具体实施方式
本发明的一实施例针对一种使用带延伸部分的钥匙的锁定装置。该锁定装置可以是圆柱形锁。在一实施例中，锁定装置包括锁定心轴以及驱动结构，锁定心轴包括多个锁定心轴孔和沿锁定心轴的轴向长度轴向延伸的通道，驱动结构包括多个驱动结构孔。(如本文所使用的，“沿轴向长度”包括至少部分地沿锁定心轴的一部分延伸的通道。)驱动结构和锁定心轴之间的界面形成剪切线。该锁定装置还包括多个锁定心轴孔内地多个组合销、以及驱动结构内驱动结构孔内的多个驱动销，多个驱动销分别与多个组合销关联。钥匙的延伸部分可精确地或靠近剪切线延伸以提供用于锁定心轴的临时坚固的界面部分。于是，当使用经准许的钥匙锁定和/或解锁锁定装置时，驱动结构内的驱动销留在剪切线的一侧上。
根据各实施例的锁定装置可用于固定或防止任何适当类型的物件的偷窃。这些物件包括自行车、家具等。但是，可通过根据本发明的实施例固定的物件较佳的是便携式电子装置。便携式电子装置的实例包括便携式计算机(例如膝上计算机)、无线电话、便携式音乐播放器、DVR(数字摄像机)、平板显示器和电视机等。
图1示出根据本发明的实施例的锁定机构100。锁定机构100包括钥匙20和锁定装置102。这些部件，单独或与其它部件结合可形成根据本发明实施例的锁定机构。
钥匙20包括手柄22、延伸部分26和延伸部分26和手柄22之间的编码部分24。下文将更详细地描述这些特征。
锁定装置102包括壳体90。在该实例中，壳体90可包括管状或圆柱形结构。它可由不锈钢或任何其它坚硬材料制成。
缆绳30等可附连到壳体90。缆绳30可以是不锈钢缆绳等。在一些实施例中，缆绳30的远端可包括一个圈。为了将物件固定到不可移动的物体(例如书桌)上，缆绳30可围绕不可移动的物体(例如桌子腿)环住且锁定装置的头部可穿过该环。锁定装置102可使用锁定装置102内的锁定件附连到物件上。在某些情况下，该物件可包括锁定件插入穿过的狭槽。然后可再行该锁定件构造成锁定位置以将锁定装置的的头部固定到物件上，并随后锁定到可移动物体上。
各种部件可在锁定装置102的壳体90内。例如，如图1所示，锁定心轴42协作地与壳体90内的驱动结构44配合。在本发明的实施例中，锁定心轴42可相对于驱动结构44转动。可通过驱动结构44和锁定心轴42之间的界面来限定剪切线S。
锁定心轴42在靠近锁定装置102前部具有近端42(a)且在靠近锁定装置102后部具有远端42(b)。如图1所示，锁定心轴42的远端42(b)穿过驱动结构44的中心。当锁定销和驱动销不跨越剪切线S时，锁定心轴42可相对于驱动结构44转动或旋转(顺时针或逆时针)。
近端42(a)包括圆柱形部分，该圆柱形部分包括多个锁定心轴孔42(c)。锁定心轴孔42(c)轴向延伸在锁定心轴42的近端42(a)穿过锁定心轴42的圆柱形部分。多个组合销(未示出)可分别设置在锁定心轴孔42(c)中。组合销可具有不同的长度并可对应于钥匙20的编码部分24的槽口部分。如果需要，驱动销还可具有不同的长度。
通道51位于锁定心轴42中并构造成接纳钥匙20的延伸部分26。通道51还可具有任何适当的截面形状(例如圆形)。在本发明的各实施例中，通道51可以是在锁定心轴42的一侧的开口通道的形式，或者可以是锁定心轴42内关闭通道的形式。在两种情况下，当使用钥匙20来将锁定装置102从锁定构造改变到解锁构造时，通道51都构造成可接纳钥匙20的延伸部分26，或反之亦然。钥匙20的延伸部分26的远端延伸到剪切线S以填充通道51并在截面S处临时提供用于锁定心轴42的实心表面。如下文将更详细地解释的那样，这可防止驱动结构44内驱动心轴孔44(a)内的驱动销位于剪切线S上。
如图1所示，驱动结构44可包括多个驱动心轴孔44(a)。驱动心轴孔44(a)也轴向延伸穿过驱动结构44。它们还可设置在围绕驱动心轴44的中心轴线的圈内。驱动销(未示出)可分别设置在驱动心轴孔44(a)中。多个弹簧36还可分别设置在驱动结构孔44(a)内。这些弹簧36将驱动销(未示出)推向剪切线S。
在正常操作中，当锁定装置102处于锁定构造时，一个或多个向前偏置的驱动销跨越剪切线S。这可防止锁定心轴42相对于驱动结构44转动并防止附连到锁定心轴42的锁定件移动。当锁定装置102处于非锁定构造时，驱动销可由锁定销孔42内的相应组合销向后推。钥匙的编码部分24具有不同深度的切口，从而将组合销向后推动不同的距离。当组合销被向后推时，驱动销在剪切线S的一侧上，同时组合销在剪切线S的另一侧上。由于组合销和驱动销在剪切线S处彼此分开，这使锁定心轴42能够相对于驱动结构44转动。
驱动销和组合销可由任何适当的结构形成并可由任何适当的材料制成。例如，销可以是钉、柱、直圆柱、带有头部的圆柱等。
现将描述通道51和钥匙20的延伸部分26的操作。当锁定装置102在非锁定位置时，驱动销64可朝向锁定装置102的前部偏置，可穿入相应的锁定心轴孔42(c)，并可位于剪切线S上。为了转动锁定心轴42和附连到锁定心轴42上的锁定件(未示出)以锁定装置102进入非锁定构造，钥匙20插入锁定装置102的钥匙沟，且钥匙的延伸部分26延伸到通道51内。当锁定心轴42相对于驱动结构44转动时，延伸部分填充通道51并将驱动销64保持在剪切线S的一侧上。
如果有人试图将诸如圆珠笔的管之类的未经准许的管状结构插入锁定装置102的钥匙沟内，则圆珠笔的模制管就不能穿过通道51的整个轴向长度。即使未经准许的使用者成功地部分转动锁定心轴42，锁定心轴42也不能完全旋转。由于未经准许的使用者试图在锁定装置102的钥匙沟内转动未经准许的管状结构，驱动结构孔44(a)-1与通道51对准。由于在通道51内没有相应的组合销且由于未经准许的管状结构(未示出)未将通道51填充到剪切线S，当通道51与驱动结构孔44(a)-1对准时，驱动销64会由于弹簧36而跨越剪切线S向前偏置。因此，未经准许的使用者不能将锁定心轴42相对于驱动结构44完全转动，且因此不能打开锁定装置102。
在上述较佳实施例中，如果使用未经准许的管状结构来转动锁定心轴，该通道构造成可接纳驱动销之一。但是，在其它实施例中，在驱动心轴孔存在有一个除了驱动销之外的其它构件(例如球、方形、棱锥等)，且该结构还可防止使用未经准许的管状结构来作为锁定和/或解锁装置。在这些替代实施例中，该结构可与诸如弹簧之类的偏置件位于驱动心轴孔内。偏置件可将该结构朝向剪切线偏置。如果具有延伸部分的钥匙插入锁定装置的钥匙沟内，且如果延伸部分延伸到剪切线，则偏置结构会保持在剪切线的驱动心轴侧上。如果将未经准许的管状结构插入锁定装置的钥匙沟内，则未经准许的管状结构不能延伸到剪切线。当使用未经准许的管状结构来转动锁定心轴时，驱动心轴孔会与通道对准。然后偏置结构会穿入通道并会位于剪切线上方，由此防止锁定心轴的进一步旋转并防止经准许的管状结构锁定和/或打开锁定装置。
图2示出根据本发明的实施例的钥匙20。钥匙20包括手柄22、联接到手柄22的带有槽口28的编码部分24、以及从编码部分24延伸的延伸部分26。在该实例中，编码部分24可以是圆形的。
延伸部分26可以是延伸的钥匙对准凸起部。延伸的对准凸起部具有两种功能。对于使用者，它可用作对准引导件，从而使用者可将钥匙20的编码部分28与锁定装置102的钥匙沟对准。如上所指出的，对准凸起部也可用于将锁定心轴内的通道填充到锁定装置内的剪切线。这就可防止驱动销进入锁定心轴42内的通道51。
图3示出沿图1的线3-3的锁定装置的正视剖视图。如图3所示，在驱动多个驱动结构孔44(a)，驱动结构44设置在壳体90内。在该实例中，有六个成圆形布置的驱动结构孔44(a)。为了清楚示出，示出一个孔44(a)中的一个驱动销64。通常，在每个驱动结构孔44(a)中有一个驱动销。
图4示出沿图1的线4-4的锁定装置的正视剖视图。如图4所示，在锁定心轴42上有多个锁定心轴孔42(c)。锁定心轴42设置在壳体90内。锁定心轴42的对准区域42(d)形成上述通道51的一部分。对准区域42(d)是开口通道的形式。
图5示出根据本发明的实施例的锁定装置102的正视图。在图5中，示出对准区域42(d)和壳体90。对准区域的功能及其相应的通道对于终端用户和未经准许的用户来说并不非常明显。
图6示出锁定装置的一部分的局部剖切立体图。在该图中，更清楚地示出组合销62和驱动销64。组合销62在锁定心轴42的锁定心轴孔42(c)内。驱动销64和相应的弹簧36在驱动结构44内的驱动心轴孔44(a)内。锁定心轴42和驱动结构44之间的界面形成剪切线S。如图所示，当驱动销64与剪切线S交叠时，锁定心轴42不能相对于驱动结构44完全旋转。
图7和8示出经准许的钥匙和未经准许的管状结构怎样在根据本发明的实施例的锁定装置内工作的。为了清楚地示出，在这些图中示出了销但未示出其相应的孔。
图7示出当在锁定装置中使用经准许钥匙时驱动销和组合销是怎样定位的示意图。在该实例中，将钥匙20插入锁定装置的钥匙沟内。钥匙20的编码部分24将左边一对组合销推下，由此将驱动销64推到剪切线S下方。钥匙20的延伸部分26延伸到剪切线S并穿过通道51。于是，当锁定心轴42相对于驱动结构44旋转时，各驱动销64留在剪切线S下方。
图8示出当在锁定装置中使用未经准许管状结构120时驱动销和组合销是怎样定位的示意图。如图所示，当未经准许的使用者试图将未经准许的管状结构120推入钥匙沟以转动锁定心轴42时，变形的管状结构120不具有一直向下延伸到剪切线S的部分。因此，当未经准许的使用者试图旋转锁定心轴42时，驱动销64(a)向上偏置到通道51内，如箭头12所示，并跨越剪切线S。这就可防止锁定心轴42相对于驱动结构44进一步旋转。
图9示出根据本发明的另一实施例的锁定装置的立体图。锁定装置包括十字件或T形条形式的锁定件124、以及一对锁定销130。锁定销124可联接到上述锁定心轴，使得它可在锁定心轴旋转时旋转。如图所示，锁定件的十字条部分可与销130对准。它们可一起插入安全狭槽等。
图10示出延伸穿过便携式电子装置的壳体70内安全狭槽72的锁定装置的销和锁定件。如图所示，在将锁定件的十字条部分插入带有销的狭槽内时，将锁定件转动，而使十字条垂直于狭槽72的定向而定向。这就可将锁定装置固定到壳体70。在本发明的实施例中，安全狭槽较佳地通常为矩形和/或具有约3mm乘约7mm的尺寸。小的安全狭槽不会显著改变便携式电子装置的美观，但可用于防盗。例如，如果盗贼试图将锁定装置与便携式电子装置分开，就会损坏便携式电子装置，由此损坏其价值。
美国专利No.6,006,557和No.5,502,989中描述了可用在根据本发明的实施例的锁定装置中的其它特征，其全部内容以参见的方式纳入本文以用于所有目的。
本发明的实施例提供了多种优点，例如，未经准许使用者不易察觉到上述锁定心轴内存在细长通道。因此，当未经准许使用者试图撬锁时，未经准许使用者不会明白锁为什么撬不开。此外，本发明的各实施例可相对容易地包含在圆柱形锁中，且不需要复杂的更改。
以上说明书是说明性的而非限制性的。阅读了本说明书之后，本发明的很多变型对本领域的技术人员来说是显而易见的。因此不应当参照以上说明来确定本发明的范围，而应当参照待审查的权利要求和其全部范围或同等物来确定。此外，一个实施例中的任何一个或多个特征可与其它实施例的任何一个或多个特征组合而不背离本发明的精神和范围。
关于诸如“后”、“前”、“顶”、“底”、“上”、“下”等的位置的含义，可参照附图，都是为了方便而用的。并不意味着它们是指绝对的位置。
“一个”或“该”的表述想要表达的意思是“一个或多个”，除非具体地有相反表示。
以上所体积的所有的专利、专利申请、公开物和说明书的全部内容都以参见的方式纳入本文以用于所有的目的。但全都不承认为现有技术。
