Definitions

  • the invention relates generally to lifts or elevators which permit the vertical stacked parking of autonobiles. Specifically, the invention relates to such lifts which are powered by one or both of the driving, or traction, wheels of the automobile itself. More particularly, rotation of the driving wheels is used to pressurize the working fluid in a hydraulic system which includes a fluid accumulator in the control circuit regulating operation of the lift.
  • the lift can be configured with two rollers, a friction roller and a support roller, positioned atop the vehicle support platform to be engaged by the driving wheels.
  • a series of cables which, through the use of pulleys attached to lif t frame, can raise an d lower the platfor m .
  • the lift can also be selectively configured with rack and pinion or bevel gearing and lead screw as sem blies as desired so that the lift is powered according to the forward and reverse rotation of the friction and support rollers.
  • the lift described in Korean application 89-2417 can be configured with a hydraulic lift system wherein the friction and support rollers drive
  • the lift described in Korean application 89-2417 can be configured with a hydraulic lift system wherein the friction and support rollers drive an oil pump which powers a hydraulic cylinder assembly to raise and lower the platform. Pressure generated by the oil pump powers the cylinder to raise the platform and a relief valve is open to lower it.
  • the inventor endeavored to remove all imperfections from the design by submitting the system to rigorous testing, particularly with regard to load stability during liftin g operation s, and then modifying the system design in accordance with the finding s of these tests.
  • s ob served during testing was that harnessing of only one of the vehicle's driving wheels to power the platform lifting device was sufficient to raise the platform.
  • use of a single driving wheel served to significantly stabilize the load.
  • the present invention was developed with the foregoing problem s in mind.
  • the weight which the lift's operating mechanism has to elevate is significantly reduced by locating the major and heavier components of the operatin g mechanism off the elevating platform, and making the platform it self of reduced-weight construction.
  • Other weight-reduction features include the use of a single set of rollers driven by one traction wheel of the vehicle.
  • Althou gh the operator mu st ride up with the vehicle during initial parkin g in one em bodiment of the invention, it is not necessary for the operator to later regain acces s to the platfor m to lower it to the base position. Instead, a relief valve allows the operator to lower the platform from ground level by use of the system controls.
  • An alternative embodiment of the invention eliminates the necessity of the operator remaining with the vehicle while it is being lifted to the elevated parking position.
  • the invention comprises a lift for an elevated parking system which is operated by an accumulator device which harnesses the power of the vehicle being parked.
  • an accumulator device which harnesses the power of the vehicle being parked.
  • the system transfers power from the vehicle's driving wheels to a lift device which raises and lowers the load platform.
  • a wheel stopper device on the side opposite the driving wheel being utilized which functions to hold the vehicle securely atop the platform during lifting operations.
  • the lift is a practical, convenient, energy- and space-saving system which, because of its compact, self-contained design, permits multiple units to be grouped together for further increased parking capacity.

  • rollers 26 There are known devices which can be used to transmit the rotation of the roller s 26 to operate the pump 28, so that further description is not necessary. While both rollers 26 have been described as being con ⁇ nected to power the pu mp, if desired only one of the rollers may be so u sed, with the remainin g roller bein g freely rotatable to support the driving wheel.

  • Operation of the controller 46 directs pressurized fluid from the accumulator 44 into the cylinders 34, extending the rams 36 and moving the attached bars 38 to the rig ht (in Fig. 1). In this position, the controller 46 blocks fluid flow to the tank 30. Movement of the ram 36 in this manner draws up the cables 40, 41 to lift the platform 20 and the vehicle thereon. With the platform 20 at the desired elevation, the controller 46 is operated to stop further flow of pressurized fluid to the cylinders 34, and the rams 36 remain extended to maintain the platform elevated.

  • Operation of the controls 146 admits pressurized fluid into the cylinder 136, extending the ram 138 to raise the support bar 140. Raising of the support bar 140 lift s the cros s mem ber 122 and thus elevates the platform 111 and the vehicle thereon. Thereafter, another vehicle can be parked beneath the elevated vehicle.

Abstract

Un système destiné au parking par élévation de véhicules utilise un ascenseur (10, 110) entraîné par les roues motrices du vehicule (C). Ledit ascenseur comprend une plate-forme (20) de support de véhicule qu'élève et abaisse un mécanisme hydraulique (34, 36, 38; 136, 138, 140) actionné par un accumulateur (44; 144) qu'alimente en fluide sous pression une pompe (28, 132) actionnée par le véhicule. L'utilisation de l'accumulateur permet le fonctionnement de l'ascenseur sans qu'il soit nécessaire qu'un opérateur dans le véhicule commande l'élévation de la plate-forme. Les principaux composants du mécanisme hydraulique sont situés à l'extérieur de la plate-forme de manière à réduire le poids du système à élever. Dans un mode d'exécution préféré, une seule roue motrice (W) du vehicule (C) est utilisée pour actionner la pompe (28; 132) et l'autre roue est immobilisée. Chaque unité d'élévation est autonome et modulaire et il est possible d'assembler des unités multiples en vue d'accroître la capacité de parking.
