No. 791,296 Ciaims priority, application Sweden Feb. 6, 1958 1 (llaim. (til. 4-2337) The present invention relates to a toilet seat and the object of the invention is to provide a seat which presents advantages in different respects as compared with seats hitherto used. The toilet seat according to the invention is suitably made of resin, preferably a thermo-setting resin.

A toilet seat according to the invention is substantially formed as a horse shoe in that it is open to the rear where it is intended to be pivotably connected to the toilet bowl. if desired it may at this place be provided with reinforcements, egg. in connection with fastenings for hinges.

The advantage obtained with a toilet seat which is open t the rear end thereof is i.a. that this will make possible to maintain better conditions in hygienical respect, since it will be easier to clean both the toilet seat and the bowl at this place than what is the case with closed toilet seats. Furthermore the toilet seat according to the invention does not show any sharp edges which can accumulate dirt. An open toilet seat is somewhat more flexible than a closed seat. This flexibility contributes to a more tension-free structure. Furthermore it seems to be possible to make the tools for the seat easier and more simple and it will likewise be possible to increase speed of production which results in a cheaper price of the final product.

According to the invention the underside of the toilet seat is free from such reinforcing transverse connections which are provided at the seats hitherto known and which serve as a base for the rubber cushions which are intended to rest against the toilet bowl when the seat is used. The freedom from transverse bridges also con tributes to the advantage that the seat is easy to clean. Instead of such transverse connections the toilet seat according to the invention is provided at the underside thereof with two ridges or the like which extend substantially in the circumferential direction. Preferably, however, the ridges do not extend exactly in the circumferential direction but the one end, more specifically the front end of the ridge, is closer to the inner edge of the seat than to the outer edge, while the other end (the rear end) of the ridge is closer to the outer edge of the seat than to the inner edge thereof. The ridges are provided with rubber cushions, preferably on the entire length thereof. By this feature and by the feature that the ridges are directed in the manner just described there is a guarantee that the rubber cushions always rest in a suitable manner against the bowl whatever may be the type of the bowl. Further the bending strength of the toilet seat at the place of said ridges is increased.

The invention will hereinafter be more fully described with reference to the accompanying drawing which shows perspectively one embodiment of the seat according to the invention.

On the drawing 1 designates the seat as seen from below. The seat has substantial horse shoe form since it is not closed to the rear as conventional toilet seats but shows an interruption 3 at this place. Owing to this feature it will be easier to clean the seat and adjacent portions of the toilet bowl at this place. The ends of the seat are provided with reinforcements 5 serving as bases for hinges by which the seat is pivotably connected with the bowl.

In cross section the seat according to the invention has U-shape in conventional manner but is lacking the usual transverse bridges with rubber cushions intended to support the seat from the bowl. Instead thereof the seat according to the drawing is provided with ridges 7a, 7b at the bottom 12 of the U-formed section at opposite sides of the seat. The ridges are provided with rubber cushions 8a, 8b intended to rest against the bowl.

As appears from the drawing the rear end of the ridges lies closer to the outer edge 13 of the toilet seat than to the inner edge 11 thereof, while the front end of the ridges lies closer to the inner edge 11 of the bowl than the outer edge 13. By this feature the advantage is obtained that the toilet seat automatically suits to toilet bowls of ditferent manufacture. Furthermore the ridges provide a considerable reinforcement of the toilet seat with respect to the bending strength at the place where the seat is supported from the toilet bowl. In conventional seats with transverse bridges ruptures often occur at places near said bridges partly owing to insufficient bending strength of the seat between the transverse ridges and partly owing to the internal tensions brought about by the discontinuities along the seat with respect to the thickness of the material caused by said bridges. Thus this drawback has been eliminated by the construction according to the invention. Furthermore the absence of transverse bridges facilitates the cleaning of the seat. In the seat according to the invention the number of corners where dirt may be accumulated is reduced to a minimum.

The rubber cushions 8a, 812 may be fastened to the ridges 7a, 7b in different manners. They may for example be placed as inmouldings atthe moulding of the seat. In this case a partly vulcanized rubber piece may be used which under the action of pressure and heat at the moulding operation becomes finally vulcanized. The rubber cushions may also be fastened by clamping action in known manner and it is also possible to fasten an intermediate fastening portion at the ridges 7a, 7b when the seat is moulded to which intermediate portions and rubber cushions are attached in a suitable manner.

The invention is not restricted to the embodiment shown and described since this embodiment may be modified in different ways within the scope of the invention.

I claim:

A toilet seat construction formed from molded resin material and comprising a U-shaped seat member having a curved front end, opposing sides and an open rear end, said seat member being of channel shaped cross-section and including a web portion and spaced inner and outer flanges, said web portion having an undersurface and said flanges having inner surfaces, said flanges being solely connected at the rear end of the seat member and a ridge formed on the undersurface of the web portion on each of the sides adjacent the front end and extending substantially in a circumeferential direction between the inner surfaces of the flanges, each of said ridges having a front and rear end, said front end lying adjacent to the end of the curved front end of the seat member and the rear end being considerably spaced forward of the rear end of the seat member, said rear end of each ridge lying closer to the inner surface of the outer flange than the front end and the front end lying closer to the inner surface of the inner flange than the rear end.
