A stroller has a frame that is foldable or collapsible between an extended configuration and a collapsed configuration. A pair of locking devices are mounted on the frame to lock the frame in the extended configuration. The frame also has a handle or handle bar connected to portions of the frame connected to the locking devices. The stroller has a release mechanism mounted on a portion of the handle. The release mechanism has a moving member rotatably mounted to the handle portion. The moving member carries a rotation-to-linear motion transfer mechanism, which includes grooves. A pair of pins are movably mounted to the handle portion and engage the grooves. The pins are connected to the locking devices using wires. The grooves guides and moves the pins toward each other to release both locking devices when the moving member is rotated. A rotation lock prevents the moving member from releasing the locking devices. The rotation lock has a receiving member mounted on the handle portion and a reciprocating member mounted on the moving member. The reciprocating member engages the receiving member to prevent the moving member from rotating. The moving member and the reciprocating member are operable with a single hand to release the locking devices.

[ I claim:] [1.] A stroller having a frame that is foldable between an extended configuration and a collapsed configuration, and a pair of locking device mounted on the frame to lock the frame in the extended configuration, the frame having a handle connected to portions of the frame connected to the locking devices, the stroller further comprising:a release mechanism mounted on a portion of the handle, the release mechanism comprising:a moving member rotatably mounted to the handle portion, the moving member being rotatable between a locked position and an unlocked position;a motion transfer mechanism comprising a first opposing pair of helical grooves and a second opposing pair of helical grooves formed on the moving member, and a first slot and a second slot extending through the portion of the handle, the first and second slot being parallel and collinear;a pair of pulling members movably disposed relative to the handle portion and operably connected to the locking devices, the pulling members comprising a first pin guided in the first slot, the first pin having opposing ends extending outwardly from the handle portion, the opposing ends of the first pin being guided in the first opposing pair of helical grooves and a second pin guided in the second slot, the second pin having opposing ends extending outwardly from the handle portion, the opposing ends of the second pin being guided in the second opposing pair of helical grooves, wherein the first and second opposing pairs of helical grooves are configured to move the first and second pins in opposing directions, while the first and second slots confine the first and second pins linearly; anda rotation lock that prevents the moving member from releasing the locking devices, the rotation lock comprising a receiving member mounted on the handle portion and a reciprocating member mounted on the moving member, the reciprocating member engaging the receiving member to prevent the moving member from rotating,wherein the reciprocating member is movable toward and away from the receiving member and is biased toward the receiving member so that the reciprocating member automatically engages the receiving member when the moving member is rotated to the locked position, andwherein the first and second pairs of helical grooves are configured to engage and maintain the first and second pins held between the first and second opposing pairs of helical grooves without separately biasing the first and second pins.
