ABSTRACT:
A line cleat for use in a sailboat environment having a base plate and a pair of cam elements pivotally mounted on the base plate about spaced axes normal to the base plate. The cam elements have eccentric confronting faces that coact to define a line-gripping nip therebetween. The cam elements are displaceable about the axes of the cam elements to permit a line to enter the nip and to pass therethrough in one direction only axially of the line and to hold the line against retrogressive movement in the opposite axial direction. Inclined surface cooperate to define a V-shaped gap into the nip. The V-shaped gap is located above the nip. The inclined surfaces have serrations thereon which lie (seen from above) tangent to circles, the center of which are coincident with the axes of the cam elements and which are inclined in the opening direction and are parallel to each other to effect, upon movement of the line toward the nip, a displacement of the cam elements an amount sufficient to receive the line within the nip without necessitating an axial movement of the line therethrough.
