Specific embodiment

Hinge 1 includes first axle part 2, which, which has, is securable on Furniture Body or household electrical appliance Bearing 3, hinge arms 4 are hingedly installed on the bearing.The tectonic axis 5 on lobed socket 3 thus, rotatably pacifies on axis 5 Hinge arm 4.It can also by having, there are two the joint institutions of lever to be rotatably mounted hinge on the first axle part Arm 4.

In addition, hinge 1 further includes the second hinge part 6 that can be fixed on door or trap.Second hinge part 6 thus With plate 7, which has mounting hole 70.The cup-shaped recess surrounded by two side walls 8 is also in addition constructed on second hinge part 6 9, to accommodate the end section of hinge arms 4.Setting may be inserted into the positive gap 13 of hinge arms 4 in the region of the recess 9.

As shown in Fig. 2, in order to which first axle part 2 is mounted on second hinge part 6, first hinge arms 4 towards recessed Mouth 9 moves, wherein being configured with guide surface 10 on opposite side wall 8, the recess 11 of channel-shaped is configured on the guide surface.It is cutting with scissors Round and smooth protrusion 12 is provided on opposite side 16 on chain arm 4, wherein protrusion 12 is inserted into when being inserted into hinge arms 4 In channel-shaped recess 11.

In hinge arms 4, two prominent laths 17 additionally are structured on front, the wherein lath 17 is inserted into In the gap 13 of second hinge part 6.

It is L-shaped that hinge arms 4, which are configured to side, and including plate end 15, pawl is rotatably mounted on end 15 18.Pawl 18 is maintained on axis 19 thus, and axis 19 is configured on end 15.Pawl 18 is connected herein with pusher dog, by Pawl 18 can be moved in the pusher dog.

It is shown in FIG. 3 installation site of the hinge arms 4 on second hinge part 6, wherein pusher dog 20 can be along leading It is deviated to face 14, wherein guide surface 14 is configured on the side wall 8 of second hinge part 6.End 15 is inserted into hinge arms 4 When, pusher dog 20 is shifted by along guide surface 14, and wherein pusher dog 20 is moved towards end 15, so as to pawl 18 overcomes the power of spring and it is inclined Turn, as shown in Figure 4.In Fig. 4 pusher dog 20 almost have passed past guide surface 14 and on second hinge part 6, and positioned at locking Position slightly before, wherein after the latched position upper poking claw 20 is locked in guide surface 14.Position before locking is slightly In, pawl 18 is highlightedly arranged relative to the adjacent surface 22 in hinge arms 4, so that can visually know well Do not go out hinge arms 4 not lock on the second hinge part 6 also.In Fig. 4, in order to more intuitively cut away part hinge arm 4 herein.

There is no pusher dog 20 and guide surface 14 and existing danger is, for example if hinge arms 4 are difficult to be inserted into second hinge In part 6, then in locking process, pawl 18 is just accurately held on rib 140.Although hinge 1 seems to be locked in In the position next time, but when this pawl 18 can shake from rebound on the rib 140, and hinge 1 unlocks.The state also by Referred to as " spurious lock ", and can result in and propped up.

In order to reliably avoid this " spurious lock ", guide surface 14 has certain length, if it ensure that pawl 18 It can deflect into below the contact surface 141 of hinge fraction 6, then the pawl 18 is discharged to be locked by pusher dog 20.
