Abstract

The present invention relates to a chair helping a user to conveniently stand up from the chair, and more specifically, to a hydraulic chair with a foot support using a hydraulic piston connected to a foot support and a chair seat surface. To this end, the present invention comprises: a main body; a foot support portion; and a hydraulic connection portion. When the user pushes the foot support to stand up from the chair, the seat surface is lifted up since the seat surface and the back support are connected via the hydraulic piston, so the user is able to easily stand up from the chair.

Description

Hydraulic footrest chair {omitted}

The present invention is a hydraulic chair that facilitates standing and sitting in a chair. Through the interaction of the chair and the footrest by the hydraulic piston, it strengthens the strength by the synergy of the chair part when standing up. The present invention is largely divided into a hydraulic connecting portion, a main body, and a footrest portion.

In the conventional hydraulic chair, even if there is a footrest, the movement of the hydraulic piston is not interlocked, and the height of the chair can be adjusted by using the hydraulic rod. Elders who have old age often have weak knees and legs, and feel difficulty when they sit down or wake up again. The chair has less positional change than sitting on the floor, so it needs less power when it happens, but it is still a tough activity for people with disabilities.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to make it easier to stand up and sit down by using the up and down movement of the chair portion through the hydraulic piston between the chair portion and the footrest portion.

By using the principle of hydraulic piston, when the force is applied to the footrest, the same force is applied to the chair, thereby helping to raise the chair part. To get up, the user of the chair will apply a force of magnitude to support himself on the footrest. The force of the same magnitude transmitted through the hydraulic piston lifts up the seat so that the weight of the footrest can be reduced to a minimum. For stability when stepping on the footrest, the footrest is made of a wide, flat surface and secured to the ground to ensure support. Apart from the function of helping to occur in the form of both the hydraulic rod and the hydraulic piston, the height adjustment function can be used as it is.

The user of the chair can easily get up with little effort. It relieves the inconvenience when weak users of the knee or leg are raised in the chair.

Fig. 1 is a whole view of the above-described invention viewed from the side.
2 is an enlarged side view of the lower part of the invention.

The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 shows a whole aspect of the invention. The method of using the invention as shown in FIG. 1 is as follows. The user is sitting in a chair and wants to get up. First, when you stand up from the chair, raise your feet on the footrest, which is 20 (a), and lift the weight.

Fig. 2 shows the enlarged side view of the footrest portion in detail. 21 (b) and 23 (b) are wide and flat so that the user can take a large area. The foot support legs 24 (b) below support the user in a stable manner. 22 (b) is a pillar of a footrest made of a hydraulic rod. When the user moves the foot to 21 (b) and presses the force, 22 (b) goes down. 22 (b) is connected to the pillar 13 (b) of the main body through the hydraulic piston 30 (b) so that 13 (b) rises. In this process, the height of the main body chair is increased, which helps the user to get up more easily. As the weight applied to the footrest increases during the course of the process, the chair also continues to rise and continues to help the process.

11 (a) is the backrest part of the chair type body.
12 (a) is the left-hand part of the chair type body.
13 (a) is a column of a chair-shaped body made of a hydraulic rod.
14 (a) is a supporting leg of a chair-shaped body.
20 (a) is a hydraulic footrest.
30 (a) is a hydraulic piston connecting the chair type body and the hydraulic footrest.
21 (b) is the top plate of the hydraulic footrest.
23 (b) is the bottom plate of the hydraulic footrest.
24 (b) is the supporting leg of the hydraulic footrest.
22 (b) is a pillar of a hydraulic footrest consisting of a hydraulic rod.
13 (b) is 13 (a) at the time of looking at the enlarged side.
30 (b) is 30 (a) at the time of magnifying and looking at the side.
