Auxiliary chair

This creation is about a chair, especially about an auxiliary chair with an auxiliary function.

In general, when you get up from a chair, you need to use the strength of the lower limbs and the spine to support the movement. For the elderly, the lower limbs, or the person with the spine, the lower limbs are not strong enough to be as smooth as the average person. Get up in a sitting position. Therefore, there is a chair on the market that can assist in getting up.

The conventionally assisted chair can be provided with a seat cushion and a base disposed under the seat cushion, and an elastic member is disposed between the seat cushion and the base. When the user sits on the seat cushion, the elastic member disposed between the seat cushion and the base is compressed to accumulate elastic force. When the user gets up and the buttocks slightly leave the seat cushion, the elastic force accumulated by the elastic member can cause the seat surface of the seat cushion to rebound in the direction of the user, and push the user upward and forward to assist the user to get up. .

However, since the elastic force of the elastic member cannot be adjusted, if the user's weight is heavy, the elastic force accumulated by the elastic member may be insufficient to rebound effectively, so that the effect of assisting the lifting is limited. If the user's weight is light, the elastic force of the elastic member may be too large, and the user may be pushed up quickly to cause danger. For a lighter weight user, there may even be cases where the elastic force of the elastic member cannot be overcome, and the elastic member cannot be compressed. In this case, the user will be completely unable to use the chair that is assisted to get up.

Although manufacturers can make auxiliary chairs with elastic elements with different elastic coefficients to provide users with different weights. However, if a family has a plurality of different weight users who need to assist in getting up the chair, and the users have different weights between each other, it is necessary to have a plurality of auxiliary chairs having different elasticity. In this case, in addition to taking up space, it is more inconvenient to use, and it is quite inconvenient to use.

Therefore, how to provide an auxiliary chair that can be adjusted according to users of different body weights to assist the user in getting up is one of the problems that need to be solved in the art.

In view of the above problems, the purpose of the present invention is to provide an auxiliary chair which can assist the user to complete the lifting movement and can be adjusted according to users of different body weights, so as to be suitable for users of different body weights.

When the user rides on the seat cushion 13 of the embodiment, the seat cushion 13 can be pressed downward by the weight of the user, as shown by the direction of the hollow arrow shown in FIG. 3, so that the elastic support member 15 is compressed, and At this time, the elastic support member 15 gradually accumulates the elastic force. In addition, the two ends of the elastic support member 15 are respectively pivotally connected to the first adjusting portion 141 and the second adjusting portion 142, so that the first adjusting portion 141 and the second adjusting portion 142 can be close to each other without an angle therebetween. (ie, the two are parallel or overlapping), as shown in Figure 3.

When the user wants to get up, he only needs to leave the seat cushion 13 slightly. When the force applied by the user to the seat cushion 13 is less than the elastic force accumulated by the elastic support member 15, the elastic support member 15 can be released from the compressed state. Pushing the seat cushion 13 in turn assists the user in getting up. In other words, the seat cushion 13 of the present embodiment can use the weight of the user to compress the elastic support member 15 and convert the accumulated elastic force into a force for assisting the user to get up, so that the user can get up in a relatively easy and labor-saving manner.

Please refer to FIG. 4 again, which is a schematic diagram of the auxiliary chair shown in FIG. 1A in different states. Compared with the state shown in FIG. 2, the elastic support member 15 shown in FIG. 2 can accumulate a large elastic force due to a long compression stroke, and can provide a large thrust force, so that it can be applied to a heavy weight use. By. On the other hand, if the user's weight is light and the first end 15a of the elastic support member 15 is still disposed in the recess of the first compartment as shown in FIG. 2, the user may not be able to overcome the elastic force accumulated by the elastic support member 15. Further, the seat cushion 13 cannot be pressed down, or when the body is raised, the elastic force accumulated by the elastic support member 15 is excessively large, causing the user to be in a dangerous situation such as forward diving. At this time, the first end 15a of the elastic support member 15 can be placed in the recess of the last compartment as shown in FIG. 4, so that the elastic force which can be accumulated by the elastic support member 15 is smaller than that shown in FIG. The lighter weight user overcomes the elastic force accumulated by the elastic support member 15 to meet the needs of a lighter weight user.

Please refer to FIG. 5 , which is an illustration of the chair of the auxiliary chair shown in FIG. 1A being adjusted. intention.
