The bases of the divided horizontal rails 16 before and after are axially attached with the bolts 17 so that the base upper surfaces of the respective divided horizontal rails 15 and 16 are in contact with the lower surface of the ceiling plate of the bearing piece 14. The other ends of the crossbars 15 and 16 are prevented from bending and rotating upward, and when the vertical bar 13 is lifted upward, the other ends of the front and rear divided horizontal bars 15 and 16 are bolted to the shaft.
Bend and rotate around 17 to separate the left and right horizontal rails 15 and 16
The base upper surface is provided so as to be separated from the lower surface of the ceiling plate of the bearing piece 14, and the other ends of the divided front and rear horizontal rails 15 and 16 extend left and right,
These extended ends are welded to the left and right end vertical bars 18 and 19 of the loading platform, respectively, and a U-shaped pivoting piece 20 is welded to the left and right end vertical bars 18 and 19 by welding. The corresponding pivoting pieces 21 corresponding to the pivoting pieces 20 are fixed to the left and right vertical rails 11 and 12 respectively, and both are pivotally connected with the pivoting pins 22 to form a pivoting portion 23, and the loading platform is flat. The left and right loading platforms b and c are divided into right and left.

Reference numeral 24 denotes an auxiliary vertical rail provided between the front and rear divided horizontal rails 15 and 16.

An inward channel type bearing piece 25 is provided on the central lower surface in front of and behind the left and right vertical rails 11 and 12, the bases of the left and right holding rails 26 and 27 are fitted into the bearing piece 25, and the shaft is Wear
The other ends of the left and right holding bars 26 and 27 are respectively extended in the width direction of the lower surface at the center of the front and rear sides of the left and right luggage carriers b and c, and are flexibly coupled by the coupling unit 28.

As shown in FIG. 8, the connecting portion 28 is provided with a pair of upper and lower rectangular flat plates 28 ₁ and 28 _{1 on} which the other end of the left holding bar 26 is fitted and inserted at a predetermined interval as shown in FIG. It bridged the vertical plate 28 ₂ between opposed rear edge of the plate 28 _1, 28 _1, rectangular plate 28 _1, 28 ₁
Vertical locking pieces 28 ₃ to weld the base of the right holding rail 27 to the right edge portion is provided above and below the right end portion rearward of the rectangular plate 28 _1, 28 _1, the upper surface to the rectangular plate 28 ₁ of the top center of the and fastening the plate-like spacer 28 ₄ abuts by welding to the lower surface of the crosspieces 13, the locking pieces 2
8 Attach the other extension of the right holding bar 27 to ₃
The other end of the left holding bar 26 is inserted into ₁・ 28 ₁ and the left and right holding bars 26 ・ 27 are attached to the left and right vertical bars 11 ・ 12 in a state where they are stretched with the shaft attaching pins 29. A connecting portion 28 is formed, and the axis of the left holding bar 26 and the axis of the right holding bar 27 are formed so as to be centered at the center as shown in FIG. It is formed in a convex shape.

The bases 3 'of the left and right handles 3, 4
A female screw portion is provided at the 4 'end, and a bolt-shaped locking tool 35 having a dial-shaped grip portion to be screwed into the female screw portion is provided. The base portions 3' and 4 'of the handles 3.4 are connected to the bogie a. When the fittings 35 are fitted into the support cylinders 5 and 6 attached to the front left and right sides, the locking tools 35 are screwed from below into the female screw portions, and the bases 3 'and 4' of the handles 3.4 and 4 are fixed to the support cylinders 5 and 6. The configuration is as follows.

The reference numeral 30 in the figure stands on the left and right vertical bars 11 and 12 to increase the loading capacity of the loading platforms b and c and to add strength against bending of the left and right vertical bars 11 and 12. , 31 are wheel guides erected so as to surround the front and rear sides of the left and right tire wheels 1 and 2 to reinforce the strength of the left and right vertical rails 11 and 12 against bending in the lateral direction, and 32 and 33 are left and right side fences 30. To prevent the load from dropping, and to prevent the load
And a loading fence 34 for expanding the rigidity of the left and right loading platforms b and c between the left and right vertical rails 11 and 12 in a flat plate state. This is a U-shaped leg for placing the cart a on the ground in a stable posture in cooperation with the wheels 1 and 2.

Further, in the embodiment, the main members constituting the loading platform; the central vertical bar 13, the left and right divided horizontal bars 15 and 16, the end vertical bar.
18, 19, auxiliary vertical rail 24, left and right holding rails 26, 27;
The left and right vertical rails 11 and 12 are constructed by appropriately cutting a lightweight and tough aluminum alloy hollow drawn long material having a rectangular cross section, and the left and right handles 3 and 4 and the left and right support cylinders 5 and 6 of the truck a. Side handle 7, left and right side fence 30, wheel guide 31,
Since the packing fences 32 and 33 and the U-shaped legs 34 are also used by appropriately cutting aluminum alloy drawn pipes, the transporter is lightweight, strong, attractive and economical for mass production.

Since the embodiment is constructed as described above, the upper surfaces of the bases of the divided horizontal rails 15 and 16 of the left and right loading platforms b and c abut on the lower surface of the ceiling plate of the bearing piece 14 in a normal state. The left and right ends of the left and right sides 11 and 12 are connected via the left and right tire wheels 1 and 2
The left and right holding bars 26 and 27 and the front and rear loading fences which are axially held by the pivoting portion 23 and are provided below the loading platforms b and c.
Since the right and left vertical rails 11 and 12 are stretched in a state of being stretched by the 32 and 33, the left and right loading platforms b and c are spread and held between the left and right vertical rails 11 and 12 in a flat plate state. Carry the luggage on top.

When the carrier is folded, the bolts 35 which fasten the bases 3 ', 4' of the left and right handles 3, 4 to the support cylinders 5, 6 are released and the handles 3, 4 are released. 4 is pulled out from the support cylinders 5 and 6. One end of the front and rear loading fences 32 and 33 is removed from the left and right side fences 30 and the central vertical rail 13 is lifted. The upper surface of the base 16 is separated from the lower surface of the ceiling plate of the bearing piece 14, and as the vertical rail 13 rises, the left and right vertical rails 11, 12 pull the grounding portions of the tire wheels 1 and 2 on the ground with the bolt 17 as the axis. Meanwhile, the left and right loading platforms b and c are folded in a substantially rectangular shape in close proximity to each other, and at the same time, the left and right holding bars 26 and 27 project rearward as viewed from above by the shaft mounting pins 29 of the connecting portion 28. Folded into a shape.

On the other hand, the pulled out handles 3 and 4 also release the fastening of the fastener 9 to the handle 4 and slide the slide cylinder 8 to the middle of the handle 4 while the other end 7 "of the horizontal handle 7 is moved. Is turned horizontally to adjust the width of the left and right handles 3.4 to the width of the left and right support cylinders 5 and 6, and then adjust the width of the handle 3.4 to the opposite direction so that the handles 3.4
The bases 3 'and 4' are inserted into the support cylinders 5 and 6, and the ends of the bases are locked by the locks 35.

The transport vehicle whose length in the length direction and the width direction is reduced is stored in a trunk of a private car.

[0023]

As described above, the present invention is constructed as described above. In a normal state, loads are loaded on a trolley, and the loads are transported while grasping the handlebars in the same manner as a normal rear-car type transport vehicle.

When not in use, pull out the left and right handles from the support cylinder, then fold the bogie in the center left and right direction, fold the bogie so that the left and right tire wheels are aligned, and secure the pulled out left and right handles with the fasteners to the handles. When released and fastened to the folded support cylinder, the length and width of the transport vehicle can be reduced and stored, so that the transport vehicle is not bulky without taking up space, and is a convenient transport vehicle.
