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 bearing base or screwed onto this threaded piece, the approximately longitudinally an actuator in the form of a toothed on its periphery flange and has mutually opposite threads at both ends and having a corresponding thread, with respect to the base plate secured against rotation bearing piece for at least one of the laying 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 used individually with z. B. a screwdriver can be corrected down or up without lifting the plates. On the star wheel of each plate support is located on the base behind the corresponding spacer a row of teeth, formed by the Betätigungsfortsätze. With the tool inserted 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 DE 20 2004 005 765 U1 is also a height-adjustable plate storage for offenfugig to be laid floor panels previously known. For the spatial separation of several floor slabs, a joint cross or a joint tee is inserted from above between the floor slabs according to this solution.

From the foregoing, it is therefore an object of the invention, starting from the DE 298 19 317 U1 to specify a further developed, reversible, height-adjustable pedestal storage for offenfugig to be laid plates, which can be used without problems in all application situations and in which the emigration of a used cross-seam can be effectively prevented.

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

Accordingly, from a reverse-safe height adjustable pedestal for offenfugig to laying panels, in particular for pavement slabs or other coverings freely weathered terraces, balconies or the like, comprising a base plate with a plurality of molded cylindrical bearing pedestals, a respective bearing base associated hollow cylindrical intermediate piece with lateral actuation extensions to subject the respective intermediate piece of a twisting movement, cap-shaped pads , wherein in each case a support is seated on an intermediate piece, the supports have an anti-rotation and the height adjustment of the coming into contact with the plate base pads on a threaded 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.

Hereby show:

5 a side view and a plan view of a shim for a pedestal bearing;

6 a stacking arrangement of three shims and a pedestal in the use state;

7 a perspective view of the joint cross according to the invention;

8th a side view of the pedestal bearing with joint cross before pressing the same;

9 a perspective view of the pedestal bearing dashed lines indicated position of the joint cross, after this is pressed as a result of laying and adjustment of the terrace plates (not shown) in the corresponding cross joint, wherein the lateral actuating projections are moved to a position in which the barbs of the joint cross clawing in or under the actuating projections, whereby the migration of the joint crosses is prevented over the plate covering in the application; and

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-adjustable height adjustable pedestal bearing according to the embodiment is first of a base plate 1 assumed that several, z. B. four molded cylindrical bearing base 2 having.

Edge side extend from the base plate 1 upwards several guide pins 3 with step-like heel 4 for later edition of a joint cross 18 ,

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

In the plan view 1 It can be seen that inside each bearing pedestal 2 a polygonal recess 6 , In the example shown is provided as a square.

In addition, the bearing pedestals have an external thread.

In the area of each storage shelf 2 is still a return on the base plate underside 9 provided, the inclusion of an upper end a trunnion 7 a shim 8th serves (see 5 and 6 ).

Furthermore, from the 1 recognizable, that in the respective storage pedestal 2 located polygonal recess 6 in the base longitudinal direction and perpendicular to the base plate 1 runs.

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

The thread inside the cap-shaped pad 13 (please refer 3 ) is to external thread 11 of the hollow cylindrical intermediate piece 10 complementary and represents a thread pairing.

Laterally from the intermediate piece 10 extend star-shaped Betätigungsfortsätze 14 , Which by attaching a tool, the intermediate piece 10 put in rotation.

The cap-shaped pad 13 with top closed roof surface and internal thread has a concentric pin 15 , whose outer contour of the polygonal recess 6 in the warehouse socket 2 , in the example shown corresponds to a square. In the cone 15 a cavity is formed, which receives a threaded end of a locking screw 27 (see also 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 polygonal recess 6 interlocking the rotation of the cap-shaped support 13 also ensure their height adjustment.

Various positions of the height adjustment minimum / maximum can be found in the side view 4 it can also be seen how the actuation processes 14 of the hollow cylindrical intermediate piece 10 from the elastic bolt 5 back-locking be blocked.

Due to the recognizable rounding in the end region of a portion of the star wheel or gear as Betätigungsfortsatz 14 manages to perform a more vigorous movement, the respective bolt 5 , which has elastic properties, to 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 actuation extensions 14 extend as shown 2 from the lower edge of the hollow cylindrical intermediate piece 10 perpendicular to the cylinder axis.

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

The respective shims have a peripheral edge 16 with predetermined wall thickness and multiple trunnions 7 whose position is essentially the bearing pedestals 2 on the base plate 1 the height-adjustable pedestal corresponds.

The trunnions 7 tower over the edge in height 16 and have such an outer contour that the return 9 in the base plate 1 Complementary to a non-slip lock between shim 8th and the base plate 1 of the associated height-adjustable pedestal to ensure.

Also the shims 8th themselves have recesses on their underside 17 on, the arrangement of the trunnions 7 are also complementary to a non-slip locking several stacked shims 8th to reach.

The 7 shows a perspective view of the invention further developed joint cross 18 ,

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

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

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

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

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 joint size to be observed.

8th shows in a side view the assignment of the joint cross 18 to the complete pedestal, as it is in the 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 9 , which shows a perspective view of a terrace pedestal bearing, was dashed the position of the joint cross 18 indicated after insertion in the pedestal.

In the end position of the joint cross, which can be seen there 18 rest the lower edges of the respective Fugenkreuzflächen 22 on the staircase-like heel 4 (please refer 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 clawed after installation and adjustment of the terrace slabs, whereby emigration of the joint crosses over the plate covering can be prevented. At the same time increases the insertion of the joint cross 18 the reverse rotation safety of the pedestal bearing, since the intermediate pieces 10 with inserted joint cross 18 can not turn. This results in a particularly positive dual function in the intended insertion of the joint cross 18 ,

The representation after 10 shows different positions of the edition 13 using the opposite thread.

To overspeeding the edition 13 To avoid being in the cavity of the pin 15 a safety screw 27 screwed. In the illustration after 10 , right part of the image, can be seen as the screw head at maximum height position of the support 13 on the storage base 2 , And on the inner surface of an upper edge of a local cavity comes to rest. Unscrewing or over-rotating the pad 13 is thus safely and effectively prevented.
