    • An electric toothbrush comprising an elongated body portion and a head including a static portion and a circular portion, a handle, and an angled shaft between the head and the handle. The circular portion rotates or reciprocates about an axis normal to a longitudinal axis of the head. The circular portion includes stiff bristles and the static portion includes soft bristles. The elongated body portion is hollow and further includes a motor in the hollow portion, which is operatively connected to the circular portion for rotating or oscillating or reciprocating the circular portion. A battery is located within the hollow section for powering the motor. A switch is operatively connected to the motor to provide momentary and continuous operation of the toothbrush. A worm gear and a pair of step gears are located in the hollow portion. The motor is operatively connected to the worm gear and the step gears are operatively connected to the worm gear and to each other. One of the step gears is offset with respect to a longitudinal axis of the elongated body portion. A shaft which is operatively connected to the offset step gear and to a second end to the circular portion. Alternately, the toothbrush comprises a plurality of gears and swivel arms which move the brush head moving portion in a rotating, oscillating or reciprocating manner.
    • 一种电动牙刷,包括细长主体部分和头部,头部包括静止部分和圆形部分,手柄以及头部和手柄之间的成角度的轴。 圆形部分围绕与头部的纵向轴线垂直的轴线旋转或往复运动。 圆形部分包括刚毛,静态部分包括软毛。 细长主体部分是中空的,并且还包括在中空部分中的电动机,其可操作地连接到圆形部分,用于使圆形部分旋转或摆动或往复运动。 电池位于中空部分内,为电机供电。 开关可操作地连接到电动机以提供牙刷的瞬时和连续的操作。 蜗轮和一对踏齿齿轮位于中空部分。 马达可操作地连接到蜗轮,并且步进齿轮可操作地连接到蜗轮和彼此。 其中一个阶梯齿轮相对于细长主体部分的纵向轴线偏移。 轴,其可操作地连接到偏移步进齿轮,并连接到第二端到圆形部分。 或者,牙刷包括多个齿轮和旋转臂,其以旋转的,摆动的或往复的方式移动刷头移动部分。

    • A coin handling and sorting device includes a plurality of coin handling modules which are interconnectable by a user, as desired, to define a coin travel path. Each module is easily assembled by a user without use of tools. To facilitate assembly, bases, gears, retaining clips, and other components of different coin handling modules are interchangeable. The housing and other components of each module are assembled using a plurality of C-clips. Each module is typically manually operated to increase a user's interaction with the device. A clutch mechanism prevents accidental reverse operation of each module by a user. To facilitate interconnection of coin handling modules in any desired order, each has an inlet at a common height with other coin module inlets and an outlet at a common height with other coin module outlets. Each module also utilizes identical interchangeable modified spur/bevel gears that are shaped to accommodate co-planar engagement or angular displacement between engaged pairs. A coin connector interconnects the modules and includes a ramp in its inlet to flip coins onto their edges so that they roll to a downstream module. The connectors are pivotable relative to the modules to allow for varied placement of the modules and to facilitate construction of an endless loop coin travel path.
    • 硬币处理和分拣装置包括多个硬币处理模块,可根据需要由使用者互连以形成硬币行进路径。 每个模块都可以轻松地由用户组装而不使用工具。 为了便于组装,基座,齿轮,固定夹和不同硬币处理模块的其他部件是可互换的。 每个模块的外壳和其他部件使用多个C形夹组装。 每个模块通常手动操作以增加用户与设备的交互。 离合器机构防止用户意外地反向操作各个模块。 为了便于以任何期望的顺序连接硬币处理模块,每个入口与其他硬币模块入口处于共同的高度,并且与其他硬币模块出口处于与公共高度的出口。 每个模块还使用相同的可互换的改进的正齿轮/锥齿轮,其被成形为适应接合对之间的共面接合或角位移。 硬币连接器将模块互连,并在其入口中包括一个斜坡,以将硬币翻转到它们的边缘上,使得它们滚动到下游模块。 连接器相对于模块可枢转,以允许模块的变化放置并且便于无限循环硬币行进路径的构造。
