A lightweight, collapsible golf trolley is disclosed comprising an extruded elongate chassis member 1 of lightweight metal or alloy, e.g. aluminum. The chassis member 1 is of an inverted channel section with two downwardly and outwardly flared side wall sections 2, 3 against which are pivoted the wheel struts 4, 5 which are likewise lightweight alloy extrusions. Preferably the struts are in two halves forming a parallel linkage with the chassis and the wheel brackets 13. Hinged to the forward end of the chassis is a handle 27 which can be folded to a position alongside the chassis thus collapsing the wheel struts via the tie 37.

In a collapsible golf trolley having an elongate chassis member forming the principal structural element of the trolley, a pair of wheel struts pivotally connected at one end to the chassis member intermediate the ends thereof and normally lying at an angle to each other on opposite sides of the median plane of the trolley, said wheel struts each carrying at their distal ends on opposite sides of the trolley a ground engaging wheel, upwardly extending bracket means at each end of the chassis member for receiving and retaining thereon a golf bag containing a plurality of golf clubs, an elongate handle pivotally connected to said chassis member at one end and pivotable between a first, extended position in which the handle extends from the chassis member in a direction generally coaxial therewith and a second, collapsed position in which the handle substantially lies alongside the chassis member, and rigid link means connected directly between said handle and said wheel struts, whereby, when the handle is in its first, extended position the wheel struts are splayed outwardly on opposite sides of the trolley, and, when the handle is in its second, collapsed position, the wheel struts pivot inwardly towards the chassis member so as to lie, in the collapsed condition of the trolley, substantially alongside the chassis member with the wheels closely adjacent thereto on opposite sides, the improvements comprising: (a) the chassis member comprising an elongated, inverted channel-shaped, lightweight alloy extrusion having a cross-section that is uniform along the length of the extrusion, said cross-section providing on the underside of the chassis member a pair of downwardly divergent sidewalls defining the opposite sides of the inverted channel, said downwardly divergent sidewalls being symmetrically disposed on opposite sides of the median plane of the channel at a predetermined angle corresponding to the angle of divergence of said wheel struts to said median plane when said struts are in their splayed out position on either side of the trolley, said downwardly divergent sidewalls providing downwardly divergent abutment surfaces against which the wheel struts are pivoted at their proximal ends and determining the angle of divergence of the wheel struts when in their splayed out position on opposite sides of the trolley; and (b) the wheel struts pivotally mounted at their proximal ends against said downwardly divergent abutment surfaces provided by said downwardly divergent sidewalls, each of said wheel struts comprising two parallel lightweight alloy extrusions having substantially identical uniform channel-shaped cross-sections extending the length of each extrusion, the free edges of the opposite sidewalls defining each channel of each pair of extrusions forming each of the two wheel struts slidably mating one within the other, each of said two parallel extrusions forming each of the two wheel struts being pivotally connected at their proximal ends to the elongate chassis member in pivotal abutting relation to a respective one of the two downwardly divergent abutment surfaces provided on the underside of the chassis member and, at their distal ends, each to a respective wheel bracket mounting a respective one of the two ground wheels, each of said two parallel extrusions forming each of the two wheel struts thus forming, together with the chassis member at one end and the wheel brackets at the other, a parallel linkage constrained to move between the splayed and collapsed positions of each wheel strut, each in an oppositely inclined plane defined by the angles of the downwardly divergent sidewalls on the underside of said chassis member.
