Figure 18 shows the lateral view of (also being to amplify) lock pin and its finger tip (from its free end).

Fig. 1 and key 1 shown in Figure 3 have the longitudinal axis A of an insertion, and can inject in the lock shown in Figure 3.Key 1 has a front end 2 and a rear end 3, thus rear end 3 be connected in one hold the part or head 3 constitute a complete key.

As shown in Figure 2, key 1 is normally flat, and the side 4 and 5 that is roughly the plane is arranged.There is a small stair 6 side 4 on the left side among Fig. 2, and there is a cannelure 7 side 5 on the right among Fig. 2, thereby its upper side wall 8 tilts outside key, and its lower wall 9 is located in the central plane P that is approximately perpendicular to key.And lower limb surface 10 is the curved surface shape a little.The transverse shape of visible key 1 and the key 11 of lock match from Fig. 1,2 and 3.Like this, key 11 roughly has a rectangular cross section, and by a left side wall 12, a right side wall 14, straight wall 16 in short top and bottom, there is curved wall 17 to limit slightly, left side wall 12 has the step 6 of a step 13 corresponding to key, and right side wall 14 has a vertical protrusion 15 corresponding with the groove 7 of key, and the lower limb surface 10 of curved wall 17 corresponding to key arranged slightly.

Lock 18 is the rotor pin type, comprises that 19, one of cylindrical shells are rotatably installed in shell 19 interior key plugs 20 and see Fig. 5 and 6 so that a shear line 21(to be provided between shell 19 and plug 20).Key 11 is extended to hold key 1 in key plug 20 with the direction of the axis of rotation that is parallel to key plug 20.

Lock 18 also comprises two row's lock pins 22,23, and they are positioned at two planes that are parallel to each other, and comprises that the row 22 of six lock pin 22a-22f roughly is positioned at the central plane of key 11.Each lock pin 22a-22f can do to raise and rotatablely move in the cylindrical hole 24a-24f separately on key plug 20, the top of each this Kong Douyu key 11 communicates, so the lower end chisel-shaped of each lock pin 22a-22f part all can mesh with V-arrangement, the slant cutting edge of the upper rim of key 1 when key inserts.A corresponding row 25 who comprises pushing pin 25a-25f can be moved back and forth by the guiding of the cylindrical hole 26a-26f on cylindrical shell 19, they are pushed downwards under the effect that promotes spring 27a-27f, thereby apply a downward power to the position of rotation of each lock pin 22a-22f(at key plug shown in Figure 3 20, hole 24a-24f aligns with hole 26a-26f) or to the outer cylinder surface of key plug 20 (when it is opened and rotates).

For making the shear line 21 between shell 19 and the plug 20 complete, the key with top edge of a suitable otch must be inserted in the key, is positioned at such position so that each lock pin 22a-22f raises, and promptly the upper surface of lock pin is concordant with shear line 21.And, each lock pin 22a-22f must be rotated (by means of the slant cutting edge at edge on the key), so that the vertical notch 28a-28f on its periphery is positioned at separately is relative longer with the rib 29a-29f(separately of barrier member or side lever 29) positions aligning (seeing Figure 10 and 11), side lever 29 slidably with key plug 20 on 30 engagements of lateral opening groove.Side lever 29 is forced into the locked position (see figure 5) under the effect of spring 31, and the corresponding cam groove 32 in this position on the inner cylinder face of radially outward outstanding cam portion 29m and shell 19 meshes.Yet when all rib 29a-29f alignd with the notch 28a-28f of lock pin 22a-22f, side lever was allowed to revolt the effect of spring 31 and to intrinsic displacement, when applying a rotation torque between plug 20 and shell 19, plug 20 just can be rotated thereupon.

Described so far locking mechanism can be from above-mentioned patent US-A-3, and 499,302(and Reissue 30198-oliver et al) learn.Yet lock 18 also comprises a further locking mechanism, and it comprises above-mentioned lock pin row 23.

This row who comprises five lock pin 23a-23e laterally is offset (to the right of Fig. 3 and Fig. 6), but is parallel to row 22.Each lock pin 23a-23e is limited in interior corresponding cylinder hole of key plug or the hole 33a-33e (also seeing Fig. 4 and 6) separately fully, and hole 33a-33e uniformly-spaced arranges.

Each lock pin 23a-23e is being pushed downwards (as shown in drawings) separately under the spring 34a-34e effect, spring is between the top of the bottom of each hole 33a-33e and each lock pin 23a-23e.Shown in Fig. 7,8 and 9, spring partly is contained in one by hole 35(Fig. 8) in the last pit that forms, with guiding therein, and around a center pin member 36 as the drill bit protection.Each lock pin 23a-23e comprises a barrel portion 23ab-23eb, it can be in the Kong Zhongzuo rotation separately and the motion that raises, also comprise a finger tip 23af-23ef, each is laterally outstanding by corresponding opening 37a-37e since the bottom of barrel portion, and opening 37a-37e is on the wall of separately hole 33a-33e and the key plug between the key 11.Like this, as shown in Figure 6, the part of finger tip (23bf) extends near the protrusion 15 the key 11.

Will further explain as following, engagement between key 1 and the finger tip 23af-23ef will make that each finger tip is separately around the longitudinal axis B(of barrel portion 23ab-23eb Fig. 7) rotation, and when when elongated wavy coding decorative pattern 38 contacts by displacement up and down, 38 processing of coding decorative pattern are on the lower wall 9 of the groove 7 of key.When finger tip rotation with when moving back and forth, the corresponding barrel portion 23ab-23eb of the lock pin 23a-23e motion that is rotated and raises.When key 1 is inserted into key 11,, corresponding spring 34a-34f guarantees that finger tip 23a-23e contacts coding decorative pattern 38 continuously thereby promoting lock pin 23a-23e downwards.

In order to guarantee this rotation and the reciprocating motion of finger tip 23a-23e, the vertical direction size of opening 37a-37e between hole 33a-33e and key 11 is greater than the height (along the direction that is parallel to the longitudinal axis B among Fig. 7) of finger tip, and the width of opening 37a-37e is enough to allow finger tip to be as the criterion with the longitudinal axis direction perpendicular to key 11 to rotate about 15 ° (in these specific embodiments) to all directions, thus preferably oblique the facing key 11 and provide a good supporting surface that limits of the sidewall of opening at each rotation terminal location of finger tip separately.When finger tip was moved back and forth up and down, these sidewalls had also guaranteed level and smooth slip engagement.For a kind of so level and smooth slip engagement is provided, the sidewall of each opening preferably extends along the direction of the Cylinder that is parallel to each lock pin longitudinal axis B partly, and with respect to the side profile of corresponding finger tip a roughly complementary shape is arranged.Like this, between them, guarantee linear contact at least, thereby reduce friction and wear and tear.

From Fig. 7,9 and 12 as seen, at least one position-scheduled coding dimple is all arranged on the cylindrical outer surface of the barrel portion 23ab-23eb of each lock pin, the size of described coding dimple can be held corresponding in one group of relatively short rib, and relatively short rib is from outstanding between the above-mentioned long rib 29a-29f of side lever 29.

In Fig. 7 and Fig. 9, the coding dimple is to be made of a cylindrical hole 39a, and corresponding rib is straight pin 40 " a that can cooperate with 39a.When lock pin 23a-23e is placed in predetermined rising and position of rotation, " a's straight pin 40 will align with cylindrical hole 39a; and allow laterally inwardly displacement of side lever; make side lever enter position in the groove 30 of plug 20, so just opened lock (also aliging with the notch 28a-28f of lock pin 22a-22f with duration rib 29a-29f).

Figure 12 illustrates one and improve embodiment, wherein the dimple on the face of cylinder of lock pin 23 ' a is made of elongated slot a 39 ' a, and side lever 29 ' on corresponding short rib be to constitute (it has the cross section that can match with the shape of elongated slot 39 ' a that is generally rectangle) by billet a 40 ' a.Under any circumstance, should design dimple and rib like this, promptly when rib entered dimple, lock pin will remain on the rising and the position of rotation of good qualification.

Figure 12 a shows lock pin dimple and respective side bars 29 " another improve embodiment.Be not an independent hole or groove, but two dimple 39 " ax and 39 " ay are independently arranged, they are positioned at lock pin 23 " on the face of cylinder of a and be spaced from each other a distance, has ligule part 39 " az between them.Each this dimple 39 " ax, 39 " thus ay forms a roughly structure of C shape by the processing of cutter, as direction finding along the cutter shaft (not shown).Middle part ligule part 39 " size of az can with parallelepiped groove 29 " a, 29 " among the b etc. corresponding one (29 " a) match (each lock pin is maintained at predetermined rising and position of rotation simultaneously), the parallelepiped groove is that processing is at side lever 29 " on.

This embodiment with advantage be that vertical inward flange of side lever will contact with the skewed surface of C shape dimple, like this just in case spring 31(Fig. 3) in the time of can not being enough to side lever withdrawn from it enters the position of groove 30 of key plug (because a variety of causes), draw key to make gently to make on the lock pin 23 " rising such as a has a lateral forces like this in side lever 29 " it pushed outwardsly to go out (this is by means of the contact between following vertical inward flange of dimple skewed surface and side lever).For this purpose, the dimple soffit should be oblique at least, and upper surface can be a level.Can certainly make vertical inward flange of side lever null circle be arranged slightly to reduce wear.

Certainly, even in this embodiment, side lever 29 " also can have relatively long rib (being similar to the 29a-29e among Figure 11), be used for meshing with the additional row of lock pin (being similar to lock pin 22a-22f).

For the key system of standard is provided, each lock pin also can have at least one other dimple 39aa, and 39 ' aa is shown in Fig. 7,9 and 12 chain-dotted line.

The coding decorative pattern 38 of key 1 is described referring now to Fig. 1,2,13,14,15,16,17 and 18.

Be substantially equal to half of key thickness along the degree of depth of the longitudinal axis A of key 1 groove 7 that 3 forward end 2 are extended from the rear end, this will find out from Fig. 2 and 17.The degree of depth of groove 7 makes the free end of each finger tip 23af-23ef always keep certain distance to the diapire of groove.Under any circumstance, the diapire of groove 7 can not hinder the rotation of finger tip.And, the rotation of finger tip and reciprocating motion are just caused by the bottom of finger tip and the engagement between the coding decorative pattern 38, this engagement is guaranteed that by the effect of spring 34a-34e coding decorative pattern 38 is that processing is on the lower wall 9 of groove 7 (seeing Figure 17).Like this, the upper side wall 8 of the continual inclination of groove 7 just can not produce this engagement with finger tip.

Coding decorative pattern 38 is finally by one one side, wavy spigot surface constitutes, spigot surface comprises a series of recesses 40,41,42,43,44, and a series of connection chamfered portion 40a, 40b, 41a, 41b, 42a, 42b, 43a, 43b, 44a, 44b, these inclined-planes extend between the remainder of each recess and groove sidewall 9, thereby between every pair of adjacent chamfered portion, stayed the top 46 that is roughly the plane, 47,48,49 and 50, also has another one chamfered portion 45a, it arrives the lower limb 10 that closes on its front end 2 on the key always, thereby provide an inlet spigot surface, in the time of in key 1 is inserted into key 11, this inlet spigot surface allows each finger tip 23af-23ef to enter engagement with wavy coding decorative pattern.

Thereby the degree of depth of the recess that coding decorative pattern 38 be provided of processing on the lower wall 9 of groove 7 is substantially equal to the degree of depth of groove 7 own.Like this, the inside 51,52,53,54,55,56 of these recesses has formed the extension on the plane of groove 7 diapires, and can not hinder finger tip 23af-23ef.

Each recess 40,41,42,43,44 all has a bottom surface portions (41c among Figure 15 and 16,42c and 44c), this bottom surface portions is normally leg-of-mutton, thereby and be directed and face up, this bottom surface portions is approximately perpendicular to the central plane P of key and extends (see figure 2), and the longitudinal axis A(that is parallel to key sees Figure 13).Bottom surface portions triangular shaped can be in the key insertion process and key the supporting of each finger tip of a good qualification is provided when arriving final insertion position in key, in the key insertion process, when the position of one of each recess of key lock pin 23a-23e by lock, finger tip will rotate to another terminal location from a rotation terminal location, and when key arrives final insertion position in key, finger tip will be directed to various predetermined position of rotation, as quadrature lateral attitude or rotation terminal location, at the rotation terminal location, finger tip is directed to obliquely front-end and back-end towards key (among Fig. 9 relatively three chain-dotted lines).

For a kind of like this supporting is provided, being generally leg-of-mutton bottom surface portions (41c, 42c and 44c) all has the sidewall sections of connection, as in Figure 15 and 16 digital 41d, 42d and 44d indicated, these sidewall sections obliquely extend with respect to the longitudinal axis A of key.

Preferably bottom surface portions 41c etc. with is connected connection smoothly such as sidewall sections 41d, junction curvature is roughly corresponding to the curved surface of a low convexity, as the cylindrical surface part 57 corresponding to finger tip.And the incline direction of each sidewall sections 41d etc. should correspond essentially to the terminal location direction of rotation of finger tip, thereby provides a line contact or face contact between finger tip and corresponding sidewall sections.

Shown in Figure 15 (on the right), at least one can have a cylindric recessed 42c of part among the bottom surface portions 42c, should extend perpendicular to the longitudinal axis A of key by recessed cylinder axis, thereby a good supporting that limits is provided for the finger tip that is in the respective orthogonal lateral attitude.

As shown in figure 16, might by end mill(ing) cutter draw expansion in the middle of bottom surface portions 44c, form one shallow, the transverse uplift 44f at center, and help making.

Be used for connecting the chamfered portion 40a of sidewall sections 41d etc., b, 41a, b, 42a, b, 43a, b, 44a, b and inlet chamfered portion 45a are parallel to the incline direction of sidewall sections 41d-44d usually, and so just formed the inclined plane outside key, like this, the lower curved face part 57 of finger tip just with line contiguously with chamfered portion engagement, thereby when these chamfered portions of wavy coding decorative pattern slide, reduced to be in contact with one another surperficial wearing and tearing when finger tip.For a kind of like this line contact is provided, only the outside of chamfered portion is the just enough of inclination.And a kind ofly so partly tilt and can extend at recess, this is because the inside of its bottom surface and sidewall sections will provide enough supportings.

The size design of recess comes to match with the size and the geometry of finger tip, thereby locatees and support finger tip effectively on the predetermined position of rotation of finger tip.

Shown in the most preferred embodiment, each finger tip 23af-23ef is positioned near the lower end of barrel portion 23ab-23eb, and roughly along the whole of barrel portion the top width degree is laterally extended, and outwards protrudes from cylinder.Each finger tip all has the section that is roughly rectangle of a band convex surface, as the columned soffit of part, the curvature of this cylindric soffit is roughly corresponding to the area supported part of recess of coding decorative pattern, and each finger tip also has plane, the side surface 58,59 that is parallel to each other.The inner of finger tip, an end that promptly closes on barrel portion is a convex surface, thereby with cylindrical shell 9 a level and smooth (see figure 6) that contacts is arranged.The free end surface of finger tip does not contact with any part of key and lock, and its shape is unimportant.But there is shown upper surface 60 ' (Fig. 9,17 and 18) that inclination is arranged slightly, do not contact with the updip skew wall 8 of on the key groove 7 to guarantee finger tip.

The surface 57,58 that should be noted that finger tip contacts with the different parts of key and lock with 59.Like this, the central cylindrical part 57 of soffit 57 ' only contacts with the bottom surface portions of the recess 40-44 of coding decorative pattern, and the sloping portion that is roughly the plane 57 of soffit 57 " lean against chamfered portion 40a; b-45a is last and move, and flat side surface 58,59 leans against and slide along the sidewall of opening 37a-37e.Like this, even at side surface 58,59 and planar section 57 " wearing and tearing are to a certain degree arranged, and this wearing and tearing will can not influence the location of finger tip in recess, this be since this location only with bottom cylindrical surface part 57 ' relevant.

In the scope of claim 1, can carry out many improvement to this lock.Like this, although deciding mechanism, twin-lock can provide more substantial coded combination, but also can imagine only with row's lock pin, certainly, the quantity of lock pin can change among one row, it also is possible that a lock pin is only arranged, especially if with some other locking mechanism altogether the time.

Can use two row's lock pins according to the present invention, one row be arranged as each side of key.

The longitudinal axis of lock pin also can be at a slight tilt with respect to the central plane of key.Yet finger tip preferably is directed with the described central plane perpendicular to key, if the coding decorative pattern is that being positioned on the groove of key side should be so at least.But the coding decorative pattern also can be positioned on the step or grid surface of key side, even can be on two longitudinal edges of key.

The quantity of the possible position of rotation of key can change, and as two, three, four or five all is practicable, as if two or three position of rotation are better certainly.

Thereby lock pin should be kept Continuous Contact by displacement and on the key coding decorative pattern.Yet, can apply this displacement force with magnetic element without spring.

As if rotatable lock pin can cooperate with corresponding side lever respectively, but a common side lever is actual.
