TITLE: ACCESSORY PLATFORM ASSEMBhY FOR A KAYAK
FIELD OF THE INVENTTON
The present izwention is dixected to an accessory platform for attachment to a kayak, in particular to an accessory platform which can be moved from an open to a closed position to allow for access to the kayak deck in the open position.
BACKGROUND OF THE INVENTION
Kayaks have long been used for transporting people as they are highly manoeuvrable, however kayaks generally do not have a large amount of storage space. Zt is also not easily possible to bring along pets, such as dogs, in a kayak, especially a sea kayak having a closed cockpit. as there is no place for the animal to be safely placed. in addition, kayaks are not easily adaptable for other uses such as being used as a platform fax' swimming, diving or fishing.
There hare been many attempts in the past to increase the versatility of a kayak by providing accessories for the kayak. For example, US patent 5,457,930 issued October l, 2002 to Drabkin describes a sail kit for a kayak to adapt the kaye~k to a sailing vessel. Various versions of paddle holders have been described in for example US patent 6,027,387 issued February 22, 2000 to Allin, US patent 6.632,111 issued October 14, 2003 to Oathout and US patent 6,755,195 issued June 29, 2004 to Bolebruch. aS patent _]_ 6,050,213 ,issued April 18, 2000 to Stevens describes a beverage holder for a kayak and US patent 5,996,527 issued December 7, 1999 to Ambrozic describes a fishing rod holder for a kayak. US patent 5,243,928 issued September i4, 1993 to ~renamen describes cargo racks for mounting on opposed sides of the cockpit opening on a kayak to mount cargo on a kayak When limited cargo space is available within the kayak. These racks include pairs of rail members mounted to support posts to fixedly secure the rails relative to the deck of the kayak.
Outrigger stabilizer floats for kayak are also available such as for example, outrigger stabilizer floats available from Castle Kraft in Illinois, Easy Rider of Seattle, Washington and a Tribalarice available from Tribal Kayaks of Villa Hills, kCentucky.
There however still remains the need for an accessory for a kayak to enable a platform to be mounted on the kayak on top of the deck and which optionally may include an outrigger for increasing stability of the kayak.
