This description is about the detachable magnetic hinge system, an invention that features an L-shaped main body (1) with inserted magnetic elements (m1, m2) in its two inner sides and a central pivot (10) with magnetic elements (g1, g2, g3, g4) inserted on four sides. Each different combination of the pivot (10) with the main body (1), a result of the magnetic elements (m1, m2) in the main body (1) moving towards different elements (g1, g2, g3, g4) in the central pivot (10) (or, in some cases, a result of the magnetic elements (g1, g2, g3, g4) in the central pivot (10) moving towards different elements in the main body (1) as well), that is to say, the various positions the main body (1) takes, determines the various usages and applications of the detachable magnetic hinge system.

Description

Detachable Magnetic Hinge System

The technical Field

The detachable magnetic hinge system or D. M. H. S., an invention

to which this description is committed, introduces a magnetic hinge device

designed for use with two objects that are not attached and yet need a

turning movement between them, thus providing full flexibility in placing

them with increased function and efficiency.

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.

Best Mode for Carrying Out the Invention

The four figures given, which all show the actual circumstances in

which this invention is properly used, are cross-section (Figure 1 ), three

dimensional rendering (Figure 2), and application methods (Figure 3, 4) respectively. 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 D-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 (ml , 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 (ml , nn2), 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 (ml , 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 (ml , 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 bodyO ) 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, mδ) 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, g10) 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, mδ) 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.
