Abstract
Abstract A curbing module having interconnected sections as provided by body members interconnectable to provide a row of sections of curbing. The body members are preferably cast, and have embedded within each body member a generally U-shaped retainer member extending longitudinally and outwardly of each of the body members. Each end of the retainer member of one body member co-operates with a recess of the adjacent body member, providing, also with an associated stake-pin, the functions of both hold-down and alignment, providing and assuring a continuously attractive straightness and orderliness of the curbing as composed by a plurality of such sections.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A curbing module means comprising: at least three body members each providing a section of curbing, and all three being substantially identical in respects herein mentioned, the body members being provided each with a generally U-shaped retainer member having a bight portion extending outwardly from a first end of the respective body member and extending longitudinally of the respective body member, and having legs with transversely-spaced ends which extend outwardly of a second end of the respective body member, each of the body members also provided with transversely-spaced recess means on an end thereof, receivable respectively of the outwardly-extending leg-ends of the said retainer member, at least one of the sets of retainer member leg-ends and its associated recess means of an adjacent body member providing by their co-operating engagement an alignment means for alignment of adjacent body members.
Claim 2
Dependent Claim
139 words
A curbing module means comprising: at least three body members each providing a section of curbing, and all three being substantially identical in respects herein mentioned, the body members being provided each with a generally U-shaped retainer member having a bight portion extending outwardly from a first end of the respective body member and extending longitudinally of the respective body member, and having legs with transversely-spaced ends which extend outwardly of a second end of the respective body member, each of the body members also provided with transversely-spaced recess means on an end thereof, receivable respectively of the outwardly-extending leg-ends of the said retainer member, at least one of the sets of retainer member leg-ends and its associated recess means of an adjacent body member providing by their co-operating engagement an alignment means for alignment of adjacent body members.
Claim 3
Dependent Claim
113 words
The invention as set forth in claim 1, in a combination in which the portion of each body member, which is provided with the recess means which receives the bight portion of the retainer member, is also provided with a second recess intersecting the first-named recess means and of a generally vertical orientation to intersect the said bight portion, an associated stake pin being provided to be driven through the said second recess, into the said first-named recess means which receives said bight portion and through the bight portion of the retainer member of the adjacent body member, and into the associated ground upon which the curbing module means is to be placed.
Claim 4
Dependent Claim
68 words
The invention as set forth in claim 1, in a combination in which the end of each body member which in the assembly of the three body members is adjacent the end of the retainer member remote from the bight portion thereof, is provided with its recess means to be a sufficiently close fit with the said end of the retainer member that it provides the said alignment.
Claim 5
Dependent Claim
68 words
The invention as set forth in claim 2, in a combination in which the end of each body member which in the assembly of the three body members is adjacent the end of the retainer member remote from the bight portion thereof, is provided with its recess means to be a sufficiently close fit with the said end of the retainer member that it provides the said alignment.
Claim 6
Dependent Claim
55 words
The invention as set forth in claim 1, in a combination in which the leg-ends of the retainer member are provided to be at a large spacing, but the retainer member is provided to have its bight portion of smaller size, as considered transversely of the body member, than is the spacing of the leg-ends.
Claim 7
Dependent Claim
55 words
The invention as set forth in claim 2, in a combination in which the leg-ends of the retainer member are provided to be at a large spacing, but the retainer member is provided to have its bight portion of smaller size, as considered transversely of the body member, than is the spacing of the leg-ends.
Claim 8
Dependent Claim
55 words
The invention as set forth in claim 3, in a combination in which the leg-ends of the retainer member are provided to be at a large spacing, but the retainer member is provided to have its bight portion of smaller size, as considered transversely of the body member, than is the spacing of the leg-ends.
Claim 9
Dependent Claim
55 words
The invention as set forth in claim 4, in a combination in which the leg-ends of the retainer member are provided to be at a large spacing, but the retainer member is provided to have its bight portion o smaller size, as considered transversely of the body member, than is the spacing of the leg-ends.
