This invention relates to supports and holders for tubular members such as plumbing pipes.
U.S. Pat. No. 5,107,638 to Unertl describes a fixture for mounting water closets such as toilets or urinals directly to the wall of a structure. Unertl describes a floor mounted fixture having an opening for the plumbing drain tube. A bracket is bolted to the fixture and extends upwards and away from the floor, with a hole in the bracket sized to hold a conduit which supplies water to the toilet or urinal. The bracket mounts to threaded studs or bolts that extend from the fixture at predetermined locations, and which determine the lateral position of the bracket relative to the fixture and drain. Unfortunately, when the toilet or urinal is mounted to the fixture, the lateral position of the bracket and the hole in the bracket, is often not aligned with the position of the water inlet on the toilet or urinal. As the bracket positions the water supply conduit, this misalignment between the hole and the water inlet presents problems. There is thus a need for a bracket that allows the position of the hole in the bracket to be adjusted to coincide with the location of the water inlet conduit.
In a broader view existing pipe supports and brackets can have an elongated member with mounting holes, and an opening through which a pipe can extend. The mounting holes are often fastened to pre-existing fixtures, which causes the opening for the pipe to be in a pre-determined location defined by the pipe-opening in the bracket. Unfortunately, the pipe that is to be placed through the pipe-opening is often not located to coincide with the pipe-opening, so the pipe or bracket is bent to allow the pipe to fit through the pipe-opening in the bracket. There is thus a need for a support bracket that accommodates misalignment or offsets of the pipe from the bracket.
A support bracket is provided with an enlarged head sufficient to enclose a plurality of overlapping holes or circular holes spaced apart a distance sufficient to accommodate likely variations in tube or pipe locations. The overlapping holes are preferably of the same radius “R” with the centers of the holes being located on a common axis, and with the holes offset about 0.8R to about 1.8R, and preferably offset about 0.8R to 1.4R and ideally offset a distance about the same as the radius R of the holes. Preferably there are only one or two overlapping holes.
The holes preferably are formed so a lip extends around at least a portion of the circumference of each hole and along the longitudinal axis of the pipe that passes through the hole. Advantageously the lip extends around the entire periphery of the overlapping holes. The lip allows solder or adhesive to be interposed between the lip and the pipe passing through the hole, so as to better fasten the pipe to the bracket. If the bracket is made of metal, the overlapping holes and lip can be stamped from sheet metal. If the bracket is made of plastic, the holes and lip can be molded.
There is thus provided a support bracket for an elongated member having a generally uniform circular cross section of a radius about R. The bracket has an elongated member with a distal end containing a shaped opening formed by two overlapping circles of the same radius R and spaced a distance apart less than the twice the radius, so that an elongated member cannot be placed in each circle during use of the bracket. The circles forming the shaped opening are preferably spaced apart a distance of about the radius R. The shaped opening preferably has an edge with a lip extending from the edge along the length of the elongated member, during use of the bracket. The bracket also preferably has at least one aperture sized to allow the passage of a fastener to fasten the bracket to a fixture during use of the bracket. The at least one aperture is preferably sized to allow the passage of a fastener to fasten the bracket to a water closet mounting fixture during use of the bracket. The shaped opening can be formed in an insert fastened to the distal end, or just formed entirely within and surrounded by the distal end.
The bracket also includes a support bracket for use with a fixture for mounting a water closet connected to a water conduit of radius R, where the fixture has a plurality of bolts at predetermined locations to mount with the bracket during use of the bracket. The support bracket has an elongated member with a longitudinal axis. A first end of the elongated member has at least one aperture sized and located therein to allow the bracket to be fastened to the bolts on the fixture during use of the bracket. A distal end of the b racket has a shaped opening therein, with the shaped opening having circular ends with a radius of about R. The shaped opening has two opposing sides each with a cycloid shape and has opposing cusps of the cycloid shape aligned to define at least two circular openings of a radius of about R. The openings are centered on a straight line perpendicular to the longitudinal axis. Preferably, but optionally, a lip extends from an edge of the shaped opening, with the lip having a cycloid shape. Advantageously there are two openings spaced apart a distance of about R. The first end of the bracket advantageously has a U-shaped cross-section, with the apertures being formed in a bottom of the U-shaped cross section, and with the distal end forming a plate. The shaped opening can be is formed directly in the material of which the distal end is made, or formed in an insert placed in an opening in the distal end.
In a further embodiment, there is provided a support bracket for use with a fixture for mounting a water closet that is connected to a water conduit. The fixture has a plurality of bolts at predetermined locations to which the bracket is mounted during use of the bracket. The support bracket has a fastening end with aperture means for mounting the bracket to the fixture and providing for vertical positioning of the conduit along a longitudinal axis of the bracket during use of the bracket. The bracket has a distal end opposite the fastening end and further has a lateral axis extending through the distal end and perpendicular to the longitudinal axis. There are means on the distal end for positioning the conduit along the lateral axis. The lateral positioning means advantageously comprises a shaped opening formed from overlapping two holes of between about ¾ to about 1 inch diameter. Advantageously there is also provided means for increasing the area of support around a periphery of the shaped opening. Finally, the lateral positioning means is advantageously formed in an insert fastened to the distal end of the support bracket, but could be formed integral with the support bracket itself.
These and other features and advantages will become better understood by reference to the drawings, in which like numbers refer to like parts throughout.

For a conduit 30 with an outer diameter of about 1 inch, each overlapping circle has a diameter of about 1 inch, and preferably slightly larger to allow a slip fit of the conduit through the shaped opening 28. The overlapping circles are preferably spaced laterally apart along centerline 33 a distance corresponding to the radius of each circle, which for the illustrated embodiment is about 0.5 inches. That produces a shaped opening 28 resembling a

The overlapping circles produce a cycloid shape, with a cusp 36 at the points of overlap. The cusp 36 is preferably rounded or broken to prevent a sharp point that may damage the tubes passing through the shaped opening 28. As desired, a flattened area can be provided at the cusp 36. The shaped opening 28 is contained entirely within the distal end 32, with sufficient distance between the opening 28 and the periphery of the distal end to provide a sufficiently strong support for the tube, such as conduit 30, which may pass through the shaped opening 28.

As seen in
Because the shaped opening is formed entirely within the distal end or head 32, there are no separable parts that need to be loosened, removed or tightened in order to allow a shifting of position. The shaped opening 28 also encircles a majority of the circumference of the tubular conduit 30 which advantageously provides a sufficient surface to glue, solder or weld the conduit to the edges of the shaped opening to more securely hold the conduit. Advantageously the overlapping circles forming the shaped opening 28 provide a circular opening having an edge that subtends an arc of about 190°, and preferably have an edge that subtends an arc of about 190° to 240°, although a larger subtended arc could be used to more completely encircle the tubular conduit 30.
The shaped opening 28 supports the bottom of the tubular conduit 30 where gravity urges the conduit against the edges of the shaped opening 28. Providing a lip around at least this bottom portion of the periphery of the opening 28 can help reduce any damage or abrasion caused by the edge of the opening 28 contacting the tubular conduit 30. The amount of overlap of the adjacent circles that form the shaped opening 28 affects the support on the bottom of the opening 28 where gravity urges the conduit 30 against the edges forming the opening 28.

The bracket 24 is preferably formed of a single piece of material. The bracket 24 can be formed from sheet metal or molded material such as suitably strong plastics. The bracket can have various shapes. The illustrated bracket 24 can be made of sheet metal by punching the various apertures 26 and shaped opening 28 in a sheet of metal. The metal can be cut into strips before or after the apertures 26 and opening 28 are formed. The strip of metal can then be bent to form the stiffened U-shaped portion or box-shaped portion or other stiffening shape or other mounting shape, as desired. The lip 38 can be formed during the initial punching operation that forms the shaped opening 28, or alternatively the initial opening 28 can be punched slightly smaller, and a subsequent operation can enlarge the opening while deforming the sheet metal to form the lip 38. As needed, stiffening ridges or flanges can be formed on the head 32. The illustrated bracket 24 can be molded of suitable metal or plastic by shaping a mold to the desired configuration and injecting the molten material.

The shaped opening of
While each of the circles forming the shaped opening 28 could be made a different diameter, each circle preferably has the same diameter. While each of the circles forming the shaped opening 28 could be spaced a different distance D apart, preferably each opening is spaced the same distance D apart. While the axis 33, on which is located the center of the circles forming the shaped opening 28, could be orientated at any angle relative to axis 34, the axes 33, 34 are preferably perpendicular. Thus, the apertures 26 allow variable positioning of the shaped opening 28 along the axis 34, and the overlapping holes or openings forming shaped opening 28 allow variable positioning the conduit 30 along the axis 33. There is thus advantageously provided means on the bracket 24 for providing lateral positioning of the conduit 30 along axis 33. The various apertures 26 also provide means for vertical positioning of the conduit 30 along axis 34. The lateral positioning means include the shaped opening 28 having two opposing sides with cycloid shaped edges. The lip 38 provides means for increasing the area of support around the periphery of the shaped opening, and the preferably lip extends only along the opposing sides of the cycloid, or the lip may extend around the circular ends of the shaped opening 28.
In use, the fastening end of the bracket is fastened to the fixture 20 to which the water closet will be mounted. The vertical positioning of the shaped opening 28 is adjusted as needed using apertures 26 to align the shaped opening 28 with the desired location of the inlet to the water closet and/or the water conduit 30. The water closet may be temporarily placed on the fixture 20 to verify the desired location of the water conduit 30 and the vertical and lateral positioning of the shaped opening 28. The water conduit 30 is then placed through the appropriate portion of the shaped opening 28 and ultimately connected to the inlet on the water closet. If lip 38 is provided, an adhesive may be placed on the lip or otherwise interposed between the lip and the water conduit 30 so as to fasten the lip to the conduit. If the bracket 24 is metal, solder, brazing, welding, adhesives etc. may be used to fasten the lip 38 to the conduit 30.

The insert 42 is preferably, but optionally made of plastic, such as PVC or ABS plastic. The insert allows a single sized opening 40 to allow the shape and size of the shaped opening 28 to be varied. Thus, a single sized opening 40 could accommodate an insert having two overlapping circles of one inch diameter, or another insert having two overlapping circles of ¾ inch diameter, or an insert with different spacing between the overlapping circles, or an insert with various numbers of overlapping openings forming shaped opening 28. This further embodiment thus allows a worker to vary the shaped opening 28 at the time of installation in order to suit the size and location of the water conduit 30.
