Description
Technical field
The present invention relates to lock core (lock cylinder), the plunger of lock core and the manufacture method of lock core
Background technology
Lock core is a kind of equipment that can be assembled in the latch mechanism (for example door latch mechanism) etc., makes it become latch mechanism by key control.Therefore, latch mechanism mainly contains an opening that forms within it, and the size and dimension of opening all is specific, makes it that standard lock core can be installed.Therefore lock core can be can't help latch mechanism manufacturer and made.
Lock core generally includes a rotating plunger that is arranged in the plug body.The body of lock core has a plurality of lock pins, these lock pins by the spring bias voltage to plunger.Described plunger has some holes, and corresponding plunger pin is housed in the hole.When standard key being inserted in the spoon groove (key-way), this key just with plunger pin to the predetermined distance of extrapolation, each plunger pin meshes with corresponding lock pin, thus overcome spring force also with lock pin to extrapolation.The shape of combined standard key is adjusted the length of each plunger pin, makes contact between each plunger pin and the corresponding lock pin along the perimeter alignment of plunger, and like this, plunger just can rotate in body.But when taking out key or inserting incorrect key, these contacts also do not line up, and the parts of one or more lock pins reach in the plunger, prevent the rotation of plunger effectively.
Lock core also comprises a driving member, and this driving member can be driven by plunger,, and with each member engagement of the latch mechanism that lock core is housed; Therefore, the rotation of plunger can be so that driving member be in locked condition or the situation that goes out of lock with each member of latch mechanism.
Lock core can be " single head " formula, and it comprises a plunger and a driving member, and lock core also can be " double end " formula, and this moment, it comprised two relative plungers and the driving member between these two plungers.The single head lock core only is used for the latch mechanism that need control with key from a direction one side of plate that latch mechanism is installed (for example from), and the double end lock core is used for the latch mechanism that need control with key from two rightabouts both sides of plate that latch mechanism is installed (for example from).
Plunger has the spoon groove of a given shape usually, and this shape has only manufacturer just to have.If standard key is inserted in spoon groove, then this key just should with this form fit.
Plunger is made by the solid bar of suitable material (for example brass) usually, forms pin-and-hole and spoon groove by mach method in plunger.Because the spoon groove is machined in plunger, so just require spoon groove to extend on the periphery of plunger.
When lock core installs in the latch mechanism, and latch mechanism is assembled on the plate or other is can fix on the parts of this latch mechanism the time, the user just can touch an end (it being defined as " front end " here) of lock core, specifically key can be inserted an end of plunger.
At assembly process, from front end plunger is inserted into the plug body, and plunger is maintained in the lock core, thereby prevent that plunger from oppositely deviating from from body by a lock ring or other member.Know yet attempt the intruder,, lock core is destroyed, and lock ring neither be avoided this destruction as long as firmly plunger is deviate from from lock core.Destroyed in case plunger is deviate from lock core, then lock bolt equipment just can not play effect usually.
International Patent Application WO 97/07309 has been introduced a kind of lock core that is made of several individual members, and this lock core can install to plunger the body of lock core from " rear end ", that is to say from that end relative with the front end of lock core plunger is installed to the body.
U.S. Pat 3702553 and 4472953 has been introduced several lock cores, particularly is applicable to the plunger of lock core, and described lock core is made of two independent components.Because two elements of plunger can be made respectively,, rather than form with the solid material machine so they can be made by die casting.In U.S. Pat 3702553, before two elements with plunger are inserted in the body of lock core, keep together with a cover these two elements earlier plunger.
Know also that in addition load onto one rotating " anti-drilling " dish near the lock core front end, this dish can rotate very neatly, thereby be difficult to even can not get out plunger that dish rotates with drill bit, thereby prevents that drill bit from taking out a large amount of metals from dish or plunger.
Summary of the invention
Purpose of the present invention aims to provide the plunger of a kind of improved lock core and this lock core, and this lock core is more than the advantage of known lock core.
According to the present invention, the lock core that is provided has a body, comprise rotating plunger in the body, the front end of this body can inject key in use, be formed with a spoon groove in the plunger, and also have at least one to be suitable for laying the hole of lock pin, plunger is made by at least two independent components, be formed with the part of spoon groove in each element, plunger be assembled into the body of lock core from an end relative with front end.
Because plunger made by at least two independent components, thus do not need to make spoon groove to extend to the periphery of plunger, but can allow the more close center of spoon groove.In addition, piston element can form in die casting, rather than be machined to a solid bar.In addition, do not need to make the element of plunger all to make, that is to say with identical materials, for element with pin-and-hole, can require with harder material, have the brass in mach hole above for example, and all the other elements form with aluminium or the die casting of zinc-base material.
From an end relative lock core is cooperated assembling with plunger with front end, plunger is reduced from the possibility of the front end mandatory dismantling of lock core, and the concrete benefit that lock core promptly can be installed from behind is: the attempt intruder is difficult to remove plunger from lock core by force.
Plug body comprises a lip shape equipment near being preferably in its front end, and the size of this lip shape equipment is less than the diameter of plunger.Therefore, lip shape equipment can reduce the possibility of by force plunger being removed from the front end of lock core.The material used owing to lip shape equipment is preferably identical with the material of body remainder, and best and these remainders formation one, so the resistance of Chai Chuing will be much larger than lock ring etc. by force, because itself installs lock rings etc. from front end, so under situation without permission, remove easily from front end.
This lock core preferably includes the rotatable disc of a shape picture " anti-drilling " dish; Usually this dish is arranged between lip shape equipment and the plunger, the diameter of dish is greater than the size of lip shape equipment.Therefore, an attendant advantages of assembling plunger from behind is: can assign an anti-drilling dish near front end, this anti-drilling dish forever is maintained by lip shape equipment substantially.This rotating dish has an opening, so just key can be inserted and enters by dish in the spoon groove of plunger.
In a preferred embodiment, the spoon groove shape of the opening shape of dish and plunger is not exclusively mated.According to this embodiment, attempt to prepare key, or the attempt intruder who attempts usefulness " duplicating " key, can not see the spoon groove shape of plunger by the opening of observing rotatable disc, also can make the spoon groove of plunger comprise at least one additional track, or unexistent other configuration in the opening of rotatable disc, thereby make non-standard key can pass through dish, but still can not be inserted in spoon groove.
Usually, the shape of spoon groove is not uniform along its whole length.So one or more features of spoon groove can only allow the specific keys with corresponding non-homogeneous shape be fitted in this path along spoon groove qualifying part path.In this way, though the attempt intruder know in the spoon groove shape of the front end of plunger, can not produce the copy key that can be fitted in the plunger.And in the design of prior art, because the spoon groove obtains through machine in the solid plunger, so the shape of spoon groove is uniformly along its whole length, but the inventor recognizes, this does not need to use the plunger that is made of an above independent component, thereby has improved security reliability.
Also described the plunger that can install in the above-mentioned lock core in addition, described plunger is made of a plurality of independent components.

The specific embodiment
The lock core 10 of prior art is " European plan " among Fig. 1.Lock core of the present invention (Fig. 5) also is " European plan ".But obviously the shape of lock core is to determine that by the latch mechanism that this lock core is housed therefore, the present invention can take different shapes as required.
Fig. 1 is the end view drawing of the lock core 10 seen from " front end 12 ".So front end 12 has the inlet of a spoon groove 14, this end is the end that the user can see in use, and the user injects key 16 (Fig. 2) at this.
Lock core comprises a rotating plunger 20, processes spoon groove 14 with known method in this plunger.The shape of plunger is selected by the special manufacturer of plunger usually, and has only this manufacturer just can have.The shape that it should be understood that key 16 must be consistent with the shape of spoon groove 14.Spoon groove 14 only is a kind of schematic diagram, it should be understood that the design of concrete shape is also unrestricted, that is to say, no matter be track 22 or the quantity and the position of notch 24, and the overall dimension of spoon groove is all unrestricted.
Those skilled in the art will be apparent from, and plunger 20 also has a plurality of pin (not shown), these pins and lock core with, specifically with the parts 34 of " European plan " lock core 10 with, spring biased lock pin (also not shown) engagement.。Should make such layout: in a single day standard key 16 is inserted in spoon groove 14, plunger 20 will rotate in plug body 30, so just can make plunger with lug 36 rotate, thereby drive driving member 40, and this driving member is with known method and the interaction of latch mechanism (not shown).When inserting, plunger is rotated when the taking-up lock or with non-standard key.
With known method plunger 20 is installed to the body 30 from front end.Though do not illustrate among the figure, should be provided with one and avoid the equipment of mounted plunger from the front end taking-up, this equipment can comprise a lock ring, panel or escutcheon, lock ring, panel or escutcheon fixed order arrive on the lock core (or latch mechanism), and cover the part of flared end 26.
Shown in Fig. 4 is " cross section " figure of double end lock core, and this lock core is by two relative lock core parts 42 (can be identical) formation, and connecting portion or bridge 44 are between these two lock cores parts.This lock core and International Patent Application WO 97/07309 describe some is similar.
It should be understood that this structure that comprises the assembly of independent sector, (when each parts 42 with when opening in 44 minutes, it is favourable touching the rear end, therefore plunger 20 can be inserted from the rear end can to touch the rear end 28 of body 30.And in " single-piece " embodiment of Fig. 1 and 3, can not insert this plunger) from the end adjacent with driving member 40.Yet in structure shown in Figure 4, plunger 20 is identical with plunger 20 shown in Figure 3, so plunger shown in Figure 4 is installed from front end.
Owing to the invention is characterized in from the rear end relative and insert plunger, so the present invention requires to be assembled into lock core with several individual members with front end.Therefore in the embodiment shown in fig. 5, lock core parts 46 are suitable for being fixed on a connecting portion or the bridge (do not illustrate among Fig. 5, but can referring to the bridge 44 of Fig. 4); Can be with any suitable method, for example any method of describing in the prior art document is fixed to lock core parts 46 on a connecting portion or the bridge.If necessary, again connecting portion or bridge are fixed on another lock core parts 46, so that form the double end lock core.
Lock core parts 46 comprise a through hole 50, and this through hole narrows down near front end 52; The part that particularly narrows down has formed a lip spare 54, and the size of lip spare is less than the diameter of plunger 56.Lip spare 54 is preferably circular, so just makes the diameter of the diameter of lip spare less than plunger 56.In this embodiment, lip spare 54 is continuous, but in further embodiments, lip spare is discontinuous, and it comprises one or more projections inwardly " finger ".
The lip spare that provides size littler than the diameter of plunger is provided, the design when only being in the centre position according to the spoon groove in the plunger is just effective; That is to say, a processing spoon groove in plunger, and in the design of the periphery that requires to make this spoon groove extend to plunger, lip spare can cover part spoon groove and prevent that key from inserting.Yet utilize the present invention, make plungers, just can make spoon groove leave periphery one segment distance of plunger, so lip spare 54 does not cover a spoon groove at all by two or more independent components.
It between lip spare 54 and plunger 56 a rotating dish 60.Form an opening 62 (also referring to Fig. 7) in this dish 60, so just make the key of given shape aim at and enter this hole (Fig. 6) with the spoon groove 64 in the plunger 56 by this hole.Yet should be clear and definite be, groove 62 is enough narrow makes it can prevent drill bit contact plunger 56 at the spoon of dish in 60, thereby even attempting the intruder tries hard to get out plunger, drill bit also can only contact disc 60, this dish is rotated, so also just prevented that drill bit from taking out more material effectively.
It should be noted that lip spare 54 is an one with the body of lock core parts 46; And anti-drilling dish itself is known, can not securely this dish be installed on the lock core in advance, that is to say, does not need independent cover plate or escutcheon, and cover plate or escutcheon itself can be taken off from front end by the attempt intruder.
Although near the lip spare 54 of the hole 50 of shown lock core parts 46 front end 52 all is continuous, but in further embodiments, can in the close hole of lip spare 54, increase a step, the step of this increase is used to be provided with anti-drilling dish, specifically this step prevents that plunger 56 from moving to and coiling the stage of fastening engagement, and this fastening engagement can make the effect of dish reduce.
Near the end in the hole 50 the end relative with free end 52 is drilled with screw thread, so this end can lay and have externally threaded axle bush 60, and this axle bush is used for plunger 56 is fixed on hole 50.Plunger 56 have one can by axle bush 60 and with the arm 58 of the driving member (not shown) of lock core engagement.
Be slightly less than hole 50 at the plunger shown in Fig. 5 56, can certainly understand, plunger is actually in hole 50 and is adjacent to, but can be slidingly fitted in the hole 50, that is to say, when inserting standard key 50, this plunger can rotate, but prevent gapped.
And in certain embodiments, can require to make the opening of dish 60 is simple rectangle, and key can pass through this opening, and another valuable additional reliable characteristic of the present invention is, coils different that 60 opening shape can be with spoon groove 64, and this feature is shown in Fig. 6 and 7.Therefore, a spoon groove 64 comprises two notch 66a, 66b (corresponding to each track (Fig. 9) on the standard key 68), and two tracks or projection 70a, 70b (being in the corresponding notch of key 68).Opening 62 on the dish 60 has corresponding notch and projection.But opening 62 also has another notch 72, and this notch is not in spoon groove 64.So attempt is by injecting (Master) key or obtain a key with the form fit of opening 62 of a handle " duplicating ", just want attempting the intruder and just key can not be inserted in spoon groove 64 by lock core.
Obviously, the feature in spoon groove 64, opening 62 can have any feature that can make key have the standard shape of spoon groove 64, thereby makes key both can pass through opening, can prevent that again some from can enter a spoon groove 64 by the key of opening 62.
Though in other less-than-ideal embodiment, the spoon groove in the plunger can be an ordinary construction, also can be the square-section, without any track or notch.But anti-drilling dish can have some tracks and notch, and this anti-drilling dish can make the lock core of making conform to the key shape of special manufacturer.This embodiment does not have above-mentioned added security energy, but simple in structure, and the design of plunger is general.
Fig. 6 also shows by two independent components 74 and 76 plungers that form 56, in this embodiment, and half that these two elements are plunger 56 substantially.Preferably die casting of element 74 and 76, each includes a part of pin-and-hole (not shown), and in the plunger that assembles, described plunger pin is supported in these holes, and when standard key is not in the spoon groove, the part of each lock pin can also be laid in the hole.
Fig. 8 and 9 shows another preferred structure of the present invention.Therefore and since the spoon groove a part be formed in each element 74,76 of plunger, so the spoon groove need not be uniform along the shape of its whole length.In an illustrated embodiment, notch 22b terminates in the front of the end 78 of spoon groove 64.So the respective rail 80 of standard key 68 also should terminate in the front of key end, thereby key 68 is inserted in spoon groove fully.In addition, except the end of spoon groove, the attempt intruder can not see a spoon groove at the front end of plunger, do not know the groove of determining in spoon groove 64 at all, unless key changes along its length neither one or a plurality of architectural feature,, the attempt intruder can not be inserted into fully in spoon groove otherwise finding the key that mates with the spoon groove shape of plunger front end.
This architectural feature can make lock core manufacturer more safely control duplicating of key, key cutting machine can only be processed (Fig. 9) to the limit 82 in this key 68 usually, but can not process track 80, therefore, lock core manufacturer can control the supply of the key blank with ideal track shape better, for example the lock core with a kind of given shape can be fed to part area, be fed to another part area and will have difform lock core, the key blank in each several part area can not be exchanged.
Certainly, also can change shape at more than one position along the length of spoon groove, but in order to prevent that non-standard key from inserting, change of shape just must increase material in the end of spoon groove, this is because can not prevent the insertion of non-standard key after the material taking-up.Another proper site that increases material is near the lower end of spoon groove 64, for example in the position shown in Fig. 8 dotted line.
In the embodiment shown in fig. 10, plunger 86 is made of three independent components, and in this embodiment, the material of these elements is incomplete same.Therefore, because the element 88 of two more complicated and 90 their common overwhelming majority that form the spoon groove so these two elements are made with die casting, for example form with aluminium or the die casting of zinc-base material.Element 94 has the part of spoon groove, but obviously is the element that is formed with pin-and-hole; In order to guarantee that better pin works reliably, be preferably in draw-bore on the hard material, brass for example, for this reason, element among this embodiment 94 is made of brass.It should be noted that element 94 also comprises the part of spoon groove, but in further embodiments, can change the relation between each element, make the inside be formed with the element of pin-and-hole without any the spoon groove.
Figure 11 represents another by the plunger 96 that four elements constitute, and each element comprises the part of spoon groove.
Obviously, also can provide other embodiment, can also provide to have two the embodiment that the structure of three or four elements is different as required with four above elements.In addition, the spoon groove is the ordinary rectangular shape not necessarily, for example can be " L " shape with track and/or groove usually, and is "T"-shaped, " U " shape, and circle or polygon, thus make a spoon groove obtain needed shape (special manufacturer); For required given shape, can select the quantity of element and their layout.
Though the specific design of plunger and constitute plunger element quantity how, plunger can be assembled at first in the sleeve (not shown), in being assembled into body before, this sleeve keeps together each element.In addition, can reserve the size of sleeve, so that be mounted in the hole of body, like this, sleeve is exactly a permanent member of the lock core that assembles, and sleeve has each the pin-and-hole aligned pin with plunger, and is fixed and rotates with plunger.
In the embodiment of sleeve as a permanent member of the lock core that assembles, the corresponding periphery of the interior shape of sleeve and plunger can be circular, and like this, sleeve and plunger remain on a specific angular relationship, and plunger can not rotate in sleeve.The interior shape of sleeve for example can be a hexagon, quadrangle or triangle, and the periphery of plunger also is an analogous shape.In certain embodiments, the periphery of plunger can be a polygon, and the number on polygonal limit is complementary with the parts number that constitutes plunger.
In addition, the outer shape of plunger and the interior shape of sleeve can be circular usually, but sleeve has bead of inwardly stretching out etc., bead can be arranged in the respective slot of an element of plunger, make an element of plunger can utilize bead to keep the location with respect to sleeve, all the other elements keep locating by their engagements with this element.
