DESCRIPTION OF THE DISCLOSURE

A staging bracket according to the present disclosure is a safe, adaptable, and easily deployed apparatus that may be combined with one or more staging brackets to create a staging system for the support of persons or materials while work is being done on a structure, e.g., roofing, siding, etc. The staging bracket has a modular design that simplifies installation, such that it can be readily attached to a roof or other support member of a structure by a single person, and facilitates the adjustable vertical positioning of people or materials along the walls of the structure. The staging bracket can be attached to any structural roofing member, including most any type of existing roofing material, e.g., shingle, standing seam, corrugated, etc., on new or existing roofs of any pitch and can be attached along either the eave or gable ends of the structure.

Turning now to the figures, FIG. 1 shows an exemplary staging bracket 100 according to an embodiment of the present disclosure. At a high level, staging bracket 100 includes a support platform 104, a wall engagement member 108, and a roof engagement member 112. These three components serve to provide a support surface for persons and/or materials when staging bracket 100 is in use, stabilize the staging bracket against the structure, and to attach staging bracket 100 to a structural member on the structure.

Support platform 104 provides a safe, supportive surface for people and/or materials when staging bracket 100 is installed above ground-level and when used with additional ones of the staging brackets. In an exemplary embodiment, support platform 104 includes a support deck 116, an outer rail 120, and an inner rail 124. Support deck 116 is generally sized and configured to support a portion of one or more planks (not shown in FIG. 1), on which persons or materials would rest when staging bracket 100 is in use. As shown in FIG. 1, support deck 116 is generally rectangular in shape having multiple support members 122, which provide support and stability for workers standing upon a plank. The length of support members 122 (122A-B) being generally sufficient to allow a plank to rest proximate the support members. In an alternative embodiment, support deck 116 may only have a single support member 122 (not shown) extending between outer rail 120 and inner rail 124.

Outer rail 120 and inner rail 124 are coupled to opposing sides 128, e.g., sides 128A-B, of support deck 116, with the outer rail and inner rail being substantially orthogonal to the support deck. Outer rail 120 is generally sized and configured to reduce the possibility that a person would fall from the elevated position of the staging by providing support for one or more brace members (FIG. 4) that reside above the plank. The overall longitudinal length of outer rail 120 may be adjustable by, for example, providing nested tubular structures (not shown) that can be adjusted in increments of for example, 1 inch.

In the embodiment shown in FIG. 1, outer rail 120 includes a plurality of brace holders 132. Brace holders 132 are sized and configured to receive brace members (shown in FIG. 4). For example, the brace members could be 2×4 boards and brace holders 132 could be sized and configured to support the 2×4 boards. Securing of the brace members to brace holders 132 can be accomplished by methods known in the art such as press fit or otherwise nailed or fastened through apertures, such as apertures 136, provided in the brace holders. The number, design, and configuration of brace holders 132 may vary according to safety requirements of the jurisdiction of use or the needs of the crew using staging bracket 100. For example, alternative brace holders 132 are shown in FIGS. 2 and 3.

In an exemplary embodiment, outer rail 120 also includes a shelf bracket 140. Shelf bracket 140 is sized and dimensioned to support an portion of a shelf (shown in FIG. 4). Shelf bracket 140 can include one or more shelf flanges 144 that assist in securing a shelf in position. In certain embodiments shelf bracket 140 can be integral with outer rail 120, or, and as shown in FIG. 1, can include a shelf adjuster 148 that is configured to mate with the outer rail 120 so as to allow for height adjustment of the shelf bracket. In an exemplary embodiment, shelf adjuster 148 is a tubular structure designed to nest within outer rail 120. In this embodiment, a plurality of apertures are provided in increments along the longitudinal axis of shelf adjuster 148 and at least one aperture is included with outer rail 120. A pin or bolt can be used to couple shelf adjuster 148 to outer rail 120 when their respective apertures align.

Inner rail 124 serves to connect support platform 104 to wall engagement member 108. In an exemplary embodiment, inner rail 124 extends orthogonally away from support deck 116 and is releasably coupled to wall engagement member 108 via a first receiver 152 and is releasably coupled to roof engagement member 112 via a second receiver 156. In this embodiment, first receiver 152 and second receiver 156 each include apertures for securing the components of staging bracket 100 together using pins or other connectors known in the art. Inner rail 124 can also include one or more brace holders 132 as needed or desired.

Wall engagement member 108 positions staging bracket 100 a suitable distance from the edge of the structure the staging bracket in an appropriate position for receiving people and or materials. In an exemplary embodiment, wall engagement member 108 includes an extendable wall tube 158 that has on its distal end a bumper 160. Wall tube 158 is sized and configured to slidably engage with first receiver 152 and to be connected thereto, such as by pins or other connectors through apertures in the wall tube and the first receiver. Bumper 160 rests against the structure when staging bracket 100 is installed. Bumper 160 can include a covering 164, such as a rubber membrane, that prevents marring or other types of deformation of the structure. Wall engagement member 108, via wall tube 158, can be adjusted (extended or retracted) so as to properly position stating bracket 100 and/or to avoid soffits or gutters if necessary. As shown in FIG. 1, wall engagement member 108 has a partially nested tubular construction that facilitates lengthening or shortening the wall engagement member in fixed increments, although other types of construction facilitate extension or retraction may be used. A pin (not shown) inserted into corresponding apertures in wall tube 158 and first receiver 152 may be used to fix the length of wall engagement member 108.

Roof engagement member 112 is coupled to outer rail 124 via second receiver 156 and is extendable, both horizontally and vertically, so as to facilitate attachment to various roof configurations and pitches. In an exemplary embodiment, roof engagement member 112 is composed of a plurality of at least partially nestable tubular structures that allow for expansion or retraction of the roof engagement member in the horizontal and vertical directions (relative to the ground when installed) at fixed intervals, e.g., 1 inch. For example, and as shown in FIG. 1, roof engagement member 112 may include a tubular structure 168 that allows for extension or retraction in the vertical direction, Additional tubular structures 168, such as 168A-B (shown in FIG. 2) or 168C (shown in FIG. 4), may be included to further extend. the vertical range of use of staging bracket 100. Tubular structure 168 may be connected to additional tubular structures or outer rail 120 using pins, spring-snaps, or other connectors known in the art.

In an alternative embodiment, roof engagement member 112 extends or retracts by rotating one portion of the roof engagement member relative to another portion of the roof engagement member (not shown). In another alternative embodiment, one or more additional portions of roof engagement member 112 may be coupled together using connectors or other coupling mechanisms known in the art (not shown).

Roof engagement member 112 includes a removable coupling 172. Removable coupling 172 facilitates secure, yet adjustable, attachment to the structure. As shown in FIG. 1, coupling 172 is a shingle coupling 174 that has an articulable flange 176 with a plurality of apertures 178 for receiving a corresponding respective number of fasteners (not shown). Articulable flange 176 can be rotated using a hinge, such as hinge 180, or can rotatable using other mechanisms known in the art. Other forms of coupling 172 configured for other roof structure members, e.g., different roofing materials, are discussed further below with reference to FIGS. 5A-5B.

Roof engagement member 112 may also include a cleat holder 184, which receives a cleat (shown in FIG. 4) that supports crew members when working further up the roof line of the structure.

In an exemplary embodiment, support platform 104, wall engagement member 108, and roof engagement member 112 are largely made from aluminum square tubing so that staging bracket 100 is light and durable, although other materials, such as square steel, or rounded tubing could be used.

FIG. 2 shows another exemplary embodiment of a staging bracket according to the present disclosure, staging bracket 200. While in many ways similar to staging bracket 100, staging bracket 200 includes a support platform 204, the configuration of which provides for variable width planks for supporting workers, while accommodating the need for staging bracket to be mountable around a soffit and/or gutter extending from the roof. In increased surface area for a plank is accomplished by providing a bump out 208, which undercuts a roof extension area 212. Bump out 208 is formed between a wall engagement member receiver 216 and a support deck 220.

Staging bracket 200 also includes an alternative embodiment of roof engagement member 112, roof engagement member 224. Roof engagement member 224 has a plurality of at least partially nestable tubular structures 168, tubular structures 168A-B, that allow for expansion or retraction of the roof engagement member in the vertical direction thereby allowing for staging bracket 200 to be placed at desired vertical positions along the structure to facilitate work such as painting or siding of the sides of the structure.

FIG. 3 shows an exploded view of another exemplary embodiment of a staging bracket, staging bracket 300, Staging bracket 300 includes a support platform 304, a wall engagement member 308, and a roof engagement member 312. Support platform 304 includes a support surface 316, outer rail 320, and inner rail 324. Support surface 316 is divided into one or more portions, e.g., 316A-B, so as to facilitate the placement of a plank during installation of a staging system, such as staging system 400A (FIG. 4). The size and dimensions of portion 316A should be such that it would support the plank while portion 316B is brought up for assembly with portion 316A.

Outer rail 320 is coupled to portion 316B and can include one or more brace holders 328 that can support brace members. As shown in FIG. 3, brace holders 328 are configured to provide for multiple, side-by-side, brace members for additional safety. Inner rail 324 is coupled to portion 316A and receives wall engagement member 308 via first receiver 330.

As with roof engagement members 112 and 224, roof engagement member 312 includes multiple tubular structures 168 that can be used to extend or retract the vertical (relative to ground-level) range of the roof engagement member. Roof engagement member 312 may also include a stabilizing bar 332 proximate a distal end of removable coupling 172. Stabilizing bar 332 provides support for staging bracket 300 and dampens swaying of the staging bracket when in use. Stabilizing bar 332 includes a coupling mechanism 336 that allows for attachment to the structure. As shown in FIG. 3, coupling mechanism 336 is an articulable coupling with a plurality of apertures for receiving fasteners. Alternative coupling mechanisms 336 may be employed depending up on the type of surface staging bracket 300 is being mounted on. Roof engagement member 312 is also sized and configured to accommodate the simultaneous positions of extension 340, which is discussed in more detail just below.

Staging bracket 300 can also include an extension 340. When roofing a structure, as workers come close to coupling mechanism 336 and/or coupling 172, they may skip an area where the coupling mechanism or coupling attaches to the roof and then return on a ladder to complete the roofing after the staging bracket has been removed. In order to avoid this inefficiency, extension 340 provides an alternative attachment point on the roof so that workers can apply roofing materials at the location where coupling 172 and/or coupling mechanism 336 were attached to the roof without having to remove staging bracket 300. As shown, extension 340 includes an articulable extension coupling 348 and a jack 352. The configuration of extension 340 is such that articulable extension coupling 348 attaches to the roof at a point below the roofline from coupling 172. In use, extension 340 is attached to inner rail 324 proximate first receiver 330 at attachment point 356 using pins or other connectors known in the art and then coupled to the roof using extension coupling 348. Jack 352 is then adjusted (e.g., extended) so as to relieve downward pressure on roof engagement member 312. In an exemplary embodiment, jack 352 is a screw jack, which, when operated, lowers or raises a jack support 360 using a rotator 364. Coupling 172 is then decoupled from the roof as a large portion of the downward pressure has been relieved by extension 340. Once coupling 172 is removed, workers can apply roofing materials to the former location of coupling 172 and/or coupling mechanism 336 and then reattach coupling 172 and/or coupling mechanism 336 to the roof (and possibly changing the type of coupling mechanism if necessary to accommodate the newly installed roofing material).

Turning now to FIG. 4, there is shown multiple exemplary staging brackets that are a part of multiple staging systems 400, e.g., staging systems 400A-B, attached to a structure 404. As mentioned previously, one of the many advantages of staging brackets according to the present disclosure are their adaptability, which is on display in FIG. 4. As shown, staging system 400A includes a pair of staging brackets 200 (FIG. 2), i.e., staging brackets 200 A-B, (although more could be used) that are each mounted to a roof 408 of structure 404. In this application, each staging bracket 200 includes a different coupling 172 because staging bracket 200A (closest to front of the page) needs to mount to a flat surface, such as plywood, and staging bracket 200B needs to mount to a standing seam roof. Coupling 172 for staging bracket 200B is similar in configuration to that described with FIG. 1, whereas coupling 172 for staging bracket 200B is similar in configuration to that shown in FIG. 5B.

Staging system 400B also includes a pair of staging brackets 200, i.e., staging brackets 200C-D, (although more could be used) that are mounted to a gable end 412 of structure 404, thus exemplifying one of the many benefits of the staging brackets as disclosed herein. Staging system 400B allows persons and/or materials to travel vertically along gable end 412 using additional tubular structures 168.

As discussed previously, each of the staging brackets discussed herein can include one or more brace holders, such as brace holder 132 (FIG. 1) for supporting braces. Examples of such implementations are shown in FIG. 4. For example, staging system 400A includes one brace member 416A, while staging system 400B includes a pair of parallel brace members 416B-C, Additional or alternative position of brace members is possible. Each staging system 400 also includes a plank 420 suitable for carrying workers and/or materials. Staging system 400A also includes two additional work shelves, a rear shelf 424 and a roof cleat 428 that mate with shelf brackets, such as shelf bracket 140, and cleat holders, such as cleat holder 184 (FIG. 1).

Turning now to exemplary embodiments of coupling 172, there is shown on FIG. 5A a coupling 500 suitable for use with a roof having corrugated roofing. Coupling 500 has a roof member 504 rotatably coupled to a connecting member 508. Roof member 504 sized and configured to be mountable on the corrugated roofing. In an exemplary embodiment, roof member 504 includes a channel 512 that has a height, H, and a width, W, sufficient to be positioned over a ridge in the corrugated. roofing material. On each side of channel 512 is a flange 516 that include a plurality of apertures for affixing roof member 504 to the roof. Apertures are including both in channel 512 and flanges 516 so as to accommodate different roofing styles (roofers have differing techniques for securing corrugated roofing to the roof of a structure).

In an exemplary embodiment, roof member 504 is coupled to connecting member 508 using a hinge 520. Hinge 520 facilitates the rotation of roof member 504 relative to connecting member 508, whereby when a staging bracket, such as staging bracket 100, is being deployed, coupling 500 can be mounted to the roof and the remainder of the staging bracket can be adjusted so as to provide a suitable working surface. In this way, coupling 500 serves to adapt any of the aforementioned staging brackets to roofs having different pitches.

Connecting member 508 is configured to mate with the remainder of roof engagement member 112. As shown, connecting member 508 is a designed to nest within a portion of roof engagement member 112 and the apertures in connecting member 508 are configures so as to mate with corresponding apertures in roof engagement member. Thus, coupling 500 can be joined to roof engagement member using pins or other mechanisms known in the art. Advantageously, coupling 500 (or other couplings discussed herein) can be mounted to the roof first and then the remainder of the staging bracket brought up and connected to the coupling, thereby easing assembly on the roof.

FIG. 5B shows another exemplary coupling, coupling 600. Coupling 600 is suitable for use with a roof having standing seam style metal roofing. Coupling 500 has a roof member 604 rotatably coupled to a connecting member 608. Roof member 604 is sized and configured to be mountable on the standing seam roofing, In an exemplary embodiment, roof member 604 includes an internal channel 612 that has a height, H, and a width, W, sufficient to be positioned over the flange protruding where adjacent pieces of the metal roofing material meet. Roof member 604 also includes an outer channel 614 sized and configured to substantially encase internal channel 612.

The width, W, of internal channel 612 is alterable so as to secure coupling 600 to the protruding flange. In an exemplary embodiment, channel 612 is expanded by a torsion spring or similar device located between internal channel 612 and outer channel 614. In an alternative embodiment channel 612 is formed by a hinge, such as a piano hinge, that is rotatable within outer chanenel 614. The width of channel 612 is reducible by using one or more clamps, set-screws (such as set-screws 618), or similar devices that press against one or more sidewalls of internal channel 612, compressing it against the flange protruding from the metal roof and keeping coupling 600 secured in place.

In an exemplary embodiment, roof member 604 is coupled to connecting member 608 using a hinge 620. Hinge 620 facilitates the rotation of roof member 604 relative to connecting member 608, whereby when a staging bracket, such as staging bracket 100, is being deployed, coupling 600 can be mounted to the roof and the remainder of the staging bracket can be adjusted so as to provide a suitable working surface. In this way, coupling 600 serves to adapt any of the aforementioned staging brackets to roofs having different pitches.

Connecting member 608 is configured to mate with the remainder of roof engagement member 112 (e.g., FIG. 1). As shown, connecting member 608 is a designed to nest within a portion of roof engagement member 112 and the apertures in connecting member 608 are configures so as to mate with corresponding apertures in roof engagement member. Thus, coupling 600 can be joined to roof engagement member using pins or other mechanisms known in the art. Advantageously, coupling 600 (or other couplings discussed herein) can be mounted to the roof first and then the remainder of the staging bracket brought up and connected to the coupling, thereby easing assembly on the roof.

FIG. 6 shows yet another embodiment of a staging bracket, staging bracket 700. Staging bracket 700 is similar to staging bracket 300 shown in FIG. 3, but with a few significant differences. For example, staging bracket 700 includes a truss support 704 that is releasably coupled to a support platform 708 (which is similar in design and structure to support platform 304) and does not include roof engagement member 312 (although it could be added as an additional roof support). Truss support 704 is sized and configured to hook overtop of a sidewall of the structure (best seen in FIG. 7), and when installed as a staging system (as seen in FIG. 7), it allows persons to work on structures that do not have a roof or only have rafters.

Staging bracket 700 also includes an end rail support 712 that couples to outer rail 716 (which is similar in design and structure to outer rail 320). To accommodate the addition of end rail support 712, outer rail 716 includes a pair of coupling members 720, e.g., 720A-B, that are sized and configured to receive ends of the end rail support. As shown in FIG. 7, end rail supports 712 sized and configured to prevent persons from falling off the sides of staging system.

When staging bracket 700 is combined with one or more staging brackets, such as staging brackets 700A and 700B, a staging system, as shown in FIG. 7, is created and is suitable for supporting persons and/or materials. As shown, the staging system allows person to work along the edge of a structure when roofing materials have not be affixed to the structure's rafters.

Turning now to FIG. 8, there is shown a method 800 of removing a staging bracket from a shingled roof. At step 804, a first portion of the staging bracket is removed by uncoupling it from the remainder of the staging bracket. In an exemplary embodiment, the first portion is an outer rail.

At step 808, a plank is removed, if applicable, from the support platform of the staging bracket.

At step 812, a second portion of the staging bracket is removed by uncoupling it from the portion of the staging bracket affixed to the roof. In an exemplary embodiment, the second portion is the inner rail and wall engagement member.

At step 816, a third portion of the staging bracket is removed by moving the portion in upward direction following the pitch of the roof. In an exemplary embodiment, the third portion is the roof engagement member.

Exemplary embodiments have been disclosed above and illustrated in the accompanying drawings. It will be understood by those skilled in the art that various changes, omissions and additions may be made to that which is specifically disclosed herein without departing from the spirit and scope of the present invention.
