Description

The invention relates to a sanitary article with a plastic trough, in particular a bath or shower tray, wash basin or sink.

Trough bodies for sanitary items have always been made of ceramic. Trough bodies made of plastic have recently been added. According to DE 92 15 996 Ul, these are formed from a deep-drawn molded part made of an acrylic resin sheet, which forms an unstable component with insufficient rigidity and structural strength for its intended use and which requires reinforcement. For this purpose, a fully cured, uniform polyurethane layer is bonded to the outside of the deep-drawn molded part. The thickness of the polyurethane layer is selected so that at least the container side walls have sufficient strength without external support. The individual manufacturing steps complicate the manufacture of the trough body and make the product more expensive.

It is also known to produce a plastic deep-drawn part from glass fiber reinforced plastic sheet material, to coat it with laminate to compensate for thin spots that arise during deep-drawing, to cover at least the bottom of the deep-drawn part with a reinforcing plate, e.g. a wooden plate, and to apply a second laminate layer to the inside of the deep-drawn part in order to cover and fix the wooden plate. A trough body of a sanitary object produced in this way is characterized by high material and time expenditure, considerable energy consumption due to high temperature heating of the plastic plates and considerable manual workload when carrying out the individual manufacturing steps. All factors increase the cost of the finished product. In addition, such trough bodies are not recyclable because, for example, an inserted wooden plate is inseparably integrated into the structure. A further disadvantage of the known trough bodies is the relatively high tolerances caused by the layer structure, which can create considerable problems for the installer when installing, for example, a bathtub in a niche.

The invention is based on the object of creating a sanitary article with a trough body made of plastic, which is characterized by high strength and a simple structure.

This object is achieved according to the invention in that the trough body is designed as a plastic injection-molded part.

The plastic injection molded part forms a single-layered, homogeneous body with uniform wall

·

thickness, to which no additional reinforcements need to be added by doubling. The simple wall thickness determines the stability of the trough body, which can be easily adapted to the intended use. The production process of the trough body using the injection molding process takes a few minutes and the high performance of an injection molding machine enables the inexpensive production of baths or shower trays, wash basins or sinks and the like, the stability of which meets the requirements of the finished product from the outset, i.e. without any further processing. Acrylic resin without glass fiber reinforcement can be used as the plastic. Due to the homogeneity of the trough body wall, the sanitary object is fully recyclable. Replacement bathtubs or the like are not disposed of as bulky waste as before, but are shredded and can be reused to produce a new trough body in the form of a plastic injection molded part.

In an advantageous embodiment of the invention, it is provided that stiffening webs are molded onto the outside of the trough body. Furthermore, projections for attaching legs or feet, for example, can be molded on.

The trough body is made of glass fiber-free plastics, because the uniform wall thickness of the trough body generally does not require any such reinforcement. For a bath or shower tray that must be characterized by special strength properties, the trough body can be made in parts from plastics of different hardness. For example, the floor and the transition to the side wall can be made from harder plastics.

The drawing shows embodiments of the invention schematically. It shows:

Fig. 1 is a perspective view of a bathtub and

Fig. 2 is a perspective view of a wash basin.

In a bathtub 10, which essentially consists of an elongated trough body 11 of any shape, the trough body 11 is designed as a plastic injection molded part. This means that the base 12 and side wall 13 of the trough body 11 are molded in one piece from plastic and form a homogeneous container with an open top and a uniform wall thickness. The plastic injection molded part of the trough body 11 also includes a horizontal edge 14 which is molded onto the upper end of the side wall 13 and projects outwards. If necessary, additional reinforcement of the trough body 11 is achieved by stiffening webs 15 which are molded onto the outer surface of the side wall 13 and extend between the base 12 and the edge 14. The stiffening webs 15 are distributed at a mutual distance over the circumference of the trough body 11. The bottom 12 can also have stiffening profiles on the underside, e.g. transverse and/or longitudinal ribs.

Four stiffening bars 15, which are provided in pairs at the two ends of the trough body 11, have a block- or plate-shaped extension 16 at their lower end, which serves to attach feet or legs. These can be screwed tight using bolts inserted through holes 17. If necessary

Feet or legs can also be integrated directly into the plastic injection molded part and molded during the manufacturing process of the trough body 11.

Since no reinforcing inserts, e.g. a wooden plate, are incorporated into the tub body 11 of the bathtub 10, its weight is low compared to known tub bodies. This makes transportation cheaper and assembly easier. Another advantage is the dimensional accuracy of the tub body 11, which ensures that the bathtub 10 can be inserted into a suitable niche in a room without difficulty.

Fig. 2 shows a wash basin 20. The basin body 21 of the wash basin 20 is also designed as a plastic injection molded part. A surrounding horizontal border 24 with a downwardly projecting apron 25 is molded on. The plastic injection molded part of the basin body 21 advantageously also includes a downwardly projecting panel 26 for the drainage area. Reinforcing parts for attaching holding devices can be molded onto the back of the basin body 21. .

Similarly, kitchen sinks can be molded as plastic injection molded parts and, in a single-layer structure, adapted to the requirements of the kitchen by appropriately dimensioning the wall thickness.
