Lawn chair

Claim 2

A lawn chair having a modular frame construction comprising, a number of members forming a seat support, back and opposed sides, each of said members comprising a structure defined by a first elongated rod formed in a manner to define the periphery of the member, a plurality of spaced second rods fixed to and extending between opposed locations on the periphery of each member to provide a grid-like structure. Clamping means for fastening the members into a chair form, said clamping means comprising a pair of rigid blocks having abutting faces including at least a pair of substantially spaced grooves formed in each of said faces, each groove of one block being complimentary to a corresponding groove in the other block to define a channel for receiving adjacent portions of said first rod of adjacent members, means for securing said blocks together about said adjacent portions of said first rods of said members, a continuous cushion pad on said seat support for normally forming a cushioned seating surface and a cushioned back, said seat support including a bottom surface spaced above a chair support surface, said chair including at least a pair of substantially inverted U-shaped extendible members normally nested one within the other beneath said seat support and extendible relatively thereto along extremities forming the U-shape, said U-shape members forming an open channel extending toward the back substantially parallel to the sides and means for permitting said extendible members to be extracted from beneath the seat support while preventing the extendible members from being extended beyond the full front to rear extent, whereby said chair is convertible into a chaise lounge.

Claim 3

A lawn chair as recited in claim 1, wherein said cushion pad comprises a plurality of cushion sections arranged in series with adjacent sections hingedly joined together at one contiguous edge, a first of said sections being disposed upon said seat support, a second of said sections having an edge adjoining and contiguous with said first section and normally being folded upon said first section along the adjoining contiguous edge, a third of said sections having an edge adjoining and contiguous with said second section remote from said first section, said edge being one edge of adjacent surfaces of the second and third sections, the remainder of said adjacent surfaces diverging from each other so that the entire third section normally is folded into an upstanding disposition relatively to said second section and upon the first section to form said cushion back, said second and third sections being unfolded onto said extendible members when said members are fully extended.

Claim 4

A lawn chair as recited in claim 2, wherein said second section comprises a pair of sections hingedly joined together at a contiguous edge forming one edge of adjacent surfaces of said pair of sections, the remainder of said adjacent surfaces diverging from each other.

Claim 5

A lawn chair as recited in claim 3, wherein said third section comprises a pair of sections hingedly joined together at a contiguous edge forming one edge of adjacent surfaces of said pair of sections, the remainder of said adjacent surfaces diverging from each other.

Claim 6

A lawn chair convertible into a chaise lounge comprising, a frame including a seat support, back and opposed sides, said seat support including a bottom surface spaced above a chair support surface, said chair including at least a pair of substantially inverted U-shaped extendible members normally nested one within the other beneath said seat support and extendible relatively thereto along extemities forming the U-shape, said U-shaped members forming an open channel extending toward the back substantially parallel to the sides, means for permitting said extendible members to be extracted from beneath the seat support while preventing the extendible members from being extended beyond their full front to rear extent, said chair including a cushion pad positioned on said seat support for normally forming a cushioned seating surface and a cushioned back, said cushion pad comprising a plurality of cushion sections arranged in series with adjacent sections hingedly joined together at one contiguous edge, a first of said sections being disposed upon said seat support, a second of said sections having an edge adjoining and contiguous with said first section and normally being folded upon said first section along the adjoining contiguous edge, a third of said sections having an edge adjoining and contiguous with said second section remote from said first section, said edge being one edge of adjacent surfaces of the second and third sections, the remainder of said adjacent surfaces diverging from each other so that the entire third section normally is folded into an upstanding disposition relatively to said second section to form said cushion back, said second and third sections being unfolded onto said extendible members when said members are fully extended.

Claim 7

A lawn chair convertible into a chaise lounge comprising, a frame including a seat support, back and opposed sides, said seat support including a bottom surface spaced above a chair support surface, said chair including at least a pair of substantially inverted U-shaped extendible members normally nested one within the other beneath said seat support and extendible relatively thereto along extemities forming the U-shape, said U-shaped members forming an open channel extending toward the back substantially parallel to the sides, means for permitting said extendible members to be extracted from beneath the seat support while preventing the extendible members from being extended beyond their full front to rear extent, said chair including a cushion pad positioned on said seat support for normally forming a cushioned seating surface and a cushioned back, said cushion pad comprising a plurality of cushion sections arranged in series with adjacent sections hingedly joined together at one contiguous edge, a first of said sections being disposed upon said seat support, a second of said sections having an edge adjoining and contiguous with said first section and normally being folded upon said first section along the adjoining contiguous edge, a third of said sections having an edge adjoining and contiguous with said second section remote from said first section, said edge being one edge of adjacent surfaces of the second and third sections, the remainder of said adjacent surfaces diverging from each other so that the entire third section normally is folded into an upstanding disposition relatively to said second section to form said cushion back, said second and third sections being unfolded onto said extendible members when said members are fully extended.

Claim 8

A lawn chair as recited in claim 5, wherein said second section comprises a pair of sections hingedly joined together at a contiguous edge forming one edge of adjacent surfaces of said pair of sections, the remainder of said adjacent surfaces diverging from each other.

Claim 9

A lawn chair as recited in claim 6, wherein said third section comprises a pair of sections hingedly joined together at a contiguous edge forming one edge of adjacent surfaces of said pair of sections, the remainder of said adjacent surfaces diverging from each other.
