Problems solved by technology

[0012] However, in the tensioned laying structure of the tensioned laying member for chairs, since the fitting member is fitted into the notch of the frame and fixed to the notch with screws, the screw fixing work is complicated, and the When the tension laying member is separated from the frame and the chair is discarded, the screws must also be removed, which is a cumbersome operation.

Embodiment Construction

[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0046] Figure 1 to Figure 9 A first embodiment in which the present invention is applied to a backrest of a chair is shown. figure 1 It is a front view of a chair having the first embodiment of the present invention, figure 2 is a side view of the chair.

[0047] The chair 1 includes a backrest 10 , a seat 11 , and a leg frame 12 for supporting the backrest 10 and the seat 11 . like image 3 As shown, the backrest 10 includes a closed loop frame body 13 and a tension laying member 14 stretched on the surface (front surface) 13 a of the frame body 13 .

[0048] The tension layup 14 is formed to be stretchable using a mesh material. The peripheral portion 14a of the tension paving member 14 is formed in a bag shape, and an elongated flat edge member 14b made of an elastic synthetic resin is inserted into the peripheral portion 14a (refer to Figure 7 ). Alternat...

Abstract

An engagement protrusion (20) extending in the front / back direction of a frame body (13) is provided on one of the opposing surfaces of a notch (16) in the frame body (13) and a fitting member (17) opposite said notch; similarly, an engagement recess (13h) in which the engagement protrusion (20) fits is provided on the other of said surfaces. By means of the moment of the fitting member (17) resulting from the tension of a tension member (14), the engagement protrusion (20) and the engagement recess (13h) are prevented from separating.

Description

technical field [0001] The invention relates to a tension laying structure of a tension laying member for a chair. Background technique [0002] In recent years, among office chairs used in office spaces or meeting rooms, etc., it is common to support the backrest of the seated person with a backrest that is stretched with an elastic surface material, that is, a tensioned laying member. Use a chair. Usually, the front surface of the back frame (frame body) which is formed into a closed loop using easy-to-form metal such as aluminum or synthetic resin to cover the backrest of such a chair with a tension laying member is fixed to the peripheral portion of the tension laying member. The rear surface or the side of the back frame, so that the tension laying member is tensioned and laid on the back frame (for example, refer to Patent Document 1). [0003] On the other hand, there is also a strong demand for a so-called cantilever-type chair in which a backrest is connected to a...
