Abstract

A kind of spring walking aid, by Compress Spring and upper and lower guide post, tightening belt and special leather shoes forms, the female thread at its Compress Spring two ends and upper, the thread segment of lower guide post is connected and fixed, upper guide post forms chain connection with the belt of tightening of tightly pricking under ischial tuberosity, lower guide post is through the end with holes ear outstanding on special leather sole, form the deformation constrain of Compress Spring, and will step on ground pressure by the auxiliary foot realization of stretching out end and transfer to ischial tuberosity, not only obtain leg muscle and the stressed beneficial effect in joint while alleviating walking, also in the release of spring potential energy, obtain the power that promotion moves ahead, reach walk help effect.

Description

Spring walking aid

Technical field

This utility model one spring walking aid, belongs to medical auxiliary apparatus field, the particularly fair patient's of gait control function auxiliary walking, and being intended to provides a kind of Novel rehabilitation equipment for middle-aged and elderly people.

Background technology

People stepped into after old age, because osteoarthrosis and muscle tendon degeneration change, arterial occlusion causes intermittent claudication etc., had more existing walking disorder.Be various canes (comprising crutch, walking stick and elbow cane) and non-motor-driven walking aid (include wheel and without wheel walking frame) be all intended to alleviate body weight with instrument supports power, auxiliary gait stability and walking, but they all occupy arm, make troubles.

The purpose of this utility model is: for numerous gait control functions fair, but the patient of the longer distance of can not freely walking, a kind of device that utilizes Compress Spring the part centrifugal force that acts on lower limb to be transferred to ischial tuberosity is provided, substitutes a cane, reach auxiliary walking effect.

Summary of the invention

This utility model is structurally divided into three parts, Compress Spring and guide post, be fixed on and tighten belt and special leather shoes under ischial tuberosity.

Schematic diagram of the present utility model is (left lower limb) as shown in Figure 1.In figure, (3) represent Compress Spring, are main elements of the present utility model, wherein (3a) and (3b) be spring steel wire compact winding section, do not participate in compression, but form female thread, (3b) section is this spring compressible portion.At both ends of the spring, guide post (2) and lower guide post (4) are housed respectively, upper and lower guide post is except outer end is distinguished to some extent, and other shape is identical, is cylindric, by engineering plastics injection mo(u)lding.Upper and lower guide post in Fig. 1, assorted some filling part diameter is less, and end is hemispherical, can in spring, freely intert, unlikely unstability while guaranteeing Compress Spring distortion; Lycoperdon polymorphum Vitt filling part diameter is larger, and is threaded, and the compact winding section of energy precession Compress Spring, is fastenedly connected itself and spring.Upper guide post outer end is flat, and with the less U-shaped port that closes up, can buckle (0) with the hinge of tightening the upper riveted joint of belt (1) and form chain connection.Tighten belt tight prick thigh root near ischial tuberosity under, the upward force producing while making Compress Spring distortion is applied in ischial tuberosity by tightening belt, is the medium that shifts lower-limb load in walking.Hinge is buckled the chain connection forming and is not only the application point that shifts lower-limb load, makes Compress Spring swing with thigh attitude while also guaranteeing walking, and its function class is like an artificial femoral joint.Lower guide post can form fastening being threaded with spring lower end equally, but its end is shaped to auxiliary foot (7), and it is consistent with true foot to adjust when mounted its direction.After integral installation, at spring, not by compression under situation, auxiliary foot should be than the low suitable compress variation of sole, and this deflection determines that walking aid subtracts power effect.In fact, for making the auxiliary foot drive compression spring on lower guide post, produce and subtract power effectiveness, also must be subject to necessary constraint.This constraint is from a end with holes ear (6) outstanding on sole, and lower guide post is realized screw threads for fastening by the hole precession Compress Spring of this end ear just, and assembly after making to connect only retain one along spring shaft to degree of freedom.Special leather shoes (5) in this utility model, on the space between heel of a shoe and heelpiece, the material global formation with heel of a shoe has leant out the end with holes ear just, becomes the necessary parts of this walking aid.

Walk help effect of the present utility model is achieved in that in walking, when one leg lifts, Compress Spring (3) does not all stress together with upper guide post (2), lower guide post (4), has spring members only along a little rotation of tightening belt hinge and buckle (0); After auxiliary foot (7) lands, body weight makes Compress Spring (3) distortion by lower guide post (4), its resilience force is by upper guide post (2) and tighten the chain connection of tightening belt (1) under ischial tuberosity, act in ischial tuberosity, be equivalent to part and alleviate this leg muscle and the suffered power (roughly the same leaning on the power that crutch is economized) of osteoarthrosis while walking, and in the time that this lower limb lifts because realization moves ahead, power that spring discharges its distortion generation realizes and promotes (this process can not occur in the time leaning on crutch) lower limb forward again.This body weight that utilizes does work in advance to Compress Spring, not only obtains leg muscle and the stressed beneficial effect in joint while alleviating walking, also in the release of spring potential energy, obtains the power that promotion moves ahead, and must reach walk help effect.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model, wherein:

(0)--riveting button hinge; (1)--tighten belt; (2)--upper guide post; (3)--Compress Spring; (4)--lower guide post; (5)--special leather shoes; (6)--the end with holes ear; (7)--auxiliary foot.

Detailed description of the invention

Exemplary embodiments of this utility model as shown in Figure 1,1.80 meters of adaptation person's heights, long 62 centimetres of Compress Spring, 25 centimetres of the each length of guide post (only counting bar-shaped cylinder), 16 millimeters of spring inside diameters, 1.8 millimeters of steel wire diameter, each 8 centimetres of two ends close-packed section length, 3.6 millimeters of compressible portion pitch, material and the trade mark are stainless steel spring steel wire SUS316-WPA, auxiliary foot stretches out 3 centimetres, sole.Through measuring and calculating, when auxiliary foot step on completely into time (3 centimetres of total deformations), the bounce that this Compress Spring produces is 18 kilograms, is applied to tightens in belt and ischial tuberosity completely.Trier left and right lower limb is respectively worn a set of, and after of short duration adaptability exercise, reflection feels that walking is easily laborsaving really, does not feel inconvenient.

Special instruction, for example, for the patient who has gait control dysfunction (, knee joint, femoral joint are undermined cerebral apoplexy sequela), can not be used separately this walking aid, should consider separately to join a cane.
