The object of the present invention is to solve the above-mentioned problems and provide a lighting device for a passenger conveyor that has an excellent lighting design and is easy to assemble and maintain.

[Means for solving problems]

In the lighting device for a passenger conveyor according to the present invention, a parapet frame is provided with projecting edges projecting from both sides of the opening end of the groove, step portions are formed on both side plates of the lighting cover, and the projecting edges protrude above the step portions of the both side plates. The upper edges of the engaging portions with wide intervals are disposed near the ceiling wall of the groove of the frame, and the stepped portions are engaged and supported on the projecting edges of the frame.

[For production]

In the lighting device for a passenger conveyor according to the present invention, by pushing the lighting cover from below into the groove opened on the lower surface of the handrail frame, the upper part of the tiered part of the lighting cover is arranged so that the distance between them is narrowed. When the stepped portion is elastically deformed and left over the protruding edges protruding from both sides of the opening end of the groove, the portion above the stepped portion almost returns to its shape before elastic deformation, and the stepped portion of the cover is It is engaged and supported on the projecting edge of the frame, and when the cover B is installed, the upper edge of the engagement part that protrudes above the stepped part of the cover almost touches the ceiling wall of the groove of the frame, and the cover itself has an attachment function. The cover can be fixed to the frame with the same width, and the cover can be removed from the frame by elastically deforming the steel plates of the cover so that their widths become narrower and pulling them downwards, so the cover can be attached and detached with ease.
Moreover, since there are no mounting brackets for the cover that expose the light emitted from the rod-shaped fluorescent lamp, it looks good.Furthermore, even if the cover is slightly bent in the longitudinal direction, especially in the vertical direction, the bend can be corrected with the frame. But it looks better.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIG. 1, the same reference numerals as those in FIGS. 7 to 9 indicate the same or equivalent parts, and the outer surface of the upper part of the lighting cover 6 at the right place in the longitudinal direction is provided with a plate made of the same material as the cover 6. Joining part 6c is glued.

They are fixed by fusion or the like, and a stepped portion 6d having the thickness dimension of the engaging portion 6C is formed by the lower edge of the engaging portion 6C.
The height of the engaging portion 6C protrudes above the side plate 6b, and the height dimension of the engaging portion 6C is from the upper surface of the projecting edge 3b of the parapet frame 3 to the ceiling wall 3C of the FR 3a.
The height dimension is slightly smaller than the height dimension up to.

Further, two opposing angle-shaped joint plates 12 are fixed to the inner surface of one end of the cover 6, and the bottom plate of the cover 6 has no screw insertion holes, and also has a mounting bracket for the lighting cover. ing.

Then, by pushing the cover 6 from below into the groove 3a opened on the lower surface of the frame 3, the portion above the stepped portion 6d of the cover 6 is elastically deformed so that the widthwise interval between these portions becomes narrower, and the frame 3 is When the stepped portion 6d passes over the protruding edge portion 3b protruding inward in the width direction from both sides of the opening end of the groove 3a, the upper and lower portions of the stepped portion 6d of the cover 6 return to the shape before elastic deformation, and the stepped portion 6d A ceiling wall 3c whose upper edge has a groove 3a and an engagement part 6C which is engaged and supported on the projecting edge part 3b and has a wide mutual interval in the width direction.
The cover 6 is fixed to the frame 3.

Further, the cover 6 can be removed from the groove 3a of the frame 3 by elastically deforming the side plates 6b of the cover 6 so that their widths become narrower and pulling them out downward. In this case, the cover 6 often has a slight bend in the vertical direction of the longitudinal direction, so that a part of the upper edge of the engaging part 6C in the longitudinal direction comes into contact with the ceiling wall 3C of 13a, Engagement part 6
c is vertically held between the projecting edge 3b and the ceiling wall 3c, preventing the cover 6 from wobbling and correcting the bending of the cover 6. Note that the configuration and operation of this embodiment other than those described above are the same as those shown in FIGS. 7 to 9.

FIG. 4 shows a modification of the lighting cover according to the present invention, and this cover 6 has a stepped portion 6d and an engaging portion 6C connected to a side plate 6b.
It is formed integrally over the entire length of these in the longitudinal direction.

5 and 6 show other modified examples of the lighting cover according to the present invention, in which the engaging portion 6c of the cover 6, which is almost the same as that in FIG. The engaging portion 6c is inclined inward to facilitate pushing the engaging portion 6c into the groove 3a of the frame 3.

The lighting cover shown in FIG. 4, and the lighting covers shown in FIGS. 5 and 6 can also be attached to and removed from the parapet frame in the same manner as the lighting covers shown in FIGS.
The same effect as the embodiment shown in the figures through FIG. 3 can be obtained.

Furthermore, in the present invention, the side plate of the lighting cover is formed to be slightly inclined outward in the width direction, and when installed in the groove of the balustrade frame, the upper end of the copper plate is pressed against the protruding edge of the side plate and pressed by elastic restoring force. By doing so, it is possible to prevent the illumination cover from slipping in the longitudinal direction using the mta force. In this invention, the balustrade frame is formed integrally with the handrail guard.

〔Effect of the invention〕

As explained above, according to the present invention, stepped portions are formed on both side plates of the lighting cover, and the upper edges of the engaging portions protruding above the stepped portions of the both side plates are disposed near the ceiling wall of the groove of the frame. In addition, since the stepped portion is engaged and supported on the protruding edges protruding from both sides of the opening end of the groove of the parapet frame, the cover itself has a mounting function without using any mounting brackets or screws. Since the cover can be attached to the frame, work efficiency during assembly and maintenance is improved, and
The light emitted from the bar-shaped fluorescent lamp surrounded by the groove wall and the cover does not need to be used in a member for attaching the cover, and therefore, it is possible to provide a lighting system for a passenger conveyor that has a good appearance and an excellent lighting design. You can get this effect.
