DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

(9) A brace is described herein for bracing and thereby supporting a toilet tank against a wall. The brace may also have other applications for bracing and supporting an object that is near a wall. The brace may also serve as a spacer in a vertical orientation, such as for leveling an object resting on a floor.

(10) With reference to FIG. 1, a side elevation of a brace 10 is shown connected to a toilet tank TT and extending to a wall W for supporting the toilet tank TT against the wall W. The toilet tank TT is connected to and sealed with a toilet bowl TB using a conventional connection C, the details of which are not shown in FIG. 1, but are described as follows. The toilet tank has a centralized opening in a bottom wall. The toilet bowl has a mating opening with an upwardly extending flange. A gasket is received on the flange below the toilet tank. Each of the toilet tank and the toilet bowl has a bolt hole on each side of its respective opening. A pair of bolts secure the toilet tank to the toilet bowl in a watertight seal provided by the gasket. The toilet tank is illustrated as spaced from the wall by about three inches or about 5 to 10 cm. Without the brace 10, the: only support for the tank against a lateral force is through the bolts at the bottom of the tank.

(11) FIG. 2 is a top plan view showing a pair of braces 12 and 14 spaced between the toilet tank TT and the wall W. A lid L covers the tank TT and is shown partially cut away to fully expose a top view of the braces 12 and 14. Brace 12 is fastened to the tank TT by a downwardly-facing, U-shaped clip 12a. An alternative way of connecting a brace to a toilet tank is to glue or bond the brace to the toilet tank. Brace 14 has a plate 14a and a layer of adhesive 14b, which bonds the brace 14 to the toilet tank TT. A brace according to the present invention can be used in applications other than for bracing a toilet tank, where the use of a flat or shaped plate and an adhesive may be a better fastener system than a U-shaped clip.

(12) FIG. 3 is a cross-sectional side elevation of a brace 20 between a toilet tank wall TW and a room wall RW. A U-shaped clip 22 rests on an upper edge of the tank wall TW. Clip 22 has opposing side plates 22a and 22b connected by a base plate 22c. A stud 24 is fixed to and projects perpendicularly from the clip side plate 22b. Stud 24 has male threads 24a. A nut 26 has a central longitudinal hole 26a on one end, and the sidewall that defines the hole 26a has female threads 26b. Nut 26 is threaded onto stud 24. The other end of nut 26 has a central longitudinal recess 26c. A first spacer 28 has a central longitudinal projection 28a on one end sized for and pressed into the recess 26c in an interference fit, which fastens the first spacer 28 to the nut 26 in an attachable-detachable coupling system. The other end of the first spacer 28 has a central longitudinal recess 28b. A second spacer 30 has a central longitudinal projection 30a on one end, which preferably has the same size, shape and location as the projection on the first spacer 28. The projection 30a is pressed into a friction fit or interference fit with the recess 28b on the first spacer 28. A recess 30b is provided on the end opposite the projection 30a. The recess 30b preferably has the same size, location and shape of the recess 28b for uniformity of parts. An end cap 32 has a central longitudinal projection 32a sized and located for reception in the recess 30b of the second spacer 30, which detachably attaches the end cap 32 to the second spacer 30. End cap 32 has a surface 32b on its end opposite the projection 32a. Surface 32b rests against or presses against the room wall RW and is preferably generally planar or flat.

(13) The first and second spacers 28 and 30, respectively, have different lengths, and more spacers can be used, which provides flexibility in arranging a number of spacers so that the brace 20 fits reasonably well in the space between the toilet wall TW and the room wall RW. A final adjustment to the length of the assembled brace 20 is made by rotating the nut 26 with respect to the stud 24, which alters the combined length of the tank brace 20 for bracing the toilet tank against the room wall RW so that the room wall provides support for the toilet tank to resist a lateral force that tends to push the toilet tank toward the room wall.

(14) FIG. 4 is an exploded-view drawing of a tank brace kit 40. The kit 40 includes a U-shaped dip 42; a threaded stud 44 projecting from the clip 42; a nut 46 that has female threads for threaded engagement with the stud; first, second, third and fourth spacers 48, 50, 52 and 54, respectively; and an end cap 56. The U-shaped clip has opposing sides 42a and 42b, which are connected together by a base 42c. The angle between the side 42a and the base 42c is acute, and the clip 42 is preferably made of a material that has a spring-like resilience. The sides 42a and 42b press against a toilet tank wall for securing the tank brace to the toilet tank in a friction fit. An alternative to the U-shaped clip 42 is a flat plate such as plate 42b and an adhesive for bonding the plate to the toilet tank wall. In either embodiment the stud 44 should point towards the room wall. Nut 46 is shown in cross-section. FIG. 5 is a view of the full nut 46 as seen along the line 5-5. Nut 46 has a central recess 46a that is defined by female threads 46a for engagement with stud 44. For a reduction in material cost, nut 46 has a number of voids 46b. An internal cylinder 46c is connected by a web of material between the voids 46b to an outer cylinder 46d. The central recess 46a is within the internal cylinder 46c. Nut 46 has an interlocking recess 46e on its end opposite the threaded recess 46a.

(15) First spacer 48 in FIG. 4 is shown is cross-section and has an interlocking projection 48a for a press-fit engagement with the interlocking recess 46e in nut 46. First spacer 48 has an interlocking recess 48b opposite its projection 48a. FIG. 6 is a view of the full first spacer 48 as seen along the line 6-6 in FIG. 4. First spacer 48a has an outer cylindrical wall 48c and an inner cylindrical wall 48d. Walls 48c and 48d define an annular void space 48e. The outer wall has a notch or pin hole 48f. Second spacer 50 has an interlocking projection 50a that press fits in recess 48b and an opposing interlocking recess 50b. Second spacer 50 has a projecting pin 50c that fits in the pin hole 48f in first spacer 48. As can be seen in FIG. 6, the first spacer has a plurality of ridges 48g and valleys 48h spaced around an outer circumference. The nut, each of the spacers and the end cap 56 have corresponding ridges and valleys. The pin 50c is received in the pin hole 48f, which tends to prevent the second spacer 50 from rotating with respect to the first spacer 48, thereby keeping the ridges and valleys in alignment. Corresponding pins and pin holes are provided in each of the nut, the spacers and the end cap for keeping the ridges and valleys along the brace in alignment. The ridges and valleys around the nut 46 provide a gripping surface for rotating the nut. Third spacer 52 has an interlocking projection 52a, an interlocking recess 52b and a protruding pin 52c.

(16) FIG. 7 is a view of third spacer 52 as seen along the line 7-7. The interlocking pin and pin hole combination, which is for preventing rotation of one spacer with respect to another spacer for keeping the ridges and valleys in alignment, is an optional feature. A smooth cylindrical shape with a circular cross-section could be used, where there would be no need for maintaining an alignment. An alternative design, which would maintain alignment, is for the projection-recess coupling system to have a non-circular cross-section. For example, the recess 48b and the projection 50a could each have a mating non-circular cross-section, such as a rectangular or oval cross-section, which would provide an interlocking mechanism that would not readily allow rotation of one spacer with respect to another spacer or with respect to the adjusting nut 46. Another alternative design, which would maintain alignment, is for the projection-recess coupling system to have more than one recess, such as two, three or four recesses, and a mating number of projections.

(17) A kit such as the kit in FIG. 4 can have more than one brace, preferably two braces for the arrangement shown in FIG. 2. A number of different spacers of different lengths can be included so that different combinations are suitable for different gaps between a toilet tank and a wall. Prior art braces such as described in U.S. patent application Ser. No. 2015/0191902 A1 by Vadnais required cutting an element to fit a particular gap, but a brace according to the present invention does not require that an element be cut. There is no need to cut anything to size or length with a brace according to the present invention. One merely determines a gap distance between a toilet tank and a wall; threads an adjusting nut onto a stud on a U-shaped clip; assembles a combination of spacers that with the adjusting nut has a combined length of slightly less than the gap distance; remove the toilet tank lid; place the U-shaped clip on a top edge of a back wall of the toilet tank (or stick a plate on the outside back wall with an adhesive); rotate the adjusting nut to increase the combined length of the brace to the gap distance so that the brace presses against the room wall and supports the toilet tank against the room wall; repeat if desired to use a second tank brace; and replace the lid on the toilet tank.

(18) The adjusting nut allows one to obtain a reasonably precise combined length for the brace. The threaded stud 44 does not necessarily need to be attached to the mounting bracket 42. A threaded stud can be anywhere along the longitudinal axis of the brace, such as on the end cap 56, with an adjacent adjusting nut. However, the threaded stud and the adjusting nut are not required and can be eliminated from the brace. A different U-shaped clip or adhesive-lined plate can be used in which the threaded stud is eliminated and replaced with an interlocking mechanism, preferably a recess for receiving a projection such as the projection 48a on the first spacer 48 in FIG. 4 in an interference fit. A combination of spacers can be assembled to provide a combined length that is most suitable for a particular gap distance. The projection-recess coupling system described above could have two, three, four or more recesses and two, three, four or a mating number of projections, which provides a different way to prevent rotation of one member with respect to another member or spacer. Different interlocking mechanisms can be used instead of the projection-recess coupling system described in reference to FIGS. 3 and 4. The projection-recess coupling system described with reference to FIGS. 3 and 4 could be called a stud-and-tube coupling system. However, that terminology is also used with reference to toy building blocks described in U.S. Pat. No. 3,005,282, issued to Christiansen, assigned to Interlego, A. G. and incorporated by reference. The interlocking mechanism described in the U.S. Pat. No. 3,005,282 patent does not place a projection inside a tube. The U.S. Pat. No. 3,005,282 patent describes building blocks in which an upper surface has projecting studs and a lower surface has a tubular structure such as seen in FIG. 6 herein, except the blocks or bricks in the '282 patent have a square or rectangular shape rather than the cylindrical wall 48c shown in FIG. 6. The studs on a brick or block in the '282 patent are not received inside a tube, but are instead received in a space between an outer surface of a tube and a wall and or with the outer surface of an adjacent tube. A stud in the '282 patent is received in a space defined by the outside wall of one or more tubes and an inside wall of a brick or block. The interlocking mechanism described in the '282 patent has been referred to as a stud-and-tube coupling system, which can be used for a brace according to the present invention. Prior art patents are cited in the '282 patent, which may describe other types of interlocking mechanisms. A snap fastener such as described in U.S. Pat. No. 2,397,801, issued to Mitchell, is another type of interlocking mechanism that can be used in making a brace according to the present invention.

(19) A brace according to the present invention is an assembly of spacers connected together by an interlocking mechanism. The brace has been described for use in a horizontal position with a clip for attachment to a toilet tank. A plate with an adhesive layer instead of the U-shaped clip may make the brace useful in other applications for bracing an object against a structure, such as a wall. A plate and a mechanical fastener such as one or more wood or machine screws is another way of attaching the brace to a thing that needs to be supported or braced. A brace according to the present invention can also be used in a vertical position. One application is the leveling and stabilization of chairs and tables on an uneven floor. Instead of the U-shaped clip 22, the stud 24 and the nut 26 in FIG. 3, one could use a plate with an adhesive layer on one side and an interlocking mechanism on the other side. The spacers can be much thinner, since a gap distance may be less than one-half of an inch or less than 1.5 cm, but can nevertheless have an interlocking mechanism for assembling a combination that has a desired combined length. Vertical applications include support for tables, chairs, shelving units, cabinets, furniture, laboratory equipment, shop equipment, tools, machines, tripods, stands and scaffolding. It may he desirable to use a material of construction that is more compressible or more resilient in applications as vertical spacers than in a horizontal application. A tank brace according to the present invention is preferably made of a generally rigid, but not brittle, thermoplastic polymeric material, while a vertical spacer may be made of a semi-rigid thermoplastic or a semi-rigid polymeric foam that has greater compressibility than is used in a horizontal application. However, the selection of a material depends on the application, and a metal could be used instead of a plastic material, or an entirely different material could be used. The brace has been illustrated as having a generally cylindrical shape with a plurality of ridges and valleys spaced around an outer circumference, but it is not necessary that the brace have a cylindrical shape or that it have the ridges or valleys. The cross-section of the brace could have a different shape such as rectangular, square or hexagonal, and rather than ridges or valleys for making the outer surface easier to grip, the outer surface could be a knurled surface.
