Filed:

Jan 13, 2005

Appl. No.:

11/035676

Inventors:

John Monitto - San Rafael CA, US
John McGhee - Parkdale OR, US
Dean Marshall - San Rafael CA, US

Assignee:

Meyer Sound Laboratories, Incorporated - Berkeley CA

International Classification:

H04R 25/00

US Classification:

381386, 381 87, 381335

Abstract:

A side frame for a loudspeaker rigging system has a frame structure mountable to the side of a loudspeaker, and links associated with the frame structure for linking together the corners of the frame structures of vertically adjacent side frames. The links associated with each side frame structure include a pivot link and splay adjustment link, each of which has a top extended end and a base end with a seating edge. Guide channels, which are located in the top corner regions of the frame structure to receive the base ends of a pivot link and splay adjustment link associated with a vertically adjacent side frame, have seating surfaces that conform to the seating edges at the base ends of the pivot and splay adjustment link. When base ends of these links seat in the guide channels, pin holes in the base end of the links self-align with pin holes in the corners of the frame structure for easy insertion locking pins. The extended end of the splay adjustment link further includes at least two, and preferably an array of pin holes which can selectively be matched with one pin hole within a row of pin holes in a bottom corner region of the side frame to permit adjustments of the splay angle over a range of angles.

Abstract:

A side frame for a loudspeaker rigging system has a frame structure mountable to the side of a loudspeaker, and links associated with the frame structure for linking together the corners of the frame structures of vertically adjacent side frames. The links associated with each side frame structure include a pivot link and splay adjustment link, each of which has a top extended end and a base end. Stow channels, which are preferably located in the bottom corner regions of the frame structure, contain the pivot link and splay adjustment link in the frame structure. A gripping structure associated with at least one, and preferably each link of the pivot and splay adjustment links allows a user to easily maneuver a link from its stowed to its deployed position. The extended end of the splay adjustment link includes at least two, and preferably an array of pin holes which can selectively be matched with one pin hole within a row of pin holes in a bottom corner region of the side frame to permit adjustments of the splay angle over a range of angles. Suitably, two rows of pin holes are provided in the top extended end of the splay adjustment link to permit multiple and incrementally small splay angle adjustments.
