Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in handrail devices for curved escalators.

Conventionally, a curved escalator has been known which includes a conveyance path curved in a horizontal projection plane, a handrail erected along the longitudinal direction of this conveyance path, and a movable handrail arranged along the outer peripheral edge of the handrail. ing. The moving handrail of such a curved escalator is used as a guide similar to that of a normal straight elevator.
The path in which the moving handrail is curved in the vertical and horizontal planes is
Because it moves in a tilted position relative to the guide, it comes into strong local contact with the guide, increasing wear and tear.
There is a disadvantage that the movement resistance is large (requires a large driving force, and therefore the cost is high in terms of both production and maintenance).
Furthermore, when the moving handrail is tilted with respect to the guide, a large gap is formed in a part, and a part of a person's hand or finger on the conveyance path may get stuck in this part and be injured.

This invention aims to solve the above-mentioned drawbacks, and it is possible to support the lower part of one side wall of the longitudinal groove of the moving handrail and the upper part of the other side wall with guide rollers of different heights provided on the handrail. It is an object of the present invention to provide a handrail device for a curved escalator that has a simple structure, can maintain a movable handrail in a correct posture with respect to guide rollers, can be easily driven, is safe, and has less wear and tear.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

In FIGS. 1 and 2, 1 is the main frame of the curved escalator, 2 is a conveyance path provided in the main frame 1 and curved in the horizontal projection plane,
Reference numeral 3 designates handrails erected on both sides of the conveyance path 2 along the longitudinal direction thereof, and 6 designates a movable handrail. In Figures 3 to 6, 3a is a handrail deck forming the outer peripheral edge of the handrail 3, and 3b and 3c are convexities continuously formed on the outer peripheral edge of the handrail deck 3a along the longitudinal direction thereof. Reference numeral 4 denotes a group of guide rollers, and in this roller group 4, a large number of downward guide rollers 4a are respectively pivotally supported on the tips of shafts 4b that are tilted upright on the handrail deck 3a. Reference numeral 5 designates a group of guide rollers on the other side, and in this roller group 4, a large number of upwardly directed rollers 5a are each pivotally supported on a shaft 5b that is slanted upright on the handrail deck 3a. The movable handrail support portion 4a1 on the outer periphery of the downward roller 4a has a low height (,
The movable handrail support portion 5a+ on the outer periphery of the upward roller 5a is arranged at an incline so that the height is high, and the downward roller 4a,
The upward rollers 5a are connected to the movable handrail 60, the entrance E,
A downward roller 4a and an upward roller 5a are provided in a portion other than the folded curved portion A (see FIGS. 1 and 2).
and are alternately arranged in a staggered manner in the longitudinal direction of the moving handrail 6. The movable handrail 6 is made of rubber and is disposed endlessly over the entire length of the handrail deck 3a and within the main frame 1, and is configured to be driven in circulation by a drive device (not shown). Moreover, the moving handrail 6 has an opening 6a that opens toward the inner circumference.
The cross section with the longitudinal groove 6b, which is wider at the outer circumferential side than the longitudinal groove 6b, is formed into a substantially C-shape, and the one side and the other side guide roller groups 4 and 5 are fitted into the longitudinal groove 6b. And-
The gap and position between the side guide roller group 4 and the other side guide roller group are such that the movable handrail support parts 4a+ and 5a1 on the outer periphery of the guide rollers 4a and 5a are located slightly at the corner of the lower part of one wall and the upper part of the other side wall of the vertical passage 6b, respectively. It is set so that they come into contact with a pressing force of . Furthermore, the sides of the protrusions 3b and 3c provided on the handrail deck 3a and the opening 6a of the movable handrail 6a
The structure is such that there is a slight gap between each side wall.

In the handrail device according to the embodiment of the present invention configured as described above, the movable handrail 6 is arranged along the longitudinal direction of the handrail deck 3a constituting the outer peripheral edge of the handrail 3.
At this time, perform the following bending and stretching movements. That is, the movable handrail 6 is curved with the opening 6a inward at the folded curved portion A shown in FIGS. B, C, D
It curves in the left-right direction in FIG. The movable handrail 6, which bends and stretches in this way, generally tries to rotate in the direction of arrow a in FIG. 1 placed at intervals
ill and the other side roller groups 4 and 5 move the handrail 6
It is guided through the side wall of the vertical groove 6b. Movable handrail support portion 4 ax + on the outer periphery of each guide roller 4a, 5a
5. al guides the lower corner of one side wall and the upper corner of the other side wall of these vertical grooves 6b so as to prevent the rotation of the moving handrail 6, so that the moving handrail 6 can be moved as shown in FIG. A correct posture with respect to the handrail deck 3a is maintained, and deviation from the handrail deck 3a is prevented.

Therefore, combined with the rolling of each guide roller 4a, 5a, the movement resistance of the moving handrail 6 is reduced, and it can be driven with a small driving power.

In addition, there is less wear and tear due to movement of the moving handrail 6 (and maintenance costs can be reduced).Furthermore, the posture of the moving handrail 6 with respect to the handrail deck 3a is maintained correctly, and these protrusions 3b, 3c and the opening 6a Since the gap with the side wall can be minimized and made uniform, there is no fear that part of a person's hand or finger on the conveyance path 1 will enter the gap and be injured.

In this embodiment, since the movable handrail 6 does not curve in the folded curved portion A and the entrance/exit portion E on a horizontal plane, -
Each of the guide rollers of the side and other side guide roller groups 4 and 5 is provided with axes perpendicular to the handrail deck 3a, and is pivoted horizontally on these axes. What is necessary is just to structure it so that it may contact with pressing force.

Further, in the above-described embodiment, the shafts 4b and 5b are inclined so that the outer circumferential portions of the guide rollers 4a and 5a are brought into contact with the corner portions of the side walls of the longitudinal grooves 6b of the slider/slide 6.
As shown, a vertical axis 4b.

5b, horizontal guide rollers 4a, 5a are pivotally supported at different heights.
The lower part of one side wall and the upper part of the other side wall of b may be supported respectively. A device constructed in this manner can provide the same effects as those shown in FIGS. 1 to 6, and can also reduce the cost of each component.

As explained above, the present invention includes a conveyance path curved in a horizontal projection plane, a balustrade erected along the longitudinal direction of the conveyance path, and a movable handrail partially arranged along the outer periphery of the balustrade. In the curved escalator, the lower part of one side wall and the upper part of the other side wall of the vertical groove of the handrail are supported by guide rollers of different heights, which are pivotally supported by a number of shafts projected above the handrail. However, the curved portion of the moving handrail in the horizontal projection plane is guided by the guide roller. Therefore, according to this invention, the movable handrail that moves by bending the outer peripheral edge of the parapet will not rotate and tilt (the movable handrail can maintain its posture correctly with respect to the outer peripheral edge of the parapet, and therefore is safe). In addition, the movement resistance can be reduced, the handrail can be driven with a small driving force, reducing operating costs, and there is less wear and tear due to movement (therefore, it is possible to realize a handrail device that can be maintained at low cost).
