Description

Chair with detachable top

Technical Field

The utility model relates to the field of furniture, in particular to a chair.

Background

Most of chairs in the market occupy large space after being disassembled, and are not easy to package and transport, firstly, because a back support of a chair back connected with a chair seat or a chassis is wide and bent, the occupied space is difficult to control during packaging; secondly, because the single chair back is severely limited, if the chair back is designed to be higher, the area of a user which can be attached to the chair back is large, the comfort is good, but the size of the chair back is large, the occupied space is large during transportation, and the chair back is relatively wasted; if the chair back is designed to be short, the size of the chair back is small, the transportation is convenient, but the use comfort is reduced to some extent.

The patent of the utility model discloses an improvement of a combination structure of a chair back plate and a seat cushion chassis in TW090210575, which is characterized in that an extension section for being provided with the seat cushion chassis is arranged on a transverse rod section of a U-shaped pipe frame, a combination seat is spliced at the upper ends of two side straight rod sections of the U-shaped pipe frame, and a plate sheet on the combination seat is locked at the back side end surface of the chair back plate after a screw fastener is penetrated; therefore, the back board of the chair back and the chassis of the seat cushion can be firmly combined and assembled, and the structural strength of the U-shaped pipe frame and the attractiveness of the whole chair are not damaged. The utility model has the main advantages that the connection between the U-shaped pipe frame and the back plate of the chair back can well protect the structural strength of the U-shaped pipe frame and the appearance beauty from being damaged; but also adopts a detachable connecting structure, so the chair is beneficial to transportation; however, due to the single back board of the chair back, the single back board of the chair back has single function and conflicts exist between the transportation and the better comfort: if the design of the back plate of the chair back is high, the transportation cost is also increased, and if the design of the back plate of the chair back is low, the whole use comfort of the chair is influenced.
