Embodiment Construction

[0054] Described here are wheel assemblies for suitcases, especially rotating wheel assemblies, such as soft-shell suitcases, hard-shell suitcases, hybrid suitcases, backpacks, briefcases, computer bags or any luggage box. Each wheel assembly may include a housing for operatively coupling the wheel assembly to the surface of the luggage case, a wheel support rotatably coupled to the housing, and a wheel support rotatably coupled to the wheel support The wheel components. The wheel assembly may further include a friction reducing member to facilitate rotation of the wheel support relative to the wheel housing. The friction reducing member may movably engage the wheel housing at the first bearing surface of the wheel housing. The friction reducing member may movably engage the wheel housing at the second bearing surface of the wheel housing. Each of the first bearing surface and the second bearing surface may substantially define a frustoconical shape. The wheel support is lo...

Abstract

The present invention relates to a wheel assembly (102) for a luggage case and a luggage case. The wheel assembly (102) may include a housing (136) for operatively connecting the wheel assembly (102) to the luggage case. The wheel assembly (102) may also include a wheel support (138) rotatably coupled to the housing (136) and having a first axis of rotation. The wheel support (138) may be coupled to a wheel member (140) having a second axis of rotation. A friction reducing member (142) may be positioned between the housing (136) and the wheel support (138) to facilitate relative movement therebetween. The wheel support (138) may include an underside defining a partially conical shape.

Description

Technical field [0001] The present disclosure generally relates to luggage. More specifically, the present disclosure relates to wheel assemblies for luggage cases. Background technique [0002] Many luggage cases can include wheel assemblies to provide rolling support for the luggage on a supporting surface. An example of such a rolling support includes four rotating wheel assemblies coupled to the bottom of the luggage case. The configuration of four rotating wheels allows the user to roll the luggage laterally in any direction without having to tilt the luggage on a pair of wheels. The rotating wheel assembly generally includes a housing for coupling the wheel assembly to the luggage and a wheel support for rotatably connecting the wheel to the base of the housing so that the wheel rotates about a substantially vertical axis. In order to facilitate the rotation of the wheel support with respect to the base, the wheel assembly may be equipped with a bearing structure, such a...
