Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 180 words
Portable blind apparatus comprising a pair of vertical end frames, a seat forming body member rigidly secured between the frames to support them in upright positions and connected thereto for seat adjustment to selected heights, an open top container detachably secured at its ends to the end frames under the body member when the latter is disposed in an elevated position, said container being adapted to contain a heating element and having passages for the upward movement of heated air upwardly from the container and about the seat of the body member, said passages being formed, in part, by upper edges of the container walls and adjacent peripheral edges of the seat forming body member, and means for selectively controlling the relative amounts oF air passing upwardly around the front and rear edges of the seat, which means includes an upper wall section of the container that is pivoted adjacent its lower edge so that its upper edge may be adjusted with respect to one edge of said body member to thereby control the size of the air passage therebetween.
Claim 2
Dependent Claim 180 words
Portable blind apparatus comprising a pair of vertical end frames, a seat forming body member rigidly secured between the frames to support them in upright positions and connected thereto for seat adjustment to selected heights, an open top container detachably secured at its ends to the end frames under the body member when the latter is disposed in an elevated position, said container being adapted to contain a heating element and having passages for the upward movement of heated air upwardly from the container and about the seat of the body member, said passages being formed, in part, by upper edges of the container walls and adjacent peripheral edges of the seat forming body member, and means for selectively controlling the relative amounts oF air passing upwardly around the front and rear edges of the seat, which means includes an upper wall section of the container that is pivoted adjacent its lower edge so that its upper edge may be adjusted with respect to one edge of said body member to thereby control the size of the air passage therebetween.
Claim 3
Dependent Claim 55 words
The structure specified in claim 1 in which upper sections of opposite walls of the container are pivotally mounted so that upper edges of said sections may be independently secured in adjusted positions with respect to adjacent edges of said body member to selectively control the air flows to and around said body member edges.
