Background Art Hinges are used everywhere in our daily lives. You can find them in car armrests, navigation, automobile televisions, furniture, doors, pianos, desks, closets, windows, shower booths, screens, ceilings, and many other architectural structures. The most common types of hinges are usually attached to objects by using nails, pins, screws, bolts, soldering or other bonding applications/elements or materials. Naturally, those hinges do not look attractive and it was never easy to detach them once they were fixed onto objects. It is highly desirable, therefore, that we develop not only a good-looking but also easy-to-detach, user-friendly hinge system.

Disclosure of invention The technical challenge of this invention is to meet the above mentioned requirements, which is as follow. The structurally central hinge pivot (10) and the hinge main body (1) (or the flexible attachment to the pivot) are set to combine with each other using magnetic energy, which is inserted correspondingly inside the pivot (10) and the L-shaped main body (1). The main body, then, is attached to an object that requires hinges. The magnetic energy, thus, enables the main body (1) to permit a turning movement along the central pivot (10).

As the detachable magnetic hinge system always works as a body with any objects that require hinges, it is almost invisible and, therefore, is attractive looking. It is also efficient because it has temporarily detachable benefits at any time for convenience. The more efficient and economical benefits of D. M. H. S. applied to various equipment used in industry and our daily lives are twofold: We can have more practical and attractive looking daily goods with this new invention. Therefore, it is an invention that is economically rewarding.

The structure of the detachable magnetic hinge system and how it works is as follows.

As you can see from figures one and two, the detachable magnetic hinge system (A) consists largely of two major parts, the hinge's main body (1) and the hinge pivot (10). Magnetic elements or materials equivalent to that are tightly inserted as a component in the middle of the L-shaped main body's two inner sides. In the same way, them-shaped (or square shaped) pivot has its own magnetic elements inserted in the middle of its four sides so that, when the two parts join, their inserted magnetic elements would match completely. Therefore, the main body (1) usually has two inserted magnetic elements (m1, m2) while the pivot (10) has four (g1, g2, g3, g4), so that the two parts would pull each other together due to the opposite polarization of the two magnets. The strength and number of the magnetic elements inserted will depend on the intensity of and purpose of the structure holding the magnetic elements.

The above paragraph outlined the structure of the detachable magnetic hinge system (A). In the structure of the magnetic elements in the pivot (g1, g2) combined with those in the main body (m1, m2), when a turning movement is applied and if that force is enough to cause the detachment of the first magnetic combination in clockwise order, the magnetic elements in the main body (m1, m2) are separated from the earlier combination of g1 and g2 to make the next combination in order with g4 and g3. By repeating the movement according to the structure of the object, the magnetic elements in the main body (m1, m2) makes alternate combinations with its counterparts in the central pivot (g1, g2, g3, g4), serving as a hinge on every turning movement.

Figures three and four, in turn, show how the detachable magnetic hinge system is actually utilized. To explain how the detachable magnetic hinge system works between two tables, for each labeled table (20) and supporting table (30) in figure three, the central pivot (10) is attached to one side of the table (20) and the main body (1) to the other corresponding side of the supporting table (30).

When use of the supporting table is not required, the magnetic elements (m3, m4) in the main body (1) attached previously to the supporting table (30), can be put to combine with the corresponding magnetic elements (g6, g5) in the central pivot (10) attached to the table (20), so that the supporting table (30) could be placed along the table's (20) legs (21). When it is necessary to use two tables (20,30) side by side, the magnetically combined supporting table (30) is turned toward the table (20) 's upper side and the magnetic elements (m3, m4) in the main body ( (1), attached to the supporting table (30) ) subsequently move toward the next corresponding magnetic elements (g6, g7) in the central pivot ( (10), attached to the table (20) ) until the two tables are set together to function as one. The magnetic features of the invention further allows the supporting table (30) holding the main body (1) to be completely detached from the table (20) if necessary.

Likewise, this invention could also serve as door hinges, one of the most commonly used types of hinges. In figure four, the central pivot (10) is set near a window's or a door (d) 's axis of swing and the main body (1) is placed on both sides where the door (d) is located. To serve as an ideal door, the magnetic elements in the central pivot (g8, g9, g10), which were attached previously to the door (d), combine with the corresponding magnetic elements in the main body (m5, m6) intended to match the central pivot (10) on both sides. In other words, the door (d) can stay closed because the magnetic elements in the central pivot (g9, g 10) attached to the door (d) combine with the corresponding magnetic elements in the main body (m5, m6) attached on both sides. If a certain amount of force is applied to open the door (d), the earlier combination gives way to a new magnetic combination in which the next magnetic element pair in the central pivot (g8, g9), which is already fixed on the door (d), makes a new combination with its counterparts in the main body (m5, m6) on both sides, thus keeping the door open.

As was demonstrated in the above passage, by applying this invention to the various objects that use hinges in industry and our daily lives, prospective users can expect that the detachable magnetic hinge system will always work as a body with any objects that hinge on it without any particular attachment body and that this new device well exceeds the span of use we have known for the existing hinges thanks to its easy and efficient on-to-off or off-to-on changes as required.
