Abstract

The present invention relates to a fitting assembly with a housing for windows, doors and the like. The illustrated mounting assembly is characterized in that it includes a reservoir having a volatile corrosion inhibitor.

Description

Assembly unit

The invention relates to a mounting assembly for windows, doors and the like, in particular for door locks or window drives. The mounting assembly includes a housing.

In most embodiments and alternatives thereof, the fitting assembly is generally known, wherein it is generally made of metal. In such a fitted component, corrosion of the fitting may be exacerbated by environmental influences. These environmental effects may occur, for example, when the assembly is applied in a cheese house or the like.

In addition, when the fitting assembly is installed on a window or door made of a wooden material containing tannic acid or a wooden material treated with acetic acid, a problem of corrosion also occurs. Where the surface coating of a window or door is damaged when milling a recess, such as for a lock housing or window transmission, it may be the most severe place to corrode. Thus, tannic acid or acetic acid can reach the fitting through the damaged surface coating.

In these cases, it is conventional practice to use stainless steel materials for the fitting to prevent corrosion of the fitting components. However, the use of stainless steel materials increases the difficulty of manufacturing the assembly components and increases the production costs.

It is therefore the primary object of the present invention to provide a fitting assembly comprising a corrosion protection which is simple to implement, durable and low-cost.

The above object is achieved by a mounting assembly according to claim 1, in particular by a mounting assembly comprising a storage device with a volatile corrosion inhibitor.

On or in the mounting assembly, storage means can also be provided, namely: the corrosion inhibitor in the storage device is in liquid form or, preferably, in solid form. The corrosion inhibitor can flow out of the storage device and can in particular assume a gaseous state for the purpose of flowing out. In the gaseous state, the corrosion inhibitor may be distributed within or over the mounting assembly and form a corrosion inhibiting layer on the surface of the mounting assembly.

When the corrosion-promoting material reaches the vicinity of the metal surface of the mounting assembly, the corrosion-promoting material is "intercepted" by the corrosion inhibitor. That is, the corrosion inhibitor may, for example, react with corrosion-promoting materials. The resulting consumption of corrosion inhibitor can be compensated for by additional corrosion inhibitor overflowing from the storage device.

Thus, the provision of a reservoir with a volatile corrosion inhibitor enables the mounting assembly to be made of a metal that will typically corrode. By this method, it is possible to dispense with the use of an expensive stainless steel material. The storage device thus enables a simple corrosion protection which can be kept effective for many years on the basis of an overflow of the corrosion inhibitor from the storage device.

The German term "Fl ü chtige korrosones-Verhinder" may also be described as the English term "Vollate Corporation Inhibitors (VCIs)", meaning: volatile corrosion inhibitors (vapor phase corrosion inhibitors).

Preferred embodiments of the invention result from the description, the drawings and the dependent claims.

According to a first advantageous embodiment, the storage device at least partially surrounds the housing. The storage device may be surrounded to hinder gas exchange with the surroundings. After this, less corrosive material can reach, for example, the housing of the mounting assembly, thereby reducing the tendency of the mounting assembly to corrode. In addition, in such an arrangement, the reservoir prevents the volatile corrosion inhibitor from diffusing out of the mounting assembly or housing. In this way, a long-lasting protective function of the corrosion inhibitor is ensured.

Preferably, the storage means is made of a film and/or a plastic material. The volatile corrosion inhibitor can thus be stored in the film and/or the plastic material and escape therefrom in the form of a gas. For example, the membrane may surround the lock housing of the door lock, whereby a very high concentration of gaseous corrosion inhibitor may be achieved in the lock housing. Thus, the corrosion inhibitor reliably protects the lock housing and adjacent components of the mounting assembly from corrosion. Alternatively or additionally, the storage device further comprises paper, foam, slots, cavities and the like.

It is further preferred that the storage means is perforable for attaching the fixing to the mounting assembly. In particular, the film (described above) wound around the lock housing can be perforable, for example by means of screws, to fix the lock housing to the door leaf. The perforability has the advantage that the holes produced in the storage device in this way are closed off again directly (for example by means of a perforated screw), as a result of which the escape of gaseous corrosion inhibitors from the lock housing or housing in large quantities can be prevented. Furthermore, the open mounted components can be protected from soiling by the storage device.

According to a preferred embodiment, the storage device forms a cover of the housing. The storage device can be in particular a plastic cover which rests flat against the housing. For example, the storage device may be made of hard plastic or slightly flexible plastic. The cover may be pushed over the housing when the assembly is installed. The assembled assembly may then be used with a storage device (i.e., with a closure).

Preferably, the storage device is a hollow cuboid open on one side. The cuboid can be sleeved on a lock shell or a window transmission device. This cuboid shape can be particularly advantageous, since conventional lock housings and window transmissions likewise have a substantially cuboid shape. Accordingly, the storage device, which is designed as a cuboid, can be matched to the size and/or shape of the housing, whereby the assembly with the storage device can be designed to be only slightly larger than the assembly without the storage device.

Alternatively, the mounting assembly can be designed such that the outer dimensions of the mounting assembly with the storage device are equal to the outer dimensions of a common (preferably corresponding to standard) mounting assembly. In this case, for example, the housing can be designed smaller than conventional housings, so that the housing with the storage device has the dimensions of a housing of a standard assembly. The door lock with the storage device can therefore have the dimensions specified in standard DIN 18251 or DIN EN 12209, for example.

If the storage device is designed as a hollow cuboid with an opening on one side, then, in the installed state, for example, the lock housing of the door lock can be closed off on five sides by this cuboid and on the open side of the cuboid by a rib, so that a cavity is formed in this cuboid from which the volatile corrosion inhibitor can substantially not flow out. Thus, a high concentration of volatile corrosion inhibitor is achieved in the lock housing for a long time, which ensures a long-term protection.

Preferably, the storage means substantially hermetically closes the housing. That is to say that an air-tightness is achieved in the region of the storage device. As already described, a particularly high concentration of volatile corrosion inhibitors is thereby achieved in the housing. Furthermore, it is advantageous that the storage device has a dual function in this way. On the one hand, the storage device is used as a reservoir for the volatile corrosion inhibitor and, on the other hand, it is used as a seal for the housing.

In order to achieve gas tightness, the storage device has, in particular on its outside, an impermeable layer against corrosion inhibitors. In this way, the diffusion of the corrosion inhibitor out of the installation component or the metal surface of the installation component is prevented. Thus, the impermeable layer may retain the corrosion inhibitor within the assembled component.

According to a further advantageous embodiment, the storage means are also arranged within the housing. The storage device may also be divided into a plurality of sections. For example, one portion of the reservoir may be a folded film or sponge with a volatile corrosion inhibitor, wherein the film or sponge is disposed within the housing. By arranging it in the housing, it is possible to maintain a certain concentration of corrosion inhibitor there continuously, thereby protecting in particular the mechanisms there. In the installed state of the mounting assembly, evaporation can be further prevented by the closed installation of the mounting assembly.

Alternatively, the storage device may also be provided only within the housing. That is, the storage device does not extend out of the housing. In this case, the corrosion inhibitor may still diffuse out of the housing and protect the fitting from corrosion outside the housing. This protection of the assembly outside the housing can also be provided in other embodiments, in which the corrosion inhibitor flows out of the housing (for example for a door latch or a bolt) during operation, for example through small gaps. It is also possible in this way to protect the flange, the bolt and/or the bolt against corrosion.

Preferably, the volatile corrosion inhibitor comprises an amine, a nitride, an organonitrile, an organocarbonate, an organocarboxylate, an organochromate and/or an organophosphate. These materials can be present in the storage device, in particular in the form of salts, and evaporate continuously.

It is a further object of the present invention to provide a door or window having a fitting assembly of the above type. A storage device with a volatile corrosion inhibitor is foreseen in the door or window, wherein the storage device is arranged such that the corrosion inhibitor can protect the fitting components from corrosion.

According to one embodiment of the door or window, the storage means is arranged in a recess or recess. Being mounted in a recess or recess, the storage device is not visible from the outside, thereby giving the impression of being a "common" fitting assembly. Furthermore, this arrangement of the storage device prevents the volatile corrosion inhibitor from being released too rapidly into the ambient air, as a result of which a particularly long-lasting corrosion protection can be achieved.

Furthermore, the description relating to the fitting assembly according to the invention applies, in particular to its advantages and preferred embodiments, to doors or windows according to the invention.

It is a further object of the present invention to provide a method of installing a door lock in which a storage device having a volatile corrosion inhibitor is attached to the door lock and the door lock is installed on the door leaf together with the storage device. The storage device is also used continuously on the door lock (and thus in or on the door leaf) to ensure long-lasting protection against corrosion.

The invention also relates to a method of mounting a window transmission, in which method a storage device with a volatile corrosion inhibitor is mounted on the window transmission and the window transmission is mounted together with the storage device on the sash or frame.

The description relating to the fitting assembly according to the invention and the door (or window) according to the invention applies in particular to the advantageous effects and preferred embodiments thereof with respect to the method according to the invention.

The invention will now be described, by way of example only, with reference to the accompanying drawings.

Fig. 1 shows an exploded schematic view of a fitting assembly according to the invention.

Fig. 1 shows a fitting assembly 1 for a door. The assembly includes a door lock 10 having a housing designed as a lock housing 12 and a rib 14.

When the mounting assembly 1 is installed, a hollow plastic cuboid 16, which is open on one side, is pushed over the lock housing 12, wherein the door lock 10 and the plastic cuboid 16 together form the mounting assembly 1. The plastic cuboid 16 has an open side 18 and is used as a storage means for a volatile corrosion inhibitor (not shown). The corrosion inhibitor is stored in the plastic material of the plastic cuboid 16.

After the plastic cuboid 16 has been pushed onto the lock housing 12, the lock housing 12 and the plastic cuboid 16 are inserted into a milled recess 20 of a door leaf 22, and the collar 14 is screwed onto this door leaf 22.

After installation, the corrosion inhibitor is continuously emitted from the plastic material of the plastic cuboid 16, whereby a high concentration of the corrosion inhibitor is achieved in the recess 20. This prevents rusting of the door lock 10 and, in particular, of the components in the lock housing 12.
