Definitions

  • a coupling in accordance with the present invention comprises a carrier upon which any desired number of U shaped links may be mounted; each link freely embraces the carrier, a solid body fixed, or adapted to be fixed, to one end of a structral member is assembled between the free ends of the link arms, a sleeve encircles and is slidable lengthwise of the arms and a wedge which extends between the arms, carrier and sleeve, is adapted, when driven in the appropriate direction relatively to the link, to force the sleeve away from the carrier into abutment with the body and/ or structural member so that the link is tensioned and, when the structural member is assembled in a structure by couplings assembled to its opposite ends, the member is placed in compression.
  • This invention relates to couplings primarily intended to be used for connecting tubes, bars and analogous structural members in frameworks, particularly geodetic frameworks wherein, at each of certain positions, the adjacent ends of several such structural members are connected together so that the members extend from the position in different directions.
  • a coupling comprises a U-shaped link which embraces a carrier, a rigid body which is, or is adapted to be, fixed to one end of a structural member and is detachably assembled to and between the free ends of the link arms, a sleeve which encircles and is slidable lengthwise of the link arms, and a wedge which extends between the arms carrier and sleeve, and is adapted, when driven in the appropriate direction relatively to the link, to force the sleeve away from the carrier into abutment with the body and/ or the structural member.
  • FIG. 1 is a plan of a coupling constructed in accordance with one typical embodiment of the invention.
  • FIG. 2 is a section along the line IIII, FIG. 1.
  • FIG. 3 is an exploded view of certain parts of the coupling.
  • FIG. 5 is a part sectional elevation of an assembled but unlocked coupling constructed in accordance with an alternative embodiment of the invention.
  • the neck is forced against the said inclined faces as the sleeve 4a is forced against the solid body.
  • the narrower end of the wedge is provided with a stem which is offset from the longitudinal centre line of the wedge and has, at its free end, a head 7c of such dimensions that it is unable to pass through the space between the link arms; hence, when the coupling is unlocked, the wedge is retained in the assembly but, when turned through about its lingitudinal centre line to the position shown in dotted lines in FIG. 5, the sleeve may be moved toward the closed end of the link to permit the neck 14a to be disengaged from, or engaged with, the open-ended pocket.
  • each of two opposed faces of the body neck is provided with a transverse flange which engages with a channel formed in a corresponding one of the adjacent faces of the link arms.
