Description

Cart for multi-purpose folding type

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose folding cart, and more particularly, to a multipurpose folding cart configured to be used in three different applications, namely cart, dolly, and dolly, depending on the type of article to be loaded.

Generally, a hand car or a carrier carries various articles by pushing or pulling a structure having a plurality of wheels.

However, in the case of such a handkerchief or a carrier, it may be difficult to carry it depending on the article to be transported. For example, it is difficult to carry the article with a long shape such as a paper sheet by a handkerchief.

In addition, in the case of a cart for storing various items shopping at a large discount store, the storage box has a shape of a hexahedron in which an upper portion is opened to form an inner space. It is difficult to load and move the long form of the article.

In addition, since the size of the internal space of the cart is limited, there is a problem that it is difficult to store a bulky article such as a TV or a fan in a storage box.

In addition, when the article is inserted or removed, the article must be inserted into or removed from the upper side of the storage box, so that there is a problem that entry and exit are inconvenient when the volume of the article is large.

Therefore, although it is classified as suitable for a handkerchief, a transporting machine, and a cart, according to the form of the article, all the structures are provided, and the cost is further reduced.

The supporting bar 340 is for supporting the article inside the hermetic container 300. Both ends of the supporting bar 340 pass through the one end of the vertical member 312 and are rotatably connected to each other through the through hole.

The side plate member 310, the first side plate assembly 320, the second side plate assembly 330 and the support bar 340 may be made of steel, aluminum, iron, or synthetic resin as described above.

Referring to FIGS. 1, 2, and 7, the handle 400 is attached to the support plate 210 and is held by a user. The handle 400 is reinforced along the inner longitudinal direction of the hollow handle 410 having a ' A plurality of connection bars 412 are provided at regular intervals and the handle 410 can be rotated in a horizontal direction or a vertical direction with respect to the support plate 210 as needed.

7, a pivoting member 420 having a spring insertion hole 422 formed therein is press-fitted and fixed at a predetermined depth through both opened ends of the handle 410, and the coil spring 424 is inserted into the spring insertion hole 422. [ Hole 422, and the long hole 422a is communicated with the spring insertion hole.

One end of the pin member 426 passes through the coil spring 424 and the other end of the pin member 426 is inserted into the spring receiving hole 422 through a support member 430 are inserted into the insertion grooves 432 of the insertion opening 432.

A through hole (not shown) is formed at one side of the pin member 426, so that both ends of the connecting bar 428 are connected to the pin member 426 through the through hole.

The support member 430 is coupled to the pivoting member 420 through a pin member 440. The support member 430 has an opening 434 having a ' A bolt (not shown) is inserted through the opening 434 and the rectangular frame 110 and a nut (not shown) is connected to the pin member 426 at the other end of the support member 430, A plurality of insertion grooves 432 are formed at intervals of 90 [deg.] From each other, and the turning operation of the handle 410 will be described in the following operation.

At this time, the handle 400 may be made of steel, aluminum, iron, or synthetic resin.

Hereinafter, the operation of the present invention having the above-described configuration will be described.

8 to 10 are perspective views showing the use state of the cart according to the present invention, respectively. Referring to FIGS. 1 and 10, the first side plate assembly 320 and the second side plate assembly 330 are upright in a direction perpendicular to the support plate 210, The first side plate and the second side plate assemblies 320 and 330 are maintained in an upright state and the handle 410 is installed in a direction perpendicular to the base plate 210 ).

In such a cart state, it is possible to accommodate a small box, a sheet of paper or the like in the housing unit 300 and to move the housing through the casters 112 and 122.

4 and 8, the first side plate assembly 320, the second side plate assembly 330, and the support bar 340 are folded side by side with the support plate 210, (310) is placed on the upper surface of the support plate (210), and it is possible to mount various boxes or the like having a large volume or size, which is difficult to be accommodated in the cart in such a bogie state, to move through the casters It is possible.

5 and 9, the first side plate assembly 320, the second side plate assembly 330, and the support bar 340 are folded side by side with the support plate 210, and the side plate support 310 Is placed in parallel on the upper surface of the support plate 210 and the handle 410 is in the state of a dolly rotated in parallel with the support plate 210.

7, when the user holds the connecting bar 428 and lifts the pin 426 upward, the pin member 426 is lifted inside the slot 422a while the coil spring 424 is compressed, 426 are released from the one insertion groove 432 of the support member 430 (see the second figure in Fig. 7).

When the tilting member 420 and the handle 410 are rotated in parallel with the support plate 210 in this manner and the user releases the connection bar 428, the coil spring 424 is stretched by the restoring force, The pin member 426 is engaged with the other insertion groove 432 of the support member 430 (see the third figure in Fig. 7) while the second engagement member 426 descends inside the elongated hole 422a.

In such a dolly state it is possible to mount a relatively long article, such as a sink, refrigerator, or dresser, and move it through the wheels 124 and 134.

In the above process, when the structure is changed as a cart, a cart, and dolly according to need, the structure is changed by dolly, so that it is difficult to carry or move a bulky item or a bulky item This is easy.

Further, according to the type of the article to be loaded, it is possible to use it while changing the structure by bogie, dolly, and cart, so that no additional cost loss is required.

In addition, when the multipurpose folding cart according to the present invention is not used, it can be used in a camping field while being loaded on a vehicle because it has a relatively compact structure in a folded state.

In addition, the present invention is applicable to various industrial fields. In other words, it can be used for three purposes as described above, while being carried by a general person, a courier article, a wagon, a tile, a boiler, a sink, an interior contractor related to all companies,

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, the invention is not limited to the disclosed exemplary embodiments, and various changes and modifications may be made by those skilled in the art within the technical scope of the invention. Of course.
