Abstract

PURPOSE:To improve the fitting workability of a display panel by forming an upper groove section and a lower groove section coupling upper and lower edge sections of the display panels, and forming a guide section with an inside coupling edge piece section made longer than an outside coupling edge piece section and a tip section protruded to the apparatus main body inside then an opening section. CONSTITUTION:Both ends of a display panel 38 are held, an upper edge is inserted and coupled with a groove 20, the lower edge of the display panel 38 is inserted into a groove 20a, and upper and lower edges of the display panel 38 are coupled and held in upper and lower grooves 20 and 20a. When the display panel 38 is coupled with grooves 20 and 20a, inside coupling edge piece sections 19 and 19a forming grooves 20 and 20a are protruded to an opening section with their rising lengths made longer than those of outside coupling edge piece sections 18 and 18a, their tips are tilted inward, thus the display panel 38 faced obliquely upward is guided by the guide section 23 of the inside coupling edge piece section 19 and can be easily fitted when the display panel is inserted into the upper groove 20.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Industrial Application Field) The present invention relates to an indicator light fixture, such as a guide light, which requires a display panel to be attached.

(Prior Art) As a guide light fixture in which a translucent display panel is provided opposite to a lamp, an indicator light fixture described in, for example, Japanese Utility Model Publication No. 62-40361 is widely known. This conventional indicator light fixture has a structure in which a panel frame with a display panel or back plate attached is removably attached to the front and rear openings of the fixture body.This structure requires a panel frame, and Since it is necessary to attach and detach the display panel using screws, it has the problem of poor workability.Therefore, grooves are formed in the front and rear openings of the instrument body, and the upper and lower edges of the display panel are engaged with these grooves. A structure has been proposed in which the display panel can be installed by first inserting the upper edge of the display panel into the upper groove, and then dropping the lower edge of the display panel into the lower groove. .

(Problem to be Solved by the Invention) In the device in which the upper and lower edges of the display panel are engaged with the upper and lower grooves formed in the opening of the device body, the upper and lower edges of the display panel are engaged with the upper and lower grooves of the device body. There is a problem that it is difficult to insert the display panel into the groove because there is no guide means when inserting the display panel, and since the display panel is loosely inserted into the groove when it is installed, the display panel may shake due to vibration etc. There was a problem. Therefore, it has been a challenge for this type of indicator light fixture to hold the display panel while improving the workability of mounting the display panel. The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a display light fixture in which the display panel can be easily held while improving the workability of mounting the display panel.

[Structure of the invention] (Means for solving problems) The invention will be explained with reference to FIG.

10 is an indicator light fixture body, which has an opening 2 at least on the front side.

Similar to the upper edge of the opening 22, the lower groove 208° guide portion 23
a is formed on the lower side of the guide portion 23, an outer engaging edge piece portion 18a,
In order for the display panel 38 to be sandwiched between the inner engaging edge pieces 198, the sandwiching portions are formed at intervals equal to or less than the wall thickness of the lower edge of the display panel 38. Note that the holding portion may also be formed at the upper edge of the opening 22.

(Function) With the above configuration, when the display panel 38 is mounted, the present invention first attaches the upper edge of the display panel 38 to the opening 22.
Insert the display panel 38 into the guide part 23 on the upper edge, push up the display panel 38 to the deep part of the upper groove 20, and then push the display panel 38 up.
The lower edge is inserted into the guide portion 23 at the lower edge of the opening 22, and the display panel 38 is dropped into the inner part of the lower groove 20a. At this time, the display panel 38 is held by the holding parts A.

If the upper groove 20 does not have a holding part, the display panel 38 can be pushed up and inserted into the guide part 23 smoothly. In addition, if the upper groove 20 also has a holding part, the display panel 38
Since the display panel 38 is held at both the upper and lower edges of the display panel 38, strong holding can be achieved.

The upper edge is inserted into and engaged with the groove 20, and then the second contact portion 44 of the upper and lower edges of this back plate 39 is inserted into the inner engaging edge piece portion 19.1.
9a, the first contact portions 41 are brought into contact with the outer engaging edge pieces 18.18a, respectively, and the grooves 10.10a of this back plate 39 are aligned with the thicker display panel 38. Even if the groove width is formed, the groove 20 will not move freely.
．． 208. Then, the covers 29 and 30 are each moved inward, and both ends of the display panel 38 and the back plate 39 are held by the covers 29 and 30.

Also, when replacing the lamp 35 or battery 49,
As shown in FIG. 4, the covers 29 and 30 are moved outward to the range of movement that is regulated by the engagement between the regulation holes 27 and 28 of the case frame member 16 and 17 and the elastic engagement protrusions 31 and 32, respectively. Move the display panel 38 or back plate 39 by grasping both ends and lift it up, move the upper edge above the groove 20a, remove the lower edge from the groove 20a, and then remove the upper edge of the display panel 38 or the back plate 39. Remove it from the groove 20 and replace the lamp 35 or battery 49.

In addition, when inspecting or repairing the ballast 48 and the lighting circuit unit board 51, the covers 29 and 30 are moved outward and the regulation holes 27 and 28 of the case frame member 16 and 17 are opened.
, remove the cover 29.20 from the case frame member 16.17, and inspect it from the opening surface of the outer end surface of the case frame member 16.17. Carry out repairs.

Further, the lamp 35 is not limited to a straight tube fluorescent lamp, and various lamps such as an annular lamp and a U-shaped lamp can be used.

The tube portion of the rough lamp 35 is not limited to a circular shape, but a lamp having an oblate circular cross section may also be used. Further, in the above embodiments, a guide light has been described, but the present invention is not limited to guide lights and can be applied to various indicator light fixtures.

[Effects of the Invention] According to the present invention, the display panel can be closed by the inner engagement edge portion and the outer engagement edge portion provided parallel to each other along the upper and lower edges of the opening formed in the device main body. A guide in which an upper groove and a lower groove are formed to engage the upper and lower edges, and the inner engaging edge piece is longer than the outer engaging edge piece so that the tip protrudes further inside the instrument body than the opening. Since the guide part guides the edge of the display panel when inserting the edge of the display panel into the groove, it is easy to insert the display panel, and the lower edge of the display panel is inserted into the lower groove. Since the holding portions are formed to hold the display panel in place, the display panel is held when the display panel is attached to the opening, so that it is possible to prevent the display panel from wobbling.
