Abstract

The utility model provides a power-assisted walking aid, which is additionally provided with a torsional spring on the basis of the knee pseudo joint of the original walking aid, and the torque of the torsional spring can support limbs to squat slowly and store elasticity; the elastic supporting force can maintain the squatting position for a longer time; when the limb support device is erected, the rebound force of the spring can support and bounce the limb to easily stand up. The beneficial effects are as follows: when a patient squats, the torsion of the torsion spring in the booster can support the limbs to squat slowly and store elastic force; the elastic supporting force can maintain the squatting position for a longer time when the squatting position is used; when the device is erected, the rebound force of the spring can support and bounce the limbs to easily stand up, and the device has good social and economic significance.

Description

Power-assisted walking aid

Technical Field

The utility model relates to a rehabilitation assisting device, in particular to a power-assisted walking aid device which is inconvenient to walk and is accompanied with the weakness of flexion and extension.

Background

Various walking aids (including an authorized utility model patent: a novel walking aid replacing a crutch and a knee joint fixing brace, patent number: 201520001795.8) produced by our company all aim at solving the problem of walking inconvenience, and the products have the common characteristics of portability, comfort, economy, durability, strong adaptability, wide adaptation diseases, excellent effect, wearing in trousers and out of underpants, protecting the dignity of people to the maximum extent, and being highly approved by society and patients after being pushed out. However, in use, it is found that a large number of patients with limb and knee joint weakness in the people who are inconvenient to walk show pain, do not need to exert strength, can reluctantly complete the actions only by the auxiliary traction or support of the upper limbs in the similar activities such as going upstairs and downstairs, squatting and standing, and the joint replacement operation is mature in the long term and has high cost and occasional sequelae after the operation, which are often prohibited by people. In view of the above, the inventor of the invention provides a power-assisted walking aid for performing rehabilitation assistance treatment on patients who have walking inconvenience and have knee weakness.

SUMMERY OF THE UTILITY MODEL

The utility model provides a booster walking aid device for solving the problems existing in the prior art.

The technical scheme of the utility model is realized like this:

the walking aid sequentially comprises a thigh supporting sheet, a power-assisted knee pseudo joint, a shank upper supporting sheet, an adjuster, a shank lower supporting sheet, a pedal, a fixing belt, an auxiliary fixing belt and a lining, wherein a torsion spring is arranged on the power-assisted knee pseudo joint.

The power-assisted knee pseudo joint is formed by riveting the thigh supporting sheet, the upper crus supporting sheet and the torsion spring through rivets, the lower end of the thigh supporting sheet and the upper end of the upper crus supporting sheet are both circular joints, shaft holes are formed in the circle centers of the two circular joints, the centers of the torsion springs are fixed on the outer sides of the two circular joints, spring arms of the torsion springs extend towards the two opposite surfaces, and the two spring arms are clamped at the rear parts of the bending parts of the circular joints; the number of turns of the torsion spring is not more than two.

And a gasket is arranged between the rivet cover at the end part of the rivet and the torsion spring.

The utility model has the advantages that:

1. the structure is simple, and the use is light and comfortable; 2. the control is automatic, when the patient squats, the torsion of the torsion spring in the booster can support the limb to squat slowly and store elasticity; the elastic supporting force can maintain the squatting position for a longer time when the squatting position is used; when the limb support device is erected, the rebound force of the spring can support and bounce the limb to easily stand up; 3. provides a practical and reliable rehabilitation auxiliary device for patients who have walking inconvenience and have difficulty in squatting and standing up; 4. has good social and economic significance.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in figures 1-2, the walking aid comprises a thigh supporting sheet 1, a power-assisted knee pseudo joint, a shank upper supporting sheet 2, an adjuster 3, a shank lower supporting sheet 4, a pedal 5, a fixing belt 6, an auxiliary fixing belt 6 and a lining, wherein the thigh supporting sheet 1 and the shank upper supporting sheet 2 are riveted through a rivet 7, a torsion spring 8 is arranged on a rivet 7 of the riveting structure to form an assisted-reset knee pseudo-joint structure, the lower end of a lower leg supporting piece 4 is inserted into an opening on the lower side surface of the adjuster 3, the adjuster 3 is arranged at the lower end of the upper leg supporting piece 2, the lower ends of the pair of lower leg supporting pieces 4 are provided with pedals 5, the folded parts at two sides of the pedals 5 are hinged with the lower leg supporting pieces 4, the fixing belt 6 and the auxiliary fixing belt 6 are used for fixing the walking aid on the legs of a patient, and the lining can increase the wearing comfort.

The power-assisted knee pseudo joint is formed by riveting a thigh supporting sheet 1, a shank upper supporting sheet 2 and a torsion spring 8 through a rivet 7, the lower end of the thigh supporting sheet 1 and the upper end of the shank upper supporting sheet 2 are gradually bent and extended into a circular joint 9 according to the appearance of a knee joint part, a shaft hole is prepared at the circle center of the two circular joints 9, the center of the torsion spring 8 is fixed at the outer sides of the two circular joints 9, and a spring arm of the torsion spring 8 extends towards the two sides of the thigh supporting sheet 1 and the shank upper supporting sheet 2 and is clamped at the rear part of the extending and bending part of the circular joint 9; the number of turns of the torsion spring 8 does not exceed two turns.

The torsion spring 8 can be selected into a proper model according to the requirements of the movement gravity of patients with different weights; the free degree of motion of the double-spring arm of the torsion spring 8 is between 130 and 150⁰In the meantime.

A gasket is arranged between the rivet 7 cover at the end part of the rivet 7 and the torsion spring 8, so that the friction between the torsion spring 8 and the rivet 7 is reduced.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
