2. Description of the Related Art An escalator as a man conveyor, for example, has a truss and a balustrade installed between a lower floor and an upper floor of a building, and the truss incorporates a series of steps in which a number of steps are connected endlessly. An endless handrail belt is attached to the outer periphery of the balustrade, and the step train is driven endlessly by a driving device to convey passengers, and the handrail belt is driven endlessly in synchronization with the step train.

[0003] Each step of the step train is provided with a front wheel and a rear wheel on both sides thereof, and a guide rail for a front wheel for guiding the front wheel and a guide rail for a rear wheel for guiding the rear wheel are provided inside the truss. Each step travels along these guide rails, and each step is sequentially reversed at the end of the truss to change the direction of travel.

FIG. 5 shows a support structure of a guide rail at an end of a truss. A plurality of bracket members 2 are mounted inside a side beam 1a of the truss 1 so as to project toward the center thereof. An attachment plate 3 is detachably attached to the ends of the bracket members 2 via bolts 4 and nuts 5.

A plurality of support members 6a, 6b are fixed to one side surface of the mounting plate 3 by welding or the like, and a guide rail 7 for a front wheel and a guide rail 8 for a rear wheel are mounted on the support members 6a, 6b. The front wheel 12 and the rear wheel 13 provided on the side of the step 11 in the step row 10 are supported via the guide rail 7 for the front wheel and the guide rail 8 for the rear wheel.

[0006] Bracket member 2 attached to truss 1
And the mounting plate 3 supporting the guide rails 7 and 8 can be divided by removing the bolts 4 and the nuts 5, which allows the attachment and detachment of an endless handrail belt provided on the outer periphery of the balustrade. In order to

[0007]

However, in such a conventional configuration, a large number of bracket members 2 must be attached to the truss 1, so that the number of parts increases.
The structure becomes complicated, the assembling work is troublesome, and the management such as dimensional adjustment is troublesome. Then, the guide rails 7, 8 are supported by the cantilever structure with respect to the truss 1, which is disadvantageous in strength.

In addition, when attaching and detaching the handrail belt,
Remove the bolts 4 and nuts 5 one by one and
The bracket member 2 on the side and the mounting plate 3 on the guide rails 7 and 8 must be divided, so that the work of attaching and detaching the handrail belt is troublesome and the efficiency is reduced, and the bracket member 2 and the mounting plate 3 are further reduced. However, since a large number of bracket members 2 protruding from the truss 1 remain even when the above-mentioned structure is divided, these bracket members 2 hinder the work of attaching and detaching the handrail belt.

The present invention has been made in view of such a point, and an object of the present invention is to enable a guide rail to be firmly and stably supported by a simple structure without using a bracket member, and to be able to use a handrail belt. It is an object of the present invention to provide a guide rail support device for a man-conveyor which can easily and efficiently perform the work of attaching and detaching.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, there is provided a guide rail which guides the running of a step train near a reversing part where a step in a train of steps is installed inside a truss. In the guide rail support device of the conveyer for providing and supporting, a mounting plate is erected between the guide member for step reversal provided in the reversing portion and the truss cross beam provided in the vicinity of the reversing portion. The guide rail is supported via a mounting plate.

In particular, according to the second aspect of the present invention, a support member is provided on each of one side surface and the other side surface of the mounting plate, and the front wheel guides the front wheel of the step through the support member provided on one side surface. And a guide rail for a rear wheel for guiding the rear wheel of the step via a support member provided on the other side surface.

According to the third aspect of the present invention, a support member is provided at the upper end of the mounting plate on one side of the mounting plate, and a support member is provided on the other side of the mounting plate. A guide rail for a front wheel that guides the front wheel of the step through a support member provided at the upper end portion, and a rear wheel that guides the rear wheel of the step through a support member provided on the other side of the mounting plate. It is characterized by supporting the guide rail.
