Description of drawings
Now, will be by way of example, describe the present invention with reference to the accompanying drawings.In these accompanying drawings:
Fig. 1 be one according to the present invention the longitudinal side sectional drawing of cylinder lock, this cylinder lock has insertion key wherein; And
Fig. 2 is the sectional drawing of the 2-2 along the line of Fig. 1.
The specific embodiment
What Fig. 1 described is the general type of pin brake bars cylinder lock, comprises an individuality 10, and body 10 has an annulus profile hole 11 of passing wherein.Rotatably being fixed in the hole 11 is a connector or cylinder 12, at connector or cylinder 12 front ends, has the bead of an increase, to limit its insertion to hole 11.At its opposite end, form cylinder, this cylinder has and is used for device (not shown in the drawings) that it is remained in body, also has a connecting rod that leans out from the end of cylinder in normal mode etc., to operate a latch or equivalent.
In " locked " position of cylinder, arrange in a line with corresponding vertical radial hole 15 separately in body in these holes 14, and hole 15 directly is communicated with hole 14, as shown in fig. 1.By along the length direction of the cylinder pin repeatedly and the system of spring, can guarantee that usually cylinder can not rotate in body.Fig. 1 has illustrated the hole 14 of arranging in a line and each group of 15; The pin of two parts, the pin 16 that in cylinder, holds and the form of a relevant drive pin 17; And a relevant biasing spiral compression spring 18 in the individuality.One end of spring leans against on the drive pin, and its other end engages with a connector that closes closed pore 15.
Be familiar with as people, the biasing of spring reaches such degree: when not having key in the key slot 13, can force per one or two part pin inside.Under the normal condition, to the pin application of force of holding, so that it leans against on the end of the boring 14 in the lock cylinder, in this position, the contact surface between the external surface of its relevant drive pin leap cylinder and the inner surface in hole 11 is placed.Have all and cross over the drive pin that contact surface is placed in this way, prevented the rotation of cylinder in the body.Yet, when inserting correct key 21 in the key slots 13, the shank of the key 20 of key (on) engaging member 19 in the longitudinal edge surfaces 28 causes the pin that holds of different length all to shift to the position shown in Fig. 1.Wherein, the contact surface between the relevant drive pin in these pins and their, and the contact surface between the inner surface in the external surface of cylinder and hole 11 accurately matches, to such an extent as to by key can be in its lock body rotor.As can be seen, key has an arcuate section 22, and the shank of the key 20 extends from arcuate section 22, and the preceding free end of the shank of the key has an inclined surface 23, and the final engaging member of this surface from last longitudinal edge surfaces is to the terminal 23a extension previous dynasty.When key inserts so that when rising these pins, this terminal 23a is surface 23 subsequently, is meshed with the hemisphere-shaped lower surface of each pin that holds 16, to allow whole insertions of key.Shown in the dotted line among Fig. 1, key can have an ear handle or stopper 24, and when a key all suitably inserted, ear handle or stopper 24 engaged by ground mutually with the front surface of cylinder.Yet, as also will being mentioned, can under the situation of the such stopper that contacts with front surface cylinder of tool not, form the key of this configuration.
Having aspect ' locking ' element 25, lock of the present invention is different with traditional pin braking bolt-lock, when not putting a key in the lock, ' locking ' element 25 is positioned on the contact surface between the inner surface in the external surface of crossing over cylinder and the hole 11 in the body 10.As will being described, when putting a key in the lock and it is rotated,, be particularly suitable for allowing this blocking element to move in key at the key of this lock, the cylinder 12 in therefore can rotating hole 11, thus can operable lock.
As from Fig. 1 and 2 as can be seen, in this example, element 25 is the form of a ball type device, for example is the form of ball.Use the lock in the orientation shown in the figure, opposite with the inner peg diametric(al) of pin braking bolt-lock, and with the inner peg of pin braking bolt-lock, promptly with a position of axially arranging in a line at a distance of the place ahead pin farthest of slotting key as shown in Figure 1 of lock on, the inner surface portion in the hole 11 in a part ball recess 26 organizators 10.Yet, this groove 26 is axially arranged in a line with the position of this inner peg, be not necessary, as being described, use the key of appropriate change, along on the direction in the place ahead of leaving lock, the position of groove can surpass described inner peg, perhaps also can be on any position between the place ahead of lock and the described inner peg.As shown in FIG., the radial position of groove is such: it is positioned on the plane identical with hole 14, to such an extent as to lower part by the ball in groove 26, admitted, the remainder of ball can stretch into also and be in the conplane key slot 13 with described hole 14, and this is configured among Fig. 2 and is preferably illustrated.Yet, if necessary, for example,, can excise the corresponding bottom of cylinder of the opposition side of key slot 13 if used bigger ball, with when ball shifts out body, ball is contained on its position, as being described.In addition, if necessary, ball is contained in ' static ' position that it crosses over the contact surface place between cylinder and the body.
In illustrated embodiment, compare with other hole 14, extend the hole 14 of admitting the pin that holds in the cylinder, to such an extent as under situation about key not being inserted in the cylinder, be spring-loaded the hemispherical ends of the pin 16 that holds via its drive pin that is associated 27, with engage bearings, and its contact surface of crossing between cylinder and the body fixed, as shown in figs. 1 and 2.Use this configuration, will be extended, as shown in FIG., engage balls to guarantee pin 16 to drive pin 27, the drive pin that has extended length cross between cylinder and the body (on) contact surface.According to this configuration, assembling at the beginning, downward from the top of body, pass hole 14, insert ball, to such an extent as to it can be received in the groove 26, as shown in figs. 1 and 2, after this, in normal mode, in the pin 16 that holds, the drive pin 27 that has extended and spring 18 patchholes 14 and 15 at traditional pin brake bars lock.
Aspect a pin braking of operation bolt-lock, the difference of key of the present invention and traditional flat key is: at its free end, promptly, make the opposite longitudinal edge surfaces 29 of the shank of the key, i.e. the soffit of the shank of the key at its end away from arcuate section, as shown in figs. 1 and 2, remove backward or with its excision from terminal 23a, to form a groove 30, to allow when inserting key and rotating at that time, admit entire contact surface element 25, as being described.Owing between surface 28 and 29, defined the degree of depth of key, reduced its degree of depth so everything of the shank of the key removed.As shown in FIG., the excision among this embodiment reaches such degree: can form one and extend to the straight longitudinal edge surfaces 31 of groove 30 from described terminal 23a, this surface 31 is parallel to described edge surface 29.Groove 30 itself has part curved surfaces part 32, and extend to this a part of curved surfaces part 32 on surface 31; And a further straight surface portion 33 that extends to edge surface 29 from part 32, wherein surface 33 described relatively surperficial 29 is 90 °.For the reason that will be explained, groove 30 extends to a bigger degree of remainder than recess (i.e. part from groove to terminal 23a institute otch) to the inboard of the degree of depth of the shank of the key.
As what seen in can figure, in this embodiment, at the recess of the end of the key that has defined groove, the width of crossing over whole plane key extends.Therefore, as can be seen, groove provides the space in key, thereby also provides the space in the key slot of cylinder, be used for admittance to whole bearing, to such an extent as to, as being described, when correct key is inserted in the lock, and when it is rotated, it can shift out its groove 26, promptly shifts out any part of body, and leaves the contact surface at groove 26 places.As with understand, and it is as mentioned previously such, can be provided at along the hole 11 lower inner surface to blocking element Anywhere, be used for using together with the key of a relevant change, wherein recess or excision are extended fully from the free end of key, to such an extent as to can axially be positioned at groove 30 and groove 26 on the line when a key inserts in the lock fully.Therefore, if ball is located from the front end of lock further, need be located the end of the more approaching key shown in Figure 1 of groove 30, or need the shank of the key of a key to make more longerly.In addition, if the front end of the more approaching lock of ball is located, for example, arrange in a line with the pin of two parts of centre, so, to need than further being extended shown in the figure from the recess of the end of key, so that in alignment at the pin place and the ball of two parts in described centre to arcuate section.
When interior spring-loaded pin is configured to engage with ball 25, must the end of key be disposed, to satisfy engaging between this pin and the ball, to such an extent as to when a key inserts fully, it causes them to be separated from each other, and lifts pin along surface 23.Can be Any shape by the formed cavity of recess, still, must have the groove that ' being deeper than ' is positioned at the recess of end, shift out lock body fully to allow ball.
In addition, according to this illustrated embodiment, it is configured to: when not admitting key as yet in the lock, between all drive pin leap cylinders and the body (on) contact surface, ball is crossed over (descending) contact surface between cylinder and the body simultaneously, described in figure.Obviously, ball will prevent whole insertions of a standard key, be about to prevent a key that does not have recess at its end, and recess that has an otch but wherein recess be not enough to allow the key that pass through of end on ball that cut, or wherein whole insertions of the key of no-fix key tip that pin is lifted from ball.If notched foot is passed through on ball with the end that allows otch, and has correctly located key tip, it is possible inserting so completely.Yet if recess does not comprise ' darker ' part, ball will prevent the rotation of cylinder by key so, because for ball, does not exist in the key it is admitted the into space of key fully, and is external to be located at.
When inserting correct key 21, the pin of correct 4 two parts of engaging member labour contractor is raised to correct position, as shown in fig. 1, and to allow the rotation of cylinder.And correct end ' highly ' lifts pin from ball.In addition, the insertion of correct key makes darker groove 30 in alignment with ball after the end of the otch of key is passed from it, as shown in fig. 1.If described ear handle is provided, pass through the ear handle 24 of the front end of pitch cylinder so, can determine correct insertion position.In this position, can engage the surface portion 33 of groove with ball or can just leave it.In addition, if the adjacent segmental part does not provide ear handle or stopper of equal value, can be disposed it in this wise so:, make surface portion 33 as a stopper by directly engaging near ball at its locked position of coupler shown in Fig. 1.
No matter be which kind of situation, when key correctly being inserted and being rotated, because the angular movement of the shape cylinder of ball, to reach such degree: can produce the driving ball and upwards shift out its groove 26 lateral pressure outward, as from seeing Fig. 1 and Fig. 2, so that it is received in fully by in the 32 and 33 formed grooves 30 of surface.In case ball is received in the groove 30 fully, the continuation of key rotation causes cylinder angular movement with respect to body 10 in its hole 11, so that allow the normal running to lock.Obviously, after lock is operated, the rotation of key, thereby the rotation of the cylinder in opposite direction that produces, to turn back to it to ball and partly fall into once more being received within groove 26, thereby one of locking has a position of the insertion of incorrect otch and terminal key once more.As described, in case a key remove, the interior pin that holds 16 by biased downward on ball.
As stated, blocking element can be any optional, suitable form, and can be by spring along being setovered towards the direction of key.Thereby, for example, use configuration shown in Figure 1, can be configured to be better than bias spring on the blocking element 25 to spring 18, to such an extent as to when not putting a key in the lock, this element 25 keeps in position.Then, when a key inserts, and when lifting this terminal pin, since the insertion of key, the part that bias spring will force the contact surface element to enter the end otch of key, and when key all inserted, element 25 will be admitted in the groove 30.Thereby, use this configuration, before beginning to rotate blocking element, blocking element will be accepted in the key fully.
In one is optionally disposed, can reduce the width of blocking element, to such an extent as to therefore the end of key does not need to cross over its whole width otch.In other words, it will be only in a side or at the opposite side otch, or can be its otch medially, with the passage that provides to close at its corresponding opposition side.
As explained above, blocking element can not prevent the cylinder rotation, but can prevent the insertion of the key of incorrect ' shape '.Usually, cylinder is processed,, thereby strengthened their safety with suitable specific key profile.The present invention has introduced a kind of shape of the outline of key, but is not in order to satisfy a fixing lockhole.This mechanical device is dynamic, and its dynamic characteristic is that parts move, and requires the cavity of a certain depth in the key.
