<p>A three-wheel golf bag cart folding device includes a main shaft 1, a rear wheel set 10, a link mechanism 2, a lower cart frame 3, a front wheel set 30 and an upper cart frame 4, where the upper cart frame can be pulled (A, figure 8) and rear wheels 11 subsequently driven by the link mechanism to fold or unfold, such that the golf bag cart can be folded into a flat shape (figure 11) so as to reduce the storage space and aid transportation. The link mechanism is installed on the main shaft and has a rocker rotating member (21, figure 3) which drives a sliding member (24) to displace sideways when the upper cart frame is folded. A connecting member (25) attached to an axle (111) of the wheel is caused to rotate inwards (figure 9) due to the sideways displacement of the sliding member, possibly as a result of the inter-engagement of a rack (243) on the sliding member and gears (251) on the connecting member. The lower cart frame, upper cart frame and a handle 42 may have triangular shapes which nest within each other when folded flat.</p> |
