Description

The invention relates to a hinge with an angular and height-adjustable lifting and lowering device for doors or windows, especially for glass swing doors, with a first and a second Hinge part that is rotatably connected to each other about a vertical axle bolt are and each have a bearing sleeve surrounding the axle bolt, which in a matching recess on the associated band part detachable is arranged and has an end face profiled support surface such that in the event of twisting, the upper of the two parts of the hinge relative to the other Band part is raised, both bearing sleeves on the band parts by means of Screw elements can be fixed in the direction of rotation.

In a known hinge for doors or windows (DE 200 10 009 U1) has a cylindrical recess on each of the two belt parts provided in which the axle bolt with the bearing sleeve surrounding it can be locked in the direction of rotation by means of a screw element. At each of the Both bearing sleeves have a support surface that is profiled on the end face Twisting the band parts slide on each other so that the rotatable arranged upper band part opposite the fixed lower band part is raised accordingly. Both bearing sleeves are essentially identically formed and have a stepped sleeve head, with which each bearing sleeve is stepped in a correspondingly stepped manner cylindrical recess on the associated band part essentially is kept free of play and is fixed by means of a fastening screw. The lower bearing sleeve is in the cylindrical recess on the lower band part fixed by a radially acting grub screw, while the upper Bearing sleeve in the stepped recess on the top Band part with the interposition of a rotation lock ring by a in Direction of the axis bolt acting clamping screw is set. The Fastening or tensioning screw projects through a through hole in a cover wall covering the recess of the upper band part and is in an axial threaded hole of the axle bolt is screwed in, the upper Front side is supported against a radial shoulder of the bearing sleeve. This causes the bearing sleeve with support ring by means of the fastening or Clamping screw and the face of the axle bolt in the recess pulled up and clamped to the rotatable belt part.

In this known hinge band, the two bearing sleeves with the associated support rings have essentially similar outer contours. For bracing and releasing the two bearing sleeves from the bracing on the lower part of the band and on the upper part of the band, in particular as for Angle adjustment or for setting the respective end positions at Adjustment of the lifting / lowering device is required, however, in each case Various technical means are required, which on the one hand have a number of require differently shaped components and on the other hand also Assembly and disassembly of the various components complicate.

The invention has for its object a hinge according to the Preamble of claim 1, the angle adjustment and Height adjustment when mounting the lifting / lowering device is suitable to design the smallest possible number of different components so that both for stepless angle adjustment and for height adjustment the upper band part practically identical to the lower band part Components can be used, which are also on the two parts of the belt mirror image of one perpendicular to the longitudinal axis of the axle bolt level can optionally be arranged such that they are from the two ends of the opposite in the longitudinal direction of the axle bolt the two parts of the band tied in an identical manner, released and after one Adjustment can be clamped again.

This problem is solved with a hinged belt after Preamble of claim 1 according to the invention essentially by that each of the two bearing sleeves is conical from the support surface has tapered outer jacket and on the associated band part in the matching recess by means of a in the bearing sleeve along the Hinge axis screw-in lifting and countersunk screw self-locking can be tightened.

Particularly advantageous developments of the invention are in claims 2 marked to 14.

The invention has the advantage that the two identical conical designs shaped bearing sleeves in the recess on the respective band part determined solely by friction in the selected clamping position by lifting and screwing into the end of the bearing sleeve Countersunk screw in the recess of the band part in question is tightened.

To release the bearing sleeve from the clamping position, it is only necessary to unscrew the lifting and countersunk screw from the bearing sleeve so far that they are arranged in the area of action of one end of the band part Support screw arrives, whereupon the support screw is actuated and so far in the recess is screwed in so that it overlaps the bearing sleeve Countersunk screw from the recess on the band part in the direction of Axle pin pushes out. This happens in both bearing sleeves identical way. It is also sufficient to connect the two parts of the belt a simple cylindrical axle bolt that fits into the recesses on the two bearing sleeves arranged coaxially to one another can be used loosely, without lateral tensioning of the axle bolt with one of the two Band parts would be required.

It when the outer jacket of each bearing sleeve in one is particularly advantageous Angle of about 1 ° to 2 ° is inclined, so that each of the two conical Bearing sleeves by loosening the lifting and countersunk screw as well as an axial one Pressurizing the lifting and countersunk screws in the direction of the Hinge axis from the bracing in the recess on the relevant Band part is detachable.

A technically particularly safe and easy to assemble and adjust Handling option for loosening and adjusting the angle of the bearing sleeve on the associated band part is also achieved in that the lifting and Countersunk screw is passed through an opening in a crosspiece at the inner end of the recess for the bearing sleeve on the band part is arranged so sunk that the lifting and countersunk screw after Loosen and make a few turns using a support screw in the direction of the Hinge axis that can be loaded into a screw thread on a head-side recess for the recessed reception of the lifting and Countersunk screw can be screwed onto the hinge part. This also leads to a particularly compact design, which is further improved by the fact that the lifting and countersunk screw with a cylindrical screw head and one frontal, central, profiled recess for the intervention of a so-called Inside hexagon key is formed.

In the preferred embodiment of the invention it is further provided that the Recess for receiving the conical bearing sleeve is conical is rejuvenated. This results in a particularly secure and firm frictional connection each of the two bearing sleeves on the associated band parts.

It is also particularly advantageous that the support screw also has an axial arranged, profiled through opening for the Allen key for loosening the lifting and countersunk screw, which at the same time as Hexagon opening for the engagement of a correspondingly larger dimension Allen key for loosening and tightening the support screw is trained.

The support screw expediently has a cylindrical screw head, with which they are attached to an inner shoulder at the front end of the recess for the recessed arrangement of the lifting and countersunk screw comes into contact that its end face with the peripheral edge of the recess on the band part flees. This makes it possible in a simple manner that the support screw on the hinge part through an insertable into the internal hexagon opening Cover cap is protected.

In addition to the angle adjustment, the hinge strap also allows one Height adjustment of the upper hinge part connected to the door leaf opposite the lower part of the belt, which either on a building wall be fixed to a fixed shower cubicle wall or similar can. To adjust the height of the lifting / lowering device is therefore after a Another essential feature of the invention provided that for Height adjustment of the lifting / lowering device at least one of the two conical bearing sleeves on the associated band part of an adjusting sleeve is surrounded with a cross bar and an external thread, which with the External thread in a matching internal thread on the relevant The belt part can be screwed in and the height of the belt part can be adjusted and is fixable. Just like in the first embodiment for the Angle adjustment is in this second embodiment for the Height adjustment therefore provided that the adjustment sleeve with the crossbar has an H-shaped longitudinal section. Besides, after one Another feature of the invention provided that the adjusting sleeve on the one of its two ends, on the cross bar adjacent end has an internal thread for the support screw.

Furthermore, the internal thread for the adjusting sleeve is on the associated band part over the entire axial length of the band part from one end to the other continuously formed such that the adjusting sleeve of each of the two Ends can be screwed into the band part. To secure the Height adjustment can be the adjustment sleeve according to another feature of Invention with a laterally penetrating the wall of the band part Grub screw or the like on the belt part in any height position be clamped. If necessary, the adjustment sleeve can also be provided by a Securing agent based on a pressure sensitive adhesive or the like on the relevant band part.
