Benefits of technology
"The present invention provides a cushion device for the wheel of wheeled luggage to make the wheel luggage operation more comfortable and increase the operation life. The cushion device includes a seat member installed on the bottom edge of the wheel luggage and a buffering member where the wheel is rotatably mounted. The buffering member is hinged to a pin and a helix spring is provided to absorb the shock of the buffering member. The distance between the pin and the spring is longer than the distance between the pin and the axle of the wheel so that the spring will undergo only a fraction of the force exerted on the wheel. This cushion device makes the wheel luggage operation more comfortable and increases the operation life."
Problems solved by technology
Conveniently, each wheel of the wheeled luggage is rotatably and directly mounted to a seat of the luggage by the axle of the wheel without the provision of any shock absorption mechanism and, therefore, it is quite uncomfortable pulling the luggage over a bumpy surface.
A disadvantage of the forgoing design is that the displacement of the wheel's axle is identical to the amount of compression to the springs.

Embodiment Construction
[0013]The followingdescriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
[0014]As shown in FIGS. 1 to 4, a cushion device for the wheeled luggage according to an embodiment of the present invention contains an L-shaped seat member 10 installed to a bottom edge of the wheeled luggage. The seat member 10 has a concaved right-angled triangular section 12 between the two legs of its L-shaped body, thereby forming a right-angled triangular compartment 11 around the corner of the L-shaped seat member 10. The triangular section 12 is provided such that a further concavity, i.e.,...

A cushion device for a wheel of the wheeled luggage contains a seat member for installation to a bottom edge of the wheel luggage. The seat member contains an open compartment having a rotatable pin to a side of the opening of the compartment. The cushion device further contains a buffering member where the wheel of the wheeled luggage is rotatably mounted by the wheel's axle. The buffering member is housed inside the compartment of the seat member and hinged to the pin. A helix spring is provided inside the compartment between the seat member and the buffering member for absorbing the shock of the buffering member. The distance between the pin and the spring is longer than the distance between the pin and the axle of the wheel so that the spring will undergo on;y a fraction of the vibration force exerted on the wheel.
Description
TECHNICAL FIELD OF THE INVENTION[0001]The present inventiongenerally relates to the wheeled luggage, and more particularly to a cushion device for a wheel of the wheeled luggage.DESCRIPTION OF THE PRIOR ART[0002]Wheeled luggage has been a convenient companion for travelers. Usually, an ordinary type of wheeled luggage has a telescoping handle and a pair of wheels provided at a bottom edge of the luggage. By pulling out the telescoping handle and lifting the luggage to rest the weight of the luggage on the wheels, the luggage can be easily pulled and moved around on the wheels, significantly saving the effort of the luggage owner.[0003]Conveniently, each wheel of the wheeled luggage is rotatably and directly mounted to a seat of the luggage by the axle of the wheel without the provision of any shock absorption mechanism and, therefore, it is quite uncomfortable pulling the luggage over a bumpy surface. R.O.C. (Taiwan) Patent No. 540,338 teaches a type of wheeled luggage where two spr...
