Handle for sports or work equipment and equipment comprising the handle
A handle for sport equipment comprises a tubular body ( 7 ) which extends along a longitudinal axis (L) and has an outer peripheral surface ( 8 ) adapted to be grasped by a user and shaped with a plurality of longitudinal faces ( 9 ) placed side by side in correspondence of edges ( 10 ) adapted to facilitate the positioning of the finger joints of the gripping hand by the user. The edges ( 10 ) are arranged along at least one pair of helical or spiral paths that develop around said longitudinal axis (L) with mutually opposite sign to subdivide each of said longitudinal faces ( 9 ) into a plurality of areas or flat surfaces ( 11 ) sized to accommodate a corresponding phalanx of the gripping hand of the user, each of said areas or flat surfaces ( 11 ) being perimetrically delimited by at least one pair of edges ( 10, 10 ′) of each of the helical or spiral paths.
