Description

A spring-loaded get-up linkage device

technical field

The present invention relates to a spring energy storage linkage device for getting up.

Background technique

"Portable and Wearable Assisted Standing Up Chair" is a seat suitable for the vast majority of the elderly to travel. Provides a safe, reliable and convenient seat. With the development trend of total expansion and incremental increase in the scale of the elderly population in my country, the population support burden is gradually increasing, and the travel safety of the elderly has become the focus of social attention. Many elderly people always need to carry a small bench or a crutch stool that is common in the market when they go out, which is relatively heavy; and some elderly people with bad legs and feet often cannot find a suitable seat, and many elderly people struggle to get up after sitting down. ; Public seats in the society still lack humanized design for the elderly. However, the existing seat lifting devices are divided into two categories, one is driven by a screw rod:

Due to its own strength, the ordinary screw is not easy to bear the axial and lateral forces, and it is difficult to assume the role of standing up, and it cannot realize the lifting of the handrail, which also helps to get up. The multi-stage transmission of each gear plays the role of assisting getting up, and can also ensure the lifting of the armrest, but it is not suitable for wear due to too many parts, occupying a large space and difficult to match.

SUMMARY OF THE INVENTION

In view of the above problems, the present invention proposes a simple and ingenious structure that links multiple auxiliary standing structures together to superimpose a standing effect, enhances functionality, and greatly reduces the occupied space caused by adding multiple structures. A spring-charged riser linkage for heavy weight issues.

The spring energy storage linkage device for getting up according to the present invention is characterized in that it includes a getting up plate, a handrail and a getting up linkage assembly, and the getting up linkage assembly includes a first connecting rod, a second connecting rod, a third connecting rod and Spring, the first connecting rod, the second connecting rod and the third connecting rod are hinged in sequence to form a rod body, and the rod body has two ends, one end is used as the energy storage end and is hinged with the rising plate, and the other end is used as the linkage end and the armrest The connecting end of the spring is hinged; the spring is arranged at the bottom of the lifting plate, wherein the upper end of the spring is connected with the third connecting rod, and the lower end is connected with the external support frame as a supporting end, which is used to realize the conversion between the kinetic energy of the lifting plate and the elastic potential energy of the spring.

The upper part of the armrest has a block for grasping and a support surface for applying force.

The upper end of the spring is connected to the hinge joint between the third link and the riser plate, and when the riser plate is in a horizontal state, the spring is in a compressed state.

The first end of the third link is connected to a spring, the second end of the third link is hinged with the first end of the second link, and the second end of the second link is hinged with the first end of the first link , the second end of the first connecting rod is hinged to the lower part of the armrest, wherein the first connecting rod, the second connecting rod and the third connecting rod are hinged to form a folding rod.

When the elderly sit down, the riser plate is rotated to store the potential energy of the spring. When the elderly have no tendency to get up, the spring is still in a compressed state. The connecting rod and the third connecting rod rotate, and at the same time, the spring gradually releases the elastic potential energy, which together play the role of assisting the elderly to get up. The elderly generally need the support of the armrest to get up. Therefore, in the design of the assisting device, the armrest support is used to drive the connecting rod and the elastic potential energy release of the spring to play an auxiliary role in getting up, which can solve the problem of getting up for the elderly.

The beneficial effects of the present invention are: a structure for assisting getting up is designed through practice, the spring potential energy can be stored when the elderly sit down, and the spring is still in a compressed state when the elderly have no tendency to get up. When getting up, the armrest will be supported to cause the linkage system to rotate together, and the spring will gradually release the elastic potential energy, which together play the role of assisting the elderly to get up.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

Referring to the attached drawings:

Embodiment 1 A spring energy storage linkage device for getting up according to the present invention includes a getting up plate 1, a handrail 2 and a getting up linkage assembly 3. The getting up linkage assembly 3 includes a first connecting rod 31, a second connecting rod 32, The third connecting rod 33 and the spring 34, the first connecting rod 31, the second connecting rod 32, and the third connecting rod 33 are hinged in sequence to form a rod body, and the rod body has two ends, one end serves as the energy storage end and the stand-up end The board 1 is hinged, and the other end is hinged with the connecting end of the handrail 2 as a linkage end; the spring 34 is arranged at the bottom of the rising board 1, wherein the upper end of the spring 34 is connected with the third connecting rod, and the lower end is connected with the external support frame as a supporting end, for Realize the conversion between the kinetic energy of the lifting plate and the elastic potential energy of the spring; since the angle of the lifting plate is the same when it reaches the limit position, the angle of the final armrest will also be fixed.

The upper part of the armrest 2 has a block for grasping and a support surface for applying force.

The upper end of the spring 34 is connected to the hinged joint between the first end of the third link 33 and the riser plate 1 , and when the riser plate is in a horizontal state, the spring is in a compressed state.

The first end of the third link is connected to a spring, the second end of the third link is hinged with the first end of the second link, and the second end of the second link is hinged with the first end of the first link , the second end of the first connecting rod is hinged to the lower part of the armrest, wherein the first connecting rod, the second connecting rod and the third connecting rod are hinged to form a folding rod.

When the elderly sit down, the riser plate is rotated to store the potential energy of the spring. When the elderly person has no tendency to rise up, the spring is still in a compressed state. Armrest: The first end of the third link moves downward under the pressure of the riser plate. , thereby driving the second end of the third connecting rod to rise, thereby making the second connecting rod hinged with the third connecting rod rise, and driving the first connecting rod to rise, so that the lower end of the handrail not only rises in the vertical direction, but also rises in the horizontal direction. Move, so that the armrest is transformed from the horizontal storage state to the vertical armrest state. When the elderly have a tendency to get up, the handrail drives the first link, the second link and the third link to rotate, and the spring gradually releases the elastic potential energy to assist the elderly to get up. The elderly generally need the support of the armrest to get up. Therefore, in the design of the assisting device, the armrest support is used to drive the connecting rod and the elastic potential energy release of the spring to play an auxiliary role in getting up, which can solve the problem of getting up for the elderly.
