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 2.031 connects to a housing 2.040, which housing 2.040 is connected to a roof jack 2.017. The housing 2.040 comprises a first housing plate 2.039 and a second housing plate X.065, shown in FIG. 3 and other of the figures. The housing plates X.039/X.065 are generally parallel to one another. A first axle 2.047 spans from the first housing plate 2.039 to the second X.065. The first axle 2.047 may be secured to the housing 2.040 via, for example, a nut on threading and a washer. The first baluster 2.031 comprises a first baluster hole X.103 (in FIG. 8 at element 8.103). The first axle 2.047 may further comprise a sleeve, bushing, bearings, or similar between the first axle 2.047 and the baluster 2.031 as well as washers. The baluster may rotate around the first axle 2.047 when attached to the housing 2.040
The baluster 2.031 has a second baluster hole X.104 (visible in FIG. 8, at element 8.104); in FIG. 2, the second baluster hole is in the baluster 2.031 in the location of the second arc hole 2.043 and the pin of the first releasable pin 2.057. The second baluster hole X.104 intersects with the first and second housing plates along arc segments defined in large part by the location of the first axle 2.047, the location of the second baluster hole X.104, and the rotation of the baluster 2.031 around the first axle 2.047.
The housing 2.040 further comprises a first arc hole 2.041, a third arc hole 2.044, and a fourth arc hole 2.045. The arc segments and arc holes are discussed further in relation to FIG. 6. Corresponding arc holes in housing plate X.065 are shown in FIG. 8, though not numbered.
The baluster 2.031 may rotate around the first axle 2.047 and may be releasably secured in a particular orientation relative to the housing 2.040 by inserting the first releasable pin 2.057 through one of the arc holes; FIG. 2 shows the first releasable pin 2.057 as being inserted through arc hole 2.043.
The housing 2.040 further comprises a first housing attachment hole 2.059 in the first housing plate 2.039, through which a second releasable pin 2.061 may be passed; a corresponding housing attachment hole in the second housing plate X.065 is shown in FIG. 8 at element 8.058. Following removal of the second releasable pin 2.061, the length of the adjustable leg 2.025 (comprising first portion 2.026 and second portion X.109, both with adjustable leg holes X.028) may be adjusted such that adjustable leg holes X.028 in first portion 2.026 and second portion 2.109 align, the first housing attachment holes 2.059/8.058 may be aligned with the aligned adjustable leg holes X.028; the second releasable pin 2.061 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 2.040 further comprises a second housing attachment hole 2.053 in the first housing plate 2.039; a corresponding second housing attachment hole in housing plate X.065 is shown in FIG. 8 at element 8.106. A fastener, such as a bolt/nut combination, a releasable pin, and similar may be attached through the second housing attachment hole 2.053. 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 2.053 is depicted in figure two as being congruent with the roof jack top axle X.110 (in FIG. 9 at element 9.110), though the second housing attachment hole 2.053 may be congruent with an adjustable leg hole X.028, with a dedicated hole, or similar. When a fastener is passed through the second housing attachment hole 2.053, through the roof jack top axle X.110, and through the corresponding second housing attachment hole X.106, then the housing 2.040 is attached to the roof jack, though the housing 2.040 may rotate around the roof jack top axle X.110 and the length of the adjustable leg 2.025 may be adjusted; when a fastener, such as the second releasable pin 2.061, is inserted through the aligned adjustable leg holes X.028, as discussed above, then the housing 2.040 is attached to the roof jack 2.017 and the length of the adjustable leg is releasably set.
FIG. 2 also depicts first and second plate bolts at 2.049 and 2.051. These bolts attach the first housing plate 2.039 to the second housing plate X.065 through holes (see elements 8.100 and 8.102). One or more spacers, tube(s), washer(s) or similar may be located between the first and second housing plates 2.039/X.065 to hold the housing plates apart when one or more nuts are screwed onto the end(s) of the attachment holes/bolts at 2.049 and 2.051. An example of a spacer is shown in FIG. 12, feature 12.235. The housing plates may thereby be secured, one to the other, at a distance approximating the width of the adjustable leg 2.025.
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 2.024 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 2.033 and 2.037. Some or all of the rail brackets may be threaded; washer(s) 2.034 (a flat plate with two perforations where the rail brackets pass) and nuts, such as 2.035 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 3.029, the plank-receiving portion 3.024 of a first roof jack 3.017.A, first and second rails 3.036 and 3.038, and a second roof jack 3.017.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 4.071 comprises the first axle 4.047 as well as a second axle 4.073. In this embodiment, a releasable pin 4.056 has been inserted through openings in the housing 4.071, such as at the location labeled 4.073, and through the first baluster hole X.103, thereby attaching the baluster 4.031 to the alternative housing 4.071. As before, the baluster 4.031 may rotate around the second axle 4.073. The second axle 4.73 may comprise the releasable pin 4.056. In the depiction in FIG. 4, the releasable pin 4.057 is inserted through the first arc hole 4.041, securing the baluster 4.031 to the housing 4.071, 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 4.024 has an approximately horizontal aspect and the adjustable leg 4.025 has been lengthened (compared to the adjustable leg shown in FIG. 2 at 2.025), with the releasable pin 4.061 inserted through another set of aligned adjustable leg holes 4.028 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 5.071.

The first axle 6.047 has a relationship with the first arc hole 6.041, with equal-length line segments drawn between the first axle 6.047 and each of the first through fourth arc holes, 6.041, 6.043, 6.044, and 6.045. The arc holes are arranged along a first arc segment 6.081. As discussed above, the arc segment 6.081 is defined in large part by the location of the first axle 6.047, the location of the second baluster hole X.104 (not shown in FIG. 6, but occurring along arc segment 6.081), and rotation of the baluster X.031 around the axle. The location of the arc holes may be varied along the arc segment 6.081; the size and number of the arc holes may also be varied.
Housing plate 6.082 shows the first axle and arc holes shown in housing plate 6.080 as well as a second axle 6.089. Housing plate 6.082 is meant to be similar to housing plate X.071. The line segment drawn between the second axle 6.089 and arc hole 6.041 in housing plate 6.082 is meant to be the same length as the line segments between the first axle 6.047 and the arc holes along arc segment 6.081 in housing plate 6.080.
Housing plate 6.084 shows the features shown in housing plate 6.082 as well as a second arc segment 6.087 with a second set of arc holes along the second arc segment 6.087, obtained, approximately, by rotating a group around point 6.085, the group comprising: i) the set of arc holes along arc segment 6.081 and ii) the first axle 6.047.
Housing plate 6.086 shows the features shown in housing plate 6.084, less the arc hole which would otherwise be found within dotted circle 6.099. This arc hole may be omitted, for example, if the omitted arc hole is too close to another arc hole, such as arc hole 6.043. Instead of being omitted, one or more of the arc holes may be moved along the arc radii.
Housing plate 6.088 shows the features shown in housing plate 6.084, 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 6.091, 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 6.091, such that the arc holes in the two arc segments do not overlap. A close view of the arc segments from housing plates 6.084 and 6.088 is shown in FIG. 7.
Housing plate 6.090 shows the features in housing plate 6.080, 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 6.093 and 6.095 is greater than vertical and such that the line between 6.093 and 6.096 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 12.148, first 12.145, second 12.143, 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.
