Description

Technical Field

[0001] The utility model relates to the technical field of walking aids, in particular to a walking aid with adjustable lateral width. Background Art

[0002] A walker is a tool that provides walking assistance for patients with limited mobility. Because the four corners of a walker touch the ground, its stability is greater than that of crutches and canes. It is more suitable for elderly or weak patients, and the area between the four corners is where the patient moves.

[0003] Most of the currently available walkers can only be adjusted in height longitudinally to meet the needs of patients of different heights. The size of the area for patients to move in the walker is relatively fixed. However, in actual use, patients of different heights also have different body shapes. If the body shape is too large and exceeds the size of the area for patients to move in the walker, the walker cannot meet the needs of such patients.

[0004] Even though there are a small number of walkers with adjustable widths, in general, the width adjustment of the walkers with adjustable widths is achieved through a pull-out adjustment method, such as a double-pull walker for adults and children disclosed in Patent No. CN215081787U, which includes side support frames on both sides and a connecting frame connecting the side support frames on both sides, the side support frames include a side support frame body, a front support seat and a rear support seat, the front support seat and the rear support seat are respectively telescopically connected and arranged at the bottom of the side support frame body, and the height of the double-pull walker for adults and children can be adjusted by adjusting the telescopic degree of the front support seat and the rear support seat; the connecting frame includes an outer connecting frame and an inner connecting frame, the inner connecting frame is telescopically connected and arranged in the outer connecting frame, and the width of the double-pull walker for adults and children can be adjusted by adjusting the telescopic degree of the inner connecting frame in the outer connecting frame.

[0005] Although the walker disclosed in the above application can adjust the width, the inner connecting frame and the outer connecting frame are unlocked and locked by pressing a button, that is, after pressing the button, an external squeezing force is required to achieve the sliding of the inner connecting frame and the outer connecting frame, as well as the sliding of the button.

[0006] When the external extrusion force is applied, the direction of the external extrusion force needs to be kept in the same straight line as the sliding direction between the inner connecting frame and the outer connecting frame. However, the user cannot accurately control the direction of the force when applying the external extrusion force. Once the force is unevenly applied, an offset occurs between the inner connecting frame and the outer connecting frame. After the offset occurs, the button for unlocking may be stuck in the inner cavity of the inner connecting frame, making it difficult to adjust the width. In severe cases, the button may be twisted off.

[0007] In summary, the existing walking aids still have the technical problem that when adjusting the width laterally, the direction of the external squeezing force applied by the user cannot be accurately kept in the same straight line with the direction of the sliding adjustment of the crossbeam, and the button for unlocking may be stuck in the inner cavity of the inner connecting frame, making the width adjustment difficult.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1-3 As shown, a walker with adjustable transverse width comprises two inverted U-shaped rods 1, a plurality of crossbeams 2 connected between the two inverted U-shaped rods 1, and the plurality of crossbeams 2 are sequentially and parallelly distributed between the two inverted U-shaped rods 1 from top to bottom;

[0034] The crossbeam 2 includes a first adjusting rod 21 and a second adjusting rod 22, and the first adjusting rod 21 is slidably inserted in the second adjusting rod 22;

[0035] A locking mechanism 3 is provided at the connection between the first adjustment rod 21 and the second adjustment rod 22 on the cross beam 2 located at the middle position among the multiple cross beams 2;

[0036] The locking mechanism 3 can realize locking or unlocking between the first adjusting rod 21 and the second adjusting rod 22, so as to adjust the distance between the two inverted U-shaped rods 1;

[0037] The crossbeam 2 with the locking mechanism 3 can be stably locked or unlocked under the guidance of the other crossbeams 2 .

[0038] The area between the two inverted U-shaped rods 1 is the place to accommodate the user's torso. For users of different fat or thin sizes, the size of the area between the two inverted U-shaped rods 1 needs to be different, and the two inverted U-shaped rods 1 with adjustable spacing can just meet the adjustment of the area size.

[0039] The device adjusts the distance between the two inverted U-shaped rods 1 by means of a crossbeam with adjustable length. The change in the distance between the two inverted U-shaped rods 1 can satisfy the needs of users of different sizes and has a wide range of applications.

[0040] Specifically, Figure 1-3 As shown, three beams 2 are provided, and a locking mechanism 3 is provided at the connection between the first adjusting rod 21 and the second adjusting rod 22 in one of the middle beams 2. On the one hand, the remaining beams 2 guide the beam 2 at the middle position, thereby ensuring that the direction of the external extrusion force applied by the user can be accurately maintained in the same straight line as the direction of the beam width adjustment, so that the locking mechanism 3 is stably unlocked and locked, achieving the effect of facilitating width adjustment, and on the other hand, it also avoids the possibility of sliding deviation between the first adjusting rod 21 and the second adjusting rod 22.

[0041] Specifically, Figure 1-4 As shown, the inner cavity of the second adjusting rod 22 is provided with a slot 23 for the first adjusting rod 21 to slide and insert, and the surface of the second adjusting rod 22 is provided with a plurality of limiting holes 24, and the plurality of limiting holes 24 are all connected to the slot 23; the locking mechanism 3 can be inserted into or out of the limiting hole 24 to correspondingly lock or unlock the first adjusting rod 21 and the second adjusting rod 22;

[0042] The limiting holes 24 are arranged at equal intervals, and the locking mechanisms 3 are inserted into different limiting holes 24, indicating that the lengths of the beams 2 are different at this time. At the same time, the beams 2 can also be provided with scale lines, and the scale lines can be used to further accurately know the distance between the two inverted U-shaped rods 1.

[0043] Further, such as Figure 4 As shown, the locking mechanism 3 includes a top column 31 and a limiting column 32. The surface of one end of the first adjusting rod 21 extending into the slot 23 is provided with a limiting groove 33 for the top column 31 to slide. The limiting column 32 is installed at the bottom of the limiting groove 33. The end of the top column 31 extending into the limiting groove 33 is provided with a guide groove 34 for the limiting column 32 to slide. A telescopic spring 35 mounted on the limiting column 32 is connected between the top column 31 and the bottom of the limiting groove 33.

[0044] When the operator needs to adjust the position, the push column 31 is pressed by hand, and the push column 31 slides along the limit column 32 under the action of the external force. While pressing the push column 31, it is also necessary to push the inverted U-shaped rod 1 on one side to move. Since the push column 31 slides along the limit column 32 to the limit groove 33 under the external force, the telescopic spring 35 is compressed by the push column 31 and elastically deforms. That is, when the inverted U-shaped rod 1 on one side is pushed, the push column 31 contacts the side wall of the slot 23 in the second adjustment rod 22 until the push column 31 moves to the next limit hole 24. When it moves to the next limit hole 24, the elastically deformed telescopic spring 35 will reset, and the force generated by the telescopic spring 35 drives the push column 31 to slide along the limit column 32 until it is inserted into the limit hole 24.

[0045] When the first adjusting rod 21 is inserted into or pulled out of the second adjusting rod 22, the top of the top column 31 contacts the side wall of the slot 23 for a period of time. The friction between the top column 31 and the slot 23 is the maximum resistance to the sliding between the first adjusting rod 21 and the second adjusting rod. In order to achieve the effect of quickly and conveniently adjusting the length of the beam 2, the friction needs to be reduced as much as possible.

[0046] Specifically, Figure 2-4 As shown, the end of the top column 31 away from the limit column 32 is rotatably connected to the ball 36. Since the friction force generated by rolling friction is smaller than the static friction force, the first adjusting rod 21 and the second adjusting rod 22 can be easily inserted or pulled out. That is, the deeper the first adjusting rod 21 is inserted into the second adjusting rod, the smaller the distance between the two inverted U-shaped rods 1 is, which is suitable for people with thinner bodies. Conversely, the smaller the depth of the first adjusting rod 21 inserted into the second adjusting rod, the larger the distance between the two inverted U-shaped rods 1 is, which is suitable for people with fatter bodies.

[0047] The legs at the openings of the two inverted U-shaped rods 1 can also be configured to be aligned with the crossbeam 2 structure on which the locking mechanism 3 is installed, that is, the length of the legs at the openings of the inverted U-shaped rods 1 can also be adjusted, thereby being able to adjust the height of the entire walker.

[0048] Further, such as Figure 1 As shown, the ends of the two inverted U-shaped rods 1 are provided with control buttons 4 for controlling the alarm. The user can trigger the alarm by pressing any one of the control buttons 4 or pressing both control buttons 4 at the same time, so as to alert the people around.

[0049] Furthermore, Figure 1As shown, pressure sensors 5 are provided at the ends of the two inverted U-shaped rods 1, and the two pressure sensors 5 can be connected to the alarm for communication. The positions of the two pressure sensors 5 are exactly where the user holds the two inverted U-shaped rods 1 with both hands, and when the user holds the two inverted U-shaped rods 1 with both hands or both hands leave the two inverted U-shaped rods 1, no alarm sound will be issued. Only when the patient holds one side of the handrail with one hand and applies a certain pressure ≥ 10kg, the alarm on the walker will issue an alarm sound to remind the user to use it correctly and in accordance with regulations.

[0050] Among them, the connection between the control button 4, the alarm, and the pressure sensor 5 all belong to the system control. In the design, it is only necessary to write the correct control program and accurate wiring to realize the corresponding functions, which will not be elaborated here.

[0051] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
