Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field The present invention relates to a seal structure for a see-through structure used in a show case or the like.

(B) Background Art In FIG. 7, 22 is a transparent front plate, 24 is a side plate that is perpendicular to the front plate with a gap 61 therebetween, and 70 is a soft sealing member made of a heat insulating material. This sealing member includes a clamping part 70A whose inner surface contacts a part of both the inner and outer surfaces and the side surface of the front plate 22, and a fin piece that extends outward from both sides of the clamping part and is pressed and deformed by contacting the inner surface of the side plate 24. It consists of leg portions 70B and 70B provided with 70C and 70C, respectively. A space 71 is formed between the side plate 24 and the seal member 70 when the seal member 70 is attached.

The sealing member is first attached to the front plate 22 and then pressed and deformed by the side plates 24 fixed perpendicularly to the front plate 22.

According to such a seal structure, the front plate 22 and the side plate 2
4 is limited, and even when replacing the front plate 22, the side plate 24 must be removed first, and the side plate 24 must be removed first.
When the fin piece 70C is fixed, the fin piece 70C is deformed in the opposite direction as shown by the chain line A in FIG.

(c) Object of the present invention It is an object of the present invention to perform the sealing work quickly and easily, and to increase the pressing force of the locking portion to prevent the generation of a gap between the locking portion and the front plate.

The main body is constituted by a transparent structure 3 arranged to cover the opening. The insulation box has a front wall 4, a rear wall 5 having an upper part with a protrusion 7 projecting backward, a lower part with an opening 9 that is closed by an insulation door 8, and both left and right sides whose upper surfaces slope downward toward the front. walls 6, 6 and a recess 10 arranged in the upper part of said rear wall and together with a protrusion 7;
and a ceiling wall 11 made of a moisture-resistant heat insulating material that defines a wall, and a first cooler 12 made of a meandering cooling pipe arranged on the inner wall exchanges heat with cool air that naturally convects as shown by the chain arrow in Fig. 3. Accordingly, the partition plate 13
A plate-fin type second cooler 16 is arranged in the recess 10 located above the load line 15 and has a smaller amount of heat exchange than the first cooler. The upper space inside the refrigerator above the load line 15 is cooled by the cool air that undergoes heat exchange and naturally convects as shown by the solid arrow in FIG. 3. 17
1 is a dew pan placed directly below the second cooler 16;
8 is a defrosting device such as a defrosting heater placed in the second cooler 16, and 19 is a ventilated guard placed in front of the recess 10 together with the hanging wall 20. In addition, 2
Reference numeral 1 denotes a machine room in which a refrigerant compressor, a condenser, etc., which together with the first and second coolers constitute a refrigeration cycle, are installed.

The transparent structure includes a front plate 22, a top plate 23, left and right side plates 24, 24, each made of transparent glass, and two transparent doors 25, 25' of different sizes, which are sliding left and right and are mainly made of transparent glass. , as shown in FIG. 4, is composed of a pair of left and right support members 26, 26 that support these plates and the transparent door. This support member is made of a thin metal plate bent into a U-shape to form a groove 27.
A hole 3 opposite to the holes 28, 29, 30 formed at the upper ends of the side plates 24, 24 and at both ends of the top plate 23.
1, 32, and 33, and includes an upper portion 26A extending forward, an inclined portion 26B inclined backwardly from the rear end of this upper portion, and two holes 34 extending rearward from the lower end of this inclined portion. The lower part 2 formed
It consists of 6C. 35 and 36 are both support members 26,
26 and also serves as a reinforcing member to support and guide the transparent doors 25, 25' in the left and right direction. and inclined part 26B
The ends of the lower rail 36 are fitted into the grooves 27 located at the upper corners of the supporting members 26, 26, and the lower rails 36 are fitted into the grooves 27 located at the lower corners of the inclined portions 26B and lower portions 26C of the support members 26, 26, and are fitted into the grooves 27 located at the upper corners of the supporting members 26, 26, and are fitted into the grooves 27 located at the upper corners of the support members 26, 26, and are fitted into the grooves 27 located at the lower corners of the support members 26, 26. It is fixed to the supporting members 26, 26 by means of. 47 is a stopper for fixing both support members 26, 26 to the insulation box 2;
9,50 has a front plate 22 and a top plate 23 on the upper part 26A
and both male and female fasteners for fastening the side plates 24, 24;
51 is Watshiya.

Reference numeral 60 shown in FIG. 5 is a sealing member made of a transparent heat insulating material such as vinyl chloride, which closes the gap 61 between the front plate 22 and the side plates 24, 24, which are perpendicular to each other. This sealing member includes a hard insertion part 60A that is inserted into the gap 61 and whose inner surface abuts the side surface of the front plate 22, and a sixth part from one end of this insertion part.
A hard locking portion 6 extends so as to form an acute angle θ as shown in the figure, and whose inner surface abuts the outer surface of the front plate 22.
0B, and soft fin pieces 60C, 60C that extend diagonally outward from the outer surface of the insertion portion and whose tips abut against the inner surfaces of the side plates 24, 24 and are deformed by pressure. Reference numeral 62 denotes an arcuate space formed between the outer corner of the front plate 22 and the inner corner of the seal member 60 when the seal member 60 is inserted into the gap 61.

According to such a seal structure, the front plate 22 and the side plate 2
4 and 24, the sealing member 60 can be inserted into the gap 61, and the fin piece 60 can be inserted into the gap 61.
Since C and 60C themselves extend diagonally outward, the seal member 60 can be inserted smoothly, and once inserted, the seal member 60 is attached to the front plate 22.
Not only do they have a large contact area with the side plates 24, 24, but also the fin pieces 60C, 60C act as a stopper, so they will not come off from the gap 61 unless either the front plate 22 or the side plates 24, 24 are removed. In addition, the insertion portion 60A and the locking portion 60
By making an acute angle with B and forming a space 62 as the sealing member 60 is inserted, the space 6
2, the pressing force of the locking portion 60B is increased and the front plate 2
2 outer surface and the inner surface of the locking portion 60B can be prevented from forming a gap.

(E) Effect: After fixing the front plate and side plate, the gap between the two plates can be quickly and easily closed using a sealing member, and the space increases the pressing force of the locking part, improving the sealing effect. can.
