18 Sheets-Sheet 1 5 STORAGE PALLETS AND DRIVE MEANS THEREOF This invention relates to a horizontal circulation type of storage equipment having a plurality of horizontal rows of pallets for carrying an article, especially an automotive vehicle, on each pallet in which the pallets are arranged in a manner to provide a vacancy, at one end of each of the pallet rows so that successive and alternate transfer of pallets in their longitudinal direction (hereinafter to be referred to as longitudinal transfer) and in their lateral direction (hereinafter to be referred to as lateral transfer) in a manner to fill up such vacancies can move a desired article carrying pallet to a predetermined station. More specifically, this invention relates to a storage equipment of the type described having efficient drive means for causing the longitudinal and lateral transfer of pallets, lift means for use with such equipment, and coupling means for coupling the pallets in the form of a train. This invention further relates to a pluralstoried storage equipment comprising a stack of such storage equipments.
Vehicle parking apparatus of merry-go-round type, elevator type, elevator crane type and other types have heretofore been proposed in the art and put into practical use. However, all these prior vehicle parking apparatus have been defective in that they are expensive due to complex structure and have a low degree of space availability, that is, a great deal of dead spaces are involved therein. They have been further defective in that they have a low degree of safety in operation in view of their mechanism and a large power requirement is inevitable with such apparatus.
In an effort to eliminate these and other defects of the prior parking apparatus, a horizontal circulation type of vehicle storage equipment has been recently proposed which has a plurality of horizontal rows of pallets for carrying an automative vehicle on each pallet and in which the pallets are arranged in a manner to provide a vacancy at one end of each of the pallet rows so that successive and alternate transfer of pallets in their longitudinal and lateral directions, that is, longitudinal and lateral transfer in a manner to fill up the vacancies can move a desired vehicle carrying pallet to a predetermined station. While this horizontal circulation type of storage equipment has had excellent effects of eliminating the defects involved in the prior parking apparatus as described above, it has been still insufficient in its operation and there has been a demand for improvements in the structure and operation of this type of equipment.
It is the primary object of the present invention to provide lateral transfer and longitudinal transfer means preferably used with such horizontal circulation type of storage equipment.
Another object of the invention is to provide pallet shifting means preferably used with a case in which the vehicle entrance is disposed at a position remote from the pallet rows.
A further object of the invention is to provide suitable means for providing communication between floor stages when such horizontal circulation type of storage equipments are stacked up to have a plurality of stories.
Another object of the invention is to provide means for coupling the pallets in the form of a train.
These and other objects of the present invention will become apparent from the following description with reference to the accompanying drawings:

Referring to FIG. 1, there is shown the basic principle of the horizontal circulation type of vehicle storage equipment in which it will be seen that vacancies corresponding to two pallet are provided at symmetrical ends of two horizontally arranged pallet rows and the pallets are successively and alternately transferred in their lateral direction as shown in FIG. 1A and in their longitudinal direction as shown in FIG. IB so that a desired pallet can be brought to a predetermined station.
At first, drive means for the lateral transfer will be described with reference to FIGS. 2 to 4. Vehicle carrying pallets l are arranged two horizontally parallel rows with eight pallets in each row, for example, as shown in FIGS. 2 to 4 and any two comer positions at symmetrical ends of the two pallet rows are
