The present invention relates to a two-stage parking facility, and more particularly, using the rotational force of the wheel of the vehicle as a power source for operating the parking facility, the rotational force of the wheel to operate only the lifting unit of the parking facility, the left and right of the vehicle The movement is made by manual and relates to a two-stage parking facility in which a portion on which the vehicle is seated is formed by a plate accessible by the vehicle in front and rear.

The conventional two-stage parking facility is constructed so that a vehicle can be parked in two stages by seating a vehicle on a movable plate that can be elevated on four columns. However, such a conventional parking facility requires a separate power source to elevate the movable plate, which is not only expensive, but also requires a lot of space for installation because the four pillars continue to occupy the space once installed. do.

In recent years, there are many vehicles in one house, but it is not easy to install such a conventional two-stage parking facility in a residential neighborhood.

In order to solve this problem, the applicant has filed Korean Patent Application No. 10-2001-44074 dated July 18, 2001, the invention "two-stage parking equipment". In Korean Patent Application No. 10-2001-44074, a two-stage parking facility is composed of a rectangular upper frame and a lower frame, and the front and rear ends of the upper frame and the lower frame are connected by a lifting unit, which is a folding expansion and contracting device. A pair of screws were installed horizontally across each of the first half and the second half of the upper and lower frames, and a pair of hollow park cylinders, which were horizontally engaged with each other, were installed on the outer circumferential surface of each screw.

One end of the screw is fixed to the movable bracket which is slidably formed on one side of the upper frame, and the hollow cylinder part is placed on the movable bracket which is slidably formed on the other side of the upper frame.

Support plates are fixed to the other ends of the pair of hollow park barrels, respectively, and the outer surface of the support plate is formed with a caster for supporting and moving the hollow park barrel and the support plate on the ground during horizontal movement of the hollow park barrel. In addition, a screw nut engaged with each of the screws is fitted into one end of the hollow park cylinder portion, and a torque limit clutch is interposed between the hollow park cylinder portion and the screw nut, respectively. In addition, each support plate is attached to a bevel gear box for rotating the rotational force of the hollow tube cylinder 90 °, the power transmission shaft is connected between each bevel gear box of the front and rear half of the upper and lower frames.

A second reducer connected to the first reducer is fixed to one side wall of the lower frame by a power transmission shaft, and one end of one of the screws is connected to the first reducer of the lower frame. Further, a power transmission shaft is connected between the first reducers located in the middle of each of the front and rear half of the lower frame. In each of the second reducers, an output shaft protrudes in parallel to the front and rear ends of the lower frame, and at one end of the lower end of the elevating unit, a screw nut is formed to engage with the output shaft and move left and right as the output shaft rotates.

A chamfer is formed at one end of the hollow park barrel, and a torsion spring is installed at the hinge point to contact the chamfer of the hollow park barrel while forming a movement preventing bearing at one end of the curved lever hinged to the lower frame. In addition, the other end of the curved lever was installed in contact with the screw nut so that the movement preventing bearing is separated from the chamfer when the screw nut is completely moved to the right side.

Korean Patent Application No. 10-2001-44074 is a driving source that is configured to horizontally move left and right on the side of the upper and lower frames of the hollow park cylinder on which the wheel of the vehicle is seated, and to operate the parking facility by using the rotational force of the wheel of the vehicle. As it is used, the vehicle moves in a straight line at the rear side of the parking equipment, rests on the park section, and then moves to the parking position by simply rotating the wheels. In this case, the upper frame is lifted and moved to the parking position by the above operation. Therefore, there is no need for a separate power source to operate the parking equipment, and since there are no conventional four pillars, the entire parking equipment can be built vertically, thus reducing the space occupied by the parking equipment when not in use. .

However, in spite of these advantages, Korean Patent Application No. 10-2001-44074 is configured to allow the vehicle to move left and right as the wheel rotates the hollow park barrel and the screw nut in the hollow park barrel moves on the screw. Not only does it take a lot of time for the vehicle to move from side to side, and screw and screw nuts are expensive and the assembly work is complicated, thereby increasing the manufacturing cost.

In order to cope with the difference between the gaps, the screw and hollow cylinder are installed on the movable bracket which is slidably formed on the side of the rectangular frame, and at the same time in the middle of the power transmission shaft between the bevel gearboxes and between the reducers. Since the spacing device had to be installed for each, there is a problem of increasing parts.

In addition, Korean Patent Application No. 10-2001-44074 discloses that when two vehicles are parked in two stages on the stacked upper frame and the lower frame, the vehicle on the lower frame is completely removed from the parking facility in order to discharge the vehicle on the upper frame. There was a problem that the withdrawal process was cumbersome because it had to be removed.

An object of the present invention is to solve the above problems, and the upper and lower portions on which the vehicle is mounted are formed of a plate upper plate and a lower plate so that the vehicle is accessible from the front and rear and simultaneously the vehicle entered is supported on the entire upper surface.

At the point where the pinch rolls 11 and 11 and the hollow park cylinder part 12 are positioned at both sides of the bracket 122, the bearing 122a is installed after drilling.

Support shafts 11a are formed at both ends of the pinch roll 11, and support shafts 12a and 12b are formed at both ends of the hollow park barrel 12, and are formed at the left end of the hollow park barrel 12. The support shaft 12a is a hollow park cylinder type.

The pinch rolls 11 and the support shafts 11a, 12a, 12b of the hollow park cylinder part 12 are fitted in the bearing 122a of the bracket 122.

As shown in FIG. 5, the pair of pinch rolls 11 and 11 are spaced apart from each other such that the lower part of the vehicle wheel is seated without touching the hollow park cylinder 12.

2 to 4, each end of the polygon rods 13, 13 is connected to a vertical power transmission means.

As a means for operating the lifting unit (130, 130), the vertical power transmission means installed on one side of the lower plate 120, the first reducer (31, 31), the power transmission shaft (32, 32) and the second reducer (33) , And the second reduction gears 33 and 33 are fixed to the support bracket 124 protruding from one side of the lifting unit 130. Preferably, the first reducers 31 and 31 are bevel gear reducers, and the second reducers 33 and 33 are worm gear reducers. Each end of the polygon rods 13, 13 is connected to a first reducer 31, 31.

In addition, the first reduction gears 31 and 31 are connected to the second reduction gears 33 and 33 by the power transmission shafts 32 and 32 toward the front and rear ends of the lower plate 120, respectively. As shown in FIG. 9, the screw output shafts 34 and 34 protrude in parallel with the front-rear end of the lower support part 135 of the elevating parts 130 and 130 in each of the 2nd speed reducers 33 and 33. As shown in FIG. .

A power transmission shaft 35 is connected between the first speed reducer 31 positioned in the middle of the first half of the lower plate 120 and the first speed reducer 31 positioned in the middle of the second half of the lower plate 120 to raise and lower portions 130 and 130 at the rear end of the lower plate. Drive them simultaneously.

In FIG. 1, the first and second reduction gears 31 and 33 and the power transmission shafts 32 and 35 are spaced apart from the lower plate 120 for convenience of illustration, but the components are shown in the lower plate 120. It may also be located closely at.

As shown in FIGS. 8 and 9, the lifting unit 130 connects both ends of the two rods 136 and 136 connected to the hinge 137 by the hinge 137 to respectively support the upper and lower supports 135 and 135 is connected to the front and rear ends, the hinge 137 on one side is fixed to one side of the upper and lower support (135, 135) and the hinge 137 on the other side to be installed on the other side of the support (135, 135) As the patch type stretching apparatus, grooves 138 and 138 are formed on the other side of the upper and lower support members 135 and 135 in the lateral direction, respectively. The projections 137a of the hinge 137 on the other side are slidably inserted into the grooves 136 and 136.

A screw nut 131 is formed at the other hinge 137 into which the protrusion 137a is inserted into the lower groove 138, and the screw nut 131 is engaged with the screw output shaft 34 so that the screw output shaft 34 rotates. Move left and right. As shown in FIGS. 10 and 11, when the screw nut 131 moves to the right side, the top plate 110 is raised while the rod 136 is extended, and when the screw nut 131 moves to the left side, the rod ( The upper plate 110 is lowered while the 136 is folded. Since the first reducer 31 and the second reducer 33 are formed with bevel gears and worm gears, respectively, the rotational force can be increased by reducing the rotational speed of the polygonal rod 13, and only by the rotation of the polygonal rod 13. It will be appreciated that the upper plate 110 carrying the vehicle can be elevated.

As shown in detail in FIG. 6 and FIG. 7, the polygonal rod 13 is tightly and slidably fitted into the hollow park barrel 12 having a polygonal inner circumferential surface to engage the hollow park barrel 12. The torque limit clutch 14 is interposed in the left and right ends of the hollow park cylinder part 12. Therefore, as the wheel W of the vehicle seated on the hollow park barrel 12 rotates, the pinch roll 11 rotates and the hollow park barrel 12 rotates accordingly, and thus the rotation force of the hollow park barrel 12 is rotated. The polygon rod 13 is transmitted to rotate the polygon rod 13.

When the polygon rod 13 continues to rotate to move the screw nut 131 of the elevating portion 30 to the right as far as possible and the top plate 110 is fully raised, the polygon rod 13 can no longer rotate. At this time, if the wheel (W) of the vehicle is further rotated, any component of the lift drive means will be damaged, but in the present invention, the torque limit clutch ( Since 14) is interposed, even when the wheel (W) rotates in a state where the upper plate 110 is completely raised, the hollow park barrel 12 is idle, and the components of the lift drive means are not damaged.

In addition, a fall prevention jaw 13a is formed at the base end of the polygonal rod 13. When the lower plate 120 is pulled manually, the hollow park cylinder part 12 slides out of the polygon rod 13. Even if the hollow park barrel 12 slides on the polygon rod 13 and continues to reach the proximal end of the screw 13, the hollow park barrel 12 is caught by the fall prevention jaw 13a so that it does not fall out anymore. At this time, if the wheel W of the vehicle is further rotated, any component of the horizontal moving means will be damaged, but as described above, due to the torque limit clutch 14, the hollow park cylinder part 12 Idle in the fully disengaged position so that the component is not broken.

When the vehicle enters the lower plate 120 from the rear of the lower plate 120, if the vehicle is rear wheel drive, the rear wheels of the ground or lower plate 120 are positioned until the rear wheel is positioned between the pinch rolls 11 and 11 of the rear half. Since the vehicle continues to be driven at the rear end, it is possible to position the vehicle on the lower plate 120. However, when the vehicle is front wheel drive, the front wheel is idling between the pinch rolls 11 and 11 of the rear half, so that the vehicle cannot move forward any further. 120).

In order to prevent this, the recess cover 125 is formed by the hinge 126 across the lower plate 120 inwardly adjacent to each recess 123 in the lower plate 120. Therefore, when the vehicle, which is a front wheel drive, enters from the rear of the lower plate 120, when the recess cover 125 of the rear half is rotated to cover the recess 123 of the rear half, the front wheel of the vehicle is the recess cover of the rear half ( It passes through the 125 and is located between the pinch rolls 11 and 11 of the first half to drive the elevating unit driving means.

When the vehicle is parked on the fully elevated upper plate 110, and the vehicle is driven to the front wheel drive from the lower plate 120, the torque limit clutch 14 rotates slowly compared to the number of revolutions of the front wheels. The front wheel of the first pinch roll (11, 11) goes beyond the lower plate 120.

When the vehicle is rear-wheel drive and enters from the front of the lower plate 120 from the rear, the depression cover 125 of the first half may be rotated to cover the depression 123 of the first half.

Hereinafter, the operation sequence for parking two vehicles in two stages by the two-stage parking facility of the present invention will be described.

First, FIG. 1 is a state in which the upper plate 110 completely covers the lower plate 120, and a first vehicle enters from the rear or front inclined plate 117 and is seated on the upper plate 110.

Next, when the lower plate 120 is manually pulled, the hollow plate cylinder 12 slides on the polygon rod 13 while the lower plate 120 moves to the right.

Next, after the second vehicle enters from the rear or front inclined plate 127 and the front wheel or the rear wheel is seated between the pair of pinch rolls 11, when the wheel W of the first vehicle is rotated forward, the pinch roll ( 11) rotates clockwise. When the pinch roll 11 rotates in the clockwise direction, the hollow park barrel 12 rotates counterclockwise, and the rotational force of the hollow park barrel 12 passes through the vertical power transmission means, as shown in FIG. 10. By rotating the output shaft 34 counterclockwise, the screw nut 131 is moved to the right, thereby elevating the lifting unit 130.

When the screw nut 131 continues to move to the right and the lifting unit 130 fully rises, the hollow park cylinder 12 is idled by the torque limit clutch 14 in the hollow park cylinder 12, and thus the lifting unit ( 130) no longer works.

Next, when the lower plate 120 is manually pushed in the state shown in FIG. 10, the hollow plate cylinder 12 slides on the polygon rod 13, and the lower plate 120 moves to the left as shown in FIG. 11. Thus, two-stage parking of the first and second vehicles is completed.

In order to take out two vehicles parked in two stages in the two-stage parking facility of the present invention, the above-described parking operation procedure may be reversed.

First, when the lower plate 120 is manually pulled, the hollow plate cylinder 12 slides on the polygon rod 13 while the lower plate 120 moves to the right.

Next, when the wheel W of the second vehicle on the hollow park barrel 12 of the lower plate 120 reversely rotates, the hollow park barrel 11 rotates counterclockwise. When the pinch roll 11 rotates in the counterclockwise direction, the hollow park barrel 12 rotates clockwise, and the rotational force of the hollow park barrel 12 passes through the vertical power transmission means and rotates the output shaft 34 clockwise. By rotating the screw nut 131 is moved to the left to lower the lifting unit 130.

When the screw nut 131 continues to move to the left and the lifting unit 130 is completely lowered, the hollow park cylinder 12 is idle by the torque limit clutch 14 in the hollow park cylinder 12, and thus the lifting unit ( 130) no longer works.

Next, when the first vehicle is driven, the vehicle is discharged to the inclined plate 117.

Next, if the second vehicle continues to rotate in reverse, the second vehicle is separated from the hollow park barrel 12 and discharged. This completes the two-stage discharging of the first and second vehicles.

After parking, parking facilities are not used. As shown in FIGS. 1 to 4, a ring portion 61 is formed on the side of the lower frame 120 and the lifting unit 130, respectively, and as shown in FIG. 12, a wall located at the side of the parking space. A worm reducer-type winch 50 is installed in the structure 1, and a hook 52 is formed at the end of the rope 51 of the winch 50, so that the hook 52 of the rope 51 is connected to the lower frame ( 120 and the hook portion 61 of the elevating portion 130, respectively, and then turn the handle of the original 50 to manually turn the parking facility.

In this embodiment, the screw shaft and the screw nut have formed spirals in the counterclockwise direction, but they may also form spirals in the clockwise direction.

It will be appreciated that the present invention can be embodied in other specific forms without departing from the spirit constituting its main features. Accordingly, the above examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the above detailed description.

According to the two-stage parking facility of the present invention described above, since the screw and the screw nut are not required in the hollow park tube part, the assembling work is simplified and the manufacturing cost is reduced, and the upper and lower parts are formed in a plate shape so that the vehicle can be stably seated. In addition, parking is possible for all types of vehicles regardless of the length between the front and rear wheels. At the same time, the number of parts is reduced because there is no need for the gap adjustment device. To pull out a car parked at the top, you can pull out the car at the top without having to pull it out completely.
