Abstract

Abstract A handle adapter for hand molding around an existing handle and constructed in a manner enabling the user to shape the external surface of the adapter to conform to the grip of the user's hand. The material to be molded is contained in a pouch having flexible walls and end closures. The size of the pouch is such that the total volume which it could contain is much larger than the volume of the moldable material therein. One half of the pouch has a cross-sectional area smaller than the cross-sectional area of the other half, whereby the smaller cross-section half of the pouch can be pushed inside the larger cross-section half of the pouch and the material therebetween becomes trapped between two concentrically positioned flexible walls. When the walls of the smaller half pouch are supported by a solid structure, the moldable material then envelops such structure. When pressure is applied externally preferentially at certain locations on the walls of the larger half pouch, the trapped moldable material has no way to escape and is forced to rearrange its shape to match the external contour imposed on the outer wall on which such pressure is being applied. The moldable material is then caused to harden while the pressure remains applied. This results in obtaining a molded external surface which thus matches the configuration of the means by which the pressure was externally applied.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 133 words
In combination, a handle; and an adapter surrounding a portion of the handle and configured to fit a user's grip, including a pair of elongate pouches each having a flexible deformable wall defining a closed end and an open end, means for joining the open ends of the pouches in overlapping relationship, one of the pouches being folded inside the other one of the pouches, the inside pouch being in intimate contact with the handle portion and there being defined an internal volume between the walls of the pouches which surrounds the handle portion, the volume being filled with a material which was initially moldable by gripping the outside pouch and which thereafter hardened to provide the adapter with a plurality of deformations for receiving the fingers and thumb of the user's hand.
Claim 2
Dependent Claim 133 words
In combination, a handle; and an adapter surrounding a portion of the handle and configured to fit a user's grip, including a pair of elongate pouches each having a flexible deformable wall defining a closed end and an open end, means for joining the open ends of the pouches in overlapping relationship, one of the pouches being folded inside the other one of the pouches, the inside pouch being in intimate contact with the handle portion and there being defined an internal volume between the walls of the pouches which surrounds the handle portion, the volume being filled with a material which was initially moldable by gripping the outside pouch and which thereafter hardened to provide the adapter with a plurality of deformations for receiving the fingers and thumb of the user's hand.
Claim 3
Dependent Claim 11 words
The combination of claim 1 wherein the moldable material includes plaster.
Claim 4
Dependent Claim 11 words
The combination of claim 1 wherein the moldable material includes resin.
Claim 5
Dependent Claim 12 words
The combination of claim 1 wherein the moldable material includes silicone rubber.
Claim 6
Dependent Claim 29 words
The combination of claim 1 wherein the pouches are dimensioned relative to the handle so that the overlapping portions of the pouches and the joining means are not folded.
Claim 7
Dependent Claim 46 words
The combination of claim 1 and further comprising an internal sealing seam located substantially tranversally with respect to the pouch longitudinal axes normally separating the interiors of the pouches and which has been ruptured to permit mixing of a reacting pair of components of the material.
Claim 8
Dependent Claim 41 words
The combination of claim 1 and further comprising a capsule inside one of the pouches and normally containing a catalyst, the capsule having been ruptured to permit mixing of the catalyst with the material in the internal volume separating the pouches.
Claim 9
Dependent Claim 37 words
The combination of claim 1 and further comprising an external clamp normally located between the pouches about the overlap joint and which has been removed to permit mixing of a reacting pair of components of the material.
