Dk invention relates to a journal bearing Wf about a lateral vertical axis pivotable hill of doors, lasbesondere of swing doors, wherein the pin EOL & Eerbüchsc in cioctn is disposed in the Lagerbalterung guided carriage which tuen Ait oner spindle Rotter mi of both ends in the Lagcrhalterung mounted UOD by means of a Clamping screw lockable screw spindle is mounted perpendicular to the Schwcnkacbs «Bchiebbar

Such a journal bearing is known, bed the a Medeeschrtvbe provided as a clamping screw is that next to the screw spindle in cioc wall of the Fitting is screwed in parallel to the screw spindle with its tip against one at the end Screw spindle provided pushes the shear ring. the Clamping effect of such an arrangement is not special big. When the screw spindle as the end opposite the headless screw, something Play in the camp asked, the grub screw must be like that be widely emgedrebt that they the screw spindle and the slide guided by the spindle as well the entire load of the TIk pressing on this rubble moves in the axial direction of the screw spindle, bts the play at the end of the screw spindle opposite the Madea screw has disappeared « if the modem screw should have a clamping effect at all. Normally, however, it is not possible With a small Madcroch attacking outside the axis of the screw spindle, the screw spindle end the screw spindle connected to it, through the door given large loads do not move. The grub screw is therefore usually only so far pulled, bit it rests against the seat ring. Shark now the spindle actually on the opposite one At the end of some play, the screw spindle will be at Use of the fitting at some point in a row move this game axially so that the shoulder calm comes free from the tip of the Madenvchraobc. Then the grub screw no longer exerts a clamping effect on the screw spindle, and the adjustment device has become ineffective.

The invention is therefore based on the object of improving the locking device of the screw spindle in such a way that perfect fastening is always possible even if there is an axial spindle of the screw spindle. The invention consists in that the clamping screw rom fixing the screw spindle engages one end of the screw spindle radially at atm and that the screw spindle is mounted in the vicinity of the end at which the clamping screw engages in the bearing aging with play in the attack direction of the clamping screw

Rotated, so that the carriage 8 with the bearing bush in the direction of the Double arrow 19 moves. If the right position is reached, so this setting is secured in that the clamping screw 15 is screwed in. These presses against the ring 16 and thus the end 7 against the inner wall of the bearing bore 4, so that further unwanted rotation of the screw spindle is excluded. In addition, this small transverse displacement of the screw spindle 5, the thread of the screw spindle in the inner

thread of the bore 9 jammed somewhat, so that the frictional resistance caused by a further rotation of the screw spindle also counteracts. Finally, through the low Transverse movement of the screw spindle 5 pushes the shoulders of the slide 8 against the inner surface of the belt 2 pressed, whereby the frictional resistance against a displacement of the carriage 8 increases further. The flanks 20 of the sliding block-like approach

ίο 13 of the carriage 8 run, as indicated in FIG. 3 is inclined, so that when pressing the carriage 8 against the band 2 of the fitting still one Wedge effect between the approach 13 of the carriage 8 and the band 2 occurs.

Claims (4)

Rung form of the invention, the clamping screw not directly on the end of the screw spindle shaft, but on a ring attached to the screw spindle. In the drawing, an embodiment of the invention is shown. It shows F i g. 1 shows a longitudinal section along the line I-I of FIG. 2 by an embodiment of the journal bearing according to the invention, FIG. 2 shows the top view of this embodiment and FIG. 3 shows a section along the line III-III of FIG. 2. In the embodiment of the invention shown in the drawing, the journal bearing has a band 1 which serves as a bearing holder and forms the outside of the fitting, to which a U-shaped band 2 is welded , riveted or otherwise rigidly attached. This band 2 has opposite bearing bores 3 and 4 on its legs, which are used to support a screw spindle 5, which has a screw head 6 at one end and a threadless shaft mounted in the bearing bore 4 at its other end 7. A slide 8 is guided on the screw spindle 5 by means of a bore 9 which is provided with thread over part of its length and has a threadless part 9 'at one end. The carriage 8 carries a journal bearing bushing with a needle bearing 10 and is slidably guided in the belt 1 in a recess 11 and in the lower part of the belt 2 in a longitudinal recess 12 in which a sliding block-like projection 13 of the carriage 8 engages. In the band 1, a clamping screw 15 is mounted in a threaded bore 14, the end of which engages the outer surface of a ring 16 which is pushed onto the shaft-like end 7 of the screw spindle 5 and held in place by a nut 17. The bearing bore 4 for the end 7 of the screw spindle 5 has a play 18 at least in the direction in which the clamping screw 15 engages. To adjust the bearing, the screw spindle 5 is rotated at its screw head with the aid of a screwdriver or the like, so that the carriage 8 with the bearing bushing moves in the direction of the double arrow 19. Once the correct position has been reached, this setting is secured in that the clamping screw 15 is screwed in. This presses against the ring 16 and thus the end 7 against the inner wall of the bearing bore 4, so that further unwanted rotation of the screw spindle is excluded. In addition, with this slight transverse displacement of the screw spindle 5, the thread of the screw spindle is somewhat jammed in the internal thread of the bore 9, so that the frictional resistance caused thereby also counteracts further rotation of the screw spindle. Finally, due to the slight transverse movement of the screw spindle 5, the shoulders of the slide 8 are pressed against the inner surface of the belt 2, as a result of which the frictional resistance against a displacement of the slide 8 is further increased. The flanks 20 of the sliding block-like approach of the slide 8 run, as in FIG. 3 is indicated, obliquely, so that when the carriage 8 is pressed against the band 2 of the fitting, a wedge effect between the projection 13 of the carriage 8 and the band 2 occurs.
