Abstract

A double-deck parking device is provided for parking two cars one above the other in order to more efficiently utilize available parking space. The parking device includes a platform which may be moved to a position adjacent a base plate for locating a vehicle thereon. The platform may be raised above the base plate and another vehicle may be parked on the base plate. The platform may be further raised to a vertical position to allow vehicles of differing heights to be mounted on the base plate thus accommodating differing vehicle heights.

Claims5

Dependent claims

A double-deck parking device comprising:

(a) a substantially rectangular base plate having a pair of opposing longitudinally extending end sections and a pair of opposing transversely extending end sections;
(b) a pair of longitudinally spaced apart support members, each of said support members fixedly coupled to said base plate at a respective longitudinal end section adjacent one of said transversely extending end sections;
(c) a pair of lifting arm assemblies respectively coupled in pivotal relation to each of said support members, each of said lifting arm assemblies including a front arm member and a rear arm member pivotally connected to a respective support member on a first end of each of said front and rear arm members, a lifting arm member pivotally coupled to said front and rear arm members at a second end thereof, and a connecting frame extending in said longitudinal direction coupled to said longitudinally displaced opposing front arm members, each of said support members, front and rear arm members and lifting arm members defining a four bar linkage;
(d) a pair of drive mechanisms for rotatively displacing each of said lifting arm assemblies with respect to a respective support member, each of said drive mechanisms including a screw rod having an upper end secured to said connecting frame, a hydraulic cylinder coupled to said screw rod for actuation thereof, said hydraulic cylinder being secured to a respective rear arm member and driven by a reversible motor;
(e) a platform supported on said connecting frame, said platform having substantially the same rectangular contour as said base plate, wherein actuation of said drive mechanisms provides for displacement of said platform (1) to a position above said base plate for providing a parking base for a vehicle above said base plate;
(2) to a position transversely adjacent said base plate for loading a vehicle thereon, and (3) to a position wherein said platform extends substantially in a vertical direction to allow vehicles of varying height to be mounted on said base plate.

(c) a pair of lifting arm assemblies respectively coupled in pivotal relation to each of said support members, each of said lifting arm assemblies including a front arm member and a rear arm member pivotally connected to a respective support member on a first end of each of said front and rear arm members, a lifting arm member pivotally coupled to said front and rear arm members at a second end thereof, and a connecting frame extending in said longitudinal direction coupled to said longitudinally displaced opposing front arm members, each of said support members, front and rear arm members and lifting arm members defining a four bar linkage;
(d) a pair of drive mechanisms for rotatively displacing each of said lifting arm assemblies with respect to a respective support member, each of said drive mechanisms including a screw rod having an upper end secured to said connecting frame, a hydraulic cylinder coupled to said screw rod for actuation thereof, said hydraulic cylinder being secured to a respective rear arm member and driven by a reversible motor;
(e) a platform supported on said connecting frame, said platform having substantially the same rectangular contour as said base plate, wherein actuation of said drive mechanisms provides for displacement of said platform (1) to a position above said base plate for providing a parking base for a vehicle above said base plate;
(2) to a position transversely adjacent said base plate for loading a vehicle thereon, and (3) to a position wherein said platform extends substantially in a vertical direction to allow vehicles of varying height to be mounted on said base plate.
