The present disclosure relates to pivoting metal connection hardware for rigidly joining wood or metal structural framing members but with framing members being pivotable allowing selective displacement of framing members to variable positions.
Existing pivoting hardware includes door hardware, revolving doors, rotating door structures, rotatable structures, revolving wall systems and panels, revolving modules and packages, furniture systems, hinge assemblies, and hinged joints for structural frame systems. In addition, rigid connection hardware is available in the form of rigid intersection connectors.
Concepts of pivoting hardware are frequently depicted in large complicated systems that are very expensive, are not premanufactured, nor readily available to the public for purchase, and require a high level of knowledge and ability of a person skilled in the art to install these systems.
A variety of pivoting hardware is presented in the prior art:

Although the prior art pivot hardware rotates doors, panels, systems, modules, and structures, none of the prior art pivot hardware allows a simple and practical way of connecting conventional wood or metal structural framing members to allow pivotable selective displacement of desired framing members to variable positions.
The prior art pivot hardware fails to allow flexibility for the hardware to be used by a person skilled in the art of structural framing to incorporate spinning or rotating framing members in a variety of applications due to the inflexibility of the prior art to be used in such a manner other than specifically taught.
The present disclosure is directed to an improved, practical and flexible spin hardware designed for mass production for simple and cost-efficient incorporation into residential or commercial structural framing systems.
The improved spin hardware supports functional uses of rotating structural framing and has a construction compatible with heavy dead and live design loads required in modern building construction and by building codes.
The simple design of the improved spin hardware supports a use by “do-it-yourself” handyman/homeowners and not just persons skilled in the art of building construction, specifically structural framing. The use of any of the pivot hardware prior art by a “do-it-yourself” handyman/homeowner in a manner for the intended use of the improved spin hardware would be non-obvious.
The improved spin hardware is intended to be readily available and sold to the public as “off-the-shelf” hardware, similar to door hinges and other standard building hardware, at local hardware stores.
Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

The present disclosure provides metal connection spin hardware which allows rigid structural framing members to pivot within other rigid structural framing members. Referring now to the figures, where numerals represent various elements of the present disclosure, the spin hardware is generally illustrated in
The spin hardware 10 generally consists of precision welded bottom brackets 11, top brackets 12 and counter brackets 12A, where a counter or credenza will be used. All bracket components may be high grade steel. The spin hardware 10 attaches to structural framing members 13 which allow desired portions of the structural framing members 14 to rotate 15.
The bottom bracket assembly 11 is generally illustrated in
A front elevation view of the bottom bracket assembly 11 is generally illustrated in
A front elevation of the top bracket assembly 12 is generally illustrated in
A front elevation of the top bracket assembly 12 according to another embodiment is illustrated in
The spacer sleeve 26A also controls and minimizes the slight air space/clearance 27 between the inside surface of the top-top pipe sleeve 26 and the outside surface of the top-bottom pipe sleeve of top-bottom bracket 24, as shown in
The spacer sleeve 26A may be constructed of stainless steel and/or another material. The thicknesses of the spacer sleeves 26A are configured to minimize the slight air space/clearance between the pipe sleeves of the bracket assemblies, optimizing the spin/rotation movement of the brackets. The thicknesses of the spacer sleeves can be adjusted for differing pipe sleeve sizes for brackets manufactured in a plurality of sizes configured to support increased dead and live loads.
An end elevation view of the top bracket assembly 12 is generally illustrated in
A front elevation view of the bottom bracket assembly 11 with a spacer sleeve 26A according to one embodiment is generally illustrated in
Both the belled flange 19 and welded washer 19A correspond to bearing surfaces that provide the same function of bearing on top of a pre-manufactured industrial bearing 20. Specifically, the belled flange 19 increases the horizontal surface area at the bottom of the pipe sleeve 18 so that it is close to matching the top horizontal surface area of the pre-manufactured industrial bearing 20, allowing the substantial vertical dead and live loads to be uniformly spread over the largest possible horizontal surface area at the top of the bearing 20, allowing the bearing 20 to function smoothly. A large washer 19A with a horizontal surface area sized to match the belled flange 19, welded to the bottom of the pipe sleeve, may perform the same function as the belled flange 19.
A specific tool may be used to shape the end of pipe to have a belled flange 19. Not all precision welding and steel fabrication shops have this specific tool, limiting the number of manufacturers that can produce a belled flange 19 component. The use of a welded washer 19A in lieu of a belled flange 19 may increase the number of manufacturers that can produce the bottom-top bracket 17 component. The diameter of the outer vertical edge of a welded washer 19A can be increased in size to match the outer diameter of larger pre-manufactured industrial bearings 20, whereas the outer diameter of a belled flange 19 may be limited to its size.
The welded washer 19A may be comprised of the same high strength weldable material as the bracket assembly to which it is welded. In one example, the welded washer is ¼″ thick, but the welded washer 19A can be manufactured in a plurality of sizes configured to support increased dead and live loads. The welded washer 19A may be round, with an outside diameter to closely match the outside diameter of the pre-manufactured industrial bearing 20. The welded washer 19A has a hole through its entire thickness, centered within its outer diameter.

A front elevation view of the bottom-top bracket 17 is illustrated in
In another example, the hole in the welded washer 36A is slightly larger than the outside diameter of the vertical pipe 33. The bottom of the vertical pipe 33 fits through the hole in the welded washer 36A so that the surface of the bottom of the vertical pipe 33 aligns with the surface of the bottom of the welded washer 36A. In this example, a grounded smooth continuous weld may be made at the bottom of the welded washer 36A that welds the inside edge of the hole in the welded washer 36A to the outside edge of the vertical pipe 33. A small fillet weld may be made at the top of the welded washer 36A and the outside edge of the vertical pipe 33.

The embodiment of installing spin hardware 10 is illustrated in
The pre-manufactured spin hardware 10 may be distributed in pre-assembled kits. The top & bottom bracket kit would include the top bracket assembly 12, bottom bracket assembly 11, one pre-packaged industrial bearing 20, and all of the associated screws 22 and washers necessary to install the top & bottom brackets, including installation instructions. The counter bracket 12A kit would include four counter brackets 12A and all of the associated screws 22 and washers necessary to install the counter brackets 12A, including installation instructions.
The spin hardware 10 may be installed by a contractor, a carpenter, a millwork/cabinet installer, or an average “do-it-yourself” homeowner with the proper tools and abilities to follow the spin hardware instructions.
A front elevation view of the embodiment of installing spin hardware 10 is illustrated in
The industrial bearing 20 is placed over the pipe 28 of the bottom-bottom bracket 16. The bottom-bottom bracket 16 is placed under the bottom-top bracket 17 and is lifted and held in place so the pipe 28 of the bottom-bottom bracket 16 is inside of the pipe sleeve 33 of the bottom-top bracket 17, with the top surface of the industrial bearing 20 hitting the bottom surface of the belled flange 36 or welded washer 36A. The pre-framed component 50 is slid into the pre-framed rough opening 51. The top-top bracket 25 is attached to the bottom of the pre-framed rough opening component 51 after locating the center of the top-top bracket 25 on the vertical rotating axis 49 of the bottom-top bracket 17. The bottom-bottom bracket 16 is attached to the top of the pre-framed rough opening 51 after locating the center of the bottom-bottom bracket 16 on the vertical rotating axis 49 of the bottom-top bracket 17.
The counter brackets 12A are installed at a desired height from a horizontal floor plane 52 by attaching each individual counter bracket 12A to an individual vertical framing member 13 of a pre-framed component 50 such as a wall. The vertical plate 45 of a counter bracket 12A is attached securely into a vertical wood framing member 13 so that the vertical plate 45 is plumb and the horizontal tube 44 is perpendicular to the vertical wood framing member 13. After enough counter brackets 12A required to support the countertop-credenza 53 have been installed to the pre-framed wood component 50, such as a wall, the countertop/credenza 53 can be placed on top of the horizontal tubes 44. Once the countertop/credenza 53 is located as desired, it is attached to the counter brackets 12A by screwing wood screws 22 through the pre-drilled holes 48 in the horizontal tubes 44 into the bottom of the countertop/credenza 53.
An average “do-it-yourself” homeowner (or contractor, carpenter, millwork/cabinet installer, etc.) could purchase pre-manufactured spin hardware 10 in pre-assembled kits from easy to purchase locations (local hardware stores or the internet) and could install spin hardware 10 as indicated on
