Abstract
Abstract A device for pushing a linearly actuable member comprises a pushbutton, cable, and actuator assembly. The pushbutton is coupled to an end of the cable through a cam and cam follower arrangement such that pushing of the button is converted into a pulling force on the cable by camming a yoke attached to the cable. The other end of the cable is connected to the actuator assembly which pushes the member in response to application of a pulling force from the cable. The actuator assembly includes a pivotally mounted lever having two arms forming an acute angle, with the cable being connected to the end of one arm of the lever and the other arm of the lever abutting against the member to be moved, the lever being mounted so that a portion of the actuator body serves as a fulcrum for the entire lever.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
194 words
An actuator assembly for use in pushing a member in response to the pulling of an elongated, flexible cable comprising an actuator body, at least one link pivotally connected at one end to said actuator body and extending away from said member, and a lever having two arms forming an acute angle pivotally connected at its apex to the end of said link opposite said one end, the end of one of said arms abutting against said member when said link is in a first position, said one arm abutting against a portion of said body when said lever is pivoted about said link, abutment of said one arm against said body portion causing said link and lever to be pivoted toward said member in a rotational movement about said one end of said link as the other of said Arms is pulled toward the actuator body, said other arm being connected to said cable, whereby a pulling force applied to said cable causes said lever to pivot with respect to said link and said link to pivot with respect to said body thereby urging the end of said one arm against said member.
Claim 2
Dependent Claim
194 words
An actuator assembly for use in pushing a member in response to the pulling of an elongated, flexible cable comprising an actuator body, at least one link pivotally connected at one end to said actuator body and extending away from said member, and a lever having two arms forming an acute angle pivotally connected at its apex to the end of said link opposite said one end, the end of one of said arms abutting against said member when said link is in a first position, said one arm abutting against a portion of said body when said lever is pivoted about said link, abutment of said one arm against said body portion causing said link and lever to be pivoted toward said member in a rotational movement about said one end of said link as the other of said Arms is pulled toward the actuator body, said other arm being connected to said cable, whereby a pulling force applied to said cable causes said lever to pivot with respect to said link and said link to pivot with respect to said body thereby urging the end of said one arm against said member.
Claim 3
Dependent Claim
17 words
An actuater assembly according to claim 1, wherein said one arm is shorter than said other arm.
Claim 4
Independent Claim
138 words
A device for pushing a member comprising; a. a pushbutton, b. a flexible cable, c. connector means responsive to said pushbutton for pulling said cable, said connector means comprising: i. a housing, ii. an elongated member, connected at one end to said pushbutton and slideable in said housing, the other end of said elongated member including a camming surface, and iii. a cam follower yoke pivotally mounted on said elongated member one end of said flexible cable being connected to said yoke, said yoke adapted to engage said camming surface, said camming surface being shaped to cause said yoke to apply a pulling force to said one end of said flexible cable when said pushbutton is pushed, and d. actuator means for pushing said member in response to the application of a pulling force to said flexible cable.
Claim 5
Independent Claim
138 words
A device for pushing a member comprising; a. a pushbutton, b. a flexible cable, c. connector means responsive to said pushbutton for pulling said cable, said connector means comprising: i. a housing, ii. an elongated member, connected at one end to said pushbutton and slideable in said housing, the other end of said elongated member including a camming surface, and iii. a cam follower yoke pivotally mounted on said elongated member one end of said flexible cable being connected to said yoke, said yoke adapted to engage said camming surface, said camming surface being shaped to cause said yoke to apply a pulling force to said one end of said flexible cable when said pushbutton is pushed, and d. actuator means for pushing said member in response to the application of a pulling force to said flexible cable.
Claim 6
Dependent Claim
161 words
A device according to claim 3, wherein said actuator means comprises: i. an actuator body, ii. a link pivotally connected at one end to said actuator body and extending away from said member, and iii. a lever having two arms forming an acute angle pivotally connected at its apex to the end of said link opposite said one end, the end of one of said arms adapted to abut against said member, said other arm adapted to abut against a portion of said body such that said body portion can serve as a fulcrum around which said link can pivot with the lever toward said member when the lever is pivoted toward said member, said other arm being connected to said pulling member, whereby tension on said flexible cable causes said lever to pivot with respect to said link and said link to pivot with respect to said body thereby urging the free end of said one arm against said member.
Claim 7
Dependent Claim
18 words
A device according to claim 4, wherein said one arm is shorter than the other of said arms.
Claim 8
Dependent Claim
39 words
An actuator assembly according to claim 1, including two of said links pivotally connected to said actuator body, the lever being positioned between said links, with a portion of the actuator body between said links forming said body portion.
Claim 9
Dependent Claim
23 words
An actuator assembly according to claim 1, wherein the angle between said link and said other arm is greater than said acute angle.
Claim 10
Dependent Claim
20 words
An actuator assembly according to claim 7, wherein the angle between said link and said other arm is approximately 90*.
