SELF-ENFORCING PARKING SYSTEM
Abstract
A self-enforcing parking system is disclosed herein wherein the
motorist must deposit the proper monetary amount in a meter before
he can remove his vehicle from the parking stall. The stall
comprises a flat plate having wheel guides thereon which aid in
properly positioning the front wheels of the vehicle as it is
driven into the stall. A front curb is positioned at the forward
end of the stall to position the vehicle front wheels on a pair of
pressure pads having normally open switches therein. A pair of
barrier plates, driven by a hydraulic cylinder means, pivotally
move upwardly behind the vehicle front wheels after the vehicle is
properly positioned on the pressure pads. When the motorist desires
to leave the parking stall, he must deposit the proper amount of
coins in the meter to cause the barrier plates to be lowered by the
hydraulic cylinder means. The parking charges are directly
indicated on the meter to indicate the fee which must be paid.

Description
Conventional parking systems are generally unsatisfactory due to
the fact that persons can park in parking spaces utilizing parking
meters without depositing money into the meters. The biggest
disadvantage in available parking is in the private parking area
such as a parking lot having a large number of parking spaces.
These areas generally do not come under police jurisdiction since
they are for private management. Thus, if parking meters are
provided in the parking lot, the drivers sometimes attempt to avoid
depositing money in the parking meters since they realize that a
ticket for a parking violation will not be issued. The solution to
the above problem has been to provide attendants at the parking
areas to collect the money for the parking changes. Obviously, such
a solution is less than desirable due to the costs and
adminstrative details associated therewith.
One means of eliminating the problems enumerated above are
disclosed in applicant's earlier U.S. Pat. No. 3,503,480 which
issued Mar. 31, 1970. The instant invention represents a
significant advance in the earlier device since the entire unit is
positioned above the ground to facilitate ease of installation and
maintenance. Additionally, the instant invention represents a
significant improvement over the earlier device due to the improved
parking meter and due to the improved barrier plates and electrical
circuitry of the instant invention.
Therefore, it is a principal object of this invention to provide a
method and means of self-enforcing parking.
A further object of this invention is to provide a means for
parking a vehicle utilizing a parking meter wherein the driver pays
for the time the vehicle was in the parking space.
A further object of this invention is to provide a self-enforcing
type of enforcing system.
A further object of this invention is to provide a parking system
that prevents the vehicle from being removed from the parking space
until a predetermined amount of money has been inserted into a
parking meter.
A further object of this invention is to provide a parking system
which eliminates the need for the driver to insert money into the
parking meter in advance.
A further object of this invention is to provide a parking control
device which indicates when the vehicle is properly parked in the
parking stall.
A further object of this invention is to provide a self-enforcing
parking device which eliminates the need of a person being in
attendance in a parking lot.
A further object of this invention is to provide a self-enforcing
parking system having a barrier plate means provided thereon which
compensates for various vehicle sizes.
A further object of this invention is to provide a self-enforcing
parking system having a meter which directly indicates the monetary
charges on rotating wheels.
A further object of this invention is to provide a self-enforcing
parking system including a stepping motor and gears which drives a
rotating charge wheel to indicate the parking charge.
A further object of this invention is to provide a self-enforcing
parking system including limit switches which prevent the charge
wheels from rotating past their maximum charge.
A further object of this invention is to provide a self-enforcing
parking system including means for lowering a parking barrier when
the indicator charge wheels are zero set through the deposit of
coins into the parking meter.
A further object of this invention is to provide a self-enforcing
parking system wherein conventional 115 Volt AC power is
transformed into 24 Volt DC power to prevent serious shocks to the
motorist.
A further object of this invention is to provide a self-enforcing
parking system including a parking stall having guide means thereon
to insure that the vehicle will be properly parked thereon.
A further object of this invention is to provide a self-enforcing
parking system which is mounted above ground level to facilitate
ease of maintenance and installation.
A still further object of this invention is to provide a
self-enforcing parking system which is economical of manufacture,
durable in use and refined in appearance.
These and other objects will be apparent to those skilled in the
art.
This invention consists in the construction, arrangements and
combination of the various parts of the device, whereby the objects
contemplated are attained as hereinafter more fully set forth,
specifically pointed out in the claims, and illustrated in the
accompanying drawings, in which:
FIG. 1 is a perspective view of the parking stall:
FIG. 2 is a top view of the parking stall:
FIG. 3 is a top view of the parking stall having the wheel guides
and cowl removed therefrom to illustrate the internal components of
the system:
FIG. 4 is a perspective view of one of the barrier plates:
FIG. 5 is a schematic view of the electrical circuitry of the
invention:
FIG. 6 is a partial exploded persective view of the meter housing;
and
FIG. 7 is an exploded perspective view of the internal components
of the parking meter.
The numeral 10 designates a parking stall which is adapated to be
placed on any suitable supporting surface usch as concrete,
asphalt, etc. The entire stall 10 is above ground to permit ease of
installation and maintenance. A parking meter 12 would normally be
located adjacent the stall 10 so as to be convenient for the
motorist.
Stall 10 comprises a flat base 14 having a flanged cowling 16
(preferably steel) mounted thereon. Curb 18 is provided at one end
of the stall 10 to limit the forward travel of the vehicle entering
the stall. A pair of flanged guides 20 and 22 are secured to base
14 at the sides thereof as illustrated in FIG. 1. FIG. 3
illustrates the base 14 with the cowling 16 and guides 20, 22
removed therefrom. Hydraulic cylinder 24 is secured to base 14 and
has its bases 26, 28 in fluid communication with a hydraulic power
unit 30 so that the cylinder rod 32 can be selectively moved
inwardly and outwardly with respect to the cylinder 24. The outer
end of rod 32 is secured to a linkage 34 which is connected to a
barrier activating shaft 36. The shaft 36 is rotatably supported in
bearings 38, 40, 42 and 44. Barrier plates 44 and 46 are mounted on
the shaft 36 for movement therewith. Plate 44 is substantially flat
and has outer end portion 48, intermediate portion 50 and inner end
portion 52. Plate 46 is substantially flat and has outer end
portion 54, intermediate portion 56 and inner end portion 58.
Extension of rod 32 causes the shaft 36 to be rotated so that the
plates 44 and 46 will be raised with the outer end portions,
intermediate portions and inner end portions thereof providing a
means for compensating for various car sizes (width, tire size,
etc.). As seen in FIG. 1, the shaft 36 extends outwardly through a
suitable opening formed in cowling 16 with the plates 44 and 46
being positioned between the cowling 16 and guides 20 and 22
respectively. A pair of pressure pads 60 and 62 are positioned on
base 14 in the relationship shown in FIG. 1 and include normally
open pressure switches 64 and 66 therein respectively which are
closed upon the vehicle wheels driving thereon.
In FIG. 1, the numerals 68, 70, 72, 74, 76, 78, 80 and 82 refer to
the following elements: main timer, 24 hour-7 day timer, heater,
elapsed timer No. 1, elapsed timer No. 2, electrical terminal
means, on-off switch, and 24 Volt DC transformer, respectively.

The normal method of operation is as follows. The vehicle enters
the parking stall 10 with the front wheels thereof passing over the
lowered barrier plates 44 and 46. The vehicle is driven into the
parking stall until the front wheels thereof rest on the pressure
plates or pads 60 and 62 and position against the front curb 18.
When the vehicle's front wheels are on the pressure pads 60 and 62,
the switches 64 and 66 are closed and send an electrical impulse to
energize the main timer motor 186. Both of the switches 64 and 66
must be closed before such an electrical impulse will be sent to
the main timer motor. The closing of the switches 64 and 66 also
causes the red indicator light 184 to be lighted thereby indicating
to the driver that the vehicle is properly parked in the parking
stall. The closing of the switches 64 and 66 also causes an
electrical circuit to be completed through the electrical hydraulic
power unit 30 to cause the extension of the cylinder rod 32 for a
predetermined distance thereby moving the barrier plate linkage 34
and shaft 36 to raise the barrier plates 44 and 46. The raising of
the barrier plates 44 and 46 trap the vehicle's front wheels
between the barrier plates and the front curb. The configuration of
the barrier plates 44 and 46 is such that they will compensate for
various vehicle widths and tire sizes.
An electrical circuit is also made to the 7 day week, 24 hour day
timer 70. Timer 70 is energized at all times through its own off-on
switch and circuit. When the other electrical circuit is made by
the switches 64 and 66 being closed, the pre-set cam switches in
the timer 70 energizes either the elapsed time timer 74 or elapsed
time timer 76. When either timer 74 or timer 76 is energized, an
electrical circuit is completed from timer 74 or timer 76 through
the transformer 82 to the stepping motor 154 to indicate an initial
charge on the charge wheels 160 and 162. The electrical impulse
furnished to the stepping motor 154 causes it to be energized and
advances the stepping motor gear 156 for a predetermined distance.
The stepping motor gear 156 causes the gear 152 to be also rotated
which causes the cents charge wheel 162 to be rotated for a
predetermined distance to indicate the amount of the initial
parking charge. The elapsed time timers 74 and 76 would ordinarily
be pre-set to permit different charges for different days of the
week or different hours of the day. The timers 74 and 76 has
pre-set predetermined time elapses to enable them to energize the
stepping motor for different predetermined lengths of time.
As long as the vehicle remains parked in the parking stall, the
energized elapsed time timer would oeprate and at each pre-set,
predetermined amount of time elasped, the timer would energize the
stepping motor 154 (through the transformer 82) to advance
additional charges on the charge wheels 160 and 162. The stepping
motor gear 156 engages the cents charge wheel gear 152 as elapsed
time charges are being determined by the elapsed time timer. When
the cents charge wheel 162 has been advanced by the stepping motor
until the charge reaches one dollar, the cents wheel then engages
the dollar charge wheel 160 to advance it to indicate a one dollar
charge with the cents charge wheel 162 then indicating a 0 cents
charge. In the event that the elapsed time timer would continue to
advance charges on the charge wheel until a predetermined maximum
amount of charges had been reached, levers on the cents and dollar
charge wheels would engage the switches 148 and 142 respectively to
discontinue the power to the elapsed time timer which would prevent
the unit from 0 setting itself.
When the motorist returns for his vehicle, he would read the total
amount of charges indicated on the indicator charge wheels 160 and
162. The motorist would then insert coins into the coin slot block
110 to pay for his parking time. The coin handling mechanism
operates in the same manner as standard Duncan Model 50, 60 or
Model 70 parking meter. The coin is inserted into the coin slot
block 110 and falls into the coin carrier assembly 84. The motorist
then turns the operating handle 116 so that the coin is carried
around the coin carrier until the edge of the coin strikes the coin
segment 102. The coin segment 102 causes the coin switch lever to
be extended to make from one to five of the switches 166, 168, 170,
172 or 174. The number of switches made would be determined by the
types of coins used such as nickels, dimes, quarters. When the coin
switches are made, they send an electrical impulse to the stepping
motor 154 to energize the same so that it is operated in the
reverse direction. The stepping motor gear 156 then turns the cents
indicator charge wheel 162 back a predetermined distance. The
amount of reverse rotation applied to the wheel 162 would depend
upon the number of coins that had been inserted. After enough coins
have been inserted to return the indicator charge wheels back to
their 0 settings, the hydraulic system is energized by the closing
of two switches by the levers on the charge wheels. The energized
hydraulic power unit then causes the cylinder rod 32 to be
withdrawn into the cylinder to cause the cylinder rod to return to
its home position. The withdrawal of the cylinder rod 32 causes the
barrier plates 44 and 46 to be returned to their horizontal
position. The main timer circuit continues to operate for a
predetermined time so that if the vehicle is not removed from the
parking stall and the pressure switches 64 and 66 are still closed,
it would then re-start the operation. If the vehicle is removed
from the pressure plates, the main timer runs for a predetermined
time and then shuts down the entire unit until the next vehicle is
parked.
Thus it can be seen that an extremely novel self-enforcing parking
device has been provided. The device indicates monetary charges on
a rotating wheel to indicate to the motorist the exact parking
charges. The rotation of the charge wheels are accomplished through
a stepping motor and gear arrangement and the reversal of the
stepping motor indicates the amount of fee paid. The fact that the
115 Volt power sources transformed to 24 Volts direct current power
insures that the motorist will not suffer harmful shock if a
malfunction should occur in the system. The entire system is
mounted on a metal plate and is encased above ground level to
insure ease of maintenance and installation. The guiding system on
the device insures that the vehicle will be properly moved into
position on the parking stall. Thus it can be seen that the
invention accomplishes at least all of its stated objectives.
