Abstract

An adjustable handrail system for a top region of an elevator car includes a first stationary post fixed to a top surface of the elevator car and extending upwardly therefrom along a first longitudinal axis. Also included is a second stationary post fixed to the top surface of the elevator car and extending upwardly therefrom along a second longitudinal axis, the first and second stationary posts spaced from each other and oriented parallel to each other. Further included is an adjustable handrail panel translatable between a first position and a second position, the adjustable handrail panel operatively coupled to the first stationary post and the second stationary post and translatable perpendicularly relative to the first and second longitudinal axes and parallel to the top surface of the elevator car.

First claim

What is claimed is:

1 . An adjustable handrail system for a top region of an elevator car comprising:
a first stationary post fixed to a top surface of the elevator car and extending upwardly therefrom along a first longitudinal axis; a second stationary post fixed to the top surface of the elevator car and extending upwardly therefrom along a second longitudinal axis, the first and second stationary posts spaced from each other and oriented parallel to each other; and an adjustable handrail panel translatable between a first position and a second position, the adjustable handrail panel operatively coupled to the first stationary post and the second stationary post and translatable perpendicularly relative to the first and second longitudinal axes and parallel to the top surface of the elevator car.

2 . The adjustable handrail system of claim 1 , further comprising:
a first slide bracket fixed to the adjustable handrail panel proximate a first end of the first slide bracket, the first slide bracket defining a first slot; a first slide support pin extending through the first slot and slidably disposed therein, the first slide support pin secured to the first stationary post to operatively couple the adjustable handrail panel to the first stationary post; a second slide bracket fixed to the adjustable handrail panel proximate a first end of the second slide bracket, the second slide bracket defining a second slot; and a second slide support pin extending through the second slot and slidably disposed therein, the second slide support pin secured to the second stationary post to operatively couple the adjustable handrail panel to the second stationary post.

3 . The adjustable handrail system of claim 2 , wherein the first slide bracket and the second slide bracket are each operatively coupled to the adjustable handrail panel proximate a top edge of the adjustable handrail panel, the adjustable handrail system further comprising:
a third slide bracket fixed to the adjustable handrail panel proximate a first end of the third slide bracket and proximate a lower edge of the adjustable handrail panel, the third slide bracket defining a third slot; a third slide support pin extending through the third slot and slidably disposed therein, the third slide support pin secured to the first stationary post to operatively couple the adjustable handrail panel to the first stationary post; a fourth slide bracket fixed to the adjustable handrail panel proximate a first end of the fourth slide bracket and proximate a lower edge of the adjustable handrail panel, the fourth slide bracket defining a fourth slot; and a fourth slide support pin extending through the fourth slot and slidably disposed therein, the fourth slide support pin secured to the second stationary post to operatively couple the adjustable handrail panel to the second stationary post.

4 . The adjustable handrail system of claim 2 , further comprising a lock pin extendable through an aperture defined by one of the first stationary post and the second stationary post and through one of a plurality of slide bracket apertures defined by one of the first slide bracket and the second slide bracket, the lock pin fixing the adjustable handrail panel in the first position or the second position in an inserted condition.

5 . The adjustable handrail system of claim 1 , wherein the adjustable handrail panel is not rotatable.

6 . The adjustable handrail system of claim 1 , further comprising at least one intermediate position that the adjustable handrail may be translated to and fixed at, the at least one intermediate position located between the first position and the second position.

7 . The adjustable handrail system of claim 1 , wherein the elevator car has a front side, a rear side, a first side and a second side, the adjustable handrail system disposed on the top surface of the elevator car and proximate the first side, the adjustable handrail panel translatable toward and away from the second side.

8 . The adjustable handrail system of claim 1 , wherein the adjustable handrail system is translatable to access equipment mounted to a hoistway wall that the elevator car moves within.

9 . The adjustable handrail system of claim 8 , wherein the equipment mounted to the hoistway wall is an elevator system controller.

10 . The adjustable handrail system of claim 9 , wherein the first position of the adjustable handrail panel is a normal operating position and the second position is a controller servicing position.

11 . A method of adjusting a handrail panel on a top of an elevator car comprising:
unlocking the handrail panel; and translating the handrail panel between a first position and a second position, the handrail panel operatively coupled to a first stationary post and a second stationary post, the first and second stationary posts each fixed to a top surface of the elevator car and extending upwardly therefrom along respective longitudinal axes, wherein translating the handrail panel is made perpendicularly relative to the first and second longitudinal axes.

12 . The method of claim 11 , wherein translating the handrail panel comprises sliding the handrail panel relative to the first and second stationary posts with a first slide bracket operatively coupling the handrail panel to the first stationary post and a second slide bracket operatively coupling the handrail panel to the second stationary post, the slide brackets each defining a respective slot having a slide pin disposed therein and secured to the respective stationary post, the slide pin slidable within the slot.

13 . The method of claim 12 , wherein unlocking the handrail panel comprises removing a repeatedly insertable lock pin through one of a plurality of apertures of one of the first and second stationary posts and through one of a plurality of apertures of the slide bracket.

14 . The method of claim 11 , wherein the handrail panel is adjustable to access an elevator system controller mounted to a hoistway wall of a hoistway that the elevator car moves within.

15 . The method of claim 14 , wherein the first position of the handrail panel is a normal operating position to provide clearance between the handrail panel and other components within the hoistway and the second position is a controller servicing position.
