Abstract

PURPOSE:To reduce a packing cost and transporting cost by injecting fluid into a circumferential edge at the time of use to expand this circumferential edge to a pre scribed size and reducing the volume of the circumferential edge before injection of the fluid. CONSTITUTION:The entire part of the circumferential edge 2 of a rectangular annular shape existing around a holding part 1 has a fluid injecting part 3. A bag-shaped body 2 is expanded and held to the prescribed circumferential edge shape by the air injected from the injecting part 3. Respective frame bodies 8A are elastically fitted to the circumferential edge of a laminated glass plate 6, elastic mat 5, work P and rear plate 7 and thereafter, this holding frame 8 is fitted into a recessed part 1 formed in the continuous state to a rectangular shape between the front surface of a flexible sheet 4 and the outer peripheral surface of the bag-shaped body 2. The holding frame 8 is then elastically clamped and held by utilizing the elastic deformation of the bag-shaped body 2. To store the picture frame, a user removes a cap 3b of the injecting part 3 and discharges the air in the bag body 2 outside from the injection port of the air injection plug 3a. The entire part of the bag-shaped body of the circumferential edge is then flattened and since the bag-shaped body 2 is soft, the bag-shaped body is foldable to an arbitrary shape.

In this type of picture frame, since the decoration function in addition to the exhibition and storage function of the work P is extremely important, the work P is aimed at the profound feeling of the picture frame and the sense of quality. The peripheral edge located along the periphery of the storage part of the vehicle tends to be large and thick. However, in the conventional frame, the peripheral frame itself is assembled into a rectangular shape with a hard material such as wood, so that the larger the peripheral frame and the thicker the frame, the bulkier the frame is. There was a problem that led to soaring prices.

A main object of the present invention is to make it possible to reduce the packaging cost and the transportation cost while the peripheral edge is formed to have a predetermined size when used as a frame. In addition, as other purposes, promotion of reduction of packing cost and transportation cost, improvement of design effect on the outer appearance of the peripheral edge, simplification of a stopper structure that prevents the work attached to the peripheral edge from moving out, Ensuring the effect of preventing the work attached to the periphery from slipping out, facilitating production,
It is possible to enumerate points that aim to simplify the work of attaching and detaching works.
