Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to bulletin boards installed in station premises, underground passages, buildings, exhibition halls, etc. and used for display and decoration. The present invention relates to a device that can quickly and easily suspend a bulletin board, which is a flexible thin material in the form of a sheet or a sheet, in a tensioned state without slack.

(Prior art) For example, the inventor of the present application devised the
There is a bulletin board numbered 25113. (See Fig. 11) The structure of this bulletin board is such that a pair of front and rear latching receivers 51 are formed inside a container frame 50, and a hook plate 52 of this latching receiver 51 is removably latched. A large number of hanging hooks 53 are appropriately arranged and formed on the surface, and a spring 55 on which a bulletin board 54 is suspended is hung from the hanging hooks 53.

Even if each bulletin board 54 has a different number and position of hanging holes 56 for hooking the spring 55,
By hanging the spring 55 on a nearby hanging hook 53, the body can be suspended in a balanced state at all times. or,
When replacing the bulletin board 54, it is possible to easily replace the hook plate 52 itself, on which the spring 55 is hung from the front side of the container frame 50, by opening the parting piece 57.

(Problems to be Solved by the Invention) By the way, in the above-described structure of the bulletin board, the hook plate's hook receiver is located so as to be hidden behind the hook that supports the parting piece so that it can be opened and closed. Therefore, the work of attaching and detaching the hook plate is performed by groping for the latch receiving part which is hidden behind the latch part and cannot be seen, resulting in poor work efficiency.

In addition, since the latching receiver has a pair of front and rear configurations,
The container frame is necessarily thick and heavy, and as a result, there is a problem in that it is not possible to reduce the thickness and weight of the container frame.

The present invention was developed taking these circumstances into consideration, and allows for quick and easy installation work, including replacing the bulletin board while directly observing it, while also making it possible to make the frame thinner and lighter. The present invention provides a suspension device for a bulletin board in a bulletin board.

(Means for Solving the Problems) In the suspension device for a bulletin board in a bulletin board of the present invention, in a bulletin board formed by forming a partition on the front side of the container frame so that it can be opened and closed, the display is hidden by the partition in the container frame. Insert an appropriate number of retaining plates along the rear horizontal mounting part, and insert the insertion part of the rear edge of the retaining plate into the horizontal fitting groove on the inside of the rear end of the horizontal mounting part on the front side. Insert it through the opening, and fold the locking flange on the front edge of the same plate outward from the front edge of the horizontal mounting part.
It is characterized by a structure in which the bulletin boards are attached at approximately equal intervals and connected to the hooks on the inside of each hook plate via coil springs and suspended tensionally within the container frame.

(Function) Open the parting part, insert the hanging plate into the horizontal mounting part exposed on the front, first insert the insertion part on the rear edge of the hanging plate into the fitting groove, then insert the hanging flange into the horizontal position. It can be attached by folding it back to the outside of the attachment part, and can be freely removed from the horizontal attachment part by pulling out the hanging plate in this attached state towards you.

As a result, the mounting and replacement of the bulletin board can be done while opening the parting part and viewing the horizontal installation part with no obstructions.

Further, since the front and back width of the horizontal mounting portion may be approximately the same as that of the hanging plate, the container frame can be made thinner and lighter.

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