Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator indicator light, and particularly to improvement of a support structure for a display body with respect to a case.

[Conventional technology]

Figures 10 and 11 are for example Utility Kai 53-2854.
It is a drawing of the conventional indicator light for elevators shown in the patent publication. This elevator indicator light is case 7
The case 7 is buried in the wall 9 so that the opening 7a and the wall 9 are flush with each other, and inside the case 7, a light source 3 and a socket 4 for illuminating the display 1 are provided on the mounting plate 5. A pair of upper and lower leaf springs 6 for holding the display body 1 are attached to the mounting plate 5.
A curved portion 6a is formed at the tip of each leaf spring 6, and is engaged with a recess 1b in a mounting surface 1a of the display 1 to integrate the display 1 with the case 7. In addition, in order to match the concave portion 1b of the display body 1 and the curved portion 6a of the leaf spring 6, the mounting plate 5 is
It can be moved forward or backward using an adjustment screw 8 provided on the bottom of the case 7.

The display body 1 is usually made of transparent acrylic resin, with the exposed part having a transparent polished surface, the mounting surface 1a and the back surface being sandblasted, and the back surface having a patch plate made of milky white acrylic resin or colored acrylic resin. 2 is provided so that the light from the light source 3 is sufficiently diffused and guided.

Conventionally, in order to attach the backing plate 2 to the display body 1, the two are bonded with adhesive, or a metal fitting having a long hole is attached to the inner surface of the case 7 using a stud (not shown) provided on the inner surface of the case 7. Alternatively, although not shown in the drawings, measures have been taken such as pressing the display body 1 and the backing plate 2 with metal fittings from the back side of the case 7 so that they come into contact with each other.

Another conventional example is the one shown in FIG.
is attached with screws 8, and the display body 1 is held in place by the pressing force of the leaf spring 6. In this case as well, the cover plate 2 is fixed to the back surface of the display body 1 with adhesive.

[Problems to be Solved by the Invention] The conventional elevator indicator light as described above has a structure in which the mounting surface 1a of the display body 1 is directly pressed by the leaf spring 6. If the number of times the display 1 is pulled out of the case 7 to convert the display increases over the years, the mounting surface 1a of the display 1 may be damaged by contact with the leaf spring 6, resulting in a loss of appearance. There was a problem.

Furthermore, in the case where the backing plate 2 is attached to the back surface of the display body 1 with adhesive, uneven coating of the adhesive may be visible, and in such cases, the appearance is similarly poor, and the light source 3 There was also a problem in that the adhesive deteriorated due to the heat and the patch plate 2 was likely to fall off.

Furthermore, the structure in which the backing plate 2 is pressed against the display body 1 using metal fittings has the disadvantage that the number of parts and the number of processing and adjustment steps increase, leading to an increase in cost.

The present invention has been made to solve these problems, and the mounting surface of the display body will not be damaged even when the display body is inserted and removed from the case, and furthermore, the backing plate placed on the back side of the display body can be easily attached. It is an object of the present invention to provide an elevator indicator light that can be reliably installed and maintained.

[Means for solving problems]

In the elevator indicator light according to the present invention, display body engaging parts are provided on at least two opposing mounting surfaces of the display body that can be inserted into the case, and a patch plate engaging part is also provided on the backing plate. The display body and the patch plate are brought into close contact by locking the display body engagement part and the patch plate engagement part to the support body engagement part formed on the support body having a length that extends into the back of the case. In this state, the display body and the case are integrated by holding the support body inserted into the case with a fixture inside the case.

[Effect]

In this invention, the display is inserted into the case with the support sandwiched between at least two opposing mounting surfaces of the display, and the support is held by the support engaging portion. Then, the display body engaging portion and the backing plate engaging portion are locked to bring the backing plate into close contact with the back surface of the display body, and in this state, the display body and the case are removably integrated.
