Deck board fastener

Abstract

According to the present invention, a fastener for securing a first board to an underlying supporting member and to at least one other board running adjacent and parallel to the first board. The fastener includes a body portion, at least one first prong, at least one second prong, and a flange. The at least one first prong extends outwardly from the body portion for driving into a first board. The at least one second prong extends outwardly from the body portion for penetrating a second board. The body portion of the fastener includes an opening for receiving a connector. When installed, the connector passes through the opening in the body portion and into the supporting member, which supports and underlies the first and second boards. The flange extends outwardly from the body portion in order to maintain a desired gap between the first and second boards.

Description

FIELD OF THE INVENTION [0001] The invention concerns a deck fastener for securing deck boards together and to a supporting member, and deals more particularly with a deck fastener that does not protrude from the deck surface. BACKGROUND OF THE INVENTION [0002] Brackets, clips, and anchors for securing boards to joists without nail or screw heads protruding from the deck surface are known. However, some of these deck-fastening systems require securing devices that are difficult to install or require extensive preparation. For example, some deck fastening systems require pre-installing tracks on joists, pre-drilling slots or holes in boards for fasteners, or gluing the boards to the joists. Other deck fastening systems must be installed from below the deck, a time consuming, expensive, and sometimes impossible procedure. [0003] While these deck-fastening systems are designed to prevent nails or screws from appearing on the deck surface, many of the parts of the systems are quite appar...

AI Technical Summary

Benefits of technology

"The present invention is a fastener for securing two boards to a supporting member. The fastener has a thin flat body with two prongs that penetrate the boards. A flange extends from the body and is used to space the body away from the supporting member. The fastener has an opening for receiving a connector, which holds the fastener in place. The third prong helps to space the body away from the supporting member during installation. The conical shape of the opening allows for close positioning of adjoining boards. The technical effects of the invention include improved stability and secure mounting of boards to a supporting member."

Problems solved by technology

However, some of these deck-fastening systems require securing devices that are difficult to install or require extensive preparation.

Other deck fastening systems must be installed from below the deck, a time consuming, expensive, and sometimes impossible procedure.

Therefore, the display of protruding fasteners and / or other components is unsightly and possibly dangerous.

Since deck boards are subject to warping, splitting and shrinking, some of the known deck fastener systems do not prevent the deck boards from separating from the support joists over time.

The fasteners also can come loose or become out of position on the joists.

The separating of the boards from the joists may allow the boards to protrude above the deck surface, making the deck unsightly and less usable.

However, wide prongs have been found to have a tendency to split the deck board material, especially when the deck board material is a composite material.

In addition, thermal expansion and contraction of the boards has caused damage to the deck boards, the support member and / or the deck fastener.
