Next, the handle main body 71 is grasped by hand, and is rotated counterclockwise (in the arrow direction) about the notched disk 69 as shown by the solid line in FIG. By this operation, the shaft portion 80 rotates in the same direction together with the notch disk 69, and the latch 88 attached to the shaft portion 80 by the screw 86 rotates counterclockwise. Therefore, this latch 8
8 is disengaged from the stop frame on the side of the housing 59, and then the handle body 71 is pulled toward you, whereby the door 51 of the housing 59 is opened. Also, the closing door is such a door 51
29 and FIG. 3 by performing the opening operation of FIG.
It can be easily performed in the state shown in 0. 32 and 33.
Shows an exploded view similar to that of the conventional example and a state of mounting operation on the door.

On the other hand, as prior art, there are FIGS. 34 to 37 in addition to the above-mentioned FIGS. 27 to 33. The difference between FIGS. 34 to 37 and FIGS. 30 to 33 is that when the latter rotates the latch 88, the lock 74 is unlocked and then the push button 75, which can be pushed in, is pushed in the clockwise direction. The handle main body 71 is flipped up at 79, and then the handle main body 71 is rotated about 90 ° and the latch 88 is rotated to remove it from the housing 59. In the former case, when the push button 75 that can be pressed by unlocking the lock 74 is pushed against the spring 77 ′, the locking portion 95 of the handle body 71 that was engaged with the push button 75 is released, and the handle 79 is released by the spring 79. Jump up. At the same time as the upward movement, the hook 105, which is the protruding portion protruding from the cloud-shaped hole 95, rotates right about the shaft 102 to push down the hook 105 protruding from the cloud-shaped notch 95, and 88 rotates clockwise around the operation pin 107 and descends downward until the action pin 109 hits the upper side of the hole 95. In this way, by simply flipping up the handle with the spring 79, the latch 88 is lowered and then the door 51
The main body 59 can be opened. Screw holes for attaching to the door 51 and screws 93 and 94 are provided in the upper and lower portions of the handle case 61.

By the way, as shown in FIGS. 28 and 33, the back side (inside of the door) of the above-described conventional lever handle or flat handle is arranged from the outside of the door 51 to the handles 52, 71. The latch 88 is detached from the main body 59 by rotating, and is not configured to be easily detached from the inside. For example, when an outside worker accidentally closes and locks the door on a distribution board where a person enters inside and works, or in a condominium PS, storage box, etc., which is closed and has no other doorway. When the door 51 is fastened with the latch 88 in the case of escaping from the inside to the outside, it may be difficult to escape to the outside due to the fastening force. Further, in the case of FIG. 35, unless the screw of the operation pin 107 is removed with a tool (not shown) or the like, it cannot be escaped from the inside of the door to the outside.
