Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a solenoid-operated door locking device used in paid lockers installed in station premises and the like.

(Prior art) In conventional paid lockers, coin slots are individually provided in the fixed frame surrounding the box-shaped goods storage section, and coins inserted through the slots are sorted by type using a coin sorter. When the amount was measured and coins of the correct amount were inserted, an unlocking signal was sent electrically or mechanically to the lock that locks the door of the goods storage section to the fixed frame, and the coin was received. Coins are stored in a coin storage container provided in the fixed frame portion.

(Problem to be Solved by the Invention) Since this coin storage container is individually fitted with a lock such as a pin tumbler lock in the axial direction, in conventional paid lockers, two locks are attached to one article storage section.
It was necessary to install multiple locks, which was expensive in terms of cost.

In addition, in order to prevent coins from being stolen from the coin storage container by illegally unlocking the lock with a picking tool, etc., it is necessary to constantly monitor the location where the lock is installed in each article storage section. It is practically impossible to monitor all the locks of the article storage compartments arranged in the same manner from the viewpoint of personnel allocation, and it is not cost-effective to monitor them using mechanical equipment such as monitor televisions.

A method for stealing coins with the minimum amount of efficient staffing and monitoring equipment is to provide a place to insert money such as coins only on the remote control machine installed in each paid rental locker. A method is proposed in which the money storage container is limited to one location.

In this remote-controlled pay rental locker, when a user inserts a predetermined amount of money into the operating machine, a card displaying the compartment number of the storage compartment designated by the user and the code number for unlocking is operated. At the same time, the door of the designated article storage section is electrically unlocked.

The user goes to the article storage section of the designated section displayed on the card, stores the articles such as baggage, and then closes the door and performs a predetermined locking operation. When taking out an article, the user inputs a specified password number by operating the keys on the operating device, and sets the locking device of his/her article storage section to an unlocking standby state. Thereafter, the user goes to the article storage section and performs a predetermined unlocking operation to open the door.

An object of the present invention is to provide a solenoid-operated door locking device that is most suitable for use in such remote-controlled pay rental lockers.

(Function) For example, when used as a locking device for a remote-controlled paid rental car, when the user inserts the specified amount of money or inserts a prepaid card into the remote-controlled operating device, the compartment number of the goods storage section and the recited number are displayed. The card displaying is taken out from the operating machine, and at the same time, the locking device of the present invention attached to the designated article storage section becomes electrically usable.

When the user goes to the article storage section in the designated compartment and operates the door opening switch 9, the solenoid 3 is energized and the plunger 20 is driven backward. Accordingly, the control lever 22 is moved to the stop lever 2.
2 and pull down the stop bar 22 to release the restraint of the drive cam 15 by the stop lever 22. Therefore, the thumb turn 8 resists the rotational bias of the spring 17.
When the operation panel 6 is rotated in the opening direction, the cam operating pin 7 pushes the drive cam 15, and the drive cam 15 pulls the dead bolt 14 into the door unlocked position in the case 2.

At the end of the retraction operation of the dead bolt 14,
As shown in FIG. 6, the stop lever 18 engages the deadbolt 14 and restrains the deadbolt 14 in the unlocked position. This engagement between the stop lever 18 and the dead bolt 14 is precisely maintained by a spring 19. The user opens the door 12 that has been unlocked in this manner, stores items such as baggage, and then closes the door 12.

When the door 12 is completely closed, the door closing confirmation switch 25 is operated and the solenoid 3 is energized.
Plunger 20 is driven forward. Accompanying this, the operation bar 21 pushes up the stop bar 18 and releases the dead bolt 14 from being restrained by the stop bar 18. When the dead bolt 14 is released from the restraint in this manner, the drive cam 15 is automatically rotated in the locking direction by the bias of the spring 17, and drives the dead bolt 14 to protrude to the locked position.

As shown in FIG. 5, when the tip of the dead bolt 14 engages with the receiving part 13 on the door 12 side,
is locked to the fixed frame 1 again. Following the forward movement of the operation bar 21, the stop bar 22 is rotated by the bias of the spring 23, and is always in contact with the stop bar 22 and the operation bar 21.
At the end of the forward movement of the stop bar 22, the drive cam 15

Here, when the thumb turn 8 is turned slightly in the locking direction against the bias of the spring 16 and the control switch 24 is pressed with the cam operating pin 7 of the operation panel 6, the plunger 20 of the solenoid 3 pushes up the stop bar 18. is held in the forward position. thumb turn 8
When the finger is released, the operating panel 6 rotates in the opposite direction due to the bias of the spring 16, and the cam operating pin 7 and the drive cam 15 are brought into contact with each other again.

When the user returns to the location where the paid rental locker is installed and retrieves the item, the user inputs the designated recitation number by operating keys on the keyboard of the operating device. As a result, the locking device of the article storage section to be opened is electrically set to an unlocking standby state by remote control. Thereafter, the user presses the door opening switch 9 in the same manner as described above and turns the thumb turn 8 in the opening direction to open the door 1 by the dead bolt 14.

When unlocking the door 12, the drive cam 15 is restrained by the stop lever 22 by simply pressing the door open switch 9 after inputting and setting the operating device to the unlock standby state according to a predetermined procedure. Once released, the drive cam 15 pulls the dead bolt 14 into the unlocked position simply by turning the thumb turn 8, and the door can be unlocked easily without a key.

In addition, the fixed frame 1 and door 12 are not equipped with any key locks or money storage containers, so unlike conventional paid rental lockers, lost keys, stolen keys, or illegally duplicated duplicate keys cannot be used. There is no risk of unauthorized access to the goods storage section or money storage container.

Further, in the locking device of the present invention, unless the door 12 is completely closed, the closing confirmation switch 25 is not operated and the plunger 20 of the solenoid 3 is not driven forward, so the restraint of the dead bolt 14 by the stop lever 18 is not released. Therefore, rotate the thumb turn 8 in the locking direction and remove the dead bolt 1.
Even if an attempt is made to project the door 4 to the locked position, such rotational operation is impossible and the door 12 cannot be locked. In this way, the thumb turn 8 cannot be rotated unless the door 12 is fully closed, so unlike conventional devices that allow the door to be locked even when it is open, the door may be left partially open under the illusion that it is locked. There is no need to worry.
