Detailed Description
An elevator car and an elevator according to an embodiment will be described below with reference to fig. 1 to 9. In the drawings, the same reference numerals are given to the common members.
1. Elevator structure
First, the structure of an elevator according to an embodiment (hereinafter referred to as "this example") will be described with reference to fig. 1. Fig. 1 is a schematic configuration diagram showing a configuration example of an elevator of this example.
As shown in fig. 1, an elevator 1 of this example is provided in a hoistway 110 formed in a building structure. The elevator 1 includes an elevator car 120 that moves up and down in an elevator shaft 110 and carries people and freight, a rope 130, a counterweight 140, and a hoist 100.
The hoist 100 is disposed on the top of the hoistway 110, and winds a rope 130 to raise and lower the elevator car 120. In addition, a diverting pulley 150 on which the hoist rope 130 is suspended is provided near the hoist 100.
The elevator car 120 is attached to one axial end of the suspension rope 130, and the counterweight 140 is attached to the other axial end of the suspension rope 130. Therefore, the elevator car 120 is coupled to the counterweight 140 via the suspension rope 130. When the hoist 100 is driven, the elevator car 120 and the counterweight 140 perform a lifting operation. Hereinafter, the direction in which the elevator car 120 and the counterweight 140 move up and down is referred to as the up-down direction.
[ Elevator cage ]
Next, the structure of the elevator car 120 will be described with reference to fig. 2 to 6. Fig. 2 is a front view showing the interior of the car room of the elevator car 120, and fig. 3 is a plan view of the elevator car 120 as viewed from above in the vertical direction.
As shown in fig. 2, the elevator car 120 has a car room 121, a door unit 122, and the lighting fixture 10. As shown in fig. 1 and 2, the cage 121 is formed in a substantially hollow rectangular parallelepiped shape. The car room 121 is provided with an entrance 124 opened on one side. Then, people and cargoes enter and exit the interior space of the car room 121 through the doorway 124. A door unit 122 is openably and closably provided in the doorway 124.
The car room 121 includes a car floor 127, side plates 126, and a ceiling 125. The car floor 127 is formed in a substantially rectangular shape. A side plate 126 is disposed around the car floor 127. An entrance 124 is formed in one side plate 126 of the side plates 126 surrounding the periphery of the car floor 127.
The ceiling 125 and the car floor 127 face each other in the vertical direction. The ceiling 125 is formed in a substantially rectangular shape similarly to the car floor 127. The ceiling 125 has an opening 3. Further, the lighting fixture 10 is provided on the ceiling 125. The lighting fixture 10 includes a lighting unit and a lighting panel 11, which are not shown. As the illumination unit, various light sources such as a fluorescent lamp, an LED, and an organic EL are applied.
Fig. 3 is a plan view of the opening 3 of the ceiling 125 viewed from above in the vertical direction, and fig. 4 is a plan view of the opening 3 and the illumination panel 11 viewed from above in the vertical direction. As shown in fig. 3, the opening 3 has a substantially elliptical shape. The length L1 of the short axis 3a and the length L2 of the long axis 3b passing through the center of the opening 3 are set to be different lengths. As shown in fig. 4, an illumination panel 11 is provided in the opening 3.
A plurality of (three in this example) holding portions 5 are provided around the opening 3 of the ceiling 125. The holding portion 5 is disposed on the upper surface portion of the ceiling 125 in the vertical direction. The plurality of holding portions 5 are disposed at intervals so as to surround the periphery of the opening 3.
The illumination panel 11 is formed of a member having a light-transmitting property of being transparent or opaque. The illumination panel 11 passes light emitted from an illumination unit, not shown. The illumination panel 11 is formed of a flat plate-like member in a substantially elliptical shape. Therefore, the length L3 of the short axis 11a and the length L4 of the long axis 11b of the lighting panel 11 passing through the center are set to different lengths. The length L3 of the short axis 11a of the illumination panel 11 is set to be shorter than the length L2 of the long axis 3b of the opening 3.
The illumination panel 11 has a substantially elliptical outer surface 12 and a flange 13. The exterior surface portion 12 is formed in a flat plate shape and is disposed in the opening 3. The design surface portion 12 is not limited to a flat plate shape, and may be formed in a dome shape bulging downward in the vertical direction, may be provided with irregularities for diffusing light, or may be formed in other various shapes. A flange portion 13 is continuously formed at the outer edge portion of the appearance surface portion 12.
Fig. 5 is an enlarged perspective view of the outer edge portions of the holding portion 5 and the illumination panel 11. As shown in fig. 5, the flange portion 13 includes a mounting portion 13a and a side surface portion 13 b. The mounting portion 13a is formed continuously from the outer edge portion of the exterior surface portion 12. The external appearance surface portion 12 protrudes downward in the vertical direction from the placement portion 13 a. The mounting portion 13a is mounted on the upper surface portion in the vertical direction of the outer edge portion of the opening 3 (see fig. 8).
This can close the gap between the opening 3 and the illumination panel 11. As a result, the ceiling 125 can be prevented from being viewed from the opening 3 in the car chamber 121 upward in the vertical direction, and the appearance of the elevator car 120 can be prevented from being impaired.
The side surface portion 13b is continuous substantially perpendicularly from an end portion of the mounting portion 13a on the side opposite to the external appearance surface portion 12. The side surface portion 13b protrudes upward in the vertical direction from an end of the mounting portion 13 a. The side surface portion 13b is continuously curved along the circumferential direction of the illumination panel 11. The holding portion 5 contacts the side surface portion 13 b.
The holding portion 5 is fixed to a member 125a such as a rib or a ridge provided on the ceiling 125 via a fixing screw 8. The holding portion 5 is formed of a flat plate-like member. The holding portion 5 is a plate spring provided with elasticity by bending a flat plate-shaped member. The plurality of holding portions 5 press the flange portion 13 of the illumination panel 11 toward one side, and hold the illumination panel 11.
This prevents the illumination panel 11 from being displaced or detached due to vibration generated when the elevator car 120 moves up and down. Further, the illumination panel 11 can be held without using a magnet, a fastening member, or the like. As a result, the number of components can be reduced, and the lighting panel 11 does not need to be processed.
The holding portion 5 includes a pressing portion 5a, a fixing portion 5b, and a connecting portion 5 c. The pressing portion 5a contacts the side surface portion 13b of the flange portion 13 of the illumination panel 11. In addition, a stopper 6 is provided on the pressing portion 5 a.
The stopper 6 is a protrusion protruding from a surface of the pressing portion 5a that contacts the side surface portion 13 b. As the stopper 6, a screw, a pin, or the like can be used. The stopper 6 faces the upper end of the side surface portion 13b in the vertical direction. When the illumination panel 11 is floated upward in the vertical direction, the side surface portion 13b abuts against the stopper 6.
A connecting portion 5c is continuously formed at an end of the pressing portion 5 a. The connecting portion between the pressing portion 5a and the connecting portion 5c is bent. A fixing portion 5b is continuously formed at an end of the connecting portion 5c opposite to the pressing portion 5 a. The connecting portion 5c and the fixing portion 5b are bent at their connecting portions. The fixing portion 5b is fixed to the member 125a of the ceiling 125 via a fixing screw 8.
In this example, although a plate spring is used as the holding portion 5, the present invention is not limited to this, and other various elastic members such as a coil spring and rubber may be used as the holding portion 5. In the case of the plate spring, elasticity can be easily imparted by folding a flat plate-like member. Therefore, the holding portion 5 can be manufactured at a lower cost using a plate spring than using a coil spring, rubber, or the like, and can be easily fixed to the member 125a of the ceiling 125.
The number of the holding portions 5 is not limited to three, and two or four or more holding portions 5 may be provided.
2. Example of installation work of illumination Panel
Next, the operation of installing the illumination panel 11 of the elevator car 120 having the above-described configuration will be described with reference to fig. 6 a to 9. Fig. 6 a to C are sectional views showing the installation work of the illumination panel 11, and fig. 7 a to C are plan views showing the installation work of the illumination panel 11.
First, as shown in fig. 6 a, the operator inserts the illumination panel 11 obliquely from inside the car room 121 into the opening 3 of the ceiling 125. Here, the length L3 of the short axis 11a of the illumination panel 11 is set to be shorter than the length L2 of the long axis 3b of the opening 3. Therefore, the illumination panel 11 can be inserted into the opening 3 by orienting the short axis 11a of the illumination panel 11 to the long axis 3b of the opening 3. On the other hand, when the illumination panel and the opening are formed in a circular shape, the illumination panel cannot be inserted into the opening from the inside of the car room 121 because the distances from the center are completely equal.
As shown in fig. 6B, when the illumination panel 11 is completely inserted from the opening 3 to above the ceiling 125, the illumination panel 11 is placed on the outer edge portion of the opening 3. Then, as shown in B of fig. 7, the illumination panel 11 is rotated so that the short axis 11a of the illumination panel 11 coincides with the short axis 3a of the opening 3 and the long axis 11B of the illumination panel 11 coincides with the long axis 3B of the opening 3, as shown in C of fig. 7.
Thereby, as shown in fig. 8, the placement portion 13a of the flange portion 13 of the illumination panel 11 is placed on the outer edge portion of the opening portion 3 of the ceiling 125. The appearance surface 12 of the illumination panel 11 is fitted into the opening 3.
As shown in fig. 9, the side surface portion 13b of the flange portion 13 of the illumination panel 11 is in contact with the pressing portion 5a of the holding portion 5. The illumination panel 11 is pressed and held by the plurality of holding portions 5. As described above, the illumination panel 11 is formed in a substantially elliptical shape, and the side surface portions 13b are continuously curved. Therefore, even when the position of the illumination panel 11 is slightly shifted, the pressing portion 5a of the holding portion 5 can be brought into contact with the side surface portion 13 b. This enables the illumination panel 11 to be reliably held by the plurality of holding portions 5.
A plurality of holding portions 5 are arranged at intervals around the opening 3. Therefore, the illumination panel 11 is pressed from a plurality of directions by the plurality of holding portions 5. This prevents the illumination panel 11 from being displaced or dropped due to vibration generated in the car room 121.
The stopper 6 is disposed above the side surface portion 13b of the flange portion 13 in the vertical direction. That is, the side surface portion 13b is disposed between the stopper 6 and the outer edge portion of the opening 3. This prevents the illumination panel 11 from floating upward in the vertical direction.
When the lighting panel 11 is removed from the ceiling 125 during maintenance and inspection of the lighting fixture 10, the lighting panel 11 is rotated from the car room 121 to a position where the long axis 11b does not coincide with the long axis 3b of the opening 3. Then, as shown in fig. 6 a and B, the illumination panel 11 is tilted, and the illumination panel 11 is taken out from the opening 3.
As described above, according to the elevator car 120 of the present example, the installation work and the removal work of the illumination panel 11 can be performed from the car room 121. Further, by providing the stopper 6, the illumination panel 11 can be prevented from floating when the illumination panel 11 is tilted.
The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the claims.
In the present specification, terms such as "parallel" and "orthogonal" are used, but they mean not only strictly "parallel" and "orthogonal" but also "substantially parallel" and "substantially orthogonal" within a range in which they can function.
