ABSTRACT:
A hinge for use in serving carts to secure a pivotable door to the housing of the cart has a first pintle mounted in lugs provided in one vertical marginal portion of a sidewall forming part of the housing of a cart, a second pintle mounted in lugs extending from one vertical marginal portion of the door, and leaves which have holes or bores for both pintles and alternate with the lugs. At least one of the pintles is non-rotatably connected to the respective lugs or to the leaves. If the second pintle is non-rotatably connected to the leaves, it is pivotable with the leaves between a closed position and a position in whichis it coplanar with the sidewall carrying the first pintle, thereupon with the leaves to a position at right angles to and outwardly adjacent the sidewall, and thereafter to a fully open position which it reaches by pivoting about the axis of the second pintle and relative to the leaves. The sidewall and the door shield the leaves and the pintles in each position of the door.
