    Abstract: A caster includes first and second antifriction bearings which respectively have first and second outer race members disposed over and underneath a bearing seat of a fork frame, respectively. The first and second outer race members respectively have first and second smaller rivet holes aligned with a larger rivet hole in the bearing seat along a swivel axis to form a combined rivet hole. A swivel shaft is inserted into the combined rivet hole to form an annular space for receiving a tubular bracing member that is sleeved on the shaft. A point of the shaft is riveted to fasten the second outer race member. The impact force during riveting is transmitted to the head primarily through the bracing member.

    Abstract translation: 脚轮包括分别具有分别设置在叉架的轴承座的上方和下方的第一和第二外圈构件的第一和第二减摩轴承。 第一和第二外圈构件分别具有第一和第二较小的铆钉孔，其沿着旋转轴线与轴承座中的较大的铆钉孔对准以形成组合的铆钉孔。 旋转轴被插入到组合的铆钉孔中以形成用于接收套在轴上的管状支撑构件的环形空间。 轴的一点被铆接以固定第二外圈构件。 铆接中的冲击力主要通过支撑构件传递到头部。

    Abstract: A wheel of a rack consists of a wheel support, a sleeve inserted into a tube of a rack, a supporting member joined to both the sleeve and a top of the wheel support, and a screw projecting from the supporting member and screwed into the sleeve; a step-shaped portion being formed on top of the supporting member to fit with a cavity on the sleeve bottom; a resilient C-shaped ring being fitted around an annular groove of the sleeve to contact an inner side of the tube; the groove being shaped so that a sideways facing portion thereof tapers off towards a lower end; thus, the ring will move to the bigger upper section of the sideways facing annular portion to be pressed against the inner side of the tube with bigger pressure when a downward force is applied on the sleeve.

    Abstract: A chair base includes a rigid base member having a plurality of elongate tubular leg members disposed angularly around and radiating outwardly from a central hub. Each leg member adjacent an outer free end thereof has a hub structure defining a through vertical bore for retaining the pintle of a caster. The hub structure includes coaxially aligned upper and lower sleevelike hub parts which are monolithically and integrally joined to and extruded transversely into the interior of the leg member from the respective top and bottom walls thereof. The pintle-retaining hub structure is formed by a pierce-and-extrude process whereby small pilot openings are initially formed through the respective walls, and the annular wall portion surrounding the respective pilot opening is thereafter transversely extruded to effect forming of the respective hub part. The pierce-and-extrude process for each hub part is, in a preferred process, carried out by a single forming tool.

    Abstract: A hub and wheel assembly enabling the moving direction of wheels of a vehicle to be adjusted instantly as the exerted pushing force changes direction comprises a wheel mount having wheels mounted thereon, and a swivel base assembly mounted on stroller leg. Wheel mount may quickly assemble with and detach from swivel base assembly. A protrusion of wheel mount, inserted into swivel base assembly, includes a circumferential groove having a cavity provided therein such that a spring-biased locking member may releasably engage with cavity for setting movement of wheels in a linear direction. Further, as a deflecting force is applied on the stroller locking member disengages with cavity for allowing wheels to move to left or right. Once the force is released, locking member will instantly return to its normal position to engage with cavity.

    Abstract translation: 随着施加的推力改变方向，能够立即调节车辆的车轮的移动方向的轮毂和车轮组件包括其上安装有车轮的车轮安装件和安装在婴儿车脚上的旋转基座组件。 车轮安装座可以快速组装并从旋转底座组件拆下。 插入旋转基座组件中的轮安装件的突起部包括具有设置在其中的空腔的圆周凹槽，使得弹簧偏置的锁定构件可以与空腔可释放地接合，以将轮子沿线性方向设置。 此外，由于偏转力施加在婴儿车锁定构件上，与空腔脱离以允许车轮向左或向右移动。 一旦力释放，锁定构件将立即返回其正常位置以与空腔接合。
