Abstract

Automatic drive device for filing cabinets, which is specially designed for application in filing cabinets in which the drawers are arranged in such a way that their displacement is carried out according to a closed up and down circuit, always maintaining their horizontality and being of the same type. That the movement is produced by two lateral chains related to each other by means of a transverse axis endowed with a pair of extreme pinions for their engagement with such chains, one of them being motor and the other constituting a guide, and the movement reaching the motor chain through a transmission driven by a motor, while the support or supports of said drawers are formed by plates integral with the articulated joints, which form a series of plates hinged to the links of the chains, essentially characterized in that the ends of the plates that perform their articulation on the cited chains affect it in pairs, while the opposite or external ends are also articulated in pairs, belonging to the two plates articulated at this external point to two plates articulated in two contiguous points of the chains themselves, having been planned that in the external joints mentioned are the plates that constitute the supports for the drawers, with the particularity that on the side of the guide-chain a third chain parallel to it and at a slightly lower level is provided, whose third chain has the same angular articulations of plates, in such a way that between the angular articulation of each pair of associated plates gives the guide chain and the articulation of each pair of plates of said third chain is interposed a connecting rod joining each pair of joints mentioned.
