DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor device such as an escalator and a moving sidewalk, and more particularly, to a structure of a passenger conveyor device for increasing a degree of freedom of installation in a building.

[0002]

2. Description of the Related Art A passenger conveyor apparatus for carrying passengers by circulating and moving a plurality of steps endlessly to carry passengers is disclosed in, for example, Japanese Patent Application Laid-Open No. 5-213572. It is provided with a frame that is installed over the building beam on the side and the building beam on the lower floor, and at both ends of the frame, supporting beams that are arranged so as to overlap each other on both building beams are formed. . Conventionally, when the installation state is horizontally projected, it is usual to install the passenger conveyor device such that the longitudinal direction of the frame intersects at right angles to the parallel line of the two building beams.

[0003]

In the conventional passenger conveyor device, the longitudinal direction of the frame body intersects the upper building beam and the lower building beam, which are parallel to each other, at right angles. As described in the official gazette, even if the system has an adjustment function that can cope with a change in the dimension between building beams to some extent, if the full length of the passenger conveyor device cannot be stored within the right angle between the building beams, installation is basically impossible. It has been possible.

That is, in the conventional passenger conveyor device, the legal upper limit inclination angle is set from the lower floor to the upper floor.
It is necessary to secure a (30 degree) ramp and a horizontal path of a predetermined length connected to this ramp to accommodate the step drive system equipment. If the total length of the ramp and the horizontal road is greater than the right angle between the beams of the building on which the installation state is horizontally projected, the installation of the passenger conveyor device is impossible and the installation has to be abandoned. .

[0005] In particular, when removing an old passenger conveyor device that has passed 20 to 30 years after installation, and trying to install a new passenger conveyor device within the same building beam interval at the same installation location, the above-mentioned constraint conditions are imposed. Is a problem. To improve safety, for example, the horizontal traveling distance, which was conventionally one tread, is extended to three treads to increase the number of horizontal traveling steps at the entrances and exits. Design and Construction Guidance Guidelines ”(1995 edition:
In line with the guidance on securing maintenance work space issued by the Tokyo Metropolitan Elevator Safety Council, there was a problem that the length of the machine room was extended and passenger conveyor equipment etc. using the latest improved technology could not be installed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger conveyor device in which a frame having an effective length longer than this interval can be installed between building beams parallel to each other at a narrow interval, thereby increasing the degree of freedom of installation.

It is another object of the present invention to provide a passenger conveyor device having a more economical installation structure which improves the space competition between the passenger conveyor device and the building beams.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a frame which is installed at a distance from and parallel to a building beam on an upper floor and a building beam on a lower floor. Prepared,
In the passenger conveyor device, the supporting beams at both ends of the frame body are respectively fixed on the building beams by being overlapped and fixed, and a plurality of steps connected endlessly along the longitudinal direction of the frame body are circulated and transported to carry the passenger. The frame has an effective length longer than a right angle interval between the building beams on a horizontal projection plane, and is installed such that a longitudinal direction of the frame intersects obliquely with a parallel line between the building beams. Propose a passenger conveyor device.

The support beams at both ends of the frame are joined to the terminal end of the frame so as to obliquely intersect the longitudinal direction of the frame.

In the case where the left and right lengths of both ends are different so that the frame body becomes a parallelogram on the horizontal projection plane, the support beam is
It is attached diagonally to both ends of the parallelogram frame.

If the length of the left and right sides of both ends is the same so that the frame becomes a rectangle on the horizontal projection plane, the length of the left and right sides of the support beam is different, and both ends of the rectangular frame are Are mounted at right angles.

[0012] In any case, the upper support beam and the lower support beam may be covered with a getting on / off floor,
It may be covered on the building floor.

According to the present invention, by adopting such a structure, it is possible to install a new passenger conveyor between narrow building beams, and the competition of space between the floor for getting on and off and the floor of the building is also reduced. An improved and more economical passenger conveyor system can be realized.
