Abstract: The following specification describes a two-wheel caster in which the junctions between parts are camouflaged for improved appearance. Both wheels have a blind hole and are press fit on bushings. The bushings are rotatably secured on the respective end of a common shaft located between the two wheels by means of a respective C-ring engaged in a shaft groove. The shaft is cantilever supported in a radial wall between the wheels with the wall having a peripheral arcuate hood wall formed integral therewith and overlapping a large portion of the wheel periphery. The pintle stem is rotatably secured by means of a C-ring engaged in a stem groove in a boss having a blind hole or recess extending into the radial wall.

Abstract translation: 以下说明书描述了一种两轮脚轮，其中部件之间的接合被伪装以改善外观。 两个轮子都有一个盲孔，并且压配合衬套。 衬套通过与轴槽接合的相应C形环可旋转地固定在位于两个车轮之间的公共轴的相应端部上。 轴是支撑在轮之间的径向壁中的悬臂，其中壁具有与其一体形成的周边弧形罩壁，并与轮周边的大部分重叠。 枢轴杆通过C形环可旋转地固定，该C形环与一个具有延伸到径向壁中的盲孔或凹槽的凸台中的杆槽相啮合。
