Title
(EN) MULTI-MATERIAL STRUCTURE AND FORMING OF A LUGGAGE CASE
(FR) STRUCTURE MULTI-MATÉRIAU ET MISE EN FORME D'UNE VALISE
Abstract
(EN)
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.

La présente invention se rapporte à une coque de valise qui peut être formée lors d'une étape de moulage. La coque de valise peut comprendre une couche externe formée à partir d'un matériau plus souple, et une armature formant squelette formée à partir d'un matériau plus dur. L'armature formant squelette peut supporter la couche externe. Une armature de base peut être raccordée à la couche externe et à l'armature formant squelette. L'armature de base peut supporter une poignée télescopique et des roues. Une couche de mousse peut être positionnée entre l'armature formant squelette et la couche externe. Les surfaces internes de l'armature formant squelette et de la couche de mousse peuvent être sensiblement coplanaires. La couche externe et l'armature formant squelette peuvent être unies lors d'une opération de pressage ou de moulage. Pendant l'opération de pressage ou de moulage, la coque peut également être formée. L'armature de base ou la couche de mousse peut également être raccordée à la couche externe et au squelette lors de l'opération de pressage ou de moulage.
