Abstract

The utility model discloses a balanced sliding stick, comprising a horizontal supporting rack, a supporting bar and a movable bracket. The movable bracket comprises a pair of long components and a pair of short components. The lower ends of the long components are respectively provided with a unidirectional wheel which is sheathed without loosing on the lower end of the supporting bar of the stick through a bolt and a lantern ring. The two short components are also pin-connected by bolts; one end as touch-down point is also provided with a unidirectional wheel, and another both ends are respectively pin connected with the mid-point location of the two long components by bolts. In this way, the upper parts of the two short components and the two long components just compose a parallelogram frame. A spring is installed on the longitudinal diagonal of the parallelogram frame. The stick is foldable, is suitable to be used on smooth ground without lifting and moving, and is adapted for people of heavier disability degree to use.

Description

Balanced sliding formula crutch

Technical field

This utility model relates to a kind of crutch for invalid, particularly a kind of balanced sliding formula crutch.

Background technology

The crutch that disabled people support usefulness is used till today and existingly century-oldly, and style still generally is made up of horizontal support and support bar, need to overcome the crutch own wt when people with disability is current and move forward with portable crutch, about intersection, could walk forward.For the lighter people of some degree of disability, difficulty is little; But, just move relatively effort for the heavier people of some degree of disability.

Summary of the invention

The purpose of this utility model provides a kind of when leaning on crutch and walking, and neither lifts, and does not move the position again, the novel crutch of balanced sliding.The purpose of this utility model is achieved through the following technical solutions, lower end at former crutch, a travel(l)ing rest has been installed, this travel(l)ing rest is made of two pairs of symmetrical in twos flat members, a pair of length, a pair of weak point, short length is approximately 1/2nd of long length, two long member lower end touchdown points are respectively installed an one-way wheel, by bolt and the not loosening lower end that is sleeved on the crutch support bar of the collar, the member of two weak points also uses the bolt bolt tight, end as touchdown point is also adorned an one-way wheel, two ends are respectively with the point midway of bolted-on at the member of two length in addition, and parallelogram lever of the lucky formation of the first half of the member of such two weak points and two long members is adorned a spring on the horizontal diagonal of parallelogram lever.During use, when axillary fossa pressed down, the parallelogram transverse extension because wheel can only one-directional rotation, made the crutch reach, and when axillary fossa pressure disappeared, spring restored parallelogram lever, and crutch is moved forward, and moved in circles, thereby slided forward.

Description of drawings

Figure is a structural representation of the present utility model.

The specific embodiment

As shown in the figure, this utility model is made of horizontal shore 1 and support bar 2 and a travel(l)ing rest, this travel(l)ing rest by the member 3 of a pair of length and 4 and the

member

5 and 6 of a pair of weak point form.An one-way wheel 7 is respectively installed in

long member

3 and 4 lower end, by bolt 8 and the collar 9 tight lower ends that are sleeved on the crutch support bar, the

member

5 and 6 of two weak points is also used bolted-on, end as touchdown point also is equipped with an one-way wheel, and the point midway of bolted-on at two long members used at two ends respectively in addition.Like this, the member of two weak points and two long member the first half constitute a parallelogram lever just, adorn a spring 10 on the horizontal diagonal of parallelogram lever.This crutch is collapsible, is adapted at using on the smooth earth, need not lift and move the position, is suitable for the heavier people of degree of disability and uses.

Claims

1, a kind of balanced sliding formula crutch, by horizontal shore (1) and support bar (2) and a travel(l)ing rest formation, it is characterized in that this travel(l)ing rest is made up of the member (3) of a pair of length and member (5) and (6) of (4) and a pair of weak point, an one-way wheel (7) is respectively installed in the long member (3) and the lower end of (4), by bolt (8) and the tight lower end that is sleeved on the crutch support bar of the collar (9), bolted-on is also used in the member of two weak points (5) and (6), end as touchdown point also is equipped with an one-way wheel, the point midway of bolted-on at two long members used at two ends respectively in addition, like this, the member of two weak points and two long member the first half constitute a parallelogram lever just, adorn a spring (10) on the horizontal diagonal of parallelogram lever.
