Abstract
A stroller includes a frame, a first locking mechanism, a folding mechanism and a second locking mechanism. The frame is configured to be folded and unfolded between a folded state and an unfolded state. The first locking mechanism is disposed on the frame and for locking the unfolded frame and restraining the frame from being folded when the frame is in the unfolded state. The folding mechanism is movably disposed on the frame and connected to the first locking mechanism for driving the first locking mechanism to allow the frame to be folded. The second locking mechanism is disposed on the folding mechanism and separably abuts against the frame for restraining the folding mechanism from driving the first locking mechanism so as to lock the unfolded frame.
Claims15
A stroller comprising:
- a frame configured to be folded and unfolded between a folded state and an unfolded state, the frame comprising a handle, at least one front leg, at least one rear leg and a tube, the at least one front leg and the at least one rear leg being pivoted to the handle, and the tube being pivoted to the at least one front leg and the at least one rear leg;
- at least one first locking mechanism disposed on the frame and for locking the unfolded frame and restraining the frame from being folded when the frame is in the unfolded state, and the at least one first locking mechanism being disposed between the handle and the at least one front leg;
- a folding mechanism movably disposed on the frame and connected to the at least one first locking mechanism for driving the at least one first locking mechanism to allow the frame to be folded, and the folding mechanism being movably connected to the at least one front leg;
- and
- a second locking mechanism disposed on the folding mechanism and separably abutting against the frame for restraining the folding mechanism from driving the at least one first locking mechanism so as to lock the unfolded frame, and the second locking mechanism separably abutting against the tube.
A stroller comprising:
- a frame configured to be folded and unfolded between a folded state and an unfolded state, the frame comprising a handle, at least one front leg, at least one rear leg and a tube, the frame further comprising at least one first pivoting joint and at least one second pivoting joint, the at least one first pivoting joint being fixed on the at least one front leg, and the at least one second pivoting joint being fixed on the handle;
- at least one first locking mechanism disposed between the handle and the at least one front leg and for locking the unfolded frame and restraining the frame from being folded when the frame is in the unfolded state, and the at least one first locking mechanism being disposed between the at least one first pivoting joint and the at least one second pivoting joint;
- and
- a folding mechanism movably connected to the at least one front leg and connected to the at least one first locking mechanism for driving the at least one first locking mechanism to allow the frame to be folded.
A stroller comprising:
- a frame configured to be folded and unfolded between a folded state and an unfolded state, and the frame comprising a handle, at least one front leg, at least one rear leg and a tube;
- at least one first locking mechanism disposed between the handle and the at least one front leg and for locking the unfolded frame and restraining the frame from being folded when the frame is in the unfolded state, the at least one first locking mechanism comprising:
- an engaging component slidably disposed inside the at least one front leg and movable between a first position and a second position, the engaging component engaging with the handle when the engaging component is located at the first position;
- a connecting component slidably connected to the at least one front leg and connected to the engaging component and the folding mechanism, the folding mechanism driving the engaging component to slide by the connecting component;
- and
- a recovering component disposed inside the at least one front leg and abutting against the engaging component, the recovering component biasing the engaging component to move from the second position to the first position;
- and
- a folding mechanism movably connected to the at least one front leg and connected to the at least one first locking mechanism for driving the at least one first locking mechanism to allow the frame to be folded.
