Folding bimini

1. A foldable bimini that is rigid and bi-directionally stable in an erected orientation on a boat, the bimini comprising:

a rigid arch-shaped frame comprising a first leg mountable to a first side of the boat, a second leg mountable to a second side of the boat, a cross-piece connected to upper ends of the first and second legs for spanning across the boat, and a disengageable bimini mount; and

a foldable bimini support, comprising a first rigid arch member pivotally mounted to the rigid arch shaped frame and at least one rigid leg pivotally mounted to the first arch member and releasably connectable to the disengageable bimini mount of the rigid arch-shaped frame,

wherein the bimini support may be positioned in an erected orientation by pivoting the first rigid arch member away from the rigid arch-shaped frame and pivoting the leg to engage a lower end of the leg with the disengageable bimini mount of the rigid arch-shaped frame to connect the lower end of the leg to the rigid arch-shaped frame, with the resulting structure of the bimini support as connected to the rigid arch shaped frame being rigid and bi-directionally stable so as to avoid relative movement of the first rigid arch member relative to the rigid arch-shaped frame.

2. The foldable bimini of claim 1 , wherein the foldable bimini support further comprises a second rigid arch member pivotally connected to the first rigid arch member.

3. The foldable bimini of claim 1 , further including a flexible sun cover, the sun cover comprising a flexible material dimensioned to conform to and span between the rigid arch-shaped frame and the foldable bimini support when the foldable bimini support is in the erected orientation, and the cover may be rolled around the first rigid arch member for storage when the foldable bimini support is in the folded orientation.

4. A foldable bimini that is rigid and bi-directionally stable in an erected orientation on a boat, the bimini comprising:

a rigid arch-shaped frame comprising a first leg mountable to a first side of the boat a second leg mountable to a second side of the boat a cross-piece connected to upper ends of the first and second legs for spanning across the boat, a first disengageable bimini mount located on the first leg, and a second disengageable bimini mount located on the second leg; and

a foldable bimini support, comprising a first rigid arch member pivotally mounted to the rigid arch shaped frame, a second rigid arch member pivotally connected to the first rigid arch member, and a pair of rigid legs pivotally mounted to opposite sides of the first arch member and each being releasably connectable to one of the disengageable bimini mounts of the rigid arch-shaped frame,

wherein the bimini support may be positioned in an erected orientation by pivoting the first rigid arch member away from the rigid arch-shaped frame and pivoting each of the rigid legs to engage a lower end of each of the legs with one of the disengageable bimini mounts of the rigid arch-shaped frame to connect the lower ends of the legs to the rigid arch-shaped frame, with the resulting structure of the bimini support as connected to the rigid arch shaped frame being rigid and bi-directionally stable so as to avoid relative movement of the first rigid arch member relative to the rigid arch-shaped frame.

5. The foldable bimini of claim 4 , further including a flexible sun cover, comprising a flexible material dimensioned to conform to and span between the rigid arch-shaped frame and the foldable bimini support when the foldable bimini support is in the erected orientation, and the cover may be rolled around the first and second rigid arch members for storage when the foldable bimini support is in the folded orientation.
