    • A shelf support system includes a sleeve or wedge member and a collar adapted to be secured to a generally cylindrical support post, that is one that is circular when viewed in radial cross-section. The sleeve has an inner surface that is configured to embrace the support post and an outer surface formed with a first axially outwardly inclined wedge portion and at least one second axially outwardly inclined wedge portion that, when viewed in such radial cross-section, extends at an angle to the first portion. Additionally, the collar is adapted to be secured to a member to be supported and to embrace the sleeve. The collar has a first wedge surface formed to mate with the first portion of the outer surface of the sleeve and at least one second wedge surface formed to mate with the second portion of the outer surface of the sleeve. Thus, when the sleeve embraces the post and the collar embraces the sleeve, axial loading of the collar in one direction causes the first wedge surface to mate with the first portion of the outer surface of the sleeve and the second wedge surface to mate with the second portion of the outer surface of the sleeve, thereby urging the sleeve toward the post in at least two generally radial directions.
    • 搁板支撑系统包括套筒或楔形构件以及适于固定到大致圆柱形支撑柱的套环,即当以径向横截面观察时为圆形支撑柱。 套筒具有内表面,其被构造成包围支撑柱和形成有第一轴向向外倾斜的楔形部分的外表面和至少一个第二轴向向外倾斜的楔形部分,当在该径向横截面中观察时,该部分以 与第一部分成一角度。 此外,套环适于被固定到待支撑的构件并且包围套筒。 套环具有形成为与套筒的外表面的第一部分配合的第一楔形表面和形成为与套筒的外表面的第二部分配合的至少一个第二楔形表面。 因此,当套筒包围柱子并且套环包围套筒时,套环在一个方向上的轴向加载使得第一楔形表面与套筒的外表面的第一部分配合,并且第二楔形表面与 从而在套筒的外表面的第二部分中以至少两个大致径向的方向将套筒推向柱。

    • A banquet cart including a cabinet, a plurality of chimneys, an information center, and releasably lockable swivel casters. The plurality of chimneys are positioned inside the cabinet at different corners of the cabinet. The information center includes at least two of (a) a thermometer display indicating the temperature inside of the cabinet; (b) a display indicating time information from a programmable timer; and (c) an information board for displaying text. The releasably locking swivel casters are unlocked to allow swivel action of the casters when a user actuates a foot-operable lever at the front of the cabinet, and are locked when the user releases the lever and the casters are rotated to a predetermined position.
    • 一种宴会车,包括橱柜,多个烟囱,信息中心和可释放地锁定的转脚轮。 多个烟囱位于橱柜的不同角落的柜内。 信息中心至少包括两个(a)温度计显示器,指示机柜内部的温度; (b)显示来自可编程定时器的时间信息的显示; 和(c)显示文本的信息板。 当用户致动在机柜前部的可操作的杠杆并且当用户释放杠杆并且脚轮旋转到预定位置时,可释放地锁定的旋转脚轮被解锁以允许脚轮的旋转动作。
