Description

Integrated table and chair with front chair and rear table

Technical Field

The invention relates to a front chair and rear table integrated table and chair.

Background

Students often need to have a lunch break at school to ensure that they have sufficient energy to learn in the afternoon. The traditional mode is that noon break directly lies prone on the desk, then lie prone on the desk and can influence noon break quality. Therefore, the folding lunch break bed arranged on the wall of the classroom is invented by someone, the folding lunch break bed mainly comprises a vertical cabinet, a plurality of folding bed boards are arranged in the vertical cabinet, when the folding bed boards are not used, the folding bed boards are folded into each other and then are put into the vertical cabinet, when the folding bed boards are used, the folding bed boards are pulled out and unfolded outwards to be in a flat state, the vertical cabinet occupies the inner space of the classroom, and the lunch break demand of all students cannot be met. Therefore, people invent a simple lunch break bed formed by deforming the structure of desk and chair, but the existing desk and chair are in split structure, the combination of desk and chair is only arranged in parallel, the desk and chair are not connected, or the connection reliability is poor, students are easy to fall down when sleeping on the desk, the safety is poor, in addition, the desk and chair cannot reach the same plane (usually, the desk top is rotated and inclined downwards) even if the desk and chair are deformed and combined, and the comfort of the students is poor.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides the integrated table and chair of the front chair and the rear table, wherein the chair is arranged in front, the desk is arranged in rear, the front chair and the rear table are connected into a whole, the heights of the chair seat plate and the desk plate and the inclination of the backrest plate are adjusted, so that the integrated table and chair of the front chair and the rear table are convenient for students to have a lunch break, are safe and reliable, are comfortable for the students to sleep, and reasonably utilize the space in a classroom.

The technical scheme of the integrated table and chair of the front chair and the rear table is as follows: the chair comprises a bottom leg shared by a table and a chair, wherein the front side of the bottom leg is provided with a chair leg, the back side of the bottom leg is provided with a table leg, at least one table leg or chair leg can be adjusted in a lifting way, the chair leg is provided with a chair seat plate, the table leg is provided with a table plate, and the back side of the chair seat plate is connected with a backrest plate with an adjustable angle.

The invention discloses a front chair and back table integrated table and chair, which can form a rest bed after being inclined together with a backrest plate when the height of at least one of a table plate and a chair plate is adjusted to be basically coplanar (the table plate and the chair plate used by the same person are adjusted to be basically coplanar). The chair and chair rest bed keeps the manufacturing and using effects of the original chair and table, and the chair positioned in the front and the table positioned behind are connected into a whole through the bottom feet to form a desk and chair of a front chair and a back table. When the desk and chair are used, the desk plate with the desk and chair placed in front is adjusted to the normal use height, the chair seat plate with the desk and chair placed behind is adjusted to the normal chair height, and the backrest plate is adjusted to be in a vertical or slightly backward inclined state; when the multifunctional chair is used as a rest bed, two using methods are provided, one method is that a table and a chair are independently used as the rest bed, a human body sits on the chair seat plate, the backrest plate is inclined backwards, the waist back part leans against the backrest plate, and then the multifunctional chair can be used as the rest bed; the other is that two tables and chairs are combined to be used as a rest bed, and the specific operation method comprises the following steps: the desk plate of the front desk and chair (referring to the front where the human body is located) is descended, or the chair seat plate of the back desk and chair (referring to the back where the human body is located) is ascended, or the desk plate of the front desk and chair is descended and the chair seat plate of the back desk and chair are ascended simultaneously, so that the desk plate and the chair seat plate are close to or almost coplanar, the basic coplanarity refers to the fact that the desk plate and the chair seat plate are on the same plane or the desk plate is slightly higher than the chair seat plate or the chair seat plate is slightly higher than the desk plate, when the human body lies on the back, the transition of the hip and the waist back part in a flat lying or equal height cambered surface is more comfortable, the influence of the leg and the hip is slightly higher or slightly lower, so that the height difference between the desk plate of the leg placing foot and the chair seat plate of the hip placing can be slightly higher, the basic coplanarity can be achieved, then the back rest bed is formed by inclining backwards or flatly placing the back plate, the hip of the human body sits on the chair seat plate of the back desk and chair, the back and the head of the waist lean against the backrest plate in the inclined state, the front and the back can be combined for use, the two feet extend onto the table plate after the front desk and the chair descend, a space for placing the feet is formed between the backrest plate in the inclined state of the front desk and the table plate, the two feet can extend into the space, the back and the head of the front person can be used in a three-dimensional mode when the two feet are placed down, the space of a classroom is fully utilized, the contradiction between the occupation of a classroom field and a noon break bed is solved, the movement is not needed, or the distance between the front desk and the back chair can be slightly adjusted forwards and backwards, and the dual-purpose purposes of the chair table and the rest bed can be achieved only by adjusting the height of the desk and the inclination of the backrest plate. When the human body lies on the backrest plate, downward acting force (gravity) is downward acting force, the downward acting force is backward inclining force, the whole table and chair can be inclined backwards to stop inclining, the technical scheme moves the bottom feet backwards, the backrest plate is in an upper and lower symmetrical state with the positions of the bottom feet when inclined, the bottom feet are enabled to increase the supporting force for backward inclining of the table and chair, the supporting force and the backward inclining force are mutually confronted to obtain balance, the use of the table and chair is enabled to be stable and safe, meanwhile, the chair is suitable for being arranged at the rear head of the chair, the backward moving bottom feet are reasonably utilized, the front and rear length of the table and chair is not enabled to be too large, and the placing in a classroom is facilitated. The combination of the front chair and the rear desk is integrated, so that the problem that the student chair and the desk are inconvenient for noon break is thoroughly solved, the use safety problem existing when the combination of the student chair and the desk is converted into a rest bed is thoroughly solved, the combination innovation of facilities for student study and rest at a school is realized, the design thought of the traditional desk and the chair is broken, the structure of the existing desk and the chair is changed, the desk and the chair generate new functions and effects, the problem that the classroom configuration student noon break bed is urgently needed to be solved by the current education department is also solved, and a reasonable and practical noon break bed combining the desk and the chair is provided for a school.
