Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 297 words
A foldable lounge chair comprising an elongated horizontal platform having a front end and a rear end; front leg means pivotably connected to the platform front end for movement between an upstanding support position and a storage position folded toward the lower face of the platform; rear leg means pivotably connected to the platform rear end for movement between an upstanding support position and a storage position folded toward the lower face of the platform; a backrest pivotably connected to the platform near the platform rear end for movement between an upright position extending angularly upwardly from the platform and a storage position folded toward the upper face of the platform; a first transverse shaft located within the platform near the platform front end; an arm structure swingably mounted on said shaft for arcuate movement between a storage position extending within the platform plane and an operating position extending angularly upwardly from the platform; a hub structure affixed to the free end of said arm structure; a second shaft rotatably mounted in said hub structure; crank arms extending in opposite directions from the ends of said second shaft; a foot pedal carried on the free end of each crank arm; and a stop means for limiting arcuate movement of the arm structure to approximately one hundred ten degrees measured around the axis of the first transverse shaft, whereby the arm structure has an operating position wherein it extends upwardly and forwardly from the first transverse shaft; said stop means comprising a transverse bar (44) carried on the horizontal platform rearwardly from said first transverse shaft; said arm structure including an abutment element (46) extending away from the hub structure for engagement with the undersurface of said transverse bar when said arm structure has reached its operating position.
Claim 2
Dependent Claim 297 words
A foldable lounge chair comprising an elongated horizontal platform having a front end and a rear end; front leg means pivotably connected to the platform front end for movement between an upstanding support position and a storage position folded toward the lower face of the platform; rear leg means pivotably connected to the platform rear end for movement between an upstanding support position and a storage position folded toward the lower face of the platform; a backrest pivotably connected to the platform near the platform rear end for movement between an upright position extending angularly upwardly from the platform and a storage position folded toward the upper face of the platform; a first transverse shaft located within the platform near the platform front end; an arm structure swingably mounted on said shaft for arcuate movement between a storage position extending within the platform plane and an operating position extending angularly upwardly from the platform; a hub structure affixed to the free end of said arm structure; a second shaft rotatably mounted in said hub structure; crank arms extending in opposite directions from the ends of said second shaft; a foot pedal carried on the free end of each crank arm; and a stop means for limiting arcuate movement of the arm structure to approximately one hundred ten degrees measured around the axis of the first transverse shaft, whereby the arm structure has an operating position wherein it extends upwardly and forwardly from the first transverse shaft; said stop means comprising a transverse bar (44) carried on the horizontal platform rearwardly from said first transverse shaft; said arm structure including an abutment element (46) extending away from the hub structure for engagement with the undersurface of said transverse bar when said arm structure has reached its operating position.
Claim 3
Dependent Claim 73 words
The lounge chair of claim 1 wherein said first transverse shaft is a relatively long shaft extending substantially the entire transverse width of the horizontal platform, said second transverse shaft being a relatively short shaft located on the longitundinal centerline of the platform, whereby the foot pedals are located within the top plan dimensions of the horizontal platform so that a person reclining on the platform can exert foot pressure on the pedals.
Claim 4
Dependent Claim 66 words
The lounge chair of claim 1, and further comprising pad means extending along upper face areas of the platform and back rest; said pad means including a first pad extending along the back rest and the rear portion of the horizontal platform, and a second pad adapted to removably extend along the front portion of the platform when said arm structure is in its storage position.
