At the time of maintenance and inspection, the illumination plate 22 is raised with its horizontal attitude kept as it is. At this time, the rollers 27 get on the second guide rail 26 upon passing through a notch 32 in the first guide rail 25 and notch 33 in the second guide rail 26. The maintenance and inspection and so on are executed while the illumination plates 22 and 23 are moved along the guide rails 25 and 26, respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an improvement of an illumination device installed on the ceiling of an elevator car.

8 to 10 are views showing the ceiling of a conventional elevator car. FIG. 8 is a front view looking up from the inside of the car. FIG. 9 is a cross-sectional view taken along line II-II in FIG. FIG. 3 is a sectional view taken along line III-III.
In the figure, reference numeral 1 denotes a ceiling of an elevator car. A suspended ceiling 2 is fixed inside the car, and an illuminating lamp 3 is installed therein. An opening 6 having ceiling joints 4 is formed in the middle in the left-right direction on the lower surface of the suspended ceiling 2, and left and right illumination plates 5 having translucent panels are provided so as to cover the opening 6. Further, on the left and right sides of the lower surface of the suspended ceiling 2, a side opening 6a and a side illumination plate 7 covering the opening 6a are arranged. Reference numeral 8 denotes an emergency rescue exit provided on the ceiling 1. 9 is a mounting metal provided at the four corners of the lighting plate 5, 10 and 11 are casters that are accommodated in the U-shaped groove 9 a above the mounting metal 9 and mounted on the mounting metal 9, and 12 are front and rear side plates of the suspended ceiling 2. The casters 10 and 11 roll on the guide rail 12 with the guide rail fixed to the inner surface.

When exchanging the illuminating lamp 3 or performing emergency rescue from the emergency rescue exit 8, as shown by the arrows in FIG. 9, the illumination plate 5 is moved horizontally to the left and right to open the opening 6, and horizontally moved in the direction opposite to the arrow. To close the opening 6.

  Since the conventional technique translates the illumination plate 5 from side to side, the space from the outer edge of the suspended ceiling 2 to the ceiling joint 4 in FIG. I can't. For this reason, there are problems that it is difficult for people to go in and out during emergency rescue, it is difficult to replace the illumination lamp near the end of the suspended ceiling 2, and the design of the ceiling illumination device is limited. Further, since the illumination plate 5 can be opened simply by moving horizontally, there is a possibility that the illumination plate 5 can be opened by mischief.

  The present invention provides an elevator illuminating apparatus having a second ceiling provided on the ceiling of an elevator car, wherein the second ceiling has a fixed portion and a plurality of movable portions, and at least one of the movable portions can be raised. And when it exists in a raise position, it is set as the structure which can move above the other movable part.

In the present invention, there are two movable parts, and one movable part can be raised and moved above the other movable part when in the raised position, and the other movable part is the one movable part. When the is in the raised position, it can be moved below.
Further, the one movable portion has a lowered position and a raised position movable along the guide rail, and is movable between the lowered position and the raised position through a notch provided in the guide rail. It is.
Furthermore, the other movable part has a fixed position and a movable position movable along the guide rail, and the fixed position is a position lower than the guide rail.

  According to the present invention, since the opening can be made wider than in the prior art, it becomes easier to perform maintenance inspections and emergency rescue operations for illumination lamps. In addition, there is an effect that the restriction on design is reduced and it is difficult to be tampered with.

An embodiment of the present invention will be described with reference to FIGS. 1 is a view corresponding to FIG. 8, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, FIG. 3 is a partial cross-sectional view taken along line BB in FIG. 5 is a cross-sectional view taken along the line CC of FIG. 4, and FIGS. 6 and 7 are diagrams showing the operating state, corresponding to FIG.
In the figure, reference numeral 20 denotes a second ceiling fixed to the car ceiling, which is the same as a conventional suspended ceiling. Reference numeral 21 denotes an opening provided in the center of the second ceiling 20, and arched illumination plates 22 and 23 having a translucent panel are provided so as to cover the opening. A bracket 24 fixed to the second ceiling 20 and first and second guide rails 25 and 26 fixed to the bracket 24 are disposed on both sides of the illumination plates 22 and 23. Rollers 27 and 28 that roll along the guide rails 25 and 26 are provided on both sides of the illumination plates 22 and 23. Reference numeral 29 denotes a side illumination plate.

  In a normal state, the illumination plates 22 and 23 are on the first guide rail 25 as shown in FIGS. Since the roller 28 of the illuminating plate 23 is fitted in the recess 31 formed in the first guide rail 25, the illuminating plates 22 and 23 hardly move in the horizontal plane. In this state, notches 32 and 33 are provided on the upper side of the first guide rail 25 and the lower side of the second guide rail 26 at positions directly above the roller 27 of the illumination plate 22 so that the roller 27 can pass therethrough. It has become.

  When opening the illuminating plates 22 and 23 during maintenance inspection or emergency rescue, the illuminating plate 22 is raised while being kept in a horizontal state, and the roller 27 is placed on the second guide rail 26 (FIG. 4) and moved sideways ( FIG. 6). Thereby, the place with the illumination plate 22 opens, and maintenance inspection and emergency rescue can be performed from here. When the illuminating plate 22 rides on the second guide rail, the illuminating plate 23 can be slightly lifted and moved on the first guide rail 25 as shown in FIG. Accordingly, it is possible to open the place where the illumination plate 23 was present and perform maintenance inspection and emergency rescue from here. 40 and 41 are stoppers for restricting movement of the illumination plates 22 and 23. When closing the illuminating plates 22 and 23, the reverse procedure is performed.

As described above, this embodiment can be opened on either side of the illumination plates 22 and 23 because the guide rail has two stages. Moreover, since it is not necessary to leave the storage space of the illumination plate on the side portions of the illumination plates 22 and 23 as in the prior art, even if there is an illumination lamp near the end of the second ceiling 20, it can be easily replaced.
Furthermore, in order to open the illuminating plates 22 and 23, the illuminating plates 22 must be lifted while being kept in a horizontal state. Therefore, the illuminating plates 22 and 23 are not opened only by pushing up the illuminating plates 22 and 23 with a long object. Therefore, it has a structure that is not easily tampered with.

  In the above embodiment, only the rollers 27 and 28 that roll along the upper and lower sides of the first and second guide rails 25 and 26 are provided, and there is no practical problem with these rollers 25 and 26 alone. Similarly to the caster 10 in FIG. 10, it is possible to provide a roller that rolls between the intermediate portions of the guide rails 25 and 26. In the above embodiment, the upper and lower guide rails are two. However, for example, a single guide rail having an E-shaped cross section may be used.

It is a figure which shows embodiment of this invention. It is AA sectional drawing of FIG. It is a BB partial sectional view of FIG. It is a figure which shows an operation state, and is a figure equivalent to FIG. It is CC sectional drawing of FIG. It is a figure which shows an operation state, and is a figure equivalent to FIG. It is a figure which shows an operation state, and is a figure equivalent to FIG. It is a figure which shows the ceiling of the conventional elevator car, and is the front view which looked up at the ceiling from the inside of a car. It is the II-II sectional view taken on the line of FIG. It is the III-III sectional view taken on the line of FIG.
