Description

The assembly type pallet}

The present invention relates to a prefabricated pallet, and more specifically, to a prefabricated pallet that can be stacked in multiple stages while reducing the volume of the pallet by sequentially folding the left and right frames and the front and rear frames without interference between them. .

As is well known, pallets are used to load and transport multiple items, and are used in a variety of ways throughout the industry.

The types of pallets are divided into plate type and box type depending on their shape.

The former, plate-type pallet, is constructed by installing brackets to secure parts on a floor frame without using side walls. This plate-type pallet is designed to be suitable for loading large parts, especially vehicles manufactured in the form of semi-finished products.

The latter, a box-type pallet, is built vertically on top of multiple floor frames and is made up of side walls that form the four sides of the pallet, making it suitable for loading small parts.

On the other hand, the box-type pallet described above has the disadvantage of exposing many problems during storage and transportation compared to the plate-type pallet because the volume of the pallet increases due to the side walls.

A representative prior art related to a box-type pallet is the Republic of Korea Intellectual Property Office Patent No. 10-1611095 (laminated connection unit of folding pallet).

The prior art includes a base frame, a vertical frame installed vertically at the outer edge of the base frame, and a horizontal frame positioned in a horizontally lying state between the vertical frames, and both ends of which are connected and fixed to the vertical frame with a connecting bracket. In the foldable pallet composed of a frame, a support frame having a length corresponding to the foldable pallet and having a cross-section formed to have a "ㄷ" shape is welded and fixed to the bottom of the base frame, and an upward support frame is attached to the bottom end of the support frame. a locking piece that is bent vertically, a fixing frame accommodated inside both ends of the support frame, and a plurality of pieces are formed on the bottom surface of the fixing frame at a predetermined distance apart from each other, and the locking pieces of the support frame are selectively fastened to the fixing frame. A connection unit is installed to connect and secure two foldable pallets stacked upwards and downwards, which are made of the same structure and consist of fastening slots for connecting and fixing the frame to the support frame and holes formed between the fastening slots, and the fixing unit is installed. A protrusion protruding from the upper surface of a connecting bracket provided on a foldable pallet disposed below the foldable pallet is inserted into the hole of the frame, and is configured to connect and fix two foldable pallets stacked upward and downward.

However, conventional folding pallets, such as prior art, are partially welded in many places on the pallet in order to achieve quick productivity and eliminate inconvenience in use. This welding work causes a lot of inconvenience when the pallet is later separated and reused. give.

Additionally, in the prior art, the vertical and horizontal frames do not have a structure that can be folded in half, so when removing various items contained in a pallet, the height of the vertical and horizontal frames may cause damage to the items before separating the vertical and horizontal frames from the base frame. Since withdrawal operations are not possible, there is a lot of inconvenience in using it.
