Description

  The present invention relates to a night cover that covers an opening surface of a refrigerated showcase or the like when a store such as a supermarket is closed. In particular, the present invention relates to a night cover that can be easily and safely attached to an existing showcase.

  For showcases with open front or top surfaces for refrigeration or freezing provided in stores such as supermarkets and convenience stores, the opening surface is covered with a night cover when the store is closed, and the loss of heat from the product display space is lost. Is suppressed. In particular, in recent years, high-performance night covers using screens with improved thermal insulation have become widespread, so that existing night covers that are currently installed can be replaced, or new night covers can be adopted for showcases. Things have also increased.

  When the night cover is attached to the top plate of the showcase using screws, it is common to attach a dedicated mounting bracket to the night cover and fix the bracket to the top plate with screws. By the way, a fluorescent lamp for illumination is attached to the top plate of the showcase, and electric wires, a transformer, a controller and the like are accommodated on the back side of the top plate. For this reason, when opening the hole which attaches a metal fitting to a top plate, the situation which may damage these components or generate | occur | produce an electric leakage accident may also occur. Moreover, it takes time and effort to prepare a dedicated mounting bracket.

  Therefore, night covers that can be detachably attached to the showcase with magnets have been proposed (see, for example, Patent Documents 1 and 2). By making it detachable, it can be attached to an existing showcase that is not equipped with a night cover, and is stored below the front of the showcase when the night cover is not in use, such as during store opening. You can also The magnet is in the form of a flat plate, and is supposed to be attached to the lower surface of the top plate of the showcase in the width direction.

  However, as described above, a fluorescent lamp for product illumination is attached to the top plate of the showcase, and various parts for the fluorescent lamp are accommodated on the back side of the top plate. Projections such as a clip holder for bundling electric wires and a screw head for attaching components to the top plate are present on the lower surface of the top plate. Furthermore, the position of such a protrusion differs for each showcase. For this reason, when a flat plate-like magnet is attracted to the top plate, it is necessary to select a position where these protrusions are not present, but it is often impossible to attach it to a desired position.

  This invention is made | formed in view of said point, Comprising: It aims at providing the night cover which can be attached reliably and safely, even when a protrusion exists in a top plate.

The night cover of the present invention comprises a screen (10) covering the opening surface of the product display space (D) of the showcase (S), and the screen (10) so that the screen (10) can be pulled out. A set frame (30) attached to the plate (T), and a guide portion (35) extending in the width direction of the screen (10) on the upper surface of the set frame (30) facing the top plate (T). ) rail member is formed (31) is provided with a slide plate equipped with a magnet (53) for mounting said set frame (30) before Kiten plate (T) is (51), said set frame ( the guide portion in the longitudinal direction of 30) with is provided slidably along the (35), said slide plate (51), in engagement with the guide portion (35), the magnet (53 ) Is the rail Projecting from the upper surface of the member (31), a space is opened between the upper surface of the magnet (53) and the upper surface of the rail member (31) .
The method of attaching the night cover according to the present invention is as follows. When the night cover night cover (1) is attached to the showcase (S), a screw or wire is provided near both ends in the width direction of the top plate (T) of the showcase (S). A mounting location where there is no protrusion such as a grip is selected, and the slide plate (51) is slid along the rail member (31) so as to correspond to the selected mounting location.

  In the present invention, a guide portion extending in the longitudinal direction is formed on the surface of the set frame facing the showcase top plate, and the slide plate on which the magnet is mounted can slide along the guide portion. .

  In the present invention, since the magnet is attached to the top plate, it is not necessary to prepare a dedicated mounting bracket or to open a hole for mounting the bracket on the top plate, and the night cover can be easily mounted in a short time. In addition, since dust or the like is not generated when the product is attached and the product does not fall on the displayed product, the product can be attached even while the store is open. Further, when holes are formed in the showcase, internal wiring or the like is not damaged.

Moreover, since the magnet can be moved along the longitudinal direction of the set frame, it can be installed in a relatively narrow location. Therefore, it is only necessary to select a place where installation is possible and move the magnet relative to the set frame so as to correspond thereto. As described above, the installation location can be selected according to the situation of the top board, so that various types of showcases can be handled.
Further, if the slide plate can be slightly tilted in the front-rear direction in the guide portion, the slide plate can be in a posture that matches the tilt of the top plate, so that the magnet can be attracted more securely to the top plate.

  It is standard that there are a pair of left and right slide plates, and each is provided near both left and right ends of the set frame, but the number may be changed according to the width and length of the screen. In addition, it is standard to provide two disc-shaped magnets on one slide plate, but the number of magnets may be changed or a rectangular magnet may be used.

  In this invention, it is preferable that the level | step difference with the adsorption | suction surface to the top plate of the said magnet from the top plate opposing surface of the said set frame is 2 mm or more.

  The magnet itself is slid to the position of the top plate without projections and is attracted there. By providing a step between the magnet's attracting surface and the top surface of the set frame (top plate facing surface), the screw heads and protrusions fixed to the showcase top plate do not hit the top surface of the set frame. Can be. The step is preferably 3 mm or more, particularly 5 to 10 mm.

  In this invention, it is preferable to have a drop-off preventing wire for suspending the set frame from the showcase top plate.

  In this case, the night cover can be held so as not to drop off even if the magnet attracting force is reduced or an unintentional force is applied to the night cover. One end of the drop-off prevention wire can be fixed to the slide plate, and the other end can be fixed to an existing screw or the like existing on the top plate. Also in this case, there is no need to perform processing such as making a new hole in the top plate.

  As is clear from the above description, according to the present invention, the night cover is attached to the top plate with a magnet, so it is not necessary to prepare a dedicated mounting bracket or to open a hole for mounting the bracket on the top plate. Can be attached. Further, if the slide plate on which the magnet is mounted is slid along the width direction of the showcase, it can be installed in a relatively narrow location. Therefore, it is only necessary to select a place where installation is possible and move the magnet relative to the set frame so as to correspond thereto. As described above, the installation location can be selected according to the state of the top plate, so that it is possible to cope with a case where a projection is present on the top plate, and it is possible to deal with various types of showcases.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
With reference to FIG. 1, FIG. 2, the whole structure of the night cover which concerns on embodiment of this invention is demonstrated. FIG. 1A is a front view of the entire night cover, FIG. 1B is a side view, and FIG. 1C is a front view showing a mechanism in a set frame of the night cover. FIG. 2 is a side view showing a state in which the opening surface of the showcase is covered with a night cover.
As shown in FIG. 1, the night cover 1 includes a screen 10 and a set frame 30 that accommodates the screen 10 so that the screen 10 can be pulled out and is attached to a top plate of a showcase. As shown in FIG. 2, the night cover 1 is attached to a top plate T of a showcase S (front opening type). When the store is closed, the screen 10 is pulled out from the set frame 30, and the opening surface of the product display space D is covered with the screen 10.

  As shown in FIG. 1, the screen 10 is a rectangular sheet made of polyester, for example, and has a length and a width that match the opening surface of the showcase. The width is generally 3 to 4 (918 to 1223 cm), but if it is long (for example, 8 and 2446 cm), there is no gap between the two adjacent screens, resulting in heat loss. Reduced. The upper edge of the screen 10 is fixed to the roller 11. A stopback 13 is attached to the lower edge of the screen 10 along the width direction. A sheet-like magnet 15 is attached to the back surface of the stopback 13. A handle 17 is attached to the approximate center of the stopback 13. When covering the opening surface of the showcase, the screen 10 is pulled out from the set frame 30 with the handle 17 and the magnet 15 is attracted to the lower side of the opening surface of the showcase S (see FIG. 2).

  As shown in FIG. 1C, a spring brake set 21 is inserted into one end of the roll 11 to which the upper edge of the screen 10 is fixed. A stopper 23 is inserted into the other end of the roll 11 so as not to rotate with respect to the roll 11. As the spring brake set 21 and the stopper 23, those generally used for opening and closing a screen such as a night cover can be used.

  The set frame 30 includes a rail member 31 that is long in the width direction of the screen, a bracket 41 for fixing the spring brake set 21 and the stopper 23 to the rail member 31, and 2 for attaching the set frame 30 to the top plate of the showcase. A set of magnet assemblies 50.

The rail member will be described with reference to FIG.
The rail member 31 has substantially the same length as the width of the screen 10. As shown in FIG. 3 (B), the rail member 31 is a substantially U-shaped member whose cross-section is open at the top, and a bottom plate 31a that is long in the width direction and front and rear plates that rise from the front and rear edges of the bottom plate 31a. 31b. The bottom plate 31a has a thin convex cross-sectional shape, and a concave portion 33 through which a screw for fixing the bracket 41 is passed is formed continuously in the longitudinal direction at the center in the front-rear direction. Furthermore, opposing channel-shaped guide portions 35 are formed continuously in the longitudinal direction along the upper edge of the inner surface of the front and rear plates 31b.
The rail member 31 is an aluminum member that is generally manufactured by extrusion, and a screw fixing recess 33 is continuously formed in the longitudinal direction. Extrusion products are provided with rail members of various lengths.

  As shown in FIG. 1C, a spring brake set 21 inserted into the roll 11 is attached to one end portion of the rail member 31 by a bracket 41. At the other end of the rail member 31, a stopper 23 that is inserted so as not to rotate with respect to the roll 11 is attached by a bracket 41. Both brackets 41 are fixed to the recesses 33 with screws on both end surfaces of the rail member 31.

  As shown in FIG. 3, the magnet assembly 50 includes a slide plate 51 that is long in the longitudinal direction of the rail member 31, and two magnets 53 that are attached to the slide plate 51. The slide plate 51 slides in the longitudinal direction of the rail member 31 along the guide portion 35 with front and rear edges (a piece extending in the longitudinal direction) engaged with the channel-shaped guide portion 35 of the rail member 31. At this time, there is a slight gap between the slide plate 51 and the inner surface of the guide portion 35, and the slide plate 51 can be slightly inclined in the front-rear direction within the guide portion 35. For this reason, the slide plate 51 is inclined so as to match the inclination of the top plate T of the showcase S to which the night cover 1 is attached.

  The magnet 53 has a disk shape having a certain thickness (for example, about 8 mm), and the upper surface is a flat surface. The two magnets 53 are attached to the slide plate 51 with screws 57 along the longitudinal direction of the rail member 31 via washers 55. When the slide plate 51 to which the magnet 53 is attached is engaged with the guide portion 35 of the rail member 31, the entire magnet 53 protrudes from the upper surface of the rail member 31. In this example, the distance d between the upper surface of the magnet 53 and the upper surface of the rail member 31 is about 8 mm. The distance d is preferably 3 to 10 mm. That is, the surface of the night cover 1 that can be directly attached to the top plate is only the top surface of each magnet 53 of the two sets of magnet assemblies 50, so that a relatively narrow surface on which the protrusions of the top plate T do not exist is used. Can do. Then, in a state where the magnet 53 is attracted to the top plate T, an interval d of about 8 mm is opened between the upper surface of the rail member 31 and the top plate T, so that a protrusion exists between the intervals d. It will be.

  In this example, the magnet 53 is a neodymium type cap magnet having a diameter of 32 mm, an inner diameter of 5.5 mm, a height of 8 mm, and an attractive force of 25 kgf. A cap magnet is a combination of a magnet and a yoke (iron), and the attractive force is increased by concentrating the magnetic force on one side.

  One end of the drop-off preventing wire 60 is fixed to one end of the slide plate 51. The drop-off prevention wire 60 is obtained by crimping a round terminal 61 to both ends of a wire having a length of about 10 cm. One terminal 61 is fixed to the slide plate 51 with a screw 63. When the screw 63 is tightened, the tip of the screw 63 comes into contact with the upper surface of the bottom plate of the rail member 31, whereby the slide plate 51 can be temporarily fixed to the rail member 31. The other terminal 61 of the wire 60 is fixed to a screw or the like originally present on the top plate T when the night cover 1 is attached to the top plate T of the showcase S.

An example of a method for attaching the night cover 1 will be described with reference to FIG.
First, the state of the top plate T of the showcase S is confirmed, and an installation location is selected near both ends in the width direction of the top plate. In this example, the fluorescent lamp F is already attached to the top plate T. A symbol H in the figure is a handle of the night cover 1. Further, the top plate T has protrusions such as screws and wire grips. Since the portion of the night cover 1 of the present invention that is directly attached to the top plate T is only the upper surface of each magnet 53 of the two sets of magnet assemblies 50, it is a relatively narrow surface without protrusions and in the vicinity thereof. Select two locations where existing screws are attached. Then, each magnet assembly 50 is slid along the rail member 31 so as to correspond to the selected portion. Next, a screw 63 for fixing the drop prevention wire 60 of each magnet assembly 50 is tightened, and each magnet assembly 50 is locked so as not to move with respect to the rail member 31.

  In this state, each magnet assembly 50 is positioned at the selected mounting location, and the magnet 53 is attracted. Finally, the terminal 61 at the free end of the drop-off prevention wire 60 is fixed to the existing screw B.

  In this way, the existing showcase can be easily attached without processing or using a special tool. Moreover, since no dust or the like is generated at the time of installation, the dust does not fall on the product. Therefore, it can be attached in a short time even while the store is open. Furthermore, when the attracting force of the magnet 53 of the magnet assembly 50 becomes weak or when an unintentional force is applied to the night cover 1, the night cover 1 is fixed to the top plate by the drop-off preventing wire 60. The night cover 1 can be prevented from falling.

  In this example, two sets of magnet assemblies 50 are provided near both ends of the rail member 31 in the width direction, but the number may be changed according to the width and length of the screen. The magnet assembly 50 is typically provided with two disk-shaped magnets 53 on one slide plate 31, but the number of magnets may be changed or a rectangular magnet may be used.

  When attaching a plurality of night covers side by side, as shown in FIG. 5, if the ends of the set frames 30 are attached close to each other, the gap between the screens 10 of the adjacent night covers 1 can be reduced. The loss of cold can be prevented as much as possible.
