7 Cla'uns. (Cl. 214-16.1)

This invention relates to parking devices for automobiles, and the like, and for storing the same, and has particular reference to an elevator-type mechanism having a plurality of cages or the like, onto which the automobiles are driven to be elevated for storing and which may be lowered to the surface to be driven therefrom.

This invention has for its principal purpose an irnproved, simple, smooth, efcient and trouble-free operation of an elevator or endless conveyor type of automobile parking, whether inside or outside of a building. It may be utilized to park as great a number of cars on a given floor or ground area as any construction now known or existent, with a more rapid parking and release from parking than any other construction now known or existent.

The apparatus may be constructed in units, to which more units may be added, both sideways and lengthwise and to any height that parking conditions may require.

For illustration: In a construction of seven units lengthwise and five units sideways, thirty-tive cars can be parked at the same time by merely stopping the car on the lowermost cages and the same number of cars can be released from parking at the same time by merely getting into cars and driving out in forward motion. Both parking and release from parking can be repeated in short spaces of time until the construction is either filled or vacated. It is to be noted that to maintain a trouble-free operation, a number of the parts have been duplicated and the construction is such that repairs or replacements may be made with the last possible delay and without hindrance to the parking and delivery of cars in the units.

Each unit will be separately operated by reversible motors and so electrically connected to a single panel board in a convenient location so that any car or cage may be brought to any desired position, either clockwise or counterclockwise, whichever is desired, by pressing a button on the board.

This construction further provides a dual automatic compensation for expansion and contraction of materials used and for wear and tear of moving parts so the car cage platforms will always rest firmly on the iloor, whereby cars can be driven on and off from a solid` base.

Furthermore in the assemblage of any number of units of this construction, there is provided a passage or walkway so that a driver or owner can always depart after parking and return to his car to leave parking with safety from the moving parts of other units.

The principal object of the invention, therefore, is to provide a mechanism for elevating and storing of automobiles having automatic means for compensating for expansion and contraction and for eliminating wear of the elevating or moving parts.

Other objects of the present invention are to provide a frame mechanism for supporting and rotating an elevating mechanism; to provide motors mounted on a frame structure at the upper portion thereof'for raising and lowering the cages in which the automobiles are housed;

to provide means for removably fastening the carriages to the lifting chains of the mechanism; to provide means in the elevating mechanism whereby the tension will remain substantially constant on the elevating mechanism;

5 to provide means on the cages for contacting the framework structure for guiding the cages therealong; to provide cages with means for resiliently mounting the platforms therein; to provide the platform of the cages with corrugations or the like to prevent rolling of the automobiles therefrom; to provide means for lowering a cage to the surface of the oor of the building or parking space so that the vehicle may be driven directly onto the cages or off from the cages as desired, and to provide means for moving the cages from one column of the framework structure to the other and maintaining the cages in upright position.

In accomplishing these and other objects of the invention, I have provided improved details of structures, the preferred form of which is illustrated in the accompanying drawings wherein:

Fig. l is a vertical cross-sectional View of one unit of the invention showing the cages attached to the rotating mechanism with one of the cages in lowered position and the corner uprights of two abutting units side by side and the passageways for pedestrians.

Fig. 2 is a vertical cross-sectional view from the side of' the device particularly illustrating the floating shaft for compensating for expansion and contraction and wear on the chains and the shafts across the top carrying gears for operating the elevating mechanism.

Fig. 3 is a perspective view of one of the cages illustrating the corner posts and connection to the elevating chains and the rollers at the four corners of the platform of the cage for engaging the frame when being elevated or lowered and aetingas a running gear for the cage when contacting oor.

Fig. 4 is an enlarged cross-sectional View of one of the corner posts of the cages particularly illustrating the resilient mounting of the platform thereon for the purpose of recompensation of the movement of the platform when the cage is lowered to the floor.

Fig. 5 is an enlarged cross-sectional View of apparatus for attaching the cages to the elevating chains.

As stated above, the structure of this device is particularly adapted to compensate for expansion, contraction, and wear of the elevating parts, and particularly the lower shaft having bearings in sliding movement for compensation for the expansion and contraction of the chain links and the resilient mounting of the corner posts of the carriage so that when the rollers on the carriage contact the floor, as shown in Fig. l, the resilient mounting will also compensate for the length of the rotating chains to additionally assure that the loading platform will always be constantly on the surface of the garage or parking space.

Referring more in detail to the drawings:

1 designates a parking or storage elevator embodying the improvements of this invention comprising corner posts or

columns

2 and 3. While I have hereillustrated only one column for the elevating of cars, it will be obvious that any number of columns may be constructed side by each, or end to end, as desired. Each column will be referred to as a unit. `The

posts

2 and 3 constitute the side posts of one unit, which may be aflixed in a suitable manner to the posts 4 and 5 of an adjoining unit. These posts or columns are oifset at their respective lower corners of the framework structure as indicated at 6 and 7, as best illustrated in Fig. l, and mounted on a base or loading surface 8.

It will be noted that the enlarged portions provide

runways

9 and 9 to provide a safeplace for the custorners or drivers of the automobiles` to walk through the 3 structure to the place of entry to their automobile, or when emerging therefrom to go through such runways to the outside of the parking area.

The framework structure consists of a plurality of horizontal rails 1t), 11, and 12, although any number may be used, depending on the height of the structure, and a cross head 13 is provided at the top of the structure. Mounted upon the horizontal rail and spaced inwardly from the

posts

2 and 3 are vertical standards or the like, 14 and 14. These standards may be placed between each of the horizontal rails as desired. Bearings 16 and 17 are mounted upon the vertical standards 14 and 14' and bearings 18 and 19 are mounted on the

posts

2 and 3 for accommodating short shafts 21D and 21, on which are mounted

gears

22 and 23.

Gears

27 and 28 are mounted on the

shafts

26 and 26 and mesh with

worms

29 and 30, having connection with gear reduction boxes 31 and 31', operated from

motors

32 and 33, mounted upon the upper portions of the framework structure in a suitable manner, and also meshing with the

gears

22 and 23.

Also mounted upon the shafts and 21 are

sprockets

34, 35, 36, and 37, respectively, for accommo-dating pairs of link chains, or the like, 38, 39, 4t), and 41, respectively.

The lower end of the

chains

38, 39, 40, and 41 operate over pairs of sprockets 42, 43, 44, and 45, mounted upon a shaft 46 having its ends engaging in bearings 47 and 48, which in turn are slidably engaged in

bearings

49 and 49 secured to the frame

upright posts

2 and 3 and horizontal beam 12, so as to provide for vertical sliding movement of the shaft 46 to compensate for eX- pansion and contraction of the chains running over the sprockets.

The sprockets are provided with teeth 50 over which the

endless chains

38, 39 and 40-41 run at the respective upper and lower portions of the framework structure. The chains are composed of links 51, assembled with pins 52-53, as is the usual practice. At spaced intervals the chains pivotally mount a plurality of cages 54 through a sleeve ridge pole or rod 55. It is understood that the links are provided with what is known as blind and open link parts, through which the sleeved ridge pole of the cage is extended. The pole 55 is connected to the blind portion of the links by set screws or the like 56 and the poles are removably connected therein so that each individual cage may be removed for repair or otherwise as desired without disassembling the elevating mechanism.

Each cage comprises a platform or base 57 having

runways

58 and 58 for the wheels 59 of an automobile 61), the runways being corrugated as indicated at 61 to prevent the automobiles from rolling therefrom without power should the brakes become loosened. The platform comprises

side rails

62 and 63, provided with

rollers

64, 65, 66 and 67 at each corner of the platform. Mounted on the

side rail

62 and 63 are upright

tubular members

68, 69, 70 and 71.

Substantially U-shaped

tubular members

72 and 73 have their respective free ends telescoped in the

tubular members

68, 69, 70 and 71, respectively, with the curved upper portions secured to the ridge pole 55 through

suitable bearings

74 and 75 welded or otherwise suitably secured to the underside of the upper portions of the U-shaped member, as best illustrated in Fig. 3. The free ends of the

tubular members

72 and 73 are provided with aligned slots as indicated at 76 (Fig. 4) and the

tubular members

64, 65, 66, and 67, have aligned

openings

78 and 79 adapted to receive a pin or bolt 80 to telescopingly mount the respectively tubular members together. The lower ends of the

tubular members

72 and 73 are closed as indicated at 81, Fig. 4, and a coil spring 82 engages against the end 81 and against the

side rails

62 or 63 of the platform, so that when the

rollers

64, 65, 66 and 67 Contact the surface of the garage, pressure will be exerted 4 on the spring 82 to recompensate for expansion and contraction of the chain elevating mechanism.

The ridge pole 55 comprises two

rods

82 and 83 extending through the

bearings

74 and 75 respectively and are sleeved into a tubular member 84. The outer ends of the rods are secured in the links 51 by the set screws 56. The ends of the

rods

82 and 83 are spaced apart in the tubular member 84 and are held by set screws or the like, 85 and 86, so that when it is desired to remove a cage from the assembly, the set screws 56 and 555 and 86 may be loosened and the

rods

82 and 83 may slide therein and through the

bearings

74 and 75 to remove the ridge pole from the chains without dismantling the chains.

The rollers also perform the function of contacting the surface or lloor of the base structure 8 of the garage or parking area immediately upon the cage descending thereto to provide a running gear for the cage and a firm base for the automobile to be driven onto and off of the platform of the cage.

Secured to the respective cross members 1t), 11, and 12 of the framework structure by suitable means and running transversely thereof, are beams or

members

87, 88, and 89, and mounted thereon are

inner guide members

90 and 91, as best illustrated in Fig. l. The respective ends of the guide members are turned slightly inwardly, as indicated at 92 and 93. Also secured to the side posts 2 and 3 are

outer guide members

94 and 95.

The

rollers

64, 65, 66, and 67, respectively, engage the

guide members

90, 91, 94, and 95, respectively, for guiding of the cages in their path of travel upwardly and downwardly in the column as best illustrated in Fig. l and prevent sidewise tipping of the cages during the ascending or descending movement.

It will be obvious the lower shaft 46 is suspended in the

bearings

49 and 49 through the sprocket and chain arrangement from the upper shafts 20 and 21. In the event there should be expansion or contraction in the chain elevating structure, this will be compensated for through the sliding bearings arrangement of the lower shaft 46, and when the cage approaches the oor, the rollers will contact the same and rotation of the chain will carry the cage with the automobile thereon to the lowermost position shown in Fig. 1 so that the car may be removed therefrom. The spring loaded tubular members of the cage will automatically recompensate for the expansion and contraction of the elevating mechanism so that the platform of the cage will always remain liush with the surface of the parking area or garage floor.

It will be obvious that the

motors

32 and 33 through the rear gear reduction box and worm gears 29 and 30 meshing with the

gears

27 and 28, which in turn meshes with the sprockets will rotate the cage structure including the chain links to elevate and lower the cages as desired.

Operation of a device constructed and assembled as described is as follows:

The cage 54 is placed in the lowermost position on the surface 84 of the garage and an automobile, or the like, driven directly onto the platform of the cage by the attendant or by the owner. The

motors

32 and 33 are then energized through suitable control means (not shown), to operate the gears and the sprockets to drive the

shafts

20 and 21 and 26, causing the chains to rotate on the sprockets to move the cages carrying the automobile either in a clockwise or anti-clockwise direction, one of the principal features of my invention being to provide a structure wherein one automobile parked part way up on the left-hand side of the column may be lowered therefrom, instead of going over the top and down the opposite side, as is the usual practice. Upon descent of the cage to the door, the automobile is driven from the platform as desired.

It will be obvious that the cages may be stopped at any position in the structure, or reversed, at the will of the operator. When the owner calls for his car, the attendant will lower the cage to the bottom position in the shortest direction to the surface of the garage.

It will be obvious that my structure may be built to any desired height or as many columns, side by each, or end to end, as desired, and it will also be obvious that the owners of the automobiles may enter the structure and move from their automobiles or return thereto through the runways without danger from moving structures.

It will be obvious from the foregoing that I have provided an improved, simple, ecient, and trouble-free operation of an elevator construction for parking and storage of automobiles or the like.
