Description

  The present invention relates to an open showcase equipped with a night cover.

As is well known, an open showcase that is installed and used in a store such as a supermarket is equipped with an automatic wind-up night cover on the top front of the main unit case as an energy-saving measure. The night cover is pulled down to cover the tax face opening of the case body, so that outside air heat is prevented from entering the interior (see, for example, Patent Document 1).
Next, the structure of the open showcase equipped with the night cover and the conventional night cover latch structure are shown in FIGS. First, in FIG. 3, reference numeral 1 denotes an outer box of a case main body that becomes a heat-insulating housing with an open front, 2 denotes an inner box, 3 denotes a cold air circulation passage that surrounds the inner box 2 and is defined between the outer box 1, 4 is a cooler (evaporator of the refrigerator), 5 is an internal fan, 6 is a circulating cold air outlet, 7 is a circulating cold air suction grille disposed inside the front wall 1a of the outer box 1, and 8 is an internal chamber The product display shelf, 9 is a deck pan at the bottom of the cabinet, 10 is a canopy provided at the top of the front of the outer box 1, and 11 is a front mounted along the upper edge of the suction grill 7 and the front wall 1a. A cap (extruded product of resin), 12 is a self-winding night cover installed on the ceiling of the canopy unit 10 (the night cover wound around the core is spring-biased in the unwinding direction), 13 Is a latch attached to the tip of the night cover 12.

Further, as shown in FIGS. 4 (a) and 4 (b), the latch 13 has a hook-shaped hook 13a formed by bending its tip into a J-shape, and a handle having a hole 13b for placing a hand in the center. The structure is fastened to the front end frame portion 12a of the night cover 12 with screws 13c.
In the above configuration, when the night cover 12 is pulled out from the winding portion as shown in FIG. 5 so as to cover the front opening of the main body case, the hook of the latch 13 is connected to the front cap corresponding to the portion A in FIG. 11, the night cover 12 is hooked and held at this position by being hooked on an engaging portion 11a formed on the rear edge (inside of the cabinet).
Japanese Patent Laid-Open No. 2003-111651 (FIGS. 1 and 4)

By the way, as for the latch 13 of the night cover 12, the latch having the conventional structure shown in FIG. 4 has the following drawbacks in terms of function and usability.
That is, there is no particular problem when the latch 13 is latched to the rear edge of the front cap 11 at the drawing position of the night cover 12 as shown in FIG. 5, but the front fence 14 made of glass or acrylic resin is used as shown in FIG. In a showcase that is fitted on the front wall 1a of the case body by being fitted into a longitudinal groove formed in the front cap 11 (if the model does not have a front fence 14t, the groove is covered with a blind cover). When the night cover 12 is applied and hooked at the pull-out position, there is a display product in the fence 14 or in the warehouse (the product may protrude inside the fence 14 depending on how the product is displayed). If it remains in the way, it is difficult to hook the latch 13 on the side edge inside the front cap 11.

Therefore, in the prior art, as shown in FIG. 6, a night cover attached to the front end frame portion 12a of the night cover 12 is turned over so that the hook of the latch 13 is turned to the rear, and the night cover 12 is pulled down to be hooked in the lowered position. , The night cover 12 is pulled out to the front side of the fence 14, and the hook of the latch 13 is hooked on the front edge (outside of the cabinet) of the front cap 11.
That is, for each model with no front fence and with a front fence, conventionally, it is necessary to prepare two types of night covers 12 with different attachment directions of the latch 13 or to reverse the latch and replace it. Further, in the conventional structure, since the handle portion of the latch 13 is directly fixed to the front end frame portion 12a of the night cover, the night cover 12 grasped by the handle portion of the latch 13 and pulled down to the front of the fence 14 as shown in FIG. In order to hook the front cap 11 on the front cap 11, the front frame portion 12a of the long night cover together with the latch 13 must be tilted rearward and hooked on the front edge of the front cap 11, which is inconvenient.

  The present invention has been made in view of the above points, and the night cover equipped in the open showcase can be shared with each model of a fenceless or showcase with a fence, and also considers convenience when using the night cover. It is an object of the present invention to provide an improved open showcase so that the latching operation of the latch on the front cap can be performed easily.

  In order to achieve the above object, according to the present invention, an automatic wind-up night cover is provided on the front upper part of a front open case body, and the night cover is extended to cover the front opening of the case body. In the cold air circulation open showcase, a latch with a handle is attached to the end frame of the night cover, and the latch is hooked on the front cap laid on the upper edge of the lower front wall of the case body to lower the night cover to the position. The latch is provided with a bifurcated hook with hooks protruding on the front and back sides at the front end of the handle portion of the latch, and the handle portion of the latch is attached to the front end frame portion of the night cover. It is pivotally supported in the front-rear direction and corresponds to the structure of the latch provided with a bifurcated hook. The front cover can be easily pulled out and hooked by forming an engaging part that hooks a bifurcated hook provided at the end of the handle of the night cover latch on both side edges of the outside. None, so that it can be shared with each model with a front fence.

According to the above configuration, the night cover provided with a latch with a bifurcated hook is used as a shared part, and a hook that protrudes to the handle side of the latch is formed on the rear edge side of the front cap in a showcase without a front fence. In a showcase with a front fence, a hook protruding on the back side of the handle portion of the latch can be hooked on an engaging portion formed on the front edge side of the front cap, and the night cover can be pulled down and held at the position.
In addition, the handle part of the latch is pivotally supported with respect to the front end frame part of the night cover so as to be pivotable in the front-rear direction, so that the night cover can be pulled down and the front cap can be latched on the showcase model. It can be done easily regardless of the user-friendliness.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on the examples shown in FIGS. In addition, in the figure of an Example, the same code | symbol is attached | subjected to the member corresponding to FIGS. 4-6, and the description is abbreviate | omitted.
