Description

Technical Field

[0001] This invention relates to the field of sports training equipment technology, specifically a supine waist and leg exercise device. Background Technology

[0002] Sports exercise equipment, such as rowing machines, fitness machines, step bikes, and treadmills, are commonly used in people's daily physical exercise. Treadmills, in particular, usually require people to stand on them to complete simulated running training. However, this training method requires people to stand on them (with their spine vertical) to complete the training, but upright exercise also puts an extraordinary load on the trainee's spine (especially the lumbar spine).

[0003] Based on the aforementioned deficiencies, the applicant previously filed an application with application number CN202010230755.6, which disclosed a four-limb coordinated treadmill. This treadmill uses a forelimb module and a hindlimb module, along with a transmission system, to enable trainees to simulate the walking or jogging movements of ungulates such as felines in a prone position, thereby achieving a training effect. However, in practical applications, it has been found that the use of the aforementioned four-limb coordinated treadmill still has some limitations.

[0004] The aforementioned four-limb coordinated treadmill employs a transmission system that allows the movement of the forelimb or hindlimb modules to be transmitted to the hindlimb or forelimb modules, ultimately producing a coordinated limb movement effect. This serves as a simulation training method, aiming to exercise the muscles surrounding the spine and stabilize the lumbar vertebrae. However, because the device involves the coordinated movement of the forelimb and hindlimb modules, trainees must coordinate the movements of their limbs through their torso to maintain stability during training. This undoubtedly increases the training difficulty for patients with spinal diseases (such as cervical spondylosis, spinal spondylosis, and lumbar spondylosis).

[0005] On the other hand, its forelimb module adopts a palm support plate design. When training, the upper limbs are vertically supported on the palm support plate to ensure that the device can smoothly simulate the posture of an animal walking or jogging on all fours, so as to achieve the training effect. However, for trainees with lumbar spine diseases, this training posture is also quite burdensome. Summary of the Invention

[0006] To address the technical problems existing in the background art, the present invention provides a supine waist and leg exercise device.

[0007] The technical solution of this invention is as follows:

[0008] A supine waist and leg exercise device includes a waist and leg exercise device and a trunk support device on its front side. The trainee can lie prone on the trunk support device and complete waist and leg exercises through waist and leg exercises.

[0009] Specifically, the waist and leg exercise device includes a horizontally arranged first support frame, on both sides of which are lower limb support modules that can slide back and forth via guide modules. The waist and leg exercise device also includes a damping module disposed on the first support frame. The lower limb support modules are convexly connected to the damping module. The damping module is configured to provide sliding resistance to the lower limb support modules and to restrict the two lower limb support modules to slide only in opposite directions. The lower limb support module includes a first support plate that is slidably connected to the guide module and convexly connected to the damping module. The rear side of the first support plate is provided with a foot pedal frame, and the upper front side is provided with a knee rest. The torso support device includes a second support frame connected to the front side of the first support frame. The upper limb support module is flexibly mounted on the upper side of the first support frame. The upper limb support module includes a second support plate, and the upper sides are provided with elbow rests.

[0010] The aforementioned supine waist and leg exerciser allows users to pre-adjust the height of the upper limb support module according to their own height, place their elbows on the elbow rests, kneel on the knee rests, and place their feet on the foot pedals. This allows the user to lie prone on the upper limb support module while maintaining a horizontal spine. The combined action of the feet and knees drives the two guide modules to reciprocate, effectively exercising the legs and waist. On one hand, it reduces the pressure on the spine (especially the lumbar vertebrae) during upright exercise, thus achieving a positive exercise effect. On the other hand, this method of using the upper limb support module to support the torso allows the exercise to rely solely on the reciprocating motion of the lower limbs and the coordinated twisting of the waist, avoiding the involvement of the torso (or upper limbs) in the waist and leg exercise. This makes the exerciser (the aforementioned supine waist and leg exerciser) suitable for the daily exercise of patients with spinal diseases. The damping module increases the resistance of the exercise, meeting the requirements of the trainee's progressive training.

[0011] As described above, in a preferred embodiment of the supine waist and leg exercise device, the distance between the first support frame and the second support frame is adjustable, thereby adjusting the distance between the upper limb support module and the lower limb support module, so that the exercise device can be suitable for trainees of different heights.

[0012] In a preferred embodiment, the second support plate is provided with handles on both sides in front of the elbow supports, so that when the trainee supports his elbows on the elbow supports, he can grip the handles with both hands to ensure the stability of the torso support.

[0013] As described above, the supine waist and leg exercise device includes a damping module that is rotatably located in the middle of the first support frame and has rotational resistance. The damping module also includes a transmission rope that is in the form of a closed loop and passes around the damping plate. Both lower limb support modules are connected to the transmission rope, and the movement of one lower limb support module can drive the other lower limb support module to move in the opposite direction via the transmission rope.

[0014] Specifically, the damping module further includes a first roller and a second roller located front to back on one side of the first support frame, and a third roller and a fourth roller located front to back on the other side of the first support frame. The damping disc is located between the four rollers. The transmission rope is arranged around the outside of the four rollers, and the transmission rope between the first roller and the third roller is arranged around the damping disc on the side away from the first roller and the third roller, or the transmission rope between the second roller and the fourth roller is arranged around the damping disc on the side away from the second roller and the fourth roller. The first support plates of the lower limb support modules on both sides are respectively connected to the transmission rope between the first roller and the second roller, and the transmission rope between the third roller and the fourth roller. The damping disc can provide rotational resistance to the transmission rope, thereby providing sliding resistance to the sliding of the lower limb support module, and restricting the two lower limb modules to slide in opposite directions only.

[0015] In a preferred embodiment, the rotational resistance of the damping disc is adjustable, allowing trainees to adjust the rotational resistance of the damping disc according to their own training needs to achieve better training results, thus further expanding the applicability of the exercise equipment.

[0016] In the supine waist and leg exercise device described above, in order to ensure that the lower limb support module can have a better support effect and can ensure its own smooth sliding, the lower side of the first support plate slides with the upper side of the first support frame through support wheels.

[0017] To further ensure the stability of the lower limb support module and prevent left-right swaying, at least two support wheels are provided on the lower sides of the first support plate.

[0018] As described above, in order to make the upper limb support module provide more comfortable and stable support for the trainee, the upper end of the elbow rest has an elongated oval structure. This allows the trainee to place their forearm entirely on the elbow rest when holding the handle, thereby enabling the trainee's torso to be more stably pressed on the forearm and smoothly complete the waist and leg exercise.

[0019] To further improve exercise comfort, the elbow supports are designed in a figure-eight shape with the openings facing backward.

[0020] As described above, in order to enable the knee to better cooperate with the foot to drive the movement of the lower limb support module and achieve the exercise effect, the upper part of the knee support is provided with a knee placement groove that runs through its rear side.

[0021] To further ensure comfort during exercise and improve the exercise experience, the knee support and elbow support are made of silicone, rubber, or a leather-covered sponge structure.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention is a supine waist and leg exercise device. When using it for waist and leg exercises, the trainee can adjust the height of the upper limb support module according to their own height, then place the elbow on the elbow rest, and finally kneel on the knee rest and place the feet on the foot pedal frame. This allows the trainee to lie prone on the upper limb support module with the spine horizontal, and alternately kick the legs to drive the two guide modules to move back and forth, which can exercise the legs and waist. It reduces the pressure on the spine (especially the lumbar spine) caused by upright exercise, thus achieving a positive exercise effect.

[0024] This invention is a supine waist and leg exercise device. By using an upper limb support module to complete the trunk support work, the exercise relies solely on the reciprocating movement of the lower limbs and the coordinated twisting of the waist to achieve waist and leg exercise. This avoids the trunk (or upper limbs) directly participating in waist and leg exercise, making the exercise device suitable for the daily exercise of patients with spinal diseases, and also allowing exercisers to exercise for a longer period of time.

[0025] The present invention is a supine waist and leg exercise device. The setting of its damping module increases the resistance of the exercise and meets the requirements of the trainee to gradually advance the training. Attached Figure Description

Detailed Implementation

[0040] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0041] Example

[0042] This embodiment provides a supine waist and leg exercise device, see [link / reference] Figures 1-3The device includes a waist and leg exercise device 1 and a trunk support device 2 on its front side. Trainees can lie prone on the trunk support device 2 with their spine horizontal to complete waist and leg exercises. The structure of the exercise device (the above-mentioned supine waist and leg exercise device) will be described in detail below.

[0043] In this embodiment, combined with Figure 4 The waist and leg exercise device 1 includes a horizontally arranged first support frame 11, with lower limb support modules 13 that can slide back and forth on both sides via guide modules 12. Trainees can lie prone on the torso support device 2 and place their two lower limbs on the two lower limb support modules 13 respectively, and use their lower limbs to drive the two lower limb support modules 13 to slide back and forth to complete the waist and leg exercise.

[0044] Specifically, combining Figure 5 The first support frame includes a horizontally arranged frame structure 111, and the guide module 12 includes two guide seats 121 arranged opposite each other, with a sliding rod 122 horizontally arranged between the two guide seats 121. Figure 8 The lower limb support module 13 includes a first support plate 131 horizontally arranged on the upper side of the slide bar 122, with a slider 134 on its lower side. The slider 134 slides with the slide bar 122 and is slidably connected to the guide rod of the guide module 12, thereby enabling forward and backward sliding movements. The rear side of the first support plate 131 is provided with a foot pedal frame 133, and the upper front side is provided with a knee support 132. When the trainee is performing waist and leg exercises, he can lie prone on the torso support device 2, kneel on the knee support 132, and place his feet on the foot pedal frame 133. Through the cooperation of the knees and feet, the lower limb support module 13 is driven to slide forward and backward, thereby achieving waist and leg exercises.

[0045] In order to enable the knee to better cooperate with the foot to drive the movement of the lower limb support module 13 and achieve the exercise effect, the upper part of the knee support 132 is provided with a knee placement groove that runs through its rear side, so that the knee can be placed in the knee groove.

[0046] To ensure comfort during exercise and improve the exercise experience, the knee support 132 is made of silicone, rubber, or a leather-covered sponge structure.

[0047] In a preferred embodiment, to ensure that the lower limb support module 13 has a better support effect and can ensure its smooth sliding, the slider 134 is located in the middle of the lower front end of the first support plate 131, and the lower rear end of the first support plate 131 slides with the upper side of the first support frame 11 through the support wheel 135.

[0048] As a further preferred embodiment, in order to further ensure the stability of the lower limb support module 13 and prevent it from swaying left and right, at least two support wheels 135 are provided on the lower sides of the first support plate 131.

[0049] In this embodiment, to prevent the lower limb support module 13 from sliding freely without restriction, and to further ensure that the lower limb support module 13 can achieve a good waist and leg exercise effect, combined with... Figure 6 and Figure 7 The waist and leg exercise device 1 also includes a damping module 14 disposed on the first support frame 11. The first support plate 131 of the lower limb support module 13 is connected to the damping module 14 in a transmission manner. The damping module 14 is configured to provide sliding resistance to the lower limb support module 13.

[0050] Furthermore, the damping module 14 includes a damping disc 141 rotatably disposed in the middle of the first support frame 11 and having rotational resistance; the damping module 14 also includes a transmission rope 146 in a closed loop shape that passes around the damping disc 141; both lower limb support modules 13 on both sides are connected to the transmission rope 146, and the movement of one lower limb support module 13 can drive the other lower limb support module 13 to move in the opposite direction through the transmission rope 146.

[0051] Specifically, regarding the structure and arrangement of the damping module 14, it further includes a first roller 142 and a second roller 143 located front-to-back on one side inside the first support frame 11, and a third roller 144 and a fourth roller 145 located front-to-back on the other side inside the first support frame 11. The four rollers form a rectangular structure, and the damping disk 141 is located between the four rollers and inside the rectangular shape formed by the four rollers. The transmission rope 146 is arranged around the outside of the four rollers, and the transmission rope 146 between the second roller 143 and the fourth roller 145 is arranged around the damping disk 141 on the side away from the second roller 143 and the fourth roller 145. Of course, this can also be... The transmission rope 146 between the first roller 142 and the third roller 144 is arranged around the damping disc 141 on the side away from the first roller 142 and the third roller 144, without any additional restrictions. The inner side of the first support plate 131 of the lower limb support modules 13 on both sides is provided with an intermediate connector 136, which is connected to the transmission rope 146 between the first roller 142 and the second roller 143, and the transmission rope 146 between the third roller 144 and the fourth roller 145, respectively, through the first connector. The damping disc 141 can provide rotational resistance to the transmission rope 146, thereby providing sliding resistance to the sliding of the lower limb support module 13, and restricting the two lower limb modules to slide in opposite directions only.

[0052] In a preferred embodiment, the rotational resistance of the damping disc 141 is adjustable. For example, the damping disc 141 can be a disc-shaped adjustable-gear magnetic damper, so that trainees can adjust the rotational resistance of the damping disc 141 according to their own training needs to achieve better training results, further expanding the applicability of the exercise device.

[0053] Specifically, regarding the structure of the damping disc 141, this embodiment also provides one implementation method. In this embodiment, the damping disc 141 includes a main disc body rotatably mounted on the frame 111, a transmission rope 146 passing around the main disc body, and an adjustment frame located above it and fixedly connected to the frame 111. An iron ring is provided on the upper outer ring of the main disc body, and a plurality of magnetic attracting elements cooperating with the iron ring are provided circumferentially on the adjustment frame. The magnetic attracting element includes a sliding column vertically slidably mounted on the adjustment frame, with a magnet on its lower side and a button on its upper side. A positioning column is also provided on the adjustment frame at the position where the sliding column is located. The sliding column has two positioning grooves at the positions corresponding to the positioning columns. By pressing the button, the magnet can be moved down by the sliding column and attracted to the iron ring. The sliding column is locked by the elastic cooperation between the positioning column and the lower positioning groove. At this time, the magnet can provide an attractive frictional resistance to the iron ring. By controlling the cooperation between different numbers of magnetic attracting elements and the iron ring, the magnitude of the magnetic resistance can be adjusted.

[0054] Based on the above structure, the upper side of the frame 111 is also provided with a cover plate to provide necessary protection for waist and leg exercises.

[0055] Meanwhile, to ensure the stability and balance of the frame 111, height-adjustable feet 15 are provided on the lower side of the frame 111.

[0056] In this embodiment, combined with Figure 9 The torso support device 2 includes a second support frame 21 connected to the front side of the first support frame 11, and an upper limb support module 22 is provided on its upper side. Trainees can lie on the upper limb support module 22 to complete waist and leg exercises through the waist and leg exercise device 1.

[0057] In a preferred embodiment, the distance between the first support frame 11 and the second support frame 21 is adjustable, thereby adjusting the horizontal distance between the upper limb support module 22 and the lower limb support module 13, so that the exerciser can be suitable for trainees of different heights.

[0058] Specifically, the cover plate includes a first cover plate 112 located on the upper rear side of the frame 111 and a second cover plate 113 located on the upper front side of the frame 111. A first insert 114 located below the second cover plate 113 is horizontally provided at the front end of the frame 111. The second support frame 21 includes a horizontally arranged first support rod 211, one end of which is inserted into the first insert 114, and the other end is connected to a vertically arranged second insert 212. A support 213 is provided on the lower side of the second insert 212. A first fastener 115 is also provided on the first insert 114. The first fastener 115 can restrict the relative movement between the first support rod 211 and the first insert 114, and the depth of the first support rod 211 inserted into the first insert 114 can be adjusted by loosening the first fastener 115, thereby completing the adjustment of the actual distance between the first support frame 11 and the second support frame 21.

[0059] To ensure the stable cooperation between the first support frame 11 and the second support frame 21, the lower side of the support 213 is also provided with an adjustable foot 15 that can adjust the support height.

[0060] Preferably, the upper limb support module 22 is height-adjustable so that when the trainee lies prone on the upper limb support module 22, the spine can be in a horizontal position when its height is adjusted.

[0061] Specifically, the upper limb support module 22 includes a second support rod 221 that is vertically arranged and whose lower end is inserted into the second insert 212. The upper end of the second support rod 221 is provided with a second support plate 222. Elbow supports 223 are provided on the upper parts of both sides of the second support plate 222, and handles 224 are provided on the front side of the two elbow supports 223. The second insert 212 is also provided with a second fastener 214. The second fastener 214 can restrict the relative movement between the second support rod 221 and the second insert 212, and the depth of the second support rod 221 inserted into the second insert 212 can be adjusted by loosening the second fastener 214, thereby adjusting the support height of the upper limb support module 22.

[0062] Based on the above structure, when using the exerciser for waist and leg exercises, trainees can adjust the height of the upper limb support module 22 according to their own height, then grip the handle 224 and place their elbows on the elbow rest 223, finally kneel on the knee rest 132 and place their feet on the foot pedal 133. Ultimately, the trainee can lie prone on the upper limb support module 22, keeping their spine horizontal, and through the combined action of their feet and knees, drive the two guide modules 12 to reciprocate, achieving the effect of exercising the legs and waist. This reduces the pressure on the spine (especially the lumbar spine) during upright exercise, thus achieving a positive exercise effect. At the same time, this method of completing the trunk support work through the upper limb support module 22 allows the training to rely solely on the reciprocating movement of the lower limbs and the coordinated twisting of the waist to achieve waist and leg exercises, avoiding the involvement of the trunk (or upper limbs) in waist and leg exercises. This makes the exerciser suitable for the daily exercise work of patients with spinal diseases, and allows the trainee to exercise for a longer period of time.

[0063] Based on the above structure, in order to make the upper limb support module 22 support the trainee more comfortably and stably, the elbow support 223 is designed with an elongated oval structure on the upper end, so that when the trainee holds the handle 224, the forearm can be placed on the elbow support 223 as a whole, thereby allowing the trainee's torso to be pressed more stably on the forearm, completing the torso support work, and finally successfully completing the waist and leg exercise work.

[0064] To meet the needs of trainees and improve exercise comfort, the elbow supports 223 are designed with an opening facing backward in a figure-eight shape.

[0065] To further ensure comfort during exercise and improve the exercise experience, the elbow support 223 is made of silicone, rubber, or a leather-covered sponge structure.

[0066] To enhance the exercise experience, the front side of the second support plate 222 is also equipped with a mobile device holder 225 for placing mobile phones or tablets.
