Technical field

The present invention relates to a kind of safety lock of controlling with bidentate key (Doppelbartschluessel) treated, it has a plurality of pivoted arms (Zuhaltung) that are arranged in the lock housing.

In addition, the present invention relates to a kind of key that is used to control safety lock, it has handle (Reide), handle (Halm) and key bit (Schluesselbart), is furnished with the coding with the key of the form of key level above that.

Background technology

The safety lock that is used for for example being installed in safety cabinet is known in the most different variants.The weakness of a plurality of known locks is that opening through the lock side utilizes proper tools to arrive the inside of lock so that handle the simple relatively possibility of pivoted arm at this.Therefore be fit to keep the lock opening as far as possible little, this decision key must be built littlely equally.For known so far lock, except itself the key of locking function that is used to lock, need be provided for activating the other key of pivoted arm adjustment (Umstellung) to the new locking in addition.

Summary of the invention

Therefore for the present invention provides a kind of purpose of safety lock, utilize it can realize the lock opening of constructing especially littlely, perhaps be reduced at the operation of adjusting the pivoted arm aspect significantly.

This purpose first variant according to the present invention realizes that thus promptly the bidentate key is with acting on unique device of adjusting pivoted arm and being used to control lockable mechanism.

Lock according to the present invention only key capable of using is operated.Bear simultaneously through key and to introduce adjustment, this key is used to control lockable mechanism on the one hand, and is used on the other hand reducing the turn over arm in the situation of no any additional instrument.Because key can take out in the adjustment position, lock advantageously also is provided in this position.

This is arranged to additionally, and set opening has the diameter between 9.5mm and the 11mm in the lock for key is introduced.For example in the safety cabinet structure when only at first being provided with a breach of constructing at the safe door place especially littlely, the size that is in this span approximately is favourable thus.At first from make reason as far as possible the time point in evening need confirm according to of the present invention combination lock or also have electronic lock whether to be loaded in the safety cabinet so.In lock housing and its safe door that is associated the set opening that is used to introduce key therefore can be especially little build, this mainly contains the raising that helps safety, because unlocking tool must be built equally and obviously more be difficult to operation littlelyr.9.5mm size at this corresponding to the minimum value that under static viewpoint, exists, size 11mm promptly under safety standard, does not allow to surpass 100mm for such opening under the situation of the added value of considering regulation ²Size.

The solution of considering for such lock (same therein key is used to control the lockable mechanism of lock and be used to adjust pivoted arm) is arranged to, and lockset has conduct to be used to adjust pivoted arm and/or is used to control the wheel hub (Nuss) of the element of construction of locking function.Such wheel hub relates to a kind of multifunction structure unit that has many functions.Except corresponding when controlling key the locking function itself; Wheel hub also born the pivoted arm in a plurality of steps adjustment control and bear the part of the function that acts on key or key bit in addition as the member of structure compactly, this especially relates to the interaction with pivoted arm outside the locking function of itself.Utilize such lock, can realize introducing the function of key adjustment with suitable key, with interrelating for example through rotating to the direction opposite with opening.

Be arranged to, wheel hub is provided with lock pin drivening piece (Riegelmitnehmer) that serves as the lock pin that is used for operated lock and/or the adjusting pin (Umstellzapfen) that is used to adjust pivoted arm.Realized the locking function of itself via the former, i.e. controlling when wheel hub rotates owing to key via lockable mechanism opening and closing lock.The latter is the part of element of construction that is used to control the adjustment of pivoted arm.

As element of construction, consider that about wheel hub lock pin drivening piece and adjusting pin are arranged in the back side (incoming direction at key is observed) of wheel hub, and have the wheel hub manufacturing integratedly in addition of lock pin drivening piece and adjusting pin according to the central authorities of lock of the present invention.

Be provided with particularly, the lock pin drivening piece is upwards observed laterally in the footpath of wheel hub and is arranged.In the rotation of correspondingly controlling key and wheel hub, realize the passing of opening or closing of lockable mechanism and this situation via this lock pin drivening piece.

This is arranged to additionally, and adjusting pin roughly makes progress, promptly arranges with the shape of circular arc in the footpath of wheel hub.When the lock pin drivening piece promptly will affact on the key moment of torsion when being delivered on the lock pin with its longitudinal side, the adjusting pin of on wheel hub, locating is diametrically shifted each member in the corresponding position onto when the adjustment function activation of lock, then also will study in great detail.

Another form of implementation of the present invention is arranged to, adjusting pin observe in the axial direction be arranged in before the lock pin drivening piece and/or the footpath of wheel hub upwards observe be arranged in the lock pin drivening piece after.This means on the one hand, after lock pin drivening piece (footpath at wheel hub is upwards observed) is positioned at adjusting pin.Be understood as at this on the other hand, adjusting pin (observing in the axial direction) is in more farther from the plane of wheel hub than lock pin drivening piece.Therefore, on the one hand aspect locking and on the other hand guaranteed not have defective aspect the adjustment of pivoted arm and function independently.

Be arranged in addition, wheel hub has with the auxiliary bourrelet of the introducing that acts on key.Preferably relate to one or more inclined-planes that are integrated in the wheel hub at this, it has caused the automatic centering of key.The bourrelet with the form in the hole in the shank of the key that this solution can make that the axle with case side interrelates becomes unnecessary.Advantageously, through in any situation set internal point of replacing do not produce have by crackle, convexity cause after the weakening of material of danger of damage.

Be arranged to aspect the adjusting of pivoted arm, the adjustment retainer (Umstellsperre) of supporting is used for activating the adjustment function that is locked into the enable possition movably on it is vertical.Its place, side in the face of housing wall at it has elastic portion.

Yet the adjustment retainer is not directly reaction when key rotates.And propose, adjustment rotating part (Umstellwirbel) is prepended to the adjustment retainer, and its activation realizes via adjusting pin.To this, key is in reverse in the adjusting of being planned of pivoted arm and opens the direction rotation normally.At this, wheel hub, adjusting pin extrudes rotatably mounted adjustment rotating part from its position more precisely; The adjustment rotating part is activated with the adjustment retainer.

Cause at this, the adjustment retainer makes the inside swing of adjustment rotating part become possibility in its enable possition.The latter constructs this with the adjustment retainer with corresponding to each other.The adjustment rotating part gets in adjustment retainer this, next locking the activation of adjustment.

Another favourable form of implementation of the present invention is arranged to, and pivoted arm jointly is associated with spring member, and it is responsible for the location of different pivoted arms.Replace single spring, be provided with that flexibly effect, compact and easy-on is with the member of the form of leaf spring on whole pivoted arms, it remains on pivoted arm in the neutral position like this, but is introduced in the lock with making the key no problem.

Be arranged in addition, housing is equipped with the guide portion that is used for pivoted arm.This guide portion is used to locate pivoted arm, and this guide portion and pivoted arm are constructed with corresponding to each other.In preferred form of implementation, when the axle in the cover plate that is integrated into housing was used as guide portion, this was such situation.When assembling lock housing, therefore axle locatees corresponding to pivoted arm.

What can consider is, pivoted arm has the opening corresponding to the axle structure, and it is around being the forced guiding for pivoted arm aspect the oscillating motion of axle.

Be provided with the baffle plate (Schuerze) (its as as operation protection with acting on the guide portion of key) of side direction through the key opening, it realizes dual-use function, grasps pivoted arm and significantly becomes difficulty through additionally making.

Another variant of the present invention is arranged to, and pivoted arm has the installed part of the size that is used to reduce this opening in the zone of the opening that is provided for introducing key.

Realize thus about the variant of key according to second in addition that according to the object of the invention promptly key bit has the key level in both sides, wherein, the diameter of key bit (about corresponding key level of giving prominence to the biglyyest) is between 9.5mm and the 11mm.

Therefore the coding of key constructs with compact especially formation, and wherein, it is similar to traditional bidentate key and is positioned on the key bit.The maximum gauge of key bit between 9.5mm and 11mm, is wherein understood spacing herein under maximum gauge, it is between farthest outstanding key level is on two or more relative sides at key bit.The lock housing with its being provided in the related door introduce the opening of key therefore can be especially little build, this mainly contains the raising that helps safety, operates because unlocking tool must be built equally and obviously more be difficult to littlelyr.9.5mm size at this corresponding to the minimum value that under static viewpoint, exists, the size of 11mm does not promptly allow to surpass 100mm for such opening under safety standard under the situation of the added value of considering regulation ²Size.When key bit has the key level and therefore constructs with the type of bidentate in both sides, also be favourable thus according to key of the present invention.But key since the little size no problem of tooth be inserted in the pivoted arm, add the space that need not be used for being present in addition the handle intercept between two and half teeth.Therefore, except the locking function, especially also be suitable for realizing the function of the introducing of key adjustment according to key of the present invention.

Be arranged in addition, the intercept of key bit and the shank of the key is constructed integratedly.Consider thus for example to have and hook mechanism (Einhakmechanismus), promptly be divided into the key of two-part handle, its part is associated with tooth and its another part is associated with handle.Two parts of handle are connected to each other via hooking mechanism then.The corresponding intercept of key bit and the shank of the key helps as common member fatefully, and however the key that has smaller size has essential stability.

Another advantage of the size design of the compactness of bidentate key is that it is possible obtaining the more favourable manufacturing approach of cost.For example consider, make with the metal dust injection moulding process by the element of construction that key bit and handle intercept constitute.The tooth of smaller ground design size can with handle intercept (tooth is associated with it) therefore jointly with the metal dust injection moulding process and obviously make more quickly or with few job step.

Characteristic of the present invention especially is, a kind of safety lock promptly is provided, and it satisfies the highest safety requirements, and therefore is suitable for particularly well being applied in the safe door.For the key that the locking function is provided with has been born the importing of adjusting simultaneously.Therefore the independent passage that on front and the back side of lock, is used to adjust the instrument of pivoted arm can be cancelled.Therefore also can in the adjustment state, lock be provided, adding key can be removed in the adjustment position.When the key that uses so far effectively, cooperate, adjustment process can only intactly realize at this.At this, wheel hub has been born otherwise the part of the function that a plurality of member must be carried out identically.This is at first not only relating to the adjustment of pivoted arm aspect the activation of adjustment, and is relating to new locking aspect the adjustment of lock to be achieved then.Wheel hub is at this approximate extendible portion that forms key, and open lock or lock pin a kind of drives and also at the element of construction of central authorities aspect the guiding mechanism of pivoted arm, it imitates key with acting on through wheel hub.Wheel hub has locking pin and adjusting pin to this place, front at it.Multifunctional component with the form of wheel hub is provided thus, and it also especially makes independent adjustment key become unnecessary in the future.Replace, the activation of adjustment is in reverse to actual rotation of opening direction through key and imports.

Through a kind of key that has bidentate is provided, according to key of the present invention because its compactedness has satisfied extra high safety requirements.It has the key level in both sides, wherein, the key level of relatively placing at a distance of farthest end each other at a distance of 9mm to 11.5mm.Key according to the present invention has satisfied stability criterion on the one hand at this, and builds on the other hand especially littlely, makes correspondingly, and for example the lock opening afterwards that is in of safety cabinet wall can correspondingly equally be constructed littlely and therefore more reliably.
