Description

[Detailed Description of the Invention] The present invention relates to an illuminated signboard having a translucent signboard surface with built-in lighting equipment such as fluorescent lights, and more specifically, the invention relates to an illuminated signboard having a transparent signboard surface with built-in lighting equipment such as fluorescent lights, and more specifically, to facilitate the replacement of lighting equipment on advertising signboards. It is related to the device.

Traditionally, advertising signboards with built-in lighting have had fluorescent lamp sockets and parts fixed to the frame inside the main body of the signboard with screws and wired, or once ballasts, glow bulbs, and fluorescent lamp sockets were attached to the fluorescent lamp holder. After the set is installed, wiring is generally done by locking the set inside the sign body.

However, the lifespan of fluorescent lights and glow bulbs is determined by the number of times they are turned on and the period of use, and they usually need to be replaced after about a year. In order to do this, the bottom cover of the sign body must be removed, the advertising face plate must be removed, and the fluorescent lamp portion must be exposed before these can be replaced.

Of course, for large-sized signboards, the advertising face plate is framed in a special frame, and the frame is opened and closed by the main body and hinges, etc., so that it can be replaced, or the entire fluorescent light fixture is integrated into one unit. There is a type of frame that is assembled and then removed from the main body frame of the sign body, as shown in Japanese Utility Model Application Publication No. 49-88695.

However, the former model, which allows you to remove the bottom cover, requires time and effort to dismantle part of the sign frame, and there is also the risk of damaging the advertising board, making it difficult to replace unless you are a specialized worker. . In addition, the latter type of opening/closing type and removable type are easy to operate, but they inevitably increase costs compared to the former, and have a complicated structure, so they are still not used in the majority of signboard frames. In the current situation, the above-mentioned points are the current bottlenecks in advertising signboards with built-in lighting in the industry.

In view of the above circumstances, the present invention utilizes a conventional fluorescent lamp holder and uses a cartridge sash consisting of a fixed sash and a sliding sash as a guide rail for stable and easy sliding. It is an object of the present invention to provide a lighting equipment replacement device for an advertising signboard, which facilitates the replacement of fluorescent lights and glow bulbs of the advertising signboard.

Hereinafter, a detailed description will be given based on the embodiments shown in the drawings.

The advertising signboard frame 1 is made up of an upper angle 7a and a lower angle 7b which are pre-framed in a rectangular shape, and metal outer plates 2, 2 having flanges on both sides are integrally assembled. , 2a and 2b,
2b and both angles 7a, 7b, there is a concave-shaped gap, and transparent or semi-transparent advertising boards 3, 3 are inserted into this gap, respectively, and a top cover 4 and a bottom cover 5 are inserted into this gap. It consists of a vertically elongated regular hexahedron with

This embodiment shows an example in which a vertically long signboard is installed vertically, and the bottom cover 5 is opened downward by hinges 6, 6 as shown by the broken line in FIG. However, it is also preferable that the bottom cover 5 is secured to the lower angle 7b with square screws, and that the bottom cover 5 is removable. Note that the top cover 4 is also attached in the same way as the bottom cover 5.

Next, the advertising board 3 is made of a transparent or semi-transparent plate, and needs to be fixed in an appropriate manner so that it does not fall under its own weight when the bottom cover 5 is opened. Angle 7
A small plate fixing angle 8 is mounted on the lower part of the advertising board 3 side of b.

A slideable guide rail type sash is attached to the inside of the sign frame 1 having the above-described structure. A sliding sash 13 having a matching inversely uneven surface shape is fitted so as to be slidable in the vertical direction of the same length.
To be more specific, as shown in FIG. 4, a rail 80 of the sash 11 is provided with a barb 81 on the side thereof,
Furthermore, the rail 90 of Satsushi 13...the reverse hook 91 is also attached to the side.

It protrudes from the 0.90 side. both reverse hooks 8
The above-mentioned fitting is accomplished by the engagement of 1 and 91 with each other. This fixed sash 11 is connected to the support plates 10, 10.
are fixed to the support plates 10, 10.
are further connected to support rods 9, 9 to form a cartridge rack.

This cartridge sash is mounted at two upper and lower locations by two supporting round rods 9, 9, which straddle between the outer panels 2, 2.

The sliding fitting of both sashes 11 and 13 is controlled by giving a certain amount of resistance to sliding so that the sliding sash 13 does not fall suddenly in the case of a vertical signboard as in this embodiment. It is preferable to do so. One example of this is to narrow the gap between the slits in which the two sashes 11 and 13 fit so that they fit tightly together, and another example is to insert a leaf spring 14 30 into the fixed sash 11 as shown in FIG. Alternatively, as another example, the sliding fitting of both sashes 11 and 13 can be controlled by interposing an elastic body 15 such as a cushion material made of soft polyurethane foam as shown in FIG.

The uneven shape of both sashes 11 and 13 is as shown in 1 in Fig. 5.
It is also possible to have a rounded uneven shape such as 1a and 13a. Yet another example is the seventh
As shown in the figure, the fixed sash 11b and the sliding sash 13b
It is also possible to have an asymmetric shape. However, although both the sashes 11 and 13 are made of aluminum or iron, the fixed sash 11 and the sliding sash 13 are symmetrically similar as shown in FIG. 2, 4, 6, or 5. If this is done, production can be performed using one mold, which is preferable since it can reduce costs. In the case of FIG. 5, 80' and 90' correspond to the rails 80 and 90 in FIG. 4, respectively.
91' correspond to the reverse hooks 81 and 91 in FIG. 4, respectively.
Also in the case of FIG. 7, 81'' and 91'' correspond to the rails 80 and 90 of FIG. 4, respectively, and 81'' and 91'' correspond to the reverse hooks 81 and 91 of FIG. 7, respectively.

In the fixed position where both the fixed sash 11 and the sliding sash 13 are fitted, a removable piece is inserted into the hole 16 drilled at the bottom of the fixed sash 11 and the hole 17 drilled at the bottom of the sliding sash 13. Locking tool 1 consisting of a split pin
8 and lock it. This locking device 18 may be a bolt.

An upper stopper 19 is attached to the inner bottom of the upper end of the sliding sash 13 with a pin 31, while the above-mentioned locking tool 1 is attached to the inner bottom of the lower end of the fixed sash 11.
A lower stopper 20 is similarly attached with a pin to the upper part of the hole 16 in which the stopper 8 is locked. However, these stoppers 19 and 20 are not essential, and if a stopper is provided on the upper part of the fixed sash 11 (not shown) so that the sliding sash 13 can be fitted into the position, it is possible to It is also easy to insert the locking tool 18 made of a split pin.

Next, a vertically elongated fluorescent light channel 21 is vertically fixed to the sliding sash 13, and fluorescent light arms 2 are horizontally fixed to the upper and lower ends of the channel 21.
2 and 22 are fixedly protruding horizontally. However, the fluorescent arm 22 may also be pre-integrated with the fluorescent channel 21.

The fluorescent lamp arms 22, 22 have sockets 2 at their ends.
In this embodiment, a set of lighting fixtures 24 consisting of two fluorescent lamps is attached vertically to the left and right through the 3.
A glow lamp 25 and a ballast 26 are attached. Although the cords connecting these are not shown, the cords connecting the left and right lighting fixtures 24 have connectors 28 and 29, respectively, which can be removed.
9, 29 are cords 2 bundled together as shown in FIG.
It is linked to 7.

The device of the present invention has the above configuration, but
Next, its action and effects will be explained.

In the vertical signboard of this embodiment, which is attached to the roof or wall of a building, the bottom cover 5 is opened in order to replace the internal lighting equipment, but the hinges 6, 6 are left open downward, and the screws are secured. If necessary, remove the bottom cover 5. Next, the lighting fixture 2 on either the left or right side to be replaced.
When only the connectors 28 and 29 connecting 4 are removed and the locking tool 18 consisting of a split pin or bolt is removed, the sliding sash 13 becomes free and slides on the uneven surface of the fixed sash 11. However, due to the close fitting between the two sashes 11 and 13, and the braking by the leaf spring 14, elastic body 15, etc., the sliding movement is prevented from falling suddenly. The entire lighting fixture 24 attached to the moving sash 13 is taken out of the signboard frame 1. At this time, if the upper stopper 19 is attached to the inner bottom of the upper end of the sliding sash 13 and the protrusion of the lower stopper 20 is attached to the inner bottom of the lower end of the fixed sash 11,
The lighting fixture 24 is replaced at the position where both stoppers are locked. However, if both stoppers 19 and 20 are not installed, or if both stoppers are designed to be removable, the entire sliding sash 13 to which the set of lighting fixtures 24 is attached can be removed from the fixed sash 11 and placed separately. The lighting fixture 24 should be replaced at a safe place.

Once the defective lighting fixture 24 has been replaced with a new one as described above, the sliding sash 13 is fitted into the fixed sash 11 and pushed up again while sliding, until the entire surface of both sashes 11 and 13 is covered. In the fixed position where it is fitted, although not shown in this case,
If a stopper is provided at the top of the fixed sash 11, positioning will be easier.
Then, insert it into the hole 16 of the fixed sash 11 and lock it. Thereafter, the removed connectors 28 and 29 are connected to allow current to pass therethrough, and the bottom cover 5 is closed to complete the replacement work.

As in the above embodiment, the present invention allows the entire set of lighting fixtures 24 to be easily taken out outside the signboard frame 1, making it possible to replace the lighting fixtures of advertising signboards at dangerous heights in tight spaces. It is no longer necessary to work inside the signboard frame 1 or to remove the advertising board 3 made of a large transparent or translucent plate, and only the light set of lighting fixtures 24 inside can be taken out, making the work much easier. Ta.

As mentioned above, the device of the present invention is easy to operate, inexpensive, and consists of a highly practical and useful device that solves the problems that have been a bottleneck in conventional advertising signboards with built-in lighting. be.
