Abstract
Abstract An elongate inner tubular sleeve is slidably mounted within an outer tubular sleeve, with the inner sleeve mounting a plurality of actuator links to permit axial displacement of the inner sleeve relative to the outer sleeve, wherein the inner sleeve pivotally mounts an annular array of paddle blades at a lower distal end of the inner sleeve that are positioned exteriorly of the outer sleeve, whereupon axial displacement of the inner sleeve relative to the outer sleeve effects radial displacement of each paddle blade relative to the outer sleeve to permit a stirring thereof, with the actuator links projecting exteriorly to provide for a handle structure permitting ease of rotation of the stirring device within a container.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A stirring device, comprising, an outer tubular sleeve slidably mounted within an inner sleeve, the outer tubular sleeve defined by a predetermined internal diameter, and the inner tubular sleeve defined by a predetermined outer diameter, wherein the predetermined outer diameter is substantially equal to the predetermined internal diameter, and the outer tubular sleeve including an outer sleeve lower distal end spaced from an outer sleeve upper distal end, the inner sleeve including an inner sleeve lower distal end spaced from an inner sleeve upper distal end, and the outer sleeve and the inner sleeve coaxially aligned relative to one another about a common axis, and the inner sleeve including a first actuator link and a second actuator link mounted pivotally to the inner sleeve adjacent the inner sleeve upper distal end, wherein the first actuator link and the second actuator link effect coaxial displacement of the inner sleeve relative to the outer sleeve, and the inner sleeve lower distal end including a plurality of paddle members pivotally mounted to the inner sleeve lower distal end.
Claim 2
Dependent Claim
175 words
A stirring device, comprising, an outer tubular sleeve slidably mounted within an inner sleeve, the outer tubular sleeve defined by a predetermined internal diameter, and the inner tubular sleeve defined by a predetermined outer diameter, wherein the predetermined outer diameter is substantially equal to the predetermined internal diameter, and the outer tubular sleeve including an outer sleeve lower distal end spaced from an outer sleeve upper distal end, the inner sleeve including an inner sleeve lower distal end spaced from an inner sleeve upper distal end, and the outer sleeve and the inner sleeve coaxially aligned relative to one another about a common axis, and the inner sleeve including a first actuator link and a second actuator link mounted pivotally to the inner sleeve adjacent the inner sleeve upper distal end, wherein the first actuator link and the second actuator link effect coaxial displacement of the inner sleeve relative to the outer sleeve, and the inner sleeve lower distal end including a plurality of paddle members pivotally mounted to the inner sleeve lower distal end.
Claim 3
Dependent Claim
54 words
A device as set forth in claim 1 wherein the inner sleeve lower distal end includes a circular array of mounting flanges extending radially beyond the inner sleeve lower distal end and the outer sleeve, with each mounting flange projecting through the outer sleeve, and each mounting flange pivotally mounting a paddle member thereon.
Claim 4
Dependent Claim
130 words
A device as set forth in claim 2 wherein the outer sleeve includes a cylindrical array of outer sleeve first slots spaced above the outer sleeve lower distal end, and a circular array of outer sleeve second slots, each outer sleeve second slot is colinear with an outer sleeve first slot and spaced below one of said outer sleeve first slots and above the outer sleeve lower distal end, and each mounting flange is directed through one of said outer sleeve first slots, and each paddle member is received within one of said outer sleeve second slots in the first position and in abutment with the outer sleeve between one of said outer sleeve first slots and one of said outer sleeve second slots in the second axially displaced position.
Claim 5
Dependent Claim
118 words
A device as set forth in claim 3 wherein the inner sleeve includes an inner sleeve first slot diametrically aligned with an inner sleeve second slot adjacent the inner sleeve upper distal end and the first actuator link of a U-shaped configuration and the second actuator link of a U-shaped configuration, with the first actuator link pivotally mounted within the inner sleeve first slot and the second actuator link pivotally received within the inner sleeve second slot, and each actuator link including an abutment nose projecting within the inner sleeve for abutment with the outer sleeve upper distal end in the second position, and each actuator link including an outer lever arm projecting exteriorly of the outer sleeve.
