The present invention relates to hand-held paddle apparatuses. Specifically, the hand-held paddle apparatuses are useful for moving a body through a fluid, such as water, and providing use of hands and fingers for other functions. Moreover, the hand-held paddle apparatuses are hinged to reduce the surface area interacting with the fluid when the paddle apparatuses move in one direction, and to open to increase the surface area interacting with the fluid in an opposite direction.
It is, of course, generally known to utilize paddles and flippers to enable a user to move through a fluid, such as, for example, an amount of water. Indeed, water flippers, otherwise known as swim fins, are finlike accessories that are typically worn on the foot or leg and made from rubber, plastic or combinations of these materials, to aid movement through the water in water sports activities such as swimming, bodyboarding, bodysurfing, knee boarding, river boarding, underwater hockey, underwater rugby and various other types of underwater diving.
Swim fins generally help the wearer to move through water more efficiently, as human feet are typically too small and inappropriately shaped to provide much thrust, especially when the wearer is carrying equipment that increases hydrodynamic drag. Very long fins and monofins used by freedivers as a means of underwater propulsion do not require high frequency leg movement. This improves efficiency and helps to minimize oxygen consumption. Short, stiff-bladed fins are effective for short bursts of acceleration and maneuvering, and are useful for bodysurfing.
Swim fins were proposed by Leonardo Da Vinci and Benjamin Franklin. It was not until 1914 that the first practical demonstration of a pair of swim fins was made by inventor Louis de Corlieu, a captain in the French Navy. Variations of the first swim fins developed over the years, and today swim fins come in many types of shapes and sizes, and are made from various materials, depending on their application.
Swim fins, as noted above, are generally worn on the legs and/or feet. As such, they are used to propel a wearer in one direction by kicking against the fluid in the opposite direction. Wearers use scissor kicks, frog kicks, or dolphin kicks for propulsion. Typically, swim fins are not required to move against the direction of desired motion.
When a person is swimming through water, his hands and arms typically move differently than the legs and feet. Legs and feet generally move back-and-forth or in a kicking motion, and generally do not have to move against the movement of the fluid. However, a swimmer must rotate their arms in order to get the hands into a position to aid in pushing the body through the water. This means that the hands and arms must typically move in the direction of movement, and against the fluid. A swimmer tends to minimize the surface area of his or her hands when moving them in the direction of movement to minimize the interaction of the surface area of the hands against the fluid.
Heretofore, swim fins are not generally suitable for use on a wearer's hands because swim fins typically have a surface area that cannot be easily or readily changed when swim fins are moving against the fluid in which the wearer is moving. Thus, swim fins have not heretofore been adapted for hands to be used in the same manner as they are used on legs and/or feet.
Swimming gloves are known that aid a wearer in moving through a fluid such as water. Swim gloves typically have individual fingers with webbing therebetween. When a wearer moves his or her hand against the fluid, the wearer can keep the fingers close together to minimize the surface area. When the wearer moves his or her hand with the fluid to provide further propulsion through the fluid, the user can open his or her fingers to increase the interaction of the fluid on the webbing. However, while swim gloves can provide some propulsion, the webbing provided does not typically provide a large amount of surface area to interact with the fluid through which a wearer is moving, so the amount of propulsion is fairly minimal. In addition, in some cases, in order to increase the surface area, the webbing and other features on the gloves are increased, or made stiffer, which decreases the wearer's ability to use his or her fingers and hands for other functions without removing the gloves.
A need, therefore, exists for hand-held paddle apparatuses to aid a wearer in moving his or her body through a fluid, such as water. Moreover, a need exists for hand-held paddle apparatuses that may be worn on a user's hand and may be easily removed when desired.
Further, a need exists for hand-held paddle apparatuses that may be useful to move a wearer through a fluid, but does not impede a wearer from moving through the fluid when the hands are moved against the fluid. Still further, a need exists for hand-held paddle apparatuses that provide increased surface area when the paddle apparatuses move in the direction of the fluid movement, and provide decreased surface area when the paddle apparatuses move against the direction of the fluid movement, thereby maximizing propulsion against the fluid, and minimizing drag with the fluid.
In addition, a need exists for hand-held paddle apparatuses that may provide for unrestricted movement and use of the hands and, more specifically, the fingers of the wearer's hands when being worn. Specifically, a need exists for hand-held paddle apparatuses that allow a user to use his or her hands for other functions, such as holding other items, when wearing the paddle apparatuses.

Additional features and advantages of the present invention are described in, and will be apparent from, the detailed description of the presently preferred embodiments and from the drawings.
The drawing figures depict one or more implementations in accord with the present concepts, by way of example only, not by way of limitations. In the figures, like reference numerals refer to the same or similar elements.
The present invention relates to hand-held paddle apparatuses. Specifically, the hand-held paddle apparatuses are useful for moving a body through a fluid, such as water, and providing use of hands and fingers for other functions. Moreover, the hand-held paddle apparatuses are hinged to reduce the surface area interacting with the fluid when the paddle apparatuses move in one direction, and to open to increase the surface area interacting with the fluid in an opposite direction.
Now referring to the figures, wherein like numerals refer to like parts,
The hand-held paddle apparatus 10 preferably comprises a palmar portion 12 comprising a strip of material that is positioned, as illustrated in
Adjacent the palmar portion 12 of the paddle apparatus 10 may be a hand cover 32 having an aperture therein that may allow a user to dispose a portion of his or her hand 31 and/or his or her fingers therethrough, as illustrated in
Extending from the palmar portion 12 may be a wide paddle portion 26 that may catch the water and aid a user in propelling him or herself through the water. The paddle portion 26 may be shaped to catch water to allow a user to propel him or herself through the water. The paddle portion 26 may be any shape for that purpose, and may be uniquely shaped to mimic an animal's parts, such as a shark fin, a frog's foot, or a duck's foot.
The paddle portion 26 may comprise one or more reinforcement spines 28 that may extend from hand cover 32 to or near the terminal end of the paddle portion 26 on a top thereof or integrally formed within the paddle portion 26. The one or more reinforcement spines 28 may provide reinforcement of the paddle portion 26, especially when the paddle portion 26 moves against a fluid, such as when the paddle apparatus 10 is worn on a user's hand to propel the user through a fluid, such as water.
The one or more reinforcement spines 28 may further have one or more hinge elements 30 disposed therein to allow the paddle portion to fold in strategic locations. For example, as illustrated in
The hand-held paddle apparatus 10 may be made from any material useful for its purpose, including plastic, metal, wood, composite materials, other like materials, or any combination thereof. Preferably, the hand-held paddle apparatus 10 may be made from an elastomeric material that may be relatively soft, yet sturdy and resilient. Further, the paddle portion 26 may be made from a flexible material that easily folds, especially as the hinges 30 allow the one or more reinforcement spines to fold at the hinges 30, thereby allowing the entirety of the paddle portion 26 to fold therewith.
The webbing 34 may extend from the finger sleeves 25 and connect on an underside of the paddle portion 26 longitudinally on the paddle portion 26 toward the terminal end thereof. The webbing 34 may thereby link the finger sleeves 25 to the paddle portion, such that when the user flexes or bends his or her hand 31 and fingers, the paddle portion 26 may be pulled downwardly toward the palmar portion of the user's hand, thereby bending the paddle portion 26 at the hinges 30 of the reinforcement spines 28.
It should be noted that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. Further, references throughout the specification to “the invention” are nonlimiting, and it should be noted that claim limitations presented herein are not meant to describe the invention as a whole. Moreover, the invention illustratively disclosed herein suitably may be practiced in the absence of any element that is not specifically disclosed herein.
