[0011]

When the stopper plate 36 fixed to the rear end portion of the locking shaft 11 engages with the receiving portion 57 on the fixed frame body 56 side, and the handle 18 is retracted into the front concave portion 3 of the casing 1. As shown in FIG. 6, in the case of the push-type button unit, the push button 30 is rotationally biased by the attitude holding spring 39 in the direction in which the tip portion projects from the cutout portion 27 of the button case 24. , Locking claw portion 31 and locking protrusion 2
5, the push button 30 is aligned with the extension of the handle 18. The locking claw portion 20 at the tip end portion of the handle 18 engages with the rear surface 32 of the push button 30 on the base end portion side so that the handle 1
8 is held in the immersed position.

When in the same state as described above, as shown in FIG. 11, in the case of the slide type button unit, the button 6
5 is urged forward by a return spring 73. At this time, the side surface 69 of the button 65 is pressed against the stopper 72, and the forward biasing by the return spring 73 is suppressed, and the button 65 is held at this position. The locking claw portion 20 at the tip of the handle 18 engages with the locking projection 68 on the base end side of the button 65 to hold the handle 18 in the retracted position.

The lock plate 45 is at the maximum forward position, engages with the locking projection 26 of the button case 24 to lock the handle 18 at the retracted position, and the door 55 is fixed to the fixed frame 56. It is locked properly.

When the handle 18 is to be projected, the handle 18 shown in FIG.
As shown in, the key 4 is inserted into the keyhole 43 of the lock unit 41.
4 is inserted, the rotor 42 is rotated, the lock plate 45 is retracted, and the locking projection 26 and the lock plate 4 are inserted.
Release the engagement of 5. At this stage, in the push-type button unit, since the locking claw portion 20 of the tip end portion of the handle 18 is engaged with the rear surface 32 of the push button 30 on the base end side, the handle 18 is still held in the retracted position. It has been done.

When the operator pushes the front end portion 33 of the push button 30, the push button 30 rotates about the transverse pivot shaft 39 against the bias of the posture holding spring 40, and the base end of the push button 30. The engagement between the rear surface 32 on the part side and the locking claw portion 20 is released, and the handle 18 instantly projects from the front concave portion 3 of the casing 1 by the action of the drive spring 38.

As shown in FIG. 12, at the same stage as above, in the slide type button unit, the handle 1
The locking claw 20 at the tip of the button 8 is the locking projection 68 of the button 65.
The handle 18 is still held in the retracted position because it is engaged in the.

The operator puts his / her finger on the front projection 70 of the button 65 to resist the bias of the return spring 73, and the button 65 is pressed.
When is slid backward, the engagement between the engagement projection 68 of the button 65 and the engagement claw portion 20 is released, and the handle 18 instantly projects from the front concave portion 3 of the casing 1 by the action of the drive spring 38. The backward movement of the button 65 is suppressed by the stop projection 25 of the button case 24 and the stop projection 67 of the button 65 being pressed against each other.

As shown in FIG. 8, in the case of the push-type button unit, the handle 18 projects and the push button 30
When the pressure is released, the push button 30 is rotated about the transverse pivot 39 by the biasing force of the posture maintaining spring 40,
The locking claw portion 31 engages with the locking protrusion 25, and the push button 30 is aligned on the extension of the handle 18.

As shown in FIG. 13, in the case of a slide type button unit, the handle 18 projects and the button 65
When the finger is removed from the front protrusion 70 of the button 65, the urging force of the return spring 73 causes the button 65 to slide forward,
The side surface 69 of the above is pressed against the stopper 72 and returns to the original position.

When the protruding handle 18 is grasped and rotated in a predetermined direction, the locking shaft 11 connected to the handle 18 by the transverse pivot shaft 37 is supported by the shaft tube portion 2 and integrally rotates, and the stopper plate 3
6 is separated from the receiving portion 57 on the fixed frame body 56 side. Therefore, the door 55 unlocked from the fixed frame body 56 is
It is released by pulling the handle 18 toward you. Upon this opening operation, the lock housing portion 19 at the tip of the handle 18 is used as a suitable finger hook portion.

After the door 55 is closed and the handle 18 is rotated in the reverse direction so that the stopper plate 36 is engaged again with the receiving portion 57 on the side of the fixed frame 56, the handle 18 is pushed into the front concave portion 3 of the casing 1. At times, as shown in FIG. 9, in the case of a push-type button unit, the locking claw portion 20 at the tip end portion of the handle 18 pushes the base end portion 34 of the push button 30. By this pressing, the push button 30 once rotates against the bias of the posture maintaining spring 40.

When the push-in of the handle 18 progresses and the locking claw portion 20 at the tip of the handle 18 passes over the rear surface 32 of the push-button 30 on the base end side, the push-button 30 is provided with a posture-holding spring 40. The push button 30 is instantaneously rotated by the force, the locking claw portion 31 and the locking projection 25 are engaged, and the push button 30 is aligned on the extension of the handle 18. Locking claw 2 at the tip of the handle 18
0 engages with the rear surface 32 of the push button 30 on the base end side, and the handle 18 is held in the retracted position.

At the same time as above, as shown in FIG. 14, in the case of a slide type button unit, the handle 18
The locking claw portion 20 at the tip of the button pushes the locking projection 68 at the base end of the button 65. By this pressing, the button 65 is temporarily
It slides backwards against the bias of the return spring 73.

As the push-in of the handle 18 progresses, the locking claw portion 20 at the tip of the handle 18 becomes the locking projection 6 of the button 65.
When it goes over to the back side of 8, the button 65 has a return spring 73.
The side surface 69 of the button 65 comes into pressure contact with the stopper 72 and returns to the original position. The locking claw portion 20 at the tip of the handle 18 engages with the locking protrusion 68 of the button 65 to hold the handle 18 in the retracted position.

In this state, by inserting the key 44 into the key hole 43 and rotating the rotor 42 to advance the lock plate 45, the tip of the lock plate 45 is engaged with the locking projection 26 of the button case 24. Again, as shown in FIGS. 6 and 11, the handle 18 is accurately locked in the retracted position, and the door 55 is locked to the fixed frame body 56.
