1. Field of the Invention
The invention relates to wall mounted toilets, and in particular, to a carrier or a support system for adequately supporting a toilet and the weight of the user.
2. Description of Related Art
Wall mounted toilets or water closets are known in the art. In order to mount a wall mounted toilet to the wall, and in order to support the weight of a user on the toilet, it is common to provide a suitable support system, most of which is disposed behind the wall for supporting both the toilet and related plumbing. An example of such a carrier is a Zurn Z-1203H carrier provided by the Zurn Industries, Inc., Erie, Pa.
It is also known that bariatric toilets need to withstand the weight of the bariatric or obese user. This becomes particularly important when the bariatric toilet is mounted to the wall.
U.S. Pat. Nos. 6,889,392 and 7,146,655 disclose a bariatric toilet seat support apparatus designed to be placed under a toilet seat such that when an individual uses the toilet seat, the weight of the individual is transferred from the toilet seat to the support apparatus thereby avoiding distribution of weight to the toilet itself. These support apparatuses of the prior art generally are a complicated construction located outside the wall and under the toilet seat.
There is a need, therefore, in the art to provide an improved support system for wall mounted toilets that substantially provide support to the user regardless of whether the user is considered as being of normal weight or as being obese or of bariatric weight.
The invention is directed to a support system, also known as wall carriers, for wall mounted toilets that are able to support a greater amount of weight compared to prior art support systems for wall mounted toilets.
The invention provides a support system for mounting a toilet to a wall of a structure and having a first support assembly. The first support assembly includes a faceplate having a first and a second side, and a hole extending through the faceplate; at least two spaced-apart pedestals abutting against the first side of the faceplate; at least two washer plates, each abutting against one of the pedestals; a fitting member having an inlet and abutting against the first side of the faceplate between the pedestals; a coupling positioned within the hole of the faceplate for connecting a discharge port of the toilet to the inlet member of the fitting member; a first fastener connecting the washer plates, the pedestals and the faceplate together and wherein the pedestals are configured to allow vertical movement between the pedestals and the faceplate; a second fastener connecting the faceplate and the fitting member together and wherein the faceplate is configured to allow vertical movement between the fitting member and the faceplate; and a first threaded stud arrangement associated with the second side of the faceplate for positioning the first support assembly relative to the wall of the structure for mounting the toilet.
The invention further provides a support system that in addition to the first support assembly disclosed in the preceding paragraph, also includes a second support assembly. This second support assembly includes the fitting member having a support member with a slot, a second threaded stud arrangement in engagement with the slot of the support member and an anchor foot in engagement with the second threaded stud arrangement for supporting the fitting member on the floor of the structure for mounting the toilet. The anchor foot can be adjusted vertically relative to the first support assembly and the floor of the structure.
The invention further provides a support system that in addition to the first support assembly and the second support assembly disclosed in the above two preceding paragraphs, optionally includes a third support assembly. This third support assembly includes a frame having an opening for receiving the coupling of the first support assembly. The frame is mounted to and supported by the first threaded stud arrangement of the first support assembly. A third threaded stud arrangement is mounted to the frame on opposite sides of the coupling for supporting the frame on the floor surface, and is configured to vertically adjust the frame relative to the first floor assembly and to the floor of the structure.
In the first support assembly, an annular recessed slot is provided in the faceplate and an O-ring is received in the annular recessed slot of the faceplate. A gasket is in alignment with the hole of the faceplate and the inlet of the fitting member of the first support assembly and has threaded holes through which the second fastening arrangement extends for mounting the gasket between the faceplate and the fitting member.
A further embodiment of the invention provides a toilet attached to the wall of a structure including a first support assembly, and optionally, the second support assembly and the third support assembly as described hereinabove. Still further embodiments of the invention include methods for attaching a toilet to a wall of a structure by installing the first support assembly, and optionally, the second support assembly and the third support assembly as described hereinabove, and the methods include adjusting the second and third support systems so they are supported on the floor of the structure.
It is therefore an object of the invention to provide a toilet attached to a wall of a structure having a support system that adequately supports the weight of a user.
It is also an object of the invention to provide an improved support system for a wall mounted toilet having a first support assembly, and whereby a second support assembly and a third support assembly can be added to the first support assembly in order to provide additional support according to the weight of the user.
These and other objects and advantages of the invention will be made apparent from the following description taken together with the drawings.

The support assembly 1 is structured such that it can accommodate a 300 pound load rating without exceeding the deflection requirements as outlined in ASME Standard A112.6.1M, entitled “Floor-Affixed Supports for Off-The Wall Plumbing Fixtures for Public Use”. The support assembly 1 provides for a compact construction in that the overall depth of the support system or the water closet carrier of the invention from the back of fitting member 14 to the front of faceplate 9 measures less than about 9.5 inches, making this a relatively narrow water closet carrier for its positioning between the inner wall IW and outer wall OW of a structure.
Second support assembly 2 relates to the fitting member 14 of the first support assembly 1 of
Support 30, anchor foot 24 and stud 25 provide support to fitting member 14 opposite surface 18 so that some of the weight of the user can be evenly distributed through the support system for supporting toilet T. Thus, this arrangement of support 30, anchor foot 24 and stud 25 avoids the need for the first support assembly 1, i.e., pedestals 11 and faceplate 9, to support the entire weight of a user of the toilet. As is apparent, anchor foot 24 can be adjusted vertically within support 30 via threaded stud 25 to provide sufficient support of the second support assembly 2 against a floor surface. This vertical adjustment of the second support assembly 2 can also be made to coincide with the vertical adjustments made to faceplate 9 and coupling 7 relative to the spaced-apart pedestals 11 for overall support of first support assembly 1 and the second support assembly 2 against the floor surface.
A third support assembly 3 is shown to the left of
