Referring to FIG. 1 , a multi-purpose trolley provided by the present invention mainly comprises a handle assembly 1 , an object 2 and a plurality of wheel sets 3 ; wherein the handle assembly 1 has two corresponding front frames 11 and 2 The rear frame rod 12, the two side rods 13 and the two horizontal plates 14 are disposed at the upper end of the two front frame rods 11 to provide two pivoting ears 17 for pivoting the two rear frame rods 12 to The two rear frame rods 12 are centered on the two pivoting ears 17 and can be folded forwardly to fit the two front frame rods 11 (please refer to FIG. 4 to FIG. 6 ), and can be opposite to the two front frames The rod 11 is pivoted backwards (as shown in FIGS. 1 to 3), and the bottom ends 11a, 12a of the rods are in a form of a triangular solid support on the ground; and, the two side posts The 13 series is provided with a pivoting point 13a, 13b at each of the two ends, each of which is pivotally connected to the horizontal plate 14 respectively, and a sliding slot 13c is disposed on each of the two rear axles 12 The connecting post 12b is slidably disposed therein to complete the pivoting, so that the two rear posts 13 can be interlocked when the two rear masts 12 are actuated, and the two transverse webs 14 are laterally erected on the two front masts 11 And the second connecting member 14a of the one end portion is pivotally assembled on the two front frame rods 11, and the other end of the horizontal plate piece 14 is connected to the two pivoting points 13a of the two side connecting rods 13 13b is pivotally connected. When the two rear frame rods 12 are centered on the two pivoting seats 21 of the two front frame rods 11, and are folded forward to fit the two front frame rods 11, the two transverse plates are made 14 each with its connecting member 14a as the center, counterclockwise The direction of the swing is flat and the shape of the two front frame rods 11 (see FIG. 4) is flat, so that the two front frame rods 11 and the two rear frame rods 12 become a squatting push rod, which is convenient for the hand. Grasping the urging force and facilitating the pushing of the object 2 (as shown in FIG. 5 and FIG. 6); and when the two rear frame rods 12 are centered on the two pivoting seats 21 with respect to the two fronts When the rod 11 is pivoted backward, the two side rods 13 can be erected and the horizontal sheet 14 can be flattened downwards. The overall handle assembly 1 will be in a stable triangular shape and can be provided as a ladder. In use, the horizontal plate 14 is a stepped plate for the user's foot to step on the upper, which may also be a chair. a cushion plate for the user to directly seat thereon (as shown in FIG. 7); and a hook 16 for each of the two front masts 11 to be hooked on the two rear frame rails 12 a crossbar 12c (shown in FIG. 5) for positioning the two rear masts 12 to lie flat against the two front masts 11, as shown in FIG. 6, and generally attached to the two front masts 11 There is a pressing rod 15 for controlling the linkage rod, the spring or the actuating tip (not shown) accommodated in the two front frame rods 11 to adjust the stretching of the hook rod 16 for rotation. The latching action of the crossbar 12c on the two rear frame rails 12 can be quickly released, so that the two rear masts 12 can be quickly opened to provide immediate and stable support functions if necessary. The structure of the spring and the actuating tip and the related actuating principle therebetween are conventional and not the main features of the present invention, and will not be described here; the object 2 is set as a box having an appropriate size at its two corners. The two front frame rods 11 of the handle assembly 1 are pivotally connected to each other, and the two front frame rods 11 are pivoted by the two pivoting seats 21 The swinging action of the predetermined angle (as shown in FIG. 8) causes the two rear frame rods 12 to be folded and fitted to the two front frame rods 11, and then the two front frame rods 11 are rotated by 90 degrees to be attached. The loading object 2 is flattened into a flat cart form, on which a larger-sized item can be placed, and an object for increasing the size of the carried item is provided; and the inside of the carrying object 2 has an accommodating space. 22, in the embodiment, the accommodating space 22 is arranged to have a sliding rail 23 on the side of the drawer and can be pulled outwards. The way out, of course, the design of the lid 24 can be attached. Or the same cover method as the general trunk (not shown); each of the wheel sets 3 is connected to each part of the object 2 by a wheel frame 31, and each wheel frame 31 and each pivot A wheel 32 is provided. In this embodiment, a wheel set 3 is disposed on the front side of the loading object 2 and a wheel set 3 is disposed at the center of the rear end. When the wheel 32 contacts the ground, the trolley of the present invention can be easily dragged and The weight on the object 2 is moved with the goods; or the wheel set 3 may be disposed at the end of the object 2, so that the object 2 can be placed upright and set at the rear end thereof. The two wheel sets 3 are in contact with the ground, just like the general use of the trunk (as shown in FIG. 9), and can directly push the movement thereof, which is convenient and labor-saving; according to the above description, a trolley of the present invention The structural improvement is to use a special and innovative combination of space types, so that the two front frame rods 11 and the two rear frame rods 12 can be folded and unfolded relative to each other, and can be converted into a general vertical cart and a ladder and a chair. The use of the same form, plus the two front frame rods 11 can also be relative to The loading object 2 is horizontally arranged and transformed into a general flat cart form, and provides the function of increasing the volume and quantity of the carried articles, and the carrying object 2 can be replaced by a general luggage structure, and the invention has various uses. The advantages of the use can achieve the intended purpose of the invention.

The detailed description of the preferred embodiments of the present invention is intended to be limited to the scope of the invention, and is not intended to limit the scope of the invention. The patent scope of this case.

In summary, this case is not only innovative in terms of space type, but also can enhance the above-mentioned multiple functions compared with the customary items. It should fully meet the statutory invention patent requirements of novelty and progressiveness, and apply for it according to law. This invention patent application, in order to invent invention, to the sense of virtue.
