Description

  The present invention relates to an illumination device installed on a ceiling surface of an elevator cab.

  A conventional lighting device that is installed on the ceiling surface of an elevator cab and illuminates the interior of the cab, by installing a plurality of lighting cases on the ceiling surface of the cab and arranging lamps such as fluorescent lamps in each lighting case. There has been proposed one in which each lighting case is configured to be independently removable so that a partial replacement operation can be performed (for example, see Patent Document 1).

JP 2004-10280 A

  In the elevator car ceiling lighting device described in Patent Document 1, each lighting case is configured to be independently removable. However, replacement work of a lighting body (lamp) such as a fluorescent lamp provided in the lighting case is performed. When doing so, the elevator maintenance worker had to work on a stepladder or the like brought into the car room and facing upward. In particular, when exchanging a plurality of illuminating bodies, it has been forced to work for a long time with an unreasonable posture.

  Further, when a plurality of illuminating bodies are used, light unevenness may occur depending on the arrangement of the illuminating bodies, the structure of the illumination case, and the like. In such a case, since the holder for holding the illuminating body is disposed at an optimum position on the ceiling surface, it is necessary to newly perform screw hole processing on the ceiling surface, which causes a problem of poor workability.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object of the present invention is to provide elevator car ceiling lighting in which an illuminating body can be easily replaced and the arrangement of the illuminating body can be freely set. Is to provide a device.

  An elevator car ceiling lighting device according to the present invention includes an illuminating body that illuminates an elevator cab, a holding unit that holds the illuminating body, and an illumination case that is provided on the ceiling of the cab so as to cover the illuminating body. The magnet is provided on the upper part of the holding part, and can be attracted to the lower surface of the ceiling part in the lighting case.

  The present invention is provided on an illuminating body that illuminates an elevator cab, a holding portion that holds the illuminating body, an illumination case that is provided on a ceiling portion of the cab so as to cover the illuminating body, and an upper portion of the holding portion. By adopting a configuration that includes a magnet that can be attracted to the lower surface of the ceiling portion in the lighting case, the replacement of the lighting body is easy, and the arrangement of the lighting body can be freely set.

  In order to explain the present invention in more detail, it will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.

Embodiment 1 FIG.
1 is a side view of an elevator car ceiling lighting device according to Embodiment 1 of the present invention, and FIG. 2 is an enlarged view of a portion A of the elevator car ceiling lighting device shown in FIG. 1 and 2, reference numeral 1 denotes a car floor that forms the floor surface of the elevator cab, 2 denotes a side wall that stands on the car floor and forms a side wall of the cab, and 3 denotes an upper portion of the side wall 2. The lower surface is a ceiling part that forms the ceiling surface of the cab. In addition, the lower surface of the ceiling part 3 consists of a thin iron plate etc., and is comprised with the material which a magnet can adsorb | suck.

  Further, 4 is provided on the lower surface of the ceiling portion 3, and a plurality of illumination portions that illuminate the interior of the car room, and 5, the ceiling portion 3 so as to cover the illumination portion 4 so that the illumination portion 4 cannot be seen by users in the car room. A lighting case having an opening formed on the lower surface thereof, and a lighting plate 6 having a predetermined translucency mounted and fixed on the lighting case 5 so as to close the opening of the lighting case 5 It is.

Next, the configuration of the illumination unit 4 will be described.
In each illumination unit 4, an illuminating body 7 made of a fluorescent lamp or the like that illuminates the interior of the car is held by a holding unit 8. And the magnet 9 is provided in the upper part of this holding | maintenance part 8, and this magnet 9 is adsorbed and fixed to the lower surface of the ceiling part 3 in the illumination case 5. FIG. In addition, 10 is connected and fixed at one end to the holding portion 8 of the lighting unit 4 and at the other end to the lower surface of the ceiling portion 3 in the lighting case 5 to prevent the holding unit 8 and the lighting body 7 from falling. A fall prevention device having a predetermined length.

  FIG. 3 is an enlarged view of the fall prevention device shown in Embodiment 1 of the present invention, in which (a) is a chain and (b) is a support for supporting the illuminating body 7, the holding portion 8, and the magnet 9. The case where the wire is used is shown. Here, the chain 11 and the wire 12 are provided with an annular fixture 13 at both ends thereof, and are fixed to the lower surface of the holding portion 8 and the ceiling portion 3 via bolts 14. In addition, by comprising the fall prevention tool 10 with a metal member as shown in FIG. 3, it is strong against heat and aging deterioration and can withstand long-term use.

  With this configuration, the illumination unit 4 can be easily attached to and detached from the lower surface of the ceiling portion 3 in the illumination case 5, and the light unevenness depends on the structure of the illumination case 5, the arrangement of the openings, and the like. Even if this occurs, the light unevenness can be easily eliminated by re-installing the illuminating device 4 in an optimal place. In addition, since the illuminating unit 4 can be removed from the lower surface of the ceiling part 3 and the work can be performed on the car floor 1 in the cab, the illuminating body 7 can be replaced. Even when it is performed, the burden on the maintenance worker can be reduced and the work can be easily performed. In addition, it is not necessary to install the inspection mouth cover corresponding to each illumination part 4 like a prior art example, and it can work easily.

  In the first embodiment, the ceiling 9 is made of an iron plate or the like so that the magnet 9 can be attached to and detached from the entire lower surface of the ceiling 3 in the lighting case 5. It is also possible to predetermine a range in which to install and attach a thin iron plate or the like to the range. By having such a configuration, it is possible to easily cope with an existing elevator device that cannot attract magnets to the lower surface of the ceiling portion 3, and to facilitate maintenance management of the car ceiling lighting device after refurbishment. Can do.

Embodiment 2. FIG.
4 is a side view of an elevator car ceiling lighting device according to Embodiment 2 of the present invention, and FIG. 5 is an enlarged view of a portion B of the elevator car ceiling lighting device shown in FIG. 4 and FIG. 5, each illumination unit 4 includes a holding unit 8 that holds an illuminating body 7 made of a fluorescent lamp or the like that illuminates a car room. In the figure, reference numeral 15 denotes an adhesive side fastener fixed to the lower surface of the ceiling portion 3 of the cab with a double-sided adhesive tape 16; The adsorbing side surface fastener 15 and the adsorbing side surface fastener 17 are configured to be easily detachable by engaging with each other. In addition, the adhesive side surface fastener 15 and the adsorption | suction side surface fastener 17 consist of a Kuraray Co., Ltd. magic tape (trademark) etc., for example.

  With this configuration, the illumination unit 4 can be easily attached to and detached from the lower surface of the ceiling part 3 in the illumination case 5 regardless of the material of the lower surface of the ceiling part 3. Moreover, since the adhesive side surface fastener 15 can be attached to the lower surface of the ceiling part 3 via the double-sided adhesive tape 16 or the like, it is not necessary to perform screw hole processing on the ceiling part 3, and it can be easily applied to an existing elevator apparatus. It is possible. The other configurations and effects are the same as those of the first embodiment.
