Elastic insertion type chair plate bar chair

Abstract

A bar chair with an elastic spliced seat board comprises a pedestal, lifting legs arranged on the pedestal, and a seat board arranged on the legs and respectively connected with a tray connected with the legs and a seat panel on the tray. The bar chair is characterized in that folded edges are formed at the periphery of the seat panel of an elastic body; a cavity is formed in the folded edges; a connection board is arranged on the entire bottom surface of the seat panel of the elastic body in such a manner that the periphery of the connection board is arranged in the cavity; supporting and positioning sheets and hooks are formed below the connection board; ribs and fixed grids among the ribs are formed on the tray; slots are formed on the ribs; the supporting and positioning sheets of the connection board match the fixed grids in the tray; and the hooks match the slots. During the installation, the supporting and positioning sheets are arranged in the fixed grids for positioning and supporting, and the hooks are inserted into the slots to fix the connection board and the tray, thus achieving convenient entire assembly and connection, good matching, and reliable and firm effect.

Description

technical field [0001] The invention relates to a chair, in particular to an elastic plug-in seat panel bar chair, which belongs to the field of furniture. Background technique [0002] In bars, banks, and before the windows of relevant ticket offices (such as civil aviation ticket offices, etc.), high bar chairs with high and low lifts are generally used. The basic structure of this type of chair is to install the lifting chair feet of height and height on the metal base, and the seat plate is installed on the lifting chair feet. The structure of the seat plate is various and many, but the basic seat plate The structure is divided into a tray and a seat, and the tray and the seat are connected by fasteners, so its disadvantages are: first, the installation of the fastener connection is troublesome, and the fastening such as screws is easy to loosen; the second is that the tray and the seat After the board is fastened, the elasticity is poor, and the human body is uncomfort...

AI Technical Summary

Problems solved by technology

The basic structure of this type of chair is to install the lifting chair feet of height and height on the metal base, and the seat plate is installed on the lifting chair feet. The structure of the seat plate is various and many, but the basic seat plate The structure is divided into a tray and a seat, and the tray and the seat are connected by fasteners, so its disadvantages are: first, the installation of the fastener connection is troublesome, and the fastening such as screws is easy to loosen; the second is that the tray and the seat After the board is fastened, the elasticity is poor, and the human body is uncomfortable to sit on

For this reason, someone has designed a kind of upper seat surface (being seat board) and lower seat surface (being tray) with fixture fixing, and without fastener, simplified structure, as No. ZL200520066035.1 of Chinese patent, but this technology The upper seat surface (seat plate) of the scheme is directly installed on the lower seat surface (tray), and the fixing member is a ring, especially the inner cavity of the lower seat surface is provided with criss-cross ribs. If the upper seat surface is an elastic body ( Soft) contact with the ribs will inevitably affect the service life, if the upper seat surface is rigid, the hardware has poor elasticity

On the other hand, the clips on the bottom surface of the ring-shaped fixing part and the clips around the lower seat surface are both on the edge of the seat plate, and the force of the matching connection is unreasonable.

On the other hand, the upper seat surface completely depends on the ring-shaped fixing part to press and buckle the edge on the lower seat surface, and the upper seat itself has no effective connection with the fixing part and the lower seat surface. When the human body sits on the upper seat surface, the upper seat surface is pressed outward. Expansion, when the human body leaves the upper seating surface, the upper seating surface rebounds and shrinks inwardly, and after repeated friction on the edge, gaps are formed, which are easy to damage
