Abstract
A cart assembly is provided for transporting multiple loudspeakers that are stacked in a pre-assembled line array. The cart assembly includes a base and at least two wheels that are mounted to the base. A plurality of loudspeakers having a non-parallelogram cabinet are stacked on the base in a vertical line array with a splay angle between a pair of axis each extending through about a horizontal axis between adjacent loudspeakers. The cart assembly is coupled to at least one of the plurality of loudspeakers. The cart assembly and the plurality of loudspeakers arranged in the vertical line array are transported to a desired location.
Claims17
A cart assembly comprising:
- a first base and a second base that are laterally spaced apart from each other to collectively support at least one loudspeaker cabinet;
- a subframe extending between the first base and the second base;
- at least two wheels mounted to each base;
- a support extending from each base away from the at least two wheels;
- and
- a locking mechanism coupled to the support to selectively engage the loudspeaker cabinet, the locking mechanism being mounted for translation relative to the support between an engaged position and a released position.
A cart assembly comprising:
- a base to support a loudspeaker cabinet array;
- an upright frame with a proximal end connected to the base and a distal end spaced apart from the proximal end and adapted to pivotally connect to at least one loudspeaker of the loudspeaker cabinet array;
- and
- at least one strut providing a translational connection between the loudspeaker cabinet array and the upright frame to allow adjustment of an azimuth angle of the loudspeaker cabinet array about the pivotal connection relative to an upright axis.
A method of transporting a plurality of loudspeakers, comprising:
- providing a cart assembly having a base, and at least two wheels mounted to the base;
- stacking a plurality of loudspeakers having a non-parallelogram cabinet on the base in a vertical line array with a splay angle between a pair of axes each extending through adjacent loudspeakers;
- coupling the cart assembly to at least one of the plurality of loudspeakers;
- adjusting a splay angle between vertically adjacent loudspeakers while the plurality of loudspeakers is supported by the cart assembly;
- and
- transporting the cart assembly and the plurality of loudspeakers to a desired location.
