Abstract:
A sports utility stroller, comprising:a boundary frame, comprising: a bottom frame having a supporting surface; a top frame, defining a top opening, spaced apart from said bottom frame in a vertical direction; and a boundary shelter supported by said top frame to define a playpen cavity within said boundary shelter, said top frame and said bottom frame; a stroller frame, comprising: a pair of side frames, which supports two sides of said boundary frame, each comprising a first side frame leg and a second side frame leg pivotally connected with each other in a cross manner to form a pivotal â€œXâ€  structure; a pair of front stroller wheels rotatably attached to two bottom ends of said first frame legs respectively; a pair of rear stroller wheels rotatably attached to two bottom ends of said second frame legs respectively; and a handle frame comprising two handle arms upwardly extended from said side frames respectively, wherein said two handle arms of said handle frame are pivotally connected to two upper ends of said second side frame legs respectively in such a manner that bottom ends of said handle arms are substantially biased against said first side frame legs respectively at said unfolded position, wherein said handle frame further comprises a pair of sliding guiders each having a bottom guiding slot, provided at said bottom ends of said handle arms respectively in such a manner that when said handle arm is folded to said respective first frame leg, the sliding guider is slid along said first side frame leg by slidably receiving said first side frame in said guiding slot, so as to guide said bottom end of said handle arm to substantially bias against said first side frame leg; and a pair of locking arrangements securely locking up said two side frames respectively so as to retain said boundary frame at an unfolded position, wherein at said unfolded position, said top frame is lifted up from said bottom frame to form said playpen cavity having a predetermined depth, and at a folded position, said first and second side frame legs are pivotally folded to drop said top frame towards said bottom frame, so as to minimize said depth of said playpen cavity.
