可伸缩轮组件

Retractable wheel assembly

US-7503439-B2

用于载体(如行李箱)的可伸缩轮组件,便于推行和收纳。

专利摘要

一种用于载体(100)的可伸缩轮组件(110),其中轮子(120)可转动地安装在整流罩(130)中,整流罩可枢转地设置在壳体上的轮舱(116L, 116R)中。整流罩与包括螺旋弹簧的轮轴组件(140)连接,优选为恒力弹簧(150),其将整流罩偏压至缩回位置。恒力弹簧连接到可伸缩手柄(104),优选通过弹簧接合构件(160),使得拉出可伸缩手柄将整流罩偏压至伸出位置,此时轮子从轮舱中伸出以供使用。

Original abstractA retractable wheel assembly ( 110 ) for a carrier ( 100 ) is disclosed wherein the wheels ( 120 ) are rotatably mounted in cowls ( 130 ), which are pivotably disposed in wheel wells ( 116 L, 116 R) on a housing. The cowls are connected with a cowl axle assembly ( 140 ) that includes a coil spring, preferably a constant force spring ( 150 ) that biases the cowls towards a retracted position. The constant force spring is connected to a retractable handle ( 104 ), preferably with a spring engagement member ( 160 ), such that extending the retractable handle will bias the cowls towards an extended position, wherein the wheels extend out of the wheel wells for use.
