Abstract

An exemplary door frame assembly that is useful in an elevator system includes a plurality of door frame members including a header, a sill and a plurality of jambs. The door frame members are configured to be secured into a desired position along a hoistway. At least one guide rail bracket is supported by at least one of the door frame members. The guide rail bracket is moveable relative to the door frame member between a handling position in which the guide rail bracket is generally parallel to at least one of the header or the sill and a deployed position in which the guide rail bracket is generally perpendicular to the at least one of the header or sill.

First claim

We claim:

1. A door frame assembly useful in an elevator system, comprising:
a plurality of door frame members including a header, a sill and jambs, the door frame members being configured to be located in a desired position along a hoistway; and
at least one guide rail bracket supported by at least one of the door frame members, the guide rail bracket being moveable relative to the at least one of the door frame members between a handling position in which at least a base of the guide rail bracket is generally parallel with at least one of the header or the sill and a deployed position in which at least the base of the guide rail bracket is generally perpendicular to the at least one of the header or the sill, the at least one guide rail bracket being situated for facilitating installing a guide rail in the elevator system in the deployed position.

2. The assembly of claim 1 , wherein the guide rail bracket base has a length that is longer than any other portion of the guide rail bracket.

3. The assembly of claim 1 , wherein the guide rail bracket is pivotally moveable relative to the at least one of the door frame members.

4. The assembly of claim 1 , comprising
a hinge securing the guide rail bracket to the at least one of the door frame members.

5. The assembly of claim 1 , wherein the at least one of the door frame members is spaced a distance from a wall of the hoistway that is perpendicular to the at least one of the header or the sill and the guide rail bracket is supported in a position such that a portion of the guide rail bracket is received against the wall in the deployed position.

6. The assembly of claim 1 , wherein the at least one of the door frame members is spaced a distance from a wall of the hoistway that is perpendicular to the at least one of the header or the sill and the guide rail bracket is supported in a position such that the guide rail bracket is spaced away from the wall in the deployed position.

7. The assembly of claim 1 , wherein the guide rail bracket comprises:
a car guide rail support arm near a first end of the base, the car guide rail support arm being adapted to secure a corresponding portion of a car guide rail in a desired position within a hoistway; and
a plurality of counterweight guide rail support arms between the car guide rail support arm and a second, opposite end of the base, the counterweight guide rail support arms each being adapted to secure a corresponding portion of a counterweight guide rail in a desired position within a hoistway.

8. The assembly of claim 7 , wherein the base, the car guide rail support arm and the counterweight guide rail support arms are all part of a single, integrated structure.

9. The assembly of claim 7 , wherein the base has one end section at the second end bent relative to a remainder of the base and one of the counterweight guide rail support arms comprises the bent end section.

10. The assembly of claim 7 , wherein the car guide rail support arm comprises three sections of the base near the first end that are bent to be transverse to each other.

11. The assembly of claim 10 , wherein a first one of the sections extends in a direction away from the base, a second one of the sections extends from the first one of the sections in a direction parallel to the base and a third one of the sections extends from the second one of the sections in a direction toward the base.

12. The assembly of claim 7 , wherein the car guide rail support arm has a rail receiving surface in a first orientation relative to the base and the counterweight guide rail support arms each has a rail receiving surface in a second, different orientation relative to the base.

13. The assembly of claim 12 , wherein the car guide rail support arm rail receiving surface is parallel to the base surface and the counterweight guide rail support arms rail receiving surfaces are generally perpendicular to the base surface.

14. The assembly of claim 7 , wherein
the base comprises a single metal plate:
the car guide rail support arm comprises a bent portion of the metal plate near the first end;
one of the counterweight guide rail support arms comprises a bent portion of the metal plate near the second end; and
another one of the counterweight guide rail support arms comprises another piece of metal secured to the base plate at a selected distance from the one of the counterweight guide rail support arms.
