ABSTRACT:
This application is concerned with an improved deck board fastener which, when installed, is hidden from the deck surface.
BACKGROUND OF THE INVENTION
My U.S. Pat. Nos. 5,738,473, 5,927,923 and 6,071,054 disclose a deck board fastener in the form of a three prong staple. An improved three prong staple particularly adapted for installation with a fastener feeding and driving tool is disclosed herein.
BRIEF SUMMARY OF THE INVENTION
A principal feature of the improved staple fastener is that it has first and second parallel prongs for insertion respectively into a deck board and a supporting joist, a crown joining the first and second prongs and a third prong extending from the crown at an angle to the first prong for securing another deck board on the joist adjacent the first deck board, the crown having a driving surface in the plane of the parallel prongs.
Another feature is that the driving surface of the crown is at a right angle to the length of the first and second prongs.
A further feature is that the axes of the first and second prongs extend through the driving surface.
Another feature is that the angle of the third prong is at the driving surface edge of the crown.
Yet a further feature is that in driving the staple a driving force is applied to the driving edge of the crown, in the plane of the parallel prongs and a right angle to the driving surface.
Yet another feature is that the staple is manufactured from a flat blank by bending the third prong out of the plane of the crown and first and second prongs along the edge of the crown.
