MULTI-MATERIAL STRUCTURE AND FORMING OF A LUGGAGE CASE

摘要

A luggage case shell may be formed in a molding step. The luggage case shell may including an outer layer formed from a softer material, and a skeletal frame formed from a harder material. The skeletal frame may support the outer layer. A base frame may be joined to the outer layer and the skeletal frame. The base frame may support a telescoping handle and wheels. A foam layer may be positioned between the skeletal frame and the outer layer. Inner surfaces of the skeletal frame and the foam layer may be substantially co-planar. The outer layer and the skeletal frame may be joined in a pressing or molding operation. During the pressing or molding operation, the shell may also be shaped. The base frame or the foam layer may also be joined to the outer layer and the skeletal in the pressing or molding operation.
