Abstract
A grip for a sports racquet, tool or other article adapted to be hand-held when in use. The grip defines an internal vacuum chamber which communicates with ambient surroundings through one or passageways in the grip. The passageways are covered or filled with a porous, permeable material. A port with removable plug communicates with the internal vacuum chamber. When, the grip is wetted and a vacuum applied to the chamber, moisture that accumulates on the surface of the grip will be drawn by a wicking action into the chamber to maintain the grip in a substantially dry condition.
Claims14
A grip for an article adapted to be manually grasped by user, said grip comprising:
- a) an elongated body having an external surface and defining an internal chamber, said internal chamber having an internal surface;
- b) said body defining at least one passageway extending through said body to said chamber and communicating said chamber with the ambient environment;
- c) a porous material extending across said passageway, said porous material being permeable;
- d) said body defining a port communicating with said chamber;
- e) a removable plug in said port;
- and
- f) valve means in said grip for selectively extracting air from said chamber to impose a vacuum therein.
A grip for an article adapted to be manually grasped by the user, said grip comprising:
- a) an elongated body having an external surface and defining an internal chamber;
- b) said body being of a material defining pores and having a predetermined permeability;
- c) a port in said body extending from said external surface to said internal chamber;
- and
- d) valve means in said grip to permit selective imposition of a vacuum in said chamber.
A method of maintaining a grip for an article which is adapted to be grasped by user in a dry condition, said method comprising:
- a) providing an internal chamber with said grip;
- b) providing at least one passageway communicating said internal chamber with ambient surroundings;
- c) covering said passageway with a porous material having a predetermined permeability and;
- d) applying a vacuum to said internal chamber creating a wicking effect inward from the surface of said grip into the vacuum chamber causing moisture to migrate into said vacuum chamber.
