Abstract
Abstract An insulated staple is formed by a U-shaped body member and a piece of flexible, plastic tubing bent in a U-shaped configuration and installed on the body member. The plastic tubing is cut along a longitudinal wall portion to form a longitudinally extending opening at the central region of the tubing. The insulated staple is then assembled by inserting the opposed and parallel legs of the body member through the longitudinal opening and out through the axial ends of the tubing so that the body member is lined along its inner periphery between the end portions of the tubing mounted on the opposed and parallel legs. The method for making the insulated staple comprises cutting the longitudinal opening in the tube, bending the tube in a U-shaped configuration and inserting the legs of the body member through the axial ends of the tubing so that the pointed tips are exposed and the inner periphery of the staple is lined between the end portions of the tubing on the parallel legs.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
A staple for anchoring objects to a base comprising: a generally U-shaped body member having substantially parallel legs, each leg being adapted for penetrating a base and a connecting bridge section joining the legs; and a section of nonmetallic flexible tubing bent in a U-shaped configuration and fitted on the U-shaped body member with opposite end portions of the tubing being positioned coaxially on the respective legs of the body member, completely encircling the the portions of the respective legs adjacent the bridge section and exposing the ends thereof, the section of tubing having an intermediate portion connecting the end portions and extending along the bridge section to line a substantial part of the inner periphery of the U-shaped body member.
Claim 2
Dependent Claim
121 words
A staple for anchoring objects to a base comprising: a generally U-shaped body member having substantially parallel legs, each leg being adapted for penetrating a base and a connecting bridge section joining the legs; and a section of nonmetallic flexible tubing bent in a U-shaped configuration and fitted on the U-shaped body member with opposite end portions of the tubing being positioned coaxially on the respective legs of the body member, completely encircling the the portions of the respective legs adjacent the bridge section and exposing the ends thereof, the section of tubing having an intermediate portion connecting the end portions and extending along the bridge section to line a substantial part of the inner periphery of the U-shaped body member.
Claim 3
Dependent Claim
51 words
A stAple for anchoring as defined in claim 1 wherein the intermediate portion of the section of non-metallic tubing contains a longitudinally extending opening and the section of tubing is positioned on the body member with the opening exposing the bridge section along the outer periphery of the U-shaped body member.
Claim 4
Dependent Claim
29 words
A staple for anchoring as defined in claim 2 wherein the section of tubing containing the longitudinally extending opening partially envelops the bridge section of the U-shaped body member.
Claim 5
Dependent Claim
41 words
A staple for anchoring as defined in claim 1 wherein the intermediate portion of the section of tubing contains an opening extending longitudinally along the bridge section and exposing the outer periphery of the U-shaped body member between the parallel legs.
Claim 6
Dependent Claim
57 words
A staple for anchoring as defined in claim 1 wherein the U-shaped body member is formed by a wire stock having a preselected diameter; and the section of non-metallic tubing has an inside diameter substantially equal to the diameter of the wire stock to permit the section of tubing to be slipped onto the U-shaped body member.
Claim 7
Dependent Claim
33 words
A staple for anchoring as defined in claim 5 wherein the U-shaped body member is formed by a metallic wire stock; and the section of tubing is formed from an electrically nonconductive plastic.
Claim 8
Dependent Claim
150 words
An insulated staple for holding conduits and the like comprising: a metallic body member including two generally parallel legs having pointed tips at free ends of the legs for driving the respective legs into an anchoring body, and a bridging section integrally connected to the ends of the legs opposite the free ends and extending between the parallel legs to join the legs and the section in a U-shaped configuration; and a tube formed from an insulating material and extending along the bridging section and onto each of the opposite ends of the parallel legs, the wall of the tube having an opening extending longitudinally along the tube a limited distance approximately equal to the length of the bridging section, the tube being positioned on the body member to expose the body member at one side of the bridging section facing away from the pointed tips of the parallel legs.
Claim 9
Dependent Claim
150 words
An insulated staple for holding conduits and the like comprising: a metallic body member including two generally parallel legs having pointed tips at free ends of the legs for driving the respective legs into an anchoring body, and a bridging section integrally connected to the ends of the legs opposite the free ends and extending between the parallel legs to join the legs and the section in a U-shaped configuration; and a tube formed from an insulating material and extending along the bridging section and onto each of the opposite ends of the parallel legs, the wall of the tube having an opening extending longitudinally along the tube a limited distance approximately equal to the length of the bridging section, the tube being positioned on the body member to expose the body member at one side of the bridging section facing away from the pointed tips of the parallel legs.
Claim 10
Dependent Claim
49 words
An insulated staple as defined in claim 7 wherein the opening in the tube wall extends axially of the tube along the entire one side of the bridging section between the legs and also exposes at least portions of the integral connections between the bridging section and the legs.
Claim 11
Dependent Claim
100 words
An insulating sleeve for use in stapling a conduit in an insulated condition comprising: a tube section formed from a flexible insulating material and having an opening in the wall of the tube section, the opening extending longitudinally of the section along a region of the tube section intermediate the axial ends of the tube section and being defined by two generally longitudinally extending edges intermediate oppositely located longitudinal boundary edges, the two longitudinally extending edges lying in a longitudinal plane of the tube section offset from the tube axis toward the side of the tube section defining the opening.
Claim 12
Dependent Claim
100 words
An insulating sleeve for use in stapling a conduit in an insulated condition comprising: a tube section formed from a flexible insulating material and having an opening in the wall of the tube section, the opening extending longitudinally of the section along a region of the tube section intermediate the axial ends of the tube section and being defined by two generally longitudinally extending edges intermediate oppositely located longitudinal boundary edges, the two longitudinally extending edges lying in a longitudinal plane of the tube section offset from the tube axis toward the side of the tube section defining the opening.
Claim 13
Dependent Claim
34 words
The insulating sleeve as defined in claim 9 wherein the width of the opening between the two longitudinal edges is less than the width of the opening in the vicinity of the boundary edges.
Claim 14
Dependent Claim
19 words
An insulating sleeve as defined in claim 9 wherein the flexible insulating material is formed from a plastic material.
