Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 258 words
A building comprising a permanent main structure having interconnected walls and a roof, a secondary roof structure pivotally connected to a least a portion of one wall of the main structure for pivotal movement between a raised position in which it extends outwardly to form the roof of a verandah, porch, carport or the like and a substantially vertical lowered position in which said secondary roof structure substantially covers said portion of the wall, means for biasing said secondary roof structure to its raised outwardly extending position, a pair of support posts adapted to be pivotal to the ground independently of and spaced from said main structure for movement from a raised position wherein each of said posts is adpated to support a respective side of said secondary roof structure and a lowered position wherein said posts are substantially flush with the ground and extend from their pivotal supports toward said one wall portion, locking means for detachably connecting the upper ends of said posts to said secondary roof structure when said posts and said secondary roof structure are in their raised positions, and retaining means for detachably retaining said secondary roof structure to said posts when said posts and said secondary roof structure are in their lowered positions with the lower end of the seocndary roof structure disposed outwardly of the lower end of the one wall portion for providing a storage area between the secondary structure and said one wall portion when said secondary roof structure is in its lowered position to contain and protect articles.
Claim 2
Dependent Claim 258 words
A building comprising a permanent main structure having interconnected walls and a roof, a secondary roof structure pivotally connected to a least a portion of one wall of the main structure for pivotal movement between a raised position in which it extends outwardly to form the roof of a verandah, porch, carport or the like and a substantially vertical lowered position in which said secondary roof structure substantially covers said portion of the wall, means for biasing said secondary roof structure to its raised outwardly extending position, a pair of support posts adapted to be pivotal to the ground independently of and spaced from said main structure for movement from a raised position wherein each of said posts is adpated to support a respective side of said secondary roof structure and a lowered position wherein said posts are substantially flush with the ground and extend from their pivotal supports toward said one wall portion, locking means for detachably connecting the upper ends of said posts to said secondary roof structure when said posts and said secondary roof structure are in their raised positions, and retaining means for detachably retaining said secondary roof structure to said posts when said posts and said secondary roof structure are in their lowered positions with the lower end of the seocndary roof structure disposed outwardly of the lower end of the one wall portion for providing a storage area between the secondary structure and said one wall portion when said secondary roof structure is in its lowered position to contain and protect articles.
Claim 3
Dependent Claim 25 words
A building as claimed in claim 1 wherein the secondary roof structure is biased to the outwardly raised extending position by means of torsion rods.
Claim 4
Dependent Claim 50 words
A building as claimed in claim 1 wherein the secondary roof structure is mounted intermediate its ends on supporting posts spaced apart from the one wall portion of the building so that it acts as a balance beam for biasing said secondary wall structure to its raised outwardly extending positon.
Claim 5
Dependent Claim 30 words
A building as claimed in claim 1 wherein the inner end of the secondary roof structure is weighted for biasing said secondary wall structure to its raised outwardly extending position.
Claim 6
Dependent Claim 14 words
A building as claimed in claim 1 wherein the locking means comprises removable pins.
