  • Patent number: 4326687
    Abstract: A plurality leg stand, e.g., a tripod, with a novel one piece connector head that connects the legs at the top ends thereof. The one piece connector head, which is molded from an elastomer, has a number of hinge lines molded in a lower face which equal the number of stand legs, thereby permitting the stand's legs to move between collapsed parallel storage position and erected pyramid stand position. The head also includes a pad on an upper face that is sized to cooperate with the hinge lines molded in the lower face to provide certain definition for those hinge lines. The pad is of a thickness that the pad's top surface is elevated above the legs to receive a horizontal display bar at any rotational position thereon when the stand is erected.

  • Patent number: 4319512
    Abstract: A capotasto having a force plate of a length sufficient to overlie two adjacent frets on a stringed instrument's fingerboard. The capotasto's leading edge portion is adapted to press the instrument's strings against a leading fret of two adjacent frets, and the capotasto's trailing edge portion is adapted to press the instrument's strings against the trailing fret of the two adjacent frets. The capotasto's force plate may be flexible in order to generally conform to the curvature or linearity of the instrument's frets when the capotasto is clamped in place on the adjacent frets.
