Description

June 5, 1962 F. KLElNHOF FLOOR CONNECTION FOR TOILET BOWLS Filed April 19, 1960 Hll...
United States Patent 3,037,212 FLOOR CONNECTION FOR TOILET BOWLS Ferdinand Kleinhof, Dorpsstraat 57, Diepenveen, Netherlands Filed Apr. 19, 1960, Ser. No. 23,264 Claims. (Cl. 4-252) The invention relates to a floor connection for a toilet bowl, and in particular to means for connecting the discharge pipe of a toilet bowl with a waste pipe.
In the conventional floor connection for toilet bowls, use is generally made of a leaden sleeve, in which the discharge pipe of the toilet bowl is inserted. A gasketing substance, such as hemp impregnated with bitumen, is applied between the inner surface of the sleeve and the outer surface of the discharge pipe. The top end of the sleeve is subjected on the spot to a deformation so as to obtain a flange to be supported by the floor. A peripheral base flange of the discharge pipe is placed upon said flange of the sleeve. The lower end of the sleeve is inserted in the enlarged end of the waste pipe, and the space between the inner surface of the same and the outer surface of the sleeve is filled with a gasketing substance, such as minium and tar.
This conventional floor connection is expensive, not only on account of the relatively high costs of the leaden sleeve, but also because several complicated operations are to be performed on the spot by a skilled plumber.
It is an object of the present invention to remove this disadvantage, and to provide a satisfactory floor connection for toilet bowls which makes use of inexpensive parts and may be assembled with a minimum of labor.
Another object of the invention is to provide a connection between the discharge pipe of a toilet bowl and a waste pipe, which is perfectly tight, so as to prevent the occurrence of leakages and odors, but nevertheless inexpensive and easy to assemble.
Further objects and advantages of the invention will appear from the following description, given with reference to the accompanying drawing, in which FIG. 1 shows a longitudinal section of a floor connection according to the invention for toilet bowls having a central discharge pipe.
FIG. 2 shows a longitudinal section of a modification of the sleeve used in the connection of FIG. 1.
FIG. 3 shows, partially in elevation, and partially in a longitudinal section, a connection according to the invention for toilet bowls having a lateral discharge pipe.
FIG. 4 is an enlarged view of a part of the connection shown in FIG. 3.
FIG. 5 shows a longitudinal section of a modification of the sleeve used in the connection of FIGS. 3 and 4.
According to a main feature of the present invention, use is made of an at least partially conical sleeve made of an elastic synthetic resin, such as polyethylene, of which the wide end encloses the discharge tube of the toilet bowl, and the narrow end is inserted in the waste pipe.
For toilet bowls provided with a central discharge pipe and with a base flange on said discharge pipe, use is preferably made of a sleeve having a peripheral flange with a depending edge, the flange of the sleeve being immediately supported by the floor, and the base flange of the discharge pipe being placed upon the flange of the sleeve.
For toilet bowls provided with a lateral discharge pipe, it is preferred to use a sleeve provided at its wide end with an inwardly directed flange enclosing the discharge pipe, and at its narrow end with an outwardly directed flange laid against the inner surface of the waste pipe.
Referring now to FIG. 1, the central discharge pipe of a toilet bowl is indicated at 1. A base flange 2 is pro- 3,037,212 Patented June 5, 1962 vided on the discharge pipe 1. A conical sleeve 3, made of an elastic synthetic resin, such as polyethylene, is provided at its wide end with a peripheral flange 4, having a depending edge 5. The flange *4 with its depending edge 5 is immediately supported by the floor 6. The narrow end of the sleeve 3 extends into the waste pipe 7, of which the top edge lies at the same level as the floor 6.
In assembling the connection, the toilet bowl is inserted with its discharge pipe 1 into the wide end of the sleeve 3, whereby a tight joint between the discharge pipe and the sleeve is obtained due to the elastic properties of the sleeve. In the final position of the toilet bowl, the base flange 2 exerts a pressure on the peripheral flange 4 of the sleeve, whereby the required joint with the floor 6 is obtained. If the flange 3 were completely flat, the tightness of the joint with the floor might be destroyed by an uneven surface of the floor. Due to the depending edge 5, however, a tight joint is warranted under any circumstances. It has been found in practice that no leakage occurs even when the waste pipe is completely clogged up.
The height of the conical sleeve 3 may amount to about 4 inches, while the inner diameter may amount to 4 inches at the narrow end and to 4.4 inches at the wide end. The flange 4 may have a width of about 1 inch, and the thickness of the wall of the sleeve may be about 0.08 inch.
In contrast with the conventional floor connections, the waste pipe 7 need not be provided with an enlarged end. Although a wooden floor has been shown in FIG. 1, the connection may also be used vw'th a concrete floor.
in the modification of the sleeve 3 shown in FIG. 2, an inwardy directed flange 8 is provided at the top end of the sleeve. This flange is adapted to enclose a discharge pipe having a smaller diameter than the top end of the sleeve with a sufficient resiliency to obtain a tight joint between the discharge pipe and the sleeve. Thus, it will be seen that the flange 8 allows for the use of the sleeve in combination with discharge pipes of varying diameter. The flange 8 may be secured to the sleeve by a heat sealing procedure. It is also possible, however, to attach the flange 8 to a separate annular disc having a depending edge, which is placed on the flange 4 so as to grip with its depending edge around the edge 5.
In FIGS. 3 and 4, the lateral discharge pipe of a toilet bowl is indicated at 9. FIG. 3 shows how this discharge pipe is connected with the bowl 10. A sleeve 11, consisting of two cylindrical sections and an intermediate conical section 12, and made of an elastic synthetic resin, such as polyethylene, is provided with an inwardly directed flange 13 at its wide top end, and with an outwardly directed flange 14 at its narrow lower end.
In assembling the connection, the sleeve 11 is first inserted with its narrow end in the waste pipe 7, so that the conical section 12 lies against the top edge of the waste pipe. The flange 14 impinges against the inner surface of the waste pipe so as to form a tight joint between the sleeve and the waste pipe. The discharge pipe 9 is now inserted in the wide end of the sleeve, in such manner that the thickened end 15 of the discharge pipe is pushed through the opening of the flange 13. The flange 13 impinges against the outer surface of the discharge pipe 9 so as to form a tight joint between the discharge pipe and the sleeve. The assembly only takes a few minutes.
In the modification of the sleeve 11 shown in FIG. 5, a resilient skirt 16 is attached to the sleeve at the border line between the upper cylindrical section and the conical section. The skilt 16 serves to cover the top edge of the waste pipe, and is particularly useful in cases Where the top edge of the waste pipe extends above the floor surface, which would otherwise lead to an untidy appearance.
Although the invention has been described hereinbefore by reference to some specific embodiments, it is to be understood that many modifications and alterations of these embodiments are possible with the scope of the invention as set forth in the appended claims.
