Description

The invention relates to a fitting part for a window or a door according to the preamble of claim 1. In particular, the invention relates to a so-called center closure for a rotary wing window. In the following, the part to be opened and closed will be referred to as a wing and the part fixed to it as a frame.

The fitting has the task of creating a pressure of the wing to the frame. This may have the sense to compensate for the manufacturing tolerances of the wing or the frame occurring during the production or by time after assembly and to maintain a greater and better tightness by the pressure. Tolerances can also occur in that such large distances occur between different fitting parts of a composite fitting that the frame or the wing bends when closing the wing. Here are simple fitting parts to use the so-called center closures that divide these long distances and generate an additional pressure force at the subdivision points. It may also be desirable to increase by the fitting part exerted by another closure device of the entire fitting pressure force of the wing against the frame to ensure a particularly good tightness.

The fitting part can also have the task to form an additional inhibition against pressing or breaking the wing.

As already stated, the invention relates to a fitting part, which is used as a center fastener for swing casement or swing doors. In these applications, fittings are known which forward via espagnolette and corner baffles an actuating movement of an operating lever over more than one or all sides of the wing in order to effect at several the wing circumference distributed locations by closure devices, a locking and a pressing force of the wing against the frame. However, it is also conceivable to use the fitting according to the invention in turn-tilt wing windows or doors to easily adjust the pressure force of the wing against the frame.

A fitting part of this kind is by the DE 19853544 B4 already known. The known locking fitting consists of two locking parts, wherein a wedge is provided on a latch part, which cooperates to generate the pressing force with the other latch part when closing the wing. For this purpose, the second latch part engages behind the wedge on the first latch part and thereby interacts with a ramp surface of the wedge on the first latch part. In the second latch part a Andruckverstellung is permanently mounted.
By these measures, relatively high pressure forces for the pressure between the wing and the frame can be obtained from the closing movement of the wing out, ie generally from the wing closing force of a person closing the wing, but for this advantageous feature according to many Single components needed, which adversely affects the assembly and increases the assembly time. In a multi-component of individual components can consequently increase the proportion of mounting devices, which causes an increase in the cost of production and thus makes the component uneconomical.

Other fitting parts described variously in the prior art, in particular center fasteners have a relatively high component cost, but have the other hand, by the resilient or otherwise movably mounted fittings or parts of fittings a limited pressure.

The invention has for its object to provide a fitting for producing an adjustable pressure force between a wing and a frame, which is manufacturing technology simple and inexpensive and can be mounted in a simple, fast, safe and precise manner and adjusted, and which avoids the aforementioned disadvantages ,

To solve this problem, a fitting for a window or a door in a frame and a pivotally mounted thereto wings with a first latch member and a second latch member is provided, which has a first latch member with a first wedge of a second latch member when closing the Wing engages behind such that a pressure of the wing is effected on the frame and while the latch members are immovably mounted during the closing or opening movement in the pressing direction.
The first latch part consists of a mounting plate and an adjusting device for adjusting the pressure. In this case, the mounting plate is integrally connected to the first wedge and has a receptacle for the rotatable adjustment of the adjusting device having Exzenterspreizdübels. The first latch member engages preassembled by the Exzenterspreizdübel in a bore on the frame, wherein the Exzenterspreizdübel is penetrated by a central bore, which forms a guide and receiving a fastener.

By these measures, out of the closing movement of the wing, i. In general, from the wing closing force of a person closing the wing relatively high pressure forces for the pressure between the wing and the frame are obtained. In the variously described in the prior art fasteners with resilient or otherwise movably mounted fittings the maximum compressive forces are on the other hand limited or can be produced only by a variety of components.

In order to maintain this pressure force, when the wing or the frame have changed in shape over time, manufacturing tolerances occur or wear occurs on the latch parts, an adjusting device is provided with which the wedge can be adjusted in or against the direction of pressure , This adjusting device is advantageously designed so that they have a in the Pressure direction requires minimal space, so basically has no effect on the shape of the first latch part.
That the pressure force is not immediately built up immediately at the end of the closing movement of the wing, but spread over a certain angular range of the closing movement to the end of the closing movement and as a force increasing to the end of the closing movement is generated, with a relatively smooth and easy to use Mobility of the wing is ensured and at the same time relatively high pressure forces can be provided, results in an advantageous manner in that the first wedge of the first latch member arranged with the second latch member second wedge interacting ramps form an undercut, in one the pressure direction cutting plane has an approximate circular arc shape around the pivot axis of the wing of the window or the door.

The mounting plate is inventively provided to be able to arrange the adjustment laterally next to the wedge, so not in the direction of pressure in front of or behind the wedge. For this purpose, the receptacle of the adjusting device is designed as a circular bore, which is arranged at the respective ends of the mounting plate. A head part of the Exzenterspreizdübels passes through the recording playfully rotatably. In an advantageous embodiment of the head part snaps into the receptacle and is held by a positive connection or the head part is riveted non-positively, so that the Exzenterspreizdübel is still rotatably held in the receptacle. As a result, on the one hand, the width of the first Riegeteiles remain limited, on the other hand, a relatively wide configuration in the direction of pressure of the wedge is possible. Furthermore, the fitting part consisting of the mounting plate and arranged on each side of the wedge Exzenterspreizdübel is easier and faster to assemble as a one-piece component.

For ease of design and connection during assembly of the mounting plate with the Exzenterspreizdübel is provided that the mounting plate has a space between the inside of the frame and this side facing the mounting plate for receiving a merging from the head of the Federal Exzenterspreizdübels. Due to the collar having a stop, the eccentric expansion anchor can be precisely adjusted in its position. In addition, the gap of the mounting plate is partially to the adjustment and Fastening position flush filled with the mounting plate, so that with attachment to the frame a high tightening force of the fitting is achieved with simultaneous rotation inhibition and thus positional adjustment of the Exzenterspreizdübels.

For ease of design and connection during assembly of the fitting part to the two with a predetermined length spacing having holes of the frame is provided that the Exzenterspreizdübel has a shank, the part facing away from its head end free end over a portion of its length at least once slotted with a longitudinal slot is and has circumferentially a chamfer or a radius. Through the longitudinal slot of the shaft is spring force. In order to easily achieve a slight bias of the fitting in a pre-assembled position in the frame, the diameter of the shaft is slightly larger than the diameter of the bore in the frame. Due to the chamfer or the radius at the free end of the shank, the fitting part can be adjusted automatically and inserted into the bore of the frame.

Before the mounting screws permanently secure the fitting part to the frame, the mounting plate can be adjusted in a pre-assembly in a simple manner by turning the Exzenterspreizdübel within the bore of the mounting plate and the bore in the frame to pressure, the axes of rotation of the head part within the mounting plate and the shaft in the bore eccentric to each other. To Andruckverstellung, the Exzenterspreizdübel on a central bore, which is designed to receive a fastening screw and additionally has a Werkzeugingriffausnehmung. The Werkzeugingriffausnehmung extends over a central portion of the central bore and is formed as an internal hex recess. About a lever tool, the Exzenterspreizdübel are eccentrically rotatable in slightly biased mounting position, and thus cause a positional adjustment of the mounting plate in the pressing direction.
When the correct position has been reached, the final assembly of the fitting part can be carried out by completely screwing in the fastening screws.

An advantageous embodiment is achieved in that the fastening screws are screwed into the central bore of the Exzenterspreizdübels. To avoid Unevenness and to achieve a tight fit of the fitting, the Exzenterspreizdübel in the head part has a recess for the head part of the fastening screw. As a result, the fastening screw is designed flush with the mounting plate and the Exzenterspreizdübel.

Another advantage is the fact that the fastening screw requires no further receiving bore in the first latch part, which unnecessarily increases the first latch part in the length perpendicular to the pressing direction and thus in the embodiment unnecessarily, resulting in a complication and increase in the cost of the construction of the first latch part Episode has.

The Werkzeugingriffausnehmung forms a guide of the fastening screw and is dimensioned slightly larger in diameter than the nominal thread diameter of the fastening screw. This has the advantage that even with subsequent unscrewing of the fastening screw, the inner hexagonal recess is undamaged and a readjustment of the fitting part can be operated by a lever tool.

At high demands of burglar resistance, it may prove advantageous if the shaft tapers towards the free end, but is designed to be consistent in outer diameter.
Preferably, the taper is dimensioned smaller in diameter than the core diameter of the fastening screw, which spreads apart with engagement of the fastening screw in the shaft in the preassembled state of the first latch member on the frame of the shaft in the bore of the frame and so a non-positive connection of the first latch member with the Frame manufactures.

In order to meet the requirements of a high pressure force and increased in the closed position of the window or door security against burglary, the mounting plate is made of a metallic material or a combination of metal and plastic. The Exzenterspreizdübel should be made of an elastic material, for example made of a plastic, since the shaft of the Exzenterspreizdübels is spread in the bore of the frame by the fastening screw and jammed or pressed into the frame. But it is also conceivable to produce the Exzenterspreizdübel of a metallic material, as the spreading of the shaft is considered to be minor.
Barb-like projections can also be attached to the expansion dowel, which effect a higher positive connection between the first locking part and the frame.

For ease of design and connection during assembly of the fitting part, the fitting part may be symmetrical in the longitudinal direction and transverse to the fitting. Since the first latch part is formed symmetrically already transversely to the groove, it requires only a small design effort to achieve symmetry in the longitudinal direction of the fitting by the wedge of the first latch member is the same shape on both sides to match the arc shape.

In the FIG. 1 is a fitting 1 for a window or a door in a frame 2 and a pivotally mounted thereto wings 6 with a first latch part 3 and a second latch part 4 is provided, which the first latch part 3 with a first wedge 5, which is engaged behind by a second latch member 4 during the closing of the wing 6 such that a pressure of the wing 6 is effected on the frame 2 and thereby immovably mounted the latch members 3, 4 during the closing or opening movement in the pressing direction are.

The first latch part 3 after FIG. 2 and FIG. 3 consists of a mounting plate 7 and an adjusting device 8 for adjusting the Andrucks. In this case, the mounting plate 7 is integrally connected to the first wedge 5 and has a receptacle 9 for the rotatable mounting of the adjusting device 8 forming Exzenterspreizdübels 10 after FIG. 4 and FIG. 5 on. To FIG. 1 engages the first latch member 3 through the Exzenterspreizdübel 10 in a frame 2 having bore 11 and can be preassembled with it. The Exzenterspreizdübel 10 is after FIG. 2 penetrated by a central bore 12 and forms a guide and receiving a fastener 13th

By these measures, out of the closing movement of the wing 6 out, i. In general, from the wing 6 closing force of the wing 6 closing person out relatively high pressure forces for the pressure between the wing 6 and the frame 2 are obtained. The latch parts 3 and 4 are preferably mounted near the pivot axis 20.

In order to maintain the pressure force of the fitting part 1, when the wing 6 or the frame 2 have changed in shape over time, manufacturing tolerances occur or wear occurs on the latch parts 3.4, a readjustment by the adjusting device 8 is provided with the wedge 5 can be adjusted in or against the pressing direction. The adjusting device 8 is advantageously designed so that it requires a minimal space requirement in the pressing direction, ie in principle has no effect on the shape of the first latch part 3.

That the pressing force is not immediately built up immediately at the end of the closing movement of the blade 6, but distributed over a certain angular range of closing movement to the end of the closing movement and so a force increasing to the end of the closing movement is generated, with a relatively smooth and easy operable mobility of the wing 6 is ensured and At the same time relatively high pressure forces can be provided, resulting in an advantageous manner FIG. 1 in that the first wedge 5 of the first latch part 3 with the second latch part 4 arranged second wedge 18 interacting ramps 21, 22 form an undercut, which in a pressure direction containing the cutting plane an approximate circular arc shape 19 about the pivot axis 20 of the wing 6 of Window or the door has.

The mounting plate 7 is after FIG. 2 According to the invention, it is provided that the adjusting device 8 can be arranged laterally next to the wedge 5, ie not in the direction of pressure in front of or behind the wedge 5. For this purpose, the receptacle 9 of the adjusting device 8 is designed as a circular bore, which is arranged at the respective ends of the mounting plate 7 , A head portion 14 of the Exzenterspreizdübels 10 passes through the receptacle 9 playfully rotatably. Not shown engages the head part 14 in the receptacle 9 and is held by a positive connection. Likewise, but also not shown, the head part 14 can be riveted non-positively, so that the Exzenterspreizdübel 10 is further rotatably held in the receptacle 9. As a result, on the one hand, the width of the first Riegeteils 3 remain limited, on the other hand, a relatively wide configuration in the pressing direction of the wedge 5 is possible. Further, the fitting part 1 consisting of the mounting plate 7 and arranged on each side of the wedge 5 Exzenterspreizdübel 10 is easier and faster to install as a one-piece component.

For ease of design and connection during assembly of the mounting plate 7 with the Exzenterspreizdübel 10 is provided that the mounting plate 7 as in FIG. 2 has a gap 15 between the inside of the frame 2 and the side facing the mounting plate 7 for receiving a merging from the head part 14 Federal 17 of the Exzenterspreizdübels 10 has. By having as a stop collar 17, the Exzenterspreizdübel 10 can be precisely adjusted in its position. In addition, the gap 15 of the mounting plate 7 is partially filled by the adjustment and mounting position flush with the mounting plate 7, so that with attachment to the frame 2, a high tightening force of the fitting 1 is achieved while rotational inhibition and thus positional adjustment of the Exzenterspreizdübels 10.

For mounting the fitting part 1 in the frame 2, two holes 11 having a predetermined length spacing are provided. Simplified, the assembly of the first latch member 3 is characterized in that the Exzenterspreizdübel 10 after FIG. 5 a shaft 23, which is remote from its head part 14 free end 24 over a portion of its length at least once slotted with a longitudinal slot 25 and circumferentially has a chamfer 26 or a radius. Through the longitudinal slot 25, the shaft 23 is spring-loaded. In order to easily achieve a slight bias of the fitting part 1 in pre-assembled position in the frame 2, the diameter of the shaft 23 is slightly larger than the diameter of the bore 11 in the frame 2. By the chamfer 26 or the radius at the free end 24 of the shaft 23, the fitting part 1 can be adjusted automatically and inserted into the bore 11.

Before the mounting screws 28 fasten the fitting part 1 permanently on the frame 2, the mounting plate 7 can be adjusted in a pre-assembly in a simple manner by turning the Exzenterspreizdübel 10 within the bore 11 of the mounting plate 7 and the bore 11 in the frame 2 to pressure, the Rotary axes after FIG. 5 of the head portion 14 within the mounting plate 7 and the shaft 23 in the bore 11 are eccentric to each other. To FIG. 4 and FIG. 5 has the Exzenterspreizdübel 10 for Andrückverstellung the central bore 12, the after FIG. 2 for receiving a fastening screw 13 is formed and additionally has a Werkzeugingriffausnehmung 29. The Werkzeugingriffausnehmung 29 extends over a central portion of the central bore 12 and is formed as an internal hex recess. About a not shown lever tool, the Exzenterspreizdübel 10 are eccentrically rotatable in slightly biased mounting position, and thus cause a positional adjustment of the mounting plate 7 in the pressing direction.
Upon reaching the correct position, the final assembly of the fitting part 1 can be done by the fastening screws 13.

The fastening screws 13 are screwed into the central bore 12 of the Exzenterspreizdübels 10 for final assembly or previous Andruckverstellung. To avoid unevenness and to achieve a tight fit of the fitting part 1, the Exzenterspreizdübel 10, for example, after FIG. 5 in the head part 14 a recess 27 for the head part 28 of the fastening screw 13. With attachment of the latch part 3 by the fastening screw 13 is formed so in final assembly FIG. 1 with the mounting plate 7 and the Exzenterspreizdübel 10 a flush design.
Characterized in that the fastening screw 13 requires no further receiving bore in the first latch part 3, the first latch member 3 is not unnecessarily increased in length perpendicular to the pressing direction and thus in the embodiment unnecessarily, resulting in a complication and increase in the cost of construction of the first latch member 3 result Has. Due to the small configuration of the first latch part 3, the configuration of the second latch part 4 can be adapted in size, in particular in length.

The Werkzeugingriffausnehmung 29 forms a guide of the fastening screw 13 and is dimensioned slightly larger in diameter than the nominal thread diameter 31 of the fastening screw 13. This has the advantage that even with subsequent unscrewing of the fastening screw 13, the inner hexagonal recess 29 is intact and a Readjustment of the fitting part 1 can be operated by a lever tool.

To FIG. 5 the shaft 23 of the Exzenterspreizdübels 10 tapers towards the free end 24, but remains constant in the outer diameter constant. In the case of high burglarproof requirements, it may be advantageous to provide a taper 30. In this case, the taper 30 should be dimensioned smaller in diameter than the core diameter 32 of the fastening screw 13, which spreads apart with engagement of the fastening screw 13 in the shaft 23 in the preassembled state of the first latch member 3 on the frame 2 of the shaft 23 in the bore 11 of the frame 2 and thus produces a frictional connection of the first latch part 3 with the frame 2.

In order to meet the requirements of a high pressure force and a closing position of the window or door security against burglary, the mounting plate 7 is made of a metallic material or a combination between metal and plastic. The Exzenterspreizdübel 10 should be made of an elastic material, for example made of a plastic, since the shaft 23 of the Exzenterspreizdübels 10 is spread in the bore 11 of the frame 2 by the fastening screw 13 and jammed in the frame 2 or einpresst. But it is also conceivable to produce the Exzenterspreizdübel 10 of a metallic material, since the spreading of the shaft 23 is slightly.
On the Exzenterspreizdübel 10 formed shaft 23 also not shown barb-like projections can be attached, which cause a higher positive connection between the first latch part 3 and the frame 2.

Zeicherisch not shown but it is conceivable that for ease of design and connection in the assembly of the fitting part 1, the first latch part 3 and the second latch member 4 in the longitudinal direction and transverse to the fitting groove form symmetrically. Since the first latch part 3 and the second latch part 4 are already symmetrically formed transversely to the groove, it requires only a small design effort to achieve symmetry in the longitudinal direction of the fitting by the wedge 5 of the first latch part 3 according to the arc shape 19 on both sides to adjust the same is.
