Description

TECHNICAL FIELD

[0001] The utility model relates to physiotherapy auxiliary tool technical field especially, relates to a folding walking aid. BACKGROUND

[0002] The walking aid is also called lower limb orthosis, which is a walking support tool for the elderly, patients and disabled people who have difficulty in walking. Users can easily walk by holding the walking aid, and they can maintain body balance, support body weight, train walking and enhance muscle strength by using the walking aid.

[0003] The existing walking aid is usually composed of left and right supports, a front support and legs connected with each other, and can be folded for storage and transportation. For example, the Chinese utility model patent with the patent name "a telescopic folding walking aid" and the publication number CN217525726U discloses a left support, a right support, a connecting front support, a left front support, a right front support, a telescopic mechanism and a folding mechanism. When the user needs to adjust the distance between the left and right supports, the total length between the left and right front supports is adjusted by the telescopic mechanism to adjust the distance between the left and right supports to adapt to the needs of different users. When transportation is needed, the left and right supports are folded inward by the folding mechanism to reduce the overall volume of the walking aid for easy transportation.

[0004] However, the existing technology still has the following defects:

[0005] 1. The overall width of the existing walking aid after folding the left and right supports usually reaches 1.1 times the width of the support. In addition, after disassembling and folding the legs onto the left and right supports, the overall thickness reaches 3 to 4 times the thickness of the side tube, so the folding area occupies a large space and the transportation cost is high.

[0006] 2. The left and right supports of the walking aid are connected through the sleeve of the front bar, and when unfolded for use, the front bar and the support will be worn out after a long time of use, resulting in assembly play and metal collision noise.

[0007] 3. When adjusting the height of the left and right supports of the existing walking aid, either the height of the left and right supports cannot be adjusted independently, or when adjusting the height of the left and right supports, the overall posture of the walking aid will be tilted, so the height adjustment structure of this walking aid cannot be used by people with disabilities such as long and short arms, and lacks humanized design.

[0008] 4. The assembly gap between the positioning hole and the positioning rod of the walking aid will become larger and larger, and the positioning rod will collide with the positioning hole during use, producing metal collision noise and causing noise disturbance to family members and neighbors.

Therefore, the overall width of the folded walker is consistent with that in the unfolded state, and more space is saved compared with the prior art folding width of 1.1 times the width of the side frame. Moreover, the supporting legs of the walker can be detachably inserted between the front and rear side tube feet in a staggered manner, and the height of the folded walker is reduced by at least one third. In addition, the overall thickness of the folded walker is 2 times the thickness of the side tube, which greatly saves space compared with the prior art folding method in which the overall thickness is 3-4 times the thickness of the side tube, thereby saving transportation volume and at least 40% of transportation costs.

[0027] (2) The locking structure provided by the embodiment of the application can make the slide rod on the rotating cover slide in the lock groove and drive the lock arm to swing outward to lock the unfolded state of the front bar plate or drive the lock arm to swing inward to unlock the unfolded state of the front bar plate by only rotating the rotating cover clockwise or counterclockwise by hand. In this way, the switching convenience of the left frame assembly and the right frame assembly of the walker between the unfolded and folded states is improved, and the user only needs to rotate the rotating cover of the locking structure clockwise or counterclockwise by hand, which is simple to operate and improves the user experience.

[0028] (3) The elastic pressing structure provided by the embodiment of the application is elastically connected to the elastic pressing seat, and under the elastic action, the elastic pressing end of the elastic pressing arm always keeps the sleeve of the front bar plate and the front side tube foot, so that the assembly of the front bar plate and the front side tube foot is more stable, thereby preventing the problem of metal collision noise between the sleeve of the front bar plate and the front side tube foot due to virtual position.

[0029] (4) The left frame assembly and the right frame assembly provided by the embodiment of the application are respectively provided with lifting adjustment mechanisms. The lifting adjustment mechanisms are provided with positioning buttons, which control the positioning members to be inserted into or withdrawn from the positioning holes provided in the support frame and the supporting legs, thereby realizing the locking or loosening of the connection state between the support frame and the supporting legs. Since the left frame assembly and the right frame assembly are fixedly connected to each other through the supporting legs, the height of each side frame on the upper part of the left frame assembly and the right frame assembly can be independently adjusted by the positioning buttons, and the overall balance of the walker can be maintained. Compared with the prior art in which the left and right side frames are fixedly connected and the height of the left and right side frames needs to be adjusted simultaneously, the use is more convenient and flexible, and can be used by special groups such as people with long or short arms, which is a humanized design.

[0030] (5) The mute assembly provided by the embodiment of the application is provided with an elastic strip, so that the pin foot and the supporting leg are elastically connected through the elastic strip. Even if the assembly gap between the positioning hole and the positioning piece increases due to wear with the use time, since the positioning piece is arranged on the supporting leg through the cross support and the positioning hole is arranged on the pin foot, the positioning piece and the positioning hole are always in close contact when the supporting leg and the pin foot are elastically pulled towards each other.

[0052] In the following, the utility model is further described in combination with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.

[0053] First embodiment

[0054] As Figures 1-10As shown, a folding walking aid includes a left side frame assembly 10, a right side frame assembly 11, a front pole assembly 20, a lifting adjustment assembly, a mute assembly 60, a locking structure 30 and a springing structure 40, wherein the left side frame assembly 10 and the right side frame assembly 11 are respectively provided with a support frame, a front side leg 131 and a rear side leg 132, the upper part of the support frame is provided with a hand holding part 123 for a user to hold, and the lower part of the support frame is provided with a front side tube foot part 121 and a rear side tube foot part 122. Moreover, the front side leg 131 is detachably sleeved on the front side tube foot part 121, and the rear side leg 132 is detachably sleeved on the rear side tube foot part 122. By adjusting the relative connection position of the tube foot part and the leg, the height of the side frame of the walking aid is adjusted.

[0055] In the embodiment of the present application, a hollow cross support 70 is arranged between the front side leg 131 and the rear side leg 132, the front side leg 131 and the rear side leg 132 are fixedly connected together through the cross support 70, and the cross support 70 plays a role of strengthening the structural strength of the side frame assembly.

[0056] The front pole assembly 20 is provided with a front pole plate 201, and the front pole plate 201 is provided with two pieces in the embodiment of the present application. The two pieces of the front pole plate 201 are hingedly connected to each other, and a folding part 2011 is formed between the two pieces of the front pole plate 201. Preferably, the folding part 2011 is arranged at the middle position of the two pieces of the front pole plate 201, so that the two pieces of the front pole plate 201 can be folded together by half.

[0057] The other end of the two pieces of the front pole plate 201 is respectively provided with a sleeve 202, and the front side tube foot part 121 of the left side frame assembly 10 and the right side frame assembly 11 is arranged in a straight tube shape. Therefore, the front side tube foot part 121 is arranged in a straight tube shape, so as to facilitate the sleeving of the sleeve 202 of the front pole plate 201. The other end (for example, the left end of the left front pole plate 201 and the right end of the right front pole plate 201) of the two pieces of the front pole plate 201 is respectively movably sleeved on the front side tube foot part 121 of the left side frame assembly 10 and the right side frame assembly 11 through the sleeve 202.

[0058] In the prior art, the front pole plate 201 is sleeved on the closed loop structure of the left side frame assembly 10 and the right side frame assembly 11 through the sleeves 202 at both ends, which is not convenient for laser welding. After the front pole plate 201 is assembled on the left side frame assembly 10 and the right side frame assembly 11, the processing operation of laser welding and oxidation treatment is not complete, and the oxidation effect is poor. In the embodiment of the present application, the front side tube foot part 121 is arranged in a straight tube shape, so that the front pole can be directly sleeved and installed at any time. The laser welding and oxidation treatment of the left and right side frames can be flexibly arranged, and the production and processing efficiency of the walking aid is improved.

[0059] In use, the left side frame assembly 10 and the right side frame assembly 11 are stacked facing each other when folded along the folding part 2011 by the two front bumper plates 201, or the left side frame assembly 10 and the right side frame assembly 11 are unfolded in opposite directions when opened along the folding part 2011 by the two front bumper plates 201, thereby realizing the purpose of arbitrarily switching between the folded and unfolded states of the left side frame assembly 10 and the right side frame assembly 11 by the front bumper plates 201.

[0060] In this way, a foldable front bumper 201 is provided between the left side frame assembly 10 and the right side frame assembly 11 of the walker. When the front bumper 201 is folded along the folding part 2011, the left side frame assembly 10 and the right side frame assembly 11 can be stacked facing each other. Therefore, the overall width of the walker in the folded state is the same as that in the unfolded state, which saves more space compared to the previous implementation method where the folded width is 1.1 times the width of the side frame. Moreover, the outriggers of the walker can be detached and staggered and inserted between the front and rear side tube feet 122. The height of the walker in the folded state is reduced by at least one-third. In addition, the overall thickness of the walker in the folded state is twice the thickness of the side tubes. Compared to the previous implementation method where the overall thickness after folding is 3-4 times the thickness of the side tubes, it saves a lot of space and transportation volume, and saves at least 40% of transportation costs.

[0061] The locking structure 30 includes a rotating cover 301, a lock seat 302, and a lock arm 303. The lock seat 302 is disposed on the folded portion 2011 of the two front bumper plates 201. The lock arm 303 has a connecting end, a tightening end, and a lock groove disposed between its connecting end and tightening end. The connecting end of the lock arm 303 is movably connected to the lock seat 302, and the tightening end of the lock arm 303 is used to tighten or loosen the two front bumper plates 201. The rotating cover 301 is movably connected to the folded portion 2011 of the front bumper plate 201 and is rotatably disposed above the lock seat 302. The bottom of the rotating cover 301 has a slide rod that slides in cooperation with the lock groove of the lock arm 303.

[0062] like Figure 6 As shown, when the rotating cover 301 is rotated clockwise, the slide bar of the rotating cover 301 slides in the locking groove and drives the locking arm 303 to swing outward, thereby locking the front bumper 201 in the unfolded state and maintaining the unfolded state of both front bumper 201; Figures 7-8 As shown, when the rotating cover 301 is rotated counterclockwise, the slide bar of the rotating cover 301 slides in the locking groove and drives the locking arm 303 to swing inward, unlocking the front bumper 201 into its unfolded state. The two front bumper panels 201 can then be folded in half. This improves the ease of switching between the unfolded and folded states of the left frame assembly 10 and the right frame assembly 11 of the walker. Users only need to rotate the rotating cover 301 of the locking structure 30 clockwise or counterclockwise by hand, making the operation simple and improving the user experience.

[0063] likeFigures 2-3 As shown, the elastic pressing structure 40 has an elastic pressing base 401, an elastic pressing arm 402 and a spring 403. The elastic pressing base 401 is fixedly arranged on the front side foot portion 121 of the left side frame assembly 10 or the right side frame assembly 11. The elastic pressing arm 402 has an elastic pressing end and a hand moving end. The elastic pressing end and the hand moving end of the elastic pressing arm 402 are rotatably connected to the elastic pressing base 401 through a rotating shaft. The spring 403 is sleeved on the rotating shaft. The spring 403 applies an elastic force to the elastic pressing arm 402. Under the elastic force of the spring 403, the elastic pressing end of the elastic pressing arm 402 always presses the sleeve pipe 202 of the front pipe plate 201 and the front side foot portion 121, so that the assembly of the front pipe plate 201 and the front side foot portion 121 is more stable. In this way, the problem of metal collision noise between the sleeve pipe 202 of the front pipe plate 201 and the front side foot portion 121 due to the virtual position is prevented.

[0064] In addition, when it is needed to release the elastic pressing state of the elastic pressing arm 402 and the front pipe plate 201, the hand moving end of the elastic pressing arm 402 is moved by hand, so that the elastic pressing end is separated from the front pipe plate 201. When the walker is folded, the elastic pressing state of the elastic pressing arm 402 and the front pipe plate 201 also needs to be released.

[0065] The lifting adjusting mechanism 50 has a positioning button 503, a positioning piece 501, a first sliding block 505, a second sliding block 506, a connecting rod 502 and an elastic reset piece. The cross support 70 is an inner hollow structure. The cross support 70 is provided with a button assembly hole. The positioning button 503 is mounted on the cross support 70 through a button cover. The positioning button 503 has two downward extending connecting shaft arms. The two connecting shaft arms are provided with guide shafts 5031.

[0066] The cross support 70 is provided with two guide sliding seats 504 corresponding to the position of the positioning button 503. The guide sliding seat 504 has a first guide groove and a second guide groove. The first guide groove extends in the direction of the height adjustment locking of the side frame. The second guide groove extends in the pressing direction of the positioning button 503. Therefore, the first sliding block 505 and the second sliding block 506 are correspondingly and slidably mounted in the first guide grooves of the two guide sliding seats 504. The first sliding block 505 and the second sliding block 506 are in a staggered sliding assembly relationship. The connecting shaft arms of the positioning button 503 are movably mounted in the second guide grooves. In this way, the assembly of the positioning button 503, the first sliding block 505 and the second sliding block 506 on the cross support 70 is realized through the guide sliding seat 504.

[0067] The first slider 505 and the second slider 506 are respectively provided with guide grooves, and the guide grooves of the first slider 505 and the second slider 506 are respectively arranged obliquely downward in the respective elastic reverse reset directions, so that the guide grooves of the first slider 505 and the second slider 506 are arranged in a substantially "eight" shape relative to each other. The two connecting shaft arms of the positioning button 503 extend in the direction of the guide grooves, so that the guide shafts 5031 on the two connecting shaft arms are respectively correspondingly in sliding fit with the guide grooves on the first slider 505 and the second slider 506.

[0068] Moreover, the reverse sliding ends of the first slider 505 and the second slider 506 are connected to the positioning member 501 through the connecting rod 502, so that the first slider 505 and the second slider 506 can drive the positioning member 501 through the connecting rod 502. In addition, the opposite sliding ends of the first slider 505 and the second slider 506 are connected to the elastic reset members for applying reverse sliding elastic force, so that after the positioning button 503 is released, the first slider 505 and the second slider 506 can be reversely reset and slid under the elastic action of the elastic reset members.

[0069] The front side pin portion 121 and the rear side pin portion 122 are provided with a plurality of positioning holes 14 in the length direction, and the front side leg 131 and the rear side leg 132 are provided with holes for the positioning member 501 to pass through at the connection with the cross support 70. When the pin portion and the leg are installed, the positioning member 501 on the front side leg 131 and the cross support 70 is correspondingly inserted into the positioning hole 14 on the front side pin portion 121, so as to lock the assembly position between the front side leg 131 and the front side pin portion 121. The positioning member 501 on the rear side leg 132 and the cross support 70 is correspondingly inserted into the positioning hole 14 on the rear side pin portion 122, so as to lock the assembly position between the rear side leg 132 and the rear side pin portion 122.

[0070] In this way, the side frame height of the left side frame assembly 10 and the right side frame assembly 11 of the walking aid is adjusted, and the lifting adjusting mechanism 50 is arranged on the cross support 70 of the leg, so that the user can also adjust the side frame height with hands when using the walking aid. Compared with the previous implementation means of bending down to press the positioning member 501 to adjust the side frame height, the convenience and flexibility of the walking aid of the embodiment of the application are higher.

[0071] According to the above description, the cross brace 70 is fixedly connected between the front side leg 131 and the rear side leg 132, and when the positioning member 501 is installed, a limiting seat 701 is arranged on each of the two ends of the cross brace 70 connected with the front side leg 131 and the rear side leg 132, a through hole is formed in the limiting seat 701 and communicates with the through hole on the leg and the pipe foot, and the positioning member 501 is slidably arranged in the through hole. Under the control of the positioning button 503, the positioning member 501 can reciprocate in the through hole of the limiting seat 701, and the through hole can guide the positioning member 501 to be accurately inserted into or withdrawn from the positioning hole 14, thereby improving the smoothness of the height adjustment of the side frame of the walking aid.

[0072] Specifically, when the positioning button 503 is pressed, the guide shaft 5031 slides obliquely downward along the guide groove, the first slider 505 and the second slider 506 slide in opposite directions, and the first slider 505 and the second slider 506 respectively drive the positioning member 501 to exit the positioning hole 14 through the connecting rod 502, so as to unlock the connection state of the leg and the pipe foot. At this time, the leg can be pulled to adjust the height of the side frame.

[0073] When the positioning button 503 is released, the first slider 505 and the second slider 506 elastically slide in the reverse direction, the guide shaft 5031 slides obliquely upward along the guide groove, and the first slider 505 and the second slider 506 respectively push the positioning member 501 to insert into the positioning hole 14 through the connecting rod 502, so as to lock the connection state of the leg and the pipe foot. At this time, the leg cannot be adjusted.

[0074] In this way, the left side frame assembly 10 and the right side frame assembly 11 are respectively provided with the lifting adjustment mechanism 50, the positioning button 503 is arranged on the lifting adjustment mechanism 50, the positioning member 501 is controlled to insert into or exit the positioning hole 14 arranged on the support frame and the leg, and then the connection state between the support frame and the leg is locked or released. By pressing the positioning button 503, the height of the side frame of the left side frame assembly 10 and the right side frame assembly 11 can be adjusted, which is simple and convenient to operate.

[0075] The mute assembly 60 has an elastic strip 601 and quick release heads arranged at both ends of the elastic strip 601. The elastic strip 601 used in the embodiment of the application can be an elastic band or a telescopic spring 403.

[0076] When installing the elastic strip 601, the first end of the elastic strip 601 is threaded along the tube hole of the front side foot part 121, the hand holding part 123 and the rear side foot part 122 until the first end of the elastic strip 601 is connected to one end of the rear side leg 132 connected by the cross brace 70. Since the quick release holes are provided on both ends of the cross brace 70, the quick release heads at both ends of the elastic strip 601 can be detachably and quickly connected to the limiting seat 701 inside the cross brace 70. In addition, the quick release head of the second end of the elastic strip 601 is connected to one end of the front side leg 131 connected by the cross brace 70.

[0077] Since the cross brace 70 is fixedly connected to the front side leg 131 and the rear side leg 132, when the cross brace 70 is tensioned by the elastic strip 601, that is, the front side leg 131 and the rear side leg 132 are tensioned, the front side foot part 121 and the front side leg 131, and the rear side foot part 122 and the rear side leg 132 always maintain an elastic tensioning state towards each other.

[0078] In this way, the mute assembly 60 is provided with the elastic strip 601, so that the foot part and the leg are elastically connected by the elastic strip 601. Even if the assembly gap between the positioning hole 14 and the positioning piece 501 increases due to wear over time, since the positioning piece 501 is provided on the leg by the cross brace 70, and the positioning hole 14 is provided on the foot part, when the leg and the foot part are elastically tensioned towards each other by the elastic strip 601, the positioning piece 501 and the positioning hole 14 are always in close contact regardless of whether the user is lifting or lowering the walker. Thus, the problem of metal collision noise caused by the positioning rod colliding with the positioning hole 14 during use is avoided, the mute use effect of the walker is improved, and the user experience is improved.

[0079] Second embodiment

[0080] As shown in Figures 11-13 The difference between the embodiments of the application and the first embodiment is that the positions of the elastic pressing structure 40 and the front lever plate 201 are different. The rest are the same and will not be repeated here.

[0081] Specifically, since the other end of the two front lever plates 201 is provided with a sleeve 202, and the front side leg 131 is provided in a straight tube shape, the front lever plate 201 can be sleeved on the front side leg 131 of the left side frame assembly 10 and the right side frame assembly 11 through the sleeve 202, thereby connecting the front side legs 131 of the left side frame assembly 10 and the right side frame assembly 11 together, and improving the overall structural stability of the walker.

[0082] In this embodiment, since the legs of the left side frame assembly 10 and the right side frame assembly 11 are not connected, the height of each side frame can be independently adjusted by operating the lifting adjustment mechanism 50. Adjusting the height of either the left or right side frame assembly 10 does not affect the height of the other side, maintaining the overall balance of the walker and ensuring normal and safe use by the user. This is particularly suitable for people with different arm lengths, demonstrating a user-friendly design. Compared to previous walkers where the left and right side frames were fixedly connected and required simultaneous adjustment of both side frame heights, this method offers greater convenience and flexibility, and is suitable for people with different arm lengths, reflecting a user-friendly design.

[0083] At this time, the front bumper 201 is located below the cross brace 70 of the outrigger, so the spring-loaded structure 40 can be set on the cross brace 70, the spring-loaded seat 401 can be slidably set inside the cross brace 70, and the spring-loaded arm 402 is set below the cross brace 70. The spring-loaded arm 402 passes through the cross brace 70 via a pivot and is elastically connected to the spring-loaded seat 401. Under the elastic action, the spring-loaded arm 402 can also achieve the same result: the spring-loaded end of the spring-loaded arm 402 always keeps the sleeve 202 that fits between the front bumper 201 and the front side tube 121, making the assembly of the front bumper 201 and the front side tube 121 more stable and preventing the problem of metal collision noise caused by play between the sleeve 202 of the front bumper 201 and the front side tube 121. Furthermore, by movably setting the spring-loaded seat 401 within the cross brace 70, the spring-loaded seat 401 can be installed at any position along the length of the cross brace 70. When the spring-loaded arm 402 wears out after prolonged use, the position of the spring-loaded seat 401 can be adjusted to solve the problem of insufficient spring-loaded fastening of the front bumper 201 due to wear of the spring-loaded arm 402.

[0084] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
