Adjustable floor support for needlecraft and art frames

Claim 2

An adjustable floor support for needlecraft and art frames comprising: a pair of floor engaging feet; a pair of legs extending vertically from said feet and each including a knee joint for swinging an upper portion of each leg in a plane thereof to an inclined angle relative to a lower vertical portion of said leg; a longitudinally expandable and contractible cross member extending between said legs to laterally support said legs on said feet; variable mouth clamp means at an upper end of each leg for receiving and releasably gripping needlecraft and art frames of different thickness; and selectively operable means for releasably locking said knee joints in different positions to regulate the angulation between said upper and lower portions of said legs; and said feet each including floor engaging portions extending forward of said legs in the direction of swinging of said upper leg portions to balance and support said legs and frame against tipping upon a swinging of said upper leg portions to an inclined position.

Claim 3

An adjustable floor support for needlecraft and art frames comprising: a floor engaging base; a leg extending vertically from said base and including a knee joint for swinging an upper portion of the leg in a plane thereof to an inclined angle relative to a lower vertical portion of said leg; a variable mouth clamp means at an upper end of said leg for receiving and releasably gripping needlecraft and art frames of different thicknesses and shapes, said clamp means including first and second jaw means defining an open mouth, means for releasably connecting said first and second jaw means to move toward and away from each other to receive and clamp an edge portion of said frame therebetween, said first jaw means being connected to and supported by said pivot means for turning thereon, and said second jaw means being reversible on said first jaw means to change the maximum opening of said mouth defined by said first and second jaw means to accept and clamp a thicker frame portion therebetween; and pivot means for connecting said clamp means at said upper end of said leg, and for supporting said clamp means for turning on a horizontal axis to adjust the angle of inclination of a frame relative to said leg.

Claim 4

An adjustable floor support for needlecraft and art frames comprising: a floor engaging base; a leg extending vertically from said base and including a knee joint for swinging an upper portion of the leg in a plane thereof to an inclined angle relative to a lower vertical portion of said leg; a variable mouth clamp means at an upper end of said leg for receiving and releasably gripping needlecraft and art frames of different thicknesses and shapes, said clamp means including first and second jaw means defining an open mouth, means for releasably connecting said first and second jaw means to move toward and away from each other to receive and clamp an edge portion of said frame therebetween, said first jaw means being connected to and supported by said pivot means for turning thereon, and said second jaw means being reversible on said first jaw means to change the maximum opening of said mouth defined by said first and second jaw means to accept and clamp a thicker frame portion therebetween; and pivot means for connecting said clamp means at said upper end of said leg, and for supporting said clamp means for turning on a horizontal axis to adjust the angle of inclination of a frame relative to said leg.

Claim 5

The adjustable floor support of claim 2 wherein: each of said first and second jaw means includes adjacent base portions with jaw portions projecting forwardly therefrom to define one of said open mouths; the base portion of said first jaw means including an opening for receiving said pivot means to support said first jaw means for turning on said pivot means; and the jaw portion of said second jaw means including a step like projection facing said jaw portion of an associated first jaw means to define a small open mouth relative to a larger open mouth defined by said second jaw means when reversed on said first jaw means.

Claim 6

An adjustable floor support for needlecraft and art frames comprising: a pair of floor engaging feet; a pair of legs extending vertically from said feet and each including a knee joint for swinging an upper portion of each leg in a plane thereof to an inclined angle relative to a lower vertical portion of said leg; a longitudinally expandable and contractible cross member extending between said legs to laterally support said legs on said feet; variable mouth clamp means at an upper end of each leg for receiving and releasably gripping needlecraft and art frames of different thickness; and pivot means for connecting said clamp means at said upper ends of said legs with said mouths facing each other to receive opposing edge portions of and clamp a frame therebetween, and for supporting said clamp means for turning on a common horizontal axis to adjust the angle of inclination of said frame relative to said legs.

Claim 7

An adjustable floor support for needlecraft and art frames comprising: a pair of floor engaging feet; a pair of legs extending vertically from said feet and each including a knee joint for swinging an upper portion of each leg in a plane thereof to an inclined angle relative to a lower vertical portion of said leg; a longitudinally expandable and contractible cross member extending between said legs to laterally support said legs on said feet; variable mouth clamp means at an upper end of each leg for receiving and releasably gripping needlecraft and art frames of different thickness; and pivot means for connecting said clamp means at said upper ends of said legs with said mouths facing each other to receive opposing edge portions of and clamp a frame therebetween, and for supporting said clamp means for turning on a common horizontal axis to adjust the angle of inclination of said frame relative to said legs.

Claim 8

The adjustable floor support of claim 4 further including manually adjustable means for selectively locking said pivot means against turning of said clamp means on said pivot means.

Claim 9

The adjustable floor support of claim 4 wherein said clamp means each include: first and second jaw means defining said open mouths; means for releasably connecting said first and second jaw means to move toward and away from each other to receive and clamp edge portions of said frame therebetween; said first jaw means being connected to and supported by said pivot means for turning thereon; and said second jaw means being reversible on said first jaw means to change the maximum opening of said mouth defined by said first and second jaw means to accept and clamp thicker frame portions therebetween.

Claim 10

The adjustable floor support of claim 6 wherein: each of said first and second jaw means includes adjacent base portions with jaw portions projecting forwardly therefrom to define one of said open mouths; the base portion of each first jaw means including an opening for receiving said pivot means to support said first jaw means for turning on said pivot means; and the jaw portion of each second jaw means including a step like projection facing said jaw portion of an associated first jaw means to define a small open mouth relative to a larger open mouth defined by said second jaw means when reversed on said first jaw means.
