Abstract
Abstract A rope attaching device for splicing or forming a loop within a synthetic or natural fiber rope. The device includes a splicer body that is formed in two separate sections. Each section includes at least one rope receiving channel that is concave in cross section for receiving a length of rope therein. The two sections may be positioned facing one another, sandwiching a rope. A sheath formed of heat-shrink plastic material is provided that may be mounted over the juxtaposed sections. The sheath material will shrink upon application of heat to firmly grip and clasp the splicer body sections together securely clamping the rope.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
210 words
A rope attaching device, comprising: a rope splicer body extending from a front end to a rear end in which the body has a pair of symmetrical body sections with first complementary concave channels formed therein between the front end and the rear end defining a rope passageway through the body to receive a rope section therein when the two sections are placed together; said pair of symmetrical sections having second complementary concave channels formed therein extending from the front and toward the rear end at a converging angle with respect to the first complementary concave channels to form a rope end receptacle to receive a rope end therein and form a rope loop between the rope end and the rope section forward of the front end when the two sections are placed together; said rope splicer body comprising a plurality of pointed rope gripping elements projecting into the concave channels to penetrate the rope section and the rope end to firmly grip the rope section and the rope end in said channels; and sheath means complementary to the exterior shape of the rope splicer body when the sections are placed together to encase the splicer body and securely hold the section firmly together and prevent the sections from separating.
Claim 2
Dependent Claim
210 words
A rope attaching device, comprising: a rope splicer body extending from a front end to a rear end in which the body has a pair of symmetrical body sections with first complementary concave channels formed therein between the front end and the rear end defining a rope passageway through the body to receive a rope section therein when the two sections are placed together; said pair of symmetrical sections having second complementary concave channels formed therein extending from the front and toward the rear end at a converging angle with respect to the first complementary concave channels to form a rope end receptacle to receive a rope end therein and form a rope loop between the rope end and the rope section forward of the front end when the two sections are placed together; said rope splicer body comprising a plurality of pointed rope gripping elements projecting into the concave channels to penetrate the rope section and the rope end to firmly grip the rope section and the rope end in said channels; and sheath means complementary to the exterior shape of the rope splicer body when the sections are placed together to encase the splicer body and securely hold the section firmly together and prevent the sections from separating.
Claim 3
Dependent Claim
18 words
The device as defined by claim 1 further comprising a hinge member joining said sections to one another.
Claim 4
Dependent Claim
29 words
The device as defined by claim 2 wherein said sections are formed of flexible plastic material; the hinge member being integral with said sections along a side edge thereof.
Claim 5
Dependent Claim
43 words
The device as defined in claim 1 wherein the concave channels form substantially cylindrical bores along axes and wherein the gripping elements project radially toward the axes a radial distance approximately equal to one half the distance from channel walls to the axes.
Claim 6
Dependent Claim
38 words
The device as defined by claim 4 wherein the rope gripping elements are conical, having bases on arcuate walls of said sections and wherein the diameter of the bases is substantially equal to one half the radial distance.
Claim 7
Dependent Claim
39 words
The device as defined by claim 5 where the cone shaped gripping elements are canted longitudinally to project radially and axially into the rope end and rope section to secure the rope end and rope section in the channels.
Claim 8
Dependent Claim
25 words
The device as defined by claim 1 wherein the rope end receptacle has a longitudinal axis that intersects the rope passageway adjacent the rear end.
Claim 9
Dependent Claim
33 words
The device as defined by claim 1 wherein the rope splicer body has an enlarged front end and a reduced rear end and is tapered between the front end and the rear end.
Claim 10
Dependent Claim
37 words
The device as defined by claim 1 wherein the sheath means includes an enlarged front end and a reduced end and is tapered from the front end to the rear end to complementarily receive the splicer body.
Claim 11
Dependent Claim
25 words
The device as defined by claim 6 wherein the cone shaped gripping elements are canted longitudinally toward the rear end of the rope splicer body.
Claim 12
Dependent Claim
191 words
A rope attaching device, comprising: a rope splicer body extending from a front end to a rear end in which the body has a pair of symmetrical body sections with complementary concave channels formed therein adjacent the rear end defining a rope end receptacle having an opening at the rear end of the body to receive a rope end therein; said pair of symmetrical sections having complementary recesses formed adjacent the front end defining an eyelet receiving cavity having an opening at the front end; an eyelet means mounted in the eyelet receiving cavity and extending outward through the opening and terminating in an eyelet section forward of the front end of the rope splicer body; said rope splicer body comprising a plurality of pointed rope gripping elements projecting into the concave channels to penetrate the rope end to firmly grip the rope and in said rope end receptacle; and sheath means complementary to the exterior shape of the rope splicer body when the sections are placed together to encase the splicer body and securely hold the section firmly together to securely interconnect the rope end and the eyelet means together.
Claim 13
Dependent Claim
191 words
A rope attaching device, comprising: a rope splicer body extending from a front end to a rear end in which the body has a pair of symmetrical body sections with complementary concave channels formed therein adjacent the rear end defining a rope end receptacle having an opening at the rear end of the body to receive a rope end therein; said pair of symmetrical sections having complementary recesses formed adjacent the front end defining an eyelet receiving cavity having an opening at the front end; an eyelet means mounted in the eyelet receiving cavity and extending outward through the opening and terminating in an eyelet section forward of the front end of the rope splicer body; said rope splicer body comprising a plurality of pointed rope gripping elements projecting into the concave channels to penetrate the rope end to firmly grip the rope and in said rope end receptacle; and sheath means complementary to the exterior shape of the rope splicer body when the sections are placed together to encase the splicer body and securely hold the section firmly together to securely interconnect the rope end and the eyelet means together.
Claim 14
Dependent Claim
39 words
The device as defined in claim 11 wherein the eyelet means includes a pivot base complementary to the eyelet receiving cavity and pivotably receivable therein; a shank extending through the opening from the pivot base to the eyelet section.
Claim 15
Dependent Claim
25 words
The device as defined in claim 11 wherein the eyelet receiving cavity and the rope end receptacle are axially aligned within the rope splicer body.
