Description

Description Key confinement prevention device Technical field

This invention locks the door of a car (hereinafter abbreviated as "car") while leaving the ignition key (hereinafter abbreviated as " ¹ -key") inside the car. (Hereinafter referred to as “key confinement”). Drivers of vehicles equipped with this equipment will be almost free from the foolishness of key confinement. Therefore, you have to worry about the possibility of trapping the key. You will be able to wipe the door and lock the car door with confidence. For this reason, it is expected that the opportunity to lock the car door will increase, and this will greatly contribute to the improvement of social events such as car theft. Background art

Conventionally, there are two types of devices that are considered to have been invented for the purpose of preventing key confinement.

The first is a device that locks and unlocks the door with simple remote control. When locking or unlocking doors via this type of device, the keys do not directly touch the doors, and the doors closed outside the car are operated by a simple switch operation. The procedure is completed. This suggests that there is a tendency to prevent key confinement here, but it is not perfect. This is because the possibility of locking the door locking remote device cannot be excluded. Here, the confinement of a remote device is left as an unsolved problem, as silly as the confinement of a key. The conventional technology is supplemented with a "key forgetting warning device". That is, inside. It is premised on the possibility of key confinement by keyless locking (described later) that is mediated by pushing in the key. Considering the existence of inside locking 'knobs to be used during indoor stays, it is considered that these multi-faceted mouth-locking machines Wi are very complicated. Couldn't these be centralized around the inside locking 'knob? This perspective will play an important role in the following. The second is a device that sounds an alarm simply by trying to open the door with the key left on the key switch. This type of device prevents the user from forgetting to remove the key from the key switch, and is collectively referred to as "forgetting the key removal warning!" As described above. This is a splendid thing that does not reflect on the first. However, there are too many opportunities to report, and even if the key is left on the switch and it is safe to leave the car, an alarm will be issued. That is, this alert must be limited only when it is needed. So what exactly is the necessary opportunity? That is when the key is left on the key 'switch; Oi is locked. If there is an alarm at that time, it will be an alarm to prevent key confinement. It seems that the warning is limited to this. Therefore, the purpose of the present invention is to provide this key confinement prevention device.

However, in this case, there is a concern that the location of the key removed from the key switch may become careless, and it is not possible to exclude the possibility that the key will be locked while the key is left in the car. In. In other words, there is still some anxiety about locking the door. Therefore, in the new invention, there is provided a key-trapping prevention device that completely eliminates these fears and does nothing other than performing a clearly secure door lock without any fear. The purpose is to do so. That is, an object of the present invention is to provide a device that makes it impossible to confine a key. Disclosure of the invention

The problem to be solved by the present invention is to improve the process of inside locking 'knob setting (pushing) when locking the door, which can cause key confinement. If the key is locked, the key is not involved in locking the door at all. In other words, lock the door by closing the door while pulling the handle of the door after performing the procedure of inside locking 'knob depressing while leaving the key on the key switch. I will do it. This is key confinement. This method of locking the door without any involvement of the key is a common practice with care to avoid trapping the key. This locking method is specifically referred to herein as “keyless locking” because the key is not controlled at all.

In order to avoid trapping the keys at this point, it is sufficient to properly handle the procedure of inside locking-pushing the knob. To do this, consider the task of establishing the following process by controlling the inside locking 'knob.

When the key is left on the key switch and the door is open, the beeper sounds only when you press the inside locking knob. When opening the door with the mouth key left in the key switch, the inside locking 'knob must be fixed and cannot be pushed in.

It is necessary to remove the key from the key switch to change the state of the items (a) and (b) to another state (cancelled state) in order to end the state of (a) .

(Ii) It shall be confirmed that the operation of item (c) has been effective for the two-item item.

The inside locking 'knob is automatically set via the section C following the section C, and the procedure proceeds to keyless locking. Therefore, the following points are established as means for solving these problems.

The switch linked to the key inside the switch, the switch linked to the opening of the door, the switch linked to the pushing of the locking knob, and the buzzer connected to the DC power supply. Prepare circuits arranged in series. This is called a triple series circuit. (Corresponding to claim 1)

Inside-locking for fixing the inside-locking knob. Install a holding circuit that is controlled by the knob. This circuit has two series circuits and a unit circuit.

-An electrical obstacle that prevents the switch from moving to the key inside the switch and the switch moving from opening to opening the door by securing the locking, locking, and knob. They are arranged in series with the power supply along with the objects. (Corresponding to Claim 2.) In the unit circuit, a switch interlocking with the opening of the door and an electrical obstacle for fixing are arranged in series with the power supply. (Corresponding to claim I, paragraph 3 in the claims, including the paragraph nu)

Attach a transmitter that is about the size of a key holder to the keypad, and install a receiver as a receiver that receives calls from it near the lock on the door beside the driver's seat. A receiver / relay circuit is provided to handle this process via a release switch (described later).

Install a confirmation device to confirm the operation of the “side locking” knob control.

。 Install an automatic inside 'locking' knob push-in (set) circuit so that the e-term can be realized at the time of reception in the null term. (Corresponds to claim 4) This circuit includes a switch that turns on when the door is opened, a switch that turns on when receiving, And inside locking. Set devices for setting knobs are arranged in series.

At the time when the door is closed, the function of these key confinement prevention devices is not exhibited because the door-linked switch is switched off. In other words, inside locking. The knob exists as a door locking button for the resident of the room, which is independent of the inside, locking, and knob. (Control release state) However, when the closed door is opened, the switch for door movement is switched on, inside locking, and the knob are under control. In this state, in the case of the serial connection circuit of the three-way and two-way switches, the function is activated under the condition that the key is in the key switch. And, in the case of a unit circuit, it functions regardless of whether the key is in the key switch or not. The function of the triple series circuit is to generate an alarm when the inside locking 'knob is pressed. The function of the double series circuit and the unit circuit is inside, locking, and the knob is fixed. That is, keyless locking in a state where the key is in the key switch is prohibited. The latter two circuits here are also called holding circuits. To release the state of each of these three circuits, the key can be taken out of the key switch. In other words, at that time, the inside-locking knob can be pushed in freely without an alarm in the case of a triple series circuit and without fixing in the case of a double series circuit. In the case of a unit circuit, when the transmission of the transmitter attached to the key comes within the reception range of the receiver, the inside locking 'knob can be freely pushed in by hand without fixing. become. In connection with this reception, an automatic inside is provided separately from the manual. ■ Locking. A knob push-in circuit is also provided. In this case, the inside lock, which is fixed with the door open, automatically locks the inside lock-knob when the removed key is within the reception range. Unlocking after keyless locking is by key. Izu In such a case, key confinement is prevented by taking out the key. In the unit circuit as the holding circuit, a condenser / beep circuit is provided together with the receiver's relay circuit. In the latter, the switch is linked to the opening of the door, and the load is stored in the condenser, so that the beer is put on standby and can be used for the ode.

The door is opened at a larger angle in preparation for the null term to release the knob that is connected and fixed to the unit circuit, and another door-linked switch at that large angle Is switched on, and the function of the receiver's relay circuit is exhibited. The function of this circuit is that the transmission from the transmitter attached to the key is received by the receiving antenna of this circuit installed near the exit of the door. If the above-mentioned push-in was impossible, the inside locking was performed. ■ To release the function of the holding circuit via the release switch to enable the push-in of the knob. In order for this reception to be achieved, the receiver attached to the key must be within the reception range of the receiving antenna. This means that the key is removed from the key switch. In addition, as another cooperation at the time of this reception, the beep of the beep circuit is uttered. This is inside locking, which lets you recognize that the control state of the knob has changed, but at the same time, it helps to recognize that the key has been removed from the key switch. are doing.

The driver can then push the inside locking, knob, and knob out of the car and pull the door handle to close the door with confidence. This is what is called a keyless lock that prevents the key from being trapped. When the door is closed, the switch linked to the door is switched off, so that all functions of the key confinement prevention device stop and the power consumption for the device becomes zero. The door is unlocked with a key. Also, the process of pushing the inside ■ mouth-locking / knob can be performed automatically instead of manually. This is a function of the automatic inside locking ■ knob press-in circuit. A manual switching switch is provided in this circuit. If you want to release the keyless lock halfway after the knob is depressed automatically, you can switch to manual with this manual switch. Locking ■ Pull up the knob.

BEST MODE FOR CARRYING OUT THE INVENTION

[Embodiment 1] In the triple-series circuit type corresponding to the first aspect of the present invention, a switch which is turned on in response to a key in a key switch, and a switch which is operated in response to opening of a door. • Switch that turns on, inside, locking, and switch in conjunction with the knob set. • Switch that turns on and an alarm sounder, such as a buzzer or a timbre, are connected in series with the power supply. Prepare an array of circuits.

[Embodiment 2] As a double-series circuit type corresponding to the description in claim 2, the switch which turns on the switch in conjunction with the key in the key switch, and the interlock with the opening of the door A switch and an inside that turns on when the switch is turned on. Provide a circuit in which electrical obstacles for locking the knob are arranged in series with the power supply. Here, the insides ■ Electrical obstacles for locking and fixing the knob are, for example, inside and mouth locking. When the knob is pushed in, the movement of the knob is transmitted to the locking machine. A control device for stabilizing the operation of the mouth, the mouthpiece and the knob with the stabilization of the mouth movement. That is, inside ■ The locking 'knob, and thus the locking of the rod, is limited only when the key is left in the key switch and the door is opened. This is one of the holding circuits.

[Embodiment 3] In the third embodiment, a unit circuit type corresponding to the third and fourth aspects and an apparatus supplemented with an automatic inside locking 'knob press-in circuit and the like will be described. The technical items that make them up are mainly as follows. These include "holding circuits", capacitor beep circuits, "receiver relay circuits", "automatic side-locking, knob push-in circuits" and "door interlocking circuits". It is a crossing bridge 'rotary' gate 'switch'.

The “holding circuit” is located inside the door and Its function is to control the linkage from the king / knob to the locking mechanism, that is, to control (fix) the intervening pads. Here, the following items are connected to form a serial arrangement. A power drive electromagnet, a door interlocking switch, a release switch, a ^ source, and a thyristor for the hook for rod control. The gate of this series ■ As a switch, a crossing bridge with a door speed of m is used. Here, the switch for release or the switch for standby is normally in the state of switch-on or switch-off, respectively. The switch automatically returns to the normal state as soon as the state is completed.

This holding circuit is established when the door-linked switch is turned on at the moment when the closed door is opened. This is followed by the closing of the door, the bridging, the mouthful, and the gate-switch as the gate, the switch being turned on, and the holding circuit functioning. become. In other words, an electromagnet appears due to the current flowing in the circuit, and attracts one end of the iron piece penetrated through the rotating shaft fixed at both ends in the middle. At this time, the other end is used as a load control hook. ■ Locking-The movement of the rod that cooperates between the knob and the locking mechanism is obstructed. Act on. If this is not possible, inside locking, pushing in the knob is impossible. Therefore, keyless locking cannot be performed at this time. This state is maintained until the release switch is set to the switch-off state by the cooperation of the receiver's relay circuit or the door is closed. The gate is switched off immediately after the switch is turned on. This is the function of the rotary gate switch. The reason for using this is that even if the release switch is linked to the inside lock and the knob is released and then automatically returned to the switch-on state, the inside lock is used. . Knob fixing The purpose of this is to make it impossible unless the door is closed once. The “condenser beep circuit” is installed inside the door and has a function to emit a beep to encourage the receiver to recognize that the reception and the cooperative action have been performed by the receiver relay circuit. This circuit consists of two parts. They are the capacitor one circuit part and the beep circuit part. In the former, door-linked switches, capacitors, power supplies, and door-linked crossing bridges / rotary gates ■ switches are arranged in series. In the latter, a beep speaker and a standby switch are connected to this capacitor.

At the moment when the closed door is interrogated, the door speed switch is switched on and is established. This is followed by the rotary of the Doer-gate 'switch' is turned on, accumulates electric charge in the capacitor, and is immediately switched off, and the receiver relay circuit is provided in the beep circuit. Switch as a coordination action associated with receiving from ■ ■ Wait for on. This link turns on the standby switch, which releases the load on the condenser. This flow produces a short beep. In this case, the rotary gate switch is used not for the gate but for charging the capacitor.

“Automatic Inside Locking / Knob Push-In Circuit” is an automatic inside power. Power for locking / knob pushing. Electromagnetic stone for drive, standby switch, door interlock switch, power supply and so on. The manual switching switches are arranged in series. This circuit is opened only when the door is opened and the door is opened at a larger angle after the door that is linked to the holding circuit or the condenser beep circuit is switched on. The switch is turned on and the function is activated by another respective door-linked switch together with the circuit. When the standby switch is turned on as a cooperative action from the receiver and relay circuit, the power drive electromagnet works to lock the rod inside. · The knob is moved to the side where the knob is pressed. Note that manual switching は switch ON of the switch means disconnection of this circuit, and the function of this circuit stops.

The “receiver relay circuit” consists of a part of the receiver and a relay section. The relay section is switched on at a larger angle. The door interlock switch, the switch for releasing the holding circuit, the switch for standby of the beep circuit, and the automatic inside lock. Three relay solenoids, a DC power supply, and a thyristor are connected in series to communicate the respective connections to the standby switch and the like of the knob press-in circuit. A part of the receiver is connected as the gate of this thyristor. Here, the rectification function and the smoothing function are provided, starting with the antenna. The antenna is effectively shielded, and its directivity is limited so that the reception distance is limited and only after the key has been removed from the key switch and moved to the door exit. It is assumed that the call is received. With this reception, the gate of the above-mentioned thyristor is switched on, and the relay section operates the three relaying solenoids in cooperation with the respective circuits. An appropriate time difference is required for these three types of cooperation.

The door-linked crossing 'bridge' mouthful 'gate' switch is a crossing consisting of two plunges crossing the axis of rotation at right angles, as shown in Figure 1. A rotor that rotates with a bridge on it, a switch button pillar that extends in contact with it and extends in a direction parallel to its axis of rotation, and both ends of each bridge of a rotating crossing bridge. It is composed of a surrounding terminal ring fixed to the vehicle body so that it contacts the inner surface. A spring is fixed to the switch button column so that it is wrapped inside.When the button is pressed with a finger, a repulsive force occurs and the switch button returns to its original position when the finger is released. Perform reciprocating motion. A metal lever is fixed to the bottom of this pillar. You. The rotor meshing with this lever surrounds its axis of rotation with two serrated teeth facing each other. One tooth profile of the saw consists of a line parallel to the reciprocating motion of the lever attached to the column, and an oblique line that forms an acute angle with the line. The teeth are fixed to face each other in a positional relationship deviated by half the rotational direction component distance of one tooth from the position turned back so as to be symmetrical about the straight line connecting the teeth of the teeth one after another. When the column lever reciprocates between these two tooth rows, the lever pushes the diagonal lines of the teeth and rotates the rotor by the distance corresponding to the rotational direction component. First, when the switch button is pressed, the oblique line on the outward path of the lever is pressed and rotated, and the rotor is rotated until the lever comes close to a line parallel to the reciprocating motion. At this point, the outbound route is over and the rebound of the pillar spring is obtained, and the vehicle returns to the return route. Figure 1 shows the state at this moment. Also on the return path, push the oblique line of the other row of teeth facing the lever, and move by the distance of the rotation direction component as in the outward path. In this way, when the switch is pressed once and the lever is reciprocated one time, the mouth rotates only half of the teeth facing each other, that is, the angle corresponding to the movement of the distance of one tooth in total .

Also, each bridge fixed at its midpoint so as to form a T-shape perpendicular to it on the rotation axis of the rotor forms a part of an independent electric circuit, and both ends take them. It is in contact with the inside surface of the ring, the ringing terminal and ring fixed to the vehicle body. Terminals of the electric circuit are fixed in pairs on the smooth surface inside the ring so as to be symmetrical about the center point of rotation. Crossing 'Bridge' Rotary Gate switch-With the buttons left untouched, both ends of each bridge rest on the inner surface of the ring without any terminal I have. When the switch button is pressed once, each pair of terminals facing each other across the respective bridges is rotated for a very short time by rotating the crossing bridge at the corresponding angle. Each bridge is taken to complete the electric circuit. Crossing Bridge Pressing the button on the 'rotary' gate 'switch is equivalent to switching it on and then immediately switching it off. At this point, the two types of electrical circuits picked up by these terminal pairs are alternately routed on the surrounding terminal ring every 90 degrees and the thyristor of the holding circuit is used for each. Gate switch and condenser linked to the door ■ The door interlocking port for charging inside the beep circuit is connected repeatedly as a tally gate switch. Therefore, repeatedly pressing the rotary gate switch causes each of the gates connected to these to function repeatedly in order to cause these actions to occur.

Industrial applicability

Keyless locking can be given as a method of locking doors, which is usually considered to be used by most drivers, but in performing this, the "controlled It can be pointed out that pushing in the mouth-knob is not possible without the procedure to remove the key from the key switch. From this, it can be said that a double or triple series circuit type key confinement prevention device alone is a sufficiently effective invention. This is because, unlike the warning device for forgetting to remove the key, the three-unit series circuit type key lock prevention device does not sound an alarm even if the door is opened with the key left on the key switch. It doesn't sound unless you press the inside-mouth-knob. Also, in a double-series circuit type device, the inside locking knob itself cannot be pushed in to fix the inside locking knob. The features of the unit circuit type prevention device are the inside locking, the key for pushing in the knob, the key ■ The key is removed from the switch, and the transmitter mounted as a holder is attached to the end of the door. The antenna close to the receiving antenna ί% is to guide the insert, knob, and knob into a pushable state. By doing this, secure keyless locking is possible. In other words, this is the so-called “secure keyless locking that makes key confinement impossible”. This has the effect that the driver can safely and easily lock the door when leaving the vehicle. Further, at the time of the above-mentioned cooperative operation after reception, a beep is made to urge the user to take out the key or to recognize the key passing through the door, thereby confirming the presence of the key. is there. Also, in order to automate the procedure of inside locking 'knob press-in by installing an automatic inside lock-knob press-in circuit, the key is removed from the key switch and taken out of the door. When passing, a beer is uttered and confirmed. At that time, the inside locking knob is automatically depressed, at which point the snake is in the process of keyless locking. After that, closing the door while pulling the handle of the door from outside the car completes this keyless locking. This is an easy-to-use, secure keyless lock that has the psychological effect of simpler, safer, and more secure that the locking procedure has been reduced. This automatic inside locking 'knob press-in circuit is equipped with a manual switching switch that can be switched to' manual 'to manually press the inside-locking knob. . In other words, it is an ordinary secure keyless lock. The unlocking of the locked door is by key, and the extra ones are omitted.
