A motion transmitting assembly (10) for transmitting motion in a curved path by a core element (12) is movably supported in a conduit (14) which is, in turn, supported by a ferrule (16). A slotted swivel tube (24) is supported by the ferrule (16) and a terminal (24) is slidably disposed in the swivel tube (24). The assembly is characterized by the terminal (28) having a cross pin bore (30) and a cross pin (32) disposed in the cross pin bore (30), the cross pin (32) having a hole (34) extending transversely or diametrically therethrough with the core element (12) extending through the hole (34) to retain the cross pin (32) in the bore (30). The cross pin (32) extends through the cross pin bore (30) and out of each of the slots (26). A crimped section (36) of the terminal (28) is deformed into gripping engagement with the core element (12) to retain the terminal (28) to the core element (12).

Method of fabrication of a slotted swivel tube

Slotted swivel tube

A motion transmitting remote control assembly has a conduit, a core element, and an end fitting molded about one end of the conduit. The end fitting is generally cylindrical and has a plurality of annular locking grooves and is fitted with an O-ring seal. A connector is molded separately from the end fitting and has snap-lock tabs for attachment to a support structure. A receptacle extends into the connector from one end thereof and is accessible from above through a transverse passage. The end fitting is insertable axially into the receptacle through its open end to support the connector for rotation about the end fitting. The O-ring provides a fluid-tight seal between the end fitting and connector. The end fitting is retained in the receptacle by a locking member having U-shaped locking portions that are extendible through the transverse passage into nesting engagement with the locking grooves of the end fitting to secure the end fitting against removal from the receptacle while retaining the relative rotatability of the connector and end fitting.

Remote control assembly having rotatable end fitting

A motion transmitting remote control assembly (10) which includes a conduit (12) and a motion transmitting core element (14) moveable longitudinally within the conduit (12) to transmit motion. A slider member is slidably disposed in an adjustment body (26). The slider member (70) moves inward into the adjustment body (26) transversely to a central axis (16) of the core element (14) to a locked position and moves outward transversely to the central axis (16) to an unlocked position to permit relative axial movement between the adjustment body (26) and slider member (70). A terminal receptacle (98) is disposed on the slider member (70) which accepts a control member into coupling attachment transverse to the central axis (16). The control member remains attached to the slider member (70) while the slider member (70) moves to the unlocked position to permit relative movement between the control member and the adjustment body (26).

Oppositely toothed core adjust having integral inner member and control

A motion transmitting remote control assembly (10) for transmitting forces along a curved path by a flexible core element (26) slidably disposed witin a flexible conduit (12). The assembly (10) includes an elongated member (62) for adjusting the longitudinal position of the conduit (12) by being slidably disposed within a passageway (68) of a support member (32). A locking clip (86) is movable between a disengaged position for permitting relative longitudinal movement between the elongated member (62) and the base (32) and an engaged position for preventing longitudinal movement therebetween. The improvement resides in the elongated member (62) being rotatably supported on the conduit (12) to allow rotation of the conduit (12) relative to the support member (32) while in an engaged position.
