Description

Tape for hinge-jointed connection of a

Wing with a frame

The invention relates to a hinge for hinge-jointed connection of a wing to a frame, with a hinge axis defining the hinge axis, at least one region with a circular cross-section and a first hinge means having hinge pin, with a wing hinge part that can be fastened to the wing, with one the frame attachable frame hinge part, wherein at least one of the wing hinge part and the frame hinge part has a hinge axis extending in the Rich direction hinge pin receptacle, and provided within the hinge pin receptacle, second engagement means with which the first engagement means of the hinge pin are directly or indirectly engaged.

Such a tape is known from EP 1 666 688 A1. In this known band, the first comprise a toothing which extends over a part of the circumference of the band bolt and projects from it. The longitudinal extent of this toothing runs parallel to the hinge axis. The second grip means comprise teeth provided within the hinge pin receptacle. The hinge pin receptacle is elongated in cross section. The toothing, which forms the second engagement means, is provided on a wall of the hinge pin receptacle, which extends in the longitudinal direction of the elongated cross-section and springs back from it, ie incorporated into this. For the purpose of adjustment in a direction perpendicular to the hinge axis of the hinge axis, the hinge pin is displaceable in the longitudinal direction of the long, hole-shaped cross section, wherein it rotates due to the engagement of the toothing forming the first and second engagement means about itself and always remains aligned in the direction of the hinge axis. The first and second engagement means prevent the hinge pin from tilting in the hinge pin, making it difficult or even impossible to hook in a wing. Although the hinge known from EP 1 666 688 A1 enables the wing to be hooked in without difficulty and also an adjustment thereof perpendicular to the hinge axis, which is also referred to as “horizontal adjustment”. However, it has been shown in practice that the The ability to mount tapes can be difficult due to the toothing of the tape pin, especially if the tapes are more than two parts and / or adjustable in two or three spatial directions and require the use of bearing bushes through which the tape pin is used when mounting the tape or the wing has to be inserted.

The invention is therefore based on the object of further developing the tape known from EP 1 666 688 A1 in such a way that it is improved with regard to the aforementioned disadvantage.

This object is achieved by a tape with the features of claim 1.

According to the invention, the first engagement means have at least one recess which springs back from the cross section of the hinge pin and the second engagement means have at least one projection which engages in the recess. In other words, unlike in the prior art, the first engagement means no longer protrude radially beyond the cross section of the hinge pin, but are incorporated into the hinge pin as seen from the cross section. Due to this measure, if the permanent guidance of the hinge pin is completely retained in the hinge pin receptacle against tilting, there is the possibility of also leading the area of the hinge pin provided with the first engagement means through bearing bushes which are adapted to the cross section of the hinge pin in such a way that it is in this bearing bushes, for example, is slidably mounted and rotatable. In the prior art, this possibility exists due to the jumping means of intervention. Since the second engagement means protrude from the hinge pin holder, there are no depressions which weaken the hinge part. The resilience of a band is therefore increased due to the training according to the Invention.

In order to enable a play-free engagement of the first and second engagement means and a play-free displacement of the hinge pin perpendicular to the hinge axis, in a preferred embodiment of the hinge according to the invention, the trough is part of a toothing that springs back from the cross section, and the projection is part of a projecting, complementary Ver perforation.

A sufficient displaceability of the hinge pin in the hinge pin holder is ensured if - as preferred - the recessed toothing extends over part of the circumference of a region with a circular cross section, the hinge pin holder has an approximately oblong cross section with two parallel longitudinal walls, and the protruding toothing is provided on one of the longitudinal walls. In this case, the longitudinal wall, which is opposite to that which has the projecting toothing, form a straight guide, on which the hinge pin slides in a displacement perpendicular to the hinge axis for the purpose of horizontal adjustment. The hinge pin will move on a straight line that is perpendicular to the hinge axis due to the linear guidance - within production-related tolerances, which enables a particularly precise horizontal adjustment of the sash in the frame.

In order to facilitate the horizontal adjustment process of the wing in the frame, the hinge according to the invention preferably has displacement means with which the hinge pin can be displaced within the hinge pin while rotating transversely to the hinge axis, and fixing means with which the hinge pin can be fixed in a desired position in the hinge pin holder is.

The displacement means preferably comprise a device for attaching a turning tool on at least one longitudinal end of the hinge pin. The device for attaching a turning tool is particularly preferably adapted to the turning tool in such a way that the angular position of the turning tool is in a predetermined correlation to the position of the hinge pin in the hinge pin holder. Due to this measure, for example, the angular position of the turning tool can be used to easily identify whether the hinge pin is located in the hinge pin bushing in a central position or in a position displaced by this with respect to the possible horizontal adjustment. The operability can also be facilitated by the fact that the band according to the invention is always delivered with the band pin in the middle position. The operator can then position the turning tool in the known angular position.

The device for attaching a turning tool can preferably have an internal multi-tooth or an internal full round, preferably an internal hexagon or an internal twelve-sided or an internal hexagon or internal twelve-round. The use of an inner twelve-sided or an inner twelve-round is particularly advantageous if, for example, the turning tool can only be rotated by relatively small angles because of limited space, since it can be reattached already after an angle rotation of 30 °.

A development of the band according to the invention is particularly preferred, in which the fixing means have a clamping screw and a threaded bore extending parallel to the coulter axis for screwing in the clamping screw on at least one longitudinal end of the band bolt. This design of the fixing means regularly allows easy operability, since the end faces of the hinge pin are regularly accessible when using the strap. In addition, there are no necessary access openings in the wing hinge part or frame hinge, which can lead to mechanical weakening and to an increase in the manufac turing effort in other designs of the fixing means.

The clamping screw preferably comprises a clamping surface which can be brought into operative connection with a counter-clamping surface provided on the wing hinge part or on the frame hinge part. In the simplest case, the clamping surface is from the flat underside of the thread facing the clamping screw Formed the head of the clamping screw. You can - depending on the design of the counter clamping surface - not even, for example, spherical or conical. It can also include friction means, such as corrugations to bring about a reverse rotation and increase the friction at a specific tightening torque to improve the fixing effect.

In a very particularly preferred embodiment of the band according to the invention, the band bolt has a peripheral collar. The at least one recess to be recessed is provided in a region of the hinge pin that extends in one direction from the circumferential collar. The fixing means are provided on that longitudinal end of the area having the at least one trough. In this particularly preferred embodiment of the band according to the invention, a region of the band bolt which has a cylindrical cross section extends from the circumferential collar in the other direction. The displacement means are then provided at the longitudinal end of this area. The operability of the belt is particularly easy due to this preferred embodiment, since an operator knows which side he has to apply the turning tool to. The operator can also easily maintain a desired horizontal adjustment position of the sash once reached in the frame by holding the turning tool in place before the fixation is effected by turning in the clamping screw.

The embodiment of the band according to the invention, designated 100 as a whole in the drawing (hereinafter referred to briefly as “band 100”), comprises a frame band part 1 that can be fastened to a frame (not shown in the drawing) with fastening screws 2 and dowel pins 3 and one on a frame that is also not shown in the drawing Sash can be fastened by means of fastening screws 4 and dowel pins 5 5.

The frame hinge part 1 and the wing hinge part 6 are connected to one another in a hinge-like manner about a hinge axis S by means of a hinge pin 7, the central longitudinal axis of the hinge pin 7 defining the hinge axis S.

As can be seen in particular from FIG. 2, which shows the wing hinge part - in sections - in a single illustration, the wing hinge part 6 has a crosswise cut slot-shaped hinge pin receptacle 8. It is limited by narrow circular walls 9, 10 and flat longitudinal walls 11, 12.

From the longitudinal wall 12 protrude two projections 13 which engage with two recessed troughs 14 incorporated into the cross section of the hinge pin 7 when the hinge pin is inserted into the hinge pin receptacle 8. The projections 13 and the troughs 14 extend parallel to the hinge axis S. The troughs 14 form first engagement means 15 and are part of a recessing the toothing Z of the hinge pin 7, the projections 13 second engagement means 16 and are part of a projecting toothing V of the wing hinge part. The hinge pin 7 is in positive engagement with the wing hinge part 6 via the first and second engagement means 15, 16.

As is particularly apparent from Fig. 1, a shift of the Bandbol zens 7 along the cross-sectionally elongated hinge pin receptacle 8, d. H. in the direction of the double arrow D in Fig. 1, in which the Bandbol zen 7 is rotated. To initiate this, the band bolt 7, as can be seen in Fig. 3, 4, 10, 11 and 14, on a longitudinal end 17 of its resting in the frame band part 1 area 18, a device 19 for attaching a turning tool, not shown in the drawing , which is formed as an internal hexagon in the illustrated embodiment. A suitable turning tool would include a complementary external hexagon, for example, would be designed as a so-called Allen key. The win kelstellung, under which the device for attaching a turning tool, here the hexagon, is provided on the hinge pin 7, is in a predetermined correlation to the position of the first engagement means 15 and thus to the position of the hinge pin 7 in the hinge pin receptacle 8. The correlation is chosen for example so that the 90 ° leg of a conventional Allen key runs parallel to the plane of the frame when the hinge pin 7 is in the middle position shown in FIG. 1 in the hinge pin receptacle 8.

As can be seen in particular from FIGS. 5, 6 and 10, from the front side there is an area 20 of the hinge pin 7 which is the first engagement means 15 comprises an internal thread 21 incorporated. It is used to screw in a clamping screw 22, which is shown in detail in FIGS. 7 and 8.

The clamping screw 22 has a threaded shaft 23 and a head 24. Between the threaded shaft 23 and the head 24, a peripheral collar 25 is seen before, which protrudes radially over the circumference of the head 24. The underside of the circumferential collar 25 forms a flat clamping surface 26, which can be provided with a friction device, not shown in the drawing, in order to achieve higher clamping forces and to bring about an anti-rotation device.

The hinge pin 7 also has a radially projecting circumferential collar 28 between its regions 18 and 20. In the wing hinge part 6 8 recesses 29 are provided at the ends of the hinge pin receptacle, de de only the one facing the viewer can be seen in Figures 1 and 2. The peripheral collar 28 of the hinge pin 7 is positioned such that, by tightening the clamping screw 22, a clamping fit between the clamping surface 26 and a clamping surface 30 formed by the circumferential collar 28 of the hinge pin 7 by supporting the clamping surface 26 and the clamping surface 30 on counter clamping surfaces 27 of the respective recess 29 is effected.

With the band 100 according to the invention, an adjustment and fixing of the sash in the frame is possible in a particularly simple manner in that, after loosening the clamping screw 22, the hinge actuation of the hinge pin 7 required for the adjustment takes place by engagement of a turning tool in the hexagon socket, the fixing in the adjustment position by subsequently tightening the clamping screw 22 while holding the hinge pin 7 in its position required for the adjustment. As shown in particular Fig. 12 shows, the first engagement means 15 are not over the cross section of the hinge pin 7. The area 20 of the hinge pin can also be pushed through with bearing sleeves adapted to its cross section, if necessary, which - depending on the design of further components of a hinge - considerably simplifies its assembly.
