Description

Technical Field

[0001] This utility model relates to the field of hand exercise, specifically a hand exercise device for elderly care. Background Technology

[0002] With the accelerating aging of the global population and the continuous expansion of the elderly population, the health care needs of the elderly are becoming increasingly prominent. As an important functional organ for daily activities, the dexterity and strength of the hands directly affect the quality of life of the elderly. However, due to factors such as declining physiological function, chronic diseases (e.g., arthritis, post-stroke sequelae, Parkinson's disease), or prolonged bed rest, the elderly commonly experience problems such as muscle atrophy, joint stiffness, decreased grip strength, and reduced coordination in their hands, leading to limitations in their ability to perform daily activities independently, such as difficulty in grasping utensils, writing, and dressing.

[0003] The maintenance and recovery of hand function depends on continuous and targeted exercise. In existing technologies, some small hand exercise devices provide basic resistance training through mechanical structures, such as using springs, gears, or friction plates to adjust grip strength. For example, Chinese patent CN 220736100 U (Hand Exercise Device) includes a wrist sleeve and a trainer attached to the wrist sleeve. The trainer includes a buckle and finger sleeves worn on the fingers. The wrist sleeve has a perforation on its side wall, and the buckle is snapped into the perforation. A stretchable elastic bandage is provided between the buckle and the finger sleeve. It also includes a limiting part, which includes a sliding plate and a sliding bar for sliding the plate. In this hand exercise device, five finger sleeves are connected to the wrist sleeve via elastic bandages, allowing for precise training of each finger and enabling holistic training. The limiting part at the end of the pin allows for folding and extension, enabling quick fixation and disassembly of the elastic bandage and wrist sleeve, making it very convenient and easy to use.

[0004] While the aforementioned existing technology can perform individual finger exercises, the elastic bandage always adheres to the back of the finger. When an elderly person exerts force, the elastic bandage stretches and adheres even more closely to the back of the finger, increasing the force exerted by the elastic bandage on the back of the finger and increasing the tension of the elastic bandage. Since the skin of the elderly is more fragile, it is easily damaged under pressure and tension. Utility Model Content

[0005] The purpose of this invention is to provide a hand exercise device for elderly care, in order to solve the problem mentioned in the background art that the elastic bandage always fits the back of the finger, and when the elastic bandage is stretched, the force of the elastic bandage on the back of the finger increases, the tension of the elastic bandage increases, and the skin of the elderly is easily damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hand exercise device for elderly care, comprising a front fixing strip, the interior of which is configured as an inner hollow cavity, and finger exercise components and thumb exercise components connected to the front fixing strip. The finger exercise components and thumb exercise components have the same structure. Two thumb exercise components are disposed on both sides of the front fixing strip, and four finger exercise components are equidistantly disposed on the upper end of the front fixing strip. Each finger exercise component and thumb exercise component includes a hollow column, which passes through the upper end face or side face of the front fixing strip. A sliding groove is centrally formed on the outer end face of the hollow column. A limiting plate is slidably connected inside the hollow column. A connecting column is centrally fixed at the outer end of the limiting plate. The outer end of the connecting column passes through the sliding groove and is fixed with an outer pressure plate. The outer end face of the outer pressure plate has a pressing groove. A pressure spring is fixedly installed inside the hollow column along the inner end of the limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, finger exercise components and thumb exercise components are connected to the front fixing strip, with two thumb exercise components located on both sides of the front fixing strip and four finger exercise components equidistantly located at the upper end of the front fixing strip. The fingers are placed on the upper end of the outer pressure plate of the finger exercise component, and the thumb is placed on one side of the outer pressure plate of the thumb exercise component. The thumb and the other four fingers press the outer pressure plate in sequence or according to other rules. When pressing, the outer pressure plate drives the limiting plate to move in the hollow column through the connecting column. The pressure spring contracts under the pressing action and generates a certain resistance on the fingertips. Through the resistance provided by the pressure spring, the muscle strength and flexibility of the fingers can be effectively exercised, greatly improving the coordination and reaction ability of the fingers, significantly enhancing finger function, and effectively delaying the decline of finger function. This exercise method only provides resistance through the pressure spring, and does not exert pressure on the hands of the elderly. The absence of an elastic band means that there is no tension of an elastic band acting on the hands of the elderly, avoiding damage to the hands of the elderly.

[0015] (2) The utility model is provided with a rotating shaft, a rotating plate, a torsion spring, a middle column and other structures, which can adjust the position of the exercise device according to the exercise needs; bending the corresponding position downwards causes the angle of the front fixing bar and the middle column of the device to change, and the torsion spring will be driven to rotate. The resistance generated by the torsion spring plays a role in exercising the gripping function and wrist function.

[0016] (3) In this utility model, the fixing straps on the first fixing component and the second fixing component are hooked together using the hook and loop parts of Velcro to achieve a stable fixation of the device on the hand. The operation is simple, and the elderly can easily complete the fixing and disassembly operations. Moreover, the Velcro design allows the tightness of the fixing straps to be flexibly adjusted according to the individual's hand condition or the different fixing positions, ensuring that the device will not loosen or fall off during exercise, while also ensuring blood circulation in the hand and preventing discomfort caused by excessive fixation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-5 One embodiment provided by this utility model:

[0025] (1) Anterior fixation bar 1 and related structures for finger exercise

[0026] This device has a front fixing bar 1, the interior of which is configured as an inner hollow cavity 2. Finger exercise components 3 and thumb exercise components 4 are connected to the front fixing bar 1, and the finger exercise components 3 and thumb exercise components 4 have identical structures. Two thumb exercise components 4 are located on both sides of the front fixing bar 1, and four finger exercise components 3 are equidistantly located at the upper end of the front fixing bar 1. Both finger exercise components 3 and thumb exercise components 4 include a hollow column 5, which passes through the upper or side surface of the front fixing bar 1. A sliding groove 6 is centrally located on the outer end surface of the hollow column 5. A limiting plate 7 is slidably connected inside the hollow column 5. A connecting column 8 is centrally fixed at the outer end of the limiting plate 7. The outer end of the connecting column 8 passes through the sliding groove 6 and is fixed to an outer pressure plate 9. The outer end surface of the outer pressure plate 9 has a pressing groove. A pressure spring 10 is fixedly installed inside the hollow column 5 along the inner end of the limiting plate 7.

[0027] The fingers are placed on the upper end of the outer pressure plate 9 of the finger exercise component 3, and the thumb is placed on one side of the outer pressure plate 9 of the thumb exercise component 4. The thumb and the other four fingers press the outer pressure plate 9 in sequence or according to other patterns. When pressing, the outer pressure plate 9 drives the limiting plate 7 to move within the hollow column 5 through the connecting column 8. The pressure spring 10 contracts under the pressure and generates a certain resistance to the fingertips. The elderly can flexibly adjust the pressing method and frequency according to their own situation. Through the resistance provided by the pressure spring 10, the muscle strength and flexibility of the fingers can be effectively exercised, greatly improving the coordination and reaction ability of the fingers, enhancing finger function, and effectively delaying the decline of finger function.

[0028] (2) Exercise the rotational structures related to grasping and wrist function.

[0029] First rotating shafts 11 are provided on both sides of the front fixing bar 1 along the lower end of the thumb exercise piece 4. The outside of the first rotating shaft 11 is connected to one end of the first rotating plate 12. The other end of the first rotating plate 12 is rotatably connected to the second rotating plate 13 via a shaft. A second rotating shaft 14 is provided on the inner side of the other end of the second rotating plate 13. A fixing block 16 is provided on the inner side of the second rotating shaft 14. Torsion springs 15 are installed between the front fixing bar 1 and the first rotating plate 12 along the outside of the first rotating shaft 11, and between the fixing block 16 and the second rotating plate 13 along the outside of the second rotating shaft 14. A middle post 17 is fixed between the two fixing blocks 16. An outer buffer sleeve 18 is provided between the two fixing blocks 16 along the outside of the middle post 17. The outer buffer sleeve 18 is glued and fixed to the middle post 17. The outer buffer sleeve 18 can play a buffering role during exercise, reduce pressure, and improve the comfort of use.

[0030] When exercising the gripping function, the front fixing strip 1 is positioned at the upper end of the palm side of the fingers, and the position of the front fixing strip 1 is fixed by the first fixing unit 19. At this time, the middle post 17 is located at the lower end of the palm. When the fingers are bent downwards, the torsion spring 15 rotates, and the torsion spring 15 generates a certain resistance to the fingers and the palm.

[0031] When exercising wrist function, the front fixing strip 1 is placed at the upper end of the palm and fixed in position by the first fixing unit 19. At this time, the middle post 17 is located at the wrist position and is fixed in position by the second fixing unit 20. When the entire palm is bent downward, the torsion spring 15 rotates, generating a certain resistance on the arm and palm.

[0032] This rotating structure, combined with the design of the torsion spring 15, can simulate real hand gripping and wrist movement scenarios, providing scientific and reasonable resistance training for the hand and wrist, effectively exercising gripping ability and wrist strength, enhancing the endurance and explosive power of hand and wrist muscles, and greatly improving the overall function of the elderly's hands.

[0033] (3) Fixed unit related structure

[0034] A first fixing unit 19 is provided at the rear end of the front fixing strip 1, and a second fixing unit 20 is provided at the rear end of the fixing block 16 and the intermediate post 17. The second fixing unit 20 and the first fixing unit 19 are vertically aligned and structurally identical. Both the first fixing unit 19 and the second fixing unit 20 include a first fixing component 21 and a second fixing component 22, which are structurally symmetrical. Both the first fixing component 21 and the second fixing component 22 include a fixing plate 23 and a fixing strap 24. The fixing plate 23 on the first fixing unit 19 is fixed to the front fixing strip 1, and the fixing plate 23 on the second fixing unit 20 is fixed to the fixing block 16. One end of the fixing strap 24 is fixed to the fixing plate 23. The inner end face of the fixing strap 24 on the first fixing component 21 is a hook and loop fastener, and the outer end face of the fixing strap 24 on the second fixing component 22 is a hook and loop fastener. The fixing straps 24 on the first fixing component 21 and the fixing straps 24 on the second fixing component 22 are fixed by the hook and loop fastener fasteners.

[0035] When using the device, the first fixing unit 19 and the second fixing unit 20 are fixed in their respective positions. The device is securely fixed to the hand by hooking the fixing strap 24 on the first fixing component 21 and the fixing strap 24 on the second fixing component 22 using Velcro hooks and loops. This fixing unit design is easy to operate, allowing the elderly to easily fix and remove the device.

[0036] Finger exercise: The front fixing strip 1 is placed at the upper end of the palm, and the position of the front fixing strip 1 is fixed by the first fixing component 21 and the second fixing component 22 on the first fixing unit 19.

[0037] The fingers are placed on the upper end of the outer pressure plate 9 of the finger exercise component 3, and the thumb is placed on one side of the outer pressure plate 9 of the thumb exercise component 4 (the presence of two thumb exercise components 4 allows for exercise of both hands). The thumb and the other four fingers press the outer pressure plate 9 in turn or according to other rules, so that the limiting plate 7 moves in the hollow column 5. The pressure spring 10 contracts under the action of pressing and has a certain resistance force on the fingertips. Through repeated pressing, the muscle strength and flexibility of the fingers can be effectively exercised, greatly improving the coordination and reaction ability of the fingers, and has a significant effect on delaying the decline of finger function.

[0038] Exercise gripping function: The front fixing strip 1 is placed at the upper end of the palm side of the fingers and the position of the front fixing strip 1 is fixed by the first fixing unit 19; at this time, the middle post 17 is located at the lower end of the palm and the position of the middle post 17 is fixed by the first fixing component 21 and the second fixing component 22 on the second fixing unit 20.

[0039] When the fingers are bent downwards, the angle between the fingers and the palm changes, causing the front fixing bar 1 to rotate accordingly. The angle between the first rotating plate 12 and the second rotating plate 13 changes, causing the first rotating plate 12 to rotate relative to the front fixing bar 1 and the second rotating plate 13 to rotate relative to the fixing block 16. The torsion spring 15 is driven to rotate, and the torsion spring 15 provides some resistance to the fingers and palm, which helps to train gripping ability. This resistance training can simulate real gripping scenarios, effectively enhancing gripping ability and hand muscle endurance, making it easier and more powerful for the elderly to grasp objects in daily life.

[0040] Exercise wrist function: The front fixing strip 1 is placed at the upper end of the palm and the position of the front fixing strip 1 is fixed by the first fixing unit 19; at this time, the middle column 17 is located at the wrist position and the position of the middle column 17 is fixed by the second fixing unit 20.

[0041] Bending the entire palm downwards changes the angle between the palm and the arm, causing the first rotating plate 12 and the second rotating plate 13 to change the angle. The torsion spring 15 is then rotated. The torsion spring 15 provides some resistance to the arm and palm, thus exercising the wrist. This exercise method can significantly enhance wrist strength.

[0042] For some elderly people with less functional decline, when exercising grasping function, insert your fingers between the finger exercise pieces 3 to perform grasping training; when exercising wrist function, grasp the front fixing strip 1 to perform wrist training.

[0043] Under normal circumstances, the fixation strap 24 only serves a stabilizing function and will not easily move during movement, thus causing minimal skin damage. However, to further reduce the pressure injury of the fixation strap 24 on the elderly person's hand, a cotton loop can be attached to the outside of the fixation strap 24 on the second fixation component 22. This involves forming a loop structure with the side stitches of the cotton strip, which can move freely outside the fixation strap 24 and can be compressed. During fixation, the cotton loop is compressed to its minimum width along one side of the fixation strap 24, and the two fixation straps 24 are secured with Velcro. Then, the cotton loop is unfolded so that it is located outside the fixation strap 24, reducing pressure injury.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
