    • A hinge assembly for hingedly connecting a cover and a housing theretogether, such as a keypad cover and a housing of a portable radiotelephone. A generally tubular hinge arm is formed at an end portion of the cover, and two hinge pins, each having identical cam surfaces formed upon edge surfaces thereof are inserted into the hinge arm and positioned such that the cam surfaces of the respective hinge pins extend beyond opposing sides of the hinge arm such that the hinge pins are caused to rotate in unison with rotation of the cover. A spring member is tandemly-positioned between the two hinge pins to exert spring forces thereupon. Two cam followers are affixed to the housing in a manner such that the cam surfaces of the hinge pins abut against the cam followers. The cover may be rotated between an opened and a closed position and forces exerted upon the cam surfaces of the hinge pin by their abutting engagement with the cam followers urge the cover into or out of the open and closed positions during rotation of the cover, and urge the cover to remain in the open or the closed position in the absence of rotational moments exerted thereupon by the spring forces exerted upon the hinge pin by the spring member.
    • 一种用于将盖和壳体一体地铰接地连接的铰链组件,例如键盘盖和便携式无线电话机的壳体。 在盖的端部形成有大致管状的铰链臂,并且在铰链臂上插入两个铰链销,每个铰链销的边缘表面上具有相同的凸轮表面,并且定位成使得相应铰链销的凸轮表面延伸超过 铰链臂的相对侧使得铰链销在盖的旋转中一致地旋转。 弹簧构件串联地位于两个铰链销之间,以在其上施加弹簧力。 两个凸轮从动件以使得铰链销的凸轮表面抵靠凸轮从动件的方式附接到壳体。 盖可以在打开和关闭位置之间旋转,并且通过它们与凸轮从动件的邻接接合而施加在铰链销的凸轮表面上的力在盖旋转期间促使盖进入或离开打开和关闭位置,并且 在没有由弹簧构件施加在铰链销上的弹簧力施加的旋转力矩的情况下,推动盖保持在打开或关闭位置。
