- 2. Description of the Prior Art
- A conventional assembled pallet made of plastic, as disclosed in Taiwan patent No. 281912, is provided with plural plates and plural blocks used as feet and to support the plates.
- The conventional pallet is prepared at first by forming the plates and the blocks independently. Then, the plates and the blocks are mutually assembled together by manual labor to become a conventional pallet. The combination between the plates and the blocks is depended on locking rods on the top and the bottom of the block to fit in locking holes on the outer corners of the upper and the lower plates. That is, the combination of the plates with the blocks only counts on the engagement of the locking rods and the locking holes. Therefore, unless the plates and the blocks are made of materials with a considerable strength, otherwise a pallet assembled by the plates and the blocks does not have enough strength, easy to be broken.
- The objective of this invention is to offer a pallet provided with plural bases and a pallet plate that are formed together integrally, quickly manufactured and uneasy to be separated into parts or broken.
- The main characteristics of the invention are described as follows:
- 1. The pallet is provided with plural pallet bases respectively formed integrally and having a cylinder. The cylinder is provided with a connecting member at one end possessing an annular portion that is provided with plural projections and penetrating holes in both its top and its bottom surfaces respectively. The projections and the penetrating holes can be arrayed symmetrically or asymmetrically or evenly or unevenly.
- 2. The pallet base is provided with an engaging member at the other end that has to be set only for a double-layer pallet.
- 3. The pallet base can be formed as any shape as long as it is able to be matched with the pallet plate.
- 4. The pallet plate or the upper pallet plate of a double-layer is formed together integrally with the pallet bases, able to enhance the combined strength of the invention.
- 5. If the pallet plate is double-layered, the lower pallet plate is formed independently and then, combined together with the pallet bases.
