Technical Field
The utility model relates to an adaptation is used for wearing formula along with device of getting up of seat.
Background
The 'portable wearable auxiliary rising assisting and following chair' is a chair suitable for the traveling of the majority of old people at present, is convenient for smoothly and freely complete the simple actions of 'sitting down' and 'rising up', and provides a safe, reliable and convenient chair for the old people. With the development situation that the population scale of the elderly in China shows total expansion and increment acceleration, the population fostering burden is gradually strengthened, and the travel safety problem of the elderly becomes the focus of social attention. Many old people always need to carry a small stool or a common walking stick stool on the market when going out for activities, and the walking stick stool is heavy; some old people with bad legs and feet often cannot find a proper seat, and many old people get up and get hard after sitting down; the public chair in the society is lack of humanized design for the old. Although portable chairs are available on the market, some wearable external bones on the market generally have the following problems when worn on human bodies: 1) the weight is too heavy, so that normal walking is influenced when a person wears the garment; 2) the sitting and standing function can be realized, but the normal posture of a person during normal walking can be seriously influenced by the gas spring; 3) electromagnetic control is easier to implement, but because the work is considered wearable, the weight of the motor can affect human comfort. Meanwhile, electromagnetic control may cause leakage problem, and potential safety hazard exists.
Disclosure of Invention
In order to solve the problem, the utility model provides a supplementary device of getting up, can be used for wearing formula along with the seat that the shank is crooked, does not influence normal walking of fine adaptation shank.
A device of getting up for wearing formula along with seat, its characterized in that: the lifting driving mechanism comprises a gas spring and a connecting piece, wherein an installation part of the gas spring is hinged to the rear part of the shank supporting frame, and a telescopic part of the gas spring is detachably arranged at the lower part of the shank supporting frame through the connecting piece; drive mechanism includes the first body of rod, the second body of rod and three-dimensional universal joint, the upper end and the thigh support frame lower extreme rigid coupling of the first body of rod, the lower extreme of the first body of rod pass through the three-dimensional universal joint with the upper end of the second body of rod links to each other, the lower extreme of the second body of rod and the upper end rigid coupling of shank support frame, when wherein the air spring links to each other with the thigh support frame, the first body of rod, the second body of rod and air spring form triangle-shaped bearing structure.
The lower part of thigh support frame is equipped with the spout that the pars contractilis card that is used for air feed spring is gone into, and the spout comprises the axial groove that sets up along thigh support frame axial and the card income groove that extends to thigh support frame border, and wherein the pars contractilis of air spring passes through the lower part sliding connection of connecting piece and thigh support frame for the pars contractilis of supplementary mechanism of standing up moves along the axial groove.
The connecting piece is a U-shaped buckle.
The stepping mechanism comprises a connecting piece and a pedal, wherein the upper end of the connecting piece is hinged with the lower end of the shank support frame, and the lower end of the connecting piece is hinged with the pedal.
The pedal is of a U-shaped structure, and the groove in the middle of the U-shaped structure is used for placing a foot; two walls of the groove are respectively provided with a connecting sheet, the lower end of the connecting sheet is hinged with the wall of the groove, and the connecting sheet is axially provided with a plurality of positioning holes for being hinged with the lower end of the shank support frame.
The two connecting pieces are respectively positioned at two sides of the shank and are hinged with the lower end of the shank support frame through positioning pins.
When in work: in the process of normal walking of a person, a certain angle is formed between the thigh and the shank, and if the thigh and the shank are directly connected through the gas spring, the posture of the old person in normal walking is affected. Therefore, the sliding groove structure is designed at the position where the thigh is connected with the gas spring, the purpose is that the angle of the normal big leg and the small leg of the old man can not be affected by the force of the gas spring in the walking process, but when the old man is ready to sit, the angle of the big leg and the small leg is increased to a certain angle, the gas spring is in a blocking state, and the supporting effect is achieved.
When a person stands, the air spring is at the maximum stroke position, the joint of the air spring and the thigh support frame is the tail end of the axial groove of the sliding groove, and the connecting piece is connected with the telescopic part of the air spring, so that the person can be conveniently picked. When a person sits and stands, the gas spring moves to the top end of the sliding groove along with the change of the angle between the big leg and the small leg and the connection position of the thigh supporting frame. At the moment, the gas spring starts to exert force on the thigh of the person to play a supporting role, and a chair is formed. Therefore, the person can walk normally without being influenced by the force of the gas spring, and the normal walking of the person is not influenced.
The installation length of the connecting sheet is adjusted according to the height of a user, so that the device is suitable for people with different heights.
The utility model has the advantages that: the problem that the normal walking of people is influenced can appear when using gas spring helping hand, so this time we design the spout of certain length and make the people not receive the power of air spring at the in-process of normal walking to and design ankle slewing mechanism and adapt to people's normal sole and rotate and the crowd of adaptable different heights.
