具体实施方式
本发明的特定示例性实施例提供了一种可更换密钥的锁圆柱体，包括：圆柱体主体，该主体具有纵轴并形成纵向间隔、径向对齐的多个第一弹子腔，所述多个第一弹子腔中的每个都适于容纳相应的第一弹子，所述圆柱体主体还限定有穿过其中并纵向延伸的槽；和设置于所述圆柱体主体中的锁芯组件，所述锁芯组件包括限定有多个第二弹子腔的锁芯主体，所述多个第二弹子腔中的每个都适于容纳相应的第二弹子，所述锁芯主体可在所述圆柱体主体内的第一位置和第二位置之间旋转，所述第一位置使所述多个第二弹子腔与所述多个第一弹子腔对准，所述第二位置将所述多个第二弹子腔与所述槽对准，当所述锁芯主体处于所述第二位置时，所述多个第二弹子可以从所述多个第二弹子腔中移去。
本发明的特定示例性实施例提供了一种将锁圆柱体更换密钥的方法，包括下述步骤：将钥匙插入到设置于圆柱体主体内的锁芯组件中，所述圆柱体主体具有纵轴并且形成纵向间隔、径向对准的多个第一弹子腔，所述多个第一弹子腔中的每个都适于容纳第一弹子，所述圆柱体主体还限定有穿过其中纵向延伸的槽，所述锁芯组件设置于所述圆柱体主体中，所述锁芯组件包括限定有多个第二弹子腔锁芯主体，所述多个第二弹子腔中的每个都适于容纳第二弹子；将所述圆柱体主体内的所述锁芯组件从第一位置旋转到第二位置，所述第一位置使所述多个第二弹子腔与所述多个第一弹子腔对准，所述第二位置使所述多个第二弹子腔与所述槽对准，当所述锁芯主体处于所述第二位置时，所述多个第二弹子可从所述多个第二弹子腔中移去。
本发明的特定示例性实施例提供了一种系统，包括：连接在门上的可更换密钥的锁圆柱体，所述可更换密钥的锁圆柱体包括：圆柱体主体，该主体具有纵轴并形成纵向间隔、径向对齐的多个第一弹子腔，所述多个第一弹子腔中的每个都适于容纳相应的第一弹子，所述圆柱体主体还限定有穿过其中纵向延伸的槽；和设置于所述圆柱体主体中的锁芯组件，所述锁芯组件包括限定有多个第二弹子腔的锁芯主体，所述多个第二弹子腔中的每个都适于容纳相应的第二弹子；其中所述锁芯主体可在所述圆柱体主体内在第一位置和第二位置之间旋转，所述第一位置使所述多个第二弹子腔与所述多个第一弹子腔对准，所述第二位置使所述多个第二弹子腔与所述槽对准，当所述可更换密钥的锁圆柱体从所述门中取出并且所述锁芯主体处于所述第二位置时，所述多个第二弹子可从所述多个第二弹子腔中无破坏性地移去。
图1是本发明所述系统100的示例性实施例的前方透视图，图18和19是沿图1剖面线18-18所得的剖视图，图18示出了钥匙插入，图19示出了钥匙被移去。参照图1、18和19，系统100可包括钥匙110，锁圆柱体组件120，该组件包括圆柱体主体122，烟囱状件123(chimney)，和烟囱状件盖126，以及包含锁芯主体142的锁芯组件140。当钥匙110插入到锁芯组件140的钥匙槽146中，锁芯弹子145(plug pin)重新定位以符合钥匙110的切口，由此重新定位了位于烟囱状件123中的装载弹性件的圆柱体弹子125，这样就可形成剪切线150，从而允许锁芯组件140在圆柱体组件120内旋转。当钥匙110从钥匙槽中移去时，装载弹性件的圆柱体弹子125可将锁芯弹子145重新定位至其行程的底部，由此消除和/或阻断剪切线150并防止锁芯组件140在圆柱体组件120内旋转。系统100可安装在门上以锁定门防止其被打开，除非使用钥匙110将锁芯组件140从锁定位置旋转到开锁位置。
图2是本发明所述系统100的示例性实施例处于预更换密钥(pre-rekeying)位置的后部透视图。注意，所示圆柱体组件120绕其纵轴A-A相对于图1中圆柱体组件120的方向旋转了180度。因此，圆柱体主体122和烟囱状件123也都旋转180度。在该图中可看到，纵向槽130沿着圆柱体主体122长度的主要部分切穿圆柱体主体122的环形壁。在槽130中插入有槽盖170，该槽盖由槽盖定位器149保持在槽130中，该定位器可整合于锁芯主体142上。图中还示出了锁芯夹160，该夹用于限制锁芯主体142沿着纵轴A-A相对于圆柱体主体122进行移动。
图3是本发明所述系统100的示例性实施例的俯视图。图中示出了圆柱体组件120、圆柱体主体122、锁芯组件140和锁芯主体142。
图4是本发明所述系统100的示例性实施例的后视图。图中示出了烟囱状件123、圆柱体槽130、锁芯组件140、锁芯主体142、锁芯夹160和槽盖170。
图5是本发明所述系统100的示例性实施例沿图4剖面线5-5所得的剖视图。图中示出了圆柱体主体122，烟囱状件123，多个圆柱体弹子腔124，每个腔都适于基本上容纳一个装载弹性件的圆柱体弹子(未示出)，锁芯主体142，和多个锁芯弹子腔144，每个腔都适于基本上容纳一个锁芯弹子(未示出)。当正确的钥匙正确地插入到锁芯主体142中时，锁芯弹子(未示出)重新定位以符合钥匙的切口，从而重新定位了位于烟囱状件123中的装载弹性件的圆柱体弹子(未示出)，这样就形成了剪切线148，从而允许锁芯主体142在圆柱体主体122中进行旋转。
图6是本发明所述系统100的示例性实施例沿图5剖面线6-6所得的剖视图。图中示出了圆柱体主体122、锁芯主体142和锁芯弹子腔144。
图7是本发明所述系统100的示例性实施例沿图5剖面线7-7所得的剖视图。图中示出了锁芯主体142、钥匙槽146、夹的接合表面148和用于与锁芯主体142的夹的接合表面148相接合的锁芯夹160。
图8是本发明所述系统100的示例性实施例处于更换密钥位置的后部透视图。图8与图2相似，但是锁芯142处于更换密钥位置，槽盖170已被部分地移开以露出槽130和锁芯弹子腔144。注意，锁芯夹160的方向相对于其在图2中方向的变化，同时注意，因为槽盖定位器149(如图2所示)已经随着锁芯主体142旋转，所以槽盖170至少可部分地从槽130中纵向移开。
图9是本发明所述系统100的示例性实施例的俯视图。图中示出了圆柱体组件120、锁芯组件140和已部分移开的槽盖170。
图10是本发明所述系统100的示例性实施例的后视图。图中示出了圆柱体主体122、烟囱状件123、锁芯主体142、锁芯夹160和槽盖170。
图11是本发明所述系统100的示例性实施例沿图10剖面线11-11所得的剖视图。图中示出了圆柱体主体122，烟囱状件123，多个圆柱体弹子腔124，每个腔都适于基本上容纳一个装载弹性件的圆柱体弹子(未示出)，锁芯主体142。注意，多个锁芯弹子腔144相对于其在图5中的方向旋转了180度。同时注意，由于锁芯主体142的方向以及槽盖170至少从槽130中部分地移开，锁芯弹子(未示出)可以自由地从锁芯弹子腔144中移去或进入其中。
图12是本发明所述系统100的示例性实施例沿图11剖面线12-12所得的剖视图。图中示出了圆柱体主体122、锁芯主体142和锁芯弹子腔144。
图13是本发明所述系统100的示例性实施例沿图11剖面线13-13所得的剖视图。图中示出了锁芯主体142、锁芯钥匙槽146和锁芯夹160。注意，锁芯钥匙槽146相对于其在图7中的方向旋转了180度。
图14是本发明一个圆柱体的示例性实施例的后部透视图。图中示出了圆柱体主体122、烟囱状件123、至少一个圆柱体弹子腔124和槽130。
图15是本发明一个槽盖170的示例性实施例的透视图。图中示出了槽盖内部凸缘172，该凸缘可阻止槽盖170相对于圆柱体主体122(未示出)径向向外移动。图中还示出了槽盖外部凸缘174，该凸缘可阻止槽盖170相对于圆柱体主体122(未示出)径向向内移动。
图16是本发明一个锁芯夹的示例性实施例的透视图。图中示出了锁芯夹的突起162，该突起可与锁芯主体142(未示出)相互作用以阻止锁芯夹160相对于锁芯主体142的径向移动。图中还示出了锁芯夹的内壁164，该内壁可与锁芯主体142(未示出)相互作用以阻止锁芯夹160和/或圆柱体主体122(未示出)相对于锁芯主体142纵向移动。
图17是本发明一种方法200的示例性实施例的流程图。在步骤210中，正确的钥匙被插入到锁芯组件，由此重新定位了锁芯弹子和圆柱体弹子以形成和/或对准剪切线，以此允许锁芯组件在圆柱体组件中旋转。
在步骤220中，在钥匙上施加扭矩以使锁芯组件与圆柱体主体从锁定位置旋转到开锁位置和/或更换密钥位置。开锁位置可以产生在相对于锁定位置的任何方向，例如从大约10度到大约250度，并包括其间的各个数字，如大约30.05，62，90，118.7，150.03，180和/或224度等。更换密钥位置产生在相对于第一个锁定位置的任何方向，例如从大约10度到大约250度，包括其间的各个数字，如30.05，62，90，118.7，150.03，180和/或224度等。
在步骤230中，随着锁芯组件旋转到更换密钥位置，槽盖可以在槽内纵向滑动并且至少部分被移开。在步骤240中，至少一个锁芯弹子可从锁芯主体中移去。如果更换密钥位置垂直地朝向锁芯弹子腔，那么锁芯弹子可以从锁芯弹子腔中落下。注意，至少一个锁芯弹子可以从锁芯弹子腔中被移去，而不用移去锁芯夹或将锁芯主体从圆柱体主体中移去。还要注意，因为不需要将锁芯组件从圆柱体组件中移去，所以不需要锁芯随动机构来更换密钥。此时，可以移去旧钥匙，而插入新钥匙。
在步骤250中，至少一个锁芯弹子可用不同长度的锁芯弹子代替，由此需要不同的钥匙在圆柱体主体内旋转锁芯主体。然后，槽盖可被重新定位。
在步骤260中，随着新钥匙处于锁芯组件中合适的位置，新钥匙可以被旋转到锁定或开锁位置。
因此，本发明的实施例可以提供一种快速地使锁圆柱体更换密钥而不需要锁芯随动机构或将锁芯组件从圆柱体组件中移去的方法。此外，在本发明的特定实施例中，更换密钥者不需要移去圆柱体烟囱状件的盖、圆柱体弹子弹性件或圆柱体弹子。
虽然本发明已经参考其特定示例性实施例得以描述，但是可以理解，许多的变种、修改和另外的实施例都是可能的，并且相应地，所有这些变种、修改和实施例都被看作处于本发明的实质和范围之内。而且，这里专门讨论和指出的参考文件通过引用的方式进行结合，并在这里进行完整的阐述。相应地，附图和说明书实质上都被看作示例性的而不是限制性的。
