Abstract
The invention relates to a universally applicable detachable magnet holder with a fixed magnet and an opposite-lying magnet which can rotate about a point of rotation and which is provided with magnet pole surfaces, wherein each magnet pole surface comprises at least two poles which, when closed, attract each other and which, when open, repel each other once the rotatable magnet has been rotated by means of an actuation device. According to the invention, a distance element (7), made of a non-ferromagnetic material, is fixed to one of the magnet pole surfaces, whereby the bearing surface on the opposite magnet pole surface is a maximum ⅓ of the surface and a centering engaging device (10a, 10b; 11) is arranged in the vicinity of the magnet poles in order to receive magnetic sheer forces.
Claims10
A magnet holder, comprising:
- a fixed first pair of magnets having a magnet pole surface defined by two poles;
- a second pair of magnets having a magnet pole surface defined by two poles, the second pair of magnets being rotatable about a pivot for movement between an open position in which the poles of the first and second pairs of magnets are positioned to repel one another, and a closed state in which the poles of the first and second pairs of magnets are positioned to attract one another;
- an actuation device for rotating the second pair of magnets to assume the open position;
- a distance element made of a non-ferromagnetic material and arranged on one of the magnet pole surfaces of the first and second pairs of magnets, the distance element being constituted to prevent directly confronting magnet pole surfaces of the first and second pairs of magnets from contacting each other, the distance element being a cylindrical protection which is located between the two poles on the magnet pole surface of the associated pair of magnets and extends from the magnet pole surface of the associated pair of magnets in a direction toward the magnet pole surface of the other pair of magnets;
- and
- a centering engaging device for absorbing magnetic shear forces in vicinity of the magnet pole surfaces of the first and second pairs of magnets.
