The present disclosure relates to a double stroller, with a frame thereof including three side supports and two transverse supports. Each two adjacent side supports are connected to each other via one transverse support. Each transverse support includes at least one connecting rod assembly, and each connecting rod assembly includes an outer connecting rod fixedly connected with the side support on a left or right side and an inner connecting rod fixedly connected with the side support in the middle. The outer connecting rod is connected to the inner connecting rod in a horizontally rotatable manner. The outer connecting rods and inner connecting rods connected in a horizontally rotatable manner to enable the side supports on two sides to close together as the outer connecting, rods are turned transversely and folded, and thus, after being folded, the space occupied by the double stroller in the left-right direction is lessened.

A wheeled carrier device such as a baby stroller, golf cart, child carrier, or general carrier or cargo cart, comprising a bottom frame with at least two rear wheels and at least one front wheel, and may include a movably mounted upper carrier frame with a selectively removable, adjustable and/or reversible carrying element which may include child seating, with a unique wheel folding mechanism that interconnects all the wheels, so that simple movement of a wheel folding grasp synchronously moves all the wheels between the operative, rolling position and their stowed fold flat positions parallel with the bottom frame, with the wheel folding mechanism operable independently of collapsing movement of an optional upper carrier frame which also folds flat and parallel with the bottom frame.

A stroller includes a frame, a sliding member and a seat fixing base. The sliding member is rotatably connected to the frame. The seat fixing base is rotatably connected to the frame and slidably connected to the sliding member. When the frame is folded, the frame drives the seat fixing base to slide with respect to the sliding member.

Systems and methods for a stroller with a one-hand collapsing mechanism in accordance with embodiments of the inventions are disclosed. In a first aspect of the present disclosure, a folding stroller includes a collapsible frame, at least one wheel in a front part of the collapsible frame, at least one wheel in a rear part of the collapsible frame, at least one folding hinge coupled to the collapsible frame, a seating area having a seat portion and a back portion, and a release handle in the seat portion of the seating area, the release handle configured to be actuated with a one hand action, wherein the release handle is coupled to the at least one folding hinge, wherein the release handle is accessible through the seating area, and wherein actuating the handle causes the frame to transform from a deployed position to a collapsed position.

A transportation device includes a handle a rear leg, a front leg, a seat, a fixing member, a first seat linkage member and a second seat linkage member. The front leg is pivotally connected to the rear leg. The seat is pivotally connected to the front leg. The fixing member is disposed at a rear side of the seat and connected to an end of the handle. The first seat linkage member is pivotally connected to the seat and the fixing member. The second seat linkage member is pivotally connected to the seat and the rear leg. When the handle, the rear leg and the front leg are folded with respect to each other, the fixing member and the rear leg drive the rear side of the seat to rotate toward a direction opposite to the ground by the first seat linkage member and the second seat linkage member respectively.

A folding frame which serves as basis for a stroller base to allow the interconnection of a child safety seat thereto, while allowing the installation of the child safety seat to a vehicle seat without requiring the disconnection of the safety seat from the folding frame. The folding frame extends from a folded configuration to an unfolded configuration for use as a stroller with or without the use of the child safety seat.

A stroller having a folding frame which serves as basis for a stroller which can be used in a seat configuration for the transportation of a child, and which can be alternatively used in a cart configuration wherein the seat-bottom and seat-back are hingedly interconnected and configured to fold out into a cart for transporting goods such as groceries.

A folding mechanism for a stroller including a cover, a front leg connector pivoted to the cover, a rear leg connector pivoted to the front leg connector, and a front guard member pivoted to the front leg connector is disclosed. A pair of connection arms extends from the front guard member. The folding mechanism includes a rotatable member pivoted to the cover and detachably connected to the connection arm. An abutting portion protrudes from the rotatable member. When the rear leg connector is unfolding, the rear leg connector abuts against the abutting portion and drives the front guard member rotating relative to the cover to an unfolded position. When the rear leg connector is folding, the rear leg connector is detached from the abutting portion to release the front guard member to a folded position.

A foldable stroller frame comprising a lower frame. The lower frame has a front frame section and a rear frame section which are pivotal relative to one another. The lower frame also has a hinge device linking the front frame section to the rear frame section. The hinge device has at least two parts pivotally coupled together and rotatable about a movable axis of rotation between a deployed state and a collapsed state. The hinge device also has a handle arranged along the axis of rotation for grasping by a user to enable the hinge device to be operated.
