Locked.

Thus, by pushing the pair of button members 127 and 127, the clutch piece 225 enters the cylindrical portions 169 and 187 of the handle main bodies 161 and 163, and the rotation trajectory of the third protruding piece 155 of the operating member 131. Arranged above, the clutch piece 225 and the actuating member 131 are engaged, and as a result, the handle body 125 and the shaft member 123 are engaged. By rotating the handle main body 125 in this state, the operating member 131 can be rotated and unlocked. Then, the door can be opened in the unlocked state.
Further, after unlocking, when the hand is released from the handle 121, the left end portions of the button members 127 and 127 are vertically separated by the urging force of the spring 223, whereby the pin 219 of each button member 127 is moved vertically of the clutch piece 225. It moves to the groove parts 229a and 231a, and the clutch piece 225 also returns to the initial position. Furthermore, the handle body 125 and the shaft member 123 are also automatically returned to their initial positions by the springs 211.

In the second embodiment, when the handle main body 125 is rotated without operating the button members 127 and 127, the handle main bodies 161 and 163 are rotated until the handle main body 125 is rotated by a predetermined angle α as in the first embodiment. The handle main body 125 rotates relative to the shaft member 123 (i.e., idles) until the projections 173 and 195 of the first and second protrusions 173 and 195 come into contact with the first projecting piece 151 of the actuating member 131. As a result, it cannot be unlocked.
Therefore, like the handle 1 of the first embodiment, the handle 121 of the second embodiment can prevent unauthorized unlocking. In addition, after the handle body 125 idles until the projections 173 and 195 of the handle bodies 161 and 163 come into contact with the first projecting piece 151 of the operating member 131, the shaft member 123 rotates when the handle body 125 further rotates. Can be unlocked. That is, even when the handle body 125 is rotated without operating the button members 127 and 127, the handle body 125 can be unlocked by rotating the handle body 125 by a predetermined angle or more. Therefore, even if the operation of the button members 127 and 127 is forgotten and the handle body 125 is rotated in the event of an emergency such as a fire, it can be unlocked and escaped.

  In the second embodiment, the clutch piece 225 does not move when only one of the two button members 127 and 127 is operated, and the clutch piece 225 and the actuating member 131 are not engaged. For example, even if only the upper button member 127 is pushed in and unlocked from the state of FIG. 15, the pin 219 of the lower button member 127 biased by the spring 223 is caught in the longitudinal groove 229 a of the clutch piece 225. Thus, the clutch piece 225 cannot move. As a result, the clutch piece 225 and the operating member 131 are not engaged, and the handle main body 125 is kept idle with respect to the shaft member 123. Even in this state, the handle body 125 can be unlocked by rotating it by a predetermined angle.
