The elevator landing includes a landing three-sided frame 1 in which a landing entrance 11 is formed, and a landing door 2 that opens and closes the landing entrance 11.

The landing three-sided frame 1 has a pair of vertical pillars 12 erected apart from each other in the frontage direction, and an upper plate 13 provided over the upper ends of each of the pair of vertical pillars 12. An elevator light emitting device 3 is attached to the lower surface of the upper plate 13. In this example, the mounting target surface on which the light emitting device 3 is mounted is the lower surface of the upper plate 13. Further, in this example, the door opening / closing warning light will be described as an example of the light emitting device 3 of the elevator.

FIG. 2 is an exploded perspective view showing the light emitting device 3 of FIG. The light emitting device 3 of the elevator includes a base 31, a light emitting substrate 32 attached to and detached from the base 31, and a cover 33 that covers the light emitting substrate 32 from below. The light emitting substrate 32 is attached to and detached from the base 31 by sliding with respect to the base 31.

The light emitting substrate 32 has a flat plate-shaped substrate portion 321 and a plurality of light emitting portions 322 fixed to the substrate portion 321. Examples of the light emitting unit 322 include an LED.

The cover 33 protects the light emitting substrate 32. The cover 33 has a peripheral portion 331 that is attached to and detached from the base 31, and a light transmitting portion 332 that is provided on the peripheral portion 331 and faces the light emitting substrate 32. The light transmitting portion 332 is made of a resin having light transmitting property.

The base 31 has a flat plate-shaped base body 311 and a pair of side wall portions 312 integrally formed on the surface of the base body 311. One of the pair of side wall portions 312 is referred to as the first side wall portion 312A, and the other of the pair of side wall portions 312 is referred to as the second side wall portion 312B.

FIG. 3 is a bottom view showing a state in which the light emitting board 32 of FIG. 2 is attached to the base 31, FIG. 4 is a side view showing the light emitting board 32 and the base 31 of FIG. It is a cross-sectional view taken along the line V. The base 31 is attached to the lower surface of the upper plate 13 using a fastener (not shown). Examples of the fastener include mounting screws and bolts.

The base body 311 is formed in a shape extending in one direction. The base 31 is arranged so that the longitudinal direction of the base main body 311 coincides with the longitudinal direction of the upper plate 13. The longitudinal direction of the upper plate 13 is arranged so as to coincide with the frontage direction of the landing door 2. The first side wall portion 312A and the second side wall portion 312B are formed so as to be parallel to each other. Further, the first side wall portion 312A and the second side wall portion 312B are formed so as to extend in the longitudinal direction of the base main body 311.

The light emitting substrate 32 is arranged between the first side wall portion 312A and the second side wall portion 312B. The direction perpendicular to the slide direction A of the light emitting substrate 32 and along the base main body 311 is defined as the substrate width direction B. By arranging the light emitting substrate 32 between the first side wall portion 312A and the second side wall portion 312B, the movement of the light emitting substrate 32 with respect to the base body 311 in the substrate width direction B is restricted. Therefore, the first side wall portion 312A and the second side wall portion 312B form a width direction regulating portion that regulates the movement of the light emitting substrate 32 with respect to the base main body 311 in the substrate width direction B.

The base 31 further has a first claw portion 313A integrally formed with the first side wall portion 312A and a second claw portion 313B integrally formed with the second side wall portion 312B. The first claw portion 313A faces one side of the surface of the light emitting substrate 32 in the substrate width direction B. The second claw portion 313B faces the other side portion of the surface of the light emitting substrate 32 in the substrate width direction B. The first claw portion 313A and the second claw portion 313B are arranged so as to be offset from each other in the slide direction A. The dimension between the first claw portion 313A and the second claw portion 313B in the slide direction A is smaller than the dimension in the longitudinal direction of the light emitting substrate 32. Since each of the first claw portion 313A and the second claw portion 313B faces the surface of the light emitting substrate 32, the movement of the light emitting substrate 32 with respect to the base main body 311 in the direction away from the base main body 311 is restricted. Therefore, the first claw portion 313A and the second claw portion 313B form a separation direction regulating portion that regulates the movement of the light emitting substrate 32 with respect to the base main body 311 in the direction away from the base main body 311.

The substrate portion 321 is formed with a fixing portion 323 facing the base main body 311. The fixing portion 323 is a through hole that penetrates the substrate portion 321 in the thickness direction of the substrate portion 321.

The base 31 has an insertion portion 314 inserted into the fixed portion 323 and an arm portion 315 provided across the base main body 311 and the insertion portion 314. The base body 311 and the arm portion 315 and the insertion portion 314 are integrally formed with each other. By inserting the insertion portion 314 into the fixing portion 323, the movement of the light emitting substrate 32 with respect to the base body 311 in the slide direction A is restricted. Therefore, the insertion unit 314 constitutes a slide direction regulation unit that regulates the movement of the light emitting substrate 32 with respect to the base body 311 in the slide direction A by being inserted into the fixing unit 323. The position of the fixed portion 323 with respect to the substrate portion 321 in the slide direction A is such that when the insertion portion 314 is inserted into the fixed portion 323, the first claw portion 313A and the second claw portion 313B are respectively on the surface of the light emitting substrate 32. It is in the opposite position. By inserting the insertion portion 314 into the fixing portion 323, the position of the light emitting substrate 32 becomes the mounting position.

The thickness direction dimension L ₁ of the arm portion 315 is less than half of the thickness direction dimension of the base body 311. As a result, the arm portion 315 can be elastically deformed in the thickness direction. When no force is applied to the arm portion 315 in the thickness direction of the base body 311, the insertion portion 314 is arranged outside the base body 311 in the thickness direction of the base body 311. In this case, the insertion portion 314 is inserted into the fixing portion 323. When a force inside the thickness direction of the base body 311 is applied to the arm portion 315, the insertion portion 314 is arranged inside the base body 311 in the thickness direction of the base body 311.

FIG. 6 is a view showing a state in which the light emitting substrate 32 of FIG. 3 is slid with respect to the base 31, and FIG. 7 is a cross-sectional view taken along the line VII-VII of FIG. When attaching the light emitting substrate 32 to the base 31, first, the light emitting substrate 32 is inserted between the first side wall portion 312A and the second side wall portion 312B so that the first claw portion 313A faces the surface of the light emitting substrate 32. do. At this time, the insertion portion 314 hits the back surface of the substrate portion 321. As a result, the insertion portion 314 is pushed inward with respect to the base body 311 in the plate thickness direction.

Then, the light emitting substrate 32 is slid in the sliding direction A with respect to the base 31 until each of the first claw portion 313A and the second claw portion 313B faces the surface of the light emitting substrate 32. As a result, the insertion portion 314 is inserted into the fixing portion 323. As a result, the light emitting substrate 32 is attached to the base 31.

When the light emitting board 32 attached to the base 31 is removed from the base 31, a removal jig that can be inserted into the fixing portion 323 is inserted into the fixing portion 323. Examples of the removal jig include a thin rod that can be inserted into the fixing portion 323. The removal jig is inserted into the fixing portion 323, and the insertion portion 314 is removed from the fixing portion 323 using the removing jig. As a result, the light emitting substrate 32 can slide in the slide direction A with respect to the base 31.

After that, the light emitting substrate 32 is slid with respect to the base 31. When the second claw portion 313B does not face the front surface of the light emitting substrate 32, the insertion portion 314 pushes the back surface of the light emitting substrate 32 by the elastic force of the arm portion 315. As a result, the light emitting substrate 32 is lifted from the surface of the base body 311. After that, the light emitting substrate 32 is removed from the base 31.

As described above, according to the light emitting device 3 of the elevator according to the first embodiment of the present invention, the light emitting substrate 32 is attached to and detached from the base 31 by sliding the light emitting substrate 32 with respect to the base 31. As a result, the light emitting substrate 32 can be attached to and detached from the base 31 without using mounting screws. As a result, the work efficiency of attaching and detaching the light emitting substrate 32 can be improved. Further, since the light emitting board 32 is attached to the base 31, fastening parts such as mounting screws are not required. As a result, the manufacturing cost of the light emitting device 3 of the elevator can be reduced. In addition, the assembly man-hours in the factory can be reduced. As a result, the production cost of the elevator can be reduced.

Further, the base 31 has an arm portion 315 that supports the insertion portion 314, and the arm portion 315 is elastically deformable. As a result, the arm portion 315 is elastically deformed, so that the insertion portion 314 can be moved in and out of the fixed portion 323. As a result, the work of releasing the restraint of the light emitting substrate 32 in the slide direction A becomes easy. Therefore, workability at the site of installation work or the site of maintenance work can be improved. In addition, it is possible to prevent the parts from falling and the parts from being lost at the installation work site or the maintenance work site.

Further, the first claw portion 313A and the second claw portion 313B are arranged so as to be offset from each other in the slide direction A. As a result, either one of the first claw portion 313A and the second claw portion 313B can be made to face the surface of the light emitting substrate 32 first.

Further, when the insertion portion 314 is inserted into the fixing portion 323, each of the first claw portion 313A and the second claw portion 313B faces the surface of the light emitting substrate 32. Further, when the insertion portion 314 is displaced from the fixed portion 323 in the slide direction A, at least one of the first claw portion 313A and the second claw portion 313B is displaced from the surface of the light emitting substrate 32 in the slide direction. They are placed out of alignment. As a result, the light emitting substrate 32 can be securely attached to the base 31 by inserting the insertion portion 314 into the fixing portion 323.
