Shock and vibration absorbent handle
First Claim
1. A shock and vibration handle for application to the hand gripping portion of a normal handle on an impacted, vibration sensitive item, characterized in that it comprises:
- (a) a tubular inner isolation shell of shock and vibration absorbent material adapted to be mounted on the hand gripping portion of a normal handle;
(b) a tubular outer rigid shell having an outer periphery and being mounted around said tubular inner isolation shell of shock and vibration absorbent material and comprising two elongated equal shell portions which do not touch each other;
(c) means for holding said tubular inner and outer shells in mating position on the hand gripping portion of a normal handle; and
,(d) a handle covering material operatively mounted around the outer periphery of said tubular outer shell.

Abstract
A shock and vibration handle for application to the hand gripping portion of the normal handle of an impacted, vibration sensitive item, such as, a tennis racket, a racquetball racket, a golf club, a baseball bat, and other impact devices, such as hammers, and the like. The shock and vibration absorbent handle includes an inner tubular isolation shell of shock and vibration absorbent material mounted on the hand gripping portion of the normal handle. An outer tubular shell is mounted around shock absorbent material, and has it wrapped therearound a covering material. The absorbent material may be employed as longitudinal strips, spaced around the periphery of the handle or an integral, single piece tubular member. The inner tubular shells of absorbent material may be mounted on an inner tubular mounting shell which is mounted on the handle, and which has operatively mounted therein a cantilever spring beam having a weight on the free end thereof. In the last described handle the absorbent material may be deleted since the spring is also a vibration damper.

6. A shock and vibration handle for application to the hand gripping portion of a normal handle on an impacted, vibration sensitive item, characterized in that it comprises:
-
(a) a tubular inner isolation shell of shock and vibration absorbent material adapted to be mounted on the hand gripping portion of a normal handle; (b) a tubular outer shell having an outer periphery and being mounted around said tubular inner isolation shell of shock and vibration absorbent material and comprising two elongated equal shell portions which do not touch each other; (c) means for holding said tubular inner and outer shells in mating position on the hand gripping portion of a normal handle; (d) a handle covering material operatively mounted around the outer periphery of said tubular outer shell; (e) said tubular inner isolation shell of shock and vibration absorbent material comprising a plurality of strips of said material, evenly spaced longitudinally about the hand gripping portion of a normal handle; (f) said tubular inner isolation shell of shock and vibration absorbent material being adapted to be mounted on the handle gripping portion of a normal handle by a tubular inner mounting shell which has one end fixedly mounted on the hand gripping portion of the normal handle; and
,(g) an elongated damping spring beam disposed in said tubular inner mounting shell, said beam having one end attached to the end of the tubular inner mounting shell that is adapted to be fixed to a normal handle, and the other end of said beam carrying a weight which is free to vibrate within the tubular inner mounting shell when the item is impacted.
