Abstract
Abstract of the Disclosure A wing to swim or row which includes a sleeve to attach to a member to be manipulated under water in generally fore to aft cycles of movement and an umbrella type collapsible canopy carried by the sleeve and movable in response to water forces caused by the manipulation between canopy open posi-tion and a canopy collapsed position to propel an object through water.
Description
~lO~73'7 Thi5 inyentiQn relates to a device for use by a swi~mer or oarsman for propulsion through water.
In the past it has been known to attach various type of devices to a body to be propelled through water in response to manipulation of the devices below the water surface. For example, United States Letters Patent No. 1,522,526 is of such a device. This invention is an improved device of the general class of attachments of which the above mentioned patent is typical.
This invention has as a general object the provision of a wing or umbrella canopy which is simple and inexpensive to manufacture and is well adapted for use as an attachment to the legs or arms of a swimmer or attach-ment to a rowing apparatus to be mounted to a boat; and the invention provides a sleeve to receive the member to which it is secured and an attach-ment means to maintain the sleeve in a predetermined position on the member;
and on the sleeve a collapsible umbrella type canopy or wing is secured and supported by pivotal struts and constrained upon movement of the device to movement between an open and a closed position in response to forces exerted upon it by manipulation of the device in water to create propulsion forces through water.
It is also an object of this invention to provide a device of the type described which is adapted by reason of its structure and configuration to be used as an attachment for the leg or arm of a swimmer and which includes a glove portion or sock portion to accommodate the hand or foot of the wearer and includes a sleeve of sufficient length to transmit substantial forces of propulsion to the arm or leg in use and which is configured so as not to scrape against the body of a swimmer.
It is a further object of this invention to provide a rowing apparatus for attachment to a boat which includes the umbrella type under 3'7 water propulsion improvement.
In accordance with these general objects and other objects which will be apparent from the following description, the invention in three pre-ferred embodiments uill now be described with reference to the accompanying drawings.
Figure 1 is a perspective view of a first preferred embodiment of the device adapted for attachment to the arm of a wearer;
Figure 2 is a bottom view of the device shown in Figure l;
Figure 3 is a perspective view of a second preferred embodiment adapted for attachment to the leg and foot of a wearer;
Figure 4 is a bottom view of the device of Figure 3; and Figure 5 is a perspective view of a rowing apparatus utilizing the wing.
First Preferred Embodiment:
The first preferred embodiment of Figures 1 and 2 is adapted to be used on a swimmer's left arm. A mirror image of the device may be worn on a swimmer's right arm and will not be described further. The device generally designated by the numeral 12 includes a sleeve 14 which is preferably of flexible plastic material or sturdy cloth, such as canvas. It includes means to secure it to the distal end of the arm of a swimmer, such as belts, not shown, or mating hooks 16 and 18 which are adapted to be tied together. A
glove segment 20 may be provided at the very end for passage of a hand.
Reinforcing rings 22, 24 and 26 may be provided. To the end of the sleeve a plurality of equispaced struts 28, 30, 32 and 34 are pivotally connected as at 36, 38, 40 and 42; and the struts extend a common distance. The struts are spanned by a canopy 44 of water impervious pliable material, such as plastic, uhich is in the shape of a segment of a circle as seen from an end view and is suitably secured to form what may be described as a collapsible 10~8~737 wing extending out~ardly from the sleeve. The canopy may be composed of a plurality o generall~ triangularly shaped circle segments, as shown, each secured in spanning relation between adjacent struts. Flexible string means of a common length 46, 48, 50 and 52 connect the struts to the sleeve by suitable means, such as staples as at 54, 56, 58 and 60 and 62, 64, 66 and 68 on the sleeve preferably at the reinforced zone 24. In the preferred embodi-ment one way check valve means such as 70, 72, 74 and 76 may be provided and comprise openings 78, 80, 82 and 84 at predetermined spaced locations of the wing canopy which on the inside surface are covered by patches 86, 88, 90 and 92 which have margins that overlay the margins of the canopy about their respective associated openings. The margins are secured to the canopy at spaced points so that when the wing is pulled toward the elbow through water, the margins will closely overlay one another and not permit water to flow through the openings, but will open when the wing is pushed forwardly through water. Also, when the wing is pushed forwardly the wing will collapse as the struts pivotally approach alignment with the sleeve centerline; and when the wing has completed a forward stroke of a swimming cycle and pulled rearwardly, the canopy by pivotal action of the struts will open in response to the forces exerted by the water to a fully opened position shown in Figure 1 with the string means being taut and restraining further movement until rearward movement has been completed. A flexible end flap 95 to trap water may be included on the wing.
Second Preferred Embodiment:
The second preferred embodiment of Figures 2 and 3 is adapted to be used on a swimmer's foot. It differs from the previously described embodiment in that a partial flexible sock 200 is suitably secured at the distal end 202, which preferably is cut away at the heel zone 204 and toe zone 206. In operation this embodiment is secured to the foot and used similarly to the description aforesaid. Rather than repeat the numbers and description in all detail with respect to this embodiment, similar parts of the wing correspond-ing to the embodiment of Figures 1 and 2 are designated by a series of corresponding numbers ~ith a prime designation.
Third Preferred Embodiment:
The third preferred embodiment is shown in Figure 5; and illustrates the use of the wing on a rowing apparatus. The common wing parts are desig-nated by numbers corresponding to those used in the description of the first and second embodiments with the exception that double prime designations are utilized to shorten this specification. It should be noted that the sleeve is cylindrical, rather than of somewhat truncated cone shaped, to accommodate the elongate mating fore to aft alligned shaft 302 to which it is secured by suitable means such as the headed sets of screws 304, 306 and 308, 310.
Further it should be noted that the canopy is circular when expanded as seen in an end elevation view instead of a segment of a circle as in the case of the embodiments of Figures 1 and 2 and Figures 3 and 4 so as not to scrape against a swimmer's body.
The apparatus on which the wings are mounted will now be described.
A bracket means 312 is secured to the gunnel 314 of a boat 316 for example in clamping engagement between two blocks 318 and 320. A vertically oriented pivot pin 322 extends upwardly and is pivotally connected to the handle stem 324 of an oar type member 326 with a handle 328. An elongate vertical force transmitting means composed of elements 330, 332 and 334 extends upwardly from the shaft 302. Preferably each of these elements are bifurcated at their respective lower ends 336, 338 and 340 and pivotally connected in a generally clevis or yoke arrangement to the shaft by pivot pins 342, 344 and 346; and, at their respective upper ends, the same are pivotally connected to a bridging member 348 by pivot pins 350, 352 and 354, the bridging member being 10~i8737 ixed by ~uitable means to the clamp hlock 320.
~ n operation the oar is manipulated in a fore and aft series of cycles to transmit fore and aft movement of the shaft 320 and carried wings ~hich collapse and expand beneath the water to propel a boat on which it is installed through the water.
In each of the embodiments the canopy when collapsed may be secured in close collapsed relation about the shaft arm or leg, for example, as shown in Figures 1 and 2 by use of the draw string 99.
