Description

Handheld crutches reset structure

This creation is about a "hand-held cane reset structure", especially a hand-held cane structure that combines universal yaw, rebound buffer and active reset.

According to the traditional cane, the impact formed by the traditional cane without contact with the ground will directly affect the body. The creator has developed a crutches grounding support structure with a cushioning effect. The eighth figure, or the one disclosed in the national patent certificate No. M458223, is mainly connected with a grounding member at the bottom end of a crutches (70), the grounding member comprising: a base (75) having a spherical guiding surface ( 751), the center of the spherical guide (751) is provided with an enlarged middle hole (752), and the bottom end of the base body is combined with a buffer block (79), and an inner guide block (76) is a top surface. An arc-shaped block having a stepped perforation (761) in the center, the sleeve being placed in the base (75) to abut against the inner surface of the spherical guide surface (751), and an outer sleeve (71) a hollow sleeve that can be inserted into the lower end of the crutches (70), the bottom end of which is provided with a perforation (711) for the support rod (72), and an arc-shaped guide groove corresponding to the spherical guide surface (751) is expanded ( 712), the inner surface of the arcuate guide groove (712) is coupled with an abutment ring (74), and the abutment ring (74) abuts against the spherical guide surface (751), and a support rod (72) Through the elastic element (7 3), the outer sleeve (71), the base (75), the inner guide block (76), and the inside of the base (75) is combined with a fixing member (78), so that each The components can be pivoted, the support rod (72) can be a screw, and the fixing member (78) can be a nut, and the perforation (761) is fixed in the fixing member (78) and the inner guiding block (76). The spring (77) of the auxiliary fixed support rod (72) is sleeved between the large diameter holes, and an elastic member (73) is sleeved on the outer side of the support rod (72) in the outer sleeve (71), and one end is abutted against The bottom end of the outer sleeve (71) and the other end abut against the enlarged screw head of the support rod (72), so that the crutches (70) can form a rebound buffer ground support structure in the outer sleeve (71).

In use, the outer arc-shaped guide groove (712) and the inner guide block (76) of the outer sleeve (71) abut against the inner and outer surfaces of the spherical guide surface (751) of the base (75), respectively. Then, through a support rod (72), the components are pivoted and combined, so that the crutches (70) can form a universal random yaw effect. When the crutches (70) are walking, the buffer block (79) can be used with different terrain angles. Forming a stable support for full contact, effectively preventing the occurrence of slippage, and achieving the effect of improving safety in use.

However, after the developer created the creation case, he was not complacent, and continued to think about R&D in the spirit of excellence, striving to make this structural feature more vivid and easy to use. During the process, it was found that the above-mentioned pre-case structure still has the following problems in practical application: after the crutches (70) universal yaw, it does not have an active reset effect, so that the user needs to apply an external force to the crutches ( 70) Correction (such as the solid arrow in the ninth figure), in order to continue to carry forward with the crutches (70), the use is more laborious and troublesome, the system will greatly reduce the consumer's willingness to use.

Therefore, the person who wants to reveal this creation is a new type of structural designer who has made improvements and breakthroughs in the shortcomings of the creator's related previous case structure.

The main problem is to improve the breakthrough of the problem that the creator has previously developed that the cane can not be actively reset.

The present invention provides a hand-held crutches resetting structure, comprising: a crutch, a base, an outer sleeve, a support rod set, an elastic return member and a foot seat, and the support rod set is composed of a support rod and an elastic The component, an inner guiding block, a spring and a fixing component are combined, wherein the base is a seat body having a spherical guiding surface, and an enlarged middle hole is arranged in the center of the spherical guiding surface, and the bottom of the base is to be After the inner guiding block, the spring, the fixing member, the elastic returning member and the like are placed inside, the inner guiding block is combined with the above-mentioned foot seat, and the inner guiding block is a top surface embedded natural component And an arc-shaped block body having a stepped through hole in the center of the inner guide block, the inner guide block being placed inside the base, and the ball is passed through the abutting member to abut on the spherical guide surface inside the base The outer sleeve is a hollow sleeve that can be inserted into the lower end of the cane, the bottom end is provided with a perforation for the support rod, and the outer expansion has an arc-shaped guide groove corresponding to the spherical guide surface, the arc The inner surface of the guide groove is coupled with an abutment ring, and the abutment ring abuts against the spherical guide surface The end of the support rod is continuous through the elastic element, the through hole of the outer sleeve, the middle hole of the base, the stepped perforation of the inner guide block, and then the inside of the base and the fixed The combination of the pieces, by the limitation of the combination of the support rod and the fixing member, enables the outer sleeve and the inner guide block to obtain a pivot group on the base, the above The spring is sleeved on the support rod and is supported between the fixing member and the large-diameter hole of the stepped perforation, and the elastic support of the spring can generate an auxiliary positioning effect on the support rod. The elastic member is sleeved on the outer side of the support rod in the outer sleeve, one end abuts against the bottom end of the outer sleeve, and the other end abuts on the support rod, so that the crutches can be The effect of the rebound buffer is generated in the outer sleeve, the elastic return member has a bottom portion and a conical spiral body which is tapered upward from the bottom portion, and a set of mouth is formed above the spiral body, when the elastic reset member Putting into the interior of the base, and when the base is combined with the foot, the end of the support rod can be provided with the sleeve, so that the elastic return member can be smoothly clamped in the Between the foot and the inner guiding block, the inner side of the inner guiding block produces an elastic topping effect, thereby obtaining a hand-held crutches resetting structure.

The present invention provides a hand-held crutches resetting structure, which utilizes the installation of the elastic returning member, and can utilize the elastic force of the elastic returning member to actively reset the crutches into a vertical state after the angle of the walking process is changed, so that the user does not need to additionally apply An external force will correct the crutches, and the use will be more labor-saving and convenient, so as to greatly increase the consumer's willingness to use.
