Description
Title
= Magnetic Wall Decoration Device
Technical Field
= This invention relates to magnetic decoration devices, more
particularly to a magnetic wall decoration device.
Background Art
= There are many instances where it would be desirable to be
able to magnetically attach a rod to a wall or a ceiling in
order to display a decorative object or to hang an object.
= A number of patents disclose magnetic decoration devices with
different configurations.
= These prior art arrangements display only flat 2-dimensional
objects parallel to a wall. The so-called "refrigerator
magnet" comprises a permanent magnet made of Ferrite
(Ceramic) or Alnico (AlNiCo), and attaches directly to
ferromagnetic materials such as steel side wall of a
refrigerator. However, the magnetic attractive force of such
a permanent magnet is not strong enough to be able to attach
an object to the head of a nail in a wall.
Description of the Invention
= It is a primary object of the invention to provide a magnetic
decoration device which magnetically attaches to an exposed
or hidden nail in a wall.
= It is another object of the invention to provide a magnetic
decoration device which magnetically attaches to a hidden
wall angle in a wall.
= It is another object of the invention to provide a magnetic
decoration device which magnetically attaches to another
magnet through a window glass.
= It is another object of the invention to provide a magnetic
decoration device which magnetically attaches to a main tee
of a suspended ceiling.
= A magnetic decoration device comprises a disc-shaped rare-
earth magnet, a rod made of a light-weight material, one end
portion formed to securely attach to the disc-shaped rare-
earth magnet, and is horizontally placed in order to
1
CA 02289996 2007-05-18
magnetically attach to an exposed nail, a hidden nail, or a
hidden wall angle in a vertical wall, perpendicularly to the
wall. The magnetic decoration device may further comprise a
disc-shaped rare-earth magnet having the same surface area as
that of the magnet securely attached to the rod so that the 2
disc-shaped rare-earth magnets attach to each other through a
vertical window glass by means of a magnetic attractive
force. Another embodiment of the magnetic decoration device
has an end portion of the rod forming a hook, and is
vertically placed in order to magnetically attach to a
horizontal main tee of a suspended ceiling, perpendicularly
to the suspended ceiling.

Modes for Carrying Out the Invention
= The strong and focused magnetic field from a permanent magnet
made of Rare-Earth (NdFeB, SmCo, etc.) makes it possible to
magnetically attach a decorative object to the head of a
hidden nail or a hidden wall angle in a wall, even though the
nail or the hidden wall angle is invisible, placed behind a
few millimetres of plaster on a drywall, and covered with
paint and/or wall paper.
= Figure 1 shows 5 different embodiments of the present
invention. A magnetic decoration device marked 1-0 comprises
a rare-earth permanent magnet, a rod, and a sheet. The
magnetic decoration device magnetically attaches to an
exposed or hidden nail in a vertical wall, and displays a
2

flag or a banner. A magnetic decoration device marked 2-0
comprises 2 rare-earth permanent magnets, a rod, and a sheet.
The magnetic decoration device attaches to a vertical window
glass, and displays a greeting card or a poster. A magnetic
decoration device marked 3-0 comprises a rare-earth permanent
magnet and a rod. The magnetic decoration device magnetically
attaches to a hidden wall angle in a vertical wall, and is
able to hang an object such as a pen or a pencil. A magnetic
decoration device marked 4-0 comprises 2 rare-earth permanent
magnets and a rod. The magnetic decoration device attaches to
a vertical window glass, and is able to hang an object such
as a 3-dimensional action figure. A magnetic decoration
device marked 5-0 comprises a rare-earth permanent magnet and
a rod. The magnetic decoration device magnetically attaches
to a horizontal main tee of a suspended ceiling, and is able
to hang an object such as a 3-dimensional doll with its hook.
= Figure 2 shows a sectional view of the magnetic decoration
device 1-0 along line I-I of Figure 1. The magnetic
decoration device comprises a disc-shaped rare-earth magnet
1-1, a rod made of a light-weight material 1-2, one end
portion formed to securely attach to the disc-shaped rare-
earth magnet, and a sheet made of a light-weight material 1-3
securely attached to the rod on one end. The magnetic
decoration device is horizontally placed in order to
magnetically attach to an exposed nail, a hidden nail, or a
hidden wall angle in a vertical wall, perpendicularly to the
vertical wall. The sheet may be made of plastic, cloth or
fabric, or paper.
= Figure 3 shows a sectional view of the magnetic decoration
device 2-0 along line II-II of Figure 1. The magnetic
decoration device comprises a disc-shaped rare-earth magnet
2-1, a rod made of a light-weight material 2-2, one end
portion formed to securely attach to the disc-shaped rare-
earth magnet, a sheet made of a light-weight material 2-3
securely attached to the rod on one end, and another disc-
shaped rare-earth magnet 2-4 having the same surface area as
that of the other magnet. The magnetic decoration device is
horizontally placed so that the 2 disc-shaped rare-earth
magnets attach to each other through a vertical window glass
by means of a magnetic attractive force, perpendicularly to
the vertical window glass. The sheet may be made of plastic,
cloth or fabric, or paper.
= Figure 4 shows a sectional view of the magnetic decoration
device 3-0 along line 111-111 of Figure 1. The magnetic
decoration device comprises a disc-shaped rare-earth magnet
3-1, and a rod made of a light-weight material 3-2, one end
portion formed to securely attach to the disc-shaped rare-
earth magnet and the other end portion forming a disc, a
sphere or a hemisphere. The magnetic decoration device is
3

horizontally placed in order to magnetically attach to an
exposed nail, a hidden nail, or a hidden wall angle in a
vertical wall, and to hang an object, perpendicularly to the
vertical wall.
= Figure 5 shows a sectional view of the magnetic decoration
device 4-0 along line Iv-IV of Figure 1. The magnetic
decoration device comprises a disc-shaped rare-earth magnet
4-1, a rod made of a light-weight material 4-2, one end
portion formed to securely attach to the disc-shaped rare-
earth magnet and the other end portion forming a disc, a
sphere or a hemisphere, and another disc-shaped rare-earth
magnet 4-4 having the same surface area as that of the other
magnet. The magnetic decoration device is horizontally placed
so that the 2 disc-shaped rare-earth magnets attach to each
other through a vertical window glass by means of a magnetic
attractive force, perpendicularly to the vertical window
glass.
= Figure 6 shows a sectional view of the magnetic decoration
device 5-0 along line V-V of Figure 1. The magnetic
decoration device comprises a disc-shaped rare-earth magnet
5-1, a rod made of a light-weight material 5-2, one end
portion formed to securely attach to the disc-shaped rare-
earth magnet and the other end portion forming a hook. The
magnetic decoration device is vertically placed in order to
magnetically attach to a horizontal main tee of a suspended
ceiling, perpendicularly to the suspended ceiling.
= The rare-earth magnet must be disc-shaped, not ring-shaped.
The rod made of a light-weight material may be hollow, and
may have the diameter slightly greater than that of the disc-
shaped rare-earth magnet in order to enclose the disc-shaped
rare-earth magnet. The rod may be made of metal such as
magnesium and aluminum, plastic, or wood.
