Description

Technical Field

[0001] The utility model relates to the technical field of training equipment, in particular to a new waist and leg exerciser. Background Art

[0002] Waist and leg exercisers are common exercise equipment for daily physical exercise or rehabilitation training. The application document previously applied by the applicant with application number CN202010230755.6 discloses a four-limb coordinated treadmill. Trainees can achieve the purpose of exercise by simulating the movements of ungulates such as cats walking or jogging on all fours.

[0003] However, since the device requires coordinated movements of the limbs when in use, the trainee must coordinate the movements of the limbs through the torso, especially the waist and back, to complete the entire set of training movements. This means that the device is only suitable for healthy people. For patients with spinal diseases (such as cervical spondylosis, spondylosis and lumbar spondylosis), the training difficulty will be greatly increased, and sometimes even cause secondary damage to the patient's spine.

[0004] The patent document with application number CN202311746296.7 previously applied by the applicant also discloses a horizontal waist and leg exerciser. When used by some patients with mild spinal diseases, this waist and leg exerciser can have a good exercise effect in short-term training. However, due to the two hind limb modules used to support the lower limbs, the calves move back and forth in a state parallel to the ground when in use, making it difficult for trainees to use the strength of the lower limbs to drive the movement of the hind limb modules. Long-term use of the legs is more likely to cause discomfort. Moreover, since the upper limb support module is a fixed structure, when used by trainees with more serious spinal diseases, the waist or back will be excessively compressed, and even have a reverse exercise effect. Utility Model Content

The stop part, the supporting part and the placement part together form a "√" shape. The trainee can kneel at the supporting part and cooperate with the thigh through the stop part and with the calf through the placement part to complete the forward and backward driving action of the lower limb support device.

[0010] In order to enable the lower limbs of the trainee to better cooperate with the knee support, a first groove is provided in the middle part of the upper side of the knee support along the front-to-back direction.

[0011] In the novel waist and leg exerciser as described above, the upper limb support system also includes an angle limiting device capable of limiting the rotation angle of the upper limb support device, so that the trainee can more easily perform swinging movements with the upper body in coordination with the lower limb training.

[0012] As described above, a new type of waist and leg exerciser, the first bracket includes support rods on both sides, and the lower limb support device also includes a sliding seat slidably arranged on the support rod. In order to make the sliding seat slide back and forth along the support rod more labor-saving, the sliding seat is arranged to include a slide frame, and the slide frame rolls with the support rod through rollers arranged thereon and located on the upper and lower sides of the support rod.

[0013] In order to ensure the stability of the slide seat sliding along the support rod, at least two rollers are provided on the slide frame, which are located on the upper side and / or the lower side of the support rod.

[0014] In order to ensure the waist and leg training effect of the novel waist and leg trainer as described above, the first bracket is also provided with a damping device which is transmission-connected with the two lower limb supporting devices.

[0015] As a preferred embodiment, the damping device includes a damping rope that is transmission-connected to the two lower limb supporting devices, and an adjustable damper that can provide resistance for the damping rope, and the adjustable damper can provide adjustable movement resistance for the lower limb supporting device, thereby improving the applicability of the waist and leg exerciser;

[0016] As a further preference, in order to be able to more conveniently adjust the size of the movement resistance according to the user experience, the adjustable damper is arranged on the front side of the first bracket.

[0018] In order to further ensure the coordination effect between the upper limb and the elbow rest, a second groove is provided in the middle of the elbow rest.

[0019] The beneficial effects of the present invention are as follows: the present invention is a new type of waist and leg exerciser, which can support the knees of the trainee through the knee support, and enable the trainee to drive the lower limb support device to slide forward and backward with the help of the power of the knee, and in the process of the lower limbs moving forward and backward, the upper body swings left and right, thereby reducing excessive pressure on the waist or back, so that the waist can also have a corresponding exercise effect in the process of the lower limbs moving forward and backward, and finally ensure that the whole set of training movements can be completed smoothly; and the side view shape of the knee support is "√"-shaped, which makes the driving of the lower limb support device more labor-saving and increases the training experience.

[0046] Specifically, the damping device 13 also includes a fixed pulley 131 arranged on the inner side of the two support frames 111 on the first bracket 11. The fixed pulley 131 is provided with two and is respectively arranged close to the two support rods 112. The damping rope 132 is arranged around the four fixed pulleys 131 in sequence. In order to be able to more conveniently adjust the size of the moving resistance according to the user experience, the adjustable damper 133 is arranged on the front side of the first bracket 11. Specifically, a front cover plate 113 and a rear cover plate 114 are respectively arranged on the inner side of the support frames 111 located on the front and rear sides of the first bracket 11. The adjustable damper 133 is arranged on the front cover plate 113, and the damping rope 132 is arranged around the adjustable damper 133.

[0047] In order to facilitate the adjustment of the tension of the damping rope 132, Figure 6 The damping rope 132 includes two rope sections 1321, and the two ends of each rope section 1321 are respectively provided with a first joint 1322 and a second joint 1323. The front and rear sides of the roller 1212 located at the lower side of the support rod 112 inside the slide 1211 are provided with a clamping plate 1213, and the lower side of the clamping plate 1213 is provided with a clamping interface; taking the clamping plates 1213 located at the front and rear sides of the roller 1212 as an example, the first clamping plate and the second clamping plate are respectively provided, wherein a rope section 1321 is arranged around the two fixed pulleys 131 and the adjustable damper 133 located at the front side of the first bracket 11, and the first joint 1322 thereon is directly connected to one of the lower limb supports The first clamping plate on the support device 12 is clamped and connected, the second joint 1323 passes through the first clamping plate on the other lower limb support device 12 and is provided with an adjusting nut (not shown in the figure), and the other section of the rope 1321 passes around the two fixed pulleys 131 located on the rear side of the first bracket 11, and the first joint 1322 thereon is directly clamped and connected with the second clamping plate on one of the lower limb support devices 12, and the second joint 1323 passes through the second clamping plate on the other lower limb support device 12 and is provided with an adjusting nut (not shown in the figure). The damping tension force can be adjusted through the second joints 1323 on the two sections of the rope 1321 to ensure that the waist and leg exerciser can be used normally.

[0048] In this embodiment, combined with Figure 7 The upper limb support system 2 includes a second bracket 21, on which an upper limb support device 22 is provided, and the trainee can lie on the upper limb support device 22 to complete waist and leg training.

[0049] In order to increase the applicability of the waist and leg exerciser, the distance between the second bracket 21 and the first bracket 11 is adjustable. Specifically, the second bracket 21 also includes a support frame 111. The rear side of the support frame 111 is provided with a plug 211 pointing to the first bracket 11. The support frame 111 on the front side of the first bracket 11 is provided with a first sleeve 115 pointing to the second bracket 21 and cooperating with the plug 211. The first sleeve 115 is also provided with a tightening piece. The distance between the two brackets can be adjusted by cooperating between the plug 211 and the first sleeve 115.

[0050] As another core technical concept of the present invention, the upper limb support device 22 is configured to be able to rotate around a vertical axis. Through this configuration, the trainee can swing the upper body left and right while the lower limbs move forward and backward, thereby reducing excessive pressure on the waist or back, and allowing the waist to have a corresponding exercise effect during the movement of the lower limbs forward and backward, ultimately ensuring that the entire set of training movements can be completed smoothly.

[0051] Specifically, a second sleeve 212 is vertically provided on the upper side of the front end of the insertion tube 211 (one end close to the upper support frame 111 of the second bracket 21), and the upper limb support device 22 includes a vertically arranged telescopic rod 221, and an upper limb support unit 222 at the upper end of the telescopic rod 221, and the lower end of the telescopic rod 221 is arranged in the second sleeve 212. The setting of the telescopic rod 221 enables the trainee to adjust the height of the upper limb support unit 222 according to his body height, thereby further ensuring the applicability of the waist and leg exerciser.

[0052] As for the structure of the upper limb support unit 222, it includes a bracket arranged at the upper end of the telescopic rod 221. The bracket is a rod-shaped structure, the middle part of which is connected to the upper end of the telescopic rod 221, and the two ends are bent backwards, and elbow rests that can support the elbows are provided on both sides of the upper part of the bent part, so that the torso of the trainee can be pressed more stably on the upper limb support unit 222 through the upper limbs.

[0053] In order to further ensure the coordination effect between the upper limb and the elbow rest, a second groove is provided in the middle part of the upper side of the elbow rest along the front-to-back direction.

[0056] As a preferred embodiment, Figure 8 The upper limb support system 2 also includes an angle limiting device 23 that can limit the rotation angle of the upper limb support device 22, so that the trainee can be more relaxed when performing swinging movements with the upper body in coordination with the lower limb training.

[0057] Specifically, the lower end of the second sleeve 212 extends to the lower side of the insertion tube 211, the telescopic rod 221 is inserted into the second sleeve 212, and the lower end extends out of the lower end of the second sleeve 212, the lower outer ring of the telescopic rod 221 is close to the lower end of the second sleeve 212, and a bearing is provided between the second sleeve 212, and the bearing is fixed to the telescopic rod 221, the rotation angle limiting device 23 includes a fixing nut 231 arranged at the lower end of the second sleeve 212, the fixing nut 231 is spirally connected to the lower end of the second sleeve 212, and the lower inner ring is in an inward shape, the lower side of the bearing is pressed against the upper side of the inward part of the fixing nut 231, so that the fixing nut 231 is used as the axis. The bearing provides a supporting effect, and then provides a supporting effect for the telescopic rod 221, so that the telescopic rod 221 can and can only rotate relative to the second sleeve 212 without axial relative sliding. The angle limiting device 23 also includes a rotating block 232 arranged at the lower end of the telescopic rod 221 and capable of rotating with the telescopic rod 221, and one side of the rotating block 232 protrudes; the angle limiting device 23 also includes an n-shaped stopper 233 arranged at the lower side of the insertion tube 211 and with an opening facing downward, and the protruding part of the rotating block 232 is located in the stopper 233. This arrangement is used to limit the rotation of the rotating block 232, and then limit the rotation of the telescopic rod 221, thereby ultimately achieving the effect of limiting the rotation angle of the upper limb support device 22.
