Description

The present invention relates to a fitting arrangement for windows, doors and the like, in particular a door lock or a window gear. The fitting arrangement comprises a housing.

Fitting assemblies are basically known in a variety of embodiments and variants, these are often made of metals. In such fitting arrangements, increased corrosion of the fitting parts may occur due to environmental influences. Such environmental influences can occur, for example, when using the fitting arrangements in cheese dairies and the like.

In addition, the problem of corrosion can occur when the fitting assemblies are attached to windows or doors made of woods which contain tannic acid or have been treated with acetic acid. Corrosion may then be greatest where a surface coating of the windows or doors is damaged by milling away pockets (e.g., for a lock case or window gear). Due to the damaged surface coating, the tannic or acetic acid can then reach the fittings.

Conventionally, corrosion of the fitting assembly in such cases is prevented by the use of a stainless steel material for the fitting parts. The use of stainless steel, however, complicates the manufacture of the fitting assembly and also increases their cost.

It is therefore the object underlying the invention to provide a fitting arrangement which comprises an easy to implement, durable and cost-effective corrosion protection.

This object is achieved by a fitting arrangement according to claim 1. The fitting assembly of claim 1 includes a reservoir with volatile corrosion inhibitors.

On or in the fitting arrangement, therefore, the reservoir can be arranged, in which the corrosion inhibitors are present in liquid or preferably solid form. The corrosion inhibitors can escape from the reservoir and, in particular, assume a gaseous state for emergence. In the gaseous state, the corrosion inhibitors may disperse in the fitting assembly and form a corrosion inhibiting layer on the surfaces of the fitting assembly.

If a corrosion-promoting substance now comes close to a metal surface of the fitting arrangement, the corrosion-promoting substance is "intercepted" by the corrosion inhibitors. This means that the corrosion inhibitors can react, for example, with the corrosion-promoting substance. The consumption of the corrosion preventer occurring in this way can be compensated for by subsequent flow of further corrosion inhibitors from the reservoir.

The provision of the reservoir with volatile corrosion inhibitors thus makes it possible to form the fitting assembly from metals that are fundamentally subject to corrosion. In this way can be dispensed with the use of expensive stainless steel material. The reservoir thus provides a simple way to realize a corrosion protection, which may remain effective for many years due to the post-flow of the corrosion preventer from the reservoir.

Volatile corrosion inhibitors are also referred to as Volatile Corrosion Inhibitors (VCIs).

Preferred embodiments of the invention are described in the description, the drawings and the subclaims.

According to the invention, the reservoir encloses the housing at least partially. The reservoir can obstruct gas exchange with the environment by enclosing. As a consequence, less corrosive substances, e.g. get to the housing of the fitting assembly, whereby the corrosion tendency of the fitting assembly is reduced. In addition, in such an embodiment, the reservoir prevents the volatile corrosion inhibitors from diffusing away from the fitting assembly. A long-lasting protective function of the corrosion preventer is ensured in this way.

Preferably, the reservoir is formed from a film and / or a plastic material. The volatile corrosion inhibitors may then be incorporated in the film and / or the plastic material and outgassed from the film and / or the plastic material. For example, a film can enclose the lock case of a door lock, whereby a very high concentration of gaseous corrosion inhibitors can be achieved within the lock case. The corrosion preventers reliably protect the lock case and adjacent parts of the fitting arrangement from corrosion. Alternatively or additionally, the reservoir may also comprise a paper, a foamed material, a tub, a cavity and the like.

More preferably, the reservoir is pierceable to attach fasteners to the fitting assembly. In particular, the (above-mentioned) wound around the lock case film may be pierceable to the lock case for Example with screws to fix in a door leaf. The pierceability has the advantage that in this way resulting holes in the reservoir directly (eg by means of piercing screws) are closed again, whereby leakage of the gaseous corrosion preventer from the lock case or the housing can be largely prevented. In addition, open positions of the fitting arrangement can be protected by the reservoir from contamination.

According to a preferred embodiment, the reservoir forms a cap for the housing. The reservoir may in particular be a plastic cap, which rests flat against the housing. For example, the reservoir may be formed of a stiff or less flexible plastic. The cap can be pushed onto the housing during assembly of the fitting arrangement. Subsequently, the fitting assembly may be installed together with the reservoir (i.e., the cap).

The reservoir is preferably a hollow cuboid open on one side. The cuboid can be put over the lock case or the window gear. The cuboid shape may therefore prove to be particularly advantageous because conventional lock boxes and window gear also have approximately a cuboid shape. The formed as a cuboid reservoir can therefore be adapted to the size and / or the shape of the housing, whereby a fitting arrangement with reservoir can be formed only slightly larger than a fitting arrangement without reservoir.

Alternatively, the fitting arrangement can be designed so that the outer dimensions of the fitting arrangement with reservoir are equal to the outer dimensions of a customary, preferably one of a standard, fitting arrangement. For this example, the housing can be formed so smaller than usual, so that the housing with reservoir the dimensions of a housing of a standardized Has fitting arrangement. A door lock with reservoir can then have the dimensions specified in the standard DIN 18 251 or DIN EN 12209, for example.

If the reservoir is formed as a hollow cuboid open on one side, a lock case of a door lock, for example, can be closed on the five sides by the parallelepiped and on the open side of the cuboid by the forend, resulting in a cavity inside the cuboid the volatile corrosion inhibitors can not escape substantially. In the lock case thus a long time high concentration of volatile corrosion inhibitor is achieved, which ensures long-term protection.

Preferably, the reservoir closes the housing substantially gas-tight. This means that gas-tightness is achieved in the area of the reservoir. As already described, a particularly high concentration of the volatile corrosion inhibitors is thus achieved in the housing. In addition, there is the advantage that the reservoir assumes a dual function in this way. First, the reservoir serves as storage for the volatile corrosion inhibitors. On the other hand, it serves as a sealant for the housing.

In order to achieve gas-tightness, the reservoir, in particular on an outer side, may have a layer which is impermeable to the corrosion preventer. In this way it is prevented that the corrosion inhibitors diffuse away from the fitting arrangement or its metal surfaces. The impermeable layer may thus hold the corrosion inhibitors within the fitting assembly.

According to a further advantageous embodiment, the reservoir is also arranged inside the housing. The reservoir can therefore be divided into several parts his. For example, a portion of the reservoir may be a pleated foil or a sponge with volatile corrosion inhibitors, with the foil or sponge disposed within the housing. Due to the arrangement in the interior of the housing, a certain concentration of corrosion inhibitors is constantly maintained there, which in particular protects the mechanics present there. In the installed state of the fitting arrangement, evaporation can be largely prevented by the completed installation of the fitting arrangement.

Alternatively, the reservoir can also be arranged only within the housing. This means that the reservoir does not extend to the outside of the housing. In this case, the corrosion inhibitors can also diffuse outside the housing and protect fittings outside the housing from corrosion. Such protection of fittings outside of the housing may also be provided in other embodiments if the corrosion inhibitors can exit the housing (e.g., the latch or the latch) through, for example, small gaps in passages. In this way, the faceplate, the latch and / or the lock bolt can also be protected from corrosion.

Preferably, the volatile corrosion inhibitors include amines, nitrides, organic nitrites, organic carbonates, organic carboxylates, organic chromates and / or organic phosphates. In the reservoir, these substances can be present in particular as salts and evaporate continuously.

Another object of the invention is a door or a window according to claim 9. The door or window comprises a fitting arrangement of the type described above. In the door or window, a reservoir with volatile corrosion inhibitors is provided, wherein the reservoir is arranged such that the volatile corrosion inhibitors can protect the fitting assembly from corrosion.

According to one embodiment of the door or the window, the reservoir is arranged in a groove or a pocket. Due to the arrangement in the groove or the pocket, the reservoir can not be visible from the outside, giving the impression of a "conventional" fitting arrangement. In addition, too rapid a release of the volatile corrosion preventer is prevented by the arrangement of the reservoir to the ambient air, whereby a particularly long-lasting corrosion protection can be achieved.

Incidentally, the statements regarding the inventive fitting arrangement apply to the door according to the invention or to the window according to the invention, in particular with regard to advantages and preferred embodiments.

Another object of the invention is a method according to claim 11. According to the method, the reservoir is thus permanently installed on the door lock and thus in or on the door leaf, to ensure a long-lasting corrosion protection.

For the inventive method apply to the fitting arrangement according to the invention and the door (or window) according to the invention Statements accordingly, in particular with regard to advantages and preferred embodiments.

a fitting assembly according to the invention in a schematic exploded view.

Fig. 1 shows a fitting assembly 1 for a door. The fitting arrangement comprises a door lock 10, which has a housing designed as a lock case 12 and a forend 14.

On the lock case 12 a one-sided open, hollow plastic cuboid 16 is pushed during assembly of the fitting assembly 1, wherein the door lock 10 and the plastic cuboid 16 together form the fitting assembly 1. The plastic cuboid 16 has an open side 18 and serves as a reservoir for volatile corrosion inhibitors (not shown). The corrosion inhibitors are incorporated in the plastic material of the plastic squarer 16.

After pushing the plastic squarer 16 on the lock case 12 of the lock case 12 and the plastic cuboid 16 is inserted into a milled pocket 20 of a door leaf 22 and the forend 14 screwed to the door leaf 22.

After installation, the corrosion inhibitors continuously flow out of the plastic material of the plastic squarer 16, whereby a high concentration of the corrosion inhibitors is achieved within the pocket 20. These thus prevent rusting of the door lock 10 and in particular of the components in the lock case 12.
