    摘要： A stop assembly for limiting relative rotation comprising inner and outer coaxial members relatively rotatable but longitudinally fixed with respect to each other. The outer member at least partially surrounds the inner member and is at least partially radially spaced therefrom so that an elongate annular space is formed between the members. A first stop surface is provided at one end of the annular space facing axially inwardly. A stop nut is disposed in the annular space coaxial therewith. The nut has a radial split therethrough. The nut is rotatable and longitudinally movable with respect to one of the members and longitudinally movable but not rotatable with respect to the other member. The nut further includes a second stop surface at one end opposed to the first stop surface. One of the stop surfaces inclueds a stop area engageable with the other stop surface adjacent the trailing side of the split, as the nut is advanced toward the first stop surface, with the remainder of the one stop surface spaced from the other stop surface.

    摘要翻译： 用于限制相对旋转的止动组件，其包括相对可旋转但相对于彼此纵向固定的内部和外部同轴构件。 外部构件至少部分地围绕内部构件并且至少部分地径向间隔开，使得在构件之间形成细长的环形空间。 第一止动表面设置在面向轴向内侧的环形空间的一端。 止动螺母设置在与其同轴的环形空间中。 螺母具有径向分开。 螺母是可旋转的并可相对于其中一个构件纵向移动，并可相对于另一个构件纵向移动但不能旋转。 螺母还包括在与第一止动表面相对的一端的第二止动表面。 当螺母朝向第一止动表面前进时，其中一个停止表面包括一个止动区域，该停止区域可与邻近分离器后侧的另一个停止表面相接合，其中一个止动表面的其余部分与另一个止动表面间隔开。

    摘要： A shelf extender for presenting a product to the purchaser forward of a shelf having a container for holding and displaying the product, the container, in one embodiment, having a rear wall with receiving means to cooperate with a plate of a clamp, the clamp having a pair of spaced arms cantilevered therefrom, the first arm having a fixed clamping surface at the end thereof, the second arm having a cavity having two plates adjacent the free end thereof, a standard size nut in the cavity, an opening in each plate of the cavity, the openings being in general alignment with the nut so that a bolt may pass therethrough, a standard size bolt of another size such that the outside diameter of the bolt is no larger than the inside diameter of the nut, the plates of the cavity being shaped so that the nut is in a first position against one plate and in a second position against the other plate, in the first position of the nut, the nut is normal to the bolt and in the second position of the nut, the nut is canted with respect to the bolt so that at least a portion of the thread of the bolt engages at least a portion of the thread of the nut in threaded engagement whereby in the first position of the nut, the bolt is movable for coarse adjustment and in the second position of the nut, the bolt is movable for fine adjustment, a clamping surface at the end of the bolt to permit the clamp to rigidly engage the shelf and thereby hold the shelf extender firmly in place.In another embodiment, the clamp is a part of the end piece of the shelf extender and there are two such end clamps utilized to support the shelf extender. A quick release mechanism for the clamp may be provided to facilitate application of the shelf extender to a shelf and its removal therefrom.
