    摘要： Two cam operated pawls are pivotally attached to a first hinge plate each having a detent on the end opposite the pivotal connection to alternately engage staggered notches on opposite edges of a locking arm attached to a second hinge plate causing one detent to be armed to lock within a notch whenever the other detent is released from a locked position whereby the hinge plates can be locked with respect to pivotal movement relative to each other and released only for incremental movements of the total range of movement at any one time.

    摘要： An improved chair for combined office and rest use is disclosed which includes a support member carried by a support leg and having its front end portion extended obliquely upward, a chair seat pivotably mounted at its front edge to the front end portion of the support member, a rotary shaft rotatably mounted on the chair seat transversely thereacross and having an operation handle fixedly secured thereto. A cam is fixedly secured to the rotary shaft and has a hook-shaped slot opening for slidable cooperation relative to a fixed pin transversely traversing the slot and mounted on the support member, and resilient means are interposed between the chair seat and its support member. Normally the pin is engaged within the hook tip portion of the cam slot opening to lock the chair seat in a substantially horizontal position. A rotational operation of the handle is accompanied with a disengagement of the pin from the hook tip portion of the cam slot, and thereby the chair seat becomes rockable about the pivot at the front end portion of the support member aided by slight shifting of the occupant''s weight.
