2. Related Art
Fittings for swing leaf doors or sliding doors are generally connected to the door by clamping the door leaf or by of a bore in the door leaf. The functions of the multitude of fittings available on the market are considered as almost equal such that very often merely the design and the manufacturing quality are decisive factors. Failure of the fittings very often results in unexpected consequences for the user, in particular with glass doors which will break, and then the user might injured by the glass splinters. As fittings can be manufactured at very little technical expense, it is easy to counterfeit genuine products and to sell them at lower quality. It is then difficult for the manufacturer to distinguish the original from the counterfeit product.
Another problem with bonded fittings is the necessary safety for the user of the glass door. Failure of a bonded fitting leads in many cases to damaging or to breaking the glass door, whereby the user might incur serious injury. This risk is particularly high with shower doors made of glass. The manufacturer of the bonded fitting or of the door encounters the problem of having to determine the cause and to respond to warranty claims.
It is an object of one embodiment of the invention to provide a fitting, which allows for identification and in which all the manufacturing parameters can be stored.
One embodiment of the invention is characterized in that the fitting includes a transponder that allows for identifying the manufacturing parameters and the distribution chain. A consecutive serial number allows for exactly allocating the manufacturing parameters, place of manufacture and customer or wholesale merchant. The data can be retrieved via an Internet database such as to be able to verify at any time whether or not it is a genuine fitting and under which manufacturing parameters it was sold. Thereby warranty claims can be settled fast. The invention can be utilized in all types of fittings and in all doors, for example made of wood, metal, plastic material or glass.
In order to allow for quick and inexpensive storing of data during series production, a portion of the adapter is made from plastic material at or in which the transponder is disposed. As metallic structural components have a shielding or even insulating effect on data transmission, at least one structural component of the fitting should consist of plastic material such that the data can be stored already prior to mounting or completing the fitting.
The transponder is incorporated into the plastic material by a capsule, wherein the capsule protects the electronic components during the manufacturing operation. The transponder is embedded with the capsule into the plastic material during the manufacturing operation to allow for an inexpensive manufacturing.
The lower fitting part can be attached to the door leaf by clamping—like with a roller carriage of a sliding door—or by a bore. A compact and design-oriented solution consists in bonding the lower fitting part to the door leaf, whereby a low construction height is achieved for a roller carriage and a filigree disposition without a glass bore for a swing leaf door.
A preferred embodiment is achieved in that the lower fitting part is configured as an adhesive adapter, which consists of glass-fiber-reinforced polyamide. In particular for glass doors, the glass fibers protruding from the adhesive adapter achieve a glass-to-glass bonding, which results in a high quality and durable adhesive bond.
Another improvement is the result if the glass fiber portion is to the amounts of 50% to 70%, preferably of 60%. In this case, the plastic material serves as the support material for the glass-fibers. The above described glass-fiber portion provides the adapter with sufficient stability in order to carry a door via a hinge strap or via an adapter support.
In one embodiment a metallic adhesive adapter with a metallic bonding surface is provided with a coating of plastic material, in which the transponder is incorporated by a capsule.
A reproducible adhesive bond is achieved in that the adhesive adapter has a bonding surface and a counter-surface, wherein at least one web is disposed on the bonding surface, by which web the thickness of the adhesive layer is determined.
In this case, the webs may be configured as neps, stripes, or rings, which are very easily and inexpensively to manufacture.
A stable fitting, which is able to bear load, is realized in that an insert with a thread is incorporated into the adhesive adapter, wherein the thread is accessible from the counter-surface. The insert is directly embedded into the adhesive adapter during the injection-molding process and allows for a long life span without the thread experiencing any wear and tear.
Another improvement is achieved in that the thread of the insert is configured as a through-hole thread, the core removing hole continuing in the adhesive adapter. When screwing the fastener in, they cut a thread into the core removing hole, whereby an inexpensive and integral self-locking system is created.
Another measure enhancing the stability is achieved in that the insert has an undercut, which effects anchoring in the plastic material of the adhesive adapter.
As the counter-surface is chamfered towards the border of the adhesive adapter, a demoulding diagonal is created at the same time for the manufacturing process of the adhesive adapter during injection-molding of plastic material.
Fastening the adhesive adapter to the door leaf is realized by a UV-hardening and light-hardening acrylate adhesive. This adhesive is permanently resistant to aging.
To compensate for tolerances, a device for a vertical and/or horizontal and/or axial adjustability are disposed between the adhesive adapter and the hinge strap or the adapter support.
Hereinafter, further measures enhancing the invention will be illustrated in detail in conjunction with the description of one preferred embodiment of the invention based on the Figures, in which:

The thread 26 may be configured as a through-hole thread. The core removing bore 28 of the thread 26 continues in the adhesive adapter 20. When screwing the fastening elements 6 and 13 in for the first time, the thread of the fastening elements 6 and 13 passes through the thread 26 of the insert and, with the first thread turns, cuts a thread into the core removing hole 28. An inexpensive and integral self-locking is thereby created for the fastening elements 6 and 13.
The adhesive adapter 20 may consist of plastic material which is reinforced by glass-fibers. Usually the mating of the materials glass and plastic allows only for inadequate bonding. A glass-fiber-reinforced polyamide is used as the plastic material, which consists of 50 to 70%, preferably of 60% of glass fibers. During the injection-molding of the plastic material into the tool and during subsequent hardening, glass fiber ends protrude in a random arrangement from the adhesive adapter 20. This results in the effect that in principle glass is bonded to glass, which is a perfect mating of materials for this connecting method. In this case, the plastic material serves as the support material. The diagonal of the counter-surface 23, disposed towards the border of the adhesive adapter 20, serves at the same time as demoulding diagonal for the injection-molding process by which the adhesive adapter 20 is manufactured. The capsule 30 with the transponder 31 is simultaneously inserted into the adhesive adapter 20 during the manufacturing process.
Bonding between the bonding surface 21 and the glass surface is realized by a colorless UV-hardening and light-hardening acrylate adhesive, which as a solvent-free one component adhesive has the required resistance to aging. In this case, the bonding exclusively takes place on the door leaf without utilizing a front edge of the door.
In order to prove reproducibility of the adhesive layer, in addition to the thickness of the adhesive layer, other manufacturing parameters, such as humidity, temperature of the glass, setting time and setting temperature need to be documented. This documentation is stored in the transponder 31, which is incorporated in a capsule 30 into the adhesive adapter 20. During the manufacturing process of the adhesive bond, this data is computer-controlled and stored in the transponder. In this case, each adhesive fitting receives a continuous manufacturing number, which can be retrieved via an internet data base, among others with indication of the place of manufacturing and the customer. It is thereby possible to ensure at any time, that the present fitting, at which the bonding spot might have failed, is a genuine product to ensure warranty claims. The transponder 31 thus serves at the same time as a hidden copy protection, because especially glass fittings are easy to produce as copies or as a counterfeit products. Active or passive transponders based on RFID-technology can be utilized as the transponders 31. On account of the low performance of the RFID-technology, incorporating a transponder 31 into a metal fitting has its limitations. An adhesive adapter exclusively made of metal would have such a high insulation effect, that it would be very expensive to read the transponder 31. Therefore, a combination of an adhesive adapter 20, in which the transponder 31 is incorporated into the plastic material, is optimal, because incorporating the transponder 31 by capsule 30 during the injection-molding process is very easily and inexpensively realized, and automatic storing of the required parameters is possible during the manufacturing process.
