Abstract
Description
Technical Field
[0001] The utility model relates to a walking aid, in particular to a walking aid for rehabilitation training of patients with cerebral infarction and the like, and belongs to the field of rehabilitation medical equipment. Background Art
[0002] Rehabilitation training refers to physical activities that are beneficial to the recovery or improvement of function after an injury. Except for severe injuries that require rest and treatment, general injuries do not require complete cessation of physical exercises. Appropriate and scientific physical exercises play a positive role in the rapid healing of injuries and the promotion of functional recovery. Walkers are often used in rehabilitation training. Walkers, also called lower limb orthoses, are a walking support tool for the elderly with limited mobility, certain traumatic injuries, hemiplegic patients, and the disabled to help them walk or exercise their limbs. People can walk slowly and easily with the help of it.
[0003] Walkers help patients recover quickly and enhance the possibility of short-distance movement. They are widely used in homes, hospitals and rehabilitation institutions. They are very useful and effective tools for patients who need rehabilitation training. Walkers can provide effective support for patients, help them maintain balance and walk, and prevent patients from falling during rehabilitation walking training.
[0004] During rehabilitation walking training, patients need to rest after a certain period of training due to lack of physical strength. Most existing walkers usually do not have the function of allowing patients to sit down and rest. When they need to rest during rehabilitation walking training, they can only stand and rest with the help of the walker, or move a chair to sit aside to rest. The chair requires another accompanying person to move back and forth, which increases the workload and labor intensity of the accompanying person, reduces the practicality of the device, and cannot meet the use requirements. Some walkers are equipped with a fixed seat board inside the walker, and the patient can sit on the seat board to rest when he needs to rest. However, since the seat board is fixed inside the walker, space for the patient to walk needs to be reserved in the walker. When the patient walks, the patient's legs will often contact and collide with the seat board, making it extremely inconvenient for the patient to walk. In addition, the patient needs to turn 180 degrees in the process of switching between the sitting down state and the standing up and walking state, which is undoubtedly a difficult process for patients undergoing rehabilitation training, and they may even fall if they are not careful. In addition, during the rehabilitation training, the user has difficulty walking and controlling his or her posture. At the same time, because there are no supporting parts on both sides of the walker, the user is prone to tilting and falling together with the walker during the rehabilitation walking process. Summary of the invention
[0005] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a walking aid.
[0006] The technical solution adopted by the utility model is: designing a walker, including two handrail frames and a front connecting rod and an upper connecting rod for connecting the two handrail frames, which also includes a multifunctional side bracket and a latch. The multifunctional side brackets are respectively arranged on the sides of the two handrail frames that are separated from each other, and the multifunctional side brackets are slidably connected with the handrail frames and locked by the latches. The multifunctional side brackets can be pulled out of the handrail frames backwards or overlapped with the handrail frames and locked by the latches. The multifunctional side brackets include a resting platform at the upper end and an anti-rollover platform at the lower end that is in the same horizontal plane as the lower end of the handrail frames.
[0007] Furthermore, the multifunctional side bracket of the present design includes an integrated frame and supporting legs, a plurality of supporting legs are arranged in an array under the integrated frame, the upper ends of the integrated frame and all supporting legs constitute a resting platform, and the lower ends of all supporting legs constitute an anti-roll platform.
[0008] Furthermore, the integrated frame of the present design is a rectangular frame assembled from round tubes, and the supporting legs are Z-shaped legs assembled from round tubes.
[0009] Furthermore, the upper and lower parts of the support legs described in the present design are respectively provided with reinforcing rods.
[0010] Furthermore, the present design also includes a sliding assembly, which includes a sliding rail member and a sliding block member. The sliding rail member is arranged on the side of the armrest frame, and the sliding block member is installed on the multifunctional side bracket. The sliding rail member and the sliding block member are slidably connected, and a first locking hole is arranged at the rear end of the sliding rail member, and second locking holes matching the first locking hole are respectively arranged at the front and rear ends of the sliding block member.
[0011] Furthermore, the slide rail member described in the present design includes a first rectangular tube, a rectangular opening is opened on a side of the first rectangular tube close to the multifunctional side bracket, and the rectangular opening passes through the rear end of the slide rail member. The sliding block member includes a second rectangular tube and a connecting strip, and the second rectangular tube is installed on a side of the multifunctional side bracket close to the slide rail member through the connecting strip. The sliding block member is inserted into the slide rail member and can slide back and forth along the slide rail member.
[0012] Furthermore, the first locking hole provided at the rear end of the slide rail member in the present design is at least 3 cm away from the rear end of the slide rail member.
[0013] Furthermore, the handrail frame described in the present design is provided with handrail legs on the front and rear sides respectively, a reinforcing connecting rod is provided between the two handrail legs, and the multifunctional toilet bracket is provided at the reinforcing connecting rod.
[0014] Furthermore, the lower part of the armrest leg and the lower part of the supporting leg described in the present design are respectively configured as sleeve-type structures with adjustable heights.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] Through the setting of the multifunctional side bracket, it can be pulled out as a resting stool for patients to rest, which can better meet the use requirements. And the multifunctional side bracket is set on the outside of the walker (armrest), which does not affect the space for patients to walk in the walker. When the patient is walking, the patient's legs will not contact and collide with it, which is more convenient and practical. In addition, the multifunctional side bracket is set on the left and right sides of the walker (armrest). The patient only needs to turn sideways 90° when switching between the sitting down and resting state and the standing up and walking state, which can reduce the difficulty of use for rehabilitation training patients and reduce the occurrence of falls. Finally, when the patient uses the walker for rehabilitation training, the multifunctional side bracket overlaps with the armrest. During the rehabilitation training process, the multifunctional side bracket can effectively prevent the walker from tipping to the left and right sides, improve the stability of the walker during use, avoid the patient's unstable center of gravity and fall, and further reduce the occurrence of patient falls.

[0025] Example 1
[0026] like Figure 1-Figure 4 As shown: a walker, including two handrail frames 1 and a front connecting rod 2 and an upper connecting rod 3 for connecting the two handrail frames 1, which also includes a multifunctional side bracket 4 and a latch 5. A multifunctional side bracket 4 is respectively arranged on the side of the two handrail frames 1 that are away from each other, and the multifunctional side bracket 4 is slidably connected to the handrail frame 1 (and can only slide relative to each other forward and backward, and cannot rotate) and is locked by the latch 5. The multifunctional side bracket 4 can be pulled out of the handrail frame 1 backward or overlapped with the handrail frame 1 and then locked by the latch 5. The multifunctional side bracket 4 includes a rest platform at the upper end and an anti-roll platform at the lower end that is in the same horizontal plane as the lower end of the handrail frame 1. When the multifunctional side bracket 4 is pulled out of the armrest frame 1 backwards, it is locked by the latch 5, so that the front end of the multifunctional side bracket 4 is fixed to the rear end of the armrest frame 1, and the rest platform at the upper end of the multifunctional side bracket 4 can be used as a stool for the patient to sit down and rest temporarily; when the multifunctional side bracket 4 is overlapped with the armrest frame 1, it is locked by the latch 5, so that the rear end of the multifunctional side bracket 4 is fixed to the rear end of the armrest frame 1, and the anti-roll platform at the same horizontal plane as the lower end of the multifunctional side bracket 4 can prevent the walker from tipping to the left or right during the patient's walking (the anti-roll platform has a longer force arm at this time).
[0027] Example 2
[0028] like Figure 4 As shown: This embodiment further optimizes and refines the structure of the multifunctional side bracket 4 on the basis of Embodiment 1, specifically:
[0029] The walker described in this embodiment, its multifunctional side bracket 4 includes an integrated frame 6 and support legs 7. A plurality of support legs 7 are arranged in an array under the integrated frame 6, and all the support legs 7 are arranged in a row front to back along the integrated frame 6. The upper ends of the integrated frame 6 and all the support legs 7 constitute a resting platform. All the support legs 7 are integrated into an integral structure through the integrated frame 6, and the lower ends of all the support legs 7 constitute an anti-roll platform. Soft cushions (not shown in the drawings) can also be nested in the integrated frame 6 to improve the patient's sitting comfort.
[0030] The multifunctional side bracket 4 can also adopt another structural form (not shown in the drawings): instead of using the integrated frame 6, front and rear longitudinal connecting rods are directly set between the supporting legs 7, and all the supporting legs 7 are connected to each other through the connecting rods to form an integral structure, which is more simple in structure.
[0031] Example 3
[0032] This embodiment further optimizes and refines the structure of the multifunctional side bracket 4 on the basis of Embodiment 2, specifically:
[0033] The integration frame 6 is a rectangular frame assembled from round tubes, and the support legs 7 are Z-shaped legs assembled from round tubes, which are easy to obtain and manufacture, and correspond to the pipe materials used in structures such as the handrail frame 1, which is more beautiful.
[0034] Example 4
[0035] This embodiment further optimizes and refines the structure of the multifunctional side bracket 4 on the basis of Embodiment 3, specifically:
[0036] The upper and lower parts of the support leg 7 are respectively provided with reinforcing rods 8 to improve the bearing capacity and anti-deformation strength of the support leg 7. The two reinforcing rods 8 can be independent rods, which is convenient for setting the support leg 7 into a sleeve structure with adjustable height (see below). The two reinforcing rods 8 on the same support leg 7 can also be an integrated structure, directly passing through the upper part of the support leg 7 to the lower part. This structure can greatly improve the bearing capacity of the support leg 7, but the support leg 7 can no longer be set into a height-adjustable structure. Accordingly, the height of the handrail frame 1 must also be fixed.
[0037] Example 5
[0038] This embodiment further optimizes and refines the structure of the walker based on the embodiment 4, specifically:
[0039] The walker described in this embodiment also includes a sliding assembly, which includes a slide rail 9 and a slider 10. The slide rail 9 is arranged on the side of the handrail frame 1 (it can be fixed by welding or screws), and the slider 10 is installed on the multifunctional side bracket 4. The slide rail 9 and the slider 10 are slidably connected, that is, the multifunctional side bracket 4 can slide forward and backward along the handrail frame 1. The rear end of the slide rail 9 is provided with a first locking hole 11, and the front and rear ends of the slider 10 are respectively provided with second locking holes 12 that match the first locking hole 11. When the multifunctional side bracket 4 is pulled out of the handrail frame 1 backward as a resting stool, the second locking hole 12 at the front end of the slider 10 is aligned with the first locking hole 11 at the rear end of the slide rail 9, and the latch 5 is inserted to lock the multifunctional side bracket 4; when the multifunctional side bracket 4 is overlapped with the handrail frame 1 and used as an anti-rollover structure, the second locking hole 12 at the rear end of the slider 10 is aligned with the first locking hole 11 at the rear end of the slide rail 9, and the latch 5 is inserted to lock the multifunctional side bracket 4. The latch 5 can be fastened to the handrail frame 1 with a steel rope. The first locking hole 11 and the second locking hole 12 are through holes that penetrate the slide rail member 9 and the slider member 10 respectively. One of the first locking hole 11 and the second locking hole 12 can also be set as a threaded hole, and a corresponding external thread can be set on the latch 5 to improve the connection stability of the latch 5.
[0040] Example 6
[0041] This embodiment further optimizes and refines the sliding connection structure on the walker based on the embodiment 5, specifically:
[0042] The slide rail member 9 includes a first rectangular tube, and a rectangular opening is provided on a side of the first rectangular tube close to the multifunctional side bracket 4. The rectangular opening passes through the rear end of the slide rail member 9, but not through the front end of the slide rail member 9, so as to limit the multifunctional side bracket 4 when sliding forward, and prevent the multifunctional side bracket 4 from sliding forward excessively. The slider member 10 includes a second rectangular tube and a connecting strip, and the second rectangular tube fits with the inner cavity of the first rectangular tube, and the connecting strip fits with the rectangular opening on the first rectangular tube. The second rectangular tube is installed on a side of the multifunctional side bracket 4 close to the slide rail member 9 through the connecting strip, and can be welded. The slider member 10 is inserted into the slide rail member 9 and can slide forward and backward along the slide rail member 9. The sliding connection structure is set by the rectangular tube and the rectangular connecting strip, and the structure and manufacturing are simple, the cost is low, and the connection and sliding are smooth and reliable.
[0043] Example 7
[0044] This embodiment is a further optimization and refinement of the sliding connection structure on the walker based on the embodiment 6, specifically:
[0045] The first locking hole 11 arranged at the rear end of the slide rail member 9 is at least 3 cm away from the rear end of the slide rail member 9, and the best length is 4 to 5 cm, to prevent it from being easily deformed or damaged, and to prevent the multifunctional side bracket 4 from being accidentally directly detached from the handrail frame 1 during the process of aligning the second locking hole 12 at the front end of the slider member 10 and the first locking hole 11 on the slide rail member 9 (an anti-detachment structure may also be provided, such as providing a slide groove that does not pass through the front and rear ends of the first rectangular tube on the upper side of the first rectangular tube, and providing an anti-detachment slider on the upper side of the front end of the second rectangular tube, and the anti-detachment slider passes through the slide groove and slides along the slide groove), thereby providing the user with sufficient reaction time and sliding distance, and providing a reliable connection and stop platform for the multifunctional side bracket 4.
[0046] Example 8
[0047] This embodiment further optimizes and refines the structure of the walker based on the embodiment 7, specifically:
[0048] The armrest frame 1 is respectively provided with armrest legs on the front and rear sides, and a reinforcing connecting rod is provided between the two armrest legs. This is a conventional prior art. The armrest leg on the front side of the armrest frame 1 is arranged tilted (forward), and the armrest leg on the rear side is arranged upright or can also be arranged tilted (backward). The multifunctional toilet bracket is arranged at the reinforcing connecting rod to provide sufficiently reliable support for the multifunctional side bracket 4.
[0049] Example 9
[0050] This embodiment further optimizes and refines the structure of the walker on the basis of Embodiment 8, specifically:
[0051] The walker described in this embodiment, the lower part of the armrest leg and the lower part of the support leg 7 are respectively arranged as height-adjustable sleeve-type structures, that is, the lower parts of the two are arranged as sleeves with larger diameters, and the armrest leg and the support leg 7 are respectively formed by plugging two pipes with different inner diameters, and a pressable marble is provided on the pipe with smaller inner diameter, and multiple adjustment holes are opened along the axial direction of the pipe body on the pipe with larger diameter. After the two pipes with different inner diameters are plugged in, the relative height is adjusted by the pressable marbles. This is the prior art and will not be described in detail.
[0052] In addition, a rubber cushion is also provided at the lower part of the armrest leg. In order to facilitate the use of the patient, a walking wheel can be installed on the front or rear armrest leg. An anti-slip armrest cover is also installed on the upper part of the armrest frame 1, such as Figure 3 shown.
[0053] When using the utility model, in the initial state, the multifunctional side bracket 4 is overlapped with the handrail frame 1 and locked by the latch 5, and the patient uses it to walk for rehabilitation training; when the patient feels tired and needs to rest after training for a period of time, he chooses to pull out the latch 5 on one side of the multifunctional side bracket 4 (the patient chooses to use the corresponding multifunctional side bracket 4 according to his own situation, sees which side the patient turns to more conveniently), and then pulls most of the body of the multifunctional side bracket 4 backward out of the range of the handrail frame 1 and locks the multifunctional side bracket 4 by the latch 5, and then the patient only needs to turn 90° and sit sideways to rest. After the rest, the patient stands up and turns 90° to the walking state, puts away the multifunctional side bracket 4, and then continues the rehabilitation training.
[0054] In addition, in the description of the present utility model, unless otherwise specified, if the terms "multiple", "multiple roots", "multiple groups" are used, they mean two or more than two, and "several", "several roots", "several groups" mean one or more than one. In the description of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like are used to indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, it is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.
