Description

The invention relates to a shower tray support with feet and with a frame of profile pieces, which have a support portion for a shower tray and for fixing the feet a C-shaped groove portion in its cross section. The present invention thus relates to a shower tray support in which the shower tray is supported on the frame formed by the profile pieces. To allow height adjustment, the feet are preferably adjustable.

A shower tray support with the features described above is from the DE 20 2006 010 243 U1 known. The frame supporting a shower tray is formed from profile pieces having a downwardly open C-shaped groove portion and upwardly a projecting support leg on which the shower tray rests on a damping profile. At the C-shaped groove portion feet are arranged, which are displaceable along the profile pieces and adjustable in height. The lowest height results from the height of the profile pieces plus the feet arranged underneath. Since the feet must not protrude beyond the outer circumference, they must be made narrow. In addition, the concealed from above by the profile pieces feet are accessible only too hard to set up the shower tray support on a substrate, making subsequent adjustment difficult.

Another shower tray support with profile pieces, which have on their underside a groove for receiving feet, is from the EP 1 181 883 B1 known. Although the well-known shower tray support has proven itself in practice, there is the disadvantage that a considerable minimum height must be maintained here as well.

Against this background, the invention has for its object to provide a universally applicable shower tray support, which is also suitable for very low heights and easy to handle.

Starting from a shower tray support with the features described above, the object is achieved in that the feet are fastened via head elements to the profile pieces and that the head elements are each arranged laterally on an associated profile piece and engage with a holding extension in a slot of the laterally open groove area ,

In contrast to the shower tray carriers known from the prior art, the C-shaped groove area is opened to the side, wherein the head elements are arranged laterally of the profile pieces. The head elements are expediently arranged on the inside of the frame formed by the profile pieces, so that even comparatively wide feet do not go beyond the outer dimension of the frame. Since the head elements are at the height of the profile pieces and preferably not or only slightly extend beyond the profile pieces, a better use of the available space can be achieved. Thus, the adjoining the head elements feet can be made extremely short, which in comparison to the known designs, a significant reduction in height can be achieved. In addition, there is the advantage that the head elements and the adjoining feet are easily accessible after installation of the shower tray support by the lateral arrangement and can be adjusted in a simple manner.

The feet are preferably adjustable in height, which is not mandatory in the context of the present invention. For example, if a minimum Construction height is desired, it may be sufficient to provide the head elements on its underside with a simple plate-shaped element as a foot, which can be achieved that the foot at the bottom of the frame only slightly, for example a few millimeters, protrudes. Alternatively, if an adjustment of the feet is provided in its height, a thread may be provided in the head elements, in which the foot engages with a set screw. Since the thread is arranged as a receptacle for the screws in height of the profile pieces in the context of such an embodiment, both a comparatively large travel and a low overall height can be achieved simultaneously. Finally, it is also possible to provide spacers between the feet and the head elements, in which case the shower tray support can also be universally used for deep shower trays, that is to say large heights. In particular, it is possible to have available a modular system comprising different lengths of spacers and / or different configurations of feet.

According to the invention, the head elements engage with a holding extension in a slot of the laterally open groove area of the respectively assigned profile piece. In order to connect the head elements with the profile pieces, it can be provided to first insert the holding extensions at the ends of the profile pieces and only subsequently from the profile pieces to form the frame, which is preferably closed around the circumference. According to a preferred embodiment of the invention, however, it is provided that the head elements are each held in a first functional position on their holding extensions along the profile pieces displaceable and perpendicular thereto positively in the groove area, wherein the positive connection is canceled in a second functional position, so that the head elements in the second functional position from the respective associated profile pieces are removable. In the context of such an embodiment, it is also possible, initially a self-contained Form frame from the profile pieces and only then to arrange the head pieces. For this purpose, the head pieces are then introduced in their second functional position in the profile pieces and then, for example, by a rotation, moved into the first functional position and secured against falling out. As described above, in the first functional position, the head elements connected by their holding extensions with the profile pieces initially remain movable along the profile pieces, whereby an exact positioning is made possible. For example, if the floor on which the shower tray support is to be placed, partially uneven or not sustainable, the feet can be placed outside such areas. Since in the described preferred embodiment, the foot elements can be hung in a simple manner in the C-shaped, laterally open groove area, it is also possible to subsequently add more feet. This can be useful, for example, if an increase in the carrying capacity of the shower tray support to be achieved. In the context of the present invention, such an exact adaptation to the respective requirements is possible, wherein the individual parts for the formation of the shower tray support can be kept modular for different applications.

According to a preferred development of the described embodiment releasable securing means are arranged on the head elements in order to hold the head elements in the first functional position. During assembly, the head elements are then inserted in the second functional position with their holding extensions in the C-shaped groove regions and brought into the first functional position. In order then to prevent the head elements from getting back into their second functional position, the securing means is then transferred to a blocking position. As a securing means, for example, a locking screw may be provided which in a thread of the associated head element held and in the first functional position in the lateral slot of the Nutenbereichs can be screwed.

In the context of the invention, it is expedient if the head elements can be locked after positioning at a desired location on the profile pieces. Such locking can be done for example by the locking screw described above, if they are finally pressed in a further tightening against the associated profile piece, whereby a locking of the head element takes place.

According to the invention, the frame has a support region for a shower tray. The frame is thus not only intended to connect the individual foot elements together, but also to absorb the weight of the shower tray, which is why the frame must be made sufficiently stable taking into account the weight forces occurring when using a shower tray. Furthermore, the profile pieces on a C-shaped groove portion, the opening slot extends laterally. On this basis, the scope of the invention provides various design options for the cross-sectional shape of the profile pieces.

In the simplest case, the profile pieces are designed as simple C-profiles, wherein the support area for the shower tray is formed by an upper leg of the C-profile. According to a preferred embodiment it is provided that the profile pieces in cross-section have an upwardly projecting web on which rests the shower tray in the assembled state. Conveniently, an elastomer element, for example a U-shaped profile strip made of an elastomeric material, is provided between the web and the shower tray.

The laterally extending slot of the C-shaped groove portion usually extends on the inside of the frame. On the outside of the frame can optionally be provided an upwardly open channel or a holding web for a seal. By such a configuration can be avoided that, especially in very shallow shower trays flowing laterally over the edge of the shower tray Krichwasser flows uncontrollably, which would exist the risk of damage to the adjacent building fabric. If the profile pieces have an upwardly open channel, a water outlet can be connected to at least one of the profile pieces in order to be able to dissipate the water collected in the channel. In order to achieve sufficient tightness in profile pieces with an upwardly open channel, it is expedient to connect the frame-forming profile pieces cohesively, for example by welding together. In such an embodiment, it is particularly advantageous if the head elements as described above, can be subsequently introduced with their holding extensions in the C-shaped groove area.

Alternatively, the profile pieces can also be connected to the frame by connecting elements, in particular corner connecting elements. In such an embodiment, additional feet may be provided on the connecting elements, which are not arranged on head elements but on the connecting elements.

alternative embodiments of feet in a representation according to the Fig. 2 ,

Fig. 1 shows a shower tray support having feet 1, which carry a closed, rectangular frame 2, which is formed from profile pieces 3. According to the illustrated embodiment, the profile pieces 3 are positively connected to each other at the corners by welds. According to an alternative embodiment, not shown, the profile pieces 3 can also be connected by connecting elements to the frame 2.

The detail view of the Fig. 2 It can be seen that the profile pieces 3 have in their cross section an upwardly projecting web 4, which defines a support area for a shower tray 5. Between the web 4 and the shower tray 5, a U-shaped elastomer element 6 is arranged, which on the one hand ensures a uniform force distribution and on the other hand an acoustic decoupling between the shower tray 5 and the frame 2.

According to the invention, the profile piece 3 shown in cross-section on a C-shaped groove portion 7 with a lateral slot 8. Laterally of the profile piece 3, a head element 9 is arranged, which engages with a holding extension 10 in the slot 8 of the laterally open groove portion 7.

On the underside of the head element 9 is adjustable in height foot 1 is arranged. In order to enable an adjustment, the foot 1 in the illustrated embodiment, an adjusting screw 12 which engages within the head member 9 in a thread, wherein by rotation of the adjusting screw 12 of the foot 1 to a in the Fig. 2 unscrewed position can be unscrewed. In particular, a reducing sleeve or a different use in the head element 9 can be provided for receiving the adjusting screw 12, whereby an adaptation to different thread diameter of different screws 12 is possible when replacing the Reduzierhülse or the insert. In order to allow a slight rotation even with a ground contact of the foot 1, a foot cap 13 is clipped onto the adjusting screw 12.

Since the head element 9 is arranged laterally of the profile piece 3, the shower tray support can also be used for very low heights and thus very flat shower trays. Another advantage is that the foot 1 is spaced from the outer circumference of the frame 2 by the lateral arrangement of the head element 9 on the inside of the frame 2, whereby on the one hand stable feet 1 can be used with a greater width and on the other hand, the feet. 1 particularly easy to access and adjust. In the Fig. 1 are optional spacers 20b, 20c shown below in connection with the Fig. 5c be explained.

At the in Fig. 2 the usual extension of the foot 1 shown, the holding extension 10 in cross section to a complementary shape to the groove portion 7, wherein the ends of the C-shaped groove portion 7 engage in a taper on the holding extension 10. The head element 9 with the foot 1 arranged thereon is therefore held positively in a direction perpendicular to the profile piece 3 and without further locking along the profile piece 3 movable. The Fig. 2 shows the head element 9 in the mounted state in a first functional position.

As in the Fig. 3a and 3b is shown, the head element 9 by a rotation about a horizontal, perpendicular to the associated profile piece 3 standing axis A of the first functional position ( Fig. 3b ) into a second functional position ( Fig. 3a ) are transferred. In the second functional position of the positive connection between the holding extension 10 and the C-shaped groove portion 7 is repealed, so that the head element 9 in the second functional position in the respective associated profile piece 3 can be inserted and removed. In order to make this possible, the holding extension 10 is chamfered, so that the height of the holding extension 10 in the second functional position is less than the width of the slot 8.

In order to use a head element 9 at any point on a profile piece 3, the holding extension 10 is inserted in the second functional position of the head element 9 in the C-shaped groove area. By a rotation of the head element 9, a positive locking is then achieved in the first functional position, which prevents lateral slipping out of the holding extension 10 from the C-shaped groove portion 7. In order to avoid that the head element 9 accidentally gets back into the second functional position, a locking screw 14 is provided as securing means on the head element 9, which is held in a thread of the head element 9. According to the illustrated embodiment, the thread of the head element 9 is provided by a hex screw, which is inserted into a correspondingly shaped recess. When the locking screw 14 in the first functional position ( Fig. 3b ) is screwed, the threaded portion of the locking screw 14 enters the slot 8 of the C-shaped groove portion 7, whereby the head member 9 is held in the first functional position. After that then Head member 9 has been moved along the associated profile piece 3 in a desired position, the locking screw 14 can be tightened so far that it presses against the profile piece 3, whereby the head member 9 is locked relative to the profile piece 3. By re-loosening the locking screw 14, the head element 9 can be subsequently readjusted or taken out.

The described embodiment, which allows a lateral insertion of the head elements 9 in the profile pieces 3, also allows first to form the frame 2 of the profile pieces 3 and to connect the profile pieces 3 cohesively with each other. Furthermore, additional head elements 9 with feet 1 to be fastened thereto can be subsequently added to increase the carrying capacity.

For the design of the profile pieces arise within the scope of the invention, various possibilities. That's how it shows Fig. 2 a preferred embodiment in which the profile pieces 3 on the outside of the frame 2 have an upwardly open channel 15. In the area of this channel 15, the shower tray 5 ends with a bent edge 16. Side of the shower tray 5 running down Krichwasser is collected in the channel 15, whereby an uncontrolled flow of Krichwassers is avoided. To dissipate this creep is, according to the Fig. 1 connected to one of the profile pieces 3, a water outlet 17 to the upwardly open channel 15, wherein the creep water is passed from the water outlet 17 through a hose to a siphon, not shown.

The Fig. 4a and 4b show alternative embodiments of the profile pieces 3, wherein according to the Fig. 4a a simple cross-sectional profile is provided, which consists essentially of the C-shaped groove portion 7 and the upwardly projecting Bridge 4 exists. In order to achieve a high load capacity, extends as in the embodiments according to Fig. 2 and Fig. 4b an upper transverse web 18 beyond the C-shaped groove portion 7 in the direction of the head member 9, so that the profile pieces 3 not only rest in the region of the holding extensions 10 of the head elements 9. A marginal recording of creep is in one embodiment according to the Fig. 4a not provided.

Fig. 4b shows an embodiment in which opposite to the C-shaped groove portion 7, a holding web 19 is provided for a seal, whereby the sealing against an adjacent wall is made possible.

Since, according to the invention, the head elements 9 are arranged laterally of the profile pieces 3, the shower tray support according to the invention can also be used for particularly flat shower trays which require a particularly low installation height. The Fig. 2 shows in this context a possible embodiment with an adjustable foot 1. However, the shower tray support by an exchange of the feet 1, 1 'and / or the arrangement of spacers 20a, 20b, 20c are adapted to different heights. That's how it shows Fig. 5a a particularly flat foot 1 ', which is placed directly on the underside of the associated head element 9 and projects only a few millimeters from the profile piece 3 down. With the described arrangement 5 building heights of less than 50 mm can be achieved with respect to the upper edge of the shower tray.

Fig. 5b shows starting from an embodiment according to the Fig. 2 the possibility to allow a larger height by the arrangement of a spacer 20a. The advantage here is that even a longer screw 12 of the foot 1 can be used, which additionally also the available travel is increased.

By different lengths spacers 20 a, 20 b, 20 c any adaptation to a desired height is possible. Fig. 5c shows in this context, by way of example, the arrangement of second spacers 20b, 20c with different lengths between the foot 1 and the head element 9. In particular, the various components can be kept as a universally applicable system, depending on the application, the appropriate components can be selected. In addition to different heights also different payloads by the number of feet 1, 1 'can be achieved.
