Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a windshield glass mounting structure in a frozen and refrigerated open showcase used for displaying refrigerated foods, fresh foods, and the like in food stores such as supermarkets and convenience stores, and more particularly to a structure for fixing a lower corner portion of a windshield glass.
[0002]
[Prior art]
As a windshield mounting structure in a conventional open showcase, for example, there is one described in Japanese Patent Laid-Open No. 8-219631. In this case, a notch hole is provided in an inner corner portion which becomes a windshield glass mounting surface in a trim of a side plate formed as an integral body, and the corner portion of the windshield glass is fitted and attached to the notch hole.
[0003]
[Problems to be solved by the invention]
However, the notch hole needs to be slightly larger than the corner of the windshield, so that the peripheral edge of the notch hole is exposed to the outside and the appearance is deteriorated. In addition, since the size of the cutout hole varies depending on the thickness of the windshield glass, there is a problem that a dedicated side plate must be manufactured for each thickness of the windshield glass.
[0004]
In view of the above-described problems, the present invention allows the windshield glass in an open showcase to be used in common only by exchanging the fixing device attached to the side plate when using the windshield glass having different thicknesses. The object is to provide a mounting structure.
[0005]
[Means for Solving the Problems]
According to the present invention, the above problem is solved as follows.
(1) In a windshield glass mounting structure in an open showcase in which a windshield glass is attached to a window hole formed in a side plate of the open showcase and having an opening at the front end, the lower corner of the rear side of the windshield glass is disposed at the front. Holding the glass holding part to the fixing tool, and inserting the protruding piece protruding from the rear part of the fixing tool into the notch hole drilled in the trim fixed to the edge of the window hole of the side plate, Attach the fixture to the side plate.
[0006]
(2) In the above paragraph (1), the windshield glass holding portion that is attached so that one side surface of the windshield glass is aligned with either the left or right side surface of the side plate and covers one side surface of the windshield glass in the fixture. And extending along the side surface of the side plate.
[0007]
(3) In the above item (1) or (2), a flange is formed at a contact portion between the windshield holding portion near the center of the trim and the windshield mounting surface of the trim in the fixture.
[0008]
(4) In any one of the above items (1) to (3), the rear lower corner portion of the trim windshield mounting surface is formed by butting the horizontal trim and the vertical trim.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a refrigerated showcase (A) as an example of an open showcase. The left and right side plates (1) have a window hole (1a) whose front end is open, and a windshield (2 ) Is attached. The present invention resides in the windshield (2) mounting structure.
[0010]
As shown in FIG. 2, the side plate (1) is mainly composed of an inner plate (3) and an outer plate (4) that are substantially U-shaped when viewed from the side, and has a channel shape with a shallow cross section at the periphery. The three split-type trims (5), (6), and (7) that form a part are fitted and fixed, and urethane resin is foam-filled into the internal space to form a heat insulating layer (8) (see FIG. 6). is there.
[0011]
The window hole (1a) of the side plate (1) has a shape in which the lower part extends almost horizontally from the front to the rear, extends upward from the lower corner of the rear, gradually turns forward, and the upper end returns to the front. The trim (6) and the trim (5) are abutted at a substantially right angle in the lower corner portion described above.
[0012]
A frame member (9) having a U-shaped cross section, which is a sash, is attached around the windshield (2).
[0013]
The lower corner of the rear part of the windshield (2) is attached with the fixture (10) to the lower corner of the window hole (1a), that is, the butt of the horizontal trim (6) and the vertical trim (5). It has been.
[0014]
3 to 6 show a fixture (10) used to fix the single glass windshield (2).
As shown in detail in FIGS. 3 and 4, the fixture (10) has side pieces (11) and (12) facing each other in parallel with an interval (d) corresponding to the thickness of the windshield (2). Have. The side pieces (11) and (12), which are windshield holding parts, are connected by the connecting piece (13), and the side pieces (11) and (12) and the connecting piece (13) are the rear lower corners of the windshield (2). It has an L shape extending in the vertical direction and the horizontal direction so as to receive the portion.
[0015]
A protruding piece (14) extending downward and rearward is provided at the corner of the side piece (11), and a lower part and a rear part of the side piece (12) are extended portions extending downward and rearward. (12a) is formed.
In addition, on the lower edge and the rear edge of the outer surface of the side piece (11), a flange portion (15) that protrudes outward in a rib shape is formed.
The fixture (10) having such a shape is preferably a molded product of a synthetic resin material.
[0016]
As shown in FIG. 5, the trims (5) and (6) that are abutted at the rear lower corner are provided with slit-like notches (16) at the ends thereof. The position of the notch hole (16) is the distance from the side edge of the trim (5) (6) to the side piece (12) to the projecting piece (14) (in this embodiment, equal to the distance (d)). There is a middle part of the trim.
[0017]
As shown in FIGS. 5 and 6, the windshield glass holding portion (both side pieces (11) and (12)) of the fixture (10) is fitted into the rear lower corner of the windshield (2), and the fixture (10) The projecting piece (14) is inserted into the notch hole (16) of the trim (5) (6). Then, the inner surface of the extension part (12a) of the side piece (12) comes into contact with and aligns with the outer surface of the side plate (1).
If it does in this way, extension part (12a) and protrusion (14) will engage with notch hole (16) of inner side board (3) and trim (5), (6), ie, fixture (10). Are engaged with each other with the side plate (1) interposed therebetween, whereby the windshield (2) is firmly held at the lower corner.
The upper end and the lower end of the front surface of the windshield (2) are locked by another mounting structure, but since this is not directly related to the present invention, detailed description thereof is omitted.
[0018]
The fixture (10) shown in FIG. 7 is a modification in which the windshield glass (2) is a pair glass, and the interval (d) for accommodating the windshield glass (2) is increased. However, the projecting piece (14) is at the same distance from the side piece (12) as in the previous embodiment.
FIG. 9 shows a state in which the pair glass is attached by the fixture (10) of FIG.
[0019]
The fixture (10) shown in FIG. 8 is a modification in the case where the windshield glass (2) is a three-piece glass. In this case, the interval (d) is made longer than in the case of FIG. FIG. 10 shows a state in which the windshield glass (2) having a three-piece structure is attached using the fixture (10).
[0020]
【The invention's effect】
According to invention of Claim 1, since the peripheral part of a notch hole is not exposed outside, it looks good. Moreover, even if the thickness of a windshield glass changes with single glass, a pair glass, 3 sheets glass, etc., the same thing can be used for a side plate by changing a fixing tool. Further, the windshield can be easily attached without using bolts or the like.
[0021]
According to invention of Claim 2, the clearance gap between the trim of a side plate and a fixing tool hides, and the appearance from a side surface becomes good. In addition, since the projecting piece and the extended portion have a structure in which the side plate is sandwiched from the windshield glass holding portion, the attachment becomes strong.
[0022]
According to the invention of claim 3, the windshield glass holding part and the protruding piece may be flush with each other due to manufacturing restrictions, but the peripheral part of the notch hole is formed by forming a collar part. Can be hidden.
[0023]
According to the invention described in claim 4, since the projecting piece protruding from the fixture is fitted into the cutout hole, it is not necessary to form the trim as a single piece. By dividing the trim, manufacturing is facilitated, storage space is small, and inexpensive.
