MULTI-STORIED GARAGE The present application corresponds to Japanese patent application No. 44/71091 filed on Sept. 8, 1969, from which the benefit of priority under the Paris Convention is claimed.
The present invention relates to a multi-storied garage.
Known multi-storied garages, such as those of the invention disclosed in the Japanese official patent gazette No. 36/3918, have been loaded with motor-vehicles by a lift cage which ascends and descends in a lift passage. This lift cage has been constructed to accommodate a single motor-vehicle, and has probably raised no problem when a plurality of storage chambers are provided only vertically, but when a plurality of chambers must also be provided on same floor levels, many lift cages are necessary in proportion to the number of chambers. Accordingly many entrances proportionate to the number of the lift cages must be provided, so that the greater part of the space on the floor where entrances are provided (usually the first floor) is occupied with the entrances, and there is no space to have chambers. After all, the conventional mechanical garages have had the common problem of the waste of land.
The garage of the invention disclosed in the Japanese official patent bulletin No. 36/3918 has arms operated by a hydraulic device to hold the bumpers of the vehicle in order to station it on the cart. By this method it is able to support the vehicles surely, but on the other hand, means to fix them on the cart is extremely comlicated and expensive.
Accordingly, it is an object of the present invention to provide a new and improved multi-storied garage in which conveyance of a vehicle mounted ona cart from a reception floor to each parking chamber can be fully automatically effected, said garage having a lift cage of a considerably larger size wherein a cart is lingitudinally movably arranged so that much more chambers can be installed, thereby avoiding the disadvantages of the conventional systems.
These and other objects, features and advantages of the present invention may be best understood by way of the following description of the exemplary apparatus employing the principles of the invention as illustrated in the accompanying drawings, in which:

slidably to the movable shafts 62, on the tips of which are formed flanges 68. Compression springs 69 are provided between said flanges 68 and the flanges 66 of the movable shafts 62.
Hooks 70 are attached to said flanges 68 of the slide cylinders 67. Said hooks are formed in the middle thereof with bosses 71 and connected by a pin 72 wheels 83 is rotatably fitted to bearing stands 82 placed on the right side of floor of lift cage 2, and driven chain wheels 85 are rotatably fitted to bearing stands 84 placed on the'left side of the floor of lift cage 2. Endless chains 86 provided with arms 87 connects said driving chain wheels 83 with driven chainwheels 85. The parts are so located that, with the movement of the endless chains 86, the tip 88 of one of the arms 87 enters the space between the rods 19 of the pair providedat one end of the bed plate 15 of the cart 4, thereby shifting the cart 4 transversely as the arm contacts the leading pin of the associated pair. A reversible motor 89 is supported at a suitable place in the lift cage, such as on the upper comer, and is connected to the driven pulley 91 of said driving shaft 81 by belt 90.- In FIG. 10 there is shown an automatic stop device 9 comprising a lever 92 pivotably fitted to a portion of inner wall 93 of the chamber, the tip 96 of said lever 92 projects into the lift passage 3 when it is attracted by electromagnet 95. Switch rod 97 pivoted on said tip 96 is arranged to open or close a switch 98. I
A red having a weight 102 which is attracted by an electromagnet 101 provided on a portion of inner wall is arranged by a stopper 103 to move vertically. 104 indicates an L-shaped stop lever pivotally attached to said portion of inner wall 100,-the lower end 106 of which is linked at 107 to a lower end of said rod 99, and the upper end of which is brought into contact with the underside of the floor of the lift cage 2 to stop its lowering. Each chamber (01) through (02) is provided with switch 109 which is adapted to actuate an the stop rod 104 to its initial position. A switch 110 fixedatthebottompartlll oftheliftcage2isarranged to operate the motor 89 or lift cage 2. A stopper 112 for a cart is provided in each chamber (a1) through (c2).
The operation of the preferred embodiments will be explained in detail. First, attention is directed to the clamp device 10, when a motor vehicle C is loaded on the cart 4 situated on the table 12 in the lift cage 2. The vehicle C is moved along the parallel guide rails 45 which are constructed on the bed plate 15. The wheels W of the motor vehicle C go forward along the guide rails, urging outwardly the L-shaped levers 38, each of which is attached with a tension spring 41, and are pressed by pinch portions 39, so that said vehicle is secured and fixed on said cart 4. In this way, the clamp device makes it possible to shift the vehicle safely with the cart 4. In the present invention, it is easy to draw out the motor vehicle C from the bed plate of the cart 4, if an external force which surpasses the tensile force of the spring 41 is given.
The moving device 13 for the table 12 will be described. The transmission shaft 25 is rotated by the operation of the driving motor 24 through the driving pulley 27, the belt 28 and the intermediate pulley 26. Along with the rotation of said transmission shaft 25, the screw rods 23 are rotated through the bevel gears 29 and 22, so that the moving bodies 34 are moved by the screw motion of the screw rods 23, thereby, moving forwards the table 12 and the cart 4 connected to said moving bodies 34 by the supporting rods 33 and the compression springs 35. When the table 12 contacts the stopper plates 36, a limit switch (not shown) causes the driving motor 24 to stop, whereby the motion of the screw rods 23 and the table 12 comes to a stop.
In this case the screw rods 23 continue to rotate because of the inertia, so that the moving bodies 34 further move. But the springs 35 provided between said moving bodies 34 and the supporting plates 32 eventually cause the inertia of said screw rods to vanish.
Practical operation of endless chain device 80 which shifts the cart 4 to the right to enter the chamber (a2) will be described with reference to FIG. 10. Upon stopping of the lift cage 2, the closing of the switch 110 fixed at the bottom part of said lift cage 2 by the tip 108 of the stop rod 104 will initiate the rotation of motor 89 so that the driving chain wheels 83 engaged with driving shaft 81 start rotating to advance the chains in the direction of arrow P by the belt 90. Accordingly the tip 88 of one of the driving arms 87 provided on the endless chains 86 enters and is locked between the rods 19 of the pair at the left end of the cart 4, so that said cart4 is shifted by the arm 87 into the desired chamber (to the direction of arrow P) along the guide rails 47. The parts are so arranged that stopper 112 stops cart 4 in a position at which arm 87 disengages the pin 19 against which it was pushing as illustrated in dotted lines in FIG. 10.
Removal of the cart 4 from the chamber to the table 12 is effected by the reverse rotation of said motor 89, so that the arm 87 of one of the endless chains 86 starts traveling in the direction of arrow Q to enter between the pair of pins 19 adjacent to the lift passage 3 and engages and advances a pin and the cart 4 to return the cart to its initial position upon the table 12.
To shift the cart 4 from table 12 to the chamber on the left as viewed in FIG. 10 when required is effected in the reverse manner, i.e. by operating chains 86 to advance arm 87 to enter between the pair of pins located at the right in FIG. 10. Said motor 89 is operated to start rotation not only by closing of the switch 110 but by the coupling operation of said switch and a controlling switch (not shown).
The clamp device 11A for the cart 4 provided in each chamber (a1) through (02) will be described with reference to FIG. 7. When the cart 4 is shifted from the lift cage 2 to the floor F of the chamber as described in the foregoing, the locking wheels 18 attached on the reverse side of the bed plate 15 are forced into between the pinch levers 58 and pinched by said pinch levers 58 fastened tightly by the tension springs 56, so that the cart 4 is kept in its position on the floor F of the chamber. Carrying the cart 4 out of the chamber when required is easily effected by giving the cart 4 an external force large enough to disengage the locking wheels 18 from the pinch levers 58.
The clamp device 11 for the cart 4 provided on the table 12 will be described. As explained in the foregoing, the cart 4 is shifted from the floor F of the chamber onto the table 12, then the locking wheels 18 attached on the reverse side of the bed plate 15 are caused to rotate along the pinch levers 49 or 50 and secured tightly by the tension springs 56 in positions where said pinch levers 49 and 50 meet, so that the cart 4 having said locking wheels in the reverse side, is held in position on the table 12. It is easy to draw out the cart 4 from the table 12, by giving an external force large enough to disengage the locking wheels 18 from the levers 49 and 50. v
Another embodiment of the clamp device 11A provided in the chamber (a1) through (c2) willnow be described with reference to FIG. 8.
When the cart 4 is shifted from the table 12 into the chamber, the member 79 attached on the reverse side of said cart 4 runs into the open locking portions 74 of the hooks so that the movable shafts 62, the base portions 63 of which are pivotably fitted by the pins 65, are caused to rotate. As the movable shafts 62 get nearer to the center-to-center line of the support plates 64, the slide cylinders 67 move outwardly against the force of the compression springs 69, and as the movable shafts 62 get farther from said line after passing it, the slide cylinders 67 urged inwardly by force of the compression springs 69, so that the hooks 70 pivot about pin 72. The books 73 move toward each other until they abut against the stoppers 75 and 76 respectively, and latch the member 79 of the cart 4. The stop portion 77 formed at the boss 71 of one hook 70 abuts against the regulating plate 78 and stops the movable shafts 62. Thus the cart 4 is secured in its position in the chamber. To carry said cart 4 secured by the clamp device 11A out of the chamber can be easily performed by giving a sufficiently large external force for moving the movable shafts 62 in the reverse direction against the force of the compression springs 69.
The practical operation for taking a motor vehicle C into a desired chamber will be described. For carrying the motor vehicle C into the chamber (al) on the highest floor from the entrance E on the first floor, suppose now, to make the explanation short, that the lift cage 2 stays on the highest floor; first, the cart 4 is carried out from the chamber (01) by the operation of the endless chain device 80 onto the table 12 in the lift cage 2 and is locked by the clamp device 11. In this case, the lift cage 2 must be raised a little and disengaged from the lever 104. Closing the control switch (not shown) causes the motor M to rotate reversely and energizes the electrornagnet 101 of the automatic stop the lower end of the rod 99 protrudes from its position shown in a broken line Y in FIG. into the lift passage 3, asshown inthe drawing. Therefore after the motor M stops operating, said stop rod 104 supports the bottom part 111 of the lift cage 2 which descends a little because ofthe looseness of the wire 5 and maintains the floor ofthe table 12 at just the same level as the floor of the entrance. g
.Then,'the motor vehicle C is shifted in the foregoing way onto the table 4 in t he lift cage 2and is held in position by the clamp device 10. And after that, the control-switch again makes the motor M rotate in the normal direction and energizes the electromagnet 95 of the automatic stop device 9. Then, the lift cage 2 carrying the cart 4 is raised in the-lift passage by winding up the wire 5, and the tip 96 of the lever 92 is pushed upwards by the protective device 8 against dropping of thelift cage2 as shown in a broken line in FIG. 10, whereby the switch 98 is closed by the switch lever 97. By this switch action the operation of the motor M of said lifting device 6 is stopped, the electromagnet 95 is deenergized and at the same time the electromagnet 101 is energized.Accordingly, in the'same way as mentioned before, the stop lever 104 ispivoted to support the bottom part 111 ofthe lift cage 2 so as to maintain the table 12 on the same level as the floor of the chamber (a1). With supportingsaid bottom part 111,
v the lever 104 also closes the switch 110 in order to make the endless chain device 80 operate, so that the cart 4 on the table 12 is moved into the chamber (a1) with the vehicle C locked safely on the table 12.
The foregoing explanation has been made by example of the chamber (al) which is located at the nearer side to the entrance E. When amotor vehicle must be shifted to the chamber (al') or.'(a2") on the farther the foregoing sequence of operation to carry the vehicle C into the chamber.
The operation for taking out a vehicle mounted on a cart 4 from the chamber (a2) when the empty lift cage 2 stays on the first floor, will be described. First, the motor 89 provided in the lift cage 2 is caused to rotate in the reverse direction v by the control switch, the motor M for the lifting gear 6 is rotated in the nomral direction and the electromagnet 95 for the chamber is energized, whereby the lift cage 2 rises as high as the chamber. At this moment, the lever 92, the switch 98, the electromagnet 101 and the stop lever 104 are actuated or energized in their order, to stop the lift cage 2,
the bottom part 111 of which is supported by the stop lever 104 which closes the switch 1 10. Accordingly, the endless chain device 80 is operated to shift the cart 4 loaded with the vehicleC out of the chamber, and once the cart is secured on the table 12 by the clamp device 11, the lift cage 2 is raised a little by the rotation of the motor M and the electromagnet 101 of the automatic stop device 9 is deenergized, so that the stop lever 104 returns to its position indicated by a broken line Y in FIG. 10 and said lift cage 2 lowers to the entrance E by virtue of the reverse rotation of the motor M, whereupon taking the vehicle C out of the multi-storied garage 8 is completed. It is desirable to deoelerate the rotation of the motor M so as to reduce the speed for winding or rewinding of the wire 5 just before the lift cage 2 stops movmg.
It will be understood that I vides a multi-storied garage for storing a number of vehicles C on difl'erent floor levels in'a'lir'nited area of land safely, surely and automatically, wherein it is assured that there is no rolling or falling of vehicles as they are held on the carts 4 latched by the clamp devices 11 and 11A on the table l2 or injthe chambers while descending or ascending in the lift passage 3.]
Moreover, the multi storied garage of the present invention can house motor vehicles C, not only in chambers (a1) through (02) adjacentito the entrance but also in chambers (01') through (c2)- beyondsaid chambers (a1) through (c2),by comprising a lifi cage which has the length covering all chambers provided 7 ing a multiplicate number of chambers which a single lift cage 2 can serve and load with vehicles.
It is understood that various changes and modifications may be made in the embodiments illustrated and described herein without departing from the scopeof the invention as determined by the following claims.
