Japanese Unexamined Patent Publication No. 2012-85905

On the front side of such a shelf board 100, as shown in FIG. 7, a front side frame member 140 is attached on a bracket 120 by a rivet 170, and a flat plate 150 is placed on the front side frame member 140. It is placed. However, since the head 171 of the rivet 170 protrudes from the upper surface of the front frame member 140, the flat plate 150 is actually placed on the head 171. In order to prevent the head 171 from coming into contact with the flat plate 150, a spacer may be arranged between the front frame member 140 and the flat plate 150. The front frame member 140 is formed by stacking a first L-shaped member 141 and a second L-shaped member 142 having a substantially L-shaped side view on the top and bottom, and integrating them by spot welding at several places. Has been done. Note that 143 in FIG. 7 is a nugget generated by spot welding.

By spot welding, spot welding marks 144 are formed on the upper surface and the lower surface of the front frame member 140. The spot weld mark 144 is visible through the coating film even if it is painted. Therefore, in such a shelf plate 100, when a transparent glass plate is used as the flat plate 150, spot welding marks 144 on the upper surface of the front side frame member 140 can be seen through the glass plate, and the shelf plate 100 and eventually the show There was a problem that it spoiled the aesthetics of the case.

Further, the head 171 of the rivet 170 protrudes above the upper surface of the second L-shaped member 142. Therefore, a gap R is formed between the upper surface of the front frame member 140 and the lower surface of the flat plate 150 so that the head 171 of the rivet 170 is interposed. The same applies when the spacer is arranged. Dusts D may collect in this gap R. When a transparent glass plate is used as the flat plate 150, if dust D accumulates in the gap R, the appearance of the shelf plate 100 and the showcase is significantly impaired. In that case, a clerk needs to clean the shelf board 100. In stores such as convenience stores where labor saving is required, it has been an issue to solve the problem that dust D is accumulated in this gap R.

The present invention has been made in view of the above situation, and provides a frame member whose aesthetic appearance is not impaired even when a transparent glass plate is used as a flat plate for a showcase shelf. Make it an issue.

The present invention is a frame member that is hung over the front ends of a pair of left and right brackets, is formed by folding, and a structure for attaching the frame member to the bracket is provided in the folded region. The above problem is solved by providing a frame member in which the two ends in the hand direction stand up from the overlapping regions at intervals.

According to the present invention, it is possible to provide a frame member whose aesthetic appearance is not impaired even when a transparent glass plate is used as the flat plate of the shelf plate of the showcase.

It is a perspective view of the shelf board which concerns on this invention using the frame member which concerns on this invention. It is a right side view of one Example of the frame member which concerns on this invention. It is a bottom view of one Example of the frame member which concerns on this invention. It is a right side sectional view of the front side of the shelf board using the frame member which concerns on this invention. It is a bottom view of another Example of the frame member which concerns on this invention. It is a bottom view of still another Example of the frame member which concerns on this invention.

The detailed structure of the front frame member 4 and the mounting structure of the bracket 2 and the front frame member 4 will be described in detail later.

A flat plate 5 is placed on the back frame member 3 and the front frame member 4. The flat plate 5 is a transparent glass plate. By using a transparent material such as glass or acrylic as the material of the flat plate 5, the appearance of the showcase using the shelf board 1 and thus the shelf board 1 can be improved, but the flat plate 5 is not transparent. Needless to say that can be used.

(2) Structure of Front Frame Member 4 Next, the structure of the front frame member 4 will be described with reference to FIG. 2, which is a right side view of the front frame member 4. The front frame member 4 has a length in the left-right direction that can be hung between the pair of brackets 2, and is formed by folding one plate member such as a steel plate. The plate member forming the front frame member 4 is a plate made of a metal such as steel or a synthetic resin such as acrylic.

The folded region formed by folding one plate member is composed of a lower first flat plate portion 41 and an upper second flat plate portion 42. The first flat plate portion 41 has a lower surface 41B in contact with the upper surface of the bracket 2 (horizontal plate 22). The second flat plate portion 42 is superposed on the first flat plate portion 41, and is connected to the first flat plate portion 41 via the first bent portion 45 at the rear end of the front side frame member 4. The first bent portion 45 is a portion formed by bending the plate member 180 degrees.

The two ends of the front frame member 4 in the lateral direction stand up at intervals from each other, and the third flat plate portion 43 that stands up and extends from the front end of the first flat plate portion 41. It forms a fourth flat plate portion 44 that stands up and extends from the front end portion of the second flat plate portion 42. In other words, the first flat plate portion 41 and the third flat plate portion 43 are connected via the second bent portion 46, and the second flat plate portion 42 and the fourth flat plate portion 44 connect the third bent portion 47. Connected via. The second bent portion 46 and the third bent portion 47 are both portions formed by bending the plate member by 90 degrees.

A space S is formed between the third flat plate portion 43 and the fourth flat plate portion 44. This space S is used for attaching a price card, a price rail, or the like, as will be described later.

Through holes 48 are provided on both the left and right sides of the folded region composed of the first flat plate portion 41 and the second flat plate portion 42. The through hole 48 is formed by a continuation of a small diameter hole 49 provided in the first flat plate portion 41 and a large diameter hole 50 (corresponding to the enlarged diameter portion of the present invention) provided in the second flat plate portion 42. There is. The diameter of the small-diameter hole 49 is sized so that the shaft portion of the screw or rivet used when fixing the front frame member 4 to the bracket 2 can pass through, but the head portion of the screw or rivet does not pass through. The diameter of the large-diameter hole 50 is set to pass through the head of the screw or rivet. Further, the thickness of the second flat plate portion 42 (that is, the plate member constituting the front frame member 4) is equal to or larger than the thickness of the head of the screw or the rivet. Therefore, the head of the screw or the rivet can be placed in the large-diameter hole 50 without protruding above the upper surface of the second flat plate portion 42.

If the thickness of the head of the screw or rivet is sufficiently smaller than the thickness of the plate member constituting the front frame member 4, a part of the small diameter hole 49 is provided in the first flat plate portion 41. At the same time, the second flat plate portion 42 may be provided with the other portion of the small diameter hole 49 and the large diameter hole 50 continuously. Further, when the thickness of the head of the fixing member is larger than the thickness of the plate member constituting the front frame member 4, the small diameter hole 49 and a part of the large diameter hole 50 are continuous in the first flat plate portion 41. The second flat plate portion 42 may be provided with another portion of the large-diameter hole 50.

(3) Mounting Structure of Bracket and Front Frame Member As shown in FIGS. 2 and 3, these members are attached to the lower surface 41B of the first flat plate portion 41 when the front frame member 4 is mounted on the bracket 2. A positioning structure 6 for positioning is provided. In this embodiment, as the positioning structure 6, a rectangular parallelepiped protruding piece 61 and a regular square columnar protruding piece 62 are provided on each of the left and right sides of the lower surface 41B of the first flat plate portion 41.

These projecting pieces 61 and 62 are provided at positions where they can come into contact with the inner side surface 2I and the front surface 2F of the bracket 2 shown by the broken lines in FIG. 3, respectively. Therefore, the front frame member 4 can be easily and accurately positioned with respect to the bracket 2.

When the bracket 2 and the front frame member 4 are positioned, as shown in FIG. 4, the bracket hole 24 provided in the bracket 2 and the through hole 48 provided in the front frame member 4 overlap each other. It becomes a state. In this state, the bracket 2 and the front frame member 4 are fixed by the rivet 7. A screw such as a bolt may be used instead of the rivet 7.

At this time, the thickness of the head 71 of the rivet 7 is smaller than the thickness of the second flat plate portion 42. Therefore, the head 71 does not protrude from the upper surface 42U of the second flat plate portion 42. Therefore, the flat plate 5 can be placed on the second flat plate portion 42 so that a gap is not formed between the lower surface 5B of the flat plate 5 and the upper surface 42U of the second flat plate portion 42. Therefore, it is possible to prevent dust from accumulating between the lower surface 5B of the flat plate 5 and the upper surface 42U of the second flat plate portion 42, and it is possible to prevent the appearance of the shelf plate 1 and the showcase from being spoiled. Can be done.

Further, the front frame member 4 is formed by bending one plate member, and the first flat plate portion 41 and the second flat plate portion 42 are not fixed by spot welding. There are no spot welding marks on the upper surface 42U of the flat plate portion 42. Therefore, no spot welding marks can be seen on the upper surface 42U of the second flat plate portion 42 via the transparent flat plate 5, and the appearance of the shelf plate 1 and thus the showcase is improved.

In this embodiment, since the spacer 33 is provided on the upper surface of the back frame member 3 and the height of the back side of the flat plate 5 is adjusted, the lower surface of the flat plate 5 is relative to the upper surface 42U of the second flat plate portion 42. 5B can be brought into surface contact. If the difference between the thickness of the horizontal plate 31 of the back frame member 3 and the total thickness of the first flat plate portion 41 and the second flat plate portion 42 of the front side frame member 4 is small, even if the spacer 33 is not provided. The intersection angle between the upper surface 42U of the second flat plate portion 42 and the lower surface 5B of the flat plate 5 becomes smaller. That is, the gap formed between the upper surface 42U of the second flat plate portion 42 and the lower surface 5B of the flat plate 5 becomes smaller. In that case, the spacer 33 may not be provided because the risk of dust accumulation in the gap is reduced.

(4) Usage of the Shelf Board 1 The shelf board 1 described above is fixed to the showcase by inserting the engaging piece 23 (see FIG. 1) of the bracket 2 into the groove provided in the shelf support. To. The shelf board 1 is fixed in such a posture that the flat plate 5 is horizontal or the front side of the flat plate 5 is slightly lowered. Products such as food and drink are displayed on the shelf board 1 (flat plate 5) fixed to the showcase. Since the heights of the third flat plate portion 43 and the fourth flat plate portion 44 are relatively low, when the product display work is performed from the front side of the shelf board 1, the front side frame member 4 does not interfere with the work.

On the other hand, the height of the fourth flat plate portion 44 of the front side frame member 4 is a height capable of preventing the product placed on the shelf plate 1 from falling toward the front side. Therefore, the shelf board 1 can be displayed without the risk of dropping the product toward the front side without separately using a product fall prevention member made of a transparent acrylic plate having an L-shaped side view, for example. Further, since there is no such product fall prevention member, it is easy to display the product from the front side.

Further, such a product fall prevention member may collide with a hand or a product and be damaged when a store clerk displays the product or a customer takes out the product. In that case, the appearance of the showcase is significantly impaired. It has a problem of being lost. On the other hand, if the shelf board 1 is used, it is not necessary to use such a product fall prevention member in the first place, so that there is no problem of aesthetic loss of the showcase due to damage to the product fall prevention member. It is also possible to use the shelf board 1 and the above-mentioned product fall prevention member in combination depending on the weight and size of the product.

Further, in the shelf board 1, the third flat plate portion 43 and the fourth flat plate portion 44 of the front frame member 4 can function as price rails. That is, the price card or the like can be erected in the space S between the third flat plate portion 43 and the fourth flat plate portion 44, or can be hung from the third flat plate portion 43. It is also possible to separately prepare a price rail made of transparent resin or the like, hang it on the third flat plate portion, and attach it by hanging it. In either case, the fourth flat plate portion 44 is present between the price card or the price rail and the product displayed on the shelf board 1. Therefore, it is not necessary for these price cards and price rails to have a product fall prevention function, and their structures can be simplified. Further, the fourth flat plate portion 44 can prevent these price cards and price rails from colliding with the product and being damaged.
