I have. The three-way frame 4 is configured by connecting two vertical frames 7 each having a substantially U-shaped cross-section formed by sheet metal bending or the like, and a similar horizontal frame 8 in a gate shape. This is a framed structure. An elevator hall lantern 9 is provided on the upper part of the vertical frame 7 of the three-way frame 4 to notify passengers of the hall 2 of the arrival of the car by lighting.

  As shown in FIG. 2, the hall lantern 9 of the elevator cuts a part of the vertical frame 7 of the three-way frame 4 to form an opening 10, and is a light-transmitting opening / closing attached by a hinge 11 so that the opening 10 can be opened / closed. A panel 12, a light source 13 such as an LED or a lamp that is disposed inside the vertical frame 7 and irradiates the opening / closing panel 12, and a locking device 14 that holds the opening / closing panel 12 in a closed position with respect to the three-way frame 4 are provided. ing. The open / close panel 12 includes a panel main body 15 formed by sheet metal bending connected to the vertical frame 7 of the three-way frame 4 by a hinge 11 and a translucent acrylic attached so as to be fitted into a notch portion of the panel main body 15. And a light transmissive lens 16 such as a block. Between the vertical frame 7 of the three-way frame 4 and the open / close panel 12, as shown in FIG. 3, a hinge portion gap 17 for making the hinge 11 movable is provided.

  The opening / closing panel 12 and the hinge 11 are not opened on the landing 2 side, that is, on the side of the hoistway that is difficult to access, but on the side where an operator can easily perform opening / closing work and subsequent maintenance / inspection work from the landing 2 side. Further, the three-way frame 4 is arranged on the side of the vertical frame 7 facing the landing 2. In the illustrated example, it is provided on a surface forming the entrance / exit 3 of the three-way frame 4 in a direction perpendicular to the wall 1 of the building, but may be provided on a surface parallel to the wall 1 of the building. Therefore, the gap 17 between the vertical frame 7 and the open / close panel 12 is also on the hall 2 side of the vertical frame 7, and the locking device 14 is moved from the hall 2 side by a tool 18 such as an unlocking rod that can be inserted through this gap. It can be opened.

  As shown in detail in FIGS. 3 to 5, the vertical frame 7 to which the hall lantern 9 of the elevator is attached is attached to fixed plates 19 and 20 fixed to the wall 1 of the building. A closing plate 21 is provided at a position corresponding to the opening 10 inside the vertical frame 7, that is, a position facing the opening / closing panel 12. The closing plate 21 is attached to the closing plate 21 so as to be rotatable around a pin 22. A lever 24 that is always biased to the locking position by 23 is provided. The lever 24 is provided by an engagement end 26 that engages with a hook 25 of the opening / closing panel 12 when the opening / closing panel 12 is in the closed position of FIG. 3, and a tool 18 that can be inserted through the gap 17 of the hinge portion as shown in FIG. And an operating end 27 to be opened.

  A permanent magnet 28 is attached to the inner surface of the closing plate 21 attached to the fixed plate 19 fixed to the wall 1 of the building, on the side far from the hinge 11, and the open / close panel 12 is held in the closed position by magnetic attraction. I can do it. The holding by the permanent magnet 28 can eliminate rattling of the open / close panel 12. Instead of the permanent magnet 28, an adhesive band can be used in which two tape-like sheet members each having a large number of elastic engagement pieces implanted therein are pressed against each other so that the engagement pieces are intertwined with each other. .

  The light-transmitting lens 16 fitted from the inside into a notch provided in the panel body 15 of the open / close panel 12 is a bolt with its outer surface parallel to the surface of the panel body 15 facing the landing 2 but slightly protruding. It is fixed to the inner surface of the panel main body 12 by a fastener 29 such as. Thus, the outer surface of the light transmissive lens 16 constitutes a part of the surface of the panel body 15.

  The inner surface of the panel main body 12 is also formed by sheet metal processing, and includes a partition wall 30 that rises from the panel main body 15 and an opening / closing lid 32 that is rotatably attached to the partition wall 30 by a hinge 31. Part 33 is attached. Further, a support bracket 34 for supporting the light source 13 at a position facing the light incident surface side of the light transmissive lens 16 is attached to the inner surface of the opening / closing lid 32, and the opening / closing lid 32 is as shown in FIGS. When the light source 13 is in the closed position with respect to the open / close panel 12, the light source 13 is an irradiation position for irradiating the light incident surface of the light transmissive lens 16, and when the light source 13 is in the open position as shown in FIG. The deployment position is moved to an access position that can be easily accessed from the hall 2 side. The opening / closing lid 32 is provided with a fastener 35 such as a set screw or a permanent magnet that is screw-engaged with the partition wall 30 to hold the opening / closing lid 32 when the opening / closing lid 32 is in the closed position.

  In such an elevator hall lantern, normal operation of the elevator can be performed in the state shown in FIG. In this case, there is no need for a gap for inserting the unlocking tool 18 between the building wall 1 and the three-sided frame 4, it is not affected by the construction situation of the building, and the degree of freedom in design is high. High and excellent aesthetic treatment can be performed. In addition, the gap 17 for inserting the unlocking tool 18 together with the open / close panel 12 and the hinge 11 makes the open / close panel 12 easy to open and close, and subsequent maintenance and inspection from the landing 2 side. Since it is configured to open to the side where work can be performed, for example, it is not necessary to perform work using a stepladder in the elevator pit, and work time and labor can be greatly reduced.

  That is, in FIG. 3, the open / close lid 32 that supports the light source 13 is held by the fasteners 35 on the partition wall 30 and is in the closed position with respect to the open / close panel 12, and the light source 13 irradiates the translucent lens 16. It is placed at an irradiation position where it can be notified that the hall 2 is lit. The open / close panel 12 is in the closed position, and the engagement end 26 of the lever 24 of the locking device 14 is engaged with the hook 25 of the panel body 15 by the spring 23 to hold the open / close panel 12 in the closed position. . The permanent magnet 28 also holds the open / close panel 12 in the closed position by the magnetic attractive force.

  In such an elevator hall lantern, when performing maintenance work such as replacement of the light source 13, a tool 18 such as an unlocking rod is placed between the vertical frame 7 and the panel body 15 as indicated by an imaginary line in FIG. 3. It is inserted through the gap 17 of the formed hinge part and engaged with the operating end 27 of the lever 24 of the locking device 14, and the lever 24 is rotated around the pin 22 against the spring action of the spring 23 and engaged. The end 26 is removed from the hook 25 to release the open / close panel 12 from mechanical restraint. Next, around the hinge 11, the open / close panel 12 is rotated by hand against the magnetic attraction force of the permanent magnet 28 to the open position as shown in FIG. Next, when the fastener 35 is loosened and the opening / closing lid 32 is rotated around the hinge 31, the light source 13 is in a deployed position protruding toward the landing 2 as shown in FIG. 5. At this unfolded position, maintenance inspection of equipment such as the light source 13 can be easily performed from the landing 2.

  In the hall lantern of the elevator, the opening / closing operation of the locking device 14 can be easily performed from the landing 2 side by the tool 18 that can be inserted through the gap 10 between the three-way frame 4 and the opening / closing panel 12. Since this gap 10 uses a gap necessary for opening and closing the hinge 11 provided in the hinge portion, it is not necessary to provide an extra gap that is not preferable in design. Further, since the opening / closing panel 12 is held in the closed position by the permanent magnet 28 in addition to the locking device 14, this portion does not rattle the vertical frame 7. The light source 13 is attached to the open / close panel 12, is movable with respect to the open / close panel 12, and can be deployed at an irradiation position for irradiating the light transmissive lens 16 and an unfolded position convenient for maintenance and inspection. And can be done quickly.
