The specific embodiment

With reference to each accompanying drawing, Reference numeral 1 always indicates an emergent lock.

The lock 1 that is used to reinforce door comprises the housing case 2 of box shape, housing 2 is configured as substantially as a parallelepiped and two mutual opposite faces with big surface 3 and four lateral edges, i.e. top edge 4, lower limb 5, leading edge 6 and back edge (not shown) is arranged.Box shape housing 2 can be made by the standard size specification that adopts such lock, and its advantage is can be installed on the door of any reinforcing, and needn't do any change to it.

Box shape housing 2 is provided with suitable several lateral openings 7, pass through at least one dead bolt 8 and at least one lock pin 9, according to illustrated embodiment, at least one above-mentioned lock pin 9 is made of four cylindrical elements, and they are arranged to parastate and can laterally slide with respect to lock 1.In order this lockset there to be to prevent the safe enough degree of the attempt of forcing open the door, also can make such lock embodiment: it is provided with the additional lock pin that can stretch out from top edge 4 and lower limb 5, to be associated with each drive link, each drive link is suitable for driving and can does translational motion and be arranged to and lock 1 that one section bar bar of distance is arbitrarily arranged with respect to door; Can also allow lock 1 have only the single lock pin 9 that large-size arranged alternatively (or constitute by the part of any amount of Any shape and/or size).

Box shape housing 2 is holding the part of a plurality of en plaques basically, and these parts are associated with the lock core 10 with corresponding key actuated on function.

Also be provided with a rotational parts 11 for the handle joint in the housing 2, rotational parts 11 is associated with above-mentioned at least one dead bolt 8 and is designed to be able to make above-mentioned dead bolt motion by the suitable lever system of known type.

Lever system between rotational parts 11 and dead bolt 8 comprises tilting bar 12, and one end 13 can be associated with dead bolt 8 and can make its motion.

Tilting bar 12 is provided with at least one bottom 14, in order to cooperate with at least one the corresponding adjacent part 15 that supports that is connected in rotational parts 11 rigidly.

Tilting bar 12 can tilting, and its motion is that the action by the drivable mechanism of user realizes, this action can be with tilting bar 12 with respect to its end 13 from one first state tilting to, second state that is elevated, at first state, its bottom 14 and adjacent part 15 substantial registration of supporting, and at second state, bottom 14 breaks away from and is interval in adjacently to be supported part 15 and not to interfere with it in any point that the neighbour supports the stroke of part 15 in the rotation process of rotational parts 11.

Be used to make the driving mechanism of tilting bar 12 motions to comprise pivot rotaring lever 16, it is pivoted on the base plate 17 that is used for lock pin 9, it has a lobe 18, and this lobe is aimed at when lock pin 9 is return, interfered near the shifting block 19 of lock core 10 and with respect to its stroke and shifting block 19.

Rocking arm 20 be pivoted on box shape housing 2 and the teat 21 that rests on basically on the pivot rotaring lever 16 is arranged and substantial registration in the upper end 22 of the lower limb 23 of tilting bar 12, tilting bar 12 is remained on second state that is elevated when resting on the upper end 22 (being inserted with other part therebetween alternatively) at lower limb 23.

Pivot rotaring lever 16 comprises the body 24 of strip basically, and it is provided with through hole 26, is used to admit the pivot that is associated with base plate 17.Lobe 18 is the bottom that is in pivot rotaring lever 16 to lock core 10 bendings and at confined state basically.Lobe 18 those sides are provided with the lateral-supporting wing 27 of the teat 21 that is used for rocking arm 20.If look up from beneath at confined state, rocking arm 20 comprises that end is with 28 and central shaped profile plate 29, and end is installed on box shape housing 2 with 28 end pivot.Teat 21 laterally stretches out from a side of median plate 29.Median plate 29 is provided with transverse groove 30 and groove 32, and groove 30 is in alignment with the bearing pin 31 of the base plate 17 that is connected in each lock pin 9 rigidly, and groove 32 is admittance fixed leg 33 then, and upper end 22 (preceding describe) is suitable for cooperating with the lower limb 23 of tilting bar 12.

Tilting bar 12 comprises: the through hole 34 at its 13 places, end is used to admit the axis of guide 35 that is connected in housing 2 rigidly; Middle body 36, bottom 14 cooperates to support part 15 with the corresponding neighbour who is connected in rotational parts 11 rigidly from this middle body is outstanding; And the terminal bar 25 that is used for the upper end 22 of support arm 20.

Dead bolt 8 remains on the state of stretching out by suitable elastic device 8a and is associated with driving element 37 when normality.

Tilting bar 12 according to first state arrangement and thereby be when positively being lowered, the end 13 of tilting bar 12 stably cooperates with driving element 37.

Be easy to notice in this embodiment shown in the drawings, the distance piece 38 of insertion is arranged between bar 25 and the termination 22 endways, it is connected in each one of the part of en plaque basically that is associated with lock core 10 on function rigidly.

The operation of lock 1 of the present invention is as follows:

At first, it will be noted that in lock 1, when lock pin is return fully, can not dead bolt 8 be return by rotating the key that is inserted in 10 li of lock cores to the direction that each lock pin 9 is return.So this is a kind of lock of specific type, in this lock, only just can makes dead bolt 8 motion, and have only and just can make behind the shifting block 19 of rotational lock core 10 each lock pin return and/or stretch out by the handle that is engaged in rotational parts 11.

Common situation is, the rotation of rotational parts 11 and the rotation of handle are complementary, and the neighbour of rotational parts 11 supports part 15 and acts on bottom 14, and tilting bar 12 is return, dead bolt 8 thereby return.

In this case, tilting bar 12 is by leaning against on the distance piece 38 and slide, and distance piece 38 is again to be arranged on the upper end of termination 22.

Because two parts that rotational parts 11 can be arranged to face one another and aim at, even be received in inner handle in the interior part of rotational parts 11 and be effectively (active), be received in outdoor handle in the outer part of rotational parts 11 and be yet invalid (free), so that any motion of this handle can not make dead bolt 8 motions.

If desired outdoor handle (and therefore outer part of rotational parts 11) is associated (it is effective making outdoor handle) with dead bolt 8, just must when being return, each lock pin 9 make shifting block 19 motions, with further rotation it is further return, thereby shifting block 19 forces lobe 18 upwards, also support fins 27 being raised, and support fins 27 is raised the teat 21 of rocking arm 20.

Raising of teat 21 makes rocking arm 20 be with 28 to rotate around end, this rotation makes termination 22 break away from distance piece 38 and leaves the lower limb 23 of terminal bar 25, distance piece 38 and terminal bar 25 are in the state of reduction, at this state, end 13 driven elements 37 of tilting bar 12 connect, and end 13 motions that dead bolt 8 return just can make tilting bar 12.

Can recover to make the disengaging of outdoor handle and dead bolt 8 by the key that rotation is inserted in 10 li of lock cores.

This rotation can make each lock pin 9 stretch out and guarantee to make base plate 17 motion, and the result raises tilting bar 12 to leave rotational parts 11, thereby it is not in support the state that part 15 interferes with the neighbour; Any motion that this no interference state can guarantee to be inserted in the outdoor handle in the corresponding outer part of rotational parts 11 can not be delivered to dead bolt 8 by any way.

Like this, as can be seen, the present invention has reached the target and the purpose of anticipation.

The present invention to such design is easy to make various changes and modification, and all these belongs within the appended claims scope.

All detailed structure also on the available techniques other structure of equivalence substitute.

Shown in exemplary embodiment in, each feature that provides with each object lesson relevantly in fact can by with other exemplary embodiment in other different characteristic exchange.

And, it should be noted that, in applying for a patent process, be found to be known anything and all can be regarded as and to be advocated right thereby be the theme of abandoning.
