DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
The non-contact actuated locking mechanism, which is a feature of the bag according to the present invention, uses a well-known ID card (ID key) as a “wireless key” according to the present invention.
And just by bringing this ID card close to the locking mechanism, confirmation of the specific information stored in the ID card, turning on the operating power of the locking mechanism, locking or unlocking operation, display of the operating state, and power supply after the operation is completed A series of OFF operations are automatically performed sequentially.
[0007]
FIG. 1 shows a state in which the locking mechanism A of this embodiment is attached to a bag (a suitcase or the like) as a longitudinal sectional view of a main part.
B1 in the figure is a side wall on the body side of the heel, and B2 is a side wall on the lid side. C is a handle of the bag and is assembled so as to straddle the handle base 10.
The left and right side ends of the handle base 10 are each provided with a lid lock mechanism D having a length reaching the side end of the side wall B1.
[0008]
As shown in FIG. 1, the locking mechanism A is assembled across the box-shaped handle base 10 and the drive unit case 20 provided below the bottom wall surface.
E in the figure is a power supply battery for operating the locking mechanism A.
[0009]
In the handle base 10, an antenna substrate F is housed as specific information identification means for determining whether or not the ID information from the ID card approaching the locking mechanism A is the same as the predetermined information.
Further, a mechanical unlocking (and locking) means G for use when the locking mechanism A malfunctions due to, for example, the power battery E being consumed while being locked is also assembled.
[0010]
Since the lid lock mechanism D of this embodiment has a known structure, its structure will be schematically described. The frame 1 having a length extending from both side ends of the handle base 10 and reaching the end of the side wall B1 is attached to the side wall. It is attached to B1.
A lock bar 2 for closing the lid is assembled to the frame 1 so as to be movable along the frame 1 from side to side (the same applies in the drawings). The lock bar 2 is divided into a plurality of portions in the longitudinal direction for convenience of assembly and the like.
[0011]
At the front end of the lock bar 2 (both ends of the side wall B1), a hooking claw 4 is provided for engaging with the hole edge of the hooking hole 3 provided in the side wall B2 on the lid side.
The proximal end side of the lock bar 2 extends to the inner space of the handle base 10.
The lock bar 2 is normally urged forward by a spring 5 in the distal direction, so that the latching claw 4 engages with the latching hole 3 and the lid closed state is locked.
Reference numeral 6 denotes a push button for unlocking.
[0012]
As shown in FIGS. 2, 3 and 7, 8, a pair of left and right strip-shaped lock bars 2, 2 has a certain gap a between their base ends in the handle base 10. They are arranged so as to face each other.
And the guide rail 2a is formed by bending the base end part of the lock bar 2 upward, as shown in FIG.
[0013]
The slider 7 is loosely fitted to the guide rail 2a so as to move back and forth along the rail. In this loose fitting state, a part of the slider 7 protrudes somewhat toward the gap a (see FIG. 6).
As shown in FIGS. 2 to 4, a guide plate 8 is brought into sliding contact with the side surface of the slider 7 opposite to the protruding side.
Furthermore, a small groove 7a is provided on the upper surface of the slider 7 so as to be orthogonal to the guide rail 2a (see FIG. 6).
[0014]
Further, as shown in FIGS. 6 to 8, the bottom surface of the handle base 10 has two communicating portions in the drive unit case 20 at a gap a between the left and right guide rails 2 a and 2 a. The through holes 9, 9 are provided in a positional relationship that is shifted in the front-rear direction.
[0015]
In the handle base 10, in order to operate the lock, an antenna board having a function of determining whether the ID information (specific information) of the ID card brought close to the locking mechanism A is the same as the predetermined specific information (specific (Information identification means) F (see FIG. 1).
[0016]
As shown in FIG. 9, for example, the antenna substrate F includes an antenna 11 for reading ID information, a discrimination circuit for discriminating whether the read ID information is the same as predetermined ID information, and In addition, an LED (operating state display means) 12 for displaying whether the locking mechanism A is in the locked or unlocked operating state is assembled.
[0017]
As shown in FIG. 1, the drive unit case 20 includes a locking member 21 for locking, which prevents the pair of left and right lock bars 2 and 2 from moving backward and keeps them locked. A lock actuating means H that allows the guide rails 2a and 2a to be moved in and out toward the gap a, a control board J (operation control unit) that controls the operation of the locking mechanism A, and a locking / unlocking mechanism. An operating state detection unit K that detects which state is present is incorporated. w is a wiring.
[0018]
As shown in FIGS. 5 and 6, the locking lock member 21 is provided with a protruding piece-like stopper 21 b extending upward on each of the right end on the front edge side and the left end on the rear edge side of the horizontal substrate 21 a. It has the form.
The locking lock member 21 is pushed up during locking, and as shown in FIGS. 4 and 6, the stopper 21b passes through the through hole 9 on the bottom surface of the handle base 10 and protrudes into the gap a. As shown in FIG. 3, the drive unit case 20 is retracted.
[0019]
As shown in FIGS. 3 to 6, the lock actuating means H that controls the above-described operation of the locking lock member 21 is a motor with a speed reducer mounted sideways on the bracket 22 as shown in FIGS. 3 to 6. 23 and an eccentric rotating cam 24 fitted to the output shaft 23a.
The locking lock member 21 is assembled to the bracket 22 in a state where it is pressed against the upper surface of the eccentric rotating cam 24.
[0020]
Further, as shown in FIG. 1, a rotary plate 25 is fitted on the tip of the output shaft 23a of the motor 23, and the rotation position sensor 26 detects the rotation position.
The rotary plate 25 and the rotation position sensor 26 constitute a lock operating state detection unit K.
[0021]
When the ID information identification signal is input from the antenna substrate F to the control board J housed in the drive unit case 20, the power switch of the power battery E is turned on, and the switch is turned off when a predetermined time elapses. A power interrupt circuit (not shown) is incorporated for operation.
An operation control circuit for the motor 23 is incorporated to rotate the eccentric rotary cam 24 by a predetermined angle each time an identification signal is input.
[0022]
Next, the structure of the mechanical unlocking means G of this embodiment will be described with reference to FIGS.
The main body of the mechanical unlocking means G is a small cylindrical unlocking member 30, as shown in FIG. 3, so that it can be rotated around its axis at a position immediately above the gap a. The handle base 10 is assembled.
[0023]
As shown in FIG. 7, a groove 30 a having a predetermined width and depth is provided on the top surface of the unlocking member 30 to manually rotate the member.
If the edge part of ID CAD etc. is inserted in this groove | channel 30a, the member 30 for unlocking can be turned.
[0024]
On the bottom surface of the unlocking member 30, projections 30 b are respectively projected downward at both ends of the diameter line.
As shown in FIG. 7, the one set of protrusions 30b and 30b is formed in a small groove 7a of the slider 7 on the guide rail 2a provided at each base end of the one set of lock bars 2 constituting the lid lock mechanism D. It is provided in an arrangement that can be loosely fitted.
[0025]
Next, the operation of the locking mechanism A will be described.
The locking mechanism A cannot be operated unless the ID information recorded on the ID card used instead of the conventional key matches the ID information stored in the locking mechanism A.
[0026]
The locking / unlocking method is as follows. When an ID card (not shown) held in the hand is brought close to the locking mechanism A, the ID stored in the board by the antenna board F provided with the antenna 11 for detecting ID information. It is determined whether the information matches that of the ID card.
[0027]
When both pieces of ID information are identified, first, as a first operation stage of the locking mechanism A, this identification signal is input to the power supply interrupt circuit of the control board J, and the power switch of the power battery E is turned on.
Then, the rotation position sensor 26 detects whether it is locked or unlocked, and causes the LED 12 to emit light in red (locked) or green (unlocked) color. The reverse is also possible.
[0028]
In the unlocked state, the eccentric rotating cam 24 is in the rotational position shown in FIG. 3, and the stopper 21 b of the locking lock member 21 is drawn into the drive unit case 20.
[0029]
When it is desired to lock the lock, if the LED 12 emits green light in the first operation stage, the lock of the bag is not locked, so that the ID card is kept close to the lock mechanism A.
Then, the locking mechanism A moves to the second operation stage, and an identification information identification signal is input to a lock operation circuit (not shown) of the control board J.
[0030]
Accordingly, the motor 23 rotates the eccentric rotary cam 24 by 180 degrees to displace it from the position shown in FIG. 3 to the position shown in FIGS.
Therefore, the locking lock member 21 is pushed up, and the pair of stoppers 21b and 21b passes through the through hole 9 provided in the bottom surface of the handle base 10 as shown in FIG. Protrusively at the point.
[0031]
The protruding stoppers 21b and 21b are in contact with the side surface of the slider 7 assembled to the guide rail 2a at the base end of the lock bar 2 (see FIG. 6).
Therefore, the lock bar 2 that is normally urged forward by the spring 5 and occupies the lid lock position cannot be moved backward against the urging force of the spring 5.
That is, the locking mechanism A is locked. Locking can be confirmed by changing the emission color of the LED 12 from green to red.
[0032]
When a predetermined time elapses after the locking operation, the power switch of the power battery E is automatically turned off by the timer function provided in the power interrupt circuit, thereby preventing wasteful consumption of the battery.
[0033]
Next, in order to unlock the locking mechanism A in the locked state, the ID card is moved closer to the locking mechanism A as in the locking operation.
Then, first, after the power switch is automatically turned on, the motor 23 operates to rotate the eccentric rotating cam 24 by 180 degrees.
[0034]
Along with this, the stopper 21 b pressed and biased by the eccentric rotating cam 24 moves downward and retracts below the through hole 9.
Therefore, if the push button 6 is pushed to open the lid of the bag, the lock bar 2 can be moved backward without any trouble. That is, the locking mechanism A is unlocked.
[0035]
Next, the operation of the mechanical unlocking means G will be described with reference to FIGS.
It cannot be said that the electric locking mechanism A remains locked and the power supply battery E is exhausted or the locking mechanism A itself is malfunctioning.
[0036]
In such a case, the edge of the ID card is inserted into the groove 30a on the top surface of the unlocking member 30 exposed on the upper surface of the handle base 10, and the unlocking member 30 is turned counterclockwise. Rotate in the direction.
As shown in FIG. 7, each of the set of protrusions 30b protruding from the lower surface of the unlocking member 30 is loosely fitted in the small groove 7a of the set of sliders 7, so that As the member 30 is rotated, the pair of sliders 7 are moved in opposite directions along the guide rail 2a as shown in FIG.
[0037]
By this movement, both the sliders 7 are released from a state where they are in contact with the stopper 21b of the locking lock member 21 (see FIG. 8).
Therefore, even if the stopper 21b protrudes into the area of the gap a, if the push button 6 is pressed, both the lock bars 2 are retracted without any trouble, and the locked state of the lid can be released.
[0038]
The “wireless key” necessary for locking / unlocking the locking mechanism A is not limited to the ID card (ID key).
That is, it suffices if the key is configured so that specific information (ID information) recorded on the key can be called by irradiating the key with various electromagnetic waves such as radio waves, infrared rays, and ultrasonic waves.
And, the form of the key is not necessarily a card form.
[0039]
The specific structure of the lock actuating means H, the mechanical unlocking means G, etc. is not limited to the above embodiment, and various design changes can be made by changing the combination of various known mechanical elements. is there.
[0040]
【The invention's effect】
As is clear from the above explanation, the bag equipped with the non-contact operation type locking mechanism according to the present invention is inserted and turned around the key hole of the lock every time locking and unlocking is performed, and the dial numbers are adjusted. Compared with the conventional bag that requires a lot of troublesome operations such as the above, the following practical advantages can be obtained. (1) A wireless key such as an ID card in place of a conventional plug-in key Can be locked or unlocked simply by moving the key closer to the locking mechanism, and the operation is extremely simple.
(2) The power supply battery of the locking mechanism can be automatically inserted just by bringing the ID card closer.
(3) However, since the power is automatically turned off when the locking / unlocking operation of the locking mechanism is completed, it is possible to prevent wasteful consumption of the battery.
(4) Since there is no need to insert the key into the key hole, it can be locked and unlocked very easily even for persons with disabilities and the elderly.
(5) Even if the battery is consumed in the locked state, it can be easily unlocked (locked) by the mechanical unlocking means having a simple structure.
(6) A wireless key such as an ID card can be easily increased almost infinitely, unlike a mechanically operated key.
