Device for connecting a displaceable element to a guide device

Apparatus for guiding displaceable elements. The apparatus of this invention serves for guiding sliding elements, particularly doors, windows, dividing walls, shutters and coverings, that are slidably journalled on an upper side thereof in a first guide and are guided on a lower side thereof with an additional guide which is in turn connected with the floor or a side wall, with the additional guide including at least one elastic element which is adapted for direct force transfer or force transfer via transfer means, so as to press against the underside of the sliding element, so that the underside of the sliding element is retained by the additional guide free from play, thereby avoiding objectionable noises, both at rest and during displacement of the sliding element.

A sliding element slidable on trolleys along a rail comprises a swing door swivellably suspended on a top frame strip and having, in a bottom frame strip (6') an anchoring device having a hinge stud (16) which can be lowered to engage with a receiving bush rotatably anchored in the floor. The hinge stud (16) is formed on a wedge-shaped hinge part (17) of metal which is guided for vertical sliding on a guide section (18) in the bottom frame strip (6') and engages slidably along a slide section (19) with a matching section (22) of a likewise wedge-shaped lowering part (23) of plastics material. Said lowering part is provided, in a recess (24), with a driving nut (25) which engages through a self-locking thread connection with a lowering bolt (27) which is positively connected by way of a bevel gear unit (29) to an operating pin (30) suitable for engagement of a hexagon socket key. A torque-limiting claw clutch may be inserted between the bevel gear unit ( 29) and the lowering bolt (27). The hinge part (17) can be moved up and down by turning the operating pin (30) but in every position is unable to be displaced even by high forces exerted by the receiving bush on the hinge stud (16).

Two mutually adjoining profile pieces (1a) of equal cross-section are connected by means of a coupling piece (16) which overlaps both of them and is situated in a coupling groove (15). The convexly arched floor of the latter is formed by the underside of a crossbar (5), the top side of which forms a running surface (6) for bearing rollers of running mechanisms. In the downward direction, the coupling groove (15) is limited by lateral holding strips (18a,b) exhibiting flat, inwardly inclined holding surfaces (19a,b), which point towards the floor of the said coupling groove and against which are pressed corresponding contact strips (20a,b) of the coupling piece (16), which coupling piece is braced against the holding strips (18a,b) of each of the profile pieces (1a), by means of, in each case, two tapping screws (17b) pressing against the floor of the coupling groove (15). At the bottom, the coupling groove (15) is adjoined by a guide groove (9) for receiving guide rollers. For the purpose of enabling a particularly stable connection of the profile pieces--for example in the case of a rail supported only punctually by means of sliding blocks, which are disposed in a fastening groove and in which threaded bolts engage--the profile pieces can be provided with two coupling grooves disposed at a distance apart one above the other.
