Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a height-adjustable vertical limb and hand function training device based on chess games. Background Technology

[0002] The recovery of limb and hand function has always been one of the most challenging issues in the rehabilitation of stroke and cervical spinal cord injury. Currently available hand function training tools are mostly placed directly on a tabletop, such as wooden pegboards, wooden pegboards, or ordinary chess / Go sets. These hand function training tools have fixed heights and do not require patients to raise their arms to manipulate objects; for example, a sleeve only trains finger columnar grasping and its height is not adjustable. Common tools that train patients to raise their arms to manipulate objects in mid-air only offer lifting capabilities, have limited functionality, and are almost irrelevant to patients' daily lives. For example, shoulder lift trainers involve bilateral movements and place less emphasis on the affected hand.

[0003] However, most of an individual's daily actions require raising their arms to manipulate objects, such as reaching for a water glass on a table, taking down a hanging towel or a toothbrush placed high up, using chopsticks to pick up food, and waving goodbye. These everyday actions require individuals to coordinate the movement of multiple joints, such as the shoulder, elbow, wrist, and fingers, in multiple directions while the arm is suspended in the air. Training devices placed on a table with fixed height cannot achieve this training purpose.

[0004] Chinese chess and Go are two-player games where players move pieces on a board according to certain rules. They are cognitive and recreational activities, typically played on a table without electronic devices. These games are not only competitive, but also require the use of motor skills (arms and hands) and cognitive skills such as concentration, memory, verbal fluency, planning, and calculation. Studies have found that board games, as a form of cognitive stimulation, can effectively improve cognitive function and interpersonal interaction in the elderly and patients with brain injuries. Furthermore, board games help train hand-grasping function; however, existing board games are all flat on the table, making it impossible to adjust the height to train the lifting function of patients' arms.

[0005] The above problems could be solved if a device could be developed that trains hand gripping function through board games and trains arm lifting ability by raising and lowering the height of the board. Utility Model Content

[0006] The purpose of this invention is to provide a height-adjustable vertical limb and hand function training device based on chess games. This height-adjustable vertical limb and hand function training device based on chess games can solve the problems that most existing hand function training tools are placed directly on the table and cannot be adjusted in height to train the lifting ability of the limbs and arms. Moreover, existing common tools for training patients to raise limbs and arms in the air can only be raised, have limited functions, and are not related to daily life.

[0007] To achieve the above objectives, this utility model provides a height-adjustable vertical limb and hand function training device based on chess games, the specific implementation of which is as follows:

[0033] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0034] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0035] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0036] Please see Figures 1 to 8This invention relates to a height-adjustable vertical limb and hand function training device based on chess games, comprising a chessboard mechanism 10 and a lifting mechanism 20. The chessboard mechanism 10 includes a Chinese chess board 11, a Go board 13 opposite to the Chinese chess board 11, Go pieces 14 matching the Go board 13, and Chinese chess pieces (12a, 12b) matching the Chinese chess board 11. The chessboard faces of the Chinese chess board 11 and the Go board 13 are arranged facing away from each other. To facilitate the patient's movement of Go pieces 14 on the Go board 13 and Chinese chess pieces (12a, 12b) on the Chinese chess board 11, the chessboard 11 and the Go board 13 are positioned with their sides facing each other. The chessboard 13 is tilted downwards towards the direction away from each other; the chess pieces (12a, 12b) are cylindrical; to prevent the Go pieces 14 and the chess pieces (12a, 12b) from falling, the Go pieces 14 and the chess pieces (12a, 12b) are magnetically fixed to the Go board 13 and the chessboard 11 respectively, that is, the Go piece 14 is magnetically fixed to the Go board 13, and the chess pieces (12a, 12b) are magnetically fixed to the chessboard 11; the lifting mechanism 20 is connected to the chessboard mechanism 10 and is used to adjust the height of the chessboard mechanism 10 according to the rehabilitation needs of the patient's limbs and hands.

[0037] This invention, by setting a lifting mechanism 20 for the chessboard mechanism 10, allows the height of the Go board 13 and the Chinese chess board 11 of the chessboard mechanism 10 to be adjusted. This is suitable for patients with varying shoulder elevation abilities. The height of the Go board 13 and the Chinese chess board 11 can be gradually increased as shoulder flexion and abduction muscle strength improves, providing the optimal training height for the patient. The invention includes a Chinese chess board 11, matching Chinese chess pieces (12a, 12b), a Go board 13, and matching Go pieces 14. The Chinese chess pieces (12a, 12b) are cylindrical. The chessboard 11 and the Chinese chess pieces (12a, 12b) together form a chessboard... The chess games, including the chessboard 13 and Go pieces 14, are grasping and intellectual games in daily life. For patients with no grasping function in their fingers, they can move the chess pieces (12a, 12b) by shaking their hands (Bobath). For patients with group grasping function in their fingers, they can play chess by holding the chess pieces (12a, 12b) in their hands. For those with better hand function, they can play chess by pinching or holding the Go pieces 14 between their thumb and index finger (or middle finger). Therefore, chess pieces (12a, 12b) can be used to exercise the hand's ability to grasp relatively large objects, while Go pieces 14 can be used to exercise the fingers' ability to pinch and hold delicate objects. In summary, this invention achieves multifunctionality by combining lifting function with the function of chess games in daily life. It can not only train hand grasping function, but also train the lifting and suspension ability of limbs and arms. This invention can be applied to limb and hand dysfunction caused by various diseases, such as stroke, traumatic brain injury, cervical spinal cord injury, and frozen shoulder.

[0038] In one embodiment, such as Figures 1 to 3 As shown, the lifting mechanism 20 includes a base 21, a vertical rod 22, a sleeve rod 23, a top plate 24, a first mounting plate 25, and a second mounting plate 26. The base 21 is placed on the ground and serves to bear weight. The vertical rod 22 is fixed to the top of the base 21. One end of the sleeve rod 23 can be slidably sleeved around the outside of the vertical rod 22 and is fixed to the vertical rod 22 by a fastening element (not shown in the figure) when it is moved to the desired height position. The other end of the sleeve rod 23 is connected to the bottom of the top plate 24. The first mounting plate 25 and the second mounting plate 26 are respectively fixed to the two ends of the top plate 24 and are respectively connected to the chessboard 11 and the Go board 13.

[0039] In use, the sleeve 23 is moved relative to the upright 22 so that the sleeve 23 can push the chessboard 11 and the Go board 13 to rise and fall, thereby adjusting the height of the chessboard 11 and the Go board 13. After adjustment, the sleeve 23 is fixed to the upright 22 by fastening elements.

[0040] In this embodiment, the fastening element is a bolt. Correspondingly, the upright 22 is provided with a plurality of first adjustment holes 221 spaced apart along the length direction of the upright 22, and the sleeve 23 is provided with a plurality of second adjustment holes 231 spaced apart along the length direction of the sleeve 23. At least one first adjustment hole 221 and one second adjustment hole 231 coincide. The bolt passes through the coincident first adjustment hole 221 and second adjustment hole 231 and is threadedly engaged with the first adjustment hole 221 and / or the second adjustment hole 231, so that when the bolt can fix the sleeve 23 to the upright 22, it will not fall off the sleeve 23. In other embodiments, the fastening element can also be a "T"-shaped smooth rod. The smooth rod passes through the coincident first adjustment hole 221 and second adjustment hole 231 and is locked with the first adjustment hole 221 and / or the second adjustment hole 231 to fix the sleeve 23 to the upright 22.

[0041] In other embodiments, the number of second adjustment holes 231 can be set to one instead of several. The second adjustment hole 231 is located at the end of the sleeve rod 23 away from the top plate 24. When adjusting the height of the chessboard mechanism 10, the sleeve rod 23 is moved until the chessboard mechanism 10 reaches the required height, and the second adjustment hole 231 is made to coincide with one of the first adjustment holes 221 on the upright rod 22, so that the fastening element can pass through the overlapping first adjustment hole 221 and second adjustment hole 231, thereby fixing the sleeve rod 23 in the correct position to the upright rod 22.

[0042] In one embodiment, such as Figure 6 and Figure 8 As shown, the first mounting plate 25 is detachably connected to the chessboard 11. A chessboard fixing rod 114 is provided on the back of the chessboard 11. A first through hole 251 is provided on the first mounting plate 25 corresponding to the chessboard fixing rod 114. The chessboard fixing rod 114 passes through the first through hole 251 and is secured to it, thus fixing the chessboard 11 to the first mounting plate 25. When the chessboard 11 needs to be removed from the first mounting plate 25, the chessboard 11 is pulled outwards forcefully, pulling the chessboard fixing rod 114 out of the first through hole 251, thereby separating the chessboard 11 from the first mounting plate 25.

[0043] Optionally, the number of chessboard fixing rods 114 is four, arranged in two rows and two columns, and correspondingly, the number of first perforations 251 is also four, also arranged in two rows and two columns.

[0044] In one embodiment, such as Figure 2 As shown, the chessboard 11 has recessed circular holes 113 corresponding to the chess pieces (12a, 12b) on its surface. One end of each chess piece (12a, 12b) is inserted into the recessed circular hole 113 and magnetically attracted to the chessboard 11, while the other end of the chess piece (12a, 12b) extends out of the recessed circular hole 113. Further, as... Figure 4 and Figure 5 As shown, the chess pieces (12a, 12b) include a magnetic insertion section 122 and an extension section 121 connected to each other. The magnetic insertion section 122 is used to insert into the recessed circular hole 113 and magnetically attract the chessboard 11. The extension section 121 is located outside the recessed circular hole 113 and is used by the patient to hold it. Chess characters are set on the top surface of the extension section 121 so that the user can accurately identify each chess piece (12a, 12b). In this embodiment, the chess pieces (12a, 12b) are divided into two types, namely as follows: Figure 4 The first type of chess piece 12a shown and as follows Figure 5 As shown in the second type of chess piece 12b, Figure 4 As shown, the outer diameters of the magnetic insertion section 122 and the extension section 121 of the first type of chess piece 12a are the same, as... Figure 5 As shown, the outer diameter of the magnetic insertion section 122 of the second type chess piece 12b is smaller than the outer diameter of the protrusion section 121, and the size of the magnetic insertion section 122 of the second type chess piece 12b is equal to the size of the magnetic insertion section 122 of the first type chess piece 12a. It can be seen that the outer diameter of the protrusion section 121 of the second type chess piece 12b is larger than that of the protrusion section 121 of the first type chess piece 12a. This arrangement allows the protrusion sections 121 of the chess pieces (12a, 12b) to be of two thicknesses. If the patient's grip strength is weak, they can choose the second type chess piece 12b with the thicker protrusion section 121, which is easier to grasp; if the patient's grip strength is strong, they can choose the first type chess piece 12a with the thinner protrusion section 121 to further improve their grip strength. Furthermore, it is possible to configure the first type of chess piece 12a and the second type of chess piece 12b to be entirely made of magnetic material, so as to achieve the purpose of magnetic attraction between the chess pieces (12a, 12b) and the chessboard 11. Alternatively, only the magnetic insertion section 122 of the first type of chess piece 12a and the magnetic insertion section 122 of the second type of chess piece 12b can be made of magnetic material. Alternatively, only the end of the magnetic insertion section 122 of the first type of chess piece 12a away from the protrusion section 121 can be made of magnetic material, and the end of the magnetic insertion section 122 of the second type of chess piece 12b away from the protrusion section 121 can also be made of magnetic material.

[0045] Optional, such as Figure 6 and Figure 8As shown, the chessboard 11 includes a magnetic layer 111 and a non-magnetic layer 112 connected together. The magnetic layer 111 is attached to the first mounting plate 25, and the non-magnetic layer 112 is located on the side of the magnetic layer 111 away from the first mounting plate 25. The chessboard fixing rod 114 is provided on the side of the non-magnetic layer 112 close to the first mounting plate 25. A recessed circular hole 113 is provided on the non-magnetic layer 112. One end of the recessed circular hole 113 near the magnetic layer 111 extends to the magnetic layer 111, so that the magnetic layer 111 is exposed inside the recessed circular hole 113. Therefore, after the magnetic insertion section 122 of the chess pieces (12a, 12b) is inserted into the recessed circular hole 113, it can adhere to the magnetic layer 111 of the chessboard 11, achieving the beneficial effect of fastening the magnetic attraction.

[0046] Preferably, the non-magnetic layer 112 of the chessboard 11 is made of PP material.

[0047] In other feasible embodiments, the end of the recessed circular hole 113 away from the first mounting plate 25 is tapered, and this end of the recessed circular hole 113 gradually increases in size in the direction away from the first mounting plate 25. This arrangement allows the user to quickly and accurately insert cylindrical chess pieces (12a, 12b) into the recessed circular hole 113.

[0048] In one embodiment, the second mounting plate 26 is detachably connected to the Go board 13, such as... Figure 7 and Figure 8 As shown, the back of the Go board 13 is provided with a Go board fixing rod 131. The second mounting plate 26 has a second through hole 261 corresponding to the Go board fixing rod 131. The Go board fixing rod 131 passes through the second through hole 261 and is secured therein, thus fixing the Go board 13 to the second mounting plate 26. When the Go board 13 needs to be removed from the second mounting plate 26, pull the Go board 13 outwards to pull the Go board fixing rod 131 out of the second through hole 261, thereby separating the Go board 13 from the second mounting plate 26.

[0049] Optionally, the entire Go board 13 is a disk structure made of magnetic material.

[0050] Optionally, the number of Go board fixing rods 131 is four, arranged in two rows and two columns. Correspondingly, the number of second perforations 261 is also four, also arranged in two rows and two columns.

[0051] In one embodiment, both the upright 22 and the sleeve 23 are square tubular structures. In other feasible embodiments, the upright 22 may also be circular, triangular, polygonal, or other structures.

[0052] In one embodiment, the base 21, the upright 22, the sleeve 23, the top plate 24, the first mounting plate 25, and the second mounting plate 26 are all made of steel.

[0053] To prevent the lifting mechanism 20 from rusting, the base 21, the upright 22, the top plate 24, the second mounting plate 26, and the outer surfaces of the second mounting plate 26 are all coated with an anti-corrosion layer.

[0054] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
