When the lock group 17 is locked, the rotor 172 of the lock group 17 is rotated in a predetermined locking direction, and the lock plate 171 is advanced toward the receiving portion 123 on the casing 12 side via the guide hole 144. The lock plate 171 is engaged with the engaging portion 31 (engagement surface 312) at one end of the actuating lever 30 in the indicator assembly portion 145, and the end portion is pushed upward to swing the actuating lever 30, and the engaging portion 31 is engaged. The convex portion 311 is engaged with the receiving portion 123 of the casing 12. Thereby, the lock lever 171 of the lock group 17 is fixed to the receiving portion 123 of the casing 12 via the engaging portion 31 (the convex portion 311) of the actuating lever 30. At the same time, the lock state display portion 321 of the display member 32 at the other end of the actuating lever 30 faces the display window 146 to display the locked state of the lock group 17.

When the door panel 6 is opened to the fixed frame, as shown in Fig. 10 (2), the keyhole insertion key of the lock group 17 is rotated in a predetermined non-locking direction to rotate the rotor 172 in a predetermined non-locking direction, and locked. The plate 171 is retracted toward the lock group housing portion 142 via the upper and lower guide holes 144. Thereby, the engagement of the lock plate 171 with the actuating lever 30 is released. Due to the rotational bias of the spring means 33, the actuating lever 30 is swung away from the receiving portion 123 side of the casing 12, and the convex portion 311 is disengaged from the receiving portion 123. At the same time, at the other end of the actuating lever 30, the non-locking state display portion 322 of the display member 32 faces the display window 146 to display the unlocked state of the lock group 17. Further, when the front lower portion of the push button stopper 15 is pressed, as shown in Fig. 10 (3), the stopper 15 is rotationally displaced downward, and the locking portion 149 and the stopper 15 at the lower end of the handle 14 are released. The engagement of the upper end portion 151 causes the handle 14 to be pivoted from the inside of the casing 12 to a predetermined standing position by the rotation of the spring means 2 on the rotating shaft 13. At this time, the knob 14 is rotated by the bobbin spring 22 on the rotating shaft 13 to rotate the knob 14. With the rotation of the rotating shaft 13, the bobbin adjusting spring 21 on the rotating shaft 13 is wound in the direction of tightening the rotating shaft 13, and the adjusting rotary shaft 13 is reduced by the action of the viscous liquid 24. At the rotational speed, the handle 14 can be rotated at a suitable speed at a low speed and slowly ejected to a predetermined protruding position. Further, by rotating the handle 14 in the predetermined opening direction in the predetermined protruding position, the hook 16 is integrally rotated in the rotation direction of the handle 14, and the engagement with the carrier on the fixed frame side is released, and the door is closed. The board is unlocked.

When the door panel is closed from this state, the operation mode is opposite to the above. That is, the handle 14 is first rotated in the predetermined closing direction. Thereby, the hook 16 and the handle 14 are integrally rotated in the same direction, and are engaged with the tab on the side of the fixed frame. The handle 14 is then pushed back into the casing 12. At this time, the bobbin adjusting spring 21 is wound around the rotating shaft 13 of the handle 14 in the direction of the screwing shaft, but the rotation of the rotating shaft 13 in the reverse direction as the handle 14 is pushed back is raised. The adjusting wire spring 21 is wound back in the tightening direction of the loosening rotating shaft 13, whereby the load of the adjusting wire spring 21 on the rotating shaft 13 is lost, and the action of pushing the handle 14 back into the casing 12 is performed. There will be no impact. Therefore, the handle 14 can be maintained in good operability by pushing the handle 14 back into the casing 12 in the past in response to the rotational elastic pressure of the wire lifting cymbal 22. By pushing back the handle 14, the rotating side end portion of the handle 14, that is, the guiding surface 150 at the lower end of the handle 14, abuts against the upper end portion 51 of the stopper 15 to rotate the stopper 15 downward. When the lower end of the handle 14 straddles the upper end portion 151 of the stopper 15, the stopper 15 is elastically returned to the original position, and the locking portion 149 at the lower end of the handle 14 is engaged with the upper end portion 151 of the stopper 15. The lock group accommodating portion 142 and the indicator assembly portion 145 provided on the back surface of the handle 14 are fitted into the cylindrical recess portion 122 in the casing 12, and the handle 14 is held in the casing 12, and the door panel is again in a locked state. Then, the key is inserted into the key hole of the lock group 17, and the rotation operation is performed in the predetermined locking direction. Thereby, the rotor 172 of the lock group 17 is rotated in the predetermined locking direction, and the lock plate 171 advances toward the receiving portion 123 on the casing 12 side through the upper and lower guide holes 144. When the locking plate 171 is engaged with the engaging portion 31 (the engaging surface 312) at one end of the actuating lever 30, the operating lever 30 is rocked, and the convex portion 311 of the engaging portion 31 is engaged with the engaging portion 31. The receiving portion 123 on the side of the casing 12. Thereby, the lock plate 171 of the lock group 17 is fixed to the receiving portion 123 on the casing 12 side via the engaging portion 31 (the convex portion 311) of the actuating lever 30. At the same time, at the other end of the actuating lever 30, the lock state display portion 321 of the display member 32 faces the display window 146, and the lock state of the lock group 17 is displayed on the display window 146.

As described above, the handle device 1 is in the form of releasing the engagement of the handle 14 with the stopper 15 by the pressing operation of the stopper 15, and the handle 14 is lifted from the casing 12 by the rotation of the spring means 2 to In the form of a predetermined standing position, the spring means 2 has a spring lift adjustment spring 21 that tightens the direction of the rotary shaft 13 in the direction of the rotation of the handle 14, and returns to the handle 14 by the lifted handle. a direction of rotation of the rotating shaft 13 is wound around the rotating shaft 13; and an elastic spring 22 is wound from the elastic lifting spring to rotate the rotating shaft 13 in the direction of the lifting handle 14; These poppet adjustment springs 21 interact with the poppet springs 22 to adjust the lift speed of the handle 14. Therefore, while the operation button type stopper 15 is pressed, the handle 14 can be rotated at an appropriate speed at a low speed, and slowly raised to a predetermined protruding position. Therefore, the handle 14 does not rise sharply, and the door panel does not make a slamming sound, but can be lifted at a suitable speed. On the other hand, when the handle 14 is pushed back into the casing 12, the spring 21 for the lift adjustment is rolled back toward the tightening direction of the loosening shaft 13 as the rotation shaft is rotated when the handle 14 is pushed back. Therefore, there is no influence on the action of pushing back the handle 12 into the casing 12. Therefore, the handle 14 can be pushed back into the casing 12 as in the past by the rotational elastic pressure of the wire spring 22 which resists the use of the elastic lift, and the handle 14 can be maintained in good operability.

Further, in the case of the spring means 2, the lift adjustment spring 21 is inserted into the sleeve 23, and the viscous liquid 24 is injected into the lift adjustment spring, and the lift spring 23 is wound around the outer side of the sleeve 23. In this way, it is possible to surely prevent the viscous liquid 24 from leaking out of the spring means 2.

Furthermore, in this embodiment, the spring means 2 is configured as a double structure of the lift-up adjustment spring 21 and the pop-up spring 22 to adjust the lift speed of the handle 14, but it may be replaced by the spring means 2 or with the spring means 2. The absorber is disposed between the casing and the handle to adjust the lifting speed of the handle. At this time, as shown in FIG. 11, when the end of the handle 14 of the rotating shaft 13 is lifted up, the position of the casing 12 will be abutted or approached, and the main body of the flushing absorber 7 is provided to make the piston of the flushing absorber 7. The rod 71 protrudes toward the end of the handle 14 of the rotating shaft 13, and can be engaged with the end of the handle 14 when the handle 14 is lifted up, whereby the lifting speed of the handle 12 can be adjusted by the action of the suction absorber 7.

Further, in the handle device 1, the handle portion 14 is provided with an instruction portion 3 that is coupled to the lock group 17 and interlocked with the rotation operation of the key 18 to switch the lock state when the handle 14 is locked by the lock group 17. , and the unlocked state of unlocking.
