Fixtures for fastening elements to windows, doors or similar structures

technical field

The invention relates to a fastening device for fastening a component to a recess, in particular an undercut, of a window, door or similar structure, said fastening device having a clamping element into which a bolt passing through the component is screwed element.

Background technique

For fastening components, in particular fittings, to profiles with undercut grooves, such as window or door frames, it is known to use slides, which are introduced into the groove and then rotated, The slider thus acts from behind on the undercut undercut (also called slot stop or slot stop).

A swing hinge is known from DE 20113607 U1, which is fastened to the profile via slot nuts. Bolts are screwed into the slider. As a result, the slide is moved in the direction of the component to be fastened, so that the slot stop is clamped between the slide and the component.

However, it cannot be completely avoided in this fastening method that the component is displaced in the longitudinal direction of the groove under the action of a corresponding force.

Contents of the invention

It is therefore the object of the present invention to provide a fastening device by means of which a displacement of the component to be fastened in the longitudinal direction of the groove can be effectively prevented.

This task is solved by a fastening device for fastening a component to an in particular undercut groove of a window, door or similar structure, said fastening device having a clamping element into which a bolt passing through the component is screwed. In the above clamping element, wherein the bolt has a form-locking end and/or a force-locking end for forming a form-locking and/or force-locking with the groove. In this case, the screw is dimensioned in such a way that after the screw has been screwed into the clamping element, its free end comes into contact with the groove bottom of the groove. Through the direct interaction of the fastening screw with the groove, in addition to the clamping by the clamping element, the fixing of the component on the groove or on the profile can be achieved, so that the component is additionally fixed in its position by the screw. Here, the screw is preferably dimensioned in such a way that it is ensured that the screw practically also contacts the bottom of the groove with its tip after screwing in.

According to a preferred embodiment of the invention it can be provided that the screw is designed as a punched screw. As a result, the free end of the screw is configured such that it can be driven into the bottom of the groove. If the profile to which the component is to be fastened is an aluminum profile, when the punching bolt is screwed in, the free end of the punching bolt can be inserted into the wall of the profile forming the bottom of the groove and if necessary passed through said wall . This results in a positive connection between the punching bolt and the profile, so that a displacement of the component in the longitudinal direction of the profile or of the groove is effectively prevented.

According to an alternative embodiment, the screw can be designed as a clamping screw. In this case, the screw can be screwed in so far that the free end presses against the groove bottom and thus forms a non-positive connection. Displacement in the longitudinal direction is thereby also effectively prevented. In this case damage is prevented, in particular punch holes in the groove are prevented. However, the clamping bolt can be screwed in until a slight plastic deformation of the groove bottom occurs.

Furthermore, it is conceivable for the screw to have a punching section and a clamping section at its end. A particularly secure fastening of the component can be achieved with such a design of the screw. The bolt engages here with a punched section into the groove bottom, while the clamping section additionally achieves a non-positive connection. To this end, the free end of the bolt can be configured in a stepped manner, wherein a first section can be provided with a smaller diameter, which section serves as a punch section, and a second section connected to the first section can It is designed with a larger diameter so that the second section can bear against the groove bottom and achieve a clamping connection.

According to a particularly preferred embodiment of the invention, it can be provided that a rotational lock is formed between the clamping element and the screw. This means that the rotation between the clamping element and the screw is locked, or that the screw is initially connected to the clamping element in a rotationally fixed manner. This ensures that, when the screw is rotated, the clamping element initially moves with the screw. Only when the clamping element is in contact with the groove wall and cannot be rotated any further can a sufficient torque be applied to rotate the bolt relative to the clamping element. This now pulls the clamping element towards the undercut of the groove. A non-rotatable or rotationally locked arrangement of the screw on the clamping element can be achieved by using a screw reinforcement paint, by pressing the thread of the clamping element or of the screw, or by using a Undersized threads. Other possibilities are also conceivable for fastening the bolt to the clamping element in a rotationally fixed or rotationally locked manner. A particular advantage of this fastening device is the ease of assembly. Whereas conventionally only certain torques were permitted when fastening the clamping elements in order to avoid damage, the fastening device according to the invention can be mounted with an electric screwdriver. It doesn't matter how far the set bolt is driven into the bottom of the slot.

The clamping element can have a clamping section, wherein in the clamping position a groove bridge or an undercut is clamped between the clamping section and the component. According to one specific embodiment, it can also be provided that the clamping element has two clamping sections, which in the clamping position interact with a slot bridge each, or between the clamping section and the A slot bridge is clamped between the components.

The clamping element can be configured as an eccentric. In particular, the end of the clamping section can be farther from the pivot point of the clamping element than the opposite end of the clamping element.

According to one embodiment of the invention it can be provided that the clamping element is chamfered at least on one edge section. Within the scope of the present invention, an edge section with a slight curvature is also to be understood as a chamfered edge section. This chamfer of the clamping element facilitates insertion of the clamping element into the groove.

According to a particularly preferred embodiment, a clamping piece can be provided which is entrained by the clamping element when the clamping element is displaced in the direction of the component. As a result, the clamping element can initially be displaced into the clamping position by the rotational movement of the screw. Further rotation of the screw thus displaces the clamping element in the direction of the component, if the clamping element abuts against the groove wall in the clamped position and is therefore unable to rotate any further. The clamping piece is preferably arranged in one section between the clamping element and the component, so that when the clamping element is displaced in the direction of the component, the clamping piece is also displaced in the direction of the component and thereby clamps the undercut of the groove.

It can also be provided that the clamping piece is displaceable transversely to the axis of the screw during the rotational movement of the clamping element. As a result, the clamping piece can be moved under the undercut of the groove. The displacement of the clamping element into the clamping position thus also enables the displacement of the clamping block into the clamping position. For this purpose, the clamping piece preferably has a control curve along which the clamping element is moved when the clamping element is rotated in order thereby to achieve a displacement of the clamping piece relative to the screw axis. This has the advantage that the fastening device does not have to be pivoted into the groove.

The clamping block advantageously has a clamping element recess for receiving the clamping element. The clamping element recess can form a control curve. Furthermore, a section of the clamping piece can thus be arranged between the clamping element and the component while achieving a space-saving construction.

It is particularly advantageous if an inversion safety device is provided on the clamping block for preventing the clamping element from tipping over. In particular, the clamping block can have a recess, which is adapted to the shape of the clamping element, so that in the clamping position the clamping element lies in the recess and cannot easily be turned back. In particular, in its clamping position, the clamping element can “slide” into the recess and rest with its straight side on a straight section of the wall of the recess.

Reliable holding of the component on the profile can be achieved if the clamping block, which has a plurality of clamping element recesses for a plurality of clamping elements, is designed as a clamping strip.

Assembly is further facilitated if the clamping piece is chamfered at least in one edge section. The clamping piece can thus be inserted into the groove more easily. In particular, the fastening device can be guided into the groove by a pivoting movement about the longitudinal axis of the fastening device. The chamfer can be rounded.

Furthermore, windows, doors or similar structures having a fixing device according to the invention also fall within the scope of the invention.

Further features and advantages of the invention emerge from the following description of an exemplary embodiment of the invention with the aid of the drawing showing important details of the invention and from the claims. Each feature can be described independently, or can be described in multiples in any combination in the solution of the present invention.

Description of drawings

A preferred exemplary embodiment of the invention is shown schematically in the drawing and will be described in more detail below with reference to the drawing. The figure shows:

FIG. 1 shows a view from below of a fastening device with two clamping elements in assembled position;

Figure 2 shows a view from below of the fixing device with the clamping element screwed into the clamping position;

Figure 3 shows a sectional view of a frame profile to which the components are fastened by means of fastening devices;

4a to 4d are used to describe enlarged views of the clamping fastening, wherein the individual details correspond to the sections marked with X in FIG. 3 .

Detailed ways

1 shows a view from below of a fastening device 1 for fastening a component 2 designed as a corner bearing to a window, door or similar structure, in particular to a fitting channel of a frame profile . The fastening device 1 has two clamping elements 3 , 4 which are held on the component 2 via screws 5 , 6 . In the assembly position shown, the screws 5 , 6 are partially screwed into the clamping elements 3 , 4 . It can be seen that the clamping elements 3 , 4 , which are rotatable about the screw axes of the screws 5 , 6 , are designed eccentrically. The clamping elements 3 , 4 each have a clamping section 7 , 8 .

The fastening device 1 also has a clamping piece 9 configured as a clamping strip. The clamping block 9 has two clamping element recesses 10 , 11 in which the clamping elements 3 , 4 are arranged.

In the illustration of FIG. 2 , which essentially corresponds to the illustration of FIG. 1 , the clamping element 3 has been rotated by 90° and is now in the clamping position (in the clamping position, the clamping element with its clamping section 7 rests against against the tank wall not shown). By rotating through 90°, the section 12 of the clamping element 3 moves in the clamping element recess 10 . In the position shown, the clamping element 3 is located in the recess of the clamping element recess 10 , whereby a tilting of the clamping element 3 is prevented. In the position shown, both the clamping piece 9 and the clamping element 3 can engage a corresponding undercut of the fitting groove from behind.

The edges of the clamping element recesses 10 can be used as control curves 13 . If the clamping element 3 is not configured eccentrically, as shown in the figures, but symmetrically with respect to its axis of rotation, a displacement of the clamping piece 9 transverse to the axis of the screw 5 occurs when the clamping element 3 rotates.

It can also be seen in FIG. 2 that the free end of the screw 5 has a pierced section 14 and a clamping section 15 . In the position shown, the clamping element 3 cannot be further rotated. If the screw 5 is rotated further against this, it is screwed further into the clamping element 3 , so that the free end moves in the direction of the groove bottom of the fitting groove. The punched-out section 14 can then enter into the groove bottom. The clamping section 15 can be supported on the groove bottom. A longitudinal displacement of the component 2 in the longitudinal direction of the component 2 or along the fitting groove is thus effectively prevented.

The screw 6 has only one clamping section at its free end and can thus produce a non-positive fit with the groove bottom.

FIG. 3 shows a frame profile 20 which has an undercut groove 21 (fitting groove), which is also called a C-shaped groove. The groove 21 has undercuts 22 , 23 , which are also called groove stops or groove stops. It can be seen that the component 2 is placed above the undercuts 22 , 23 , while the clamping piece 9 is arranged in the groove 21 and below the undercut 22 with the clamping section 24 . In the region of the clamping section 24 the clamping piece 9 is chamfered, so that the clamping piece 9 can be easily arranged in the groove 21 . In particular the component 2 can thus be easily swiveled into the groove 21 together with the clamping piece 9 .

In the enlarged detail view of FIG. 4 a corresponding to section X of FIG. 3 , it can also be seen that the clamping section 24 has a small distance from the undercut 22 , while the second undercut 23 has not yet been covered from behind. catch. Furthermore, it can be seen that the screw head 25 of the screw 5 protrudes beyond the component 2 . The screw 5 is thus only partially screwed into the clamping element 3 .

The screw 5 is connected in a rotationally locked manner to the clamping element 3 . As a result, when the screw 5 is turned, initially no relative movement between the screw 5 and the clamping element 3 occurs, but the clamping element 3 is entrained by the screw 5 . This situation is shown in Figure 4b. It can be seen that the clamping section 7 of the clamping element 3 is only at a certain distance below the undercut 23 . The clamping block 9 is not displaced in its position compared to FIG. 4a. The distance of the bolt head 25 from the component 2 also does not change.

Further rotation of the bolt 5 results in the rotational locking between the bolt 5 and the clamping element 3 being overcome. The screw 5 is thus screwed into the clamping element 3 , which has the result that the clamping element is displaced upwards, as shown in FIG. 4 c . The clamping piece 9 is also moved by the clamping element 3 , so that both the clamping piece 9 and the clamping element 3 now bear with their clamping sections against the undercuts 22 , 23 , respectively. It can also be seen in FIG. 4 c that the pierced section 14 now protrudes downwards beyond the clamping piece 9 and contacts the groove bottom 26 .

When the screw 5 is rotated further, the piercing section 14 plunges into the groove bottom 26 , so that the clamping section 15 comes into contact with the groove bottom 26 . The screw head 25 is now no longer visible because the screw head is inside the component 2 . A positive and non-positive fit with the groove 21 is thus achieved by the free end of the screw 5 . This is shown in Figure 4d.
