No.). Japanese Utility Model Application Laid-Open No. 2-52081 discloses a structure in which a hook is provided on the inner wall surface of a handrail mall and a hook of a night cover is hooked on the hook, that is, a handrail mall is used as a hook. It is known. JP-A-3-10
No. 67 discloses a hooking structure using a sash as a hook. In this case, as shown in FIG. 5, a transparent plate glass 31 is erected on a bumper rail 30, and a sash 33 attached to the upper edge of the plate glass 31 via a packing 32 is used to cover the lower edge of the inner surface. The latch 35 of the cover 34 is hooked. The locking member 35 is formed integrally with a handle 36 for operating the night cover 34 for extension. [0003] In a hanging structure in which a hook for a night cover is fixed to a handrail molding or a cool air suction port, the hanging tool is inward from the handrail molding or the cold air suction port. , Which hinders taking in and out of products and cleaning. The number of parts is increased by the provision of a separate hook, and the installation requires extra labor. [0004] In a latching structure using a railing mall or a sash as a latch, the above-mentioned drawbacks can be eliminated and the number of parts can be reduced since the latching portion does not protrude. But,
If a hook is opened in the handrail mall and this is used as a hook, the lowered night cover is in the way and the hook cannot be seen. I have to. In addition, since the position of the hook in the left-right direction must be correctly aligned with the hook, the hook cannot be hooked quickly. In the latch structure using the sash as the latch, the latch can be latched anywhere in the longitudinal direction of the sash, so that it does not take much time to latch the night cover. However, since the hooks of the hooks are shallower to the sash and the hooks projecting forward from the lower end of the handle are hooked perpendicularly to the lower edge of the inner surface of the sash, the hooking state cannot be reliably maintained. For example, only the night cover swings in and out in response to the airflow of the air curtain, and the locking tool may come off the sash. By changing the cross-sectional shape of the sash, it is possible to increase the catching depth of the locking tool, but in that case, the catch must be extended inward along the longitudinal direction of the sash. Is a hindrance to putting products in and out. An object of the present invention is to provide a hanging part for hooking a hook of a night cover integrally with a handrail molding, so that the hanging part does not hinder the taking in and out of goods and cleaning. In addition, it is an object of the present invention to provide a night cover hooking structure in which a hook can be easily hooked on a hooking portion without having to perform left-right alignment.
Another object of the present invention is to provide a night cover hooking structure in which a hook of a night cover can be quickly hooked on a hook provided on a handrail molding, and the hooked state can be reliably maintained. To provide. An open showcase according to the present invention has a display room 1 having an open front surface.
A cold air outlet 6 is provided at the front of the upper wall, and a cool air suction port 8 and a handrail molding 16 made of a strip material are provided at the upper end of a weir portion 7 erected at the front of the bottom wall of the display room 1. It is provided adjacent inside and outside. In addition, automatic winding type night cover 11
Are arranged at the front of the outlet 6. Railing Mall 16

A hook rib 25 for hooking the hook 14 of the night cover 11 is provided below the inner end of the inner protrusion 21 so as to project toward the inlet panel 24. Specifically, the handle 13 is fixed to the drawn end of the night cover 11, and the handle 13
The hook 14 is provided at the lower part of. A recess 26 that allows the hook 14 to enter is provided along the hook rib 25 in front of the lower surface of the hook rib 25. The hook H that is in contact with the upper surface of the suction port panel 24 is set so that the distance H between the hook ribs 25 and the suction port panel 24 is opposite.
4 is set slightly larger than the hook height h. Further, the vertical height of the concave portion 26 is set to be larger than the facing distance H. When the night cover 11 is used, the film surface wound in a roll is pulled out and expanded, and the hook 14 provided at the lower end thereof is hooked on the hook rib 25 of the handrail molding 16. The hooking ribs 25 project along the longitudinal direction of the handrail molding 16 and project downward toward the suction panel 24, so that the hooking ribs 25 do not hinder the taking in and out of products and cleaning. In addition, the hook 14 can be hooked on the hook rib 25 without having to align the hook 14 in the left-right direction. Since the hook rib 25 projects downward from the lower portion of the inner end of the overhanging inner protrusion 21, the hook 14 can have a sufficient hook depth and the free end of the hook 14 can be hooked to the hook rib 25. The hook 14 can be easily hooked on the hook rib 25 simply by operating the lower end of the hook through the front. If the recess 26 is provided in front of the lower surface of the hook rib 25, the operation of hooking the hook 14 on the hook rib 25 as described above can be performed more reliably. With the front surface of the hook 14 or the handle 13 abutting on the inner protrusion 21,
This is because the hook 14 is pulled upward by releasing the hand from the handle 13 and is hooked on the locking rib 25 without any room for escape. Hook rib 25 and suction panel 2
4 is set to be slightly larger than the hook height h of the hook 14, the hook 14 is pulled toward the front side with the hook 14 being in contact with the suction port panel 24, so that the hook 14 The free end can be located in the recess 26,
The hooks 14 can be quickly hooked on the hooking ribs 25 without any need for vertical and front-back positioning. According to the present invention, the handrail molding 16 is provided with an overhanging inner projection 21, and the hooks of the night cover 11 are hooked to the locking ribs 25 projecting below the inner end of the inner projection 21. 14 so that it can be hooked, while preventing the hooking ribs 25 from getting in and out of the product and cleaning,
The hook 14 can be easily hooked on the hook rib 25. Compared to a cover hooking structure in which a hooking hole is provided in the inner wall of the railing molding 16, the hook 14 can be hooked easily without the necessity of performing left-right alignment, and a sash is used for the hooking portion. As compared with the cover hooking structure described above, the hooking depth of the hooking rib 25 and the hook 14 can be made sufficient, and the hooking state of the hook 14 can be reliably maintained.
Even if the night cover 11 is shaken by the wind,
The hook 14 does not come off the hook rib 25. A recess 26 that allows the hook 14 to enter in front of the lower surface of the locking rib 25.
Is provided, and an opposing interval H between the hooking rib 25 and the suction port panel 24 is provided.
Is slightly larger than the hook height h of the hook 14, the inner protrusion 21 and the suction panel 24
The hook 14 can be hooked on the hooking rib 25 by merely applying the hook 14 or the handle 13 to the guide body in order, so that there is no need to confirm the positions of the hook 14 and the hooking rib 25. The hook 14 can be easily and promptly latched and released. FIG. 1 to FIG. 4 show an embodiment of an open showcase according to the present invention. In FIG. 2, the open showcase has a display room 1 with an open front surface.
A cooling air circulation path 2 and a heat insulating wall 3 are provided so as to surround the bottom, back, and upper part of the apparatus. The heat exchanger 4 is arranged in the back room of the circulation path 2, and the blower fan 5 is arranged in the bottom room. In order to form an air curtain C at the opening on the front of the display room 1,
A cool air outlet 6 is provided in front of the upper wall of the display room 1. Further, a weir portion 7 is provided upright at the front of the bottom wall of the display room 1, and a cool air inlet 8 is provided at the upper end thereof. Outlet 6 and inlet 8
Are provided at two places before and after, respectively. Inside the display room 1, shelves 9 are provided in multiple stages. Reference numeral 10 denotes a mirror, and 11 denotes an automatic winding type night cover. The night cover 11 is arranged above the front part of the outlet 6, and the film surface is wound up in a roll shape when not in use. In order to pull out and expand the night cover 11, as shown in FIG. 3, a frame 12 is fixed to the lower end of the film surface, and a handle 13 is fixed to the center in the width direction. The handle 13 is made of a plastic molded product, and a hook 14 is integrally formed at a lower portion thereof. The handrail molding 1 is adjacent to the front of the suction port 8.
6 is arranged. The handrail molding 16 is made of a strip formed by pressing or rolling a metal plate such as an aluminum plate or a stainless steel plate, or a strip such as an aluminum mold, and has a front mounting portion 17, a first bent portion 18, and a rearward rising shape. The inclined portion 19, the second bent portion 20, the inner projection 21 and the inner mounting portion 22 are formed continuously. By fixing the front mounting portion 17 and the inner mounting portion 22 to the bracket 23 with screws, the second bent portion 20 is located at the upper end of the weir portion 7, and the inner protruding portion 21 is over the front portion of the suction port panel 24. Hang out. The bracket 23 is fixed to a frame inside the weir portion 7. In order to hook and fix the hook 14 of the night cover 11, a hooking rib 25 having a V-shaped cross section is protruded downward at the lower portion of the inner end of the inner protrusion 21, and is provided in front of the lower surface of the hooking rib 25. A recess 26 is formed to allow the hook 14 to enter. Recess 26
Are enclosed on three sides by the lower surface wall of the inner projection 21, the inner mounting portion 22, and the suction port panel 24, and open toward the display room 1. As shown in FIG. 4, the facing distance H between the hooking rib 25 and the suction port panel 24 is set slightly larger than the hook height h of the hook 14 in contact with the upper surface of the suction port panel 24, and The vertical height is set to be larger than the facing distance H. This is to make it difficult for the hook 14 to come off from the hooking rib 25 while facilitating the hooking operation of the hook 14 to the hooking rib 25. When the night cover 11 is extended to cover the front opening of the display room 1, the hook 14 is
Hook 25. Specifically, as shown in FIG. 4, the night cover 11 is pulled out until the lower portion of the hook 14 contacts the suction port panel 24, and in this state, the handle 13 is pulled toward the near side (the side shown by the imaginary line). Then, the hook 14 or the front surface of the handle 13 is brought into contact with the inner protrusion 21, and the hand is released from the handle 13. Since the core body at the upper end of the night cover 11 is always urged to rotate the film body in a roll-up direction, the night cover 11 is pulled upward at the same time when the hand is released from the handle 13, and as shown in FIG. The hook 14 is hooked on the hooking rib 25 as shown. In this hooking state, the hooking depth of the hook 14 and the hooking rib 25 is substantially equal to the protrusion dimension of the hooking rib 25, so that, for example, the night cover 11 may be swung by the wind. Also, the hook 14 does not come off the hooking rib 25, and the hooked state of the hook 14 can be reliably maintained. The cross-sectional shape of the hooking rib 25 can be changed to a U-shape, a semicircle, a square, or the like in addition to the V-shape. Anything that protrudes may be used. In particular, when the handrail molding is formed of an aluminum mold, a plate-like rib protruding downward can be used as the locking rib 25. Hook 1
4 can be formed separately from the handle 13, in this case the hook 1
4 can be flexibly connected to the handle 13.
