Paddle Shaft Horizontal:

In one embodiment a high tech aluminum, Carbon Fiber, or other material, paddle horizontal shaft (20) is used to cut down on weight and increase strength over existing designs and more accurately simulate a true kayak paddle. There will be an indexing grip incorporated on one side of the horizontal shaft (36). This assembly includes a trans catch assembly that enables the user to increase the resistance or reduce the resistance of the horizontal shaft to simulate various kayaking scenarios. This is achieved by the adjustment knobs located on this assembly. (22)

Base:

In one embodiment a low-pressure injection or other materials such as wood or molded base is used as a platform for mounting all other components to (12). The platform has rails on both sides (46) that serve as adjustment points for the seat (14) and footrest (16). The base will also be offered in an extendable 3-piece construction, the 3^rdpiece being an insert to cater to taller users.

Adjustable Foot Rest & Straps:

In one embodiment an injection-molded footrest (16) is used to provide a simulation of the footrest currently used in a real kayak. The footrest is textured to avoid slipping of the foot. The footrest is adjustable on the Base rails to accommodate different leg lengths (42). The footrest utilizes an adjustable and soft feel straps (38) to secure the feet in position (40).

Paddle Y-axis Resistance Setting:

In one embodiment a cam-locking system (24) is used to provide variable resistance to the y-axis movement of the paddle shaft. A section of pliable high molecular weight polyethylene (114) is used as a buffer that is squeezed onto the paddle providing greater resistance at set increments. (112) A resistance knob (90) is tightened by the user.

Paddle X-Axis Resistance Setting

In one embodiment a cam-locking system is used to provide variable resistance to the x-axis movement of the paddle shaft (122).

Paddle Catch

Omission of the invention of the double wedging catch as the v wedge male of the center of the horizontal shaft comes in to the v wedge female molding at the top of the vertical shaft. The action of the v wedge male entering the v wedge female and imparts resistance on the paddle and is configured to simulate the paddle blade resistance on entry into the water. AS understood, there are a pair of opposing v wedge female structures each configured to receive a single v wedge mail structure on each side of the rotation axis. (110)

Adjustable Height Vertical Shaft:

In one embodiment a system of adjustment is used to provide an adjustable high tech aluminum, carbon fiber, or other material, vertical shaft height dependent on the users torso length. One piece is attached to the Omniball (30) and has a spring button (94) while the other (32) has drilled holes (92) for the height adjustment. For hospital therapy and institutional use stainless steel made be used.

Adjustable Mini Paddle Blade:

In one embodiment an adjustable mini paddle blade (18) is used to simulate different pitches-control of paddles. Users are able to rotate the paddle blade to pre-set angle markings for more accurate simulation (36). This allows the user to deduce their own (Exact Feather). Feather defined as angle of blade control.

Rotation Ball (Omni Ball) and Adjustable Resistance and Adjustable Position:

In one embodiment a hand rotated locking system is used to provide variable resistance to the ball movement (28) in various tension settings (26). As the tension settings are increased (126) the top ball housing (128) squeezes down on the ball creating increased friction equal to the cube of the ball radius. The entire ball mechanism is adjustable depending on the users arm length and leg inside seam and torso length. Tension mechanics may be electrical, mechanical, hydraulic or some other means.

Adjustable Seat Length, Height and Angle Adjustable:

In one embodiment an adjustable, contoured seat is used (78). The seat has an adjustable front and back along the Base rails (54). The seat is also adjustable at an angle allowing the user to tilt the seat back up and down (52) to suit the users needs and forward and backwards away from the (Omni Ball) (56).

Foldable Configuration:

In one embodiment the horizontal shaft and vertical shaft are foldable (58) and removable (44) allowing the user to collapse the unit. Wheels attached to the base allow the user to easily roll the unit to a storage space.

Attachment Points for Multiple Unit Use:

In one embodiment a set of tongue and groove notches are molded into the front (56) and back (48) of the base allowing multiple units to be connected tandem in a linear fashion, simulating a multiple person kayak.

MyStroke Technology:

In one embodiment users are able to attach current existing MyStroke products to the paddle shaft to gain the advantages of digital performance gauging.
In one embodiment an attachment point for a smartphone/tablet computer is added to the footrest to provide a heads-up display of exercise data.
In yet another embodiment a built-in touchscreen LCD is added to the top of the footrest, integrating MyStroke technology directly into the unit.

Medical/Rehabilitation Use:

In one embodiment the system is used for medical rehabilitation of persons who have as example experienced a stroke or other injury associated motor-function disabilities. In this embodiment the unit has an additional stand to raise it off the floor and straps to keep the user secure. Additional high grade/easily cleaned materials are used as a substitute for many plastic parts. The seat/footrest format will change to accommodate the various medical/rehabilitation needs.
While the invention has been described in its preferred form or embodiment with some degree of particularity, it is understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication, and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention.
