Definitions
- the present invention relates to a floor-embedded locking device for a door, in particular for an all-glass door, comprising a pivot pin device.
- the pivot axis of a door such as an all-glass door may comprise a device wherein a pivot pin of a floor-embedded locking device is non-rotationally received so that said pivot pin is pivoted together with a pivotally supported receiving bush when the door is pivoted, with said receiving bush being surrounded by a cam plate which is engaged by a spring-mounted, longitudinally displaceable piston.
- the pivot pin is manufactured with such a length that a sufficiently long portion of it protrudes upwardly from the floor-embedded locking device, and is then installed in the floor-embedded locking device.
- Pivot pins for floor-embedded locking devices may comprise, for example, a hexagonally formed, conically extending shank which engages into a receiving bush having a matching internal shape.
- this design enables the pivot pin to be non- rotationally received in the receiving bush, the precise dimensions of the particular application need to be known beforehand, since the length of the pivot pin portion protruding from the floor-embedded locking device may not be adjusted at the assembly site. As a result, it is often necessary to provide a choice of pivot pins with different shank lengths at the assembly site.
- the pivot pin must be replaced by another one having a different length when the distance between the upper edge of the floor-embedded locking device and the lower edge of the door is changed lateron, for example due to the provision of another floor covering.
- a pivot device for a floor-embedded locking device is known from DE 30 33 363 Al, with the pivot pin being axially fixed at a seat portion by means of screws and coupling members so that it is non-rotationally supported.
- the pivot pin comprises a plurality of notches extending transversely to its longitudinal direction, at which notches the pivot pin may be cut to the required length.
- it is also necessary to provide pivot pins with sufficiently long shanks at the assembly site, which are then assembled at the required length. If there is a change lateron in the dimensions of the assembly site, for example an alteration of the floor height, a new pivot pin which has the required new length has to be provided.
- the floor-embedded door locking device is provided with a pivot devisee comprising a pivot pin with an annular collar and a noncircular shank formed adjacent to said collar, said shank having a uniform cross-section along its length, and a rotatably supported receiving bush whose shape matches that of the shank and wherein the pivot pin is received in a non-rotational and axially displaceable manner.
- the shank is formed as a sleeve comprising a slotted expansion portion which is engaged by a threaded bolt extending in an axial hole of the pivot pin, by means of which threaded bolt the expansion portion may be radially expanded so that it is clampingly locked in the receiving bush.
- the present invention enables the shank of the pivot pin to be inserted into the receiving bush by a length required by the dimensional features of the particular application, i.e. so that the pivot pin protrudes from the floor-embedded locking device by such a length that the respective door may be received thereon as required.
- the threaded bolt is threaded into the axial hole
- the expansion portion of the shank which is formed by slots provided in the shank, is radially expanded so that it is clamp-fitted in the receiving bush.
- a particular advantage of the device according to the present invention consists in the fact that the pivot pin may be axially displaced in the receiving bush by removing or unscrewing the threaded bolt from the axial hole in the shank.
- the pivot pin merely has to be unlocked from its present clamping position, and clamp-fitted anew at the newly required position in the receiving bush.
- one or more plain washers, rings or the like may be placed be €ween the annular collar of the pivot pin and the receiving bush, which may also be easily removed if no longer required.
- the pivot pin is not only held by means of a clamping fit, but in addition its annular collar is positively supported on the washer placed on the receiving bush and under the annular collar.
- the expansion portion of the shank extends from the free end of the shank to the centre thereof as seen in the longitudinal direction.
- the expansion portion may also extend to a position close to the annular collar of the pivot pin, or it may extend from the longitudinal centre of the shank in both directions towards the ends thereof, terminating at a distance from the two ends of the shank so that it is formed approximately in the central .third of the length of the shank.
- the axial hole of the pivot pin is- provided with an internal thread as well as a conical countersinking that is formed in the expansion portion extending from the free end of the shank and tapers towards the annular collar.
- the external thread of the threaded bolt engages the internal thread of the axial hole, and the threaded bolt comprises a conical head portion at its free end which abuts against the inner peripheral wall of the conical countersinking.
- the axial hole of the pivot pin is formed as a cylindrical counterbore within the pivot pin and has a shoulder formed adjacent to the bottom of the bore.
- the counterbore is adjoined by a portion of the hole which is smaller in diameter than the counterbore and which terminates, within the expansion portion extending from the free end of the shank, in a conical countersinking tapering towards the annular colla-r.
- the threaded bolt according to this embodiment is designed as a head screw which has its head supported on said shoulder at the bottom of the bore, and which has a conical locknut screwed onto its thread, said locknut abutting against the inner peripheral wall of the conical countersinking.
- the locknut When the threaded bolt is being rotated, the locknut abutting against the peripheral wall of the conical counterbore is moved upwardly towards the screw head so that it causes the expansion portion of the shank to expand.
- the conical surfaces of the locknut and the counterbore may be designed such that the locknut is prevented from rotating together with the threaded bolt when the latter is being rotated.
- the axial bore of the pivot pin comprises a threaded portion and, within the expansion portion, a conical portion which tapers towards the end of the shank.
- the threaded bolt is threaded into the threaded portion and abuts against the inner peripheral wall of the conical portion.
- the expansion portion, and thus the conical portion tapering towards the end of the shank may be provided such that they extend from the approximate centre in the longitudinal direction of the shank to the free end thereof.
- the expansion portion comprising the conical portion tapering towards the end of the shank may also be formed in the central third of the length of the shank so that the shank is not expanded at its free end but at its centre, resulting in a convex shape.
- the threaded portion is formed at least partially along the conical portion, with the threaded bolt being conical as well.
- the conically formed threaded bolt is threaded into the at least partly threaded conical portion, it abuts against the inner peripheral wall of the conical portion and causes the latter to expand.
- the threaded bolt comprises a tool engaging recess at its end facing the end of the pivot pin, which may be formed as a slot, a cross recess, a hexagon socket, a square socket, or an internal serration profile.
- the threaded bolt may, for example, be provided with a square journal at its free end facing the free end of the pivot pin, which may be engaged by a tool having a square socket so that the threaded bolt may be operated.
- the shank of the pivot pin has a hexagonal outer shape
- the receiving bush has a hexagonal inner shape.
