Definitions

  • the present invention relates to a cushion, especially to a magnetic levitation cushion being used as a supporting assembly for beds, chairs, sofas and the like.
  • Upholstered furniture like beds, chairs or sofas generally comprise supporting elements, such as springs or latex.
  • a spring-bed offers a level of comfort determined by a number of coils of metal springs and wire diameter of the metal springs installed inside the spring-bed.
  • the springs also affect flexibility and hardness of the spring-bed. Therefore, lying on a very hard or soft spring-bed may chronically injure a person's back and spine and may also cause loss of sleep due to discomfort and even negatively-affect growth of a child's spine.
  • the spring-bed has a lifespan due to metal fatigue and will become too soft for a person's spine.
  • the internal structure of the spring-bed is so complicated that dirt easily accumulates inside and the spring-bed is hard to be dismantled for cleaning the dirt.
  • a latex bed is suitable for lying on.
  • the material of the latex bed has a high density. With bad ventilation, the latex bed will not provide good heat-dissipation and cause discomfort, even heat-rash by excessive perspiration. Besides, latex material of the latex bed will become harder year by year and crumble causing terminal failure.
  • the present invention provides a magnetic levitation cushion to mitigate or obviate the aforementioned problems.
  • the main objective of the present invention is to provide a magnetic levitation cushion that uses permanent magnets to exert repulsive magnetic forces as supporting forces.
  • the magnetic levitation cushion has multiple magnetic levitation devices being assembled with at least one bracket.
  • Each magnetic levitation device has a housing, a fixed magnet, a movable magnet, a shaft and a primary pad.
  • the fixed magnet is mounted securely in the housing.
  • the movable magnet is mounted slidably in the housing and faces the fixed magnet with a same magnetic pole.
  • the shaft is mounted slidably through the housing and has a bottom end attached to the movable magnet.
  • the primary pad is mounted on a top end of the shaft.
  • the cushion is used for upholstered furniture such as chairs, beds and sofas. Since the magnets provide magnetic forces, the cushion does not suffer from metal fatigue or material hardening problems and may be cleaned, rearranged and recycled effectively.
  • a magnetic levitation cushion in accordance with the present invention comprises multiple magnetic levitation devices (1) and at least one bracket (2).
  • Each magnetic levitation device (1) comprises a housing (10), an optional base (11), an optional lid (12), an optional piston (13), a fixed magnet (14), a movable magnet (15), a shaft (16), a primary pad (17), two optional rings (18) and at least one optional suspended magnet (30).
  • the housing (10) has an open top, an open bottom, a top rim and a bottom rim, may be cylindrical or cuboidal and may have multiple protrusions (100), multiple tab holes and at least one bracket mount.
  • the protrusions (100) and the tab holes are formed in the top rim and bottom rim of the housing (10) and may be adjacent to each other.
  • the at least one bracket mount is formed on the housing (10) and may be a protrusion.
  • the base (11) is mounted on the open bottom of the housing (10) and has a top surface, a recess (110) and multiple optional tabs.
  • the recess (110) is formed on the top surface of the base (11).
  • the optional tabs are resilient and protrude radially around the base (11) and respectively extend into a corresponding tab hole of the housing (10).
  • the lid (12) is mounted on the open top of the housing (10) and has a through hole (120) and multiple optional tabs.
  • the through hole (120) is formed through the lid (12) and may be keyed and may be a cross, a polygon or the like.
  • the optional tabs are resilient and protrude radially around the lid (12) and respectively extend into a corresponding tab hole of the housing (10).
  • the piston (13) is mounted slidably inside the housing (10) and has an upper surface, a lower surface, a recess (130) and a shaft mount (131).
  • the recess (130) is formed on the lower surface and opposite to the recess (110) of the base (11).
  • the shaft mount (131) is formed on the upper surface of the piston (13) and may protrude from the upper surface of the piston (13), correspond to and extend into the through hole (120) of the lid (12).
  • the fixed magnet (14) is mounted securely inside the housing (10) and may be mounted in the recess (110) of the base (11).
  • the movable magnet (15) is mounted slidably in the housing (10), faces the fixed magnet (14) with a same magnetic pole to exert repulsion forces to the fixed magnet (14) and may be mounted securely in the recess (130) of the piston (13). The movable magnet (15) then stays apart from the fixed magnet (14) due to the magnetic repulsion forces and is prevented from flipping by the piston (13).
  • the shaft (16) is mounted slidably through the housing and has a bottom end and a top end. The bottom end is attached to the movable magnet (15), extends through the through hole (120) of the lid (12) into the housing (10), and may have a piston mount (160).
  • the piston mount (160) corresponds to and is connected securely to the shaft mount (131) of the piston (13).
  • the primary pad (17) is mounted on the top end of the shaft (16) and may have an upper surface, at least one pad mount (171) and at least one secondary pad (170).
  • the at least one pad mount (171) is formed on upper surface of the primary pad (170).
  • the at least one secondary pad (170) is mounted on the at least one pad mount (171) and may be resilient and comprise multiple wings protruding away from a plane of the at least one secondary pad (170) and has a center, a mounting hole (172) and a fastener (173).
  • the mounting hole (172) is formed through the center of the at least one secondary pad (170).
  • the fastener (173) mounts the at least one secondary pad (170) on the pad mount (171) of the primary pad (17) through the mounting hole (172).
  • each ring (18) may have an inner sidewall, an outer sidewall, at least one slot (180) and at least one bracket mount (181).
  • the slot (180) is formed on the inner sidewall and engages a corresponding protrusion (100) of the housing (10) to fix the ring (18) on the housing (10) and reinforce the housing (10).
  • the at least one bracket mount (181) is formed on the outer sidewall of the ring (18) to allow simple attachment of multiple magnetic levitation devices (1).
  • the at least one optional suspended magnet (30) is mounted slidably between the fixed magnet (14) and the movable magnet (15) inside the housing (10) and may comprise a suspension frame mounted between the housing (10) and the suspended magnet (30) to prevent rotation or flipping thereof.
  • Each ring mount (20) corresponds to and engages the bracket mount (181) of the housing (10), maybe on the ring (18) mounted on the bottom rim or the top rim, or the top and bottom rims of the housing (10). Therefore the magnetic levitation devices (1) are assembled with the bracket (2).
  • the present invention can be used as a supporting structure for upholstered furniture.
  • the magnets (14, 15, 30) are all permanent magnets and will maintain the magnetic repulsion inside the housing (10) for a long time.
  • the upholstered furniture thus has a long lifespan.
