Description

Technical Field

[0001] The utility model belongs to the technical field of walkers, and in particular relates to a detachable walker. Background Art

[0002] A walker, also called a lower limb orthosis, is a walking support tool for elderly people with limited mobility, some traumatic injuries, hemiplegic patients and disabled people to help them walk or exercise their limbs. People can walk slowly and easily with the help of it. However, most existing walkers are integrated, with multiple steel pipes welded together, which makes the walker impossible to disassemble. During transportation or storage, the entire walker is large in size and occupies more space, which is inconvenient to transport and store. In addition, the existing walker is fixed by welding, and the shape of the entire walker is fixed. When it is not needed for rest, it cannot be folded, resulting in it occupying more space and inconvenient to use. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the utility model is to provide a detachable walker to solve the technical problem that the existing walkers cannot be disassembled, resulting in more space being occupied during transportation or storage, and being inconvenient to transport and store.

[0008] The present application provides a connecting structure on each branch pipe, so that the multiple branch pipes connected together can be disassembled one by one when packaging or storing, thereby disassembling the entire walker as a whole, reducing the volume of the walker and facilitating packaging or storage. In addition, when the two branch pipes connected to each other by the two support frames are detachably connected, the two branch pipes connected to the two support frames can be completely disassembled to completely disassemble the entire walker. When the two branch pipes connected to each other by the two support frames are rotatably connected, the remaining two connected branch pipes can be folded in half after disassembling the other disassembled branch pipes to reduce the space they occupy. The walker of the present application is assembled in a detachable manner as a whole. Compared with the welding method that requires precise docking, the assembly of the present application is more convenient and quick.

[0009] In some embodiments, the connection structure includes: an elastically retractable locking column arranged on the side of one branch pipe end and a locking groove for the locking column to be locked into, which is provided on the side of another branch pipe end adjacent to the branch pipe.

[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0036] The utility model provides a detachable walking aid, comprising: two support frames 1 that are symmetrical and interconnected with each other, each support frame 1 comprising a plurality of branch pipes, at least one end of each branch pipe being provided with a connecting structure, the plurality of branch pipes of each support frame 1 being detachably connected via the connecting structure to form a frame structure, and the two branch pipes of the two support frames 1 butted against each other are detachably connected and / or rotatably connected.

[0037] There are three different connection situations for the two branch pipes of the two supporting frames 1 that are connected to each other:

[0038] See also Figure 1 and Figure 8 In one embodiment, the two branch pipes of the two supporting frames 1 connected to each other are detachably connected. When the entire walker is disassembled, in addition to disassembling all the branch pipes of the supporting frames 1 individually, the two branch pipes of the two supporting frames 1 connected to each other can also be disassembled, thereby completely disassembling the entire walker.

[0039] See also Figure 2 and Figure 3 In the second embodiment, the two branch pipes of the two supporting frames 1 that are butt-jointed are non-detachably rotatably connected, for example, the rotating structure is welded to the two butt-jointed branch pipes. When the entire walker is disassembled, all the detachable branch pipes of the two supporting frames 1 are disassembled, and the remaining two butt-jointed branch pipes can be folded in half, thereby reducing the entire storage space.

[0040] In the third embodiment, the two branch pipes of the two supporting frames 1 that are connected to each other are detachably rotatably connected. For example, the rotating structure is fixed to the two connected branch pipes by screws. When the entire walker is disassembled, all the detachable branch pipes of the two supporting frames 1 are disassembled. The two connected branch pipes can be disassembled, or the two branch pipes can be directly folded in half without disassembling.

[0041] Specifically, the branch pipes of the present application may be round pipes, square pipes or special-shaped pipes, and the present application does not limit the shapes of the branch pipes.

[0042] Specifically, there are many ways of detachable connection, such as:

[0043] The first embodiment: a detachable connection is achieved by engaging a locking column 108 and a locking groove 107 with each other. For example, an elastically retractable locking column 108 is provided on the side of the end of a branch pipe, and a locking groove 107 is provided on the side of the end of an adjacent branch pipe. The two adjacent branch pipes are detachably connected by being inserted into the locking groove 107 through the locking column 108.

[0044] Second implementation mode: a detachable connection is achieved by using a locking hole and a screw locking piece. For example, locking holes are provided on the sides of the ends of two adjacent branch pipes. When connecting, the two branch pipes are inserted so that the two locking holes are aligned. Then, the screw locking piece is inserted into the two locking holes to lock the two branch pipes.

[0045] Since there are many ways to disassemble, it is impossible to list all the ways here. Any way to detachably connect two branch pipes should be included in the scope of this application.

[0046] Specifically, since the number of branch pipes can be various and the shape of each branch pipe can also be various, this application specifically introduces two embodiments:

[0047] See also Figure 8 , Third embodiment: The names of the multiple branch pipes in each support frame 1 are: two-legged pipes 101 symmetrically arranged at the bottom, middle pipes 102 respectively arranged above the two-legged pipes 101 and detachably connected to the corresponding leg pipes 101, and bent pipes with a curved structure arranged above the middle pipe 102 and detachably connected to the two middle pipes 102 at both ends, wherein a connecting pipe 105 is extended laterally on the middle pipe 102, and the connecting pipes 105 of the two support frames 1 are detachably connected and / or rotatably connected. Specifically, the number of middle pipes 102 on both sides can be one with a longer length, or multiple short ones connected to each other;

[0048] See also Fig. 9, Fourth embodiment: The multiple branch pipes of each support frame 1 are: two leg pipes 101 symmetrically arranged at the bottom, a middle pipe 102 arranged above one leg pipe 101 and detachably connected to the leg pipe 101, and a curved pipe 103 in a 7-shaped structure arranged above the middle pipe 102 and the other leg pipe 101, wherein the two ends of the curved pipe 103 are detachably connected to the middle pipe 102 and the other leg pipe 101, respectively, wherein the middle pipe 102 extends laterally to form a connecting pipe 105, and the connecting pipes 105 of the two support frames 1 are detachably connected and / or rotatably connected, and this method can save one leg pipe 101.

[0049] See also Figure 4 and Figure 5 For the implementation method of the rotatable connection of the two connecting tubes 105, the present application sets the middle tube 102 on one side of the support frame 1 to be rotatable with the curved tube 103. Specifically, the card slot 107 connecting the middle tube 102 and the curved tube 103 is optimized into an arc structure, and the card column 108 of the middle tube 102 is inserted into the card slot 107 of the curved tube 103. For the assembled walker, the two support frames 1 can be pushed toward the center when not in use. At this time, the two connecting tubes 105 are under the action of external force. The middle tube 102 and the connecting tube 105 are connected, and the leg tube 101 is connected to the middle tube 102. When the connecting tube 105 rotates, the middle tube 102 and the leg tube 101 rotate at the same time, and the engaging column 108 of the middle tube 102 rotates from one side to the other side along the arc-shaped groove 107, and finally the two support frames 1 are brought close to each other and folded in half. When the walker needs to be unfolded, the two support frames 1 are pulled in the opposite direction to rotate the two connecting tubes 105 to the position where the ends are butted against each other.

[0050] See also Figure 7Preferably, the present application further provides a limiting structure 3 on the curved tube 103 to limit the rotation angle of the middle tube 102. Specifically, the limiting structure 3 includes: a fixing seat 301 and a limiting member 302. The fixing seat 301 is arranged around one end of the curved tube 103 close to the middle tube 102. The limiting member 302 is hinged on the fixing seat 301. The limiting member 302 is provided with a protrusion 3021. A through hole 1031 is provided on the curved tube 103. A limiting hole 1021 is provided on the middle tube 102. When the limiting hole 1021 of the middle tube 102 rotates to a position corresponding to the through hole 1031, the limiting member 302 is driven to rotate to insert the protrusion 3021 into the through hole 1031 and the limiting hole 1021 at the same time to limit the middle tube 102 to continue rotating. Furthermore, a torsion spring is provided at the hinge between the limit member 302 and the fixing seat 301, the upper end of the torsion spring is connected to the limit member 302, and the lower end is connected to the fixing seat 301. When the walker is in the folded state, the protrusion 3021 of the limit member 302 passes through the through hole 1031 and keeps in contact with the outer wall of the middle tube 102. At this time, the torsion spring remains in a deformed state. When the walker is unfolded, the middle tube 102 rotates following the connecting tube 105. When the limiting hole 1021 of the middle tube 102 rotates to a position corresponding to the limit member 302, the torsion spring resets and drives the protrusion 3021 to be inserted into the limiting hole 1021 to limit the rotation angle of the middle tube 102. When the walker needs to be folded again, it is only necessary to press the hinged end of the limit member 302 again to make the protrusion 3021 disengage from the limiting hole 1021.

[0051] Specifically, in view of the rotational connection method of the two connecting tubes 105, a rotation locking structure 2 can be set at the ends of the two connecting tubes 105. The rotation locking structure 2 can be a self-locking rotating shaft. The two connecting plates of the self-locking rotating shaft are respectively connected to the two connecting tubes 105. When the two connecting tubes 105 are rotated to the position where the ends are butted against each other, the self-locking rotating shaft can lock the positions of the two connecting tubes 105. Specifically, since the self-locking rotating shaft is a conventional component on the market, its internal structure will not be described in detail here.

[0052] Preferably, the present application further adds a reinforcing tube 106, and tube sleeves 1061 are provided at both ends of the reinforcing tube 106. The tube sleeves 1061 are respectively sleeved on two middle tubes 102 (third embodiment) or on a middle tube 102 and a bent tube 103 (fourth embodiment) to strengthen the middle strength of the support frame 1. The reinforcing tube 106 is connected to the middle tube 102 through the tube sleeve 1061. In addition to realizing a detachable connection, it can also avoid hindering the rotation of the middle tube 102.

[0053] Preferably, the present application further adds an extension tube 104, which is arranged below the leg tube 101. The extension tube 104 is provided with a plurality of slots 107 arranged in sequence along its length direction, for the locking column 108 of the leg tube 101 to be inserted into the predetermined slot 107 to extend or shorten the length of the leg tube 101.

[0054] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
