  • Patent number: 7464446
    Abstract: Method for obtaining an improved but easily adjustable and releasable frictional engagement between two contact surfaces. According to the method, both contact surfaces are provided with material layers (2, 4) which, when there is low contact pressure between the contact surfaces, ensure that these surfaces are able to move comparatively easily in relation to each other, but, when there is higher contact pressure, these material layers engage in each other and make relative movement between the contact surfaces impossible or substantially difficult. This can be achieved by means of both contact surfaces being flocked with a layer of short fibers (5), in particular synthetic fibers. The invention also relates to an arrangement for obtaining an improved frictional engagement between two contact surfaces and to objects provided with such contact surfaces.

When applied to a handle the grip wrap provides a firm and reversible grip, and is water-resistant. The shock and vibration dampening wrap includes an upper, denser grip elastomer layer overlaying a second, less dense base elastomer layer. These layers may be optionally conjoined by an elastomer adhesive, a built-up structure, or formed as a unitary structure without recourse to this elastomer adhesive. A grip wrap adhesive and primer are applied to an underside of the base elastomer to affix the grip wrap to the desired handle. An extrusion methodology for forming the grip elastomer layer further serves to create within the grip elastomer an open-celled structure having exceptional wicking characteristics.

The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.

    Abstract: A grip tape 11 for applying to a handle 94 generally comprises an elongate tape having a top portion 60 comprised of shock absorbing and compressible material, such as polyurethane, bonded to a shock absorbing bottom portion 90, such as of open-pored textile material, such as of felt. The top includes a central portion 62, a right densified portion 70 adjacent the right side 50 and a left densified portion 80 adjacent the left side 40. Preferably, the tops 75, 85 of densified portions 70, 80 are below the top 65 of the central portion 62 by at least 10% of the thickness of the tape. Preferably, bottom bevels 77, 87 underlie densified portions 70, 80. Tape 11 is spiral wrapped around handle 94 such that right side 50 overlies top 85 of left densified portion 80 of the previous turn, preferably such that top 75 of right densified portion 70 is disposed below top 65 of central portion 62 of the succeeding wrap.

  • Patent number: 5624116
    Abstract: A grip for a sports racquet, such as a tennis racquet, a squash racquet, a badminton racquet, or a racquetball racquet, comprises a thin layer of synthetic material and a porous backing material, e.g., felt. One or more longitudinal channels are formed in the thin synthetic layer to expose the backing material, thereby allowing moisture to pass directly to the backing material. The channel or series of channels run substantially coextensive with the grip, so that when the grip is wound onto a sports racquet handle, the channel or channels will be provided about the handle along its length. The exposed surface of the backing material may have a different color than the outer strip, to produce a pleasing decorative appearance. Also, in a preferred embodiment, a pair of parallel channels extend substantially the length of the strip, and a pair of parallel stitch lines, located between the channels, compress the outer surface of the strip to create a raised section.

  • Patent number: RE35673
    Abstract: A grip for a golf club shaft defined by a resilient strip that is spirally wrapped about the shaft of the golf club to vary the longitudinal profile of the shaft and grip as compared to the original longitudinal profile of the golf club shaft. Such grip may be readily applied by a golfer as a replacement for the original grip. The resilient strip may be spirally wrapped about a sleeve that has been positioned on the golf club shaft or, alternatively, about the bare golf club shaft.
