Abstract

PURPOSE:To prevent an accident of fall or the like of mankind and things by automatically closing a hole of a lift path generated in an upper story floor surface when an cage of an elevator, which is lifted between upper and lower stories, is lowered down. CONSTITUTION:A roof of a cage 2 is supported by a plurality of pantographic struts to constitute a movable roof further with this movable roof plate left as made larger than a hole 5 of a lift path in an upper story floor surface, and when the cage 2 is lowered down, the hole 5 of the lift path is automatically closed to prevent an accident of fall into the hole 5.

Description

[Detailed description of the invention]

[Object of the invention]

0002

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator that ascends and descends between two floors.

0003

[Prior Art] Raised elevators, in which the car is raised and lowered between the upper and lower floors using a pantograph, are installed and used in helipads on the roofs of buildings where it is not possible to install a machine room above the hoistway, backstage of theaters, etc. .

[0004] As in the case of general elevators, the car in such an elevator is integrally constructed by having a ceiling attached to the upper part of a side plate which is constructed by providing a steel plate or a stainless steel panel around the car floor. In addition, when the car descends to the lower floor, the hoistway remains open on the floor of the upper floor, so handrails or the like are usually installed around the hoistway hole to prevent falls. has been established.

[0005]

[Problems to be Solved by the Invention] In such a raised elevator, when the car descends from the upper floor to the lower floor, a hole for the hoistway is left open in the upper floor. Therefore, a handrail of a protective fence should be installed around this hole. However, there is always a risk of accidents such as people or objects accidentally falling or falling.

The present invention solves the above problem by automatically closing holes in the hoistway on the upper floor surface that occur when the car is lowering or while waiting on the lower floor, thereby preventing accidents such as falls. It is intended to.

[Configuration of the invention]

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a movable ceiling structure in which the ceiling of an elevator car is supported by a plunger cylinder-shaped extensible column, and a hoistway that is opened to the upper floor. Attach the edge fittings around the hole,
Make the ceiling of the car larger than this hole, and cover the hole (opening) for the hoistway in the upper floor with the ceiling board.

[0009]

[Operation] When a car with this structure starts to descend from the upper floor, the outer edge of the movable ceiling board hits the edge fittings attached to the upper floor, the movable ceiling board stops at the upper floor, and the upper floor is suspended. close the hole.

Furthermore, the car ceiling side support that is attached to the movable ceiling board slides within the car floor support and the support extends, and the car that is separated from the movable ceiling board immediately descends and reaches the lower floor. .

As mentioned above, the movable ceiling plate closes the hole in the hoistway and becomes flat by being integrated with the floor on the upper floor, so there is no chance of people or objects falling through the hole in the hoistway on the upper floor. Prevent accidents.

[0012] When the car is raised from the lower floor to the upper floor, when the car is raised, the support on the car ceiling side attached to the movable ceiling board slides within the support on the car floor side, and the support is shortened. When the support on the floor side of the car hits the lower surface of the movable ceiling board, the ceiling is immediately pushed up, and the car reaches the upper floor.

[0013]

EXAMPLE The present invention will be explained using the example shown in FIGS. 1 and 2.

[0014] The car 2 of the lift type elevator, which ascends and descends from floor to floor by means of a pantograph 1, etc., is constructed as follows.

The car 2 is formed by a car floor 3 and a side plate (not shown) fixed around the car floor 3, and a movable ceiling plate 4 is placed on top. The size of the movable ceiling plate 4 is the hole in the upper floor (hole for hoistway)
Make it larger than 5.

The movable ceiling plate 4 is supported by a plurality of pillars provided separately from the side plates. That is, the floor side supports 7, 7... of the plunger cylinder type support 6 are provided on the car floor 3, the plunger type ceiling plate mounting supports 8, 8... are fixed to the lower surface of the movable ceiling plate 4, and the movable ceiling plate The mounting struts 8, 8... are fitted into the car floor mounting struts 7, 7..., respectively, and are configured to be expandable and contractible.

Furthermore, an edge fitting 9 is attached around the hole of the hoistway on the upper floor surface.

When the elevator car 2 constructed as described above begins to descend from the upper floor to the lower floor, the movable ceiling plate 4 hits the edge fittings 9 around the hole in the hoistway on the upper floor and is blocked from descending. It stops when it is on the same level as the surface. The movable ceiling board mounting supports 8, 8, fixed to the lower surface of the movable ceiling board 4 slide inside the car floor mounting supports 7, 7, and extend to support the movable ceiling board 4, and the car 2 is lowered and lowered. Reach the floor. On the other hand, when the car 2 rises from the lower floor to the upper floor, the movable car ceiling plate mounting supports 8, among the car floor mounting supports 7, 7, provided on the car floor 3,
8 slide, the support column 6 shortens, rises together with the car floor 3, hits the movable car ceiling plate 4, and raises the car 2 to the upper floor.

As mentioned above, when the elevator descends, the floor surface of the upper floor is flattened by the movable ceiling plate and the hole in the hoistway is covered, thereby preventing accidents such as falling from the hole. Can be done.

[0020]

[Effects of the Invention] According to the present invention, when the car of the raised elevator that goes up and down the upper and lower floors descends, the movable ceiling plate automatically closes the holes in the hoistway on the floor of the upper floor. This will prevent accidents such as falling into the hole.
