Description

[Detailed Description of the Invention] (1) Purpose of the Invention The present invention electrically performs the function of preventing unauthorized unlocking of the disabling piece and the disabling element used in the conventional ticket blocker, thereby preventing unauthorized unlocking of the lower handle. This invention relates to a lock and a device that prevents both sides from being fully opened and both sides half-opened.

(2) Explanation of the prior art A ticket blocker is installed at each station at both ends of a block section, and through a meeting and joint operation of both stations, one ticket for that section is taken out from the ticket blocker at either station and then It is issued to trains as proof of operating permission to ensure safe block operation.

The tickets stored in the ticket blocker can be taken out by pulling out the lower puller provided on the box, but this lower puller must not be fully opened for the ticket blockers at both stations. , and situations in which it is not possible to adopt predetermined operating procedures because the handling is a joint effort between the own station and the partner station.
For example, a situation where the bottom handles of the ticket blockers at both stations are half-open (when the bottom handles are half-open, half of the ticket is visible but cannot be taken out. This situation indicates that the train from the other station has been acknowledged. It is necessary to prevent this. The release piece and release element have an important function of preventing unauthorized unlocking, as well as preventing failures such as unauthorized opening of both lower handles fully or partially. Next, the operation and operation procedure of the ticket blocker related to the operation of the control piece will be explained in the first part.
This will be explained using figures. As shown in FIG. 2, the release piece 1 is partially screwed onto the locking groove 3 of the fully open key 2 and once attached to the lower handle 4. In Figure 1, when a train departs from station A to station B,
First, station A conducts power transmission to obtain approval for train departure.
Handle P ₁ and send a localization transmission signal to B station. B
At the station, as part of the approval procedure, handle the unlocked power station _P2, pull out the lower handle 4 halfway, and then turn on the transmitting power station.
Handle P ₁ and send a half-open transmission signal to A station. A
At the station, receiving relay 5 operates upon receiving this signal.
The full opening key 2 is lifted by excitation of the horizontal wire ring 6. When the fully open key 2 is lifted up, the half open key 7 supported at its tip is lifted up in conjunction, and the lower handle 4 is unlocked and can be pulled out. When the lower puller 4 is pulled out from the normal position in the direction of full opening, the release piece 1 moves with the releaser 8 attached to the full open key 2 placed on it to keep the full open key 2 lifted, and the lower puller 4 To prevent a fully open key 2 from falling and being locked in a half-open position even if the transmission current is cut off while the lock is pulled out from the normal position to fully open. When the lower handle 4 approaches full opening, the release element 8 passes through the groove H of the release piece 1 and opens the groove 3 of the lower handle 4.
The fully open key 2 is dropped into the interior, and the fully open key 2 is forcibly restrained so that it cannot be lifted up, and the interlocking relationship between the fully open key 2 and the half open key 7 is severed, and when the half open key 7 falls, the lower handle 4 is locked in the fully open position. . As a result, once the lower handle 4 is fully opened, even if the transmission from station B continues and the horizontal line wheel 6 is energized, the fully open key 2
does not lift up, and the lower handle 4 cannot be moved from the fully open position. Here, only one ticket is taken out from the ticket blocker at station A, carried to station B, and delivered to the ticket blocker at station B through the upper handle 9. As a result, the lower handle 4 of station B can be placed in the normal position.

Next, when the transmitter P ₁ at station B is used to send a localization transmission signal to station A, the reception relay 5 at station A is activated, current flows through the vertical wire ring 10, and the half-open key 7 is lifted. , the lower handle 4 is unlocked. Now, if you push the lower puller 4 at station A fully open and towards the normal position,
The release element 8 escapes from the groove H and is supported on the release piece 1, thereby lifting the full opening key 2. This fully open key 2
Since the half-open key 7 is lifted by its edge by lifting, even if the transmitting current is cut off during the movement of the lower handle 7, the half-open key 7 will not fall and become locked in the half-open state. Once the lower puller 4 is in position,
Since the locking element 8 falls from the locking piece 1 and is locked with the fully open key 2, the transmission from station B continues and a current flows through the vertical train ring 10, causing the half open lock 7 to be lifted up. However, the lower handle 4 cannot be fully opened.
In the figure, reference numeral 11 denotes a polarity reversal device, which is provided on the lower handle 4 and is used to reverse or intermittent the polarity of the transmission current from the own station depending on the position of the lower handle 4.

(3) Problems with the Prior Art Next, with reference to FIGS. 1 and 2, the meaning of the shape of the dissolving piece and its problems will be explained using FIG. 3.

The plane of the first stage in Fig. 3 controls one of the functions necessary to prevent the lower handle 4 from being opened both half-opened, fully opened, or to take out a large number of slips, and is also important for ensuring full-opening operation control. It is a meaningful part.

If there is no surface and a surface is provided directly from the tip, when receiving a half-open transmission from the other station and fully opening the own station, the transmission between the other stations will stop at the moment the restrictor 8 rides on the surface. Tokiya,
When you release the unlocking electric key P ₂ at your own station, the full open key 2
When the half-open key 7 is lifted up and unlocked, the fully-open key 2 falls before the half-open key 7, so if the lower puller 4 is pulled during that short period, the locking element 8 will release the locking piece 1. The lower handle 4 is locked in a half-open position by the half-open key 7 which crawls into the underside of the door and falls later. As a result, both stations are half-open, causing problems.

In addition, when a surface is provided that extends to the surface, when the lower handle 4 is returned from fully open to the normal position, the polarity changer 11 comes into normal position contact before the release element 8 falls from the front edge of the surface. Since the ticket falls onto the tray 4a of the lower handle 4, it may cause a problem if both sides are fully opened or two or more tickets can be taken out.

Even if the first stage is provided with a surface,
When the release button 8 is on the CD surface, the lower handle 4
If the release element 8 is pulled too strongly, the second
If the ivy slides onto the surface of the step, both lower handles 4 will be fully opened, and the two terminals will open without joint operation by both stations.
This may cause obstacles such as being able to take out the above-mentioned slips, and the surface may become shorter due to wear etc.
Also when the operating gap between the release piece 1 and the release element 8 becomes large, a failure of both half-opening is likely to occur.

In short, since the shape and dimensions of the release piece 1 have a significant effect on the function of the ticket blocker, various studies have been conducted on its design, and the shapes shown in Figure 4 a to j are currently considered. However, it is difficult to generalize the superiority or inferiority of these shapes. If we place emphasis on preventing both sides from opening half-open, it will be difficult to fully open both sides, and it is difficult to fully open both sides. Incidentally, the shape of the dismantling piece of current pass blockers is mainly h or i.

Despite the various shapes of the release piece being devised in this way, the perfect shape has not yet been determined because of the transient effects caused by the mechanical interlocking of the fully open key and the half open key. This is because the mechanical interlocking function of the release piece and the release button cannot follow the phenomenon, the timing of transmission and unlocking operations, and the operating speed of pushing in or pulling out the lower handle.

(4) Explanation of the principle and operation of the invention Therefore, the present invention eliminates the interlocking relationship between the full-open key and the half-open key so that they operate separately, and also combines the mechanical interlocking mechanism of the release piece and the brake shoe with a switch and a relay. By replacing it with a combinational electrical control circuit, the operation of both keys can quickly follow the operating speed of the lower handle and the timing of transmission and unlocking operations, thereby preventing failures when the lower handle is fully opened or partially opened. .

(5) Structure of the Invention The present invention is designed to engage a half-opening lock 7 with a lower puller 4 that is pulled out of a box 12 of a slip blocker and takes out slips M stored in the box one by one. Half-open key engagement groove S ₁ , S ₂ , locked in position

(6) Description of embodiments of the present invention Examples of the present invention will be described below with reference to the drawings.
FIG. 5 shows a slip blocker to which the device of the present invention is applied. The box body 12 is provided with a voltage detector G, a transmitting voltage detector P ₁ , an unlocking voltage detector P ₂ , an upper handle 9 and a lower handle 4,
Deliver the voucher M into the box body 12 through the upper handle 9, accumulate the voucher M in the voucher gutter 13, and pull out the lower handle 4 fully under certain conditions through a meeting and joint work with the partner station to release the voucher. This is exactly the same as the conventional method in that the slips M dropped from the gutter 13 onto the tray 4a are taken out one by one.
FIG. 6 is an example of a control circuit. On the lower handle 4 are half-open key engagement grooves S ₁ , S ₂ , and S ₃ into which the half-open key 7 is dropped and locked in the normal, half-open, and fully open positions, respectively.
and a full-open key engagement groove R for engaging the full-open key 2 between normal position and half-open position. The half-open key 7 and the full-open key 2 are each pivotably supported so as to be movable up and down,
Half-open solenoid SM for vertical drive on half-open key 7
Further, the full-open solenoid RM for vertically driving the full-open key 2 is connected to the full-open key 2. MS ₂ is a lock detection switch, MS ₃ is a drawer detection switch, and MS ₄ is a push detection switch. When the drawer detection switch MS ₃ pulls out the lower puller 4 from the normal position to the fully open direction, the lower puller 4
It is a switch that operates by detecting the stereotaxic position of the
Further, the push-in detection switch _MS4 is a switch that operates by detecting the fully open position of the lower handle 4 when the lower handle 4 is pushed in the normal position direction from the fully open position. The lock detection switch MS ₂ has the lower handle 4 in the normal position - fully open or fully open.
This is a switch that operates by detecting changes in movement while moving between localizations. Both switches are controlled by the shapes of cams _C2 to _C4 attached in the longitudinal direction of the lower handle 4. A specific example of arrangement is shown in FIG. NRSR is a constant reverse position holding relay that operates with the output signal from each switch MS ₂ to MS ₄ . This constant reverse position holding relay NRSR controls the half-open solenoid SM and the fully open solenoid RM, and the wiring diagram of its control circuit is shown in FIG. That is, the lifting contact nrsr of the constant reverse position holding relay NRSR is interposed in the power circuit of each solenoid SM and RM, and the power supply circuit wiring of the constant reverse position holding relay NRSR is equipped with a pullout detection switch MS ₃ and a receiving relay LRR, which will be described later. A first connection including a launch contact 1rr in series, a push detection switch _MS4 , a second connection including a launch contact 1nr of a receiving relay LNR (described later) in series, a lock detection switch _MS2 , and a launch contact of the relay NRSR. The parallel wiring with the third wiring including the nrsr in series is connected in series. In addition, the control circuit includes a reception relay LNR that operates upon receiving the localization transmission from the other station, a reception relay LRR that operates upon receiving the half-open or full-open transmission from the other station, and a reception relay LRR that operates upon receiving the localization transmission from the _other station. An unlocking relay _P2PR issues an unlocking command according to the polarity of the transmitting current of the other station and the status of the own station, and a polarity reversal detection switch detects the normal position, half open, and fully open position of the lower handle 4. A polarity reversing relay that switches the polarity of the transmitted signal by the operation of MS ₁ and the switch MS ₁ .
PCR, a document delivery memory relay TDSR that selectively drives the half-open solenoid SM to unlock the half-open key 7 at the time of document delivery, and the rotational displacement and restoring operation of the document tab 14 provided on the document gutter 13. a delivery detection switch TD that detects and operates the document storage relay TDSR, each relay output and a half-open key 7;
It is equipped with a transmitter circuit consisting of an AND circuit for the output of the fall detection switch SL, a disconnector TSC, a signal oscillator SOC, a telephone TEL, etc. By the way, the reception relay LNR is a localization reception relay that operates by receiving localization transmission from the other station.
LRR is a counter-receiving relay that operates by transmitting full-open or half-open transmissions from the other station.

In the embodiments described above, conventional mechanical components are replaced with electric circuits as much as possible, but with the exception of each detection switch MS ₂ to MS ₄ , constant reverse position holding relay NRSR, half-open solenoid SM, and fully open solenoid RM. A conventional control circuit may be used as is.

Next, the operation of the present invention will be explained. The operating instructions and procedures are exactly the same as the current pass blocker.

When a half-open transmission is received from the other station, the contact lrr of the reverse reception relay LRR is configured, so the
In the figure, the constant reverse holding relay NRSR is energized through the draw-out detection switch MS ₃ , and the half-open solenoid SM and the fully open solenoid are energized through its contact nrsr.
RM is energized, and the half-open key 7 and the full-open key 2 are lifted by the operation of both solenoids SM and RM. When the lower puller 4 is pulled out from the normal position to fully open, the lock detection switch MS ₂ operates just before the half-open key engagement groove S ₁ in the normal position passes directly below the half-open key 7.
Through the switch MS ₂ , from localization to full opening,
The constant reverse position holding relay NRSR is self-held, and then the withdrawal detection switch _MS3 is opened. Therefore, even if the electric current transmitted from the other station is cut off during this time, the half-open key 7 or the fully open key 2 will not fall and become locked in the half-open position. When the lower puller 4 is pulled out further, the lock detection switch MS ₂ is opened at the position just before the slip can be taken out, the constant reverse position holding relay NRSR falls, and the half-open key 7 is moved to the fully open engagement groove.
The lower puller 4 is locked in the fully open position by being engaged with _S3 . Once the lower puller 4 is fully opened, the pullout detection switch _MS3 remains open even if it continues to receive half-open transmission signals from the other station, so the constant reverse position holding relay is activated.
The NRSR does not operate and the lower puller 4 cannot be moved from the fully open position. Only one ticket is taken out from the lower handle 4, delivered to the train, and transported to the destination station. The partner station receives the ticket and delivers it to the ticket blocker, which allows the lower handle of the partner station to be placed in the correct position.

Next, when the localization transmission is received from the partner station, the connection lnr of the localization reception relay LNR is configured, the constant reverse position holding relay NRSR is energized through the push detection switch MS ₄ , and the half open solenoid SM and the fully open solenoid RM are energized.
operates, and the half-open key 7 and the full-open key 2 are lifted. When the lower puller 4 is fully opened and begins to be pushed in the normal position direction, the half-open key 7 moves to the fully open half-open key engagement groove _S3.
Immediately before passing directly under the lock detection switch MS ₂ operates, and through the switch MS ₂ , the constant reversal holding relay NRSR is self-held from fully open to normal position, and then the push detection switch MS ₄ is opened. .
Therefore, even if the transmission current from the other station is cut off during this time, the half-open key 7 or the fully open key 2
The lower handle 4 will not be locked half-open due to falling. When the lower puller 7 is pushed further, the lock detection switch MS ₂ is released before the slip falls from the slip gutter 13 onto the tray 4a, and the constant reversal holding relay is activated.
The NRSR falls and the lower handle 4 is locked in place with the half-open key 7. Once the lower puller 4 is locked in its normal position, the push-in detection switch MS ₃ is open even if the transmission continues from the other station, so the constant reverse position holding relay NRSR does not operate, and therefore the lower puller 4 cannot be returned to full throttle.

FIG. 9 shows the relationship between the engagement groove provided in the lower handle and the operating timing of each detection switch 4. In the embodiment, the lock detection switch MS ₂ and the push detection switch MS ₄ use lift-up contacts, and the pull-out detection switch MS ₃ uses a drop contact.

(7) Effects of the Invention As described above, the present invention uses an electrical control circuit consisting of a combination of a switch and a relay in place of the conventional mechanical interlocking mechanism consisting of a combination of a brake piece and a brake element, and furthermore, Since the half-open key and the full-open key operate separately, there is no delay or timing shift due to mechanical interlocking, and there is no difference in timing of transmission from the other station, unlocking operation, or changes in the operating direction or position of the bottom handle. It is possible to drop and pick up half-open and fully-open keys in an immediate response, completely preventing unauthorized unlocking of the lower handle of the pass block between the own station and the other station, as well as failure to open both fully open and both half-open. .

Therefore, according to the present invention, the reliability and security of the slip blocker can be significantly improved.
