Description

The invention relates to a non-reversible height adjustable pedestal for offenfugig to be laid plates, especially for paving slabs or other coverings freely weathered terraces, balconies or the like, comprising a base plate with a plurality of molded, cylindrical bearing pedestals, each associated with a bearing base hollow cylindrical intermediate piece with side actuation extensions to the subject each intermediate piece of a twisting movement, cap-shaped pads, each having a support seated on an intermediate piece, the supports have a rotation and the height adjustment of the coming into contact with the plate underside pads via a thread mating between the bearing base, intermediate piece and an internal thread of the cap-shaped support, and with a joint cross according to the preamble of patent claim 1.

Height adjustable supports for offenfugig to be laid paving slabs on roofs with waterproofing, terraces or the like, for example, from DE 298 19 317 U1 or the DE 10 2006 034 163 A1 previously known. This known bearing is based on a base plate which carries at least one threaded bearing base, one with one end in the A bearing base on or screwed onto this threaded piece, which has approximately longitudinally an actuator in the form of a toothing on its periphery having a flange and mutually opposite threads at both ends and having a corresponding thread, against the base plate secured against rotation bearing piece for at least one the paving slabs to be laid. The bearing piece is screwed based on the aforementioned threaded piece. On the base plate also upright, flexible locking pins are present, which engage in the toothing of the actuator to effect a reverse rotation of the threaded part, so that an unwanted lowering of the bearing piece can be prevented. Moreover, the cited teaching discloses an embodiment according to which the detent pin can be identical to a guide pin arranged on the base plate, which passes in a conventional manner for preventing rotation of the respective abutment piece through a recess in a radial projection thereof.

On the application side, a protective layer and then the pedestal bearing according to the invention are laid one after the other on the finished roof seal. It then follows the placement of the plates and the insertion of joint crosses.

Suitably, the laying direction of the processes to the lining edges, the edge plates are adapted to the course of the edge. The individual pedestals are each arranged under the cross joint of four plates. A plate is at its corners on each of a plate bearing of four pedestals on.

Basically, the plate covering is laid in the slope of the roof seal. Due to the non-reversible, for example, up to 22 mm individually infinitely height-adjustable plate support tolerances in the plate thickness and in the pad are compensated, so that the surface of the pad is flat and steadily inclined.

Even after laying the panels, before inserting the cross joints, each panel corner can be corrected individually with eg a screwdriver down or up, without lifting the plates. At the star wheel each Plattenauflagers located on the base behind the corresponding spacer a row of teeth, formed by the Betätigungsfortsätze. With the tool introduced through the open joint to the row of teeth, the star wheel is turned by tilting, which lowers or raises the plate support with each rotation.

With very strong dynamic movements it can come in connection with different plate coverings to an emigration of the above-mentioned joint crosses. However, this represents an application-side, not negligible disadvantage.

From the foregoing, it is therefore an object of the invention to provide an advanced, reverse rotation safe height adjustable pedestal for offenfugig to be laid plates, which can be used without problems in all application situations and in the emigration of an inserted cross-seam is effectively prevented.

The object of the invention is achieved by the combination of features according to the teaching of claim 1, wherein the dependent claims represent at least expedient refinements and developments.

Accordingly, it is assumed that a reversible height adjustable pedestal for offenfugig to be laid plates, especially for paving slabs or other coverings freely weathered terraces, balconies or the like, comprising a base plate with a plurality of molded cylindrical bearing pedestals, each one a bearing base associated hollow cylindrical adapter with lateral actuation extensions to subjecting the respective intermediate piece of a twisting movement, cap-shaped pads, each having a support seated on an intermediate piece, the supports have a rotation and the height adjustment of coming into contact with the plate base pads via a thread mating between the bearing base, intermediate piece and an internal thread of the cap-shaped support , as well as with a joint cross.

According to the invention, the joint cross to the base plate directed locking surfaces, at the ends of at least one inlet slope is formed with laterally projecting barbs, wherein in the inserted state the barbs dig into the actuating projections.

Ausgestaltend the locking surfaces are formed as sections in the axial direction extending extensions of the joint cross surfaces.

First inlet slopes have a course in the direction of the joint cross center axis, wherein second inlet slopes have a deviating course therefrom.

The first and the second inlet slopes preferably have with their inclined surfaces to each other.

The barbs are present on each locking surface and have a protruding nose-like edge.

The respective nose has a straight surface, which is oriented substantially at right angles to an axial edge of the respective locking surface.

The invention will be explained below with reference to an embodiment and with the aid of figures.

Fig. 10

a sectional view of two adjustment positions of the support, wherein a locking screw is inserted into the journal of the cap-shaped support to avoid over-rotating.

In the reverse-rotation height-adjustable pedestal bearing according to the embodiment is initially based on a base plate 1, which several, e.g. has four molded cylindrical bearing base 2.

On the edge side, a plurality of guide bolts 3 extend upwards from the base plate 1 with a step-like shoulder 4 for later support of a joint cross 18.

Furthermore, starting from the surface of the base plate 1 extending vertically upwards as a reverse rotation several elastic pins or bolts 5 are provided.

In the plan view Fig. 1 It can be seen that in the interior of each bearing base 2 a Vielkantausnehmung 6, is provided in the example shown as a square.

In addition, the bearing pedestals have an external thread.

In the area of each bearing base 2, a recess 9 is provided on the base plate underside, which serves to receive an upper end of a support pin 7 of a shim 8 (see Fig. 5 and 6 ).

Furthermore, from the Fig. 1 recognizable that located in the respective bearing base 2 Vielkantausnehmung 6 extends in the base longitudinal direction and perpendicular to the base plate 1.

The hollow cylindrical spacer 10 after Fig. 2 has an external thread 11, for example, a left-hand thread, which is opposite to the internal thread 12, in this case a right-hand thread.

The thread inside the cap-shaped support 13 (see Fig. 3 ) is complementary to the external thread 11 of the hollow cylindrical intermediate piece 10 and constitutes a thread pairing.

Laterally from the intermediate piece 10 extend star-shaped actuating projections 14, which put the adapter 10 in rotation by applying a tool.

The cap-shaped support 13 with top closed roof surface and internal thread has a concentric pin 15 whose outer contour of the polygonal recess 6 in the bearing base 2, in the example shown corresponds to a square. In the pin 15, a cavity is formed, which is the Mounting of a threaded end of a locking screw 27 (see also Fig. 10 ) serves.

The length of the pin 15 is greater than the height of the cap-shaped support 13 such that the pin 15 and the Vielkantausnehmung 6 interlocking ensure the rotation of the cap-shaped support 13 even at their height adjustment.

Various positions of the height adjustment minimum / maximum can be found in the side view Fig. 4 open up, it can also be seen how the actuating projections 14 of the hollow cylindrical intermediate piece 10 are blocked by the elastic bolt 5 back-locking.

As a result of the recognizable curve in the end of a portion of the star wheel or gear as actuation extension 14 succeeds in performing a more vigorous movement, the respective pin 5, which has elastic properties, push out of its normal position, so that the height adjustment can be effected without another Tool for pushing away the bolt 5 is required.

The actuating extensions 14 extend as shown Fig. 2 from the lower edge of the hollow cylindrical intermediate piece 10 perpendicular to the cylinder longitudinal axis.

For further height compensation according to their representation according to Fig. 5 and 6 Shims 8 provided, which have surface-side dimensions, each of the base plate 1 (see Fig. 6 ) correspond.

The respective shims have a peripheral edge 16 of predetermined wall thickness and a plurality of trunnions 7, the position of which essentially corresponds to the bearing sockets 2 on the base plate 1 of the height-adjustable pedestal bearing.

The support pins 7 project beyond the edge 16 in terms of height and have such an outer contour which is complementary to the recess 9 in the base plate 1, to ensure a non-slip locking between shim 8 and the base plate 1 of the associated height-adjustable pedestal bearing.

Also, the shims 8 themselves have on their underside recesses 17 which are complementary to the arrangement of the support pin 7, to also achieve a non-slip locking several stacked shims 8.

The Fig. 7 shows a perspective view of the invention further developed joint cross 18th

The joint cross 18 has four joint cross surfaces 22, which are oriented crosswise to each other.

At the lower side in the direction of use the joint cross surfaces 22 are extended and go into each case a locking surface 19 via.

Again at the lower end of the respective locking surface 19 are first inlet slopes 20 and second inlet bevels 23. In addition, a barb 21 (see also Fig. 8 ) educated.

This barb 21 has a straight surface 25, which is oriented substantially perpendicular to the axial edge 26 of the respective locking surface 19.

The joint cross can be performed in a preferred manner as a plastic injection molded part and is therefore inexpensive to produce.

The width of the respective joint cross-surface 22 is adapted to the respective Fugenmaß to be observed.

Fig. 8 shows in a side view, the assignment of the joint cross 18 to the complete pedestal bearing, as shown in the Fig. 4 , Upper part of the picture, has already been shown and explained, so that reference may be made to the statements there.

In the illustration after Fig. 9 , which shows a perspective view of a terrace pedestal bearing, the position of the joint cross 18 was indicated by dashed lines after insertion into the pedestal.

In the end position of the joint cross 18 visible there, the lower edges of the respective joint cross surfaces 22 rest on the step-like shoulder 4 (see FIG Fig. 1 and 8th ). The respective barbs 21 engage under the respective actuating extension 14. By this measure it is ensured that the joint cross is securely fastened after installation and adjustment of the terrace slabs, whereby emigration of the joint crosses over the plate slab can be prevented. At the same time, the insertion of the joint cross 18 increases the reverse rotation safety of the pedestal bearings, since the intermediate pieces 10 can not rotate with the joint cross 18 inserted. This results in a particularly positive double function in the intended insertion of the joint cross 18th

The representation after Fig. 10 shows different positions of the support 13 using the opposite threads.

To avoid over-rotation of the support 13, a locking screw 27 is screwed into the cavity of the pin 15. In the illustration after Fig. 10 , Right part of the image, it can be seen how the screw head at maximum height position of the support 13 on the bearing base 2, and that on the inner surface of an upper edge of a local cavity comes to rest. Unscrewing or over-rotation of the support 13 is thereby safely and effectively prevented.
