Abstract

A safety lock comprises a lock-bolt element, which can be controlled by means of a cylinder lock. The actuation of the latter by means of a key sets in rotation a radially extending control member (13), which is received in a radial slit of a ring gear (10) mounted so that it can turn coaxially with respect to the rotor of the cylinder lock. The rotation of the control member (13) impressed by the key then brings about a rotation of the ring gear (10). A mechanical transmission (7), including at least one gear (9) meshing with the ring gear (10), converts the rotation of the ring gear (10) into a rectilinear sliding of the lock bolt (3). In any point of the mechanical transmission (7) a coupling is provided between a driven member and a driving member that affords said members the possibility of a limited relative movement. Consequently, the movement of said driving member is transmitted to the driven member only after said members have reached one of their two relative end positions.

Description

Safety lock

Technical field

The present invention relates to the field of security lock arrangement.

Background technology

This kind safety lock comprises:

A stiff case;

A bolt element, be installed into can be in housing an enable possition and a fastening position between slide;

A cylinder lock has a stator and a rotor that is used for rotating a control member that radially extends that is fixed on the housing;

A rim gear wheel, being installed into can be in housing and the rotor coaxial line rotation of this cylinder lock, and has a radial slot to be engaged by the radially control member of this cylinder lock, thus when this cylinder lock during by a key unlocking, this rim gear wheel is rotated by said radially control member; And

A mechanical transmission mechanism comprises at least one and said rim gear wheel meshed gears, so that the straight line that changes rotatablely moving of said rim gear wheel into said bolt element moves.

A kind of device of above-mentioned pattern is for example once shown in French Patent (FRP) FR270732 number.

The ordinary skill of invading this lock is that this cylinder lock is got from this device.Because fixing of this cylinder lock just relies on a pin that is inserted in this cylinder lock body in this device.The drag of this pin is limited, not only because cylinder lock all has standard size cause pins nail dimension to be difficult to remarkable increase, and the most important thing is because this pinning mainly bears shear stress.

In newer device; In order to make inaccessible cylinder lock in device case have safety largely; Once adopted such method; Promptly when this lock not by key unlocking but when resting on complete opening or closing state, let the radially control member of this cylinder lock from this cylinder lock body, stretch out to side, block said lock body like this it can not be drawn out of in this housing.

But under this lock complete opening or the dormant state of closing with this radially control member like this layout other problem can take place; This is because when this cylinder lock is installed in the housing; Though this radially control member can be from this cylinder lock side to a side or opposite side indistinguishably stretch out, make the rim gear wheel that will inevitably spur it and engage like this.This means according to this radially the control member direction of the stretching out mechanical transmission mechanism of following this rim gear wheel and driving this bolt element in the process that drives, will be on the leading or position that lags behind.This lock just lacks accurate and unique adjusting benchmark like this, and its operation will be more not smooth; Will be concerning the user inconvenient, he must according to oneself feel estimate that this lock is complete opening or cuts out fully.

Summary of the invention

The present invention is exactly these shortcomings that will overcome existing apparatus.

In order to reach said purpose, target of the present invention is a kind of security lock arrangement, comprising:

A stiff case (2);

A bolt element (3), be installed into can be in housing (2) an enable possition and a fastening position between slide;

A cylinder lock has a stator and a rotor (12) that is used for rotating a control member (13) that radially extends that is fixed on the housing (2);

A rim gear wheel (10); Being installed into can be in housing (2) and the rotor coaxial line rotation of this cylinder lock; And a radial slot (10a) arranged; Said otch is engaged by the radially control member (13) of this cylinder lock, thereby when this cylinder lock during by a key unlocking, this rim gear wheel is rotated by said radially control member (13); And

A mechanical transmission mechanism (7) comprises at least one and said rim gear wheel (10) meshed gears (9), so that the straight line that changes rotatablely moving of said rim gear wheel (10) into said bolt element (3) moves.

Being characterized as of said device in any position along above-mentioned mechanical transmission mechanism (7); Between as the said bolt element of driven member and the cylinder lock as actuator, the mechanical transmission mechanism as coupling is set, the two relative to each other provides the possibility of restricted slip and restricted rotation respectively to this coupling to said driven member and actuator.

Because said characteristic; Particularly owing to promptly on any point in machine driving path between cylinder lock and the locking bolt, might do limited relative motion between actuator and the driven member, the motion of said actuator is designed so only just is passed on the said driven member it after said these parts arrive the relative position of process terminal points.The benefit of doing like this is that key can drive on same angle position and makes locking bolt begin to move and can whether the radially control member that stretch out from a side or the opposite side of this cylinder lock body be housed regardless of this cylinder lock.Thereby can how to install regardless of this cylinder lock, always the opening and closing of this device can be accurately and are reliable.

The specific embodiment

Consult Fig. 1 and 2, security lock arrangement 1 has a housing 2, has a bolt element 3 between an enable possition and a fastening position, to slide in it.This bolt element 3 is made up of like some cylindrical rod 3a that are fixed on the plate 3b a plurality of pinning elements.This plate 3b is provided with guide groove 5 and an otch that is shaped to limit a tusk 6.The motion of this plate 3b is by a mechanical transmission mechanism 7 controls.Said mechanical transmission mechanism 7 is made up of a disk 8 and a gear 9 (Fig. 4 a, 4b).On a surface of this disk 8, fix two axial pin 8a (in Fig. 4 a, 4b invisible but shown in Fig. 3), be used for tusk 6 engagements (Fig. 3) with this plate 3b.This disk 8 also has a protuberance 8b, and (Fig. 4 is coupling a) to design the centre bore 9b that is used for this gear 9.It is circular that this protuberance 8b is essentially, and the side 8b ' on a plane is arranged.This hole 9b has a corresponding circle; A circular part is broken off by the side on two planes; These two side planes are set up at angle and form the butting surface that cooperates with this surface 8b ' mutually, thereby in the relative rotation of this disk 8 and this gear 9, limit the position at two ends.In fact this being arranged in be exactly to make the rounded portions of this hole 9b that a big angular range than the part 8b of this disk 8 arranged.So just between this disk 8 and this gear 9, cause free gap (mean and possibly relatively rotate), its value equals the poor of said this two angular range.

This gear 9 and a rim gear wheel 10 engagements, the base of this rim gear wheel is fabricated on the boss 11 that is fixed on this security lock arrangement 1 housing 2.This rim gear wheel 10 has a radial slot 10a, and its width equals the thickness of this cylinder lock body bottom (invisible among the figure).This rim gear wheel 10 is around this cylinder lock; And this cylinder lock has a stator (not shown) and a rotor (also not shown) that is fixed on this housing 2 according to traditional technology; This rotor can rotate with a key (not shown); Thereby can make part 12 rotation, have one radially control member 13 stretch out from this part.

This radially control member 13 be set in the otch 10a of this rim gear wheel 10; And it is as visible in Fig. 2; Radially between the sidewall of control member 13 and this otch 10a the free gap can be arranged at this, this free gap equals width poor of this otch 10a and this radial elements 13.

When this cylinder lock during by key unlocking, this radial elements 13 just supports on the sidewall that this rim gear wheel 10 forms otch 10a and promotes this rim gear wheel rotation.

The stator of this cylinder lock is fixed in the housing 2 through the pin 14 of laterally inserted this cylinder lock body bottom.This pin 14 is carried by a plate 15, this plate can be this housing 2 in this cylinder lock body is sold inside the country follows closely bonding station of 14 and one and be disengaged between the position and slide.This plate 15 is by the cross bar that can operate from the outside 16 controls.Because the encapsulation of said this cylinder lock in this locking device is considered to abundant inadequately from purpose of safety; Therefore under the state that this device stops; On complete opening or the position closed, with this radially control member 13 be provided with like this it stretched out from the side of this cylinder lock body, when being installed in this cylinder lock in this housing; This radially control member 13 temporarily remained on middle position; Make key its neutral position rotation relatively, rotate back into said neutral position again, this part 13 is stretched out from this cylinder lock body along side direction.But a said side or the opposite side that stretches out the indifference status at this lock body, this will see when this lock body is originally in being inserted into this device from which end to begin.

Therefore as stated, when this cylinder lock is installed in the housing and this key when being rotated back into its neutral position, this part 13 on this lock body, accomplish once little swing (in a side or at opposite side, as stated, look this lock body under installment state orientation and decide).Said little swing is passed on this rim gear wheel 10, makes it or is driving on the direction of locking bolt or rotation in the opposite direction.Obviously same little swing is delivered on this gear 9 by this rim gear wheel 10.

For example consult Fig. 8, suppose that wherein this cylinder lock is once by such installation, promptly at the neutral position of key, this part 13 is to stretch out (like the figure finding) to the left side of its middle position.This means that this part 13 is once accomplished a little swing (like the figure finding) in clockwise direction when this cylinder lock is installed, and this rim gear wheel 10 is driven into position shown in Figure 8, this part 13 contacts (again like the figure finding) with the left-hand side of this otch 10a in this position.When using key to close this lock like figure finding need with this part by counterclockwise to rotation.Therefore this part 13 can not order about this rim gear wheel 10 rotations before the right-hand side with this otch 10a contacts.Be rotated further this key from the moment of said contact, this part 13 will order about this rim gear wheel 10 rotations, and this rim gear wheel makes gear 9 correspondingly rotate again.But the rotation of this gear 9 can not be passed on the disk 8 that is loaded with this locking bolt tusk 6 engages pin 8a immediately, is just transmitted in the time of will arriving two terrace 8b ' and 9b ' always and contact with each other.In case this key rotates to above-mentioned position contacting taking place, further rotates this key and just can make this locking bolt displacement.

If not like this; This cylinder lock is other a kind of situation when being mounted; Promptly under dormant state; This part 13 is to stretch out (like the figure finding) to the right as shown in Fig. 6, and the little swing accomplished of this part 13 when mounted is to make this rim gear wheel 10 counterclockwise to doing for the first time initial rotation that is to say.Thereby said rotation can make gear 9 do corresponding rotation and make two terrace 8b ', 9b ' contact.Begin to rotate this key from said state and just can make this locking bolt displacement immediately.This shows, no matter this part 13 is stretched to a left side (Fig. 8) when mounted and still stretches to the right side (Fig. 6), always the effective exercise of this locking bolt can begin from the same position that drives key.

When two of this disk 8 pin 8a constitute the tooth in the profile of tooth thing 6 of this plate 3b in groove, promptly when they when the direction of motion of bolt element 3 is alignd, this locking device is to be in a safe condition when stopping.If there is any bump to be applied on the cylindrical rod 3a of this lock, owing to there is the free gap, this disk 8 can be rotated a position, in this position one of them pin 8a can leave former in the position, just can make the process reverse of closing this security lock arrangement like this.As visible from Fig. 5; Be provided with a lever 17 at the back at said cylindrical rod; Upward (Fig. 4 a) after it is promoted by an elastic body 18, just can to support to the surperficial flat region 8c of this disk side; Can cooperate with the terrace of this lever 17 by this flat region of design, make the disk that is in the opening and closing state turn back to a position, these two pin 8a are in safe condition in this position.

Said like above; Begin from the dormant state of this device complete opening shown in Figure 8, wherein this radial elements 13 is stretched to the left side of this cylinder lock body 12, through the driving of key; This radial elements 13 to being rotated, is set in closed condition with this device counterclockwise.Null process is that this radial elements 13 is taken on the right hand wall that is bearing in these rim gear wheel 10 radial slots 11 for the first time; Then this radial elements 13 promotes rim gear wheel 10; This rim gear wheel is driven wheel 9 again; And being connected owing to exist the free gap between this gear 9 and the disk 8 need be carried out null process second time this disk of driving really.When the second time, null process stopped, this radial elements 13 arrived position shown in Figure 8.As stated,, make its this radial elements 13 when stopping just be in position shown in Figure 6, this device is closed and can not need any initial null process if this cylinder lock 12 is installed like this.

In situation shown in Figure 6; The terrace 9b ' of this gear 9 centre bore 9b contacts with the terrace 8b ' of this disk 8 central part 8b; Therefore this radial elements 13 subsequently counterclockwise to rotation this disk 8 will be rotated; Move thereby make in the tusk 6 of pin 8a on this bolt element 3 plate 3b of disk 8, so just drive these bolt element 3 straight lines and move until close fully.

In security lock arrangement shown in Figure 9, wheel chain is to be on the centre position of driving process.Radially the effect of control member 13 is as a tooth of this rim gear wheel 10 can be noted that this, and in the process that drives, the transmission of wheel chain can be carried out glibly continuously.

Above-mentioned these radially are not enough to tooth to this gear 9 and produce and disturb in the free gap between the control member 13 at the sidewall of this otch 10a and this so possibly be.

Obviously can know from above-mentioned explanation, according to being characterized as of lock of the present invention, can provide accurately, reliably and easily operate, and not cause complicated especially structure to the user.Particularly the solution with known is different, can use the state gear all the same with size of tooth according to lock of the present invention.Another of preferred embodiment shown in this paper is favourable is characterized as the mechanical transmission mechanism that moves that rotation with rim gear wheel 10 is transformed into locking bolt and only has an independent gear 9 and pin 8a a pair of and tusk 6 compounding practices.

Certainly, under the condition that does not depart from the principle of the invention, structure detail and embodiment can very much not be same as pure conduct demonstration here and explain and illustrated content, still belong in the scope of the present invention but do like this.
