Description

Technical Field

[0001] The present invention relates to the technical field of chairs, and in particular to an assembled chair. Background Art

[0002] Chairs are indispensable items in life and are widely present in our daily environment.

[0003] Most chairs currently on the market use screws to connect various parts, or are directly fixed together. This method not only makes the assembly and disassembly process of the chair cumbersome, but also affects the overall appearance of the chair, especially when the screws rust, which reduces the aesthetics of the chair. In addition, some existing chairs are injection-molded in one piece, which makes them impossible to disassemble during transportation, thereby taking up a large space and increasing transportation costs. At the same time, the one-piece injection-molded chairs are easily damaged during transportation, which increases transportation losses.

[0004] For example, Chinese patent CN201320824755.4 discloses a chair in which various components are fixed together by screws, which makes disassembly and assembly cumbersome and affects the overall appearance.

[0005] Another example is an injection-molded assembled chair disclosed in Chinese patent CN202120906624.5, which also uses fasteners such as screws or bolts to fix the various components together.

A six-way card slot 111 is recessed rearwardly at the bottom of the rear side wall of the opening 11. The upper end of the side panel 1 has an armrest portion 10. A first card slot 12 is recessed downwardly on the rear side of the upper end surface of the side panel 1, that is, the rear portion of the armrest portion 10 is recessed with the first card slot 12. A eighth card slot 15 is formed in the middle portion of the front side of the side panel 1. The upper edge of the eighth card slot 15 is lower than the lower edge of the opening 11. A second card slot 13 is formed on the rear side of the side panel 1. A eleven-way card slot 16 is formed on the rear side wall of the lower half of the side panel 1.

[0051] A fourth retaining groove 22 is recessed forward on both sides of the rear end surface of the seat plate 2. The width of the fourth retaining groove 22 matches the thickness of the side plate 1. A third retaining groove 21 is recessed backward on both left and right sides of the front end surface of the seat plate 2. The third retaining groove 21 matches the thickness of the side plate 1. A protrusion 24 extends forward from the front end surface of the seat plate 2 between the two third retaining grooves 21.

[0052] The left and right sides of the lower half of the backrest 3 are both inwardly recessed with an avoidance groove 33, the upper side wall of the avoidance groove 33 is recessed upward to form a clamping groove 5 31, and the lower side wall of the avoidance groove 33 is protruding to form a plug-in portion 1 32;

[0053] A support portion 42 protrudes upward from the middle of the front crossbeam 1 4, and a clamping groove 7 41 is recessed upward from the lower sides of the left and right ends of the front crossbeam 1 4;

[0054] The left and right ends of the rear cross beam 5 are both provided with a second plug-in portion 51, and the second plug-in portion 51 is provided with a slot 9 52;

[0055] After assembly, the side end of the seat plate 2 is placed in the opening 11, the slot four 22 is engaged with the slot six 111, the slot three 21 is engaged with the bottom of the front side wall of the opening 11, the rear side of the side plate 1 is placed in the avoidance groove 33, and the slot five 31 is engaged with the slot one 12, the plug-in portion 1 32 is embedded in the slot two 13, the support portion 42 abuts against the lower end of the protrusion 24, the slot seven 41 is engaged with the lower side wall of the slot eight 15, the plug-in portion 2 51 is inserted into the slot eleven 16, and the slot nine 52 is engaged with the slot eleven 16 and is tightly connected.

[0056] First, insert the side end of the seat plate 2 into the opening 11, and then make the fourth slot 22 and the sixth slot 111 fit together and tightly connected. Then, rotate the front end of the seat plate 2 with the sixth slot 111 as the center of the circle, so that the third slot 21 is fit together and tightly connected with the bottom of the front side wall of the opening 11, and the inner walls of the fourth slot 22 and the third slot 21 on the outer side are both in contact with the side end of the side plate 1, thereby improving the force-bearing capacity of the middle part of the seat plate 2.

[0057] When the side panel 1 and the backrest 3 are installed, the upper half of the side panel 1 can be placed in the avoidance groove 33, and the upper side wall of the avoidance groove 33 is placed on the upper end surface of the side panel 1, thereby realizing the interlocking connection between the card slot 5 31 and the card slot 1 12.

[0058] The end of the front cross beam 4 is first inserted into the slot 8 15, and then the front cross beam 4 moves downward so that the slot 7 41 is embedded in the lower side wall of the slot 8 15 and is tightly connected. When the seat plate 2 is installed on the side plate 1, the support portion 42 abuts against the lower end of the protrusion 24 to support the front end of the seat plate 2 to prevent the seat plate 2 from being bent and deformed due to excessive force.

[0059] The side panel 1 located on the rear side wall of the opening 11 is tilted. When the backrest 3 is installed on the side panel 1, the side wall of the backrest 3 is flush with the rear side of the upper half of the side panel 1, so that the backrest 3 is tilted after installation, which is convenient for fitting with the person's back and improving the comfort of use.
