Abstract

Example embodiments relate to an apparatus including a stationary first part, a movable second part, and a link arm mechanism connecting the first part and the second part. The first and the second link arm may be interconnected with a fifth articulated joint. First ends of the link arms may be connected with articulated joints movably on the first part. Second ends of the link arms may be connected with articulated joints on the second part. The second part may be moved with a first actuator in a first direction, with a second actuator in a third direction and with a third actuator in a fourth angular direction around the fourth articulated joint.

First claim

The invention claimed is:

1. An apparatus for alignment of an elevator guide rail, comprising:
a stationary first part having a first end and an opposite second end in a first longitudinal direction;
a movable second part having a first end and an opposite second end in a second longitudinal direction; and
a link arm mechanism connecting the stationary first part and the movable second part, said link arm mechanism including a first link arm having a first end and an opposite second end and a second link arm having a first end and an opposite second end, wherein:
the first end of the first link arm is attached with a first articulated joint to a first support element being movable and retainable by a first actuator in the first longitudinal direction along the first part of the apparatus and the second end of the first link arm is attached with a fourth articulated joint to a third support element being movable and retainable by a second actuator in the second longitudinal direction along the movable second part of the apparatus,
the first end of the second link arm is attached with a second articulated joint to a second support element being movable in the first longitudinal direction along the first part of the apparatus and the second end of the second link arm is attached with a third articulated joint to a third support element, the first end of the movable second part being movably supported on the third support element, a third actuator moving and retaining the movable second part in relation to the third support element,
the first link arm and the second link arm are connected to each other with a fifth articulated joint at a point where the first link arm and the second link arm intersect,
the first actuator is configured to move the second part in the first direction,
the second actuator is configured to move the movable second part in a third direction, in which the third direction is perpendicular to the first longitudinal direction, and
the third actuator is configured to move the movable second part in an angular direction around the fourth articulated joint.

2. The apparatus according to claim 1 , wherein the stationary first part is attached to a support bracket supporting the elevator guide rail on a wall structure of an elevator shaft and that the guide rail is attached to a front side of the movable second part.

3. The apparatus according to claim 2 , wherein the stationary first part of the apparatus comprises a first clamping device and a second clamping device for attaching the stationary first part to anchor bolts of the support bracket.

4. The apparatus according to claim 2 , wherein the movable second part of the apparatus comprises a third clamping device and a fourth clamping device for attaching the guide rail to the front side of the movable second part.

5. The apparatus according to claim 1 , wherein a first guide rod extending in the first longitudinal direction is attached to the stationary first part, wherein the first support element and the second support element are attached to the first guide rod so that the first support element and the second support element are configured to glide along the first guide rod.

6. The apparatus according to claim 1 , wherein a second guide rod extending in the second longitudinal direction is attached to the movable second part, wherein the third support element is attached to the second guide rod so that the third support element is configured to glide along the second guide rod.

7. The apparatus according to claim 1 , wherein the first actuator is formed of a screw extending in the first longitudinal direction through a first threaded hole in the first support element, and wherein one end of the first adjustment screw is attached to the first support element so that the first support element is configured to move in the first longitudinal direction when the first adjustment screw is turned in the first threaded hole.

8. The apparatus according to claim 1 , wherein the second actuator is formed of a second adjustment screw extending in the second longitudinal direction through a second threaded hole in the second support element, and wherein one end of the second adjustment screw is attached to the third support element so that the third support element is configured to move in the second longitudinal direction when the second adjustment screw is turned in the second threaded hole.

9. The apparatus according to claim 1 , wherein the third actuator is formed of a third adjustment screw extending in a third direction through a hole into a cavity in the third support element, the cavity receiving a protrusion that is attached to the first end of the movable second part, wherein an inner end of the third adjustment screw is configured to pass into the third threaded hole so that the movable second part is configured to move in an angular direction around the fourth articulated joint when the third adjustment screw is turned in the third threaded hole.

10. The apparatus according to claim 1 , wherein the stationary first part comprises an upper section and a lower section, the upper section further includes a stationary first sub-section and a movable second sub-section gliding on guide bars in the first longitudinal direction between an inner position and an outer position,
wherein a distance in the first longitudinal direction between the first clamping device located in the first sub-section and a second clamping device located in the second sub-section is adjustable.

11. A method for aligning an elevator guide rail, the method comprising:
fastening the stationary first part of the apparatus according to claim 1 to anchoring bolts of a support bracket of the guide rail,
fastening the guide rail to the movable second part of the apparatus,
adjusting the guide rail into a desired position with the apparatus,
fastening the guide rail to the support bracket,
unfastening the guide rail from the movable second part of the apparatus,
unfastening the first part of the apparatus from the anchoring bolts of the support bracket, and
removing the apparatus.
