Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a card case for preventing card loss in a card-based bulletin board.

(Prior Art) Over the past few years, calls for exchange of unnecessary items, club activities, etc. have become popular, as can be seen in the personal information sections of newspapers and magazines. A card-based bulletin board is used as a means of announcing information called minicomi, but since the conventional bulletin board was structured so that the cards could be freely pulled out, the cards could be used for mischief or to monopolize information. Not only was there a problem that the cards were stolen, but there was also a problem that the bulletin board was being misused for purposes other than its original purpose due to the unauthorized replacement of cards.

Therefore, the applicant devised a "card case for preventing loss on bulletin boards" (Utility Model Application No. 57-205177) to prevent cards from being removed.
The application was filed first.

This loss prevention card case is a bulletin board in which a message card is housed in a number of card cases whose top plates are made of a transparent plate so that they can be replaced from the top opening. The message card is formed to be longer than the vertical width of the message card so that when the message card is stored in the card case, the upper end of the message card does not protrude upward from the card case, and the internal interval of the card case is narrowed. The card case is formed so that a finger cannot be inserted through the upper end opening, and an opening is formed in the bottom surface of the card case for inserting a push-up piece for taking out the card.

Therefore, with this loss prevention card case, it is difficult to remove the card from the top opening.
This makes it almost impossible to remove the card without permission.

(Problem to be solved by the invention) However, in the case of the loss prevention card case of the earlier application, the opening for inserting and removing cards is provided on the top side of the card case as in the past. There is a problem in that many people try to forcefully remove the card by inserting a wire or the like through this opening, which causes severe damage to the card case.

Furthermore, since the top side of the card case is open, there is a problem in that if the card case is installed outdoors, measures against rainwater, such as installing a separate roof or door, are required.

(Means for solving the problems) The present invention was made with the aim of solving the above-mentioned problems, and in order to achieve this purpose, the present invention adopts a method in which the surface plate is formed of a transparent plate. In a bulletin board in which a number of card cases are provided on a common board, and a message card with a bent bottom part is accommodated in the card case in a replaceable manner, an opening for inserting and removing the message card is provided in the card case. A locking edge is formed on the bottom surface and protrudes from the inner surface of the opening edge on the surface plate side of the opening to prevent the message card from falling out, with at least a small portion left open at both left and right ends of the opening. A message card circulation gap is formed between the locking edge and the substrate, and a guide slope is formed on the inner surface of the tip of the locking edge to guide removal of the message card.

(Function) Therefore, in the loss prevention card case for bulletin boards of the present invention, as described above, by forming the opening for inserting and removing the message card in the bottom of the card case, the existence of the opening can be detected. This makes it possible to prevent the message card from being lost due to removal or from misuse of the bulletin board by replacing the message card, and since the opening is not discovered, it is possible to prevent damage to the card case due to mischief.

In addition, a locking edge is provided on the inner surface of the opening edge on the surface plate side of the opening to prevent the message card from falling out, and a gap is formed between the locking edge and the base plate to allow the message card to flow. , the message card can be inserted into the card case through this circulation gap, and
Once inserted into the card case, the lower edge of the message card is locked on the locking edge to prevent it from falling, so that the stored state within the card case can be maintained reliably.

In addition, the locking edge is provided with a small opening left at both left and right ends of the opening, and a guide slope is formed on the inner surface of the tip of the locking edge to guide the removal of the message card. By inserting a thin wire-like tool into the upper surface of the message card inside the card case through the side opening and pulling it out while pressing it against the board, the message card is released from being locked to the locking edge. At the same time,
The message card can be easily removed from the circulation gap by being guided by the guide slope of the locking edge.

In addition, since only the bottom side is open, there is no risk of rainwater etc. entering the card case, and therefore it can be installed outdoors as it is without having to take measures against rainwater such as a roof.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the embodiment will be explained.

The bulletin board A of this embodiment is composed of a board 1 and a card case 2, as shown in FIGS. 1 to 4.

The board 1 constitutes the main body of the bulletin board A, and is made of a colored acrylic board.
A reinforcing frame 10 is attached to its outer peripheral edge.

The card cases 2 are arranged in multiple rows on the front side of the board 1, and include left and right side wall members 2.
0, 20, an upper wall member 21, a surface plate 22, a locking edge 23, and a blind plate 24.

The left and right side wall members 20, 20 and the upper member 21 are
Each of them is made of a transparent acrylic material and formed into a 3 mm square rod shape, and is glued to the front side of the substrate 1 in a gate shape.

The surface plate 22 is formed of a transparent acrylic plate, and is bonded to the upper surfaces of the left and right side wall members 20, 20 and the upper side wall member 21, which are formed into a gate shape as described above. As a result, a card case 2 is formed, which has an accommodation space a equal to the thickness of each side wall member (3 mm) and has an opening 25 on the bottom side.

The locking edge 23 is formed of a transparent acrylic material in the shape of a triangular bar with a height of 2 mm, and its bottom side is connected to the surface plate 22 that constitutes the opening edge on the side of the surface plate 22 of the opening 25.
By adhering to the inner surface of the lower edge of the locking edge 2
3 and the board 1 is a message card circulation gap 25.
The opening 25 is closed with a portion a (1 mm) left and a little opening portions 25b, 25b at both left and right ends of the opening 25 left, and the inner surface of the tip of the locking edge 23 has a hole for removing the message card. A guide slope 23a for guiding is formed, and a guide slope 23b for guiding insertion of the message card is formed on the outer surface side of the tip.

The blinding plate 24 is used to hide the location of the opening 25, and is therefore attached along the outer surface of the lower edge of the surface plate 22 where the opening 25 is provided, but in this embodiment, camouflage is used. In this sense, it is also attached to the outer surface of the upper edge of the top plate.

Further, the blind plate 24 must be made of an opaque material, and in this embodiment, a colored opaque acrylic material having the same color as the substrate 1 is used.

FIG. 5 shows an example of a message card C that is replaceably housed in the card case 2. There is a name column 5, a serial number column 6, and a secretariat approval stamp column 7. still,
In the title column 3, "I will give you", "I will give you",
Titles such as "Please exchange", "Please tell me", "Friend circle", "Alumni meeting", etc. are displayed, and the specific content is entered in the content column 4.

Next, the operation of the embodiment will be explained.

(B) Inserting the message card First, in order to store the message card C in the storage space a of the card case 2, insert the message card C through the circulation gap 25a provided on the bottom side of the card case 2, and insert the message card C by hand. By pushing the lower edge of the message card C, which cannot be pushed in, using a slightly thicker sheet material such as a business card, the message card C can be completely accommodated in the storage space a of the card case 2. Since the lower edge of the message card C is locked by the locking edge 23, the message card C is prevented from falling.

In this case, if the lower part of the message card C is deformed by bending upward before being inserted, the locking on the locking edge 23 becomes more reliable.

(b) Removing the message card Next, to remove the message card C stored in the storage space a of the card case 2, a tool B as shown in FIG. 6 is used.

This tool B has a thin wire-like insertion part 81 at the tip of a handle 80, and a protrusion 82 at the tip of the insertion part 81 that is large enough not to damage the message card C.
is formed. Therefore, the insertion part 8 of this tool B
