DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention is used for cash bags used in banks and the like, and can be easily opened and closed.
The present invention relates to a cash bag lock device that cannot be opened unless the user is familiar with the structure.

[0002]

2. Description of the Related Art In a conventional cash bag lock device, two lock plates provided with lock portions for engaging and disengaging a lock portion of a lock bolt at a tip end thereof are rotatably pivoted to a case, and a base of the lock plate is provided. The release plate whose base end is in contact with the end is slidably housed in the case, and the lock bolt and lock plate are disengaged by a shape memory spring that does not work at room temperature but functions at high temperatures. The release plate was urged.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cash bag provided with a safety device so that cash can be easily taken in and out, cannot be opened or closed unless the structure is understood, and furthermore, it is not intentionally opened and closed. To provide a locking device.

[0005]

The cash bag lock device according to the present invention will be described below with reference to the reference numerals in the accompanying drawings. In the cash bag lock device, a case 4 fixed to a cash bag 1; A lock portion 5b is provided at an intermediate portion, and a lock bolt 5 fixed to the lid 2; and a lock portion 6a, 7a which is engaged with and disengaged from the lock portion 5b of the lock bolt 5 at the tip portion is slidably housed in the case 4. Lock plates 6 and 7 whose base ends are rotatably pivotally connected to the released release block 14; long holes 6b and 7b provided at the intermediate portions of the lock plates 6 and 7 are pivotally attached to the intermediate portion so as to be slidable and rotatable. A release plate 10 slidably housed in the case 4; and a plunge 11a fixed to the case 4 and abutted on the base end of the release plate 10 by energizing an electric terminal 16 fixed to the case 4. With the solenoid 11 popping out; A spring 12 for urging the release plate 10 in the direction of contact with the plunge 11a and for urging the release block 14 in the opposite direction; an upper surface abutting on the tip of the lock bolt 5 and being urged upward by the spring 22 A hook guide 21; and a cylinder unit 1 fixed to the cover 3.
Cylinder cam 1 that is fixed to the tip of the cylinder unit 3 and slides the release block 14 by rotation of the cylinder unit 13
5, a lock pin 17 whose distal end fits into a through hole 10a provided in the release plate 10 and is urged by a spring 19 in the fitting direction; and a distal end fits in a through hole 10b provided in the release plate 10. The magnet pin 2 is biased by the spring 20 in the fitting direction, and is provided with the inclined portion 28a at the distal end in the releasing direction.
And a lock pin 18 which is urged by the magnetic repulsion force of the lock member 18.

When the cash bag is opened, the lock pin 17 is pulled down by the magnet against the spring 19 to release the engagement of the release plate 10 with the through hole 10a, and similarly, the magnetic repulsion between the magnet and the magnet pin 28 is performed. When the lock pin 18 is pushed up by the force to release the engagement of the release plate 10 with the through hole 10b, the restraint of the release plate 10 on the case 4 is released. When a predetermined electric terminal 16 is energized, the plunge 11 a jumps out of the solenoid 11 and pushes the release plate 10 against the spring 12. Then, since the long holes 6b and 7b of the lock plates 6 and 7 pivotally attached to the release plate 10 are pushed toward the base end, the lock plates 6 and 7 rotate around the long holes 6b and 7b and move to the front end. Is opened, the engagement between the lock portion 5b of the lock bolt 5 and the lock portions 6a, 7a of the lock plates 6, 7 is released, and the lock bolt 5 is pushed out by the hook guide 21 urged by the spring 22, and the cover 2 Is released.

Further, the cylinder unit 13 is rotated, the cylinder cam 15 is rotated, and the release block 14 is slid against the spring 12. Then, since the base ends of the lock plates 6 and 7 pivotally attached to the release block 14 are pushed in the direction of the distal end, the lock plates 6 and 7 rotate around the elongated holes 6b and 7b. Similarly, the lid 2 can be opened.

When the cover 2 is closed, first, the inclined portion 5a at the tip of the lock bolt 5 fixed to the cover 2 comes into contact with the lock portions 6a, 7a of the lock plates 6, 7, and thereafter, the lock plates 6, 7 It opens against the spring 12 while slidingly contacting the inclined portion 5a. Further, the tip of the lock bolt 5 contacts the upper surface of the hook guide 21 and closes the lid 2 against the spring 22. Lock part 6 of lock plates 6 and 7
When a and 7a reach the lock portion 5b of the lock bolt 5,
The lock plates 6 and 7 are closed, the lock portions 6a and 7a and the lock portion 5b are engaged, and the lid 2 is closed.

The release plate 14 is pivotally connected to the release block 14, and the long holes 6b, 7b provided in the intermediate portions of the lock plates 6, 7 are slidably and rotatably connected to the intermediate portion of the release plate 10, and the release plate 10 is slid. The release plate 10 is housed in the case 4 as much as possible, and the power is supplied to the electrical terminals 16 fixed to the case 4.
A spring 12 for urging the release plate 10 in the direction of contact with the plunge 11a and urging the release block 14 in the opposite direction is secured to the case 4 by fixing the solenoid 11 from which the plunge 11a abutting on the base end of the plunger 11a protrudes. By mounting the hook guide 21 whose upper surface contacts the tip of the lock bolt 5 and is urged upward by a spring 22, the electric terminal 1
The cover 2 can be easily opened only by supplying electricity to the cover 6.

The lid 2 can be manually opened by fixing a cylinder cam 15 which slides the release block 14 by rotating the cylinder unit 13 to the tip of the cylinder unit 13 fixed to the cover 3.

The distal end of the lock pin 17 is fitted into the through hole 10a formed in the release plate 10, and the spring 19 is moved in the fitting direction.
And the leading end of the lock pin 18 is fitted into the through hole 10b provided in the release plate 10, and the spring 2 is moved in the fitting direction.
0, and is urged by the magnetic repulsive force of the magnet pin 28 provided with the inclined portion 28a at the distal end in the release direction, so that the structure is well understood, and the magnets lock the lock pins 17, 18 and the release plate 10 with each other. Unless the fitting is released, the lid 2 cannot be opened. Further, since the lock pin 17 is fitted from below the release plate and the lock pin 18 is fitted from above, the fitting is not released by vibration or the like.
