  The duct connects the cooler installed on the car and the car interior. In order to arrange the lighting as widely as possible on the entire ceiling surface, it is preferable that the duct is arranged as close to the outer edge of the car as possible and the duct thickness is small. For this reason, the duct is arranged as close to the outer edge of the car as possible, and the air passage is made smaller in the lower part (inside the car cabin) than in the upper part (cooler side). Those oriented inward from the outer edge of the car are preferred (see FIG. 1 of Patent Document 1).

  For ducts that are oriented so that they extend to the inside of the car, depending on whether they are attached to the inner surface or the outer surface of the ceiling frame, the position of the mounting parts such as the screw receiving members and screw holes of the duct and the duct Duct components could not be shared because the relationship with the spreading direction was reversed.

  An object of the present invention is to provide a technique that enables a duct component to be shared by a plurality of ceiling frames having different duct mounting structures.

  ADVANTAGE OF THE INVENTION According to this invention, a duct component can be shared by several ceiling housings from which a duct attachment structure differs.

It is a schematic diagram of an example of an elevator by this embodiment. It is the figure which looked at the passenger car 1 from the upper side. It is AA 'sectional drawing of the elevator car 1 as an example. It is AA 'sectional drawing of the cage | basket | car 1 upper part in another example. It is the figure which looked at the 1st duct member 10 attached to the ceiling housing 8 in FIG. 2 and FIG. 3A from the B direction.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic view of an example of an elevator according to the present embodiment. The elevator according to the present embodiment is configured to raise and lower the car 1 by hoisting a rope connecting the car 1 and the counterweight 2 at both ends by the hoisting machine 3. The car 1 has a car body 1a and a ceiling housing 8, and the ceiling housing 8 is placed on the car body 1a.

  The upper part of the car body 1a is open, and the opening of the upper part of the car body 1a is blocked by the ceiling casing 8 being placed thereon. The ceiling housing 8 is a duct (not shown), and an air flow path is formed between the upper portion of the car 1 and the room.

  FIG. 2 is a view of the car 1 as viewed from above. In FIG. 2, there are two ducts at the top and bottom in the figure. One end of the air ducts 5a and 5b is connected to the upper opening of the duct, and the gap between the duct and the air ducts 5a and 5b is closed by the duct covers 6 and 7. The other ends of the blower pipes 5 a and 5 b are both connected to the cooler body 4.

  FIG. 3A is an AA ′ cross-sectional view of the upper portion of the car 1 as an example. FIG. 3B is a cross-sectional view taken along the line AA ′ of the upper portion of the car 1 in another example.

  Referring to FIG. 3A, the duct 15 includes a first duct member 10 and a second duct member 16. The first duct member 10 can be attached to the outer surface of the ceiling housing 8 when the attachment portion 10a faces inward, and can be attached to the inner surface of the ceiling housing 8 when the attachment portion 10a faces outward.

  FIG. 3A shows an example in which the attachment portion 10a is directed inward (right side in the drawing) and attached to the outer surface of the ceiling casing 8 from the outside. On the other hand, FIG. 3B shows an example in which the attachment portion 10a is directed outward (left side in the drawing) and attached to the outer surface of the ceiling casing 8 from the outside. Whether the mounting portion 10a is directed inward or outward can be selected according to the structure of the ceiling casing 8. The first duct member 10 forms an air flow path between the interior of the car 1 and the upper part of the car when attached to the ceiling housing 8. And the horizontal cross-sectional shape of the air flow path is a rectangle.

  The second duct member 16 has a lower small opening corresponding to the upper opening of the first duct member 10 in at least two connection methods, and an upper large opening larger than the lower small opening, and the lower small opening and the upper large opening. It has at least one vertical plane on the side of the air flow path between the openings. In the present embodiment, as shown in FIGS. 3A and 3B, the first duct member 10 is directed inward (see FIG. 3A and FIG. 3B) in the state in which the mounting portion 10 a faces the inside or the outside. It can connect with the 1st duct member 10 so that it may face toward the inside right side.

  In the example of FIG. 3A, a state in which the lower small opening of the second duct member 16 is connected to the upper opening of the first duct member 10 with the attachment portion 10a facing inward is shown. The vertical plane of the second duct member 16 faces outward. On the other hand, in the example of FIG. 3B, the vertical plane of the second duct member 16 faces outward in a state where the attachment portion 10a is directed outward.

  According to the present embodiment, by selecting the mounting direction of the first duct member 10, the second duct member 16 can be mounted from the outside or the inside of the ceiling casing 8 and the upper portion of the second duct member 16 is widened. Therefore, the first duct member 10 and the second duct member 16 can be shared by two ceiling housings 8 having different mounting structures.

  Moreover, the illumination light source 14 is arrange | positioned inside the ceiling housing | casing 8, and the 1st duct member 10 is a direction (left-right direction in a figure) orthogonal to the outer surface of the ceiling housing 8 of an air flow path from upper opening to lower opening. The thickness is constant. The first duct member 10 whose cross section is on the side of the ceiling housing 8 has a constant thickness and is spread by the second duct member 16 connected to the upper portion thereof. The illumination light source 14 can be widely arranged over the entire ceiling. In the present embodiment, condensation is prevented by disposing the heat insulating material 13 between the first duct member 10 that is at a low temperature and the illumination light source 14 that is at a high temperature.

  The height of the first duct member 10 is selected according to the height of the ceiling casing 8. In the example of FIGS. 3A and 3B, the height of the first duct member 10 is substantially the same as the height of the ceiling casing 8. It can respond to the ceiling housing 8 of various heights only by changing the height of the 1st duct member 10, and the 2nd duct member 16 can be shared.

  In the second duct member 16, the expansion of the air flow path from the lower small opening to the upper large opening is directed to the inside of the car 1. Thereby, it is possible to make the duct wide in the upward direction while keeping the duct within the range of the car 1.

  The second duct member 16 changes the shape of the openings of the blow pipes 5a and 5b so as to match the upper and lower openings of the first duct member 10 that are outlets for blowing cool air. Therefore, the lower small opening of the second duct member 16 is narrowed smaller than the upper large opening. Since the 2nd duct member 16 is arrange | positioned above the ceiling housing 8, the ceiling housing 8 can be taken widely and the illumination light source 14 can be arrange | positioned widely. Moreover, even when the ceiling casing 8 has irregularities in the vertical direction for the purpose of a design effect, it is possible to prevent the ceiling casing 8 and the duct from interfering with each other. For example, even when a semi-transparent acrylic shielding plate that forms the lower surface of the ceiling housing 8 and allows light from the illumination light source 14 to have an arch shape, the shielding plate can be prevented from interfering with the duct. .

  Moreover, in this embodiment, in order to prevent dew, the heat insulating material 13 is affixed to the ceiling casing 8 that is a lighting fixture mounting portion, but the first duct member 10 that is a cold wind tunnel plate is used as the outside of the ceiling casing 8. Therefore, the illumination light source 14 can be disposed in the vicinity of the end of the ceiling, and the light from the illumination light source 14 is less likely to be disturbed. As a result, the design of the ceiling, such as the occurrence of light unevenness, is prevented from being impaired.

  FIG. 4 is a view of the first duct member 10 attached to the ceiling casing 8 in FIGS. 2 and 3A as viewed from the B direction. Referring to FIG. 4, the first duct member 10 is fixed to the ceiling housing 8 with bolts 12 in the attachment portion 10 a. Even if the height 11 of the ceiling casing 8 is changed, the height of the first duct member 10 is changed so that the change of the height of the ceiling casing 8 is shared by the second duct member 16. be able to. For this reason, until now, each of the cooler ducts has been attached to the ceilings having different ceiling casing heights. However, by making the structure common, it is possible to improve the assembly workability.

  The above-described embodiments of the present invention are examples for explaining the present invention, and are not intended to limit the scope of the present invention only to those embodiments. Those skilled in the art can implement the present invention in various other modes without departing from the spirit of the present invention.
