## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Patent Application No. 60/596,935 filed on Oct. 31, 2005 which is incorporated herein by reference.


TECHNICAL FIELD
The present invention relates generally to an apparatus for supporting a toilet, and more particularly to a support for a wall mounted toilet.
BACKGROUND
Wall mounted toilets provide the advantage of improved cleaning ability, since the floor underneath can be accessed with a mop. Wall mounted toilets have a limitation in that they are typically capable of supporting between 300 to 350 pounds, which is somewhat less than a typical floor mounted toilet. The wall mounted toilet is usually supported by a carrier installed inside the wall to which the toilet is attached. Often, the carriers installed inside the wall are only rated to 300 pounds. That is, the toilets secured to the carriers are engineered to hold a person weighting no more than 300 pounds.
There are a number of people that weigh over 300 and many over 400 pounds. If such a person uses a typical wall mounted toilet, they exceed the weight limit of the wall mounted toilet. Since wall mounted toilets are common in hospitals, hotels, airports, and various other locations, there is a likelihood that a person of a weight that exceeds the weight limit of a wall mounted toilet, may use a wall mounted toilet, causing it to break off from its supporting carrier. Injury, discomfort, and embarrassment may result when this happens. Therefore, what is needed is an effective means for supporting a wall mounted toilet, to prevent these situations, thereby reducing injury, as well as legal liability for the owners of facilities with wall mounted toilets.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 shows the use of the toilet support 100 of the present invention in use with a typical wall mounted toilet 102. The mounted toilet 102 is secured to a carrier installed inside the wall (not shown) to which the toilet is attached with a plurality of bolts. The toilet support 100 includes a toilet bumper 104, a support leg 106 and a support foot 108. Toilet bumper 104 is shown in contact with the underside of the wall mounted toilet 102. The toilet bumper 104 is mounted towards the front end of wall mounted toilet 102 so that the bumper can support the toilet in the event that a heavy person is sitting on the toilet. The adjustable support leg 106 is arranged so that an upper end portion 106a is mounted to the toilet bumper 104 and a lower end portion 106b is on the floor. Note that a support foot 108 is provided at the lower end 106b of the adjustable support leg 106 and is adapted to rest against a floor.
FIG. 2A shows a detailed three dimensional view of the toilet support 100 of the present invention. As mentioned before, toilet support 100 is comprised of three main components, a toilet bumper 104, a support leg 106 and a support foot 108. With regard to the toilet bumper 104, it has a three sided curved shape in plane view with a sidewall 118 including a rear wall 120 between two outside corners 122, 124 of the bumper and two side walls 126, 128 between the two outside corners and a front corner 130. The sidewall 118 extends generally in a perpendicular direction (as shown in FIGS. 3 and 4) to a bottom surface 140 of the toilet bumper 104.
As shown in FIGS. 2 and 3, an upper surface 132 of toilet bumper 104 has a concave shape which is adapted to the shape of the bottom of a conventional wall mounted toilet. The bumper 104 is shaped so that when the bumper is mounted to the bottom of a toilet, the front corner 130 is higher than the rear further away than the outside corners 122,124. This can be seen by referring to FIG. 4, where the distance x from where the upper surface 132 intersects the rear wall 120 of the toilet bumper 104 to the bottom surface 140 is less than the distance y from where the upper surface intersects the two side walls 126, 128 at the front corner 130 of the toilet bumper to the bottom surface 140.
Sometimes, the underside of a toilet is shaped so that the concave shape of the upper surface 132 of bumper 104 does not sufficiently engage the underside of the toilet. To accommodate different shaped toilet bottoms, the toilet bumper 104, as shown in FIGS. 2A and 2B, has a removable insert 150 which fits within a three sided cavity 152 formed in the toilet bumper. As shown in FIG. 213, the cavity 152 has two side walls 152a, 152b, a forward wall 152c and a bottom surface 152d. The cavity 152 is formed so that a portion of rear wall 120 of toilet bumper 104 which is between the side walls 152a and 152b is narrower than the remainder of rear wall 120.
The four sided insert 150, as shown in FIGS. 2A and 2B, has two side walls 150a and 150b, a front wall 150c and a rear wall 150d. The upper surface 150e of insert 150 has a concave shape that matches the concave shape of upper surface 132 of toilet bumper 104. The lower surface 150f of insert 150 has a shape that matches the shape of bottom surface 152d of cavity 152. The insert 150 can be inserted within cavity 152 as shown in FIG. 2A so that the toilet bumper 104 is used as a unified structure to support wall hanging toilet 102. Alternatively, insert 150 can be remove from cavity 152 as shown in FIG. 2B. It is also within the terms of the present invention to remove only a portion of insert 150 so that the bumper 104 can accommodate a particular shape of a wall hanging toilet.
Both the toilet bumper 104 and the insert 150 are preferably constructed of a chemical and stain resistant non-porous rubber material such as silicon which can absorb shock created by a heavy individual sitting on toilet 102 and loading the toilet support 100.
Referring to FIGS. 3 and 4, there is shown the bottom of toilet bumper 104. There is shown a bottom surface 140 that would be substantially parallel to a floor on which the toilet support 100 is used. A cylindrical bore 160 extends from bottom surface 140 towards the upper surface 132 of the toilet bumper 104. There is an outer bottom surface 162 of cylindrical bore 160 and an inner bottom surface 154. The outer bottom surface 162 extends closer to the upper surface 132 of the toilet bumper 104 than the inner bottom surface 164. Also, a central bore 166 projects inward from the inner bottom surface 164 towards the upper surface 132 of the toilet bumper 104. The central bore 166 opens to an insert 168 with a threaded bore 170.
Referring to FIGS. 5 and 6, there is shown the adjustable support leg 106. Support leg 106 includes a primary thin walled cylindrical shaped leg section 172 open at opposite ends 174 and 176. A threaded rod 178 projects through the primary cylindrical shaped leg section 172 and is mounted to an interior wall 180 of the primary cylindrical shaped leg section by any means, such as an integral cylindrical sleeve 182. One end of rod 178 projects from end 174 and the other end of rod 178 projects from end 176 primary thin walled cylindrical shaped leg section 172.
The adjustable support leg 106 includes a secondary thin walled cylindrical shaped leg section 184. The secondary thin walled cylindrical shaped leg section 184 is open at one end 186 and has a base portion 188 closing the opposite end 190. The base portion 188 has a threaded bore 192 extending there through and adapted to threadedly receive the threaded rod 178 projecting through the primary cylindrical shaped leg section 172 so that the secondary thin walled cylindrical shaped leg section 184 is telescopedly receive within the primary thin walled cylindrical shaped leg section. By rotating either the primary leg section 170 or the secondary leg section 184, the height (length) of support leg 106 is adjusted.
The end of threaded rod 178 that projects from end 174 of the primary cylindrical shaped leg section 172 is received within the threaded bore 170 of insert 168. As the primary leg section 170 is rotated, the threaded rod 178 moves through threaded insert 168, thereby securing the leg 106 to the toilet bumper 104. Preferably, the primary leg section 170 is rotated until the end cylindrical wall 174 is received in the outer bottom surface 162 of cylindrical bore 160 and the inner bottom surface 164 can be against the integral cylindrical sleeve 182 so that the leg 106 is securely attached to the toilet bumper 104.
In operation, the toilet support 100 may be affixed to toilet 102 by applying adhesive, silicone adhesive or caulking to bumper 104 (note that the bumper can be formed of a silicon material.) Leg 106 is affixed to bumper 104 by the threaded screw 178 engaging screw insert 168 as described herein before. The lower leg member 106a is then rotated until foot 110 makes contact with the floor surface. The lower leg 106a can be rotated in an opposite direction to raise it when cleaning the floor. This provides the cleaning advantages of a wall mounted toilet, with the weight capacity properties of a floor mounted toilet.
It should be noted that no bolts or fittings need to be adjusted on the wall mounted toilet 102 when installing toilet support 100. The bumper 104 can be molded in a color to match the toilet 102, providing a discrete toilet support that blends in with the toilet itself.
