Abstract
Abstract An insulated, substantially rectangular building block is disclosed. The block contains two spaced, outer supportive parts which are interlockably connected with each other and which extend along the length of the block; and a curvilinear inner insulating material is present in the space between the supportive parts. Each of the outer supportive parts has a configuration which differs from that of the other such part. The insulating material is wedge-shaped, and it fits into a space between said supportive parts which is defined by walls which extend inwardly from the top of the building block to its bottom.

Claim 1
Independent Claim
305 words
An insulated building block of substantially rectangular shape comprised of a first spaced outer supportive part, a second spaced outer supportive part, curvilinear means for laterally interlockably connecting said first spaced outer supportive part and said second space outer supportive part, and a substantially curvilinear, integral inner insulating portion, wherein: (a) each of said first spaced outer supportive part and said second spaced outer supportive part extends along the length of said building block, is comprised of an inner surface defining a side of the space between said parts, and has a configuration which differs from the configuration of the other of said spaced outer supportive parts; (b) said space between said first and second spaced outer supportive parts is substantially curvilinear in cross section as viewed from the top of said building block; (c) said space between said first and second spaced outer supportive parts is wedge-shaped and is defined by walls which extend inwardly from the top of said building block to the bottom of said building block; (d) said insulating portion is positioned within an substantially fills the space between said first spaced outer supportive part and said second spaced outer supportive part, thereby forming said susbstantially rectangular building block; (e) said building block is comprised of two opposite planar sidewalls, two opposite planar ends, a planar top, and a planar bottom; (f) each of said planar sidewalls is parallel to the other of said planar sidewalls, each of said planar ends, is parallel to the other of said planar ends, and said planar top is parallel to said planar bottom; (g) said insulating portion is substantially centered between and extends beyond each of said two planar ends; and (h) said insulating portion extends beyond at least one of said planar top surface and said planar bottom surface of said building block.
