Definitions

  • the present invention relates to the field of mattresses. More particularly, the invention relates to an inner spring mattress that can readily and economically be provided with varied and enhanced support characteristics.
  • mattress manufacturers design and build different types of mattresses with different characteristics that are comfortable, correct, and suitable for different people. This may have required constructing mattresses with different types of inner spring assemblies, such as inner spring assemblies having different numbers of springs, or different sizes of springs, or made with springs of different materials. It can readily be appreciated that, from the mattress manufacturer's viewpoint, constructing various different types of mattresses can detract from an efficient and economical manufacturing process and can result in higher production costs. For example, in the past, if a mattress manufacturer wanted to produce mattresses having differing characteristics, the manufacturer might have opted to maintain an inventory of different materials, such as different sizes of springs or springs made of different materials. Alternatively, in order to produce mattresses of differing characteristics, a manufacturer may have had to modify the assembly process.
  • a mattress, or similar spring cushion unit of a construction that can be readily and economically modified during the manufacturing process, so as to provide varying properties or characteristics.
  • a mattress and a method for manufacturing a mattress, having an inner spring assembly with a plurality of interconnected individual spring coils and resilient core members located within selected spring coils of the inner spring assembly to impart different support characteristics to the mattress at the location of the core members.
  • FIG. 1 is a perspective view of part of a mattress made in accordance with the teachings of the present invention, with a partial cutaway portion;
  • FIG. 2 is an enlarged perspective view of a single spring unit and core member of the embodiment shown in FIG. 1,
  • FIG. 3 is an elevational view of the spring unit and core member of FIG. 2;
  • FIG. 4 is a schematic plan of an alternative arrangement springs made in accordance with the teachings of the present invention.
  • FIG. 1 there is a portion of a mattress 10 with a portion thereof cutaway.
  • the mattress has a first (or top) side 12, a second (or bottom) side 14.
  • An inner spring assembly 16 is located between one or more layers 17 of padding, foam, netting, mesh, fabric, ticking, coverings, or the like, as is well known in the art.
  • the inner spring assembly 16 is comprised of a plurality of coil springs, e.g. spring 18.
  • the coil springs 18 in the inner spring assembly 16 are arranged in rows and columns in a regular rectangular pattern.
  • the inner spring assembly 16 shown here is may be comprised of identical springs, although springs of differing characteristics could be used.
  • the springs that make up the inner spring assembly 16 are interconnected by cross-verticals 15 with the springs along the perimeter of the mattress also connected to a border wire 19 by a border wire helical 21.
  • the coil springs 18 as well as their assembly into an innerspring unit are well known in the art, and further detail of the same shall be omitted.
  • FIG. 2 there is depicted an individual spring unit 20 that forms part of the inner spring assembly 16 of an embodiment of the present invention.
  • the spring unit 20 includes a spring 18 portion 22 having first end 24 and a second end 26.
  • the spring 18 may be made for instance of spring wire having a diameter of approximately 0.073 inches wound into a helical shape with an inner diameter of approximately 1.6 inches. Other shapes and materials may be utilized for the spring.
  • the core member 28 is a cylinder of resilient material, such as urethane foam, that is positioned inside the convolutions of the coil of the spring 18.
  • the core member 28 is dimensioned so that its length is slightly less than the length of the spring 18 when the spring unit is fixed in place in the innerspring 16.
  • the spring 18 has a height of approximately 5 3/4 inches when installed in the mattress and in an unloaded state, i.e., without a force applied to the mattress top/bottom 12/14.
  • the core member 28 has a length of approximately 5 1/4 inches.
  • the mattress characteristics are initially defined solely by the characteristics of the spring member because the spring unit can be compressed slightly, e.g. 1/2 inch, from its length of 5 3/4 inches to a length of 5 1/4 inches before additional compression is opposed by both the spring unit and the core member. This has the effect that the mattress is firmer where the spring units 20 are located.
  • the diameter of the core member is preferably slightly smaller than the diameter of the intermediate convolutions of the spring 18, so that the coils of the spring can readily move relative to the core member, i.e. to avoid friction between the coils and the core member.
  • the diameter of the core member is preferably slightly smaller than the diameter of the intermediate convolutions of the spring 18 for ease of insertion during the manufacturing process.
  • the inner diameter of the spring portion is approximately 1.6 inches.
  • the diameter of the depicted core member 28 is approximately 1.5 inches.
  • the core member 28 is made of urethane foam having a density of 2 pounds per cubic foot and a compression of 12.0 psi at 50% deformation. Other densities or compressions may be used to impart different characteristics or properties to spring units 20.
  • the core member is solid, although it may be hollow in alternative embodiments. Different materials or construction may be used for the core member, for example, the core member may be made of foam rubber or resilient plastic or an elastomeric material, or the core member may be a pneumatic or hydraulic device, or may be another spring.
  • the present invention can be adapted to readily impart different characteristics to different locations of the mattress. This is accomplished by selecting springs located at the position in the inner spring assembly of the mattress corresponding to the area at which enhanced.firmness is desired. These selected springs can then be readily adapted simply by placing a core member therein to impart greater support, or firmness. If it is preferred to make a mattress with a firm area along the perimeter, the mattress can be manufactured with core members inside each individual spring unit along the perimeter of the inner spring assembly. Alternatively, core members can be positioned only in every other spring unit along the perimeter, or in any other sequence depending on the level of firmness desired. Every other spring (FIG. 1) is presently considered to be the most efficient and economical, however.
  • an inner spring assembly 42 in which core members 28 are fitted in selected springs corresponding generally to the lumbar region of a person using the mattress.
  • the firmness of selected areas can be readily varied during the manufacture of a mattress by the number, location, compression, and length of the core members.
  • similar or identical inner spring assemblies may be used for constructing various models of mattresses each with different degrees of firmness or with different areas of firmness. This has the advantage of providing for a variety of choices of mattresses for the consumer, simplifying and reducing the costs associated with manufacturing mattresses of different construction.
  • the core member is located inside the coil spring portion. This facilitates locating the core member and orienting it in a direction to contribute to the firmness of the mattress.
  • Other alternative arrangements are possible, however, such as placing the core member around the spring, or along its side.
