  • Hat comprising a variable circumference aperture
    Patent number: 11304468
    Abstract: A hat includes a first and second overlapping panel in the rear of the body and an elastic band. The overlapping panels each comprise an arcuate edge. When overlapped, the arcuate edges define an aperture. An elastic band attaches to the arcuate edges and transitions from the first arcuate edge to the second arcuate edge in a looping manner. When a wearer pulls her hair through the aperture, the aperture increases in size. Once the wearer's hair is pulled through the aperture, the aperture decreases in size and provides a secure fit around the wearer's hair. The elastic loop supports the long hair upwards in a manner that prevents the hat from riding up or the hair from falling onto a rear brim.

  • Iron-type golf club head with flex structure
    Patent number: 11298596
    Abstract: Embodiments of an iron type golf club head with a flex structure, a face reinforcing structure, and a variable face thickness to increase face element bending while improving club head durability are described herein. The club head comprises a face element for striking a golf ball. The face element is formed integrally with the flex structure. The flex structure comprises a curved profile (e.g. S-shape or sinusoidal) that functions like a spring to support the face element during golf ball impacts. The face reinforcing structure comprises a looped rib that provides support around a center of the face element. The variable face thickness includes thickened and thinned regions to provide further face element bending or support. The combination of the flex structure, the face reinforcing structure, and the variable face thickness provides increased face element bending while improving club head durability.
