DE19944447A1 - Seal and locking system for windows and doors uses hydraulically expanded seals pressing onto counterparts with or alternative to hydraulically powered locking fitments. - Google Patents

Abstract

The window and door sealing arrangements use hydraulics and inflatable seals for locking and sealing when pressed against correspondingly profiled counterparts plus an additional or alternative locking system of hydraulic powered fittings (4) or the two systems together. Control and power drive are obtained by leverage on handle or possibly remotely controlled electronics feeding to a drive unit via contact or switching loops.

Description

The seal causes stretchable hose-like elements attached to the frame or sash Sealing profiles that expand during the closing process and against one press a correspondingly shaped counter groove or a counter profile.

The inflation force can be increased mechanically by using leverage generated on the control handle, the force is applied hydraulically via a Media container with supply lines, as a medium can be air or a suitable liquid be used.

The power transmission to media containers that are also remotely located can be over Bowden cables happen.

This force can also be generated electronically via a pressure generator Switching process can be called up with control relays.

Opening processes via radio, infrared, motion detectors etc. are with this System can also be implemented.

With appropriately shaped profiling of the sealing hoses and the counter profile locking is achieved at the same time by the contact pressure.

The hydraulic system can also be used to move lock fittings of any kind to be used.

The elaborate window linkage in the sash is no longer required for windows, they are only small Supply cross-sections (cables, hose lines, Bowden cables) required.

Doors are climate and smoke-tight, highly sound-absorbing and quietly closing Systems feasible. When filling the sealing profiles with liquids that are exposed to heat solidify and seal, fire doors would also be possible.  

Explanation of the drawings (3 sheets)

Basic designs are shown in the drawings, a combination of the shown systems is possible. The alternative to installing the sealing profile and fittings in the Grand pianos to integrate this system in the frame or in the frame are not listed separately.
