Description

The present invention relates to a support board, as it is commonly used in the sanitary area when putting a bath, shower or whirlpool.

Such a support board primarily fulfills the function of carrying the tub and distributes the pressure of the tub feet or support surface on an underlying raw, subfloor or screed.

The requirements for such a support board are varied and high in terms of strength, stability, height, ease of installation of the tub, but also in terms of tightness or penetration of moisture and sound insulation.

The object of the present invention is to provide a support board optimized for the stated requirements for the stated purposes.

The solution to the problem consists initially in the design and refinement of at least one at least single-layer plate on which at least two level adjustments are arranged.

An inventive level control of a support board according to the invention comprises in its simplest form an upside-down screw which is arranged from below in an approximately vertical bore in the plate or in a frame which holds the plate or plates. This bore may have a drive nut or a threaded sleeve and thus results in a regulation of the level of the support board solely by rotations of the screw. For the purpose of sound decoupling, a sound-decoupling material is preferably provided at the head of the screw arranged, at least at the top of the head, which in the present case footprint.

The screw can be rotated, for example, by attaching a spanner or wrench on her screw head. However, this may prove to be difficult or impossible in certain installation situations and therefore at the opposite end of the screw preferably a slot for receiving a screwdriver or another key holder is formed, be it in the form of an external, hexagon or Torx profile. This end of the screw remains operable within a bore through the plate or protrudes beyond the surface of the plate.

Instead of a screw, only a threaded rod can be used, but then necessarily with a key holder in the form described or at least one section, which is preferably four- or hexagonal.

An improved sound decoupling, but also an improved and positionally true setting of an inventive carrier board by means of a level control, which preferably provides a sound-decoupling socket. Further preferably, this base stops when you operate the level control and does not rotate with you. This can be realized by the level control comprises a ball joint, with a ball, which can be pressed by overcoming a force in a positive socket and thus remains assembled and disassembled in this way. Instead of a ball, every imaginable geometric body with a round circumference comes into consideration, ie every rotation body and a corresponding rotation body pan.

The base, which preferably does not rotate, doing this already due to the friction, in addition to the base on its underside, however, also have an adhesive surface and / or holes through which a screw fixing it is screwed into a dowel.

Instead of a ball joint, however, it is also possible to equip the base with such a long threaded socket for a threaded rod, so that it results in a sufficient adjustment range. However, this design variant has the disadvantage that it builds higher than that with the ball joint. A low height can be an important criterion, especially in the realization of disabled showers.

The base of both embodiments preferably consists of sound-insulating material itself or at least has such a layer on the underside.

A further embodiment variant of a level control according to the invention, which is a component of a carrier board according to the invention and thus provides a further embodiment variant of the latter, likewise offers stepless regulation at any desired level and the advantage that it also functions with the bowl attached if required. This is realized by the level control is spring-resistant with at least one spring, preferably with such a spring force, which keeps the weight of the supporting board plus the weight of the attached pan quasi "in balance", that is carried within the stroke of the springs.

Furthermore, this embodiment variant of a support board according to the invention has a locking device for the spring force. In this way, a precise setting directly the tub is possible, and not just the support board on a determined, previously determined intermediate measure. The regulation of the level is carried out by pressing or lifting the tub to the required final size and subsequent actuation of the lock, which is preferably simultaneously operated centrally for all level adjustments or to several level adjustments simultaneously and preferably only from one side of the support board. This eliminates not only the setting of the support board on the previously determined intermediate measure, but also the single operation of possibly inaccessible level adjustments.

The locking device can for example be realized by gears engage in rack-shaped flanks of the foot and thus rotate with an up or down movement of the support board. Now, if the rotation of this gear is locked, so the support board remains at this level. The locking of the gear can be done by being supported by means of an example square axle bore on an axis having a first portion with a round cross-section and a second portion with also quadrangular cross-section. By a longitudinal displacement of the axis, the quadrangular cross section of the axis can engage in the quadrangular axle bore of the gear and lock it so. Alternatively, however, the axle may also be fixedly connected to the toothed wheel and locked, for example, by means of a splint or a claw.

A further embodiment variant of a carrier board according to the invention also provides a central or multiple barrier for the level adjustments, but in these no springs, but balloons or bellows, which are inflated by means of air pressure. They are preferably arranged in a housing which is open at the top and raise or lower the support board to the desired level - with or without patch trough - and then the support board is locked on this. It is basically possible first to align the support board horizontally or in a desired slope and then to operate all level adjustments simultaneously by means of a pump or a compressor, or to provide a single control of each level control.

Basically, however, a level control with balloons or bellows or springs is possible even without lock by simply padded or filled after reaching the desired level of the space between the support board and bare floor.

A further embodiment variant of a support board according to the invention comprises level adjustments which function by means of at least one eccentric disc. By rotating the eccentric disc, be it with a key in a corresponding key receptacle, or by means of an axle on which they are mounted, the desired level of the support board can be adjusted. Subsequently, the support board is lined or filled the underlying space or the eccentric discs are also locked with one of the above disclosed locks.

It is conceivable to combine the described level adjustments with each other. Thus, a level control according to the invention can have both a spring and a bellows or balloon, as well as gears and eccentric discs.

A further embodiment variant of a carrier board according to the invention provides a position adjustment for the level adjustments, preferably within a guide rail. This guide rail can be linear or else arcuate and be arranged on, in or on the support board plate. With position adjustment is meant that the level adjustments not only are adjustable in height and thus can regulate the level of the support board, but are also adjustable in a plane that corresponds approximately to the plane of the support board or its plate or its plates. This has the advantage that the level adjustments or the feet of the support board can be positioned within the adjustment as needed, depending on the installation situation or depending on the nature or unevenness of the subfloor, for example.

The plate, which is also part of a carrier board according to the invention, can be a single plate, but also a multilayer sandwich construction, also of different materials. For this purpose, solid wood, laminated wood or pressed chipboard, but also metal, plastic, fiber laminates and concrete come into consideration.

It is possible to place several support boards on top of each other as needed or in specific installation situations.

The plate or plates of a support board according to the invention preferably have holes and / or recesses and / or slots, for the arrangement or accessibility to processes, water and / or power lines, but also for accessibility to the level adjustments or for the possibility to subsequently use a level control.

On the plate or the plates of a carrier board according to the invention optionally so-called shuttering aids can be provided. These are basically other plates or panels that are pre-assembled for example by means of appropriate profiles or mounted on site and give the approximately horizontal surface of the support board for this purpose approximately vertical support surface on which a side wall of the tub can be built or poured.

Furthermore, a support board according to the invention preferably has lateral adjustable stabilizers by means of which a set support board can be braced or stabilized on the lateral connection walls and / or on the floor.

An inventive support board or its plate is preferably lined at least at the edges with sealing and / or Schallentkopplungsbändern. This not only a desirably dense substructure for a tub is possible, but also a further optimized sound insulation, because the sealing tapes themselves are usually made of insulating foam.

Soundproofing materials, which may be incorporated into the material of the plate or placed, glued, affixed or potted on or under the plate or between the layers of the plate, also serve as an optimized sound insulation.

An inventive support board can be the same size as the tub, but also smaller or larger and optionally have the rounding of the tub also, but also an asymmetric shape for this purpose.

Especially with large tubs, a support board is advantageous, which is formed from two or more parts. For this purpose, flat, L, C, I or T profiles may be provided, by means of which the parts are connectable, preferably made of metal. Such profiles can be provided as stiffeners even with one-piece support boards. Further connection possibilities of several parts result from positively overlapping edges or groove-and-comb arrangements.

Furthermore, so-called tray supports and / or setting elements can be preassembled on a support board according to the invention or in appropriate fixings on site be mounted, positive insertion, glued or welded. Such tub support or setting elements are usually U-shaped profiles, preferably sound-insulated, which correspond to the bulge of the tub cross-section. The tub support or setting elements may have corresponding recesses or recesses in which find protruding parts of the level adjustments. The same applies to mounting systems that include tub supports and / or setting elements and a mounting frame, which is common in setting a loose tub.

Filling plates can also be pre-assembled or mounted on site in appropriate holders or holders. In principle, a gradient can be generated with the leveling of the support board, but it may prove in certain installation situations easier to put the support board "into the water" and readily measuring and testing by placing and attaching the slope plate directly to the desired slope to get. This precipitation plates can be designed in one piece or in several parts.

In the Fig. 1 a first embodiment variant of a support board 100 according to the invention is shown schematically and in perspective in the assembled, but not mounted or installed state. The support board 100 has a plate 1, at the corners of each a level control 200a-200d is arranged. The level controls 200a-200d are preferably mounted in arcuate guides 2a-2d, which preferably at the bottom of the support board 100 not shown in detail, also arcuate guide rails. In this way, the level adjustments 200a-200d are adjustable in their position, in a plane E which corresponds approximately to a surface plane OE of the plate 1.

The level controls 200a-200d include in the illustrated form, shown by way of example at the level control 200c, a threaded rod 3 which is inserted in a nut 4 on the underside of the support board 100. An upper end 5a of the threaded rod 3 protrudes through the arcuate guide 2c and beyond the surface of the plate 1 and is preferably formed as a key holder. A lower end 5b of the threaded rod 3 is preferably in a sound-insulating

Base 6 cast.

The plate has a central recess 7, and a hole 8. Furthermore, on one side a shuttering aid 9, which is preferably attached to the plate 1 with angle iron 10a and 10b. On the opposite side of the plate 1 are preferably and exemplarily two lateral stabilizers 11a and 11b, which are adjustable and fixed in each case in guides 12a and 12b. The edges of the plate 1 are preferably covered with a sealing tape 13.

The Fig. 2 shows a schematic representation of a further inventive level control 200e, which together with a plate 1a results in a further embodiment variant of a support board 100a according to the invention. In the plate 1a, a threaded sleeve 14 is inserted and in turn a threaded bolt 15 which has a key receptacle 16 at an upper end, for example in the form of a slot for a screwdriver. The threaded bolt 15 is also rotatable by means of a hexagon 17, which it forms at a lower end. Also there, the threaded bolt also forms a ball 18, which preferably non-positively inserted into a ball socket 19 of a base 20 but is also removable again. On the underside of the base 20, a sound-insulating and to a green floor 22 non-slip contact producing layer 21 is arranged. A significant advantage of the level control 200e is that the ball 18 in the ball socket 19 also rotates upon rotation of the threaded bolt 15 and thus a regulation of a level N of the plate 1a in an adjustment direction 23 without the base 20 and the sound-insulating layer 21 turns.

The Fig. 3 shows, also in a schematic representation, a further embodiment variant of an inventive level control 200f, which together with a plate 1b, a further embodiment variant of inventive support boards 100b results. In the plate 1b, a bore 24 is provided through which a rack-shaped foot 25 is guided and can move freely in the adjustment of a level N ₁ along an adjustment 26 therein, optionally in a longitudinal guide, not shown.

At the bottom of the bore 24, a socket 27 is arranged, in which an upper end of a coil spring 28 is seated, which is arranged approximately parallel to the rack-shaped foot 25. The coil spring 28 springs with a spring force F. The lower end of the coil spring 28 is seated in a corresponding socket 27a, which is embedded in a base 29 together with the lower end of the rack-shaped foot 25. The base 29 stands on a sound insulating layer 30.

In the toothing of the rack-shaped foot 25 - optionally in a double arrangement on both sides - a gear 31 is arranged, which is fastened with a holder 32 on the underside of the plate 1b. The gear 31 has at its center a positive axis bore 33 through which an axis 34 is guided with a round cross-section. With positive fit is meant here that the axial bore may be three-, polygonal or may have a serration.

With spring-assisted movements of the plate 1b along the displacement direction 26 thus the gear 31 rotates in an upward movement (spring force F greater than the weight of the plate 1b) counterclockwise and with a downward movement (spring force F smaller than the weight of the plate 1b) in a clockwise direction ,

In the Fig. 3a For example, a barrier 300, which substantially comprises the axle 34, is shown schematically. This axis is preferably characterized in that it has a first section 35 with a positive cross section and a second section 36 having a round cross-section. The positive cross-section 35 corresponds to the positive axial bore 33 of the gear 31 from the Fig. 3 so that an axial displacement of the axis 34 along a longitudinal axis X locks the gear 31, when the axial bore 33 is displaced from the circular cross-section 36 to the positive cross-section 35. This blocking causes that no longer the spring force F of the coil spring 28 supports the plate 1b, but the gear 31st

The axle 34 preferably has a plurality of sections 35 of positive cross-section and a plurality of sections 36 of circular cross-section in an alternating order, so that with an axial displacement of the axis 34 a plurality of locks 300 can be locked or unlocked simultaneously.

The Fig. 4 schematically shows the adjusted 200g plate 1c of a level N ₂ out in an adjustment direction 37 in a direction indicated further embodiment variant of an inventive support boards 100c with a plate 1c as a further inventive level control system. For this purpose, two toothed plates 40a and 40b are arranged in a base 38, which is supported on a sound-insulating layer 39. With their upper ends, these two toothed plates 40a and 40b are arranged freely running in each case in a leading bore 41a or 41b in the plate 1c. Between the toothed plates 40a and 40b, a bellows 46 is arranged, which raises or lowers the plate 1c by means of compressed air P via a hose 47 with a valve 48.

Basically, the level control could be left while 200g and after the desired level is reached N _2, the plate can be supported or relined 1c. Optionally, however, two symmetrically arranged locks 300a and 300b are provided which are analogous to the barrier of the Figures 3 works. For this symmetrically two brackets 42 a and 42b arranged for each one toothed segment 43a and 43b on the underside of the plate 1c. During upward or downward movements of the folding bellows 46, the toothed segments 43a and 43b rotate accordingly. The toothed segments 43a and 43b are mounted with axle bores 44a and 44b on axes 45a and 45b and analogous to the Figures 3 Lockout. Then no longer the bellows 46 carries the plate 1c, but the locked tooth segments 43a and 43b. This embodiment variant of a support board 100c according to the invention is particularly useful when there is a very close or already closed installation or renovation situation from three sides and operating the rear level adjustments is only very bad or not possible any more. Then, advantageously alone with a pump, the support board 100c be leveled out, if necessary, including the already attached tub.
