No. 5,960,578; incorporated in its entirety herein by reference). These inorganic antimicrobial agents cause less skin irritation and offer much improved longevity, when compared with typical volatile organic agents. In addition, silver-based inorganic antimicrobial agents rarely cause metal allergies when compared with inorganic germicidal agents containing metals other than silver.
  • Some silver-based inorganic antimicrobial agents are commercially available, such as for example, BACTEKIRANI (Kanebo Co.), which is a complex of silver and zeolite, and NOVALON, (Toa Gosei Co.), which is a complex of silver and zirconium.

  • the purpose of the layer of polyurethane 16 is primarily to provide a cushioning effect for the handle grip, which protects the user against impact-related shock and/or shifts in load-bearing. Such cushioning effect is enhanced by compression of the vertically aligned pores 22 in the polyurethane layer. It has been found that such compression greatly inhibits the shock applied by a club or racquet to the user's arm and hand created when the ball hits the club or racquet.
  • the polyurethane layer 16 also provides tackiness so as to inhibit the user's hand from slippage.

  • the polyurethane and felt layers may be formed with vertically extending perforations as illustrated in FIGS. 6 and 7.
  • the perforations are adapted to improve the resistance to slippage by enhancing the absorption rate of perspiration from a user's hand.
  • Such pores or perforations have also been found to improve the cushioning effect of the grip by providing a controlled restriction of air escaping from within the open pores of the felt layer when the grip is grasped.
  • the invention is not limited to clubs and racquets designed to impact a ball.
  • the antimicrobial grip in accordance with preferred embodiments of the present invention can be applied to any handle or shaft in which protection is desired from inter alia: (1) the detrimental and health-related effects of microbial growth; (2) impact-related shock; (3) changes in load-bearing; and (4) slippage.
  • Detrimental effects of microbial growth on grip performance and useful life include without limitation, discoloration, odor, slimy and/or slippery tactile effect, deterioration of grip materials, de-lamination of the elastomer and textile layers, reduced adhesion to the handle shaft, etc.

  • Staph is bacteria commonly found on human skin. Sometimes it does not cause any problems; sometimes it causes minor infections, such as pimples or boils. The skin infections often begin with an injury to the skin where the Staph enters the skin weakened by the injury and develops into an infection. Symptoms of a Staph infection include redness, warmth, and swelling, tenderness of the skin, and boils or blisters. Staph can rub off the skin of an infected person onto the skin of another person during prolonged skin to skin contact between them, or it can come off the infected skin of a person onto commonly shared objects or surfaces, and get into the skin of the person who uses it next. . . Examples of objects that are commonly shared are . . . athletic equipment used in a gym.”

In contrast, the level of bacteria surviving on the untreated, control grip was essentially the same as the starting (0 hour) inoculum. Clearly, the incorporation of 2% by weight of the inorganic antimicrobial agent within the outer polyurethane layer of the grip material resulted in a handle grip which effectively eliminates bacteria from the grip surface.

  • silver provides antimicrobial actions via three distinct mechanisms of action: (1) catalytic oxidation, (2) reaction with cell membranes, and (3) binding to microbial DNA to prevent transcription. More particularly, atomic(nascent) oxygen absorbed onto the surface of silver ions will readily react with the sulfhydryl (—S—H) groups surrounding the surface of bacteria or viruses to remove the hydrogen atoms (as water), causing the sulfur atoms to form an R—S—S—R bond; blocking respiration and causing the bacteria to expire. There is evidence that silver ions attach to membrane surface radicals of bacteria, impairing cell respiration and blocking its energy transfer system.
  • —S—H sulfhydryl
  • silver was shown to be effective in treating ear infections, yeast infection ( Candida ), viral infection (common cold), E. coli infection, intestinal infection, sinus infection, HIV infection, Lyme disease, Herpes (HSV-2) viral infection, Anthrax infection, and food poisoning.
