Abstract

PURPOSE:To provide a fine design and improve reliability by firmly engaging a hook on the side of a body with a pin on the side of a case after a body has been pushed in to enable an operator to confirm locking. CONSTITUTION:When a key inserted into a lock 3 is turned in a normal direction, a main lever 4 makes contact with a first contact lever 15 to rotate an intermediate rotating means 10 in a normal direction, whereby a hook 5 is rotated from a closed point to an open point, allowing the hook to be disengaged from the pin 6. When a body 2 is drawn out, a fixed contact part 20 comes into contact with a part 8 to be contacted of a part to be engaged to rotate the means 10 in a reverse direction, whereby the hook 5 returns from the open point to the closed point. When the body 2 is pushed in, since the hook 5 is rotated when a second contact lever 17 contacts the part 8 of the part to be engaged, the closed point is maintained and then the hook contacts the pin 6 and is engaged after being displaced, following which the key inserted into the lock 3 is turned in a reverse direction, whereby the lever 4 returns to the closed point and the key is pulled out to finish locking.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism such as an automatic payment machine or an automatic teller machine used in a financial institution that locks and locks a main body that can be pushed into a case after the pushing is completed. Especially, at the end of pushing in, the hook on the main body side is automatically clicked on the pin on the case side, and the operator can confirm this and improve the reliability of locking and locking. The present invention relates to a locking / locking mechanism having a structure in which a member related to a stop is not exposed on the front surface of the main body.

[0002]

2. Description of the Related Art A conventional example will be described with reference to FIG. 6 which is a perspective view of a front surface portion thereof. This conventional example is a mechanism for locking and locking a main body that can be pushed into a case with respect to the case in an automatic payment machine or an automatic depositing machine used in a financial institution after the pushing is completed. In Figure 6,
A main body 30 which can be pushed into a case (not shown) is attached to a front plate 31 of the main body 30 such that an operation lever 32 provided with a lock 33 is exposed. A hook 34 for locking is directly connected to the inside of the operation lever 32. After pushing in the main body 30,
After inserting a key (not shown) into the lock 33 and rotating and unlocking it, the operating lever 32 is rotated clockwise to the position indicated by the broken line. By this rotation, the hook 34 is rotated clockwise to be hooked on a pin (not shown) on the case side, locked by the key, and then the key is pulled out from the lock 33. When pulling out the main body 30 for internal inspection, bill replenishment, collection, etc.,
On the contrary, after unlocking by the key, the operation lever 32 is rotated counterclockwise from the broken line position to the solid line position to remove the hook 34 from the pin (not shown), and this is performed.

[0003]

The conventional example has the following drawbacks. For one thing, after pushing in the main body 30, the operating lever 32 will rotate and be locked.However, since it cannot be confirmed whether the pushing in is completed or not, it is possible to smoothly lock it by rotating the operating lever 32. There is no guarantee that this will be done to. On the other hand, a member related to the latch such as the operation lever 32 is exposed to the front plate 31 of the main body 30, which is not only a hindrance in handling but also unfavorable in design.

The object of the present invention is to solve the above-mentioned problems of the prior art, and when the main body which can be pushed into the case is completely pushed in, the hook on the main body side automatically clicks against the pin on the side of the case. An object of the present invention is to provide a locking / locking mechanism having a structure in which an operator can confirm the locking and the reliability of locking / locking can be improved and a member related to the locking is not exposed on the front surface of the main body. ..

[0005]

A locking / locking mechanism according to a first aspect of the present invention is a mechanism for locking and locking a main body that can be pushed into a case with respect to the case after the push-in is completed. A lock and a locking part are provided on the case side, and a locked part is provided on the case side, and the lock is equipped with a main lever that is rotated by a key inserted to take open and closed positions. The stop portion has an intermediate rotating member that selectively takes an initial position or an end position; and by the rotation of the intermediate rotating member, the urging force of a connecting spring stretched between the intermediate rotating member and the intermediate rotating member is applied. A hook which is rotated via the hook to selectively take an open position or a closed position; the hooked portion corresponding to the hook, and a hook for hooking; And a contacted portion that is urged to return by releasing the contact. The first intermediate rotation tool is rotatably coupled to the main lever against a bias in only one direction from an initial posture on a first radius passing through a center of rotation of the intermediate rotation tool. Similarly, on the second radius thereof, the contact lever is rotatably coupled from the initial posture only in another direction against the bias and should contact the contacted portion of the hooked portion. A main lever that has an abutting lever 2 and a fixed abutting portion that is to abut the abutting portion of the hooked portion, and takes the open position by forward rotation of the key inserted into the lock. And the hook is disengaged from the pin by taking the open position through the intermediate rotating tool that takes the end position and the urging force of the connecting spring, and the hooked portion is pulled in the process of pulling out the main body. The hook returns to the closed position due to the contact between the contacted portion of the main body and the second contacting portion, and when the pushing in of the main body is completed, The hook is hooked to the pin after being contacted and displaced, and by reverse rotation of the key inserted into the lock, the main lever returns to the initial closed position, and then the key is pulled out. Locking ends.

The locking / locking mechanism according to a second aspect is the mechanism according to the first aspect, wherein the biasing force of the rotation of each of the first and second contact levers is stretched between the contact levers. It depends on the common spring.

[0007]

In the latching / locking mechanism according to claim 1, (1) the main lever is rotated from the closed position to the open position by the forward rotation of the key inserted into the lock before the main body is pulled out. It abuts the first abutment lever, which causes the intermediate pivot member to rotate from the initial position to the end position, which causes the hook to rotate from the closed position to the open position and disengage from the pin. (2) In the process of pulling out the main body, the fixed abutting portion abuts the abutted portion of the hooked portion, which causes the intermediate rotating tool to return from the end position to the initial position, which causes the hook to move from the open position to the closed position. Rotate to. (3) In the process of pushing in the main body, the hook keeps the closed position by rotating and escaping when the second contact lever comes into contact with the contacted portion of the hooked portion, Next, it is brought into contact with the pin, displaced, and then locked. Next, the main lever is returned from the open position to the closed position by the reverse rotation of the key inserted in the lock, but when the main contact lever contacts the first contact lever in the returning process, the first contact lever rotates. The return operation is not blocked by escaping after that. After the main lever returns to the closed position, the key is pulled out and the locking is completed.

In the locking / locking mechanism according to the second aspect, the first and second contact levers are rotationally biased by the common spring stretched between them.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a locking / locking mechanism according to the present invention will be described below with reference to the drawings. The configuration of the embodiment will be described with reference to FIGS. FIG. 1 is a side view of the embodiment when locked, and FIG. 2 is a plan view of the same.
In Fig. 1 and Fig. 2, this embodiment is roughly
At the end of pushing in the main body 2 against 1, the hook 5 on the main body 2 side is automatically hooked to the pin 6 on the side of the case 1, so lock it here and pull out the main body 2 from the case 1 conversely. Sometimes, unlocking will remove hook 5 from pin 6 at the same time and pull it out as it is. Now, inside the case 1, the pin 6 and the leaf spring 7 having the abutted portion 8 at the left end are provided.
And are fixed (see Figure 2). On the side of the main body 2, there is a front plate 2a to which a lock 3 is fixed on the front side, and there is an intermediate rotating tool 10 fixed to a base 9 mounted inside. Lock
The main lever 4 provided integrally with 3 is turned together when a key (not shown) is inserted into the lock 3 and turned. By the rotation of the main lever 4, the hook 5 is selectively opened or closed via an intermediate rotation tool 10 capable of selectively having an initial position and an end position.

In FIG. 2, the intermediate rotating tool 10 is mainly composed of
A rotating body 11 as a base, an abutment lever 15 (a first abutment lever of the invention) and an abutment lever 17 (a second abutment lever of the invention) rotatably coupled to the rotating body 11, Moving body 11
And a fixed abutting portion 20 provided integrally therewith. As will be described later in detail, the contact lever 15 contacts the tip end of the main lever 4, and the contact lever 17 and the fixed contact portion 20 form a leaf spring.
It contacts the contacted part 8 of 7. Also, the rotating body 11 is the base 9
It can rotate around the shaft 11a installed upright on the
By the biasing of a spring 14 which is stretched between the base 9 and the so-called dead center mechanism, the springs 14 and 13 come into contact with the stoppers 12 and 13, and two positionings are selectively performed (there is no intermediate positioning). .. The contact position with the stopper 12 (see FIG. 2) is the initial position, and the contact position with the stopper 13 after rotating clockwise from this position (see FIG. 4 described later) is the end position. The contact lever 15 is rotatable about a shaft 15a provided upright on the rotating body 11, and is urged by a spring 19 to contact and stop the stopper 16 in the clockwise direction. It can be rotated in the direction by contact with the tip of the main lever 4.
Similarly, the contact lever 17 has a shaft 17a that is erected on the rotating body 11.
In addition to being rotatable around, the spring 19 urges the stopper 19 in the counterclockwise direction to stop it by contacting with a stopper (not shown). Can be rotated by contact. Here, the spring 19 is the contact lever 1
It is stretched between 5 and 17 and has a shape to urge each of them in common, but it is of course possible to provide a separate spring for each of the contact levers 15 and 17.

Returning to FIG. 1, the hook 5 is rotatable about a shaft 5a erected on a base 9 and is stretched between the two so as to be connected to an intermediate rotating tool 10. The spring 23 abuts each of the stoppers 21 and 22 based on the dead center mechanism to selectively perform two positionings (no intermediate positioning). That is, when the hook 5 contacts the stopper 21
(See FIG. 1) is the closed position, and when it rotates counterclockwise from this position and comes into contact with the stopper 22 (see FIG. 3 described later), it is the open position.

The operation of the embodiment will be described mainly with reference to the flow chart showing the operation of the embodiment shown in FIG. 5 with supplementary reference to various side views and plan views of FIGS. In addition,
FIG. 3 is a side view of the embodiment when the latch is released (hook is opened), and FIG.
Is also a plan view thereof. In FIG. 5, step S
In 1, the key is inserted into the lock on the front side of the main unit and rotated in the unlocking direction to rotate the main lever from the closed (see Fig. 1) to the open (see Fig. 3) position. In FIG. 2, during the rotation of the main lever 4, the tip of the main lever 4 comes into contact with the tip of the abutment lever 15, and step S2
Behavior occurs. That is, in step S2, the intermediate rotating tool 10
Rotates from the initial position (see Figure 2) to the end position (see Figure 4). By the rotation of the intermediate rotating tool 10, step S
At 3, the hook 5, via the spring 23, rotates from the closed (see Figure 1) to the open (see Figure 3) position and disengages from the pin 6. In the next step S4, withdrawal of the main body is started.

In the process in which the main body starts and finishes pulling out, the fixed contact portion 20 that is pulled out and moves leftward together with the main body is the leaf spring 7 on the case 1 side, as presumed in FIG. It abuts on the protruding abutted portion 8 at the left end of the. By this abutment, the intermediate abutment tool together with the fixed abutment portion 20.
The 10 rotates counterclockwise around the axis 11a and returns to the initial position in FIG. However, at this time, unlike the state of FIG. 2, the contact lever 17 is located on the left side of the contacted portion 8. This is step S5. This rotation of the intermediate rotating tool 10 causes the hook 5 to return to the closed position via the spring 23 as shown in FIG. This is step S6. However, since the hook 5 at this time is located to the left of the pin 6, it is not hooked on the pin 6. Through the above process, the withdrawal of step S7 is completed. Here, step S8
Required operations such as banknote collection, replenishment and internal inspection are performed.

After the work, pushing in of the main body is started in step S9, and, as guessed in FIG.
The tip of 17 contacts the contacted part 8, but this contact lever
Since the shaft 17 can be rotated around the shaft 17a in the clockwise direction and can escape, the contact with the contacted portion 8 causes the intermediate rotating tool to move.
10 does not rotate. Therefore, the hook 5 moves to the right while maintaining the closed position. At the final stage of push-in, the lower inclined surface of the right end of the hook 5 comes into contact with the pin 6 and then rotates counterclockwise so as to ride on the pin 6 and then hooked to the pin 6 (see Fig. 1). At this time, the hook 5 "clicks" during the latching operation during the process of contacting with the pin 6 on the lower inclined surface of the right end of the hook 5, riding on the pin 6, and latching.
Give the operator the feeling of confirming that the hooking has been completed. This step is step S10. In the next step S11, the key is inserted into the lock and rotated in the locking direction to return the main lever from the open position to the closed position, after which the key is pulled out of the lock and the locking ends, and a series of main body The drawer / push-in operation is completed.
The main lever 4 comes into contact with the tip of the abutment lever 15 in the process of returning from the open position to the closed position (see Fig. 2), but this abutment causes the abutment lever 15 to move around the shaft 15a. Since it rotates clockwise and escapes, the return of the main lever 4 to the closed position is not hindered.

[0015]

In the locking / locking mechanism according to the first or second aspect of the present invention, in the process of pushing in the main body, the hook rotates when the second contact lever contacts the contacted portion of the hooked portion. It remains in the closed position by moving and escaping,
Next, the pin is brought into contact with the pin, displaced, and then locked, and then, the key is pulled out after the main lever returns to the closed position by the reverse rotation of the key inserted into the lock, and the locking is completed. Therefore, at the end of pushing the main body that can be pushed into the case, the hook on the main body automatically
It is locked with a click, and the operator can check it to improve the reliability of locking and locking, and since the member related to the locking is not exposed on the front of the main body, it can be an obstacle when handling it. Also, it is preferable because of its clean design.

Particularly, in the latching / locking mechanism according to the second aspect, since the first and second contact levers are rotationally biased by the common spring stretched between them, the number of parts is reduced. Saves space and reduces costs.
