Abstract

The strip arrangement (100) comprises a cover (12) which is only joined to the strip part (10) by insertion parallel to the strip journal (30). The strip part is held horizontal in all directions by the engagement of rear recesses (16-18,22,23). The axis of a pin (50) intersects the journal. The hinge section (6), the strip journal and the bush (40) have perforations (24,26,28) which align with the axis of the pin by an opened wing (2). The strip journal is turned by a closed wing through 90 deg. and blocks the hole to the pin.

Description

Tape for doors, windows and the like

The invention relates to a tape of the type corresponding to the preamble of claim 1.

Such a hinge is the subject of DE-GM 93 15 327, which is part of the state of the art but was not previously published. In this hinge, the spring-loaded pins are arranged perpendicular to the frame or sash surface. The hinge parts of the two hinge parts lie one above the other and are offset from the contact surface of the respective hinge part to the front, i.e. away from the fastening surface on the frame or sash, so that a space remains behind the hinge part through which access to the respective fastening part is possible from its inner side surface. A tool can be inserted through a hole made at this point in the area of the tip of the spring-loaded pin engaging in the fastening part, with the help of which the tip of the pin can be pushed back and the locking effected by the pin can be released. Access for the tool, which in turn can be a pin with a bevelled, wedge-like front end, is from the area of the shadow groove of the door or window, because the hole must run from the inner side surface of the fastening part diagonally forwards away from the fastening surface.

The profile systems supplied by the individual manufacturers of the frame profiles for the fixed frame and the sash are very different in their design and dimensions, so that the inner side surface of the fastening part of the respective hinge part on the frame profiles can also be located in completely different places, viewed horizontally. In some cases, when the inner side surface is far away from the adjacent edge of the shadow groove, the introduction of the release tool for the locking mechanism is difficult, if not impossible.

The same problem occurs if the angled hole is not used to remove a spring-loaded pin, but rather to remove a screw that engages a threaded hole in the cover of the relevant hinge part. Here too, the screw head may be difficult to reach depending on the position of the inner side surface of the fastening part.

There is a need to be able to release such a snap-in locking mechanism if necessary without having to use force or damage to the cover. This can be the case, for example, if the fastening screws of the hinge parts need to be tightened.

The invention is based on the object of designing a band of the type in question in such a way that the position of the band relative to the profile system is not important for releasing the locking mechanism.

This object is solved by the invention set out in claim 1.

Because the hole for reaching the end of the spring-loaded pin in the horizontal plane is not passed past the hinge pin but through it, the hole can, for example, run approximately parallel to the fastening surface and is then always accessible, regardless of the position of the hinge on the profile system.

Of course, the installation of the slanted hole in the design according to DE-GM 93 15 327 in the inner side surface of the fastening part, i.e. behind the hinge part, has the function of making this hole inaccessible when the sash is closed. This safety function is also intended to be present in the invention and is ensured by the arrangement of the hole in the hinge pin, which rotates when the sash is closed so that the passage for a tool that can be placed against the end of the spring-loaded pin is blocked. The prerequisite is therefore that the hinge pin is attached in the other hinge part in a rotationally fixed manner and rotates when the sash is pivoted.

Preferably, according to claim 2, the pin is embedded in the front side of the cover facing the hinge pin.

Claims 3 and 4 specify special designs of the undercuts which result in the complete horizontal fixing of the cover. The edge rib of the cover interacts with the projection of the band part in such a way that the projection prevents the cover from being led out of the groove of the band part and thus supplements the horizontal fixing on the flanks of the groove by a fixing in the direction of the groove depth.

All that remains for complete fixation is to lock the displacement parallel to the hinge pin, i.e. parallel to the edge rib and the groove, which is provided by the snap-in pin (claim 3).

The fixing according to claim 3 can be supplemented by designing the cover as an angle part. The angle part covers the front and the outer side surface of the fastening part and thus visually presents a closed surface. However, it can also additionally contribute to the fixing in the horizontal direction with its other leg.

The design is such that all parts involved in the external shape of the band are made of strand

presses parallel to the hinge pin. This not only simplifies production, but also allows the parts to be designed in such a way that they can be brought into engagement with one another by pushing them into one another parallel to the hinge pin, so that the undercuts come into effect purely by pushing them in.

An embodiment of the invention is shown in the drawing.

Fig. 1 shows a front view of a band, partly in section parallel to the mounting surface;

Fig. 2 shows a view of the upper band part of Fig. 1 from the right, partly in section along the line II-II in Fig. 1;

Fig. 3 shows a horizontal section through the belt of Fig. 1 along the line III-III in Fig. 1;

Fig. 4 shows a corresponding section with the hinge in the position corresponding to the opened wing? Fig. 5 and 6 show enlarged representations of the spring-loaded pin.

In Fig. 1, 3 and 4, a fixed frame 1 and a casement frame 2 can be seen, which can consist of aluminum profiles, for example, and are only indicated schematically. They are pivotably connected to one another by a band 100. The band 100 comprises a frame band part 10 and a casement band part 20, which are pivotably connected to one another by a band pin 30 with a hinge axis 7 that is vertical in the operating position. As can be seen from Fig. 1, the casement band part 20 is supported on the frame band part 10 via a weight-transferring and friction-reducing disk 41. The band pin 30 is mounted in the frame band part 10 in a non-rotating band pin bushing 40 and continues into the casement band part 20 and is held there in a rotationally fixed manner.

The frame band part 10 comprises a fastening part 4 which is adjacent to the front vertical flat fastening surface 3 of the fixed frame 1 and which is

has a rear flat contact surface 5 that rests on the fastening surface 3. A hinge part 6 is connected in one piece to the fastening part 4, which is horizontally offset from the fastening part 4 and has a cylindrical recess 9 in which the hinge pin 30 is arranged in an eccentric hinge pin bushing 40, i.e. the cylindrical outer peripheral surface and the cylindrical inner peripheral surface of the hinge pin bushing 40 have axes that are laterally offset from one another by the amount of eccentricity. Depending on the rotational position of the hinge pin bushing 40, an adjustment can be made. The hinge part 6 is also displaced forwards from the fastening part 4, i.e. away from the fastening surface 3, and in the middle its rear protrudes from the fastening surface 3 by the distance 8 (Fig. 3).

In the exemplary embodiment, the fastening part 4 has an approximately rectangular cross-section with a flat front side 11 parallel to the contact surface 5, against which a cover, designated as a whole with 12, rests with its flat rear side 13.

The parts 4, 6 on the one hand and 12 on the other hand are pressed from an aluminum material strand, whereby the extrusion direction runs perpendicular to the plane of the drawing according to Fig. 3, so that the parts have a constant cross-section in the vertical direction (in the assembled state) as predetermined by the production.

In the exemplary embodiment, the cover 12 is designed as an angle piece with the legs 12' and 12". The leg 12' assigned to the front side 13 of the fastening part 4 has approximately the cross section of a right-angled triangle, one of whose legs forms the front side 14 of the cover 12 facing the hinge pin 30. Along the front side 14 extends an edge rib 16 which projects from the underside 13 of the cover 12 and engages in a corresponding groove 17 in the front side 11 of the fastening part 4. Opposite the groove 17 on the outside is a projection 18 of the hinge part 6 or hinge part.

-β-10,
which overlaps the edge of the front side 14 there. The leg 12' of the cover 12 can therefore only be inserted vertically or parallel to the hinge pin 30 into the groove 17 and under the projection 18. After that, the cover 12 can no longer be displaced horizontally in any direction.

The fastening of the hinge parts 10 _and 20 is carried out by means of fastening screws 15, which have a head and in the embodiment are designed as polygon socket screws. They are screwed from the front through the fastening part 4 into threaded bushings or threaded parts (not shown) in the interior of the profile forming the fixed frame 1, which are seated from the inside against the rear of the profile wall forming the fastening surface 3. So-called centering bushings 36 are used to fix the frame hinge part 10 to the fixed frame 1 parallel to the fastening surface 3, which surround the fastening screws 15 and engage both in the frame 1 and in the fastening part 4.

Normally, the leg 12' of the cover 12 would be sufficient to cover the heads of the fastening screws 15. However, it would be possible to penetrate between the surfaces 11 and 13 from the left with a tool as shown in Fig. 3 and to exert large destructive forces due to the large lever arm. For this reason, the cover 12 is pulled around the fastening part 4 and covers the outer side surface 19 of the fastening part 4 with its other leg 12" which runs essentially at right angles to the leg 12'. As a result, there is no longer a gap between the cover 12 and the fastening part 4 that can be reached from the front. Close to the free edge of the leg 12", an edge rib 22 extends parallel to it and engages in a corresponding groove 23 of the fastening part 4. This further improves the definition of the horizontal plane.

To completely fix the cover 12, it now needs to be locked in the height direction,

i.e., according to Fig. 3, perpendicular to the plane of the drawing. A spring-loaded pin, designated as a whole with 50, is used for this purpose, which is arranged in a recess 21 of the face 14 with an axis perpendicular to the face 14. The pin 50 can be pushed back into the face 14, which makes it possible to slide the cover 12 in, according to Fig. 3, perpendicular to the plane of the drawing. When the cover 12, the height of which corresponds to the height of the band part 10, has reached the correct height, the pin 50 protrudes into a hole 24 in the wall 25 of the hinge part 6 opposite the face 14, which locks it in place. The hole 24 goes horizontally and approximately parallel to the fastening surface 3 through the hinge part 6.

In order to be able to release the locking mechanism parallel to the hinge pin and to push the pin 50 back into the surface 14, not only does the bore 24 go all the way through the hinge part 6, but the hinge pin bushing 40 has openings 26 at the appropriate height, offset by 90° from one another, which are aligned with the bore 24. In addition, the hinge pin 30 also has an opening 28 at the appropriate height in the form of a transverse bore, which can be aligned with the openings 24, 26 when the hinge pin 30 is at the appropriate angular position, as shown in Fig. 4.

The diameter of approximately 3 to 5 mm of the openings 24, 26, 28 is determined by the fact that a pin-like tool W for pressing the pin 50 into the end face 14 must be able to pass through easily.

The arrangement is such that when the sash is closed, the opening 28 of the hinge pin 30 is perpendicular to the sash surface, as shown in Fig. 3. The pin 50 is then normally no longer accessible from the outside. When the sash is closed, it is not possible to push a tool through the holes 24 and 26 from the right as shown in Fig. 3 to the free end of the pin 50 in order to push the latter into the front face 1.

and release the locking mechanism of the cover 12. This means that there is burglary protection, even though the right end of the hole 24 is freely accessible.

When the sash is opened, the hinge pin 40 rotates with the sash hinge part 20 into the position shown in Fig. 4, in which the openings 24, 26, 28 are aligned and a tool W can be inserted to press down the pin 50. The position of the frame hinge part 10 relative to the flank 31 of the shadow groove 32 is not important here, unlike in the case of conventional burglar-resistant fastenings of covers, which require actuation by means of oblique holes corresponding approximately to the dot-dash line 33 in Fig. 4.

The sash hinge part 20 is horizontally adjustable relative to the sash 2. The two fastening screws 15 arranged one above the other engage countersunk in a clamping piece 34, which in turn is arranged countersunk in a corresponding recess 35 in the sash hinge part 20 and rests on the floor. The screws 15 pass through grommet-like projections 38 on the underside of the clamping piece 34 facing the sash 2, which protrude over the underside of the sash hinge part 20 and perform the function of the centering sleeves 36. They therefore fix the clamping piece 34 to the sash in the sash plane. The projections 38 pass through the bottom of the recess 35 in parallel horizontal slots 37. The sash hinge part can therefore be displaced horizontally relative to the clamping piece 34 fixed to the sash 2 for the purpose of adjusting the sash 2 relative to the frame 1. The sash hinge part 20 is held in place by clamping the bottom of the recess 35 between the clamping piece 34 and the fastening surface 3 when the screws 15 are tightened. The displacement can be brought about when the fastening screws 15 are tightened by turning a screw 42 supported horizontally at both ends in the recess through an opening 43 in the outer lateral boundary of the recess 35.

The area of the clamping screws 15 is also covered by a cover 45 on the sash hinge part 20, which can be fastened in the same way as the cover 12 of the frame hinge part 10, but also in a different way.

In Fig. 5 and 6, the spring-loaded pin 50 is shown enlarged in its surroundings. It is arranged in a hole 21 in the front side 14 of the leg 12' of the cover 12. In the embodiment, the axis of the hole 21 runs through the hinge axis 7. It can also run slightly diagonally or perpendicularly to the frame surface. In any case, the pin 50 is aligned with the openings 24, 26, 28 and the hinge pin 30 must be cut so that it can develop its locking effect shown in Fig. 3.

The bore has a flat countersink 44 in the front side 14. The pin, designated as a whole with 50, comprises a pot-shaped container 46 with a radially beaded edge 47, which lies in the countersink 44. At the transition of the edge 47 into the cylindrical part of the "pot" there is a radially inwardly projecting constriction

48, behind which the protruding edge

49 of a cylindrical, cap-shaped locking pin 51, with the open side facing the interior of the container 46, which projects outwards over the edge 47 and serves as a projecting locking element. A helical compression spring 52 is arranged in the cup-shaped container 46, which is supported against the bottom 46' of the "cup" and against the projecting edge 49 of the locking element 51. When pressure is applied to the locking pin 51 from the right as shown in Fig. 5, it can be pressed into the container 46 under compression of the helical compression spring 52 up to below the radially beaded edge 47, as shown in Fig. 6, in which the action of the pin-like tool W is shown. In the position shown in Fig. 6, the cover 12 can be moved in its longitudinal direction, i.e. perpendicular to the

Drawing plane can be pushed out of the frame hinge part 10, making the fastening screws 15 accessible.
