Claim 1
Independent Claim
134 words
A board mount for mounting a board on a mounting surface comprising: a. a base plate for resting on the mounting surface; b. a brace rising from an upper surface of the base plate, the brace having: i. a slot for holding a corner of the board in the brace, and ii. a resilient strip formed on the back of the brace with: A. a locking pin on the lower end of the strip projecting forward into the slot, and B. a hook means on the lower end of the strip for allowing insertion of a tool therein to move the resilient strip and retract the locking pin from said slot; and c. an anchor descending from the underside of the base plate for inserting into a mounting hole provided on the mounting surface.
