DETAILED DESCRIPTION The following detailed description refers to the accompanying drawings.
The following detailed description is for the purpose of illustrating embodiments of the invention only, and other embodiments are possible without deviating from the spirit and scope of the invention, which is limited only by the appended claims. The figures and elements discussed in this specification use terms meant as examples and not as limitations. Functions equivalent to those illustrated in the figures may be provided by other device(s) or structure(s).
FIG. 1 is a perspective view of a prior art roof jack, discussed above.
FIG. 2 is an elevation view of a roof jack and an attached safety rail baluster. In this view, a first baluster 031 connects to a housing 040, which housing 040 is connected to a roof jack 017. The housing 040 comprises a first housing plate 039 and a second housing plate 065, shown in FIG. 3 and other of the figures. The housing plates 039/065 are generally parallel to one another. A first axle 047 spans from the first housing plate 039 to the second 065. The first axle 047 may be secured to the housing 040 via, for example, a nut on threading and a washer. The first baluster 031 comprises a first baluster hole X.103 (in FIG. 8 at element 103). The first axle 047 may further comprise a sleeve, bushing, bearings, or similar between the first axle 047 and the baluster 031 as well as washers. The baluster may rotate around the first axle 047 when attached to the housing 040
The baluster 031 has a second baluster hole 104 (visible in FIG. 8, at element 104); in FIG. 2, the second baluster hole is in the baluster 031 in the location of the second arc hole 043 and the pin of the first releasable pin 057. The second baluster hole 104 intersects with the first and second housing plates along arc segments defined in large part by the location of the first axle 047, the location of the second baluster hole 104, and the rotation of the baluster 031 around the first axle 047.
The housing 040 further comprises a first arc hole 041, a third arc hole 044, and a fourth arc hole 045. The arc segments and arc holes are discussed further in relation to FIG. 6. Corresponding arc holes in housing plate 065 are shown in FIG. 8, though not numbered.
The baluster 031 may rotate around the first axle 047 and may be releasably secured in a particular orientation relative to the housing 040 by inserting the first releasable pin 057 through one of the arc holes; FIG. 2 shows the first releasable pin 057 as being inserted through arc hole 043.
The housing 040 further comprises a first housing attachment hole 059 in the first housing plate 039, through which a second releasable pin 061 may be passed; a corresponding housing attachment hole in the second housing plate 065 is shown in FIG. 8 at element 058. Following removal of the second releasable pin 061, the length of the adjustable leg 025 (comprising first portion 026 and second portion 109, both with adjustable leg holes 028) may be adjusted such that adjustable leg holes 028 in first portion 026 and second portion 109 align, the first housing attachment holes 059/058 may be aligned with the aligned adjustable leg holes 028; the second releasable pin 061 may then be inserted through the aligned holes to secure the adjusted length of the adjustable leg and the housing on the roof jack.
The housing 040 further comprises a second housing attachment hole 053 in the first housing plate 039; a corresponding second housing attachment hole in housing plate 065 is shown in FIG. 8 at element 106. A fastener, such as a bolt/nut combination, a releasable pin, and similar may be attached through the second housing attachment hole 053. All uses of the term “fastener” herein shall be understood to refer to any of a bolt/nut combination, a releasable pin, and similar. The second housing attachment hole 053 is depicted in figure two as being congruent with the roof jack top axle 110 (in FIG. 9 at element 110), though the second housing attachment hole 053 may be congruent with an adjustable leg hole 028, with a dedicated hole, or similar. When a fastener is passed through the second housing attachment hole 053, through the roof jack top axle 110, and through the corresponding second housing attachment hole 106, then the housing 040 is attached to the roof jack, though the housing 040 may rotate around the roof jack top axle 110 and the length of the adjustable leg 025 may be adjusted; when a fastener, such as the second releasable pin 061, is inserted through the aligned adjustable leg holes 028, as discussed above, then the housing 040 is attached to the roof jack 017 and the length of the adjustable leg is releasably set.
FIG. 2 also depicts first and second plate bolts at 049 and 051. These bolts attach the first housing plate 039 to the second housing plate 065 through holes (see elements 100 and 102 in FIG. 8). One or more spacers, tube(s), washer(s) or similar may be located between the first and second housing plates 039/065 to hold the housing plates apart when one or more nuts are screwed onto the end(s) of the attachment holes/bolts at 049 and 051. An example of a spacer is shown in FIG. 12, feature 235. The housing plates may thereby be secured, one to the other, at a distance approximating the width of the adjustable leg 025.
FIG. 2 also depicts that the bottom of the roof jack is approximately 70 degrees up from a vertical line, 20 degrees down from a horizontal line. The plank-receiving portion 024 is not depicted as horizontal. These angles are shown as examples only; see FIG. 4 for an example of a roof jack and baluster set to accommodate a roof with a pitch angle of 45 degrees. By providing a roof jack and a baluster attachment which are adjustable, the roof jack and baluster may be used on a wide range of roof angles, accommodate a range of use cases and preferences, including standing materials on the plank receiving portion and giving the plank receiving portion a non-horizontal.
FIG. 2 also depicts first and second rail brackets 033 and 037. Some or all of the rail brackets may be threaded; washer(s) 034 (a flat plate with two perforations where the rail brackets pass) and nuts, such as 035 or similar, may be screwed onto the threaded portion to thereby hold a rail on the baluster (see FIG. 3).
FIG. 3 is a perspective view of a set of roof jacks, attached safety rail balusters, safety rails, and a plank. FIG. 3 depicts a plank 029, the plank-receiving portion 024 of a first roof jack 017.A, first and second rails 036 and 038, and a second roof jack 017.B.
FIG. 4 is an elevation view of a roof jack and an attached safety rail baluster, showing alternative embodiments. In this depiction, an alternative housing 071 comprises the first axle 047 as well as a second axle 073. In this embodiment, a releasable pin 056 has been inserted through openings in the housing 071, such as at the location labeled 073, and through the first baluster hole 103, thereby attaching the baluster 031 to the alternative housing 071. As before, the baluster 031 may rotate around the second axle 073. The second axle 73 may comprise the releasable pin 056. In the depiction in FIG. 4, the releasable pin 057 is inserted through the first arc hole 041, securing the baluster 031 to the housing 071, with an approximately vertical aspect. FIG. 4 is an example of an alternative configuration. Additional alternative configurations of axle(s) and arc holes are shown in and discussed in relation to FIG. 6.
In FIG. 4, the bottom of the roof jack is depicted as approximately 45 degrees up from a vertical line. The plank-receiving portion 024 has an approximately horizontal aspect and the adjustable leg 025 has been lengthened (compared to the adjustable leg shown in FIG. 2 at 025), with the releasable pin 061 inserted through another set of aligned adjustable leg holes 028 to achieve this configuration.
FIG. 5 is a perspective view of a set of roof jacks, attached safety rail balusters, safety rails, and a plank, showing the example alternative housing 071.
FIG. 6 is an elevation view of embodiments of a housing plate. In housing plates 080, 082, 084, 086, and 088 there is a first axle 047. The first axle 047 has a relationship with the first arc hole 041, with equal-length line segments drawn between the first axle 047 and each of the first through fourth arc holes, 041, 043, 044, and 045. The arc holes are arranged along a first arc segment 081. As discussed above, the arc segment 081 is defined in large part by the location of the first axle 047, the location of the second baluster hole 104 (not shown in FIG. 6, but occurring along arc segment 081), and rotation of the baluster 031 around the axle. The location of the arc holes may be varied along the arc segment 081; the size and number of the arc holes may also be varied.
Housing plate 082 shows the first axle and arc holes shown in housing plate 080 as well as a second axle 089. Housing plate 082 is meant to be similar to housing plate 071. The line segment drawn between the second axle 089 and arc hole 041 in housing plate 082 is meant to be the same length as the line segments between the first axle 047 and the arc holes along arc segment 081 in housing plate 080.
Housing plate 084 shows the features shown in housing plate 082 as well as a second arc segment 087 with a second set of arc holes along the second arc segment 087, obtained, approximately, by rotating a group around point 085, the group comprising: i) the set of arc holes along arc segment 081 and ii) the first axle 047.
Housing plate 086 shows the features shown in housing plate 084, less the arc hole which would otherwise be found within dotted circle 099. This arc hole may be omitted, for example, if the omitted arc hole is too close to another arc hole, such as arc hole 043. Instead of being omitted, one or more of the arc holes may be moved along the arc radii.
Housing plate 088 shows the features shown in housing plate 084, except that the set of arc holes radiating from the second axle and the second axle have been shifted down, such that the arc segments overlap at location 091, and except that the set of arc holes radiating from the second axle and the second axle have also been rotated counter-clockwise slightly around location 091, such that the arc holes in the two arc segments do not overlap. A close view of the arc segments from housing plates 084 and 088 is shown in FIG. 7.
Housing plate 090 shows the features in housing plate 080, except that the group comprising the set of arc holes radiating from the first axle and the first axle have been rotated counter-clockwise such that the line segment between locations 093 and 095 is greater than vertical and such that the line between 093 and 096 is approximately vertical.
FIG. 6 is meant to show that more than one axle is possible and that other arrangements of axles and arc holes are possible. Additional arrangements are possible, such as the example shown in FIG. 12, including one baluster axle 148, first 145, second 143, and third baluster holes, and, on a housing, staggered arc holes on two arc segments, a first arc segment being defined by the distance between the one baluster axle and the second baluster hole, the second arc segment being defined by the distance between the one baluster axle and the third baluster hole.
FIG. 7 is a close elevation view of embodiments of a housing plate.
FIG. 8 presents perspective and perspective wire-frame views of a housing and a baluster, features of which are discussed elsewhere.
FIG. 9 presents an elevation view of a roof jack and a safety rail housing, showing where and how the housing attaches to the roof jack. The second housing attachment hole 053 engages with the roof jack top axle 110 while the releasable pin 061 at the first housing attachment hole 059 engages with hole 107 in the adjustable leg second portion 109, releasably securing the length of the adjustable leg 025.
FIG. 10 presents an elevation view of a safety rail baluster 111 attached to a safety rail base 115 attached to a quick connect roof clip 004. In this view, the safety rail base 115 is bolted to a semi-circular housing 113. The semi-circular housing 113 comprises two semi- circular plates 124 and 126. The two semi-circular plates 124 and 126 are held together by connectors 117, 119, and axle 121 at a first baluster hole, illustrated by element 129 in FIG. 11. The connectors may comprise sheaths, tubes, washers, or other separators or spacers to hold the two semi-circular plates 124 and 126 a fixed distance apart. The baluster 111 includes a second baluster hole, illustrated by element 131 in FIG. 11. The second baluster hole describes an arc segment along the two semi-circular plates 124 and 126. Arc holes along the arc segment, such as arc hole 123, form openings from one side of the housing 113 to the other. The releasable pin 125 may be inserted into one of the openings and through the second baluster hole 131 to releasably secure the baluster 111.
In the view presented in FIG. 10, the safety rail base 115 is connected to the quick connect roof clip 004 by an attachment head 016. The attachment head .016 is connected to the safety rail base 115 by, for example, two bolts, such as 019. The attachment head 016 comprises a projection 018, which releasably connects the attachment head 016 and the attached safety rail base 115 to the quick connect roof clip 004
FIG. 11 presents perspective and perspective wireframe views of a safety rail baluster attached to a quick connect roof clip.
FIG. 12 presents an elevation view of a detail of a housing plate and baluster embodiment.
FIG. 13 is a perspective view of a quick connect roof clip 004. The quick connect roof clip 004 comprises a first portion 005 with at least one hole or perforation 006, a connecting portion 007, and a second portion 008.
The second portion 008 comprises an opening 009. In an alternative embodiment, the second portion 008 may comprise a projection suitable for releasable attachment to a corresponding opening. In an alternative embodiment, the second portion 008 may comprise both a projection and an opening, each of which are suitable for releasable attachment to a corresponding opening/projection. In an alternative embodiment, the second portion 008 may be a projection received by a corresponding opening. All such cases may be referred to in the claims as “a connector” and shall be understood to be equivalent to “a connector.”
In the clip shown in FIG. 13, the perforations 006 are sized approximately to accommodate 16d framing nails and the connection portion 007 is at a 45° angle to both the first 005 and second portions 008. As used throughout the specification and claims, a clip (or any term including “clip”) shall be understood not to include a nail or screw. The angle of the connection portion 007, as shown, is suited to shedding debris when/if the connection portion 007 is left attached to the roof. In an alternative embodiment, the connecting portion 007 may be at a 90° angle or another angle. In an alternative embodiment, the connecting portion 007 may be omitted. As shown, the second portion 008 is parallel to the first portion 005. In an alternative embodiment, the second portion 008 may have a different angle relative to the first portion 005. In an alternative embodiment, the connecting portion 007 may be omitted and the second portion 008 may have a 45° angle relative to the first portion 005.
As shown in FIG. 13, the opening 009 comprises a wider portion 010 and a narrower portion 011 which together form a gravity-locking clip when engaged with a corresponding projection. In other embodiments (not shown), the opening 009 may form any of a range of shapes to accommodate corresponding projections. In other embodiments (not shown), the opening 009 may form a clip other than a gravity-locking clip, such as a clip with a non-gravity dependent mechanical locking mechanism. All such cases may be referred to in the claims as “a connector” and shall be understood to be equivalent to “a connector.”
As shown in FIG. 13, the opening 009 is sized to accommodate both a corresponding projection from a roof jack (see FIGS. 17 and 18) and a lanyard attachment (see FIG. 19).
FIG. 14 is a perspective view of a quick connect roof clip comprising a second opening 012. As shown, the second opening 012 may act as an alternative attachment point for a lanyard attachment or another device or attachment.
FIG. 15 is a perspective view of a quick connect roof clip 004, showing features of a roof, including a shingle 013, lines 014 where a rafter may lay beneath the quick connect roof clip (to which the quick connect roof clip may be nailed), and a line 015 showing where the shingle lays when down on the roof, as shown in FIG. 16. As used herein, a rafter shall be considered part of a roof.
FIG. 17 is a perspective view from above of a quick connect roof clip 004, a quick connect attachment head 016, and a quick connect roof jack 017. The quick connect attachment head 016 is shown as being a separate component from the quick connect roof jack 017; in an alternative embodiment, the functions provided by the quick connect attachment head 016 may be provided by an element on or of the quick connect roof jack 017, such as if the quick connect roof jack 017 were to comprise a projection corresponding to the opening 009. As shown, the quick connect attachment head 016 comprises a projection 018 corresponding to the opening 009.
As shown, the quick connect attachment head 016 further comprises at least one connector 019, connecting the quick connect attachment head 016 to the quick connect roof jack 017. The connectors 019 may be threaded and comprise nuts 020. In alternative embodiments, a range of connectors (with or without threads, nuts, cotter pins, other fasteners) may be utilized. Not shown, a washer or other spacer may be interposed between the bottom of the quick connect attachment head 016 and the quick connect roof jack 017. The washer or other spacer may be a tube, square, rectangle, etc., and may be connected or affixed to the quick connect roof jack 017 and/or the quick connect attachment head 016. As shown, the quick connect attachment head 016 further comprises an optional eye 021 suitable for a lanyard attachment (see FIG. 19)
FIG. 18 is a perspective view from below of a quick connect roof clip 004, a quick connect attachment head 016, and a quick connect roof jack 017. This perspective view shows the projection 018 engaged with the opening 009. This perspective shows that the projection 018 comprises a wider portion 022, sized to fit through the wider portion of the opening 010 but not through the narrower portion of the opening 011. Thus, when gravity pulls down and back (away from the quick connect attachment head 016) on the quick connect roof jack 017, the projection 018 and opening 009 together form a gravity-locking connector which prevents the quick connect roof jack 017 from disengaging from the quick connect roof clip 004, unless a force, such as may be provided by a person, counter-acts the gravitational force. All such cases may be referred to in the claims as “a connector” and shall be understood to be equivalent to “a connector.”
FIG. 19 is a perspective view of a quick connect roof clip 004, a lanyard attachment 023, a quick connect attachment head 016, and a quick connect roof jack 017. This perspective shows that the opening 009 may be large enough to simultaneously accommodate the projection 018 and the lanyard attachment 023. Not shown, the opening 009 may be large enough to simultaneously accommodate the projection 018, the lanyard attachment 023, and to allow the quick connect roof jack 017 and projection 018 to be lifted up and disengaged from the opening 009 without removal of the lanyard attachment 023. Alternatively, and as discussed in relation to FIG. 14, a second opening, such as 012, may be provided for attachment of the lanyard attachment 023. Alternatively, and as discussed in relation to FIG. 17, an optional eye 021 may be provided for attachment of the lanyard attachment 023. As shown, the optional eye 021 is part of or affixed to a connector 019; in alternative embodiments, the eye 021 may have a dedicated attachment to the quick connect attachment head 016 and/or the quick connect roof jack 017; in an alternative embodiment the quick connect attachment head 016 may have an opening for attachment of the lanyard attachment 023. In alternative embodiments, the quick connect roof jack 017 may include a different and/or additional opening or securement point for attachment of a lanyard attachment 023. The lanyard attachment 023 is shown for simplicities sake without the rope, webbing, cable, cord or similar which may attach the lanyard attachment 023 to a worker's safety harness, to another rope, webbing, cable, cord or similar. The lanyard attachment 023 may be another shape or structure than as shown, such as a locking or non-locking carabiner, rope, cord, webbing, cable or similar passed through the opening 009 and releasably secured. Lanyard attachments 023 are understood herein to be releasably attachable.
FIG. 20 is a perspective view from above of a quick connect roof jack 017, a quick connect attachment head 016, a quick connect roof clip 004, and a lanyard attachment 023. The quick connect roof jack 017 is depicted as comprising a plank-receiving portion 024 which may be adjusted to have a generally horizontal angular relationship with the ground or other frame of reference; the plank-receiving portion's 024 angular relationship may be adjusted by changing the length of the adjustable-length portion 025. The length of the adjustable-length portion 025 may be changed by, for example, disengaging retaining clip 026 from one side of the pin 027, which may allow the pin 027 to be withdrawn from the aligned holes 028, the relative overlap of the components of the adjustable-length portion 025 to then be adjusted, and the pin 027 to be inserted into a new set of aligned holes 028. Another mechanism may be used to adjust the angular relationship of plank-receiving portion 024 to the ground or other frame of reference, such as an adjustable-length portion 025 with an outer and an inner portion and a clamp (such as a screw clamp) to clamp the two in a releasable relationship.
FIG. 21 is a perspective view from above of a set of quick connect roof jacks 017 spanned by a plank 029. Not shown, a screw, bolt, bracket or similar may be utilized to secure the plank 029 to one or more of the quick connect roof jacks 017. The plank may be wood, metal, composites, a manufactured structure or a mixture thereof.
FIG. 22 is a perspective view from the side of a set of quick connect roof jacks 017 spanned by a plank 029. FIG. 22 is meant to depict the plank 029 as having a generally horizontal angular relationship with the ground. As in other of the figures, a shingle is not shown covering much of the first portion of the quick connect roof clip 004.
As shown in the figures and as discussed above, a quick connect roof clip 004 is releasably attachable to at least one quick connect roof jack 017. As noted, the quick connect roof clip 004 is releasable from the quick connect roof jack 017 and may be left in place for later use. A structure or element is provided for attachment of a lanyard attachment 023. The quick connect roof clip 004 and quick connect roof jack 017 may be releasably connected by a quick connect attachment head 016, though the projection or opening on the attachment head 016 corresponding to the opening or projection on the quick connect roof clip 004 may be part of or provided by a structure or element on or of the quick connect roof jack 017.
As used herein, “releasably attachable” and “releasably connectable” are understood to be equivalent; “attach” and “connect” (and “attachable” and “connectable”) are also understood to be equivalent; and “releasable,” “releasably,” “releasably attachable,” and/or “releasably connectable” are understood to mean being able to be repeatedly connected/disconnected (or engaged/disengaged) through the use of the hands, feet, or human appendage, with application of human-scale work effort, not generally requiring the use of a tool.
The components discussed in this specification may be made of or from a wide range of materials non-exclusively including aluminum, steel, iron, copper, tin and alloys between and including these and other materials, as well as and/or including composites such as fiber-glass, aramid, carbon-fiber, an other fibers combined with resin and/or epoxy, and wood.
