Definitions
- the invention relates to a magnetic clasp, in particular for jewelry, clothing and the like, in which essentially disc-shaped clasp bodies made of magnetizable metal are fastened to the parts to be closed, which are arranged parallel to one another in the closed position and of which at least one is a permanent magnet.
- the one clasp body is cup-shaped and serves to hold a magnet
- the second clasp body applied to the magnet is designed as a circular disk.
- the cup wall is partially raised.
- this requires that the disk-shaped clasp body with its connection point for the piece of jewelry be used very precisely, because otherwise there is the risk of unintentional loosening when a tensile force is exerted in the radial direction over half the circumference of the cup-shaped clasp body.
- the manufacture of a cup-shaped clasp body is also complex, this effort being further increased by the necessary processing of the rim of the cup.
- the invention aims to overcome the disadvantages of to avoid known construction and to create a magnetic scene of the type specified in the introduction, which is secured against unintentional opening with a simple design.
- the magnetic clasp according to the invention is distinguished by the fact that both clasp bodies are designed as ring disks which are open on both sides and which, in the closed position, jointly delimit a passage in which a further body made of magnetizable material with radial play is inserted.
- the further body is preferably a permanent magnet.
- An alternative embodiment of the invention has the features that one of the two clasp bodies is designed as an annular disk which is open on both sides and has a radial slot, and into which the other clasp body designed as a closed disk passes over the slot with the part to be closed is connected, is used in the axial direction with play.
- both clasp bodies are permanent magnets and that the axial magnetization of the inner clasp body in the opposite direction to the axial magnetization of the outer clasp body.
- the permanent magnet or magnets consists or consist of rare earths or an alloy of rare earths.
- FIG. 1 shows a cross section through a first embodiment of the magnetic clasp according to the invention
- 2 shows a top view of the magnetic clasp according to FIG. 1
- FIG. 3 shows a cross section through a second embodiment of the magnetic clasp according to the invention
- FIG. 4 shows a top view of FIG. 3.
- the magnetic clasp has two of the same size , on both sides open washers 1, 2 with a rectangular cross-section.
- the washers 1, 2 consist of permanent magnets, in particular of an alloy of rare earths, and are each connected to one of the parts 3 and 4 to be closed, for example a chain of a piece of jewelry, a piece of clothing, etc.
- the two ring disks 1, 2 are magnetized in the same direction in the axial direction.
- a circular cylindrical permanent magnetic body 5, for example made of the material used for the ring disks 1, 2, is arranged inside the two ring disks 1, 2 with play relative to the disks, and so on. with axial magnetization opposed to the ring disks 1, 2.
- the two can advantageously be connected to the parts 3, 4 to be closed After the body 5 has been inserted, annular disks 1, 2 can no longer be separated from one another by exerting a tensile force on the disks.
- both ring disks 1, 2 need to be a permanent magnet; the other disk can be made of magnetizable material, but does not need to be magnetized itself.
- the closure effect is then of course weaker in each case.
- both ring disks are formed from permanent magnets in the example shown in FIGS. 1 and 2, they can also be arranged on a longer body 5 with axially identical magnetization, as a result of which they are kept at a mutual distance.
- the magnetic clasp is only formed from two parts, etc.
- annular disk 6 with a rectangular cross section forming a clasp body and open on both sides, and a closed annular disk 7 with a rectangular cross section forming the other clasp body, which are arranged in the interior of the annular disk 6 with play in the axial direction and via the slot 6 'with the associated part the piece of jewelry and the like connected is.
- At least one of the two ring disks 6, 7 is a permanent magnet, in particular made of the material already mentioned.
- the other disk is made of a magnetizable material. If both disks are permanent magnets, they are magnetized in opposite directions in the axial direction.
- Disks can be modified in different ways.
- the clasp body can be embedded in sockets which are connected to the parts to be closed.
