Description

The invention relates to a hinge fitting of a rotary fitting or turn-tilt hardware for windows or doors according to the preamble of claim 1.

Hinge fittings of this type are already known. From the DE 26 23 140 A1 is a hinge connection with a two parts hingedly connecting hinge pin is known, which is brinbar from a dome position by axial displacement in a uncoupled position in which the two parts can be detached from each other. A first holding device ensures that a guided in one of the parts to be connected locking member engages resiliently in the two positions of the hinge pin in each case in a latching recess of the hinge pin. The detent recesses are tapered wedge-shaped at their mutually facing boundary surfaces and have in the uncoupling position of the hinge pin within one of the parts to be connected to the end of the adjacent detent recess to be latched on a wedge-shaped beveled boundary surface. Further, a further holding device is provided, consisting of a visible on the hinge pin holding element, which is brinbar with a holding counter-element in engagement, when the hinge pin is moved into the coupling position.

For mounting and dismounting of the joint connection two force storage devices are required, which in turn are designed differently. One of the power storage devices is a spring wire having a relatively complicated shape between the hinge pin and the frame abutment surface of the hinge joint. In this case, the spring wire engages in a one-sided conically beveled Rastausnehmungs- circumferential groove of the hinge pin and holds the hinge pin in a mounting position of the hinge connection. To achieve a joint connection of the joint parts, the hinge pin is moved further into a secure coupling position. The operational secured coupling position is not generated solely by the spring wire, but by a second spring which is arranged on the visible side at one of its free ends of the hinge pin, which adversely affects the appearance. Furthermore, the design is very expensive due to the complex production of the energy storage devices.

From the DE 195 21 539 A1 a scissors bearing, a rotary fitting or turn-tilt fitting for windows or doors is known, consisting of a bearing fork part, an insertable between the fork legs of the bearing fork part Lageraugenteil, a Lageraugenteil and the fork legs of the bearing fork part passing through the pivot bearing bolts and a bolt safety. Further comprising a arranged on the fork leg fuse element which is displaceable between a securing position with engagement in a recess of the pivot pin and a release position out of engagement with the latching recess and with a spring element for biasing the securing element in the securing position. In this case, the securing element is formed by a fork leg transversely to the pivot bearing pin axis movably mounted safety slide. Another disadvantage of this design is the optical design, since the bolt lock is arranged on the visible side and can be unlocked. Furthermore, two power storage devices are required to effect the securing of the scissors bearings, which has an adverse effect on the cost. In addition, the two-part design is complicated to use in a possible disassembly, since the scissor bearing is unlocked at two points simultaneously with a tool engagement.

The invention has for its object to avoid these disadvantages and to develop a hinge fitting of the type mentioned in such a way that it is inexpensive to manufacture and at the same time ensures high security against falling out of the bearing pin.

To solve this problem, a hinge fitting of a rotary fitting or turn-tilt hardware for windows or doors is provided according to the features of claim 1, with a bearing fork part and an insertable in the bearing fork part Lageraugenteil, wherein the bearing fork part and the Lageraugenteil penetrated by a bearing pin are. In this case, a bolt safety device is arranged with a securing element on the bearing fork part, which is guided between a securing position with engagement in a latching recess of the bearing pin and a release position out of engagement with the latching recess in a recess, transversely to the axial length of the bearing pin. For biasing the securing element in the securing position an energy storage device is provided. At one of its free ends of the bearing pin a flattening is formed, wherein the securing element in the securing position on the Bearing side directed bearing pin abuts one end of the flattening and has on the side facing the free end of the bearing pin side up to the bolt outer diameter reaching bevel. The fact that in the storage fork part, the securing element and the energy storage device are different components, thus manufactured on the type of stress, high security against falling out of the bearing bolt is guaranteed. Furthermore, the design of the securing element allows the user to easily handle the assembly or disassembly of the sash to the frame of the window or door.

It is further provided according to claim 2, that the bolt lock is formed from the securing element and the power storage device. The fuse element can be easily adapted to the bearing pin by the flexible choice of material of the form and the necessary stress. The shape and type of the energy storage device are easier to choose. The energy store selected here as a spring plate or leaf spring can also be selected as a compression spring. The transfer of the spring action of the energy storage device to the bearing pin, also finds by the separate conception easier tuning.

In a further development of the invention, it is provided according to claim 3, that the securing element and the power storage device are arranged captive in a form-fitting recess facing away from a rear frame abutment surface of the bearing fork part. With this configuration, the appearance of the hinge fitting remains on the visible side with simultaneous pin retention. Further, even with a loosening of the connection, for example, a rivet connection of the bolt safety to the storage fork part further given the security that the bolt safety can not fall out of the storage fork part and the effect loses, since the frame abutment surface rests flush with the frame.

In a further embodiment of the invention is provided according to claim 4, that the power storage device is preferably formed as a spring plate and arranged in the recess on a gradation between the securing element and the frame-side stop surface of the storage fork part. The material selection of the force storage device has an advantageous effect on the Production costs. Further, the spring plate is positioned in the recess on a gradation and held against rotation, so that the securing element only requires a vertical attachment.

In a further development of the invention is provided according to claim 5, that the force storage device forms an asymmetric outer edge which rests positively in the recess on the step, wherein in the middle of the power storage device for securing element pointing cut-out leg is bent at its free end to form a dome , The design receives a backlash-free pin securing, which has an advantageous effect on the mode of action of the spring force, which transfer the pulse without delay to the fuse element. Due to the asymmetric outer edge of the positive connection, a faulty mounting is excluded, since the force storage device can be mounted only from one side. Thus, the assembly is simplified and process reliable and cost-effective due to the time savings. Simple in the production and cost can be adjusted with the bent legs depending on the angle a dimensional adjustment of the size of the distance to the fuse element, the spring force. The dome is particularly suitable for reducing the frictional resistance during assembly or disassembly from the spring plate to the securing element.

In order to ensure a perfect spring force transmission of the spring plate to the securing element, the securing element in a further advantageous embodiment according to claim 6 on the side facing the force storage device side a groove which receives the leg of the energy storage device leader. Thus, a snagging of the leg by the guide in the groove remains, even if one of the components should rotate, for example, due to inaccurate production.

In addition, it is further provided according to claim 7, that the securing element has an asymmetrical circumference, which engages positively in the recess and reaches up to the passage opening of the bearing fork part for the bearing pin. Due to the asymmetrical circumference of the securing element and the adaptation to the recess in the storage fork part, a faulty assembly is excluded because the securing element can be mounted only from one side. Thus, the assembly is simplified and process-safe and due to the Time savings cost-effective. In order to achieve an effective but inexpensive securing element, the width of the securing element corresponds approximately to the diameter of the bearing pin.

In a further development of the invention is provided according to claim 8, that the bearing pin tapers from the outer diameter to the end of the flattening at an angle and another portion forms a fold, which is formed perpendicular to the flattening. In order to obtain a functionally reliable hinge fitting in the assembled state of the window or the door, so that the bearing pin is secured in a predetermined position against falling out of the storage fork part, the bearing pin has the fold behind which the fuse element is held kraftbeaufschlagt. The taper from the outer diameter to the flattening simplifies the engagement of the bearing pin during assembly and favors the release upon engagement of a tool in the through hole of the bearing fork part of the bearing pin for disassembly. Another advantage is the acoustics of the detent. So the security is given that a secure locking of the bearing pin is done.

In order to achieve a simple mounting of the bearing pin is provided according to claim 9, that the bearing pin has a chamfer at the end facing away from the bolt safety. The bearing pin overcomes the bolt lock without catching and a great deal of effort. It is particularly optically advantageous if the respective ends of the bearing pin are flush with the bearing fork part.

In a further embodiment of the invention is provided according to claim 10, that the bearing pin in the axial length on the side facing away from the bolt securing a flattening and the reduced cross-section of the passage opening of the bearing fork part is adapted for a first portion, wherein the second portion of the bearing pin and the passage opening is formed in a circular arc in cross section. It is advantageous by the flattening that the bearing pin can not rotate within the passage opening of the storage fork part. The arrangement for securing the bearing pin on the opposite side is thereby fixed. In order to fix the position of the arrangement for securing the bearing pin in the axial direction, is at the end of the arrangement of Pin lock the flattening of the bearing pin lifted again and adapted to the diameter of the passage opening.

The foregoing embodiment also causes a simple assembly of the bearing pin, since only in the correct installation position of the bearing pin can be mounted in the bearing fork part.

To disassemble the hinge fitting and thus the sash to the frame of the window or the door, the securing position can be canceled with engagement of a tool between the through hole of the bearing fork part and the flattening of the bearing pin, so that the bearing pin is displaced into a release position out of engagement with the recess , It is particularly advantageous in this case that the engagement for unlocking takes place through the existing passage opening. Other visible changes to accommodate the pin safety are not necessary. In addition, the bolt safety is completely concealed.

In the figures, a hinge fitting 1 a turn-fitting or turn-tilt hardware for windows or doors is shown. The hinge fitting 1 is connectable to a frame, not shown, and a sash of the window or the door, wherein the illustrated bearing pin 4 with the bearing frame attached to the frame part 2 and arranged on the sash frame bearing suction part 3 causes the connection. The bearing pin 4 is inserted in this embodiment on the vertical frame fixed bearing fork part 2 from below through a through hole and through a through hole of the vertically arranged Lageraugenteils 3 through. The bearing suction part 3 is provided in the case of a turn-tilt fitting on the fixed frame-side end of a stay-arm or a release device. In the case of a rotary fitting the bearing suction part 3 is fixed directly to the casement.

The hinge fitting 1 can be used for right or left stop. It is only important to ensure that the bearing pin 4 is inserted separately from below into the through hole of the storage fork part 2, ie with his in the Fig. 1 to 6 upper end 25 ahead. The opposite end 9 can not be inserted, since the bearing pin 4 in the axial length on the bolt lock 5 side facing away from a flattening 27 and the reduced cross-section after Fig. 3 to 6 the passage opening of the bearing fork part 2 and the Lageraugenteils 3 is adapted for a first portion 28, wherein the second portion 29 of the bearing pin 4 and the through hole is formed in cross-section arcuate.

The mounting choice has the great advantage that the bearing pin 4 is not plugged in the assembly or disassembly in the already very cramped space between the hinge fitting 1 and the mounting hole or wall opening in the upper corner of the window or door.

The bearing fork part 2, the bearing eye part 3 and the penetrating bearing pin 4 are provided with a pin safety 5. This serves to the bearing pin 4 in his in Fig. 3 shown axial normal position to hold, which he then occupies when the sash is completely assembled to the frame, so the bearing suction part. 3 is rotatably mounted on the bearing yoke part 2 via the bearing pin 4. However, this position also assumes the bearing pin 4 when the storage fork part 2 is stored or transported independently of the bearing suction part 3 or is preassembled on the frame.

In order to prepare the stop of the sash to the frame of the window or the door, the bearing pin 4 is pulled out of the upper region of the bearing fork part 2 so far that the space for insertion for the bearing suction part 3 is free. In this axial mounting position of the bearing pin 4 is held by the pin fuse 5 and the bearing pin 4 arranged on both sides conical circumferential groove 30 latching. With alignment of the bearing fork part 2 to the bearing eye part 3 of the bearing pin 4 is again inserted from the detent addition into the assembly latching detent.

The releasable locking in the mounting position makes it easier for the fitter to mount the wing, since heavy wings often have to be held by the fitter with one hand. Introducing a separate bearing pin would significantly complicate the assembly process.

Consequently, the assembly and disassembly by a simple operation of the bearing pin with integrated pin safety of particular advantage.
The bolt safety 5 is after Fig. 1 to 7 Among other things, from a securing element 6, which is guided between the securing position with engagement in a latching recess 7 of the bearing pin 4 and a release position out of engagement with the latching recess 7 in a recess 15, transversely to the axial length of the bearing pin 4 displaced. Furthermore, the bolt safety device 5 has an energy storage device 8 for biasing the securing element 6 in the securing position.

In order to keep the securing element 6 on the bearing pin 4 leader, a flattening 10 is formed at one of the free ends 9 of the bearing pin 4. The flattening 10 corresponds approximately to the width of the securing element 6 and forms a rectangular surface. The flattening 10 is used in the installed state as a system for the securing element 6, wherein the securing element 6 is arranged in the securing position on the side facing the bearing pin 4 side 11 at the end 12 of the flattening 10.

For insertion of the bearing pin 4 in the through hole of the storage fork part 2, for simplifying overcoming the kraftbeaufschlagten pin fuse 5 at the free end 9 of the bearing pin 4 side facing up to the bolt outer diameter reaching chamfer 13 is formed. The chamfer 13 has the further advantage that with the introduction of a tool 31 for disassembling the tool 31 itself is guided by the flattening 10 up to the pin fuse 5 and the bolt lock 5 triggers on contact with the securing element 6 via the chamfer 13.

For assembly, the pin lock 5 engages on the back ie on the non-visible side of the frame-stop surface 14 positively in a recess 15 of the bearing fork part 2 and is held there captive.
To Fig. 7 the power storage device 8 is preferably designed as a spring plate. In order to complete flush with the frame stop surface 14 and to avoid unevenness in the attack of the storage fork part 2 to the frame, a step 16 is provided in the recess 15, which receives the spring plate positively and secures against rotation. Preferably, the force storage device 8 forms an asymmetrical outer edge, which is adapted to the shape of the step 16. A wrong assembly is to be ruled out because the spring plate can be inserted only in the correct position in the gradation 16. To form the spring force, the energy storage device 8 in the middle and the securing element 6 facing a cut-out leg 18. The leg 18 is bent in accordance with the distance of the support from the gradation 16 to the securing element 6 far enough that the free end 19 rests against the securing element and a noticeable spring effect is achieved in the installed state. A arranged at the free end 19 dome 20 after Fig. 3 and Fig. 7 ensures a virtually smooth contact with the securing element 6 in a groove 18 having groove 21 which receives the leg 18 leader at the same time.

The assembly of the securing element 6 in the recess 15 is simplified by an asymmetrical circumference 22. The securing element 6 can be fitted only from the right side into the form-fitting counterpart of the recess 15.

To achieve full efficiency of the bolt lock 5, it is of particular advantage if the securing element 6 extends through the recess 15 through to the passage opening of the storage fork part 2. The chamfer 13 having the engagement of the tool 31 can thereby be made large, which causes easier disassembly. At the same time, the bevel 13 also advantageously cooperates with the chamfer 26 during assembly of the bearing pin 4.

At the end 12 of the flattening 10, a first portion is provided with an angle 23 which tapers from the outer diameter to the end 12 and merges into a second portion with a perpendicular to the flattening 10 arranged fold 24. The fold 24 is designed in height so in that the securing element 6 engages in a secured position without requiring actuation of the bolt safety device 5 and precluding unintentional release of the safety bolt 5. The height of the fold 24 is after Fig. 7 In addition, according chosen so that a release can also be done with possible dimensional deviations, for example, by the components in each case.

The insertion of the bearing pin 4 in the bearing fork part 2 and the adjustment of the mounting position with alignment of the bearing fork part 2 to the bearing eye part 3, wherein the bearing pin 4 is again inserted from the first detent locking into the mounting detent is to be inserted through a at the end of the 25 Bearing pin 4 having chamfer 26 greatly facilitated. An optical advantage gives the hinge element 1 in that the respective ends 9, 25 with the storage fork part 2, as in Fig. 3 and Fig. 5 shown, flush with the surface. Due to the flush design of the bearing pin 4 and the concealed bolt lock 5 acts the hinge fitting on the one hand not oversized, on the other hand unwanted opening the Botzensicherung 5 is difficult because there is no visible attack surface, for example, a tool.

To Fig. 3 to Fig. 6 the bearing pin 4 in the axial length on the side facing away from the bolt lock 5 a flattening 27, which is adapted to the reduced cross-section of the passage opening of the bearing fork part 2 and the Lageraugenteils 3 for a first portion 28. In a second portion 29 of the bearing pin 4 of the passage opening to the end of the bearing fork part 2 out in cross-section again arcuate. With this configuration can be the bearing pin 4 only from one side and in an orientation in the passage opening of the bearing fork part 2 and the Lageraugenteils 3 and is held in a predetermined position from the storage fork part 2 to the bearing pin 4. The responsible fitter assembly of the hinge fitting 1 is much easier.
