  • Patent number: 8157336
    Abstract: There is disclosed a showcase in which a width of a transparent door can be extended to substantially the whole width of a main body even in a case where a locking device is incorporated in a handle of a transparent door. A low-temperature showcase comprises the transparent door which is rotatably supported on the main body on one side so as to openably close an opening of the main body including a showroom, the handle disposed at an outer surface of this transparent door on an unsupported side, and a locking device disposed in this handle. The locking device has a keyhole, a rotary shaft which rotates concentrically with a key by a rotating operation of the key inserted into this keyhole and a hook which is attached to this rotary shaft so as to disengageably engage with the main body, and the keyhole is disposed at a side surface of the handle on a supported side of the transparent door.

  • Patent number: 8104302
    Abstract: There is disclosed a low-temperature showcase in which dew condensation water from outer surfaces of transparent walls is securely treated and in which air can smoothly be blown from a mechanical chamber to the outer surfaces of the transparent walls. The low-temperature showcase includes a showroom having the transparent walls, the mechanical chamber constituted under this showroom, and a cooling unit constituted of a compressor, a condenser, a fan for the condenser and the like arranged in the mechanical chamber. The low-temperature showcase further comprises blow-off portions which are formed at lower portions of the transparent walls and which blow air discharged from the fan for the condenser in the mechanical chamber toward outer surfaces of the transparent walls, and water receiving portions which are defined between the blow-off portions and the outer surfaces of the transparent walls and which allows inflow of dew condensation water flowing down along the outer surfaces of the transparent walls.

  • Patent number: 7162885
    Abstract: There is provided a showcase which can expand a goods mounting area of a rack within a range of no interference with cooling in a display room. The showcase comprises a display room surrounded with a transparent wall supported by support pillars erected at four corners of a bottom frame, and a door, a rack hung in the display room to display goods, a cold air outlet formed on one side of the bottom frame, and a cold air inlet formed on the other side of the bottom frame. A space between the transparent wall of the other side of the display room and the rack is narrower than a space between the transparent wall of one side of the display room and the rack.
