Definitions

  • Water sports have grown in popularity and variety in the past decade. In particular, some water sports, such as surfing, specifically require only paddling with the hands. Other well known water sports, such as swimming, body surfing, snorkeling and scuba diving, require both the hands and feet to generate motion. All of these activities would be enhanced by adding webbed hands.
  • the prior art teaches a variety of swimming aids which provide webbed areas between the thumb and index finger and between the rest of the fingers of a swimmer's hand.
  • the objectives of the prior art are either accomplished through a number of over-inclusive features which result in overly complex and expensive fabrication costs or overly simplistic elements which do not survive the rigors of active swimming.
  • Rigid paddles have also been used in certain water sports such a kayaking. However, such rigid paddles were simpfy - strapped to the wearer's hands, and were effectively only oars without handles. These paddles caused fatigue and discomfort and do not have the flexibility required for the other discussed activities.
  • Providing webbing between the thumb and fingers of a swimmer's hand provides improved swimming abilities by increasing the amount of fluid displaced by each stroke of the swimmer's hand.
  • the additional resistance afforded by such webbing is advantageous in the training of swimmers in that it improves the swimmer's control, thereby buoying the swimmer's confidence in his abilities and builds muscle tone due to the additional effort required to move the arm through the water.
  • the present invention provides an inexpensive, portable webbed swimming aid to be worn on the hands while swimming or participating in other water sports.
  • This swimming aid performs the functions of a paddle while providing the comfort and flexibility of gloves. Grasping objects, scratching an -itch, and other feats of manual dexterity are still possible as the fingertips are exposed.
  • the swimming aid provides improved fluid displacement of the wearer's hands without impeding other activities which require use of the hands.
  • the webbed swimming aid of the invention is constructed of two superimposed planar sheets which are easily sized to a variety of sizes- One sheet, the back side of the swimming aid, is cut from an elastic, porous, mesh material which customizes the aid and acts as a glove to snugly fit the wearer's hand.
  • the second sheet, the palm portion of the swimming aid is made of somewhat rigid yet flexible, water resistant or water impermeable material.
  • the two sheets are cut into fan shaped pieces which generally conform to the shape of an outspread hand.
  • stitching or other well known means are used to join the outermost side edges of the swimming aid- Open-ended finger stalls spaced apart by closed webbed areas are formed by stitching or sealing areas along the upper edge of the superimposed sheets.
  • the stitching or sealing means form generally ovoid triangular areas to define the finger stalls.
  • Other stitching patterns such as single lines directed from the fingertip edge towards the wrist portion could also be used to provide exira wide finger stalls that utilize the overall fan shape of the sheets as a singular webbed area.
  • the two sheets may be identical in outer dimensions when first cut, with wear, the elastic mesh material may become permanently stretched to be somewhat larger than the second sheet of water resistant or water impermeable material. Such permanent deformation of the first sheet of material is desirable, as it permits the two-dimensional structure of the swimming aid to better adapt to the three-dimensional size variations in human hands.
  • the swimming aid of the invention is flexible enough to allow the swimmer, after putting on the first of a pair of the swimming aids, to put on the second swimming aid without assistance.
  • a wrist strap may be provided along the wrist portion of the swimming aid to further secure the device to the swimmer's hands. Complicated closures would not be advisable since more delicate movements are awkward. Elasticized straps, snaps or various hook and loop fasteners have all been found to be satisfactory.
  • the present invention also permits freedom of movement of the swimmer's exposed fingertips allowing the swimmer to grasp other watersports equipment, such as cameras, surfboards, etc. Exposure of the fingertips also provides psychological benefits to the wearer.
  • the disclosed invention addresses all of the concerns of the prior art, while reducing the expense of construction of the devices. Costs are minimized since no molding or specialized parts are required.
  • the major components may be cut from two different sheet materials using a single pattern. The patterns are easily designed to fit from infant to adult sizes. The components are joined by a simple stitching or heat-sealing device. The resulting product is inexpensive, highly portable (i.e., rolling up to fit in a pocket), adaptable to variations in hand sizes, and very effective.
  • the swimming aid of the present invention may easily be stowed aboard windsurfing boards and water vessels for emergency purposes.
  • Fig. 1 illustrates the simplicity of the construction from the top plan view.
  • the structural properties of the sheet materials from which the swimming aids are fabricated are of particular importance.
  • the swimming aid is primarily constructed from two superimposed, fan-shaped planar sheets 2 and 4, which conform generally to the shape of an outspread hand.
  • the lower sheet 2 is constructed of a flexible, relatively stiff, water resistant or water impermeable material. The stiffness is required to withstand the force of the fluids exerted on the webbed areas during swimming. Also, the material must not be so supple as to accordion-foid downwardly along the swimmer's fingers so as to reduce the surface area of the webbing.
  • the upper sheet 4 holds the lower sheet against the wearer's hand.
  • the two sheets are joined along the side edges and have open-ended finger stalls formed by stitched patterns spaced along the sheets.
  • the normally upper sheet 4 primarily acts as the glove portion of the swimming aid to secure the webbing to the swimmer's hand.
  • This upper sheet material which is elastic and porous, should permit water to pass through it fairly easily. It should not be very absorbent, since absorbed water would cause the webbed aid to become unnecessarily heavy and might cause the shape of the sheet to deform, causing the fit to be less snug.
  • the elastic mesh material forms the glove portion of the swimming aid that adapts the aid to the size of the particular wearer.
  • the patterns for cutting the sheet material may be approximately sized to fit a certain range of hand sizes, but it is the elastic quality of this sheet of material which fine tunes the fit. The fit must be snug to prevent slippage along the hand during use.
  • Fig. 2 illustrates the position of the upper sheet 4
  • Fig. 3 illustrates the lower sheet 2 as seen from below the swimmer's hand.
  • the normally lower sheet 2 of material must have sufficient rigidity and stiffness to provide webbed surfaces which are firm enough to displace water and withstand the force of the swimmer's stroke. It is to be understood that the webbed surface area must be maximized in order to displace the most water while the aid is being used as a paddle. If the lower sheet of material was so resilient as to collapse or crumple along the finger areas, the effective surface area of the webbing would be reduced, reducing the effectiveness of the swimming aid. However, this lower sheet of material must be flexible enough to allow the swimmer to comfortably cup the hand during the swim stroke, thereby further increasing the amount of fluid displaced by each stroke.
  • the lower sheet of material must also permit a certain degree of freedom of movement to allow the swimmer to put on the swimming aid without assistance and grasp other objects while wearing the aid.
  • Polyester weave fabric with vinyl coating, heavy duty ballistics cloth with vinyl or urethane coating, Tarp-Lite 3214 or Tarp-Lite 3222 available from the Shelter-Lite Co., and Cordura@ nylon with a waterproof coating have all proven to be satisfactory as the lower sheet material for the purposes of this invention.
  • Fig. 4 is a sectional view taken along the lines 4-4 in Fig. 2.
  • the fingertip of each finger and the thumb are left exposed while the swimmer wears the swimming aid.
  • the open ended structure of the finger stalls also enhances the universal sizing of the patterns for the aid. Variations in the lengths of fingers in wearers are easily tolerated by this open configuration.
  • This feature also permits the swimmer to easily grasp and manipulate objects such as other water sports accessories, for example cameras, surfboards, boogie boards and the like. For those persons- wearing the swimming aid while learning to swim, having the sensitive fingertips exposed enhances the swimmer's sense of security by not inducing a claustrophobic sense of being enclosed by equipment.
  • the elastic mesh material 4 is less likely to slip along the skin of the hand' once the material has become wet.
  • This quality of the material permits the wearer to adjust the position of the swimming aid towards or away from the wrist to some extent depending on the wearer's needs at the particular moment. For instance, while swimming or scuba diving, it is best to wear the aid as far away from the wrist as is comfortable to maximize the additional force generated by the paddle-effect of the outspread webbed hand. While manipulating objects such as underwater cameras or adjusting oxygen tanks, the wearer may, instead of completely removing the aid, pull the aid towards the wrist to expose more of the fingertips.
  • both sheets are cut from substantially identical fan shaped patterns.
  • the outline of the. fan shape conforms generally to the shape of the fully outspread hand.
  • the sheets must be produced in left hand and right hand versions. A range of sizes are easily provided to suit the size of the individual swimmer.
  • the lower sheet 2 differs in shape from the upper section 4 in that it has a wrist portion 6 to which a wrist band 8 is secured.
  • the wrist band may be provided with easily adjusted fastening means such as Velcro@ hook and loop fasteners.
  • Figure 1 illustrates a wrist strap 8 formed of lengths of hook and loop fastener tape.
  • the strap 8 is threaded through a loop 9, and is of sufficient length that a hand may be inserted even when the end 11 is threaded through loop 9.
  • the wearer need only pull the already threaded end 11 and fold the strap over to engage the hooks and loops. This can be done easily when already wearing an aid on the other hand.
  • a flotation device such as a small section of closed-pore foam may also be incorporated into the wrist portion of the lower sheet 2 so that the swimming aid will float if inadvertently dropped into the water.
  • the upper sheet 4 has a curved wrist edge 10 at the wrist edge of the sheet to permit greater freedom of movement and to allow easy insertion of the hand into the aid.
  • the swimming aid may easily be customized to suit a variety of applications. Different versions of the swimming aid may be constructed according to the specific intended application. For instance, surfers may only need to use the swimming aid when paddling. Surfers would find a version of the swimming aid which is softer, such as one constructed with a second sheet of Cordura@ to be most effective. Simpler stitching patterns (such as single lines) might be sufficient to define the finger stalls for aids intended to be worn only for paddling purposes. A softer glove would permit the surfer to easily grasp the board, be comfortable to wear, and yet provide improved paddling ability. Serious swimmers might require varying degrees of stiffness from the swimming aid, depending on the particular swim stroke for which the swimmer is training. For those situations in which it is occasionally desirable to have the fingers together, the webbing must be pliable enough to permit the fingers to be moved together axially.
  • the webbed area may be reinforced by placing triangular shaped stiffeners 5 in the regions between the finger stalls prior to stitching. 'Such stiffeners would be suitable for enhancing the rigidity of the webbing area where softer material for the bottom sheet of the swimming aid is desirable.
  • Figure 1 also illustrates such another embodiment of the invention which would include stiffener members 5 sewn within the region defined by the triangular stitching or stitching patterns 16. The stiffener member is cut of a material of the desired rigidity in a generally triangular shape to fit between the upper sheet 2 and lower sheet 4 in the webbing areas separating the various finger stalls.
  • Another embodiment (not illustrated) of the invention provides for a single arcuate stiffening member to be attached to the fingertip edge of the bottom second sheet of material. The side seams and triangular patterns are then joined in the usual manner.
  • This arcuate stiffening member may be of any stiff, water resistant material, and would counteract any tendency of the webbed regions to collapse downwardly along the fingers.
  • a single stiffening member would permit a softer material to be used as the bottom sheet, without greatly increasing the labor required to construct the aids.
  • the upper sheet 4 and lower sheet 2 after all raw edges have been finished to prevent fraying of the material as necessary, are sandwiched according to whether they are to be left handed or right handed.
  • the superimposed sheets are sealed along the thumb side seam 12 and the outer side seam 14 by stitching or other joining means such as heat-sealing.
  • One method that has been found to facilitate the manufacture of the swimming aid includes gluing the two sheets of material together with a water-soluble glue, rubber cement, or other temporary adhesive, prior to cutting the aids from patterns. This gluing step assures that the layers do not slip and permits the simultaneous cutting of both sheets. The pieces are then finished to the extent possible, depending on the specific features of the embodiment, before the pieces are soaked in water (or other appropriate measures are taken) to remove the adhesive.
  • the wrist band 8 and a flotation device, if any, is then secured to the wrist section 6 by similar well known means. If a single arcuate stiffener is to be added, it is separately fastened to the bottom sheet of material. The finger stalls are then formed by a series of triangular stitching or fusing patterns 16.
  • each triangular pattern 16 may be first stitched to form a pocket for the stiffener member 20.
  • the stiffener member 20 may then be inserted, and the upper edge of the pattern 16 stitched or sealed at 18 of the webbed areas to enhance the rigidity of the webbed areas and the swimming aid as a whole. It is to be understood that a variety of stitching patterns could be used to accomplish the requirements for which the particular aid is intended.
  • the overall shape of the planar upper sheet 4 and lower sheet 2 must be approximately sized to accommodate the three-dimensional structure of the wearer's hands.
  • the placement of the stitching triangles 16 must account for sufficient ease in the size of the finger stalls to accommodate the anticipated size range of fingers.
