Abstract
Abstract A cleat for securing a line, cable or similar elongated members that has a base with a head and tail end portions. A pair of spaced walls are provided which project from the base, and opposing interior surfaces of the walls are inclined away from each other to form a slot to receive and secure an elongated member. The interior surfaces are inclined relative to each other at an angle of between eight and 20*. In addition, the interior surfaces have a plurality of parallel ridges and grooves sloping towards the head in portion of the base at an angle of between 20* and 50* to the plane of the base.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
152 words
A cleat for securing a line, cable or similar elongated members comprising a base having a head and tail portions, said base only having means for anchoring to a member, a pair of space walls projecting substantially normally from said base and integral therewith, the opposing interior surfaces of said walls being inclined away from each other substantially uniformly from said base to the outer edges of said walls to form a slot to receive and secure an elongated member, said interior surfaces being inclined relative to each other at an angle between about 8* and about 20*, said interior surfaces having a plurality of generally parallel ridges and grooves sloping toward said head end portion of said base at an angle of between 20* and 50* to the plane of said base, said ridges and grooves forming V-shapes which extend substantially to the bottom of said interior surfaces adjacent said base.
Claim 2
Dependent Claim
152 words
A cleat for securing a line, cable or similar elongated members comprising a base having a head and tail portions, said base only having means for anchoring to a member, a pair of space walls projecting substantially normally from said base and integral therewith, the opposing interior surfaces of said walls being inclined away from each other substantially uniformly from said base to the outer edges of said walls to form a slot to receive and secure an elongated member, said interior surfaces being inclined relative to each other at an angle between about 8* and about 20*, said interior surfaces having a plurality of generally parallel ridges and grooves sloping toward said head end portion of said base at an angle of between 20* and 50* to the plane of said base, said ridges and grooves forming V-shapes which extend substantially to the bottom of said interior surfaces adjacent said base.
Claim 3
Dependent Claim
17 words
The cleat of claim 1 wherein said ridges have an apex angle of between 40* and 100*.
Claim 4
Dependent Claim
28 words
The cleat of claim 1 wherein a bridge is provided between portions of the free ends of said walls extending toward said tail end portion of said base.
Claim 5
Dependent Claim
45 words
The cleat of claim 1 wherein said interior surfaces are inclined at an angle of about 14* relative to each other and wherein said slot is V-shaped and is open toward said head and tail end portions of said base to receive an elongated member.
Claim 6
Dependent Claim
55 words
The cleat of claim 4 wherein said ridges and grooves slope toward said head end portion of said base at an angle of about 45* to the plane of said base and the free ends of said walls and the adjacent portions of said ridges are chamfered to provide a lead-in surface to said slot.
Claim 7
Dependent Claim
66 words
The cleat of claim 1 wherein said sidewalls have lip portions at the free ends thereof facing generally away from said base and head and tail portions facing generally toward said head and tail portions of said base, and wherein some of said ridges and grooves extend to said lip portions and others of said ridges and grooves extend to said head portions of said sidewalls.
Claim 8
Dependent Claim
47 words
The cleat of claim 6 wherein said interior surfaces are inclined at an angle of about 14* relative to each other and said ridges and grooves slope toward said head end portion of said base at an angle of about 45* to the plane of said base.
Claim 9
Dependent Claim
21 words
The cleat of claim 7 wherein a bridge is provided between said tail portions of said sidewalls adjacent said lip portions.
Claim 10
Dependent Claim
96 words
The cleat of claim 1 wherein two pairs of spaced walls project from said base integrally therewith, the opposing interior surfaces of each of said pair of walls being inclined relative to each other at an angle between about 8* and 20*, said interior surfaces having a plurality of generally parallel ridges and grooves sloping toward said head end portion of said base at an angle of between 20* and 50* to the plane of said base, said ridges and grooves forming V-shapes which extend substantially to the bottom of said interior surfaces adjacent said base.
Claim 11
Dependent Claim
17 words
The cleat of claim 9 wherein said ridges have an apex angle of between 40* and 100*.
