Method and apparatus for suspending a package in an elevated position

Abstract

One embodiment provides a method and apparatus for suspending air conditioning duct works from a support structure comprising unistrut type support beams which apparatus includes a plurality of support brackets arranged and configured for being slidably interlockable with the interior of the unistrut beam members. The support brackets can be slid inside the interior of the support beam until adjacent a support beam which support beam can be connected to the support bracket. In like manner additional support brackets can be inserted into the interior of the support beam members to be adjustably located next to their respective support rod. In such manner multiple support rods can be used to support a frame member even where the support rods are not symmetrically located along the length of the support beam as the support bracket can be slid/moved inside the support beam until lining up with its respective support rod. Additionally, the entire support framework can be moved relative to the plurality of support rods by sliding the framework relative to the support brackets. In such manner the location of the supporting frame member can be changed without moving the support rods.

(24) FIG. 5 is a side view of support bracket 100 with an exploded view of a tensile member 800 (e.g., arm/rod/chain/cord/wire) for supporting in an elevated position bracket 300 hanging from a overhead support system such as a ceiling, beam, frame, etc.

(25) Support bracket 100 can be attached to tensile member 800 via opening 210 using threaded area 810, first nut 820 and second nut 830. Washers 822 and 832 can be used if desired.

(26) As shown in FIG. 5 second portion 380 of locking section 300 can have a height 390 between apex 310 and lower end 384 of second flange 380. First flange 340 and second flange 380 can make an angle 420. Angle 420 can be about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, and 90 degrees. In various embodiments angle 420 can be between about any two of the above referenced degree measurements.

(27) FIG. 6 shows side view of support bracket 100 along with a unistrut frame member 900 in which bracket 100 can be inserted in a locking fashion. In this disclosure a single frame member 900 100 will be described in detail. However, it is to be understood that the various framing members (e.g., 900′, etc.) can be constructed substantially similar to frame member 900, and do not need to be described separately.

(28) Framing member 900 can comprise top web 930 along with first flange 940 and second flange 950, and have first end 910 and second end 920. Top web 930 generally makes a 90 degree angle with first and second flanges 940,950. Between top web 930 and first and second flanges 940, 950 can be interior 970. Interior 970 can have a width 974 and height 972. At the bottom end of first flange 940 can be a socket 944 which generally faces interior 970, and in various embodiments faces top web 930. At the bottom end of second flange 950 can be socket 954 which generally faces interior 970, and in various embodiments top web 930. Between socket 942 and socket 954 can be an open gap 978.

(29) FIGS. 7, 8, and 9 illustrate the flexibility of positioning and frictionally locking support bracket 100 in framing member 900.

(30) FIG. 7 is a perspective view of support bracket 100 being inserted into framing member 900 through first end 910 (schematically indicated by arrow 904). FIG. 8 is a side view of support bracket 100 now inserted into framing member 900 and showing bracket 100 hanging in a locked but unsupported position in the interior 970 of frame. FIG. 9 is a side view of support bracket 100 now inserted into framing member 900 and with the bracket 100 being supported by support arm 800 and tending to apply to bracket 100 a rotational torque in the direction of arrow 1510 against framing member 900, with bracket 100 now supporting the framing member 900 and being in a longitudinally locked position (i.e., locked in the direction of longitudinal centerline 980). Such longitudinal locking occurs because of the frictional forces arising between bracket 100 and framing member 900 (where end 384 of bracket 100 is frictionally engaged with the interior side of socket 952 of framing member 900, and transition 250 of bracket 100 frictionally engages with the exterior side of socket 942 of framing member 900.

(31) As schematically indicated in FIG. 8, support bracket 100 is frictionally unlocked relative to framing member 900 when not attached to rod 800—where any frictional forces between support bracket 100 and framing member 900 are minimized, and allowing support bracket 100 to be rotated in the direction of arrow 1510 and slidably adjusted in a longitudinal direction while remaining within framing member 900. This slidable adjustability is schematically indicated by arrows 1610 in FIG. 7. It is noted that in this longitudinally-frictionally unlocked state, support bracket 100 is preferably still maintained in framing member 900 based on height 390 of second flange 390 being larger than the open distance 978 between socket 942 and socket 954, and preferably larger than the larger of: (a) width 974 less width 944 and (b) width 974 less width 954. In this manner bracket 100 will tend not to fall out of the interior 974 of framing member 900.

(32) FIG. 9 schematically shows bracket 100 entering a frictionally longitudinal locked (arrow 1500) and supported state relative to framing member 900. In this state lower end 384 of bracket 100 will enter the interior of socket 952, and bracket 100 will push against the exterior of socket 942. Tensile member 800 supports support bracket 100, and support bracket 100 supports framing member 900 as schematically indicated by arrow 1550.

(33) As schematically shown in FIG. 9, support bracket can be frictionally locked relative to framing member 900 be attaching rod 800 causing support bracket to be rotated direction of arrow 1500 entering a frictionally locked and supported state relative to framing member 900. In this state lower end 384 of bracket 100 will enter the interior of socket 952, and bracket 100 will push against the exterior of socket 942. Tensile member 800 supports support bracket 100 in the direction of arrow 1550, and support bracket 100 supports framing member 900 also in the direction of arrow 1550.

(34) Recessed area 255 can form a socket which reinforces the structural rigidity of framing member 900. As schematically indicted in FIG. 9 a load (indicated by arrow 1540) applied to framing member 900 will tend to cause flanges 940 and 950 to outwardly flex (schematically indicated by arrows 1542 and 1544). With such an event, in combination (a) recessed area 255 (e.g., acting as a socket) can cradle the end of flange 940 and (b) lower end 384 of second flange 380 held in socket 942 will resist such tendency of the flanges 940 and 950 to outwardly flex and thereby increase the amount of load framing member 900 can take before failure. In various embodiments, when compared to having not having flanges 940 and 940 reinforced against outwardly bending, such increase in load capacity can be greater than about 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 percent.

(35) As shown in FIG. 12 framing member 900 is part of an overall support structure 1000 for supporting a package 1200 in an elevated position, the structural configuration of support structure 2000 (e.g., plurality of interconnected support beams 2010) will resist framing member 900 from rotating in the direction of arrow 1500 when tensile member places a rotational load on bracket 100 which rotational load is transferred to support beam 900.

(36) In various embodiments the height of locking section (distance between lower end 384 and apex 310) can be greater than 50 percent of the height 972 of interior 970 of support beam 900. In various embodiments the height can be greater than 50, 55, 60, 65, 70, 75, 80, 85, 90, and 95 percent of the height 972 of interior 970 of support beam 900. In various embodiments the height can be between about any two of the above referenced percentages.

(37) In FIG. 9 is shown angle 260 can be formed between support flange 200 and first flange 940. Angle 260 can be about 45, 55, 65, 75, 85, 90, 95, 105, 115, 125, and 135 degrees. In various embodiments angle 260 can be between about any two of the above referenced degree measurements.

(38) FIG. 10 is an enlarged view of support bracket 100 where the portion of bracket 100 in the interior 970 of framing member 900 is shown in dashed lines. FIG. 11 is an enlarged view of support bracket 100 where a portion of framing member 900 has been cutaway.

(39) FIG. 12 is a perspective view of a support frame 2000 which supports, in an elevated position, a package 2200 (e.g., A/C ductwork). Support frame 2000 can comprise framing members 900 and 900′ along with a plurality of interconnected support beams 2010. Support frame 2000 can be supported in an elevated position by a plurality of tensile members 800, 800′, 800″, etc. which are respectively supporting a plurality of support brackets 100, 100′, 100″, etc. which are connected to a framing member 900 or 900′.

(40) Tensile members tensile members 800, 800′, 800″, etc. can themselves be supported themselves in a structure such as a ceiling, rafters, beams, etc. Tensile members 800 can be any structural element strong enough to support load or package 1200 at an elevated position in relation to a ground surface. Such members can be arms, rods, chains, cords, wires, etc.

(41) As schematically indicated in FIG. 12, in one embodiment the method comprises the following steps:

(42) (a) providing a support structure 2000 comprising first and second framing members 900,900′, each having first and second ends and interiors, which framing members 900, 900′ are structurally interconnected with each other;
