The application discloses a frame of double-person baby carriage and a frame folding mechanism thereof The frame folding mechanism comprises an upper link, a lower link, a middle upright rod, two upper supporting rods, two lower supporting rods and two foot frames. The upper link and the lower link are spaced apart in a vertical direction; the middle upright rod is vertically connected between the upper link and the lower link; first ends of the two upper supporting rods are pivotally connected to both ends of the upper link; first ends of the two lower supporting rods are pivotally connected to both ends of the lower link; the foot frames are arranged in a vertical direction, top ends of the foot frames are pivotally connected to second ends of the upper supporting rods, bottom ends of the foot frames are pivotally connected to second ends of the lower supporting rods.

A device for transporting children. The transportation device includes a base and sidewalls extending therefrom, forming an interior volume. Wheels extend from a lower side of the base and a foldable seat is affixed to at least one sidewall. A pair of doors are hingedly attached to opposing sidewalls, which allow a child ingress and egress from the transportation device. The folding seat allows the transportation device to include an increased capacity to hold objects when not in use by the child.

A wheel locking axle assembly is provided to secure a wheel to a hub of a child conveyance device. An embodiment of the wheel locking assembly includes a hub including a retention feature and a wheel assembly. The wheel assembly includes a wheel, a sleeve coupled to the wheel, a spindle that is slidable within a channel of the sleeve, and at least one detent captured by the sleeve and the spindle. The spindle can be moved between a first longitudinal position with respect to the sleeve in which a portion of each detent extends radially outwardly through a respective through-hole in the sleeve to lockingly engage the retention feature of the hub and a second longitudinal position with respect to the sleeve in which each detent does not extend radially outwardly through the through-hole and disengages the retention feature of the hub.

A folding perambulator has a wheeled foldable frame 1 with front frame members 10 which may be folded toward rear frame members 5 when a seating member 2 is removed from the frame 1. A handle 7 is also arranged to be foldable downwardly toward the rear wheels 3. A locking mechanism 6 is provided to permit the frame and handle to be folded. The handle includes a rotatable member 25 which, in one direction of rotation, is arranged to adjust the length of the handle by permitting telescoping of tubular members 26, 27, and in an opposite direction of rotation to cause the locking mechanism, which includes a dog clutch 80, to be disengaged to permit the frame and handle to be folded to a closed position.

A child stroller system having a frame-assembly including a frame, a plurality of wheels, and a push-handle. The seat-assembly includes a seat and a seat-mounting-bracket, a storage bag support-assembly including a storage-bag and a bag-mount-member. The frame-assembly, the seat-assembly, and the storage bag support assembly in functional combination allow the seat to swing-rotate in relation to the frame and the bag-mount-member providing a resting platform for the storage-bag. The frame-assembly supports the seat-assembly and the storage bag support-assembly such that a child and stored items are able to be transported simultaneously. The child stroller system further includes a kinesthetic toy attached to the seat to provide amusement for said child.

A foldable stroller frame includes a connection unit interconnecting two opposite foldable side frame units, each of which includes a front leg and a handle rod connected pivotally to each other, and a rear leg connected pivotally to the handle rod. The connection unit includes four bottom rods each having a first end connected pivotally to a connecting seat, and a second end connected pivotally to a respective one of the front and rear legs of the side frame units. When the connecting seat is pulled upwardly from a lower used position, the second ends of the bottom rods move radially toward each other, whereby the side frame units are folded and move toward each other.
