Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
A rotary input type regulator adapted to move a closure between opened and closed positions comprising a rigid track having a first end parallel to the direction of movement of the closure and a second end formed in a spiral configuration; a polymeric tape situated within the track and having a first end attached to the closure and a second end positioned within the portion of the track formed in a spiral configuration; a power transmission arm having one end rotatably mounted in the center of the spiral configuration; a drive block connected to both the second end of the polymeric tape and slideably connected to the power transmission arm and the track so as to move the second end of the tape within the end of the track formed in a spiral configuration with rotation of the power transmission arm; and a rotary input means attached to the rotatably mounted end of the power transmission arm.
Claim 2
Dependent Claim
157 words
A rotary input type regulator adapted to move a closure between opened and closed positions comprising a rigid track having a first end parallel to the direction of movement of the closure and a second end formed in a spiral configuration; a polymeric tape situated within the track and having a first end attached to the closure and a second end positioned within the portion of the track formed in a spiral configuration; a power transmission arm having one end rotatably mounted in the center of the spiral configuration; a drive block connected to both the second end of the polymeric tape and slideably connected to the power transmission arm and the track so as to move the second end of the tape within the end of the track formed in a spiral configuration with rotation of the power transmission arm; and a rotary input means attached to the rotatably mounted end of the power transmission arm.
Claim 3
Dependent Claim
21 words
