Abstract

(57) [Abstract] [PROBLEMS] To prevent the surface of a door body from being scratched or deformed due to opening and closing. In this device, a front curved plastic door body is attached to a front portion of a display case, and the door body is put into and removed from an upper space of the display case to open and close.
The present invention relates to a door device in a display case, and is characterized in that a thin ridge extending in the opening / closing direction is provided on the surface of the door body. The ridge may be singular or plural, but it is preferable to provide the ridge at a substantially central portion in the surface width direction of the door body. The ridge makes sliding contact with other members of the case body, and the surface of the door body does not come into direct sliding contact.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention mainly relates to a device for preventing the surface of a plastic opening / closing door from being scratched or deformed in a heated display case for canned beverages.

[0002]

[Prior art]

 A case shown in Fig. 4 is known as a case for displaying and storing canned beverage while heating. This case has a display shelf with a built-in heater inside the case body, and is provided with a transparent plastic opening / closing door A curved in an arc shape on the front surface of the case body. The opening / closing door A is pivotally supported by slide hinges at both ends, and by opening and closing a handle B for opening / closing operation provided at a substantially lower end of the opening / closing door A, the opening / closing door A is slid and opened in an upper space in the case body. Further, the case body C has a falling wall D formed on the upper front surface to secure a space for accommodating the illumination lamp in the front part of the upper space.

[0003]

[Problems to be solved by the device]

 Since the opening / closing door A is made of plastic and is housed in the upper space of the case main body C, repeated opening / closing operations scratch the surface by rubbing the lower end of the falling wall D. To be Such scratches significantly impair the commercial value of the display case. It is conceivable to apply a hard coat treatment to the surface of the door A to avoid this, but this will increase the cost and still fail to exert a sufficient protective effect. There is also a means for preventing the front part from being damaged by opening / closing the opening / closing door A while maintaining a gap that does not make sliding contact with the opening / closing door A and the constituent members of the case body C. There is a problem that the heating atmosphere is adversely affected, dust easily enters, the efficiency of the storage space for the canned beverage in the case body becomes inefficient, and the appearance also deteriorates.

Further, in the case of a horizontally long case body, the opening / closing door itself may be deformed if the unreasonable opening / closing operation continues.

An object of the present invention is to provide a plastic door device for a display case, which can prevent the surface from being scratched or deformed when the door is opened or closed.

[0006]

[Means for solving problems]

 The present invention is characterized in that the following configuration is provided in order to solve the above-mentioned problems of the conventional technology.

That is, this device is a door in a display case in which a front curved plastic door main body is attached to the front surface of the display case, and the door main body is inserted into and removed from the upper space of the display case to open and close. It is related to the device and is characterized in that a thin ridge extending in the opening and closing direction is provided on the surface of the door body.

It does not matter whether the ridge is single or plural, but it is preferable to provide it in a substantially central portion in the surface width direction of the door body.

[0009]

[Best Mode for Carrying Out the Invention]

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 and 2 are a perspective view and a sectional view of a can and beverage display case to which a door device according to an embodiment of the present invention is applied. Reference numeral 1 in the figure is a case body of the display case, which is in the shape of a box with a deep, horizontally long front surface. Reference numeral 2 denotes a falling wall that is provided at the upper end of the front surface of the case body 1, and an illumination lamp 4 such as a fluorescent lamp is housed in the internal space 3 of the falling wall.

Reference numeral 5 denotes an opening / closing door made of a transparent plastic which is curved forward, and both left and right ends 5a are supported by a slide type hinge 6 (see FIG. 2), so that the lighting lamp storage space 3 It is put into and taken out from the upper space 7 of the case body on the back side.

Reference numeral 8 denotes a linear ridge projectingly formed at the center of the surface of the opening / closing door 5 in the width direction, and extends in the opening / closing direction of the opening / closing door 5, that is, in the vertical direction in this embodiment. The thickness of the protrusion 8 is set within a range that does not hinder the opening and closing of the opening / closing door 5. Reference numeral 9 is a handle formed on the lower portion of the opening / closing door 5.

Therefore, when the opening / closing door 5 is lifted by holding the handle 9, the opening / closing door 5 is rotated upward with the hinge 6 as a fulcrum and is housed in the housing space 7 above the case body 1. At this time, the opening / closing door surface 5b moves so as to face the lower end 2a of the falling wall and the inner surface of the top plate 10. However, since the protrusion 8 projects from the opening / closing door surface 5b, Even if the lower end 2a of the falling wall or the inner surface of the top plate is rubbed, the lower end 2a of the falling wall or the inner surface of the top plate is in sliding contact with the ridge 8 and is not in direct contact with the opening / closing door surface 5b. This prevents the opening / closing door surface 5b from being scratched. Further, since the ridges 8 also serve as reinforcing ribs of the opening / closing door 5, the opening / closing door is not deformed even if it is roughly opened and closed.

It should be noted that the protrusions may have various widths and numbers depending on the size of the case body or from a design point of view, such as a plurality of protrusions provided at the central portion of the surface of the opening / closing door or one at each side edge. It is possible to set modes such as.

[0014]

[Effect of device]

 As described above, according to the present invention, since the ridge extending in the opening / closing direction is provided on the surface of the door body, the surface of the ridge makes sliding contact with the lower end of the falling wall on the front of the case body when opening / closing. The surface of the main body is not brought into sliding contact with these members. Therefore, it is possible to prevent the surface of the door from being scratched and scratched.

Further, the ridges serve as reinforcing ribs on the door surface and increase the strength of the door body, so that the deformation thereof can be prevented as much as possible even if forced opening and closing is performed.
