Patent ID: 7021221

Claim:
A holding device comprising: a corner bracket having first, second, and third openings; a first elongate base member having a proximal end secured within said first bracket opening and a distal end opposite the proximal end; a second elongate base member having a proximal end secured within said second bracket opening and a distal end opposite the proximal end, said first and second elongate base members extending perpendicular to one another; each of said first and second elongate base members having an upper surface and a lower surface opposite the upper surface, said lower surface adapted to engage a support surface; a first sliding member slidingly engaging the upper surface of said first base member and slidable along its length; a second sliding member slidingly engaging the upper surface of said second base member and slidable along its length; a first fastener engaging said first sliding member and said first base member, said first fastener manually operable to selectively secure said first sliding member and said first base member in fixed relative position and alternately to release said first sliding member and said first base member to permit sliding movement of said first sliding member relative to said first base member; a second fastener engaging said second sliding member and said second base member, said second fastener manually operable to selectively secure said second sliding member and said second base member in fixed relative position and alternately to release said second sliding member and said second base member to permit sliding movement of said second sliding member relative to said second base member; each of said first and second base members having a slip-resistant material disposed on the lower surface thereof; a first arm attached to the first sliding member and elevated above the support surface, said first arm having a first peripheral edge surface which is parallel to an aligned facing surface of said first base member and a second, gripping peripheral edge surface having a slip-resistant material thereon; and a second arm attached to the second sliding member, said second arm elevated above the support surface and extending parallel to the first arm, said second arm having a first peripheral edge surface which is parallel to an aligned facing surface of said second base member and a second, gripping peripheral edge surface having a slip-resistant material thereon, said second arm second gripping surface in parallel and facing relation to said first arm gripping surface, wherein sliding movement of one or both of said first and second sliding members causes parallel relative movement between said first and second arms.
