Abstract

Abstract A building structure which utilizes logs or timbers of readily available dimensions. A plurality of timbers are horizontally disposed in parallel, vertically spaced relationship to form wall sections. Intermediate each pair of adjacent horizontal timbers there is a pair of convex panels of flexible synthetic resinous material, symmetrically disposed about the vertical axis. Upper and lower edges of each panel are inserted into oblique panel-receiving slots provided in the upper and lower surfaces of each horizontal timber. The panels are preferably inserted after assembly of the timbers and support no direct load. Insulating material is placed between each pair of panels. The panels may be inserted during or after assembly of overlapping end surfaces of timbers of end-adjacent vertical walls. If desired, insulating material may be inserted in the confined zone between panels and successive logs. Preferably, substantially light-permeable panel members are used and substantially light-permeable insulating means is used between panel members to permit natural lighting of the interior of the building structure during daylight hours.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 164 words
A log cabin structure comprising load-bearing logs or timbers and essentially load-free panels disposed therebetween forming end-adjacent walls having end portions of said timbers interdigitated in direct load bearing relationship one on the other, free of a common vertical loadbearing member, each end-adjacent wall having plural horizontal timbers of generally uniform cross section maintained in spaced apart parallel relationship by interdigitation of said end portions, said timbers having a pair of longitudinal grooves in the upper and lower faces thereof, said grooves being in parallel spaced apart relationship over the length of said timbers, and said grooves having a preselected depth and width chosen so that each groove snugly accommodates one longitudinal edge of each of a pair of essentially no-load-bearing elongated laminar plastic panels to form a confined zone bounded by upper and lower timber surfaces, the inner surfaces of said panels and end surfaces of timbers of another wall, and fastening means to fasten said timbers rigidly relative to one and another.
Claim 2
Dependent Claim 164 words
A log cabin structure comprising load-bearing logs or timbers and essentially load-free panels disposed therebetween forming end-adjacent walls having end portions of said timbers interdigitated in direct load bearing relationship one on the other, free of a common vertical loadbearing member, each end-adjacent wall having plural horizontal timbers of generally uniform cross section maintained in spaced apart parallel relationship by interdigitation of said end portions, said timbers having a pair of longitudinal grooves in the upper and lower faces thereof, said grooves being in parallel spaced apart relationship over the length of said timbers, and said grooves having a preselected depth and width chosen so that each groove snugly accommodates one longitudinal edge of each of a pair of essentially no-load-bearing elongated laminar plastic panels to form a confined zone bounded by upper and lower timber surfaces, the inner surfaces of said panels and end surfaces of timbers of another wall, and fastening means to fasten said timbers rigidly relative to one and another.
Claim 3
Dependent Claim 22 words
The log cabin structure of claim 1 wherein each said end portion is fastened to abutting upper and lower interdigitated timbers only.
Claim 4
Dependent Claim 15 words
The log cabin structure of claim 1 wherein said fastening means is an adhesive means.
Claim 5
Dependent Claim 33 words
The log cabin structure of claim 1 including a base timber and a top timber having only one longitudinal face provided with a pair of parallel spaced apart longitudinal grooves in said face.
Claim 6
Dependent Claim 17 words
The log cabin structure of claim 1 wherein said confined zone has thermal insulating material disposed therewithin.
Claim 7
Dependent Claim 22 words
The log cabin structure according to claim 5 wherein said insulating material is in batt form adhered to the said panels, respectively.
Claim 8
Dependent Claim 164 words
A log cabin structure comprising load-bearing logs or timbers and essentially load-free panels disposed therebetween forming end-adjacent walls having end portions of said timbers interdigitated in direct load bearing relationship one on the other, free of a common vertical load-bearing member, each end-adjacent wall having plural horizontal timbers of generally uniform cross section maintained in spaced apart parallel relationship by interdigitation of said end portions, said timbers having a pair of longitudinal grooves in the upper and lower faces thereof, said grooves being in parallel spaced apart relationship over the length of said timbers, and said grooves having a preselected depth and width chosen so that each groove snugly accommodates on longitudinal edge of each of a pair of elongated laminar light transmitting plastic panels to form a confined zone bounded by upper and lower timber surfaces, the inner surfaces of said panels and end surfaces of timbers of another wall, and fastening means to fasten said timbers rigidly relative to one and another.
Claim 9
Dependent Claim 164 words
A log cabin structure comprising load-bearing logs or timbers and essentially load-free panels disposed therebetween forming end-adjacent walls having end portions of said timbers interdigitated in direct load bearing relationship one on the other, free of a common vertical load-bearing member, each end-adjacent wall having plural horizontal timbers of generally uniform cross section maintained in spaced apart parallel relationship by interdigitation of said end portions, said timbers having a pair of longitudinal grooves in the upper and lower faces thereof, said grooves being in parallel spaced apart relationship over the length of said timbers, and said grooves having a preselected depth and width chosen so that each groove snugly accommodates on longitudinal edge of each of a pair of elongated laminar light transmitting plastic panels to form a confined zone bounded by upper and lower timber surfaces, the inner surfaces of said panels and end surfaces of timbers of another wall, and fastening means to fasten said timbers rigidly relative to one and another.
Claim 10
Dependent Claim 18 words
The log cabin structure of claim 6 including sealing means to seal all exterior joints of said structure.
Claim 11
Dependent Claim 34 words
The log cabin structure of claim 7 wherein said grooves are disposed at an angle from the vertical to permit insertion of upper and lower edges of said panels after assembly of said timbers.
Claim 12
Dependent Claim 20 words
The log cabin structure of claim 9 wherein at least one panel is flexed to assume a convex exterior surface.
Claim 13
Dependent Claim 24 words
The log cabin structure of claim 10 wherein the outer panel of said pair of panels is flexed to assume a convex interior surface.
