Description

Folding transport cart{FOLDING TYPE MOVING CART}

The present invention relates to a foldable transport cart, and more specifically, it can be folded or unfolded in a simple manner without requiring a lot of force, and when folded, the volume and size can be significantly reduced, and the volume and size when folded can be significantly reduced. According to the possibility, it can be easily stored in a storage place such as a trunk of a vehicle, a warehouse, etc. to a foldable transport cart that can maximize the space utilization of the storage place.

In general, a transport cart can be used for various purposes, such as for the user to conveniently transport heavy or bulky luggage by attaching wheels to the bottom. For example, transporting goods in shopping centers and food in restaurants and hotels. It is widely used as a means for transport and a transport cart for transporting parts in factories.

As described in Korean Patent Registration No. 10-0454804, the transport cart is composed of a plurality of trays and a support means for supporting the trays, a handle formed on the uppermost tray, and a wheel formed on the lowermost tray. For assembly type, that is, a coupling pipe is attached to each corner of the tray, and a support rod is formed between the trays, and the coupling pipe is connected by a coupling hole, and a handle is attached to the coupling hole and a wheel is fastened to the coupling pipe of the lowermost tray. I made this easy.

In addition, in Korean Registered Utility No. 20-0345660, a shelf in which an assembly tube is integrally formed at the corner of the frame, and a pair of fixing members inserted into the assembly tube of the shelf but having a locking projection on the inner circumference and a taper on the outer circumference. And, the assembly of the bar is inserted into the assembly tube of the shelf, but formed with a locking groove corresponding to the locking protrusion of the fixing member, and a wheel that is coupled to the lower end of the holding rod to facilitate movement, thereby increasing the assembly performance. .

These prior technologies have the effect of increasing the convenience of manufacturing, but the volume and size of the transport cart is too large to occupy a large storage area when stored or transported after use, and when heavy items are loaded, the pushing force is reduced to one side. There is a problem that the object falls off and is damaged by folding naturally when it is biased, and there is a disadvantage that a lot of difficulties are caused in driving.

In the folding transport cart of the present invention, it is a side view showing a fully folded state.

Referring to the above drawing, in the present embodiment, folding means folding, unfolding means unfolding, and hinge (H) means a hard chip structure or a rotation axis so that a link or a support member can be rotated. It refers to a structure that is connected and installed, and since the hinge corresponds to a publicly known technology, a detailed description thereof will be omitted.

The foldable transport cart of the present invention includes first to fourth leg members 111, 112, 113, and 114 installed in a vertical direction at four corners of a square.

In the folding transport cart of the present invention, an assembly-type wheel member 120 is installed under the first to fourth leg members 111, 112, 113, and 114 for movement and transport.

A hinge H is installed on the first to fourth leg members 111, 112, 113, and 114 so that the support member 130 is rotatable. In the present embodiment, the support member 130 is composed of three stages, but is not limited thereto and may be formed in more than one. The support member 130 is a means by which an object can be seated when in use, and has an effect of carrying an object in an actual cart.

The handle 135 may be a hinge (H) installed at the end of the uppermost support member 130 so as to be foldable. Accordingly, when the foldable transport cart is folded, the handle 135 is also folded and unified in a straight shape, thereby making it easy to store in a vehicle or the like.

It is preferable that a drop-preventing jaw 138 is formed on the upper edge of the support member 130 so that the object placed on the support member 130 does not fall.

The support member 130 is divided into halves and configured so that both sides rotate downward (to be folded) around a rotation shaft S installed in the middle. That is, based on the rotation shaft (S), the support member 130 can maintain an unfolding state that maintains a flat unfolded state so that objects can be placed thereon, and, on the contrary, a foldable transport cart is warehoused without moving objects. When stored in the back, the support member 130 is configured to maintain a folding state in which both sides rotate downward around the rotation shaft S so that the support member 130 can be folded in half.

A folding vertical rod 140 for connecting the rotating shaft S to each other is installed in the vertical direction on the rotating shaft S. The folding vertical rod 140 is used when the support member 130 is folded in half by lifting the rotation shaft S upward. For example, when a plurality of support members 130 are disposed in a plurality of rotation shafts S in a direction perpendicular to the ground, a plurality of rotation shafts S may be connected to each other on the vertical bar 140 , A plurality of rotation shafts (S) may be folded or unfolded at the same time.

The folding transport cart of the present invention includes a first two-stage link 150 and a second two-stage link 160 that are configured to be folded and unfolded.

The first two-stage link 150 and the second two-stage link 160 are arranged in a “V” shape, for example, and the first two-stage link 150 includes a second leg member 112 and a vertical rod for folding ( 140) is installed in the diagonal direction between the hinge (H), so that the support member 130 to maintain a horizontally unfolded state.

And the second two-stage link 160 is a hinge (H) is installed in the diagonal direction between the fourth leg member 114 and the folding vertical rod 140, so that the support member 130 to maintain a horizontally unfolded state. do.

The first two-stage link 150 and the second two-stage link 160 are each composed of two links, each of the links is hinged (H) is connected to be rotatably installed, the hinge (H) portion of the stopper 155 Is formed to maintain the unfolded state, that is, configured to maintain the unfolded state without bending (see FIG. 4).

A link handle 170 is hinged between the first two-stage link 150 and the second two-stage link 160.

The link handle 170 is composed of a link unit 171 connected to the first two-stage link 150 and the second two-stage link 160, and a handle unit 172 connected to the middle of the link unit 171. The link portion 171 and the handle portion 172 are connected by a hinge (H).

When using the folding carrying cart of the present invention, when the link handle 170 is pressed downward, it is configured to maintain the unfolding (unfolding) of the first two-stage link 150 and the second two-stage link 160 ( 1).

Conversely, during storage, when the link handle 170 is lifted upward, the support member 130 is divided into halves, around the rotation shaft S, by raising the folding vertical rod 140 It is configured to be folded in half and stored (see Fig. 3).

It will be described with respect to the effect of the folding transport cart of the present invention configured as described above.

1 is a flatly unfolded state (unfolded state) so that objects can be placed on the support member 130 when using the folding carrying cart of the present invention, and when pressing the link handle 170 downward, the link handle 170 The unfolding (unfolding) of the first two-stage link 150 and the second two-stage link 160 may be maintained.

As shown in Figure 4, when storing the folding transport cart of the present invention, when lifting the link handle 170 upward, by raising the vertical rod 140 for folding, the first two-stage link 150 And by folding (folding) the second two-stage link 160, as shown in Figs. 5 and 6, the support member 130, which is divided in half, is folded in half with the rotation shaft S as the center. Can be stored.

As described above, the present invention can be folded or unfolded in a simple manner without requiring much force, and when folded, the volume and size can be significantly reduced compared to the conventional one, and the volume and size when folded can be significantly reduced. Accordingly, it can be easily stored in storage places such as the trunk of a vehicle, warehouse, etc., thereby maximizing the use of space in the storage area, and can be stored in restaurants and houses with a small space, thus preventing theft accidents in advance. It has the effect of being very easy to carry.
