Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a bulletin board installed in station premises, underground passages, buildings, exhibition halls, etc. and used for display and decoration, and more specifically relates to a bulletin board used in a manufacturing factory or a bulletin board. The present invention relates to a parting surface structure in which a part of the parting part is replaced according to the posted item in a factory where the container is installed, and the parting part suitable for the posted item can be adjusted.

(Prior Art) For example, there is an electric display device proposed by the applicant, disclosed in Japanese Patent Application No. 2-59730. (Refer to Fig. 14) The configuration of this device is that a parting surface part forming the front side of the peripheral frame is formed in a removable manner L7 to the container frame, and as the bulletin board is replaced, it can be adjusted according to the bulletin board. The parting surface portions each having a suitable parting surface width can be replaced.

(Problems to be Solved by the Invention) By the way, in the conventional device described above, the parting surface portion forms the entire front surface of the container frame, so when replacing the bulletin board, for example, it is difficult to install the The bulletin board to be replaced and the width of the cutout surface appropriate for the bulletin board are brought to the site and replaced.

Therefore, the larger the bulletin board, the larger the parting surface and the heavier it must be transported, and the larger and heavier the parting surface, the more difficult it is to replace it. It turns out.

In addition, since it is necessary to prepare the parting surface portions with various widths of the parting surface, there is also a problem from the production side.

Furthermore, depending on the location where the bulletin board is installed, even if it becomes necessary to delicately adjust the width of the cutout surface in relation to the surroundings, such fine adjustment may not be possible.

Also, from the point of view of effective use of materials, a configuration in which the entire parting surface portion is replaced is wasteful and disadvantageous.

The present invention was developed taking these circumstances into consideration.
We have created a useful parting surface structure for a bulletin board that is easy to transport and replace, is advantageous in terms of production and effective use of materials, and allows fine adjustment of the parting surface width at the installation site. It is on offer.

(Means for Solving the Problems) In the parting surface structure of the bulletin board of the present invention, a fitting groove is provided around the inner peripheral edge of the parting surface main body forming the front surface of the container frame, and the fitting groove is provided with appropriate partings. It is characterized by having a structure in which the second parting surface portion of the surface width is detachable.

(Function) By attaching the second parting surface part of an appropriate parting surface width to the fitting groove on the inner peripheral edge of the parting surface part main body forming the front surface of the formwork, a parting part with a desired parting surface width can be freely formed. be.

Thereby, when replacing the bulletin board, the parting surface can be adjusted by simply replacing or attaching only the second parting surface part while leaving the parting part main body as it is.

(Example) An example of implementation of the present invention will be described in detail below with reference to the drawings.

The insertion portions 11, 11 are respectively inserted into the fitting portions 5, 5 of the ends of two adjacent edge rods 2, thereby connecting the edge rods 2 at a 90 degree angle. As a result, the cut surface of each end of each edge rod 2 only needs to be cut at right angles to its longitudinal direction. The parts II and 11 are fixed in the fitting parts 5 and 5 with screws (not shown) to prevent them from being removed.

The bearing part 4 on the outer periphery of the container frame 1 has a parting surface main body 1, respectively.
The two base end shaft portions I3 are pivotally connected, and the parting surface main body I2 is swingable between a parting state and a not parting state.

The parting surface main body 12 is made of extruded synthetic resin or aluminum, and its cross-sectional shape consists of a detail 13 on the outer back side, a horizontal part 14 on the front side of this shaft part 13, and a horizontal part 14 in front of the horizontal part 14. Parting piece portion 1 extending inward from the edge, with the inner edge reaching further inside the horizontal portion of the edge rod 2

The fitting groove 16 on the inner edge of the parting piece portion 15 is provided with a second parting surface part 17 having an appropriate parting part width and a corner cut at an angle of 45 degrees, which is removably glued.

The second parting surface portion 17 is formed by cutting an extruded second parting surface material 18 made of synthetic resin or aluminum into an appropriate parting surface width.

The cross-sectional shape of the second parting surface material 18 is the fitting groove ■6.
On both sides of the plate portion 19, which has the same thickness as the groove width, a stepped edge 20 is formed on one side, and a stepped edge 21 is formed on the other side, which is preferable in terms of design. It is possible to select the parting end edge side of the sheet and cut it to a desired parting surface width.

The second parting surface portion 17 is attached and detached with the parting surface main body 12 attached to the container frame 1 or removed from the container frame 1. For the latter reason, the shaft portion 13 of the parting surface main body 12 has a substantially semicircular cross section with a narrow surface portion 13g having a diameter smaller than the width of the opening 4a formed on the inner side of the narrow surface. In the state where it is swung to the non-partition state, the small diameter narrow surface portion 13a is connected to the opening 4a.
The parting surface main body 12 is detachably attached to the bearing part 4 so as to face the bearing part 4.

In addition, between the adjacent parting edge parts 20 and 20, there is a connecting piece 2 having an oval shape and extending over the concave groove 22 on the back side of the parting edge part 20.
3 are removably fitted together, so that the connection portion between the 20° and 20° parting edges is flush with no difference in level.

In addition, a magnetic material 24 such as an iron plate is placed on the back side of the parting piece portion 15.
The magnetic body 24 is attracted to the magnet 25 disposed on the side of the horizontal portion 6 facing the magnetic body, so that the parting surface main body 12 and the second parting surface part 17 are in a parting state. is temporarily locked.

The magnet 25 is attached with screws 26 at several locations along the horizontal portion 6, and the attachment can be moved back and forth and swing freely in the space S, even if there is a slight error in the positional relationship between the magnet 25 and the magnetic body 24. , all the magnets 25 are attracted to the magnetic body 24, so that a good temporary locking state can be obtained.

Further, a bulletin board 30 is stretched through a coil spring 29 to the hook portion 28 of each hook plate 27 arranged at several locations along the horizontal portion 6. The film-like bulletin board 30 is stretched or replaced by swinging the parting surface main body 12 and the second parting surface part 17 to a non-parting state, or by removing them from the container frame 1.

Further, a back plate 31 is attached to the back side of the container frame 1 with screws or the like, with its peripheral edge fitted into the stepped portion 8.

As a result, depending on the degree of separation of the film-like bulletin board 30, it is possible to freely change and adjust the attachment to the second parting surface portion 17 having the optimum width.
The second parting surface portion 17 can be opened and closed together with the parting surface main body 12, or it can be removed from the container frame 1 and the film-like bulletin board 30 can be replaced from the front side of the container frame 1.
