    • An accessible pedestrian pushbutton station. The station includes an articulating rear mounting structure to facilitate accurate positioning of the station on either a curved or flat surface. Additionally, slots in the rear mounting structure allow for minor positional adjustments during installation. The crossing direction arrow is easily repositioned on the front of the station without disassembling the housing. After removing the screw-mounted arrow, the plunger can be turned clockwise or counter-clockwise using only a flat-head screw driver. The plunger is balanced between oppositely biased springs. The spring-balanced plunger indirectly actuates an offset piezo bender using a flexible spring actuator and a second, offset stem bumper. This protects the piezo bender from direct pressure and potential damage. The station includes an internal speaker and the housing includes bilateral sound vents to project the sound emitted by the speaker. Baffles may be inserted in one or both of the sound vents.
    • 一个无障碍的行人按钮站。 该车站包括一个铰接的后安装结构,以便于车站在弯曲或平坦表面上的精确定位。 此外,后安装结构中的槽允许在安装期间进行微小的位置调整。 交叉方向箭头很容易重新定位在车站的前方,而不拆卸外壳。 拆下螺钉安装的箭头后,只能使用平头螺丝刀将柱塞顺时针或逆时针转动。 柱塞在相对偏置的弹簧之间平衡。 弹簧平衡柱塞使用柔性弹簧致动器和第二偏置杆保险杠间接地驱动偏移压电弯曲机。 这样可以保护压电弯管机免受直接的压力和潜在的损坏。 该车站包括一个内置扬声器,并且该房屋包括双边通风口,用于投影扬声器发出的声音。 挡板可插入一个或两个声孔。

    • A power saw tool including a housing, a motor, and a reciprocating shaft. A blade clamp assembly is mounted to the reciprocating shaft and adapted for gripping a saw blade. The blade clamp assembly includes a main body defining a channel for engaging the saw blade. A latch arm is pivotally attached to the main body and rotatable about a pivot axis. A locking catch extends from the latch arm and retains the saw blade within the channel. A latch release extends from the latch arm. An actuator is provided to selectively engage the latch release and permit removal of the saw blade from the blade clamp assembly. The power saw tool may include a speed limiter housed within the handle grip to delimit rearward travel of the trigger switch, thereby restricting the speed of the motor. The power saw tool may also include a rotatable shoe assembly.
    • 一种电动锯工具,包括壳体,马达和往复轴。 刀片夹组件安装在往复轴上并适于夹紧锯片。 刀片夹具组件包括限定用于接合锯片的通道的主体。 闩锁臂可枢转地附接到主体并且可围绕枢转轴线旋转。 锁定钩从闩锁臂延伸并将锯片保持在通道内。 闩锁释放从闩锁臂延伸。 提供致动器以选择性地接合闩锁释放并且允许锯片从刀片夹具组件移除。 动力锯工具可以包括容纳在把手把手内的限速器,以限制触发开关的向后行进,从而限制电动机的速度。 动力锯工具还可以包括可旋转的鞋组件。
