The quantity can be approximately zero. Further, by adjusting the angle at which the upper end 50B of the cover 50 is directed toward the cool air discharge port 12, the amount of cool air discharged from the cool air discharge port 12 into the space 9A on the uppermost shelf 3 is increased. On the other hand, the amount of cool air discharged into the space 9A can be reduced by adjusting the angle further rearward.

  With the above configuration, a case will be described in which a commodity S whose sales time zone is restricted by a pharmaceutical law such as pharmaceuticals is displayed on a specific shelf 3 and in the uppermost shelf 3 in this embodiment. In this case, in a time zone in which the product S can be sold, the space 9A on the uppermost shelf 3 is opened forward like the other shelves 3. As a result, any product can be selected and taken out by the customer.

  On the other hand, in the time zone in which the sale of the product S is restricted, first, the cover 50 is attached to the front end of the specific shelf 3 on which the product S is displayed, in this case, the uppermost shelf 3 as described above. . At this time, the front end portion of the shelf 3 is inserted and engaged from the front between the lower flange 51 and the upper wall 52A of the holding member 52.

  Then, by rotating the key of the locking device 45 provided on the cover 50, the engaging pin 46 rotates and engages with the engaging hole 42 provided on the shelf 3 side to enter the locked state. Accordingly, the cover 50 is attached to the front end of the shelf, and the forward movement is restricted by the engagement between the engagement pin 46 and the engagement hole 42 on the shelf 3 side. Removal of 50 is prohibited.

  In a state where the movable shelf 24 is stored in the display chamber 9, the cover 50 is fixed to the shelf 3, and the upper end thereof is provided close to the cool air discharge port 12 (upper edge of the front opening 2). As a result, the front portion of the space 9A on the uppermost shelf 3 is closed by the cover 50, and the sale-restricted product S displayed on the shelf 3 can be prevented from being taken out. .

  Therefore, as an example, even for a product S whose sales form is restricted by the Pharmaceutical Affairs Law or the like, the cover 50 covers a specific shelf 3 on which the product S is displayed, in this case, the space 9A on the uppermost shelf 3. By closing it, it is possible to avoid the inconvenience that the customer arbitrarily takes out the product S for sale. Thereby, the suitable display sales form according to the said goods S is realizable.

  Thereby, the space front part on the specific shelf 3 which has not only the uppermost shelf 3 but the guard 41 which has the engagement hole 42 in the front end part can be made into the state selectively closed by the cover 50. It becomes. Therefore, without limiting to the display pattern of the product S, only the space on the specific shelf 3 can be selectively closed by the cover 50, and smooth and appropriate display sales can be realized.

  In particular, in the present embodiment, since the lock device 45 that disables the change from the closed state of the front portion of the space 9 on the shelf 3 to the opened state by the cover 50 is provided, the space 9A on the shelf 3 is provided. By locking with the locking device 45 in a state where the front portion is closed, the closed state can be strictly maintained, and the front portion is closed by intentionally removing the cover 50 by a customer or the like. It is possible to reliably avoid the inconvenience that a product or the like is arbitrarily taken out from the shelf 3 in a damaged state.

  A cover 50 is attached to the front end of the shelf 3, and the locking device 45 is configured to detachably engage with the shelf 3 and prohibit the removal of the cover 50 from the shelf 3 in the locked state. Therefore, it is possible to avoid the disadvantage that the cover 50 is removed from the shelf 3 and the commodity on the shelf is taken out with a simple configuration. In this embodiment, the locking device 45 is provided on the cover 50 side. However, the present invention is not limited to this, and the locking device 45 is provided on each shelf 3 side to prohibit the removal of the cover 50. Also good.

  The cover 50 attached to the shelf 3 operates the stopper 30 for allowing and restricting the movement of the front handle of the movable shelf 24 in a state where the movable shelf 24 of the shelf 3 is housed in the display chamber 9.

Therefore, it is possible to improve product display / replenishment workability and locking workability on the shelf 3.

  In the present embodiment, the operation cover portion 55 is configured to cover the operation portion 30C of the stopper 30 from the front and the lower side, but is not limited to this, for example, the operation of the stopper 30 or The operation cover portion 55 may be inserted between the lower surface of the shelf 3 and the operation portion 30C of the stopper 30 so as to prohibit the operation, and the operation of the operation portion 30C may be prohibited.

  Also by this, the stopper 30 of the movable shelf 24 is deliberately operated, and the movable shelf 24 is pulled forward, so that it is possible to prevent the inconvenience that the products on the shelf 3 are taken out. Therefore, even if the shelf 3 is a movable shelf 24 that can be pulled out, strict product management can be realized.

  In the present embodiment, the cover 50 attached to the front end of the uppermost shelf 3 is provided with the upper end 50 </ b> B directed toward the rear of the cold air outlet 12. Therefore, a part of the cool air curtain formed from the cool air discharge port 12 formed at the upper edge of the opening 2 of the display chamber 9 toward the cool air suction port 13 formed at the lower edge of the opening 2 is the uppermost shelf 3. By flowing down along the front surface of the cover 30 provided at the front end of the cover, the front surface of the cover 50 is cooled by the air curtain, so that condensation occurs on the front surface of the cover 50 and wets the display chamber 9. Inconvenience can be avoided.

  Further, a part of the cold air curtain can be caused to flow down along the front surface of the cover 50 by the Counder effect, and the inconvenience that the internal temperature rises due to the disturbance of the cold air current can be avoided.

  In particular, in the present embodiment, the upper part of the cover 50 is inclined rearward, so that the cold air forming the air curtain can flow smoothly along the upper front surface (inclined surface 50A) of the cover inclined rearward. Can do.

  Further, by adjusting the directivity angle of the upper end 50B of the cover 50 to the cool air discharge port 12, the amount of cool air that forms a cool air curtain that flows down the front surface of the cover 50 and the top shelf that flows down to the rear surface of the cover 50 are displayed. 3 can adjust the amount of cool air flowing into the space 9A. Thereby, since the amount of cold air supplied into the space 9A can be adjusted, the cooling temperature of the space 9A can be adjusted with high accuracy.

  Further, the upper end 50B of the cover 50 is directed to the rear of the cold air outlet 12 so that the flow of the cold air curtain formed by being discharged from the cold air outlet 12 and sucked into the cold air inlet 13 is not diverted. Can do. Thereby, all the cool air curtains flow down along the front surface of the cover 50, thereby preventing the occurrence of condensation on the front surface of the cover 50.

  In this case, cold air is not supplied from the front into the space 9A on the uppermost shelf 3 on the rear surface of the cover 50. In the present embodiment, however, the partition plate 8 provided behind the display chamber 9 is provided with punching. Since the plurality of cold air blowing holes 10 are formed, the cold air is blown out from the cold air blowing holes 10 communicating with the inside of the duct 11, and the space 9A can be smoothly cooled.

  When the cover 50 is changed from a state in which the front of the space 9A on the shelf 3 is closed to a state in which the space is opened to the front, a lock is inserted into the locking device 45 and rotated so that the engagement pin 46 and the engagement hole 42 on the shelf 3 side are disengaged. And it becomes possible to change to the open state by pulling the cover 50 forward from the shelf front end.
