Adjustable Truss Pick

Abstract

The present invention relates to the field of hanging tubular space frame truss (truss) using truss picks. Truss units include tubular longitudinal truss chords, and tubular webbing elements interconnecting the truss chords. Truss picks attach to truss via the truss chords. Prior art truss picks were rigid and therefore incapable of adjusting attachment locations to account for variations in truss chord spacing. The invention described herein provides an adjustable truss pick having a swiveling saddle and clamp assembly that, as a result, creates adjustable spacing of truss pick attachment locations long desired in this field.

DETAILED DESCRIPTION OF THE INVENTION

[0026] Referring first to FIGS. 1-3, 4A, and 4B, in one aspect of the invention, the adjustable truss pick 200 of the present invention includes a body 100, an adjustable first saddle and clamp assembly 102, and may include a stationary second saddle and clamp assembly 104.

[0027] The adjustable first saddle and clamp assembly 102 includes a first saddle 106 that has a generally semi-circular inner surface profile, as substantially defined by the inner surface of first saddle 106. First saddle support 107 is located on the lower inside surface of first saddle 106. First clamp 108 is also generally semi-circular in profile, as substantially defined by its inner surface. First saddle 106 is connected to first clamp 108 by first clamp post 110 near the distal end 112 of first saddle 106 and the proximal end 114 of first clamp 108. First clamp post 110 is sized so as to permit first clamp 108 to swivel relative to first saddle 106, and, in the illustrated embodiment, extends through the distal end 112 of first saddle 106 as well as the proximal end 114 of first clamp 108, securing them in a swiveling relationship.

[0028] As seen more easily in FIGS. 3 and 4B, first swivel eye-bolt 116 is secured to the proximal end 118 of first saddle 106 through the eye of the first swivel eye-bolt 116 using first eye-bolt post 120. First eye-bolt post 120 extends through the proximal end 118 of first saddle 106 and the eye of the first eye-bolt post 120 in a manner so as to allow the first swivel eye-bolt 116 to swivel relative to first saddle 106. First swivel eye-bolt 116 preferably has a threaded stem surface.

[0029] Referring to FIG. 4B, formed in the distal end 122 of first clamp 108 is first forked slot 124 which is sized so as to receive the stem of first swivel eye-bolt 116 when the stem of first swivel eye-bolt 116 is swiveled toward the distal end 122 of first clamp 108.

[0030] First wing nut 126 has a winged head 128 and a hollow stem 130. Hollow stem 130 is threaded on the inner surface and sized so as to receive the threads of first swivel eye-bolt 116.

[0031] Adjacent first forked slot 124, and formed into the outer edge of first clamp 108, is first recessed nest 132, which is sized so as to receive the outer portion of hollow stem 130 of first wing nut 126.

[0032] As shown in FIGS. 4A, 4B, and 6, when first swivel eye-bolt 116 is rotated into position so that its stem is received within first forked slot 124, and the hollow stem 130 of first wing nut 126 receives the threads of first swivel eye-bolt 116, then first wing nut 126 may be tightened onto first swivel eye-bolt 116 until first wing nut 126 engages first recessed nest 132. As first wing nut 126 continues to be tightened, further engagement with first recessed nest 132 urges the distal end 122 of first clamp 108 toward the proximal end 118 of first saddle 106, tightening the interior generally circular perimeter substantially defined by the inner surfaces of first clamp 108 and first saddle 106, which swivel relative to each other around first clamp post 110.

[0033] Referring to FIGS. 1-3 and 4B, first relief 134 is formed in first clamp 108 proximate to first recessed nest 132 so as to permit the head 128 of first wing nut 126 to be twisted so as to tighten or loosen it without interference from first clamp 108.

[0034] First shoulder 136 of truss pick body 100 is located near one lateral end of the body 100. The adjustable first saddle and clamp assembly 102 is attached to the first shoulder 136 of body 100 using adjustable saddle post 138. The first saddle 106 may partially straddle truss pick body 100 including first shoulder 136. The adjustable saddle post 138 extends through the proximal end 118 of first saddle 106 and the first shoulder 136 of truss pick body 100, and is sized so as to permit the adjustable first saddle and clamp assembly 102 to swivel outwardly away from, and inwardly toward, the truss pick body 100.

[0035] Referring to FIGS. 1-3 and 4A, the stationary second saddle and clamp assembly 104 includes a second saddle 140 that is generally semicircular in profile, as defined by its inner surface. Second saddle 140 is connected to second clamp 142 by second clamp post 144 near the distal end 146 of second saddle 140 and the proximal end 148 of second clamp 142. In the illustrated embodiment, second saddle 140 is fixedly attached to, and preferably is integral with truss pick body 100. Second clamp 142 is also generally semi-circular in profile, as defined by its inner surface. Second clamp post 144 is sized in a manner to permit second clamp 142 to swivel relative to second saddle 140, and, in the illustrated embodiment, extends through the distal end 146 of second saddle 140 as well as the proximal end 148 of second clamp 142, securing them in a swiveling manner.

[0036] Second swivel eye-bolt 150 is attached to the proximal end 152 of second saddle 140 through the eye of the second swivel eye-bolt 150 using second eye-bolt post 154. Second eye-bolt post 154 extends through the proximal end 152 of second saddle 140 and the eye of the second swivel eye-bolt 150 so as to allow second swivel eye-bolt 150 to swivel relative to second saddle 140. Preferably, in the embodiment illustrated in FIGS. 1-3 and 4A, the proximal end 152 of second saddle 140 forms the second shoulder 155 of truss pick body 100 and is integral with it. Second swivel eye-bolt 150 includes a threaded surface on its stem. Second shoulder 155 is located laterally opposite first shoulder 136 on truss pick body 100.

[0037] The distal end 156 of second clamp 142 includes second forked slot 158 sized in a manner so it may receive the stem of second swivel eye-bolt 150 when the stem of second swivel eye-bolt 150 is swiveled toward the distal end 156 of second clamp 142.

[0038] Second wing nut 160 has a winged head 162 and a hollow stem 164. Hollow stem 164 has an interior that is threaded and sized to receive the threads on the stem of second swivel eye-bolt 150.

[0039] Proximate to second forked slot 158 and formed into the outer edge of second clamp 142 is second recessed nest 166. Second recessed nest 166 is sized so as to accommodate the outer portion of hollow stem 164 of second wing nut 160. When second wing nut 160 is rotated, the threads on the interior of hollow stem 164 engage the threads on the surface of the stem of second swivel eye-bolt 150, causing the second wing nut 160 to advance or retreat along the stem of second swivel eye-bolt 150.

[0040] When second swivel eye-bolt 150 is swiveled so that its stem is received within second forked slot 158, second wing nut 160 may be caused to engage second swivel eye-bolt 150, and may be twisted in a manner to advance the second wing nut 160 on the stem of second swivel eye-bolt 150 until it engages second recessed nest 166. Advancement (tightening) of second wing nut 160 further engages second recessed nest 166, urging the distal end 156 of second clamp 142 toward the proximal end 152 of second saddle 140, reducing the interior generally circular perimeter substantially defined by the inner surface of second clamp 142 and second saddle 140, as second clamp 142 is caused to rotate toward second saddle 140 around second clamp post 144.

[0041] Second relief 168 is provided in second clamp 142 near second recessed nest 166 to permit the winged head 162 of second wing nut 160 to be twisted without interference from second clamp 142.

[0042] Central suspension aperture 170 may be formed through the truss pick body 100 near the center between first shoulder 136 and second shoulder 155. Central suspension aperture 170 may be used to directly or indirectly attach a tension member (not illustrated and not part of the invention) for suspending the adjustable truss pick 200 from a fixture, such a as a permanent fixture, for example, a ceiling support structure.

[0043] First lateral suspension aperture 172 and second lateral suspension aperture 174 may likewise be formed through the body 100 on either side or both sides of central suspension aperture 170. The first and second lateral suspension apertures 172 and 174 are also provided for direct or indirect attachment of a tension member, and may be desirable if attachment to more than one tension member is desired, or if attachment to an off-center aperture is desired, for example, if an unbalanced load is being suspended. The availability of multiple suspension apertures 170, 172, and 174 provides the ability of an erector of rigging to utilize bridle rigging, providing multiple attachment points for tension members in order to stabilize a load supported by the rigging.

[0044] Bottom suspension aperture 176 may be provided for suspending a load directly or indirectly from the truss pick body 100, for example, by directly or indirectly attaching a tension member to the bottom suspension aperture 176 and suspending a load directly or indirectly from that tension member.

[0045] Weight relief 178 may be formed in the body 100 to promote balance or reduce weight in the adjustable truss pick 200.

[0046] Referring to FIGS. 5A-5C, a comparison, in particular, of FIG. 5B to FIG. 5C illustrates how swiveling the adjustable first saddle and clamp assembly 102 provides adjustability of the distance between the invention's attachment portions, namely, stationary second saddle and clamp assembly 104 (which may be attached to one truss chord of a unit of truss) and adjustable first saddle and clamp assembly 102 (which may be attached to a second parallel adjacent truss chord from the same unit of truss). When adjustable first saddle and clamp assembly 102 is swiveled toward the truss pick body 100, the distance between the locations attached to the two truss chords reaches an inner limit. Conversely, if adjustable first saddle and clamp assembly 102 is swiveled away from the truss pick body 100, the distance between the locations attached to the two truss chords reaches an outer limit. Comparing FIG. 5B to FIG. 5C, the difference between the inner limit and the outer limit illustrates the amount of adjustability achieved by the adjustable truss pick invention 200.

[0047] In operation, referring to the illustrations, the adjustable truss pick 200 works as follows.

[0048] The adjustable first saddle and clamp assembly 102 may be opened. This is done by twisting first wing nut 126 so it retreats (loosens) along the threaded stem of first swivel eye-bolt 116 and no longer resides in first recessed nest 132. First swivel eye-bolt 116 is then free to swivel upwardly out of first forked slot 124 so that first swivel eye-bolt 116 no longer engages first clamp 108. First clamp 108 then may be swiveled outwardly away from first saddle 106 so that the adjustable first saddle and clamp assembly 102 is open to accept a truss chord of a unit of truss.

[0049] Similarly, stationary second saddle and clamp assembly 104 may be placed in an open position. Second wing nut 160 may be twisted so that it retreats along the threaded stem of second swivel eye-bolt 150 until it no longer resides in second recessed nest 166. This permits second swivel eye-bolt 150 to swivel upwardly out of the second forked slot 158 so that second swivel eye-bolt 150 no longer engages second clamp 142. Second clamp 142 may then be swiveled outwardly away from second saddle 140. Stationary second saddle and clamp assembly 104 may then be opened to accept another truss chord from the same unit of truss as previously described.

[0050] A truss chord of a unit of truss may then be placed in the now open second stationary saddle and clamp assembly 104. The truss chord fits in the gap between the second saddle 140 and the second clamp 142. Second clamp 142 is then swiveled inwardly toward second saddle 140 until second clamp 142 abuts the truss chord. Second swivel eye-bolt 150 is swiveled downwardly until it engages second forked slot 158 of second clamp 142. Second wing nut 160 is twisted so that it advances (tightens) along the stem of second swivel eye-bolt 150, causing the stem 164 of second wing nut 160 to engaged second recessed nest 166, urging second clamp 142 to swivel toward second saddle 140, and causing second clamp 142 to tighten against the truss chord. When second wing nut 160 is sufficiently tightened, the truss chord is fully secured in the stationary second saddle and clamp assembly 104 between second clamp 142 and second saddle 140. The edges of second recessed nest 166 in this condition engage the stem 164 of second wing nut 160 which, because it is engaged with second swivel eye-bolt 150, prevents second swivel eye-bolt 150 from becoming disengaged from second forked slot 158, thus preventing the stationary second saddle and clamp assembly 104 from being disengaged from the truss chord, until such disengagement is desired. In that event, the second wing nut 160 may then be twisted to intentionally loosen it, and the stationary second saddle and clamp assembly 104 may be opened as previously described. The truss chord may then be removed.

[0051] With the first truss chord of a unit of truss already securely attached via the stationary second saddle and clamp assembly 104, another adjacent parallel truss chord from the same unit of truss may then be placed in the now-open adjustable first saddle and clamp assembly 102, fitting the truss chord in the gap between the first saddle 106 and the first clamp 108. Because this truss attachment location is not stationary, but rather is adjustable (see, in particular, FIGS. 5A, 5B, and 5C), first saddle 106 is swiveled relative to truss pick body 100 around adjustable saddle post 138 until first saddle 106 abuts the truss chord. This swiveling of the first saddle 106 corrects for width deviation issues as previously described that might arise vis-a-vis the two adjacent parallel truss chords from the same truss unit being attached to adjustable truss pick 200, and that might require adjustment to achieve a proper and secure fit between the adjustable truss pick 200 and both truss chords of the same unit of truss.

[0052] First clamp 108 is then swiveled inwardly toward first saddle 106 until first clamp 108 abuts the truss chord, which at this point should rest on first saddle support 107. First swivel eye-bolt 116 is swiveled downward to engage first forked slot 124 of first clamp 108. First wing nut 126 is twisted so that it advances and tightens on the stem of first swivel eye-bolt 116. This causes the stem 130 of first wing nut 126 to engage first recessed nest 132 of first clamp 108, which, in turn, urges first clamp 108 to swivel toward first saddle 106. This causes first clamp 108 to tighten, securing the truss chord between first clamp 108 and first saddle 106. As tightening of first wing nut 126 continues, the tightening of first clamp 108 against the truss chord urges the truss chord to move against first saddle 106, causing first saddle 106 to self-adjustto move to correct any remaining minor truss chord width issuesby swiveling about adjustable saddle post 138. A precise fit to the width between the two truss chords is thereby achieved, overcoming the problems discussed above relating to ordinary, rigid, prior art truss picks.

[0053] As first wing nut 126 is sufficiently tightened, the truss chord is fully secured in the adjustable first saddle and clamp assembly 102 between first saddle 106 and first clamp 108 in a heretofore difficult to achieve precise fit, a distinct benefit of this invention. The edges of first recessed nest 132 at this stage engage the stem 130 of first wing nut 126, preventing first swivel eye-bolt 116 from disengaging from first forked slot 124. This prevents the adjustable first saddle and clamp assembly 102 from becoming disengaged from the truss chord secured there, until such time as disengagement is desired. At that time, first wing nut 126 is loosened, first swivel eye-bolt 116 is swiveled upwardly, and the adjustable first saddle and clamp assembly 102 may be opened as previously described, allowing the truss chord to be removed.

[0054] Adjustable truss pick 200 may be suspended from a permanent fixture using one or more vertical tension members suspended from the permanent fixture, and attached directly or indirectly to truss pick body 100 using one or more of the suspension apertures in the body 100, namely the central suspension aperture 170, or the first or second lateral suspension apertures 172 and 174, in the manners previously described.

[0055] While the invention has been described with reference to specific embodiments and features, it will be appreciated by skilled practitioners that modifications and changes may be made without departing from the scope of the invention. It is to be recognized that optimal dimensional relationships for the components of the present invention may include variations in size, materials, shape, form, and manner of operation. In particular, while the illustrated embodiment discussed an embodiment of the invention having one adjustable saddle and clamp assembly 102 attached to the body so that it may swivel, and one stationary saddle and clamp assembly 104 attached to the body so that it does not swivel, skilled practitioners will recognize that the stationary saddle and clamp assembly 104 may be replaced by a second adjustable saddle and clamp assembly similar to the first 102, that also swivels, without departing from the scope of the invention.
