Abstract

Disclosed is a runner crutch. The front end of the crutch is equipped with a runner. When the runner is rotated on the ground, the body can continually walk by the crutch. A holding pole is mounted reversely in a marching direction because of unstable walking by using only one crutch, and the front end of the holding pole is also equipped with a runner. The walking does not rely on the crutch touching the ground, but relies on the rotating of the runner. When in confusion places or walking up and down the stairs, the crutch is slightly inclined and then can be automatically folded. Furthermore, the crutch is also equipped with a brake and can be used in the road, trolley and bus.

Description

Rotary wheel type walkstick

The present invention is on the basis of an existing crutch, adds a pole and loads onto the rotary wheel type walkstick of wheel at its front end, closes and can automatically fold at crowded field boundary, and can also transport a spot of article in body support.

Now, the notion of crutch is that the front end with a rod lands, and that is to say, grasp an end top of a rod (containing pipe), other end bottom lands, and every one step of row crutch all wants built on stilts to cooperate walking forwards to move with body support, is the instrument of auxiliary walking.

Auxiliary walking is called the instrument of walker in addition except that crutch, walker is a body support incessantly, in its underpart four wheels is housed, and the people stands in the centre of four wheels, hands and arm ride over the upper ledge that becomes one with wheel and come body support, and rotating wheel moves.

Also just like clear and 61 (1986)-34342 prior aries of being announced of special permission communique, with three wheels it is not fallen without four wheels, in the middle of the people stands in, only taken framework a side, handle and arm ride over upper ledge and come body support, and rotating wheel moves.These all are in hospital and just operable instrument are arranged in the training institute of facility etc. distinguishingly, and can not use on road.Therefore, wish to have a kind of instrument that can use in road or crowded places, for example, at city's field boundary, in electric car and the bus.

Crutch all can use at road in crowded places.An existing crutch is the balance that all will obtain health every length by length one step of row, the crutch built on stilts, cooperate the walking position that lands forwards to move, therefore move owing to leaning on crutch, and during the crutch built on stilts, must average out with own self foot, so to patient, old man and people with disability exist uneasy sense, some people must bend waist very seriously or take the unusual bodily form.

Therefore, deal with problems just otherwise mention crutch, can move under the state of body support always and close at crowded field boundary and fold up use, if some place just can open and use, this all is automatically to change under the state that crutch lands.

Break away from every one step of row of crutch and all want built on stilts, and then the traditional view that lands, front end at crutch is loaded onto roller, constantly lean on the crutch that rotates and walk, it is unsettled only loading onto wheel turns at the front end of a crutch, and a pole is considered to add in the place, from crutch, become inclination opening to install earthward, like this, crutch, pole and ground triangularity are for well.Certainly also load onto wheel at the front end of pole.

This structure is as clear similar with 61-34342 with the special permission communique, and actually this is not so.

The walker that comes from the development of the walker of four fulcrums stable the standing that do not fall down to the ground itself, in order to support human body, the axletree sidewards in the place ahead of people, and wheel is housed at its front end.At road or this axletree sidewards of crowded places obstruction is arranged, no matter how to say that this is at the employed walker of particular field.

And the present invention is considered to from the crutch development come, and is the side at human body, though two front-wheels and two trailing wheels are arranged, (this is to want to make it when hands leaves, can not topple at once, slightly some instability also can), but banner is very narrow, and crutch lands and opens on direct of travel.Therefore yet inconvenience when crowded place and stair activity under open mode is tilted it a little or is just upwards carried and can automatically fold, and can land and turns.No matter how to say that this is the crutch that works in the use of people's body side surface.

And then, for preventing brake also to be installed in the danger on ground such as ramp.This crutch is named as " rotary wheel type walkstick ".

The side and the wide cut that only are used in human body as crutch are set as out of the way degree, the crutch that can lean on this structure is incessantly walked, in crowded place slightly backward or turn forward with rotary wheel type walkstick, front-wheel or trailing wheel one built on stilts will automatically fold and diminish, the rotation that can in the same old way land can be used as crutch and uses.

Use brake in the hazardous area, both considered safety, simple again, light on the whole.Find that through experiment bow-backed old man uses this rotary wheel type walkstick, has directly walked to the waist back stretching.

Adopt the four wheels hands to leave Shi Buhui in addition and topple at once, hanging hook is installed, increased the convenience of user on the top of rotary wheel type walkstick.

The 1st figure is the side view of this rotary wheel type walkstick, and the 2nd figure is a front view, and the 3rd figure is the side view of folded state.

Crutch 1 is to make with hollow pipe, end bending 90 degree-120 degree are as handle up, supporting running roller 3 in the both sides, bottom respectively with bearing pin 14, at intermediary two positions bracket 5 is arranged, bracket 6 as outer shroud with crutch 1 serve as the axle make crutch 1 freely to rotate suit, bracket 5 is provided with protuberance, supporting the pole 2 that hollow pipe is done with bearing pin 8 at this protuberance, also be provided with protuberance on the bracket 6, supporting connecting rod 12 with bearing pin 9 at this protuberance, both sides, bottom pole 2 are being supported running roller 4 respectively with bearing pin 15, on pole, fixing bracket 7, also be provided with protuberance on the bracket 7, supporting an end of connecting rod 13 at this protuberance with bearing pin 11, connect connecting rod 12 and connecting rod 13 by bearing pin 10, the stretching degree of pole is the state that connecting rod 12 and connecting rod 13 are stretched out fully to the maximum, connect bracket 5, bracket 6, the bearing pin axle center of bracket 7 forms the triangle with base, (returning spring 18 is provided with the position and can changes as described later in bearing pin 9 grades, therefore claim etc.) around twine returning spring 18, when the running roller built on stilts (when handle is upwards mentioned) automatically make progress at returning spring 18 effect lower bearing pins 10, become rugosity shown in Figure 3.The position is set also can on bearing pin 10, bearing pin 11, can also be connected between bearing pin 8 and the bearing pin 10 of this returning spring 18 with extension spring.

And then, dangerous in the rolling meeting of local running rollers such as ramp, so brake unit has been installed.Brake bar 19 has been installed near handle 17, nearly running roller one side pole 2 is being propped up rocking arm 23 with 24 of bearing pins, has the external diameter that outwardly directed brake(-holder) block 25 can be pressed both sides running roller 4 simultaneously in the both sides of rocking arm 23 1 ends, the other end is used from the outside line 20 middle steel wires that pass through and is connected with brake bar 19, catches the handle 17 and the brake bar 19 of top can brake once holding with a firm grip.This brake unit also can be positioned on crutch 1 one sides.

In addition, running roller also can be the wheels in front and back, also can be four wheels, even hands leaves also can not fall down at once, still, the interval of two wheels measures from the outside and is less than 14cm not hinder walking.

And, the hanging hook of a wide U word shape is housed on the top of bracket 5, makes this rotary wheel type walkstick can transport some article, the adjustment screw 21 of steel wire is equipped with in the end of the outside line 20 before brake bar 19, the turn screw can be adjusted the flexible of steel wire in the use, and these have all increased the convenience of user.
