Abstract

The bath support has a base part (2) with a height compensating device (3,4) formed by two wedge-shaped superposed compensating elements set one above the other. One element can be displaced on one side together with the other element relative to the base part and on the other side relative to the other element. The two elements interengage positively. The compensating element can be fixed in the base part by a nail. Where a longitudinal recess (22) is provided in the base part, the recess has detent elements (23) on a long edge protruding into the recess and engaged by detent recesses (24) formed on a long edge of a compensating element.

Description

The invention relates to a tub support, preferably consisting of a rigid foam, for example polystyrene rigid foam, with a base part, height-compensating means being arranged on the base part, for supporting an inserted tray shape.

Such tub supports have already become known in various embodiments. For example, reference is first made to EP-A1 261 521. In this known tub support, a wedge-shaped support element is arranged in the bottom part in a longitudinal recess. Furthermore, it has also become known from DE-OS 44 24 585 to use wedge-shaped compensating elements which have latching feet on the underside, the latching feet engaging in cup recesses in the bottom part of the tub support.

In addition, it is known from DE-C1 44 12 271 to design the bottom of the tub support with transverse ribs which are wedge-shaped in a longitudinal section of the tub support and which cooperate with corresponding ribs of a compensating element. To adjust the height of the compensating element, it is also provided here that these ribs are in turn subdivided in steps.

In view of the prior art specified above, there is a need to design a tub support with height compensation means in such a way that the finest possible height adjustment is made possible.

This technical problem is first and essentially solved in the subject matter of claim 1, wherein is based on the fact that two compensating elements which can be arranged one above the other are provided as height compensating means, both of which are wedge-shaped, a further compensating element being displaceable on the one hand together with the further compensating element relative to the base part and on the other hand relative to the further compensating element. The fact that two wedge-shaped compensating elements are provided enables a large variance with regard to fine-tuning the altitude. This also taking into account the grid restriction given out of the material, in particular in the case of a particle foam, from which the compensating elements and possibly also the tub support preferably consist, if one thinks of a step-like design, because if the grid is chosen too small, there is a risk of breakage or other damage are. A relatively large grid with regard to the fastening means or fastening recesses can be selected with respect to both compensating elements, and an intermediate dimension can nevertheless be achieved in each case by offset from one another. In a further embodiment, it is preferred that the compensating elements can be fixed to one another in a form-fitting manner. In addition, it is preferred that a compensating element or both compensating elements are non-releasably fastened in the base part. E.g. this can be achieved by means of a nail, suitably a plastic nail. In this way, the compensating elements can be preassembled in the factory, based on a specific tub shape to be inserted into the tub support. In particular, it is preferred that such a fastening means passes through both compensating elements and also penetrates into the base part for holding purposes. With regard to the wedge-shaped cross section of both compensation elements, it is also still It is possible that, in addition or as an alternative to a compensating element, the bottom part of the tub support is designed to run in a wedge shape in the longitudinal direction of the tub support with regard to its surfaces interacting with the compensating elements. To fix the compensating elements or at least one compensating element in the bottom part of the tub support, the latter can have a longitudinal recess into which - in the depth direction - a compensating element is at least partially received. In a further preferred embodiment, the longitudinal recess has latching shapes at least on one longitudinal edge in the form of latching elements projecting transversely into the longitudinal recess. A latching recess is correspondingly formed on a longitudinal edge of a compensating element, for the displaceable mounting of this compensating element in the longitudinal recess. As an alternative or in combination with the above-mentioned embodiment, it can be provided that the longitudinal recess has latching recesses formed in rows in the longitudinal direction and that latching feet correspondingly arranged in rows are formed on an underside of a compensating element. For this design, it is also not absolutely necessary for the base part to have a longitudinal recess at all. The locking recesses in the bottom part can also be formed directly on the bottom surface. In addition, an inverted design is possible in the same way, namely that latching protrusions projecting upward in the base part and latching recesses in a row-shaped arrangement are formed in the compensating element. One of the two compensating elements further preferably has, on the one hand, latching recesses which are formed in rows on an underside and, on the other hand, latching recesses which are arranged in a row on an upper side. This compensation element is preferably the middle compensating element, which therefore sits on the one hand on the bottom part of the tub support and on the other hand interacts on the upper side with the further compensating element. The latching recesses can be cup-shaped, the latching feet can suitably have a substantially circular cross section. In a further preferred embodiment it is provided that a compensating element, preferably the upper, in the installed state, directly associated with an underside of the compensating element inserted into the tub support, has a rounded upper side. The curvature is preferably designed to run in a longitudinal direction, at least in relation to the tub support. The upper side of the upper compensating element can also be designed in the form of a polygonal surface, the number of individual surfaces and the respective angle between two individual surfaces being selected such that an approximately rounded surface is achieved. In a further alternative or combinative embodiment it can be provided that latching projections extending transversely on the bottom part of the tub support and projecting upward above a bottom surface of the bottom part (or especially on a bottom surface of the longitudinal recess) and that correspondingly transverse latching recesses are provided on an underside of a compensating element are trained. These locking projections and these locking recesses can, for example, have a square or rectangular cross section (with regard to their three free-standing sides). In a suitable adaptation, it is further preferably provided that a compensating element has transverse recesses or latching projections on its lower or upper side. In addition, it is also preferred that one of the compensating elements or, particularly preferably, both compensating elements can be fixed in the bottom part of the tub support by a nail or the like. This enables the compensating elements to be preassembled in the factory with regard to a specific trough shape.

The invention further relates to a tub support, preferably consisting of a rigid foam, for example a polystyrene rigid foam, with a base part, wherein height compensation means are arranged on the base part, for supporting an inserted tray shape. In order to enable a height adjustment that is as fine as possible, it is proposed that the base part have an inclined surface that rises in the longitudinal and / or transverse direction of the tub support and that the height compensation means can be selectively fixed on the inclined surface. The inclined surface arranged in the base part can be formed, for example, as a wedge-shaped recess, the rising inclined surface preferably being oriented in the longitudinal direction of the tub support. Alternatively, the slope can also point in the transverse direction of the tub support. it is also conceivable to design the inclined surface pointing in both the longitudinal and transverse directions, for example by forming a conical or truncated cone-shaped recess in the base part. The height compensation means, which in a preferred embodiment corresponds to the upper compensation element of the previously described embodiments, can be set selectively on the inclined surface. Depending on requirements, the height compensation means is moved along the rising inclined surface to the desired position and fixed there. In a further embodiment of the subject matter of the invention it can be provided that two inclined surfaces are formed and that the inclined surfaces are in opposite directions Direction. Due to this configuration, a height compensation between the bottom part and the bottom of the inserted trough shape can be carried out with millimeter precision. It proves to be particularly advantageous that the height compensation means is designed asymmetrically in a cross section such that it has an inclined surface which interacts with the inclined surface of the base part. An embodiment is preferred in which the inclined surface of the height compensation means encloses an angle with a vertically oriented side surface, which corresponds to the angle of inclination of the inclined surface of the base part. This ensures that the forces transmitted through the inserted trough are optimally transmitted to the trough support. The selectable fixing of the height compensation means on the rising inclined surface is solved in a preferred embodiment such that the height compensation means can be nailed onto the inclined surface of the base part. This can be achieved in a suitable manner by means of a plastic nail. For this purpose, it finally proves to be particularly advantageous that the height compensation means has a fastening shoulder. The latter is preferably arranged on a side surface of the height compensation means that is aligned in the longitudinal direction of the bottom part inclined surface. It is further preferred to provide such a fastening shoulder on both sides. The actual compensation element for supporting the inserted trough shape is thus formed between the two fastening heels. The fastening heels have these through holes for the passage of a fastening nail. Alternatively, the fastening shoulders can also be provided on the side surfaces of the height compensation means aligned in the transverse direction of the tub support.

A further teaching of the invention proposes that a height compensation means is designed as a compensation element with a lower wedge surface, for cooperation with a counter wedge surface, and that the wedge surface and the counter wedge surface are designed in a helical manner. This configuration makes it possible to provide an effective compensating element with a comparatively small space requirement. Overall, the height compensation means, with the wedge surface and the counter wedge surface, can be a compensation element to be inserted into a tub support, for example to be attached to a tub support base. In addition, it is also possible to mold the lower wedge surface directly into the tub support base. The helical design is further preferably designed such that the wedge surface and / or the counter-wedge surface follows a circular line when projected in a plane perpendicular to a helical axis. It is also proposed that two radially and circumferentially offset wedge surfaces are formed on the compensating element. This makes it possible to prevent a tipping moment. The support can be in two directions perpendicular to each other. Furthermore, a wedge surface can be composed of two individual wedge surfaces arranged one behind the other in the circumferential direction. This affects both the radially outer and the radially inner wedge surface. In addition, it is proposed that the inner and outer wedge surfaces are offset from one another by approximately 90 °. A further development also suggests that wedge surfaces associated with the underside are formed in the tub support base or in another compensating element. It is also preferred to design a first, preferably outer wedge surface of the first compensating element with locking projections. This serves for the safe assignment to the counter wedge surface.

A second, preferably radially inner wedge surface can also be formed with through openings. In this way, pins or the like can be inserted.

a longitudinal cross section through a tub support with a height compensation element according to FIG. 19, wherein the lower part is molded into the tub support base.

A tub support 1 with a base part 2 is shown and described first with reference to FIGS. 1 to 3.

In the illustrated embodiment, three groups of two compensating elements 3, 4 are shown on the bottom part 2, which groups are arranged one behind the other on the bottom part 2 in the longitudinal direction of the tub support 1.

Both compensating elements 3, 4 are wedge-shaped in the longitudinal direction of the tub support and arranged with opposite wedge angles.

The compensating elements 4 have an upper, curved, preferably circularly curved surface 5 which is assigned to a bottom surface 6 of a trough shape 7 inserted into the trough support 1. Because of this curvature, the compensating element 4 interacts with the bottom 6 of the trough shape 7 in a supporting manner in a transverse, strip-shaped surface, because of the deformability given with a particle foam from which the compensating elements 3, 4 preferably consist.

The curved surface 5 of the compensating element 4 can be seen in detail from FIG. 10. In an alternative embodiment, the surface of the compensating element 4 can also be designed in the form of a polygonal surface (cf. FIGS. 11 and 12). The number of individual surfaces is chosen so that an approximately rounded surface 5 'is achieved. In the exemplary embodiment shown in FIG. 11, the surface 5 'is composed of four individual surfaces, the angle alpha enclosed between two individual surfaces being approximately 160 ° -170 °.

The fact that the compensating elements with respect to their wedge shape directed opposite one another preferably one above the other are arranged, there is a very fine adjustability in the vertical direction. E.g. the wedge shapes can be provided so that there is a height shift of approximately 2 mm when displaced by a latching position. The wedge angle in the compensating element 4 can be, for example, 2.5 °. In particular, different wedge angles can also be provided.

It is also advantageous that the compensating element 4 has a bore 8, approximately in its geometric center, which tapers at a certain depth at 9, so that there is a support for a nail head. A bore 8 ′ with a smaller cross section continues to an underside 10 of the compensating element 4. The arrangement is further preferably made in such a way that the bore 8 'opens between two snap-in formations 11 on the underside 10 of the compensating element 4.

In the illustrated embodiment of FIGS. 1 to 3, the latching formations 11 are cone-shaped and corresponding latching recesses 12 are formed in the compensating element 3, which is assigned to an upper side. Furthermore, the compensating element 3 has on its underside 13, the latching formations 11 of the compensating element 4, comparable latching formations 14, which fit into assigned, individually cup-shaped latching recesses 15 in the bottom part 2 of the tub support 1. The locking recesses 12, the locking projections 14 and the locking recesses 15 as well as the locking recesses 11 are each arranged in rows, in the longitudinal direction of the tub support 1.

As can further be seen from FIGS. 2 and 3, the compensating element 3 has an underhand grip 16, approximately with respect to a longitudinal extent, with which the compensating element 3 can be handled in a simple manner. On the one hand, the lower grip 16 is reached by a taper 17 which is formed in the longitudinal direction of the compensating element 3 and which, associated with the underside 13 of the compensating element 3, also tapers further via a step 18, so that it can be reached under by hand.

In contrast, a width b of the compensating element 4 is adapted to a width b 'of the compensating element 3. In the case of an arrangement in the area of the lower handle 16, there is an overhang in the lateral direction of the compensating element 4. Since this compensates for the lower handle 16 in most positions at least partially, this also results in advantageous handling.

In the embodiment of FIGS. 4 to 6, locking projections 19 which are transverse and rectangular in cross section are formed in the compensating element 3. These locking projections 19 engage on the one hand in locking recesses 20 of the base part 2 of the tub support 1 as far as the locking projections 19 are formed on the underside of the compensating element 3 - and on the other hand in locking recesses 21 which are formed on the underside of the compensating element 4.

Incidentally, in this embodiment, too, the compensating element 3 and the compensating element 4 are formed through bores 8, 8 'and 8''for receiving a fastening nail 40, as also indicated in FIGS. 4 and 1. As can be seen in particular from the top view according to FIG. 5, the locking recesses 20 in the base part 2 can be formed with such a width that a transverse displacement of the Compensation element 3 relative to the bottom part 2, and thus also the compensation element 4, is possible.

With regard to the embodiment described above, this can be achieved in the same way by rows of recesses 12 and 15 running side by side.

In the embodiment according to FIGS. 7 to 9, a longitudinal recess 22 is formed in the base part 2 of the tub support 1, which has block-like locking elements 23 projecting transversely into the longitudinal recess 22. These locking elements 23 are provided on both longitudinal edges of the longitudinal recess 22 in the bottom part 2. They extend in a width direction of the longitudinal recess 22 only over a small part of this width, for example 1/10 of the width. Correspondingly, the compensating element 3 has associated locking recesses 24, which extend over the respective height and into which the locking projections 23 - partially, on the bottom side - engage in the assembled state. for the rest, the compensating element 3 according to this third embodiment also has the lower handles already explained approximately in the middle of its longitudinal extent.

The compensating element 4 according to this third embodiment has a lower locking pin 25, which can cooperate with locking recesses 26 on the top of the compensating element 3 for fixing. Incidentally, the through bores already described can also be provided here for a fastening element such as a plastic nail 40.

Furthermore, in the exemplary embodiment shown, the compensating element 4 also has lateral latching recesses which engage the latching recesses 24 in the compensating element 3 correspond. This makes it possible to insert the compensating element 4 directly into the longitudinal recess 22 in the base part 2 and to fix it there with regard to its position. If necessary, the latching foot 25 must then be removed.

In the exemplary embodiment shown in FIGS. 13 to 15, a longitudinal recess 22 'is likewise provided in the base part 2. On the bottom side of this longitudinal recess 22 ', latching recesses 20' are provided transversely to the longitudinal direction of the recess 22 ', for engagement of the latching projections 19 of the compensating element 3.

The depth t of the longitudinal recesses 22 'corresponds in the exemplary embodiment shown to approximately three to four times the depth t' of the latching recesses 20 '. This results in lateral boundary surfaces 30 which prevent the compensating element 3 used from slipping sideways.

With reference to FIGS. 16 to 18, a tub support 1 is shown, which in the area of its base part 2 has three inclined surfaces 31, 31 'rising in the longitudinal direction of the tub support 1. These inclined surfaces 31 and 31 'are formed by wedge-shaped recesses 32, 32' on the bottom.

As can be seen from FIG. 16, the base part 2 has an inclined surface 31 rising approximately in the middle from the right to the left. The depth of the wedge-shaped recess 32 forming the inclined surface 31 corresponds approximately to the material thickness of the base part 2. The inclined surface 31 ends at the floor level.

Further inclined surfaces are provided on both sides of this central inclined surface 31 or of the recess 32, the left inclined surface 31 shown in FIG. 16 being configured in the same direction as the central one. The inclined surface 31 ′ formed on the right side of the central inclined surface 31 in FIG. 16 rises in the opposite direction, a material web remaining between the recesses 32 and 32 ′, the width of which likewise corresponds approximately to the material thickness of the base part 2.

The width of the inclined surfaces 31 and 31 'measured in the transverse direction of the tub support 1 corresponds approximately to the width of the longitudinal recesses 22 and 22' of the previous exemplary embodiments, approximately half the width of the tub support. The remaining residual floor area of the bottom part 2 is smooth and thus designed to be non-slip.

A height compensation means 33 can be selectably fixed on the inclined surfaces 31 and 31 '. These leveling means 33 largely correspond to the leveling elements 4 described in the previous exemplary embodiments. A significant difference to the leveling means 33 in this leveling means 33 is that the underside 34 is smooth and has an inclined surface 35 which is in line with the inclined surface 31 or 31 '. of the bottom part 2 interacts.

In the installed state according to FIG. 16, the side surfaces 36 of the height compensation means 33, which extend in the transverse direction of the tub support 1, are aligned vertically. The inclined surface 35 mentioned is formed on the underside 34 between these side surfaces 36, the slope of the inclined surface 35 corresponding to that of the inclined surface 31 or 31 '.

It can also be seen that the height compensation means 33 is asymmetrical in cross section, corresponding to the previously described compensation elements 4 of the previous embodiments. The height compensation means 33 also has a curved surface 5. In an alternative embodiment, the surface can also be designed in the form of a polygonal surface.

Corresponding to the opposite orientation of the inclined surfaces 31 'to the inclined surface 31, the height compensation means 33 assigned to the inclined surface 31' is also mirrored to the height compensation means 33 assigned to the inclined surface 31 (cf. FIG. 16).

In order to achieve height compensation, the height compensation means 33 arranged on the various inclined surfaces 31, 31 'can be displaced along the inclined surfaces 31, 31' until the desired height dimension is reached. In this position, the height compensation means 33 can be fixed. This is preferably done by nailing by means of plastic nails 40 on the respective inclined surface 31, 31 '.

In order to offer better handling during nailing, each height compensation means 33 has a fastening shoulder 38 on the side surfaces 37 aligned in the longitudinal direction of the tub support 1. Starting from the bottom 34, this extends only over part of the height of the height compensation means 33, the top 39 of the fastening shoulder 38 being oriented horizontally in the installed state according to FIG. 16.

Bores 8 are provided in the fastening paragraphs 38 for the passage of plastic nails 40 or the like.

As a result of this configuration, the plastic nails 40 used for fixing do not have to be struck through the entire body of the compensation means in order to fix the height compensation means 33 on the inclined surfaces 31 or 31 '.

The entire width of the height compensation means 33 including the fastening paragraphs 38, viewed in the transverse direction of the tub support 1, corresponds approximately to the width of the inclined surfaces 31 and 31 ', so that the height compensation means 33 in the area of their fastening paragraphs 38 in the recesses 32 and 32' laterally are.

A perspective view of a further compensation means 41 is shown in FIG. 19, which consists of an upper part 42 and a lower part 43.

Four wedge surfaces 44, 45, 46, 47 are formed in the lower part 43, two wedge surfaces 44, 45 and 46, 47 being arranged radially offset from one another in the circumferential direction one behind the other. Overall, the lower part 43 is annular. In the circular central region, however, a closed ceiling could also be formed, starting below the lowest level of the wedge surfaces 46, 47.

Wedge surfaces 44 ', 45', 46 ', 47' are formed in the upper part in the same way.

A step 48, 49, 50, 51 is formed at the transition of the wedge surfaces 44 ', 45' and 46 ', 47'. The step height corresponds to the gradient of the respective wedge surface, the step heights of two wedge surfaces arranged one behind the other being the same. All step heights are preferably of identical design.

The fact that two wedge surfaces 44, 45 and 46, 47, etc. arranged one behind the other are formed offset by 90 ° to one another, results in the interaction of the upper part 42 and lower part 43 in each case in four areas which are each offset by approximately 90 °. This achieves stability in all directions.

It can also be seen that the wedge surfaces mentioned follow a circular line or a circular section line in a projection into a plane including an angle of 90 ° with the helix axis W.

In further detail, as can also be seen from an overview of FIGS. 20, 21, 22 and 19, locking projections 51 are formed on the outer wedge surfaces 44, 45 and 44 ', 45', but on the inner wedge surfaces 46, 47 and 46 ', 47 'through openings 52. The latching projections 51 and the through openings 52 are likewise each distributed over the wedge surface following a circular line. As can be seen, for example, sixteen projections are formed on a wedge surface 44 and, for example, sixteen through openings 52 on a wedge surface 46. Between the ring of the outer wedge surfaces 44, 45 or 44 ', 45' and the ring of the inner wedge surfaces 46, 47 or 46 ', 47' a circumferential, continuous groove 56 is formed.

In addition, a support block 53 (see FIGS. 23, 24) can be provided, which can also be arranged on a surface 54 of the upper part 42. The support block 53 also has locking projections 55 and through openings 55 '. In the exemplary embodiment, two locking projections 55 and two through openings 55 'are formed.

A fixation can be achieved through the through openings 55 ′, comparable to the above-described embodiments, for example through the described plastic nails 40.

25 shows schematically that the compensating means described with reference to FIGS. 19 to 24, the lower part 43 can be molded directly onto the tub support base 2.

All the features disclosed are essential to the invention. The disclosure content of the associated / attached priority documents (copy of the prior application) is hereby also included in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
