Description

[Detailed description of the invention] This invention relates to a door opening/closing device for a storage warehouse etc. equipped with an automatic closing type door, which quickly removes water from the door, easily cleans the lower rail frame and track body, and The purpose is to make the rotating body run smoothly.

Below, an embodiment of the present invention will be explained with reference to the drawings. Fig. 1.2 Figure 1 shows a storage such as a refrigerated showcase whose main body is composed of an insulating wall 2 having an opening for taking in and taking out products on the front side. A plurality of shelves 4 are arranged in the refrigerator interior 3 defined by
, a cold air passage 8 in which a blower 7 is installed, and a machine room 9 formed at the bottom of the main body includes a compressor 10 that constitutes a refrigeration cycle together with the cooler. A condenser 11 and the like are installed, and the inside 3 of the refrigerator is cooled by forcedly circulating the cold air that has been heat exchanged by the cooler with a blower 7 as shown by the arrow in FIG.

12.12 is a sliding transparent door disposed in the front opening, and the iron door has a transparent body 12a made of glass or the like as a main body, and a handle fitted to the end face of the transparent body made of resin, aluminum, etc. 12 Vertical frame 12b with f, vertical frame 12C, and both horizontal frames 12
d and 12e, and fixtures 13.13' of different heights are provided on the lower surface of the horizontal frame 12e, and a rotating body 14.14' such as a wheel is rotatably pivoted to the fixture. .

Reference numerals 15 and 16 indicate upper and lower rail frames having a Y-shaped vertical cross section, which are disposed opposite to each other at the upper and lower ends of the front opening, and the iron frame is made of injection moldable resin or aluminum, preferably injected with resin that does not easily cause condensation. It is formed by molding and includes two parallel grooves 19.20 having through holes 18 serving as drainage holes at both ends, and two side walls 21, 22, 23 forming the grooves.

Reference numeral 24.25 shown in Figs. 3 and 4 is a metal track body with a zero-shaped vertical cross section and shorter horizontal dimension than the rail frame, and the rotary body 14.14' of the door is guided on the upper surface that slopes low to one side. A track section 26 and a stop section 27 that stops the rotating body 14' when the door is opened.
The track part 26 of one track body 24 is downward to the right, and the track part 26 of the other track body 25 is downward to the left so that the track parts intersect with each other when viewed from the front. It is removably fitted into both grooves 1, 9 and 20 of the rail frame 16.

28 and 29 are elastic bodies made of semi-hard rubber or the like, and grooves 1 are provided between one end of the track body 24, 25 located in the opening direction of each field, that is, one end on the stop portion 27 side, and the end on the opening side.
9.20, the handle 12f of the door 12.12 in the closed state is removably fitted in such a way that it protrudes in the lateral direction of the opening and upwardly from the upper end of the upper surface of the track portion 26 of the track body 24.25.

According to the above configuration, the track body 24 guiding the door 12.12
．． 25 are fitted into both grooves 19 and 20 of the lower rail frame 16, so even if the door is suddenly opened and closed, the side walls 21, 22, 23 act as guides for the horizontal frame 12e, and the track section 26 It is possible to prevent the rotating body 14.14' from falling off from the side walls 21, 22 during injection molding of the lower rail frame 16, and to return the rotating body 14.14' to a predetermined position by tilting the track section 26 toward the center. Even if a slight distortion occurs in .23 and the spacing between both grooves 19.20 becomes uneven, this distortion can be corrected by fitting the raceway body 24.25.
In addition, by removing the track body 24.25 from both grooves 19.20, the lower rail 16 and the track body 24.25 can be easily cleaned.

In addition, the track portion 26 of the track body 24 and 25 having a zero-shaped longitudinal section
is inclined low in one direction, so the door closing time rotation body 14.
Not only can the door 12.12 be automatically closed by automatically guiding the door 14' downward, but also the dew from the door 12.12 can be quickly drained through its center.

As mentioned above, the present invention has two slidable doors in the opening for taking products in and out of the warehouse, and upper and lower rail frames each having two parallel grooves. A track body having a zero-shaped vertical cross section, which has a track part for guiding the rotating body of the door formed on the upper surface that slopes low, is placed in both groove parts of the lower rail frame so that the inclinations of the track parts are in opposite directions. Since they are fitted together removably, it is possible to prevent the rotating body from falling off the track when the door is suddenly opened/closed, and to keep the rotating body at a predetermined position on the track. The lower rail frame and track body, where dust tends to accumulate, can be cleaned easily by removing the track body. Furthermore, the dew that adheres to the door can be received by the track section without scattering into or out of the refrigerator, and can be quickly drained due to the inclination of the track section.
