Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lock structure for an opening / closing door, which includes a housing and an openable / closable door provided in the housing, such as a financial automation device, and which is opened and closed by using a key. It is a thing.

[0002]

[Prior art]

 A conventional door lock structure will be described with reference to FIGS. 3 and 4, taking a financial automation device as an example. FIG. 3 is a rear perspective view of the financial automation device. In FIG. 3, reference numeral 1 denotes a housing of the financial automation device such as an automatic cash depositing / dispensing machine installed in a bank or the like, and the inside of the housing 1 on the rear side. It has a rear door 2 that can be opened and closed to perform maintenance and inspection. The rear door 2 rotates in a clockwise direction with one of the left and right sides of the housing 1, that is, the left side in the figure as a fulcrum, to open the rear side of the housing 1 and rotate in a counterclockwise direction. The structure is such that it closes. Further, a banknote deposit / withdrawal machine, a card reader, a control unit, a power supply unit, etc. are housed inside the housing 1.

Reference numeral 3 denotes a handle arranged at the free end side of the rear door 2, that is, near the right side in the figure, and 4 denotes a lock arranged near the handle 3, which allows the rear door 2 to be opened. A lock structure for permitting or prohibiting is configured. Although not shown, this lock structure also has a card pass function that allows the rear door 2 to be opened by using a card.

FIG. 4 is a side view of a conventional lock structure. In FIG. 4, reference numeral 5 denotes a post formed so as to rotate integrally with the rotation operation of the lock 4, and one end of the slide stopper 6 is shown. Is engaged with the protrusion 6a. The slide stopper 6 is a plate-like member having a protrusion 6a at one end that engages with the post 5 and a bent portion 6b extending in the horizontal direction at the lower end. The slide stopper 6 extends vertically from the bent portion 6b. The main body that has risen has a structure in which a horizontally elongated notched slide groove 6c is provided. Within the range of the slide groove 6c in the longitudinal direction, the slide stopper 6 slides in the direction of the arrow in the figure. To do.

Reference numeral 7 is a link having a post 7a engaged in the slide groove 6c at the lower end, and the other end of the link 7 is an iron core of a solenoid 8 as a sliding means separate from a spring described later. And a rotation fulcrum 7b is provided between the iron core and the post 7a. When the iron core of the solenoid 8 moves back and forth, it rotates about the rotation fulcrum 7b. Then, the slide stopper 6 is slid in the arrow direction in the figure through the slide groove 6c.

A bracket 9 fixes the solenoid 8 and is attached to the rear door 2. Reference numeral 9a denotes a post projecting from the bracket 9 toward the slide stopper 6, and engages with the slide groove 6c to support the movement of the slide stopper 6. Reference numerals 10a and 10b denote a pair of upper and lower lock shafts attached to the handle 3, and as shown in the figure, the lock shaft 10 is provided with respect to a pair of protrusions 3a protruding in two directions from around the handle 3. The lock shaft 10a is attached so as to extend in the vertical direction, and the lock shaft 10a extended upward has a structure in which the upper end thereof can be engaged with the engagement hole 1a formed in the casing 1, The lower end of the lock shaft 10b extending downward has a structure capable of engaging with the engaging hole 1b formed in the housing 1, and the upper end 10c thereof is different from the lock shaft 10a. The contact portion 10c extends above the protrusion 3a and contacts the bent portion 6b of the slide stopper 6 to hold the locked and unlocked states of the lock structure. That.

Reference numeral 11 denotes a micro switch which is provided in the engagement hole 1 a of the housing 1 and detects the tip of the lock shaft 10 a. When the presence of the lock shaft 10 a is detected, the energization of the solenoid 8 is cut off. To do. Numeral 12 is a spring as an urging means attached to the other end of the slide stopper 6, and this spring 12 urges the slide stopper 6 so as to always move in the direction of the lock shaft 10b. .

The operation of the lock structure having the above configuration will be described. First, when unlocking the lock structure in the locked state, a key (not shown) is inserted into the lock 4 and rotated clockwise. , The post 5 that interlocks with the lock 4 moves to the position 5 '. With the movement of the post 5, the slide stopper 6 in which the post 5 and the projection 6a at one end are engaged is resisted to the biasing force of the spring 12 to the position shown by the chain double-dashed line in the figure. And slide it. As a result, the other end of the bent portion 6b of the slide stopper 6 moves from the position A to the position B in the figure.

Further, when the card pass function is used by using a card (not shown), the solenoid 8 is energized, whereby the iron core portion of the solenoid 8 retracts, and the position changes from C to D in the figure. Then, the upper end of the link 7 connected to the iron core portion is pulled to a position D in the figure, so that the link 7 rotates clockwise about the rotation fulcrum 7b. As a result, the post 7a of the link 7 moves in the slide groove 6c and moves to one end of the slide groove 6c in the figure.

When the card pass function is not used here, the solenoid 7 is not energized, so the post 7a of the link 7 does not move from the position shown by the solid line in the figure. That is, even if the slide stopper 6 moves, the post 7a is engaged in the slide groove 6c, so that the movement of the slide stopper 6 is prevented via the slide groove 6c even if the link 7 does not rotate. There is no such thing. That is, the sliding movement of the slide stopper 6 is locked by either one of the rotation operation by the lock 4 using the key, the energization operation of the solenoid 8 by the card pass function, or the access from both. The shafts 10a and 10b can be moved up and down.

In this way, when the other end of the bent portion 6b of the slide stopper 6 slides to the position shown in B in the figure, there is nothing that obstructs the upward movement of the lock shaft 10b, so that the handle 3 is operated. Is possible. Therefore, when the handle 3 and the clockwise rotation shown by the arrow in the drawing rotate, the lock shaft 10a lowers the lock shaft 10a via the protrusion 3a, and the lock shaft 10b also moves through the protrusion 3a at two points in the drawing. Raise to the position indicated by the chain line. As a result, the upper end of each lock shaft 10a and the lower end of the lock shaft 10b come out of the engaging holes 1a and 1b of the housing 1, respectively, so that the locking structure between the housing 1 and the rear door 2 is unlocked. It will be.

Even if the key is inserted into the lock 4 in this state and the lock 4 is rotated to return to the original position, the other end of the bent portion 6b of the slide stopper 6 is located at the upper end of the lock shaft 10b. The slide stopper 6 cannot return to its original position because it abuts against the abutment portion 10c, and therefore the lock 4 cannot return to its original position. On the other hand, when locking the lock structure, the lock shaft 10a is raised through the protrusion 3a by rotating the handle 3 in the counterclockwise direction after the handle 3 is rotatable, and the lock shaft 10b is rotated. Moves down and their ends enter the engaging holes 1a 1 and 1b of the housing 1, respectively. As a result, the rear door 2 is locked with respect to the housing 1.

At this time, when the micro switch 11 provided in the engagement hole 1a detects the upper end of the lock shaft 10a, the solenoid 8 is de-energized, and the iron core portion of the solenoid 8 is closed. In the figure, it is free between C and D. Then, when the lock 4 is rotated back to the original position by the key, the post 5 is also interlocked to return from the position of the post 5'shown by the chain double-dashed line to the position shown by the solid line, and the slide stopper 6 is moved to the second position. Release the state where it is held at the position indicated by the dotted line. As a result, the spring 12 attached to the other end of the slide stopper 6 returns to the original position by the urging force of the spring 12, and returns to the position A shown by the solid line in the figure, so that the housing 1 and the rear door 2 are securely locked. Will be in a state.

Note that some users may use the lock 4 only in an emergency and usually open and close the rear door 2 only by using the card pass mechanism, so that the lock 4 does not rotate. Therefore, even if the post 5 is in the fixed position, the slide stopper 6 must be slidable from the position A shown by the solid line in the figure to the direction B.

[0015]

[Problems to be solved by the device]

 However, the above-mentioned conventional technique has the following problems. That is, in order to make the locked state reliable, the slide stopper 6 is returned to its original position with the pair of lock shafts 10a and 10b entering the engaging holes 1a and 1b of the housing 1. In order to prevent the lock shafts 10a and 10b from slipping out of the engaging holes 1a and 1b, it is necessary to surely return the slide stopper 6 to the original position from the position where the slide stopper 6 slides by the lock 4 or the card path function. It That is, unless the slide stopper 6 returns to the original position, the locked state of the rear door 2 cannot be surely established.

However, the force for returning the slide stopper 6 to the original position does not have the post 5 that interlocks with the lock 4, and is a spring that is an urging means attached to the other end of the slide stopper 6. Relying on 12 recovery capabilities. The post 5 has a function of slidingly holding the slide stopper 6 at a predetermined position when releasing the lock structure, and does not have a function of returning to the original position. Therefore, the slide stopper 6 has no other choice than to rely on the reliability of the urging means, and there are variations due to long-term use and individual quality relationships, and it is not necessarily a reliable slide mechanism. I could not say.

In order to ensure the reliability of the slide mechanism as described above, various improvements can be made, but this leads to high cost and a large mechanism, which is technically satisfactory. It wasn't something. The present invention has been made to solve the above-mentioned problems, and when the slide stopper is slid, the reliability is not affected by variations in component quality or fatigue due to long-term use. It is an object of the present invention to provide a door lock structure that can reliably slide and make the lock structure between the housing and the door reliable.

[0018]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention ensures that the lock state between the housing and the door can be surely held by rotating the lock by using the key to slide the slide stopper without fail. That is, when locking the door that is openable and closable on one side of the housing to the housing, a lock that is rotated by a rotating operation using a key and an arc-shaped rotation operation that is interlocked with the rotation of the lock. The post is provided with one end, and one end of the post is engaged with the post so that the post can be slid by the pivotal movement of the post, and can be moved in the left-right direction through a separate slide means regardless of the pivotal movement of the post. The slide stopper and the slide stopper are rotatable when they are in a slidable state, and are supported so that they can move up and down with the other end of the slide stopper when they are in the original position without sliding. The lock shaft is engaged with one end of the lock shaft and is prevented from moving up and down to be unrotatable, and by rotating the lock with a key, the posts are moved to move the posts. By sliding the id stopper and rotating the handle in this state, the lock shaft that interlocks with the handle can be moved within a specified range, and when the lock shaft is moved in the specified direction, the housing and door are locked. When the lock shaft is returned to the original position, the lock between the housing and the door is released, and the slide stopper is returned from the slide position to the original position in the locked state. In the lock structure of the door that holds the locked state by preventing the return of the lock to its original position, a substantially L-shaped engagement groove is provided at one end of the slide stopper, and the rotation movement of the lock is performed in the engagement groove. Engage a post that rotates in conjunction with the slide stopper and slides the slide stopper in the left-right direction in conjunction with the rotation of the lock via the post. Those were Unishi.

[0019]

[Action]

 With the above-described configuration, when the lock is rotationally operated by using the key, the post moves together with the lock. At this time, since the post is engaged with the engaging groove formed in the slide stopper, the post moves in the engaging groove along the shape of the engaging groove. A force for sliding the slide stopper in the left-right direction is applied, so that the slide stopper slides in conjunction with the rotation of the lock.

Since the handle becomes rotatable in this state, the lock shaft interlocking with the handle is moved in a predetermined direction by rotating the handle to lock the housing and the door. Further, the lock between the housing and the door can be released by rotating the handle in the reverse direction and returning the lock shaft to the original position. Then, in the above-mentioned locked state, if the lock is returned to the original position using the key, the post moves in the engaging groove of the slide stopper in the same manner as in the lock releasing operation, and the post moves against the slide stopper. A force for sliding movement is applied, and this action surely returns the slide stopper to the original position. As a result, the other end of the slide stopper comes into contact with one end of the lock shaft, prevents the lock shaft from returning to its original position, and maintains the locked state between the housing and the door.

[0021]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing the lock structure of the door of this embodiment, and FIG. 2 is an enlarged view of the main part of the lock structure for explaining the returning operation of the slide stopper. In FIGS. 1 and 2, only the structure of the slide stopper, which will be described later, is different, and the other parts are almost the same as in the conventional example. Therefore, the same reference numerals as in the conventional example are used here. , The description is omitted.

Reference numeral 13 denotes a slide stopper according to the present embodiment. This slide stopper 13 has a substantially L-shaped engagement groove 13 a for engaging the post 5 of the lock 4 on the slide stopper 6 shown in the conventional example. The other structure is the same as that described in the conventional example. That is, it has a bent portion 13b extending in the horizontal direction along the lower end side, and the main body portion rising from the bent portion 13b in the vertical direction has a slotted slide groove 13c cut in the horizontal direction. With the structure provided, the slide stopper 13 slides in the direction of the arrow in the drawing within the range of the slide groove 13c in the longitudinal direction.

In the above-mentioned configuration, when sliding the slide stopper 13 to the position shown by the chain double-dashed line in the figure, first insert a key not shown in the lock 4 and rotate it in the time direction indicated by the arrow in the figure. Then, the post 5 interlocks with this operation and rotates clockwise. At this time, since the post 5 is engaged with the engagement groove 13a of the slide stopper 13, the post 5 presses the inner surface of the slide groove 13c while moving in the engagement groove 13a to apply pressure to the slide stopper 13a. 13 is moved to the left in the figure.

As a result, the other end of the slide stopper 13 slides from the position A to the position B in the figure, and the lock can be released. Here, the operation for returning the slide stopper 13 that has slid and moved to the original position from the moved position will be described. In the unlocked state, the post 5 and the position 5'shown by the chain double-dashed line in the figure, and the slide stopper 13 also exists at the position 13 'shown by the chain double-dashed line in the figure. At this time, in order to lock the rear door 2, the handle 3 is rotated counterclockwise to move the lock shaft 10a upward and the lock shaft 10b downward so that the tip ends of the lock shaft 10a of the housing 1 are moved. After engaging with the engaging holes 1a and 1b, the lock 4 is returned to its original position by a key.

Since the post 5 is interlocked by the rotation operation of the lock 4, the post 5 is moved from the position 5 ′ to the position 5-1 in the engagement groove 13a of the slide stopper 13, and eventually the predetermined original 5 is moved. Although it will be returned to the position, the amount of movement of the slide stopper 13 when releasing the lock by this movement is returned here. Therefore, the other end of the slide stopper 13 returns from the position B in the figure to the position A.

As a result, the slide stopper 13 is surely returned to the original position without depending on the restoring force of the spring 12, and the key can be pulled out from the lock 4.

[0027]

[Effect of device]

 As described above, according to the present invention, a substantially L-shaped engaging groove is provided at one end of the slide stopper, and the engaging groove is rotated by interlocking with the rotating operation of the lock that is rotated using a key. The post is engaged with the slide stopper, and the slide stopper is slidably moved in the left-right direction through the post in conjunction with the rotation operation of the lock.

Therefore, when the lock is rotated, the slide stopper always slides in either the left or right direction. Therefore, the handle is rotated to move the lock shaft, and a part of the lock shaft is engaged with the housing. With the structure in which the housing and the door are locked, the slide stopper can also be returned to the original position by returning the lock to the original position, and when the slide stopper returns to the original position, Even if the lock shaft is returned from its engaged state to the original state, it will not come into contact with the slide stopper and cannot return. As a result, the lock between the housing and the door is securely held.

That is, in the present invention, the return operation of the slide stopper, which conventionally relies on the restoring force of the biasing means attached to the slide stopper, is interlocked with the rotation operation of the lock in the present invention to reliably perform the slide operation of the slide stopper. As a result, the sliding motion of the slide stopper can be reliably supported without causing deterioration in quality due to deterioration of quality due to variations in quality of the biasing means and fatigue due to long-term use as in the past. Therefore, it is possible to secure the improvement of security by obtaining a reliable door lock structure.

Further, since this lock structure is a simple structure in which the engaging groove is simply formed in the slide stopper, there is an effect that the cost is not increased.
