Attaching device

An attaching device for securing a first support element with a first surface, a second surface substantially parallel to said first surface and a third surface disposed between said first and second surfaces to a second support element disposed substantial perpendicularly relative to said first support element, said first support element having a medial portion and end portions;

• said device comprising a base member having a first section for disposition adjacent the first surface of said first support element, and a second section extending angularly from said first section for engaging the third surface of said first support element, said second section including an offset portion for disposition adjacent the second surface of said first support element;
• a first cam means adjustably mounted on said first section of said base member and extending angularly therefrom, said cam means being in spaced relation with said base member second section and when in one position of adjustment coacting with said base member second section for assembling said attaching device on the medial portion of said first support element and when in a second position of adjustment coacting with said base member second section for dissembling said attaching device from said first support element medial portion, said assembly and disassembly effected by lateral rather than endwise relative movement of said attaching device with respect to said first support element;
• and a second cam means adjustably mounted on the base member first section for securing said second support element in a position substantially perpendicular to said first support element, said first and second cam means being disposed on opposite sides of said base member first section, said second cam means when in one position of adjustment coacting with said base member first section for wedging therebetween a selected portion the second support element;
• both said first cam means and said second cam means being provided with means for effecting independent adjustment thereof, each cam means is rotatably adjustable about an independent axis, said independent axes being angularly disposed relative to one another.
