Abstract
Abstract A simulated log for construction and indoor or outdoor decorative use such as a divider panel or as a log beam comprised of at least two semi-circular imitation log siding sections comprising an outer covering with a simulated grain wood containing an insulated filler. An upright support has the central rear portion of the covering secured along its diameter. A pair of thicker uprights are secured to the first upright on the edge of log and have the outer ends of the covering secured thereto. The supports form an integral part of the log.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
An insulating simulated semi-log unit comprising an outer generally semi-cylindrical covering sheet integrally united along its length at opposed ends to a pair of upright supports, both of said supports joined to a flat panel section, with the interior of said unit, in which the upright supports are each spaced by joined spacer means from said flat panel section so as to form a lower and an upper open recess along the length of the unit at opposed ends of the unit, said recesses located such that when two such units are mounted in vertical array, with the flat panel section of one unit extending as a vertical extension of the panel section of the second unit, the lower recess of the upper unit is aligned with the upper recess of the lower unit so that a shaped spline unit may be fitted in said aligned units to latch the two sections together when said spline is fitted in said unit by fastening means.
Claim 2
Dependent Claim
164 words
An insulating simulated semi-log unit comprising an outer generally semi-cylindrical covering sheet integrally united along its length at opposed ends to a pair of upright supports, both of said supports joined to a flat panel section, with the interior of said unit, in which the upright supports are each spaced by joined spacer means from said flat panel section so as to form a lower and an upper open recess along the length of the unit at opposed ends of the unit, said recesses located such that when two such units are mounted in vertical array, with the flat panel section of one unit extending as a vertical extension of the panel section of the second unit, the lower recess of the upper unit is aligned with the upper recess of the lower unit so that a shaped spline unit may be fitted in said aligned units to latch the two sections together when said spline is fitted in said unit by fastening means.
Claim 3
Dependent Claim
38 words
The invention as recited in claim 1, in which two such units are mounted back-to-back to form a cylindrical shaped log unit by joining together of the exterior surfaces of the flat panel section of each semi-log unit.
Claim 4
Dependent Claim
54 words
The invention as recited in claim 1, together with a spline unit of the general length of a semi-log unit, said spline unit of a size and shape to snugly fit into the common interior of two aligned recesses of two semi-log units that are aligned in vertical array as recited in claim 1.
Claim 5
Dependent Claim
21 words
The combination as recited in claim 3, in which the spline unit is formed of a block of polyurethane foamed material.
Claim 6
Dependent Claim
29 words
The invention as recited in claim 1, in which a plurality of semi-log units are fastened in vertical array to a common panel to form a length of siding.
