Claims
- 1. A system for mounting a speaker cabinet having at least one planar surface to at least one planar structural support surface comprising:
- a plurality telescoping struts, each strut including two mutually extensible members and means for releasably positively fixing the relative extension of the members;
- a plurality of flanges, each flange fixed to one end of a strut and having at least one planar surface including a two dimensional array of apertures for receiving a plurality of fasteners to mount the strut the said at least one planar structural support surface;
- a plurality of brackets, each bracket pivotably mounted to the other end of a strut and having at least one planar surface including a two dimensional array of apertures for receiving a plurality of fasteners to mount the strut to the at least one planar surface of the speaker cabinet; and
- means for releasably fixing the pivotal position of each bracket relative to the strut to which it is mounted;
- whereby the inclination and proximity of the speaker cabinet relative to the at least one planar structural support surface can be altered by cooperatively adjusting the relative extension of the members and the relative pivotal positions of the brackets.
- 2. A system according to claim 1 wherein the means for releasably positively fixing the relative extension of the members of each strut comprises a first set screw threadably engaged in the outer member of the members adjacent one end thereof and adapted to engage the inner member of the members on demand, the inner member including a plurality of annular grooves adapted for engagement with the first set screw for positive engagement.
- 3. A system according to claim 2 comprising a second set screw threadably engaged in the outer member offset from the first set screw.
- 4. A system according to claim 1 wherein each bracket comprises a second planar surface having a pivot hole and a plurality of mounting holes disposed in an arc about the pivot hole and a pair of bolts through the pivot hole and a selected one of the mounting holes, respectively, to positively mount the bracket to the other end of a strut at a selected angular orientation.
- 5. A system according to claim 1 wherein each flange includes a central planar portion normal to the axis of the strut to which the flange is fixed, the central portion having opposed parallel lateral edges and a pair of planar side portions fixed to the central portion at the respective lateral edges at a substantially 45 degree angle so that the respective side portions have an included angle of 90 degrees, the side portions each having a plurality of apertures for receiving a plurality of fasteners to mount the strut to a corner structural support having two perpendicular planar structural support surfaces.
