Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gate opening/closing method and device, and in particular, to a parking lot gate opening/closing method and device in which a driver operates a transmitter in a predetermined manner from inside the car when entering or exiting a car in a parking lot. The present invention relates to a method and device for automatically opening and closing by remote control.

In conventional parking lots, a guide rail is laid on the ground between the opposing pillars of the gate.A steel fence door is guided on this guide rail, and the gate is opened and closed by manually moving the door. Another method is to stretch a chain or rope between the opposing posts of the gate, and then manually hook one end of the chain or rope to and from the posts, thereby preventing the gate from opening or closing. It is.

In such a gate, when entering a parking lot, the driver of the car gets out of the parking lot in front of the parking lot, opens the gate, gets back into the parking lot, enters the parking lot, leaves the car in the parking lot, and then exits. When exiting, it is necessary to close the gate. Even when driving out of a closed parking lot, the driver manually opens the gate when entering the parking lot alone, and even after driving out of the parking lot, the driver must get out of the parking lot and try again.
Work is required to close four gates. Opening and closing such gates in parking lots is a very troublesome task for drivers once they have gotten into their cars, especially when exposed to wind, rain, wind, snow, etc.
The disadvantage of this was that it was extremely painful for the driver at 16:00 due to bad weather such as storms. Additionally, the iron fence doors, chains, or ropes of the above gates are usually dirty with mud and dust.
If you open and close the door, especially on a rainy or snowy day, the dirt will stick to your hands and clothes, and you will get into the car with a dirty body, and you will also touch the steering wheel, which is usually clean, with dirty hands. The drawback was that holding the wheel was excruciatingly painful for the driver. In addition, in such parking lots, drivers often forget to close the gate at L7 when entering or exiting the car.
For this reason, there was a drawback that a person other than the contractor could use the parking lot without permission.

The present invention has been made to eliminate the drawbacks of the prior art described above.
'17' (The purpose of this is to automatically open the gate of the parking lot by remote control so that the driver can automatically open the gate of the parking lot each time the driver enters or exits the parking lot.) The purpose is to eliminate the mental pain and physical effort of having to get out of the car and open and close the gate.Another purpose is to automatically open the parking lot gate while the driver is still in the car. In this way, the use of the parking lot is made more efficient E2, and the entry and exit of cars is facilitated.

Another purpose is to automatically open the parking lot gate using a hand-held transmitter and close it automatically after a predetermined period of time has elapsed, thereby preventing drivers from forgetting to close the gate.
This is to prevent unauthorized use of the parking lot by anyone other than the contractor. In addition, other purposes are
A tension member of a predetermined length is provided on the opposite fixed part of the gate, and the tension member 1 is pulled in one direction to shorten the gate, the gate is closed, and the tension member is extended in the opposite direction to extend the tension member. To provide an inexpensive and effective method and device for opening and closing a gate in a parking lot, eliminating the need for installing a particularly strong iron fence door or the like in order to open the gate.

Another object of the present invention is to provide a transmitter that generates an electrical signal at a predetermined three times a night, and a compact gate opening/closing control device that operates in response to the electrical signal, so that the tension member can be operated reliably in an extremely short period of time. To provide a gate opening/closing method and device which does not require a driver to take much time to open/close the gate by shortening or extending the period of time, and which is trouble-free.

In short, in the method of the present invention, i1

FIGS. 4 and 5 show a second embodiment of the present invention, in which the same parts as in the first embodiment are given the same reference numerals, and only the different parts are shown in phase R. Only the different parts will be described below with reference numerals. 4 and 5, in this embodiment, the groove wheel 2 in the first embodiment is
Since the reel 50 is used instead of the groove wheel 5, the roller 27 related to the groove wheel, the pair of operating links 29, 29 that support the roller, the Lunoid SQL acting on the link,
@ is no longer necessary. The reel 50 has its central axis 50a
A ratchet 50C is integrally mounted on the outer surface of one of the pair of 7 flange 50b, which is rotatably mounted on a bearing between the pair of arms 26a of the support member 26 and arranged at a predetermined interval. The ratchet is adapted to cooperate with a ratchet pawl 40 which is acted upon by a lunoid SQL. Note that the center axis 5 of the reel 50
0a is connected to the rotating shaft (not shown) of the motor M, and one end is fixed to the center drum (not shown) of the reel 50 to one of the fixed parts 2.3 of the gate 1. Sat
The other end of the rope 6a having a predetermined length is fixed.

The present invention is constructed as described above, and its operation will be explained below. In FIG. 1, when a car is about to enter parking #4P or when a car 1o is about to go out, the opening/closing rope 6a of the gate 1 is in the closed state, so the driver Alternatively, the user temporarily stops the car in front of the 12-gate gate 1 and operates the digital remote control switch 15, which is a portable transmitter, in a predetermined manner.

For example, when the numbers 1.2 and 3 are pressed in sequence with the switch button, the transmitter 15 generates a predetermined electrical signal Sa'&-
Occur. The electrical signal is transmitted to the fixed part 3 on one side of the gate 1.
The sensors 7 and 8 installed in the sensor sense the voltage and generate a predetermined voltage.

In FIGS. 2 and 3, a receiver 21 receives lightning and pressure generated by a sensor 7 and transmits it to a control unit 23.

The control unit 23 uses a built-in microcomputer to determine whether the above-mentioned voltage signal matches a pre-stored gate opening code, and determines that t'Lfc and n match. The timer operates only if the switch Sρ remains open and the switch Sρ closes. Therefore 7lenoid SQL.

SQL is excited. At this time, the actuator 33 of the lensoid SQL is connected to the grooving wheel 25 via the connecting link 34.
The rope 6a in the V-shaped groove 25b is released from the nfC state. Runoid SQL at the same time.

The actuator 38 rotates the ratchet pawl 40 in the direction shown by arrow A via the connecting link 37 to disengage it from the ratchet 25 and release the groove wheel 25.

As a result, the tension rope 6a is stretched between one fixed part 2 of the gate 1 and the groove wheel 25, and due to its own weight, the groove wheel 25 is rotated in the counterclockwise direction in the figure as it is fed out and hangs down. When the rope 6a is almost completely relaxed between the fixing parts 2.3 of the gate 1 and comes into contact with the ground, the tension due to the rope 6a's own weight disappears, and the groove wheel 25 stops rotating. At this time, the gate 1 is in an open state, and the pouch 9 or lO can pass through the gate.

When a predetermined period of time has elapsed after the gate 1 was opened, as shown in FIG. 3, the control section 23 opens the switch St by checking the time elapsed using the built-in timer, as shown in FIG. Switch S is closed. Therefore, renrenoid SQL,
.
The C roller 27 is pressed against the rope 6a placed in the square groove 25b of the groove wheel 25. At the same time, the ratchet pawl 40
The restoring force of the spring rotates in the direction opposite to arrow A and engages the ratchet 25C of the wheel 25. At the same time, the motor M rotates and the rotation of its rotating shaft is transmitted to the central shaft 25a of the groove wheel 25. As a result, the groove wheel 25 is shown in Figure 2 as a circle.
This rotational movement is transmitted to the roller 27 via the rope 6a via L2, and the roller rotates in the counterclockwise direction. Due to the above rotational movement of the groove wheel 25 and the roller 27, the Giropro a is pulled to the right. When the rope 6a is rotated at a predetermined rotation speed of the motor M, the fixed portion 2 and the fixed portion 3 are brought into a shortened and tensioned state at a predetermined height. At this time, the predetermined rotation speed of the motor M is sensed by the nfC rotation speed sensor built into the control unit 23, and at the same time, the tension sensor 24 detects the predetermined rotation speed of the motor M.
senses the predetermined tension of the rope 6a, and the control section 23
The built-in nfC microcomputer receives signals from the rotational speed sensor and the tension sensor 24, performs arithmetic operations, opens the switch S1, stops the motor M, and the control section 23 becomes inactive. Therefore, the groove wheel 25 is also stopped (7 and its reverse rotation is prevented by the cooperative action of the ratchet pawl 40) and the ratchet 25C. At this time, gate 1 is in a closed-gf state, making it impossible to enter or exit the parking lot via Oki 9.10.

Note that the gate 1 does not necessarily need to be automatically closed by a timer built into the control section 23, and the control section 23 may not have a built-in timer. In this case, the driver leaves the car in the parking lot and closes the gate 1 by operating the transmitter 15 when getting out. Hayabusa of transmitter 15 at this time,
It goes without saying that the pulse signal is different from the signal when gate 1 is opened.

The first embodiment of the present invention operates as described above, and the second embodiment shown in FIGS. 4 and 5 differs only in its operation from the first embodiment.

I will clarify. As mentioned above, in this embodiment, the reel 50 is used instead of the groove wheel 25 in the first embodiment, so the roller 27, the solenoid SQL acting on the roller, etc. in the first embodiment are unnecessary. The fact that it is the fourth
As shown in the figure and FIG. Sensor 7.8, receiver 21.22, control unit 23, tension sensor 24, motor M1
The operation of solenoid SQL, etc. is the same as in the first embodiment.

In the illustrated state, the motor M rotates a predetermined number of times, the reel 50 winds the rope 6a 11z, b, the ratchet pawl 40 is engaged with the ratchet 50C [, , , to prevent the reel 50 from reversing 7, and the gate 1 This is a book that shows the closed state. In this state, for example λ, when the sensor 7 senses the electrical signal Sa from the transmitter 15, the control unit 23 closes the switch S while maintaining the switch S in the open state. Therefore, solenoid SQL is energized and its actuator 38 disengages ratchet pawl 40 from ratchet 50C and releases reel 50. As a result, rope 6a
The reel 50 is rotated counterclockwise in the H1 direction with its own weight corresponding to the length between the fixed part 2 of the gate L and the reel 50 in the fixed part 3, and then the reel 50 is relaxed and extended. The whole body touches the ground. At this time, the tension due to Ik of the rope 6a disappears, the rotation of the reel 50 is stopped, and the gate 1 is in an open state.

When a predetermined period of time has elapsed with the gate l in the open state, the control unit 23 switches the switch S to fully open.

will be closed. As a result, the solenoid SQL, li becomes inoperative, and the tip 40a of the ratchet pawl 40 is engaged with the former capital d-Ii (50 CK).

At the same time, the motor iV rotates, and the rotation of its rotating shaft is transmitted to the center shaft 50a of the reel 50, causing the reel 50 to rotate clockwise in the figure and wind up the rope 6a.

When the motor M rotates the same number of times 7 and the rope 6a is shortened and tensioned at a predetermined height between the fixed parts 2 and 3 of the gate 1, the control unit 23 ensures the predetermined rotation speed of the motor M. , the predetermined →→÷ tension of the stretched rope 6a is applied to the ship Pi's via the sensor 24, and the switch SI is opened to stop the motor M, and therefore the rotation of the reel 50 is also stopped and controlled at the same time. The part 23 is in an inoperative state, and the reversal is prevented by the cooperative action of the ratchet 50 and the ratchet 50C of the reel 50. At this time, Gate 1 is closed, and parking of cars and 14% of people are not possible.

t*IJ-ru 50 (d ratchet pawl 40 and ratchet 5
Due to the cooperative action with 0C, jψ eaves are stopped at 51.

In addition, in the present invention, the rope 6a, which is the rope 6 for opening and closing the gate, has a predetermined thickness and length and a predetermined amount. When released to open gate 1, the groove wheel or reel immediately rotates at high speed under the weight of rope 6a. It is for about 5 seconds.The horizontal level of the tension member 6 when the gate 1 is closed is such that it is difficult for an adult to pass through it, and it is difficult for an adult to step over his anus. .

Further, the time required to shorten the tension member 6 and close the gate 1 is approximately the same as the time required to open the gate, and is about 3 seconds to 5 degrees. In addition, the automatic closing of the tie gate 1 built into the control 1 part 23 is performed after the gate is opened for a time sufficient for the vehicle 9.10 to pass through it, e.g. 1 yen for at least 20 seconds
Since the tension member 6 is applied at the lapse of t1, the tension member 6 will not be shortened while the car passes through the gate 1 and act on the body of the car 9 or 10 from the bottom and damage it. In addition, the transmitter 15 that generates different signals for different time zones, such as daytime and nighttime subscribers in a parking lot, is separated by 2. By storing it in a computer, the present invention can be used in a wide variety of ways. Further, since the restraint release of the grooves 1 and 25 or the reel 50 is performed by a signal from the transmitter 15, the gate 1 is in the closed state 1. You can open gate 1 by rotating 25 stationary molds or 50 reels arbitrarily at the time of east! do not have. Therefore, it is impossible to relax and detonate the tension member 6 by unauthorized means and allow the car to enter the parking lot. Note that the groove wheel 25 allows the reel 50 to rotate in one direction and prevents the reel 50 from rotating in the other direction. rather than something that
A one-way clutch (i7J not shown) using a freewheel and its release groove (not shown) may also be used.

Since the present invention has the above-mentioned configuration, the gate of the parking lot is automatically opened by the driver of the car by remote control.
This provides the effect of eliminating the need for the mental pain and physical effort of having to get out of the car and open/close the gate each time the car is put in or taken out. The driver again]
It is now possible to automatically open the parking lot gate while you are inside the vehicle. In addition, the parking lot gate opens automatically by operating a hand-held transmitter, and the gate automatically closes after a predetermined period of time. It is possible to eliminate the arrangement of closing the gate due to 5n-, and also eliminate the arrangement of Nagisa of contractor Rita 1 using the parking @ -rf without permission. .By installing a long tension member with a constant n1 between the opposing fixed parts of the gate and pulling this i in one direction, it can be shortened (7
