BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door structure such as a refrigerated or warm storage showcase.

[0002]

2. Description of the Related Art In a conventional refrigerated or warm storage showcase, as shown in FIG.
When the sliding door 4 is closed and the sliding door 4 is closed, the door gasket 6 attached to the vertical frame member 5 of the sliding door 4 comes into close contact with the side rail 3 and seals the inside of the refrigerator 7 from the outside of the refrigerator. From the viewpoint, it is necessary that the side rail 3 and the vertical frame member 5 overlap to a certain extent in the width direction, so that the width (height as a rail) of the side rail 3 must be increased. Therefore, the frontage 8 of the showcase between the left and right side rails 3 is so narrowed that there is a problem that it is inconvenient to put goods in and out of the compartment 7.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a sliding door in which the height of a side rail can be reduced and a frontage can be increased.

[0004]

[SUMMARY OF To this end, the sliding door, such as a showcase according to the present invention, the above-side when the frame member side end portion facing the side rail, the sliding door mounted on the side end closed and it has a projection located on the side of the extending beauty above SL door gasket toward the side rails from the side end portion of the door gasket and the frame member is disposed straddling the end portion and the side rail .

[0005]

Therefore, when the sliding door is closed, the overlap between the sliding door and the side rail is increased by the length of the projection extending from the side end of the frame member toward the side rail, so that the height of the side rail is reduced. Even so, the effect of heat insulation between the sliding door and the side rail can be sufficiently performed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; In FIG. 1, a channel-shaped side rail 10 is fixed vertically to an inner surface 2 of a front edge of a refrigerated or warmed showcase main body side wall 1, and a steel plate 11 is embedded in a bottom surface thereof.

[0007] Vertical frame member 1 made of hard vinyl chloride for sliding door 4
2, a soft resin door gasket 6 is attached to the side end portion 13, and when the sliding door 4 is closed, the magnet 14 embedded in the front end portion of the door gasket 6 is attracted to the steel plate 11 of the side rail 10, The door gasket 6 comes into close contact with the side rail 10 and seals the inside 7 of the warehouse against the outside of the warehouse. On the other hand, a pair of protrusions 15 extending toward the side rail 10 along the inside and outside of the door gasket 6 are provided at the side end 13 of the vertical frame member 12 to the full height of the vertical frame member 12.

Therefore, when the sliding door 4 is closed as shown in FIG. 1, the overlap between the side rail 10 and the sliding door 4 in the lateral width direction is increased by the projections 15 as compared with the conventional case, and the effect of heat insulation between the two is provided. Is performed sufficiently, the height of the side rails 10 is reduced, and the showcase frontage 8 between the left and right side rails 10 is increased accordingly,
It is possible to easily put goods in and out of the compartment 7.

Further, the provision of the projections 15 reduces the gap between the sliding door 4 and the bottom surface of the side rail 10 while ensuring the dimensions of the door gasket 6 in the lateral width direction, thereby improving the heat shielding function at this portion. This can increase the cooling or warming effect of the showcase. Therefore, in the case of a refrigerated showcase, cooling of the outside portion of the side rail 10 is suppressed, and
There is an advantage that dew condensation hardly occurs on the surface. further,
Since the outside of the door gasket 6 is partially covered with the projection 15, the appearance of the sliding door 4 that is opened and closed is improved accordingly.

In the above embodiment, a pair of protrusions 15 are provided along the inner and outer sides of the door gasket 6 at the full height of the vertical frame member 12, but the vertical frame member is apt to allow heat to enter and exit. The protrusions are provided below or above 12 so that the protrusion of heat is relatively unlikely to occur, or the protrusions are provided only on one of the inside and outside, so that the heat can be shut off. The same effect can be obtained even if the projection provided on the frame member is applied to a sliding door which opens and closes the upper surface of a showcase or the like substantially horizontally.

Further, when the door gasket is attached to the side rail side and the sliding door is closed and the door gasket abuts on the frame member side end, a projection provided on the frame member side end is formed on the side of the door gasket. In the same manner as described above, so that heat is interrupted between the side rails.

[0012]

According to the present invention, the sliding door of a showcase or the like can reduce the height of a side rail by a projection provided at a side end portion of a frame member to easily increase a frontage of the showcase or the like. Since it is possible, it is convenient to put products in and out of the showcase and the like, and the protrusions make the heat insulation between the sliding door and the side rails better, so that the merchantability of the showcase and the like can be further enhanced.
