Definitions

  • the present invention relates generally to fasteners and, more particularly, to magnetic fasteners such as magnetic clasps, buckles and magnetic strap or belt fasteners. More specifically, although of course not solely limiting thereto, the present invention relates to fasteners such as clasps or buckles for use in or with apparel such as a brassiere or the like. This invention also relates to apparel with magnetic fasteners.
  • buttons and fasteners are fastened or secured by mutual interference
  • magnetic attraction between a complementary pair of magnetic fasteners or buttons having complementary or opposite magnetic properties This unique property of magnetic fasteners means that they can be automatically fastened when a detachable pair is in the proximity of each other. At the same time, coupled magnetic buttons can be separated simply by pulling the fasteners or buttons apart and move them away from each other. Also, unlike conventional fasteners such as button assemblies which have to be fastened and released sequentially, an array of magnetic buttons can be simultaneously fastened or released.
  • the above distinctive characteristics find magnetic fasteners particularly useful in circumstances in which the fasteners are required to be done and undone with a single hand and within a short time. For example, magnetic fasteners are useful in costumes for artists or performers who need to change frequently on stage. They are also useful for workers who wear work clothes and vests which may be caught by machinery or moving objects. Clothes or work vests with magnetic buttons provide easy escape to save the wearer from being caught and hurt when the clothes or vests are engaged accidentally.
  • typical magnetic buttons include a pair of complementary parts which are releasably attachable to each other by magnetic attraction.
  • Each of the detachable parts usually includes a magnetic member in slab or tablet form having a top and a bottom magnetic coupling surfaces with the opposite magnetic poles formed on them.
  • the magnetic coupling surfaces are usually interconnected by a continuous peripheral edge which is usually quite thin for aesthetic and styling consideration.
  • the magnetic slabs or tablets are usually
  • the magnetic slabs or tablets are generally enclosed in a magnetic permeable housing which are made, for example, of rubber, Nylon, fabrics, plastics (such as ABS or PVC) or synthetic resin.
  • the housing makes decoration to the magnetic fasteners possible by providing a cover of aesthetic design to the magnetic member which usually has a monotonous and dull metallic appearance as well as providing weathering shield to the magnetic material to slow down or retard undesirable rusting.
  • the enclosure is preferably water- or airtight so that even if the magnet member is oxidized, the enclosure still provides a cosmetic cover to hide the rusted surfaces from the outside, thereby making magnetic buttons suitable for applications in which product presentation and
  • magnetic fasteners are always made with complementary magnetic members having identical shapes and dimensions.
  • the parts will come into substantially automatic alignment once they come into contact and no external help is therefore required in general for the initial contact and the subsequent engagement.
  • magnetic belt or strap fasteners such as strap clasps and buckles should be much more widely used, for example and especially, in applications where the buckles are hard to reach or locate or in applications where the buckles are normally concealed underneath other surfaces during use.
  • One example of such applications is in lingeries or brassieres where the clasps or buckles are usually located at the back or at locations which are not conveniently accessible.
  • Another example is for braces in which some of the fasteners are to be fastened to the back of trousers.
  • the appearance of the fasteners is usually important as their selection is sometimes considered to be representative or reflective of the taste of the user.
  • European Patent Application No.EP923887 discloses a magnetic closure with mutual interlock for bags, knapsacks and items of clothing.
  • This device combines a magnetic closure with a snap-acting closure that contains a pair of male and female parts, h the preferred embodiment, the male element forms a projection that contains a catch for insertion into a slot of the female element for interlocking purposes to prevent natural slippage. Pressing action of the male element allows a user to unlock and separate the two parts.
  • Such a design would effectively require two actions for unlocking of the closure: the pulling apart of the magnet, and the opening of the male and female elements.
  • magnetic buckles having at least some of the afore-mentioned shortcomings overcome or alleviated can be provided so that light, reliable and simple strap fasteners can be provided.
  • strap fasteners should have a low-profile structure which allows decoration to be conveniently and easily added to the buckles to make them more aesthetically pleasing - an important aspect if magnetic buckles are to be widely used in lingerie, fashions or apparel, hi addition, a low-profile structure usually alleviates the risks of damages to the covering or adjacent soft materials.
  • conventional low- profile designs usually mean insufficient magnetic binding force between the magnetic pairs and complicated and additional engagement means are hitherto inevitable for such low-profile designs.
  • fasteners buckles and buttons are used interchangeably for brevity and succinctness to the extent that is appropriate for the context.
  • the strap fastener or buckle which is light, of a simple structure and inexpensive, hi addition, the strap fastener or buckle should have a low-profile build so that it can be easily and conveniently concealed under clothes or other surfaces for aesthetic consideration so that such fasteners can be generally used in the manufacture of under-clothings such as brassieres and lingeries.
