A suspension system for a speaker line array is provided with a base to mount to a first speaker cabinet. A rail extends transversely from the base. A bar is mounted relative to the rail between a stowed position and an extended position, wherein the bar is biased away from a central portion of the base to the extended position to contact another speaker or a support. A locking mechanism is driven by a transmission to lock the bar in the stowed position.

Suspension system locking mechanism

A method for installation of a line array of speaker assemblies is provided. At least two stacked speaker assemblies with suspension systems are provided. An installation splay angle between the at least two stacked speaker assemblies is selected, while the two stacked speaker assemblies are oriented at an initial splay angle. The suspension system of an uppermost speaker assembly of the at least two stacked speaker assemblies is connected to a support. The support is raised to lift the at least two stacked speaker assemblies, whereby the at least two stacked speaker assemblies pivot from the initial splay angle to the installation splay angle and form a line array.

Suspension system mechanism

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.

Rigging system for speakers

A speaker assembly is provided with a cabinet with laterally spaced apart side surfaces and a frame mounted to one of the side surfaces. The speaker assembly is also provided with a lever arm and a ratchet mechanism. The lever arm has a proximal end to connect to an upper support, a distal end with a plurality of teeth extending radially outward, and an intermediate portion pivotally connected to the frame for adjusting a splay angle of the cabinet relative to the upper support. The ratchet mechanism is coupled to the frame with at least two pawls each individually biased to engage at least one of the plurality of teeth to allow pivotal motion of the lever arm relative to the frame in a first direction and limit pivotal motion of the lever arm in a second direction that is opposite the first direction.

A suspension system is provided with a frame to mount to a side surface of a speaker cabinet with a plurality of apertures formed therethrough. The suspension system is also provided with a lever arm with a proximal end and a distal end that are both adapted to connect to an upper support. The lever arm also has an intermediate portion that is pivotally connected to the frame about a pivot axis with a plurality of arcuate slots formed through. Each arcuate slot is formed with an end stop that corresponds to a splay angle of the speaker cabinet relative to the upper support, and each slot aligns with one of the apertures to receive a pin. Whereby suspending the speaker cabinet from the upper support pivots the lever arm in a first direction until the pin engages the end stop.

A speaker rigging system is provided with a frame, a cam pivotally connected to the frame about a pivot axis and a sector secured to the cam with a peripheral surface with a plurality of teeth formed therein. The speaker rigging system also includes a lever arm and a pawl. The lever arm is pivotally connected to the frame with a proximal end and an intermediate portion extending between the proximal end and the pivotal connection to be oriented proximate to the sector. The pawl extends from the intermediate portion of the lever arm and is spring-biased toward the sector for engaging one of the plurality of teeth to lock the cam to the frame in a locked condition.
