Description

Be used in particular for the safety lock of the type with deadlock plates of armoured door

Technical field

The present invention relates to a kind of safety lock that is generally used for door, gate, strongbox etc. with high use flexibility ratio.

Background technology

Known in the building site, the door in the room in the construction is provided with the lock that at least one is used for the type of armoured door, makes to have many locks on whole building site, is unlocked or closes according to these locks of work that carry out in the house or finish.

The residual at first therein building site that has need of work to carry out (for example can be the work that their internal work is finished in the work of pipeline or electric type or be used to), need not to be to use master key (promptly being handed over to room owner's last key) to open the room, but (for example) uses so-called " building site key " (promptly being retained in the key in the workman's hand that freely enters the room) to open the room.

Sometimes, except master key and building site key, so-called " service key " also is provided, and the dwelling house owner can be handed over to described service key (for example) it can rely on and allow freely to enter room (for example) to carry out the people of necessary every day of cleaning subsequently.

Therefore, the building site key can not just in time have the purposes of the permission of service key and/or master key.

Therefore, according to foregoing, each lock by the door that exists on the building site all is provided with building site key, service key and master key, if the groundwork in the room is finished according to this sample loading mode, thereby make only to prevent that the people that may rely on from entering the room that so described master key can be got rid of the possibility of using the building site key equally with the service key.

Can open all locks in all rooms of existing on the building site although should be noted that the building site key, serve key and master key and be merely able to exclusively open the lock that they mate.

For above-mentioned reasons, so there is the lock of three kinds of main types on the market at least, described lock uses building site key and master key and may serve key.

For example, the lock that prior art is known a type, it has the mechanism of the part operation opening and closing that are included in the interim pulley with the part that is made of plastics, and has the cost that comprises especially.

If finished all building site activities, so interim pulley is comprised that the last pulley that design is used for using new mapping relations to recover a cover lever of lock replaces.

Owing to need influence the fact of door (its task) by removing thread escutcheon, so the shortcoming that this scheme exists is very general for being undertaken by the professional.

Consider lock (a kind of door that is used for the on the left side unlatching that needs to need to use last pulley to replace interim pulley for a long time and consider two types of needs, a kind of door that is used for opening on the right, thereby usually only carry out aforesaid operations in the inside of door) the fact, the composition of described lock significantly increases.

At last, be pointed out that the lock of described type must installed the site rather than test in factory, this mounting means can produce all shortcomings.

The lock and the above-mentioned lock of another kind of type are substantially similar, use last pulley to replace interim pulley but whether design, and it only designs the element that replacement can change the mapping relations of lock.

Therefore, with above-mentioned phase-locked ratio, basically replace the mapping part following of the condition of lower cost, be still so even still exist under the shortcoming (for example in the workshop, do not carry out but directly the tolerance difference that the general fact of carrying out in the site causes is being installed, thereby causing meaning for action need takes off shortcoming to install with lock) owing to test.

But the another kind that uses at present lock is the lock of recompile type, and it has building site key and master key.

In this case, therefore the dismounting lock does not remain unchanged on the moment that is locked in installation of installing.

In such lock, by special step and the special instrument of use, master key can be adapted mapping relations in such a manner again, makes to get rid of and uses the building site key, therefore only can use master key.

The shortcoming of such lock is the general higher cost of code device, to such an extent as to the lever of its composition or plate also must also move in the horizontal direction to improve new coding by special instrument except having to vertical direction moves.

Therefore, the very complicated and often obstruction easily of the mechanism of described lock.

Summary of the invention

Task of the present invention is to eliminate the above-mentioned shortcoming that relates to prior art and list.

Especially, in the structure of task of the present invention, free-revving engine of the present invention provides the lock of the not expensive basic system of use and the building site key all identical with all locks in building site.

Another object of the present invention is at the instrument that does not use any kind, does not need professional's intervention and do not need opposite house on-site to testing but can test in factory and have under the condition of all advantages that following scheme can provide a kind of lock is provided, and this lock can be got rid of the building site key and/or serve key by simple especially and functional system and mechanism in automatic mode.

Another purpose of the present invention provides a kind of lock, and this lock can be not specific and produce that neutral zone under the condition of lever or deadlock plates is used for the opening on the left side especially or opening door on the right.

Of the present invention is not that least important purpose provides a kind of lock, this lock can use a large amount of mapping relations, thereby produce different locks, promptly may provide a large amount of locks, to such an extent as to the building site key plays a role according to mode complete and that jam plate (plate of the lock) is irrelevant.

By being provided according to claims 1, safety key finished technical assignment and recited above and other purpose.

In addition, additional features of the present invention also limits in claims.

From appended accompanying drawing plate, only by shown in the schematic and non-limiting example according to safety lock of the present invention preferably but the not description of the embodiment of exclusiveness, further characteristics and advantages of the present invention are will be more obviously apparent, wherein:

The specific embodiment

With reference to last figure, safety lock is shown by being appointed as reference marker 1 on the whole.

Lock 1 (preferably but be not to be necessary for the four-throw type) comprises that the box-like housing 3 of rigidity, its inside exist each other and connects floor spring door bolt 4 and snap member 5 on the kinematics.

The plate 14 that is used to cover box-like housing 3 has keyhole 13, and described keyhole 13 is used for an introducing with a plurality of keys that can operable lock 1.

In the keyhole 13 of safety lock 1, can introduce: the first key 2a, it can also operate other locks; At least one second key 2b, it is operable locks 1 only; And also preferred at least one the 3rd key 2c, it is operable locks 1 only.

Snap member 5 is supported plate 6 carrying, the retrieving position that is used to open lock of its snap member 5 in box-like housing 3, corresponding to the partly pull-out location of the pass locking of two cranks and fully moving horizontally between the pull-out location corresponding to the pass locking of four cranks.

Spring bolt 4 is used to open the retrieving position of lock and is used to close between the pull-out location of locking move horizontally successively in box-like housing 3.

There is the legacy system be used for mobile spring door bolt 4 at least in lock 1, and this system comprises: be used for pivot is placed on the lever 11 that spring bolt 4 on 12 is pushed box-like housing 3 to; And the mechanism that is used for the Momentum Transfer of key is given specified lever 11.

Stacked a pile deadlock plates or gorge 7 on the base plate 6, each deadlock plates or gorge 7 move in the mode of vertical translation and have window 8, and described window 8 has the tusk of qualification corresponding to the passage recess 9 of the coding of the key of lock 1.

In order to support snap member 5, the deadlock element 10 or the wheel rim that are arranged on window 8 inside are fixed on the plate 6.

Especially, each deadlock plates 7 has five recesses, and described recess is divided into and is used to drive second and the recess X of four-throw and spring bolt 4 and be used to drive first and three-throw recess Y of snap member 5.

According to significant aspect of the present invention, lock 1 comprises: be used to device that the first key 2a was lost efficacy, its can be at least by the second key 2b with can also be operated by the 3rd key 2c especially; And no matter deadlock plates 7 and drive and to be used to close locking 1, the particularly device of at least a member of spring bolt 4.

Therefore, key 2b and 2c work to deadlock plates 7, show open channel thereby make the tusk of window 8 produce one, thus deadlock element 10 slip that is activated in described passage.

On the contrary, key 2a works to deadlock plates but does not make the tusk of window produce coupling, therefore open channel not.

No matter the device of deadlock plates 7 and driving spring door bolt 4 comprises at least one cam 15, described cam 15 is activated by the first key 2a and the protuberances of the plate 17 of spring bolt 4, particularly support spring door bolt 4 itself is worked.

Therefore, according to particularly advantageous aspect, spring bolt 4 not only can drive by lever 11 (device of the second key 2b and the 3rd key 2c) in known manner, and can be independent of by the driving of lever 11 and additionally drive by cam 15.

Cam 15 and lock 1 twisting, and have at least one tusk 18, described tusk 18 can mesh with at least one anti-tusk 19 of the first key 2a.

The first key 2a can make cam 15 rotate between the pull-out location of spring bolt 4 and retrieving position.

Especially, cam 15 is by the device and overlay 14 twistings of box type body 3 of hinge pin 20, described hinge pin 20 spool promptly with the common horizontal translation direction quadrature of snap member 5 and spring bolt 4, again with the vertical direction quadrature of the displacement of deadlock plates 7.

Cam 15 can be opposite with twist mode back-moving spring 26 and the effect by twist mode back-moving spring 26, be driven, is wound on the hinge pin 20, driven towards box shell body 4 at opposite side towards cam 15 in a side by the first key 2a, and this is easy to make its pull-out location towards spring bolt 4 to return automatically.

Ineffective part instead comprises saddle 21, described saddle 21 is at least by the second key 2b with preferably also by at least the three key 2c activation, and described saddle 21 has the element 22 with engagement, and described element 22 is designed to make it can be arranged on the opposite direction rotation of the direction of motion on the cam 15 with key 2a.

Saddle 21 obtains from the same plate 6 of supporting snap member 5.Engaged element 22 was initial position (Fig. 2) (remaining valid at the first key 2a under this position), centre position (Fig. 4) (losing efficacy at the first key 2a under this position) and final position (Fig. 5) (the first key 2a lost efficacy at last under this position) temporarily.

In initial position, engaged element 22 breaks away from cam 15 in such a manner, makes conduct because the result of anti-tusk 19 rotation of driving cam 15 with the engagement of the tusk 18 of cam 15 of the first key 2a can freely regain spring bolt 4.

At centre position place, engaged element 22 is towards cam 15, thereby it is rotated to the opposite mode of retrieving position as the result of the anti-tusk 19 of the first key 2a and the engagement of the tusk 18 of cam 15 and from the pull-out location of spring bolt 4.

At the place, final position, 15 rotations of engaged element 22 driving cams are set in the position of inactivation forever up to it, and it no longer works with the first key 2a in this position.

Move on the contrary with spring 25 and to the column bolt 24 of spring 25 generation effects by cam 15 supportings and the bearing 30 places engagement that is designed for lock 1, particularly plate 14 being used to cover box type body 3, thereby cam 15 is suppressed at its invalid position place.

Advantageously, the first key 2a is the building site key, and the second key 2b is a master key, and the 3rd key 2c is complementary service key.

In this manner, master key is designed in the rotation of predetermined quantity or gets rid of the building site key after starting at last and automatically and interim and automatically get rid of the service key.

The service key is designed for successively in the rotation of predetermined quantity or after starting gets rid of the building site key temporarily and automatically, and the quantity of described rotation or startup is lower than master key and gets rid of the quantity of rotating or starting under the condition of building site key at last and automatically.

Basically, lock 1 can make key lose efficacy with improving, and wherein said key operated described lock 1 makes each key because another has the key of different coding and automatically at last or interim the inefficacy.

At lock 1 is in the described situation of four-throw type, use has the building site key of one or two crank, the service key can automatically lose efficacy temporarily, and the building site key is when using following two cranks, and master key can automatically lose efficacy temporarily and serve key inefficacy automatically at last.

Each key 2a, 2b, 2c are preferably but must not be the double head type key.

Except anti-tusk 19, the first key 2a also has two neutral heads (neutral bit) that can not make it drive deadlock plates 7.

Key 2b and 2c instead have corresponding to first of recess X with corresponding to second of recess Y, and each head all has and deadlock plates 7 as many recesses.The zone line of key 2b and 2c does not have coding and its purpose to be to drive in the mode of horizontal translation the plate 6 of supporting snap member 5.

Two statures of key 2a, 2b and 2c repeat, and with respect to the center Rotate 180 of key °, reason is that deadlock plates 7 and cam 15 are provided with asymmetricly in box shell body 3.

Below the concise and to the point operation of describing lock 1.

Lock 1 is initially in the structure of Fig. 2: even snap member 5 is regained, spring bolt 4 is pulled out and is made lock 1 be closed.

By key 2a being inserted keyhole 13 and rotating, anti-tusk 19 works for the tusk 18 of cam 15, therefore drives (rotation in the counterclockwise direction as shown in FIG.) in rotary manner.In rotation, cam 15 is the protuberance 16 of slurcam 17 successively, thereby spring bolt 4 is regained till lock 1 is unlocked (Fig. 3).In this motion process of cam 15, column bolt 24 slides in the arcuate slots 27 of plate 14, and the flexural center of described arcuate slots 27 is on rotary pin shaft 20.

Structure from the lock 1 of Fig. 2, if key 2c inserts keyhole 13, behind two locking cranks, saddle 21 moves to such position, engaged element 22 meshes (Fig. 4) with the shaft shoulder 23 of cam 15 in this position, therefore suppresses cam 15 and rotates on the direction that spring bolt 4 is regained.Therefore, if as in the structure of the lock 1 of this back, key 2a inserts in the keyhole 13 once more, under any circumstance key 2a can not regain spring bolt 4, to causing cam 15 to be blocked.Only have two key 2c that open crank and can activate key 2a again.

Structure from the lock 1 of Fig. 2, if key 2b inserts keyhole 13, when carrying out the second two locking cranks, 21 of the saddles enough degree for engaged element 22 of advancing, mesh by the shaft shoulder 23 with cam 15, cam 15 is shifted onto the position (Fig. 5) of inactivation: in the rotation of cam 15, thereby column bolt 24 is regained the reaction force that has overcome spring 25, make from groove 27, to come out, continue to penetrate bearing 30 by the button effect then, thereby cam 15 is remained on the position of inactivation.In this position, cam 15 can not interact with key 2a, thus last the inefficacy.Key 2c lost efficacy temporarily in addition, thereby caused the coding of two cranks different with the coding of four cranks of key 2b.Therefore, key 2c only just activates again when opening crank one or two that starts key 2b.When starting four unlatching cranks below, key 2a keeps losing efficacy, and reason is that as mentioned above cam 15 remains on the position of inactivation.

Use not expensive basic system according to lock of the present invention, on the one hand all locks are all identical on building site key and the building site, on the other hand the instrument that does not use any kind, do not need professional's intervention and do not need on-site opposite house to the condition of testing under can with automatic mode by especially simply and functional system and mechanism get rid of the automechanism device.

Can neutral zone be used for the opening on the left side according to lock of the present invention with opening door on the right.

Be not least important, can provide a large amount of locks, to such an extent as to the building site key plays a role according to mode complete and that jam plate is irrelevant according to lock of the present invention.

In fact, the material of use and size can be the states of any requirement according to prior art and definite.
