Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an entrance and exit of an elevator used for an intermediate seismic isolation building.

[0002]

2. Description of the Related Art In an intermediate seismic isolation building, a relative displacement of about 250 mm occurs in the horizontal direction between the upper floor and the lower floor of the seismic isolation mechanism, and therefore, the elevator must be able to cope with it. However, in the conventional elevator, the guide rail for guiding the elevator cage is fixed to the elevator shaft, and therefore, the guide rail is deformed with the relative displacement of the upper and lower floors, and its range exceeds the elastic range. Plastic deformation, and the guide roller may come off.

Therefore, it is conceivable that the guide rails supported by the upper floor and the lower floor are supported with a certain degree of freedom to cope with the displacement. However, if the guide rails have a degree of freedom in this way, the relative positions of the cage and the entrance will be misaligned, making entry and exit difficult or dangerous when entering and exiting. Becomes

[0004] For example, Japanese Patent Application Laid-Open No. 9-278314 proposes an elevator in which a guide rail is mounted via a sliding support device and operates so that the guide rail does not follow the displacement of the building. However, in this technique, no consideration is given to the handling of the entrance due to the displacement of the guide rail.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to an elevator used for an intermediate seismic isolation building, which is provided between a cage and an entrance when a method of supporting guide rails in upper and lower layers has a degree of freedom. It is an object of the present invention to provide a structure of an entrance and exit of an elevator for an intermediate seismic isolation building which does not cause difficulty or danger in entering and exiting in response to a relative displacement.

[0006]

According to the present invention, in a structure of an entrance and exit of an elevator used for an intermediate seismic isolation building, a guide rail for guiding an elevator car is supported by a bracket so as to be displaceable in a horizontal direction, and an entrance and exit on the building side. And a frame supporting the external door is configured to be movable in the horizontal direction in the elevator shaft, and a connecting member for connecting the frame and the guide rail is provided so that the frame follows the displacement of the guide rail. It is configured so that the floor plate at the entrance on the building side can follow the displacement of the frame.

Therefore, according to the present invention, when the seismic isolation mechanism of the intermediate seismic isolation building acts and a relative displacement occurs between the upper and lower stories of the seismic isolation mechanism, the guide rails are horizontally moved by the bracket. Since it can be displaced, it is gently elastically deformed. The relative displacement between the cage and the building-side entrance due to the deformation of the guide rail is such that the frame supporting the external door follows the displacement of the guide rail by the connecting member, and the floor plate at the entrance is also connected by the connecting member. Since they are connected and follow the frame, there is no gap, and the elevator can be moved in and out without any trouble.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a bracket 10 is fixed to a wall surface 12 of an elevator shaft S, and a guide rail 11 extending vertically in the shaft S can be displaced with respect to a horizontal direction at a distal end portion thereof via a link mechanism described later. It is supported by.

The elevator car 13 having the inner door 15 is guided by the guide rails 11 by a plurality of guide arms 20 fixed to the side surface thereof, and is provided to be vertically movable.

The frame 30 forming the entrance G on the building side is
The interior of the elevator shaft S is provided so as to be displaceable in the horizontal direction, and the exterior door 31 is supported therein. One end of a connection arm 33 (see FIG. 3) formed of a diamond-shaped panda graph in which a spring is inserted is fixed to both side surfaces of the frame body 30, and the connection arm 33 is connected to a connection member in a direction perpendicular thereto. 32 is connected to the guide rail 11 side.

Therefore, the frame 30 is connected to the guide rail 11.
And the relative position between the inner door 15 of the cage 13 and the outer door 31 of the frame 30 facing the same is kept constant.

A floor plate 36 having one end fixed to the frame 30 has the other end inserted slidably in the horizontal direction indicated by an arrow X below the building-side floor surface 37. It is configured such that there is no gap with the building-side floor surface due to the displacement of the frame 30.

FIGS. 2 and 3 show details of the bracket 10 for supporting the guide rail 11 and the guide arm 20 for guiding the cage 13 along the guide rail 11. The bracket 10 includes a mounting member 1 fixed to a shaft wall 12, a pair of support arms 3 </ b> A and 3 </ b> B locked in a long hole 1 a on the upper surface thereof, and the support arm 3.
The guide rails 11 are pivotally attached to the tips of A and 3B with pins 4.
And a supporting member 5 for supporting the above. The support arms 3A and 3B are formed in a triangular link mechanism with the tip pin pivot portion as the vertex a and the attachment member locking points b and c as the base, and are held in place by a pair of springs 8 and 8. In this case, the displacement L of the guide rail 11 is dealt with by a change in the distance between the attachment member locking points bc.

The guide arm 20 having one end fixed to the side surface of the cage 13 has a link mechanism formed by inserting a spring 23 urged outward to form a diamond-shaped panda graph. A guide roller 21 that can be displaced in the horizontal direction at least to L / 2 and that is guided at the tip thereof along the guide rail 11 is provided.

The guide rail 11 and the cage 13 guided by the guide rail allow the relative displacement in the horizontal direction as described above, and correspond to the operation of the seismic isolation mechanism of the building. , The relative position with respect to the building, in particular, the relational position with the doorway changes as it is.

Returning to FIG. 1, when the cage 13 is displaced to a position A shown by a chain line in the figure, the frame 30 and the inner frame 39 are displaced.
a follows the arrow X direction by the connecting member 32,
The right angle direction is handled by the pandagraph mechanism of the connecting arm 33. Therefore, the inner door 15 of the cage 13
The opposing position of the outer door 31 does not change. Also, the connection between the elevator hall of the building and the frame 30 is:
Since the inner frame 30a moves along the outer frame 38 and the floor plate 36 slides on the lower surface of the floor 37 and follows the frame 30, the elevator can be moved in and out without any trouble.

[0017]

The present invention is constructed as described above. Since the frame supporting the external door follows the relative displacement of the guide rail, the relative position of the entrance and exit of the cage and the building. Is retained, so that there is no hindrance in and out. Therefore, it is possible to provide an elevator capable of operating the guide rail in a safe and reliable manner in correspondence with the intermediate seismic isolation building, by allowing the guide rail to have a certain degree of freedom and allowing the guide rail to be gently elastically deformed.
