PROBLEM TO BE SOLVED: To provide a door lock handle device capable of shutting a door when an operation handle is at any rotational position.SOLUTION: Trying to shut a door 52 in a state in which an operation handle 5 is at a half open position or a closed position makes a circular conic slope 10d of the rear part of a latch body 7 come into slide contact with a slide surface 9b of an engaging pin 9 to push the engaging pin 9 to a non-engaging position, inhibiting the latch body 7 from having a collision with the engaging pin 9 to inhibit both of the latch body and engaging pin from receiving excessive stress. When the latch body 7 can path through the engaging pin 9; a spring 9a, concurrently with the passing, makes the engaging pin 9 protrude to an engaging position to engage with a first or second engaging recesses 10a, 10b. From this state, the door 52 cannot be opened unless the operation handle 5 is rotated to an open position.SELECTED DRAWING: Figure 2
【課題】操作ハンドルがどの回転位置にあっても扉を閉じることができる扉用ロックハンドル装置を提供する。【解決手段】操作ハンドル５が半開位置又は閉位置にある状態で、扉５２を閉じようとすると、掛金体７の後部の円錐斜面１０ｄが、係合ピン９の摺動面９ｂに摺接して係合ピン９を非係合位置へ押し上げるので、掛金体７は係合ピン９に衝突することがなく、両者が過大な応力を受けることがない。掛金体７が係合ピン９を通過できる場合には、通過と同時に、係合ピン９がばね９ａにより係合位置へ突出し、第１又は第２の係合凹部１０ａ、１０ｂに係合する。この状態からは、操作ハンドル５を開位置へ回転させない限り扉５２を開くことができない。【選択図】図２
