added, so that the user can command the aforementioned driving devices to drive running with mechanical energy through electronic signals. The table flips.

On the basis of this manual form embodiment, an auxiliary device 50 is respectively provided on the left and right sides of the front end of the treadmill 20—the present embodiment adopts an air spring (air spring) (a known device) with an elongation tendency, Its opposite two ends are respectively pivoted on the base 10 and the treadmill 20, and the position on the base 10 and the pivot 24 of the treadmill 20 are separated by an appropriate distance, so that when the treadmill 20 is in the use position, The gas springs are relatively short, and the gas springs are relatively long when the treadmill 20 is in the collapsed position. Thus, the auxiliary device 50 can provide pushing assistance when the treadmill 20 is turned upside down, and play a buffering role when the treadmill 20 is turned down. Auxiliary device 50 also can replace with hydraulic cylinder or other energy storage devices. Since this part belongs to the prior art, it will not be described in detail here.

The support rod group 60 includes left and right two support rods 61, and the two support rods 61 extend longitudinally, and the bottom ends are pivotally connected to the front end of the main frame 31 of the running platform 20 through a left and right pivot 62 respectively, and the left and right The right two are coaxial. In addition, a cross bar 63 is connected near the top ends of the two support bars 61 so that the left and right support bars 63 can deflect synchronously relative to the running platform 20 (as shown in FIGS. 3 , 6 and 7 ). Each support rod 61 is a hollow tube body, and is provided with an armrest notch 64 near the top end of its rear side, and is provided with a connecting rod notch 65 in addition, and two notches 64,65 are all connected with the support rod 61. The hollow interior is connected.

The armrest set 70 includes two side armrests 71 located on the left and right sides respectively. Each side armrest 71 is generally in the shape of a straight rod, has an opposite inner end and an outer end, and passes through a left and right pivot 72 (As shown in Figure 3) a predetermined position close to the inner end is pivotally connected to the top of the corresponding support rod 61, and the left and right handrails are coaxial and can rotate between a use angle and a folding angle. Specifically, when the side armrests 71 are at the use angle, the pivot shaft 72 inside the support rod 61 passes through the armrest notch 64 and protrudes backward to the outside of the support rod 61 (as shown in FIGS. 4 and 5 ). Show). When the side armrest 71 is at the folded angle, it generally extends longitudinally downward from the position of the pivot 72 and is completely accommodated in the hollow interior of the support rod 61 (as shown in FIG. 7 ).

The instrument cluster 80 includes an instrument shaft 81 pivotally connected between the tops of the left and right support rods 61 , and an instrument body 82 fixed at the center of the shaft 81 . The appearance of the instrument main body 82 is generally a flat box, and the central circuit connected with the electronic devices such as the driving motor 37 and the lifting motor 41 (or its driving control circuit) is provided inside, and the instrument interface 83 is provided on the front, including a display for running. A display (not shown) for various operating parameters of the machine 1, and buttons (not shown) for the user to input various commands and data. Since this part is not the focus of the present invention, it will not be described in detail here.

In this embodiment, there is another middle armrest 73 fixed on the instrument shaft 81, which has a straight part extending left and right, and is roughly on the same plane as the flat instrument main body 82, but is respectively located on the sides of the instrument shaft 81. opposite sides.

As shown in FIG. 3 to FIG. 5 , the linkage mechanism 90 is connected among the treadmill 20 , the support bar set 60 , the armrest set 70 and the instrument set 80 , so that they can restrain and drive each other. The linkage mechanism 90 includes: two base connecting rods 91, two supporting connecting rods 93, two driving rods 95, two armrest connecting rods 96 and two instrument connecting rods 97, and the above components are respectively arranged on the left and right sides in a symmetrical manner , the structure of each side is as follows: one end (front end) of the base link 91 is pivotally connected to the top of the vertical rod 13 of the base 10 through a first pivot 92, and the other end (rear end) is slidably pivoted. Inserted into the preset elongated guide groove 39 on the side of the main frame 31 of the treadmill 20 , it can slide along the long axis of the main frame 31 . One end of the support link 93 is coaxially pivoted to the aforementioned rear end of the base link 91, so that the two can slide synchronously within the range of the elongated guide groove 39 while the other end passes through the notch of the link. 65 penetrates into the support rod 61 (as shown in FIG. 1 ), and is pivotally connected to an appropriate position on the support rod 61 through a second pivot 94 . The drive rod 95 extends longitudinally and is completely contained in the hollow interior of the support rod 61 , its bottom end is pivotally connected to the position of the support link 93 close to the second pivot 94 , and its top end is pivotally connected to the inner end of the side armrest 71 . Each instrument connecting rod 97 protrudes radially outward from the end of the instrument shaft 81 and is located in the hollow interior of the support rod 61 . One end of each armrest link 96 is pivotally connected to the outer end of the instrument link 97, and the other end goes down through the armrest notch 64 and is pivotally connected to the side armrest 71, which is closer to the outer end of the armrest than the armrest pivot 72. . The actual function and action principle of the linkage mechanism 90 will be described in detail later.

The above is the main structure of the treadmill 1 provided by a preferred embodiment of the present invention. When the treadmill 1 is in the state of use shown in FIGS. to adjust the difficulty of exercise.

As shown in Figure 3, when the treadmill 20 is in the use position, the rear end of the support link 93 of the linkage mechanism 90 is locked at the front end of the elongated chute 39 of the treadmill 20 along with the rear end of the base link 91, Based on the oblique support and restriction of the support link 93, each support rod 61 of the support rod group 60 appears to extend from the front end of the treadmill 20 upwards and slightly backwards at the same time, and is positioned at the use angle as shown in the figure (note: when the treadmill 20. When the inclination changes, the angle of the support rod 61 relative to the ground G will also change slightly. This angle change is in line with ergonomic design, and the change range belongs to the aforementioned "use angle"). And, as shown in Fig. 4 and Fig. 5 again, armrest group 70 and instrument group 80 also can be subjected to the limitation of interlocking mechanism 90 and be positioned at respective use angles, that is, each side armrest 72 is from support bar 61 top end to Rear extension, for the user to hold when exercising; the main body of the instrument 82 is extended forward and upward by the instrument shaft 81, so that the instrument interface 83 on the panel is convenient for the user to view and operate, and at the same time, the middle armrest 73 is presented by the instrument shaft 81 extends backward and downward for the user to selectively grasp when exercising.

When the treadmill 1 is not in use, the user can choose to fold it into the folded state shown in FIGS. 7 to 9 . In this embodiment, before folding, if the running platform 20 presents a slope shape, the user must first lower its slope back to the lowest state as shown in Figure 3, that is, to make the main frame 31 and the auxiliary frame 21 are roughly parallel to the ground G (note: if it is designed to be electrically folded, this action can be automatically completed by the preset program), and then, the user exerts force to lift the rear end of the treadmill 20 upwards so that it can be assisted by the front end. The frame pivot 24 rotates relative to the base 10 as the axis, and reaches the folded position as shown in FIG. 7 with the assistance of the auxiliary device 50 (gas spring).

As shown in Fig. 3, Fig. 6 and Fig. 7, when the treadmill 20 rotates from the use position to the folded position, the position of the support rod pivot 62 at the bottom end of the support rod set 60 will also follow the position of the treadmill 20 (with Auxiliary frame pivot 24 is axle center) upwards and forward rotation. Simultaneously, the rear end of the base connecting rod 91 can be driven by the treadmill 20, while sliding along the elongated guide groove 39 of the treadmill 20, while turning upwards along with the treadmill 20 (counterclockwise rotation in the left view) . Because the rear end of support link 93 is coaxially pivoted with the rear end of base link 91, therefore support link 93 also can be forced to rotate and shift, and with its front end (the first that is pivotally connected on the support bar 61) Two pivots 94) push the support rod 61 forward until the support rod 61 reaches the folding angle as shown in FIG.

Simultaneously, during the folding process of the treadmill 20, the rear end of the support link 93 will be displaced from the original lower position to the second pivot 94 higher than the front end, thereby pushing up the driving rod 95 inside the support rod 61. top, so that the driving rod 95 drives the inner end of the side armrest 71 with its top, and rotates upwards and backwards with the armrest pivot 72 as the axis (clockwise in the left view), that is, the outer side of the side armrest 71 The end is turned downwards and forwards until it swings into the hollow interior of the support rod 61 through the notch 64 of the armrest, presenting a longitudinally extending form (folding angle) as shown in FIG. 7 .

As shown in Figure 4 and Figure 5, when the side armrest 71 is rotated from the use angle to the folded angle, the instrument link 97 and the instrument shaft 81 will be driven to rotate through the armrest link 96, so that the instrument main body 82 and the middle armrest 73 Rotate together to an angle substantially parallel to the long axis of the support rod 61 and between the front and rear widths of the support rod 61 , as shown in FIG. 7 and FIG. 9 .

In this embodiment, when the treadmill 1 is in the retracted state, the elongated elastic force of the left and right auxiliary devices 50 (gas springs) can push the treadmill 20 to its retracted position, and then sufficient torque must be applied. And it is possible to overturn the running platform 20 only when exceeding a certain angle, which is basically safe and secure. Of course, the present invention can further add a locking device (not shown) between the treadmill and the base, between the treadmill and the support bar group, or between the treadmill and the wall, so that the treadmill 1 can be more firmly remain in the collapsed state.

It can be seen from the above description and the accompanying drawings that the treadmill of the present invention is in an upright flat shape in a folded state, and its front and rear widths are extremely small (for example, in the above-mentioned embodiments, all components do not exceed the rear of the base 10 after being folded). Edge), so the space volume and floor area can be reduced to the minimum, and it will hardly affect the general indoor activities. If it is designed in a form that can be moved and laid after being folded, it can be conveniently stored in a narrow vertical space or a horizontal flat space.

Moreover, in the form of manual folding, the user can fold the treadmill from the use state to the folded state, or open it from the folded state to the use state (the action principle is the same as above), which is very time-saving. convenient. Relatively, if the present invention is designed to be electrically retractable (for example, the auxiliary device 50 is replaced by a motor-driven screw-coil set), through the effectiveness of the above-mentioned structure of the present invention, the treadmill only needs to be provided with a set of driving The device can make all movable components change between the use state and the folded state, and the cost is low.

The above detailed description only discloses a preferred embodiment of the present invention, but when the present invention is implemented, on the basis of the above-mentioned embodiments of the present invention, some structures can be changed or replaced irrelevantly, for example: linkage mechanism Various combinations of levers and/or linkages may be used to achieve the aforementioned effects; the treadmill is directly pivoted on the base with a single frame; the set of support rods extends upward from the base, or remains fixed and perpendicular to the ground; The side armrests extend upwards from the support rods in the folded state and the like.
