Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field The present invention relates to a method for assembling a transparent structure disposed to cover the top opening of a heat insulating box so that the interior of a cold storage case or the like can be seen through.

(b) Background technology and its problems When conducting face-to-face sales with a customer standing at the front of a low-temperature store case and a store clerk standing at the back, it is necessary to open the top of the heat-insulating box so that both sides can clearly see the products inside. A covering transparent structure is disposed. This low-temperature show case equipped with a see-through structure was developed in 1983.
This is shown in Publication No. 64374. In such a transparent structure, opaque left and right side plates each having an arcuate guide rail formed on the inner wall are fixed to the left and right side walls of the insulation box so as to face each other, and the upper ends of the front and rear walls of the insulation box are fixed. A heat-insulating decorative frame is installed on each side, and then both ends of the reinforcing member, which is in contact with the upper inner surface of the front glass plate and the front inner surface of the upper glass plate, respectively, and the reflecting plate, which also serves as a reinforcing member, which is in contact with the rear inner surface of the upper glass plate, are attached on both sides, respectively. After fixing the front glass plate and the top glass plate to the reinforcing member and the reflecting plate, respectively, attach the sash to the upper part of the reinforcing member and the upper part of the reflecting plate. It is assembled by overlapping the rear panels and finally placing the transparent door on both rails.

According to such an assembly method, both side plates are attached to the insulation box first, so even if the dimensional accuracy of the reinforcing member, reflective plate, and both front and top glass plates is high, the attachment work must be done on both sides. This has to be done from the inside of the panel, making the assembly work extremely complicated.Also, when replacing both the front and top glass panels, the sash and rear panel must be removed, making the replacement work complicated. Summer.

(c) An object of the present invention is to quickly and easily assemble a see-through structure.
