Abstract
A control cable anchor for securing a control cable in an opening having an elongated body with a shouldered end, axial slots in the body surface and locking pawls positioned within the slots. The pawls have a first end spaced from the shouldered end of the body which cooperates with the shouldered end to sandwich a wall which defines the opening. The pawls have a fulcrum point which engages the bottom of the slots. The pawls are biased into their first or locking position but may pivot about the fulcrum to be retracted at least partially beneath the body surface for insertion through the opening.
Claims6
An anchoring device for securing a control cable conduit assembly to an opening in a support wall, having a predetermined thickness, comprising:
- (a) an elongated body having a shouldered end which is larger in size than said opening and a front end which is smaller;
- (b) axially extending slot means extending long the outer surface of said body;
- (c) locking pawl means positioned within said slot means, said pawl means having
- (1) a first end spaced from the shouldered end of said body by a distance equal to the predetermined thickness of said support wall;
- (2) a second end spaced from said first end,
- (3) a fulcrum point between said ends engaging the bottom of said slot means and about which said pawl pivots from a first position in which the first end is raised out of said slot means by a distance sufficient to interfere with axial movement of said anchoring device through the opening in said support wall and a second position permitting movement of said anchoring device through said opening;
- and
- (4) a groove in the outer surface of said pawl means between said fulcrum point and second end thereof;
- (d) an annular groove extending circumferentially along the outer surface of said body, said annular groove having substantially the same width and depth as said groove in the outer surface of said pawl means, the annular groove and the groove in the pawl means being substantially aligned;
- and
- (e) an annular ring, disposed within said circumferential groove in said body and said groove in said pawl means, to bias said pawl means into said first position and to hold said pawl means against axial movement in said slot means.
