Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a rental locker lock device in which a key is lent by inserting a coin into a coin slot, and a cylinder lock exclusively for a user in a locked state is provided. The present invention relates to a lock device for a rental locker, which enables an administrator to unlock a door of a rental locker by using a master key without unlocking and opening and closing the door.

[Prior Art] There are roughly two types of so-called rental locker lock devices, one of which is a leisure-type device installed in a pool and the other is a terminal installed at a station. There are types of devices.

The leisure type is limited to use for only one day, while the terminal type allows use for several days.

Also, as an emergency unlocking device or emergency unlocking device provided in the leisure type, for example, in the emergency unlocking device,
Publications 56-46434, 58-27456, 60-158279 and 61-27034 are published as publications.

Further, Japanese Utility Model Laid-Open No. 61-37585 has already existed as a device in which a locking rod can be moved in either direction of locking or unlocking by using a master key. This real Kaisho 61
In No. -37585, when the rental locker is in use, that is, when the key to be rented is removed from the cylinder lock, the rotor inside the cylinder lock into which this key is inserted and removed is in a state of being unable to rotate. That is, when the key is removed from the cylinder lock, the tumbler embedded in the rotor is biased by the spring and locked in the groove in the case, and the rotor cannot rotate. When moving the rod in the direction of locking or unlocking, one condition must be provided for the device.

Therefore, it is necessary to allow the locking rod to move freely by allowing the rotor to rotate even during locking, that is, even after the key is removed from the cylinder lock. However, as mentioned above, after the key is removed from the cylinder lock, the tumbler inside the cylinder lock is locked in the concave groove formed in the case of the cylinder lock, so move the locking rod by operating the master key. You cannot do it.

In the disclosed Japanese Utility Model Publication No. 61-37585, the intended purpose cannot be achieved unless such a point is solved.

[Problems to be Solved by the Invention] In the former lock device for a locker for lending, since the master key can only unlock the locker in an emergency, the opening / closing door once opened can be used as a locker for lending. Since the person is in the unlocked state until the person returns, there is a trouble that the administrator has to carry the luggage separately to the storage room in order to preserve the luggage. Also, in the latter lock device of the rental locker, to unlock the locking rod by immersing the locking rod with the master key without unlocking the cylinder lock dedicated to the user in the locked state, A mechanism for temporarily disconnecting the connection with the locking rod is provided, or the entire cylinder lock exclusively for the user in the locked state can be temporarily turned to rotate in the unlocking direction and then the entire cylinder lock is retired. It is necessary to restore the state, which causes a problem that the internal structure of the lock device becomes complicated and a problem that operation becomes complicated.

The object of the present invention was made in view of such drawbacks, and even while the user-only cylinder lock is being locked,
With a simple operation to operate the cylinder lock exclusively for the administrator, the lock device of the rental locker can be unlocked by retracting the locking rod without affecting the cylinder lock exclusively for the user. It is provided.

[Means for Solving the Problems] In order to achieve such an object, the present invention has at least a locking rod protruding and retracting from a channel-shaped frame body, a cylinder lock dedicated to an administrator on the front surface of the frame body, and a rental. In a lock device of a locker for rent having a locker user-dedicated cylinder lock, a coin slot for inserting coins, and a coin return port for returning coins, a cylinder lock pivotally attached to the frame body and dedicated to the manager. Cam member fixed to the rotor of the above, and an up-and-down moving plate that engages one end with the cam member and moves upward and downward with the rotation of the cam member by locking and unlocking the cylinder lock dedicated to the manager. And, pivotally attached to a shaft provided in the frame, one end is in an engaging state with a gap in the vertical moving plate, and the other end has an engaging pin for driving the locking rod in the retracted direction, Vertical movement of the vertical movement plate The drive plate that rotates between the locking angle and the unlocking angle with the rotor is fitted into the rotor of the cylinder lock dedicated to the user, and the rotation that rotates between the locking angle and the lock angle by operating the cylinder lock dedicated to the user. The rotary plate is formed with a notch hole into which the engaging pin engages, and the notch hole is provided with the engaging pin when the rotary plate is at a locking angle. It is characterized in that an opening capable of engaging and disengaging is provided.

[Operation] The lock device of the locker for rent according to the present invention will be described in the order of the locked state, the unlocking operation and locking operation by the customer-dedicated cylinder lock, and the emergency unlocking operation and locking operation by the administrator-dedicated cylinder lock.

In the cylinder lock exclusively for users, in the locked state where the key is removed, the rotating plate and the drive plate are at the lock angle, the locking rod pushed by the engagement pin of the drive plate protrudes, and it engages with the locker body. I can't open the locker door.

The cylinder lock exclusively for the administrator is usually in the locked state,
Since the vertical moving plate is in the raised position, the vertical moving plate is provided with a gap that allows one end of the drive plate to rotate only in the unlocking direction.

When the drive plate is at the locking angle and the rotating plate is at the locking angle, the engagement pin is engaged with the cutout hole and is in a position where it can be disengaged from the opening.

When the key is inserted into the cylinder lock exclusively for customers and the unlocking operation is performed, the rotating plate rotates to the unlocking angle, and the drive plate pressed by the engaging pin on the rotating plate rotates to the unlocking angle in the same direction. The locking rod that moves and engages with the engaging pin can be retracted to open the door.

When the drive plate is rotated to the unlocking angle, a gap is formed in the up-and-down moving plate that allows one end of the drive plate to rotate only in the locking direction, and the engaging pin is located in the notch hole. It moves to a position where it cannot be separated from the opening.

From such an unlocked state, when the locking operation is performed with the cylinder lock exclusively for the customer, the rotating plate rotates to the locking angle,
Since the engaging pin is in a position where it cannot be removed from the opening of the cutout hole, the drive plate rotates together with the rotating plate to the locking angle, and the locking rod pushed by the engaging pin projects to return to the locked state.

When the drive plate returns to the locking angle, the engagement pin returns to the position where it can be disengaged from the opening of the rotating plate having the locking angle.

Next, the emergency unlocking by the cylinder lock dedicated to the administrator will be described when the cylinder lock dedicated to the customer is locked and the key is removed.

Insert the parent key only owned by the administrator into the cylinder lock dedicated to the administrator, and unlock it to lower and move the vertical plate.
The drive plate whose one end is pushed by the vertical moving plate is pushed in the unlocking direction, the engaging pin at a position that can be disengaged from the opening disengages from the opening of the notch hole, and the drive plate rotates to the unlocking angle. , The locking rod is immersed.

Since the rotating plate is stopped at the locked angle, the cylinder lock dedicated to the customer remains in the locked state.

When the drive plate reaches the unlocking angle, a gap is formed in the vertical moving plate that allows one end of the drive plate to rotate only in the locking direction.

Next, when the cylinder lock dedicated to the administrator is used for locking operation, the vertical moving plate rises, the drive plate whose one end is pushed by the vertical moving plate rotates in the locking direction, and the engaging pin projects the locking rod. , And returns to the inside of the cutout hole of the rotating plate via the opening.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In the figure, FIG. 1 is a rear view of the lock device A of the present invention, and FIG. 2 is a front view. FIG. 2 shows a cylinder lock 2 dedicated to the administrator and a cylinder lock 3 dedicated to the user of a rental locker (not shown) on the front of the channel-shaped frame 1.

A return port 5 is provided. The coin insertion port 4 and the coin return port 5 are connected to the coin guide passage 16.

Reference numeral 6 denotes a cam member which is fixed to the rotor 2'of the cylinder lock 2 exclusively for the administrator and which rotates with the rotation operation of the master key (not shown) by the administrator. When mounting the lock device A on the rental locker main body (not shown), one end 6a of the cam member 6 is exposed to the outside of the frame 1 and locked to the rental locker main body. Further, the pin 7 is planted at the other end 6b. The pin 7 is engaged with a notch hole 8'formed at the end of the vertical moving plate 8. Further, below the vertical moving plate 8, there is formed a fitting hole 8c with which a flange portion (not shown) formed on the rotor 3'of the cylinder lock 3 is engaged and disengaged. Further, when the vertical moving plate 8 moves in the vertical direction, a long hole is formed in the vertical moving plate 8 so that the movement is stable.
8d, 8e, 8f are formed respectively, and guide pins are inserted in these long holes 8d, 8e, 8f.
Insert 9a, 9b, 9c.

Also, in order to prevent the vertical moving plate 8 from being unintentionally detached from the guide pins 9a, 9b, 9c, the E-ring 10a, is attached to the guide pins 9a, 9b, 9c.
Fit 10b and 10c respectively.

Standing pieces 8a, 8b are provided on the vertical moving plate 8 so as to project at two positions with a space therebetween, and one end of a drive plate 11 pivotally mounted on a support shaft 15 between the standing pieces 8a, 8b. Face 11a. At the other end 11b of the drive plate 11, an engagement pin 12 which is engaged with a notch hole 13 'of the locking rod 13 is planted.

The engaging pin 12 is a notch hole formed at one end of the rotating plate 14 into which the rotor 3'of the user-specific cylinder lock 3 is fitted.
Located within 14a. As shown in FIG. 1, when the rotary plate 14 together with the rotor 2'is at the locking angle, the drive pin 12 moves the locking rod 13 in the recess 14a in the recessed direction (counterclockwise direction in FIG. 1). An opening 14d through which the engaging pin 12 is disengaged is provided so as to be rotatable. In the figure, 17 is a coin operating finger, and 18 is a locking rod 13 fixed to the frame 1.
It is a guide fixing piece.

FIG. 3 shows another embodiment relating to the engaging relationship between the vertical moving plate 8 and the driving plate 11, which is a long hole in which the pin 19 which is planted in the vertical moving plate 8 is bored at the end 11a of the driving plate 11. 11c is engaged and the drive plate 11 is rotated.

When the cylinder lock 3 is rotated from the unlocking angle to the locking angle by the user's key, the rotating plate 14 rotates in the clockwise direction, and at this time, the end portion 14b of the notch hole 14a of the rotating plate 14 is rotated. While engaging with the engaging pin 12, the engaging pin 12 is rotated in the clockwise direction, so that the drive plate 11 is also rotated and locked.

In order to unlock, the key is rotated in the opposite direction, that is, the unlocking direction, so that the engagement pin 12 causes the rotation plate 14 to rotate.
Since it is reversed together with the drive plate 11 in the counterclockwise direction while contacting the inner peripheral surface 14c of the cutout hole 14a, the locking rod can be moved in the unlocking direction.

Next, when the user is using the rental locker, that is, when the key is removed from the cylinder lock 3 of the lock device A, when an emergency occurs and unlocking is required,
When the administrator inserts a master key (not shown) into the cylinder lock 2 exclusively for the administrator and rotates the cam member 6, the vertical moving plate 8 having one end engaged with the pin 7 of the cam member 6 descends. Therefore, one of the upright pieces 8a of the vertical moving plate 8 drives the drive plate.
Reverse 11 in the counterclockwise direction, that is, in the unlocking direction. Since the rotating plate 14 is at the locking angle, the engagement pin 12 is disengaged from the notch hole 14a through the opening 14d by reversing the unlocking direction of the drive plate 11, and the cylinder lock 3 for the user is locked. The locking rod 13 can be moved in the unlocking position direction while being locked.

In addition, the administrator must lock the open / close door in order to continue storing the luggage again after checking the luggage in the stored locker.

Therefore, when the administrator rotates the cam member 6 in the opposite direction by using the master key, the vertical moving plate 8 is lifted by the pin 7 of the cam member 6. When the up-and-down moving plate 8 rises in this way, the other upright piece 8b of the up-and-down moving plate 8 pushes up the drive plate 11, so that the drive plate 11 rotates in the clockwise direction, that is, in the locking position direction. .

In this way, when the drive plate 11 rotates, the locking rod 13 moves in the locking direction and the locking is completed.
