Abstract: 1,075,768. Mechanical storing devices; endless chain conveyers. MOBILE PARKING S.A. Sept. 22, 1964 [Oct. 16, 1963 (3)], No. 38607/64. Headings B8A and B8E. [Also in Division F2] A storing device, e.g. for parking vehicles comprises platforms 7, Fig: 1, endless chains connecting the platforms and consisting of telescopic links 19, 20 interconnected by links 25 and endless guides 3a; 3b in which the chains are guided. The device is located in a pit 1 having a concrete lining 2 in which are disposed the guides 3a 3b, Fig. 3. The platforms 7 have at the ends of their sides rollers 8 and at the centres of their sides rollers 6 and are dished to provide two parking spaces per platform, Fig. 4 (not shown), extending transversely of the latter. The pivots 18, Fig. 5, of the roller 6 form also pivots of adjacent telescopic links each comprising a cylinder 20 and a piston 22, the latter being provided with small bores 21 to provide resistance to the flow of oil with which the cylinder 20 is filled. Between the rollers 6 the chain is provided at the pivots 23 thereof with rollers 24. The guides 3a, 3b have side portions 26, 27 for receiving the rollers 6 and 24 and side portions 28, 29 for receiving the rollers 8. The chains are driven by mechanisms 30 comprising endless chains 35, Fig. 6, extending over sprockets 31, 32, one pivot pin of each chain 35 being laterally extended for pivotal connection to a piston red 36 which is reciprocable in an hydraulic cylinder 37, the latter being fixed to the side walls of the pit 1. The chains 35 engage lugs 39 on the telescopic links 19, 20. As shown in Fig. 1 the platforms 7 when disposed in the upper or lower parts of the device abut each other, the telescopic links 19, 20 interconnecting the abutting platforms being almost fully extended-and those at the sides of the device being compressed. In operation as a platform 7 leaves the upper part of the device to move to the lower part thereof its speed is increased. The succeeding platforms are braked by the telescopic links, the braking being determined by the movement of oil through the bores 21 in the pistons 22; a small vacuum may be produced behind the pistons 22 when the links 19, 20 are fully extended so that the platform 7 will move rapidly at the start of its movement. Valves may be provided to give greater resistance of oil movement when the links 19, 20 are being compressed than when they are being extended. The side portions 26, 27 and 28, 29 of the guides 3a, 3b may be straight. Separate guides may be provided for the rollers 6 and 24. The movement of the device may be controlled manually or automatically. The platforms 7 may be provided with roofs or may be replaced by compartments. The parking device may be a multistorey device. The rollers 6 may be omitted or the rollers 8 may be provided in different vertical planes at the centres of the sides of the platforms 7 with the rollers 6 at the ends of the sides. The driving mechanisms 30 may be replaced by means for driving the platforms 7 directly or the drive may be divided between the platforms and the endless chains. The upper and lower parts of the device may be inclined and the platforms maintained horizontal.
