Description

[0001] Crutches with auxiliary support [0002]

The present invention relates to a crutch for which an auxiliary support part is provided, and more particularly to a crutch for which an auxiliary handle and an auxiliary supporting part operated by the auxiliary handle are cleanly used indoors, .

Generally, according to the crutches of the Registration Practical Newspaper Registration No. 20-0398697, crutches are devices mainly used by patients with limited legs such as handicapped persons or fractures, so that they can walk in place of the uncomfortable legs while maintaining the balance of the body .

A holding part located at the upper end as a prior art; A support member coupled with the to-be-bonded portion; A handle coupled between the supports; In a conventional crutch provided with a ground portion supported on the ground, a pair of connecting pieces spaced apart from each other between a pair of semicircular frames is integrated, and the plane between the semicircular frames of the supporting frame and one side of the connecting piece Wherein a hole is formed at a predetermined interval in the longitudinal direction of the connecting piece of the support, and a long bolt penetrating the handle is inserted into a predetermined position hole between the pair of connecting pieces to be engaged and fixed by a butterfly nut Crutches.

As another prior art, according to Registered Utility Model Registration No. 20-0408541, a crutch capable of easily adjusting its height has an upper neck formed with a fastening portion to be fitted to an armpit at an upper portion thereof and a handle at an intermediate portion thereof, And a lower end of the upper neck is provided with a fixing lever connected to one end of the connecting cord so as to be movable up and down, A first spring having elasticity is embedded in the moving part, and a plurality of fixing grooves are vertically formed at a predetermined interval on one side of the lower neck, and the fixing groove is formed on the other side And a fastener connected to the end is fitted in a state of being closely contacted by a second spring having elasticity. .

But crutches users are hard to walk without crutches. For this reason, it is necessary to use crutches indoors. However, there is a disadvantage in that the bottom of the crutch used in the outdoor is used indoors, so that the room is contaminated and it is inconvenient to adjust the length of crutches.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above problems, and it is an object of the present invention to provide a crutch which is provided with an auxiliary handle and an auxiliary supporting portion, .

The present invention relates to a carcass with an auxiliary supporting portion and includes an upper frame 100 formed of left and right frames 110 and 120 and provided with a handle 130 between the left and right frames 110 and 120, And a supporting part 300 installed on a lower surface of the lower frame 200. The crutch 100 includes a lower frame 200 and a lower frame 200. The lower frame 200 has a lower frame 200, An auxiliary handle 140 is provided on the lower frame 200 and an auxiliary support 150 operated by the auxiliary handle 140 is further provided on the lower frame 200.

Therefore, the present invention has a remarkable effect that the auxiliary handle and the auxiliary supporting portion are provided and the auxiliary supporting portion is used in the room to maintain the cleanliness and adjust the length.

FIG. 1 is a perspective view of a crutch with an auxiliary supporting part according to the present invention (a state in which auxiliary supporting parts are folded, outdoor).
FIG. 2 is a perspective view of a crutch with an auxiliary supporting part according to the present invention (a state in which auxiliary supporting parts are deployed, indoors).

The lower frame 200 is connected to a fixing part 160 and a supporting part 300 is installed on the fixing part 160. The auxiliary supporting part 150 is hinged to the fixing part 160, .

A spring 141 is provided on the auxiliary handle 140 and the auxiliary handle 140 and the auxiliary support 150 on the lower side are connected to each other by a connecting rod 170. When the user touches the auxiliary handle 140 The upper end of the auxiliary supporting part 150 rotates upward about the hinge point by the connecting rod 170 and the lower end rotates downward to reach the floor.

The left and right frames 110 and 120 of the upper frame 100 are formed with upper holes 111 and 121 and lower holes 112 and 122 through which the opposite ends of the auxiliary handle 140 are inserted, Are coupled to the upper and lower holes (111, 121, 112, 122).

The present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of a crutch (a state in which the auxiliary support is folded, outdoor) provided with the auxiliary support portion of the present invention, and Fig. 2 is a perspective view of the crutch where the auxiliary support portion is provided.

The upper frame 100 includes left and right frames 110 and 120 and a handle 130 is installed between the left and right frames 110 and 120. The left and right frames 110 and 120 of the upper frame 100, And a supporting part 300 provided on a lower surface of the lower frame 200.

An auxiliary handle 140 is provided below the handle 130 and an auxiliary support 150 is further provided on the lower frame 200 by the auxiliary handle 140.

A fixing part 160 is connected to a lower surface of the lower frame 200 and a supporting part 300 is installed on the fixing part 160. The auxiliary supporting part 150 is hinged to the fixing part 160.

A spring 141 is installed on the upper part of the auxiliary handle 140 and the auxiliary handle 140 and the lower auxiliary support 150 are connected to each other by a connecting rod 170. When the user hands the auxiliary handle 140, The upper end of the auxiliary supporting part 150 is rotated upwards about the hinge point by the connecting rod 170 and the lower end of the auxiliary supporting part 150 is rotated downward to reach the bottom.

Therefore, in the room, the auxiliary support portion is brought into contact with the floor, so that cleanliness can be maintained. Normally, it is used outdoors while the supporting part touches the ground. Therefore, the length of crutches can be selectively adjusted.

The left and right frames 110 and 120 of the upper frame 100 are formed with upper holes 111 and 121 and lower holes 112 and 122 through which the opposite ends of the auxiliary handle 140 are inserted, 121, 112, and 122 when the upper and lower holes are located at upper and lower portions. The auxiliary handle is pulled upward to allow both ends of the auxiliary handle to be inserted into the upper hole. When the both ends of the auxiliary handle are released from the upper hole, the auxiliary handle is lowered Both ends of the auxiliary handle are inserted into the lower hole. The auxiliary handle is made of an elastic metal material.

Accordingly, the present invention is structured such that the crutch bottom portion used outdoors is indoors, and the clean portion touches the ground.

When a crutcher climbs uphill, the next leap point is relatively higher than the previous leap point, so walking uphill or downhill is easier and safer to walk when the crutch length is shorter than when walking on a flat land.

Whenever sloping terrain such as stairs, uphill slopes, and downhill slopes appear, it is inconvenient to change to the existing length changing method.

On the other hand, it is easy to adjust the length by pulling the handle.
