Abstract

In a passenger conveyor balustrade apparatus, a lighting box includes: a ceiling portion; and a pair of side surface portions that protrude downward from the ceiling portion so as to face each other, an opening being disposed on a lower portion of the lighting box. A lighting holder that holds a lighting appliance is mounted inside the lighting box. The lighting holder has an elastically deforming portion. The lighting holder is held inside the lighting box by being pressed against the pair of side surface portions by elastically deforming the elastically deforming portion.

First claim

The invention claimed is:

1. A passenger conveyor balustrade apparatus comprising:
a lighting box that comprises:
a ceiling portion;
a pair of side surface portions that protrude downward from the ceiling portion so as to face each other; and
a pair of edge portions corresponding to the pair of side surface portions, both of the edge portions contacting and protruding from the corresponding side surface portion at a discrete angle,

an opening being disposed on a lower portion of the lighting box;
a lighting holder that is mounted inside the lighting box; and
a lighting appliance that is held by the lighting holder,
wherein:
the lighting holder has an elastically deforming portion, the lighting holder being held inside the lighting box by being pressed against the pair of side surface portions by elastically deforming the elastically deforming portion;
a vertical dimension of the lighting holder is less than a distance from the ceiling portion to the edge portions; and
a position of the lighting holder that is held inside the lighting box is adjustable vertically at least due to the vertical dimension of the lighting holder being less than the distance from the ceiling portion to the edge portions.

2. The passenger conveyor balustrade apparatus according to claim 1 , wherein:
the lighting holder has a pair of plate spring portions that are disposed on two sides of the lighting appliance as the elastically deforming portion; and
the pair of plate spring portions are respectively pressed against the corresponding side surface portions.

3. The passenger conveyor balustrade apparatus according to claim 1 , wherein a dimension of the lighting holder in a longitudinal direction of the lighting box is less than a width dimension of the lighting holder.

4. A passenger conveyor lighting holder comprising:
a mounting portion that is mounted inside a lighting box on which a ceiling portion and a pair of side surface portions that protrude downward from the ceiling portion and that face each other are disposed, the lighting box including a pair of edge portions corresponding to the pair of side surface portions, both of the edge portions contacting and protruding from the corresponding side surface portion at a discrete angle, an opening being disposed on a lower portion of the lighting box; and
a holding portion that is disposed on the mounting portion, the holding portion holding a lighting appliance,
the mounting portion having an elastically deforming portion, the mounting portion being held inside the lighting box by being pressed against the pair of side surface portions by elastically deforming the elastically deforming portion,
wherein:
a vertical dimension of the lighting holder is less than a distance from the ceiling portion to the edge portions; and
a vertical position of the lighting appliance is adjustable when held inside the lighting box at least due to the vertical dimension of the lighting holder being less than the distance from the ceiling portion to the edge portions.

5. The passenger conveyor lighting holder according to claim 4 , wherein the mounting portion has a pair of plate spring portions that are disposed on two sides of the holding portion as the elastically deforming portion.

6. The passenger conveyor balustrade apparatus according to claim 2 , wherein a dimension of the lighting holder in a longitudinal direction of the lighting box is less than a width dimension of the lighting holder.

7. The passenger conveyor balustrade apparatus according to claim 1 , wherein:
the angle at which the edge portions protrude from the corresponding side surface portion is 90 degrees.

8. The passenger conveyor balustrade apparatus according to claim 1 , wherein:
the lighting holder includes two vertical portions which contact the side surface portions, a horizontal portion, and two angled portions, each connected to a corresponding one of the vertical portions and the horizontal portion.

9. The passenger conveyor lighting holder according to claim 4 , wherein:
the angle at which the edge portions protrude from the corresponding side surface portion is 90 degrees.

10. The passenger conveyor lighting holder according to claim 4 , further comprising:
two vertical portions to contact the side surface portions, a horizontal portion, and two angled portions each connected to a corresponding one of the vertical portions and the horizontal portion.
