[Problem that plan is trying to solve]

Accordingly, it is an object of the present invention to provide a lock handle device for a pull-out rotation type door which can reliably support the handle immersed in the front concave portion even against vibration or shock.

[Means for solving the problem]

Hereinafter, referring to the reference numerals in the accompanying drawings, in the pull-out door lock handle device of the present invention, the casing (2) is fixed to the door (1); and the shaft portion (3) of the proximal end of the casing (2) And a locking shaft (5) rotatably inserted in the axial direction, and fixed to the rear end of the fixed iron plate (4); A handle (8) whose proximal end is conically joined to the front end of the visibility shaft (5) by a transverse pivot shaft (7); and is provided between the visibility shaft (5) and the handle (8), and the pivot shaft (7). Is connected to the driving spring (9) for pressing the handle (8) in the protruding direction with a transverse pivot shaft (10) at the distal end of the handle (8), and the transverse pivot shaft (10) on the rear side thereof. The pusher which protruded the leg part 12 of the minimum length required on the horizontal line which passed, and provided the lock hole 13 and the locking click part 14 in the front-end | tip of the leg part 12. (11); and a posture maintenance spring (15), which is provided between the handle (8) and the push button (11), and the push button (11) is aligned on an extension of the handle (8); The latch body 20 is fixed to the lock receiving portion 16 at the distal end portion, and the latch body 20 moves forward and backward in the lock hole 13 in response to the rotation of the rotor 19 by the key 18. The lock unit 17 which presses the sieve 20 forward by the return spring 21 in the direction of the leg part 12, and the locking click part 14 of the push button 11 is located in a forward position. The length of the latch body 20 is set so that it latches completely to the latch body 20, and only the front-end | tip part of the latch body 20 is caught with respect to the latch body 20 in a retracted position.

(Action)

As shown in FIG. 6, when the rotor 19 of the lock unit 17 is in the locked position, the latch body 20 is in the most advanced position, and the front end of the latch body 20 is push button 11. Is engaged with the lock hole 13 of the leg part 12 of FIG. Therefore, the handle 8 is held at the position immersed in the front recess 6 of the casing 2, and the fixed steel plate 4 fixed to the visibility shaft 5 has a receiving portion on the side of the fixed frame body 22. The door 1 is locked with respect to the fixed frame body 22 in the engaged position with (23).

In this apparatus, the operation for rotating the handle 8 from the casing 2 is performed by a two-step operation. In the operation in the first step, as shown in FIG. 4, when the key 18 is inserted into the lock unit 17 and the rotor 19 is turned in the unlocking direction, the latch body 20 interlocks with the rotor 19. The retraction slides against the pressure of the return spring 21, and the tip of the latch body 20 escapes from the stop hole 13. In this step, since the distal end of the latch body 20 is engaged with the engaging click portion 14 of the distal end of the push button 11, the handle 8 is still immersed in the front recess 6 of the casing 20. It is kept in position.

In the operation of the second step, as shown in FIG. 5, the operator presses the front portion 11a of the push button 11 with the fingertip to push the push button 11 against the pressing of the posture maintenance spring 15. ) Is rotated about the transverse pivot shaft 10, the leg 12 is moved to the proximal end, so that the engagement between the locking click portion 14 and the distal end of the latch body 20 is released and the electrostatic unit 17 The restraint of the handle 8 by () is released.

When the finger tip is moved from the front portion 11a of the push button 11 to the front portion 17a of the electrostatic unit 17 and the pressure of the push button 11 is released, the handle 8 and the visibility shaft 5 Since the rotational pressing force of the driving spring 9 equipped between) is stronger than the bearing force of the posture holding spring 15 provided between the handle 8 and the push button 11, the handle 8 is instantaneously crossed. It rapidly rotates about the pivot shaft 7 and protrudes from the front recess 6 of the casing 2 as shown in FIG.

When the handle 8 protrudes, the push button 11 is reversely rotated by the holding force of the posture holding spring 15, and is returned to the position aligned with the extension of the handle 8.

Holding the protruding handle 8 and turning it in a predetermined direction, the visibility shaft 5 connected to the handle 8 on the transverse pivot shaft 7 is supported by the shaft portion and rotates integrally, so that the stationary steel plate 4 is fixed. It separates from the receiving part 23 of the sieve 22. As shown in FIG. Therefore, the door 1 which canceled the locking with respect to the fixing frame 22 is opened by putting the handle 8 forward.

When pushed into the recessed part 6, the locking click part 14 of the push button 11 pushes the front-end inclined surface 20a of the latch body 20. As shown in FIG. By this pressurization, the latch body 20 once slides backward against the pressurization of the return spring 21.

When the push-up of the handle 8 progresses and the locking click portion 14 crosses the rear side of the distal end portion of the latch body 20, the latch body 20 is immediately pressed by the return spring 21. The whole body is slid, and the engaging click portion 14 and the distal end of the latch body 20 are engaged. At this time, since the locking click portion 14 is located on the horizontal line passing through the transverse pivot shaft 10, the locking click generated by the driving spring 9 provided between the handle 8 and the visibility shaft 5 is clicked. The direction of reaction applied to the portion 14 moves in the horizontal direction passing through the transverse pivot axis 10. Therefore, the rotational force of the push button 11 by the spring reaction force does not arise, and the handle 8 is locked to the immersion position in the front recessed part 6 of the casing 2 correctly.
