    • There is disclosed a compact telephone instrument with a telescoping operation. A first housing has a conventional telephone receiver located within a hollow recess thereof. The housing is removably secured to a bottom housing which contains a dialer assembly. A series of guide mechanisms are formed in both housings and are used to accommodate a third housing containing a telephone transmitter. The third housing is slidably mounted within the receiver and dialer housings to enable on-hook and off-hook operations by sliding and extending outwardly for off-hook operation and by pushing the housing inward for on-hook operation. The transmitter housing is accurately guided between the receiver and dialer housings by means of the guide mechanisms to insure accurate and reliable operation relatively independent of the nature of the force exerted by a user on the transmitter housing when operating the instrument. The movement of the transmitter housing between the on and off hook positions automatically activates a hook switch arrangement by means of tabs which are permanently secured on slide members associated with the transmitter housing and which tabs actuate leaf spring switches located on a component board positioned between the dialer and receiver housings. The telephone instrument employs conventional telephone components to further assure reliable electrical and mechanical operation.
    • 公开了一种具有伸缩操作的小型电话仪器。 第一壳体具有位于其中空凹部内的常规电话接收器。 壳体可移除地固定到包含拨号器组件的底部壳体。 在两个壳体中形成一系列导向机构,并且用于容纳包含电话发射器的第三壳体。 第三壳体可滑动地安装在接收器和拨号器壳体内,以通过滑动并向外延伸以进行摘机操作并且通过向内推动壳体以进行挂机操作来实现挂机和摘机操作。 变送器壳体通过引导机构被准确地引导在接收器和拨号器壳体之间,以确保准确可靠的操作,而不依赖于用户在操作仪器时施加在发射器外壳上的力的性质。 变送器壳体在开启和关闭位置之间的运动通过突出部件自动启动钩开关装置,该突片永久地固定在与变送器壳体相关联的滑动构件上,并且哪些接头片起动位于位于 拨号和接收机外壳。 电话机采用传统的电话部件来进一步确保电气和机械操作的可靠性。
