Abstract

<P>PROBLEM TO BE SOLVED: To enable the number search of a dial lock to be performed easily from the front side of the lock using a spare key. <P>SOLUTION: The number of the dial lock 1 is set to be an intended unlocking number in the door-opened state where a hook arm 4 is housed. A finger grip 2 is turned and the hook arm 4 is engaged with a hook receiving hole of a locker body to obtain a door-closed state. When the number of the dial lock 1 is changed, the locked state is obtained where the finger grip 2 can not be turned. When the number of the dial lock 1 is tuned to the unlocking number in the locked state, a door-closed state is obtained where the finger grip 2 can be turned. When a user forgets the unlocking number, a cylinder lock 3 is unlocked with a spare key to obtain a number search state, and a dial 11 is turned to search the unlocking number. Since the position where the dial 11 is stopped is the unlocking number, the cylinder lock 3 is restored to a normal state and the spare key is removed to obtain the door-opened state. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a locker lock, and more particularly, to a dial-type locker lock that allows a temporary opening and number search with a combined key.

  Conventionally, many locker locks using dial locks have been used. Since the dial lock does not require a joint key, it is suitable for a locker lock used by an unspecified person. However, since the unlocking number may be forgotten, the one that allows the administrator to unlock with the combined key is used. There are those that reset the unlocking number when unlocking with the combined key and those that change the unlocking number after searching for the unlocking number and unlocking with the unlocking number. Since the mechanism for resetting the unlocking number is complicated, there are many that use the unlocking number changing function originally provided in the dial lock. Several examples of conventional dial lock number search techniques are given below.

  The “dial lock device” disclosed in Patent Document 1 allows the unlock number to be searched from the outside with a proximity switch so as to be able to respond quickly to troubles caused by forgetting the unlock number. is there. As shown in FIG. 9A, the dial lock device has three dials. The outer peripheral edge of each dial protrudes from the front plate. The lock gear with which each dial meshes is provided with a sensitive body to which the proximity switch is sensitive at a predetermined angular position. The probe is provided with a proximity switch sensor. Operate the dial while the sensor is close to the dial. When the sensitive body comes to an angular position approaching the sensor unit, the proximity switch is sensitive to search for the unlock number.

  The “dial lock” disclosed in Patent Document 2 can be known by a gauge by an external operation even when the password of the dial is forgotten. As shown in FIG. 9B, a dial is mounted around the support shaft via an intermediate sleeve. When the dial matches the password, the advance / retreat shaft fits into the recess on the outer peripheral surface of the intermediate sleeve, and the rear end of the advance / retreat shaft is disengaged from the hole of the movable plate so that the movable plate can move. The operation knob can be rotated, and the movable plate moves with the rotation of the operation knob. The hook member engaged with the engagement member on the rocker body side is rotated by the operation knob, and the hook member can be detached from the engagement member on the rocker body side. If the dial does not match the password, the rear end of the advancing / retracting shaft engages with the hole of the movable plate to prevent the movable plate from moving. The rear end position of the advance / retreat axis can be detected by inserting a gauge into the hole. The dial number for unlocking can be known by the insertion depth of the gauge.

  The “dial lock device” disclosed in Patent Document 3 can be easily unlocked easily even if the unlocking number is forgotten, and the unlocking number can be visually confirmed. As shown in FIG.9 (c), a dial lock apparatus is attached to the door side. If the dial lock is an unlock number, the cam plate attached to the cylindrical body of the lock mechanism can slide. The cam plate is engaged with and disengaged from the receiving portion on the fixed side. The unlocking number that allows the cam plate to slide can be changed. Even when the dial lock is not the unlock number, when the cylindrical body of the lock mechanism is turned by a key operation, the cam plate rotates and comes off the receiving part on the fixed side. By providing a mark on the inner cylinder that can be viewed from the back side of the dial lock device with the inner cylinder in the unlocked position, and by aligning the visible mark at the unlocked position while turning the inner cylinder after emergency unlocking. , You can check the forgotten unlock number.

  The “code lock device” disclosed in Patent Document 4 can easily search for an unlock code using a master key without using a special search tool. As shown in FIG. 9D, the unlock code search mechanism searches for the unlock code for each dial. The unlocking code search mechanism includes a displacement mechanism and a search member. When the inner cylinder is rotated beyond the rotation angle range of the outer cylinder of the actuator, the displacement mechanism displaces the operating shaft exceeding the set amount. The search member for the unlock code is arranged at the position of each dial on the operating shaft. An engagement step is formed on the side surface of the lock gear facing the search member. The search member has a protrusion. When the operating shaft is displaced beyond the set amount, for the lock gear corresponding to the dial of the rotation angle where the unlocking code is not aligned, the protrusion is in a state that allows the lock gear to rotate. Abuts the side. For a lock gear corresponding to a dial having a rotation angle with the same unlock code, the protrusion engages with an engagement step to prevent the lock gear from rotating.

  The “composite lock assembly” disclosed in Patent Document 5 can be used to visually find an unlocking number and reset it to a different unlocking number when the user forgets the unlocking number. As shown in FIG. 9 (e), the composite lock assembly includes a housing, a dial portion, a key portion, and number detection means. The dial part, the key part, and the number detection means are arranged in the housing. The composite lock assembly is unlocked by a key and an unlock number. When the user forgets the unlock number, the unlock number can be found again by the number detecting means. The composite lock assembly can be unlocked again with the unlock number.

  However, the conventional number search method has the following problems. Since the dial lock is opened with a combination key and the like, a number is searched using means such as a sensor, or the number is searched visually, so the configuration becomes complicated and the number search operation becomes complicated.

  An object of the present invention is to solve the above-described conventional problems and to easily search for a dial lock number from the front side of the lock using a joint key.

  In order to solve the above-described problems, in the present invention, the locker lock is in any one of an unlocked state, a locked state, a temporary unlocked state, and a number search state, and a dial lock including a dial and a sleeve, A knob that can rotate the arm in the unlocked state, a bolt that stops the movement of the knob in the locked state of the dial lock, and a sleeve number for searching for the unlocked number of the dial lock in the dial lock number search state A search arm in contact with the search unit, and a cylinder lock that makes the dial lock temporarily unlocked by unlocking with the key and moves the bolt to the unlocked position and simultaneously brings the search arm into contact with the number search unit of the sleeve. It was set as the structure to comprise.

The number search unit 16 has a certain number. The sleeve 12 is adapted to rotate around the shaft 7. In the unlocked state of the dial lock 1 shown in FIG. 7B, the dial 11 and the sleeve 12 are separated, and the dial 11 rotates freely. The sleeve 12 does not rotate and remains engaged with the tip of the bolt 5. When the knob 2 is turned to the LOCK side in the unlocked state, the dial 11 and the sleeve 12 are coupled. When the dial 11 is turned in this state, the sleeve 12 rotates and deviates from the unlocking number, and the locked state shown in FIG.

  When the cylinder lock 3 is unlocked in the locked state, it is pushed by the temporary opening arm 17 connected to the cylinder lock 3, so that the end of the bolt 5 is forcibly moved to the temporary opening position, and FIG. The number search state shown in FIG. At this time, the number search arm 6 hits the number search unit 16 of the sleeve 12. Since the dial 11 and the sleeve 12 remain connected, the sleeve 12 also rotates when the dial 11 is turned. When the position of the unlocking number is reached, the tip of the number search arm 6 fits into the recess of the number search portion 16 of the sleeve 12, and the sleeve 12 cannot move. When the unlocked number is reached, the cylinder lock 3 is returned to the normal state, and the knob 2 is turned to the OPEN position to enter the unlocked state.

  Next, the state transition of the locker lock will be described with reference to FIG. When the dial lock is in the unlocked state and the knob is in the OPEN position, the locker lock is in the open state. At this time, the dial is separated from the sleeve. The bolt is in the open position and the knob can rotate. When the door is open, close the door, set the unlock number, and turn the knob to the LOCK side. When the door is closed, the dial is joined to the sleeve. When the dial is turned and shifted from the unlocked number, the dial lock is locked, and the locker lock is locked so that the door does not open even when the knob is turned. When the number of the dial lock is changed to the unlocked number in the locked state, the door is returned to the closed state. When the knob is turned to the OPEN side with the door closed, the door opens and returns to the door open state.

  In the locked state, when the cylinder lock is unlocked with the combined key to the unlocked state, the bolt is forcibly moved to the temporary open position, and the knob turns in the OPEN direction so that the door can be opened. become. At this time, since the bolt is in the temporarily open position, the knob can only turn up to 75 degrees in the OPEN direction, and the dial remains connected to the sleeve. At the same time, the tip of the search arm contacts the sleeve. In this state, turn the dial to search for numbers. The place where the unlocking number is stopped when the dial is turned. The search is complete when all dials are unlocked. When the number search is completed and the cylinder lock is returned to the normal state, the end of the bolt that has been moved to the temporary open position by the temporary open arm of the cylinder lock returns to the open position off the convex portion of the knob 2. . When the knob is turned to the OPEN position, the locker lock is opened. Since the dial is separated from the sleeve, the unlocking number can be changed. The number search can be executed even in a temporarily closed state.

  In this example, the free-number type dial lock has been described, but a fixed-number type dial lock can be similarly applied. In a fixed number type dial lock, a number search state is set with a joint key, a dial is rotated to search for a number, a dial lock is set to an unlocked state, a number change state is changed, and an unlocked number is changed. In the fixed number type dial lock, the dial and the sleeve are always connected. Only when the number change button is pushed to change the number, the dial and the sleeve are separated, and the unlocking number can be changed.

  As described above, in the embodiment of the present invention, the locker lock is temporarily opened by unlocking the cylinder lock with the combined key, and the number search state is set. Since the configuration is such that the dial is unlocked, the dial lock number search can be easily performed.

  The locker lock of the present invention is most suitable as a lock for a shared use locker. If the combined key is a TSA key, it can also be applied as a TSA lock for travel bags.
