     DETAILED DESCRIPTION 
       [0029]    The following detailed description refers to the accompanying drawings. 
         [0030]    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). 
         [0031]      FIG. 1  is a perspective view of a prior art roof jack, discussed above. 
         [0032]      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   
         [0033]    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 . 
         [0034]    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. 
         [0035]    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 . 
         [0036]    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. 
         [0037]    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. 
         [0038]      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 . 
         [0039]      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. 
         [0040]      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 ). 
         [0041]      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. 
         [0042]      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 . 
         [0043]    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. 
         [0044]      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 . 
         [0045]      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. 
         [0046]    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 . 
         [0047]    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 . 
         [0048]    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. 
         [0049]    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 . 
         [0050]    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. 
         [0051]      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. 
         [0052]      FIG. 7  is a close elevation view of embodiments of a housing plate. 
         [0053]      FIG. 8  presents perspective and perspective wire-frame views of a housing and a baluster, features of which are discussed elsewhere. 
         [0054]      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 .

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 ) 
         [0068]      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.” 
         [0069]      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&#39;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. 
         [0070]      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&#39;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. 
         [0071]      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. 
         [0072]      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 . 
         [0073]    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 . 
         [0074]    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. 
         [0075]    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.
