It extends in a substantially horizontal direction from the bottom surface, and is attached by being urged to rotate in the vertical direction, ie, toward the cylinder lock 7 (the outer peripheral surface thereof).

  The handle device H has such a configuration, and by attaching the lock part 8 to the optional part space S (locking position P), the handle lever 4 housed in the handle base 1 is connected to the dial lock 6 and the cylinder lock 7. The lock is doubled and the handle lever 4 is unlocked by unlocking both the dial lock 6 and the cylinder lock 7 (hereinafter referred to as “double lock type”). By attaching the lock lever 9 to the (locking position P), the handle base 1 and the handle lever 4 are locked by the dial lock 6 and the cylinder lock 7, and either the dial lock 6 or the cylinder lock 7 is unlocked. By doing so, the handle lever 4 is unlocked (hereinafter referred to as “emergency unlocking type”). In any case, as described above, the handle base 1 is fitted into the vertically long receiving hole of the door from the front side of the door and is fitted from the back side of the handle base 1 with a washer plate and a screw having a U-shaped cross section. It is fastened to the door and fixed to the door.

FIG. 4 shows an example of use when the handle device H is configured in a double lock type.
In this handle device H, the unlocking code string of the dial lock 6 is assigned in advance by the owner or administrator of the device to the user who is permitted to use the device, and the cylinder lock 7 is unlocked. A key 74 is handed over.
When the user closes and locks the door to use the device, the door is closed and the handle lever 4 is laid down on the handle base 1 as shown in FIG. Each dial disk 61 of the dial lock 6 is turned to an array other than the assigned specific unlock code string. As a result, the lock plate 65 of the dial lock 4 rotates, and the locking end portion of the lock plate 65 comes to a position where the stop portion of the slider 66 abuts, so that the backward movement of the slider 66 is prevented by the lock plate 65. The lock 6 is locked. Even if the handle lever 4 is to be raised from the handle base 1 in the locked state, the latch 67 in the forward state of the dial lock 6 is engaged with the latch engaging portion 83 of the lock part 8 and the movement to the latch guide portion 82 is restricted. Thus, the handle lever 4 is prevented from rotating in the pulling direction. Further, when the user further inserts the key 74 into the key hole of the cylinder lock 7 and rotates it in the locking direction, the lock member 73 moves forward by the rotation of the rotor 71 of the cylinder lock 7 (upward in FIG. 4A). And is engaged with the lock member engaging portion (lock groove) 84 of the lock part 8. As a result, even if the handle lever 4 is raised from the handle base 1 around the pivot axis and is about to rotate, the lock member 73 in the forward movement state of the cylinder lock 7 is engaged with the lock member engaging portion (lock groove) 84 of the lock part 8. The rotation in the raising direction of the handle lever 4 is stopped and the handle lever 4 is double-locked (double lock).
On the other hand, when the user unlocks and opens the door in order to use the device, the key 74 is inserted into the key hole of the cylinder lock 7 from the aforementioned locked state of the door, and is rotated in the unlocking direction. As a result, the rotor 71 of the cylinder lock 7 rotates and the lock member 73 moves backward (moves downward in FIG. 4 (1)) and engages with the lock member engaging portion (lock groove) 84 of the lock part 8. Is released. Here, the lock of the cylinder lock 7 is first released, but the dial lock 6 is in the locked state, that is, the latch 67 at the tip of the slider 66 is engaged with the latch engaging portion 81 of the lock part 8. Since the movement of the slider 66 in the backward direction is blocked by the lock plate 65, the handle lever 4 is controlled to be unable to rotate in the raising direction, and the raising operation of the handle lever cannot be performed. Subsequently, each dial disk 61 of the dial lock 6 is turned to an assigned specific unlock code string arrangement. As a result, the lock plate 65 of the dial lock 6 rotates and returns to the original position, and the lock end portion of the lock plate 65 is returned to a position where it does not engage with the stop portion of the slider 66. Thus, the backward movement of the slider 66 in the direction is not prevented, and the dial lock 6 is unlocked. Here, the lock of the dial lock 6 is released. In this unlocked state, when the handle lever 4 is raised from the handle base 1 and rotated in the direction, the latch 67 of the dial lock 6 is moved backward and forward by the guide of the latch guide portion 82 from the latch engaging portion 83 of the lock part 8. As shown in FIG. 4 (2), the lever moves over the latch guide portion 82 and is detached from the lock part 8, causing the handle lever 4 to be tilted at a predetermined angle. When the handle lever 4 is rotated around the handle shaft 2, the stopper 5 connected to the handle lever 4 via the handle shaft 2 is detached from the receiving portion on the fixed frame body side such as the device storage box body. The restraint of the door on the fixed frame is released, and the door is opened by pulling the handle lever 4 forward.
Thus, in the double-lock type handle device H, the handle lever 4 is double-locked (double-locked) by the dial lock 6 and the cylinder lock 7 in a state where the handle lever 4 is housed on the handle base 1. It is possible to unlock the handle lever 4 only after unlocking both the cylinder lock 7 and the cylinder lock 7.

An example of use when the handle device H is configured in an emergency unlocking format will be described with reference to FIG.
In this handle device H, the unlocking code string of the dial lock 6 is assigned in advance by the owner or administrator to the user who is permitted to use the device by the owner or administrator of the device. In addition, the cylinder lock 7 is normally locked, and for example, an administrator who has wider authority than a general user (hereinafter referred to as an advanced authority) raises the handle lever 4 without using an individual unlock code string. The key 74 of the cylinder lock 7 is given to the senior authority so that it can be operated.
When the user closes and locks the door of the device, the user closes the door and turns each dial disk 61 of the dial lock 6 to an arrangement other than the assigned specific unlock code string. As a result, the lock plate 65 is rotated, the lock end portion of the lock plate 65 is moved to a position where the stop portion of the slider 66 abuts, and the backward movement of the slider 66 is prevented by the lock plate 65. The lock lever 9 engaged with the latch 67 at the tip of 66 cannot be retracted and rotated in the restraint releasing direction (upward in FIG. 3). When the handle lever 4 is raised from the handle base 1 and rotated in the direction caused by the locked state of the dial lock 6, the handle lever 4 is rotated by a slight angle, and the tip of the lock member 73 of the cylinder lock 7 is moved to the lock lever 9. Rotation in the direction is prevented when it is pressed against the cam inclined surface 94.
Even in such a locked state of the dial lock 6, only a high-ranking authority can raise the handle lever 4 and rotate it in the direction without using an individual unlock code string. As described above, since the senior authority is given the key 74 of the cylinder lock 7, if the user forgets the unlock code string of the dial lock 6, or the part who does not know the unlock code string of the dial lock 6. In an emergency such as when the dial disc 61 is turned to an irregular angle by an outsider or an intruder and the dial lock 6 is unintentionally set to the locked state, the senior authority uses the key 74 to hold the cylinder lock 7 It is unlocked, the handle lever 4 can be operated, the door can be opened, and the locked state of the dial lock 6 can be reset. In this case, the senior authority inserts the key 74 into the key hole of the rotor 71 of the cylinder lock 7 and drives the internal lock mechanism in the release direction by the required key pile code. When the rotatable rotor 71 is rotated by the key 74 in the unlocking direction, the lock member 73 is pulled into the handle lever 4 from the insertion opening 45 of the handle lever 4, and the distal end portion of the lock member 73 and the lock lever 9 is disengaged from the lock groove 93. As described above, when the dial lock 6 is in the locked state, the locking plate 65 is in a position where the locking end of the slider 66 abuts against the locking end of the slider 66, so that the backward movement of the slider 66 is blocked by the lock plate 65. The lever 9 cannot be retracted and rotated in the restraint releasing direction (upward in FIG. 3), but when the cylinder lock 7 is unlocked with the key 74, the lock member 73 retracts to a position where it does not engage with the lock lever 9. Therefore, the handle lever 4 is not interfered by the lock lever 9, and the handle lever 4 can be pulled out from the front opening 10 of the handle base 1. That is, the lock of the handle lever 4 can be unlocked by simply unlocking the cylinder lock 7 with the key 74 without aligning the dial disks 61 of the dial lock 6 with the unlock code string. When resetting the locked state of the dial lock 6, after opening the door, an appropriate resetting means is operated from the back side of the door to release the unauthorized locked state and perform a recovery process.
On the other hand, when the user unlocks and opens the door to use the device, the sign of the outer peripheral surface of the plurality of dial disks 61 is properly corrected so as to be the unlock code string assigned to him / her. Reverse rotation.
When the codes of the dial disks 4 are arranged in the assigned unlock code string, the dial lock 6 is unlocked. That is, the lock end portion of the lock plate 5 is moved to a position where it does not engage with the stop portion of the slider 66, and the slider 66 is not prevented from retreating toward the main portion of the dial lock 6. At this time, the cylinder lock 6 is in the locked state, and the distal end portion of the lock member 73 is engaged with the lock groove 93 of the lock lever 9, and this engagement state is rotated toward the cylinder lock 7 by the spring member of the lock lever 9. The handle lever 4 is restrained by the fall and storage position in the front opening 10 of the handle base 1.
In this state, when the handle lever 4 is raised from the handle base 1 and rotated in the direction, the distal end portion of the lock member 73 pushes the cam inclined surface 94 continuous from the lock groove 93 of the lock lever 9, so that the lock lever 9 pivots. The lock lever 9 retreats and rotates in the constraint release direction (upward in FIG. 3) as the center, and the lock lever 9 pushes (pushes up) the latch 67 at the tip of the slider 66 to move the latch 67 backward. When the handle lever 4 is pulled out from the handle base 1 to a certain angle, the lock lever 73 is not pressed against the lock lever 9 by the distal end portion of the lock member 73. Return to. The slider 66 also moves forward and returns to the original position by the bias of the spring member 22.
When the handle lever 4 is rotated during or after the handle lever 4 is gripped by the hand and rotated around the handle shaft 2, the stopper 5 connected to the handle lever 4 via the handle shaft 2 is stored in the device. The door is released from the receiving part on the fixed frame body side such as the box body, and the restraint of the door on the fixed frame body is released, and the door is opened by pulling the handle lever 4 forward.
Thus, in the emergency unlocking type handle device H, the handle lever 4 is locked by the dial lock 6 and the cylinder lock 7 with the handle lever 4 being housed on the handle base 1. If the unlock code string is aligned, the handle lever 4 is unlocked and the handle lever 4 can be operated, and the cylinder lock 7 can be used for locking and unlocking in case of emergency such as forgetting the code. Moreover, it is possible to use only one of the dial lock 6 or the cylinder lock 7 as a single lock.

  As described above, according to this handle device H, when the door is opened and closed, the handle lever 4 is raised from the handle base 1 and rotated to disengage the stopper plate 5 from the fixed frame side receiver, In a handle device in which the handle lever 4 is stored on the handle base 1 after the door is closed, a dial lock 6 and a cylinder lock 7 are provided on the handle lever 4, and the handle base 1 and the handle lever 4 are disposed. The lock position P of the latch 67 of the dial lock 6 and the lock member 73 of the cylinder lock 7 is taken between the dial lock 6 and the cylinder lock 7, and the lock part 8 is handled at this lock position P. The handle lever 4 housed in the handle base 1 is double-locked with the dial lock 6 and the cylinder lock 7 by being fixed to the base 1 side. Since the dial lock 6 and the cylinder lock 7 are both unlocked, the handle lever 4 is unlocked so that the dial lock 6 and the cylinder lock 7 have a simple shape and structure. A handle device having a reliable double lock function can be realized relatively easily only by using. In this manner, the dial lock 6 and the cylinder lock 7 are associated with each other and incorporated in the handle lever 4, so that a great number of key differences can be easily obtained even if the entire apparatus is thin. For the purpose of strengthening, it is possible to respond to a request for providing a lock system with a double lock function (unable to unlock an object without operating two different keys simultaneously).

  Further, according to this handle device H, when the door is opened and closed, the handle lever 4 is raised from the handle base 1 and rotated to engage and disengage the clasp 5 with respect to the catch on the fixed frame side, thereby closing the door. After that, in the handle device of the type in which the handle lever 4 is laid down and stored on the handle base 1, a dial lock 6 and a cylinder lock 7 are arranged on the handle lever 4, and between the handle base 1 and the handle lever 4. In addition, the lock position P of the latch 67 of the dial lock 6 and the lock member 73 of the cylinder lock 7 is taken between the dial lock 6 and the cylinder lock 7, and an optional lock part 8 is attached to the handle base at this lock position P. The handle lever 4 housed in the handle base 1 is double-locked by the dial lock 6 and the cylinder lock 7 by being fixed to the 1 side.
