Description

multifunctional seat

technical field

The invention relates to a multifunctional seat, in particular to a multifunctional seat integrating a chair, a wheelchair, a table, a shopping cart, a trolley and a bed.

Background technique

The existing seats have simple functions and can only be simply folded and folded so as to reduce the occupied area, have few functions, and can only meet indoor daily use, and have a single function.

For this reason, some multifunctional seats have occurred in the prior art, such as Chinese utility model patent, the patent No. is " zl03244471.0 ", and the name is called " multifunctional chair ". Its abstract and technical features are: a multifunctional chair, which can be used as a chair; it can also be used as a single bed when it is opened; a board can be installed on the two armrests, and you can sit on the chair and eat, which is very convenient and suitable. Hospital patients and staff accompanying patients. The structure of the multifunctional chair is mainly made of iron frames. Although it is divided into several parts, each part has a shaft connection, which can be combined and opened. It is combined with an iron frame. This structure is very strong and firm. Installed on an iron shelf. When it is opened, each part is laid flat, and the iron frame and armrests are the support of the bed board, and several wooden boards are opened one by one to form a single bed. When retracting, fold back a few boards, insert the fixing pins, and it becomes a chair. The iron frame is not only the support of the bed, but also the main support of the chair, but when it is opened, it can realize different functions. The combination of the shaft and the board of each part is ingenious, so that after the chair is opened, it can maintain a flat surface, and the board surface will not be uneven due to the existence of the shaft; when it is closed, the board surface will not be caused by the shaft. and cannot be closed. The seat plank of the chair has two layers. When it is a chair, the two layers are combined; when it is used as a bed, the two layers of planks are opened, which are the panels of the bed, and then the backrest is put down (the backrest can also be folded. ), which is a single bed.

The multifunctional seat provided by this patented technology has two functions, which solves the problem of single function of the seat to a certain extent, but it is not convenient enough to use, and the wooden board needs to be disassembled, and its functions are still relatively few and cannot be used. Meet the application of various situations in daily life.

Contents of the invention

The present invention aims to provide a multifunctional seat, a multifunctional seat integrating a chair, a wheelchair, a table, a shopping cart, a trolley and a bed, which can also be folded and stored for easy transportation, and meets the requirements of people's daily life. needs.

To achieve the above object, the technical solution of the present invention is: the multifunctional seat comprises a main backrest frame, an auxiliary backrest frame, a rear support leg, an armrest, a rear foot, a front foot, a rear foot link, a front foot link and a seat frame; The middle part of the backrest frame is provided with a card slot; the rear legs and the lower ends of the front feet are respectively equipped with rear wheels and front wheels; The lower end is connected with the upper end of the rear foot link through the rotating pair B; the lower end of the rear supporting leg is connected with the lower end of the auxiliary backrest frame through the rotating pair C; The swivel pair D connected to the seat frame; the armrest is L-shaped, one end is stuck in the middle of the main backrest frame through a card slot, and the other end is connected to the upper end of the rear foot through the swivel pair J; the middle part of the rear feet is respectively passed through the swivel pair E The upper end of the front foot link and the lower end of the rear foot link are connected with the rotating pair F; the upper end of the front foot is connected with the right end of the seat frame through the rotating pair H, and the middle part of the front foot is connected with the other end of the front foot connecting rod through the rotating pair G ; The end connecting the seat frame with the front foot is provided with an armrest holder.

The effect of above-mentioned technical scheme is:

1. When the vehicle frame is in the seat state, the free end of the armrest is stuck in the groove of the main backrest frame; Pull it out, rotate the armrest around the rotation joint J to a horizontal state and lean on the armrest holder of the seat frame, rotate the main backrest around the rotation joint B to the horizontal direction, and rotate the auxiliary backrest around the rotation joint A to Horizontally, at the same time, the rear support leg rotates around the rotating pair C until it can support the ground, so that the frame has a seat and can be transformed into a bed;
