Abstract
A system for parking automobiles in a garage which uses a single-drive mechanism to simultaneously move automobile platforms. The automobile platforms reside in contiguous storage towers and are stacked in multiple levels. The automobile platforms simultaneously move in the towers. In one tower, the platforms move upward while the platforms in the other tower move downward. The automobile platforms rest on movement chains which move vertically among the various levels. The automobile platforms are moved from the vertical movement chains to a lateral movement means to move horizontally from tower to tower. The vertical movement system is powered by single-drive mechanism through a series of gears, sprockets and chains. Horizontal movement in the upper and lower lateral transfer areas is done by a lateral movement means.
Description




STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT




Not Applicable.




BACKGROUND OF THE INVENTION




1. The Field of the Invention




The present invention relates generally to parking garage elevator systems, and more particularly, but not entirely, to a parking garage system having simultaneously moving vehicle storage platforms.




2. Description of Related Art




Parking garage systems are useful because of the lack of parking space in urban areas. Parking garage systems are typically multi-level structures in which the automobiles are stored. Automobiles may travel from level to level by driving along an elevation ramp connecting the levels. Such multi-level garages increase the available parking space by providing the additional levels, thereby utilizing previously unused vertical space. However, the elevation ramp and drive-through lanes take up space.




Some parking garage systems have been developed to improve the multi-level garage concept by making it more compact. Some such systems utilize an elevator or other suitable lift system to move the automobile vertically to the desired level, and a separate moving platform or pallet to move the automobile horizontally into the desired parking space. Although such systems have indeed made multi-level parking garage designs more compact, the requirements of an elevator shaft (or series of elevator shafts) to contain the elevator or lifting means still takes up space that is rendered unusable for storing the vehicles. The elevator shafts are used to move the automobile vertically from level to level. Once the automobile arrives at a desired level, a movable platform or pallet is used to move the automobile horizontally from space to space. When all available storage spaces are used, the elevator shaft remains as unused space.




The prior art is characterized by garage systems that require a large amount of space for the operating equipment, and which is therefore not available for parking. The spaces used for elevator shafts or other lifting means take up valuable space that could be used for the storage of additional automobiles.




These and other disadvantages are addressed by the present invention. The present invention is, more efficient than the prior art designs in addressing the above-mentioned failures, and other problems, by utilizing the methods and structural features described herein.




BRIEF SUMMARY AND OBJECTS OF THE INVENTION




It is therefore an object of the present invention to provide a parking garage system that more efficiently utilizes the available space.




It is another object of the present invention, in accordance with one aspect thereof, to provide a parking garage system that is powered by a single-drive mechanism capable of powering two or more towers of simultaneously-moving automobile platforms.




It is a further object of the present invention, in accordance with one aspect thereof, to provide a parking garage system that allows automobiles to be stored in and retrieved from the system without the need for a separate elevator shaft in which the automobiles cannot be stored.




It is an additional object of the invention, in accordance with one aspect thereof, to provide a parking garage system having an array of storage platforms that operate to move in a circulating manner to allow automobiles to be loaded and unloaded from the system faster on the average than other automobile elevator systems.




The above objects and others not specifically recited are realized in a specific illustrative embodiment of a parking garage system having automobile storage platforms that move generally simultaneously and in a circulating manner. The apparatus includes a plurality of automobile storage platforms that are supported by a support structure and powered in a preferably vertical direction by a single-drive mechanism. The automobile platforms are equipped with traction mesh to prevent the automobiles from slipping when the system is in motion, and drip pans to contain fluids that might drip from the automobiles. The single-drive mechanism is driven by a power supply, which provides power to a series of sprocket gears through a drive gear in a reduction box. The sprocket gears turn a plurality of preferably vertical movement chains, which mesh with a series of support sprocket gears. The automobile platforms rest on pins attached to said movement chains.




The automobile platforms and support structures are preferably arranged in at least two storage towers having multiple levels, with said towers having a width that is preferably equivalent to (or slightly larger than) the automobile platforms. When the drive mechanism is engaged, the automobile platforms simultaneously moves upward in one storage tower and downward in the other storage tower. This simultaneous vertical movement allows one platform to be elevated to another level for storage while the platforms in the other tower will move downward toward ground level. A lateral movement means horizontally moves the platforms one at a time from one tower to the other preferably at the upper-most level, while a conveyer means laterally transfers the platforms one at a time in the lower storage area.




Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by the practice of the invention without undue experimentation. The objects and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION OF THE INVENTION




For the purposes of promoting an understanding of the principles in accordance with the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention claimed.




It is to be understood that this invention is not limited to the particular configurations, process steps, materials and features disclosed herein as such configurations, process steps, materials and features may vary somewhat. It is also to be understood that the terminology employed herein is used for the purpose of describing particular embodiments only and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims and equivalents thereof.




The publications and other reference materials referred to herein to describe the background of the invention and to provide additional detail regarding its practice are hereby incorporated by reference herein. The references discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as a suggestion or admission that the inventor is not entitled to antedate such disclosure by virtue of prior invention.




It must be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.




In describing and claiming the present invention, the following terminology will be used in accordance with the definitions set out below.




As used herein, “comprising,” “including,” “containing,” “characterized by,” and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional, unrecited elements or method steps.




As used herein, the term “vehicle”, and grammatical equivalents thereof, refers to any device used for transportation of an object from one location to another, whether the device is self-propelled or not. The term “vehicle” is intended to include, but is not limited to: any automobiles (including cars or trucks), water craft (including boats and barges), airplanes, motorcycles, all terrain vehicles, tractors, bicycles or other devices used for transportation.




Applicant has discovered that the space-saving benefits of a parking garage are greatly enhanced by a garage having side-by-side, contiguous storage sections or towers, without the need for an elevator shaft between the storage towers. This arrangement is rendered useable by providing a plurality of automobile support platforms that move simultaneously and circulate in sequence from one storage tower to another. By causing the automobile storage platforms to move simultaneously and in tandem with each other, in a circulating movement path, the need for a temporary displacement space, such as a central elevator shaft, is unnecessary.




Referring now to

FIG. 1

, there is shown a side view of a parking garage elevator system, designated generally at


10


. The system


10


includes a plurality of automobile platforms


20


. Traction pads


22


are preferably disposed on an upper surface of each platform


20


, for receiving the wheels of an automobile (not shown) thereupon. The traction pads


22


would inhibit any slipping of the automobiles during movement of the automobile platforms


20


. The automobile platforms


20


also contain a drip pan


24


to collect any fluids dripping off of a vehicle and to shield the automobile below from becoming soiled.





FIG. 1A

(a partial view of a platform


20


shown in

FIG. 1

) shows two downward-facing, preferably U-shaped, brackets


21


that attach to the two longitudinal edges of the automobile platform


20


and wherein said brackets


21


extend from the sides of the platform


20


, such that each platform


20


preferably carries four brackets


21


. Referring again to

FIG. 1

, the U-brackets


21


on the platforms


20


in the upward vertical storage tower


32




a


align with the upward vertical movement chains


26




a


. Similarly, the U-brackets


21


on the platforms


20


in the downward vertical storage tower


32




b


align with the downward vertical movement chains


26




b


in the downward vertical storage tower


32




b


.

FIG. 1B

(a close-up view of a section of the vertical movement chains


26


shown in

FIG. 1

) shows a pin


23


attached to a vertical movement chain


26


. Referring again to

FIG. 1

, the pins


23


are spaced such that the distance between them corresponds to the height of one level


27


of the parking garage system


10


. The storage levels


27


are preferably equivalent in height to one another.




The U-brackets


21


engage the pins


23


, which are attached to the upward and downward vertical movement, chains


26


, and allow the platforms


20


to rest on the pins


23


. The four vertical movement chains


26




a


in the upward moving storage tower


32




a


move simultaneously in an upward direction. As the upward vertical movement chains


26




a


move in an upward direction, the platforms


20


are caused to ascend upwardly within the upward moving storage tower


32




a


. Platforms


20


descend in the downward moving storage tower


32




b


as the downward vertical movement chains


26




b


move at; the same speed and at the same time in tandem with the upward vertical movement chains


26




a


. When a platform


20


reaches the upper lateral transfer area


30




a


of the upward moving storage tower


32




a


, a separate platform


20


in the downward moving storage tower


32




b


simultaneously reaches the lower lateral transfer area


36




b


. Vertical movement of the vertical movement chains


26


stops when a platform


20


reaches a lateral transfer area


36




b


or


30




a


in the appropriate storage tower


32


, responsible to any suitable sensing and stopping means known to those of ordinary skill in the art. Said platforms


20


are now in position to move laterally to the other storage tower


32


.




In one embodiment, horizontal movement in the upper lateral transfer area


30




a-b


is accomplished with L-shaped swing arms


64


. The L-shaped swing arms


64


are attached to a lateral movement means


72


with a hinge


70


. The lateral movement means


72


has a sleeve


73


that is slidably circumscribed around the support structure


52


. Referring to

FIG. 1A

, the automobile platforms


20


may have four slots


62


formed therein, two of which are preferably located on each of the bottom longitudinal edges of said platform


20


. These slots


62


receive the bottom portion


64




b


of L-shaped swing arms


64


as shown in

FIG. 1C

(a partial view showing a side view of the swing arm


64


depicted in FIG.


1


).




Referring again to

FIG. 1

, the L-shaped swing arms


64


preferably robotically swing into position with the bottom portion


64




b


of the swing arm


64


fitting in to the four slots


62


of the platform


20


, in any suitable manner known to those skilled in the field of robotics or other movement mechanics. The four swing arms


64


preferably swing on a hinge


70


. The hinge


70


is attached to a lateral movement means


72


. The lateral movement means


72


functions to move said platform


20


laterally to the downward storage tower


32




b


. The lateral movement means


72


preferably first lifts the platform


20


until the platform


20


is high enough to clear the pins


23


attached to the vertical movement chains


26


. (Alternatively, spring-pivot U brackets


25


of

FIG. 6A

could be used in lieu of brackets


21


, to eliminate the need to lift the platform. The lateral movement means


72


then is caused to slide along the support structure


52


in any suitable manner known to those of ordinary skill in the field, to thereby laterally transfer the platform


20


from the upward storage tower


30




a


to the downward moving storage tower


32




b


. The lateral movement means


72


then lowers the platform


20


until the U-brackets


21


rest on the pins


23


(see

FIG. 1B

) attached to the downward vertical movement chains


26




b


in the downward storage tower


32




b


. After the platform


20


is lowered onto the pins


23


, the swing arms


64


are caused in any suitable manner to swing in an upward direction and out of the path of the platform


20


. The lateral movement means


72


then returns to its original position in the upward moving storage tower


32




a


until the next platform


20


is raised into the upper lateral transfer area


30




a.






The platform


20


in the downward moving storage tower


32




b


then descends in said tower


32




b


on the downward moving vertical chains


26




b


until a platform


20


reaches the lower lateral transfer area


36




b


. Any suitable conveyance means, such as two conveyer belts


28


, preferably span the lower lateral transfer area


36




b


. As the platform


20


lowers, the bottom of said platform


20


comes in contact with and rests upon the conveyer belts


28


. The downward vertical movement chains


26




b


continue downward and the pins


23


attached to said chains


26




b


descend below the platform


20


, and the chains


26




a


and


26




b


are caused to stop responsive to any suitable sensing and stopping means. The conveyer belts


28


laterally transfer the platform


20


to the upward moving storage tower


32




a


, in simultaneous tandem with the lateral transfer of a platform


20


in the upper lateral transfer area


30




a-b.

It will be appreciated that the structure and apparatus disclosed herein is merely one example of a lateral movement means


72


, and it should be appreciated that any structure, apparatus or system for lateral movement which performs functions the same as, or equivalent to, those disclosed herein are intended to fall within the scope of a means for lateral movement, including those structures, apparatus or systems for lateral movement which are presently known, or which may become available in the future. Anything which accomplished functions that are the same as, or equivalently to, a means for lateral movement falls within the scope of this element.





FIG. 5

shows an alternative embodiment of the parking garage elevator system of FIG.


1


. The features and workings of this alternate embodiment include the same elements (not shown) as the system


10


in FIG.


1


. The difference in this alternate embodiment is the orientation and means for horizontal movement. In this embodiment, the system stores the automobiles horizontally rather than vertically, and horizontal movement of the platforms


20


is accomplished with any suitable alternative embodiment of a means for horizontal movement that could occur to one of ordinary skill in the relevant art having possession of this disclosure.




Referring now to

FIG. 6

, a top view of the alternative embodiment of a means for horizontal movement is shown. The alternative embodiment for the horizontal movement means shown in

FIG. 6

has the same elements and reference numerals as the embodiment for the garage system


10


in

FIGS. 1-4

, with the exception of the alterative means for horizontal movement. Platform


20




c


is shown in the upper lateral transfer area


30




b


of the upward vertical storage tower


32




a


, while platform


20




d


is in the downward vertical storage tower


32




b


, one level below the upper lateral transfer area


30




b


. In this embodiment, spring pivot U-brackets


25


are attached to the platform


20


.




The platforms


20


do not need to be raised above the pins


23


for lateral movement. Referring to

FIG. 6A

(a close-up view of the spring pivot U-brackets


25


as shown in FIG.


6


), the spring pivot U-brackets


25


may pivot back and forth by operation of a spring pivot hinge


27


(or its functional equivalent) which allows the U-bracket


25


to pivot. This spring pivot hinge


27


allows the platform


20


to slide off of the pins


23


without the need to lift the platform


20


over the pins


23


. The brackets


25


simply pivot responsive to contact with the pins


23


when the platform


20


is moved in a lateral direction.




Referring again to

FIG. 6

, as the platform


20


moves laterally, the pin


23


on the vertical movement chain


26




a


causes the spring pivot U-bracket


25


to pivot. As the platform


20


continues to move laterally, the spring pivot U-bracket


25


releases the pin


23


and pivots back to its original position by operation of the spring pivot hinge


27


. As the platform


20


laterally moves to the next storage tower


32


, the spring pivot U-bracket


25


on the platform


20


pivots as said bracket


25


comes in contact with the pin


23


on the vertical movement chain


26




b


. Once the center of the spring pivot U-bracket


25


is above the pin


23


, the spring pivot U-bracket


25


pivots back to its original position as is now surrounding the pin


23


. This engagement of the pins


23


and spring pivot U-brackets


25


occurs substantially simultaneously with all four spring pivot U-brackets


25


attached to said platform


20


. The platform


20


is now resting on the vertical movement chains


26


and is in position to move vertically.




In the embodiment shown in

FIG. 6

, horizontal movement of the platforms


20


is accomplished with idler wheels


100


and horizontal movement chains


102


. The idlers


100


and horizontal movement chain sprockets


104


are attached to a shaft


106


. The shaft


106


is attached to a beam


108


, which is movably attached to the support structure


52


in a manner than allows the beams


108


to pivot.




Referring now to

FIG. 7A

, a close up side view of the alternative embodiment of a means for horizontal movement shown in

FIG. 6

, as a platform


20


arrives in the lateral transfer area


30




b


, the beams


108


pivot and any suitable locking means


112


locks the beams


108


in place. This motion (indicated with arrows) allows the rollers


100


to swing upward and into contact with the platform


20


. The horizontal movement chains


102


also swing upward and mesa with teeth


110


attached to the lower side of the platform


20


. The horizontal movement chains


102


are then caused by drive sprockets

It will be appreciated that the structure and apparatus disclosed herein are merely examples of a parking garage elevator system


10


, and it should be appreciated that any structure, apparatus or system for a simultaneous parking garage system which performs functions the same as, or equivalent to, those disclosed herein are intended to fall within the scope of a means for said simultaneous parking garage system, including those structures, apparatus or systems for said simultaneous parking garage system which are presently known. Anything which functions the same as, or equivalently to, a means for said simultaneous parking garage system falls within the scope of this element.




In accordance with the features and combinations described above, a preferred method of the simultaneous parking garage system


10


includes:




(a) a parking garage system


10


comprising two vertical storage towers


32


consisting of multiple levels


27


;




(b) automobile platforms


20


transported vertically by movement chains


26


;




(c) an upper lateral transfer area


30


consisting of idlers


100


and horizontal movement chains


102


; and




(d) a lower lateral transfer area


36


consisting of idlers


100


and horizontal movement chains


102


.




It will be appreciated that the simultaneous parking garage system


10


provides a parking garage that efficiently utilizes the space. The simultaneous movement of the automobile platforms


20


provided by the vertical movement chains


26


alleviates the need for elevator shafts. This provides more space for the parking of automobiles because there is no space in the system dedicated for an elevator shaft.




The simultaneous movement of the automobile platforms


20


also simplifies the process of loading and unloading automobiles from the system. This is most beneficial when a car needs to be unloaded. In some conventional parking garage systems, retrieval of an automobile requires the movement of other automobiles to gain access to the automobile that needs to leave the system. The present invention allows an automobile to exit the system without re-arranging other automobiles. The system merely has to circulate until the desired automobile platform


20


is at an exit level. Either lower-level position


90




a


(

FIG. 4

) may be used as an entry or exit. Alternatively, the system


10


may be partially subterranean, if by example ground level is at


92


(FIG.


4


), in which case position


90




b


could function as an entry or exit.




The simultaneous system also makes loading and unloading faster because the user does not have to wait for an elevator to go up and come back down before the next automobile is loaded or unloaded. The reversibility of the system also decreases the time required to load and unload. Any suitable enhancement may also be added. For example, removable wheel blocks may be placed about a wheel of a stored vehicle to prevent it from rolling forward. Any suitable means for temporarily preventing movement of the car on the platform is within the scope of invention.




It should be appreciated to one skilled in the art that the present invention is not limited in scope to the storage of vehicles. The elevator system and storage platforms could be configured and arranged to store any object.




It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements. Thus, while the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment(s) of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made without departing from the principles and concepts set forth herein,
