Abstract
Abstract A standardized concrete form includes a series of rectangular slots spaced along the sides thereof and which extend virtually the entire length thereof which, along with mounting holes, permits the standardized hardware pins to join adjacent concrete forms at virtually an infinitely variable step height therebetween. The standardized mounting holes are formed in cloverleaf shape in order to accommodate and facilitate the insertion of hardware pins when adjacent forms are slightly misaligned.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
177 words
In a concrete form for constructing a wall, said form being adapted for arrangement in a first plurality as a first wall so that their sides are aligned in adjacent manner to form a first surface and a second plurality as a second wall to form a second surface, said first and second surfaces being spaced apart to thereby define the faces of said constructed wall, and a plurality of holes spaced at substantially regular intervals in the sides of said forms so that hardware may be inserted therethrough to secure adjacent forms together, the improvement comprising a plurality of substantially rectangular slots spaced along at least one side of said form, at least one of said slots being located between each pair of adjacent holes, and between the end of said side and a mounting hole, said slots having their longest dimension running substantially parallel to the sides of said form so that said hardward may be inserted through said slots at any point therealong to thereby secure adjacent forms which are offset from each other.
Claim 2
Dependent Claim
177 words
In a concrete form for constructing a wall, said form being adapted for arrangement in a first plurality as a first wall so that their sides are aligned in adjacent manner to form a first surface and a second plurality as a second wall to form a second surface, said first and second surfaces being spaced apart to thereby define the faces of said constructed wall, and a plurality of holes spaced at substantially regular intervals in the sides of said forms so that hardware may be inserted therethrough to secure adjacent forms together, the improvement comprising a plurality of substantially rectangular slots spaced along at least one side of said form, at least one of said slots being located between each pair of adjacent holes, and between the end of said side and a mounting hole, said slots having their longest dimension running substantially parallel to the sides of said form so that said hardward may be inserted through said slots at any point therealong to thereby secure adjacent forms which are offset from each other.
Claim 3
Dependent Claim
31 words
The form of claim 1 wherein each of said slots extends for substantially the entirety of the distance between adjacent holes, or between a hole and the end of the side.
Claim 4
Dependent Claim
37 words
The form of claim 2 wherein said slots have substantially the same width as said holes so that said hardware may be readily inserted through a hole in one form and a slot in its adjacent form.
Claim 5
Dependent Claim
30 words
The form of claim 3 wherein at least some of said holes are cloverleaf shaped to thereby facilitate the insertion therethrough of said hardward between forms which are minimally offset.
Claim 6
Dependent Claim
17 words
The form of claim 4 wherein said slots are spaced along all four sides of said four.
Claim 7
Dependent Claim
38 words
The form of claim 5 further comprising a plurality of ties for extending between said walls, said ties having openings therein for matching and lining up with said holes and slots to thereby be secured by said hardware.
Claim 8
Dependent Claim
119 words
In a concrete form for erection into two opposing walls, with the sides of adjacent forms being secured together, for pouring a vertical wall of concrete therebetween, the improvement comprising means in the sides of said forms for securing together the sides of adjacent forms which are offset an irregularly variable distance from each other, said securing means comprising a plurality of substantially rectangular slots, said slots having their long dimension substantially parallel to the sides of said forms, and a plurality of holes, adjacent holes being separated by at least one of said slots, and at least one of said slots being situated adjacent each end of said side, and hardware for insertion through said holes and slots.
Claim 9
Dependent Claim
119 words
In a concrete form for erection into two opposing walls, with the sides of adjacent forms being secured together, for pouring a vertical wall of concrete therebetween, the improvement comprising means in the sides of said forms for securing together the sides of adjacent forms which are offset an irregularly variable distance from each other, said securing means comprising a plurality of substantially rectangular slots, said slots having their long dimension substantially parallel to the sides of said forms, and a plurality of holes, adjacent holes being separated by at least one of said slots, and at least one of said slots being situated adjacent each end of said side, and hardware for insertion through said holes and slots.
Claim 10
Dependent Claim
21 words
The form of claim 7 wherein said holes are substantially cloverleaf shaped to thereby facilitate the insertion therethrough of said hardware.
Claim 11
Dependent Claim
87 words
In a concrete form for erection into two opposing walls, with the sides of adjacent forms being secured together, for pouring a vertical wall of concrete therebetween, the improvement comprising a plurality of cloverleaf shaped holes spaced along the sides of said forms, a plurality of substantially rectangularly shaped slots with at least one of said slots being located between adjacent holes, and between the end of each side and a hole, said holes and slots facilitating the insertion therethrough of hardware between slightly offset adjacent forms.
Claim 12
Dependent Claim
87 words
In a concrete form for erection into two opposing walls, with the sides of adjacent forms being secured together, for pouring a vertical wall of concrete therebetween, the improvement comprising a plurality of cloverleaf shaped holes spaced along the sides of said forms, a plurality of substantially rectangularly shaped slots with at least one of said slots being located between adjacent holes, and between the end of each side and a hole, said holes and slots facilitating the insertion therethrough of hardware between slightly offset adjacent forms.
Claim 13
Dependent Claim
31 words
The form of claim 9 wherein each of said slots extends for substantially the entirety of the distance between adjacent holes, or between a hole and the end of the side.
Claim 14
Dependent Claim
