Abstract
Internal mattress wall structures interlockingly engageable with mattress innerspring assemblies provide a structurally integrated resilient mattress support edge to which the mattress padding and upholstery is integrally attached. The wall structures include a main body section with a vertically oriented wall surface and a plurality of parallel flanges which mechanically engage the innerspring assembly by compression fit between the intermediate and terminal convolutions of the perimetrical coils of the innerspring assembly. Corner structures contiguous with side and end wall structures form a contiguous smooth side wall with support characteristics comparable to an innerspring assembly.
Claims22
An internal mattress wall structure interlockingly engageable with coils of a mattress innerspring assembly to serve as a resilient internal structural component of a mattress, the wall structure comprising:
- a main body section having a generally planar wall surface, top and bottom surfaces intersecting the wall surface, a plurality of parallel flanges extending laterally from the main body section away from the wall surface and adapted to be inserted between convolutions of perimetrical coils of an innerspring assembly, each of the flanges being spaced apart from adjacent flanges and having terminal sections adapted for mechanical engagement with convolutions of perimetrical coils of an innerspring assembly, a ridge rising from the top and bottom surfaces at a point laterally inward from the wall surface, the planar wall surface of the wall structure is adapted to be positioned at a perimeter of an innerspring assembly whereat the ridge on the top and bottom surfaces of the main body is positioned and adapted to be partially overlapped by coils of a mattress innerspring assembly such that the ridge is positioned inwardly of an outer extent of the perimetrical coils, and the wall surface is adapted to extend at least from a top of the innerspring assembly to a bottom of the innerspring assembly to serve as a structural wall of a mattress.
A mattress comprising:
- a mattress innerspring assembly having a plurality of interconnected coils arranged in generally parallel rows, and perimetrical coils to define a generally rectilinear innerspring assembly,
- an internal mattress wall structure comprising a main body section having a planar wall surface, top and bottom surfaces generally perpendicular to the wall surface, a ridge extending from the top and bottom surfaces, and a plurality of parallel flanges extending laterally from the main body section opposite the wall surface, the flanges being spaced apart and having terminal sections mechanically engaged with perimetrical coils of the innerspring assembly,
- the internal mattress wall structure interlockingly engaged with convolutions of the perimetrical coils of the mattress innerspring assembly by insertion of the wall structure flanges and the ridges between convolutions of the perimetrical coils, terminal convolutions of the perimetrical coils contacting and overlapping the ridges such that the ridge is positioned inwardly of an outer extent of the perimetrical coils, the wall structure thus positioned so that the planar wall surface is positioned about a perimeter of the innerspring assembly to define an internal perimeter of the mattress, and extends at least from a top of the innerspring assembly to a bottom of the innerspring assembly to form internal top and bottom edges of the mattress, and
- mattress padding and upholstery material overlying the innerspring assembly and the internal mattress wall structure and attached directly to the internal mattress wall structure.

A one-sided mattress having a single padded sleeping surface and a generally flat bottom surface, the mattress comprising:
- a mattress innerspring assembly having a plurality of interconnected coils arranged in generally parallel rows, an upper and lower support surface, and perimetrical coils to define a generally rectilinear innerspring assembly,
- an internal mattress wall structure comprising a main body section having a planar wall surface, top and bottom surfaces generally perpendicular to the wall surface, a ridge extending from the top and bottom surfaces, and a plurality of parallel flanges extending laterally from the main body section opposite the wall surface, the flanges being spaced apart and having terminal sections mechanically engaged with perimetrical coils of the innerspring assembly,
- the internal mattress wall structure interlockingly engaged with convolutions of the perimetrical coils of the mattress innerspring assembly by insertion of the wall structure flanges and the ridges between convolutions of the perimetrical coils, terminal convolutions of the perimetrical coils overlapping the ridges such that the ridge is positioned inwardly of an outer extent of the perimetrical coils, the wall structure thus positioned so that the planar wall surface is positioned about a perimeter of the innerspring assembly to define an internal perimeter of the mattress, and extends at least from the top of the innerspring assembly to the bottom of the innerspring assembly to form internal top and bottom edges of the mattress, and
- mattress padding and upholstery material overlying the top surface of the innerspring assembly and the internal mattress wall structure and attached directly to the internal mattress wall structure to provide a single padded sleeping surface, and mattress upholstery material closely attached to the bottom surface of the wall structure and the innerspring assembly to form a generally flat mattress bottom.

An internal mattress wall structure interlockingly engageable with coils of a mattress innerspring assembly to serve as a resilient internal structural component of a mattress, the wall structure comprising:
- a main body section having a generally planar wall surface, top and bottom surfaces intersecting the wall surface, a plurality of parallel flanges extending laterally from the main body section away from the wall surface and adapted to be inserted between convolutions of perimetrical coils of an innerspring assembly, each of the flanges being spaced apart from adjacent flanges and having terminal sections adapted for mechanical engagement with convolutions of perimetrical coils of an innerspring assembly, radiused cavities between the spaced apart flanges, the flanges being tapered to generally conform to a helical angle of innerspring assembly coils, wherein a cross-sectional configuration of the terminal sections of the flanges is generally circular, and the planar wall surface of the wall structure adapted to be positioned at a perimeter of an innerspring assembly with the flanges inserted between convolutions of the perimetrical coils, the terminal sections of the flanges positioned generally within the perimetrical coils, and portions of the convolutions of the perimetrical coils between the flanges.
