摘要： A manually operable pin for a wrist watch band comprising a pair of hollow, tubular members in telescopic relation. The members have extending pintles at their outer ends for engaging the watch bail openings. The inner member has a longitudinal slot spaced from the inner end. The outer member has a manually engageable tab extending upwardly adjacent its inner end. Spaced from the tab, a portion of the body extends inwardly into the slot on the inner member to permit relative telescopic movement within the limits of the slot. A coil spring is mounted within the members to normally bias the members in extended position. To lock the pin to a watch bail after it has been inserted in the end of a watch band, the pintle on the inner member is placed into one bail opening. The tab is manually moved against the action of the spring to shorten the pivot pin and allow the pintle on the outer member to be inserted in the other watch bail opening. The pivot pin is removable in the same manner, by manually engaging the tab and telescoping the members to shorten and remove the pin. No tool is necessary to insert or remove the pivot pin.

摘要翻译： 一种用于腕表带的可手动操作的销，其包括一对伸缩关系的中空管状部件。 这些构件在其外端具有延伸的枢轴，用于接合手表吊环开口。 内部构件具有与内部端部间隔开的纵向狭槽。 外部构件具有相对于其内端向上延伸的可手动接合的突出部。 从凸片间隔开，主体的一部分向内延伸到内部构件上的狭槽中，以允许在狭槽内的相对伸缩运动。 螺旋弹簧安装在构件内以使构件在伸出位置处正常地偏置。 将销钉插入表带末端后将其锁定到挂钩上，将内部构件上的销钉放入一个吊环开口。 手动移动卡舌以克服弹簧的作用，以缩短枢轴销，并允许外部构件上的枢轴插入另一个手表吊环开口。 枢轴销以相同的方式可拆卸，通过手动接合突片并伸缩构件以缩短并移除销。 无需插入或拆卸枢轴销即可。
