DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a picture frame-like bulletin board for displaying a notice such as a poster.

[0002]

2. Description of the Related Art Generally, a bulletin board is designed to stop a poster with a thumbtack or an adhesive tape, but in this case, it is very troublesome to stop and pull the thumbtack, or to attach and remove an adhesive tape. In addition, since the appearance is not good, a frame-like bulletin board in which a poster is placed in a back plate and a transparent plate is sometimes used.

[0003] A frame-like bulletin board is basically a frame in which a back plate and a transparent plate are housed in a frame of a vertical and horizontal frame, like a general frame. Since the poster needs to be replaced while it is still installed, some measures have been taken to remove the transparent plate to the front in that state.

[0004] As the means, there can be first mentioned a means in which a frame can be opened and closed. In other words, according to this, at least a pair of frames are opened and closed by a hinge in order to remove the transparent plate holding the poster, but it is necessary to maintain the closed state of stopping the transparent plate. For this reason, the structure is complicated and the cost is high. In addition, replacing the poster involves a troublesome operation of attaching and detaching the transparent plate, and there is a problem that it is not easy to put the poster, especially if the poster is wide.

As another means, a cover frame to which a transparent plate is fixed is fixed to a base frame to which a back plate is fixed by a hinge or the like so as to be opened and closed like a door. However, in order to store a large poster, the operation is difficult, and when the poster is placed facing the passage, there is a problem that the opening causes an obstacle to the passage.

[0006]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention has a simple structure,
An object of the present invention is to provide a picture frame-like bulletin board that can easily and conveniently put a poster.

[0007]

In order to achieve the above object, the present invention provides a combination of a back plate holding frame as a substrate and a plurality of transparent plate holding frames covering the front surface thereof with at least two right and left sheets. The frame is divided into frames so that the transparent plate holding frame looks like a single transparent plate by abutting, and each transparent plate holding frame can slide on the back plate holding frame by engagement of the frames at the upper and lower ends. It is configured so that a notice such as a poster can be inserted into the gap between the back plate and the transparent plate from the opening of the transparent plate holding frame by the slide,
A frame-like bulletin board is provided in which a slide guide for receiving a notice is provided in a lower frame of a back plate holding frame.

According to the above arrangement, when replacing a notice, the notice is slid to open the space between the adjacent transparent plate holding frames, and the notice is inserted from the opening into the gap between the back plate and the transparent plate. By moving along the slide guide to place it in a predetermined location, and then closing the transparent plate holding frame, it appears that the notice is contained in one transparent plate.

In addition, each transparent plate holding frame is engaged with the back plate holding frame by a suspension type which can be disengaged by the load due to the load, and the transparent plate holding frame abuts the back plate holding frame. When the upper movement preventing member is attached to the lower frame so as to be able to release the prevention, when the inside is cleaned, the transparent plate holding frame can be removed by a simple operation of once lifting the transparent plate holding frame.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, when viewed from the front, it looks like a single picture frame. The holding frames 2 and 2 have a U-shape, that is, upper and lower frames 23 and
24 and a vertical frame 25. Further, when divided into three or more, the intermediate transparent plate holding frame 2a has frames 23 and 24 only on the upper and lower sides.

The back plate holding frame 1 is also required to be easily transported to the site, especially when the frame is long horizontally.
Sometimes it is divided into several parts and assembled on site at the same time. Further, in the back plate holding frame 1, the upper and lower frames 8, 9 are used as guide rails, and if they are provided, the upper and lower frames 8, 9 do not necessarily have to be framed. In addition, a guide block, a car, or the like may be specially attached to the transparent plate holding frame 2 (2a) to make the slide smooth. Further, it is desirable to provide a lock device such as a key and a stopper in order to maintain the closed state.

[0012]

As described above, according to the picture frame-like bulletin board of the present invention, unlike the case where the frame has an opening / closing structure in cross section, the structure is very simple and suitable for inexpensive provision. Moreover, the replacement of the notice does not require removal of the transparent plate, and furthermore, since the notice is easily inserted, there is an excellent effect that the workability of the replacement is improved. Further, if the transparent plate holding frame is engaged with the back plate holding frame by a suspension type (claim 2), the transparent plate holding frame can be easily removed, which is convenient for cleaning and the like. Furthermore, since each holding frame is appropriately divided and can be freely connected and added, there is an advantage that the holding frame can be appropriately set according to the wall space.

[0013]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 to 4 show an embodiment. The frame-like bulletin board is composed of a combination of a back plate holding frame 1 and a pair of left and right transparent plate holding frames 2 and 2. The poster 7 is inserted into the gap 4 between the back plate 3 and the transparent plate 5 by opening between the transparent plate holding frames 2 and 2.

The back plate holding frame 1 is such that a long back plate 3 is placed in the frame between the upper and lower frames 8, 9 and the left and right vertical frames 10, 10 and is fixed by screws 12, and a vertical A reinforcing member (reinforced square pipe) 14 is provided.
