Description

TECHNICAL FIELD

[0001] The utility model relates to walking auxiliary appliance especially a walking auxiliary device for cerebral palsy children. BACKGROUND

[0002] Cerebral palsy (CP) is a group of non-progressive movement disorder syndromes caused by abnormal brain development or brain injury in early stage. This disease seriously affects the motor function development of children, and one of the most notable manifestations is the difficulty in standing and walking. For cerebral palsy children, independent walking is not only a basic life skill, but also a key to integrate into society and improve the quality of life. However, due to poor muscle control ability, lack of balance and insufficient coordination, many cerebral palsy children face great challenges when walking.

[0003] In order to help cerebral palsy children achieve the goal of independent walking, various auxiliary tools are usually used in the medical and rehabilitation field. Among them, the crutch type tool is one of the most common choices. This kind of tool includes but is not limited to standard crutch, multi-foot crutch, underarm crutch and forearm crutch, etc. The original intention of the design of these auxiliary tools is to provide additional support points for the user to increase the stability and balance when walking. For some patients with motor disorders, these tools can indeed play a good auxiliary effect. However, for cerebral palsy children, traditional crutch type auxiliary tools often fail to meet their special needs. This is mainly because the motor disorder of cerebral palsy children is not just a problem of insufficient strength, but a complex motor balance control disorder caused by damage to the nervous system. The balance dysfunction (lack of balance) caused by cerebral palsy makes it still difficult to keep the body stable when using crutches. SUMMARY

[0052] The cerebral palsy child walking auxiliary device is described in detail below with reference to the drawings.

[0053] Referring to Figs. 1 to 3 As shown in the drawings, the cerebral palsy child walking auxiliary device provided by the present utility model comprises a chassis 10, two handrails 20 and a supporting plate 30.

[0054] The chassis 10 has a standing space suitable for a user to stand, and the rear of the standing space is open to form an entrance and exit for the user. The chassis 10 can be made of stainless steel or other materials, for example, it can be composed of stainless steel pipes, which maintains a lightweight design and has the required strength. The chassis 10 can be moved on the ground and can keep the device stable on the ground. The standing space on the chassis 10 is used for cerebral palsy children to stand, and they can take steps forward in the space. The rear of the standing space is open, forming an entrance and exit for the user, which makes it easy for cerebral palsy children to enter or leave the auxiliary device with the help of others, increasing the convenience and safety of use.

[0055] The two handrails 20 are respectively arranged on the left and right sides of the chassis 10, and each handrail 20 extends in the upward and downward direction. When in use, by holding the two handrails 20, cerebral palsy children can obtain support, which helps to maintain body balance and improve stability when walking.

[0056] The supporting plate 30 is horizontally arranged between the two handrails 20, and one end of the supporting plate 30 is connected to one of the two handrails 20, and the other end of the supporting plate 30 is connected to the other of the two handrails 20, and the supporting plate 30 is configured to be slidable in the upward and downward direction and can be selectively locked and fixed at different height positions.

[0057] The supporting plate 30 can be made of metal, wood or other materials, which is in a strip structure extending in the left-right direction. In order to improve the comfort of the user, a soft pad can be arranged on the surface of the supporting plate 30. The supporting plate 30 is connected between the two handrails 20, ensuring the stability and reliability of the supporting plate 30. In addition, the supporting plate 30 is designed to slide along the vertical direction and can be locked and fixed at different height positions. Such adjustability enables the auxiliary device to adapt to children with cerebral palsy of different heights and needs, greatly improving the universality and adaptability of the device, so that they can maintain the most comfortable and effective posture during use.

[0058] The main function of the supporting plate 30 is to provide a support platform and a temporary resting platform for the user. When the cerebral palsy child uses the auxiliary device to walk, after the auxiliary device moves forward, if the user has difficulty moving the body, the upper body can be placed on the supporting plate 30, and then the lower body is moved. In this way, the upper and lower bodies are alternately moved back and forth to achieve slow walking. In addition, after walking for a period of time, when they feel tired and need to rest, the upper body can be gently placed on the supporting plate 30 for a short rest. This design takes into account the possible lack of mobility and insufficient physical strength of children with cerebral palsy, allowing them to use the supporting plate 30 for assistance during walking or to take a short rest on the supporting plate 30. In this way, the comfort of use is improved, and the time that the cerebral palsy child can continuously use the auxiliary device is prolonged, which is beneficial for them to walk for a longer time.

[0059] According to the cerebral palsy child walking auxiliary device provided by the embodiment of the utility model, the whole forms a half-enclosed support design, has good stability and support, and can effectively assist cerebral palsy children to walk. The open design of the chassis 10 enables the user to conveniently enter and exit the device, reducing the use obstacle. The handrails 20 on both sides provide stable support points for the user, which helps to maintain balance and posture control. The supporting plate 30 is designed not only to provide additional support for the user during walking, but also to serve as a platform for short rest. When the cerebral palsy child feels tired, the upper body can be placed on the supporting plate 30 for rest. This design takes into account the characteristics of insufficient physical strength of children with cerebral palsy, effectively prolonging their activity time. The height adjustability of the supporting plate 30 further enhances the adaptability of the device, which can meet the needs of users of different heights and needs.

[0060] In some embodiments of the utility model, the front end of the chassis 10 is provided with two fixed legs 103, and the two fixed legs 103 are respectively located on the left and right sides of the chassis 10. The rear end of the chassis 10 is provided with two universal casters 104, and the two universal casters 104 are respectively located on the left and right sides of the chassis 10.

[0061] Two fixed feet 103 form a stable front support point. After the walking aid is moved forward by one position, the two fixed feet 103 are supported on the ground to keep the device stable. The fixed feet 103 are usually made of non-slip material, which can effectively prevent the device from sliding accidentally during use, thereby enhancing the user's sense of security and confidence.

[0062] In contrast, the rear end of the chassis 10 is equipped with two universal casters 104. The two universal casters 104 constitute the rear support point of the device. The use of universal casters 104 greatly improves the flexibility and maneuverability of the entire auxiliary device. The universal casters 104 can rotate 360 degrees, improving the flexibility of the user when walking, and even turning in a narrow space. In addition, when moving the walking aid forward, the two fixed feet 103 move away from the back, and the walking aid can be moved forward, with the universal casters 104 rolling on the ground, making it easier and more labor-saving to move.

[0063] In this embodiment, the combination of fixed feet 103 and universal casters 104 ensures the stability of the device in the forward direction while making the device more flexible or convenient, so that the entire auxiliary device can adapt to various complex use environments.

[0064] In some embodiments of the present application, the rear end of the chassis 10 is also provided with two adjustable feet 105, and the two adjustable feet 105 are respectively located on the left and right sides of the chassis 10. The height of each adjustable foot 105 in the vertical direction is adjustable, so that the lowest point of the adjustable foot 105 can be adjusted above or below the lowest point of the universal caster 104. According to the needs of the user, the rear end can be grounded using adjustable feet 105 or universal casters 104.

[0065] That is, each adjustable foot 105 is designed to be adjustable in height in the vertical direction. This adjustment capability allows the lowest point of the adjustable foot 105 to be flexibly adjusted above or below the lowest point of the universal caster 104. In this way, two different rear end support modes are provided for the user, which can be selected according to specific needs.

[0066] When the adjustable foot 105 is adjusted to be lower than the lowest point of the universal caster 104, the auxiliary device will mainly rely on the adjustable foot 105 to ground. In this mode, the entire device obtains higher stability. This is particularly important for children with cerebral palsy who have poor balance or are just starting to learn to use the auxiliary device. The fixed support point can provide stronger security, which helps to establish the user's confidence. In addition, this mode is also suitable for use in some special ground environments, such as slightly uneven ground, and the adjustable foot 105 can provide better adaptability.

[0067] Conversely, when the adjustable leg 105 is adjusted to be higher than the lowest point of the caster 104, the auxiliary device will mainly rely on the caster 104 to land. In this mode, the whole device obtains higher flexibility and maneuverability. This mode is more suitable for children with cerebral palsy who are already familiar with the use of the auxiliary device and want to improve the walking flexibility. The use of the caster 104 makes it easier to turn and adjust the direction, which is beneficial to improve the independence and autonomous walking ability of the user.

[0068] Therefore, the design of the adjustable leg 105 embodies the humanization and individualization of the device, allowing the functions of the auxiliary device to be adjusted according to the specific circumstances and needs of each user. For example, during different stages of rehabilitation training, it can gradually transition from using the adjustable leg 105 to using the caster 104, and this gradual adjustment helps children with cerebral palsy gradually improve their balance and walking skills.

[0069] In some embodiments of the present application, the caster 104 is configured to be elastically floating in the up-down direction, so that the caster 104 is pressed downward and then floats upward, and the adjustable leg 105 is in contact with the ground.

[0070] In this embodiment, the caster 104 can elastically float and compress upward when subjected to pressure. Under the action of the user's body weight, the caster 104 can automatically float upward, so that the adjustable leg 105 is in contact with the ground. Therefore, when the child with cerebral palsy lies on the support plate 30 or the body weight acts on the auxiliary device, the body weight is evenly distributed to the whole chassis 10. This weight distribution will generate a downward pressure on the caster 104. Under the action of this pressure, the caster 104 floats upward, and the adjustable leg 105, which is originally slightly above the ground, gradually contacts the ground and eventually bears part of the supporting role. At this time, the fixed leg 103, the adjustable leg 105 and the caster 104 are all in contact with the ground, ensuring that the whole chassis 10 is more stable on the ground, ensuring that the child with cerebral palsy remains stable when lying on the support plate 30, and the whole device remains stable on the ground, thereby ensuring its stability and safety. When the user leaves the support plate 30 or the weight acting on the device decreases, the caster 104 returns to the recovery deformation, and the adjustable leg 105 re-leaves the ground. At this time, the fixed leg 103 and the caster 104 provide support points, which is more conducive to the movement of the device and is beneficial to walking.

[0071] With the above design, the device can have its own support and walking convenience in the two states of temporary rest and walking, so that the user has better adaptation performance in different states, and the user experience is improved.

[0072] In an embodiment of the utility model, the chassis 10 includes two side poles 101 and a cross pole 102, the two side poles 101 are oppositely and parallelly arranged in the left-right direction. The front end of each side pole 101 is downwardly bent to form a vertical part 1011, and the fixed supporting leg 103 is arranged on the vertical part 1011; the rear end of each side pole 101 has a horizontal part 1012 extending horizontally backward, and the adjustable supporting leg 105 and the universal wheel 104 are arranged on the horizontal part 1012. The cross pole 102 is connected between the two side poles 101 and located at the front end of the side poles 101, and between the two side poles 101 to define the standing space.

[0073] In the embodiment, the chassis 10 mainly includes two side poles 101 and a cross pole 102, and the cross pole 102 is connected between the two side poles 101, which not only increases the rigidity of the whole structure, but also defines the standing space of the user with the two side poles 101, that is, the structure not only provides the necessary structural stability, but also forms the standing space for the cerebral palsy children to stand and walk conveniently.

[0074] In an embodiment of the utility model, the horizontal part 1012 is provided with a fixed seat 106, the fixed seat 106 is provided with a through hole, the top of the universal wheel 104 is provided with a center column 1041, and the center column 1041 can be slidably sleeved in the through hole. The size of the center column 1041 is matched with the through hole in the fixed seat 106, and the center column 1041 can freely slide in the through hole. The universal wheel 104 is allowed to move in the vertical direction in a controlled manner, so that the elastic floating function is realized.

[0075] The center column 1041 is sleeved with a spring 107, the upper end of the spring 107 abuts against the fixed seat 106, and the lower end of the spring 107 abuts against the top of the universal wheel 104. That is, the spring 107 is between the fixed seat 106 and the universal wheel 104, and the configuration makes the spring 107 be able to compress when the universal wheel 104 is pressed, and push the universal wheel 104 back to the original position after the pressure is released.

[0076] The upper end of the center column 1041 is provided with a nut 108, and the nut 108 is stopped above the fixed seat 106. The spring 107 is a key element for realizing the elastic floating. The nut 108 plays a role of stopping, which is fixed on the center column 1041 and located above the fixed seat 106. In this way, not only the movement range of the universal wheel 104 is limited, but also the universal wheel 104 is prevented from being separated.

[0077] In this embodiment, the floating structure design allows the universal caster 104 to be compressed upward when bearing weight, so that the adjustable leg 105 can contact the ground, increasing the stability of the entire device. When the weight is reduced, the spring 107 can push the universal caster 104 back to its original position, restoring its flexibility. The presence of the nut 108 ensures the safety and reliability of the entire structure.

[0078] Preferably, the fixed seat 106 is also provided with a guide hole, and the top of the universal caster 104 is provided with a guide column 1042 which is in sliding fit with the guide hole. In this way, the guide fit of the guide column 1042 and the guide hole is utilized to ensure that the universal caster 104 floats up and down more stably and reliably.

[0079] In an embodiment of the present application, the fixed seat 106 includes a sleeve 1061 and an ear seat 1062. The sleeve 1061 is sleeved on the horizontal part 1012 and fixed thereto by bolts. The ear seat 1062 protrudes radially outward from the outer peripheral wall of the sleeve 1061, and the through hole and the guide hole are provided on the ear seat 1062. In this way, the sleeve 1061 is sleeved and fixed with the horizontal part 1012, facilitating assembly, and the ear seat 1062 facilitates installation of the universal caster 104.

[0080] In an embodiment of the present application, the horizontal part 1012 has a threaded cylinder 1013 extending in the up-down direction, and the upper end of the adjustable leg 105 is in threaded fit with the threaded cylinder 1013. In this way, when it is necessary to adjust the height of the adjustable leg 105, it is only necessary to rotate the adjustable leg 105, which is simple and convenient to operate.

[0081] In an embodiment of the present application, the two ends of the supporting plate 30 are respectively provided with a sliding sleeve 301, and the sliding sleeve 301 is provided with a positioning hole. The handrail rod 20 is provided with a plurality of elastic buckles 201, and the plurality of elastic buckles 201 are arranged in the up-down direction at intervals, and each elastic buckle 201 can be positioned and matched with the positioning hole.

[0082] In this embodiment, each elastic buckle 201 can be positioned and matched with the positioning hole, and this matching mode is simple and reliable. When it is necessary to adjust the height of the supporting plate 30, it is only necessary to press the elastic buckle 201 slightly to make it disengage from the positioning hole, then slide the supporting plate 30 up and down to the desired position, and then make the elastic buckle 201 match with the positioning hole at the new position. This operation is simple and intuitive, can realize quick and accurate height adjustment, and at the same time ensures the stability and safety after adjustment.
