CA 2502783

A mattress with a border rod assembly (12) and at least one central spring core(18) is described. The border rod assembly can be manufactured as a unitary member or can be formed from individual border rods (26, 38, 40, 44, 46) and corner pieces (24) that fit together to create a contiguous border around and attached to a central mattress spring core (18). At least one of the individual border rods (38, 44, 46) includes a resilient, polymer material that can be reinforced. Border rod assemblies serve a dual purpose in mattress construction, providing both a frame to which fabrics and foams may be attached and a support structure for the central spring core. Using resilient polymer materials for the border rods allows the mattress to be used interchangeably with adjustable and non-adjustable foundations, and to be transported around obstacles, while retaining the desirable structural aspects of standard steel border rod mattresses.

Cette invention concerne un matelas comportant un ensemble tringle latérale et au moins une âme faite de ressorts. L'ensemble tringle latérale peut être fabriqué d'une seule pièce ou au moyen de tringles latérales distinctes et de pièces d'angle qui, une fois assemblées, créent une limite continue autour de âme de ressort à laquelle elles sont fixées. Une au moins des tiges latérales individuelles comprend un matériau polymère souple pouvant être renforcé. Les ensembles tige latérale répondent à une double fonction dans la réalisation du matelas: constituer un cadre auquel les parties en tissu et en mousse peuvent être fixées, et former un structure porteuse pour âme de ressorts. L'emploi de matériaux polymères souples pour les tiges latérales permet d'utiliser le matelas indifféremment avec des socles réglages et non réglables, et de le transporter entre des obstacles tout en lui conservant les aspects structuraux de matelas classiques à tringles latérales en acier.
