Description

Height-adjustable support bearing

The invention relates to a height-adjustable support bearing for laying on a substrate floor covering elements with a height-adjustable trained body and with a variable on the body tiltably arranged support element.

Plate-shaped or strip-shaped flooring elements such as ceramic elements, stone slabs or

Wooden planks can be laid flat on a substrate side by side and form a substantially flat floor covering. Especially in outdoor areas outside of closed rooms, it may be appropriate for various reasons, the composite of the individual flooring elements flooring on a suitable

Supporting structure in an often small and only a few centimeters amounting distance above the ground

to arrange. From practice various support bearing constructions are known which are suitable for laying such

Flooring are suitable and commonly used. In many cases, there is the support structure for the flooring of a number of individual support bearings, which are usually placed at a regular distance from each other on the ground and on which the

individual flooring elements are laid. For one out Ceramic elements or stone slabs existing flooring the individual support bearings are expediently arranged in each case at the corners of the individual flooring elements, so that each floor covering element is supported by its corner regions. The support element is often formed sufficiently large area to accommodate four each with a corner adjacent flooring elements and to be able to support reliable above the ground. In many cases, the ground is not completely flat, so that by the support structure, the predetermined

Bumps should be compensated. For this purpose, height-adjustable support bearings are known from practice, having a height-adjustable designed base body and a bearing element arranged thereon. Around

To be able to compensate for unevenness or, for example, changing inclinations of the ground or around

For example, to be able to specify an advantageous for the drainage of the flooring slope of the flooring deviating from the ground, it is advantageous that the support element of such a support bearing is variably tiltable arranged on the base body, so that a support surface for a floor covering element not necessarily parallel to that of the Substrate predetermined

Contact surface of the support bearing must be aligned, but during the manufacture of the flooring arrangement can be inclined and aligned so that unwanted unevenness of the ground can be compensated and laid either a completely flat or oriented in a predetermined direction flooring. The well-known from practice height-adjustable support bearing with a pivotally mounted on a base body support element are by design consuming and expensive. In many cases, the maximum

Swivel angle of the support element very limited.

For a floor covering, which is located in an outdoor area and therefore the weather and possibly

Rainfall is almost inevitably penetrated by gaps and gaps between individual

Flooring Elements Moisture from the top of the flooring to the substrate. Although by the support structure of the floor covering is arranged at a distance to the ground and therefore by a

Ventilation of the floor covering a rapid dehumidification can be effected, accumulate moisture and water and in particular to those known from practice

Support bearings. Already small amounts of water on the

Supports cause a bearing in the support areas of the individual flooring elements on the support elements

unwanted moistening, especially in absorbent flooring materials moisture stains, and an associated discoloration or damage to the individual flooring elements.

It is therefore regarded as an object of the present invention, a height-adjustable support bearing of the type mentioned in such a way that with a

As small as possible constructive effort a simple and variable in a large angular range tilt or tilting of the support element is made possible. In addition, the support element should at least in the area a support surface for a flooring element so

be formed that from above penetrating moisture is not jammed or retained by the support element to an unwanted moisture penetration of the on

Support bearing resting flooring elements after

Possibility to reduce or avoid.

This object is achieved by a height-adjustable support bearing with a height-adjustable base body and with a variably tiltably arranged on the base support element, wherein the support element on an underside at least along an annular

Circumferential line partially spherical cap and concave bearing surface has, with which the support member is supported on the base body, wherein the support element on a top at least one

Having support surface for a flooring element, and wherein the top of the support element without lowering

is trained. Due to the design of the underside of the support element is largely independent of the

Shaping and design of the body a simple and possible over a wide range of angles variable

Tilt and appropriate orientation of the support element allows. About the spherical cap-shaped area of the underside of the support element is the

Supporting element in a predetermined position reliably and tilt-free supported on the body. The support element can be rotated almost arbitrarily relative to the base body, for example, a predetermined configuration of the top of the

Adjust support element to the arrangement and orientation of the overlying flooring elements. On the shape of the body in the area in which the support member is supported on the body, no restrictive requirements are made, which is why no complex, or costly design of the body is necessary. The main body may be in an end region facing the support element

For example, have three arranged in a triangle and upwardly projecting support posts. Of the

Base body may also have a tubular end portion having an annular end face on which the support member can be supported. Of the

Basic body can be a round or square base

exhibit. It is therefore possible to use a known from practice base body for the height-adjustable support bearing according to the invention, which is optionally provided for other support bearings and available. It is also possible to combine different support bearings in each case modularly and combined with a uniformly designed base body, so that the production costs for the

reduced support different bearings and storage can be simplified.

The main body may for example have two tubular body parts, wherein a first

Basic body part is arranged on a base plate and the second basic body part via a threaded portion with the first basic body part is engaged. By

Twisting of the second basic body part, the second basic body part along a directed perpendicular to the base plate adjusting axis relative to the first

Base body part and the base plate are relocated. One the base plate remote end portion of the second

Basic body part forms the bearing support surface on which the support element is supported. By a threaded engagement of the two basic body parts with each other can

stepless height adjustment possible. It is also conceivable that the basic body is an angular, for example rectangular or square

Has cross-sectional area and a stepped

Height adjustment is predetermined by several locking engagements of the two body parts together. In a given height adjustment of the main body

optionally be fixed with a locking device or the like in order to remove particularly high support loads can. Such embodiments of the body are known in different shapes and purposes of practice and can

optionally be used with the already known shape or an adapted shape for the height-adjustable support bearing according to the invention.

Due to the concave designed storage area at the

Bottom of the support element is a variable inclination of the support element not by the arrangement and

Dimensions of a formed on the top of the support element or arranged support surface for a

Flooring element limited and limited. Regardless of a maximum diameter, which has the concave bearing surface configured on the underside of the support element, the support surface formed on the upper side may have a substantially larger diameter and extend laterally far beyond the bearing surface of the support element formed on the underside. In order to avoid an undesirable accumulation of moisture in the region of the support element, it is provided according to the invention that the upper side of the support element is formed without a depression. In a depression, a concave depression surrounded on all sides by higher areas, could penetrate from above through the floor covering

Precipitation or moisture, optionally on or below the individual flooring elements

condenses, accumulates and build up. Due to the lower-free design of the top of the support element can be achieved without much effort that no

Fluid accumulation on the bearing surface of the

Form support element. The concave

Bottom of the support element supports and simplifies a lower-free design of the top of the

Support element. From above, for example, by joints or gaps between adjacent flooring elements

Penetrating liquid can flow unhindered over the

Drain the top of the support element sideways and drip onto the surface.

Since already the underside of the support element is at least partially concave, that can

Support element, for example, be thin-walled and hat-shaped, so that with a small

Cost of materials and low production costs over a wide range of inclination variable

Support element is made possible that also favors a rapid dehumidification of the support surface for a floor covering element. According to an advantageous embodiment of

The idea of the invention is that the

Support element on the bottom has a spherical cap and concave bearing surface. A not only annular, but over the entire bearing surface away kugelkalottenförmig and concave configured bearing surface allows a large angle of inclination for the supported on the body and variably tiltable

Auflagerelement and in almost all inclinations large-scale support of the support element on the

Basic body.

Preferably, it is provided that a diameter of a peripheral surface of the bearing surface of the support element greater than each diameter of a peripheral surface of the

Support element facing end portion of the body is. In this case, the peripheral surface is understood to mean a cross-sectional area or end face of the end region of the base body which faces the support element and is delimited by an outer circumferential line. For example, in a tubular embodiment of the end portion of the

Basic body having an annular, the support element facing end, the diameter of the bearing surface of the support element is greater than one

Outer diameter of the tubular end portion of the

Body. In order to provide a contact area of the largest possible surface area in different inclination positions of the support element and thereby large-scale support of the

Auflagerelements to allow on the body is provided that a diameter of the bearing surface of the

Auflagerelements more than once, 5 times, or more than twice the diameter of the end portion of the Base body amounts. The storage area is included

expediently also larger than a formed in the end region of the body bearing support surface on which the support member rests with the bearing surface. The storage area can, however, at a suitable

Design of the end portion of the body also have a significantly smaller diameter than the end portion of the body. One in many different inclinations or orientations particularly large area of contact between the

Auflagerelement and the main body can be made possible in a simple manner that the end of the

Basic body one at least along an annular

Circumferentially partially spherical cap and convex bearing support surface has. Compared to a ring-shaped end face of a

tubular and thin-walled body on which the support element can be supported, offers at least partially and optionally completely

spherical cap trained bearing support surface a much larger and larger-scale bearing support surface and allows reliable support of the on the

Support device arranged flooring and a reduced pressure load of the bearing surface.

According to an advantageous embodiment of

The idea of the invention is that the

Bearing element on the underside has an element towards the base projecting engagement element, which is in engagement with a recess of the base body and a losierhemmende connection of the support element with the Body causes. In this way it can be easily prevented during storage or during transport that the support element

unintentionally releases from the body after that

Support element has been connected to the base body so that the engagement element in the recess of the

Main body engages or engages behind an edge of the recess. The engagement element can be, for example, a mushroom-shaped formation or a latching tongue, which can each be inserted into a recess adapted thereto on the base body and can be secured behind, latching or positively locking on or in the recess. It is also possible according to the invention that the

Supporting element on the underside has an engagement element for projecting towards the main body with at least one spaced apart to the support element laterally projecting clamping tongue, so that an inwardly projecting

Section of the bearing support surface of the body can be clamped around. Due to the dimensions and

Design of the at least one clamping tongue can in

Dependence on the inwardly projecting portion of the bearing support surface a desired and intended

Clamping effect can be achieved. This way you can

be prevented from getting on during the hang up

individual flooring elements the support element

undesirable slightly twisted or tilted and difficult the laying of the flooring elements and their orientation to each other. The at least one clamping tongue can

For example, as a ring-shaped projecting clamping flange or be formed as a number of, for example, two, three or even more strip-shaped clamping tongues.

Alternatively or additionally, it is according to the invention

provided that the support element a

surface-structured bearing surface and / or the

Basic body has a surface-structured bearing support surface. The surface structuring can be produced for example by a subsequent roughening of the bearing surface and / or the bearing support surface. It is also conceivable and effective, the surface structuring by a number of protruding formations and / or

To create depressions of the surface in question, for example, by protruding teeth, fins or pyramids are formed. The surface structuring of the bearing surface and / or the bearing support surface can also undesirably rapid twisting or tilting of the

Support element are made difficult relative to the body.

In a similar way, the storage area

and / or the bearing support surface may be configured with an anti-slip surface or surface coating. Thus, for example, by a combination of a surface made of a soft material such as rubber and a surface formed of a comparatively harder material such as polypropylene or polyethylene, a sufficient anti-slip effect in the application of the support member on the body can be effected in many applications. It is also possible that at least one of the two

Surfaces an anti-slip coating, for example made of rubber or of a resilient polyurethane material.

According to an alternative embodiment of the

According to the invention, it is provided that the bearing surface and the bearing support surface each have a smooth surface and rest on one another without a gap. The

Shape of the bearing surface and the bearing support surface are suitably coordinated so that in the

Contact area between the bearing surface and the

Bearing support even with a pivoting of the

Storage area relative to the bearing support surface no gaps or cavities arise. In addition, the should

Surface roughness of the bearing surface and the bearing support surface should be as low as possible, which can be supported for example during or after manufacture by additional polishing of the bearing surface and the bearing support surface. It has been shown that the bearing surface designed in this way, in particular under load from resting

Floor covering elements can be twisted or pivoted only with a noticeable force, which, for example, adhesion forces and / or resulting between the bearing surface and the bearing support surface vacuum

can be returned.

In order to promote a discharge of moisture and water droplets on the upper side of the support element, it is provided that the upper side of the support element has a convexly curved abiauffläche, on the spaced apart at least one upwardly projecting

Floor support bearing is arranged. The one

Floor support bearing or spaced from each other arranged a plurality Bodenstützauflager each form a support surface for a floor covering element. The

Floor covering element concerned can either rest on a single Bodenstützauflager, or extend over several Bodenstützauflager and simultaneously rest on several Bodenstützauflagern. A

Contact surface of the one Bodenstützauflagers or more Bodenstützauflager may be just designed to form a planar bearing surface for a floor covering element. It is also possible and with a view to the fastest possible and effective dehumidification of a bearing area of the floor covering element on the

Support element advantageous in that on the top of the support element a plurality Bodenstützauflager are formed, each having a curved Bodenstützauflageroberseite. As a result, a floor covering element can be supported on the support bearing at several points simultaneously and thus particularly reliably and stably, without a large-area contact between the floor covering element and the support element favoring undesired penetration of the floor covering element into its support area.

A plurality of upwardly projecting Bodenstützauflager a support element can advantageously each a level arranged flat support surface for

Having flooring elements, so that the bearing surfaces of the Bodenstützauflager form a ground element support plane. Such a configuration of Bodenstützauflager

facilitates a level installation of each uniform floor elements on the floor element support plane, which is determined by the side by side or matrix-shaped support bearings. Unevenness of the underground can through a suitable height adjustment of the respective support bearing can be compensated. A given inclination of the

Flooring can be specified or made possible by a variably adjusted adjustment of the inclination of the individual support elements of the support bearings.

Advantageously, it is provided that the

Support surface of the at least one upwardly projecting Bodenstützauflagers at the top a center of the

Overlay element covered. It has proven to be advantageous that the individual flooring elements, which rest with a corner on the support element, as centrally as possible in the support element on the support surface

rest and be supported there. As a result, undesirably high tilting moments can be reduced, which rest and are supported by the center on the support element, so that undesired tilting during the assembly of the individual floor covering elements or during a use-related load of the

Flooring can be avoided.

It is preferably provided that on the upper side of the support element an impact sound insulating element is arranged. The insulating element can be a thin and

optionally disc-shaped support of a

Impact sound-absorbing material such as rubber, a soft plastic material or a soft

Polyurethane material exist. The insulating element can

permanently connected to the support element and

For example, as a coating or coating of the top of the support element or the support surface of the

Floor support bearing be formed. It is too possible and in terms of a cost effective and

simultaneously versatile customizable use advantageous that the insulating element is designed as a separate component, which can be placed on demand on the support element or on the Bodenstützauflager.

To the support according to the invention in an advantageous manner with different flooring types or

To be able to use flooring elements and their

To facilitate laying and alignment is provided that the support element has on its upper side a releasably connectable to the support element laying aid for flooring elements. The

Laying aid may be, for example, a joint cross, which, if necessary, on the top of the

Auflagerelements can be arranged and fixed. Depending on the size and type of laying of the individual plate-shaped flooring elements, for example

Ceramic tiles or Steinpatten, different sized and in particular different thickness joint crosses can be used and arranged on top of the support element. The laying aid can

For example, also have a clamping device for wooden strips, which are arranged in strip-like or lattice-shaped manner over a plurality of support bearings away to attach to it individual wooden planks.

To the for a separate production, assembly and assembly of a releasably connectable

Laying aid to avoid it is also possible and especially for plate-shaped

Flooring elements expedient that the support element at the top an upwardly projecting and

Having cross-trained like laying aid for plate-shaped flooring elements. The

Support element may also have a deviating configured laying aid that integrally

usually at the top of the support element

is trained. For different applications, differently designed support elements can each be combined with a uniformly designed base body and used.

To inexpensively a diverse use of the support element for different floor coverings or laying types of individual flooring elements on the

To allow support bearings is provided that the

Joint-like trained laying aid along a predetermined weakening line separable

Has disposable sections. If individual areas or the complete laying aid are not needed, the disposable sections can be along the given

Weakening lines are separated. Here are the

Preferably, weakening lines are arranged such that almost all sections of the laying aid are designed as disposable sections and as required

can be separated.

According to an advantageous embodiment of

The idea of the invention is that the

Support element at the bottom one down

Having projecting stop element, which in a lateral displacement of the support element on the

Body comes to rest and with which the lateral Displacement of the support element is limited. It is basically possible that the engagement element

simultaneously forms the stop element. The

However, stop element does not have to be in a losierhemmenden or captive engagement with the body, but only prevent excessive lateral displacement of the support member relative to the body to avoid that the support element is displaced too much laterally and not sufficient on the

Base is supported, so that the support element could accidentally fall off the body. The stop element may be a downwardly projecting formation. The molding may for example be arranged centrally or annular.

Below, by way of example, some embodiments are explained in more detail, which are illustrated in the drawing. 1 shows a perspective view of a support device according to the invention,

Insulating element is arranged.

A support bearing 1 shown in FIGS. 1 and 2 has a base body 2 and a support body 2 on the base body. 2

stored support element 3. The main body 2 has a first main body part 4, which is tubular and formed with an internal thread 5 and on a

Base plate 6 of the base body 2 is fixed. In the first basic body part 4 is a second, in a lower region also tubular shaped

Basic body part 7 is arranged. The second main body part 7 has on an outer circumferential surface 8 an external thread 9, which is adapted to the internal thread 5 of the first basic body part 4 and is in engagement therewith. By a rotation of the second basic body part 7 relative to the first basic body part 4 and the base plate 6 is the second basic body part 7 is displaced along a direction perpendicular to the base plate adjusting axis 10 relative to the first base body part 4 and the base plate 6, whereby a height adjustment can be effected.

The second main body part 7 has on a base plate 6 facing away from the end portion 11 on a spherical cap and convex bearing support surface 12. On the second basic body part 7 or on this bearing support surface 12, the support element 3 is arranged. The

Support element 3 has on its underside 13 a likewise spherical cap-shaped and concave bearing surface 14, the shape of which on the

Bearing support surface 12 of the base body part 7 is adapted, that the support member 3 is displaced on the bearing support surface 12 and thereby can be inclined relative to the base body part 7 and the adjustment axis 10 and the base plate 6. The maximum angle of inclination or angle range for the variable inclination is not by lateral

Strokes given, but essentially given only by the dimensions of the support element 3 and in particular the bearing surface 14 of the support element 3.

The support element 3 has a base plate 6 facing away from the top 15, which is also formed kugelkalottenförmig and convex over wide areas. At the

Top 15 are upwardly projecting

Bottom support support 16 is formed, which is a flat

Have support surface 17, on which a

Flooring element can be placed and supported.

The bearing surfaces 17 of the plurality of Bodenstützauflager 16 are each arranged at the same level and aligned so that the bearing surfaces 17 a flat

Form bottom element support plane, which is supported as a support surface for the support bearing 1 on this

Flooring elements is used. The shape of the top 15 of the support member 3 is not only in the

spherical cap-shaped surface area, but also formed at the Bodenstützauflagern and the respective edge and transition areas without lowering, so that from the top of the top 15 passing moisture or liquid is not collected or retained, but can run off to the side.

On the upper side 15 of the support element 3, an upwardly projecting joint cross 18 is formed, which serves as a laying aid 19 and the arrangement and orientation of up to four each supported with a corner on this support bearing 1 floor covering elements

facilitated . In an exemplary embodiment of the support element 3 shown by way of example in FIGS. 3 and 4, a larger number of bottom support supports 16 are formed on its upper side 15 whose support surface 17 is smaller than in the exemplary embodiment shown in FIGS. 1 and 2. About the multiple small Bodenstützauflager 16 can also be a reliable and stable support of each resting flooring elements. In addition, compared to a single entire area

trained Bodenstützauflager or compared to a few large Bodenstützauflagern the

Contact area, the entirety of the individual

Bodenstützauflagern 16 formed bearing surfaces 17, be reduced and thereby an effective and effective dehumidification of the resting

Flooring elements in this area are favored. On the underside 13, the support element 3 has a mushroom-shaped and downwardly projecting engagement element 20. The engagement element 20 of the

Supporting element 3 is formed with a recess 21 in the spherical cap over a wide areas

End portion 11 of the second basic body part 7 in engagement, so that a loss-inhibiting effect is generated. The recess 21 is dimensioned such that the mushroom-shaped

Engagement element 20 can be introduced, but not readily unintentionally can escape from the recess 21. Around the recess 21 around is the

End portion 11 of the second basic body part 7 along a circumferential line partially formed kugelkalottenförmig.

5 and 6 an exemplary embodiment of a support element 3 is shown by way of example, in which the laying aid 19 is produced separately and detachably connected to the support element 3. For this purpose, a laying auxiliary attachment 22 is arranged on the upper side 15 of the support element 3 and laterally through

projecting stop elements 23 held in its predetermined position. The stop elements 23 can also be used as latching elements or latching tongues

be trained and laterally embrace the laying aid attachment 22. The laying aid attachment 22 has an upwardly projecting joint cross 18. It is possible to various ^¬ dene auxiliary laying essays 22 different

dimensioned joints cross 18 produce and depending on Use and flooring with uniform

produced support elements 3 and 2 basic bodies to combine. In the illustrated in Figs. 1 to 6

Embodiments are the bearing surface 14 and the

Bearing support surface 12 each formed smooth and

designed with respect to their shape so that the bearing surface 14 rests gap-free on the bearing support surface 12. For this purpose, the bearing surface 14 and the bearing support surface 12 have the same surface curvature.

Favored by adhesion forces and a join in

Load of the support element 3 by resting

Floor covering elements optionally forming negative pressure between the bearing surface 14 and the bearing support surface 12 is thereby an undesirable twisting or tilting of the support element 3 is hindered relative to the base body 2 and difficult. This slip-inhibiting and tilting obstructing effect can be promoted by the largest possible configuration of a contact surface area in which the bearing surface 14 of the support element 3 rests on the bearing support surface 12 of the second basic body part 7. In FIGS. 7 to 10 differently configured support elements 3 are shown, each on a

Base body 2 are arranged, which also deviates from the basic body 2 shown in FIGS. 1 and 2

is designed. The support element 3 shown by way of example in FIG. 7 has a substantially planar upper side 15. On the upper side 15 of several lining support ^¬ devices 16 are arranged each having a flat and level equal arranged support surface 17th The underside 13 of the support element 3 is almost completely spherical dome-shaped and concave. In a central region of the underside 13, a downwardly projecting stop element 24 is formed, which is a lateral

Displacement of the support member 3 relative to the second basic body part 7 and a concomitant inclination of the support member 3 relative to the base plate 6 limited. By the stop element 24 can be prevented in a simple manner that the support element 3 is laterally displaced so far beyond the base body 2 during assembly and the erection of the flooring arrangement that the support element 3 is no longer sufficiently supported on the base body 2 and can fall down , The second basic body part 7 has, in the upper end region 11, an annular end face 25, which forms the bearing support surface 12. The bearing support surface 12 is also formed along a circumferential line partially spherical dome-shaped. The bearing support surface 12 may also have a different shape and Example ^¬ conically be flat or rounded.

In Figs. 8, 9 and 10 are exemplified respectively

differently configured support elements 3 with

differently shaped stop elements 24

shown. FIG. 11 shows, by way of example, a sectional view of a bearing element 3 designed differently, which has a surface-structured bearing surface 14. Distributed over the bearing surface 14 is a large number of small protruding formations 25 regularly or irregularly distributed. The bearing support surface 12 of the base body 2 is formed surface-structured and also has a large number of projecting

Formations 26 on. Once a floor covering element is placed on the support surface 17 on the upper side 15 of the support element 3, the load is due to the

surface-structured bearing surface 14 is pressed onto the likewise surface-structured bearing support surface 12 and due to the positive connection between the individual

projecting formations 25, 26 prevents twisting or lateral tilting of the support element 3 relative to the base body 2.

FIG. 12 shows a sectional view of a support element 3, which again has a different design, and which has an engagement element 27 projecting downwards in FIG. 12 with a radially projecting, flange-shaped clamping tongue 28. The engagement element 27 and in particular the arrangement and configuration of the clamping tongue 28 are in such a way to the inwardly projecting portions 29 of the second

Base body part 7 adapted in the region of the bearing support surface 12 that the end portions of the inwardly projecting portions 29 are clamped between the clamping tongue 28 and the inner region of the bearing surface 14 and thereby undesirable twisting or tilting of the

Supporting element 3 relative to the second basic body part 7 and to the main body 2 is difficult. An additional example is shown in FIGS. 13 and 14

Sectional view of a support element 3 with a

shown cross-trained like laying aid 19. The laying aid 19 has a

Joint cross 18, which is formed by four strip-shaped webs or tongues, which protrude substantially perpendicularly from the surface 15 of the support element 3.

Each individual web or strip of the joint cross 18 has immediately adjacent to the surface 15 of the

Support element 3 a predetermined by a constriction weakening line 30. The separated by the lines of weakness 30 of the surface 15 of the support member 3 sections form disposable sections 31, which can be easily separated as needed along the respective weakening line 30 of the support element 3. In this way, the support element 3 can be manufactured inexpensively uniformly in large quantities and depending on the intended use with or without one

Laying aid 19 can be used.

FIGS. 15 and 16 each show a plan view of differently configured support elements 3
