Abstract

An articulated handle for a floor-treating apparatus in which a lower forked portion of the handle is pivotally hinged onto a base member. A yoke joins the ends of the lower forked portion remote from the base member and is provided with a channel in which is received a moveable latching bar and a depressable latch button which moves the bar against a spring. The handle also includes an upper forked portion having a handle at one end. The other end of the upper portion terminates in a pair of identical ears formed at the ends of the tines of the upper fork and each of these ears is received in the yoke in operative relation with the bar. Each ear has an inclined surface which engages the bar locking the lower and upper forked portions in extended relation and when the bar is depressed the upper and lower portions of the handle fold into a collapsed position or juxtaposed relation.

Claims

1. Apparatus including a base member and a handle member connected with said base member, the improvement comprising in the handle member a lower fork connected with said base member, a yoke joining the ends of said lower fork remote from said base member, an upper fork pivotally connected with said yoke at one end, a handle connected with the ends of said upper fork remote from said yoke, and means for releasably locking said forks in extended position;

said releasable locking means including a channel in said yoke, a bar movably mounted in said channel, a pair of ears connected with said upper fork and coupled with said yoke, said ears having a curved surface extending into said channel and engaging said bar, an inclined surface coextensive with the said curved surface of said ears, said inclined surface and the adjacent surface of said channel defining a pair of wedge-shaped recesses for receiving said bar when said forks in their extending position; and

means connected with said bar for moving said bar out of said recesses.

2. Apparatus according to claim 1 wherein said bar has a wedge-shaped cross section.

3. Apparatus according to claim 2 wherein each of said forks converge toward said yoke.
