  • Patent number: 5682797
    Abstract: A conduit length adjustment device including a tubular housing slidably supporting a cylindrical slider member (24), the housing including a box-like access opening for receiving a U-shaped lock button (26). A pair of lugs (52, 54) are disposed on the exterior of the side walls (38) and each of the legs of the lock button (26) includes a pair of holes (56, 58) for co-acting with the lugs (52, 54) for defining detents for retaining the lock button (26) in unlocked and locked positions respectively. In addition, a pair of latch levers (60) extend parallel to the legs of the lock button (26) and have ramps leading to flat ends for snapping under and abutting a pair of co-acting latch abutments (62), which also have ramps (64, 66) leading to flat abutment surfaces whereby independent and simultaneous forces must be applied to the latch levers (60) and the legs of the lock button (26) to enable removal of the lock button (26) from the locked position.

  • Patent number: 5493934
    Abstract: A remote control cable assembly (10) includes a conduit (12) with a core element (24) slidably supported in the conduit (12). Slugs (30, 32) are die cast on each end of the core element (24) for connection to various controlling and controlled devices to transmit tensile forces therebetween. At least one slug (32) is formed with a teardrop shape having a spherically rounded head (34) and a frustum tail (36). The end (28) of the core element (24) is embedded within the slug (32). The twisted strands of the core element (24) are fanned over a segment (50) and embedded within the slug (32) to improve adhesion. During the die casting formation process, a sprue (52) injects molten zinc into a die cavity (44) near a truncated tip (38) of the frustum tail (36). The sprue (52) location and angle (I) decreases the possibility of unwanted core element (24) movement during the pressurized injection of molten zinc thereby improving cable assembly tolerances.

  • Patent number: 5272934
    Abstract: A motion transmitting remote control cable assembly (10) comprises a motion transmitting core element (12) slideably supported in a first conduit (14). The assembly (10) also includes a support fitting (20) for supporting the first conduit (14) as it passes through a slot (22) in a support structure (24). The support fitting (20) includes first and second sides (26,28) with guides (30) along the sides for sliding into engagement with the slot in the support structure and retaining the support fitting in the slot. The support fitting (20) finally includes at least one receiving opening (32) extending transversely to the first side (26) for receiving at least one conduit (14) transversely of the sides (26,28).

  • Patent number: 5261293
    Abstract: A motion transmitting remote control cable assembly (10) has a motion transmitting core element (12) slideably supported by first and second conduits (14,16), wherein the first conduit (14) telescopingly engages within the second conduit (16) between a fully inserted or "compressed" position and an extended position. The assembly also includes a spring (18) disposed within the second conduit (16) to interact between the first and second conduits (14,16). The assembly may include a locking mechanism (30) between the first and second conduits (14, 16) to maintain the two conduits in a predetermined relationship with respect to one another.

  • Patent number: 5241879
    Abstract: A motion transmitting remote control assembly (10) of the type for transmitting motion in a curved path includes a terminal member (36) for interconnecting an extending length of a core element and a control member (24). The terminal member (36) has a hole (38) passing therethrough in which a bushing (44) is disposed. The bushing (44) includes a passageway (48) extending completely through the bushing (44) between an insertion end (50) and a distal end (46) for connecting the terminal member (36) with a control pin (28) of the control member (24). The bushing (44) includes at least one slot (56a) oriented along the core element which enables the bushing (44) to flex transversely to the direction of the core element to release the control pin (28) from the bushing (44) in response to a force (F) applied therebetween when the control pin (28) is inserted into the passageway (48) from the distal end (46 ) of the bushing (44) instead of through the insertion end (50).

  • Patent number: 5156063
    Abstract: A motion transmitting remote control assembly including a conduit and a motion transmitting core element moveably supported by the conduit. A female member matingly receives a male member in one of various positions for adjustment of the relative length of one of the conduit and the core element. The female member includes a radially flexible pawl which engages the external surface of the male member to allow axial positioning of the male member relative to the female member. A collar surrounds and is slidably disposed over the female member for preventing relative movement between the male and female members.

  • Patent number: 5142933
    Abstract: A motion transmitting remote control assembly (10,10',10") includes a flexible conduit (12,12',12") and a flexible core element (16,16',16") movably supported by the conduit (12,12',12"). A slider member (26,26',26") is fixedly attached to either the conduit (12,12',12") or the core element (16,16',16"), depending upon whether the application is a length adjustable conduit (12,12',12") or a length adjustable core element (16,16',16"). A support member (18,18',18") slideably supports the slider member (26,26',26") while preventing rotational movement therebetween. A locking member (38,38',38") is continuously biased toward locking engagement with the slider member (26,26',26") by a spring (50,50',50").

  • Patent number: 5014569
    Abstract: A motion transmitting remote control assembly of the type for transmitting forces along a curved path. The assembly (10) includes a conduit assembly (12) having first (16) and second (17) end fittings thereon for mounting to a support structure. A flexible core element (30) is moveably supported by the conduit assembly (12) and has a slug (34) secured to one end thereof for movement with the core element (30). A shaft (22, 22') is disposed about and retained on the core element (30) by the slug (34). The shaft (22, 22') defines a channel (32, 32') with an opening (37, 37') at one end thereof for receiving the slug (34) into the channel (32, 32'). A plug (33) is disposed in the opening (37, 37') to retain the slug (34) in the channel (32, 32'). A terminal member (36) is molded to the one end of the shaft (22, 22') about the plug (38) and the opening (37, 37') for connection to a controlled member.
