Description

FIELD OF THE INVENTION

This invention is in the field of paddles convertible to other diverse uses.

BACKGROUND OF THE INVENTION

Kayak paddles are well known as comprising a pole supporting on each end a paddle. The paddles may be aligned with each other or rotated to be at a relative non parallel angle, for example perpendicular angles. However, a paddle is a single use device, for example, in the sport of kayaking it is not adaptable for other activities. Currently, most existing paddles fall into one of two categories, either they are durable but are quite heavy and bulky, or they are lightweight but compromise ease of use, durability, and function. The paddle, when not in use, must be carried and the trekking pole, when not in use, must be stored.

Over recent years there has also been a dramatic increase in people carrying collapsible kayaks or lightweight rafts in their backpacks (called pack rafting). These users are very weight conscience, since they frequently travel many miles with all their equipment on their backs.

Many of them are carrying both a paddle and a trekking pole.

Trekking poles are widely known and used by the outdoor community as useful walking tool to reduce fatigue and increase stability of the user.

While the advantage of using a trekking pole is widely recognized, a pack rafter, considering the amount of weight and the distance the pack rafter may be required to haul that weight, choices will be forced on the pack rafter, and a comprise will be made between one or more necessary hiking tools. As a result, the pack rafter may necessarily be prevented from taking a trekking pole and could experience fatigue or be forced into trekking distances made shorter by the lack of a trekking pole.

SUMMARY OF THE INVENTION

The Trekking Paddle is primarily used for activities where a user will hike for a certain distance and then inflate or assemble a watercraft that requires a paddle for propulsion. The Trekking Paddle saves weight and space by combing two frequently used devices for such activities: a trekking pole and a paddle. This product appeals especially to the growing number of pack rafters, backcountry kayakers, and portaging canoeists who go on treks where travel alternates between land and water.

The invention, as shown and described according to a disclosed preferred embodiment, offers the pack rafter the advantage of kayak paddle which is convertible into a trekking pole. When converted, the paddle and its weight virtually disappear, becoming a trekking pole, useful in making the journey more comfortable and less fatiguing.

When the pack rafter is ready to reenter the watercraft, the trekking pole converts to a paddle, and the trekking pole virtually disappears, and at the same time, leaving storage space in the kayak, where the trekking pole would have otherwise been placed.

As disclosed in a preferred embodiment, the trekking pole sections may be rearranged, removing certain parts useful only in a trekking pole and adding paddle blades. By converting the paddle into a trekking pole and the trekking pole back to a paddle, the necessity for carrying two separate devices, each useful for a respective and disparate purpose, is eliminated.

As shown in a preferred embodiment, according to the disclosed inventive principles, a kayak paddle is made of 3 pole sections and 2 paddle blades. In the paddle mode, a middle pole No. 2, is axially interlocked and axially coupled to two outer poles Nos. 1 and 3, respectively. The two outer poles Nos. 1 and 3 each have a hand grip, respectively, as would be known to those skilled in the art. The outer ends of pole Nos. 1 and 3, are each interlocked and axially coupled to a paddle, completing the paddle assembly,

In converting the kayak paddle to a single paddle, pole No. 1 is detached and a handle is interlocked and axially coupled to its open end, opposite the paddle.

In converting the kayak paddle or the single paddle, to a trekking pole, pole No. 3 is removed and a cap is axially joined to the end closest to the grip. Pole No. 1 is interlocked and axially coupled to the open end of pole No. 3, with the grip on pole No. 1 arranged closer to pole No. 3. Pole No. 2 is interlocked and axially coupled to the open end of pole No. 1 and a tip is inserted into the open end of pole No. 2 to complete the trekking pole. Tip 26 is interlocked and axially coupled to pole No. 2.

In a preferred embodiment, the poles may be interlocked and axially coupled by threaded joints, twist locks, or by spring locks, for example, spring loaded studs on one pole, interlocking with matching holes on a coupling joint, used on an adjoining pole.
