Ventilated Or Permitting Substantial Air Passage Patents (Class 5/724)
  • Patent number: 5699571
    Abstract: An infant bedding apparatus utilizes a mesh sleeping surface and a suspension device adapted to suspend the mesh sleeping surface above an existing sleeping surface of the bed thereby defining an air space between the existing sleeping surface and the mesh sleeping surface. The suspension device is a rigid rectangular frame having connectors, which may be elastomeric, for attachment to the mesh sleeping surface. Tensioners may be attached to the connectors for tensioning the mesh sleeping surface. As a result, the circulation of the fresh air in the area where body contact with the mesh sleeping surface occurs is improved when an infant is sleeping in a face-down or a substantially face-down position.

  • Patent number: 5664273
    Abstract: A mattress assembly designed to allow passive air to flow through the mattress and away from a baby. The mattress assembly includes a lightweight frame member with openings on all four sides and a breathable slip-on mattress cover which fits snugly over the frame. An infant is positioned upon the mattress over the bed frame opening, thereby allowing the air to pass through the breathable mattress cover.

  • Patent number: 5643139
    Abstract: A contoured landing surface system and a method of making thereof are provided. The system matches landing surface or pit density to the force generated by an athlete's descending body to cushion the athlete's fall based on air displacement rather than foam characteristics. The system is designed to compensate for variables such a velocity, mass and surface area at the point of impact by utilizing a multi-layer structure, each layer having a plurality of patterned ridges thereon and a network of air channels therebetween. The ridges and air channels of adjacent layers extend perpendicular to the ridges and air channels of each other. Preferably, the landing surface is constructed using layers of foam having the same density.

  • Patent number: 5607749
    Abstract: An acupressure massaging system includes a platform having an upper surface, and includes an array of intersecting air channels extending therethrough in communication with space external of the pad. An array of spaced, independently flexible nipples extends from the upper surface of the platform, each nipple having an upper distal end and a flexible, accordion-pleated side wall comprised of material having elastic memory and defining an internal air-flow chamber. The air-flow chamber is in fluid communication with the air-flow channels and each nipple is structured and disposed for movement from a biased and normally extended position to a compressed position in response to contact with the skin or clothing of the user.

  • Patent number: 5561876
    Abstract: A mattress like structure is provided which is designed to not only give good support to an infant while sleeping, but may hopefully reduce the possibility of the infant suffocating while sleeping on its stomach. It includes a generally rectangular shaped rigid frame with a resilient, flexible fabric of special construction tightly stretched over the frame to form a top and bottom surface. The fabric is of an open mesh type with relatively large openings to provide excellent air flow to the infant. The non-open area of the fabric is such that it will support the infant in a very comfortable manner without making any creases or lines in the infant's skin. Moreover, the openings, although relatively large are not so large that the infant's fingers can be caught in the openings. The special fabric is constructed in the form of a generally rectangular shaped sleeve closed at one end and provided with a zipper or other closure means about a portion of its perimeter.
