Abstract
Abstract A material retainer strip for holding gravel in a roadway, lining a flower bed or garden plot and generally maintaining the integrity of two separate surface materials, comprising elongated, flexible resilient strips of material having a substantially C-shaped cross-section, the base lip thereof being wider than the top lip, the base lip being secured to a surface by stakes. Included are a plurality of splice joints of various shapes for connecting the ends of the strips either in alignment or to permit execution of an abrupt turn in direction.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
A loose material retainer strip comprising an elongated flexible strip having a substantially C-shaped cross-section, a base lip thereof being wider than a top lip thereof, a plurality of longitudinally spaced apertures in the base lip for securing the strip in place with appropriate stakes, the material of said strip being flexible and resilient to substantially retain its C-shaped cross-section, whereby upon installation the base lip is secured to the ground with stakes with the open side of the C-shaped strip facing the loose material to be retained, the loose material being filled or pulled over said base lip.
Claim 2
Dependent Claim
99 words
A loose material retainer strip comprising an elongated flexible strip having a substantially C-shaped cross-section, a base lip thereof being wider than a top lip thereof, a plurality of longitudinally spaced apertures in the base lip for securing the strip in place with appropriate stakes, the material of said strip being flexible and resilient to substantially retain its C-shaped cross-section, whereby upon installation the base lip is secured to the ground with stakes with the open side of the C-shaped strip facing the loose material to be retained, the loose material being filled or pulled over said base lip.
Claim 3
Dependent Claim
38 words
A retainer strip as set forth in claim 1 wherein the spaced apertures are positioned near the outer edge of the base lip such that the center line axis of said apertures do not intersect the top lip.
Claim 4
Dependent Claim
114 words
A loose material retainer strip comprising an elongated flexible strip having a substantially C-shaped cross-section, a base lip thereof being wider than a top lip thereof, a plurality of longitudinally spaced apertures in the base lip for securing the strip in place with appropriate stakes, the material of said strip being flexible and resilient to substantially retain its C-shaped cross-section, and including splicing means for connecting the ends of adjacent retainer strips together, said splicing means comprising an elongated sleeve segment having a C-shaped cross-section similar to that of the retainer strip and including longitudinal grooves along the outer edge of said sleeve segment for telescopingly receiving adjacent ends of said retainer strips therein.
Claim 5
Dependent Claim
114 words
A loose material retainer strip comprising an elongated flexible strip having a substantially C-shaped cross-section, a base lip thereof being wider than a top lip thereof, a plurality of longitudinally spaced apertures in the base lip for securing the strip in place with appropriate stakes, the material of said strip being flexible and resilient to substantially retain its C-shaped cross-section, and including splicing means for connecting the ends of adjacent retainer strips together, said splicing means comprising an elongated sleeve segment having a C-shaped cross-section similar to that of the retainer strip and including longitudinal grooves along the outer edge of said sleeve segment for telescopingly receiving adjacent ends of said retainer strips therein.
Claim 6
Dependent Claim
61 words
A retainer strip as set forth in claim 3 wherein the elongated strips include apertures in the base lip thereof adjacent each end thereof and the splice means include a pair of spaced apertures in a base lip thereof alignable with the said strip apertures whereby said splice member and associated strip members may be anchored by a pair of stakes.
Claim 7
Dependent Claim
17 words
A retainer strip as set forth in claim 4 wherein the splice segment is a straight segment.
Claim 8
Dependent Claim
26 words
A retainer strip as set forth in claim 4 wherein the ends of the splice segment are formed at an angle to form an elbow joint.
Claim 9
Dependent Claim
14 words
A retainer strip as set forth in claim 6 wherein the joint is 90°.
Claim 10
Dependent Claim
21 words
A retainer strip as set forth in claim 6 wherein the joint is bent in the concave direction of the strip.
Claim 11
Dependent Claim
21 words
A retainer strip as set forth in claim 6 wherein the joint is bent in a convex direction of the strip.
Claim 12
Dependent Claim
18 words
A retainer strip as set forth in claim 1 and including stakes made of steel reinforcement bar segments.
