Definitions

  • the invention relates to a pivot bearing for doors, in particular for swing doors, which is attached to the upper door edge opposite a floor closer, with a pivot hinge consisting of an upper and lower part, the pivot of which is displaceably arranged in a guide of the pivot hinge part by means of an adjusting device.
  • the pivot hinge of such a pivot bearing usually consists of an upper part and a lower part, the lower part being installed in the upper door leaf edge opposite the floor closer and the upper part fittingly above it in the door frame.
  • the pin of such a hinge is axially displaceable in the top part of the hinge for installing and / or removing the door in such a way that it can be sunk completely into the door frame for installing the door, while after the door is inserted it is again axially adjusted downwards and in the lower hinge part inserted in the door leaf can be immersed.
  • DE-GM 1 680 224 In order to be able to bring about this axial displaceability of the pin, a quite complex adjustment device has hitherto been used (DE-GM 1 680 224).
  • This consists of a two-armed lever, which is pivotally mounted in a bracket of the upper part of the pintle around a horizontal bolt.
  • One lever arm interacts with an adjusting screw, which in turn can be screwed into the upper part of the journal in the vertical direction.
  • This lever arm is fork-shaped, encompasses a sliding block which is coupled to the lever arm by lateral pins and is rotatably but non-displaceably mounted on the cylindrical plate of the adjusting screw.
  • the other lever arm first passes through an elongated slot in the guide for the pin and projects with its front free end into a slot in the pin.
  • the pin is then coupled to a lever arm via a cross pin. The pin can be moved up and down axially by actuating the set screw.
  • the invention has for its object to provide a pivot bearing of the type characterized in more detail above, which can perform all the functions of known embodiments, but is such that the door can be assembled or disassembled even in the closed state - that is, without closing force. It should also ensure a compact, nested design of the adjustment of the pin and finally the manufacture of the pivot bearing should be possible less expensive than before.
  • this goal is essentially achieved in that the adjustment device of the pin is assigned to the guide of the pin hinge upper parts in a nested design.
  • the pin is axially displaceable in the guide due to the radial movement of a threaded bushing encompassing it in some areas.
  • the design of a pivot bearing according to the invention has considerable advantages over the known.
  • the fact that the adjustment device of the pin is assigned to the guide of the upper part of the pin band results in a compact design. There is no need to use a two-armed lever and an adjusting screw located away from the guide. This also eliminates the need for a special bearing block for the two-armed lever and an additional bearing point for the set screw.
  • the pivot bearing according to the invention When the pivot bearing according to the invention is used as intended, it is advantageous that the door can be assembled or disassembled in the closed state. This also eliminates the need to apply a closing force and, finally, the pivot bearing according to the invention can also be produced more cost-effectively than the known embodiments.
  • the threaded bushing be rotatably but axially immovably supported in a receiving space of the housing of the upper part of the journal, to have a steep internal thread for engaging a pin-like projection of the journal and to have an engagement part for an actuating tool.
  • a rotation of the threaded sleeve, which, as mentioned, is secured against axial displacement, has the consequence that the pin-like projection and the internal thread of the pin are displaced at a high pitch.
  • the collar of the threaded bushing can have a plurality of engagement points designed as recesses for an actuating tool designed as a hook wrench.
  • the rectangular-shaped recesses which are open towards the front are expediently arranged in a regular arrangement over the collar of the threaded bushing.
  • the hook of the hook wrench optionally interacts with one of these recesses.
  • the pin carries in its free upper end protruding from the threaded bushing a further notch pin which engages with its free end in a longitudinal slot in the housing of the upper part of the pin.
  • the pin is secured against rotation via this second plug-in notch pin, but is arranged axially displaceably in the housing of the upper part of the pin.
  • the collar of the threaded bushing is thinner than the usual air gap between the door and door frame, but thicker than the hook wrench which cooperates with its recesses. It is therefore possible to use the hook wrench to get between the door leaf and door frame and to turn the threaded bushing even when the door is closed.
  • the adjusting device of the pin in particular the threaded bushing, is assigned a safety device which prevents unauthorized adjusting.
  • the safety device is designed as a locking plate which has a nose which engages in one of the recesses in the collar of the threaded sleeve and thus prevents the threaded sleeve from rotating.
  • one of the fastening screws that fix the top hinge part on the door frame can also be used to hold the locking plate.
  • the pin has a thread on its peripheral surface, at least in some areas, into which the counter thread of a screw spindle or the like. engages, which in turn is arranged laterally next to the pin and has an engagement point for an actuating tool which projects into the air gap between the door and the door frame.
  • the lower part of the pin which cooperates with the lower part of the pin hinge, is expediently left free of the thread.
  • 10 denotes a door, which is associated in a known manner with a floor door closer 11 embedded in the floor 12 of a known type. With 13, the connection means between the floor closer 11 and the door are generally designated. These parts can have a structure known per se and can also cooperate with the door 10 in a manner known per se.
  • a pin hinge lower part 14 is attached in the door 10.
  • a more detailed description of the design of the lower hinge part 14 can be dispensed with, as well as the attachment to the door 10. It is only essential that this lower hinge part 14 must be equipped with a receiving space for the spigot of the upper hinge part.
  • the pin of the upper part of the pin hinge can dip into the receiving space of the lower part of the pin hinge 14 in a manner still to be described and thus produce a coupling to the door 10. If required, uncoupling is also possible by moving the pin out of the lower part 14 of the pin hinge.
  • the upper part of the journal is generally designated 15. It is accommodated in the ceiling or the door frame 16 in a manner known per se and therefore not described in detail. His training is best seen from Figs. 2 and 3 of the drawing. It follows that the upper part 15 of the pintle has a housing 17 with a receiving space 18 which is essentially hollow-cylindrical. Transversely to the housing 17, this has a fastening part 19 that is integral with it. In the selected exemplary embodiment, this is designed in the form of a plate and, with respect to the housing 17, has regions of different lengths and arranged on opposite sides, as can be seen in FIG. 2 and the drawing.
  • a threaded bushing 20 is arranged in the lower part of the receiving space 18 in the lower part of the receiving space 18 in the lower part of the receiving space 18 .
  • the threaded sleeve 20 is rotatable within the receiving space 18; however, an axial movement of the threaded bushing 20 is prevented by a locking ring 21.
  • This locking ring 21 engages partly in a recess 22 in the boundary walls of the housing 17 and partly in a further recess 28 of the threaded bush 20, as can best be seen from FIG. 3 of the drawing.
  • the size and design of these two recesses is therefore adapted to the circlip 21 used.
  • the threaded bushing 20 has a central opening, not shown, through which a pin 23 passes.
  • a first notch pin 24 is let into the pin 23 and engages with its front end protruding from the pin 23 into a thread 25 of the threaded bushing 20. This is a thread 25 with a large pitch, as can best be seen from FIG. 5 of the drawing.
  • a second notch pin 26 inserted, which is kept slightly longer than the notch pin 24, because the front free end of this second notch pin should engage in a longitudinal slot 27 of the housing 17 .
  • This second notch pin 26 secures the pin 23 against rotation, so that only an axial stroke of the same is possible.
  • the lower area of the pin, which projects out of the threaded bushing 20, is the area which cooperates with the lower part of the pin in the sense of a coupling. In the position of the pin 23 according to FIG. 3, it is in its lowest position.
  • the threaded sleeve 20 is - see FIGS. 4 and 5 of the drawing - equipped with a collar 29 which is arranged transversely to the longitudinal direction of the threaded sleeve 20.
  • Recesses 30 are provided in this collar, which are approximately rectangular in plan view and are open towards the front.
  • the recesses 30 are configured identically to one another, so that the regions of the federal government 29 which lie between them and which have remained standing have the same configuration as one another.
  • the collar 29 is held in one piece with the threaded sleeve 20.
  • the recesses 30 of the collar 29 of the threaded bush 20 are used to attack a tool. This is shown in FIGS. 6 and 7 and designed as a hook wrench 34. It follows from this that the handle of the hook wrench 34, which is not described in more detail, merges into a hook 35 via a curved connecting piece 36. The design and dimensions of this hook 35 are such that it fits into one of the recesses 30 of the collar 29 of the threaded sleeve 20.
  • the collar 29 of the threaded bushing 20 is advantageously kept somewhat thinner than the normal air gap between the door leaf and door frame, but somewhat thicker than the strength of the hook wrench 34. In this way it is possible, even with the door 10 closed, with the hook wrench 34 between the door leaf and door frame to twist the rifle sleeve 20.
  • a locking plate 32 is attached after completion of the assembly.
  • This locking plate 32 has an approximately rectangular shape, with a narrow nose 33 bent out of the base plane being provided on one narrow side. This nose 33 is precisely adapted to the dimensions of a recess 30 in the collar 29 of the threaded sleeve 20. So that a special - that is, additional - fastening element for attaching the locking plate 32 can be dispensed with, one of the screws 31, with which the fastening part 19 of the upper hinge part 15 is attached in the ceiling or in the door frame 16, is also used to fix the locking plate 32 used, as can be clearly seen from FIGS. 2 and 3 of the drawing.
  • the embodiment shown is only one example of realizing the invention and it is not restricted to this. Rather, many other designs and applications are possible. This applies in particular to the design of the threaded bushing 20 and the parts interacting therewith. It would be possible, for example, to provide the pin 23 with a thread on its peripheral surface at least in some areas. In such an external thread, the counter thread could Screw pin or the like arranged laterally next to it. intervene, which can be rotated using an operating tool, the surface of which lies in the air gap between the door leaf and door frame. It is expedient if, in this embodiment, the lower area serving the coupling with the lower part of the journal does not have an external thread.
