Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a sign plate mounting structure that can reliably and easily attach a sign plate to be attached to the front of a sign light such as a guide light.

(b) Conventional technology Conventionally, as this type of mounting device, for example,
As shown in Publication No. 44387, the bases of a plurality of mounting springs are attached to a decorative frame, and the box-shaped body is provided with protruding pieces that protrude inward at positions corresponding to the mounting springs. It is known that the protruding piece is provided with an engaging joint portion that elastically engages with the protruding piece.

However, since guide lights are often mounted overhead where people often pass by, it is necessary to strengthen the engagement between the mounting spring and the protruding piece to prevent the decorative frame from falling due to vibrations, shocks, etc., resulting in personal injury. However, if the engagement is strengthened, it becomes difficult to remove the decorative frame.

(c) Problems to be solved by the invention In view of the above-mentioned conventional drawbacks, the technical problem of the present invention is to provide a sign plate mounting device that reliably and easily attaches a sign plate to the front of a sign light. .

(d) Means for solving the problem The present invention has a plurality of mounting spring plates attached to the decorative frame, and each of the mounting spring plates has a protruding piece formed to protrude inward from the main body. It is characterized by sequentially forming a first engaging part that engages with the first engaging part, and a second engaging part that is connected to the first engaging part and that the protruding piece elastically engages with.

(E) Function Since the present invention is constructed as described above, even if the first engaging part and the protruding piece disengage from each other due to vibration or impact, the protruding piece will engage with the second engaging part, so there is no need for makeup. The frame will not fall.

(f) Example An example in which the present invention is applied to a guide light will be described in detail below based on the drawings.

Reference numeral 1 denotes a guide light body with openings on the front and rear sides, and a fluorescent light 2 is disposed inside. A decorative frame adhering edge 4 is formed at the opening edge of the main body 1 by bending the main body side plate 3 inward, and a decorative board 6 described later is adhered thereto. Reference numeral 5 denotes a protruding piece formed by providing a notch in the side plate 3 and bending it inward, with which a mounting spring plate 10, which will be described later, engages.

Reference numeral 6 denotes a decorative frame that covers the opening of the main body 1 and has a sign plate 7 made of glass, plastic, etc. inside, and includes a frame side plate 8 that is attached to the decorative frame attachment edge 4 of the main body 1, and a frame side plate 8. The front edge plate 9 is formed on the front surface of the front edge plate 9. Reference numeral 10 denotes a mounting spring plate made of an elastic metal plate.
is a base 1 fixed to the decorative frame 6 by welding or the like;
1, a support portion 12 that extends to the base 11 and prevents the sign plate 7 from falling off, a first engagement portion 13 that extends to the support portion 12 and engages with the protruding piece 5; The first guide part 1 guides the protruding piece 5 to
4. A second engaging portion 15 that connects to the first guide portion 14 and engages with the protruding piece 5; and a second guiding portion 16 that guides the protruding piece 5 to the second engaging portion 15 in a staggered manner. It consists of an engaging bent portion 17 formed by bending. The engagement angle β between the second engagement portion 15 and the protrusion piece 5 is smaller than the engagement angle α between the first engagement portion 13 and the protrusion piece 5. Further, the engagement distance b between the second engagement portion 15 and the protrusion piece 5 is formed to be larger than the engagement distance a between the first engagement portion 13 and the protrusion piece 5. Also, the guide parts 14, 16
It is desirable to have a gentle slope for easy insertion.

Then, the decorative frame 6 with the signboard 7 attached is attached to the main body 1.
When pressed from the front surface of the decorative frame attaching edge 4, the second guide portion 16 is pressed by the protruding piece 5 and the mounting spring plate 10 is bent, as shown in FIG. 15. When the decorative frame 6 is further pressed, the protruding piece 5 presses the first guide part 14 and bends the mounting spring plate 10, as shown in FIG.
The decorative frame 6 is engaged with the first engaging portion 13 and is attached to the outer side of the decorative frame attaching edge 4 of the main body 1. At this time, the first engaging portion 13 acts to press the decorative frame 6 engaged with the tip of the protruding piece 5 in an inclined state toward the main body 1, so that the decorative frame 1 is difficult to fall off.
Furthermore, even when the first engaging portion 13 and the protruding piece 5 are disengaged due to vibration or impact, the second engaging portion 15
The engagement angle β between the first engagement portion 13 and the protrusion piece 5 is made smaller than the engagement angle α between the first engagement portion 13 and the protrusion piece 5, and
The engagement distance b between the second engagement portion 15 and the protrusion piece 5 is set to the first
Since the engagement distance a between the second engaging portion 13 and the protruding piece 5 is larger than that of the second engaging portion 15, the protruding piece 5 engaged with the second engaging portion 15
will not come off easily.

When removing the decorative frame 6 from the main body 1, put your hand on the frame side plate 8 of the decorative frame 6 and pull the decorative frame 6 to disengage the first engaging portion 13 and the protruding piece 5. The decorative frame 6 can be easily removed by placing a finger in the gap between the frame side plate 8 and the side plate 3 that is created at this time and pulling strongly.

(g) Effects of the invention Since the invention is constructed as described above, the decorative frame will not fall due to vibration or impact, and there is no risk of personal injury. Further, the engagement angle between the second engagement part and the protrusion piece is made smaller than the engagement angle between the first engagement part and the protrusion piece, and the engagement distance between the second engagement part and the protrusion piece is reduced. Since the engagement distance between the first engaging part and the protruding piece is greater than the engagement distance between the first engaging part and the protruding piece, the engagement between the second engaging part and the protruding piece can be strengthened, and the decorative frame will not fall easily.
When removing the decorative frame, the relatively weak engagement between the first engaging part and the protruding piece is removed by touching the frame side plate of the decorative frame, and the frame side plate of the decorative frame and the side plate of the main body that are generated at this time are removed. It can be easily removed by disengaging the protruding piece from the second engaging part, which has a strong engagement, by firmly placing one's finger in the gap between the second engaging part and the protruding piece.
