Abstract

A connecting element connects a first wall panel with a second wall panel. A first spring element is supported on the upper part of the connecting element and on one side of a first bend. A second spring element is supported on the upper part and on one side of a second bend. The other side of the second bend presses on one side of the first bend. The connecting element is introduced without a tool into a first slot of the first bend and the second bend is placed at a second slot over the connecting element.

First claim

We claim:

1. An elevator cage component, comprising:
a first elevator cage panel, the first elevator cage panel comprising a first slot;
a connecting element, the connecting element comprising an integral spring body having a first spring element and a second spring element, the connecting element being insertable into the first slot such that the first spring element presses on the first elevator cage panel, the connecting element further being insertable into the first slot by manual assembly; and
a second elevator cage panel, the second elevator cage panel comprising a second slot, the second slot being configured to receive the connecting element such that the second spring element presses on the second elevator cage panel wherein the first spring element extends through the second slot,
wherein the first elevator cage panel includes an end face having a first bend, the first slot being arranged at the first bend, the first slot having a first wide region and a first narrow region, and the second elevator cage panel includes an end face having a second bend, the second slot being arranged at the second bend, the second slot having a second wide region and a second narrow region, and the second bend having a reduced thickness near the second narrow region.

2. The elevator cage component of claim 1 , the first wide region and the second wide region each being wider than the connecting element, the connecting element comprising a narrow region, the first narrow region and the second narrow region each being configured to receive the narrow region of the connecting element.

3. The elevator cage component of claim 1 , the first spring element being wider than the first narrow region and the second spring element being narrower than the second narrow region.

4. The elevator cage component of claim 1 , the connecting element comprising an upper part for pushing the connecting element into the first slot.

5. An elevator cage component assembly method, comprising:
providing a connecting component comprising an integral spring body having a first spring element and a second spring element;
inserting the connecting component into a wide region of a first slot of a first elevator cage panel such that the first spring element of the connecting element presses on a first bend of the first elevator cage panel;
pushing a narrowed region of the connecting component in a first direction from the wide region of the first slot into a narrow region of the first slot;
inserting the connecting component into a wide region of a second slot at a second bend of a second elevator cage panel; and
displacing the connecting component in the first direction from the wide region of the second slot into a narrow region of the second slot such that the second spring element of the connecting element presses on the second bend of the second elevator cage panel wherein the first spring element extends through the second slot thereby coupling the first cage panel to the second cage panel.

6. An elevator installation comprising:
an elevator cage, the elevator cage comprising,
a first elevator cage panel, the first elevator cage panel comprising a first slot including a narrow region opening into a wide region,
a connecting element, the connecting element comprising an integral spring body having a first spring element and a second spring element, the connecting element being insertable into the wide region of the first slot and then slidably displaced into the narrow region of the first slot such that the first spring element presses on the first elevator cage panel, the connecting element further being insertable into the first slot by manual assembly, and
a second elevator cage panel, the second elevator cage panel comprising a second slot including a narrow region opening into a wide region, the second slot oppositely directed with respect to the first slot, the second slot being configured to receive the connecting element into the wide region of the second slot and then by sliding displacement into the narrow region of the second slot such that the second spring element presses on the second elevator cage panel and the first spring element extends through the second slot.
