Abstract

The invention relates to a rope terminal assembly of an elevator fixing an elevator rope to a fixing base such as an elevator unit, said elevator being suitable for transporting passengers and/or goods, said assembly comprising an elevator rope, whose width is larger than its thickness in a rope transverse direction, with at least one end comprising a first member with a first end face and a second member with a second end face, a wedge element, a wedge housing, the rope terminal assembly comprising a rope gap through which said elevator rope passes and said wedge element is arranged to wedge between the first member with the first end face and the second member with the second end face of the elevator rope thus locking said elevator rope in the gap, and an elevator.

First claim

The invention claimed is:

1. A rope terminal assembly of an elevator, the elevator configured to transport passengers and/or goods, the rope terminal assembly comprising:
an elevator rope, the elevator rope including a width that is larger than a thickness of the elevator rope in a rope transverse direction, the elevator rope including a plurality of separate members, the plurality of separate members including a first member with a first end face and a second member with a second end face, at least a portion of the second member clamped to at least a portion of the first member;
a wedge element;
a wedge housing; and
a rope gap through which the elevator rope passes and the wedge element is configured to wedge between the first member and the second member to lock the elevator rope in the rope gap,
wherein the portion of the second member is clamped in direct contact with the portion of the first member separately from and externally to the wedge element and the wedge housing,
wherein the rope terminal assembly is configured to be fixed to an elevator unit.

2. The rope terminal assembly according to claim 1 , wherein the first member and the second member each include one or more non-metallic load-bearing parts of a plurality of non-metallic load-bearing parts, such that at least two non-metallic load-bearing parts of the plurality of non-metallic load-bearing parts are on opposite sides of the wedge element.

3. The rope terminal assembly according to claim 2 , wherein the plurality of non-metallic load-bearing parts include outermost load-bearing parts and innermost load-bearing parts, the outermost load-bearing parts and the innermost load-bearing parts on opposite sides of the wedge element.

4. The rope terminal assembly according to claim 2 , wherein the plurality of non-metallic load-bearing parts are coated with an elastomeric material coating, and the plurality of non-metallic load-bearing parts are separated from each other based on the elastomeric material coating being split into branches accommodating the wedge element.

5. The rope terminal assembly according to claim 1 , wherein the wedge element is an elongated element including a first contact surface portion arranged against the first member and a second contact surface portion arranged against the second member.

6. The rope terminal assembly according to claim 1 , wherein the wedge element includes a first contact surface and a second contact surface, the first contact surface and the second contact surface arranged against the elevator rope, the first contact surface and the second contact surface associated with an equal friction property.

7. The rope terminal assembly according to claim 1 , wherein the wedge housing is symmetrical with respect to a longitudinal axis of the wedge housing.

8. The rope terminal assembly according to claim 1 , further comprising:
a rope end block attached to at least one end of the elevator rope, the rope end block attached on a side of the first end face of the first member with respect to the wedge element.

9. The rope terminal assembly according to claim 8 , wherein the rope end block includes an electrically non-conductive material.

10. An elevator configured to transport passengers and/or goods, the elevator comprising:
a hoistway;
at least one elevator unit movable in the hoistway, the at least one elevator unit including an elevator car; and
a lifting device; and
the rope terminal assembly according to claim 1 , wherein the rope terminal assembly is fixed to the at least one elevator unit.
