Description

foldable telescoping seat

technical field

The invention relates to a piece of furniture, which is a foldable telescopic seat.

Background technique

Seats are indispensable household appliances in people's lives. There are a variety of foldable or retractable seats on the market, but there are not many foldable and retractable seats, and many The type of seat structure is too complicated, difficult to manufacture and process, and the cost is high. There are not many products used by ordinary people or the functions are too single.

Contents of the invention

Aiming at the disadvantages of existing seats, the purpose of the present invention is to design a foldable and telescopic seat with variable size, convenient storage and adjustment, and meeting the needs of different groups of people.

In order to achieve the above object, the present invention adopts the following technical solutions:

The foldable telescopic seat is mainly composed of a bracket part, a seat cushion part, a back board and an eccentric hexagonal cam. The bracket part includes a telescopic bracket, a main back bracket, a main bracket column, a seat rear leg, a support column, a seat front leg and a support ring, the telescopic bracket forms a sliding connection with the main back bracket, and the main back bracket The bottom is provided with a main support column, which is movably linked with the rear legs of the seat. The rear legs of the seat are provided with a rectangular groove and a support column is provided. The front legs of the seat are connected with the rear legs of the seat through hinges. The support ring is fixedly installed on the back leg of the seat; the seat cushion part includes a cushion frame, a support block and an elastic rope, and the support block is fixedly installed on the seat cushion frame and forms a rotational connection with the support ring. Elastic ropes are evenly distributed on the seat cushion frame; the backboard is fixedly connected with the telescopic bracket; the eccentric hexagonal cam is installed in the back leg of the seat and connected with the back leg of the seat through a hinge.

Preferably, the telescopic bracket can expand and contract for a certain distance within the main backrest bracket.

Preferably, the seat cushion frame is a mechanism that can be retracted from inside to outside.

Preferably, the backboard is a mechanism that can be retracted from inside to outside.

The outstanding advantages of the present invention are as follows:

<1> The present invention changes the position height of the backboard by changing the position of the telescopic bracket on the main backrest bracket.

<2> The present invention changes the seat width through the retractability of the cushion frame and the back board.

<3> The present invention can change the position height of the seat and the front and rear inclination of the backrest board by changing the angular position of the eccentric hexagonal cam and the main backrest bracket.

<4> The present invention shrinks the telescopic bracket to the main backrest bracket, and rotates the main backrest bracket to a position close to the rear legs of the seat, and then rotates the front legs of the seat to the inside of the rear legs of the seat to fold the seat for storage .
