Description
[0001] The invention relates to a door sealing device for a completely watertight seal of a door mounted in a watertight frame, with a housing to be attached to a door having a bore through which a rotatably mounted bolt is guided, which is to be rotated by means of an activator for activating / deactivating a door locking system for opening and closing the door.
[0002] Door sealing devices of the type mentioned above are not known in the prior art.
[0003] However, there is an interest in providing a device for a watertight door in order to also make the door lock and / or the locking device that ensures watertight mounting of the door in a door frame watertight.
[0004] The object of the invention is therefore to create a device with which it can be ensured that, in particular, the lock and / or a locking device of an otherwise watertight door remains functionally sealed.
[0005] For a door sealing device of the type mentioned above, this problem is solved according to the invention by providing the bolt with a cylindrical sealing body for the purpose of a watertight seal of the bore, the outer surface of which interacts with the inner surface of a sealing ring mounted watertight within the housing, wherein the distance between the outer surface of the sealing body and the inner surface of the sealing ring is dimensioned in order to effect a watertight seal when the bolt and thus the sealing body rotate at least with low friction.
[0006] Preferred embodiments of the invention are the subject of the dependent claims, the elements of which serve to further improve the solution approach to the problem underlying the invention.
[0007] In the device according to the invention, the combination of features in which the bolt is provided with a cylindrical sealing body, the outer surface of which interacts with the inner surface of a sealing ring mounted watertight within the housing, wherein the distance between the outer surface of the sealing body and the inner surface of the sealing ring is dimensioned to ensure a watertight seal during at least low-friction rotation of the bolt and thus of the sealing body, makes it possible to design the bore of an otherwise watertight door to be functionally watertight.
[0008] According to a first preferred embodiment of the device according to the invention, the activator for activating / deactivating a door locking system for opening and closing the door is formed by a gearbox that can be operated by means of a lever.
[0009] The gearbox is preferably designed to drive a locking bolt rigidly connected to the door, which, in its extended position, engages in recesses formed in a door frame to press the door against sealing strips made of an elastic material and attached to the door frame. In its retracted position, the locking bolt releases the recesses formed in the door frame.
[0010] To ensure a robust, waterproof lock, the locking bolt is preferably arranged vertically.
[0011] According to another preferred embodiment of the device according to the invention, the activator for activating / deactivating a door locking system for opening and closing the door is formed by a hand lever that interacts with a conventional lock.
[0012] The housing, as in the first embodiment, is preferably designed for mounting on an outer surface of a door.
[0013] Typically, the bolt is formed by a polygonal bolt, in particular a square bolt.
[0014] The sealing body is preferably firmly connected to the bolt in a central area.
[0015] Furthermore, bolts and sealing bodies are preferably made of a metal and are particularly designed as a single piece.
[0016] According to an important preferred embodiment of the device according to the invention, the inner surface of the sealing ring is formed of a metal and the outer areas of the sealing ring furthest from the inner surface are made of an elastic plastic material.
[0017] Preferably, the sealing ring is mounted in a watertight manner in an inner recess of the sealing body, wherein at least on one side in front of the sealing ring a spacer ring is preferably arranged, which is also mounted in an adapted inner recess of the sealing body.
[0018] A retaining ring can preferably be arranged in front of the spacer ring, which is also mounted in an adapted inner recess of the sealing body.
[0019] The housing is preferably cylindrical in shape, with a flat outer surface and a flat inner surface, which can be attached in a watertight manner to a flat outer surface of a door.
[0020] Furthermore, the housing is preferably connected to an outer surface of an otherwise waterproof door by means of screws.
[0021] The distance between the outer surface of the sealing body (131) and the inner surface of the sealing ring (121) is preferably dimensioned to be between 5 and 50 micrometers, in particular 10 micrometers.
