Claims21
A handgrip for an implement having a shank affixed to the handgrip, said handgrip, comprising:
- an elongated handgrip body formed with gripping surfaces engageable by fingers or a ball of a hand;
- and
- a layer of friction-enhancing particles bonded to said body extending over at least part of an area of each of said surfaces, said particles including granules with a particle size up to 100 .mu.m and synthetic resin or mineral fibers of a length up to 3 mm, the synthetic resin fibers being selected from the group which consists of polyamide, polypropylene and cellulose acetate.
The handgrip defined in 1 wherein said particles are provided on a carrier bonded to said body at said surfaces.
A method of making a handgrip for a tool, especially a screwdriver, which comprises forming a grip body connected to a shank, shaping gripping regions on said body for engagement by fingers or a ball of a hand of a user, and increasing friction at least in said regions by providing said regions with particles having a particle size of 1 mm to 5 .mu.m in mean diameter and bonding said particles on said body, said particles including granules with a particle size up to 100 .mu.m and synthetic resin or mineral fibers of a length up to 3 mm, the synthetic resin fibers being selected from the group which consists of polyamide, polypropylene and cellulose acetate.
