It is possible to rotate forward and backward around the axis.

  The drive engagement portion 29 is arranged to engage the contact surface 44 of the passive engagement portion 28 of the dead bolt 21 to move the dead bolt 21 to the unlocked position when the rotor cam 22 rotates to the unlocked position. To be done.

  As shown in FIGS. 1 and 3, the lock unit 8 is incorporated in the handle 5 with a guard hood 50 interposed between a lock case 48 and a fixing ring 49. The lock case 48 is cylindrical and has a threaded portion 51 on the outer periphery, and has a pair of flat surfaces 52 parallel to the axis on the opposite side surfaces. The fixing ring 49 has an annular groove 53 on the outer circumference and is screwed and fixed to the outer circumference of the lock case 48. The guard hood 50 is made of a hard material and effectively resists violent destruction by a drill or the like.

  As shown in FIGS. 1 and 3, the lock unit 8 is fixed in the handle shaft portion 17 by a fixing member 35 which is inserted into the handle shaft portion 17 through the fixing metal fitting insertion opening 34 in a direction orthogonal to the axis line.

  As shown in FIGS. 2 and 3, a push solenoid 55 electrically connected to the control center is fixed to the rear surface side of the lower collar portion 10 of the handle case 2 via a mounting bracket 56. The push solenoid 55 is for pushing the dead bolt 21 in the locked position to the unlocked position in response to an electric signal from the control center, and is provided on the protrusion 39 of the dead bolt 21 projecting downward from the slit 40 to the bearing tubular portion 9. The push bar 57 is fixed with its tip facing each other.

  A cover metal fitting 58 made of a hard material is attached to the lower rear portion of the handle case 2 to make it difficult to violently approach the lower end portion of the push bar 57 of the push solenoid 55 from the front. As a result, it is prevented that the front panel of the door D is perforated and the push bar 57 is pushed up from the lower end side by a tool to unlock the door illegally.

  A micro switch 59 that detects the position of the handle 5 and sends an electric signal to the control center is attached to the rear surface side of the upper collar portion 10 of the handle case. The base end side of the sensor pin 60 penetrating the flange portion 10 so as to be movable in the front-rear direction abuts the actuator of the micro switch 59, and the tip end thereof projects from the front surface of the handle receiving recess 11.

  Now, the door D is unlocked from the state shown in FIGS. 3 and 8 in which the door D is locked by the locking member 4 in the closed state, the door D is opened, and after the work is completed, the door D is closed again. I will explain the process of locking.

  In the state shown in FIGS. 3 and 8, the lock member 4 is in the locked position, the handle 5 is retracted into the handle case 2, and the dead bolt 21 is in the locked position in which the dead bolt 21 is engaged with the through opening 37 of the inner cylinder 3, The rotor 26 and the rotor cam 22 of the lock unit 8 are all in the lock position.

  From this state, when the key is inserted into the lock and rotated clockwise by about 90 ° in FIG. 8, the drive engagement portion 29 of the rotor cam 22 pushes the contact surface 44 of the passive engagement portion of the dead bolt 21, and Pull the bolt 21 to the unlocked position. At the same time when the dead bolt 21 comes out of the through opening 37 of the inner cylinder 3, the handle 5 is pushed out of the handle case 2 by the spring member 6, and the dead bolt 21 is held in the unlocked position by the peripheral wall 36 of the inner cylinder 3. The state shown in FIG. 9 is obtained.

As a result, when the handle 5 is gripped and rotated, for example, by 90 ° in the counterclockwise direction, the locking member 4 rotates together with the inner cylinder 3 to the unlocked position, and the corresponding engaging portion of the casing (not shown) Since it comes off, the door D can be opened.
When the required work is completed and the door D is closed, the handle 5 together with the inner cylinder 3 and the locking member 4 is rotated 90 ° clockwise to the locked position, and the handle 5 is pushed into the handle case 2. The dead bolt 21 is pushed by the spring 27 and automatically protrudes from the handle shaft portion 17 to engage with the through opening 37 at a position where the through opening 37 of No. 3 and the slit 40 of the handle case 2 face each other. Locked in the case.

  Further, as shown in FIG. 10, it is possible to perform an unlocking operation by exciting the solenoid 55 as shown in FIG. 10 by a remote operation from the control center without operating the lock. When the solenoid 55 is excited, the push bar 57 projects upward and pushes up the dead bolt 21 to the unlocked position, and the handle 5 is pushed out of the handle case 2. Therefore, the lock operation is unnecessary. This also allows remote emergency unlocking. By adding an electrical authentication device as necessary and restricting the unlocking authority, the unlocking means can be diversified while improving the security, and the application of the pop-out type lock handle device can be greatly expanded. .
