Control device for folding and expanding a baggage cart

A control device for folding and extending a baggage cart which comprises a substantially U-shaped support member (20) including a horizontal first bight (21) and two parallel vertical legs (22) each extending downwardly therefrom, a substantially U-shaped handle portion (10) having a horizontal second bight (11) and two parallel elongated stands (16) each extending downwardly therefrom and each respectively pivotally engaged with a corresponding one of said vertical legs (22) of said support member (20), a base member (40) pivotally engaged with said support member (20) at a lower portion of each of said vertical legs (22), said control device comprising:

• a movable sleeve member (60) movably mounted on said pair of elongated stands (16) of said handle portion (10) and comprising a recessed portion formed by a top plate (65) and side walls, a pair of lug portions (63) each laterally formed on said movable sleeve member (60) and offset from said recessed portion, each having an opening formed in said top plate, and each having a vertical passage (62) longitudinally defined therein for receiving a corresponding one of said elongated stands (16) of said handle portion (10) such that said sleeve member (60) is able to move along said elongated stands (16) of said handle portion (10), said recessed portions and vertical passages having a common opening (64) facing downwardly, whereby, said sleeve member (60) is able to be moved downwardly along said pair of elongated stands (16) of said handle portion (10) to a first position where said first bight and an upper portion of each of said pair of vertical legs (22) of said support member (20) are received within said recessed portion (64) of said sleeve member (60) with said first bight (21) of said support member (20) abutting against said top plate (65) of said sleeve member (60) such that each of said elongated stands (16) of said handle portion (10) is respectively fixed to a corresponding one of said vertical legs (22) of said support member (20), thereby fixing said handle portion (10) to said support member (20), and said sleeve member (60) is able to be moved upwardly along said pair of elongated stands (16) to a second position where said first bight (21) and said vertical legs (22) of said support member (20) are detached from said recessed portion (64) of said sleeve member (60) such that said elongated stands (16) of said handle portion (10) are able to pivot relative to said vertical legs (22) of said support member (20), thereby folding said handle portion (10).
