Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a load transporting trolley used for storing and transporting loads, or storing loads in a stored state.

That is, the present invention provides a truck main body forming a loading surface, a front frame erected from the front end of the truck main body,
This invention relates to a cart for transporting loads, which is comprised of a rear frame that stands upright from the rear end, and side frames that are removably installed at both ends.

Such cargo transport carts are used, for example, to transport parcels at post offices and department stores. Here, since the top surface of the cart for transporting goods is open, parcels, parcels, etc. can be easily inserted into the cart. On the other hand, since the top surface is open, there is a risk that the item may fall off due to vibration during transportation or be stolen.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cart for transporting goods that can easily be loaded with items, can prevent items from falling off or stolen, and can also be easily taken out.

In order to achieve the above-mentioned object, the cargo conveyance truck of the present invention has rails in the left and right directions attached to the upper ends of the front frame and the rear frame, respectively, and a foldable upper frame in the left and right directions, and the middle part is provided with a foldable upper frame. An engagement piece is fixed to the middle of the rail, and has rollers attached to a folding shaft positioned alternately within the rail and on the rail, and a stopper is provided for the upper frame fixing portion of the rail, and an engagement piece is removable from the fixing stopper. is attached to the end of the upper frame.

According to the cargo conveyance truck of the present invention having such a configuration, the following effects can be expected. That is,
By folding the upper frame and opening the upper surface, articles can be easily inserted, and by expanding the upper frame and closing the upper surface, it is possible to prevent articles from falling off or being stolen. Furthermore, by folding the upper frame and engaging the engaging piece with the fixed stopper, the article can be reliably taken out while the open portion is securely secured. Furthermore, since the upper frame is fixed in the middle and can be opened and closed from both the left and right sides, articles can be inserted and taken out from both the left and right sides as desired.

An embodiment of the present invention will be described below based on the drawings. 1 is a trolley body that forms a loading surface on its upper surface;
A pair of left and right caster wheels 2 are arranged on the front lower surface, and a pair of left and right fixing wheels 3 are arranged on the rear lower surface.
is installed. A front frame 4 is erected from the front end of the truck body 1, and a rear frame 5 is erected from the rear end. The front frame 4 and the rear frame 5 are provided with gripping rods 6 and 7 for manual pushing. Side frames 8 are removably disposed at both ends of the truck body 1, respectively. That is, the side frame 8 consists of a lower mesh body 8A and an upper mesh body 8B connected to the lower mesh body 8A via a connector 9 such as a coil body, and includes a front frame 4 and a rear frame 5.
Insert the lower mesh body 8A from above into the guide members 10 and 11 attached to both sides of the
The locking pins 12 and 13 attached to the front and rear ends of the front frame 4
The rear frame 5 is attached by engaging the locking members 14 and 15 attached to both sides of the rear frame 5. A brake device 16 is provided opposite each of the fixing wheels 3, and for operating these brake devices 16,
The front frame 4 and the rear frame 5 are provided with a manual brake operating section 17,
18 and foot-operated brake operating sections 19 and 20 are provided. Rails 21 and 22 in the left and right directions are attached to the inside of the upper ends of the front frame 4 and the rear frame 5, respectively, and these rails 21 and 22 have a U-shaped cross section and are attached with their open portions on the inside. Reference numeral 23 denotes an upper frame that can be folded in the left-right direction, and includes a plurality of folding shafts 24 (nine in the embodiment) arranged in parallel in the left-right direction in the front-rear direction, and a large number of links 25 connected by these folding shafts 24. It consists of a rod 26 extending in the front and back direction passed between these links 25, and rollers 27 and 28 are attached to both ends of each folding shaft 24, respectively. One folding shaft 24a in the center has no rollers and is attached to the block 2 mounted inside the rails 21, 22.
It is fixed at 9,30. The rollers 27 and 28 attached to the remaining folding shaft 24 are
1 and 22 and on the rails 21 and 22 alternately. That is, when viewed from both sides, the first and third rollers 27, 28 are located within the rails 21, 22, and the remaining second and fourth rollers 27, 28 are located within the rails 21, 22.
are located on the rails 21 and 22. A fixed stop 31 is mounted on the front rail 21 on the left near the block 29, and a fixed stop 32 is also mounted on the rear rail 22 on the right near the block 30. At the front left end and rear right end of the upper frame 23, engaging pieces 3 are connected via brackets 33, 34 and shafts 35, 36, respectively.
7 and 38 are rotatably attached, and by their rotation, they can be engaged with and disengaged from the fixed stoppers 31 and 32.

The cargo transport truck configured in this manner can be moved in a free direction by pushing or pulling it via the gripping rods 6, 7. And each brake operation part 1
By operating any one of 7, 18, 19, and 20, the brake device 16 can be actuated to apply the brakes. Upper frame 2 when driving
3 is expanded as shown in FIGS. 2 to 4, and its upper surface is closed. At this time, the engaging pieces 37, 38
is rotated into the upper frame 23. In this state, to open the top surface, first fold the folding shafts 2 located on both sides.
4 to move the upper frame 23 to the center side. As a result, the upper frame 23 is folded in the left and right direction as shown in FIG. And it is done reliably.
In the folded state, the shafts 35, 36 are displaced so that their axes are in the left-right direction, and in this state, the engaging pieces 37, 38 are rotated around the shafts 35, 36 to close the fixed stopper. 31 and 32. This prevents the upper frame 23 from returning even if the user releases his or her hand. When expanding the upper frame 23 again, the engaging pieces 37,
38 to remove the fixed stoppers 31 and 32, and then pull the upper frame 23 toward both sides.

In the above description, the left and right sides of the upper frame 23 are folded, but this can also be done only on one side.
