Abstract: A stroller is provided with a handle having a horizontal middle part and two side pipes. The two side pipes are connected to the horizontal middle part by gear trains so as to be turnable about axes perpendicular to an axis of the horizontal middle part, respectively. A folding part operating mechanism is incorporated into the horizontal middle part of the handle. The side pipes can be folded and unfolded relative to the horizontal middle part by turning the horizontal middle part about its axis.

Abstract: A stroller includes armrests, rear legs pivotally joined to the armrests, respectively, a handle pivotally joined to the armrests, and brackets interconnecting the handle and the rear legs. The brackets engage with locking members mounted on lower end parts of side pipes of the handle. Holding members are supported on sides of the side pipes opposite to sides of the same with which the brackets are in contact with the side pipes by pins, respectively. When the stroller is folded in two, stopping parts of the locking members and stopping parts of the holding members are engaged, respectively.

Abstract: A stroller foldable in three includes a pair of front legs, a handle having two side parts, and first and second side connecting bars connecting the pair of front legs and lower end parts of the side parts of the handle. The first side connecting bar is provided with a hook, the second side connecting bar is provided with a loop with which the hook engages to retain the stroller in a folded state, in which the stroller is folded in three. An operating mechanism combined with the handle is interlocked with the hookby wires. The hook is disengaged from the loop by operating the operating mechanism.

Abstract: A stroller includes armrests (3), rear legs (1) pivotally joined to the armrests (3), respectively, a handle (5) pivotally joined to the armrests (3), and brackets (4) connecting the handle (5) and the rear legs (1). The brackets (4) engage with locking members (6) mounted on lower end parts of side pipes of the handle (5). Holding members (10) are supported on sides of the side pipes opposite to sides of the same with which the brackets (4) are in contact of the side pipes b pins (70), respectively. When the stroller is folded in two, the stopping parts (6b) of the locking members (6) and the stopping parts (10a) of the holding members (10) are engaged, respectively.

Abstract: A stroller foldable in three includes a pair of front legs (12), a handle (15) having two side parts (15a, 15a), and first and second side connecting bars (23a, 23b) connecting the pair of front legs (12) and lower end parts of the side parts (15a) of the handle (15). The first side connecting bar (23a) is provided with a hook (26), the second side connecting bar (23b) is provided with a loop (27) with which the hook (26) engages to retain the stroller in a folded state in which the stroller is folded in three. An operating mechanism (25) combined with the handle (15) is interlocked with the hook (26) by wires (34, 35). The hook (26) is disengaged from the loop (27) by operating the operating mechanism (25).

Abstract: A stroller (10) is provided with a handle (15) having a horizontal middle part (30) and two side pipes (18). The two side pipes (18) are connected to the horizontal middle part (30) by gear trains (31, 34) so as to be turnable about axes perpendicular to the axis of the horizontal middle part (30), respectively. A folding part operating mechanism (25) is incorporated into the horizontal middle part (30) of the handle (15). The side pipes (18) can be folded and unfolded relative to the horizontal middle part (3) by turning the horizontal middle part (30) about its axis.
