[0001] This invention relates to a parking device, particularly to a parking device which
includes an upright power-driven wheel made in two sections having casings suspended
between said sections for the housing of many automobiles.
[0002] As is well known, the increase the parking space is an important problem to be solved
in a crowded city. It is desired that maximum utilization of limited space car can
be achieved regarding the parking of motor vehicles.
[0003] It is therefore a main object of this invention to provide a rotatable parking device
thereby reducing the amount of parking space required on the ground.
[0004] Accordingly, a rotatable parking device of this invention includes an upright power-driven
wheel with two parallel sections which is rotatably supported in a vertical plane,
and a plurality of casings for the purpose of housing motor vehicles pivotally connected
between the sections. Each casing has a bottom, two opposite open sides adapted to
be an ingress and an egress for a motor vehicle, and means for immobilizing said motor
vehicle, said motor vehicle associated with the casing when the wheel rotates. In
this way, many motor vehicles can be housed in the casings. These motor vehicles can
also be maintained in a horizontal position while rotated about the wheel within a
vertical plane. The wheel may be located either above or partially under the ground
so as to conserve parking space.
[0005] Other features and advantages of this invention will become apparent in the following
detailed description of the preferred embodiments of this invention with reference
to the accompanying drawings, in which:

Fig. 6 is a schematic view showing a rotatable parking device located partially underground.
Fig. 7 is a perspective schematic view showing another type of casing for a rotatable
parking device according to this invention.
[0006] Referring to Fig. 1, a perspective view of a rotatable parking device of this invention
is shown. The rotatable parking device includes an upright wheel 20 rotatably supported
by legs 10. The lower ends 11 of the legs 10 are respectively fixed on the ground.
The wheel 20 is driven by a driving device 40 associated with the legs 10. The driving
device 40 includes a motor 41, a transmission case 42 and a power supply means (not
shown). A control device 50 is mounted near one of the end 11 of the leg 10 for controlling
the driving device 40. In this respect, the wheel may be driven to rotate at a predetermined
angle and a given speed. The wheel 20 has two parallel rims 21, 21 and a plurality
of spokes 22 connected to an axle 23 (see Fig. 3) which is driven by the driving device
40. The wheel spokes 22 are preferably engaged with the wheel axle 23 by nuts and
bolts , as best illustrated in Fig. 4, so that they can be separated from the wheel
axle 23 for transport. A plurality of casings 30 for housing motor vehicles 100 are
pivotally connected between the rims 21, 21. Thereby, the casings 30 are maintained
in a horizontal position while the wheel rotates in a vertical plane.
[0007] Referring to Fig. 2, a perspective view of a casing 30 for housing a motor vehicle
100 is shown. Each of said casings 30 has a pivot hole 31 at its top portion which
is passed through a pivot pin 32 so as to be pivotally connected to the rims 21, 21
of the wheel 20. Each casing 30 has a bottom 33 and two opposite, opened sides adapted
to be an ingress and an egress for a motor vehicle 100. Rows of ribs 34 are provided
on the bottom 33 of the casing 30 so as to prevent the vehicle 100 which is left in
the casing 30 from slippage when the wheel 20 rotates. Wedge blocks 70 are preferably
provided under the wheels 101 of the motor vehicle 100 for blocking the motor vehicle
100, as best illustrated in Fig. 3. The two opposite opened sides of the casing 30
may arranged in a direction perpendicular to that of the axle 23 or parallel to that
of the axle 23, as shown in Fig. 7. Two hatches 35, 35 are respectively and pivotally
connected to the edges of the opened sides of the casing 30 so that said hatches 35,
35 can be opened or closed thereby permitting the vehicle 100 to be loaded or unloaded
by passing over one of said hatches 35 when one of the casings 30 is rotated to its
lowest position, as shown in Fig. 3. The hatches 35, 35 are preferably controlled
by an oil pressure system.
[0008] Referring to Fig. 5, a side view of another preferred embodiment of a rotatable parking
device is shown. The embodiment includes two power-driven upright wheels 20′, 20′.
Each of the wheels 20′, 20′ is provided with a plurality of casings in a manner similar
to that described hereinbefore so as to increase the number of motor vehicles to be
housed.
[0009] It is to be understood that the rotatable parking device can also be mounted in a
cavity 80 formed in the ground with the upper portion of said parking device partially
located above the ground, as best illustrated in Fig. 6. In this situation, the ends
of the wheel axle 23 are rotatably mounted on the opposing walls which are defined
by the cavity 80 under the ground. A shield 90 is preferably provided over the cavity
80 so as to protect the rotatable parking device from rain, heat, and dust etc. A
vehicle 100 can enter or leave the casing when the wheel 20 rotates to a predetermined
position in a direction perpendicular to that of the axle 23 of the wheel 20, (as
shown in Fig. 6), or in a direction parallel to that of the axle 23 of the wheel 20
with another type of casing 30′ having different opened sides thereof with respect
to the casing 30 in Fig. 6, as best illustrated in Fig. 7.
