Abstract

Lift and slide parking systems employ a plurality of novel trolley apparatus. Each trolley includes a rectangular frame from which a platform may be raised and lowered via cables coupled to lifting bars positioned at each of four corners of the platform. On one side of the frame a slide rail and trolley sliding assembly includes hydraulic cylinders coupled with cables routed through sheaves arranged to enable movement of the trolley horizontally a necessary distance. The slide rail may include grooves in which a sliding block may be slidably retained. On the side opposite the slide rail is a lift rail and platform lift assembly which includes a hydraulic cylinder coupled with one or more belts routed through rollers to a lifting block coupled with cables routed through sheaves and coupled to lifting bars arranged to enable vertical movement of the platform. The lift rail may include grooves in which a cylinder block and lift block are slidably retained. A sliding roller at each corner of the frame is positioned to engage in tracks attached to the superstructure which run the width of the parking system.

Dependent claims

A trolley for a lift-slide parking system, the trolley comprising a rectangular frame and a rectangular platform depending from the frame, wherein the frame comprises a first side comprising a lift rail comprising a platform lifting apparatus, a second, opposite side comprising a slide rail comprising a trolley sliding apparatus, and first and second ends disposed between the first side and opposite side, and further comprising at least one roller extending from each of the first and second end of the frame and oriented in axial alignment with the first and second ends of the frame, wherein the rollers at each end of the trolley are sized and configured to engage respective tracks oriented in axial alignment with the first and second ends of the frame, wherein the tracks are fixed to a superstructure of a lift-slide parking system, wherein the platform lifting apparatus comprises a lift hydraulic cylinder coupled to the lift rail disposed in axial alignment with the first side coupled to a cylinder block comprising a cylinder block sheave slidably disposed in a cylinder block channel formed in the lift rail in axial alignment with the cylinder, wherein the cylinder block is coupled via a belt to a first end of a lifting block slidably disposed in a lifting block channel formed in the lift rail side and axially aligned with and above the cylinder block channel, wherein the belt is routed over at least one roller positioned in a first corner of the frame in axial alignment with the lift rail, wherein the belt is anchored to the frame proximal the first corner and routed around the cylinder block sheave, wherein the lifting block comprises a plurality of lift cables extending from a second end thereof, wherein each of the plurality of cables extend and are coupled to respective lift bars coupled to respective corners of the platform;

and wherein the trolley sliding apparatus comprises at least two slide hydraulic cylinders coupled to the slide rail and disposed in axial alignment with the second side of the frame, wherein a first of the slide hydraulic cylinders is coupled to a first slide cable, wherein the first slide cable is anchored at a first end to the frame and couplable at a second end to one of the tracks at a first position, and a second of the slide hydraulic cylinders is coupled to a second slide cable, wherein the second slide cable is anchored at a first end to the frame and couplable at a second end to the same track as the first slide cable at a second position wherein when the first and second slide cables are coupled to the track, wherein actuation of one of the slide hydraulic cylinders is operable to pull the slide cable coupled thereto causing the trolley to move in a first direction in axial alignment with the track, and actuation of the other of the slide hydraulic cylinders is operable to pull the slide cable coupled thereto causing the trolley to move in a second, opposite direction.

A lift-slide parking system comprising a plurality of trolleys positioned within a superstructure, the superstructure comprising a front side and a rear side and a plurality of tracks oriented horizontally on the front and rear side, each of the trolleys comprising a rectangular frame and a rectangular platform depending from the frame, wherein the frame comprises a first side comprising a lift rail comprising a platform lifting apparatus, a second, opposite side comprising a slide rail comprising a trolley sliding apparatus, and first and second ends disposed between the first side and opposite side, and further comprising at least one roller extending from each of the first and second end of the frame and oriented in axial alignment with the first and second ends of the frame, wherein the rollers at each end of the trolley are sized and configured to engage respective tracks oriented in axial alignment with the first and second ends of the frame, wherein the platform lifting apparatus comprises a lift hydraulic cylinder coupled to the lift rail disposed in axial alignment with the first side coupled to a cylinder block comprising a cylinder block sheave slidably disposed in a cylinder block channel formed in the lift rail in axial alignment with the cylinder, wherein the cylinder block is coupled via a belt to a first end of a lifting block slidably disposed in a lifting block channel formed in the lift rail side and axially aligned with and above the cylinder block channel, wherein the belt is routed over at least one roller positioned in a first corner of the frame in axial alignment with the lift rail, wherein the belt is anchored to the frame proximal the first corner and routed around the cylinder block sheave, wherein the lifting block comprises a plurality of lift cables extending from a second end thereof, wherein each of the plurality of cables extend and are coupled to respective lift bars coupled to respective corners of the platform;

and wherein the trolley sliding apparatus comprises at least two slide hydraulic cylinders coupled to the slide rail and disposed in axial alignment with the second side of the frame, wherein a first of the slide hydraulic cylinders is coupled to a first slide cable, wherein the first slide cable is anchored at a first end to the frame and coupled at a second end to one of the tracks at a first position, and a second of the slide hydraulic cylinders is coupled to a second slide cable, wherein the second slide cable is anchored at a first end to the frame and coupled at a second end to the same track as the first slide cable at a second position, wherein actuation of one of the slide hydraulic cylinders is operable to pull the slide cable coupled thereto causing the trolley to move in a first direction in axial alignment with the track, and actuation of the other of the slide hydraulic cylinders is operable to pull the slide cable coupled thereto causing the trolley to move in a second, opposite direction.
