  • Patent number: 4730757
    Abstract: A first and second arm pivotally connected together at first ends for pivoting from an extended to a retracted position. Upwardly extending extensions are connected to the first ends and are connected to a resilient loop for resiliently holding the arms in the extended position but allowing the arms to be retracted downwardly. A supporting hook is connected to a pivot and provides a stop limiting the extended motion of the arms and also prevents the loop from moving past dead center of the pivot means.

  • Patent number: 4673116
    Abstract: A clothes hanger having a first and second member. The first member has a supporting hook, a circular hinge section and a first supporting arm. The second member has a second supporting arm and a pivoting axle extending through the circular section for allowing the arms to move downwardly towards each other and a stop engagable with the top of the first supporting arm for limiting the extent of upward movement of the arms. A spring between the first and second members yieldably urges the first and second arms upwardly and away from each other to cause the stop to engage the first arm for supporting a garment from the arms, but allows the garment to be pulled downwardly and off of the hanger by causing movement of the arms downwardly and towards each other.
