A foldable rollable golf bag trolley comprising a push handle assembly, a front leg assembly a left rear leg assembly, a right rear leg assembly, a folding mechanism having two universal joint sub-assemblies, a series of hubs and ramp discs, wherein said components of the folding mechanism are aligned about a central axis of a main pivot shaft in a first position. The folding mechanism further comprising a plurality of locking gears and springs wherein the two universal joint sub-assemblies and a left and right ramp disc cause a left rear hub and a right rear hub to move in two dimensions when the folding mechanism is engaged in a second position.

The invention provides a frame folding mechanism, a frame locking mechanism, a backrest unlocking mechanism and a stroller. A handle, a front foot, a seat portion and a linking member of the frame folding mechanism form a planar linkage mechanism. The handle and the front foot can be driven to rotate and fold toward a rear foot, so as to drive the seat portion to rotate and fold. The frame locking mechanism can drive a sliding member and a frame expansion locking member to slide by an unlock driving mechanism, such that the frame expansion locking member disengages from a handle locking hole and a front foot locking hole to unlock a frame. The backrest unlocking mechanism has a backrest locking member. The unlock driving mechanism can drive the backrest locking member to slide, such that the backrest locking member disengages from a backrest portion to unlock the backrest portion.

An infant stroller apparatus includes a front leg frame, a rear leg frame and a handle frame. The front leg frame has a first side portion fixedly connected with a first stop abutment. The rear leg frame has a second side portion having a protrusion. The handle frame has a side segment fixedly connected with a second stop abutment, the first and second side portions and the side segment being pivotally connected with one another about a common first pivot axis. The protrusion is restrictedly positioned between the first and second stop abutments when the infant stroller apparatus is in a deployed state.

A folding golf cart including a chassis, a main rod, a handle, a handle-connected seat body, a front wheel, two rear wheels, and two sets of foldable rear wheel frames. The chassis includes two chassis rods, a front-connected seat body, and a rear-connected seat body. The front ends of the two chassis rods are fixed to the front-connected seat body. The rear ends of the two chassis rods are fixed to the rear-connected seat body. The handle is rotationally connected to the handle-connected seat body. The bottom part of the main rod is hinged to the rear-connected seat body. The two rear wheels are respectively connected to the sides of the rear-connected seat body through the foldable rear wheel frames. The middle part of the front-connected seat body is connected to the front wheel through a front wheel retraction and extension device.

A fixed rod and a pull rod slidingly engageable in the fixed rod with a plug mounted inside the bottom end of the pull rod and a push button mounted at the bottom of the plug. The push button has a first position and a second position with respect to the plug. When the push button is in the first position with respect to the plug, the pull rod is slidable up and down inside the fixed rod. When the push button is located in the second position with respect to the plug, the pull rod is removable from the fixed rod.

A folding push cart that includes a cart body frame and a storage bag. The front, rear, left, and right vertical surfaces of the cart body frame each includes more than one set of cross-hinged diagonal rods. The bottom of the cart body frame is hinged on the hinge base. The bottom plane of the cart body frame is supported by two left and right folding rod groups, which are hinged on the horizontal slot of the hinge seat on the front and rear vertical surfaces. When opened in place, it can be supported, and it also has a correcting effect on the hinge seat.

A hand truck includes a base that is able to roll along the ground underlying the base and a push handle coupled to the base. A pivotable toe plate is coupled to a lower end of the base.

The disclosure provides a wheeled container assembly (10) and a handle assembly (20) for a container, the handle assembly comprising a pair of pa ra Nelly disposed leg members (24, 26), each leg member comprising a first leg segment (32) articulable to the container, a second leg segment (34) telescopically displaceable with respect to said first leg segment, and a third leg segment (36) telescopically displaceable with respect to said second leg segment; a bridge member (40) rigidly extending between an upper portion the first leg segments, and a manipulating handle (42) rigidly extending between a top portion of the third leg segments; the leg members are configurable between a locked extended position and a locked retracted position; a primary locking mechanism (120); and a secondary locking mechanism (50); and wherein retracting the third leg segment into the second leg segment is facilitated after retraction of the second leg segment into the first leg segment.

A baby carriage includes a handle, a first fixing member, a second fixing member, a rear leg, a front leg, an unlock member, a first lock member, a rotating member and a pulling member. The first lock member engages with the first fixing member and the second fixing member to lock the handle, the rear leg and the front leg at a first unfolded position. When the unlock member pulls the pulling member, the pulling member drives the rotating member to rotate, a first inclined driving surface of the first fixing member pushes the rotating member toward the first lock member, and the rotating member pushes the first lock member toward the second fixing member to disengage the first lock member from the first fixing member.

A connecting mechanism includes a first joint, a second joint, a lock pin, an unlock operating member and a stationary base. The first joint is pivotally connected to the second joint. The lock pin is movably disposed between the first joint and the second joint and configured to lock or unlock the first joint and the second joint. The unlock operating member is connected to the lock pin and configured to drive the lock pin to disengage from the first joint or/and the second joint, so as to unlock the first joint and the second joint. The stationary base is connected to the first joint or the second joint and configured to be detachably connected to a baby carriage.
