Description

Portable double walking stick

The invention belongs to the health care apparatus, a kind of portable double walking stick of more specifically saying so with effect of new control method and Telescopic and health care thereof.

High speed development along with the requirement of era development and the raising of people's living standard, the particularly vehicles; The disabled user utmost point is waited to look forward to a kind ofly to use and carry all very easily that the double walking stick product comes out early, and this hope is especially at the user of developed country, and is more outstanding.But up to the present, do not find to satisfy the new generation product of this requirement in the international market as yet.

The objective of the invention is to and will address the above problem, provide a kind of have telescopicing performance, but use very simple, and double walking stick with health role; Can alleviate the physiological load of the disabled user of wide model thus, satisfy their eager desire simultaneously.

Task of the present invention is finished as follows:

One, simple Telescopic the invention provides a kind of, mainly the Dan Lizhu that forms by the type pipe or (with) a plurality of (minimum 3) integral units of two power column type structure kenels cooperatively interacts and connects formed adjustable movable machine-operated (seeing Fig. 1,2) at length direction.It is characterized in that: between the integral unit (being between the type pipe), be from top to bottom, order phase mutual energy from big to small packs into, but can not rotate (ignoring the relative rotation that is caused by fit clearance) relatively; Connect between them is to be used for the axle that is subjected to spring force that passes to symmetrical holes from the amphitypy caliber or realize from the bearing pin that is subjected to spring force that the inside type pipe wears out.

At above-mentioned adjustable movable office, the present invention requires: when axle with the spring action force opposite direction is drawn out to a certain degree or the part bearing pin by the people for pin enter in the type pipe mobile to a certain degree, when two of crutch applied the certain pressure (this effect the present invention cries " pressure effect ") that tightens inward, whole office can realize dwindling relatively to greatest extent fully then; When pressure became the opposite pulling force of its direction (this effect the present invention cries " pulling force effect "), whole office fully can the reinstatement attitude.Because the axle or (with) bearing pin is done relative motion back and forth in completely specified liner mark length, so they under the effect by spring pressure, all can find the position of oneself leaving, original hole in backhaul.

In the process of dwindling, the action principle (see figure 5) that makes each bearing pin (except that being the bearing pin of pinning by the people) pass through smoothly the various obstacles that run into is: the axial component F of the F that produces between bearing pin and barrier ₁(＞P+f, P are spring pressure, and f is a frictional force) enters in the type pipe bearing pin and moves.The present invention is to the bearing pin of peacetime state, and the effect that applies axial component is " assistant's effect "; To the bearing pin in the type pipe, apply the heavy effect of axial branch " automatism ".

Two, the type tubular construction of the existing double walking stick of new control method except a bottom nodal pattern pipe is that to be used for regulating crutch leg long and be designed to the bascule of adjustable (or removable), all belongs to changeless dead frame.Therefore, be used for mobile handgrip position on damned, light when regulating, brings influence to crutch leg long (representing with L) in the middle of being not intended to crutch arm long (representing with l), that is: when l increased (handgrip moves down), then L reduced on the contrary; Otherwise then strengthen on the contrary.Trend is regulated in this variation ratio between l and L just the opposite, is the fatal obstacle in the adjusting.

The present invention provides independently regulating separately of the relation of having no effect between a kind of l of adjusting and L machine-operated in order to solve above-mentioned disadvantage.If in certain height scope, the l/L value can be similar to regards constant constant K, i.e. a K=l/L as; According to above-mentioned two kinds of conditions, the coordination proportionate relationship formula between crutch arm after regulating and lower limb are long can be expressed with following formula so:

K=l ± h/ (L  h) ± (1+K) h (to existing double walking stick)

K=l ± h/L ± kh (to the present invention)

In the examination, h is for regulating height.By contrast, the little 2h height of the range of accommodation of existing procucts.This just why the products of many countries such as U.S. generally all be the basic reason that satisfies user by two kinds of length specifications.

Three, vibration damping overcoat (1) plays following effect in the process of the body of the effect user of health care dependence bearing support (2):

1. the cushioning effect that plays when carrying out stretching motion on the spatial altitude of vibration damping overcoat (1) in space (27) of being made by elastomeric material is characterized in that: vibration damping overcoat (1) inboard has additional vibration damping band (28).This cushioning effect can not only alleviate the pain of armpit, and can prevent life-time service the shoulder that may cause deformity such as heave, bend over change.

2. the air in space (27) is compressed simultaneously and flows out the outside by air vent (29), therefore, brings nice and cool, comfortable sensation can for the armpit of user in hot day.

The present invention compares (under the same height condition) its advantage with the Americanized up-to-date double walking stick product of " GUARDIAN " board:

1. because of adopting new control method, the range of accommodation of eurythmy is expanded to about 1.5 times.Therefore, two kinds of length specifications can be unified a kind of specification, reach general purpose.

2. have Telescopic, but manipulate very simple; Minification reaches about 43%, so the travelling that is easy to carry very much.

3. under the same user condition, good buffer effect; Use in hot day simultaneously and have refrigerant effect.
