Baby carriage

A baby carriage including a push rod (10) adapted to be switched between two states, one for the face-to-back push mode and the other for the face-to-face push mode, and front wheel casters (14) on the lower ends of a pair of front legs (3) and rear wheel casters (15) on the lower ends of a pair of rear legs (5),

• the pair of front wheel casters (14) and the pair of rear wheel casters (15) respectively having fixed brackets (20, 50) attached to the front and rear legs (3, 5), and rotary yokes (21, 51) rotatably supported by said fixed brackets (20, 50) and rotatably supporting wheels,
• said baby carriage comprising:
• front wheel caster locking means (16) movable between first and second positions and adapted, when in said first position, to engage the rotary yoke (21) of the front wheel caster (14) to inhibit the rotation of said rotary yoke (21),
• rear wheel caster locking means (17) movable between first and second positions and adapted, when in said first position, to engage the rotary yoke (51) of the rear wheel caster (15) to inhibit the rotation of said rotary yoke (51),
• a front wheel return spring (44) urging the front wheel caster locking means (16) to return to the first position,
• a rear wheel return spring (73) urging the rear wheel caster locking means (17) to return to the first position,
• a wire (18) connected at one end thereof to the front wheel caster locking means (16) and at the other end to the rear wheel caster locking means (17), and
• wire position switching means (19) for switching the position of said wire (18) between a front position in which it is relatively close to the front wheel caster (14) and a rear position in which it is relatively close to the rear wheel caster (15),
• the arrangement being such that:
• when said wire (18) is in the front position, the front wheel caster locking means (16) is in the first position and engages the rotary yoke (21) of the front wheel caster (14) and, on the other hand, the rear wheel caster locking means (17) is in the second position and allows the rotation of the rotary yoke (51) of the rear wheel caster (15), and
• when said wire (18) is in the rear position, the front wheel caster locking means (16) is in the second position and allows the rotation of the rotary yoke (21) of the front wheel caster (14) and, on the other hand, the rear wheel caster locking means (17) is in the first position and engages the rotary yoke (51) of the rear wheel caster (15).
