A rear wheel interlock folding mechanism of a golf bag cart is revealed. An upper frame is fixed on an upper-frame connecting rod connected to a lower frame. A rear-wheel connecting rod is fixed on the lower frame and behind the upper-frame connecting rod. A rear-wheel set is set on each end of the rear-wheel connecting rod. The rear-wheel set includes a fixing base fixed on the rear-wheel connecting rod, a bending base pivotally connected to the fixing base, a rear wheel pivotally disposed on the outer end of the bending base, a rotating seat fixed on the upper-frame connecting rod and a link between the bending base and the rotating seat. Thereby the bending base is also moved to drive the rear wheel moving close to the lower frame when the upper frame is folded toward the lower frame. Thus the golf bag cart is folded conveniently.

A baby stroller for transporting an infant at speeds faster than normal walking is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.

A baby stroller includes a frame having front and rear wheel supports, a seat rod, a push rod and a support rod. The front and rear wheel supports form a first rotating joint. The push rod includes upper and lower push rods, the lower push rod is connected to the first rotating joint. The lower push rod and the upper push rod form a second rotating joint. The support rod is rotatably connected with the upper push rod. The support rod is rotatably connected with the rear wheel support. The seat rod is rotatably connected with the front wheel support. The seat rod is rotatably connected with the support rod. Rotating the upper push rod around the second rotating joint drives the lower push rod, the support rod, the front wheel support, the rear wheel support and the seat rod to fold the stroller.

A carrier adjusting mechanism is applied to a stroller including a stroller frame and a carrier and includes a base, a locking structure, a locking device, and a release actuator. The base is connected to the stroller frame. The locking structure is connected to the carrier and pivoted to the base. The locking device is disposed between the base and the locking structure. The locking device includes a first engaging structure, a second engaging structure, and a locking member. The locking member is engaged with the first engaging structure at a first position or the second engaging structure at the second position. The release actuator is disposed on the stroller and connected to the locking device for disengaging the locking member from the first engaging structure or the second engaging structure, to allow the locking structure to move between the first position and the second position together with the carrier.

Disclosed are foldable carts, and connecting and stabilizing mechanisms of foldable carts. A foldable cart includes first and second frames pivotally connected to each other by a connecting and stabilizing mechanism. The connecting and stabilizing mechanism allows the first and second frames to rotate toward or away from each other, and thus allow the cart to fold and unfold. The connecting and stabilizing mechanism includes positioning pins and corresponding slots to receive the positioning pins, and thus prevent the cart from folding unintentionally.

The disclosure provides a fixing device, and a passenger device and a carrying device using fixing device. The fixing device is used to detachably fix the carrying device to the passenger device, and includes an engaging mechanism and an engaging seat. Among them, after the engaging mechanism is engaged into the engaging seat, the engaging mechanism and the engaging seat are able to be locked or unlocked, and an unlocked state holding mechanism is disposed in the engaging mechanism, and after the engaging mechanism and the engaging seat are unlocked, the unlocked state holding mechanism is able to hold the engaging mechanism and the engaging seat in an unlocked state. The fixing device according to the disclosure can fix the carrying device to the passenger device more safely.

Foldable strollers and related methods are disclosed herein. An example frame for use with a stroller includes a first leg, a second leg, a first joint to couple the first leg and the second leg, a handle arm, and a second joint to couple the handle arm and the first leg. The second joint includes a first portion having a pocket and a second portion including a lock slidably disposed in the second portion. The lock is to be removably coupled to the pocket. The handle arm is to rotate relative to the first leg via the second joint when the lock is removed from the pocket. The rotation of the handle via the second joint is to enable the second leg to rotate relative to the first leg via the first joint to fold the frame.

The present invention discloses a collapsible cart with a base panel and basket support frame. Two hinge mounts extend from the base frame and a hinge pin extends from each hinge mount. The basket support frame has two support beams that are slidably and rotatable mounted on the hinge pins. Each hinge mount forms a receiving space that can receive and block rotation of each support beam. A cable made of flexible material mounts between the two support beams. When a downward or upward force is exerted on the cable, each end of the cable pulls the support beams towards each other along the longitudinal axis of the hinge pin causing the support beams to move into a position which is clear of the receiving space and allows rotation around the hinge pins towards the base panel and into a collapsed position.

The present invention provides a baby stroller frame linked folding device. A linked folding joint is provided on the upper end of a rear leg frame and is pivotally connected with a front leg frame and a handlebar frame. The handlebar frame comprises a lower handlebar frame that is pivotally connected to the linked folding joint, a handlebar folding clutch joint configured on the upper end of the lower handlebar frame, and an upper handlebar frame pivotally connected to the handlebar folding clutch joint. On the inner side of the linked folding joint, a seatback clutch joint is configured, for installation of a seatback frame, and a slide base is configured, which can slide along the rear leg frame, and both sides of the top end of the slide base are respectively and pivotally connected with a connecting rod, each respectively and pivotally connected to the front leg frame and the lower handlebar frame; when the upper handlebar frame turns and folds onto the lower handlebar frame, it will firstly drive the releasing push block inside the seatback clutch joint so that the seatback frame will fall down, then, the lower sliding block pushes the hook to release the slide base, so that the slide base will slide downward, causing the two connecting rods to pull the front leg frame and the handlebar frame and fold them onto the rear leg frame. Thus, the baby stroller frame can be folded all at once.

A foldable stroller comprises a folding mechanism to assist in folding of the stroller. Such a folding mechanism may be used to convert a stroller from an in-use configuration to a storage configuration. More specifically, the stroller comprises a stroller folding assembly that biases the stroller from the in-use configuration to the storage configuration by the force of gravity exerted on the handle. The stroller folding assembly has linkages that drive folding of the front wheel assembly and rear wheel assembly in response to rotation of the handle into the storage configuration from the in-use configuration.
