Description

PRIORITY STATEMENT

This application claims priority to U.S. Provisional Application No. 60/641,928, entitled “Surfboard Drain and Leash Plug” filed on Jan. 6, 2005, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

The thrill of riding a surfboard along an ocean wave has been experienced by many people. At the conclusion of any given ride on the surfboard, the surfer eventually dismounts the surfboard. In most cases, the surfer dismounts the surfboard into the water near the shallow water amid the waves break long on the shore. The surfer maintains control over the location of the surfboard through the use of a leash attached to the surfer and to a portion of the surfboard. The leash prevents the surfboard from getting washed away from the surfer in the rough surf

The leash can consist of a cord having a strap (e.g., a leg strap) for attachment to a part of the surfer, such as an ankle, as well as a portion for attachment to the surfboard opposite the leg strap. The leash cord can be a plastic cord having about a 3/16 inch to about a ⅜ inch diameter and a length of about 4 to 12 feet and at the end near the surfboard a leash rope or line about ⅛ inch in diameter and about 8 to 10 inches in length extends from the plastic cord to a leash attachment. The cord attaches to the surfboard at the leash attachment. The leash attachment can comprise a loop formed on the deck of the surfboard. The loop can consist of a cured resin and fiberglass m Another style of leash attachment can include an attachment point formed by a hole in the head of a screw that fastens the rear fin to the surfboard Another alternative design for the leash attachment includes a leash plug.

The leash plug includes a pre-molded plastic body that can be installed in the surfboard. The leash plug permanently attaches to the surfboard and provides a secure location to tether the leash cord to the surfboard. Many surfboards comprise a mostly solid lightweight core covered with a smooth watertight deck material. The conventional leash plug can be fitted into an orifice through the deck material and into the core.

Alternative surfboard designs have included relatively hollow hulled surfboards with a hardened deck material enclosing an interior cavity with open-celled support structures. These hollow hulls allow for a lightweight design having excellent hydrodynamic properties for surfing performance. These hollow hulled vessels can include a vent and/or drain (hereinafter “vent/drain”). The vent/drain is a penetration through the hull creating a passage for air and water to pass from the interior of the hull to the exterior of the hull. The water and air pass through the vent/drain in order to equalize the air pressure inside the hull to the atmosphere due to changes in elevation and temperature. The vent/drain also allows for water to drain from within the hull, since not all watercraft are perfectly watertight. The vent/drain includes a vent/drain plug designed to seal or unseal the hull for venting and draining.

The prior art hollow hull surfboards require both a vent/drain plug as well as a leash plug. The need for both the vent/drain plug and leash plug requires that the surfboard hull include two penetrations to support both the vent/drain plug and the leash plug. The hollow surfboards often experience leakage at the penetrations due to seal failures as well as improperly fit plugs. The greater number of penetrations results in increased unwanted leakage into the hollow cavity of the surfboards. With all hollow hulled watercraft it is important to limit the number of penetrations through the hull into the interior hollow cavity.

What is needed in the art is a device that reduces the amount of penetrations through the surfboard hull while providing the necessary utility of venting, draining and leashing.
