DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite lock device applied to a vending machine or the like.

[0002]

2. Description of the Related Art In a vending machine installed on a street or in a store where monitoring is insufficient, a pop-out type vending machine is disclosed as disclosed in Japanese Patent Application Laid-Open No. 5-263559 in order to cope with a bankruptcy that has become increasingly malicious in recent years. In addition to a lock mechanism that engages a catch plate fixed to the lock shaft of the door lock handle device with a catch on the casing side, a slide member interlocked with the catch plate is driven up and down to move the casing up and down. It has been proposed to additionally use a lock mechanism that engages with two upper and lower receiving parts on the body side.

[0003] However, even when the locking is performed at a total of three locations, the locking members at the three locations are simultaneously driven by rotating the locking shaft of the pop-out type handle device. Therefore, when the lock unit assembled to the locking shaft portion of the pop-out type lock handle device is broken or broken by a picking operation, three locks are broken at the same time.

[0004] Therefore, in order to further improve security, a sub-lock mechanism is installed adjacent to a main lock mechanism such as a pop-out type lock han device, and a control mechanism for restricting the movement of the slide member in the sub-lock mechanism. It has been proposed to link them. In such a configuration, unless the lock of the slide member is released by the auxiliary lock mechanism, the slide member cannot be moved up and down even if the locking shaft of the main lock mechanism is turned.

When the main lock mechanism and the auxiliary lock mechanism are used together,
In order to ensure convenience of use operation and management by a person in charge of replenishing goods and storing money, it is required to use a common key for the main lock mechanism and the auxiliary lock mechanism.

However, in the conventionally proposed combination of the auxiliary lock mechanism and the regulating mechanism, even if the restricting mechanism is driven by turning the locking shaft of the auxiliary lock mechanism with a key, the weight of the slide member and the frictional resistance are increased. In some cases, the slide member was not properly reset to the unlockable state.

In this case, even if a key is inserted into the main lock mechanism and the lock shaft of the main lock mechanism is turned, the slide member cannot be moved up and down to the lock position, and the door is unlocked. Will be. Therefore, the person in charge must remove the key from the main lock mechanism and insert it into the sub-lock mechanism, turn the key and try again to reset the slide member, or insert the hand into the regulation mechanism part and directly perform the reset operation. However, the complexity of the return operation in the event of malfunction was remarkable.

[0008]

In the composite lock device of the present invention thus configured, when the door 1 is closed and the lock shaft 101 of the main lock mechanism 100 is turned in the lock direction as shown in FIG. The slide member 102 descends via the arrow, and the restrained portion 103 formed in the middle of the slide member 102 pushes the passive projection 308 of the lock lever 304. Therefore, the lock lever 304 is counterclockwise viewed from the front side of the door 1 against the rotational bias in the clockwise direction viewed from the front side of the door 1 by the first toggle spring 304. Rotated. At this time, the reset lever 307 is urged to rotate counterclockwise as viewed from the front side of the door 1 by the second toggle spring 306, and the stop surface 313 of the reset lever 307 is stopped by the passive projection 308 of the lock lever 304. It is in sliding contact with the surface 310.

[0013] As shown in FIG.
Moves down to the normal lock position, and the slide member 1
02 or when the lock member separately attached to the slide member 102 engages with the metal receiving portion 3 on the fixed frame 2 side, the passive projection 308 of the lock lever 304
The tenth end 311 is engaged with the locking recess 312 of the reset lever 307. In this position, the first toggle spring 303 of the lock lever 304 is viewed from the front side of the door 1.
And the second toggle spring 306 of the reset lever 307 also acts counterclockwise when viewed from the front side of the door 1, but the second toggle spring 306 is more effective than the first toggle spring 303. Is strongly set, so that the end 3 of the passive projection 308 of the lock lever 304 is set.
11 is held in the locking recess 312 of the reset lever 307, and the lock lever 304 is moved from the front side of the door 1.
As seen , rotation in either clockwise or counterclockwise direction is prevented. Therefore, the slide member 102
Of the lock portion 304 of the lock lever 304
14 is held.

Prior to the operation of the main lock mechanism 100, the vending machine administrator unlocks the lock shaft 202 of the sub lock mechanism 200 using the key 4 common to the main lock mechanism 100 and the sub lock mechanism 200. When turned in the direction, the reset lever 307 is pulled through the interlocking member 201 as shown in FIG. 11, so that the reset lever 307 is rotated clockwise as viewed from the front side of the door 1, and The biasing direction of the second toggle spring 306 reverses clockwise as viewed from the front side of the door 1 .
By this rotation, the locking recess 31 of the reset lever 307 is formed.
The engagement between the lock lever 2 and the end 311 of the lock lever 304 is released, and the apparatus enters a reset standby state. At this stage, the hook portion 314 of the lock lever 304 is
Remains engaged with the restrained portion 103. The end of the reset lever 307 is located at the lower surface 3 of the intermediate wall of the fixed base 301.
Rotation is stopped by abutting on No. 15.

At this stage, the key 4 is extracted from the keyhole 203 of the sub- lock mechanism 200 for use in the main lock mechanism 100. This removal operation is performed by turning the locking shaft 202 of the sub-locking mechanism 200 in the opposite direction as shown in FIG. 12 and returning it to the original key insertion position. Even if the locking shaft 202 is rotated in this way, the movement is not reset lever 3
07, the reset lever 307 cannot be rotated in either direction.

Then, the key 4 extracted from the sub-lock mechanism 200 is inserted into the keyhole 108 of the main lock mechanism 100 , and
00 by rotating the locking shaft 101 in the unlocking direction.
02, the lock lever 304 is actuated.
The lock lever 304 rotates clockwise when viewed from the front side of the door 1 because the start 309 is pressed by the restrained portion 103 of the slide member 102, and the first toggle spring 30
The biasing direction of No. 3 is reversed. At the end of rotation, the end 311 of the passive projection 308 of the lock lever 304 is connected to the arc-shaped stop surface 313 of the reset lever 307 as shown in FIG.
And the lock lever 304 is held at its rotational position.

When the pulling of the slide member 102 by the operation of the main lock mechanism 100 is continued, the reset lever 307 whose pressing surface 313 is pressed by the end 311 of the passive projection 308 of the lock lever 304 is forced in the counterclockwise direction. During the rotation, the urging direction of the second toggle spring 306 reverses from clockwise to counterclockwise as viewed from the front side of the door 1 as shown in FIG. After the reset lever 307 returns to the initial position and rotates as shown in FIG. 9, the lock lever 304 is moved along the stop surface 313 of the reset lever 304 by the bias of the first toggle spring 303.
It rotates clockwise as viewed from the front side of the door 1 . When the operation projection 309 of the lock lever 304 comes into contact with the inner surface of the right wall inner surface 316 of the fixed base 301, the operation returns completely to the initial position. Thus, since the lock lever 304 is held at the position where the restrained portion 103 of the slide member 102 is released, phenomena such as insufficient release of the restraint of the slide member and re-restraint cannot occur, and stable operation can be performed.
