Abstract

An illustrative example embodiment of an elevator door assembly includes a door panel having at least one edge. A base is configured to be received adjacent the edge of the door panel. An astragal is configured to be at least partially received over the base such that the base holds the astragal in a selected position aligned with the edge of the door panel. The astragal is at least partially compressible for closing off an interface between the edge of the door panel and an adjacent surface.

First claim

We claim:

1. An elevator door assembly, comprising:
a door panel having at least one edge;
a base configured to be received adjacent the at least one edge of the door panel, wherein the base includes a central body portion and a plurality of ledges extending from opposite sides of the central body portion; and
an astragal configured to be at least partially received over the base such that the base holds the astragal in a selected position aligned with the at least one edge of the door panel, wherein the astragal includes a central body portion and opposite ends that are spaced apart from each other by a gap within which the central body portion of the base is positioned, and the astragal being at least partially compressible for closing off an interface between the at least one edge of the door panel and an adjacent surface.

2. The assembly of claim 1 , comprising a second door panel and wherein the adjacent surface is on an edge of the second door panel.

3. The assembly of claim 1 , comprising a plurality of clips that secure the base to the door panel.

4. The assembly of claim 3 , wherein the plurality of clips are at least partially resilient for selectively engaging the door panel.

5. The assembly of claim 4 , wherein:
the at least one edge of the door panel includes a plurality of openings; and
at least some of the plurality of clips are at least partially received through some openings of the plurality of openings, respectively, for securing the base adjacent the at least one edge of the door panel.

6. The assembly of claim 5 , wherein
the plurality of clips each include a first portion that is configured to be inserted into one of the openings and at least one finger that is configured to hold the base adjacent the at least one edge of the door panel when the first portion is received in the one of the openings.

7. The assembly of claim 1 , wherein:
the central body portion includes a rear surface configured to be received against the at least one edge of the door panel and the plurality of ledges have opposing sides and extend in opposite directions from the central body portion in a direction that is parallel to the rear surface; and
the opposite ends of the astragal comprise curved portions that are positioned relative to the central body portion to establish a plurality of C-shaped channels where each C-shaped channel extends around the opposing sides of one ledge of the plurality of ledges to hold the astragal in the selected position.

8. The assembly of claim 7 , wherein the base comprises a metal extrusion.

9. The assembly of claim 8 , wherein the base comprises aluminum.

10. The assembly of claim 7 , wherein the astragal comprises an extrusion of a compressible material.

11. The assembly of claim 10 , wherein the compressible material is an elastomer.

12. The assembly of claim 11 , wherein the elastomer comprises rubber.

13. The assembly of claim 1 , the astragal comprises an extrusion of a compressible material.

14. The assembly of claim 13 , wherein the astragal is snap-fit over the base.

15. The assembly of claim 1 , wherein the door panel comprises a first elevator door panel and the at least one edge comprises a first edge for the first elevator door panel, and including a second elevator door panel with a second edge that faces the first edge, and wherein the base is attached to the first edge and the astragal is compressible against the second edge.

16. An elevator door assembly, comprising:
a first elevator door panel having a first edge;
a second elevator door panel having a second edge facing the first edge;
a base attached to the first edge; and
an astragal at least partially received over the base such that the base holds the astragal in a selected position aligned with the second edge, wherein the astragal comprises a central body portion with curved opposing ends extending from opposite sides of the central body portion, and wherein the curved opposing ends are spaced apart from each other by a gap, and the astragal being at least partially compressible against the second edge for closing off an interface between the first edge and the second edge.

17. The assembly of claim 16 , wherein the base includes at least one first opening and the first edge includes at least one second opening aligned with the at least one first opening, and including a clip that is inserted through aligned first and second openings to secure the base to the first elevator door panel.

18. The assembly of claim 17 , wherein the clip comprises a resilient first portion that is inserted through the aligned first and second openings and at least one finger that is positioned between a central portion of the base and the astragal, and wherein the central portion of the base is positioned within the gap between the curved opposing ends of the astragal.

19. The assembly of claim 18 , wherein the central portion of the base has a rear surface configured to be received against the first edge, and wherein the base further comprises a pair of ledges extending from opposite sides of the central portion, wherein the pair of ledges is offset from the central body portion, and wherein the pair of ledges have opposing sides that extend in a direction that is parallel to the rear surface.

20. The assembly of claim 19 , wherein the curved opposing ends form a pair of C-shaped channels that receive the pair of ledges such that each C-shaped channel extends around the opposing sides of one ledge of the pair of ledges.
