Description

  The present invention relates to a showcase in which a sliding door is provided in an opening of a main body case having a storage portion for storing products.

There is a frozen showcase in which a product such as ice cream is stored in a display room in the main body case and the product displayed in the cabinet is easily seen by customers and the like, and a transparent sliding door is provided in the opening. This type of showcase has a structure in which a transparent sliding door is opened and closed by sliding in the width direction at the opening. In addition, in order to enhance the display effect of the product, there is also a structure in which the opening is inclined downward from the back side toward the near side, and the sliding door is opened and closed by sliding in the width direction at the opening. is there.
As shown in, for example, Japanese Patent Application Laid-Open No. 2007-14593 (Patent Document 1), this type of showcase is used to prevent an increase in heat load due to intrusion of outside air into the cabinet and a decrease in heat retention performance. The upper surface opening is closed so as to be opened and closed by a slidable sliding door type transparent door made of transparent glass or hard resin.
Also, in this type of showcase, in order to make it easier for customers to see the products displayed in the warehouse, there is a tendency to abolish the central column that partitions the center of the opening and the doors abut against the left and right doors. As disclosed in JP-A-8-100706 (Patent Document 2), a door stopper is used in place of the conventional central column.

  In this showcase, by moving the two doors on the center side in the width direction to both ends in the width direction, the center side in the width direction of the opening can be opened to the size of two sliding doors. However, since the door stopper is provided at the center in the width direction of the opening, one end or the other end in the width direction of the opening can be opened only to the size of one sliding door. For this reason, compared with the width direction center side of an opening part, goods cannot be taken in or out easily in the width direction one end side or the other end side, and workability | operativity at the time of goods replenishment falls. Moreover, if the sliding door is removed, one end side or the other end side in the width direction of the opening can be opened widely. However, due to its size and weight, the sliding door not only takes time for removal work but also may be damaged when removed. Therefore, the work by removing the sliding door was not preferable.

The height H1 (for example, approximately 15 mm) in the thickness direction is processed to be higher than the height H2 (for example, approximately 10 mm) in the thickness direction of the doors on the opposite non-contact surfaces 27b and 37b. In addition, the dimension L in the opening / closing direction of the door of the projecting pieces 27 and 37 is approximately 40 mm, and the dimension W in the direction perpendicular thereto is approximately 20 mm. By adopting such an inclined shape, the contact area between the projecting pieces 27 and 37 and the lower doors 10 and 40 is increased to reduce the impact at the time of contact, and the volume of the projecting piece is reduced to reduce the cost. be able to.
Further, screw holes (spot facing) 27c and 37c for fixing the projecting pieces 27 and 37 with screws (not shown) are provided in the vicinity of the non-contact surfaces 27b and 37b.
In addition, in this Embodiment, as shown to FIG. 4 (B), it corresponds to the case where the shape of the upper doors 20 and 30 which attach the protrusions 27 and 37 is a flat plate. Therefore, the protrusions 27 and 37 are processed so that the contact surface 27d (37d) with the upper doors 20 and 30 is a flat surface.
Next, referring to FIG. 5, a projecting piece (contact portion) 37 that contacts the left end vertical frame 49 of the frame frame 41 of the lower door 40 is arranged on the back surface of the frame frame 31 on the handle 36 side of the upper door 30. The method of setting will be described. Note that a method of disposing a protrusion piece (contact portion) 27 that contacts the right end vertical frame 19 of the frame frame 11 of the lower door 10 on the back surface of the frame frame 21 on the handle 26 side of the upper door 20 is the upper door 30. Therefore, only the case where the protruding piece 37 is disposed on the upper door 30 will be described below.
As shown in FIG. 5, the projecting piece 37 is disposed on the back surface of the upper door 30 on the handle 36 side, near the lower edge 31 b of the frame frame 31, along the end surface 35 a of the left end vertical frame 35. The projecting piece 37 is disposed at a predetermined distance from the lower edge 31 b of the frame 31. The predetermined distance may be determined at a position that does not interfere with the upper rail 7b when the upper door slides and moves on the upper rails 7a and 7b. Further, as shown in FIG. 1, the projecting pieces 27 and 37 are the back surfaces of the glass plates 28 and 30 on the handles 26 and 36 side of the upper doors 20 and 30, and are not easily visible through the glass so that they do not stand out. In addition, it is desirable to provide at a lower position.

In this case, the protrusions 27 and 37 may be configured along the curved shape of the upper doors 20 and 40 to be attached.

Next, with reference to FIG. 6, FIG. 7 (A), (B), the mechanism by which the collision of an upper door and a lower door is eliminated with the protrusions 27 and 37 is demonstrated.
FIG. 6 is a view of a state in which the protruding piece 27 disposed on the back surface of the upper door 20 is in contact with the right end vertical frame 19 of the frame frame 11 of the lower door 10 as viewed from the right side of the main body 2. The height in the thickness direction of the upper door of the protrusion 27 (H1 dimension in FIG. 4B) is more than half of the thickness of the lower door with the upper door 20 and the lower door 10 placed on the guide rails 100 and 101. And it is desirable to make it the dimension which becomes less than the thickness of a lower door. By setting it as such a dimension, it is possible to avoid the protruding piece 27 riding on the lower door 10 or coming into contact with the lower rail 8b. In addition, although the protrusion piece 27 was demonstrated above, it is the same also about the protrusion piece 37. FIG.
FIG. 7 is a schematic diagram showing the open / closed state of the upper doors 20 and 30 and the lower doors 10 and 40. FIG. 7A shows the upper door 30 and the lower door 40 with the right half of the opening 4 closed. FIG. 7B shows a state in which the upper door 30 and the lower door 40 are opened in the right half of the opening 4.
In the state in which the opening 4 is closed, as shown in FIG. 7A, the right end vertical frame 45 of the frame frame 41 of the lower door 40 is in contact with the glass side plate 13. The left end vertical frame 49 of the frame frame 41 overlaps the right end vertical frame 39 of the upper door 30. The left end vertical frame 35 of the upper door 30 is in contact with the right end vertical frame 25 of the upper door 20 (not shown).
For example, when the lower door 40 is moved in the direction of arrow P and the upper door 30 is moved in the direction of arrow Q, the upper door 30 and the lower door 40 are released as shown in FIG. In this state, the right end surface 37a of the protruding piece 37 of the upper door 30 and the end surface 49a of the left end vertical frame 49 of the lower door 40 come into contact with each other.
At this time, an interval A that substantially coincides with the dimension L in the door opening / closing direction of the projecting piece 37 is formed between the end surface 39a of the right end vertical frame 39 of the upper door 30 and the handle 46 of the lower door 40.

  Although not shown, the same applies to the lower door 10 and the upper door 20. When the lower door 10 and the upper door 20 are released, the contact surface 27a of the projecting piece 27 and the end surface 19a of the right end vertical frame 19 of the lower door 10 come into contact with each other, and the left end vertical frame 29 of the upper door 20 Between the handle 16 of the left end vertical frame 15 of the door 10, an interval A that substantially coincides with the dimension L in the door opening / closing direction of the protrusion 27 is formed.

As described above, according to the present embodiment, the following effects are obtained.
In this showcase 1, each door 10, 20, 30, 40 is disposed on the inclined opening surface, and the frame of each door 10, 20, 30, 40 is completely above the upper rail 7 or the lower rail 8. It is released in a sliding manner. In other words, the doors 10, 20, 30, 40 are opened in a sliding manner with their own weights hanging on the upper rail 7 or the lower rail 8. In this configuration, the mounting positions of the protrusions 27 and 37 described above are limited to some extent, but in this embodiment, the rear surfaces of the glass plates 28 and 30 on the handles 26 and 36 side of the upper doors 20 and 30, respectively. Since the protrusions 27 and 37 are provided at positions below the back surface, the protrusions 27 and 37 are difficult to see through the glass and can be made inconspicuous.
Even in a state where the mounting positions of the projecting pieces 27 and 37 are limited to some extent, the projecting pieces 27 and 37 are configured at the above-described positions, so that the lower door 10 and the upper door 20 are completely overlapped. When the portion 4 is opened, the end surface 29a of the left end vertical frame 29 of the upper door 20 and the handle 16 provided on the left end vertical frame 15 of the lower door 10 do not collide. Therefore, the collision more than necessary with respect to the handles 16 and 46 can be suppressed, and the durability of the handles 16 and 46 can be improved without applying a load to the handles 16 and 46. Moreover, since the space | interval A is formed between the end surface 29a of the left end vertical frame 29 of the upper door 20, and the handle 16 provided in the left end vertical frame 15 of the lower door 10, the upper door 20 and the lower side Even when the doors 10 are overlapped, the inconvenience at the time of collision of the doors 10 and 20 can be avoided.
The above operation and effect are the same when the opening 4 is opened so that the upper door 30 and the lower door 40 overlap each other.

Moreover, according to this Embodiment, the protrusions 27 and 37 are comprised so that it may become substantially transparent. With this configuration, when the opening 4 is opened and closed, the protruding pieces 27 and 37 seen from the user through the upper door are inconspicuous and are difficult to see.
Therefore, even if it takes the structure which arrange | positions the protrusions 27 and 37 on the back surface of a glass plate, the beauty | look of the door of the showcase 1 is not impaired.
In addition, according to the present embodiment, the protrusions 27 and 37 themselves are small and inconspicuous with a substantially rectangular shape having a dimension L in the opening and closing direction of the door of approximately 40 mm and a dimension W in the direction perpendicular thereto of approximately 20 mm. Configured as a thing.
Therefore, even if it takes the structure which arrange | positions the protrusions 27 and 37, it is hard to visually recognize through a door, and the beauty | look of the door of the showcase 1 is not impaired.
Moreover, according to this Embodiment, the resin which uses a polypropylene as the raw material of the protrusions 27 and 37 was used. According to this, since the projecting pieces 27 and 37 are small and can be configured with a small amount, since the resin made of polypropylene is not expensive, the present embodiment can be realized at low cost.

  As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this embodiment. Since only one embodiment of the present invention is illustrated, changes and applications can be arbitrarily made without departing from the spirit of the present invention.

  For example, in the present embodiment, polypropylene is used as the material for the projecting pieces 27 and 37, but the material is not necessarily limited to polypropylene, and other materials such as polyethylene and EVA resin can also be used.

  Further, for example, the projecting pieces 27 and 37 are provided at one place in the lower position so that they are not easily visible through the glass and do not stand out, but may be provided at one place in the upper position. Further, the mounting positions of the projecting pieces 27 and 37 are not necessarily limited to one. You may arrange | position in two places of the upper part of the back surface of the glass plates 28 and 38, and a lower part, and may arrange | position in three places, the upper part, the center part, and the lower part of the back surface of the glass plates 28 and 38. In addition, other methods such as providing a rod-like contact portion so as to extend above and below the rear surfaces of the glass plates 28 and 38 can be used. Further, the projecting pieces 27 and 37 may be arranged so as to be hidden in the groove of the lower rail 8.

  Further, for example, when a glass plate having a transparency and a color is used for the glass plate of each door, it is also possible to use the protruding pieces 27 and 37 having a color that is consistent with the glass plate.

  Further, in the present embodiment, the lower door 10, the upper door 20, the upper door 30, and the lower door 40 are formed by fitting a glass plate into a frame frame, but may be configured by a glass plate without a frame frame. It is.
