Description

[Detailed description of the invention] The present invention relates to a structure in which a magnetic packing is attached to the periphery of the opening of a case opened and closed by a door, such as a cold or heat insulation case, or to a door frame that abuts the opening periphery. The objective is to provide a mounting structure that requires fewer screws and is highly durable.

Hereinafter, embodiments of the present invention will be described with reference to the drawings while comparing them with conventional examples.

FIG. 1 is a perspective view of a refrigerated case 1 in which a product display space is covered with transparent glass, and a door 3 is rotatably supported at the front opening.

In order to seal the inside of the case in such a show case, the periphery of the front opening and the door frame that abuts the periphery of the opening are usually equipped with a magnetic metal plate on one side and a magnetic gasket on the other side that attracts the plate. are installed on each side to maintain a sealed state when the door is closed.

Figure 2 is a cross-sectional view of a conventional mounting structure in which a magnet packing is attached to the peripheral edge of the front opening. The net packing 4 is fixed by screws 7 while being pressed against the mounting location by a holding plate 6 having a square cross section.

However, in such a mounting structure, since the magnetic packing 4 is made of soft resin material,
If the number of screws is not increased, as shown in Fig. 3, undulations will be formed in the magnetic packing 4, making the sealing condition worse when the door is closed, and the same problem will occur if the screws are loosened. There were some drawbacks.

The present invention provides a mounting structure that can overcome these drawbacks even with a small number of screwed parts, and this will be explained below.

FIG. 4 is a cross-sectional view showing the mounting structure of the magnetic packing according to the present invention. A groove 4a is provided in the length direction, and the cross section for holding the groove is omitted.
The shaped holding plate 6 has a protrusion 6a that fits into the groove 4a and a flange 6b at its tip, and is screwed with screws 7 with the protrusion 6a fitted into the groove 4a. It is.

That is, the magnetic packing 4 and the holding plate 6
is integrally fixed by screws to the support column 8 which is fixed to the base of the case body by screws. At this time, since the holding plate 6 has a cross-sectional shape,
It performs two functions: holding down the gasket 4 and regulating the case opening edge. Reference numeral 9 denotes a glass support frame which is fixed to the column 8 together with a decorative frame 10 by screws.
Reference numeral 11 indicates a fluorescent lamp, and this fluorescent lamp 11 is attached to the pressing plate 6 by a fluorescent lamp support plate 12.
13 is a magnetic metal plate.

Here, the protrusion 6a securely presses the lower mounting plate of the magnetic packing 4 and brings it into close contact with the mounting location.
In addition, the flange 6b abuts against the side plate between the upper seal portion and the lower mounting plate of the magnetic packing 4, causing the magnetic packing 4 to extend straight in the length direction, and also serves as a reinforcement for the protrusion 6a. As a result, even if there are only a few screwed parts, the above-mentioned undulations will not occur, making the installation work easier, and even if some parts become loose, undulations will not occur.

FIG. 5 shows another embodiment of the present invention. In order to improve the engagement between the magnetic packing 4 and the holding plate 6, the magnetic packing 4 is provided with a protrusion 4b having a fin to prevent it from coming off. The holding plate 6 is formed with a recess 6c that fits into the protrusion 4b.

In any of the embodiments, the magnetic packing 4 and the pressing plate 6 can be easily obtained by extrusion molding a soft resin material and a soft resin material, respectively. It goes without saying that the present invention is applicable not only to the refrigerated case shown in FIG. 1, but also to any case that uses magnetic packing.

Claims (1)

[Scope of utility model registration request] The case has a substantially U-shaped cross section and has two opposing plates, one of which has a sealing part housing a rod-shaped magnet, the other of which is attached to the periphery of the opening of the case that is opened and closed by the door. In the structure for attaching a soft resin packing serving as a mounting plate, a hard resin holding plate having a substantially square cross section is used to tightly fix the mounting plate to the peripheral edge of the opening. A groove is formed in the U-shaped corner of the mounting plate in the length direction, and the tip of the holding plate has a protrusion that is perpendicular to the plate surface and is to be fitted into the groove, and a protrusion on the opposite side to the protrusion. A flange extending in the length direction and to be abutted against a plate connecting the two plates of the packing is formed, and with the holding plate stacked on the mounting plate, the flange is attached to the peripheral edge of the opening. The mounting structure of the magnetic packing is fixed with screws.
