Abstract:
A novel folding and expanding hanger for narrow neck top wears is comprised of, including but not limited to, a spring, two solid wings, a pivot pin, a hook, and a member connecting the hook and pivot pin. The spring, coiled around at the center of the pivot pin, renders a repulsion force for thrusting the wings to the extended position. The two solid wings are firmly connected to the arms of the spring. The pivot pin is pivotably connected to one end of the two wings. The hook, which has distorted neck, is connected to a member, which has two hands anchored to the pivot pin at both sides of the spring. The hook may be connected directly to a spring, which has two extended wings of 5 to 20 cm long. The other ends of the two wings may be broader than the opposite ends for sustaining the shape of the top wears. The cross sectional shape of the wings is, including but not limited to, a circle, a hemi circle, a pizza slice shape, a triangle, a square, a pentagon, a hexagon and combination of those geometrical shapes. The novel structure of the hanger of this invention enables a user for easy putting of a hanger inside of the narrow neck of, including but not limited to, a round T-neck shirt, a men's dress shirts after engaging the buttons, a ladies blouse, and other top wears by folding the wings inwardly and push the hanger into the neck of the top wears. The hanger holds the shape of the top wears having narrow neck by simply releasing the wings.
