Abstract

PURPOSE:To prevent the failure in returning a release lever of a financial automatic machine, by releasing the engagement between a bent part and a reinforcement angular part, when a rear door is closed without returning the release lever, and by loosening a control cable so as to lock a front door. CONSTITUTION:A lock release lever 1 is inserted into a guide 2 fixed to a reinforcement 4 on the rear side surface of an automatic machine box, and is energized in the direction of a front door by a control cable 3. By drawing the cable 3 to the side of a rear door, the locking of the front door is released. A rear door 5 is opened, and the lever 1 is slid, while a bent part 32 of the lever 1 is hooked on the angular part of the reinforcement 4, so as to release the locking of the front door, however, when the rear door is closed under the condition, the left end part of the lever 1 is pushed by a claw 7 mounted on the rear door 5, and the engagement between the lever 1 and the reinforcement 4 is released, and the lever 1 is drawn by the wire 3, and the front door is locked thereby. The failure in returning a lever can thus be prevented.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mechanism for unlocking a door of a housing, and particularly to an automatic financial machine in which a rear door is opened and a lock release lever for a front door is operated. Regarding the lock release lever.

[Conventional technology]

Figures 7 to 14 are diagrams showing the locking mechanism of the front door of the automatic financial machine, Figures 7 to 10 are diagrams of the locked state, and Figures 11 to 14 are diagrams of the unlocked state. It is a diagram. 7th
11 is a right side view of the front door 11, FIGS. 8 and 12 are back views of the front door 11, and FIGS.
The BB cross-sectional view in the figure, the DD cross-sectional view in Figure 12, the AA cross-sectional view in Figure 8, and the CC cross-sectional view in Figure 12, respectively.
FIG.

The front door 11 is attached to the main body of the housing by a hinge 12, and is opened by rotating in the direction of arrow A, and is mounted on a lock shaft 13.
The lower lock shaft 14 is guided by a guide 15 provided on the front door 11 and is restricted from moving up and down.

In addition, the shaft spring 16 allows the upper part of the lock shaft to
3 is constantly pulled upward, and the lower lock shaft 14 is constantly pulled downward. The lock lever 17 is guided by a pin fixed to the front door 11 opened in the lock lever 17 and engaged with the long front door 11, and is regulated to move from side to side as shown in FIG.
It is pulled to the left (outside) by 8.

When the lock lever 17 is pushed in the direction of arrow C in FIG. , the upper lock shaft 13 moves in the direction of arrow 2, and the lower lock shaft 14 moves in the direction of arrow E. As a result, from the pawl 23 protruding from the housing body to the top 1 of the lock shaft.
3. The lower lock shaft 14 comes off and the front door 11 opens.

The lock stay 19 is guided by two pins fixed to the reinforcement of the housing body that engage with the elongated hole drilled in the lock stay 19.
Slide left and right in the diagram.

Moreover, it is pulled to the right side (toward the front door) in FIG. 9 by the stay spring 20. One end of the control cable 3 is connected to the lock stay 19, and the other end of the control cable 3 is connected to the rear door (Figs. 7 to 14).
(not shown in the figure) is connected to a lever attached to the side.

When the lever on the rear door side is pulled in the state shown in FIGS. 7 to 10, the lock stay 19 slides rearward by the control cable 3 in the direction of the arrow shown in FIG. This allows the lock lever 17 to be pushed in the direction of arrow C, meaning that the front door 11 is unlocked.

(FIGS. 5 to 8) When the lever on the rear door side returns, the lock stay 19 is pulled by the stay spring 20 and returns to the state shown in FIGS. 7 to 10, and becomes locked again.

A conventional lock release mechanism is shown in FIGS. 15 and 16.

A lock release lever 9 is guided through a stopper 8 fixed to the housing reinforcement 4 through an elongated hole and an L-shaped hole, and a control cable 3 is connected to the lever 9. - It is pulled in the direction of arrow F by the force of spring 20.

To unlock the front door, pull the lock release lever 9 in the direction opposite to arrow F, hook the stopper 8 into the L-shaped hole drilled in the lock release lever 9, and unlock the front door. keep it. In order to prevent forgetting to lock the front door due to closing the rear door with the front door unlocked as shown in FIG. 16, when the lock release lever 9 is pulled and the rear door is closed, the rear door The mechanism is such that the door cannot be closed after the lock release lever 9 hits the door, making the user aware that he or she has forgotten to lock the front door.

[Problem to be solved by the invention]

With this conventional lock release mechanism, the door does not close after it hits the lever in the unlocked state, and the mechanism that makes you realize that you have forgotten to lock the front door does not apply a shock to the lock release lever when you forcefully close the rear door. giving, loosening of the stopper,
There was a problem in that problems such as bending of the lock release lever occurred.

[Means to solve the problem]

The lock release mechanism of the present invention includes a control cable whose one end is connected to the lock mechanism of the front door of the casing, and which is pulled from the other end to release the lock of the front door and loosened to lock the front door; The other end of the control cable guided by the guide is connected to a guide fixed to the main body, and when the rear door of the casing is opened, the bent part engages with the corner of the reinforcement fixed to the casing, and the control cable is connected to the guide fixed to the main body. The cable can be kept in a tensioned state, and when the rear door is closed in this state, the control cable is pushed by the tab provided on the rear door, and the engagement between the bent part and the corner of the reinforcement is released, and the control cable is pulled out. It has a lock release lever that is set in a loosened state.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the present invention.

The lock release lever 1 slides back and forth guided by a guide 2 fixed to a reinforcement 4 on the rear side of the automatic machine casing, and a force is constantly applied in the direction of the front door by a control cable 3. The control cable 3 is connected to the locking mechanism of the front door shown in FIGS. 7 to 14, and the front door is unlocked by pulling this cable toward the rear door.

In FIG. 2, first, the rear door 5 is opened in the direction of the arrow H centering on the fulcrum G on the housing side. Next, the lock release lever 1 is slid toward the rear door and the bent portion 31 formed on the lock release lever 1 is hooked onto the corner of the reinforcement 4. (Figure 4). At this time, since force is applied to the wire 3 toward the front door side, force is applied to the lock release lever 1 in the direction of clockwise rotation about the fulcrum part 6, and the lock release lever 1 is moved to the bent part 31.
The wire 3 is engaged with the reinforcement 4 at 32 and does not come off, and the wire 3 is maintained in a tensioned state by the amount of the stroke L shown in FIG.

From now on, if you close the rear door 5 without manually returning the lock release lever 1 to the state shown in Figure 2, the pawl 7 attached to the rear door 5 will open.
By pushing the left end of the lock release lever 1 in the counterclockwise direction, the lock release lever 1 and the reinforcement 4 are disengaged (Fig. 5), and the lock release lever 1 is pulled by the wire 3 to lock the front door. Return to

〔Effect of the invention〕

As explained above, in the present invention, when the rear door is closed, the lock release lever that is pulled to unlock the front door is automatically placed in the front door lock state, so the front door lock release lever This has the effect of preventing forgetting to return the door, and also prevents the lock release lever from being bent or the stopper from loosening when the rear door is closed.
