Description

  The present invention relates to a building opening covering device.

  For example, an opening is provided in a building such as a distribution freezer, and a vehicle body opening at the rear of a truck faces the building opening, and goods are carried in and out through these openings.

In recent years, there have been an increasing number of cases in which dock shelters are installed as a measure for preventing insects from entering through the openings. However, the air-type dock shelter covers the three directions on the upper side and the left and right sides of the opening, and has no cover on the lower side.
Since the vehicle body opening of the truck is at a certain height from the ground surface, the building opening is usually formed at a position higher than the ground surface, but the height of the vehicle body opening varies depending on the size of the vehicle body, A gap is likely to be generated between the lower end of the vehicle body opening (such as a truck bed) and the lower end of the building opening (such as a building platform).
In the structure of a normal dock shelter or the like, as described later, it is not possible to sufficiently prevent insects from invading or inflowing of outside air from the above-mentioned gaps by blowing air or the like.

  Therefore, in order to prevent outside air and insects from entering the freezer from this gap, a freezer entrance / exit shielding device has been proposed. This loading / unloading shielding device comprises a box-shaped storage container installed at the lower part of a building opening and having a long upper end opening in the width direction, and a bellows-shaped shielding plate that can be taken in and out of the storage container and can be folded. Thus, the front end of the shielding plate can be attached to the bottom of the building opening (Patent Document 1).
