  • Patent number: 4226350
    Abstract: A keyholder adapted for use as an addition to a garment has a body formed from a backing plate with a retainer plate attached at an acute angle to form a V-shaped trough. Key loop openings in the retainer plate have a trapezoidal slot opening at its longer base to the free edge of the retainer plate, and the short base opens to a circular aperture. The backing plate is provided with a cavity or hole positioned to cooperate with the circular aperture in retaining a spherical key loop therebetween. The sphere is relatively large, such as one-quarter inch or more, so that it provides a caming surface that allows removal or insertion of the sphere in the keyholder body with moderate forces.
