Description

Technical Field

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

[0002] Existing walkers generally install the H-frame between two side frames. The side frames are generally an inverted U-shaped structure. When the user uses the walker and leans forward, the H-frame provides support and maintains the stability of the side frames. However, existing walkers directly fix the H-frame on the side frames, which requires the side frames to be machined with corresponding installation stations at the installation position of the H-frame to adapt to a certain model of H-frame, otherwise a new H-frame needs to be redesigned. To this end, the side frames need to be provided with extension sections corresponding to the H-frame on the H-frame, and the extension sections will cause the extension direction, angle, size and other parameters of the H-frame to be fixed, which in turn causes the shape of the H-frame to be fixed. The structure of the H-frame and the side frames will directly affect the overall appearance of the walker, thereby making the overall shape of the walker single, that is, it is impossible to effectively achieve both fixed stability and aesthetics.

[0033] like Figure 1-4 , a walking aid, comprising: a side frame 1, a fixing tube 2, an H frame 3 and a connecting frame 4;

[0034] The side frames 1 are arranged in pairs on the left and right sides; one end of the fixed pipe 2 is fixed to the side frame 1; the H frame 3 is provided with a frame connecting rod 31 and a pipe-containing rod 32; the two ends of the frame connecting rod 31 are respectively connected to the pipe-containing rod 32; the pipe-containing rod 32 is fixed to the fixed pipe 2; one end of the connecting frame 4 is connected to the side frame 1 on one side, and the other end of the connecting frame 4 is connected to the side frame 1 on the other side.

[0035] This solution provides a walker, which fixes a fixing tube 2 to a side frame 1, then uses an H-frame 3 to fix the fixing tubes 2 of the two side frames 1 into one body, and uses a connecting frame 4 to fix the two side frames 1, forming a stable structure. Moreover, since the H-frame 3 is fixed to the fixing tube 2 of the side frame 1, the shapes of the side frame 1 and the fixing tube 2 are more diverse, and the side frame 1 does not need to be provided with an additional structure to provide a support point for the H-frame 3, thereby avoiding the problem that the H-frame 3 is limited in the appearance and shape design of the walker due to the installation of the fixing tube.

[0036] Specifically, the side frames 1 are generally located on both sides of the walker; the side frames 1 can be provided with fixed tubes 2, and the installation method of the fixed tubes 2 on the side frames 1 can be one-piece molding, welding, clamping, etc.; the side frames 1 have been fixed with fixed tubes 2, and the fixed tubes 2 replace the side frames 1 to install the H-frame 3; the H-frame 3 is provided with a frame connecting rod 31 and a tube-containing rod 32, and the tube-containing rod 32 is respectively installed on the fixed tubes 2 of the side frames 1 on both sides, and the tube-containing rod 32 is fixed to the fixed tube 2, for example, the tube-containing rod 32 is coaxially fixed to the fixed tube 2; the frame connecting rod 31 connects the two tube-containing rods 32, so that the fixed tubes 2 of the two side frames 1 are fixed together; the connecting frame 4 then connects the side frames 1 on both sides to open the side frames 1; in this way, the H-frame 3 and the connecting frame 4 are formed at the side frame 1 The triangular support structure props up the side frame 1, providing primary stability for the side frame 1. In this solution, since the fixed tube 2 replaces the side frame 1 to mount the H-frame 3, the H-frame 3 is not mounted directly on the side frame 1. The side frame 1 does not need a specific location for mounting the H-frame 3's tube-receiving rod 32. When the H-frame 3 is required, simply attach the fixed tube 2 compatible with the H-frame 3 to the side frame 1. The curvature, extension trajectory, shape, and size of the fixed tube 2 can be customized as needed. Furthermore, the side frame 1's non-fixed tube 2 portion can be designed in any shape, without requiring consideration for the ease of securing the H-frame 3. This eliminates the need to reserve additional space for mounting the H-frame 3. This allows the walker to have a more diverse design in the H-frame 3 portion. As the walker's primary framework, the diverse shapes of the side frame 1 allow for a more diverse design of the main frame. This solution avoids the problem of the H-frame 3 being restricted in its design.

[0037] Optimally, it further includes: a sealing member 5;

[0038] The sealing member 5 is provided with a pipe opening groove 51 and a clamping opening 52 ; the pipe opening groove 51 is located at the other end of the fixed pipe 2 ; and the clamping opening 52 is fixed to the side frame 1 .

[0039] One end of the fixed tube 2 is fixedly mounted on the side frame 1, and the other end is connected to the sealing member 5; specifically, the tube opening groove 51 of the sealing member 5 can limit one end of the fixed tube 2, and the clamping opening 52 of the sealing member 5 can be clamped on the side frame 1, thereby improving the bonding between the fixed tube 2 and the side frame 1, and concentrating the force on the fixed tube 2 on the entire fixed tube 2 rather than between the fixed tube 2 and the side frame 1, thereby improving the stability of the H frame 3.

[0040] Optimally, it further includes: a locking screw 6;

[0041] A locking opening 53 is provided in the clamping opening 52 . The screw rod of the locking screw 6 passes through the side frame 1 and is threadedly engaged with the locking opening 53 , so that the clamping opening 52 is restricted to the side frame 1 .

[0042] When the clamp 52 clamps the side frame 1, the fixing force of the clamp 52 on the side frame 1 can be improved by the locking screw 6. The screw thread of the locking screw 6 is matched with the locking hole 53, so that the screw head of the locking screw 6 is pressed against the side frame 1, thereby fixing the clamp 52 to the side frame 1, thereby improving the fixing stability of the fixed pipe 2 and the H frame 3 on the side frame 1.

[0043] Optimally, it further includes: a locking screw 6;

[0044] The pipe mouth groove 51 is arranged on the inner circle of the fixed tube 2, and a locking opening 53 is provided on the outer side of the pipe mouth groove 51; the screw of the locking screw 6 passes through the fixed tube 2 and is threadedly engaged with the locking opening 53, so that the pipe mouth groove 51 is limited to the fixed tube 2.

[0045] The rod of locking screw 6 passes through fixed tube 2 and then threads into locking notch 53 of pipe opening slot 51, thereby confining pipe opening slot 51 to the inner circle of fixed tube 2. This prevents shaking between the sealing member 5 and fixed tube 2 and limits the relative angle between them, thereby improving the stability between fixed tube 2 and side frame 1. When both pipe opening slot 51 and clamping opening 52 of sealing member 5 are restrained by locking screw 6, fixed tube 2 and side frame 1 are tightly coupled and optimally stabilized.

[0046] Optimally, the outer side surface of the fixed tube 2 is provided with a resettable elastic limiter 21; the tube-containing rod 32 is provided with multiple adjustment grooves 321 along the length direction of the fixed tube 2; the elastic limiter 21 is snapped into one of the adjustment grooves 321, so that the tube-containing rod 32 is limited to a certain position of the fixed tube 2.

[0047] The elastic limiting member 21 is elastic, for example Figure 3 The spring piece is used to control its resettable movement to extend or retract on the outer side of the fixed tube 2; the elastic limiting member 21 is movably adjustable on the outer side of the fixed tube 2, and can extend from the outer side of the fixed tube 2 or detach from the outer side of the fixed tube 2 as needed; when it is necessary to adjust the position of the tube-containing rod 32 in the fixed tube 2, the position of the elastic limiting member 21 can be adjusted to make the elastic limiting member 21 detach from the outer side of the fixed tube 2, so that the tube-containing rod 32 can move normally in the fixed tube 2 until the adjustment groove 321 of the tube-containing rod 32 is placed in the storage position of the elastic limiting member 21, and the elastic limiting member 21 is reset and clamped in the adjustment groove 321. The mutual limitation between the adjustment groove 321 and the elastic limiting member 21 can fix the tube-containing rod 32 in the position of the fixed tube 2, thereby realizing the function of flexibly adjusting the position of the H-frame 3 on the fixed tube 2.

[0048] Optimally, the side frame 1 includes: a U-shaped frame 11 and a support rod 12;

[0049] The U-shaped frame 11 is provided with a U-shaped opening 13 , and the left and right ends of the support rod 12 are respectively connected to the left and right sides of the U-shaped opening 13 .

[0050] Generally, the side frame 1 in the walker is provided with a U-shaped frame 11, and the bottom of the U-shaped frame 11 is two supporting legs, that is, the side frames 1 on the left and right sides form four supporting legs; one end of the support rod 12 is installed on the left side of the U-shaped opening 13, and the other end of the support rod 12 is installed on the right side of the U-shaped opening 13. In this way, the two supporting legs are fixed to open the U-shaped opening 13, thereby improving the fixing stability of the single side frame 1.

[0051] The support rod 12 can be installed in the U-shaped opening 13 in a known manner, such as by screwing.

[0052] Optimally, the middle portion of the support rod 12 gradually extends obliquely upward toward both ends, and both ends of the support rod 12 extend to below the position of the fixing tube 2 on the side frame 1 ; the lower end of the fixing tube 2 is mounted on the side frame 1 .

[0053] The fixing tube 2 extends vertically, and its lower end is mounted on the side frame 1. Therefore, when force is applied to the H-frame 3, the H-frame 3 applies pressure to the fixing tubes 2 of the side frames 1 on both sides, so that the force on the side frames 1 at the position of the fixing tubes 2 is maximized. To this end, the support rod 12 is extended from the middle to both ends in this solution, so that the support rod 12 forms a triangular stable structure in the U-shaped opening 13, thereby supporting the side frames 1 below the fixing tubes 2 from bottom to top, thereby improving the structural stability of the side frames 1 at the fixing tubes 2, thereby improving the stability of the walker.

[0054] Optimally, the connecting frame 4 is connected to the top of the side frame 1 , and the connecting frame 4 , the fixing pipe 2 and the support rod 12 are fixed to the U-shaped frame 11 in sequence from top to bottom.

[0055] The connecting frame 4 is connected to the top of the side frame 1 to stabilize the top of the walker; the fixing tube 2 is set in the middle of the side frame 1 to stabilize the middle of the walker; the support rod 12 can lift the side frame 1 from the bottom up under the fixing tube 2, which can reduce the pressure on the fixing tube 2; with such distribution, the walker of this solution has good stability, and the side frame 1 and the fixing tube 2 have various shapes.

[0056] The connecting frame 4 can be connected to the side frame 1 by known methods, such as screw fixation, clamp fixation, snap fixation, etc.

[0057] Optimally, the fixing pipe 2 is fixed to the side frame 1 by welding.

[0058] In this solution, the fixing tube 2 is preferably welded to the side frame 1. On the one hand, the fixing tube 2 and the side frame 1 are highly integrated and not easily deformed. On the other hand, both the fixing tube 2 and the side frame 1 can be processed into the required shape before installation, making the processing of the walker more flexible.

[0059] Optimally, the fixing pipe 2 is detachably fixed to the side frame 1 .

[0060] The fixing tube 2 can also be detachably mounted on the side frame 1, for example, by screw fixation, clamp fixation, snap fixation, etc. When the fixing tube 2 is detachable, when the structure of the walker needs to be switched, the fixing tube 2 can be immediately removed from the side frame 1 and then replaced with a fixing tube 2 or side frame 1 of other shapes, thereby obtaining a walker of different shapes, which has high flexibility of use.

[0061] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
