Abstract
Abstract A modular form is disclosed for enabling an individual unskilled in bricklaying techniques to install professional looking patios, walkways, or to resurface walls and the like. The forms comprise tray-like modules, containing a network of grids which create brick-shaped voids arranged in commonly used brick patterns. After placing the modules on a suitable surface, bricks are inserted into the voids and a suitable grouting material such as sand and portland cement or masonry cement is applied between the bricks. The modules insure correct brick pattern spacing and a professional looking final product and permit considerable time savings when compared to conventional methods. The grids are preferably arranged to form a "basketweave" pattern for ground use and a "running bond" pattern for wall use, but other patterns are also disclosed. The invention also provides interlocking means for the modules so that uniformity of the pattern is retained in the creation of various sized patios, walkways or brick walls.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
127 words
A modular form for laying blocks in a desired pattern comprising: (a) a sheet of semi-rigid material including a raised peripheral rim and a plurality of dividers, said rim including two pairs or opposed parallel sides and square corners, said rim and said dividers being generally U shaped in cross-section and each being of substantially the same height, said height being less than the height of the blocks to be laid, (b) a plurality of block-shaped sections formed on said sheet by said rim and said dividers, said sections being arranged in said desired pattern, and (c) means on the rim of said sheet for permitting interlocking of a plurality of said forms to one another and for permitting continuation of said desired pattern between adjoining forms.
Claim 2
Dependent Claim
127 words
A modular form for laying blocks in a desired pattern comprising: (a) a sheet of semi-rigid material including a raised peripheral rim and a plurality of dividers, said rim including two pairs or opposed parallel sides and square corners, said rim and said dividers being generally U shaped in cross-section and each being of substantially the same height, said height being less than the height of the blocks to be laid, (b) a plurality of block-shaped sections formed on said sheet by said rim and said dividers, said sections being arranged in said desired pattern, and (c) means on the rim of said sheet for permitting interlocking of a plurality of said forms to one another and for permitting continuation of said desired pattern between adjoining forms.
Claim 3
Dependent Claim
32 words
The invention set forth in claim 1 further including rectangular blocks disposed in each of said sections, said blocks being higher than said rim and dividers and grouting material between said blocks.
Claim 4
Dependent Claim
39 words
The invention set forth in claim 1 wherein the width of the rim on two contiguous sides of said form is less than the width of said dividers and the width of the rim of said other two sides.
Claim 5
Dependent Claim
20 words
The invention set forth in claim 1 wherein said form has at least one aperture within each of said sections.
Claim 6
Dependent Claim
45 words
The invention set forth in claim 4 further including rectangular blocks disposed in each of said sections, said blocks being higher than said rim and dividers and grouting material intermediate said sheet and the adjoining surface of said blocks and grouting material between said blocks.
Claim 7
Dependent Claim
33 words
The invention set forth in claim 1 wherein said interlocking means comprise cut-out portions of said rim means ro permit the rim of one unit to overlap the rim of an adjoining unit.
Claim 8
Dependent Claim
39 words
The invention set forth in claim 6 wherein said pattern is a running bond pattern and wherein said interlocking means additionally includes cut-out portions of said rim means to accomodate said dividing means and block overlap between adjoining forms.
Claim 9
Dependent Claim
69 words
The invention set forth in claim 6 wherein said pattern is a basketweave pattern and said dividers define at least eight rectangular block shaped sections on said sheet the major lengths of at least four of said sections being in a direction perpendicular to the major length of the remaining sections and wherein said interlocking means includes additional cut-out portions of said rim means to accomodate said dividing means.
Claim 10
Dependent Claim
79 words
The invention set forth in claim 8 wherein said form is substantially square and wherein said dividers comprise: two dividers joining the mid-points of opposing sides of said square to divide said square into four smaller squares, and four additional dividers, one located in each of said smaller squares and joining the mid-point of one set of opposing sides thereof, the direction of two of said additional dividers being perpendicular to the direction of the remaining two additional dividers.
Claim 11
Dependent Claim
24 words
The invention of claim 9 wherein the direction of two of said additional dividers is the same for diagonal ones of said smaller squares.
