Patent ID: 6910709

Claim:
A bi-directional safety lock structure for strollers folding single-handedly to control a release mechanism of joint sets of a stroller frame, comprising: an element anchor dock fastened to the stroller frame having a first sliding flute and a second sliding flute; a depressing element slidable reciprocally in the first sliding flute to drive the release mechanism, the depressing element having an outer protrusive section extending upwardly; wherein the depressing element slides in the first sliding flute when subject to an external force to drive the release mechanism and actuate the joint sets of the stroller frame to activate stroller folding operation; and a sliding element two-way slidable reciprocally in the second sliding flute having a bucking section corresponding to the outer protrusive section of the depressing element; wherein the sliding element is at a static condition when located on a middle portion of the second sliding flute such that the bucking section presses the outer protrusive section to prevent the depressing element from sliding in the first sliding flute, and when the sliding element is moved leftwards or rightwards to release the outer protrusive section thereby the depressing element is movable under an external depressing force to actuate the release mechanism such that the joint sets are driven to activate the stroller folding operations, the sliding element being movable both leftwards and rightwards to release the outer protrusive section.
