Description

[Detailed description of the invention] This invention relates to a display frame device that is hung from structures such as station premises and building corridors for the purpose of displaying guide maps and promotional texts. It is designed so that a display board can be attached to it.

Guide maps and various promotional materials are posted on structures such as station premises and building corridors. These bulletin board devices come in various forms, each having a structure suitable for its purpose. However, in all conventional display frame devices, the parts constituting the display frame device have different shapes on the top, bottom, left and right, and cannot be manufactured using common parts. For this reason, the number of types of molds for manufacturing parts increases, which increases the number of manufacturing steps and increases costs.

This idea is to suspend from a structure a base frame in which an upper member and a lower member, each having a symmetrical cross-sectional shape in the front-to-back direction, are set horizontally above and below, and display boards are attached to both the front and back sides of the base frame. The present invention aims to provide a display frame device that is economical and has an excellent display function.

Next, an embodiment of this invention will be explained with reference to the drawings. In FIG. 1, 1 is a display frame device;
It is suspended from a structure 3 by a support plate 2. A display board 5 on which figures or characters are written is attached to a display frame 4 on the front surface of the display frame device 1, and is illuminated by a fluorescent lamp 6 provided inside. This display frame device 1 is
As will be explained next, the back side has exactly the same structure as the front side, and both sides are illuminated by the internal fluorescent lamp 6.

Fig. 2 shows the inside of Fig. 1, and shows Fig. 1 in a cross section along the - line, and the base frame 7 has a symmetrical cross-sectional shape in the front-back direction (left-right direction in Fig. 2). It is a frame-shaped member in which an upper member and a lower member are provided horizontally above and below, and both ends of the upper member and the lower member are connected by vertical side members (not shown). The upper member of this base frame 7 is suspended from the structure 3 by a support plate 2 attached by bolts 8. A reinforcing plate 9 is attached to the lower surface of the upper member with bolts 10 and nuts 11. Holes 12 and 13 are bored in the upper part of the reinforcing plate 9 and the base frame 7 at positions where they overlap, and a pipe 14 through which the power line of the fluorescent lamp 6 is inserted passes through the holes 12 and 13 to insert the washer 15. and is fixed with nut 16. 17 is a rock nut. Note that this pipe 14 is located behind the support plate 2 and is not visible from the outside.

On both sides of the front and back sides of the upper member of the base frame 7, a hinge member 19, which has a horizontally extending circular arc groove 18 and is made of a different material from the upper member of the base frame 7, is attached with screws 20. . And this hinge member 19
A cylindrical protrusion 21 provided horizontally on the upper back side of the display frame 4 is fitted into the horizontal arcuate groove 18 . Thereby, the display frame 4 is supported so as to be rotatable in the vertical direction indicated by the arrow in the figure. The display frame 4 can be removed from the upper member of the base frame 7 when the display frame 4 is opened at a certain angle, for example, 45 degrees or more. In addition,
A projection piece 22 is provided on the lower side of the cylindrical projection 21 of the display frame 4, and when the display frame 4 is closed, the base frame 7
It is arranged to come into contact with a buffer plate 23 attached to the upper member of.

The display frame 4 has the same outer dimensions in the upper, lower, left, and right directions as the base frame 7, and is manufactured into a frame shape that has the same outer shape as the base frame 7 when viewed from the front.
4 and 25 are adapted to grip the upper and lower parts of the display board 5. In this embodiment, the projecting piece 25 is a separate member attached by a bolt 26, but it may be formed integrally instead of this. The display board 5 may be made of a transparent synthetic resin board, and may be directly printed on or a poster may be pasted thereon. Note that the side portions of the display board 5 are supported by members that connect the upper and lower side portions of the display frame 4.

The lower part of the display frame 4 has a shape similar to that of the upper part, but is provided with a protrusion 28 that rotatably supports a set screw 27. The set screw 27 is prevented from falling out by a retaining member 29.
The set screw 27 is adapted to be screwed into a lock member 31 attached to the base frame 7 by a bolt 30. When the set screw 27 is screwed into the lock member 31,
The display frame 4 is engaged with the base frame 7 .

This display frame device 1 configured as described above is used in the following manner. That is, when using the guide map, advertisement, etc. displayed on the display board 5 without changing it for a long period of time, the length of the display board 5 in the vertical direction can be adjusted by adjusting the length of the display board 5 in the vertical direction by
The length between the grooves sandwiched between the display board 5 and
When installing, the bolt 26 can be loosened and the projecting piece 25 can be removed.
This is done by loosening the lock to release the lock and opening the display frame 4 in the upward direction indicated by the arrow.

When changing the display content relatively frequently, the length of the display board 5 in the vertical direction is slightly shorter than the length between the grooves between the upper and lower protrusions 24 and 25 of the display frame 4, as shown in FIG. If the display board 5 is thus made to be able to be removed by lifting it upward from the surface by hand and then pulling the lower part towards you, the work can be done without operating the set screws 27 for locking. Become. Note that when replacing the fluorescent lamp 6, etc., loosen the set screw 27 and then remove the display frame 4.
The display frame 4 can be removed from the base frame 7 by lifting it at an angle of about 45 degrees or more, making the work easier.

This idea consists of a base frame in which an upper member and a lower member, each having a symmetrical cross-sectional shape in the front-to-back direction, are installed horizontally above and below, is suspended from a structure, and a display frame that holds a display board is attached to the front and back sides of the base frame. , the display function can be improved by effectively using both sides of the base frame for display.

The outer shape of the display frame that holds the display board is the same as the base frame, so the base frame is not exposed on the outside of the front and back surfaces, and only the display frame appears, resulting in a display frame device with a clean feel. .

In addition, the display frame is supported by fitting the horizontal cylindrical projection of the display frame into the horizontal arc groove of the hinge member, so even if it is a large and long display frame, it can be supported over its entire length. This has the effect of preventing insufficient support strength.

Furthermore, since the lower part of the display frame is locked to the locking member with a set screw, the display frame will not come off the base frame due to earthquakes or other vibrations, and the locking state can be maintained reliably.
