Abstract
Abstract A device for parking automobiles comprises two interconnected superimposed platforms which may be lifted and tilted to provide ground level access to either platform and fixed rail tracks and guideways on each side of the platforms. One of the trackways is fixed and the other is connected to the platforms which themselves co-operate with a fixed guide element.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A device for parking automobile vehicles comprising: an upper and a lower platform; means to support said platforms in vertical spaced relationship; means to raise and lower both of said platforms between a lower, horizontal position and an upper, tilted position; a pair of substantially rectilinear coordinated trackways disposed laterally at each side of said platforms and extending substantially alongside each other when said platforms are in a lowered position to define an acute angle therebetween when viewed from the side, said pair of trackways on each side of the platform extend beneath said upper platform in both the raised and lowered positions; a first one of each pair of coordinated trackways being fixed; a second one of each pair of coordinated trackways being connected to said platforms and movable therewith; and guide elements cooperatively engaging said trackways; one of said guide elements being a fixed guide element cooperatively engaging each second trackway.
Claim 2
Independent Claim
153 words
A device for parking automobile vehicles comprising: an upper and a lower platform; means to support said platforms in vertical spaced relationship; means to raise and lower both of said platforms between a lower, horizontal position and an upper, tilted position; a pair of substantially rectilinear coordinated trackways disposed laterally at each side of said platforms and extending substantially alongside each other when said platforms are in a lowered position to define an acute angle therebetween when viewed from the side, said pair of trackways on each side of the platform extend beneath said upper platform in both the raised and lowered positions; a first one of each pair of coordinated trackways being fixed; a second one of each pair of coordinated trackways being connected to said platforms and movable therewith; and guide elements cooperatively engaging said trackways; one of said guide elements being a fixed guide element cooperatively engaging each second trackway.
Claim 3
Dependent Claim
18 words
A parking device as claimed in claim 1, wherein said guide elements are in the form of rollers.
Claim 4
Dependent Claim
28 words
A parking device as claimed in claim 1, wherein said second one of each pair of trackways connected to the platforms comprises means to couple the platforms together.
Claim 5
Dependent Claim
38 words
A parking device as claimed in claim 1, wherein each fixed trackway is disposed upright and has an upper end and a fixed guide element is disposed in the area of said upper end of each fixed trackway.
Claim 6
Dependent Claim
43 words
A parking device as claimed in claim 4 wherein, each fixed guide element is positioned relative to the respective fixed trackway so that as said platforms are raised each second trackway and said platforms are gradually tilted with respect to their lowered positions.
Claim 7
Dependent Claim
70 words
A parking device as claimed in claim 5 further comprising a base frame, and wherein, each fixed trackway is supported on said base frame, and said means to raise and lower said platforms comprises hydraulic lifting cylinder means pivotally connected to one of said platforms and to said base frame in a relative position with respect to said trackways and guide elements to support said platforms in a raised position.
Claim 8
Dependent Claim
19 words
A parking device as claimed in claim 6 wherein said lifting cylinder is pivotally connected to said upper platform.
