  • Patent number: 8020679
    Abstract: Disclosed is a rotatable foot-wheel used for a luggage trunk, that is provided to a user with a simple & convenient mounting and detaching means, such that in detaching a foot-wheel from a luggage trunk, upon securing a lower half portion element, all the user has to do is to move the step-shaped housing of an upper half portion element outward, so that balls on a ball portion are separated from the step-shaped housing, then rotating the foot-wheel to make it separate, thus achieving the purpose of detaching a rotatable foot-wheel, such that a user may replace worn-out elements by himself. When installing a new element or reinstalling a repaired element, similarly, upon securing a lower half portion element, moving step-shaped housing of an upper half portion element outward, so that balls on the ball portion rejoin with the step-shaped housing, hereby achieving the objective of fixing and re-installing foot-wheels.

  • Patent number: 7866453
    Abstract: The present invention discloses a swivelable trunk wheel assembly, which comprises: a wheel frame, a guide hole, a hollow pivotal shaft, a push rod, a press block, a sleeve pipe, two wheels and two rivets. The sleeve pipe adopts a metallic pipe having a better rigidity, and the inner surface of the sleeve pipe is a smooth surface. Further, the rivets and the sleeve pipe are arranged in the same axis. Thus, the wheels can rotate smoothly without stagnancy. Therefore, the swivelable trunk wheel assembly of the present invention has a better wear resistance and a longer service life. Besides, the present invention uses the push rod to drive the press block to rub the friction portion, and the friction can provide a braking effect on the wheels.
