A truss assembly utilizing three basic components which separately include support rods, triangular brace members and clamp members for coupling the corners of the triangular brace members to the respective support rods. The triangular brace members include three linear connecting supports joined at their adjacent ends to form a triangle and wherein each corner joint terminates in a semicircular flange having a central semicircular surface with a central access opening running parallel with respect to the axis of the other semicircular flanges. An angular relationship is established between the linear connecting supports or brace members so that when the flanges are engaged with the support rods, a third semicircular flange couples with another tubular support wherein the support components of the brace members are angled with respect to the connecting supports.
Description
TRUSS ASSEMBLY
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to the field of truss constructions useful in building platforms, scaffolding or the like, and more particularly to a novel assemblage of preformed triangular and stackable brace sections which are used in com-bination with support rods and clamps to provide a rigid and load-bearing structure.
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to the field of truss constructions useful in building platforms, scaffolding or the like, and more particularly to a novel assemblage of preformed triangular and stackable brace sections which are used in com-bination with support rods and clamps to provide a rigid and load-bearing structure.
2. Brief Description of the Prior Art In the past, it has been the conventional practice to construct platforms, scaffolding or the like by using a plurality of elongated beams which are connected together by a variety of bolts, brackets, gusset plates or the like into a unitary construction. In some instances, a platform is constructed by using a box beam construction by utilizing tubular members which are arranged in parallel and are joined together by suitable brackets so as to provide a square con-figuration in cross-section. A plurality of such box beam constructions are then loaded on a truck to the using site.
Difficulties and problems have been encountered when employing typical box beam constructions in that load-ing a multiplicity of such constructions onto the flat bed of a truck requires a great deal of space of which a sub-stantial area is unused since the interior of the box beam construction is empty and void of any structural members.
Also, it is a difficult arid labor intensive effort to load and unload the preformed box beam constructions and such an effort generally requires mechanical equipment, such as hoists, lifts or the like. Furthermore, it is not prac-tical to erect or construct the box beam constructions at a using site because of the great r_umber of compener_t parts used to build the beam construction. Aside from the corner rods or beams, there are many braces, clamps, brackets and stringers which must be assembled in order to produce the complete bcx beam construction. Consequently, it is the usual practice to construct or built each bcx beam construc-tion at a warehouse site and then transport the separate arid individual box beam constructions to the using site where they are then unloaded and connected together to provide the intended platform, scaffolding or the like.
Therefore, there has been a long-~tarding need to provide a novel construction or assemblage for platforms and scaffolding whicl-~ may be readily assembled at the using site from no more than three components that are readily transportable in a stackable or nested relationship to avoid transportation problems. Preferably, the components for the truss assemblage should have no more than three basic components and the components should be readily stackable and packable into convenient packar,.es for removal from a transportation vehicle to tre using site where assem-blage of the components can take place.

SUN:MARY OF THE INVENTION
Accordingly, the above problems and difficulties are avoided by the present invention which provides a novel truss assemblage which is put together utilizing three basic components which separately include support rods or members, triangular brace members and clamp members for coupling the corners of the triangular components or braces to the respect support rods or members. The tri-angular brace members include three supports joined at their adjacent ends to form a triangle and wherein each joined corner terminates in a semicircular flange wherein each flange has a central semicircular opening with a central access running parallel with respect to the axes of the other semicircular flanges. An angular relation-ship is established between the flanges and the connecting supports so that when a pair of flanges is coupled to a pair of support rods, the third semicircular flange couples with another tubular support wherein the support components of the brace are angled with respect to the support members.
A feature of the invention resides in employing a clamp for releasably joining with each of the respective semicircular flanges to hold the truss or brace members to the respective tubular supports and wherein each of the respective clamps includes a movable shoe having a threaded member for advancing the shoe into releasable interference connection with the exterior of a support rod or tube on which the brace members are attached. A further innovation resides in making the brace members of equal length and shape so as to be stackable or nestable during transport from one place to another.
Therefore, it is among the primary objects of the present invention to provide a novel truss assemblage having a triangular cross-section wherein the assemblage is composed of three major components including support rods connected together by triangular brace members and having clamp means.
Another object of the present invention is to provide a novel load-bearing truss assembly having a plurality of rods which are joined together by a triangular truss or brace component such that the overall cross-section of the structure is triangular and wherein the truss or brace com-ponents are stackable for shipping and storage purposes.

_g_ DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGURE 1, the novel truss assembly is illustrated in the general direction of arrow 10 wherein the assembly comprises a first truss section, indicated in the direction of arrow 11, and a second truss assemblage arranged at right angles or perpendicular to the assemblage 11 and the second assemblage is illustrated in the direction of arrow 12. Truss assemblage 11 includes tubular support members 13 and 14 with a third support member 15, as illus-trated in FIGURE 2. The support members are maintained in fixed parallel spaced-apart relationship and in cross-sec-tion, provide an assemblage which is triangular. The triangular cross-section is more clearly illustrated with respect to the truss assemblage 12 where it can be seen that at least three support members, identified by numerals 16, 17 and 18, are held i.n fixed spaced-apart relationship by means of a triangular brace 20. Triangular braces 21 and 22 maintain the support members of the truss assemblage 11 in fixed spaced-apart.relationship. Each brace is of triangular configuration and plan view and comprises ribs or element s 23, 24 and 25 as typically illustrated with respect to the truss assembly 12. The truss elements or ribs 21 and 22 are similarly inclusive of the ribs and elements. It is to be particularly noted that coupling members are carried at each corner of the triangular _g_ arrangement of ribs or elements comprising each of their respective braces. For example, coupling members 30 and 31 are employed to join the corners of bracket or brace 21 to the support members 13 and 14 respectively. As shown in FIGURE 2, a coupling member of identical construction is identified by numeral 32 and couples the third corner of the brace 21 to the support member 15. It is to be par-ticularly noted that each of the respective codpling members, such as members 30 and 31, lie along parallel axes, such as axis 33;and axis 34. However, the inter-connecting elements or ribs are in angular relationship with respect to these axes and are not normal or perpen-dicular with respect to the axis 33 or 34.
It can be seen in FIGURES 1 and 2 that the truss assembly 11 is attached to the truss assembly 12 by means of T-connectors 35 and 36 which interconnect the midsection of support tube 16 with the extreme ends of the tubes 14 and 15. Also, the tube 13 is connected to the support tube 17 by means of a T-shaped connector 37.
Referring now in detail to FIGURE 3, it can be seen that the brace 21 is connected to the respective support tubes 13, 14 and 15 by means of coupling devices 30, 31 and 32. Each coupling device includes grooves on. opposite sides, such as groove 37 carried in coupling 31. The grooves are connected together by means of an arcuate midsection 38 and the grooves are intended to receive outwardly extending flanges 40 and 41 of the triangular shaped brace 21. The flanges 40 and 41 are disposed on opposite ends of a curved or arcuate portion 42 so that when the coupling 31 is slid along the outside of tube 14, the flanges 40 and 41 will enter the grooves or slot s 37 and portion 42 will be on the inside of the tubular structure. A feature resides in the fact that the ends of the grooves, such as indicated by numeral 43, serve as a stop to prevent the coupling from passing completely over the flanges 40 and 41. When the coupling and the flanges including the mid portion 42 are connected together, a complete circle is provided about the struc-tural tube 14. In a similar fashion, it can be seen in FIGURE 3 that the coupling 32 has been connected with the flanges so as to clamp the corner of the triangular brace to the tube 15. The semicircular center portion is indicated by numeral 44. In a similar fashion, coup-ling 30 is carried on the exterior and outer side of the tubular member 13 and is slid over flanges carried on the corner of the triangular brace 21 in a manner as previously described. The flanges enter the groove and are stopped by the stops at the end of the groove so that the coupling 30 is in a position to be releasably secured.
Referring to FIGURE 4, releasable securement is illus-trated by means of a threaded nut 45 which may be screwed through a portion 46 wherein a shoe 47 is moved against the exterior surface of the tube 15. When it is desired to remove the brace, the screw is reversed and the shoe is loosened so that the coupling can be disconnected to free the brace from the supporting rods or tubes.
Referring to FIGURE 5, it can be seen that the tri-angular braces may be stored in a stacked or nestable relationship one on top of another during transport or shipping. Additionally, the support tubes 13, 14 and 15 can also be carried in a bundle adjacent to the stacked triangular braces and the coupling elements can also be carried in a box. The entire multiplicity of components is, carried in a disassembled association or arrangement on a truck bed and immediate and rapid assembly of the truss structure or scaffolding can take place at the site of use. Therefore, a substantial space-saving feature is achieved by utilization of the present inven-tion wherein box structures require substantially more room during transport and involve a great deal of wasted space. The stack of triangular braces is indicated in the direction of arrow 48 with numeral 49 indicating the lowermost brace in the stack while numeral 50 indicates the uppermost.
Referring now to FIGURES 6-9 inclusive, a typical one of the triangular brace members is described and in particular, when taken with the previous description noted above. It is noted in FIGURE 6 that the semicir-cular portions at the top and the bottom of the triangular brace are identified by numerals 51 and 52 and that these semicircular portions are connected together by two side elements numbered 53 and 54, as noted in FIGURE 7. A
rigid element 55 has its opposite ends integrally formed with the intermediate portions 51 and an intermediate por-tion 56 located on the other side of the brace. Therefore, a complete triangle is provided with the intermediate por-tion 51, 52 and 56 integrally formed with the respectiive corners of the tria-ngle. The intermediate connecting elements 53, 54 and 55 give rigidity to the structure and may be reinforced by an integral rib such as indi-Gated by numeral 57.
All of the intermediate portions 51, 52 and 56 are of semicircular configuration in end view and are all aligned in parallel relationship with respect to the parallel axes 33 and 34 shown in FIGURE 6. Therefore, the elements 53, 54 and 57 are angularly disposed with respect to the axes 33 and 34. It is to be particularly noted that the angle is not perpendicular and that it is not a connection forming a right angle. Preferably, the elements 53, 54 and 55 are of the same length so that a complete isosceles triangleis defined as illustrated in FIGURE 8. With respect to the bottom view, as shown in FIGURE 9, a triangular relationship is again estab-lished by the angular arrangement of the elements 53, 54 and 55; however, the corner angles established by the elements are not equal. The base angles are equal but the upper angle as shown is substantially wider.
In view of the foregoing, it can be seen that a truss assemblage as shown in the drawings can readily be employed to build scaffolding or other type of plat-form structures in a rapid and convenient manner by using three basic components which are the tubular supports, the triangular braces and the coupling elements. Each of the respective braces may be formed by a molding or injected molding procedure and the tubular supports may be of common building stock. By providing a movable shoe in each of the couplings, a releasable fastening means is provided for attaching the respective corners of the braces to desired locations along the length of the three tubular supports. It is important to note that applied load forces which travel through the tubular supports are distributed evenly by means of the interconnecting braces, and particularly because the braces are formed with connecting elements that are at an angular dispos-ition with respect to the tubular supports on which they are mounted..
While particular embodiments of the present inven-tion have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this inven-tion.
A further object resides in providing a load-carry-ing structure composed of triangular brace members which include coupling flanges at i:he corners of each triangle so as to releasably connect with a run of tubular members so that load forces are transferred between adjacent brace members along the entire length of the construction for dissipation and transfer to other structures.
