Description

多点门闩拉杆滚柱系统
发明背境
1．发明领域
本发明总的涉及闩锁装置，尤其涉及多点闩锁铰链门或面板等的系统。
2．现有技术简要说明
人们已知各种型式的用于固定门、面板等的闩锁装置。
在某些诸如在关闭时需密封的门或面板的应用中，采用多点闩锁系统是有利的。在这些系统中，将多点门闩安装在被密封的门或面板的边缘或边缘附近处。多点门闩可各自动作。然而，如果它们配置成由单个中央作动装置进行动作将更方便。一个已知的多点作动系统的例是可从Southco,Inc.,Concordville,PA.买到的VICE ACTION三点压缩系统。在该系统中，在要被固定的门或面板的边缘附近安装一对跨中心的门闩。通常，在门或面板与相应的框架或柜之间会装有可压缩的衬垫。在这些跨中心门闩间的面板上安装一中心作动门闩。该中心作动门闩可围绕垂直于面板平面的轴线转动，它包括一根当转动门闩时而转动的作动器杆或板。该中心作动门闩还包括一个手柄或旋钮，它在面板的表面上方延伸，或包括一个要被插入来转动中心作动门闩的工具的附件。一对拉杆自作动器板延伸至该跨中心门闩，因此由于拉杆在平行于该面板的平面中移动，而当转动中心门闩时，该跨中心门闩各自动作。当转动该中心门闩时，该跨中心门闩首先闩锁，然后压缩该衬垫，借此将面板闩锁和密封于框架。
在另一种型式的多点闩锁系统中，拉杆端部装有滚柱，并由装在门边缘附近的拉杆导向件支承。当门在打开位置时，拉杆收回。当面板门关闭时，转动该门闩作动装置，该拉杆延伸至面板门边缘以外，并与柜框架表面相接合，借此使面板闩锁于柜上。
还需要一个平缓操作的多点闩锁系统，它易于操作，并可方便地紧闭诸如通讯设备外壳之类的壳体。
发明概述
本发明提供一个适用于装在面板上并将面板紧固于框架的拉杆一滚柱闩锁系统。该拉杆一滚柱闩锁系统牢固、精微且易于操作，仅需操作人员施加最小的力。该闩锁系统适用于可由中心闩锁操作，并包括一个适于由垂直于该面板的中心门闩转动的棘爪。该闩锁系统还包括至少一个将面板紧固于框架的远距离闩锁装置，及一个延伸于棘爪和该至少一个远距离闩锁装置间的相应拉杆装置，从而当转动棘爪时，使该至少一个远距离闩锁装置工作。此外，该闩锁系统包括至少一个用于使相应拉杆装置的动作定位和导向的拉杆导向安装部件。该拉杆导向安装部件包括一个用于可移动地容纳一个相应拉杆装置的拉杆导向支承套和一个用于将该拉杆导向安装部件固定于面板的拉杆导向安装托架。最好，该支承套由诸如具有静磨擦系数低于约0.4的低磨擦系数材料制成。该托架适于容纳和紧固相应的拉杆导向支承套。最好，该拉杆导向支承套包括多个用于将拉杆导向支承套装于拉杆导向安装托架内的舌片。
最好，拉杆装置具有至少一条在拉杆导向安装部件附近在其内形成的导槽，而该拉杆导向安装部件包括至少一个导向装置，它适于被容纳在至少一条导槽内以便当该闩锁系统被作动时使拉杆装置的运动得到导向。而且最好，该拉杆导向支承套具有一个被成形来容纳和支承该拉杆装置的孔。
在现在的优先实施例中，该拉杆装置具有形成一导槽的大致U形截面，该导槽具有一对对置的大致平行的内表面和一对相应对置的外表面。因此，该导向装置具有一对对置的大致平行的表面，并且，当拉杆装置被容纳在拉杆导向安装部件中时，该导向装置处于拉杆装置的对置内表面附近。最好，在此实施例中，该导向装置还包括一对延伸至孔内的舌片。每个相应的舌片均具有在相应舌片端部形成的一个大致平面的导向表面，而当该拉杆导向件被容纳在拉杆导向安装部件内时，每个导向表面外于拉杆装置的该对对置外表面之一附近。
最好，该拉杆导向支承套包括多个用于将拉杆导向支承套装于拉杆导向安装托架内的舌片。

详细说明
本发明的拉杆滚柱系统被用来和中央闩锁件一起使用，以构成一个多点闩锁系统。
本发明提供一个在一个或多个部位牢固而容易地闩锁柜门又易于从中心闩锁件拆下的改进后的拉杆滚柱系统。
现详细参考附图，其中，在几个视图中，相同的表号表示相同的元件，图1表示自柜100内看的柜100的局部顶视图，柜100具有装在门102上的本发明的一个拉杆滚柱系统10。门102通过铰链(未示出)装于柜100上，并盖住开口104，该开口具有与门102相同的形状但尺寸略小些，以便当门102关闭时，门102延伸至开口104以外。柜100接近开口104的部分作为门102的框架106。此外，在门开口104附近的柜100内形成和本发明的拉杆滚柱系统10一起使用的凹穴108。在门102的内面周边附近固定由可压缩材料制成的衬垫110以有助于当门关闭时密封该柜100。柜100和门102可由任何适当的材料(例如钢)制成，用以封闭装于其中的各种设备(未示出)。
拉杆滚柱系统10适于可通过转动中心操作件或门闩25(图3)来工作。拉杆滚柱系统10包括一个大致“T”形的由钢之类强度好耐久性好的材料制成的棘爪20，其上具有一个用以将棘爪20固定于中心门闩25的长方形中心安装孔22，这样中心门闩的工作使棘爪20在打开或未闩锁位置与关闭或闩锁位置之间转动90度角。棘爪20具有一对对置的臂24，通过铆钉26将一对作动器拉杆30可转动地固定于其上。棘爪20还包括一个在该对置臂24的公共平面下延伸的第三臂(在图3清晰可见)，当拉杆滚柱系统10处于关闭或闩锁位置(图2和3)时，它直接与框架106内面接合，以有助于将门102紧固于柜框架106。
拉杆作动装置30最好由诸如铝或铝合金之类强度好，重量轻的材料制成。拉杆作动器30可包括一个在其内形成的导槽，即最好可由槽形型材制成。在每个拉杆作动装置30的一端44，切去导槽的侧面48，以便棘爪20的两个对置臂24可自由转过整个90°角。
在每个拉杆作动器30的对置端，将滚柱40可旋转地装于一相应销42上，滚柱40的旋转轴线位于平行于柜门102的平面。在作动器拉杆30的端部，将作动器拉杆侧面48的拐角倒角，滚柱40的尺寸和在作动器拉杆端部的位置要定得使滚柱40稍微凸出于端部46以外，并在作动器拉杆30的侧面48的正下方。当拉杆滚柱系统10自打开或收回位置(图1和图4)转至关闭或接合位置(图2和3)时，滚柱40与为此目的而在柜100的框架106中形成的凹穴108相接合，借此使门102压靠在框架106，并压缩其间的衬套110。滚柱40最好由尼龙等强度好、磨擦系数低的材料制成。
为此，用拉杆导向部件50将作动器拉杆端部46定位于门102上。每个拉杆导向部件50包括一个用适当的紧固件54固定于门102内侧的大致U形安装托架52。每个拉杆导向部件50还包括一个最好由强度好且具有诸如静磨擦系数低于0.4的低磨擦系数的材料，例如尼龙制成的拉杆导向插入件或支承套60。支承套60适于卡在安装托架52内适当的地方，以便借助于在侧面和顶部形成的多个弹性舌片61快速装配。因此，安装托架52适于容纳作固定相应的支承套60。
正如图8,9和11清楚地可见，支承套60包括一个适于容纳作动器拉杆30的上部舱62和下部舱64，该上部舱或孔62与下部舱64由大致水平支承壁66分隔。将该上部舱62成形成能容纳和支承该作动器拉杆30。该上部舱62的高度要选择得当操作拉杆滚柱系统10时其顶部和底部内表面会引导拉杆作动器30的运动。上部舱62包括一对对置的大致水平的导向壁68，其尺寸和位置定得当拉杆滚柱系统10被操作时能与作动器拉杆30的侧面48的外表面对齐。上部舱62还包括一大致平面的且大致横向的内导向壁70，它自上部舱62内的支承套60后部附近的水平支承壁66上表面向上及向前延伸至支承套60的前面附近(从图8,9和11中清晰可见)。内部导向装置或壁70适于在作动器拉杆30的侧面48的内表面之间延伸，并当操作拉杆滚柱系统10时引导作动器拉杆30的运动。在其后部，在顶部外表面与支承套60的侧面形成一法兰72，以便当支承套60被导入安装托架52内时，支承套60会牢牢地夹持在法兰72和弹性舌片61之间。下部舱64还包括一大致横向的中间支承壁74，以增加支承套60的强度和刚度。
工作中，拉杆作动器30(1)移过支承套60和(2)在稍微横向地在平行于柜门102的平面内移动，如可比较图1和2看见的那样。本发明的拉杆滚柱系统10提供这种作动动作，同时又可很好地为作动器拉杆端部46提供牢固的支承，使门102可可靠地压靠于柜框架106。
在本发明装置的各种实施例的细节方面可作各种修改，所有这些修改均处在由所附属权利要求书限定的本发明的精神和范围内。
