Gripping sleeve device for precision instruments

摘要

The invention provides an ergonomic, gripping sleeve device for precision instruments, comprising a tubular product open at opposite ends thereof and attachable as a sleeve close to a proximal end of said precision instrument having a working tip at its proximal end, said sleeve device being designed to facilitate the positioning of the user's hand grip, said sleeve device comprising a longitudinally extended tubular body substantially hollow and oval in cross-section and being provided on its outer surface with four, substantially concave indentations, a first concave indentation being provided along a top surface of said sleeve device, second and third indentations being provided along lateral surfaces, and a fourth indentation being provided along the bottom surface of said sleeve device, characterized in that the surface of the top of said sleeve device is contoured such that extending from its distal end toward its proximal end and approaching said proximal end there is provided said concave indentation which extends and merges into an elevated surface support which tapers angularly towards said proximal end of said sleeve device, so as to allow for positioning of said user's index finger sufficiently close to said proximal end of said sleeve device and wherein said sleeve device comprises a plurality of sequential ovals of varying width and shape, and wherein said indentations are positioned relative to each other to provide a contiguous interface therebetween and a contiguous interface relative to the user's thumb, index finger and middle finger to facilitate controlled rolling between the user's fingers.

1. An ergonomic, gripping sleeve device for precision instruments, comprising a tubular product open at opposite ends thereof and attachable as a sleeve close to a proximal end of said precision instrument having a working tip at its proximal end, said gripping sleeve device being designed to facilitate the positioning of the user's hand grip, said gripping sleeve device comprising a longitudinally extended tubular body substantially hollow and oval in cross-section and being provided on its outer surface with four, substantially concave indentations that include a first concave indentation provided along a top surface of said gripping sleeve device, which first concave indentation extends and merges into an elevated ridge-like surface support that is proximally positioned relative to the first concave indentation, second and third indentations being provided along lateral surfaces, and a fourth indentation being provided along the bottom surface of said gripping sleeve device, and wherein the substantially hollow and oval in cross-section tubular body comprises, along a longitudinal length of said tubular body, a plurality of sequential oval cross-sections of varying width and shape and each with an oval major diameter axis extending in a top to bottom direction, and wherein said indentations are positioned relative to each other to provide a contiguous interface therebetween and a contiguous interface relative to the user's thumb, index finger and middle finger to facilitate controlled rolling between the user's fingers, and wherein said second and third indentations are more predominantly located on lower portions of the lateral surfaces.
