Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 234 words
An adapter to enable a non-standard sized battery to be operatively placed in a battery compartment designed to house a standard sized battery which is larger than the non-standard size battery, said adapter comprising an elongated, molded plastic tubular body having a transverse wall integral with one end thereof and with an opening through said end wall, said tubular body having a shorter axial length than a non-standard sized battery whereby the non-standard sized battery extends outwardly of said tubular member when the non-standard sized battery is contained within said adapter, said tubular body further including a plurality of inwardly directed and axially extending resilient ribs formed integrally with said transverse end wall and the inside surface of said tubular body for releasably holding a portion of the non-standard sized battery contained within said adapter, each of said ribs including a notch extending axially from the inner surface of said transverse end wall and along at least a portion of the inwardly directed edge of said ribs, the opening in said transverse end wall including a plurality of cuts therein that correspond to the shape and depth of each said notch in each said rib whereby the unnotched portion of each said rib contacts and resiliently retains the non-standard sized battery and whereby said adapter is capable of being manufactured by a molding process in a single operation utilizing cooperating male and female molds.
Claim 2
Dependent Claim 234 words
An adapter to enable a non-standard sized battery to be operatively placed in a battery compartment designed to house a standard sized battery which is larger than the non-standard size battery, said adapter comprising an elongated, molded plastic tubular body having a transverse wall integral with one end thereof and with an opening through said end wall, said tubular body having a shorter axial length than a non-standard sized battery whereby the non-standard sized battery extends outwardly of said tubular member when the non-standard sized battery is contained within said adapter, said tubular body further including a plurality of inwardly directed and axially extending resilient ribs formed integrally with said transverse end wall and the inside surface of said tubular body for releasably holding a portion of the non-standard sized battery contained within said adapter, each of said ribs including a notch extending axially from the inner surface of said transverse end wall and along at least a portion of the inwardly directed edge of said ribs, the opening in said transverse end wall including a plurality of cuts therein that correspond to the shape and depth of each said notch in each said rib whereby the unnotched portion of each said rib contacts and resiliently retains the non-standard sized battery and whereby said adapter is capable of being manufactured by a molding process in a single operation utilizing cooperating male and female molds.
Claim 3
Dependent Claim 40 words
The adapter according to claim 1 wherein said ribs extend generally chordally inwardly from the inside wall of said tubular body and wherein said ribs have a free end that is spaced from the inside surface of said tubular body.
