Abstract
Abstract A substantially cylindrical-shaped log having two planar surfaces substantially perpendicular to each other formed on the surface of the log with the remaining surface being generally cylindrical to provide structural support which is superior to that of a building log unit with only a cylindrical surface. The building log provides the child an option of interior and exterior play surfaces and further selectively provides a traditional exterior of round logs as well as a more modern exterior of a substantially planar facade, as well as providing a log structure which has excellent stability and structural strength when used as a base log, as well as a log placed in a intermediate position in a structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
A building log unit, a plurality of which may be used to form a structure, the building log unit comprising: a generally elongated, substantially cylindrical-shaped member shaped to resemble a log, said log having first and second planar surfaces arranged perpendicular to one another, a diagonally aligned surface positioned between adjacent longitudinal edges of said planar surfaces; a cylindrical surface extending between remaining longitudinal edges of said planar surfaces; and said log unit having a first set of notches provided near opposite ends thereof, said notches being shaped to interlock with similarly shaped notches formed in other similarly shaped logs.
Claim 2
Dependent Claim
100 words
A building log unit, a plurality of which may be used to form a structure, the building log unit comprising: a generally elongated, substantially cylindrical-shaped member shaped to resemble a log, said log having first and second planar surfaces arranged perpendicular to one another, a diagonally aligned surface positioned between adjacent longitudinal edges of said planar surfaces; a cylindrical surface extending between remaining longitudinal edges of said planar surfaces; and said log unit having a first set of notches provided near opposite ends thereof, said notches being shaped to interlock with similarly shaped notches formed in other similarly shaped logs.
Claim 3
Dependent Claim
38 words
A building unit as claimed in claim 1 wherein one of the first planar surfaces forms a base member of a structure built so as to provide increased structural stability to the structure fabricated from the log units.
Claim 4
Dependent Claim
29 words
A building unit as claimed in claim 1 wherein the log unit is provided with a second set of notches arranged diametrically opposed to the first set of notches.
Claim 5
Dependent Claim
16 words
A building unit as claimed in claim 1 wherein said first set of notches are square-shaped.
Claim 6
Dependent Claim
22 words
A building unit as claimed in claim 1 wherein said first set of notches are provided in one of said planar surfaces.
Claim 7
Dependent Claim
28 words
A building unit as claimed in claim 1 wherein said first set of notches are provided in said cylindrical surface, diametrically opposed to one of the planar surfaces.
Claim 8
Dependent Claim
47 words
A building unit as claimed in claim 1 wherein said first set of notches provided in one of said planar surfaces have a width which is substantially equal to a width of the log measured along a diameter which is perpendicular to one of said planar surfaces.
Claim 9
Dependent Claim
98 words
A building log unit, a plurality of which may be used to form a structure, the building log unit comprising: a generally elongated, substantially cylindrical-shaped member shaped to resemble a log, said log having first and second planar surfaces arranged perpendicular to one another, a diagonally aligned surface positioned between adjacent longitudinal edges of a planar surfaces; said cylindrical surface extending between the remaining longitudinal edges of said planar surfaces; said log having at least a pair of diametrically opposed of notches, said notches being shaped to interlock with similarly shaped notches formed in other similarly shaped logs.
Claim 10
Dependent Claim
98 words
A building log unit, a plurality of which may be used to form a structure, the building log unit comprising: a generally elongated, substantially cylindrical-shaped member shaped to resemble a log, said log having first and second planar surfaces arranged perpendicular to one another, a diagonally aligned surface positioned between adjacent longitudinal edges of a planar surfaces; said cylindrical surface extending between the remaining longitudinal edges of said planar surfaces; said log having at least a pair of diametrically opposed of notches, said notches being shaped to interlock with similarly shaped notches formed in other similarly shaped logs.
Claim 11
Dependent Claim
29 words
A building unit as claimed in claim 1 wherein said diagonally aligned surface is a curved surface having a radius of curvature substantially the same as said cylindrical surface.
