Description

Band arrangement for doors, windows or the like

The invention relates to a hinge assembly for doors, windows or the like with a hinge part, which comprises a hinge part and a fastening part, wherein the fastening part is mounted on a mounting surface of a frame or a wing, with an attachable to the mounting surface Führungsele- element, which in a Guide recess in the fastening part leader engages, so that the fastening part is displaceable perpendicular to the mounting surface, and with a displacement effecting displacement element.

Such a band arrangement is known, for example, from DE 101 52 366 C5. It comprises a receiving piece which can be fixed in a hollow profile. In the receiving piece guide bores are provided, which continue in perforations in a mounting side forming the profile wall. On the fastening part of the hinge part support pins are provided, which are designed to be inserted into the guide holes and optionally spreadable, so that the determination of the hinge part can be done in the desired position by jamming the support pins in the guide holes.

The adjustment of the wing in the frame for the purpose of adjustment is a threaded element, which is fixed to the fastening part in the adjustment and an external thread, which is screwed into a complementary, provided in the receiving piece internal thread.

A disadvantage of this band arrangement is that it is expensive to produce because of the large number of different components.

Another, the features mentioned above having band assembly is known from DE 20 2005 012 152 U1. It comprises two guide elements which project from the mounting wall and are spaced apart from one another with cylindrical lateral surfaces. They engage in guide holes, which are incorporated in the fastening part. As a displacement element is a threaded spindle having a radial extension. The thread of the spindle is in engagement with a complementary thread on the frame or the wing and the radial projection with a receptacle on the fastening part, or the threaded extension with a complementary thread on the fastening part and the radial projection with a receptacle on the frame or the wing ,

In this, particularly inexpensive to produce band assembly is an adjustment perpendicular to the mounting surface - in the case of doors also called "horizontal adjustment" - in a particularly simple manner by only the displacement element is rotationally actuated, whereby the fastening part and all associated with this band parts in the longitudinal direction Although this band arrangement provides a practically desirable, particularly simple and inexpensive horizontal adjustment possibility, it has been shown in practice that, in particular under high loads, for example due to high sash weights during displacement, it is possible to clamp the guide Mounting part can come on the guide elements.

The invention has for its object to provide an improved, generic band assembly. This object is achieved by the reproduced in claim 1 band assembly.

In the band assembly according to the invention, the displacement element is both in positive engagement with the fastening part, as well as in positive engagement with the guide element. Due to this measure, the displacement force applied by the displacement element is introduced directly on the one hand into the fastening part, on the other hand into the guide element. Since this minimizes the distance between the point of introduction of the displacement force into the fastening part and the guide surface, the band according to the invention has a significantly lower tendency to jam during the displacement process.

In a structurally particularly preferred embodiment, the displacement element comprises a threaded spindle. A shift by rotary actuation of this threaded spindle is thus infinitely possible.

In a first embodiment, the threaded spindle can be arranged fixed in its longitudinal direction with respect to the fastening part and, with its external thread, engage with the guide element. In this embodiment, the threaded spindle moves together with the fastening part during rotational actuation.

In an alternative embodiment of the band arrangement, the threaded spindle is arranged fixed in its longitudinal direction with respect to the guide element and is in engagement with the fastening part with its external thread. In this embodiment, in the case of the displacement of the fastening part produced by rotational actuation, the threaded spindle remains stationary relative to the guide element and thus to the fastening surface.

In order to bring about the stationary position in its longitudinal direction either to the fastening part or to the guide element, in a first, preferred embodiment the threaded spindle has an annular groove, into which either an fixing part or arranged on the guide element fixing projection engages positively.

In a second, preferred embodiment of the band arrangement according to the invention, the threaded spindle is rotatable about its longitudinal axis in a receptacle which is preferably arranged in the guide element.

In order to fix the threaded spindle in its longitudinal direction, this receptacle preferably comprises two mutually spaced abutment surfaces on which the threaded spindle rests, each with one end face.

In order to further reduce the risk of jamming and to improve the achievable with the tape assembly positioning accuracies while easy manufacturability, the guide element are preferably about double-T-shaped and the guide recess formed approximately complementary thereto.

The attachment of the guide element to the attachment surface can basically be done in any conceivable manner, in particular also by a direct screwing, for example by means of a self-tapping screw element, since it does not have to be displaced or released for the purpose of adjustment with respect to the attachment surface. However, it is particularly preferred to provide in each of the crossbars of the double-T-shaped guide element at least one bore for a fastening means such as a fastening screw. In particular, in each case a bore can be provided at each end region of the crossbar, so that the guide element with the help of four fastening means on the mounting wall attachable and thus suitable for introducing particularly high holding forces on the band assembly in the mounting surface. In order to further reduce a risk of jamming during the displacement process, the threaded spindle is arranged in a first preferred embodiment approximately in the middle of the connecting bar of the double-T-shaped guide member and engages with about half of its cross section in a provided on the fastening part Recess, with about the other half its cross-section in a recess provided on the guide element a. In the recess of the fastening part is then the fixing projection, in the recess of the guide element to a thread of the threaded spindle complementary partial thread. Or it is provided a reverse arrangement, in which the fixing projection in the recess of the guide element, the partial thread are in the recess of the fastening part.

In a second, preferred embodiment of the band arrangement according to the invention, the receptacle for the threaded spindle comprises a receiving slot arranged approximately in the longitudinal center of the connecting bar, which is adapted to the dimensions of the threaded spindle such that a part of the outer circumference of the threaded spindle protrudes on opposite sides of the receiving slot. As a result of this measure, the force transmission between the guide element and the fastening part takes place substantially symmetrically with respect to the longitudinal central axis of the guide element and the fastening part, whereby the risk of jamming during the adjustment process is further reduced.

In order to be able to bring the threaded spindle into engagement with the fastening part, it is often sufficient if each protruding from the receiving slot part of the threaded spindle has the outer circumference of an at least 45 ° -Kreisausschnitts. Then has the attachment part - as particularly preferred - complementary to the external thread of the threaded spindle formed partial thread, in which the two engage from the receiving slot parts, so on the one hand a particularly secure positioning of the fastening part to the guide element with the help of the threaded spindle ensures, on the other hand, the threaded spindle positioned by the partial threads, so that it can be dispensed with their axial fixation in the receiving slot. So that the fastening part can not be accidentally completely disengaged from the guide element during a displacement process, the band arrangement preferably comprises a stop for limiting the maximum displacement path. This stop may be provided on the connecting bar of the double-T-shaped guide element approximately opposite the threaded spindle. It is arranged either on the fastening part or on the guide part and comprises a projection which engages in a recess provided on either the guide element or on the fastening part.

In order to reduce the risk of jamming of the fastening part on the guide element even at very high sash weights, means for Gleitreibungs- and / or clearance reduction between the fastening part and the guide member are preferably provided.

To form these means, for example, the guide element can be designed to be spreadable so as to be able to compensate for a possible clearance based on manufacturing tolerances between the guide element and the fastening part.

Surprisingly, it has been found that, in particular, a very effective sliding friction reduction can be achieved if the abutting surfaces of the fastening part and the guide element are formed by different materials.

Experiments have shown that clamping of the fastening part on the guide element during the displacement is surprisingly effectively prevented when the surface of either the fastening part or the guide element is formed by an anodized layer and the surface of the respective other guide element or fastening part is formed by a plastic layer , These different surface textures can be realized in production very simply by the fact that the fastening part and the guide element are initially anodized in the band-based aluminum-based alloys and then powder coated to achieve the desired finish, either in the fastening part, or in the Guiding a powder coating of the contact surface to the other component is prevented or removed in a coating following the further manufacturing step again. In the drawing, two exemplary embodiments of the inventive band arrangement are shown by way of example. 1 shows a perspective view of the first exemplary embodiment of the band arrangement according to the invention, mounted on a profile:

Displacement extreme position.

Of the designated as a whole with 100 first embodiment of a band assembly according to the invention only a band part 1 is shown in the drawing. It may be both the wing band part attached to a wing and the frame band part attached to a frame.

The band part 1 has a fastening part 2 and a hinge part 3. The fastening part 2 and the hinge part 3 are integrally connected to one another via an angled connection region 4, the dimensions of the connection region 4 being adapted to a sealing projection 5 of a hollow chamber profile 6, as can be seen in particular in FIGS. 4 to 6.

The fastening part 2 has a substantially flat underside 7, which faces a fastening surface 8 of the hollow chamber profile 6.

Into the fastening part 2, a guide recess 9, which is approximately double T-shaped in plan view, is incorporated. In it engages a guide member 10 of a substantially complementary shape, such that it forms a substantially play-free sliding fit with the guide recess 9.

The guide element has at the end regions of the crossbars 1 1, 1 1 'in each case a bore 12 for a fastening means 13. In the embodiment shown in the drawing, the fastening means 13 is formed as a self-tapping fastening screw 14. This intervenes to avoid cold spots in two opposing insulating webs 15, 15 'of the hollow chamber profile 6, so that the guide element 10 is fixedly connected to the hollow chamber profile 6. A displacement of the fastening part 2 perpendicular to the fastening surface 8 and a displacement of the hinge part 3 perpendicular thereto to a hinge axis S defined by the hinge part 3 - also called "horizontal adjustment" - can be achieved without loosening the fastening part 2 from the hollow chamber profile 6 by displacing the hinge part Fastening part 2 on the guide element 10 done.

In order to effect the displacement and to fix the fastening part 2 relative to the guide element 10 in a desired displacement position, a displacement element 16 is provided, which is in positive engagement with the fastening part 2 and the guide element 10. It is designed as a threaded spindle 17 with an external thread 18, which is divided by an approximately in the middle of the longitudinal extent of the threaded spindle arranged annular groove 19 into two threaded portions.

The threaded spindle 17 engages on the one hand in a semi-circular in cross section recess 20, which is arranged in the middle of the connecting bar 21. In the recess 20, a fixing projection 22 is provided, which engages in the annular groove 19 of the threaded spindle 17 with little play.

Further, the threaded spindle 17 is with its external thread 18 in engagement with a complementary half-thread 23, which is formed in a recess 20 opposite to the recess 24 of the guide member 10. On the opposite side of the recess 24 of the connecting bar 21, a projection 25 is formed, which forms part of a stop 26 for limiting the maximum displacement path V. The second part of the stop 26 is formed by a projection 27 in a recess 20 opposite recess 28 of the fastening part 2. The projections 25, 27 are dimensioned such that in the left extreme position shown in Figs. 4 and 6 between the projections 25 and 27 remains a free space which corresponds to the maximum adjustment path V. As is apparent from the drawing, by means of rotary actuation of the threaded spindle 17, the fastening part 2 with the hinge part 3 formed thereon can be displaced between the extreme left position X1 shown in FIG. 4 and the right extreme position X2 shown in FIG. In order to reduce the risk of jamming from the fastening part 2 to the guide element 10, the abutting surfaces 29, 30 of the guide recess 9 and of the guide element 10 are formed of different materials. For this purpose, the guide element 10 may for example be completely plastic-coated, whereas the surface 29 of the guide recess 9 is formed by an anodized layer.

Another, exemplified embodiment of an inventive arrangement, which is referred to as a whole with 200, is shown in Figs. 9 to 12. Designated components have been given the same reference numerals but increased by a numerical value of 100. In order to avoid repetition, only the differences which the second exemplary embodiment 200 has over the first exemplary embodiment 100 will be discussed below. In the second embodiment 200, the ends of the crossbars 1 1 1, 1 1 1 'are provided with a regular arrangement of a plurality of grooves 139 which extend in the direction of the bores 1 12 of the guide member 1 10. As a result of this measure, the frictional force acting between the adjusting element 10 and the fastening part 102 during an adjusting process is reduced. In addition, each end of a bore 1 12 radially outwardly directed longitudinal slot 141. Since the fastening screws 14 are designed as countersunk screws and the bores 12 have a countersink 142 adapted thereto, tightening the fastening screws results in the spreading of the respective end of the crossbeams 11 1. In order for the spreading to take place as evenly as possible, the countersinking can be arranged approximately in the center of the bore.

Approximately in the longitudinal direction center of the connecting bar 121 is a receptacle 131 in the form of a receiving slot for supporting the threaded spindle 1 17 in incorporated the connecting bar 121. The slot width is only slightly larger than the length of the threaded spindle 1 17, so that their end faces 134, 135 abut substantially without play on the contact surfaces 134, 135 of the receiving slot 136.

The diameter of the threaded spindle 1 17 is chosen so that it protrudes on both sides with a part of its outer periphery of the receiving slot 136, wherein the respective partial circumference corresponds to the outer periphery of an approximately 45 ° -Kreisausschnitts α.

With its external thread 1 18, the threaded spindle 1 17 is in engagement with complementary to the protruding parts formed partial thread 138, 138 ', which are provided in the fastening part 102. As is apparent in particular by comparison of FIGS. 1 1 and 12, in which Fig. 1 1 a left in this drawing, Fig. 12 show a right extreme position of the fastening part 102 according to this drawing, by rotation of the threaded spindle 1 17 done. The threaded spindle is designed to be suitable for applying a suitable rotary tool by means of an actuating opening provided on the connecting bar 121. For example, it has a central hexagon socket.

The maximum displacement is limited on the one hand by a contact of the fastening part 102 on the mounting surface 108 of the hollow chamber profile 106, on the other hand by stops 126, which are now located at the longitudinal ends of the connecting bar 121.
