Description

The crutch of convertible footing

Technical field:

The utility model relates to the elderly's auxiliary daily necessities, and promptly the crutch product technical field is a kind of crutch of the footing of conversion at any time.

Background technology:

As everyone knows, existing walking stick generally is in the upper end of walking stick bar handle to be set, the lower end is provided with the non-slip feet of making of elastomeric material, people are in mountain-climbing, in the skiing process, usually hand-held crutch, to play the supplemental support health, keep one's balance, effects such as human body onward impulse are provided, it is bigger that most non-slip feet is made the area of non-slip feet bottom in order to increase contact area, yet, under some special situations, for example: more sliding, on the harder ice and snow face, the rubber antiskid pin of walking stick is difficult to find fulcrum again, and greatly reducing walking stick can body support, the effect of onward impulse is provided to human body.

Summary of the invention:

The purpose of this utility model provide a kind of can be according to different road surfaces, conversion has the crutch of the footing of difference in functionality easily at any time.

The utility model is achieved in that the crutch of convertible footing, mainly form by handle, crutch bar and non-slip feet, it is characterized in that being provided with the footing converting means between non-slip feet and crutch bar, the footing of the rigid posts in the footing converting means can stretch out or indentation between two parties in the bottom of non-slip feet.

Above-mentioned footing converting means mainly comprises:

Sleeve: its top can be connected with the lower end of crutch bar is embedded, the centre of its middle and lower part is a cavity, the sidewall that free cavity segment is arranged of sleeve is provided with locating hole, locating hole reaches the guide groove that is communicated with last locating hole and following locating hole down, and the operating handle of rigid posts can move in last locating hole, following locating hole and guide groove;

Rigid posts: be arranged in the cavity of sleeve moving up and down and can in last locating hole or following locating hole, locate by the operation of the operating handle outside the sidewall that stretches out sleeve that is connected with rigid posts rigid posts.

Bottom in above-mentioned non-slip feet outwards offers the actiniform bar-shaped trough that communicates with inner chamber by the center, so that the footing of rigid posts backs down the dihedral pawl of bar-shaped trough formation and reaches outside the bottom of non-slip feet.

Above-mentioned non-slip feet is made with elastomeric material, and above-mentioned rigid posts is made with metal material or reinforced plastics material.

The outstanding compared to existing technology advantage of the utility model is:

1, the utility model makes a walking stick have the function of two kinds of footing owing to the footing converting means that has increased walking stick, both can use anti-skidding footing on general road surface, can use sharp, harder footing again on the ice and snow face that picture is slided.

2, non-slip feet of the present utility model is convenient with the conversion of the footing that point is harder, can use non-slip feet as long as the operating handle of rigid posts upwards is drawn to locating hole, the operating handle of rigid posts is pushed to down locating hole downwards can use sharp, harder footing.

3, reasonable in design of the present utility model is made easily, and functional mapping is convenient, is convenient to large scale application.

Fig. 6 is the last locating hole on the sleeve, following locating hole, the view of guide groove when the front.

The specific embodiment:

With specific embodiment the utility model is further described below:

Referring to Fig. 1-6: the crutch of convertible footing, mainly form by handle 10, crutch bar 20 and non-slip feet 30, it is characterized in that between non-slip feet 30 and crutch bar 20, being provided with the footing converting means, the footing 502 of the rigid posts 50 in the footing converting means can stretch out or indentation between two parties in the bottom of non-slip feet 30, when footing 502 stretches out between two parties in the bottom of non-slip feet 30, can use point, harder footing 502 to grasp the road surface, for the sportsman provides anti-skidding support and power; When footing 502 is retracted into non-slip feet 30 inside, can use larger area non-slip feet 30 to grasp the road surface, for the sportsman provides support and power.

Above-mentioned footing converting means mainly comprises:

Sleeve 40: its top 404 can be connected with the lower end of crutch bar 20 is embedded, the centre of its middle and lower part is a cavity 403, the sidewall that cavity 403 parts are arranged of sleeve 40 is provided with locating hole 401, locating hole 402 reaches the guide groove 403 that is communicated with last locating hole 401 and following locating hole 402 down, and the operating handle 50 1 of rigid posts 50 can move in last locating hole 401, following locating hole 402 and guide groove 403;
