Description

The The invention relates to a non-reversible height adjustable Pedestal for offenfugig to be laid plates, in particular for pavement slabs or other coverings freely weathered Terraces, balconies or the like comprising a base plate with several molded, cylindrical bearing pedestals, a hollow-cylindrical intermediate piece assigned in each case to a bearing pedestal with side actuation extensions to the respective To subject intermediate piece of a twisting motion, cap-shaped Editions, each with a support on an intermediate piece seated, the pads have a rotation and the height adjustment of the with the plate underside coming in contact pads over a thread pairing between bearing base, intermediate piece and an internal thread of the cap-shaped pad, 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 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 in addition upstanding, flexible locking pins are present, which engage in the toothing of the actuator to effect a reverse rotation of the threaded piece, so that an unwanted lowering of the bearing piece can be prevented. In addition, 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.

Around Accordingly, to prevent the Auflagerstück at a Mitdrehung, this has a fork-shaped radial approach over a standing on the base plate rigid guide pin attacks. Due to the necessity of the radial approach to the rotation results in a corresponding space requirement, since the locking pin radially spaced outside the pivoting range of the actuator is to be arranged on the base plate. In addition to this space problem follows an increased cost of materials usually from a pedestal made of plastic injection molding material, which cost is disadvantageous.

The Base plate of the aforementioned Stelzlagers is unstructured, which leads to problems then if there is a need the pedestal with plates, z. B. of extruded polystyrene inferior. Here there is a risk of slipping and an uncertain Overall design.

Out The above, it is therefore an object of the invention, an evolved reversible, height-adjustable pedestal for indicate open plates to be laid, which in all application situations can be used without problems and that over a effective anti-rotation device for the pads, which with The plate undersides come in contact. By Elimination of previously necessary radial neck parts for the purpose of anti-rotation should facilitate accessibility of the actuating extensions for subsequent height adjustment already relocated Plates become possible. Furthermore, it is an object of the invention to make the height adjustment over-twist-proof.

The Solution of the object of the invention is achieved by the feature combination according to the teaching of claim 1, wherein the Subclaims at least expedient Represent refinements and developments.

Therefore is height-adjustable from a non-reversible Pedestal for offenfugig to be laid plates, in particular for pavement slabs or other coverings freely weathered Terraces, balconies or the like started, comprising a base plate with several molded, cylindrical bearing pedestals, a hollow-cylindrical intermediate piece assigned in each case to a bearing pedestal with lateral actuation extensions to the respective intermediate piece subject to a twisting movement, cap-shaped pads, wherein in each case a support is seated on an intermediate piece, the pads have a rotation and the height adjustment the with the underside of the plate in contact coming over a thread pairing between bearing base, intermediate piece and an internal thread of the cap-shaped support takes place.

According to the invention in the respective bearing base a Vielkantausnehmung, z. B. in shape a square, located in the base longitudinal direction and runs perpendicular to the base plate. Ausgestaltend is the Bearing base a hollow structure and from the base plate base can an over-rotation protection are introduced.

B. the mentioned square, corresponds and wherein the pin a length greater than the height having the cap-shaped support, such that the Pin and the Vielkantausnehmung interlocking the rotation form the cap-shaped pad. In other words, can Although the edition will be adjusted in height, however, will on co-rotation by the leadership of the pin in the Vielkantausnehmung prevented. The pin is in one embodiment, a bore or a blind hole introduced to the over-rotation, z. B. in the form of a self-tapping screw. The Screw is inserted from the base plate underside into the bearing base, wherein the screw thread penetrates the Vielkantausnehmung and engages in the blind hole. The screw head is at maximum extended, d. H. maximum height position of the support on the base plate Directed lower side of the Vielkantausnehmung and prevents another height adjustment or overspeeding.

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

Farther the hollow cylindrical intermediate piece has an external thread, opposite to the internal thread, the thread in Inside the cap-shaped support to the external thread of the hollow cylindrical intermediate piece complementary is and forms a thread pairing. Thus, at a low Height achieved a maximum height adjustment become.

In a preferred embodiment of the invention is the Bearing base rotatably performed with the base plate or connected to this, z. B. in one piece by an injection molding process manufactured.

The Actuar processes are sternrad- or gear-shaped formed and extend substantially perpendicular to the intermediate piece longitudinal axis, from above with a tool engaging the necessary twisting movement to effect for the purpose of height adjustment.

Each Intermediate piece and the local actuating extensions is associated with a known reverse rotation.

The Reversing protection is preferred as a from the base plate each extending, elastic pin or bolt executed.

The Sternrad- or gear-shaped Betätigungsfortsätze have at their outer edges a z. B. circular arc Rounding, under increased operating effort temporarily push out the elastic pins or bolts from their locking position, but without their desired effect as reverse rotation to endanger.

By the rounding at the outer edges of the Betätigungsfortsätze manages, despite active reverse rotation with the explained higher force a height adjustment by Achieving execution of the twisting movement, with over the detent sound of the pin or bolt relative to the Gear part of the actuating extension quasi the adjustment counted and thus clearly 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, d. H. these close in height with the cylinder lower edge.

at a preferred embodiment are for further height compensation stackable shims provided which have dimensions, each corresponding to the base plate of the outer contour ago.

The Shims have a peripheral edge and trunnion, whose arrangement corresponds to that of the bearing base to corresponding To absorb forces on the load side.

2 Sectional view, side view and top view of a hollow cylindrical intermediate piece;

3 Sectional view, side view and top view of a cap-shaped support with pin;

4 a side view of a complete pedestal bearing with different height position of the support;

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 various representations of the edition with pin and blind hole and

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

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.

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.

About that 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, which is the inclusion of an upper end of a trunnion 7 a shim 8th serves (see 5 and 6 ).

Furthermore, from the 1 recognizable that in each bearing base 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.

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.

Different positions of the heights minimal / maximum can be seen 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.

With the help of 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 pad 13 also owns a pin here 15 in the form of a polygon, in the example shown in the form of a square.

This pin 15 however, has a blind hole 18 on, which is capable of an over-rotation, z. B. in the form of a threaded end of a self-tapping screw 19 (please refer 8th ).

This screw 19 becomes, as from the sectional views 8th removable, from below through the base plate 1 in the designed as a hollow body bearing base 2 introduced. The thread of the screw 19 is dimensioned so that it by the Vielkantausnehmung in the bearing base 2 passes through and into the blind hole 18 of the pin 15 can be screwed.

The head of the screw 19 can be in the cavity 20 of the storage pedestal 2 , unhindered following the height adjustment up and down, move, however, is so dimensioned that at maximum height adjustment takes place an Inkontaktkommen 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 this may be from the intermediate piece 10 replaces or the intermediate piece 10 from the thread of the bearing pedestal 2 is turned off.

For assembly or disassembly purposes is the screw 19 over the cavity 20 slightly from the bottom of the base plate 1 accessible.

It lies within the meaning of the invention, that instead of in the figurative Depictions recognizable self-tapping screw also a rivet, a bolt or the like may find application.
