Abstract
An adhesive for bonding items includes magnetic particles dispersed therein. Removal is enhanced by applying varying magnetic fields near the adhesive. Magnetic locking elements are biased to engage a catch portion. Removal is effected by urging the magnetic elements out of the catch portion by application of magnetic fields of opposite polarity.
Claims18
A system for the non-destructive adhesion and separation of items comprising:
- an adhesive medium containing a plurality of magnetic particles dispersed therein;
- and
- a magnetic field generator for assisting in release of said adhesive medium from the items;
- and
- at least two arms carrying said magnetic field generator on at least one of said arms, wherein said arms are adapted for contacting at least one of the items and exerting pressure thereagainst so as to form a clamping device.
A system for the non-destructive adhesion and separation of items comprising:
- an adhesive medium containing a plurality of magnetic particles dispersed therein;
- a magnetic field generator for assisting in release of said adhesive medium from the items;
- at least one arm carrying said magnetic field generator thereon, wherein said arm is adapted to be positioned in a substantially close proximity to at least one of the items that are bonded together by said magnetic adhesive medium;
- and
- a vibrator to vibrate said at least one arm.
A method for the non-destructive bonding and separation of surfaces comprising the steps of:
- bonding together at least two surfaces utilizing an adhesion medium with a plurality of magnetic particles dispersed therein;
- positioning at least one magnetic field of oscillating polarity in a substantially close proximity to said bonded surfaces,
- thereby causing movement of the magnetic particles in the adhesive medium so as to aid in the non-destructive separation of the surfaces,
- wherein said surfaces to be bonded together comprise prosthodontic devices.
A method for the non-destructive bonding and separation of surfaces comprising the steps of:
- bonding together at least two surfaces utilizing an adhesion medium with a plurality of magnetic particles dispersed therein;
- positioning at least one magnetic field of oscillating polarity in a substantially close proximity to said bonded surfaces,
- thereby causing movement of the magnetic particles in the adhesive medium so as to aid in the non-destructive separation of the surfaces,
- wherein said positioning step further comprises the steps of:
- clamping an apparatus comprising at least two arms with oscillating magnetic fields generators thereon adjacent the bonded surface to be separated;
- activating said oscillating magnetic fields;
- vibrating said surfaces to aid the separation of the surfaces;
- and
- manipulating the clamping apparatus to further aid in the non-destructive separation of said surfaces.
A prosthodontic magnetic locking device comprising:
- a first surface with at least one biased magnetic arm having a first profile wherein said first surface is a first prosthodontic device adapted to be anchored in a mouth;
- and
- a second surface with at least one region with a second profile corresponding to said profile of the biased arm wherein said second surface is a removable prosthodontic device, and
- wherein said magnetic arm is biased so as to abut said first profile to said second profile to prevent said first surface from moving relative to said second surface.
The prosthodontic magnetic locking device of claim wherein said magnetic spring activated arms of the first surface are oriented approximately 180° apart.
A system for removably locking at least two elements together comprising:
- a first surface defined in a first of said at least two elements comprising at least one magnetic spring activated arm having a first profile;
- a second surface defined in a second of said at least two elements comprising at least one receiver corresponding to said first profile of the spring activated arm;
- and
- an unlocking device comprising at least one magnet,
- wherein said arm is adapted to engage said receiver so as to lock said first surface and said second surface together, and to disengage from said receiver in response to said unlocking device,
- wherein said elements to be removably locked together are prosthodontic devices.
A method for the non-destructive locking and non-destructive separation of two surfaces comprising the steps of:
- engaging a first surface with a magnetic spring activated arm having a profile with a corresponding detent on the second surface matching said profile of the spring activated arm, wherein said detent receives said arm so as to lock the surfaces from moving relative to each other;
- positioning at least one adjustable arm with a magnet attached thereon in a substantially close proximity to the locked surfaces, thereby urging said magnetic arm to disengage from said detent;
- and
- physically separating the surfaces,
- wherein said surfaces comprise portions of prosthodontic devices.
