Description

Folding cart for vehicle loading {FOLDING CART}

The present invention relates to a folding cart that can be loaded on a vehicle with a patient, baggage, or various equipment loaded thereon, or can be moved out of the vehicle. Particularly, the rear leg provided in the loading unit is folded outward in a rearward state. It can be placed in the narrow space of the vehicle luggage compartment so that it can be located inside without protruding

When the cart is loaded into a vehicle luggage compartment, a front auxiliary caster that comes into close contact with the bottom of the luggage compartment is provided before the front leg of the loading unit is folded, so that the cart is transported into the luggage compartment while supporting the loading unit horizontally even when the front leg is folded. When more than half of the cart is transported into the luggage compartment, the rear legs that were supported on the ground must be folded. Even if the rear legs are folded, an intermediate auxiliary caster is provided on the bottom of the loading section to hold the loading section and keep it horizontal. When loading a cart into a luggage compartment, it relates to a folding cart for a vehicle that can be loaded directly into the luggage compartment by simply pushing it horizontally without having to lift the cart.

Carts for carrying patients, baggage, or other equipment and loading them in the luggage compartment of the vehicle are first folded in the rear when the vehicle is loaded, and then the rear legs are folded backward.

In this case, the rear leg folded backward is located out of the loading part (which is positioned protruded to the rear of the loading part), and for this purpose, there is a problem of designing a cart to fit the space of the vehicle luggage compartment.

For example, Korea Utility Model Registration No. 20-0268435 (2002.03.05, registered, hereinafter referred to as `` prior art 1 '') `` Improvement stretcher '' in front and rear close to the center of the mounting frame (corresponding to the loading part of the present invention) When the legs are installed and folded, they can be located in the loading section, preventing the rear legs from protruding behind the seat.

As can be seen in the drawing of the prior art 1, the center of gravity is biased toward one side or the center, which results in substantially narrowing the loading area of the seat because the center of gravity must be loaded to avoid the biased side,

In addition, as the height of the luggage compartment is higher, it is practically not practical to use the rear legs having proportionally corresponding lengths in order to be located closer to the center of the loading section.

In addition, the length of the front leg is called A, and the rear leg should have the same length as A ', and the total length of the front and rear legs is A + A'. There was a problem that the width should be equal to or larger than the total length of the front and rear legs.

Among the techniques to solve this problem,

Japanese Patent Application Laid-Open No. 5-31139 (published as `` Preceding Technology 2 '') `` DAMPING APPARATUS FOR STRETCHER IN AMBULANCE '' includes two arms each hinged to the frame, The other end of the arm is composed of a base that is hinged to each other is installed, the two arms folded on the basis of the hinge to the frame to move up and down,

The frame corresponds to a loading portion of the present invention, and the two arms and the base correspond to the front and rear legs of the present invention, while the prior art 2 allows the two arms and the base to be closely attached to the lower part of the frame without departing from the frame.

In order to load such a stretcher into a vehicle compartment (corresponding to an ambulance in the prior art 2), the frame has to be lifted and lifted by manpower or energy in the lowered state, and the same must be lifted and lowered when unloading.

Therefore, the applicant of the present invention can be folded in the rear of the front and rear legs, so as to be located in the loading portion can be loaded in the narrow space of the vehicle luggage compartment,

Instead of lifting by manpower, etc., it can be loaded into the car's luggage compartment by pushing it horizontally with only the pushing force in the state where there is an object to be loaded.

In addition, by moving the folded rear legs to the front legs to move forward, the cart can be miniaturized by having a front and rear width corresponding to or close to the length of the front legs.

The front and rear legs are interlocked with each other to fold together to escape from the structure that must be lifted and loaded when loading the vehicle luggage compartment,

When the front and rear legs are folded individually, the auxiliary auxiliary caster is further provided so that the front auxiliary caster comes into close contact with the floor of the vehicle luggage compartment before the front leg is folded and in this state is transferred to the vehicle luggage compartment. Through the structure that comes in close contact with the bottom of the vehicle luggage compartment, we developed a folding cart that can be pushed and loaded as it is.

According to the present invention, the rear legs arranged in the lower part of the loading part are in the same line as the folded front leg, and the rear legs arranged in the lower part of the loading part are slid to be hidden in the lower part of the loading part. By being located within the front and rear widths of the loading section (not protruding), it is an object to provide a folding cart for loading a vehicle whose space substantially occupies the vehicle storage compartment corresponds to the size of the loading section.

In addition, the present invention is to rotate the rear rear foot with the release of the fixing means to be located in the upper portion of the loading portion by rotating the rear leg to be located in the front and rear width of the loading portion, the space occupying substantially the vehicle luggage compartment is loaded It is an object to provide a folding cart for loading a vehicle corresponding to the size of a part.

Furthermore, the present invention is supported by the bottom of the luggage compartment even if the front leg of the load is folded to support the load, while the back leg supported on the ground is supported on the bottom of the luggage compartment is provided with an auxiliary caster on each corresponding portion to support the load It is an object of the present invention to provide a folding cart for loading a vehicle that can be loaded directly into the luggage compartment by simply pushing it horizontally without having to lift and load the load.

In addition, an object of the present invention is to provide a folding cart for loading a vehicle further comprising a rear auxiliary caster for assisting movement of the loading unit in a state in which both front and rear legs are folded.

In order to solve the above problems, an example vehicle folding cart according to the present invention,
