Description of Exemplary Embodiments [46] The construction industry has utilized many types of fixed support hangers to support joists or other types of structural members, light metal framing hangers or joist hangers being perhaps the most common example. However, fixed support hangers do not allow for relative movement between the attached structural members. In fact, support hangers are often designed to minimize or eliminate relative motion between the attached structural members.
[47] For example, a typical joist hanger comprises a rigid frame for securing a joist to a supporting member; once the joist hanger has been secured to both the joist and the supporting member (typically by nailing), relative motion between the joist and the supporting member is prevented. While some support hangers provide for a limited degree of relative movement between a joist and a supporting member during installation (e.g. to adjust the slope and/or skew between the joist and the structural member), these support hangers are designed to provide a fixed, rigid connection following installation.
[48] However, in some situations it may be desirable to provide a pivoting connection to allow relative movement between a joist and a supporting member following installation.
[49] For example, in regions with soil susceptible to frost heaving, it may be desirable to provide a continuously pivoting connection between a fixed structure such as a house and the floor joists of an attached structure such as a deck, awning, pergola or dock, so that a support pier for a distal end of the attached structure (i.e. distal to the connection between the fixed structure and the attached structure) can be vertically displaced relative to the fixed structure without significant torque being transferred to the fixed structure.
[50] To prevent structural damage resulting from frost heaving, foundations typically include footings located below the frost line. In many jurisdictions, local building codes provide minimum requirements for the design and installation of foundations in frost susceptible soil; these minimum requirements are generally more onerous than for foundations in non-frost susceptible soil.
[51] To reduce the potential impact of frost heave, it is common practice that when attaching a new structure, such as a deck, to a structure comprising a frost heave-resistant foundation, such as a house, using a rigid connection (e.g. a connection using rigid support hangers), the foundation for the new structure is also provided with a frost heave-resistant foundation. This may be a building code requirement in some jurisdictions. For example, if a deck is attached to a house - either as part of a new house construction, or as a subsequent addition - all of the deck supports may require frost heave-resistant piers and footings. In most cases, installing frost heave-resistant footings adds significant complexity and cost to the installation of a deck.
[52] If distal deck footings are not provided with frost heave-resistant foundations, the relative vertical motion between these deck footings and the structure to which the deck is attached (due to frost heave) may impart a significant torque to the rigid connection between the deck joists and the structure to which the deck is attached. This torque may cause distress to the fixed structure and/or the deck.
[53] In the past, this issue was addressed in one of two ways: either i) the distal deck supports were provided with frost heave-resistant footings, often increasing the cost of installing the deck; or ii) the deck was not attached to the house at all.
While providing a `free floating' deck adjacent to, but not attached to, a house may eliminate the requirement for frost heave-resistant footings for the deck supports, such a deck may not provide an aesthetically pleasing interface between the deck and the house.
[54] Also, providing a `free floating' deck adjacent to, but not attached to, a house typically requires additional support piers and columns to be installed to support the portion of the deck proximate to the house, adding expense in material and installation costs. Also, support piers located adjacent to the foundation of a house may experience different degrees of frost heave relative to support piers located for a distal end of the attached deck (i.e. distal to the connection between the house and the deck).
For example, support piers located adjacent to the foundation of the house may not rise as much due to frost heave relative to deck supports located away from the house.
In this case, it is possible that the deck may pivot or jam against the house, which may cause distress to the house and/or the deck.
[55] In contrast, unlike typical support hangers, which provide a fixed/static connection between a joist and a fixed structure after installation, embodiments disclosed herein provide a pivotal coupling between a joist and a fixed structure when in use, so that when the joist is coupled to the fixed structure via the support hanger assembly, the joist can be pivoted relative to the fixed structure without significant torque being transferred to the fixed structure.
[56] By providing a pivotal coupling, relative movement between a joist and a supporting member may be accommodated after installation. For example, by securing the joists of a deck to a house using one or more support hanger assemblies as disclosed herein, the requirement to provide frost heave-resistant footings for distal deck supports may be eliminated. In this case, the pivotal coupling may accommodate distal deck supports that `float' up and down due to frost heaving, without causing distress to the deck and/or the fixed structure. This may greatly simplify and/or reduce the cost of installing decks in regions with soil susceptible to frost heaving.
[57] Aspects and features of various embodiments will be described in greater detail below. Embodiments of the present application provide support hangers and methods for pivotally coupling a joist to a fixed structure. In order to aid in the understanding of the general methods, specific embodiments are described below as an example of the general method; it is to be understood that alternate embodiments are feasible.
[58] Referring first to Figures 1 A-1 C, support hanger assembly 100 includes joist bracket 110 and support bracket 120. At least one joist connector bore 116 extends through joist bracket 110, and support connector bores 126 extend through each of at least two flanges 124 of the support bracket 120. In use, joist bracket 110 is positioned relative to support bracket 120 so that the at least one joist connector bore 116 and the support connector bores 126 are aligned, and connecting member 130 is inserted through joist connector bores 116 and support connector bores 126 to pivotally couple joist bracket 110 to support bracket 120. That is, when coupled by connecting member 130, joist bracket 110 is able to pivot back and forth about connecting member relative to support bracket 120.
[59] As shown in Figure 2, when support bracket 120 is mounted to a fixed structure 400 such that the axis of rotation provided by connecting member 130 is generally horizontal, a distal end of joist 500 - fastened to joist bracket 110 - may be raised or lowered in a vertical direction relative to fixed structure 400 without significant torque being transferred to fixed structure 400 via support assembly 100. In general, support bracket 120 permits movement of the joist bracket in a direction generally perpendicular to the direction of the connection member.
[60] For example, if the fixed structure is a ribbon joist attached to a house having a foundation designed to minimize or eliminate vertical displacement due to frost heave, connecting the floor joists of a deck using one or more support assemblies 100 may obviate the need to provide foundations designed to minimize or eliminate vertical displacement due to frost heave for one or more distal deck supports, as any differential vertical movement between distal ends of the deck joists relative to the ribbon joist will result in the deck joists pivoting in the support bracket without significant torque being transferred to the fixed structure. As a result, the one or more distal deck supports may not require piers connected to footings installed below the frost line.
[61] As shown in Figures 3A-3C, joist bracket 110 may comprise joist bracket base 112 and a pair of joist plates 114 extending from the joist bracket base 112.
That is, the joist bracket base 112 and a pair of joist plates 114 may form a substantially U-shaped joist bracket 110. Such a U-shaped joist bracket may be dimensioned to receive an end of a typical 2 x 8 or 2 x 10 floor joist.
[62] For example, the joist bracket base 112 may be wide enough to provide a clearance of 1 5/8 inches between inner faces of joist plates 114, and joist plates 114 may extend approximately 7 inches from the joist bracket base 112. In some embodiments, joist bracket base 112 may be 2 inches by 2 5/8 inches deep (i.e.
joist plates 114 may be approximately 7 inches tall by 2 5/8 inches deep). Those skilled in the art will understand that any suitable dimensions may be selected based on loading or other requirements of a particular application.
[63] In some embodiments, as shown in Figure 3B, joist bracket 110 may also include bearing 117, and joist connector bore 116 may be an inner bore of this bearing. This may decrease the friction between joist bracket 110 and connecting member 130 as joist bracket 110 pivots relative to support bracket 120.
[64] In some embodiments, bearing 117 may be a spherical bearing. By providing a spherical bearing, joist bracket 110 may more readily accommodate one or more components of rotation (e.g. yaw or roll) in addition to pivoting (e.g.
pitching) about the axis of connecting member 130.
[65] In addition to joist connector bore 116, joist plates 114 may also have one or more fastener bores 118 to accommodate mechanical fasteners (e.g. nails, screws) for securing the joist bracket 110 to joist 500. Any suitable size of fastener bore may be provided. For example, 3/8 inch diameter bores may be provided, for accommodating 2"
to 3" lag screws.
[66] Fastener bores 118 are preferably spaced apart along the joist plate 114, and in embodiments where joist bracket 110 comprises more than one joist plate, fastener bores 118 are preferably offset such that there is no interference between fasteners inserted through opposing joist plates. Although three bores 118 are illustrated for each joist plate 114, those skilled in the art will understand that any suitable number of bores 118 may be provided.
[67] As shown in Figures 3A-3C, the joist bracket base 112 and a pair of joist plates 114 may form a substantially U-shaped joist bracket 110. In other embodiments, only one joist plate 114 may extend from the joist bracket base 112, forming a generally L-shaped joist bracket 110, as shown in Figures 4A-4C. Alternatively, joist bracket 110 may consist solely of joist plate 114 (not shown).
[68] As shown in Figures 5A-5C, support bracket 120 may comprise support bracket base 122 and a pair of flanges 124 extending from the support bracket base.
That is, support bracket base 122 and flanges 124 may form a substantially C-shaped support bracket 120. Support connector bore 126, dimensioned to receive connecting member 130, extends through each flange 124. Such a C-shaped joist bracket may be dimensioned such that the flanges 124 are spaced apart to receive at least a portion of joist bracket 110 and/or at least a portion of an end of joist 500 therebetween.
[69] For example, the support bracket base 122 may be approximately 2 1/2 inches wide by 7 inches tall, and flanges 124 may extend approximately 31/2 inches from the support bracket base 122 (i.e. flanges 124 may be approximately 7 inches tall by 3 1/2 inches deep). Those skilled in the art will understand that any suitable dimensions may be selected based on loading or other requirements of a particular application.
[70] Support bracket base 122 may have one or more fastener bores 128 to accommodate mechanical fasteners (e.g. nails, screws) for securing the support bracket 120 to fixed structure 400. Any suitable size of fastener bore may be provided. For example, 7/16 inch diameter bores may be provided, for accommodating standard inch joist nails. Fastener bores 128 are preferably spaced apart along the support bracket base 122. Although two bores 128 are illustrated, those skilled in the art will understand that any suitable number of bores 128 may be provided.
[71] As shown in Figures 5A-5C, the support bracket base 122 and at least two flanges 124 may form a substantially C-shaped support bracket 120. In other embodiments, only one flange 124 may extend from the support bracket base 122, forming a generally L-shaped support bracket 120, as shown in Figures 6A-6C.
[72] Connecting member 130 may be dimensioned to be received in joist connector bore(s) 116 and support connector bore(s) 126 while allowing joist bracket 110 to pivot back and forth relative to support bracket 120 without significant torque being transferred via support assembly 100.
[73] In some embodiments, connecting member 130 may comprise a bolt with a flared head at one end and threads disposed on the other end for receiving a complementary nut, so that when the threaded end of the bolt is inserted through the joist connector bore(s) 116 and support connector bore(s) 126 and the complementary nut threaded onto the threaded end of the bolt, the flared head and the nut act to retain the connecting member 130 in the joist connector bore(s) 116 and support connector bore(s) 126.

[80] In an alternative embodiment shown in Figures 8A-8B, support hanger assembly 300 includes joist bracket 310 and support bracket 320. Joist connector ball extends from joist bracket base 312, and a portion of a surface 325 of each flange 324 cooperatively defines a support connector socket 326 of support bracket 320.
In use, joist connector ball 316 is disposed within support connector socket 326 so that joist connector ball 316 is pivotally coupled to support bracket 320. That is, a joist 500 secured to joist bracket 310 is able to pivot back and forth about more than one axis relative to support bracket 320.
[81] Joist bracket 310 may comprise joist bracket base 312 and a pair of joist plates 314 extending from the joist bracket base 312. That is, the joist bracket base 312 and joist plates 114 may form a substantially U-shaped bracket, preferably dimensioned to receive an end of a typical 2 x 8 or 2 x 10 floor joist. Joist plates 314 may have one or more fastener bores 318 to accommodate mechanical fasteners (e.g. nails, screws) for securing the joist bracket 310 to joist 500. Any suitable size of fastener bore may be provided.
[82] Support bracket 320 may comprise support bracket base 322 and a pair of flanges 324 extending from the support bracket base. That is, support bracket base 322 and flanges 324 may form a substantially C-shaped support bracket 320.
Complementary surfaces 325, dimensioned to cooperatively define support connector socket 326 to receive joist connector ball 316, are provided on each flange 324. Support bracket base 322 may have one or more fastener bores 328 to accommodate mechanical fasteners (e.g. nails, screws) for securing the support bracket 320 to fixed structure 400. Any suitable size of fastener bore may be provided.
[83] In some embodiments, flanges 324 may be sufficiently flexible to allow joist connector ball 316 to be inserted into support connector socket 326 after support bracket 320 has been mounted to fixed structure 400. As shown in Figures 8C
and 8D, flanges 324 may also include one or more spacer bores 350. Spacer bores 350 are sized to accommodate a spacer fastener360 (such as a bolt or other suitable mechanical fastener) that is positioned through spacer bores 350 and a spacer 355. In use, after joist connector ball 316 has been inserted into support connector socket 326, one or more spacers 355 are aligned with one or more spacer bores 350, and spacer fastener(s) 360 are disposed through spacer 355 and spacer bores 350 and secured in position, for example using nuts and/or washers. By providing spacers of a predetermined length, the distance between flanges 326 (and therefore the dimensions of support connector socket 326) can be controlled, providing a coupling between joist bracket 310 and support bracket 320 that is neither too loose nor too tight.
[84] As shown in Figure 9, when support bracket 320 is mounted to fixed structure 400, a distal end of joist 500 fastened to joist bracket 310 may be raised or lowered in a vertical direction relative to fixed structure 400 and/or displaced in a horizontal direction without significant torque being transferred to fixed structure 400 via support assembly 300.
[85] As shown in Figures 10A-10C, in some embodiments joist bracket 310 may comprise an articulating joint, such as rose joint 370, instead of joist connector ball 316.
Rose joint 370 may include casing 372, ball swivel 374, and joist connector bore 376. In some embodiments, rose joint 370 comprises one or more joist plates (not shown).
Alternatively (or additionally), rose joint 370 may comprise screw 378. As shown in Figure 10D, in use screw 378 may be used to fasten joist bracket 310 to joist without the need for joist plates.
[86] To pivotally couple a joist to a fixed structure, typically one would first fasten joist bracket 110 to joist 500, preferably at an end of joist 500, and separately mount support bracket 120 to fixed structure 400. Alternatively, support bracket 120 may be mounted to fixed structure 400 before joist bracket 110 is fastened to joist 500.
[87] Once joist bracket 110 is fastened to joist 500 and support bracket 120 has been mounted to fixed structure 400, joist bracket 110 is positioned relative to support bracket 120 so that joist connector bore(s) 116 and support connector bore(s) 126 are axially aligned.
[88] Once joist connector bore(s) 116 and support connector bore(s) 126 are axially aligned, connecting member 130 is disposed through joist connector bore(s) 116 and support connector bore(s) 126 to pivotally couple the joist bracket 110 to the support bracket 120.
[89] The present invention has been described here by way of example only.
