Abstract
A speaker assembly rigging system is provided with a first frame and a second frame that is adapted to couple to the first frame. The system includes a cam and a link. The cam is pivotally connected to the first frame about a pivot point. The cam includes at least two cam surfaces, and each of the at least two cam surfaces are offset at a different radial distance from the pivot point corresponding to a splay angle. The link has a proximal end that is pivotally connected to the second frame and a distal end having a contact surface. The link extends from the second frame in a deployed position such that the contact surface engages one of the cam surfaces.
Claims20
A speaker rigging assembly comprising:
- a frame;
- a cam pivotally connected to the frame about a pivot point, with at least two cam surfaces, each of the at least two cam surfaces being offset at a different radial distance from the pivot point corresponding to a splay angle, with an intermediate surface between the at least two cam surfaces;
- and
- a link having a proximal end pivotally connected to the frame and a distal end having a contact surface, wherein the link extends from the frame in a deployed position to engage a cam surface of a cam of an adjacent speaker rigging assembly;
- wherein at least one of the frame and the link are adapted to be mounted to a speaker assembly.
A speaker array comprising:
- a first speaker assembly with a first speaker cabinet having laterally spaced apart first side surfaces;
- a first frame mounted to one of the first side surfaces;
- a first cam pivotally connected to the first frame about a first pivot point;
- a first link having a first proximal end pivotally connected to the first frame and a first distal end having a first contact surface formed therein;
- a second speaker assembly with a second speaker cabinet having laterally spaced apart second side surfaces;
- a second frame mounted to one of the second side surfaces;
- a second cam pivotally connected to the second frame about a second pivot point, wherein the second cam has at least two steps formed into a peripheral surface, each step being formed with an independent cam surface that is offset at a different radial distance from the second pivot point corresponding to a splay angle;
- and
- a second link having a second proximal end pivotally connected to the second frame and a second distal end having a second contact surface formed therein;
- wherein the first link extends from the first frame in a deployed position such that the first contact surface engages one of the steps of the second speaker assembly for orientating the first speaker assembly and the second speaker assembly at a splay angle therebetween corresponding to the step.
