Definitions

  • This disclosure relates generally to internal side edges, or side rails, for mattresses and, more specifically, to side rails for mattresses that may be used with adjustable beds. Even more specifically, this disclosure relates to side rails with main bodies that impart lateral structure to a mattress of which they are a part and compressible inserts that facilitate adjustment of the mattress while maximizing contact between a bottom of the mattress and an upper supporting surface of an adjustable bedframe. This disclosure also relates to mattresses, to adjustable beds, and to associated methods.
  • Adjustable beds provide for adjustment of the mattresses thereon and of each individual laying on the mattress.
  • An adjustable bed typically bends at two or more locations across its width to provide three sections that may be oriented for a variety of purposes.
  • an upper, or head, section of a mattress on an adjustable bed may be oriented to position an individual's head and back in a somewhat upright orientation, in more reclined orientations, or in a substantially horizontal orientation.
  • a lower, or foot, section of a mattress on an adjustable bed may be oriented to position an individual's feet between inclined, horizontal, and reclined orientations.
  • An intermediate section of the mattress on an adjustable bed may provide a transition between the head section and the foot section.
  • adjustable beds have found wide use in hospitals, care centers, and at other locations where individuals may need assistance in sitting up as they convalesce, where it may be desirable to occasionally change an individual's orientation as he or she lays in bed, or for other purposes.
  • Individuals also use adjustable beds at home, as they many people enjoy laying in non-flat orientations as they rest or sleep.
  • adjustable mattresses to provide certain additional benefits in helping them obtain a good night's rest, as well as health benefits, including, without limitation, the ability to improve breathing during sleep (e.g., by elevating the individual's head, neck, and back, etc.).
  • the side rails of the mattress are compressed at locations where the top of the mattress is bent concavely and stretched at locations where the top of the mattress is bent convexly.
  • Conventional mattresses resist such bending, compression, and stretching somewhat.
  • the bottom of a conventional mattress usually does not conform well to the upper supporting surface of an adjustable bedframe, particularly at corners where the upper supporting surface of the adjustable bedframe is bent concavely, where the bottom of the mattress remains suspended above the concavely bent upper supporting surface of the adjustable bedframe.
  • a side rail of an adjustable mattress has a configuration that enables its bottom edge and, thus, a bottom of a mattress of which it is a part, to conform to bends in an upper supporting surface of an adjustable bedframe.
  • a side rail according to this disclosure may include a main body with at least one upper recess and at least one lower recess, an upper insert within the at least one upper recess, and a lower insert within the at least one lower recess.
  • the side rail may include a plurality of upper recesses and corresponding upper inserts and/or a plurality of lower recesses and corresponding lower inserts.
  • Each upper recess may extend downwardly into a top edge of the main body, partially into the height of the main body, and across an entirety of a width of the main body.
  • Each lower recess may extend upwardly into a bottom edge of the main body, partially into the height of the main body, and across an entirety of a width of the main body.
  • an upper recess may have the shape of a triangular prism, a substantially triangular prism (accounting for more radiused or truncated corners, curvatures in surfaces, etc.), a trapezoidal prism, a substantially trapezoidal prism (accounting for more radiused or truncated corners, curvatures in surfaces, etc.), or the like.
  • a lower recess may have the shape of a triangular prism, a substantially triangular prism (accounting for more radiused or truncated corners, curvatures in surfaces, etc.), a trapezoidal prism, a substantially trapezoidal prism (accounting for more radiused or truncated corners, curvatures in surfaces, etc.), a rectangular prism, a substantially rectangular prism (accounting for more radiused or truncated corners, curvatures in surfaces, etc.), or the like.
  • each upper recess and each lower recess in the main body of a side rail may enable the upper recess and/or lower recess to accommodate bending of a mattress of which the side rail is a part, as well as enable a bottom of the mattress to maintain optimal contact with an upper supporting surface of an adjustable bedframe that carries the mattress. More specifically, each upper recess may be located at a position where an upper supporting surface of the adjustable bedframe and, thus, a top of a mattress thereon are expected to be bent at a concave angle. Each lower recess may be located at a position where the upper supporting surface of the adjustable bedframe and the top of the mattress thereon are expected to be bent at a convex angle.
  • the main body may comprise a material having a rigidity that imparts the side rail with sufficient structural integrity to laterally support a remainder of the mattress of which the side rail is a part.
  • the material of the main body may also be compressible to prevent it from detracting from the overall compressibility and comfort provided by the mattress of which the side rail is a part.
  • An upper insert may be provided in each upper recess of the side rail, while a lower insert may be provided in each lower recess of the side rail.
  • Each upper insert may substantially fill its corresponding upper recess.
  • each upper insert may have a shape or configuration that complements, is the same as, or is substantially the same as a shape or configuration of the upper recess in which the upper insert is positioned.
  • Each upper insert may be secured within its corresponding upper recess in a suitable manner (e.g., with a suitable cement or other adhesive material, etc.).
  • Each lower insert may substantially fill its corresponding lower recess.
  • each lower insert may have a shape or configuration that complements, is the same as, or is substantially the same as a shape or configuration of the lower recess in which the lower insert is positioned.
  • Each lower insert may be secured within its corresponding lower recess in a suitable manner (e.g., with a suitable cement or other adhesive material, etc.).
  • a shape of each upper insert and each lower insert and a material from which each upper insert and each lower insert is formed may enables the side rail to readily flex when the mattress of which it is a part is bent in a corresponding direction.
  • the shape and material of each upper insert may enable the side rail to readily flex when a top of the mattress is bent concavely at a location where the upper insert is located.
  • the shape and material of each lower insert may enable the side rail to readily flex when a top of the mattress is bent convexly at a location where the lower insert is located.
  • each upper insert may be a triangular prism, a substantially triangular prism, or the like
  • shape of each lower insert may be a triangular prism, a substantially triangular prism, a trapezoidal prism, a substantially trapezoidal prism, a rectangular prism, a substantially rectangular prism, or the like.
  • each upper insert and each lower insert may be readily compressible, but have sufficient rigidity to impart the side rail with acceptable structural integrity.
  • each upper insert and each lower insert may comprise a compressible, resilient material.
  • the compressible, resilient material may comprise a foam.
  • this disclosure includes mattresses that include side rails according to this disclosure.
  • the side rails of such a mattress may, along with a base, a head rail, and a foot rail, define a foundation for a cushioning element of the mattress. More specifically, the elements of the foundation may define a receptacle for the cushioning element.
  • the cushioning element may comprise coil springs, pressurizable bladders, memory foam, or any other suitable cushioning element for a mattress, or a combination of cushioning elements.
  • such a mattress may include a gel cushion, such as those disclosed by U.S. Pat. Nos. 7,060,213, 7,076,822, and 8,919,750, the entire disclosures of which are hereby incorporated herein.
  • a gel cushion may include a plurality of resiliently compressible interconnected or intersecting walls defining an array of interconnected, resiliently buckling columns, with a void in each column. Stated another way, the interconnected or intersecting walls may define an array of hollow columns, or voids.
  • Such a gel cushion may be formed from any of a variety of compressible, resilient materials, including cushioning foams and elastomeric materials, such as the extended A B A triblock copolymers disclosed by U.S. Pat. Nos. 6,413,458, 6,797,765, and 7,964,664, the entire disclosures of which are hereby incorporated herein.
