Definitions

  • the invention relates generally to mechanical couplings and, more particularly, to a mechanical device, and associated method, adapted for coupling together two truss structures .
  • a drawback with such techniques is that, due to the large number of joints that must be coupled together in a typical structure, it is generally very time-consuming, and hence very costly, to assemble such a structure.
  • Furthermore, since such structures are, by their nature, temporary and must typically be disassembled a relatively short period of time subsequent to being assembled, substantial time must also be invested to decouple all such truss structures.
  • the present invention accordingly, provides a coupling device wherein a first truss may be coupled to a second truss by securing a male coupling portion of the coupling device to the first truss, and securing a female portion of the coupling device to the second truss.
  • An extension of the male coupling portion is positioned within an opening of the female coupling portion.
  • the extension is provided with a groove
  • the female coupling portion is provided with a lever having a cam formed on it, such that the lever may be rotated causing the cam to engage the groove and secure the male coupling portion to the female coupling portion, thereby securing together the first and second trusses.
  • FIGURE 1 is a perspective view of two truss structures coupled together using coupling devices embodying features of the present invention

  • FIGURE 8 is a cross-section of the coupling device of FIG. 6 taken along the line 8-8 of FIG. 6;
  • FIGURE 9 is a cross-sectional view of an alternate embodiment of the coupling device shown of FIGS. 4-5, the alternate embodiment having a hollow cross-section;
  • FIGURE 10 is a cross-section of the coupling device of FIG. 9 taken along the line 10-10 of FIG. 9;
  • FIGURE 11 is a cross-section of the coupling device of FIG. 9 taken along the line 11-11 of FIG. 9.
  • the reference numeral 100 generally designates a truss structure having a first truss 102 coupled to a second truss 104 utilizing coupling devices 106 embodying features of the present invention.
  • the trusses 102 and 104 generally constitute conventional trusses having a substantially square cross- section (i.e., in a horizontal plane as viewed in FIG. 1), though they may have other cross-sectional configurations, such as triangular cross-sections, trapezoidal cross- sections, cross-sections having sides of unequal length, and the like.
  • the trusses 102 and 104 may, furthermore, preferably constitute a portion of a larger truss structure, such as are commonly used in the theatrical and entertainment industry, or in scaffolding, where truss structures are assembled for a specific temporary use and then disassembled.
  • Each of the trusses 102 and 104 comprise four longitudinal tubular members 108 and various lateral members 110 which may be arranged in any of a number of different ways, well known in the art, and therefore will not be discussed in further detail herein, except insofar as necessary to describe the present invention.
  • the trusses 102 and 104 may be fabricated from any suitable material, such as metal (e.g., aluminum, steel), composite materials, and the like.
  • FIGURE 2 depicts the truss structure 100 wherein the trusses 102 and 104 are decoupled from one another.
  • the coupling devices 106 comprise a male coupling portion 202 and a female coupling portion 204.
  • the arrangement of male and female coupling portions is preferably alternated at each adjacent leg 108 (when there are an even number of legs) .
  • FIGURE 3 depicts, in an exploded view of the coupling device 106, various components thereof. Accordingly, the coupling device 106 comprises a male coupling portion 202 configured for matingly engaging a female coupling portion 204.
  • the male coupling portion 202 defines a shank 202a which is configured for fitting into a tubular portion 108 of the first truss 102.
  • An intermediate portion 202b extends from the shank 202a, and preferably defines a larger diameter than the shank 202a.
  • An extension portion 202c extends from the intermediate portion 202b, and preferably defines a smaller diameter than the intermediate portion.
  • a groove 202d is formed in the extension portion 202c, which groove is preferably curvilinear.
  • the female coupling portion 204 defines a shank 204a which is configured for fitting into a tubular portion 108 of the second truss 104.
  • a receiver end 204b extends from the shank 204a, and defines an opening 204c which is sized for receiving the extension 202c of the male coupling portion 202, as described in further detail below.
  • a lever 302 is configured for being pivotably secured, via a pin 304, to the receiver end 204b, and includes a cam portion 302a configured for engaging the groove 202d, as described in further detail below.
  • the lever 302 preferably also includes a locking mechanism 304, such as is described in U.S. Patent No. 6,053,540, to Meyer incorporated herein in its entirety by reference. Alternate techniques may be employed to lock the lever 302 in place, such as disclosed in U.S. Patent Nos. 4,647,075, 4,871,195, and 5,042,850, all of which are incorporated herein by reference in their entireties.
  • FIGURE 4 depicts how the coupling device 106 may be implemented to couple two trusses, it being understand the coupling device and method described herein may be used in any number of trusses, and is not limited to two trusses.
  • the shank 202a of the male coupling portion 202 is fitted in the tubular portion 108 of the first truss 102
  • the shank 204a of the female coupling portion 204 is fitted in the tubular portion 108 of the second truss 104, in any of a number of conventional manners, such as by shrink fitting, secured therein by bolts and nuts, • and the like.
  • the extension 202c of the male coupling portion 202 is positioned within the opening 204c of the female coupling portion 204.
  • the lever 302 is then rotated to lie adjacent to the receiver end 204b to thereby engage the cam portion 302a with the groove 202d, thereby securing the male coupling portion 202 to the female coupling portion 204, as also depicted in FIG. 5.
  • the trusses 202 and 204 may be decoupled by rotating the level 302 away from the receiver end 204b until the cam portion 302a is disengaged from the groove 202d, thereby permitting the male coupling portion 202 to be removed from the female coupling portion 204.
  • the present invention may take many forms and embodiments. Accordingly, several variations may be made in the foregoing without departing from the spirit or the scope of the invention.
  • the groove formed in the male coupling portion may be formed only as needed for enabling the cam member to engage the male coupling portion and secure same in the female coupling portion.
  • the cross-section of the extension 202c may be non-circular, and rather be defined for example by a square cross-section, as exemplified in FIGURES 6-8 via a truss structure 600, wherein members 608 and 610 (corresponding to members 108 and 110) of a first truss 602, and coupling portions 702 and 704 (corresponding to coupling portions 202 and 204) of a second truss 604, are configured having square cross-sections, and groove 702d is preferably formed on only one side of the coupling portion 702.
  • the male and female coupling portions may have hollow core portions to reduce weight of the coupling device 106, as exemplified in FIGURES 9-11 via a truss structure 900, wherein a male coupling portion 902 (corresponding to the male coupling portion 202) defines a hollow core portion 902a, and a female coupling portion 904 (corresponding to the female coupling portion 204) defines a hollow core portion 904a.
  • Ball and groove couplings, or pin and groove couplings may used in place of the cam and groove coupling described herein.

Abstract

Une première armature peut être reliée à une seconde armature par raccord d'une partie de raccord mâle d'un dispositif de raccord à la première armature, et par raccord d'une partie femelle du dispositif de raccord à la seconde armature. Une extension de la partie de raccord mâle est disposée dans une ouverture de la partie de raccord femelle. L'extension comprend une rainure, et la partie de raccord femelle est dotée d'un levier pourvu d'une came, si bien que le niveau peut pivoter et entraîner l'introduction de la came dans la rainure et la fixation de la partie de raccord mâle à la partie de raccord femelle, ce qui permet de fixer la première et la seconde armature ensemble.
