The present invention relates to truss structures and truss assemblies utilized in scenes for shows (such as live performances, events and other stages), particularly in scenes for supporting equipment such as lighting and audio devices. More specifically, the disclosed invention is a truss assembly made of a truss structure and reinforcement members (20, 22, 24, 26), adapted to be assembled on the side surfaces thereof, to enhance rigidity and to resist torsion or shearing forces of the truss structure, and the resulting reinforced truss structure once assembled.
The truss structure (10) comprises an elongated frame with four sides and two opposite ends (altogether forming a rectangular prism), at least some, and preferably all of the sides comprising a reinforcement member. These reinforcement members, embodied as plates of a single component, cover a substantial portion of the truss sides, preventing torsion or shearing forces. Recesses (28) along the longitudinal edges (30) of each reinforcement member provide clearance that allows for secure attachment of pieces of equipment to the truss structure (10) without conflicting with the presence of the reinforcement member on the side of the truss structure (10) on which such pieces of equipment are being secured.
Referring to
These reinforcement members provide planar (i.e., flat) surfaces covering a substantial portion of the sides of the truss structure (10). According to a preferred embodiment, the reinforcement members are planar surfaces covering almost the complete side surface of the portion of the face (12, 14, 16, 18) of the truss structure (10).
In
When installed over scenes such as scenes or stages used for shows, events, promotional events and the like, the reinforced truss structure (10) provides enhanced stability and resistance to torsion or shearing forces. The load (maximum weight) that the reinforced truss structure (10) can hold without breaking is considerably and significantly enhanced by having the reinforcement members (20, 22, 24, 26) attached to the sides of the truss structure (10). Pieces of equipment can be securely attached to the truss structure (10) using the small recesses (28) along the edges of the reinforcement members.
Advantages include increased rigidity and stability of the truss structure; increased resistance to torsion and shearing forces when compared to a prior-art truss structure exempt from any reinforcement as disclosed herein; and the presence of secure attachment points for securing pieces of equipment without compromising structural integrity since permitted by the recesses (28) on the edges of the reinforcement members or plates (20, 22, 24, 26).
It should be noted that the invention according to the present disclosure is also applicable as trusses of other shapes, including 2D trusses being made of a single panel and a single corresponding reinforcement member covering the only surface thereof, and of triangular prism truss including three longitudinal chords.
It also should be noted that the reinforcement members may be combined with or can replace at least a portion of the link chords connecting adjacent longitudinal chords to which can be permanently or releasably attached a reinforcement member.
According to an embodiment (not depicted), a truss structure comprises four reinforcement members (20, 22, 24, 26) coupled to longitudinal chords, and at least a plurality of link chords (115, 117) coupling non-adjacent longitudinal chords and ensuring robustness of the rectangular prism shape of the truss structure (10) against deformation.
In a preferred realization, the reinforcement members (20) are secured when manufacturing the truss. The reinforcement members (20) are secured with rivets to the longitudinal chords, and to diagonal chords coupling neighbor mains chords. Preferably, reinforcement members are also secured with rivets to the orthogonal link chords coupling orthogonally the longitudinal chords about the extremities of the truss (10).
According to alternative embodiments, reinforcement members may be releasably secured thereto, or permanently secured to one or more of the components recited before, e.g., welded thereto. According to alternative embodiments, e.g., embodiment illustrated through
It is worth mentioning that based on embodiments, embodiments of truss structures may comprise one or more reinforcement members, with the reinforcement members being mounted to or in combination with link chords coupling adjacent chords. The reinforcement member(s) may be permanently coupled or releasably coupled to the chords. Cross-link chords may be used to couple non-adjacent longitudinal chords.
Number of recesses of the reinforcement members is at least two per edge, and preferably more such as six per edge. Ratio of length of recesses over length of the edge available for coupling to the chords is above 1.25:1, preferably over 1.5:1, and more preferably between 1.75:1 to 1.8:1.
Reinforcement members can undergo modifications, including—the length of the reinforcement members relative to the length of the longitudinal chords; —number, size and positions of the recesses along the edges of the reinforcement members; —presence/absence of openings (not depicted) in the reinforcement members; and —alternative methods to secure the reinforcement members to other components of the truss structure.
Referring to
The presence of the at least one and preferably two flat sides (132, 133) ensures that the soldering or brazing of the link chords (113, 115, 117, 119) of the truss structure (10) or other pieces of equipment to the longitudinal chords (13, 15, 17, 19) is facilitated, whether for manual or robotized soldering or brazing. Having a remainder of the longitudinal chord (13) (or longitudinal chord 15, 17, 19) having a circular cross section (being otherwise cylindrical) outside of the flat sections (132, 133) ensure that typical pieces of equipment can be clipped or secured to the cylindrical longitudinal chords (13) as usual thanks to the fact the flat sections (132, 133) do not occupy a whole periphery of the longitudinal chords nor protrude to the general cylindrical profile (135) of the longitudinal chords (13). Having flat section(s) (132, 133) around the otherwise cylindrical longitudinal chords or other piece(s) (link chord(s), etc.) has been found to be a proper trade-off between computability, or ability to clamp pieces of equipment onto the cylindrical portion, and ease of soldering on flat portions.
While preferred embodiments have been described above and illustrated in the accompanying drawings, it will be evident to those skilled in the art that modifications may be made without departing from this disclosure. Such modifications are considered as possible variants comprised in the scope of the disclosure.
