Description

Technical Field

[0001] This invention specifically relates to a hand exercise device for preventing Alzheimer's disease. Background Technology

[0002] Alzheimer's disease is a common neurodegenerative disease that causes a gradual loss of memory, thinking, and behavioral abilities. Currently, although many treatments and technologies exist for Alzheimer's, there is still no way to completely cure or prevent it. Prevention and mitigation can only be achieved through various daily exercises.

[0003] Currently, the most commonly used exercise method is finger exercise. Finger exercise can assess the dexterity of an elderly person's fingers and also check for any abnormalities in limb and nerve function. By performing finger exercises in their daily lives, the elderly can fully exercise the cerebral cortex and strengthen the function of local nerves, thereby preventing and alleviating Alzheimer's disease.

[0004] For example, Chinese invention patent application number 202110150577.0 provides a hand exercise device for preventing Alzheimer's disease in geriatrics. In use, the hand passes through the gap between the fixed plate and the main body, and the fingers press a first button and a second button. A spring applies resistance to the first and second buttons to exercise the fingers. However, most existing hand exercise devices for preventing Alzheimer's disease are single-function and cannot stimulate the nerves in the hands of the elderly during exercise, thus reducing their effectiveness in preventing Alzheimer's disease. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a hand exercise device for preventing Alzheimer's disease. This addresses the technical problem mentioned in the background section: most existing hand exercise devices for preventing Alzheimer's disease have limited functions and cannot stimulate the nerves in the hands of the elderly during exercise, thus reducing their effectiveness in preventing Alzheimer's disease.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hand exercise device for preventing Alzheimer's disease, comprising:

[0016] Preferably, the unidirectional drive mechanism includes:

[0017] The movable plate is slidably disposed inside the housing along the sliding direction of the first pressure block, and is located outside the horizontal plate, and abuts against the ends of the four sets of the first pressure blocks;

[0018] The return spring has two ends that abut against the movable plate and the L-shaped frame, respectively.

[0019] A mounting plate is disposed on the second pressure block; and

[0020] The drive assembly comprises two sets, which are respectively disposed on the movable plate and the mounting plate and connected to the drive shaft to drive the drive shaft to rotate during the sliding of the movable plate and the mounting plate.

[0021] Preferably, the driving component includes:

[0022] The mounting brackets are arranged in two sets at intervals, and the mounting brackets in the two sets of drive components are respectively fixedly connected to the movable plate and the mounting plate;

[0023] Two sets of ratchet racks are provided, and are respectively located on opposite sides of the two sets of mounting brackets, and the two sets of ratchet racks are arranged symmetrically along the axis of the drive shaft.

[0024] An elastic element is disposed between the ratchet rack and the mounting bracket; and

[0025] A ratchet is mounted on the drive shaft, and both sets of ratchet racks mesh with the ratchet.

[0026] Preferably, the housing is further provided with an adjustment unit connected to the drive shaft, and the adjustment unit is used to adjust the resistance encountered by the drive shaft during rotation.

[0027] Preferably, the adjustment unit includes:

[0028] The support frame is fixedly installed inside the housing;

[0029] A friction ring is mounted on the drive shaft and rotatably mounted on the support frame;

[0030] A knob, rotatably mounted on the housing; and

[0031] A friction mechanism is disposed inside the friction ring and connected to the knob. During the rotation of the knob, the friction force on the friction ring is adjusted by the friction mechanism.

[0032] Preferably, the friction mechanism includes:

[0033] A stop block is slidably mounted on the support frame;

[0034] The mounting rod is slidably inserted through the stop block. The end of the mounting rod is provided with an abutment block, and a friction pad is provided on the abutment block. The friction pad contacts the inner side of the friction ring.

[0035] A pressure spring is disposed on the stop block between it and the abutment block; and

[0036] A push component is disposed on the knob and connected to the stop block, and the stop block is driven to slide through the push component during the rotation of the knob.

[0037] Preferably, the pushing component includes a mounting plate, which is disposed on the knob, and multiple sets of push blocks are arranged circumferentially on the mounting plate, with the distance between the ends of the multiple sets of push blocks and the center of the mounting plate increasing sequentially.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. When using this device, the patient holds it with their thumb pressing on the second pressure block and the other four limbs pressing on the first pressure block. By pressing the first and second pressure blocks, the device slides along the housing. During this sliding process, the resistance generated by the first and second pressure blocks through the resistance mechanism trains the fingers. During training, the sliding motion of the first and second pressure blocks can be converted into a force controlling the rotation of the drive shaft via a unidirectional drive mechanism. The rotation of the drive shaft drives the mounting base to rotate, thereby massaging the patient's palm through multiple massage heads to stimulate the nerves in the hand and improve the effect of preventing Alzheimer's disease.

[0042] 2. In use, the device can also rotate the mounting plate by turning the knob. Push blocks of different heights on the mounting plate push the stop blocks to slide on the support frame. With the help of locking blocks and slots, the push blocks and stop blocks are fixed together. During the sliding process, the stop blocks apply different pressures to the pressure spring, thereby adjusting the friction force between the friction pad and the friction ring in multiple levels. This adjusts the resistance encountered by the drive shaft during rotation, thus adjusting the resistance encountered by the first and second pressure blocks during exercise. This allows for easy adjustment of training intensity according to different groups of people, increasing the applicability of the device. Attached Figure Description

[0057] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0058] Example:

[0059] like Figures 1 to 3 As shown, the present invention provides a hand exercise device for preventing Alzheimer's disease, including a housing 101. Four sets of slidably mounted first pressure blocks 102 and one set of second pressure blocks 105 are disposed on the housing 101. A resistance mechanism is disposed within the housing 101 to apply resistance to the sliding of the first pressure blocks 102 and second pressure blocks 105. The resistance mechanism includes a horizontal plate 103 and an L-shaped frame 107 fixedly disposed within the housing 101. The four sets of first pressure blocks 102 are slidably engaged on the horizontal plate 103, and the second pressure blocks 105 are slidably engaged on the L-shaped frame 107. A first exercise spring 104 is disposed between the horizontal plate 103 and the first pressure blocks 102, and a second exercise spring 108 is disposed between the L-shaped frame 107 and the second pressure blocks 105.

[0060] When using the device, the patient holds it in their hand, presses the second pressure block 105 with their thumb, and presses the four sets of first pressure blocks 102 with their other four fingers. During the pressing process, the first exercise spring 104 and the second exercise spring 108 deform, thereby applying resistance to the fingers to achieve the purpose of exercising the fingers. The first pressure block 102 and the second pressure block 105 can be controlled to return to their original position by the return ability of the first exercise spring 104 and the second exercise spring 108, so that the first pressure block 102 and the second pressure block 105 can slide back and forth.

[0061] like Figure 1 , 3 As shown in Figure 4, in this embodiment, a rotatable drive shaft 301 is provided inside the housing 101. A mounting base 303 is provided at one end of the drive shaft 301, and a massage head 304 is provided on the mounting base 303. A one-way drive mechanism is provided inside the housing 101, which is connected to four sets of first pressure blocks 102 and one set of second pressure blocks 105. The sliding of the first pressure blocks 102 and the second pressure blocks 105 is converted into controlling the rotation of the drive shaft 301 through the one-way drive mechanism.

[0062] The unidirectional drive mechanism includes a movable plate 201 slidably disposed within the housing 101 along the sliding direction of the first pressure block 102. The movable plate 201 is located outside the horizontal plate 103 and abuts against the ends of the four sets of first pressure blocks 102. A return spring 202 is disposed between the movable plate 201 and the L-shaped frame 107. A mounting plate 106 is disposed on the second pressure block 105. It also includes two sets of drive assemblies, which are respectively disposed on the movable plate 201 and the mounting plate 106 and connected to the drive shaft 301 to control the rotation of the drive shaft 301 during the sliding of the movable plate 201 and the mounting plate 106.

[0063] The drive assembly includes two sets of spaced mounting brackets 203, which are fixedly connected to the movable plate 201 and the mounting plate 106, respectively. It also includes two sets of ratchet racks 204, which are respectively arranged on opposite sides of the two sets of mounting brackets 203 and are symmetrically arranged along the axis of the drive shaft 301. An elastic element 205 is provided between the ratchet racks 204 and the mounting brackets 203. A ratchet wheel 302 is provided on the drive shaft 301, and both sets of ratchet racks 204 mesh with the ratchet wheel 302.

[0064] When the first pressure block 102 is pressed, the movable plate 201 slides within the housing 101, causing the two sets of mounting brackets 203 on the movable plate 201 to move accordingly. After the first pressure block 102 is released, the movable plate 201 is reset by the return spring 202, allowing the two sets of mounting brackets 203 to slide back and forth. Similarly, when the second pressure block 105 is pressed, the other two sets of mounting brackets 203 move accordingly. During the movement of the mounting brackets 203, the ratchet rack 204 moves, and under the action of the elastic element 205, one side of the ratchet rack 204 engages with the ratchet wheel 302, while the other side of the ratchet wheel 302 slides and compresses the elastic element 205, driving the ratchet wheel 302 to rotate unidirectionally. During the rotation of the ratchet wheel 302, the mounting base 303 rotates, allowing the massage head 304 to massage the patient's palm, stimulating the nerves in the palm and thus improving the effect of preventing Alzheimer's disease.

[0065] Furthermore, after pressing the first pressure block 102 or the second pressure block 105, during the reset process of the return spring 202 and the second exercise spring 108, the first pressure block 102 or the second pressure block 105 can always maintain the engagement of the ratchet rack 204 and the ratchet wheel 302, so that the massage head 304 can rotate continuously, thereby improving the stimulation effect. At the same time, each finger can be trained individually, further improving the exercise effect.

[0066] like Figure 1 , 2 As shown in Figure 5, in this embodiment, the housing 101 is also provided with an adjustment unit connected to the drive shaft 301, which adjusts the resistance encountered by the drive shaft 301 during rotation. The adjustment unit includes a support frame 401 fixedly installed inside the housing 101, and a friction ring 305 is provided on the drive shaft 301, which is rotatably mounted on the support frame 401.

[0067] When the first pressure block 102 or the second pressure block 105 is pressed, the drive shaft 301 is driven to rotate, thereby causing the friction ring 305 to rotate on the support frame 401. The resistance experienced by the first pressure block 102 or the second pressure block 105 when pressed can be adjusted by adjusting the friction force experienced by the friction ring 305, so as to adjust the exercise intensity according to different groups of people, thus improving the applicability of the device.

[0068] like Figures 5 to 7As shown, in this embodiment, the adjustment unit further includes a knob 501 rotatably mounted on the housing 101. A friction mechanism connected to the knob 501 is provided inside the friction ring 305. During the rotation of the knob 501, the friction force on the friction ring 305 is adjusted through the friction mechanism. The friction mechanism includes a stop block 402 slidably mounted on the support frame 401. A mounting rod 403 is slidably mounted on the stop block 402. An abutment block 404 is provided at the end of the mounting rod 403. A friction pad 405 is provided on the abutment block 404. The friction pad 405 contacts the inner side of the friction ring 305. A pressure spring 406 is provided between the stop block 402 and the abutment block 404. A pushing component connected to the stop block 402 is provided on the knob 501. During the rotation of the knob 501, the pushing component drives the stop block 402 to slide. The pushing component includes a mounting plate 502 disposed on the knob 501, and multiple sets of push blocks 503 are arranged circumferentially on the mounting plate 502, with the distance between the ends of the multiple sets of push blocks 503 and the center of the mounting plate 502 increasing sequentially.

[0069] During the process of rotating the drive shaft 301 by pressing the first pressure block 102 or the second pressure block 105, the friction ring 305 and the friction pad 405 move relative to each other. The friction pad 405 generates resistance on the friction ring 305, thereby increasing the resistance experienced when pressing the first pressure block 102 or the second pressure block 105. The mounting plate 502 can be rotated by rotating the knob 501. During the rotation of the mounting plate 502, one set of push blocks 503 abuts against the stop block 402. The stop block 402 can slide on the support frame 401 by using push blocks 503 at different heights. During the sliding process, the stop block 402 can compress the pressure spring 406, thereby increasing the resistance between the friction pad 405 and the friction ring 305, and thus increasing the resistance experienced when pressing the first pressure block 102 or the second pressure block 105. This allows for adjustment of the resistance experienced when pressing the first pressure block 102 and the second pressure block 105, so as to adjust the exercise intensity for different groups of people.

[0070] like Figure 2 , 6 As shown in Figure 7, in this embodiment, a slot is provided at the end of the push block 503, and a locking block is provided on the stop block 402. The locking block can be locked in the slot. The position of the push block 503 can be assisted and fixed by the cooperation of the slot and the locking block, so that the push block 503 is not easy to disengage from the stop block 402, thereby improving the stability of the internal structure of the device. An indicator scale 504 is arranged circumferentially on the outer surface of the knob 501 on the housing 101. The position of the knob 501 can be precisely adjusted by the indicator scale 504, so as to conveniently and intuitively know the current exercise level and realize multi-level adjustment of exercise intensity.

[0071] Specific usage and beneficial effects of the present invention:

[0072] When using the device, the patient can hold it with their thumb pressing on the second pressure block 105 and the other four limbs pressing on the first pressure block 102. By pressing the first and second pressure blocks 102 and 105, the device slides on the housing 101. During this sliding process, the resistance generated by the resistance mechanism on the first and second pressure blocks 102 and 105 trains the fingers. During the training process, the sliding of the first and second pressure blocks 102 and 105 can be converted into a force controlling the rotation of the drive shaft 301 through a one-way drive mechanism. As the drive shaft 301 rotates, it drives the mounting base 303 to rotate, thereby massaging the patient's palm through multiple sets of massage heads 304 to stimulate the nerves in the patient's hand and thus improve the effect of preventing Alzheimer's disease.

[0073] When in use, the device can also rotate the mounting plate 502 by turning the knob 501. The push blocks 503 at different heights on the mounting plate 502 push the stop block 402 to slide on the support frame 401. The push blocks 503 and the stop block 402 are then fixed together by the locking blocks and the locking slots. During the sliding process, the stop block 402 applies different pressures to the pressure spring 406, thereby adjusting the friction between the friction pad 405 and the friction ring 305 in multiple levels. This adjusts the resistance encountered by the drive shaft 301 during rotation, thereby adjusting the resistance encountered by the first pressure block 102 and the second pressure block 105 during exercise. This allows for easy adjustment of the training intensity according to different groups of people, increasing the applicability of the device.

[0074] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
