A flat clamp plate (3) is at the under side (22), secured by an adjustable fastener screw (4). The clamp and the fastener together can tilt in relation to the body on an axis (17) parallel to the groove.

Description

The present invention relates to a closing part designed for fastening in an elongate receiving groove of a glazing or sash of a window, a door or the like with a closing part base body, on the upper side at least one holding portion for a locking element of the window, the door or the like is provided.

Locking parts of the type mentioned are used in particular in aluminum frames of windows, doors or the like. The aluminum profiles of these frames usually have a circumferential receiving groove in which the closing parts or other fitting elements can be attached. The receiving groove is provided on both its longitudinal sides with inwardly projecting edge edges, so that the closing part can be inserted from above into the receiving groove and inserted with a holding portion under one of the peripheral edges of the receiving groove. For fastening the opposite side of the closing part, a diagonally extending threaded bore is usually formed in the closing part, into which a grub screw is screwed. The bore is guided so that the entrance of the bore at the top of the closing part and the output are arranged on the opposite side of the holding portion of the closing part. The screwed from above into the closing part grub screw can be screwed so far after insertion of the closing part in the receiving groove that the front end of the grub screw exits the outlet of the bore and protrudes below the second edge of the receiving groove. In a further screwing the grub screw whose free end occurs with an inner wall or with the bottom of the receiving groove in connection, whereby the closing part is clamped in the receiving groove.

The problem with this attachment, however, is that the screwed-in grub screw, the coated surface of the aluminum profile is damaged, which can lead to corrosion in the screw and the closing parts, since the screws are usually designed as steel screws and the closing parts as Zinkdruckgussteile. In addition, the different components have different coefficients of thermal expansion due to the different materials, so that with appropriate heat or cold by tension differences loosening of the closing part is possible.

It is an object of the present invention to design a closure part of the type mentioned at the beginning in such a way that reliable fastening of the closure part within the receiving groove is possible without the risk of corrosion or loosening of the closure part.

Starting from a closing part of the type mentioned above, this object is achieved in that on the underside of the closing part body a flat clamping element is arranged, which is connected to the closing part base body via an adjustable fastening element, wherein the clamping element and the fastening element are tilted relative to the closing body part ,

By tilting the clamping member relative to the closing part of the main body, it is possible to introduce the clamping element initially with a clamping edge obliquely from above into the receiving groove, that this clamping edge comes to rest under one of the marginal edges of the receiving groove.

During the subsequent complete insertion of the clamping element into the receiving groove, the clamping element, together with the fastening element, in turn tilted relative to the closing-part basic body, but this time counter to the previous tilting movement, until the clamping element and closing-part basic body are again aligned parallel to one another. In this state, the clamping element can be moved via the fastening element in the direction of the closing part base body that the marginal edges of the receiving groove between the clamping element and the closing part base body are clamped and the closing part is securely fixed in the receiving groove. Since only surface elements of the closing part and of the clamping element come into contact with the surface of the metal profile for this clamping attachment, there is no risk that its coated surface will be damaged, so that a risk of corrosion can be ruled out. A loosening of the closing part is practically excluded in this clamp attachment.

According to an advantageous embodiment of the invention, the fastening element is designed as a screw. As a result, a simple configuration is achieved and it is a very fine and easy adjustment of the clamping element possible.

According to a further preferred embodiment of the invention, the clamping element is designed as a clamping plate. In principle, it is also possible that the clamping element is not designed as a clamping plate, but for example as a clamping frame or other flat component. It is only essential that the clamping element is formed so flat that it can be accommodated in the receiving groove and thereby has flat portions which can engage behind the inwardly projecting marginal edges of the receiving groove and surface of these come to rest.

According to a further advantageous embodiment of the invention, the fastening element and the clamping element are tiltable about an axis extending substantially parallel to the longitudinal axis of the receiving groove. A corresponding axis may for example be formed on the clamping element, wherein the formation of corresponding stub axle is sufficient. However, the axis may also be only a virtual axis about which the fastener and the clamping element can be tilted.

According to a further preferred embodiment, in the case of a tilted clamping element, an edge of the clamping element extending parallel to the longitudinal extension of the closing part main body and designed as a clamping edge has a greater distance from the underside of the closing part main body than an edge of the clamping element opposite the clamping edge. By this greater distance a simple insertion of the clamping element with its clamping edge in the receiving groove is possible.

According to a further advantageous embodiment of the invention, the closing part base body has an opening through which the fastening element is passed, wherein the fastening element in the opening is both longitudinally displaceable and tiltable. In particular, the opening is flared toward the underside of the closing part base body, whereby the tilting of the fastening element and the associated clamping element is made possible.

According to a further preferred embodiment of the invention, the clamping element is designed to be movable perpendicular to the longitudinal axis of the closing part main body. This movement of the clamping element perpendicular to the longitudinal axis of the closing part base body is thus in addition to the tilting possible, which ultimately achieves that the clamping edge of the clamping element can be pushed under a first peripheral edge of the receiving groove and the clamping edge of the opposing portion of the Schließteilgrundkörpers under the opposite edge of the receiving groove.

According to a further advantageous embodiment of the invention, the clamping element is designed to be immovable parallel to the longitudinal axis of the closing body part. Likewise, the clamping element is designed to be non-rotatable about a longitudinal axis of the fastening element. This ensures that the clamping element automatically has a correct positioning relative to the closing part main body, which ultimately leads to the fact that the closing part is automatically positioned correctly after insertion into the receiving groove.

According to a further preferred embodiment of the invention, the clamping element is movable by the fastening element in the direction of the closing part main body. This movement takes place in particular by screwing the fastening element into the clamping element, as a result of which it is pulled in the direction of the closing-part main body.

According to a further advantageous embodiment of the invention, the clamping element has a smaller width than the closing part main body. The width here is defined as the dimension perpendicular to the longitudinal extent of the closing part, wherein the longitudinal extent of the closing part extends in the longitudinal direction of the receiving groove when the closing part is attached.

According to a further preferred embodiment of the invention is a parallel to the longitudinal extent of the closing part body running Edge of the clamping element formed as a clamping edge, which engages behind a receiving edge upwardly bounding the first peripheral edge with the closing part attached. At its side opposite the clamping edge, the closing body part preferably comprises a receiving section, which is designed to receive a second peripheral edge of the receiving groove opposite the first peripheral edge. Thus, each of the two marginal edges of the receiving groove is engaged in each case by the clamping element and the closing part of the main body, so that after screwing the clamping member with the closing part body, the closing part can not be pulled upwards out of the receiving groove.

Preferably, the closing part base body comprises on its underside two support portions, which bear against the marginal edges of the receiving groove when the closing part is fastened. As a result, a clamping region is formed when the closing part is fastened between the clamping edge of the clamping element and one of the support sections of the closing part base body, in which the first peripheral edge of the receiving groove can be clamped, whereby a stable fastening of the closing part takes place in the receiving groove.

Further advantageous embodiments of the invention are specified in the subclaims.

Fig. 1 shows a closing part 1, which includes a closing part main body 2, a clamping element 3 and a fastener formed as a screw 4. While the screw 4 is usually designed as a steel screw, the closing part main body 2 and the clamping element 3 are formed, for example, as zinc die-cast parts. In principle, both the screw 4 and the clamping element 3 and the closing part main body 2 can be made of other suitable materials.

The closing part main body 2 has on its upper side 5 two recesses 6, which together with a T-shaped web 7 holding sections 8 for a locking element of a window, a door or the like form.

In the central region of the web 7, an opening 9 is formed, through which the screw 4 can be guided. The screw 4 has a countersunk head screw head 10, which is received in the opening 9 by a trained in the upper region of the opening 9, funnel-shaped portion 11 upon complete insertion of the screw.

The clamping element 3 has in its central region a threaded projection 12 into which the screw 4 can be screwed after passing through the opening 9, so that the closing part main body 2 and the clamping element 3 are connected to each other via the screw 4. In principle, the thread for the screw 4 can also be formed directly in the clamping element 3 without protruding projection 12.

The clamping element 3 comprises a rectangular main part 45 and forms an elongated clamping plate which is aligned along a longitudinal axis 13 of the closing part main body 2. A first longitudinal edge 14 of the clamping element 3 is designed as a clamping edge and has a step-shaped design with a closing part of the base body 2 facing bearing surface 15 and the contact surface 15 opposite inclined surface 16th

At the clamping edge 14 opposite longitudinal side 47 of the clamping element 3, a pivot axis 17 is formed, which may be formed, for example, on the clamping element 3. Basically, the pivot axis 17 may also be formed as a separate part. The pivot axis 17 has two free ends 18, 19 which protrude laterally beyond the rectangular main part 45 of the clamping element 3 and, when the closing part 1 is assembled, respectively protrude into a receiving section 20, 21 of retaining lugs 23, 24 arranged on the underside 22 of the closing element main body 2.

Each receiving portion 20, 21 has an inner portion 25, 26 and an associated with this, outer portion 27, 28. The inner portions 25, 26 are along the bottom 22 of the closing part base body 2 in a direction perpendicular to the longitudinal axis 13 formed deeper than the outer sections 27, 28 and take in composite closure part 1, the free ends 18, 19 of the pivot axis 17. Due to the great depth of the inner portions 25, 26, the pivot axis 17 can move in the assembled state of the closing part 1 in the inner portions 25, 26 perpendicular to the longitudinal axis 13 along the bottom 22 of the closing part main body 2, so that a corresponding displacement of the Clamping elements 3 is possible. At the same time pivoting of the clamping element 3 about the longitudinally displaceable pivot axis 17 is possible.

The distance between the two retaining lugs 23, 24 is only slightly larger than the longitudinal extent of the rectangular main part 45 of the clamping element 3, so that when assembled closure part 1, the rectangular main part 45 of the clamping element 3 is arranged between the two holding lugs 23, 24 that only the described pivoting or displacement of the clamping element 3, but not a rotation, for example, about a longitudinal axis 29 of the screw 4 or tilting about an axis perpendicular to the pivot axis 17 extending axis is possible.

In addition, further projections 30, 31 are formed on the underside 22 of the closing part main body 2, the distance between them is also slightly larger than the longitudinal extent of the rectangular main part 45 of the clamping element 3. Thus, a displacement of the clamping element 3 in the direction of the longitudinal axis 13 or a rotation the clamping member 3 about the longitudinal axis 29 through these lugs 30, 31 also prevented.

The outer portions 27, 28 of the receiving portions 20, 21 have not only a smaller depth than the inner portions 25, 26, but also a lower height, this height from the rear open end of the outer portions 27, 28 to the reduces front closed end, since the outer portions 27, 28 each bounded below by an inclined boundary surface 32, 33. At the same time, the boundary surfaces 32, 33 form the upper side of wedge-shaped holding sections 39, 40 of the closing part main body 2.

Based on Fig. 2 to 6 The attachment of the closing part 1 will be described in detail below.

In Fig. 2 is a part of a frame 34 indicated indicated, which may be formed, for example, as an aluminum profile. In the frame 34, a circumferential receiving groove 35 is formed, whose upwardly open side is bounded by a first peripheral edge 36 and a second peripheral edge 37.

To insert the preassembled closing part 1, this is inserted into the receiving groove 35 in accordance with an arrow 48 such that initially only the clamping edge 14 of the clamping element 3 comes to lie below the first peripheral edge 36, as shown in FIG Fig. 3 is shown.

To the clamping element 3 together with the screw 4 relative to the closing part main body 2 as in Fig. 3 shown, the opening 9 in the direction of the bottom 22 of the closing part body 2 has a widening portion 38 and an adjoining cavity 46 for receiving the neck 12, by the tilting of the screw 4 and thus also the clamping member 3 opposite the closing part main body 2 is made possible. The clamping element 3 thereby tilts about the pivot axis 17, the in Fig. 3 opposite to their position in Fig. 2 is displaced in the inner portion 25 of the receiving portion 20 to the rear open end.

According to Fig. 4 In a next step, the closing part base body 2 is tilted so that the longitudinal side 47 of the clamping element 3 lying opposite the clamping edge 14 is also moved into the receiving groove 35 with the pivot axis 17.

Both in the post position Fig. 3 as well as after Fig. 4 In this case, the retaining lugs 30, 31 each at the top of the first peripheral edge 36 at.

In the step according to Fig. 5 the closing element main body 2 is displaced to the right so far that the projections 30, 31 extend beyond the first peripheral edge 36 and into the receiving groove 35. At the same time, the holding section 39, 40 of the holding lugs 23, 24 enters the region of the receiving groove 35 below the second peripheral edge 37, so that the second peripheral edge 37 comes to rest in the outer sections 27, 28 of the holding lugs 23, 24 it out Fig. 5 can be seen. Should the clamping element 3 also be displaced to the right due to frictional forces, this movement is limited by the second peripheral edge 37. The pivot axis 17 runs at a right shift of the clamping element 3 against the second peripheral edge 37, so that a further rightward displacement of the clamping element 3 is prevented, which could result in that the clamping edge 14 would be moved away from its first edge 36 behind engaging position. In addition, the in Fig. 5 shown positioning of the clamping element 3 also in that the screw 4 by a between the funnel-shaped portion 11 and the flared portion 38 of Breakthrough 9 lying bottleneck 41 in their in Fig. 5 shown position is pressed and fixed there, so that the clamping element 3 automatically in the in Fig. 5 shown position is brought.

In the in Fig. 6 shown last step, the screw 4 is further screwed, whereby the clamping element 3 is pulled in the direction of the closing part base body 2 upwards, until ultimately the clamping edge 14 comes to rest with the contact surface 15 at the bottom of the first peripheral edge 36. In this position, the peripheral edge 36 is thus clamped between the contact surface 15 of the clamping edge 14 and an opposite, formed on the underside 22 of the closing part 2 base support portion 42. Between the support portion 42 and the clamping edge 14, a clamping region 44 for the peripheral edge 36 of the receiving groove 35 is thus formed.

Similarly, the second marginal edge 37 is clamped between a support portion 43 formed on the underside 22 of the closing body portion 2 and the inclined lower boundary surface 32, 33 of the outer portion 27, 28 of the receiving portion 20, 21, so that a secure attachment of the closure member 1 is ensured in the receiving groove 35. Here are closing part 1 and frame 34 only via flat contact points with each other, so that the risk of injury to the coating of the frame 34 and thus a risk of corrosion is prevented. Since the flat contact points for fastening the closing part in each case only pressed against each other, but not slid against each other sliding against each other, also occur no grinding marks, which in turn could cause corrosion. A loosening of the attachment is excluded due to the clamp mounting according to the invention.

That in the Fig. 7 to 12 embodiment shown corresponds essentially to the embodiment according to the Fig. 1 to 6 , In contrast to the previously described closing part 1 is in the closing part 1 'after the Fig. 7 to 12 the clamping element 3 'only connected via the screw 4 with the closing part main body 2, but not via a pivot axis 17, which is omitted in this second embodiment. The pivoting movement of the clamping element 3 'is thus limited in this embodiment, only by the pivoting of the screw 4, as in particular the Fig. 9 and 10 can be seen.

Since no pivot axis 17 is present, there are no inner sections 25, 26 and outer sections 27, 28, but the holding sections 20 ', 21' each extend over the entire width of the holding lugs 23 ', 24'. At the same time are in the in the Fig. 7 to 12 shown embodiment, the retaining lug 23 'and the lug 30' and the retaining lug 24 'and the lug 31' each formed integrally with each other. Basically, however, these approaches could also, as in the embodiment of the Fig. 1 to 6 be formed separately from each other. Conversely, in the embodiment according to the Fig. 1 to 6 each of the retaining lug 23 and the projection 30 and the retaining lug 24 and the projection 31 are integrally formed with each other, as is the case in the second embodiment.

As in particular from the 8 to 12 can be seen, in the second embodiment, the funnel-shaped portion 11 'is made wider on one side, so that the opening 9 on the upper side 5 of the closing part base body 2 has a slot shape. How out Fig. 9 can be seen, thereby a greater pivotability of the screw 4 is achieved, so that the insertion of the clamping edge 14 below the first peripheral edge 36 is facilitated. This embodiment of the funnel-shaped portion 11 'can also be provided in the first embodiment.
