Elevator landing door arrangement

Abstract

An elevator landing door arrangement for installation in a landing door opening of an elevator shaft wall includes at least one door jamb and at least one protective element fixed at the door jamb which abuts with its sealing portion against the landing door opening. The protective element has a fixing portion facing the door jamb, whereby either the fixing portion is bent around a carrier element of the door jamb or the carrier element extends around the fixing portion of the protective element.

Claims

1. An elevator landing door arrangement for installation in a landing door opening of an elevator shaft wall, comprising: at least one door jamb having a backside surface with an opening, wherein the backside surface comprises two backside parts facing one another with said opening located between said two backside parts, wherein the backside surface faces an elevator shaft; and at least one protective element fixed at the at least one door jamb, wherein the at least one protective element comprises a fixing portion connected to the at least one door jamb and a sealing portion which butts against a side surface of the elevator shaft wall, wherein the fixing portion passes around an outer surface of a first backside part of said two backside parts, through said opening into an interior space of said at least one door jamb and around an inner surface of the first backside part, and wherein the fixing portion is connected to the at least one door jamb via a fastener that extends through the fixing portion and the first backside part.

2. The arrangement according to claim 1, wherein the fixing portion is passed around the first backside part by 180 degrees.

3. The arrangement according to claim 2, wherein the at least one door jamb has a rectangular profile.

4. The arrangement according to claim 1, wherein the at least one door jamb has a rectangular profile.

5. The arrangement according to claim 1, wherein the at least one door jamb is made of metal.

6. The arrangement according to claim 1, wherein the at least one protective element is a metal sheet plate.

7. The arrangement according to claim 1 wherein the fixing portion and the first backside part form a labyrinth seal.

8. The arrangement according to claim 1, wherein the fixing portion of the at least one protective element is located at a first end of the protective element, and wherein the sealing portion is located at a second end of the protective element, the second end being opposite to the first end.

9. An elevator comprising the elevator door landing arrangement according to claim 1 in at least one landing opening of an elevator shaft wall.

10. The elevator according to claim 9, wherein the elevator shaft wall is made of concrete.

Description

(1) The invention is now schematically explained by means of an embodiment, whereby

(2) FIG. 1 shows a horizontal cross-section through the connecting area between a vertical door jamb part and the adjacent concrete elevator shaft wall.

(3) FIG. 1 shows an elevator landing door arrangement 10 located in a landing door opening 12 which is provided in a concrete elevator shaft wall 14 of an elevator. The arrangement comprises a door jamb 16 embodied as a rectangular door jamb profile with a front part 18, a first side part 20 facing the landing area, a second side part 22 facing the landing opening 12 and a first backside part 24 having a free edge 26 and a second backside part 27 which two backside parts 24, 27 together form the backside of the door jamb profile 16 facing the elevator shaft. The first backside part 24 of the door jamb profile 16 forms a carrier element for supporting a protective element 30 closing the gap 40 between the door jamb profile 16 and the concrete shaft wall 14. Accordingly, connected to the carrier element 24 and passing around its free edge 26 is a fixing portion 28 of the—preferably plate-like—protective element 30 which butts with its sealing portion 32 against the shaft side surface 34 of the elevator shaft wall 14. The fixing portion 28 of the protective element 30 has a bending 36 which surrounds the free edge 26 of the carrier element 24 of the door jamb profile 16. Via this arrangement, the fixing portion 28 of the protective element 30 butts tight against the carrier element 24 of the door jamb profile at two surfaces in a kind of labyrinth seal, so that no smoke or fire can pass this connection.

(4) The connection between the door jamb profile 16 and the protective element 30 is secured by fixing elements 38, particularly bolts, particularly screw bolts, which pass through the two layers of the fixing portion 28 of the protective element 30 adjacent to the bending 36, and through the carrier element 24 located in between. The fixing elements 38 therefore press these three layers together so that this connection is tight against passing smoke or fire. Via this means, the protective element 30 is in a sealed manner and rigidly connected to the door jamb profile 16 so that the gap 40 between the door jamb 16 and the elevator shaft wall 14 (whose width is exaggerated in the FIGURE for clarity reasons) is effectively closed.

(5) It shall be clear for the skilled person that the invention is not restricted to the shown embodiment but may be varied within the scope of the appended patent claims.
