    • 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,当从该径向横截面观察时,楔形部分以 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 method of manufacturing a caster includes the step of integrally forming a caster horn having a web portion with a bearing cup and a pair of opposed leg portions. The web portion and the leg portion define a U-shaped, wheel-accomodating space. The bearing cup is disposed on a surface of the web portion opposite from the U-shaped wheel-accommodating space. A first end of a stem is then pressed into a bearing assembly such that the stem is vertically rotatable with respect to the caster horn. The bearing assembly is seated in the bearing cup. The bearing assembly may be secured to the bearing cup by means of a retainer and a plurality of fasteners. The fasteners engage the caster horn, covering the bearing cup while allowing access to a second end of the stem. A wheel is rotatably supported within the U-shaped wheel-accommodating space.
    • 一种制造脚轮的方法包括将具有腹板部分的脚轮喇叭整体地形成为具有轴承杯和一对相对的腿部的步骤。 腹板部分和腿部限定U形的轮子容纳空间。 轴承杯设置在与U形轮容纳空间相对的腹板部分的表面上。 然后将杆的第一端压入轴承组件,使得杆相对于脚轮角可竖直旋转。 轴承组件位于轴承杯中。 轴承组件可以通过保持器和多个紧固件固定到轴承杯。 紧固件接合脚轮角,覆盖轴承杯,同时允许进入杆的第二端。 轮可旋转地支撑在U形轮容纳空间内。
