Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator emergency light device for illuminating the inside of an elevator car during a power failure.

[0002]

[Prior Art]

 As shown in Fig. 5, a milky white synthetic resin ceiling panel 101 is attached to the ceiling of a conventional car, and the top wall surface above the ceiling panel 101 illuminates the inside of the car 102 brightly. A plurality of circular fluorescent lamps 103 are provided, and an emergency lamp 104 for illuminating the inside of the car 102 at the time of power failure is provided next to the fluorescent lamps 103. In recent years, there has been a demand for the ceiling panel 101 to be luxurious inside the car 102. Therefore, various designs are required, and the interior of the car 102 is illuminated through the ceiling panel 101.

[0003]

[Problems to be solved by the device]

 However, in such a conventional emergency light 104, since it is provided on the top wall surface above the ceiling panel 101, the interior of the car 102 is illuminated to illuminate the inside of the car 102 during a power failure. Here, since the ceiling panel 101 has various designs, it has become thick. For this reason, when the interior of the car 102 was illuminated by the emergency light 104 provided on the top wall of the car, the illuminance inside the car 102 was low due to the thickened Arai panel 101. However, since the illuminance in the car 102 by the emergency light 104 is legally determined to be equal to or higher than a certain reference value, a predetermined illuminance is necessary. In order to secure this predetermined illuminance, the emergency light 104 Must have a high luminous intensity, that is, be large. Therefore, using such a large emergency light will increase the cost, increase the storage space when installing it on the top wall of the car, and consume more emergency power. There was a point.

An object of the present invention is to provide an emergency lighting device for an elevator, which reduces costs, reduces a storage space, and reduces consumption of an emergency power source.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, according to the present invention, a fitting hole formed in a car of an elevator and a detachable fitting hole in the fitting hole are rotatably attached to the car. An attached support plate, an emergency light provided on the inner side surface of the support plate to illuminate the inside of the car in the event of a power failure, and the support plate is rotated from the fitted state to expose the inner side surface. It is configured to include such a driving means.

[0006]

[Action]

 At the time of power failure, the supporting plate fitted in the fitting hole is rotated by the driving means to expose the inner side surface of the supporting plate, so that the emergency light can directly illuminate the inside of the car.

[0007]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. 1 to 4 are views showing an embodiment of an emergency light device for an elevator according to the present invention.

In FIG. 1, reference numeral 1 is an elevator car that can move vertically in a hoistway 2 in a building. The car 1 has a bottom surface 3, side walls 4, a ceiling 5, a fascia 6 and the like. There is. A ceiling panel 7 made of milky white and made of synthetic resin is attached to the ceiling 5, and a top wall surface above the ceiling panel 7 is provided with a circle-line fluorescent lamp 8 for illuminating the inside of the car 1. An entrance 9 is provided in the car 1, and a fascia 6 is located above the entrance 9.

As shown in FIGS. 2 and 3, the fascia 6 includes an inner part 6 a located inside the car 1, a bottom part 6 b located above the entrance 9, and a bent part bent outside the car 1. 6c, and a hole 10 for fitting is formed in the bottom portion 6b. A support plate 11 is removably fitted into the fitting hole 10, that is, the base end side of the support plate 11 is rotatably attached to the bottom portion 6b via a support pin 12, and the tip end side Is swingable. A rising plate portion 11 a is vertically formed from the base end side of the support plate 11 and is integrally formed. An emergency light 13 made of a fluorescent lamp is provided on the inner surface 11b of the support plate 11, and an electric current is supplied to the emergency light 13 from a rechargeable emergency power source (battery). Further, the support plate 11 is provided with a rack 14 which is substantially arcuate in its entirety and has teeth formed inside thereof.

A pinion 15 meshes with the rack 14, and the pinion 15 is attached to a drive shaft of a motor 16 (driving means) provided on the bottom portion 6 b of the fascia 6. When the motor 16 is driven, the support plate 11 is rotated via the pinion 15 and the rack 14. The limit switch 17 for detecting that the emergency light 13 is exposed by the rotation of the support plate 11 has a bottom portion 6b. A limit switch 18 for detecting that the emergency light 13 is housed in the fitting hole 10 by being rotated on the other hand is provided in the bent portion 6c.

Next, FIG. 4 shows an electric circuit that drives the motor 16 to turn on the emergency light 13 in the event of a power failure. In the figure, reference numeral 19 is an emergency power source for supplying a current to the motor 16 at the time of power failure. A commutator 22 is provided between them. The current from the emergency power source 19 is supplied to the motor 16 via NC type limit switches S ₁ , S ₂ , 17, 18 and a ₁ , a ₂ , b ₁ , b ₂ contacts 23, 24, 25, 26. It is also supplied to the emergency light 13 via the b ₃ contact 27 and the DC / AC converter 28. The a ₁ , a ₂ , b ₁ , b ₂ , b ₃ contacts 23, 24, 25, 26, 27 are opened and closed by a relay circuit 29.

When a power failure occurs during the operation of the elevator, the relay circuit 29 is de-energized, the a ₁ , a ₂ contacts 23, 24 are changed from the closed state to the open state, and the b ₁ , b ₂ , b ₃ contacts are made. The points 25, 26, and 27 change from the open state to the closed state. Here, since the limit switches S ₁ , S ₂ , 17, and 18 are in the closed state, a current is supplied to the motor 16 from the emergency power source 19 as shown by the solid line in FIG. 4, and the emergency light 13 is turned on. . By the normal rotation of the motor 16, the support plate 11 rotates about the support pin 12 (removed from the fitting hole 10), and the inner side surface 11 b is exposed in the car 1. When the support plate 11 is rotated and the rising plate portion 11a comes into contact with the limit switches S ₁ and 17, the limit switches S ₁ and 17 are changed from the closed state to the open state, and the motor 16 receives the emergency power supply 19 from Current stops flowing and the drive stops. At this time, the support plate 11 is in a vertical state, and the emergency light 13 is completely exposed to directly illuminate the inside of the car 1 without passing through the ceiling panel as in the conventional case. Therefore, the emergency light 13 may have a relatively low luminous intensity, that is, a small size, in order to obtain a predetermined illuminance in the car 1.

Next, when the power failure state is resolved, the relay circuit 29 is excited and a₁, A₂The contacts 23 and 24 change from the open state to the closed state, and b₁, B₂, B₃The contacts 25, 26, 27 change from the closed state to the open state, a current flows from the emergency power source 19 as shown by the broken line in FIG. 4, the emergency light 13 is turned off, and the motor 16 is rotated in the reverse direction. The support plate 11 is rotated to be housed in the fitting hole 10, and the rising plate portion 11a has the limit switch S. ₂ The reverse rotation of the motor 16 is stopped by contacting the motor 18.

An electromagnet or the like may be used as the driving means, or the latch may be manually removed.

[Effect of the device]

 As described above, according to the present invention, in the event of a power failure, the support plate fitted in the fitting hole is rotated by the drive means to expose the inner surface of the support plate. Can be illuminated. Therefore, it is possible to use a small-sized emergency light, which in turn can reduce the cost, reduce the storage space, and reduce the consumption of the emergency power supply.
