Description

Technical Field

[0001] The present invention particularly relates to a shoulder training device with correction function. Background Art

[0002] Hemiplegia is a severe functional disorder caused by damage to the central nervous system. According to statistics from the World Health Organization, a large number of new hemiplegic patients are diagnosed annually worldwide, and this number is expected to continue to rise due to the accelerated aging of the population and changes in lifestyle. Hemiplegic patients place a heavy financial burden and caregiving pressure on their families.

[0003] Hemiplegic patients have an imbalance in muscle strength around the shoulder joint, especially the supraspinatus and deltoid muscles that maintain the stability of the shoulder joint, which become flaccid and paralyzed due to nerve damage, resulting in changes in the normal anatomical relationship between the glenoid cavity and the humeral head. This dysfunction seriously hinders the recovery of upper limb function in hemiplegic patients. Therefore, shoulder muscle and joint exercises are needed to improve their recovery efficiency.

[0004] For example, Chinese invention patent publication number CN102698410B provides a head, neck, and shoulder muscle rehabilitation exerciser. This exerciser effectively strengthens the superficial and deep muscles of the head and neck, restores muscle balance in the head, neck, and surrounding cervical spine, relieves pressure within the cervical intervertebral discs, and restores the normal physiological curvature of the cervical spine. It also effectively exercises the pectoralis major, latissimus dorsi, and biceps brachii of the upper limbs, to a certain extent curbing and slowing the trend of cervical degeneration and reducing the incidence of cervical spondylosis.

[0005] However, most hemiplegic patients have impaired motor function of one side of their limbs. When using traditional exercisers for exercise, most existing shoulder exercise devices do not have the function of correcting the back. As a result, hemiplegic patients are prone to back spine deformation after exercising in incorrect postures for a long time. In view of this, a shoulder exercise device with a correction function is proposed to solve the above technical problems. Summary of the Invention

[0053] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0054] Example:

[0055] like Figures 1 to 3 As shown, the present invention provides a shoulder exercise device with a corrective function, comprising a support plate 1, a mounting frame 12 disposed on one side of the support plate 1, and multiple sets of L-shaped plates 14 disposed on one side of the mounting frame 12. Multiple sets of threaded knobs 15 are screwed onto the L-shaped plates 14. During use, the device can be placed on a seat, with the multiple sets of L-shaped plates 14 snapped onto the seat back, and the device can be fixed by turning the threaded knobs 15. A flexible pad 13 is disposed between the mounting frame 12 and the support plate 1, and a flexible cloth 11 is disposed on the support plate 1, with the flexible pad 13 abutting against the flexible cloth 11. After installation, the patient can rest on the support plate 1, which is arranged in an arc shape to fit the patient's back curve, and then perform shoulder exercises.

[0056] like Figures 2 to 5As shown, in this embodiment, an exercise unit is provided on both sides of the mounting frame 12. The exercise unit includes a mounting cylinder 2 rotatably provided on the support plate 1. A connecting arm 22 is hingedly connected to the mounting cylinder 2, and a strap 23 is provided at the end of the connecting arm 22. A correction seat 3 is slidably provided on the mounting frame 12 in a direction perpendicular to the support plate 1. A propulsion mechanism connected to the correction seat 3 is provided on the mounting cylinder 2. The propulsion mechanism converts the rotation of the mounting cylinder 2 into a driving force for the correction seat 3 to slide. The propulsion mechanism includes a propulsion seat 35 slidably provided on the mounting frame 12. The mounting cylinder 2 is provided with a transmission assembly connected to the propulsion seat 35. The transmission assembly converts the rotation of the mounting cylinder 2 into a driving force for the propulsion seat 35 to slide. The transmission assembly includes a first gear 21 provided on the mounting cylinder 2. The propulsion seat 35 is provided with a rack 34 meshing with the first gear 21.

[0057] After the device is fixed, the patient can connect his hands to the two sets of connecting arms 22 through two sets of straps 23 respectively, and the patient can do horizontal chest expansion exercises or longitudinal arm swinging exercises. During the horizontal chest expansion exercise, the mounting cylinder 2 can be driven to rotate on the push plate 1. During the rotation process, the mounting cylinder 2 can drive the propulsion seat 35 to slide on the mounting frame 12 through the cooperation of the first gear 21 and the rack 34.

[0058] like Figure 4 、 5 As shown in Figures 6 and 7, in this embodiment, the propulsion mechanism further includes a propulsion assembly disposed on the propulsion seat 35 and connected to the correction seat 3. The propulsion assembly converts the sliding movement of the propulsion seat 35 into a sliding movement of the correction seat 3. The propulsion assembly includes a positioning post 32 disposed on the correction seat 3. The positioning post 32 is slidably mounted on the mounting frame 12 along its axis. A first drive shaft 33 is disposed on the positioning post 32. The propulsion seat 35 is provided with an inclined track 36. The first drive shaft 33 is slidably mounted in the inclined track 36.

[0059] Under the action of the positioning post 32, the correction seat 3 can only slide in a direction perpendicular to the support plate 1. During the sliding process, the propulsion seat 35 can control the sliding of the correction seat 3 through the cooperation of the inclined track 36 and the first drive shaft 33, so that it extends outside the support plate and abuts the patient's back, thereby applying thrust to the patient's spine and stretching the spine. This ensures that the back spine and muscles are in a normal structural position and stretch them during shoulder exercises to correct the shoulders and back. In addition, an elastic member 37 is provided between the propulsion seats 35 in the two sets of exercise units to apply resistance to the patient's shoulder movement, thereby improving the exercise effect.

[0060] like Figures 4 to 7As shown, in this embodiment, a plurality of through holes 31 are provided on the correction seat 3, and a correction column 41 extending outward is passed through the through hole 31. A driving mechanism connected to the correction column 41 is provided on the connecting arm 22, and the driving mechanism converts the swing of the connecting arm 22 into driving the plurality of correction columns 41 to move in a circumferential direction along the edge of the through hole 31. The driving mechanism includes a lifting seat 46 that is slidably arranged on one side of the support plate 1, and a control component connected to the lifting seat 46 is provided on the mounting cylinder 2. When the mounting cylinder 2 is rotated to any position, the swing of the connecting arm 22 on the mounting cylinder 2 is converted into driving the lifting seat 46 to rise and fall through the control component. The control component includes a mounting ring 25 that is slidably sleeved on the mounting cylinder 2 along the axis of the mounting cylinder 2, and a sliding frame 27 is provided on the mounting ring 25. A second driving shaft 24 is provided at one end of the connecting arm 22, and the second driving shaft 24 is slidably clamped on the sliding frame 27. A groove for the sliding frame 27 to move is provided at the hinge between the mounting cylinder 2 and the connecting arm 22. An arc frame 26 is provided on the mounting ring 25, and the arc frame 26 is slidably clamped on the lifting seat 46.

[0061] During the longitudinal swing arm movement, the connecting arm 22 can be driven to rotate along the hinge point between the connecting arm 22 and the mounting cylinder 2, thereby driving the second drive shaft 24 to move, and the cooperation between the second drive shaft 24 and the slide frame 27 can drive the mounting ring 25 to rise and fall, and the mounting cylinder 2 drives the mounting ring 25 and the arc frame 26 to follow the movement during the rotation process. No matter which position the mounting cylinder 2 rotates to, the connecting arm 22 can drive the lifting seat 46 to rise and fall through the arc frame 26 during the movement.

[0062] like Figure 6 、 7 As shown, in this embodiment, the drive mechanism also includes a connecting plate 4 disposed within the correction seat 3, multiple groups of correction posts 41 fixedly disposed on the connecting plate 4, and a linkage assembly connected to the connecting plate 4 disposed on the lifting seat 46. The linkage assembly converts the lifting and lowering of the lifting seat 46 into circumferential motion of the connecting plate 4 when the correction seat 3 slides to any position. The linkage assembly includes two groups of second gears 42 rotatably disposed on the correction seat 3, a drive post 43 eccentrically disposed on the second gear 42, and the drive post 43 is rotatably connected to the connecting plate 4. A third gear 44 is rotatably disposed along its axis on the correction seat 3, meshing with the two groups of second gears 42, and the third gear 44 has a larger diameter than the second gear 42. A connecting shaft 45 is eccentrically disposed on the third gear 44. A connecting rod 47 is hingedly connected to the lifting seat 46, and the other end of the connecting rod 47 is slidably sleeved on the connecting shaft 45 along the axis of the connecting shaft 45.

[0063] During the lifting process, the lifting seat 46 can drive the third gear 44 to rotate a certain angle through the connecting rod 47, thereby controlling the two sets of second gears 42 to rotate in the same direction at the same time. In addition, during the rotation of the second gear 42, the connecting plate 4 can be controlled to make circumferential translation through two sets of eccentrically arranged drive columns 43, thereby driving multiple sets of correction columns 41 to move circumferentially along the edge of the through hole 31 at the same time. This can not only massage the back muscles, but also apply a force toward the middle of the spine, thereby correcting the back posture. The resistance encountered by the correction column 41 during movement can also be used to apply resistance to the movement of the arm, thereby improving the exercise effect. In addition, it is understandable that in some embodiments, if the resistance encountered by the correction column 41 during movement is small, a torsion spring can be added at the hinge between the connecting arm 22 and the mounting cylinder 2 to further improve the exercise effect.

[0064] Specific usage and beneficial effects of the present invention:

[0065] When in use, the device can be placed on a seat, and the patient can lean on the support plate 1 and bind their arms with the straps 23 before exercising. The patient can perform transverse chest expansion exercises or longitudinal arm swinging exercises to perform multi-dimensional functional exercises on the shoulder muscles and joints, or combine transverse chest expansion exercises and longitudinal arm swinging exercises to simulate swimming swinging, so as to facilitate diversified shoulder exercises. During the exercise, the arm can drive the mounting tube 2 to rotate on the support plate 1, and at the same time drive the connecting arm 22 to swing on the mounting tube 2. During the rotation, the mounting tube 2 can drive the correction seat 3 to slide out of the support plate 1 through a propulsion mechanism to apply thrust to the back, thereby stretching the back spine. At the same time, during the swinging process, the connecting arm 22 can drive multiple groups of correction columns 41 along the edge of the through hole 31 through a driving mechanism to move in a circular direction, so as to massage and relax the muscles on both sides of the spine, and at the same time correct the spine, effectively preventing the back spine deformation of hemiplegic patients after long-term incorrect posture exercise, achieving posture correction and preventing abnormal upper limb patterns, reducing the risk of shoulder pain, and improving the rehabilitation efficiency of hemiplegic patients.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above.
