Embodiment Construction

[0062] exist Figure 2a A seal according to the invention is shown in , hereinafter referred to as a drop seal. Such drop seals are installed in the lower region of the leaf of a revolving or sliding door. For this purpose, the drop seal is either pushed into a lower groove of the door leaf, fastened to the lower end side, or arranged laterally in the lower region of the door leaf. Installation in the upper region or in the lateral region of the door leaf is likewise possible. If terms such as "lower" and "upper" are used below, these positional and directional statements relate to the use of a drop seal in the lower region of the door leaf. The term applies similarly to other installation positions and the description and claims shall also include the term.

[0063] When the door leaf is closed, the drop seal automatically and mechanically lowers in order to protect the gap between the door leaf and the building base against light, draft and sound. Depending on the constr...

Abstract

A sealing device for a door has a housing rail (1), a sealing strip, which is held in the housing rail (1), with a carrier rail (2) and with a sealing profile (3), and a drop-down mechanism (4, 6, 60)for raising and lowering the sealing strip (2, 3). The drop-down mechanism (4, 6, 60) is fastened to the housing rail (1) in a first fastening point (7) and to the carrier rail (2) in a second fastening point (8). The second fastening point (8) allows a displacement of the sealing strip in the longitudinal direction (L) of the sealing device and relative to the housing rail (1). This allows simple adaptation to door situations in situ, with it being possible in particular for the drop-down seal to be shortened to a desired length without the carrier rail then protruding too far.

Description

technical field [0001] The invention relates to a descending seal for a door, in particular to a mechanically descendable sealing device. Background technique [0002] Automatically mechanically lowerable seals are known. Said sealing device is generally used for doors without a threshold in order to seal the lower gap between the door leaf and the floor against drafts, noise and light. Seals such as those disclosed in EP 0 338 974 have proven themselves. [0003] When closing and opening the door, the actuation of the actuation seal is carried out automatically on one or both sides by pressing in a spring-loaded trigger bolt protruding from the door leaf when closing the door. Thus, the weather strip descends via the descending mechanism. When opening the door leaf, the trigger bolt is released again, and due to the restoring force of the spring, the lowering mechanism lifts the sealing strip again. [0004] Examples of corresponding lowering mechanisms are disclosed in...
