To this end, when installing the rails on an uneven floor, a number of metal plates, etc. must be placed between the rails and the floor. Insert the rail so that it remains horizontal.

However, when multiple metal plates, etc. are overlapped and inserted between the rail and the floor, problems arise in making it difficult to accurately align the horizontal state of the rail, and also due to vibration or random external forces generated when the rack is running. A problem also occurred in which the inserted metal plate could move or come off arbitrarily.

Accordingly, in order to solve the problem of difficulty in maintaining the rails firmly after adjusting the horizontal state in the conventional mobile rack device as described above, the present applicant, through domestic patent application no. In the rail device provided on the floor of the installation site and on which rollers provided at the bottom of each rack travel, the rail is formed in the shape of a bar with a certain length, and a plurality of rails are installed extending along the longitudinal direction. , A rail connection member having a cross-sectional shape of "┗┛" is installed at the lower part of the point where the ends of a pair of rails meet each other, and a height adjustment member for adjusting the height between the floor surface and the rails is provided on the lower side of the rail connection member. An application has been filed for a ‘rail device for mobile racks,’ which is characterized as “installed and configured.”

At this time, the applicant's 'rail device for mobile rack' has fully implemented the purpose of maintaining the mobile rack rail firmly while efficiently leveling it, but can more easily control the horizontal state of the mobile rack rail with a simpler configuration. There is a need for an additional structure to maintain the system.
