Description

  The present invention relates to a locking device.

As a locking device using an electric lock, the one described in Patent Document 1 is known. In this conventional example, the lock device has an outer lock portion (electric lock) having a touch switch (locking / unlocking control button) and an outer door handle (handle body) for operating the latch bolt, and the door opening operation. First, after operating the lock control button of the electric lock, the handle body is operated.
JP 2003-343129 A

  However, in the above-described conventional example, the door opening operation has a problem that the operability is poor because it is necessary to operate the handle main body after once touching a portion different from the handle main body.

  The present invention has been made to eliminate the above-described drawbacks, and an object of the present invention is to provide a locking device with good operability. Another object of the present invention is to provide a handle device that can be used in the locking device.

  The lock device includes an electric lock 2 having a dead bolt 1 driven by an actuator, and a handle body 5 for operating a latch bolt 4 for maintaining the closed state of the door body 3. By disposing the lock / unlock control button 6 of the electric lock 2 on the handle body 5, the door opening operation is completed only by operating the handle body 5, thereby improving operability.

  The locking / unlocking control button 6 is appropriately determined in accordance with the configuration of the authentication unit for driving the electric lock 2, and when the authentication unit is configured to authenticate the code such as the input password, the numeric keypad or the like And is configured as a signal output switch for requesting the portable device to transmit an authentication code when it is configured to authenticate the authentication code transmitted by the portable device possessed by the user.

  The handle body 5 can be configured to perform a rotation operation on a plane parallel to the surface of the door body 3 when opening and closing, that is, when the latch bolt 4 is unlocked, but when configured as a push-pull handle Since the opening operation of the door body 3 is completed only by pushing into the handle main body 5 without performing a special latch bolt 4 releasing operation or pulling operation, the operability is further improved.

  In this case, if the locking / unlocking control button 6 is disposed in the vicinity of the rotation center of the handle body 5, the distance (arm length) between the locking / unlocking control button 6 and the handle body 5 is reduced. For this reason, when the locking / unlocking control button 6 is pressed, the rotational moment generated in the handle body 5 becomes as small as possible, and the rotation of the handle body 5 due to the pressing operation of the locking / unlocking control button 6 does not occur.

  If the back pressure applied to the deadbolt 1 during the operation of the electric lock 2 exceeds the driving force of the actuator, there is a possibility that the deadbolt 1 cannot be operated, but the handle body 5 rotates by pressing the locking / unlocking control button 6. In the present invention that does not, even if it is adopted in a push-type handle device, excessive back pressure applied to the dead bolt 1 is prevented by first hitting the dead bolt 1 in a locked state with the door frame. The latch bolt 4 is not inadvertently unlocked. As a result, operational reliability can be improved.

The handle device
A handle body 5 is rotatably connected to a handle base 7 fixed to the door body 3;
In the vicinity of the rotation center of the handle body 5, a lock / unlock control button 6 of the electric lock 2 that locks and unlocks the door body 3 by an actuator can be arranged.

  The handle body 5 that is gripped and rotated to open and close the door body 3 is usually located at a position away from the rotation center position in order to increase the arm length and effectively convert the operation force into the rotation force. Designed and used to be a key point. By disposing the locking / unlocking control button 6 in the vicinity of the rotary shaft, which is the opposite end of the above-mentioned force point, an inadvertent operation of the locking / unlocking control button 6 during the operation of the handle body 5 is surely prevented.

  As a result, it is possible to determine the operation of the electric lock 2 without considering the competition between the action of pressing the locking / unlocking control button 6 and the operation on the door body 3.

  According to the present invention, since the locking / unlocking operation can be performed by operating the handle body, the operability can be improved.
