DETAILED DESCRIPTION OF THE INVENTION

[0024] The space-saving multi-level garage of the present invention will hereinafter be described in accordance with the accompanying drawings.

[0025] As shown in FIGS. 1-3, a space-saving multi-level garage comprises a passage frame 1, a garage group 2, a longitudinal lifter 3, a transversely-movable stand 4, a lifting frame 5, and a control mechanism, and can be situated above vehicle roadways or near vehicle crossways according to demand.

[0026] The passage frame 1 permits vehicles to pass normally, the existing roadway is not destroyed, and the normal passage of vehicles is not influenced. Generally, the passage frame 1 comprises a plurality of standing columns and one or more ceiling plates fixedly supported by the standing columns. A plurality of groove shaped tracks is formed at the fitting portion on both the passage frame 1 and the lifter 3. Namely, the fitting portion between the passage frame 1 and the lifter 3 is the inner sides of the four standing columns.

[0027] The garage group 2 is fixedly located on the ceiling plates of the passage frame 1. The garage group 2 has a multi-storey structure, and generally comprises from 5 to 30 stories. Each storey comprises at least two garage units 21 serving to park the vehicles. In the present embodiment, each storey comprising four garage units is taken as an example. The size of each garage unit 21 is designed to fit for the size of a normal vehicle 6, e.g., a car.

[0028] Among the four garage units 21, the first garage unit 21 is laid side by side with the second garage unit 21' to form a first garage unit group, the third garage unit 21'' is laid side by side with the fourth garage unit 21''' to form a second garage unit group. The first garage unit group and the second garage unit group are located symmetrically back to back with respect to each other. Namely, the gate of the first garage unit 21 is opposite to that of the third garage unit 21', the gate of the second garage unit 21' is opposite to that of the fourth garage unit 21'''. An opening is formed between the first garage unit group and the second garage unit group and serves to accommodate the up-down movement of the lifter 3.

[0029] A second transverse travel path 22 is set in each garage unit 21. A vehicle bracket 23 to accommodate the vehicle is set inside of each garage unit 21. The position of the second transverse travel path 22 is lower than that of the vehicle bracket 23.

[0030] The vehicle bracket 23 has a L-shaped cross section, and is fixedly located symmetrically inside of the garage unit 21, the vertical plate of the bracket 23 is fixed, while the horizontal plate of the bracket 23 acts as the vehicle supporting plate; a plurality of open slots 231 is formed on the supporting plate to form two rows of vehicle bracket rods 232 (as shown in FIGS. 6-7).

[0031] A groove shaped track is formed on the opposite side edge lines of the four garage units 21 on each storey; the opposite side edge lines act as the fitting portion of the garage group 2.

[0032] As shown in FIGS. 3-7, the longitudinal lifter 3 is located inside of the garage group 2 and the passage frame 1, and is located in the opening of the garage group 2. The longitudinal lifter 3 comprises a motor 32, a reduction gear box 33, a chain wheel 34, a chain assembly and two cranes 31. The lowest position of the longitudinal lifter 3 is not higher than that of the roadway. The crane 31 is a flat plate; the first transverse travel path is set on the upper surface of the flat plate.

[0033] The motor 32, the reduction gear box 33, and the chain wheel 34 are disposed on top of the garage group 2. The chain wheel is disposed at the middle line of the top of the garage group 2. The middle line serves to connect transversely the first garage unit group and the second garage unit group. The motor drives the chain wheel to rotate via the reduction gear box. The chain wheel comprises four cross-distributed chain wheel assemblies.

[0034] The chain wheel drives the chain assembly wrapped on the chain wheel to move. The wrapping method of the chain assembly is shown in FIGS. 3-4. The chain assembly comprises a first chain assembly 351 and a second chain assembly 352.

[0035] The two cranes 31 are fixedly connected to the chains at the two sides of the chain wheel, respectively. The length of the chain between the two cranes is slightly greater than the height of the whole multi-level garage. The movement of the chain assembly drives the cranes 31 to move longitudinally. The chain assembly drives the left crane 31 to ascend, while the right crane 31 to descend; or alternatively, the chain assembly drives the right crane 31 to ascend, while the left crane 31 to descend.

[0036] The two cranes are located correspondingly between the first garage unit group and the second garage unit group. The first transverse travel path is set on each crane. The first transverse travel path located on the left crane can be butt connected with the second transverse travel path on the garage unit at the left side of the first garage unit group or the second garage unit group. The first transverse travel path located on the right crane can be butt connected with the second transverse travel path on the garage unit at the right side of the first garage unit group or the second garage unit group.

[0037] A plurality of idler wheels is disposed at the side edge line positions of the two cranes, and is fit for the groove shaped tracks. The side edge line position of the crane acts as the fitting portion of the crane.

[0038] The transversely-movable stand 4 can move between the lifter 3 and the garage unit 21. At least three motor-driven trolleys are set at the bottom of the transversely-movable stand 4. The transversely-movable stand 4 can move backwards and forwards on the first and second transverse travel paths. A notch is formed on the upper surface of the transversely-movable stand 4.

[0039] The lifting frame 5 comprises a lifting plate 51, a lifting arm 52, and a drive device (not shown in the figures), the lifting plate 51 is installed on top of the lifting arm 52. The drive device could be in a motor-driven up-down structure. The lifting plate 51 is designed to be a shaped structure (as shown in FIG. 7). The two side portions are designed to be a pair of supporting columns 511, and the middle portion acts as a connective section 512. The width of each supporting column 512 is slightly less than the distance between the two adjacent bracket rods 232 on the vehicle bracket 23. The width of the cross section of the connective section 512 and the lifting arm 52 is less than the distance between the two bracket rods 23, so that the lifting plate 51 can pass the vehicle bracket 23 up and down easily to fulfill the ascending or descending of the vehicle 6.

[0040] The lifting frame 5 and the vehicle bracket 23 are combined to form the lifting exchange device serving to put the vehicle onto the garage unit 21 or to bring the vehicle back from the garage unit 21.

[0041] The distance between the vehicle bracket and the second transverse travel path is greater than the distance between the first transverse travel path and the lifting frame when it descends to the lowest position, and is less than the distance between the first transverse travel path and the lifting frame when it ascends to the highest position.

[0042] The control mechanism serves to park or bring the vehicle back through the engagement of the longitudinal lifter 3, the transversely-movable stand 4, and the lifting exchange device.

[0043] Since the transversely-movable stand 4 and the lifting frame 5 installed on the transversely-movable stand 4 has a certain height, in order to drive the vehicle onto the lifting frame 5 easily, the following methods can be applied:

1) a pair of potholes to accommodate the longitudinal lifter 3 is formed on the ground, and the depth of the pothole is equal to the height of the transversely-movable stand 4 and the lifting frame 5 installed on the transversely-movable stand 4; a retractable plate is disposed on top of the potholes. When a vehicle travels normally, the plate is opened so that the vehicle can pass the plate normally; when a vehicle needs to be parked, the plate is closed. 2) alternatively, a retractable oblique plate 7 is set at the two sides of the cranes 31 of the longitudinal lifter 3 respectively. A slide slot 311 is formed at the two sides of the cranes 31, respectively. The upper end of the oblique plate 7 is fixedly on the crane 31 via a slide block 72. A supporting plate 71 is further bunched at the middle portion of the oblique plate 7. The other end of the supporting plate 71 is bunched on the crane 31. An idler wheel 72 is installed at the lower end of the oblique plate 7. As shown in FIG. 8A, when parking a vehicle, the longitudinal lifter 3 is descended to the ground oblique plate 7.

[0044] In accordance with the multi-level garage of the present invention, the vehicle is parked via the steps of:

a) descending the longitudinal lifter 3 to the ground, setting the oblique plate 7 down (as shown in FIG. 8A), then driving the vehicle to the lifting frame 5 on the transversely-movable stand 4 on the longitudinal lifter 3 via the oblique plate 7; b) driving the longitudinal lifter 3 to ascend via the motor, closing the oblique plate 7 (as shown in FIG. 8B), and sliding the slide block 72 down to a position under the line C; the longitudinal lifter 3 is driven to ascend to a height equaling to the height of a certain garage unit 21; c) controlling the drive device of the lifting frame 5 to ascend the lifting plate 51 and the lifting arm 52 to lift the vehicle; d) moving the transversely-movable stand 4 into the garage unit 21. At this moment, the lifting plate 51 moves with the transversely-movable stand 4 above the vehicle bracket 23 inside of the garage unit 21 to the desired location; e) stopping the movement of the transversely-movable stand 4, and controlling the drive device of the lifting frame 5 to descend the lifting plate 51 to a position below the vehicle bracket 23 so as to put the vehicle onto the vehicle bracket 23 to complete the exchange process; f) moving the transversely-movable stand 4 and the lifting frame 5 back to the longitudinal lifter 3; and g) returning the longitudinal lifter 3 to its original position.

[0045] In accordance with the multi-level garage of the present invention, the vehicle is brought back from a garage unit via the steps of:

a) driving the longitudinal lifter 3 via the motor to ascend to a height equaling to the height of a certain garage unit 21 parked with a vehicle; b) moving the transversely-movable stand 4 and the lifting bracket 5 into the garage unit 21. At this moment, the lifting plate 5 is located below the vehicle bracket 23; c) controlling the drive device of the lifting frame 5 to drive the lifting plate 51 ascending to pass through the vehicle bracket 23 to lift the vehicle so as to fulfill the vehicle exchange process; d) moving the transversely-movable stand 4 back to the longitudinal lifter 3, the lifting plate 51 moves with the transversely-movable stand 4 above the vehicle bracket 23 inside of the garage unit 21; e) descending the lifting frame 5; f) descending the longitudinal lifter 3 to its original position, and opening the oblique plate 7; and g) driving the vehicle away.
