Abstract:
A piston and connecting rod assembly includes a piston crown, a piston skirt, a connecting rod, and a bearing insert. The piston skirt is a component separate from the piston crown and is connected to the piston crown to provide a piston body. The bearing insert is a component separate from the piston crown and the piston skirt and is fixedly disposed within the piston body. A bearing surface of a connecting rod contacts the bearing insert to thereby movably associate the connecting rod and the piston body.
Abstract:
A flexible molded grip for an implement handle having a pattern on the surface of portions raised above adjacent areas, with the surfaces of the raised portions textured. The raised textured portions may extend in the range of about 0.5 mm to 2 mm above the intermediate smooth portions. The area of each of the raised portions may be in the range of about 100-200 percent (%) of the area of the intermediate spaces. The pattern of raised portions may include patterns such as polygonal, circular, oval and elliptical patterns. The method includes forming raised portions in a mold and forming textured surfaces on the raised portions after removal from the mold.
Abstract:
A flexible golf club grip having a brightly colored underlist of elastomeric material of a certain durometer and an outer layer of less durometer. The outer layer may have voids to expose portions of the underlist or the underlist may have portions thereof extend into the voids during molding. In another version, a brightly colored cover layer is molded over the underlist and a spiral wrapped strip of softer elastomer is molded thereover with the edges of the strip spaced to expose the original strip of the cover layer.
Abstract:
A changeable grip 12 for a shock imparting implement has a gripping sleeve 18 positioned on a handle sleeve 15 attached to a handle 14. A lower end of gripping sleeve 18 abuts a ledge 28 integrally formed in the handle sleeve 15. A threaded cap 20 compresses the gripping sleeve 18 against the ledge 28 to secure the grip 12 to the handle sleeve 15. Optional splines 40 on an outer surface of the handle sleeve 15 meshing with channels 42 in the gripping sleeve 18 function to prevent slippage or rotation during use.

A handle 14 with a changeable grip 12 for a shock imparting implement has a gripping sleeve 18 positioned on an end 24 of a handle 14 abutting a ledge 28 integrally formed in the handle 14. A threaded cap 20 compresses the gripping sleeve 18 against the ledge 28 to secure the grip 12 to the handle 14. Optional splines 40 on an outer surface of the handle 14 meshing with channels 42 in the gripping sleeve 18 function to prevent slippage or rotation during use.
Abstract:
A variable mass cap 20 for a shock imparting implement grip has a butt element 22 connected to a tubular portion 24 constructed to receive a selected mass 26, 28. The tubular portion 24 fits snugly within a recess 34 of a body 32, and is retained therein by the engagement of an annular ridge 36 with a first annular groove 30 disposed in an outer surface of the tubular portion 24. In an alternate embodiment, threaded portion 31 is received by and engaged by a corresponding threaded recess 34. The cap 20 is mechanically secured to the body 32 for providing a grip with a variable mass.
Abstract:
A light flexible hand grip and method of making with an inner tubular core of flexible rubber with apertures formed therein and an outer tubular cover disposed over the core with a lighter weight annular flexible foam spacer between the core and outer cover. The spacer may be formed by injecting curable material through the apertures. The apertures may be formed by inserting a mandrel in the core, punching the holes and removing the mandrel.
