Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locker door locking device such as a rental locker or a temporary employee locker which has an unspecified number of users and an indefinite period of use.

[0002]

2. Description of the Related Art As a locking device for a metal locker that has been frequently used, a locking device and a unlocking device using a general cylindrical lock or a combination dial are known. In recent years, a format in which locking and unlocking is performed by electronic identification means such as a magnetic card has been adopted.

[0003]

When a key or a magnetic card is used as an identification means for operating the door lock, the user of the locker needs to carry the identification means, and the identification means may be damaged. A situation such as loss or theft is conceivable, and the manager needs to collect those identification means after the use period of the locker has elapsed, which is extremely complicated in management.

[0004] Locking and unlocking using a combination dial is an example of a locking method that does not require the return of a key or a magnetic card that has been used until the user stops using the lock. Even if locking or unlocking is performed by arbitrarily selecting and setting the digit number, the character string aligned for unlocking remains after opening the door, and that character string is stored by a third party. When the door is closed and locked again, the character string must be rearranged into an unrelated arrangement. This can be said to be a major drawback in a conventional combination dial type locking device.

[0005]

In a locking device using such a combination dial, in a lock having a four-digit dial, when unlocking, for example, a character string is combined with "1234" to unlock the lock. At the same time, the character string disappears and becomes, for example, “0000”, so that the door can be opened from the same state, or the character string is changed to “1” again to lock the door.
Ideally, the character string disappears at the same time when the door is closed and locked, and returns to “0000” again. in this case,
Assuming that ten characters from 0 to 9 are arranged on the dial and four dials are arranged and used, the number of combinations is 10 to the fourth power, and about 10,000 character combinations are obtained. This is enough for the number of key differences from the security aspect.

Further, in order for a new user to set his / her own character combination, if a new combination can be set only when the door is open, it is possible to obtain a functionally satisfactory device. It is.

[0007] Locking and unlocking by a combination of characters is adopted, for example, ten characters from 0 to 9 are installed on one rotatable dial, and a plurality of such dials are connected. As described above, if four such dials are provided in a row, the number of combinations of those characters becomes 10 to the fourth power,
From this, it can be seen that in a general use state, the number of dials is about three to five is sufficient.

At the same time, the dial is provided with a meshing member and a return cam on one side thereof. Both are preferably installed concentrically with the dial, the meshing member is a gear, and the return cam is preferably a flat heart-shaped one that can be returned to a fixed position by pressing both side surfaces thereof.

[0009] The same number of rotatable notch disks as the dial are meshed with the meshing member of the dial, and each disk has a notch recessed in a part thereof, and has a projection which is recessed into the notch. The hook is arranged so that when the projection enters the notch, the hook moves to control the movement of the kanuki.

[0010] The notched disk is designed to be disengaged from the dial, and a new character combination can be set in a state in which both are disengaged. Further, the kanuki controlled by the hook is driven by a handle or the like installed on the locking device.Every time the kanuki is moved, a heart-shaped cam installed on the dial is pressed,
The dial is returned to a fixed position, for example, the position of "0000" regardless of the combination character string for unlocking every time the movement of the lock for unlocking or unlocking is completed.

According to such a configuration, the combination of characters for locking and unlocking can be arbitrarily selected and set, and the combination of characters used is erased every time locking or unlocking is performed. The user only needs to perform the operation of opening or closing the door, and does not need to turn the dial each time so as not to leave his or her own combined character string.
When a large number of lockers or the like to which such a locking device is applied are installed, from the viewpoint of overall management, a structure that can be unlocked using, for example, a management key without using only combination characters is also provided. It is desirable.

In FIG. 1, reference numeral 1 denotes a casing, 2 denotes a latch bolt, 3 denotes a knuckle, 4 denotes a cam portion for operating the kanuki 3 by a key, 5 Denotes a dial member, 6 denotes a notched disk member, 7 denotes a displacement member, 8 denotes a hook, 9 denotes a canceller member, 10 denotes a kanuki fixing rod for fixing the kanuki 3 in a locked position, and 11 denotes a canceller member 9. A reset member that operates integrally with the cannula 3.

The casing 1 in FIG. 1 shows the internal structure with the back cover removed, and the shaded portion on the left side of the drawing recognizes the combined characters displayed on a part of the dial member 5. Windows are drilled. Further, a part of the kanuki 3 protrudes on the same side as the above-mentioned window, and constitutes a lever for operating the kanuki 3. Similarly, a keyhole is provided on the back surface of the casing 1 so that the cam portion 4 for operating the canker 3 by a key or the like can be operated.

Before describing the structure in detail, a general operation will be described. In the case of a locker door provided with the locking device of the present invention, when a lock is performed by a kanuki 3 entering a receiving seat, FIG. In a character recognition window on the back surface of the casing 1 of FIG. When the locker user uses his / her own combination letter, for example, "1
234 "are arranged in the window, and the operating lever protruding from the casing 1 is moved to move the kanuki 3 to the left in the figure. When the kanuki 3 is completely drawn into the casing 1, it appears in the window. The combination of the letters is returned to "0000" again.
Retreats and the door can be opened. When the door is closed, the combination characters are rearranged to "1234" again, and after the door is closed, the operating lever is moved rightward in the figure to cause the kanuki 3 to protrude from the casing and to enter the locker receiving seat. At that time, the combination character has returned to the state of “0000” again, so that it is not possible to retreat Kannuki 3 as it is, and locking is performed.

The operation related to the change of the combination character will be described. The dial member 5 is rotated by rotating the dial member 5 while the door is opened via the cam portion 4 using a key or with the correct combination character. The engaged notched disk member 6 is aligned so that it can be unlocked. Thereafter, the displacement member 7 is operated to release the engagement between the dial member 5 and the notched disk member 6, and the dial member 5 is disengaged. To the next new combination character, for example, "98
76 "is displayed in the window, and then the displacement member 7 is released, and the dial member 5 and the notched disk member 6 are collated, so that a new combination character for unlocking can be set.

The details of the structure will be described. As shown in FIG. 2, four notched disk members 6 are coaxially suspended in the embodiment, but the single
A gear 6b is integrally stacked on the disc 6a provided with a notch, a notch 6c is formed in the edge of the disc 6a, and a mark is formed on the edge of the disc 6a corresponding to the notch 6c. 6e is provided.

As shown in FIGS. 3 and 4, four dial members 5 are also coaxially suspended. As shown in FIG. 4, a single dial member 5a has a center hole 5f.
, A finger hook 5c, a gear 5b, a star-shaped gear 5d, and a heart-shaped cam 5e are integrally stacked. The gear 6b and the gear 5b of these two parts mesh with each other, and when the dial member 5 is rotated by the finger hook 5c, the notched disk member 6 is also rotated. The meshing state of these two types of members is as shown in FIG.

As shown in FIGS. 6 and 7, the canceller member 9 has the same number of click springs 9d and reset arms 9e as the dial facing the dial member 5 from the rod-shaped main body 9a having the support hole 9f. Are projected, and the support holes 9f
Is urged clockwise by a spring (not shown) or the like. Therefore, in the state where the combined characters are combined for unlocking as shown in FIG. 6, the tip of the click spring 9d is recessed into the star-shaped gear 5d of the dial member 5 to reduce the rotation of the dial 5a. At the same time, the reset arm 9e is held at a position away from the heart-shaped cam 5e.

The canceller member 9 is driven by a reset member 11 which moves together with the kanuki 3, but as shown in FIG.
When the reset member 11 moves and the drive lever 9b of the canceller member 9 is pushed up by the pressing protrusion 11b as shown in FIG.
Then, the dial 5 is returned to a predetermined position as shown in FIG. This operation is repeated when the kanuki 3 is retracted and protruded, that is, when the unlocking and locking operations are performed.

Next, a mechanism for fixing and releasing the cannus 3 will be described. The cannus 3 fixed to the reset member 11 shown in FIG. 7 through the screw holes 11a and 11a are provided as shown in FIG. It is configured. As shown in the figure, the kanuki 3 has a substantially rectangular plate shape, and has a fixing projection 3a projecting at right angles from an upper side edge in the longitudinal direction, and a projection of a cam portion 4 operated by a key on a lower side edge in the longitudinal direction. A notch 3b for receiving 4a is provided. In addition, a guide edge 3c for guiding a hook 8 to be described later is also provided on a side edge of the canker 3.

In FIG. 9, reference numeral 10 denotes a cannulated fixing rod which is rotatably pivotally attached to the casing 1 by a shaft 10a and which is rotated counterclockwise about the shaft 10a by a spring (not shown). Has been energized. Also,
A fixing step portion 10b for fixing the kanuki 3 in the locked state or the unlocked state at that position is protruded from a part of the kanuki fixing rod 10, and is further pressed by the pressing portion 4b of the cam portion 4. The pressing arm 10c to be protruded is provided.

In FIG. 9, the cannula 3 is fixed in a protruding state (locked state). The procedure for unlocking the cannula 3 with a key is as follows. Rotating clockwise, the pressing portion 4b of the cam portion 4 presses the pressing arm 10c of the kanuki fixing rod 10, and the kanuki fixing rod 10 rotates clockwise about the shaft 10a to form the fixing step. 10b is moved to a position where it does not hinder the movement of the fixed protrusion 3a of the candy cane 3, and the key is further rotated, so that the protrusion 4a of the cam portion 4 is depressed into the notch 3b of the candy cane 3. This is done by encouraging movement to the middle left.

Next, a structure for unlocking and locking using the combination dial will be described. In order to use the combined characters of the dial member 5 as the identification means for controlling the canker 3, a notched disk member 6 meshing with the dial member 5 and a hook 8 shown in FIG. 10 are used. The hook 8 is urged downward in the drawing under the action of the spring 13, and a part thereof is horizontally extended to form the fitting rod 8 a.
At the bottom, and the leading edge 3c of Kannuki 3
The guide protrusion 8b is provided to be in contact with. Further, a pressing portion 8c is provided near the guide protrusion 8b for pressing the kanuki fixing rod 10 in a clockwise direction.

The operation of the check 8 is as follows. The state shown in FIG. 11 is a state in which the notch disk member 6 meshing with the dial member 5 is in a state in which the locking by the kanuki 3 is performed and the dial member 5 is all displayed at the position of “0000”. All the notches 6c are not aligned with the fitting rod 8a of the hook 8, and the fitting rod 8a comes into contact with the edge of the notch disk member 6 and is lifted upward against the spring 13. The guide protrusion 8b at the lower end is maintained in a state of being floated near the end of the guide edge 3c of the canker 3.

FIG. 12 shows that the dial member 5 is aligned with an appropriate combination character, for example, "1234" for opening the door, and the notch 6c of the notch disk member 6 meshing with the dial member 5 is inserted into the hook 8. With the fitting rod 8a facing and aligned with the fitting rod 8a, the fitting rod 8a falls into the notch 6c by the action of the spring 13, and the depth of the notch 6c becomes deeper than the position of the hook 8 shown in FIG. The guide protrusion 8b abuts on the guide edge 3c of the canker 3,
Further, the pressing portion 8c presses the kanuki fixing rod 10 and rotates it in a clockwise direction about the shaft 10a.
0b is moved to a position where it does not hinder the sliding movement of the fixed protrusion 3a of the canker 3.

FIG. 12 shows a state in the middle of an operation for moving the cannus 3 to the unlocking position. When the cannus 3 and the reset member 11 shown in FIG. 7 are moved to the left in the figure from FIG. Then, the guide projection 8b of the hook 8 is raised by the guide edge 3c of the canker 3, and the fitting rod 8a is disengaged upward from the notch 6c of the notch disk member 6, and is returned to the same level as in FIG.
At the same time, as shown in FIG. 8 described above, the canceller member 9 is driven by the operation of the reset member 11, the reset arm 9e presses the heart-shaped cam 5e of the dial member 5, and the combined character string of the dial member 5, "123
4 ”to“ 0000 ”, so that when Kannuki 3 is completely retracted, the combination of character strings required for unlocking will not be known to the outside, and the safety of the user such as a locker will be reduced. Will be protected.

The operation of closing the door is almost the same as that in the case of opening the door. However, by appropriately designing the length of the fixed step portion 10b of the kanuki fixed rod 10, the "00"
00 ”, the door is closed and the cannus 3 can be directly locked by sliding to the locking position, or the cannus 3 is again fixed at the unlocked position by the fixing step 10b of the cannunci fixing rod 10. When locking, the character string is changed to "12
34 "and slide the kanuki 3 to enable locking.

Next, the change of the combination character string for unlocking will be described. In the set of support plates 12 shown in FIG. 14, a fulcrum hole 14, a long hole 15, a dial shaft hole 16, and a canceller shaft hole 17 are formed at the same positions. The long hole 15 has a central hole 6f of the notched disk member 6.
Is supported, and the shaft further supports the support plate 1.
2 are supported by the displacement member 7 shown in FIG. The displacement member 7 has arms 7a that support the shaft on both outer sides,
7a, a plate piece 7b connecting the same, an operation piece 7c protruding from the plate piece 7b, and a mark viewing window 7d formed in the plate piece 7b. It is pivotally attached to a fulcrum hole 14 of the plate 7. Therefore,
When the displacement member 7 is raised via the operation piece 7c, the notched disk member 6 can be moved within a range allowed by the long hole 15,
The engagement between the dial member 5 fixed to the dial shaft hole 16 and the notched disk member 6 can be released. Further, a shaft passing through the support hole 9f of the canceller 9 is suspended in the canceller shaft hole 17.

To change a combination character string, first,
Unlocking by using a key or a combination string,
When the door is opened, the viewing window 7d of the displacement member 7 is directly viewed, and the notch disk member 6 is inserted into all the viewing windows 7d.
Each dial 5a is rotated so that the mark 6e provided on the edge of the disc 6a can be seen, and the position of the mark 6e is changed. Since the mark 6e is determined in advance so as to be located at a predetermined angle with the notch 6c, the mark viewing window 7 is provided.
When the mark 6e is visible in d, the notch 6c is at a position facing the fitting rod 8a of the hook 8. Therefore, when the marks 6e are aligned as described above, the fitting rod 8a
Fits into the notch 6c and descends.

When the notch disk member 6 is fixed after the fitting rod 8a has indented all the notches 6c, the operating piece 7c of the displacement member 7 is moved upward while maintaining the state, All the notched disk members 6 supported by the arms 7a are raised together with the hooks 8 to release the engagement between the notched disk members 6 and the dial member 5. next,
The respective dials 5a of the dial member 5 are arranged in a desired new character string. For example, the character strings are aligned as in "0987", and the operation piece 7c of the displacement member 7 is released, so that the notch disk member 6 The gear 6b and the gear 5b of the dial member 5 are engaged with each other to secure the setting of a new combination character string. Thus, thereafter, the only valid character string for this lock is “0987”.

Most of the parts used in the present invention except for the cannula 3 and the reset member 11 can be made of synthetic resin.
