Abstract
Abstract A motion transmitting remote control assembly of the type for transmitting forces along a curved path by a motion transmitting core element, the assembly comprising a flexible guide means or conduit, a flexible motion transmitting core element movably supported by the guide means with the ends thereof extending from the ends of the guide means, a support member for supporting the guide means, and locking means engageable with the guide means for controlling the longitudinal movement thereof relative to the support member. The locking means includes a plurality of resilient fingers supported circumferentially about the guide means by an annular ring wherein the fingers are held in gripping engagement with the guide means, the fingers contacting the surface of the guide means at an acute angle. The resilient fingers allow relative movement between the guide means and the support member in one direction while normally preventing such movement in the opposite direction. Release means in the form of a cylindrical member slidably disposed on the guide means is provided to disengage the fingers from the guide means to allow free axial movement in both directions.

Claim 1
Independent Claim
217 words
A motion transmittIng remote control assembly of the type for transmitting forces along a curved path by a motion transmitting core element, said assembly comprising: a flexible guide means, a flexible motion transmitting core element movably supported by said guide means with the ends thereof extending from the ends of said guide means, a support member, said support member normally slidably supporting said guide means when said support member is in supporting relationship to said guide means to permit axial movement of said guide means with respect to said support member, and locking means supported by said support member and engageable with said guide means for controlling the axial sliding movement of said guide means relative to said support member; said locking means including a plurality of resilient fingers supported circumferentially about said guide means and extending toward said guide means to establish gripping engagement therewith, said fingers contacting the surface of said guide means at an acute angle whereby said fingers allow relative movement between said guide means and said support member in one direction when a force sufficient to overcome the gripping engagement is applied to said guide means while normally preventing such movement in the opposite direction when said guide means is supported by said support means and said fingers engage said guide means.
Claim 2
Dependent Claim
217 words
A motion transmittIng remote control assembly of the type for transmitting forces along a curved path by a motion transmitting core element, said assembly comprising: a flexible guide means, a flexible motion transmitting core element movably supported by said guide means with the ends thereof extending from the ends of said guide means, a support member, said support member normally slidably supporting said guide means when said support member is in supporting relationship to said guide means to permit axial movement of said guide means with respect to said support member, and locking means supported by said support member and engageable with said guide means for controlling the axial sliding movement of said guide means relative to said support member; said locking means including a plurality of resilient fingers supported circumferentially about said guide means and extending toward said guide means to establish gripping engagement therewith, said fingers contacting the surface of said guide means at an acute angle whereby said fingers allow relative movement between said guide means and said support member in one direction when a force sufficient to overcome the gripping engagement is applied to said guide means while normally preventing such movement in the opposite direction when said guide means is supported by said support means and said fingers engage said guide means.
