Embodiment shown in the figure, fixed housing 1 is from the positive installing hole that embeds door 14 of door, and front end boss portion 32 is connected on the door 14, and it is fastening to prop up seat board 30 and screw 31 with the U font.The support 8 of lock shaft 3 fronts is made of hemispherical concave depressions, pole shape spring-loaded body 7, make hemispheric base end part and be stuck in wherein.Pair of bearings plate 15 forwards is equipped with in both sides at bolster 8, is stuck in the outside of the pair of bearings plate 16 that is based in the handle 4 base end part back sides.Cross pivot 5 and pass these shaft bearing plates 15,16.Spring-loaded body 7 is configured in the space between the pair of bearings plate 16,16, and supporting pivot pin 10 crosses shaft bearing plate 16,16.Spring base 12 is discoid, and the spring base projection 13 of round flange shape is made one with spring-loaded body 7.

Be equipped with finger push and block portion 17 in the base end part front of handle 4, be equipped with hammerlock 18 at the front end back side of handle 4, when handle 4 sank to, hammerlock 18 was connected on the inner bottom surface 19 of fixed housing 1.At the front end of fixed housing 1, bury the rotor 20 that the tapered end unit is housed, be provided with eccentric projection 21 at the back side of rotor 20.Taken in slide block 22 near rotor 20 on fixed housing 1, slide block 22 makes it have the trend that the direction to rotor 20 moves by compression helical spring 23.Be provided with and stop recess 24 engagings of hammerlock 18, the retention tab 25 of separating in the front of slide block 22.

When the key 27 with regulation inserts in the keyhole 26 of rotor 20, rotor 20 is revolved when turning 90 degrees, at Fig. 5, because eccentric projection 21 moves downwards, so slide block 22 moves identical distance under the pushing of compression helical spring 23, the retention tab 25 of slide block 22 breaks away from the stop recess 24 of hammerlock 18.Therefore, the locking of relative fixed shell 1 of handle 4 is disengaged.At this moment, when pushing the finger push and block portion 17 of handle 4, as shown in Figure 5, handle 4 is center clockwise direction rotation to cross pivot 5, stretches out from fixed housing 1.

In the way that this rotation is stretched out, because supporting pivot pin 10 is crossed the straight line that connects support 8 and cross pivot 5 in front, so, compression helical spring supporting pivot pin 10 is positioned at the position near central handle 4 cardinal extremities, therefore, turning moment handle 4, that produced by compression helical spring 11 is reverse.Because its ratchet effect, handle 4 has outwardly directed trend, extend out to the angle of regulation from fixed housing 1 quickly.

At Fig. 1, when holding the handle 4 during that remains on extended position to counter clockwise direction rotating handles 4, be embedded in the lock shaft 3 rear end square shaft portions 28, with bolt 29 fastening stop steel plate 6 break away from the locking pin seat of fixed frames 32 sides.

Detent mechanism of the present invention is not limited to the door locking handle assembly shown in the figure, if handle relative fixed shell has two stable states, then also can be applicable to the door locking handle assembly of other form of structure.

As mentioned above, the detent mechanism of door locking handle assembly of the present invention, because: the base end part of spring-loaded body 7 waved be bearing in freely on the support 8 that is arranged at lock shaft 3 fronts; The peristome 9 of the length direction of spring-loaded body 7 front ends is stuck on the supporting pivot pin 10 that is arranged at the handle 4 cardinal extremity back sides; Compression helical spring 11 is embedded on the spring-loaded body 7; Compression helical spring 11 is compressed between the spring base projection 13 of the spring base 12 that is embedded in movably on the spring-loaded body 7 and spring-loaded body 7 cardinal extremities, thereby spring base 12 is crimped on the supporting pivot pin 10; In the time of in handle 4 sinks to fixed housing 1, connect support 8 and the straight line that crosses pivot 5 relatively, supporting pivot pin 10 is positioned at the position near the cardinal extremity of handle 4, so, handle 4 bears the turning moment that sinks to direction that is produced by compression helical spring 11, thereby can stably remain on the state that sinks to originally.

In addition, because at handle 4 when fixed housing 1 stretches out, connect support 8 and the straight line that crosses pivot 5 relatively, supporting pivot pin 10 is positioned at the position near the front end of handle 4, so, handle 4 bears the turning moment of stretching out direction that is produced by compression helical spring 11, thereby can stably remain on the state that stretches out originally.

Cross the straight line that connects support 8 and cross pivot 5 at supporting pivot pin 10 when a side arrives opposite side, the direction counter-rotating that the revolving force that compression helical spring 11 produces is short, therefore, can do needed ratchet action, so can simplify the planform of detent mechanism part, can reduce manufacturing, the processing charges of whole device.

This detent mechanism because compression helical spring 11 whole total lengths all are embedded on the spring-loaded body 7, so the power of compression helical spring 11 all is converted into the turning moment of handle 4, can be done the ratchet action with needed power exactly.
