ABSTRACT:
A motion transmitting remote control assembly which prevents connection of the outer casing members of adjoining mechanical push-pull control sections unless the inner translating core members are connected. The assembly includes at least two inner translating core members for transmission of motion and being detachably connected for allowing connected and disconnected positions. At least two outer casing members slidably receive the inner translating core members and are detachably attached by a coupling nut for allowing attached and unattached positions. A spring-loaded finger member having a flange portion is pivotally housed in a longitudinal cavity in one of the core members. A head member is connected to the other core member by an extension member. The first-mentioned core member has a slot which terminates in a radial bore adjacent the longitudinal cavity for receiving the extension member and the head member. The finger member has a reactive surface which cooperates with an interaction surface on the head member for moving the finger member to a retracted position when the inner translating core members are connected in order to provide an operable position of the assembly whereby the outer casing members may be connected. Additionally, the second-mentioned inner translating core member engages a shoulder surface defined by its associated outer casing member to limit axial movement of the second core member.
