Definitions

  • the present invention relates to an interface between two bodies, more particularly it relates to sporting goods handles or grips, tool handles, construction devices, railings or deck or floor surfaces which are to be grasped and held by a human user's hand or foot. Additionally, the invention relates to materials attached to a hand, glove or foot which interact with a similar material on another body.
  • Patents 3,368,811; 5,028,050; 5,335,916; and 5,451,046 illustrate the use of Velcro® fasteners interlocking a golf club and golf glove and interlocking a ball and a catching glove.
  • U.K. Patent 547946 shows the use of emery cloth or other abrasive frictional material on either a golf club or a golf glove. All of the above patents describe interfaces which either have only one of the articles or hand with the projections or provide both a lateral lock and a lock in the direction of the removal of the applied force i.e. generally perpendicular to the lateral directions of the lateral lock.
  • the gloves in the penultimate listed four patents must be sheared from the article and are not free to be generally disengaged easily from any direction from the article when the gripping force is released.
  • the present invention and product creates improved traction for a variety of human physical applications but at the same time permits easy disengagement.
  • the traction is meant to be improved particularly in the plane perpendicular to the main force applied.
  • this product will significantly prevent movement from side to side as well as in an inferior or superior direction if the tubular object were to be held horizontally.
  • disengagement easily occurs.
  • the traction will be overcome and the "grip" created by the product will be released.
  • This product is designed to be effective both for dry (land) and wet (aquatic) activities.
  • the invention consists of two identical or matching/integrated irregular surfaces not necessarily made of the same material.
  • One or both may be made either of rubber, plastic or other stiff yet pliable material while the other may be made of a nonflexible substance such as metal, rigid plastic or fiberglass.
  • These two surfaces When these two surfaces are placed together they will interlock or interdigitate. The interdigitation achieved is sufficient to create traction as described above, but releases easily.
  • These surfaces are designed for multiple applications and therefore will be of varying sizes, thicknesses, stiffness, material and design depending on the particular use.
  • One or both of the surfaces may have a self-sticking compound (i.e., tape) or may be attached by any adhesive product (i.e., glue) so that it can be applied to various already existing structures or devices.
  • a material with protrusions in a fixed spaced array is attached to the volar (gripping) surface of gloves and a material with matching protrusions in a fixed spaced array is attached to the gripping area of a baseball bat, tennis or other racquet, golf club, hockey stick, or the like.
  • This matching configuration of surfaces will achieve desired improved traction and grip as recited above.
  • the material with protrusions is formed or molded into the volar surface of surgical gloves as described above which interdigitates with the identical or matching configuration and sized protrusions which are generally made of a different material, such as the metal handle on surgical instruments. The material may be placed on the handle of hand tools, or on the plastic handle of a screwdriver.
  • one material may be attached to gloves and a matching material from a tape roll of material secured to such objects as construction devices such as a ladder, a railing along a stairway, a doorknob, or the like, for use of those needing a secure initial grip on the object with a quick parallel to the gripping force release.
  • a material with the protrusions is attached to the bottom of footwear either by a tape or glue or is an integral molded component and then an identical or matching surface of same or different material is mounted on or provided as an integral component of a surface to be walked on. This includes the placement of one material on the bottom of "deck shoes” and the matching material applied (or as an integral component of) to the deck of a sailboat or other vessel.
  • Still another application would be the material being applied to the bottom of boots and the matching material applied on the floor of a fish, meat or poultry processing plant to prevent employee slips.
  • An additional sporting goods application is the attachment of a first material with protrusions to the top or front portion of wetsuit booties (or built integral with the bootie) .
  • the complimentary material (either attached or as an integral unit) is attached to a corresponding undersurface of a footstrap on a sailboard, water ski or the like. This configuration will create traction and grip when the main force (from the foot) is applied upward and be released when the upward force is discontinued.
  • the first material may include roughened protrusions attached to the bottom of shoes and similar roughened protrusions extending from the second material attached to a skateboard. This enables a skateboard user to "jump" the skateboard into the air without losing contact due to the effect of gravity on the skateboard.
  • a frictional interface between a first body and a second body is described herein where an interface includes a first material attached to a first body, the first material having a first series of protrusions in a fixed spaced array, the series of the first protrusions extending from a surface of the first material.
  • a second material is attached to the second body, the second material also having a second series of protrusions in a fixed spaced array extending generally perpendicularly from a surface of the second material.
  • the first and second series of protrusions have non-adhesive surfaces and interdigitate with each other when the first body and second body are brought into abutting parallelism with each other by an applied force, such that lateral displacement of the interdigitated protrusions is substantially prevented, without substantially affecting generally parallel (to the protrusions) disengagement of the first series of protrusions and the second series of protrusions when the applied force is removed.
  • Fig. 1 is a perspective view of the invention showing the impending interdigitation of protrusions in both a glove material on a hand and on a sporting goods handle.
  • Fig. 2 is a schematic side view of a series of steps with a railing with the railing having a material including a series of protrusions for grasping by the gloved hand of Fig. 1.
  • Fig. 3 is a schematic side view of the invention showing the impending interdigitation of protrusions on a person's shoe sole and protrusions extending upwardly from a floor surface.
  • Fig. 4 is a perspective view of a second embodiment of a protrusions-containing glove.
  • Figs. 5-10 are perspective views of typical shapes and surfaces of the protrusions.
  • Fig. 11 is a perspective view of one of the materials of Fig. 1 showing the spacing of the protrusions on a portion of a material.
  • Fig. 12 is a perspective view of interdigitated portions of both materials.
  • Fig. 13 is a perspective view of the invention showing the impending interdigitation of protrusions on a water sports foot bootie and protrusions on the underside of a footstrap on a sailboard or the like.
  • Fig. 14 is an end view of a material tape roll containing the protrusions, with self-stick adhesive and peel-off paper backing.
  • Figs. 1 and 4 shows a first body in the form of a human hand 10 on which is placed a first material 11 formed and sized in the form of a glove to be worn and removably attached to the hand.
  • the glove may have full or partial fingers (Fig. 4) .
  • the material 11 may be a leather, rubber, fabric, e.g. nylon or cotton or plastic glove which contains a series of molded-in- place or stitched or adhesively attached pad-inserts 12 (Fig. 4) , particularly on a volar (palm) surface of the glove, each of which contain a series of columnar protrusions 14, generally extending perpendicularly from regions on the surface 15 of the glove.
  • the handle 18 may also be a tool handle such as a hammer handle, ax handle or a handle for a surgical tool.
  • a padding 9 such as synthetic foam tape or sheet e.g. EVA may be applied and bonded by adhesive under the material 16. In a horizontal orientation of the bat or tool relative movement side to side and in the inferior and superior directions is prevented by the grasping applied force on the materials and protrusions.
  • the glove may be a half- glove.
  • the volar portion may be a protrusions- containing adhesive tape which i ⁇ wound around the hand across the palm and back of the hand. This is especially useful when using a weight lifting bar also having protrusions-containing tape wound on spaced portions of the bar.
  • Fig. 2 shows a further application, where one or two gloves 15 of the type seen in Figs. 1 or 4 are used in conjunction with a railing 30 associated with a set of stairs 31 raising from a floor surface 32.
  • the railing 30 has vertical supports 33 and is covered or partially covered by a tape or sheet material 34 having a series of projections 35 extending therefrom.
  • a gloved user walks up or down the stairs the user's hand grasps the railing 30 and the respective protrusions on the glove and on the material affixed to the railing interdigitate, preventing slippage of the hand on the railing while permitting easy disengagement of the gloved hand from the railing as each step up or down the stairs is taken. This can be especially useful for infirm persons walking up or down stairs or a railed ramp.
  • the second material may also be applied to the railings or steps of a ladder.
  • Fig. 3 illustrates an application of the product to a walking or boating shoe 20 where the material 21 with a first series of protrusions 22 is applied to the sole of the shoe.
  • a floor surface 23 or boat deck or skateboard on which a second material 24 having a second series of protrusions 25 is affixed.
  • a pedestrian or boater places his or her so-equipped shoes down on the second material in a forward stepping motion (arrow 26) , with an applied force represented by the weight of the person, the first and second series of protrusions interdigitate with each other, as best shown in Fig. 12, to prevent forward and side sliding of the shoe with respect to the floor surface 23 and the fixed attached material 24.
  • the first series of projections are not impeded from releasing or disengaging in a generally parallel direction from between the second series of projections, as the applied force of the step is removed.
  • at least one of the materials may be a relatively stiff but pliable rubber or plastic such as polyurethane or a flexible epoxy.
  • the material attached to the floor surface may be an inflexible material or plastic such as an epoxy or polyethylene with raised integral protrusions as in a skateboard application as seen in Fig. 3.
  • Figs. 5-10 illustrate that the series of protrusions on both the first material and the second material may be smooth cylinders 40 (Fig. 5) , smooth cubic structures 41 (Fig. 6) , smooth octagonal cylinders 42 (Fig. 7) , a roughened cylinder 43 with projecting cylindrical nubs 44 (Fig. 8) , annular projections 46 on a curved top cylinder 45 (Fig. 9) , or a cubic structure 47 with annular trapezoidal projections 48 (Fig. 10) .
  • the protrusions may be rod- like with a height of from about 1 mm to about 2 cm with a diameter of about 1 mm to about 2 cm.
  • Other smooth or roughened surface areas on the protrusions may be provided, the roughened surfaces providing a predetermined small amount of friction during disengagement of the sets of protrusions as in a skateboard application as seen in Fig. 3.
  • Fig. 11 illustrates in blow-up that the diametrical space 28 between each of the series of protrusions 14 (Fig. 1) or series of protrusions 19 (Fig. 1) has a diameter A which is larger than the diameter B (or maximum cross-sectional dimension) of the protrusions so that the protrusions of one series will interdigitate and then easily disengage when an applied force is released.
  • Fig. 12 illustrates the actual engagement of one protrusion 19 from one material between four protrusions 14 of another material in a checkerboard grid.
  • the gaps 29 between the interdigitated protrusion are shown as relatively wide for clearer viewing purposes. Gaps of from about 2 mm to about 2 cm may typically be employed.

Abstract

L'invention porte sur une interface à friction entre un premier corps, la main (10) ou le pied d'une personne par exemple, et un second corps tel que le manche d'un article de sport ou d'un outil (18) ou un plancher (23) ou encore un dispositif structural comme la surface d'une rampe (30). On fixe une première matière (11) au premier corps, cette matière étant pourvue d'une série de protubérances (14) disposées en rangées à écartement fixe. Une seconde matière (16), qui est attachée au second corps (18), possède une série de protubérances similaires (19). Ces deux séries de protubérances, dont les surfaces ne sont pas adhésives, s'imbriquent les unes dans les autres lorsque les corps se rejoignent, selon un parallélisme donné, du fait de l'application d'une force de préhension telle que celle exercée par une main gantée ou d'une force d'appui telle que celle exercée par un pied chaussé durant la marche, ces forces s'exerçant sur la seconde matière. Si tout déplacement latéral des protubérances, une fois celles-ci imbriquées, est, de ce fait, sensiblement impossible, rien toutefois ne vient empêcher leur dégagement, d'une manière générale parallèle, lorsque les forces cessent de s'exercer.
