Abstract

A two-part bath or shower base has an acrylic lining (16) with a surrounding substrate (14) of hard polystyrene foam. The substrate locates in and is bonded to a surrounding socket block (17) fabricated of a foam material.

Description

The invention relates to a bath or shower tray, in particular acrylic tub, as well as a tub support for use with such a bath or shower tray and a method.

Bathtubs or shower trays are usually placed and fixed today in foam-made tub supports. The tub supports are usually used at the same time as heat and sound insulation and provide mounting options for each desired wall paneling, can be occupied, for example, with tiles.

A big problem, however, is that baths or shower trays are offered with tub bodies of different dimensions. Thus, almost a corresponding number of tub supports must be kept ready in order to optimally store or fix the respective tub bodies.

In this context, the document describes DE 100 29 461 A1 a bath or shower tray for insertion in a tub support. Between the bath support and bath or shower tray an on-site foam or potting compound is poured. The construction effort is perceived as relatively high.

The WO 00/22971 A1 describes a planar tray support base on which a tub support extension piece is placed by means of pins and recess. The stability of the tub of this prior art is perceived as unsatisfactory.

The DE 198 47 911 A1 discloses a tub support base formed as a planar member which is attached to a tub support extension by means of pins and recesses.

The object of the present invention is to provide a bath or shower tray or a tub support, with or can reduce storage and / or transport costs. Furthermore, production methods for a corresponding bath or shower tray should be specified.

This object is achieved in procedural terms with a method for producing a composite body according to claim 1. Furthermore, this object is achieved in device-technical terms with a bath or shower tray according to the features of claim 4 and a tub support according to claim 9.

In particular, the object is achieved by a bath or shower tray comprising a tub body with an intended for receiving water inside and an outside, comprising: a manufacturer side with the outside of the tub firmly connected tub receptacle with an inside and an outside, wherein the tub receptacle Rigid foam, in particular expandable polystyrene is formed, wherein the tub receptacle and tub body define a composite body, wherein the inside of the tub receptacle and the outside of the tub body are mutually corresponding and substantially flush contiguous, and wherein the outside of the tub receptacle for flush use of the tub receptacle in a trough-shaped Receiving space of a correspondingly designed separate tray carrier is formed by the manufacturer. Between tray and tray support vertically extending guides are effective to ensure a smooth insertion of the inner tub support in the outer tub support in a defined position.

A central idea of the present invention is that the tub body is firmly connected to a tub receptacle of rigid foam, in particular expandable polystyrene, such that a composite body is provided. The tray receptacle can be provided with outer contours, which are designed so that they can be used in a suitably designed tub support. The outer contours of the tub recording can be standardized according to the invention for a group of different tub body of baths or shower trays. It can then be used a uniform tub support for a variety of bath or shower trays.

It is therefore possible for a large number of bath or shower trays, which are designed according to the invention in each case as a composite body, comprising a tub body and a tub receptacle, only very few tub supports available. Due to the fixed connection between the tub body and tub receptacle, it is possible, with a correspondingly corresponding formation of tub receptacle and tub support a tub body on the tub support invention accurately fit into the tub support.

The pan receptacle provided directly on the tub body can bring further advantages. Under certain circumstances, the stiffening effect of the tray receiving sufficient, so that a conventional bathing or showering tubs often provided reinforcement, which is usually made of glass fiber reinforced plastic (GRP), omitted on the outside of the tub body or can be made correspondingly thinner. It Then, a composite body is defined with the elimination of the usual external outer, in particular GfK existing tub reinforcement.

Furthermore, the tub-mounted on the tub body manufacturer already saves packaging material that must be used for storage and transport of the tub conventionally. The pan holder thus serves itself as at least one-sided protection of the tub body.

In a first embodiment, a connecting layer, in particular an adhesive or foam layer, may be provided between the body of the bath and the tub. In a preferred development, the connecting layer also assumes sound-absorbing or sound-damping properties.

In an alternative embodiment, the tub body and tub receptacle without connecting layer are connected to each other by direct foaming of the tub receptacle or pouring the tub body to form a composite body. These two variants are advantageous in that the two elements of the composite body are not constructed separately, but an already manufactured element in the production of the missing element participates.

In a particularly advantageous embodiment, the composite body consisting of tub receptacle and tub body is stackable. This minimizes storage costs. Own packaging material for the tub body can be significantly reduced.

In order to ensure the most stable stacking position, the outer surfaces of the tub receiver are designed to bear on an inner side of an adjacent tub body.

Although it is basically within the scope of the invention to provide only a one-piece, directly attached to the tub body tub receptacle, which simultaneously supports the tub body relative to the ground and preferably also allows the installation of a casing or tiling, the provision of a tub support is preferred. In the last-mentioned case, the tub receptacle has an outer side designed for insertion into a receiving space of the tub support. In a particularly expedient embodiment, the tub support itself is made of individual parts, in particular of longitudinal and transverse walls and optionally a bottom element assembled. Storage and transport costs can be significantly reduced. At the same time optimal handling, stability and functionality in terms of sound and heat insulation can be achieved by a corresponding, preferably normalized outer contour of the tray recording.

In a further concrete embodiment, tub receptacle and tub support are designed so that they can be inserted into each other by 180 ° position offset, so that during installation alignment of the head and foot of the tub (the composite) and at the same time the selection of a particular longitudinal wall of the outer tub support as front free to determine.

Preferably, vertically extending guides are provided between tray receiving and tray support, which ensure the sliding of tub and tray support together with a defined relative position.

In one embodiment, latching means can be effective between tub receptacle and tub support to lock tub receptacle and tub support against each other.

Furthermore, two alternative methods for forming a trough as a composite body according to claim 1 and 2 are proposed according to the invention.

• - Anschäumen der aus Schaumstoff gebildeten Wannenaufnahme (14) direkt an die Außenseite (13) des Wannenkörpers (11).

Accordingly, the object is achieved by a method for producing a composite body, the method comprising the following steps:

• - Providing a mold for foaming a foam, in particular for foaming expandable polystyrene, wherein the mold is provided corresponding to a trough-shaped receiving space of a separately provided to tub support (17);
• - Introducing a tub body (11) of a bath or shower tray, in particular acrylic tub, wherein the tub body (11) provided for receiving water inside (12) and an outer side (13), with its outer side (13) pointing inwards as Stamp in the aforementioned form and
• - Foaming of the formed from foam pan receptacle (14) directly to the outside (13) of the tub body (11).

• - Bereitstellen einer Wannenaufnahme (14) aus Hartschaumstoff mit einer wannenförmigen Ausnehmung (20), einer Innenseite (19) und einer Außenseite (18), wobei die Außenseite (18) zum bündigen Einsatz der Wannenaufnahme (14) in einen wannenförmigen Aufnahmeraum eines separat bereit zu stellenden Wannenträgers (17) ausgebildet wird und
• - Ausbilden einer Bade- oder Duschwanne, insbesondere Acrylwanne, direkt durch Ausgießen der wannenförmigen Ausnehmung der Wannenaufnahme (14).

Furthermore, the object is achieved by a method for producing a composite body, wherein the method comprises the following steps:

• - Providing a tray receptacle (14) made of rigid foam with a trough-shaped recess (20), an inner side (19) and an outer side (18), wherein the outer side (18) for flush use of the tub receptacle (14) is formed in a trough-shaped receiving space of a separately prepared tub support (17) and
• - Forming a bath or shower tray, especially acrylic tub, directly by pouring the trough-shaped recess of the tub receptacle (14).

The core idea of the first alternative method is to bring a cup body with its inside facing outwards as a punch in a mold for forming the tub made of rigid foam, such that the tub receptacle is foamed directly to the outside of the tub body.

In an alternative embodiment, the tub receptacle can be formed first with a trough-shaped recess and then the tub body can be formed directly by pouring the trough-shaped recess.

Since this method is not unproblematic with respect to a uniform tub thickness and a smooth, streak-free inside of the tub body, in a preferred embodiment in a previous step, a surface coating or more generally a surface treatment of the tub-shaped recess of the tub receptacle precede.

• 1 an embodiment of a bathtub according to the invention in cross-sectional view;
• 2 an embodiment of a bathtub according to the invention, which is inserted into a tub support in cross-sectional view;
• 3a an embodiment of a bathtub according to the invention, used in a collapsible tub support in a cross-sectional view;
• 3b an embodiment of a bathtub according to the invention, used in a tub support in longitudinal sectional view;
• 4 a plurality of baths in an embodiment of the invention stacked on each other.

In 1 a first embodiment of a bathtub according to the invention is shown in cross-sectional view. The bathtub initially includes a tub body 11 , for example, made of acrylic or coated with acrylic, or at least partially made of metal may be formed, and a tray recording 14 made of rigid foam, in particular of expandable polystyrene or of another dimensionally stable foam material. The tub body 11 has an intended for receiving water inside 12 as well as an outside 13 on, which may have a - not shown here - gain, in particular made of GRP (glass fiber reinforced plastic). According to a preferred embodiment of the present invention, however, such a reinforcement can also be omitted entirely or at least partially.

The tub intake 14 defined together with the tub body 11 a composite body 16 , as well body 11 and pan recording 14 permanently connected to each other by the manufacturer. In a concrete embodiment, there is a full-surface connection, ie a connection over the entire area of the adjoining surfaces. Alternatively, however, an only partial connection, ie a connection which defines a permanently connected composite body over a plurality of connecting surfaces, may be provided.

when recording 14 and tub body 11 can be directly connected, either by the fact that the tub recording 14 directly to the outside of the tub body 11 is foamed or by the fact that the tub body 11 formed by pouring a previously formed pan receptacle and connected to the tub receptacle. As an alternative to these two types of direct connection, both elements, the tub body, can also be used 11 on the one hand and the tub holder 14 On the other hand, each prefabricated and then connected together via an adhesive or bonding layer.

The tub intake 14 can even with foot elements 27 Be equipped with a parking on a floor surface 21 allow.

Alternatively, the tub intake 14 not directly on a floor surface 21 turned off, but in a conventional or in a specially trained tub support 17 as based on 2 explained, recorded or used. In a particularly preferred and stable embodiment, the tub support 17 while a trough-shaped recess corresponding to the outside 18 the tub reception 14 is trained. Another advantage arises when for a plurality of tub bodies of different dimensions, the tub recording 14 is formed or formed directly in the foaming process, that the tub recording 14 each a predefined design of the outside 18 having.

It can then be a standardized on this outside 18 the tub reception 14 adapted tub support 17 be provided, which then for a possibly quite high number of different tub body 11 different dimensions can be used. The tub intake 14 In this advantageous embodiment of the invention, as it were, as an "adapter" between a more or less arbitrary tub body 11 and a predefined tub support 17 serve.

Like from the 3a and 3b it can be seen on the tub 14 tuned and adapted tub support also be designed separable and, for example, longitudinal walls 22 . 23 , Transverse walls 24 . 25 and possibly a floor element 26 as each comprise separate components. These separate components in the form of longitudinal walls 22 . 23 , Transverse walls 24 . 25 and possibly floor element 26 can be solvable connected via possibly in connection with demountable tub supports per se known connection techniques, such as a tongue and groove connection with dovetail profile. The transport, packaging and storage costs can then be significantly reduced.

In a particularly advantageous embodiment, based on 4 Illustrated is the tray receptacle 14 , in particular the outside thereof 18 designed so that they at least partially in a tub body - in particular of the same type - can immerse, so that the composite body 16 comprising tub body 11 and pan recording 14 (as seen from the cross-sectional view according to 4 visible), is stackable.
