DESCRIPTION OF THE DISCLOSURE

A user on a recreation watercraft such as a paddleboard may switch from a standing position to a kneeling or sitting position, depending on the conditions, for example. In a standing position, the user paddles with a long paddle having a handle on one end and a blade on the other end. In a seated or kneeling position, such a paddle can be cumbersome and inefficient to use. In that situation, a double paddle would be more desirable to use. However, for many users on most recreational watercraft that are mostly paddled, stowing two paddles is undesirable. Similarly, bringing along a double paddle attachment may be inconvenient because, if remembered, it can fall off the watercraft (or would have to be secured in some way that could interfere with the use of the watercraft).

Thus, there is a need for a self-contained paddle that can be adjusted from a single paddle form with a handle on one end to a double paddle configuration having blades on both ends. The paddle of the present invention allows for the end of the shaft having the handle to transform to a second blade, forming a double paddle without the need to bring a separate attachment during an outing and without interfering with the use of the paddle in the single paddle configuration when the paddle is in the single paddle configuration.

The paddle includes a single paddle configuration as shown in FIG. 1A. Paddle 100 includes a shaft 102 having a lower shaft 103 and an upper shaft 105. Lower shaft 103 and upper shaft 105 may be slidably engaged to allow for the adjustment of the overall length of shaft 102. A first blade 104 is on one end of lower shaft 103 and a handle 108 on one end of upper shaft 105. Handle 108 may be loosened from the end of upper shaft 105 and extended outwardly revealing an embedded inner shaft 112 which has a second blade 116 attached in a compressed state (as shown in FIG. 2A) that can be placed in an unfurled state to form a double paddle configuration as shown in FIG. 1B. Inner shaft 112 may be cylindrical with an opening running along one side, such as a ½ or ¾ cylinder (as best seen in FIG. 2A), which houses a folded or compressed second blade 116 when in a stowed position, as when inner shaft 112 is within upper shaft 105. Inner shaft 116 may be secured in the extended position by any suitable mechanism, such as a hole 120 for receiving a depressible securing knob 124. Once inner shaft is extended and secured in the extended position, second blade 116 may be unfurled and secured into a blade form. Preferably, a rod 114 or other support member may be attached to an inner portion of inner shaft 112, such as by rivets 121 (e.g., 121A-121C as shown in FIG. 3). In an embodiment, second blade 116 may be made of woven fabric or other suitable material with a plurality of supports 128 (e.g., 128A-128B) at intervals for added rigidity.

Turning to FIGS. 2B-3, a first edge 115 of second blade 116 is attached, such as by a sewn seam, to rod 114 and a second edge 117 is attached, such as by a sewn seam, to an outer edge support member 132. Outer edge support member 132 is pivotably attached to rod 114 or inner shaft 112 at a pivot point 44 and may include a pivotably attached blade support 136 that is attached on one end to the distal end of outer edge support member 132 and can be pivoted around pivot point 119 so that blade support 136 extends along an outside edge 113 of second blade 116 and engages, via a female snap 142 or other suitable mechanism, with a male snap 140, socket, or other suitable receptor on inner shaft 112 that can reversibly secure the other end of blade support 136 in position to maintain second blade 116 in an unfurled configuration. Other securement mechanisms may be used to maintain second blade 116 in a blade shape for use when paddle 100 is in the double paddle configuration.

In this way, a single ended long paddle for a “standup” paddleboard has an extendable shaft with an enclosed second blade that can be deployed so that the paddle becomes a double paddle. Note that the shaft of the paddle may also be adjustable in length, which is beneficial for both single paddle uses and double paddle uses.

The adjustable handle at the end of the single paddle configuration allows for standard use of single long paddle with handle, which can be converted to a double ended paddle by unlocking shaft and extending secondary blade, which was folded inside shaft. Once secured in place this would allow for double ended use. To transform back to a single paddle configuration, the securement mechanism would be released and the flexible material folded back into main shaft and the handle resecured in place at the end of the shaft.

The folded webbing used for the collapsible and stowable secondary blade may be made of various materials in addition to a woven fabric such as rip stop nylon or a plastic with a frame and support stays of aluminum or any other suitable light and supportive material.

Exemplary embodiments have been disclosed above and illustrated in the accompanying drawings. It will be understood by those skilled in the art that various changes, omissions, and additions may be made to that which is specifically disclosed herein without departing from the spirit and scope of the present invention.
