(See Patent Document 1)

JP 2004-338825 A (paragraphs 0029 to 0033, FIG. 2)

  In the above-described conventional cab lighting device, the light emitting panel and the translucent plate have a gap corresponding to the length of the column. For this reason, the light-receiving surface of the light-transmitting plate that receives light from the light-emitting element is easily contaminated by dust that has entered between the light-emitting panel and the light-transmitting plate, and thus the light-receiving surface has to be frequently cleaned. Moreover, since the conventional cab lighting device is on a business trip in the cab, there is a concern that it may give a passenger a feeling of pressure.

  The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide an elevator that can protect the light-receiving surface of a light-transmitting plate from dirt caused by external dust and can reduce the size of a protrusion in a car room. It is to provide a cab lighting device.

  In order to achieve the above object, the present invention is configured as follows.

[1] An elevator cab lighting device according to the present invention includes a ceiling plate that forms a ceiling of a passenger car cab, and a surface on the side of the cab that is spread in a direction substantially parallel to a direction in which the ceiling plate extends. A light-emitting panel provided with a light-emitting element, a light-transmitting plate provided so as to cover the surface of the light-emitting panel on the side of the cab, and fixing for fixing the light-emitting panel and the light-transmitting plate to the ceiling plate A light emitted from the light emitting element is transmitted through the light transmissive plate while being diffused by the light transmissive plate to illuminate the interior of the car. Is provided with an opening penetrating therethrough, and the translucent plate forms a recess opening on the light emitting panel side and is inserted into the opening from the light emitting panel side, and the entire outer periphery of the main body portion Projecting from the ceiling plate An annular retaining portion that is hooked on the ceiling plate around the opening, and an edge portion of the light emitting panel that is positioned above the retaining portion and that is positioned around the light emitting element is mounted. An annular support portion, wherein the light-emitting panel is positioned so as to close the recess when the edge of the light-emitting panel is placed on the support portion.

  When the elevator cab illumination device described in “[1]” illuminates the interior of the cab, the light emitted by the light emitting element is received by the inner surface of the concave portion of the main body of the translucent plate, that is, the light receiving surface. Since the main body is inserted into the opening of the ceiling plate, the light received by the light receiving surface is transmitted through the main body while being diffused and reaches the car room.

  In particular, in the elevator cab illumination device described in “[1]”, the light emitting panel is a concave portion of the main body of the light transmitting plate in a state where the edge of the light emitting panel is placed on the support portion of the light transmitting plate. Therefore, the dust does not enter the recess from the outside, and therefore, the light receiving surface (the inner surface of the recess) of the translucent plate can be protected from contamination by external dust.

  Furthermore, in the cab lighting device described in “[1]”, the translucent plate is hooked on the ceiling plate around the opening by the retaining portion, and the light emitting panel is supported by the support portion on the main body portion above the retaining portion. Position with respect to the lower end (the end on the cab side). Thereby, the whole light emission panel and the part of the translucent board located in the area | region from the lower surface of a ceiling board to the surface by the side of the cab of a light emission panel do not make a business trip below a ceiling board. Therefore, the projecting dimension of the car room lighting device into the car room can be made smaller than before, or the projecting dimension can be eliminated.

[2] The elevator cab illumination device according to the present invention is the elevator cab illumination device according to “[1]”, wherein the light emitting panel and the main body are interposed between the retaining portion and the support portion. The spacer part which absorbs a part of area | region occupied to the lower end of a part in the area | region above the said ceiling board was provided.

  In the cab lighting device described in “[2]”, the spacer portion only occupies the vertical dimension of the region absorbed by the region above the ceiling plate in the region occupied from the light emitting panel to the lower end of the main body. The projecting dimension from the ceiling board to the car room can be shortened. In addition, the vertical distance between the light emitting panel and the inner surface (light receiving surface) of the concave portion of the main body can be ensured without increasing the projecting dimension of the light transmitting plate from the ceiling plate. As a case where it is particularly necessary to secure the interval, for example, there is a case in which surface light emission is caused to emit light substantially uniformly on the surface exposed in the car room of the main body portion of the translucent plate.

[3] The elevator cab lighting device according to the present invention is the elevator cab lighting device according to “[1]” or “[2]”, wherein the fixing means covers the light emitting panel from above. A cover member detachably attached to the upper surface of the ceiling board, and a pressing means provided on the cover member or the light-emitting panel and pressing the light-emitting panel against the support portion by an elastic force. .

  In the elevator cab lighting device described in “[3]”, since the fixing means is located on the upper surface of the ceiling plate, the fixing means can be prevented from being exposed in the car room, and the light emitting panel is formed by the cover member. Can be protected. The light emitting panel and the light transmitting plate can be fixed to the ceiling plate by pressing the light emitting panel against the supporting portion of the light transmitting plate by pressing means simultaneously with the mounting of the cover member to the ceiling plate. Simultaneously with the removal of the light-emitting panel, the light-emitting panel and the translucent plate can be unfixed from the ceiling plate.

  As described above, the car room lighting device according to the present invention can protect the light receiving surface of the translucent plate from dirt caused by external dust, and can reduce the projecting dimension into the car room. Accordingly, the frequency of cleaning the car room lighting device can be reduced, and the feeling of pressure given to passengers in the car by the car room lighting device can be reduced.

It is a perspective view at the time of seeing the cage room of the escalator which concerns on 1st Embodiment of this invention toward the cage door side from the back | inner side of this cage room. It is a disassembled perspective view of the cab illuminating device according to the first embodiment. It is a longitudinal cross-sectional view of the cab illuminating device according to the first embodiment. It is an enlarged view of one side part of the cab lighting device shown in FIG. It is a longitudinal cross-sectional view of the cab illuminator before being renewed in the cab illuminator shown in FIG. It is a longitudinal cross-sectional view of the cab lighting device according to the second embodiment.

  The cab illumination device according to the first and second embodiments of the present invention will be described.

[First Embodiment]
The cab illumination device according to the first embodiment will be described with reference to FIGS.

  As shown in FIG. 1, the ceiling of the elevator cab 1 is formed by a ceiling plate 2. The ceiling board 2 is provided with four lamps for the cab lighting device 10 according to the first embodiment. In addition, 4 in FIG. 1 is a cage door.

  As shown in FIGS. 2 and 3, the cab lighting device 10 has a ceiling plate 2 that forms the ceiling of the cab 1 and a position that extends in a direction substantially parallel to the spreading direction (horizontal direction) of the ceiling plate 2. A light-emitting panel 20 provided with LEDs 22 (see FIG. 3) as light-emitting elements on the surface on the side of the room 1, and a translucent plate provided so as to cover the lower surface 21a (the surface on the side of the car room 1) of the light-emitting panel 20 30.

  The light emitting panel 20 includes a substrate 21 that is a plate member that is located in a direction substantially parallel to the direction in which the ceiling plate 2 extends and is formed in a rectangular shape. A plurality of LEDs 22 are arranged on the lower surface 21 a (surface on the side of the cab 1) of the substrate 21. The interval between the adjacent LEDs 22 is constant, and the substrate 22 is scattered uniformly over substantially the entire surface of the substrate 21 on the cab 1 side. However, the LED 22 is not provided on the edge portion 21 c of the substrate 21. A connector 23 is provided on the upper surface 21b of the substrate 21 (the surface opposite to the cab 1 side). The connector 23 is electrically connected to all the LEDs 22 and connected to the wiring 24. The plurality of LEDs 22 are lit by the power supplied from the power source via the wiring 24.

  The ceiling plate 2 is provided with a rectangular opening 3 penetrating therethrough. The translucent plate 30 is an acrylic member that exhibits surface emission performance by translucency and light diffusibility, and is formed in a rectangular shape when viewed from above. The translucent plate 30 includes a concave body 31a that opens on the light emitting panel 20 side, a rectangular-shaped main body portion 31 inserted into the opening 3 from the light emitting panel 20 side, and a ceiling from the entire outer periphery of the main body portion 31. An annular retaining part 32 provided so as to project in the spreading direction of the plate 2 and an annular support part 33 positioned above the retaining part 32 are provided. The retaining portion 32 is caught on the upper surface of the ceiling plate 2 around the opening 3. On the support portion 33, the edge portion 21c of the light emitting panel 20 positioned around the entire plurality of LEDs 22 is placed. In a state where the edge portion 21c of the light emitting panel 20 is placed on the support portion 33, the entire edge portion 21c is in surface contact or line contact with the support portion 33, whereby the light emission panel 20 is positioned closing the recess 31a.

  The projecting dimension X1 of the main body 31 with respect to the lower surface 2a of the ceiling board 2 is determined by the projecting dimension h of the main body 31 from the retaining part 32. Naturally, the projecting dimension h is smaller as the projecting dimension h is smaller. Therefore, when it is feared that the projecting dimension X1 gives a feeling of pressure to the passengers in the car, the projecting dimension h may be set small, so that, for example, it becomes substantially the same surface as the lower surface 2a of the ceiling board 2. You may set the protrusion dimension h.

  In the cab lighting device 10, the main body 31 of the translucent plate 30 is inserted into the opening 3 of the ceiling plate 2 as described above. Accordingly, when the car room illumination device 10 illuminates the car room 1, the light emitted by the LED 22 is received by the inner surface of the concave portion 31 a of the main body part 31 of the translucent plate 30, that is, the light receiving surface. The inside of the car room 1 is illuminated by causing surface emission at the lower surface 31c.

  The translucent plate 30 includes a spacer portion 34 between the retaining portion 32 and the support portion 33. The spacer portion 34 rises substantially perpendicular to the spreading direction (horizontal direction) of the retaining portion 32 and the support portion 33. The main body portion 31, the retaining portion 32, the spacer portion, and the support portion 33 form a step shape as a whole. The spacer part 34 absorbs a part of the area occupied by the light emitting panel 20 to the lower end of the main body part 31 in an area above the ceiling plate 2. The height dimension from the retaining part 32 to the support part 33 is set to the height dimension i by the spacer part 34. The total dimension j of the height dimension i and the protrusion dimension h is to cause surface light emission that emits light substantially uniformly on the lower surface 31c, which is the surface exposed to the cab 1 of the main body 31 of the translucent plate 30. It is set as an appropriate dimension. When the brightness of the LED 22 and the surface light emission performance of the main body 31 are not changed, the total dimension j cannot be shortened. Therefore, if the protrusion dimension h is set small to reduce the protrusion dimension X1, the height dimension h is set large, and at the same time, the protrusion dimension X2 of the cover member 41 with respect to the upper surface 2b of the ceiling plate 2 is also increased. Will be set. In order to largely change the projecting dimension X2, it may be necessary to increase the overhead dimension of the car hoistway. While it is generally desirable to save space in elevators, design changes that increase the overhead dimension of the hoistway are not desirable. The protrusion dimension h and the height dimension i are set so that X1 becomes small.

  The dimensional relationship between the main body 31 and the opening 3 is set so that a gap S is generated between the outer surface 31 b of the main body 31 of the translucent plate 30 and the inner surface 3 a of the opening 3 of the ceiling plate 2. Yes. The gap S allows the main body 31 to be inserted into and removed from the opening 3. Further, the inner side surface 3 a of the opening 3 suppresses the movement of the main body 31 in the horizontal direction.

  Further, an annular restricting portion 35 is provided on the outer edge portion of the support portion 33 so as to protrude upward, and the restricting portion 35 restricts the movement of the light emitting panel 20 in the direction parallel to the spreading direction of the ceiling plate 2. Has been.

  Further, the car room lighting device 10 includes a fixing means 40 that fixes the light emitting panel 20 and the light transmitting plate 30 to the ceiling plate 2 on the ceiling plate 2. The fixing means 40 includes a cover member that covers the light emitting panel from above and is detachably attached to the upper surface of the ceiling plate 2, and a pressing means that is provided on the cover member 41 and presses the light emitting panel 20 against the support portion 33 by elastic force. And a plate spring 42 made of steel.

  The cover member 41 has a rectangular parallelepiped outer shape, and has a concave shape with an opening on the lower side. An attachment hole 41 b is provided on the side of the cover member 41, and one side 43 a of an L-shaped attachment fitting 43 is attached to the attachment hole 41 b with a screw 44. The other side 43 b of the mounting bracket 43 is fixed to the upper surface of the ceiling board 2.

  Two leaf springs 42 are provided in the approximate center of the upper plate portion 41 a inside the cover member 41. These leaf springs 42 are diverging downward. The light emitting panel 20 is pressed against the support portion 33 by the leaf spring 42 in addition to being restricted by the restriction portion 35 of the light transmission plate 30 in the horizontal direction while being placed on the support portion 33 of the light transmission plate 30. Therefore, it is fixed to the ceiling plate 2.

  By the way, the existing cab lighting apparatus 100 includes the existing cab lighting apparatus 100 shown in FIG. This existing cab illumination device includes a cover member 101 having the same shape as the cover member 41 of the cab illumination device 10 according to the first embodiment. The cover member 101 is screwed to a mounting bracket 43 that is fixed to the ceiling board 2. An annular fluorescent tube 102 is attached to substantially the center inside the cover member 101. An opening 3 is opened in the ceiling plate 2, and a light transmitting plate 103 having a shape different from that of the light transmitting plate 30 in the first embodiment is inserted into the opening 3. The configuration of the existing cab lighting device 100 is common to the configuration of the cab lighting device 10 according to the first embodiment in that the opening 3 is opened in the ceiling plate 2. Therefore, when the existing cab lighting device 100 is renewed, the opening 3 can be used and replaced with the cab lighting device 10 according to the first embodiment. With this renewal, the construction period can be shortened and the cost can be reduced rather than renewing the entire ceiling structure of the cab.

  The renewal procedure will be described next.

  First, the existing cab lighting device 100 is removed. In this removal operation, the worker first gets on the upper part of the car and removes the wiring 24 connected to the control box (not shown). Next, the cover member 101 is removed from the mounting bracket 43. Next, the fluorescent tube 102 is removed from the cover member 101, and the translucent plate 103 is removed from the ceiling plate 2. Finally, the periphery of the opening 3 exposed by removing the translucent plate 103 is cleaned, and the removal operation is completed.

  Next, the installation work of the cab lighting device 10 is performed. In this new construction work, the worker first gets on the upper part of the car and inserts the main body 31 of the translucent plate 30 into the opening 3 of the ceiling plate 2 and penetrates the ceiling plate 2 around the opening 3. The retaining part 32 of the optical plate 30 is placed and hooked. Thereby, the translucent plate 30 is held at the position of the opening 3. Next, the edge portion 21 c of the light emitting panel 20 is placed on the support portion 33 of the translucent plate 30. In this state, the light emitting panel 20 is restricted from moving in the horizontal direction by the restricting portion 35. Next, the wiring 24 is electrically connected to the connector 23 of the light emitting panel 20. Next, the wiring 24 is passed through the through hole 41c of the cover member 41, and the cover member 41 in this state covers the light emitting panel 20 and the light transmitting plate 30 from above, and each of the two mounting holes 41b has two mounting brackets. The cover member 41 is placed on the upper surface 2 b of the ceiling plate 2 so as to be arranged at the respective positions 43. Next, the cover member 41 is screwed to the two mounting brackets 43. In this state, the light emitting panel 20 is pressed against the support portion 33 of the light transmitting plate 30 by the elastic force of the two plate springs 42, and the retaining portion 32 of the light transmitting plate 30 is pressed by the elastic force of the two plate springs 42. 20 is pressed against the upper surface of the ceiling plate 2, whereby the light emitting panel 20 and the light transmitting plate 30 are fixed to the ceiling plate 2. Finally, the wiring 24 is electrically connected to the control box, and the new work is completed.

  According to the cab lighting device 10 according to the first embodiment, the following effects can be obtained.

  In the cab lighting device 10 according to the first embodiment, the light emitting panel 20 is positioned so as to block the recess 31a in a state where the edge portion 21c of the light emitting panel 20 is placed on the support portion 33 of the light transmitting plate 30. Dust does not enter the recess 31a from the outside, and therefore, the light receiving surface (the inner surface of the recess) of the translucent plate 30 can be protected from dirt due to external dust. Thereby, the frequency of cleaning of the cab lighting device can be reduced.

  In the cab lighting device 10 according to the first embodiment, the translucent plate 30 is caught by the ceiling plate 2 around the opening 3 by the retaining portion 32, and the light emitting panel 20 is supported by the supporting portion 33 above the retaining portion 32. By positioning with respect to the lower end of the main body 31 (the end on the cab 1 side). As a result, the entire light emitting panel 20 and the portion of the translucent plate 30 located in the region from the lower surface 2a of the ceiling plate 2 to the lower surface 2a of the light emitting panel 20 (surface on the cab 1 side) are below the ceiling plate 2. I will not be on a business trip. Therefore, the projecting dimension of the car room lighting device into the car room can be made smaller than before, or the projecting dimension can be eliminated. Thereby, the feeling of pressure given with respect to the passenger of a passenger car by the cab illuminating device can be reduced.

  The cab lighting device 10 according to the first embodiment is a region occupied by the spacer portion 34 of the light transmissive plate 30 from the light emitting panel 20 to the lower end of the main body portion 31 of the light transmissive plate 30 (region related to the dimension j). The projecting dimension from the ceiling board 2 into the cab 1 can be shortened by the vertical dimension “j−X1” of the area absorbed in the area above the ceiling board 2. Further, the vertical distance between the light emitting panel 20 and the inner surface (light receiving surface) of the recess 31 a of the main body 31, that is, the distance (dimensions) for generating appropriate surface light emission at the lower end of the main body 31 of the translucent plate 30. j) can be secured without increasing the projecting dimension of the translucent plate 30 from the ceiling plate 2.

  In the cab lighting device 10 according to the first embodiment, since the fixing means 40 is located on the upper surface 2b of the ceiling board 2, the fixing means 40 can be prevented from being exposed in the cab 1, and the cover member 41 is provided. Thus, the light emitting panel 20 can be protected. Simultaneously with the attachment of the cover member 41 to the ceiling plate 2, the light emitting panel 20 is pressed against the support portion 33 of the translucent plate 30 by the two leaf springs 42 (pressing means) so that the light emitting panel 20 and the support portion 33 are attached to the ceiling plate 2. In addition, the light emitting panel 20 and the translucent plate 30 can be unlocked from the ceiling plate 2 simultaneously with the removal of the cover member 41 from the ceiling plate 2.

  The cab lighting device 10 according to the first embodiment uses the opening 3 of the ceiling plate 2 of the existing cab lighting device 100, the mounting bracket 43, and the screw 44 to remove the existing cab lighting device 100 from the existing cab lighting device 100. Renewal can be performed, which can contribute to shortening the renewal work period and cost.

  In the first embodiment described above, the pressing means provided on the cover member 41 and pressing the light emitting panel 20 against the support portion 33 by elastic force is the leaf spring 42. However, the pressing means in the present invention is limited to the leaf spring. It may be a rubber elastic member or a urethane resin elastic member. Further, the place where the pressing means is provided may be the light emitting panel 20 instead of the cover member 41.

  In the first embodiment, the edge portion 21c of the light emitting panel 20 is directly placed on the support portion 33 of the light transmitting plate 30, but a packing made of rubber, silicon, or the like is attached to the edge portion 21c of the light emitting panel 20. You may interpose between support parts 33. Thereby, the performance which prevents the light-receiving surface of the translucent plate 30 from being soiled can be improved.

The surface light emission performance of the translucent plate 201 is the same as that of the translucent plate 30. The configuration of the cab lighting device 200 other than the translucent plate 201 is the same as the configuration of the cab lighting device 10.

  The translucent plate 201 of the cab illumination device 200 does not include the spacer portion 34 unlike the translucent plate 30 of the cab illumination device 10. In addition, although it can also be considered that the plate | board thickness of the translucent plate 201 is functioning as a spacer part, since the function as a spacer part by the plate | board thickness in 2nd Embodiment is not substantial, in 2nd Embodiment Does not adopt that idea. When the translucent plate 201 does not include the spacer portion 34 as described above, the projecting dimension X1 of the main body portion 31 with respect to the lower surface of the ceiling plate 2 is the first implementation in order to ensure the dimension j necessary for appropriate surface light emission. It is set to be larger than the transparent plate 30 in the form.

  According to the cab lighting device 200 according to the second embodiment, the edge portion 21c of the light-emitting panel 20 is placed on the support portion 33 of the translucent plate 201 as in the cab lighting device 10 according to the first embodiment. In this state, the light emitting panel 20 is positioned so as to block the recess 31a, so that dust does not enter the recess 31a from the outside. Therefore, the light receiving surface (inner surface of the recess) of the light transmitting plate 201 is soiled by external dust. Can be protected from. Thereby, the frequency of cleaning of the cab lighting device can be reduced. Further, the entire light emitting panel 20 and the portion of the translucent plate 201 located in the region from the lower surface 2a of the ceiling plate 2 to the lower surface 21a of the light emitting panel 20 (the surface on the car room 1 side) are located below the ceiling plate 2. Don't go on a business trip. Therefore, the projecting dimension of the car room illumination device into the car room 1 can be made smaller than before, and thereby the feeling of pressure given to the passengers of the car by the car room illumination device can be reduced.
