Abstract

An elevator end termination includes a base member including a proximal end and a distal end and defining an internal belt cavity opening at the proximal end of the base member, an elevator belt comprising an outer jacket and an internal load carrier of a substantially rectangular cross-section, wherein the internal load carrier is exposed on an end of the elevator belt, in which a portion of the elevator belt end is positioned in the belt cavity, and an adhesive provided in the belt cavity at least between opposite sides of the elevator belt and opposing interior walls of the base member, in which the elevator belt is adhesively bonded to the base member.

First claim

The invention claimed is:

1. An elevator end termination, comprising:
a base member comprising a proximal end and a distal end and defining an internal belt cavity and an opening at the proximal end of the base member opening to the belt cavity, the belt cavity comprising opposing interior walls;
an elevator belt comprising an outer jacket and an internal load carrier, wherein a portion of the internal load carrier is exposed on an end of the elevator belt, wherein the exposed portion of the internal load carrier is positioned in the belt cavity;
a plate operatively connected to the base member to form the internal belt cavity, the base member and the plate pressed together to hold the exposed portion of the internal load carrier therebetween; and
an adhesive provided in the belt cavity at least between opposite sides of the internal load carrier and the opposing interior walls of the belt cavity,
wherein the elevator belt is adhesively bonded to the base member.

2. The elevator end termination of claim 1 , wherein, the internal load carrier is exposed on the portion of the elevator belt end that is adhesively bonded to the base member.

3. The elevator end termination of claim 1 , wherein the base member and the plate are connected to one another using a fastener extending through the base member and the plate.

4. The elevator end termination of claim 1 , wherein the adhesive comprises one or more of an epoxy, urethane, cyanoacrylates, or other single or multi-part structural adhesive.

5. The elevator end termination of claim 1 , wherein the internal load carrier of the elevator belt is of a substantially rectangular cross section, and
wherein the internal belt cavity is rectangular.

6. An elevator system, comprising:
at least one elevator car hoisted and lowered by an elevator belt, the elevator belt comprising an outer jacket and an internal load carrier, wherein a portion of the internal load carrier is exposed on an end of the elevator belt;
at least one end termination operatively connected to the elevator belt and the elevator car, the end termination comprising:
a base member comprising a proximal end and a distal end and defining an internal belt cavity and an opening at the proximal end of the base member opening to the belt cavity, the belt cavity comprising opposing interior walls, wherein the exposed portion of the internal load carrier is positioned in the belt cavity;
a plate operatively connected to the base member to form the internal belt cavity, the base member and the plate pressed together to hold the exposed portion of the internal load carrier therebetween; and
an adhesive provided in the belt cavity at least between opposite sides of the internal load carrier and the opposing interior walls of the belt cavity,
wherein the elevator belt is adhesively bonded to the base member.

7. The elevator system of claim 6 , wherein, the internal load carrier is exposed on the portion of the elevator belt adhesively bonded to the base member.

8. The elevator system of claim 6 , wherein the base member and the plate are connected to one another using a fastener extending through the base member and the plate.

9. The elevator system of claim 6 , wherein the adhesive comprises one or more of an epoxy, urethane, cyanoacrylates, or other single or multi-part structural adhesives.

10. The elevator system of claim 6 , wherein the internal load carrier of the elevator belt is of a substantially rectangular cross section, and
wherein the internal belt cavity is rectangular.
