摘要： A collapsible stroller includes a stroller frame, a folding lock mechanism, a lateral lock mechanism, and a trigger mechanism. The stroller frame includes a right upper side frame member pivotally connected with a right lower side frame member and a left upper side frame member pivotally connected with a left lower side frame member. The folding lock mechanism is capable of a locked state and an unlocked state. The lateral lock mechanism is capable of a locked operating state and an unlocked operating state. The trigger mechanism is on the stroller frame, and actuation of the trigger mechanism moves the folding lock mechanism from the locked state to the unlocked state and moves the lateral lock mechanism from the locked operating state to the unlocked operating state.

摘要： In accordance with some aspects of the present disclosure, there is provided a foldable stroller frame comprising a first side frame member, a second side frame member, a middle frame member, and a sliding mechanism configured to slide along the middle frame member. First and second cross frame members may connect the sliding mechanism to the first and second side frame members. In some examples, the first and second cross frame members may comprise a curved portion proximate the connection with the side frame members. The sliding member may comprise an upper portion and a lower portion. In some examples, spring-biased tongues disposed in the lower portion may bias the upper portion. In some examples third and fourth cross frame members may connect the first side frame member and the second side frame member to a foot pedal that may be disposed on the middle frame member.

摘要： A collapsible stroller includes a stroller frame, at least one hinge mechanism, a wheel, and a swivel mechanism. The stroller frame is moveable between a deployed position and a collapsed position. The hinge mechanism allows for movement of the stroller frame between the collapsed position and the deployed position. The swivel mechanism connects the wheel to the stroller frame. The swivel mechanism includes a vertical axle, a cam follower, and a cam. The vertical axle connects with the wheel and is rotatable with respect to the stroller frame about a vertical axis. The cam follower is fixed to the vertical axle. The cam includes a sloped cam surface at least partially surrounding the vertical axle. The sloped cam surface contacts the cam follower to move the cam follower along the sloped cam surface, which results in rotation of the vertical axle about the vertical axis.

摘要： A lightweight collapsible stroller is provided. The stroller includes: a frame including a first portion movable relative to a second portion; a drive mechanism coupled to the frame, which moves the first portion relative to the second portion, thereby transitioning the frame between an open position and a closed position; and a latch mounted to the frame. The latch is positioned to engage at least a portion of the first portion or the second portion when the frame is in its open position to restrict the first portion from moving relative to the second portion. Upon actuation, the drive mechanism causes the latch to release, such that the first portion of the frame moves relative to the second portion of the frame, thereby allowing the frame to transition to the closed position.

摘要： An example stroller disclosed herein includes a joint carried by a frame. The joint includes a first housing, a second housing, and a third housing disposed between the first housing and the second housing. The first, second, and third housings respectively include first, second, and third openings. The stroller includes a lock including a lever and a bar. The bar is to simultaneously mater with the first, second, and third openings of the first, second, and third housings when the lever is in a first position to prevent rotation of the first housing and the second housing relative to the third housing, and to disengage from the first, second, and third openings of the first, second, and third housings when the lever is in a second position to enable the first housing and the second housing to rotate relative to the third housing to fold the stroller.
