Description

A collapsible table and chair

technical field

The invention relates to a desk and chair, in particular to a flat foldable desk and chair.

Background technique

  At present, more and more students are being advocated for all-round development, and students urgently need a venue where they can move freely. Various associations and student organizations in colleges and universities often need to hold various activities, but there is usually a lack of venues for holding activities on campus; the space that can be freely arranged in ordinary classrooms is small, which limits the scale of activities. In order to overcome the shortcomings of traditional classrooms, we designed "flatable tables and chairs" to easily transform ordinary classrooms into active classrooms, so that students can carry out various activities without going out of the classroom, and at the same time solve the limitations of the preset tables and chairs for exhibitions, Disadvantages of capacity for events such as job fairs.

The classroom teaching process often involves group activities. The fixed-mode classroom is not convenient for group members to get together to exchange ideas, and it is difficult to cultivate students' teamwork awareness and ability. The exam requires a single table for one person, separated in the middle. When arranging the exam room, most schools put unnecessary desks behind or outside the classroom, which is extremely labor-intensive and time-consuming. Although the entire row of fixed seats in universities You can sit apart, but it is not convenient for invigilation, and cheating is very serious.

In order to enrich students' after-school life, schools usually have a small number of special activity rooms. When there are no activities, the activity classrooms are idle for a long time, and when there are many activities, such classrooms are often not enough. It is obviously not worth building more activity classrooms, and during the peak period of activities, the number of activity approvals and activity time will be reduced due to too few activity classrooms. As a result, the quality of activities will be greatly reduced and the expected goals will not be achieved. In view of the above status quo, we decided to start with the classroom tables and chairs, and through structural transformation, the classroom tables and chairs can be seamlessly laid on the ground, and the transformation from ordinary classrooms to multi-functional classrooms can be easily realized.

Contents of the invention

The present invention aims to provide a foldable desk and chair that can be flattened. With just a slight push, the desks and chairs can be upright or laid flat, allowing students to carry out various activities without leaving the classroom and effectively utilizing the space.

To achieve the above object, the present invention adopts the following technical solutions:

A flat foldable table and chair, at least including a table and chair base, a bearing, a first connecting rod, a second connecting rod, a first supporting surface, a second supporting surface, a third connecting rod, a stool surface and a supporting rod; The first connecting rod and the second connecting rod are rotationally connected to the base of the table and chair through a bearing arranged at the right end of the base of the table and chair; the bottom end of the third connecting rod is connected to the first support surface, the top end and the bottom end of the right end of the second support surface connection; the right end of the first support surface is rotatably connected to the top of the second connecting rod; the support rod is rotatably connected to the base of the table and chair; the stool surface is arranged on the top of the support rod and is rotatably connected to the support rod.

The base of the table and chair, the bearing, the first connecting rod, the second connecting rod, the first supporting surface, the second supporting surface and the third connecting rod constitute a six-bar linkage; the stool surface, the supporting rod and the base of the table and chair constitute Parallel four-bar mechanism.

Compared with prior art, the beneficial effect of the present invention is:

(1) Realize the concept of multi-functional classrooms, combining ordinary classrooms and activity-specific classrooms into one, increasing the utilization rate of classrooms and enriching students' campus life.

(2) The six-bar linkage mechanism, parallel four-bar mechanism, and the dead point support mechanism derived from the aircraft landing gear and the spring mechanism derived from the bicycle bracket are fully reflected in this design.

(3) It is easy to operate, and the table and chair can reach the state of upright or flat and will be locked automatically with a single push by a single person.

It can be used in colleges and primary and secondary schools. At present, the comprehensive development of primary and secondary school students is increasingly advocated. Students urgently need a place where they can move freely. This design just allows students to carry out various activities without leaving the classroom. In universities, various associations and student organizations often need to hold various activities, but there is usually a lack of venues for activities on campus, and the space of ordinary classrooms is small, which limits the scale of activities. According to this design, ordinary classrooms can be easily transformed into activity classrooms ; For activities such as exhibitions and job fairs, the preset tables and chairs in the classroom will limit the number of people that the venue can accommodate, and this design can also solve the problem; the overall structure is simple, practical, easy to manufacture, and easy to promote and use.
