## Title
Support assembly

## Abstract

A support assembly and a method of assembling the support assembly that includes a structural member that is delimited by a first end and a second end with a first end cap configured to be arranged within the first end of the structural member and a second end configured to be arranged within the second end of the structural member to mount the structural member to a structure. The support assembly allows for forces to be applied in all directions without causing rotation or disengagement of the support assembly from a mounting structure.

## Background
FIELD OF THE INVENTION
The present invention relates generally to a supporting structure and more particularly to a support assembly that is mountable between two converging structures.
BACKGROUND OF THE INVENTION
Support assemblies and more specifically support assemblies that are mountable in a corner of a room between two converging walls are known. These support assemblies, such as foot rests, grab bars, and shelving systems are commonly used, for example, in household showers, locker rooms, spas and the like. However, existing support assemblies do not allow for any significant force to be applied thereon without the support assembly rotating and/or becoming disengaged from a fixed position. As such, an individual can be severely injured due to the limited force that can safely sustained by known support assemblies.
SUMMARY OF THE INVENTION
The present invention is directed to a support assembly that allows for significant forces to be applied in all directions without causing rotation or disengagement of the support assembly from a mounting structure. This is because, as will be described in more detail below, the end caps of the support assembly are not mounted in parallel to each other. As a result, the rotational axes of the end caps contrast each other and in turn stabilize a structure extending between and from the end caps. Moment forces only exist in the area of the structure that exceeds the axes of the end caps. As such, the moment forces are minimized and the torsion forces are negated by opposing each other resulting in an assembly that is stable and does not rotate upon a force being applied thereto.
In an embodiment, the present invention is directed to a support assembly that comprises a structure that has an outer surface and inner surface and that is delimited by a first and second end, a first end cap that includes a first body which has a first element (e.g., trapezoidal, triangular) that extends therefrom and that is configured to be arranged within the first end of the structure and a second end cap that includes a second body which has a second element (e.g., trapezoidal, triangular) that extends therefrom and that is configured to be arranged within the second end of the structure. In an embodiment, the structure can be a tubular member, a cantilevered plate or any other structure that extends between the end caps.
In an embodiment, the first and second ends of the structure lie in planes such that a first plane extends along the first end of the structure and a second plane extends along the second end of the structure to converge and intersect each other at a line centrally located between the ends of the structure. In an embodiment, the planes in which the first and second end of the structure lie are angled at approximately 45 degrees with respect to the axis of the structure so that the planes meet at angles of approximately 90 degrees.
In an embodiment, the first end cap is sized to encompass the first end of the structure and the second end cap is sized to encompass the second end of the structure. In an embodiment, the first and second end caps each have a body that is substantially ovoid to encompass the first and second end that are also substantially ovoid.
In an embodiment, the first end cap includes an opening extending through the first body and the first trapezoidal element and the second end cap includes an opening extending through the second body and the second trapezoidal element of the second end cap.
In an embodiment, the first trapezoidal element can substantially encompass a longitudinal diameter of the first body of the first end cap and the second trapezoidal element can substantially encompass a longitudinal diameter of the second body of the second end cap.
In an embodiment, the support assembly can further comprise a first insert fixed within the first end of the structure that includes a first slot configured to receive the first trapezoidal element and a second insert fixed within the second end of the structure that includes a second slot configured to receive the second trapezoidal element.
In an embodiment, the first insert and the second insert can include a base, a first projection extending from the base that has an outer surface which is contoured to be contactable with the inner surface of the structure and a second projection spaced from the first projection by the first slot extending from the base that has an outer surface that is contoured to be contactable with the inner surface of the body of the structure. In an embodiment, the first and second projections of the first and second inserts can each extend from the base of the insert at an angle that is substantially similar to the angle of the first end of the structure. In an embodiment, the angle at which the ends and projections extend is about 45 degrees.
In an embodiment, the support assembly can include a first opening extending between the outer and inner surface near the first end of the structure and a second opening extending between the outer and inner surface near the second end of the structure, a first hole extending through one of the first projection and the second projection of the first insert with the first insert adaptable such that the first hole is in alignment with the first opening and a second hole extending through one of the first projection and the second projection of the second insert with the second insert adaptable such that the second hole is in alignment with the second opening.
In an embodiment, the support assembly can include a first fastener extending through the first opening in the structure and the first hole in the first insert to fix the first end cap within the structure and a second fastener extending through the second opening in the structure and the second hole in the second insert to fix the second end cap within the structure. In an embodiment, the first fastener and the second fastener are each set screws.
In an embodiment, the structure, the first end cap and the second end cap can each be comprised of a metal, such as stainless steel and at least a region of the outer surface of the body of the tubular member can have an anti-slip surface.
In an embodiment, the present invention is directed to a method of assembling a corner support assembly. The method comprises the steps of providing a structural member that has an outer surface and an inner surface and that is delimited by a first end and a second end, a first end cap that includes a first body having a first surface and a second surface with a first trapezoidal element that is configured to be arranged within the first end of the structural member extending from the first body and a second end cap including a second body that has first surface and a second surface with a second trapezoidal element that is configured to be arranged within the second end of the structural member extending from the second body, fastening the first end cap to a first structure and the second end cap to a second structure such that the first trapezoidal element and the second trapezoidal element project from the first structure and second structure, respectively, orientating the first end of the structural member to encompass the first trapezoidal element and the second end of the structural member to encompass the second trapezoidal element and fixing the structural member to the first end cap and the second end cap.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
FIGS. 1-18 illustrate an embodiment of a support assembly, which is designated hereinafter by reference numeral 10. As will be described in more detail below, in general the support assembly 10 includes a substantially tubular member 12, a first insert 14, a second insert 16, a first end cap 18, a second end cap 20 and a plurality of fasteners 22A, 22B. The support assembly 10 can be used, for example, as a foot rest, a grab bar, a mounting structure in conjunction with bath accessories or as support for any structure (e.g., shelving). Although the support assembly 10 is shown as including a tubular member 12 that is substantially cylindrical, the tubular member 12 can be any supporting body of any shape that extends between at least a first end cap and a second end cap. For example, as shown in an embodiment in FIGS. 16-18, the support assembly includes a shelving support 100 that includes a cantilevered plate attached (e.g., welded) to a tubular member.
As shown in an embodiment in FIGS. 1-15, the tubular member 12 is an elongated hollow cylindrical structure that includes an outer surface 24 and an inner surface 26 and that is delimited between a first end 28 and a second end 30. The first end 28 and the second end 30 of the tubular member 12 are both angled such that a first plane extending along the first end 28 and a second plane extending along the second end 30 converge and intersect each other at a central point between the ends 28, 30 of the tubular member 12. As such, in an embodiment, the first angled end 28 and the second angled end 30 allow for the support assembly 10 to be mounted between two converging surfaces 32, 34 (See FIGS. 14 and 15) that are substantially perpendicular to each other. In an embodiment, the first end 28 and the second end 30 are both angled at approximately about 45 degrees.
As will be explained in more detail below, as shown in FIGS. 1, 2 and 5-8, a first opening 36 extends through the tubular member 12 substantially transverse to and near the first end 28 of the tubular member 12 and a second opening 38 extends through the tubular member 12 substantially transverse to and near the second end 30 of the tubular member 12.
As shown in an embodiment in FIG. 2, the first end 28 and the second end 30 of the tubular member 12 are substantially ovoid. In an embodiment, the tubular member 12 is formed from metal such as stainless steel (e.g., 18/8 (304) stainless steel). However, the tubular member 12 can be formed from any material that is known or may become known that allows for sustaining a force to be applied thereto. As can be seen in an embodiment in FIG. 1, an anti-slip grip 40 can extend about at least a portion of the outer surface 24 of the tubular member 12.
As depicted, for example, in FIG. 2, the first insert 14 is fixed within the first end 28 of the tubular member 12 and the second insert 16 is fixed within the second end 30 of the tubular member 12. The first insert 14 and second insert 16 can be fixed within the tubular member by press fit, welding, bonding (e.g. using an adhesive), fastening or the like.
In an embodiment, the first insert 14 and the second insert 16, respectively include a body 42A, 42B that has a base 44A, 44B, a first projection 46A, 46B that extends from the base 44A, 44B in a first direction and a second projection 48A, 48B that is spaced from the first projection 46A, 46B and extends from the base 44A, 44B in the first direction as well. Both the first projection 46A, 46B and the second projection 48A, 48B include an outer surface 50A, 50B, 52A, 52B, respectively, that is contoured to be contactable with the inner surface 26 of the tubular member 12 and an inner surface 54A, 54B, 56A, 56B that extends substantially linearly from the base 44A, 44B of the first and second insert 14, 16, respectively. In an embodiment, the outer surfaces 50A, 50B, 52A, 52B of the inserts 14, 16 are substantially ovoid. As can be seen in FIG. 2, the first and second projections 46A, 46B, 48A, 48B extend at an angle from the base 44A, 44B that is substantially the same as the angle of the first end 28 of the tubular member 12. As such, the inner surfaces 54A, 54B, 56A, 56B of the projections 46A, 46B, 48A, 48B are substantially triangular. In an embodiment as shown in FIG. 7, the inner surfaces 54A, 54B, 56A, 56B of the first and second projection 46A, 46B, 48A, 48B each form a right triangle. However, the inserts 14, 16 can be configured to be any shape and/or size to accommodate the end caps 18, 20.
As shown in an embodiment in FIG. 2, a first hole 58 extends through one of the first projection 46A and the second projection 48A of the first insert 14 with the first insert 14 adaptable such that the first hole 58 is in alignment with the first opening 36 formed in the tubular member 12. As shown in FIGS. 2 and 7, a second hole 60 extends through one of the first projection 46B and the second projection 48B of the second insert 16, which is adaptable so that the second hole 60 is in alignment with the second opening 38. In an embodiment, the first hole 58 can be formed in both the first projection 46A and the second projection 48A of the first insert 14 and the second hole 60 can be formed in both the first projection 46B and the second projection 48B of the second insert 16.
FIGS. 9-13 illustrate an embodiment the first end cap 18 and the second end cap 20 that are configured to be arranged within the first insert 14 and the second insert 16, respectively, to fix the tubular member 12 to a structure. The first end cap 18 and the second end cap 20, respectively include a body 62A, 62B that has a first surface 64A, 64B and a second surface 66A, 66B, which opposes the first surface 64A, 64B. As shown in an embodiment in FIGS. 9-11, the body 62A, 62B of the first and second end cap 18, 20, respectively, is substantially ovoid. A trapezoidal element 68A, 68B extends, respectively, from the first surface 64A, 64B of the body 62A, 62B of the end caps 18, 20. In an embodiment, the body 62A, 62B is substantially ovoid. However, the end caps can be of any shape and the elements that extend from the end caps can also be of any shape that substantially matches the opening within the inserts 12, 14.
In an embodiment, the trapezoidal element 68A, 68B includes a first base 70A, 70B that substantially extends along longitudinal diameter from the first surface 64A, 64B of the body 62A, 62B of the end caps 18, 20, a first sidewall 72A, 72B extends at or near a first end 74A, 74B of the first base 70A, 70B at an angle, a second sidewall 76A, 76B extends at or near a second end 78A, 78B of the first base 70A, 70B at an angle and a second base 80A, 80B that is spaced from and substantially parallel to the first base 70A, 70B and that extends between the first sidewall 72A, 72B and the second sidewall 76A, 76B. With the trapezoidal element 68A, 68B encompassing the end caps 18, 20 and interacting with the inserts 14, 16, respectively, rotational forces are substantially mitigated.
In an embodiment, the trapezoidal element 68A, 68B includes an opening 82A, 82B through which a fastener (e.g., a screw) can extend to fix the trapezoidal element 68A, 68B to a structure (see e.g., FIGS. 14 and 15). As can be seen in an embodiment in FIGS. 9-11, the opening 82A, 82B extends centrally from the second surface 66A, 66B of the body 62A, 62B of each of the end caps 18, 20 through the first base 70A, 70B and second base 80A, 80B of the trapezoidal element 68A, 68B. The trapezoidal element 68A, 68B herein allow room for the head of a mounting screw.
As shown in FIG. 14, upon fastening the end caps 18, 20 to a structure, the tubular element 12 can be slide over the trapezoidal elements 68A, 68B, arranging the first trapezoidal element 68A within a slot 84 of the first insert 14 formed between the inner surface 54A, 56A of the first and second projections 46A, 48A and the second trapezoidal element 68B within the slot 86B formed between the inner surface 54B, 56B of the first and second projections 46B, 48B of the second insert 16. A first fastener 22A can be inserted through the first opening 36 in the tubular member 12 and the first hole 58 of the first insert 14 and contact the trapezoidal element 68aA to fix the first end cap 18 within the tubular member 12 and a second fastener 22B to be inserted through the second opening 38 in the tubular member 12 and the second hole 60 of the second insert 48 and contact the trapezoidal element 68B to fix the second end cap 20 within the tubular member 12. In an embodiment, the first hole 58 of the first insert 14 and the second hole 60 of the second insert 16 include threading (not shown) extending about each opening 58, 60 and the fastener 22A, 22B is a set screw that fixes the end caps 18, 20 within the inserts 14, 16 and to the tubular member 12.
Because the end caps 18, 20 are not mounted in parallel to each other the rotational axes of the end caps 20, 22 contrast each other, the rotational axes of the end caps 18, 20 contrast each other and in turn stabilize the tubular element. The moment forces only exist in the area of the tubular element 12 that exceeds the axes of the end caps 18, 20. As such, the moment forces are minimized and the torsion forces are negated by opposing each other resulting in an assembly that is stable and does not rotate upon a force being applied thereto.
The foregoing description and accompanying drawings illustrate the principles, exemplary embodiments, and modes of operation of the invention. However, the invention should not be construed as being limited to the particular embodiments discussed above. Additional variations of the embodiments discussed above will be appreciated by those skilled in the art and the above-described embodiments should be regarded as illustrative rather than restrictive. Accordingly, it should be appreciated that variations to those embodiments can be made by those skilled in the art without departing from the scope of the invention.
