Abstract
Abstract A foldable seat device having diagonal side legs for support of a flexible sheet seat along its rearward and forward portions; and although legs extending from the rearward portion of the seat are conventionally continuous to their feet, the legs extending from the forward portion of the seat are of two discrete and non-connected portions. Of those legs, the adjacent ends of the lower rearward leg portion, and of the upper forward leg portion, are pivotally connected to the other legs at spaced points therealong; and those unconnected leg portions are pivotally movable independently of one another, permitting a seat-open condition of the seat even though the rear seat-feet may be then retracted to permit a support of the seat in a partially folded condition which permits a use of the seat while the device is leaning against a tree for user comfort. The pivotal connection involving of the lower rearward leg portions are movable along the legs extending from the rear of the seat, achieving, by an in-effect change of rear leg length, the advantage of optional seat-tilt change, for accommodation of variations of slope of the supporting ground, without a change of actual leg-length. A hook member permits convenient carry on the user's belt.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
285 words
A foldable seat device, comprising, in combination: a flexible seat; a first leg means providing diagonally extending support legs along both sides of the device, and rigidly interconnected by a rear transverse upper support bar, the support legs extending from a rearward upper end to a forward downward end providing a front support leg engagement of the ground; a second leg means providing diagonally extending supportive upper legs along both sides of the device, and rigidly interconnected by a forward transverse upper support bar, the supportive upper legs extending from a forward upper end to a lower end, there being pivot means, at each side of the device, pivotally connecting the lower end of each respective one of the said supportive upper legs to a generally central portion of the respective support leg of the first leg means; and the said second leg means also providing diagonally extending supportive lower legs, along both sides of the device, the said supportive lower legs at their lower ends providing rear support leg engagement of the ground; there being a supportive connection connecting the upper portion of the said supportive lower legs of the said second leg means to the respective support legs of the said first leg means, said supportive connection being at a location spaced from the said pivot means; the respective supportive upper legs and the supportive lower legs of the second leg means being non-co-linear, and with the second leg means at each side of the device receiving force from the supportive upper legs of the second leg means by transmission of such force through a portion of the first leg means which is between the said pivot means and the said supportive connection.
Claim 2
Dependent Claim
285 words
A foldable seat device, comprising, in combination: a flexible seat; a first leg means providing diagonally extending support legs along both sides of the device, and rigidly interconnected by a rear transverse upper support bar, the support legs extending from a rearward upper end to a forward downward end providing a front support leg engagement of the ground; a second leg means providing diagonally extending supportive upper legs along both sides of the device, and rigidly interconnected by a forward transverse upper support bar, the supportive upper legs extending from a forward upper end to a lower end, there being pivot means, at each side of the device, pivotally connecting the lower end of each respective one of the said supportive upper legs to a generally central portion of the respective support leg of the first leg means; and the said second leg means also providing diagonally extending supportive lower legs, along both sides of the device, the said supportive lower legs at their lower ends providing rear support leg engagement of the ground; there being a supportive connection connecting the upper portion of the said supportive lower legs of the said second leg means to the respective support legs of the said first leg means, said supportive connection being at a location spaced from the said pivot means; the respective supportive upper legs and the supportive lower legs of the second leg means being non-co-linear, and with the second leg means at each side of the device receiving force from the supportive upper legs of the second leg means by transmission of such force through a portion of the first leg means which is between the said pivot means and the said supportive connection.
Claim 3
Dependent Claim
57 words
The invention as set forth in claim 1, in a combination in which the supportive connection of the upper ends of the said supportive lower legs to the first leg means is provided by another pivotal connection means, including abutment means limiting the rearward pivotability of the supportive lower legs with respect to the first leg means.
Claim 4
Dependent Claim
136 words
The invention as set forth in claim 1, in a combination in which the supportive connection of the upper ends of the said supportive lower legs to the first leg means is provided by connection means movable with respect to the support legs of the first leg means, which provides an option of were, along each support leg of the first leg means, is the connection thereto of the respective supportive lower leg, thereby providing an optional variation in the comparative distance between the lower end of the supportive lower legs of the second leg means to the rear transverse upper bar, and the lower end of the support legs of the first leg means to the forward transverse upper bar, without any change of length of the supportive lower leg of the second leg means.
Claim 5
Dependent Claim
138 words
The invention as set forth in claim 2, in a combination in which the supportive connection of the upper ends of the said supportive lower legs to the first leg means is provided by connection means movable with respect to the support legs of the first leg means, which provides an option of where, along each support leg of the of the first leg means, is the connection thereto of the respective supportive lower leg, thereby providing an optional variation in the comparative distance between the lower end of the supportive lower legs of the second leg means to the rear transverse upper bar, and the lower end of the support legs of the first leg means to the forward transverse upper bar, without any change of length of the supportive lower legs of the second leg means.
Claim 6
Dependent Claim
71 words
The invention as set forth in claim 3, in a combination in which the movable connection means includes a plurality of detent means, and it also includes a support bracket supportingly interconnecting the respective lower supportive leg and the respective support leg of the first leg means, the detent means including abutment lugs carried by the first leg means, and opening means in the bracket for optionally receiving the abutment lugs.
