Description

Technical area

The invention relates to a fitting with a hinge part, which is adjustable and fixable in two directions when mounted on one of two parts to be joined by a hinge, with a fixation part, which adjustable and fixable a guide piece attached to the hinge part in a first of the two directions and which is to be attached to a first of the two said parts in a second of the two directions adjustable and fixable, and with means for releasably fixing the hinge part with respect to said first part.

State of the art

Shutters serve the weather protection of the window and the darkening of the interiors. They are found in the same way in old (historic) and new buildings. While in the past the shops were mainly made of wood, today they are preferably made of aluminum, because this practically does not age. As aluminum shutters are aesthetically very good solutions, they are also used in the renovation of old buildings instead of wood.

The size of the shutters usually varies from building to building. According to different or individual is the placement of the hinge fittings. When installing the shutter on site, the fittings (mortise ribbons) must be precisely adjusted and fixed, in accordance with the already installed clamp. To facilitate this work, fittings are known which are adjustable and fixable in two mutually perpendicular directions.

From the FR 2.644.505 a fitting is known which comprises an attachable to the wood shutter angle plate, a cruciform guide piece and a loading tape. The angle plate is screwed onto the shutter before the assembly of the loading belt can take place. The guide piece is on the one hand vertically displaceable on the angle plate and on the other hand, the loading tape record horizontally displaceable. With z. B. two screws is the vertical position of the guide piece on the angle plate and with a third screw, the horizontal position of the band is set in the guide piece.

From the FR 2.686.646 Another fitting is known, which can be adjusted in advance for fixing in two mutually perpendicular directions. For fixing a single continuous screw may be provided, which also pierces the store.

The principle of a two-part fitting, in which the two parts are mutually adjustable and lockable, was also in the EP 1 256 681 B1 and the EP 1 382 784 B1 (AST) used. The one fitting part is a substantially square plate, which with its one side (inside) at the shutter can be fixed. For this purpose, two suitably shaped lugs are provided on the inside, which fit into two undercut grooves on the shutter. Further, a recess for the second fitting part is provided on the inside, so that the latter is horizontally displaceable in the first fitting part. With a single pressure screw, on the one hand, the fitting on the shutter and, on the other hand, the position of the two fitting parts can be fixed relative to one another. The pressure screw can be screwed into a thread in the center of the first fitting part and presses on the second fitting part, which is thereby pressed against the shutter. As a result, the first fitting part is pushed away from the shutter. But because he is held by the engaging in the grooves approaches, he braced himself at the shutter and ensures that the hinge fitting is fixed to the shutter. In the EP 1 382 784 B1 For example, the first fitting part is in two parts, with each part having an approach for engaging in the groove. Thus, first the two parts can be inserted into the grooves and then connected to each other.

A hinge fitting, which can be used in ornamental grooves of a shutter, is also also from the EP 1 577 475 A2 known. For convenient insertion of the fitting in the grooves, an opening of the grooves is provided in a portion which has approximately the length of the fitting.

Due to the displaceability and adjustability in two different directions, the known fittings facilitate the preparation of the fixation. The installation of the shutter usually requires two people and a certain training. Furthermore, the logistics and handling is complicated by the fact that the fittings are multi-part.

Presentation of the invention

The object of the invention is to provide a fitting of the technical field mentioned above, which is easy and convenient to install and which has as few unconnected parts.

The solution of the problem is defined by the features of claim 1. According to the invention, the fitting has a hinge part (eg an eyelet for the bolt of a block), which can be adjusted in two directions when mounted on one of two parts to be connected by a hinge (eg on the door leaf or shutter) and is fixable. The fitting further includes a fixation part which receives and fixes a guide piece formed on the hinge part in a first (eg a horizontal direction) of the two directions and which on a first of the two parts (eg on the door leaf or shutter) ) in a second (eg., The vertical direction) of the two directions adjustable and fixable to attach. The means for releasably fixing the hinge part with respect to said first part are characterized in that they comprise two independent and independently operable fixing means, so that the adjustment and fixing in the two directions can be independent and independent.

By the fixation can be done independently in the two adjustment directions, it is possible to perform the adjustment step by step. During assembly, the craftsman can concentrate on the exact adjustment in one of the two directions, which is experience easier than if it must be adjusted simultaneously in two directions. Next, the handling is facilitated because the hinge part z. B. in the vertical direction can be fixed to the shutter so that hanging in the clamp is possible and the shutter can be held with one hand and performed in the correct position, while with the other, the fixation can be done as soon as the position is correct. The shutter can thus be mounted and adjusted by a craftsman alone.

Further, it is possible to prepare the hinge parts for assembly by being fixedly connected to the fixation part (according to previously known dimensions), while adjustability in the second direction still exists. If a larger number of fittings to assemble, in this way the work can be made more efficient, without the fitting needs to be changed.

Preferably, the fixation part has on a side facing the first part (eg the shutter) a recess in which the guide piece can be sunk is. The guide piece can thus be easily inserted into the recess and does not have to be inserted at the end or end. Further, it is advantageous if the guide piece z. B. plate-shaped or strip-shaped and has a slot in which a clamping member of the fixation part can engage, so that the guide piece in the aforementioned first direction adjustable and fixable to the fixation part is clamped. With this construction, the guide piece can be fixed to the fixation part, without at the same time attaching the fixation part to the shutter. Thus, all components of the fitting can be permanently connected to each other. This is an advantage over the fitting, as in the above-described prior art according to EP 1 256 681 (AST).

Instead of a recess which is open on one longitudinal side, it is also possible to provide a closed channel in which the guide piece is to be inserted at the end. The guide piece can then be rod-shaped and square in cross-section or round. It is also not mandatory that the guide piece is sunk in the body of the fixation part. It is also conceivable that the guide on the fixation part is made possible by projecting guide profiles or cams. The fixation of the guide piece on the fixation part in the horizontal direction can also be done without using a slot when z. B. the guide piece is clamped laterally (that is, by pressure on a narrow side).

The slot preferably has a length that is not greater than half the length of the recess. This ensures that the slot is not visible from the outside in any of the possible mounting positions of the guide piece. The length of the recess is usually determined by the width of the fixation part. This is typically shorter than the length of the leader. The need for freely adjustable length of guide piece depends on how different the mounting arrangements are, for which the fitting is to be usable. Also, the dimensions depend on how far away from the edge of the shutter the fixation part is mountable, i. H. where and at which mutual distance the grooves are arranged.

The limitation of the slot length has primarily aesthetic reasons and is by no means mandatory for the invention.

The clamping member is z. B. formed in the manner of a screw, which has a threaded bolt and a bolt head. The bolt head engages in the slot of the guide piece and the threaded bolt can be screwed into a threaded bore of the fixation part. If the threaded bolt is tightened, the bolt head clamps the guide piece to the fixation part. If the threaded bolt solved something, the guide piece with the hinge part is displaced and adjustable, but captive connected.

The slot is preferably formed as a through hole in the plate-shaped guide piece. The edge of the opening is stepped on the side facing away from the fixation part of the guide piece. The step forms a shoulder on which the bolt head can rest. Opposite the main surface of the guide piece surrounding the opening, the gradation is lowered so far that the bolt head has space, so that the bolt head can be sunk in the guide piece. The width of the gradation corresponds at least to the projection of the bolt head relative to the threaded bolt.

The clamping member can also be designed according to the principle of an adjustable wedge. The wedge can z. B. laterally engage the guide piece while exerting, for example, parallel to the second adjustment (ie, for example, vertical) acting clamping force. It is also possible to form the clamping member in the manner of an eccentric, which in rotation to z. B. 90 ° causes the jamming of the guide piece. Although such a clamping member will typically have a bolt (as a rotation axis), but needs no thread on this bolt. The bolt can z. B. immovable in the axial direction, but freely rotatably held in the fixation part.

It is not mandatory that the slot is formed as a continuous opening. He may also have the form of a closed on three sides, undercut groove into which the correspondingly shaped bolt head of the clamping member can engage.

Advantageously, the fixation part in the region of the recess has a continuous threaded bore for the threaded bolt of the clamping member. The threaded bolt may at a remote end of the bolt head have a recessed attack for a tool, so that the clamping member is actuated with mounted fixation part. With a Screwdriver or a hex key, the threaded bolt can be tightened, the guide piece is attached to the fixation part. In conjunction with the preferred embodiments explained above, it can be achieved that the guide piece and the clamping member are accommodated within the convex contours of the fixation part. In particular, there is no screw head which could pose a risk of injury or unsatisfactory aesthetics.

The fixation part is advantageously provided with at least one claw-like projection, which can engage in an undercut groove on the first part (eg at the shutter), such that the fixation part runs along the groove in the second direction (eg in the vertical direction). adjustable and fixable. Basically, a single groove is sufficient for fastening the fixation part. However, if two parallel grooves and multiple lobes are provided, the force can be distributed and the individual contact points can be made finer. The grooves can z. B. be designed so that they appear at first glance as purely aesthetic elements. In this sense, two circumferential grooves may be provided as z. B. from the EP 1 256 681 are known.

Not all approaches need to be formed claw-like. It may also be provided a rib-like, serving as a counter-attack approach, which cooperates with an opposite claw-like approach, so that when fixing the fixation part both approaches are pressed captive against the wall of corresponding grooves. An approach does not need to be a rigidly attached to the fixation part, but may also be adjustable, for. B. in the manner of an eccentric. Depending on the rotational position, such an approach will release the undercut groove or jam in it. Such a trained fixation part can be inserted directly and at any point in the groove and there are no special insertion points (such as EP 1 577 475 known) may be provided.

For easy attachment, at least one dowel pin may be provided on the fixation part, which may come into contact with said first part (eg shutter) and push away the fixation part from the first part and thereby press the claw-like projection in the undercut groove. The dowel pin is through a hole in the Guided fixation part, so that it can be operated from the outside (ie with mounted fixation part).

The clamping pin is preferably designed as a threaded pin with right-handed thread. In contrast, the threaded bolt of the clamping member should have an opposite thread (in this case a left-handed), so that the user can rotate the two independent and independently operable fixative in the same sense to achieve the clamping. Both fixing means have the same thread, the directions of rotation are different for effecting a fixation in the two different Justierrichtungen, so it is advisable to affix a label of the direction of rotation for clamping.

It does not need to be both fixative designed as screws, as the various versions have made clear above.

The fitting is typically rectangular in plan view on its major surface with an aspect ratio close to 1: 1. Almost 1: 1 is understood to mean aspect ratios which do not deviate more than approximately 25% in one direction or the other. With such square close dimensions, a good fixation can be achieved. The claw-like projections are provided in the region of the corners of the square main surface and the recess for the guide piece is designed relatively wide therebetween. The width of the recess should be greater than half the side length, in particular at least 2/3 of the side length.

But it can also be a significantly different form of interest. If the fixation part is elongated rectangular with an aspect ratio of 3: 2 or 2: 1 or larger, the lugs may be in a first (eg lower) half of the fixation part and the recess for receiving the guide piece in a second one (eg. upper half) is provided. The coupling between fixation part and guide piece is then not arranged between the approaches, but next to them. With such a geometry, it is possible to attach the shutter to clamps, which are outside of the intended area of the shutter with the grooves.

The invention is particularly suitable for shutters with a Klobenband. The hinge part is adjustable and fixable during assembly to the shutter in two (preferably perpendicular to each other) directions. The fixation part receives the guide piece formed on the hinge part in a first (horizontal) direction adjustable and fixable and in turn attached to the shutter in a second (vertical) direction adjustable and fixable. The means for releasably fixing the hinge part with respect to the shutter comprise two independent and independently operable fixing means, so that the adjustment and fixing in the two directions can be independent and independent.

If the fitting according to the invention is used for a door or another pivotable wing, the fixation part can also be attached to the stationary part (door frame etc.) instead of the wing.

From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Ways to carry out the invention

Fig. 1 shows the fitting 1 on a support profile 2, which z. B. is part of a shutter, as it looks like Fig. 1 of the EP 1 577 475 A2 (Alurex) is known. The carrier profile 2 is mirror-symmetrical in axis cross-section with respect to the two mutually perpendicular axes I and II, wherein the axis I is parallel to the main surface and is shown with a dashed line and the axis II is perpendicular to the main surface and is shown with dotted line. On the main surface 3.1 two per side undercut grooves 4.1, 4.2 are formed. The undercut is located respectively on that side wall 4.1.1 or 4.2.1, which faces the other groove 4.1, 4.2 ("inner side wall"). In the present example, the undercut is dovetailed, in fact a half dovetail. The second ("outer") side wall of the groove is in each case ramp-shaped in the present example, that is not undercut. The main surface 3.2 is mirror-symmetrical to the main surface 3.1 provided with grooves.

The fitting 1 consists essentially of two parts, namely a hinge part 5 and a fixation part 6. The hinge part 5 has a strip-shaped guide piece 7, at its outer end a tubular eyelet 8 is formed for the (not shown) hinge pin of a clamp. The fixation part 6 is so large that it can engage with opposing claw-like projections 9.1, 9.2 in the two grooves 4.1, 4.2. He preferably has three screws, namely a lag screw 10 and two pressure screws 11.1, 11.2.

Out Fig. 2a it can be seen that the fixation part 6 is approximately square in plan view. The strip-shaped guide piece 7 extends in Fig. 2a into the fixation part 6 and passes through it from one side 12.1 almost to the other side 12.3. It protrudes in the position shown about one third out of the fixation part 7 out. The pressure screws 11.1, 11.2 are arranged in the diametrically opposite corner regions and indeed within a range which is bounded by the projections 9.1, 9.2, but outside a region which passes through the recess 13 is taken. The lag screw 10 is placed in the center of the square fixation part 7, ie in the area which lies within the recess 13.

As based on the Fig. 2b it can be seen, the lag screw 10 and the pressure screws 11.1, 11.2 have two different functions. The lag screw 10 is part of a (first) fixing means for adjustable and lockable connection of guide piece 7 and fixation part 6. The pressure screws 11.1, 11.2 in turn are part of a (second) fixing means for adjustable and lockable connection of fixation part 6 and support profile 2 (z a shutter).

The guide piece 7 has an elongate passage opening 14 (slot) for the pin 20 (FIG. Fig. 2c ) of the lag screw 10. The passage opening 14 extends z. B. on the longitudinal central axis of the guide piece 7 and is about half as long as the fixation part 6 is wide. (The width of the fixation part 6 is defined by the distance of the two parallel to the grooves 4.1, 4.2 extending sides 12.1, 12.3.) On the back 15 of the guide piece 7 (ie on the side of the guide piece 7, which faces the support section 2 ( see. Fig. 2c ), the passage opening 14 is surrounded by a gradation 17. The step 17 has a depth which corresponds at least to the thickness of the head 21 of the tension screw 10, so that the head 21 does not protrude beyond the back 15 of the guide piece 7 addition. The width of the step 17 corresponds at least to the size of the projection of the head 21 relative to the pin 20.

The recess 13 extends from the side 12.1 to the side 12.3 of the fixation part 6. It is so wide that the guide piece 7 receives a good linear guide. The depth of the recess 13 is slightly larger than the thickness of the guide piece 7, so that the guide piece 7 is freely displaceable with the lag screw released between the fixation part 6 and the carrier profile 2 (horizontal), regardless of whether the fixation part 6 on the carrier profile 2 (FIG. vertically) is slidably held or fixed.

Out Fig. 2b is further seen that the pressure screws 11.1, 11.2 in an edge region of the fixation part (between the region of the recess 13 and the side 12.2 or 12.4 of the fixation part 6) are guided therethrough. It can also be seen that the pressure screws 11.1, 11.2 extend horizontally between the Approaches 9.1, 9.2 are arranged. They thus press on the main surface 3.1 of the carrier profile 2 and press the fixation part 6 away from the main surface 3.1.

Fig. 2c shows the section AA according to Fig. 2b , The approaches 9.1, ..., 9.4 (of which in the Fig. 2c the two lugs 9.1, 9.2 are visible) protrude beyond the flat lower side of the fixation part 6 and over the back side 15 of the guide piece 7 inserted into the recess 13. There are the pin 20 with the underlying head 21 can be seen. The upper end of the pin 20 has a recess 22 as a countersunk attack (e.g., hex) for a tool. On the front side 16, the surface may be provided with a toothing, so that when tightening the lag screw 10 (pin 20) is given a good fixation of the guide member 7 on the fixation part 6. Finally is off Fig. 2c It can also be seen that the upper side of the fixation part is beveled laterally and consequently thicker in the middle (in the area of the lag screw 10) than in the area of the extensions 9.1, 9.2.

Fig. 3 shows a further embodiment of the invention. It is particularly advantageous when the clamp is mounted near the corner of the shutter, in an area in which the grooves are no longer available.

The corner profile 32 is fragmentary and shown only schematically. There are the grooves 34.1, 34.2 located in which the lugs 39.1, 39.2 (shown here as dotted lines, which engage behind the grooves) intervene. The lugs 39.1, 39.2 extend over a certain length of the fixation part 36. They end z. B. in a certain distance from the recess 43. In the area in which the lugs 39.1, 39.2 are formed, neither a lag screw nor a recess for the guide piece 37 is formed. Rather, here are only the two pressure screws 41.1, 41.2. They are arranged in a sense diagonally to each other. However, it is also possible to provide two pressure screws placed on the same horizontal line, or four pressure screws placed in the corners of an imaginary rectangle.

The recess 43 is formed in the lower part of the fixation part 36, that is separated from the upper area with the pressure screws 41.1, 41.2. As a result, the in Fig. 3 shown fixation part in the direction of the grooves 34.1, 34.2 longer than transverse to it.

The guide part with the eyelet can be formed in principle the same as in the fitting. 1

The described embodiments can be modified in many ways. It can z. B. four pressure screws are provided so as to allow the fixation reliable. The lag screw does not need to be arranged in the center of the fixation part, for example, it can also be closer to the side 12.1. The guide piece 7 may be formed by two mutually spaced rods, instead of a plate. The lag screw can then be replaced, for example, by an eccentric which engages between the two rods and presses them outward against the edge of the recess 13.

The recess 13 does not need to be continuous from the side 12.1 to page 12.3. It can already end before page 12.3.

Not all approaches need to be claw-like. In the illustration according to Fig. 2c could approach 9.2 z. B. also be designed as a straight rib, which is pressed against a likewise straight side wall of the groove. The (horizontal) clamping force can, for. B. when clamping the pressure screw 11.1 in conjunction with the inclined surface on the approach 9.1 are generated in the associated groove. The pressure screw 11.2 is preferably provided in this variant in the approach 9.3 instead of approach 9.4.

Instead of providing a passage opening 14 in the guide piece 7, a vertically protruding pin with thread can be provided on the front side 16. For this pin, a slot can be provided in the fixation part, through which the pin can protrude. On the outside of the fixation part (i.e., the side facing away from the support profile), a nut can be screwed onto the post so that the guide piece is pulled against the fixation part. So that the nut and the pressure screws are not visible, a cover can be put over the fitting.

The guide piece may also be formed without the gradation, if it is thinner than the depth of the recess 13. For stabilization and lateral ribs may be provided.

The head 21 of the bolt may be elliptical or otherwise out of round rather than round. In the long diameter axis, this elliptical head has a dimension that can span across the slot longitudinal direction in the slot 14, and in the short diameter axis, the dimension is smaller than the width of the slot 14 with sufficient clearance. By a rotation of the bolt to z. B. 90 ° so the guide piece 7 with the fixation part 6 are firmly connected.

It is also possible, instead of a rigid approach to provide a rotatable eccentric-like approach, which engage in the undercut groove and can clamp there.

The inventive principle can also be used for mounting another hinge part, for. B. used for a clamp.

In summary, it should be noted that the assembly of the fittings can be considerably facilitated and simplified by the invention.
