Adjustable brim for a hat

1. A brim for use with a hat, wherein the hat is configured to sit atop a head of a user, the brim comprising:

an approximately circular shaped sheath defining a channel and including a curved attachment edge;

a tightening device positioned within the channel of the sheath; and

a brim body attached to the sheath, the brim body including:

an inner edge;

an outer edge opposite the inner edge;

an inner surface and an outer surface opposite the inner surface spanning the inner edge to the outer edge; and

wherein the brim body is constructed of a material having sufficient rigidity to maintain a set manipulated shape;

wherein the brim body is shaped such that, if the brim body were to be laid flat along a planar surface, each of the inner edge and the outer edge would exhibit a curved shape different from the curved attachment edge; and

wherein, when the sheath is positioned around the hat when worn by the user, attachment between the inner edge of the brim body and the attachment edge of the sheath supports the outer edge of the brim body in position below the attachment edge, wherein a portion of the outer edge of the brim body is configured to be maintained in a lofted position spaced above a neck and ears of the user, wherein the maintaining of the lofted position is functionally due to said sufficient rigidity of the brim body's material.

2. The brim of claim 1 , wherein, if the brim body were to be laid flat along the planar surface, a majority of the inner edge and a majority of the outer edge each comprise a respective parabolic curve portion.

3. The brim of claim 2 , wherein the lofted position is a first position, and wherein the outer edge of the brim body is configured to be manipulated between the lofted first position and an upward second position.

4. The brim of claim 3 , wherein a first portion of the outer edge of the brim body is configured to be manipulated into the lofted first position and a second portion of the outer edge of the brim body is configured to be manipulated into the upward second position.

5. The brim of claim 2 , wherein the inner edge and the outer edge of the brim body meet at outer points of the brim body.

6. The brim of claim 5 , wherein the brim body has a crescent shape.

7. The brim of claim 2 , wherein a connection of the parabolic curve portion of the inner edge to the circular sheath assists the portion of the outer edge of the brim body to be maintained in the lofted position spaced above the neck and ears of the user, when the brim and the hat are being worn by the user.

8. The brim of claim 1 , wherein a radius of curvature of the rounded shape of the inner edge varies between outer points of the brim body.

9. The brim of claim 1 , wherein the curved attachment edge of the sheath defines a plane P and the inner and outer surfaces of the brim body form an angle with the plane P of between 55 and 65 degrees.

10. The brim of claim 1 , wherein the sheath includes a front sheath surface and a rear sheath surface that define the channel, wherein the front sheath surface and the rear sheath surface are connected along an upper edge and a lower edge, and wherein the lower edge comprises the attachment edge.

11. A method for using a brim with a hat, wherein the hat is configured to sit atop a head of a user above a neck and ears of the user, the method comprising:

providing the brim, the brim comprising:

an approximately circular shaped sheath defining a channel and including a curved attachment edge;

a tightening device positioned within the channel of the sheath; and

a brim body attached to the sheath, the brim body including:

an inner edge;

an outer edge opposite the inner edge; and

an inner surface and an outer surface opposite the inner surface spanning the inner edge to the outer edge;

wherein the brim body is constructed of a material having sufficient rigidity to maintain a set manipulated shape;

wherein the brim body is shaped such that, if the brim body were to be laid flat along a planar surface, the inner edge would exhibit a curved shape different from the curved attachment edge; and

positioning the sheath of the brim about a base of the hat so that the outer edge of the brim body is below the attachment edge, wherein a portion of the outer edge of the brim body is configured to be maintained in a lofted position spaced above the neck and ears of the user, when the hat sits on the user's head, and wherein the maintaining of the lofted position is functionally due to said sufficient rigidity of the brim body's material.

12. The method of claim 11 , wherein the curved attachment edge of the sheath defines a plane, and wherein the inner and outer surfaces of the brim body form an angle with the plane of between 55 and 65 degrees.

13. The method of claim 11 , wherein the positioning step comprises positioning the sheath of the brim about the base of the hat so that the outer edge of the brim body is in a downward position below the attachment edge and spaced from above the neck and ears of the user, and further comprising a step of manipulating a further portion of the outer edge of the brim body into an upward position.
