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.

The support members 26, 26 are fixed to each other by means such as welding.

Reference numeral 38 shown in FIG. 5 is a resin breaker that covers the upper surface of the front wall 4 of the insulation box, and includes an inclined part 39 for inclining the front plate 22 and a stop for positioning the lower end of the front plate. 40. 4
1 is a decorative frame that covers this breaker, and 42 is a dew-proof heater provided at the lower end of the front plate. Reference numeral 43 shown in FIG. 6 is a resin breaker that covers the upper surfaces of the left and right side walls 6, 6 of the insulation box,
A vertical portion 44 for vertically supporting 4 is formed. Reference numeral 45 denotes a fastening plate that locks a decorative frame 46 that holds the side plates 24, 24 inward, and applies a holding force to the decorative frame.

Next, the assembly of the transparent structure 3 will be explained.

The lower portions 26C of the support members 26, 26, whose upper and lower corner portions are interconnected by the upper and lower rails 35, 36, are fixed to the side walls 6, 6 by fasteners 47 such as screws, as shown in FIG. It is fixed to the upper part of the rear end and allows the upper part 26A to be slightly swingable in each of the up, down, left and right directions. Next, the front plate 22 and both side plates 24, 2

According to such an assembly method, both support members 26, 2
6 is of a cantilever type and is fixed to the insulation box 2 so that the upper part 26A can be slightly swung in each direction up, down, left and right, so for example, after the front plate 22 is fixed and suspended However, by swinging the upper portion 26A in the left and right direction, the top plate 23 and the side plates 24, 24 can be fixedly attached. Since the lower parts of the front plate 22 and the side plates 24, 24, which are suspended by slightly descending, come into contact with the breakers 38, 43, the strength of the transparent structure 3 can be increased, and the front plate 2
2. Since the top plate 23 and both side plates 24, 24 are fixed from the outside of both support members 26, 26, not only is the assembly work quick and easy, but also it is easy to replace each plate. It also makes the replacement work easier.
In addition, since the upper and lower corners of both support members 26, 26 are connected to each other by upper and lower rails 35, 36, the strength of both support members 26, 26 can be increased, and the range of swing during assembly can be restricted. can be achieved.

(e) Effects The cantilever support member whose upper part can swing slightly in left, right, up, and down directions not only makes it possible to quickly and easily assemble the front plate, top plate, and both side plates, but also allows the top plate to be easily assembled. Since the load of the front plate and both side plates is applied to the cantilever support member, there is no gap between the support member and the insulation box, which improves the sealing effect. The plates are restricted from moving outward and function as reinforcing members, and the strength of the see-through structure can therefore be increased as the plates are assembled.
