A baby jogger includes an upper frame unit, two coupling members, two stop members, two rear frame bars, a rear wheel axle, a plurality of rear wheels, two linking devices, two side bars, a lower frame unit, a mud fender, a front wheel frame and a front wheel. The front wall of each coupling member is connected between the two sidewalls thereof; the rotary members at the two distal ends of the lower frame unit are respectively accommodated in the accommodation space in the two coupling members; the two distal ends of the U-shaped handlebar of the upper frame unit are respectively accommodated in the locating hole in each of the two coupling members. This arrangement avoids accidental finger jam when collapsing the upper frame unit and the lower frame unit, assuring a high level of safety.

1. A baby jogger, comprising: an upper frame unit comprising a tubular and substantially U-shaped handlebar, two connection members bilaterally symmetrically mounted on said U-shaped handlebar near two distal ends of said U-shaped handlebar;two coupling members respectively affixed to the two distal ends of said U-shaped handlebar of said upper frame unit with a respective fastening member, each said coupling member comprising two sidewalls, a locating hole defined in between the two sidewalls at a top side for accommodating the two distal ends of the U-shaped handlebar of said upper frame unit and a pivot hole cut through each of the two sidewalls;two stop members movable up and down with one respective linking device;two rear frame bars each having a top end respectively pivotally connected to the connection members of said upper frame unit and a bottom end connectable to a rear wheel axle;a rear wheel axle comprising two connection portions respectively extended from two distal ends thereof and respectively affixed to the bottom ends of said rear frame bars;a plurality of rear wheels respectively pivotally mounted at the two distal ends of said rear wheel axle;two linking devices arranged at two opposite lateral sides of said upper frame unit, each said linking device comprising a linking member and a rope having one end thereof connected with said linking member and an opposite end thereof affixed to one of said two stop members;two side bars, each said side bar comprising a rear end respectively pivotally connected to the two connection portions of said rear wheel axle and a front end respectively pivotally connected to a lower frame unit;the lower frame unit made of a substantially U-shaped frame bar and having two distal ends thereof respectively pivotally connected to said two coupling members and pivotally connected with the pivot hole on each of the two sidewalls of said coupling members by a pivot pin;a mud fender mounted at a middle part of the U-shaped frame bar of said lower frame unit;a front wheel frame comprising a mounting axle extended from a top side thereof and pivotally connected to said mud fender at said lower frame unit, said mounting axle comprising an annular groove extending around the periphery thereof; anda front wheel pivotally supported on said front wheel frame;wherein:said stop members are respectively inserted into the two distal ends of the tubular U-shaped handlebar of said upper frame unit, each comprising a longitudinal sliding slot respectively coupled to the fastening members at said coupling members so that the fastening members limit the range of upward and downward sliding movement of said stop members, and opposing sidewall portions for stopping a rotary member at each of the two distal ends of said lower frame unit;said two coupling members each further comprise a front wall connected between the two sidewalls thereof and an accommodation space surrounded by the front wall and the sidewalls and kept in communication with a bottom end of the locating hole thereof;the two distal ends of said lower frame unit are respectively and pivotally mounted with one respective rotary member in the accommodation space in each of said two coupling members by the pivot pin in the pivot hole on each of the two sidewalls of each of said coupling members, a coupling hole coupled to one of the two distal ends of said lower frame unit, two sector guide holes disposed at two opposite lateral sides relative to the coupling hole, each said sector guide hole defining an inside wall disposed adjacent to one sidewall portion the associating stop member so that one sector guide hole of each said rotary member is stoppable by one sidewall portion of the associating stop member;said lower frame unit further comprises a plurality of mounting holes;said mud fender comprises a coupling groove downwardly attached to the middle part of the U-shaped frame bar of said lower frame unit, a plurality of mounting posts suspending in said coupling groove and respectively inserted into the mounting holes of said lower frame unit and affixed thereto with fastening members, a rear opening and a through hole in communication with said rear opening, opposing first coupling hole and second coupling hole in communication with said rear opening, and a stop wall defined in said rear opening;a control member is accommodated in said rear opening of said mud fender, said control member comprising two support rods bilaterally disposed at a rear end thereof, two spring members respectively sleeved onto said support rods and inserted with said control member into said rear opening of said mud fender and stopped against the stop wall of said mud fender, a positioning hole disposed at a front end thereof, a sliding slot spaced between the support rods and positioning hole and coupled to the through hole of said mud fender by a pivot pin, said pivot pin comprising a pin body inserted through the sliding slot of said control member so that said control member is movable forwardly by an external force relative to said mud fender to compress said spring members and returnable to a former position by said spring members when the external force is removed, said positioning hole comprising a big diameter portion and a small diameter portion, said small diameter portion being disposed above said second coupling hole of said mud fender, said big diameter portion being kept in axial alignment with said second coupling hole of said mud when said control member is forced forwardly to compress said spring members and reaching the position where one end of said sliding slot of said control member is stopped by the pin body of said pivot pin. 2. The baby jogger as claimed in claim 1, wherein the diameter of said big diameter portion is greater than the diameter of the mounting axle of said front wheel frame; the diameter of said small diameter portion is smaller than the diameter of said mounting axle of said front wheel frame. 3. The baby jogger as claimed in claim 1, wherein each said rotary member comprises a pivot hole disposed at a center and respectively pivotally coupled to the pivot pin in the pivot hole on each of the two sidewalls of each of said coupling members.
