Description

A flat table and chair

technical field

The utility model relates to a piece of furniture, in particular to a flat table and chair.

Background technique

At present, universities, middle schools and primary schools all advocate the all-round development of students. Various activities are an effective way to enrich students' after-school life. However, building new activity classrooms and activity buildings will cost a lot of money, and the utilization rate is not high, and most of the time they are idle. According to the requirements of building a conservation-oriented society, making full use of limited classroom resources, the multi-functionalization of classrooms is the best solution. Most of the desks and chairs in school classrooms can be divided into fixed and non-fixed. Among them, the fixed desks and chairs common in universities limit the function of the classroom, so that they can only meet the needs of general classroom use; the non-fixed desks and chairs common in primary and secondary classrooms are not easy to move because of the inconvenience. The purpose of "one room for multiple purposes". Therefore, designing a flat table and chair to solve the multifunctional problem of the classroom is a technical problem to be solved at present.

Invention content

The technical problem to be solved by the utility model is to provide a table and chair that can be tiled to solve the multifunctional problem of the classroom.

The technical scheme that the utility model solves its technical problem is:

A table and chair that can be flattened, including a table and a chair. The table is composed of a table top, a table base, table legs A and table legs B. An angle steel A is fixed on the lower part of the table top, and the upper end of the table leg A is hinged on the The front end of angle steel A is fixed with angle steel B on the upper part of the bottom plate of the table, a connecting rod is hinged at the rear end of angle steel A, the other end of the connecting rod is hinged at the rear end of angle steel B, and the lower end of table leg A is hinged on the On the base plate, the upper end of the table leg B is hinged to the front end of the angle steel B, and the lower end of the table leg B is hinged to the base plate through the table foot base B, and a table self-locking device is provided between the middle part of the table leg A and the base plate. It constitutes a planar six-link mechanism; the chair is composed of a chair surface and chair legs. There is a chair self-locking device, and each chair is constructed to form a parallel four-bar linkage mechanism. When the table is upright, the table top and the table bottom are parallel, and when the table is laid flat, the table top and the table bottom are combined into a plane; the chair is folded between the two table boards and the ground to play a supporting role.

Of course, the table self-locking device and the chair self-locking device can be detachable, but as a preferred solution of the utility model, the table self-locking device and the chair self-locking device are all plates with L-shaped slotted holes , the lower ends of the self-locking device of the table and the self-locking device of the chair are hinged with the bottom plate, there are T-shaped trunnions in the middle of the table leg A and the chair leg, and the table self-locking device is slidingly connected with the T-shaped trunnion on the table leg A , the chair self-locking device is slidingly connected with the T-shaped trunnion on the chair leg, when the T-shaped trunnion on the table leg A is at the turning end of the L-shaped long slot hole of the table self-locking device, the table is upright and self-locking, when When the T-shaped trunnion on the table leg A is at the straight end of the L-shaped long slot hole of the self-locking device of the table, the table is folded flat; When the turning end of the slot hole is turned, the chair is upright and self-locking; when the T-shaped trunnion on the chair leg is at the straight end of the L-shaped long slot hole of the chair self-locking device, the chair is folded flat.

As a preferred solution of the present utility model, shaft supports are arranged on the upper ends of the table legs A, table legs B, and chair legs, and the table top, table base and chair surface are all connected by respective shafts and respective shaft supports. They are respectively hinged with table leg A, table leg B and chair leg.

Compared with the prior art, since the table is composed of a group of six linkages, the chair is composed of a parallel four-bar mechanism. During normal classroom use, the desk and chair are in an upright position. When used for other purposes such as after-school activities, the tables and chairs are in a flat state. The utility model includes a set of self-locking device, relying on the self-locking device can ensure the stability when it is upright, and the self-locking device is easy to operate, and one person can realize the conversion of the state of the table and chair. The shapes and sizes of the table top, table legs and chairs of the utility model have been rigorously calculated and designed, which can ensure that the front and rear tables and chairs are connected end to end after being tiled, and the seams are as tight as tiles. When the utility model is in the flat state, the table legs are directly supported by the ground, and the chair is folded between the table top and the ground, so as to ensure that each position on the table surface can obtain sufficient support and ensure the safety of personnel activities.
