Abstract

Disclosed is a four-foot walking stick capable of lowering stumbling risks of an old person. Four supporting feet extend out from four corners of a column foot plate outwards and include three fixed supporting feet and a movable supporting foot, and the movable supporting foot rotating around a vertical shaft on the column foot plate is arranged at the corner closest to the foot of the person and usually stops at a position butting against a retaining column under the action of a rotary spring. When the walking stick falls to the ground, because of geotropic gravity, the movable supporting foot can only move horizontally, and the walking stick can bear force from top to bottom; when the old person carries the walking stick to go forward, the foot of the old person with the body most instable kicks the movable supporting foot, at the moment, the movable supporting foot is free of ground friction, and accordingly, horizontal resistance of the movable supporting foot is insufficient to stumble the old person. Since a roller can be arranged at a grounding position of the movable supporting foot, except for time nodes when the old person is easy to stumble, when the four-foot walking stick is placed flat downwards and the old person kicks the movable supporting foot, friction force between the movable supporting foot and the ground can be decreased under the action of the roller, kicking resistance is also decreased, and further, the stumbling risks of the old person can be minimized maximally.

Description

A kind of quadropods reducing old man's trip hazards

Technical field

The present invention relates to nursing device field, specifically a kind of quadropods reducing old man's trip hazards.

Background technology

It is known that old man, in order to not fall, often uses crutch in walking, and quadropods has four fixing spikes, four The heel slab of the upper end of individual spike and cane post bottom connects, bottom as by holding cane people towards in direction, then towards front left, front right, Rear left, rear right four direction stretch, and are landed by four Anti-slip covers, because it is supported in ground as four feet of stool, Therefore old man pins crutch when walking and is difficult to rock, and this quadropods has almost become the necessary tool of old man's walking now. Be typically all that flat carrying keeps flat when old man is walked with quadropods, for the people of cane is such as held in four spike positions by the right hand, wherein after That spike left from people's foot recently, is also the most easily kicked by the right foot of old man, and in order to not make the too near spike of right foot, the cane post of crutch is always Be contained in heel slab lean on people side, but if by cane post be made from people's foot too close to, it will make cane post support force deviate post Sole center, is sitting in the edge of stool as people, also holds easy to fall down, and the advantage of quadropods does not just exist.Therefore four feet turn Though it has been noted that keeping and people's foot distance during the design of that spike of cane rear left, by being limited by above-mentioned factor, can only be than common Crutch foot from people enough close to many, that spike that some old men are approached people's foot when using quadropods trips, The author parent people that is aged uses and trips process, when old man keeps flat quadropods on ground downwards, because body gravity falls On quadropods, even if foot is to crutch slightly side band, body support also can be lived and will not fall by quadropods；And work as old man When quadropods is lifted, because at this moment crutch the most easily rocks, old man bases oneself upon shakiness, just easily touches closely sufficient support Foot is not although quadropods weighs, but the effect due to grip, and people kicks on spike enough, and bounce is also very big, therefore can make old man Trip.Some old men are exactly that fearness trips and abandons using quadropods, because crutch is once trip old man, weight usually occur Big dangerous situation.Some people just want to buy the crutch being difficult to make old man trip on the net now, but there is no such product in the market.But Old people get more and more, if can create a kind of make old people be difficult the quadropods tripping, highly beneficial beyond doubt.

Content of the invention

The purpose of the present invention is: so that quadropods can be stably supported, is not easy to make old man trip again.

The object of the present invention is achieved like this: it includes a quadropods, and the cane post of quadropods passes through regulation pipe It is fixed on the square heel slab in one piece of bottom, there are four spikes the corner of heel slab, it is characterized in that: except the fixation with Anti-slip cover Outside spike, also near holding on the nearer angle of cane people side foot, it is additionally provided with the movable supporting feet that can horizontally rotate, institute around vertical pivot The vertical pivot stated is fixed on heel slab on the remote position of people's foot outside, is the axle sleeve with lubricating arrangement outside vertical pivot, axle sleeve Can make to horizontally rotate around vertical pivot with the movable supporting feet affixed with it, have rotation spring between axle sleeve and vertical pivot, at ordinary times in the effect of rotation spring Under, movable supporting feet rotates and offsets to the bumping post being fixed on heel slab.

So, movable supporting feet offsets position with bumping post due to resting at ordinary times under the spring force effect of rotation spring, work now Dynamic spike is just distributed in the corner of heel slab together with fixing spike.When old man lifts above-mentioned quadropods and need to advance forward, Crutch can be put down and be carried when keeping flat by general old man, because gravity is to ground, the axle sleeve of movable supporting feet and vertical pivot be can only level to work Dynamic structure, therefore it can bear power from the top down.But when old man carries cane and advances, due to being easiest to during using quadropods Make that old man trips be in old man, crutch is lifted and on the timing node that not yet puts down, at this moment because the advancing foot of old man touches To the movable supporting feet of quadropods, it is by axle sleeve and vertical pivot between the heel slab due to movable supporting feet with staff grip crutch And be slidably connected, this reduces the resistance to people's foot for the movable supporting feet, old man is just difficult to fall.Again due to movable supporting feet Vertical pivot is fixed on heel slab on the remote position of people's foot outside, and this not only makes foot play direction and movable supporting feet rotation direction basic Cause；And foot also can be made according to the principle of lever to play drag reduction because the movable supporting feet length as the arm of force increases；Also have Be also provided with roller at the ground connection of movable supporting feet, such old man in addition to the timing node easily tripping, when quadropods to Under when keeping flat, if the occurrence of old man also kicks movable supporting feet, because the effect of roller can make movable supporting feet and ground Face friction reduces, and resistance when playing enough also will reduce, and so that the risk that old man trips is preferably minimized to greatest extent.
