Abstract

Provided is a guide shoe for a passenger conveyor, including: a base portion to be slid across a skirt guard provided along a moving direction of a plurality of steps that are movably provided; and a weight containing a material having a specific gravity larger than a specific gravity of a material of the base portion, which is provided to the base portion.

First claim

The invention claimed is:

1. A guide shoe for a passenger conveyor, comprising:
a base portion to be slid across a skirt guard disposed along a moving direction of a plurality of movable steps;
a weight at the base portion; and
a clearance between the weight and a connector of each of the plurality of movable steps, and
wherein the connector is to hold the base portion.

2. The guide shoe for a passenger conveyor according to claim 1 , wherein the base portion has a back surface on a side opposite to the sliding surface thereof, and the weight is on the back surface.

3. A passenger conveyor, comprising:
a plurality of the guide shoe for a passenger conveyor of claim 1 ;
the plurality of steps that are movable; and
a plurality of the skirt guard disposed along the moving direction of the plurality of steps,
wherein the plurality of the guide shoes are mounted to each of the steps.

4. A guide shoe for a passenger conveyor, comprising:
a base portion to be slid across a skirt guard disposed along a moving direction of a plurality of movable steps; and
a weight at the base portion,
wherein the weight is at such a position that a moment of inertia about a combined center of gravity of the base portion and the weight is larger than a moment of inertia about a center of gravity of the base portion in a plane that is orthogonal to a sliding surface of the skirt guard and a sliding surface of the base portion, on which the sliding occurs, and extends along a sliding direction in which the base portion is slid across the skirt guard.

5. The guide shoe for a passenger conveyor according to claim 4 , wherein the base portion has a back surface on a side opposite to the sliding surface thereof, and the weight is on the back surface.

6. A passenger conveyor, comprising:
a plurality of the guide shoe for a passenger conveyor of claim 4 ;
the plurality of steps that are movable; and
a plurality of the skirt guard disposed along the moving direction of the plurality of steps,
wherein the plurality of the guide shoes are mounted to each of the steps.

7. A guide shoe for a passenger conveyor, comprising:
a base portion to be slid across a skirt guard disposed along moving direction of a plurality of movable steps; and
a weight at the base portion,
wherein the weight is at such a position that a distance from a contact point between the skirt guard and the base portion to a combined center of gravity of the base portion and the weight is larger than a distance from the contact point between the skirt guard and the base portion to a center of gravity of the base portion.

8. The guide shoe for a passenger conveyor according to claim 7 , wherein the base portion has a back surface on a side opposite to the sliding surface thereof, and the weight is on the back surface.

9. A passenger conveyor, comprising:
a plurality of the guide shoe for a passenger conveyor of claim 7 ;
the plurality of steps that are movable; and
a plurality of the skirt guard disposed along the moving direction of the plurality of steps,
wherein the plurality of the guide shoes are mounted to each of the steps.

10. A guide shoe for a passenger conveyor, comprising:
a base portion to be slid across a skirt guard disposed along a moving direction of a plurality of movable steps; and
a weight at the base portion,
wherein the base portion has a sliding surface to be slid across the skirt guard and side surfaces orthogonal to the sliding surface, and the weight is on each of the side surfaces.

11. The guide shoe for a passenger conveyor according to claim 10 , wherein the base portion has a back surface on a side opposite to the sliding surface thereof, and the weight is on the back surface.

12. A passenger conveyor, comprising:
a plurality of the guide shoe for a passenger conveyor of claim 10 ;
the plurality of steps that are movable; and
a plurality of the skirt guard disposed along the moving direction of the plurality of steps,
wherein the plurality of the guide shoes are mounted to each of the steps.
