A buggy includes a frame, at least one wheel coupled to the frame and formed with a recess, and a braking mechanism provided to the wheel and including a braking rod that has a first end. The braking mechanism is movable between a free position, where the first end of the braking rod is free from the wheel and the wheel is rotatable, and a braking position, where the first end of the braking rod is received in the recess in the wheel such that the rotation of the wheel is limited.

1. A buggy comprising: a frame;at least one wheel coupled to said frame and formed with a recess; anda braking mechanism provided for said at least one wheel and including a braking rod that has a first end, said braking mechanism being movable between a free position, where said first end of said braking rod is free from said at least one wheel and said at least one wheel is rotatable, and a braking position, where said first end of said braking rod is received in said recess in said at least one wheel such that the rotation of said at least one wheel is limited;wherein said braking rod includes an aligning spring disposed for providing pressure to said braking rod toward said recess when said braking rod is not aligned with said recess in said wheel during the movement of said braking mechanism from the free position to the braking position;wherein said braking rod includes a return spring for biasing said braking rod to move in a longitudinal direction, thereby resulting in the movement of said braking mechanism from the braking position to the free position. 2. The buggy as claimed in claim 1, wherein said braking rod further includes a pair of rod sections, said aligning spring interconnecting said rod sections. 3. A buggy comprising: a frame;at least one wheel coupled to said frame and formed with a recess; anda braking mechanism provided to said at least one wheel and including a braking rod that has a first end, said braking mechanism being movable between a free position, where said first end of said braking rod is free from said at least one wheel and said at least one wheel is rotatable, and a braking position, where said first end of said braking rod is received in said recess in said at least one wheel such that the rotation of said at least one wheel is limited;wherein said braking mechanism further includes a moving member that is formed with an engaging surface extending obliquely with respect to an axis of said braking rod, that engages slidably a second end of said braking rod opposite to said first end of said braking rod, and that is rotatable to drive said braking rod to move in a longitudinal direction, thereby resulting in the movement of said braking mechanism between the free and braking positions;wherein said braking mechanism further includes a pedal movable with respect to said moving member for moving said moving member; wherein the pedal includes a protrusion extending towards the moving member and the moving member includes a first pedal engaging surface and a second pedal engaging surface adjacent to the first pedal engaging surface; andwherein said pedal is movable between an initial position wherein said braking mechanism is at the free position, and first and second positions wherein said braking mechanism is at the braking position; wherein the protrusion of the pedal engages the first pedal engaging surface at the free position and the protrusion engages the second pedal engaging surface during at least movement to the second position to the first position; wherein the first position is different from the second position. 4. The buggy as claimed in claim 3, wherein said engaging surface of said moving member is formed with a recess for receiving said second end therein of said braking rod when said braking mechanism is at the braking position. 5. The buggy as claimed in claim 3, wherein said pedal is movable between the first and second positions without moving said moving member. 6. The buggy as claimed in claim 5, wherein said pedal is provided with a torsion spring for biasing said pedal from the first position to the second position. 7. The buggy as claimed in claim 5, wherein said pedal is substantially flush with said frame when at the second position. 8. The buggy as claimed in claim 3, wherein: said pedal is movable from the initial position in a first direction to the first position so as to rotate said moving member in the first direction to result in the movement of said braking mechanism from the free position to the braking position; andsaid pedal is movable from the first position to the second position in a second direction opposite to the first direction, and is further movable in the second direction from the second position to the initial position so as to rotate said moving member in the second direction to result in the movement of said braking mechanism from the braking position back to the free position. 9. The buggy as claimed in claim 8, wherein the first direction comprises a component in downward direction, and the second direction comprises a component in upward direction. 10. The buggy as claimed in claim 3, wherein said moving member is rotatable around a rotational axis parallel to the axis of said braking rod, said engaging surface extending obliquely and radially with respect to the rotational axis. 11. The buggy as claimed in claim 10, where said pedal is rotatable around the rotational axis of said moving member. 12. The buggy as claimed in claim 3, wherein said braking rod includes a return spring for biasing said braking rod to move in a longitudinal direction, thereby resulting in the movement of said braking mechanism from the braking position to the free position.
