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 with a support seated on an intermediate piece, the editions have a rotation and the height adjustment of coming into contact with the plate bottom pads via a threaded mating between the bearing base, intermediate piece and an internal thread of the cap-shaped support takes place, according to the preamble of 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 previously known. This known bearing is based on a base plate which carries at least one threaded bearing base, one with an end in the bearing base or screwed onto this threaded piece, the approximately longitudinally an actuator in the form of a toothing at its periphery Having a flange and at both ends to each other opposite threads 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 standing, flexible locking pins are present, which engage in the toothing of the actuating member to effect a reverse rotation of the threaded part, so that an unwanted lowering of the bearing piece can be prevented. In addition, the cited teaching discloses an embodiment, according to which the locking pin with a on the base plate arranged guide pin can be identical, which passes through the same in a conventional manner to prevent rotation of the respective Auflagerstücks by a recess in a radial approach.

Accordingly, in order to prevent the bearing piece from rotating, it has a fork-shaped radial projection which engages over a rigid guide pin arranged on the base plate. Due to the necessity of the radial approach to prevent rotation results in a corresponding space requirement, since the locking pin radially spaced outside the pivoting region of the actuator is to be arranged on the base plate. In addition to this space problem follows an increased cost of materials usually made of a plastic injection molding material Stelzlagers, which is cost-side of disadvantage.

The base plate of the aforementioned pedestal bearing is unstructured, which leads to problems when there is a need, the pedestal bearings with plates, e.g. made of extruded polystyrene. Here there is a risk of slipping and an unsafe overall design.

From the foregoing, it is therefore an object of the invention to provide a weiterent-wrapped reverse rotation safe height adjustable pedestal for offenfugig to be laid plates, which can be used without problems in all situations and the use of an effective anti-rotation device for the pads, which come into contact with the undersides of plates features. By eliminating the previously necessary radial neck parts for the purpose of anti-rotation easier accessibility of the actuating projections for subsequent height adjustment already laid panels should be possible. Furthermore, it is an object of the invention to form the height adjustment over-rotating.

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, from a reverse-safe height adjustable pedestal for offenfugig plates to be laid, in particular for paving slabs or other coverings of 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, kappenför-shaped pads, each with 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 threaded mating between the bearing base, intermediate piece and an internal thread of the cap-shaped support.

According to the invention in the respective bearing base a Vielkantausnehmung, e.g. in the form of a square, located in the longitudinal direction of the base and perpendicular to the base plate. Ausgestaltend the bearing base is a hollow structure and from the base plate underside an over-rotation protection can be introduced.

The respective cap-shaped support has a concentric, ie extending in the cap longitudinal direction pin whose outer contour of the polygonal recess in the bearing base, for example, the mentioned square corresponds, and wherein the pin has a length greater than the height of the cap-shaped support, such that the pin and the Vielkantausnehmung meshing form the rotation of the cap-shaped support. In other words, although the support can be adjusted in height, but is prevented from turning by the leadership of the pin in the polygonal recess. In the journal in one embodiment, a bore or a blind hole is introduced to accommodate the over-rotation, for example in the form of a self-tapping screw. The screw is inserted from the base plate underside in the bearing base, wherein the screw thread penetrates the Vielkantausnehmung and engages in the blind hole. The screw head is at maximum extended, ie maximum height position of the support to the base plate directed lower side of the polygonal recess and prevents further height adjustment or overspeeding.

Furthermore, according to the invention, the respective bearing pedestal has an external thread, which is complementary to an internal thread of the associated hollow cylindrical intermediate piece.

Furthermore, the hollow cylindrical intermediate piece has an external thread, opposite to the internal thread, wherein the thread in the interior of the cap-shaped support to the external thread of the hollow cylindrical intermediate piece is complementary and forms a thread pairing. Thus, a maximum height adjustment can be achieved with a low height.

In a preferred embodiment of the invention, the bearing pedestal is rotationally fixed to or connected to the base plate, e.g. manufactured in one piece by an injection molding process.

The actuating projections are formed sternrad- or gear-shaped and extend substantially perpendicular to the intermediate piece longitudinal axis in order to effect from above with a tool engaging the necessary rotational movement for the purpose of height adjustment.

Each adapter and the local actuation extensions is associated with a known reverse rotation.

The reverse rotation lock is preferably designed as an extending from the base plate respectively, elastic pin or bolt.

The star-wheel or gear-shaped actuating extensions have, at their outer edges, e.g. circular arc-shaped rounding to temporarily push out the elastic pins or bolts from their locking position under increased operating force, but without jeopardizing their desired effect as reverse lock.

Due to the rounding at the outer edges of the Betätigungsfortsätze manages despite active reverse rotation with the explained higher force to achieve a height adjustment by performing the rotational movement, wherein on the detent noise of the pin or pin relative to the gear part of the actuating extension quasi the Verstellbetrag counted and thus in a clear way without measuring tools can be determined.

The actuating extensions extend from the lower edge of the hollow-cylindrical intermediate piece perpendicular to the cylinder axis, i. these close in height with the lower edge of the cylinder.

In a preferred embodiment, stackable shims are provided for further height compensation, which have dimensions which correspond in each case to the base plate from the outer contour.

The shims have a peripheral edge and trunnions whose arrangement corresponds to that of the bearing base in order to absorb corresponding forces on the load side.

Furthermore, the support pins protrude above the circumferential edge of the shims in terms of height and have such an outer contour which is complementary to a respective recess of the base plate to ensure a non-slip locking between shim and base plate of the pedestal. For this purpose, engage the tops of the trunnions in the aforementioned recess or the recess in the base plate underside.

The shims also have underside recesses which are complementary to the arrangement of the support pins in order to achieve a non-slip locking of a plurality of stacked shims.

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. By the reverse rotation, for example, up to 22 mm individually infinitely height-adjustable plate supports tolerances in the plate thickness and in the base are also compensated, so that the surface of the lining is flat and steadily inclined.

Also, after laying the panels, before inserting the joint crosses, each panel corner can be sealed individually with e.g. a screw carrier up or down corrected 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 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.

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

Hereby show:

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

Fig. 7 various representations of the edition with pin and blind hole and

Fig. 8 Representations of the overall arrangement and sectional views of the over-rotation protection.

In the non-reversible height adjustable pedestal bearing according to the embodiment example, it is initially assumed that a base plate 1, which several, eg four molded cylindrical bearing base. 2 having.

On the edge extend from the base plate 1 up several guide pins 3 with staircase-like paragraph 4 for later edition of a joint cross.

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 inside each bearing base 2 a polygonal recess 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.

Extending laterally from the intermediate piece 10 are star-shaped actuating extensions 14, which set the intermediate piece 10 in rotation by attaching 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.

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 inein other cross 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 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 pedestals 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, in order 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.

With the help of Fig. 7 and 8th let the over-rotation protection according to the invention, which prevents the exceeding of a maximum height adjustment, explained in more detail.

The cap-shaped support 13 also here has a pin 15 in the form of a polygon, in the example shown in the form of a square.

However, this pin 15 has a blind hole 18 which is capable of over-rotation protection, for example in the form of a threaded end of a self-tapping screw 19 (see Fig. 8 ).

This screw 19, as shown in the sectional views Fig. 8 removed, introduced from below through the base plate 1 in the bearing block 2 designed as a hollow body. The thread of the screw 19 is dimensioned such that it passes through the polygonal recess in the bearing base 2 and can be screwed into the blind hole 18 of the journal 15.

The head of the screw 19 can move in the cavity 20 of the bearing base 2, unhindered following the height adjustment up and down, but is dimensioned so that at maximum height adjustment takes place in contact with the bottom of Vielkantausnehmung.

Accordingly, this contacting the screw head with the underside of the polygonal recess prevents further unscrewing of the support, so that it may detach itself from the intermediate piece 10 or else the intermediate piece 10 is turned off by the thread of the bearing base 2.

For assembly or disassembly purposes, the screw 19 is easily accessible via the cavity 20 from the underside of the base plate 1.

It is within the meaning of the invention that instead of recognizable in the figurative representations self-tapping screw and a rivet, a bolt or the like can find application.
