用于收纳和弹出钥匙的保持器。
专利摘要
钥匙单元被接收在壳体中的钥匙单元接收腔内，并且枢转地连接到壳体，以便在第一位置和第二位置之间枢转运动，在第一位置中钥匙单元基本上位于钥匙腔内，在第二位置中钥匙单元向外延伸或与壳体中的开口端对齐。钥匙单元安装销横跨腔延伸并进入钥匙单元头部的开口中。弹簧定位在安装开口中，并包括围绕安装销的螺旋部分。弹簧具有连接到壳体的第一端部分和连接到钥匙单元的第二端部分。钥匙单元通过所述安装销枢转地连接到壳体，以便在第一位置和第二位置之间枢转运动，在第一位置中钥匙单元基本上位于钥匙单元接收腔内，在第二位置中钥匙单元从腔的开口端向外突出。弹簧将钥匙单元偏压到第二位置。钥匙单元可由手从第二位置移动到第一位置，并且钥匙单元的这种移动将能量储存到弹簧中。弹簧中储存的能量将钥匙单元从其第一位置移动到其第二位置。
Original abstractA key unit is received within a key unit receiving cavity in a housing and is pivotally connected to the housing for pivotal movement between a first position in which it is substantially within the key cavity and a second position in which it extends outwardly from or is aligned with an open end in the housing. A key unit mounting pin extends across the cavity and into an opening in the head of the key unit. A spring is positioned in the mounting opening, and includes a helical portion surrounding the mounting pin. The spring has a first end portion connected to the housing and a second end portion connected to the key unit. The key unit is pivotally connected to the housing by said mounting pin, for pivotal movement between a first position in which it is substantially within the key unit receiving cavity, and a second position in which it projects outwardly from the open end of the cavity. The spring biases the key unit into the second position. The key unit is hand movable from the second position into the first position and this movement of the key unit stores energy into the spring. The stored energy in the spring moves the key unit from its first position into its second position.
