Description

The invention relates to a fitting system according to the unpowered Hauptanmeidung DE 101 19 897.3. The fitting system allows the rotatable mounting of a door leaf in a glass construction, wherein on the door leaf top and / or bottom side a fitting is arranged, which cooperates with a complementary counter fitting.

Such a fitting system is known from the patent application DE 199 59 530. For this purpose, preferably made of glass door leaves by means of fittings upper and / or lower side rotatably mounted in a surrounding frame structure. By using different counter fittings, the fitting system is suitable for both frame structures made of masonry as well as plate-shaped elements, such. Glass. The door leaves can be used for single or double-leaf pendulum or stop doors. The rotary fittings cooperate with those installed on the frame counter fittings, with complementary bearing elements rotatably mesh. The rotary fittings are subdivided in longitudinal extent by a gap to form opposing contact surfaces in at least partially spaced fitting parts, wherein the two fitting parts are fastened by transverse to the longitudinal extent screwed screws while reducing the gap on the door panel.

The problem with such rotary fittings on the one hand, the arrangement of the fittings and on the other hand, the arrangement of the screws. The fact that the load transfer exclusively on the mounted in the door leaf level Fittings, it can lead to unwanted tension in the door leaf.

After installation, the screws are still accessible to anyone and therefore not protected against manipulation or contamination. Furthermore, the freely visible screws represent an interruption of the fitting surface, so that a non-uniform overall visual impression is created.

It is therefore an object of the invention to develop a fitting system according to the preamble of claim 1 so that the fitting assembly is stabilized and the fittings are executed tamper-proof and protected, so that beyond a visually appealing unit. Furthermore, the assembly of the well-known from the Hauptanmeidung fitting should be simplified.

This object is achieved with the features specified in claim 1. Advantageous embodiments of the subject matter of claim 1 are given in the dependent claims.

The door fitting according to the invention according to claim 1 has the advantage that a tamper-evident arrangement of the fitting crossing pins within a form-fitting attachable rod approach a tamper-proof and visually appealing fitting is created. The surface of the fitting or the rod approach is formed without interruption and the other shape design adaptable, so that the fitting including the rod approach is an optical unit.

The fitting is divided by a running in the longitudinal direction gap in two fitting parts, which are integrally connected to each other via a web. Between these fitting parts, the door leaf is clamped clamped. The rod lug is fixed to one of the fitting parts, whereby the pins crossing the fitting parts are secured and covered in their position. The rod extension is arranged parallel to the door leaf level and can be extended outside of the fitting by means of a rod which is optionally connected to the door leaf. As a result, further attachment points are created so that tension within the door panel can be avoided.

The inventive arrangement and design of the two pins within the rod approach allows a simplified installation of the fitting. In a first assembly step, the fitting is fastened non-positively to the door leaf. Trained on the inside of the rod approach cross bores then crown the protruding pin heads of the crossing pins. In both pin heads radially encircling grooves are formed. The mechanical connection of the rod lug with the pins is finally done by the upper and lower side axially screwed into the rod lug screws, which engage by clamping in the grooves of the pin heads.

Since a threaded screw is screwed into the bottom part of the rod approach, with a ground-level mounting of the fitting or the door leaf due to the small distance from the horizontal environment no access thereto possible. The fitting is thus executed tamper-proof.

To ensure the setting of a defined clamping force during assembly of the fitting, both pins are applying clamping force Threaded into the fittings screwed. By trained in two pin heads groove a position indicator is created because only with sufficient depth of engagement, the positive positioning of the rod lug in the receiving channel and subsequently complete screwing the screws into the grooves is possible.

In order to allow a damage-free mounting of the pins, axially recessed Allen key are formed in the pin heads. As a result, on the one hand a defined approach of a tool is possible and at the same time prevents the pins are damaged. Conceivable, for example, tangentially opposite key surfaces or Außensechskante.

In one embodiment, the rod extension concealing the two pins can be extended to form a stabilizing handle bar, which optionally runs from an upper to a lower fitting of a door leaf. At the joints between the rod parts or at any location of the rod can be created by so-called point fittings that enforce the glass, connections to the door leaf.

The rod parts are inserted into one another, with the rod formed with radially stepped end regions having O-rings arranged in annular grooves, while the rod set has a bore area enlarged in cross-section. The O-rings are squeezed when nesting the rod parts and thereby form a sufficiently frictional connection. This type of connection allows easy assembly and disassembly.

In order to easily place the door leaf with the preassembled fittings between the journal protruding above and below the door opening in the bearing axis of the door, one of the two fittings has a laterally openable area. Advantageously, a storage space of a fitting is formed laterally openable for this purpose. In this case, a bearing body equipped with a socket is pre-mounted on the corresponding frame-side bearing, so that then the door leaf can be pivoted with the storage space on one side open receiving the bearing body in the bearing axis of the door leaf. The bearing body is then mounted in the storage room with opportunities for fine adjustment of the door leaf within the bearing axis. The storage space can be closed laterally by means of a cover which can be inserted flush with the surface, so that an optical unit is created. Preferably, clips arranged on the side of a lateral surface are used to fasten the cover.

The fitting, the rod approach and the rod or their items can be made of different metals, such. As brass, iron, stainless steel, aluminum or bronze, made of a suitable the necessary strength having plastic or from corresponding mixed materials. The fitting, the rod approach and the rod are advantageously manufactured in a casting process as one-piece parts and then finely processed. The flowing course of the outer contours reduces casting manufacturing problems.

The same or equivalent components are provided in the following description with the same reference numerals.

A fitting system usually consists of several fittings and Gegenbeschlägen, wherein in the following description two differently designed fittings are shown in detail, which must be used once on a door leaf use to ensure easy installation. Both fittings are each denoted by 1.

Basically, the fitting 1 is used for storage, preferably made of glass door leaves 2, the upper and / or underside rotatably mounted in a surrounding glass structure, wherein a bearing axis extends in the door leaf level. Different counter fittings (not shown) allow use for frame structures of plate-shaped materials or masonry. The door leaves 2 can be used for single or double-leaf pendulum or stop doors.

The fitting is made of metallic material and preferably has a round cross-section. It is divided by a extending in Längserstrekkung gap 3 into two fitting parts 4 and 5, which are integrally connected to each other via a web 6. Between inner contact surfaces 7 and 8 of these fitting parts 4 and 5, the door leaf 2 is clamped clamped (Figures 1 and 2).

The fitting 1 according to FIGS. 3 and 4 can be mounted on the underside of the door leaf 2 in a corresponding recess 9. In the web 6 of the fitting 1 there is a storage space 10 with an integrally formed rotary body 11, which can record, for example, the end of a closer shaft of a door closer, not shown, non-positively and positively. In a manual movement of the door leaf 2 of the door closer is tensioned, so that the door then closes automatically.

The fittings 4 and 5 are penetrated transversely by two holes formed parallel to each other, wherein the holes each composed of a blind bore 12, 13 in the fitting part 4 and a respective through hole 14, 15 in the fitting part 5. The blind holes 12 and 13 each have an internal thread. In the holes two differently long-trained pins 16, 17 are introduced, each having a pin head 18, 19, in each of which an axially recessed hexagon socket 20 is formed. Each pin 16, 17 has a radially circumferential groove 21, 22 and a threaded shaft 23. Between the door leaf 2 and the respective fitting part 4, 5, a support 25, 26 is used, which serves as a surface protection. The pads 25, 26 have corresponding openings which are aligned with the holes. Between the fitting parts 4, 5 also not shown spacers can be arranged in the form of washers, which limit the distance or the clamping force between the fitting parts 4, 5 in the screw connection to the door leaf 2.

A round rod lug 27 is fixed to the fitting part 5, wherein the fitting part 5 for this purpose is partially formed with a receiving channel 28 in which the rod lug 27 rests positively. The rod extension 27 can be extended by means of a rod 29, which serves as a handle or stabilizing rod and ends in an upper fitting 1. The rod attachment 27 according to FIG. 5 is penetrated centrally on the upper and lower sides by axial threaded bores 30, 31, the threaded bore 30 having a cross-sectional enlarged bore region 32. In the threaded holes 30, 31 each screw 33 can be screwed. Furthermore, the rod extension 27 has two transverse bores 34, 35, which terminate in the threaded bores 30, 31. These two transverse bores 34, 35 have the same distance as the corresponding holes in the fitting parts 4 and 5.

The rod part 29 according to FIG. 6 is formed at both ends with a radially stepped end region 36, wherein 37 O-rings 38 are arranged in annular grooves formed in this end region 36.

Since the fittings 1 are preassembled on the door leaf 2, one of the two fittings 1 has a laterally openable area in order to place the door leaf 2 with the preassembled fittings 1 between the bearing journals projecting above and below the door opening in the bearing axis of the door can.

According to the figures 7 to 10 for a fitting 1 is provided, the storage space 39 is laterally openable. In the storage space 39, a bearing body 40 can be fastened, wherein a screw connection, not shown, engages through an integrally formed on the bearing body 40 mounting boss 46. In order to allow an adjustment of the door leaf 2 within the bearing axis, the mounting lug 46 is formed with a slot 41. Within the bearing body 40 of the frame-side pivot pin is rotatably supported by a bush 42. The storage space 39 is laterally closed by means of a cover 43. A lateral surface 44 of the cover 43 is convex, so that the cover 43 flush with the surface of the rest of the fitting 1 inserts and an optical unit is formed. For attachment of the cover 43 of the lateral surface 44 clips 45 are arranged laterally.

The actual assembly of the fitting 1 takes place in such a way that the door leaf 2 between the contact surfaces 7, 8 and the supports 25, 26 of the fitting parts 4, 5 is clamped. The two pins 16, 17 are screwed into the corresponding bores 12 to 15 and clamped the door leaf 2. Subsequently, the rod extension 27 with the two transverse bores 34, 35 via the projecting into the receiving channel 28 pin heads 18, 19 are positively positioned. The mechanical connection of the rod extension 27 with the pins 16, 17 is finally made by upper and lower side axially in the threaded holes 30, 31 of the rod extension 27 screwed screws 33 which in the grooves 21, 22nd the pin heads 18, 19 engage frictionally. Since the rod extension 27 extends almost directly above the floor after assembly of the door leaf 2 and the screw 33 is screwed flush in the rod extension 27, a tamper resistant fitting 1 has been created , which also looks visually appealing.

The upper-side fitting 1 is mounted analogously to the above description, wherein the rod 29 is inserted before the final attachment of the corresponding rod extension 27 of the upper fitting 1. The rod 29 is inserted at both ends with the respective end portion 36 in the cross-sectional enlarged bore portion 32 of the respective rod attachment 27. The O-rings 38 are squeezed when nesting and thereby form a sufficiently frictional connection of all rod parts.

The final assembly of the door leaf 2 in the door opening between the stationary existing upper and lower bearings will be briefly described below. The underside fitting 1 is inserted with its rotating body 11 on the corresponding lower bearing journal and the door leaf 2 is pivoted in the plane of the bearing axis. Beforehand, the bearing body 40 with the inner bushing 42 is pushed onto the upper bearing journal of the door leaf 2. Subsequently, the door leaf 2 is pivoted with the storage space 39 on one side completely open by receiving the bearing body 40 in the bearing axis of the door leaf 2. The bearing body 40 is then finely adjusted and fixed in the storage space 39 by means of the attachment lug 46 and the slot 41. Finally, the storage space 39 and the bearing body 40 located therein is closed by means of the clippable cover 43.
