Abstract
A collapsible blade equipped paddle device enabling an underwater return stroke includes a shaft, which has a blade engaged to a first end thereof. The blade comprises a frame having a panel engaged thereto and extending therebetween. The frame is selectively collapsible so that the blade assumes an open cupped configuration when a forward stroke is applied to the shaft and a collapsed configuration when an underwater return stroke is applied to the shaft. The blade provides thrust to a marine vessel during the forward stroke and minimal resistance during the underwater return stroke.
Claims
1. A collapsible blade equipped paddle device comprising: a shaft; and a blade engaged to a first end of the shaft, the blade comprising a frame having a panel engaged thereto and extending therebetween, the frame being selectively collapsible, such that the blade assumes an open cupped configuration when a forward stroke is applied to the shaft, and a collapsed configuration when an underwater return stroke is applied to the shaft, wherein the blade is configured for providing thrust to a marine vessel during the forward stroke and minimal resistance during the underwater return stroke; and wherein the frame comprises a first rod engaged by a first terminus to the first end the shaft and extending therefrom, the first rod being angled or curved, and a pair of second rods, each second rod being angled or curved, each second rod being pivotally engaged to and extending between the first terminus and a second terminus of the first rod, such that the pair of second rods defines a field, the panel being engaged to the pair of second rods and extending over the field.
2. The collapsible blade equipped paddle device of claim 1, wherein the shaft is cylindrical.
3. The collapsible blade equipped paddle device of claim 1, wherein the panel comprises rubber, silicone, or elastomer.
4. (canceled)
5. The collapsible blade equipped paddle device of claim 1, wherein the first rod extends transversely from the shaft.
6. The collapsible blade equipped paddle device of claim 1, further including the frame comprising a pair of crossbeams, each crossbeam being pivotally engaged to and extending between a respective second rod and the first rod.
7. The collapsible blade equipped paddle device of claim 1, further including: the frame comprising a pair of crossbeams, each crossbeam being pivotally engaged to and extending between a respective second rod and the first rod; and the first rod and the second rods being angled, such that the frame defines four sections of the panel, each section being triangularly shaped, such that the blade is substantially kite shaped in the open cupped configuration.
8. The collapsible blade equipped paddle device of claim 1, further including a grip engaged to the shaft proximate to a second end thereof.
9. A collapsible blade equipped paddle device comprising: a shaft, the shaft being cylindrical; a blade engaged to a first end of the shaft, the blade comprising a frame having a panel engaged thereto and extending therebetween, the frame being selectively collapsible, such that the blade assumes an open cupped configuration when a forward stroke is applied to the shaft, and a collapsed configuration when an underwater return stroke is applied to the shaft, wherein the blade is configured for providing thrust to a marine vessel during the forward stroke and minimal resistance during the underwater return stroke, the panel comprising rubber, silicone, or elastomer the frame comprising: a first rod engaged by a first terminus to the first end the shaft and extending therefrom, the first rod being angled the first rod extending transversely from the shaft, a pair of second rods, each second rod being angled, each second rod being pivotally engaged to and extending between the first terminus and a second terminus of the first rod, such that the pair of second rods defines a field, the panel being engaged to the pair of second rods and extending over the field, and a pair of crossbeams, each crossbeam being pivotally engaged to and extending between a respective second rod and the first rod, such that the frame defines four sections of the panel, each section being triangularly shaped, such that the blade is substantially kite shaped in the open cupped configuration; and a grip engaged to the shaft proximate to a second end thereof.
Description
BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWING(S)
[0011] The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
[0012]

DETAILED DESCRIPTION OF THE INVENTION
[0017] With reference now to the drawings, and in particular to
[0018] As best illustrated in
[0019] The blade 14 comprises a frame 22 having a panel 24 engaged thereto and extending therebetween. The panel 24 comprises rubber, silicone, or elastomer. The frame 22 is selectively collapsible so that the blade 14 assumes an open cupped configuration, as shown in
[0020] The frame 22 comprises a first rod 26, a pair of second rods 28, and a pair of crossbeams 30. The first rod 26 is engaged by a first terminus 32 to the first end 16 the shaft 12 and extends therefrom. The first rod 26 is angled or curved. The first rod 26 may extend transversely from the shaft 12, as shown in
[0021] Each second rod 28 is angled or curved and is pivotally engaged to and extends between the first terminus 32 and a second terminus 34 of the first rod 26. As shown in
[0022] Each crossbeam 30 is pivotally engaged to and extends between a respective second rod 28 and the first rod 26. With the first rod 26 and the second rods 28 being angled, as shown in
[0023] In use, the device 10 can be employed by a user to propel a rowboat, canoe, kayak, or the like. During a forward stroke, the blade 14 assumes the open cupped configuration and provides thrust to the marine vessel. The device 10 enables an underwater return stroke having minimal resistance due to the frame 22 assuming the collapsed configuration. The device 10 provides an easier to perform alternative to what is called an Indian Stroke, wherein a standard paddle is rotated 90 degrees at the end of a forward stroke and prior to performing an underwater return stroke.
[0024] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
[0025] Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be only one of the elements.
