Adjustment lock with lock fingers

A motion-transmitting remote-control assembly (10) for transmitting motion along a curved path comprising:

• a flexible motion-transmitting core element (12),
• a conduit (16, 18) slidably supporting said core element (12),
• adjustment means disposed along one of said core element and said conduit for adjusting the length of one of said core element and said conduit and including a lock button (26) movable between an unlocked position allowing adjustment of the length and a locked position for preventing any change in the length, said adjustment means including a housing member (22) and a slider member (24) in telescoping relationship with said housing member (22), said lock button (26) being supported by said housing member (22) for radial movement between said unlocked and locked positions, said lock button (26) being U-shaped to include a base and parallel legs extending from said base, said slider member (24) and said lock button (26) having co-acting teeth (28, 30) for interlocking engagement in said locked position to prevent relative axial movement between said housing member (22) and said slider member (24) to prevent any change in the length, said detents being disposed along said legs of said lock button (26),
• an unlocked detent (52, 58) for holding said lock button (26) in said unlocked position and a locked detent (52, 56;
• 54, 58) for holding said lock button (26) in said locked position,
• a mechanical latch (60, 62) movable to a latched position for mechanically blocking movement of said lock button (26) from said locked position,
• said mechanical latch being spaced axially from said locked and unlocked detents and movable independently of said detents from said latched position whereby independent forces must be applied to said detents and said latch to remove said lock button (26) from said locked position, said latch including at least one latch lever (60) extending axially from at least one of said legs and at least one latch abutment (62) disposed on said housing member (22), one of said latch levers (60) being connected to each of said legs adjacent the distal ends of said legs with said latch levers (60) extending in a cantilevered fashion parallel to and spaced from said legs toward said base of said lock button (26).
