Description
REFERENCE TO RELATED APPLICATIONS
[0001] This application is a Continuation-In-Part of International
Patent Application No. PCT/IL11/00652, filed on Aug. 10, 2011, now
pending, and claims priority from U.S. Provisional Patent
Application No. 61/344,512, filed on Aug. 12, 2010, now expired,
both of which applications are hereby incorporated by reference in
their entireties.
FIELD OF THE INVENTION
[0002] The present invention relates to a suspending device and,
more specifically, to a magnetic suspending device provided with a
temporarily attachable flexible member.
BACKGROUND OF THE INVENTION
[0003] Flexible permanent magnetic materials are often supplied in
the form of sheets or rolls and have been commercially available
for many years. These materials are typically prepared by mixing a
powdered ferrite material with a suitable polymeric or plastic
binder into a uniform mixture. The polymeric materials are often
elastomers, and the process is therefore typically accomplished
through the use of sheet extrusion or calendering. The mixture is
converted into strip or sheet form, providing a permanent stable
product that is usually somewhat flexible, and that can readily be
handled and made into elements of any desired shape by cutting
and/or stamping.
[0004] The magnetic material is permanently magnetized so that the
resulting elements can act individually as permanent magnets, the
magnetic field being of sufficient strength that they will adhere
to a magnetically attracted surface, such as the surface of an iron
or steel sheet, even through a sheet of paper or thin cardboard.
Many magnetic materials and the resultant sheet materials are
typically inherently dark in color and it is therefore usual to
attach these magnets to a printable substrate such as paper or
plastic by gluing. It is therefore to the paper or plastic that the
decorative pattern and/or other information may be printed. A
popular application of such materials is thin, flat magnets having
on their outer surface a decorative pattern and/or promotional
information, including advertisements in direct mailings, newspaper
inserts, and so forth, box toppers, coupons, business cards,
calendars, greeting cards, postcards, and so forth.
[0005] It should be emphasized that a minimal force F.sub.m of
attractive interaction between the magnetizable plate and the
magnetic member is defined by the following expression:
F m > F g k fr , ##EQU00001##
where F.sub.g is a force applied to the magnetic member by the
hanged object due to gravity; k.sub.fr is a coefficient of friction
between the magnetizable plate and the magnetic member.
[0006] JP2005218487 ('487) discloses a magnetic hook provided with
higher handleability which enables the simple removal thereof
attracted on the wall surface. The magnetic hook has a magnet
mounting body with a magnet mounted thereon, a hook mounting body
which is mounted on the magnet mounting body so as to be turned on
a pivot while having a hook mounted thereon and a wall pad which is
provided on the hook mounting body positioned above the pivot so as
to approach the wall surface when attracted thereon. When the hook
is raised ahead, the wall pad is pressed onto the wall surface by a
prescribed moment force under the principle of leverage on the
pivot, eventually causing a force to separate the magnet mounting
body from the wall surface. This enables the simple removal of the
magnetic hook magnetically attracted onto the wall surface simply
from the wall surface.
[0007] '487 prescribes to apply a force to the magnet and separate
it from the wall surface. If the magnetic hook is designed for
hanging the heavy-weight object, the aforesaid force required for
magnet separation can reach largeness so that magnet separation
becomes difficult and troublesome. Thus, it is a long-felt and
unmet need to provide a magnetic hook which is adapted for hanging
heavy-weight objects and easy separation from the wall surface in
the meantime.

DETAILED DESCRIPTION OF THE INVENTION
[0104] The following description is provided, alongside all
chapters of the present invention, so as to enable any person
skilled in the art to make use of said invention and sets forth the
best modes contemplated by the inventor of carrying out this
invention. Various modifications, however, are adapted to remain
apparent to those skilled in the art, since the generic principles
of the present invention have been defined specifically to provide
a device 100 for temporarily suspending an object of interest by
means of magnetically fixating the aforesaid object on--or to--a
surface of interest 150.
[0105] It should be emphasized that a minimal force F.sub.m of
attractive interaction between the magnetizable surface 120 and the
magnetic hanger 110 is defined by the following expression:
F m > F g k fr , ##EQU00002##
where:
[0106] F.sub.g is a force applied to the magnetic hanger 110 by the
hanged object due to gravity; k.sub.fr is a coefficient of friction
between the magnetizable surface 120 and the magnetic hanger
110.
[0107] A force of magnetic attraction between two substantially
flat bodies where one of them is a flat permanent magnet and
another is a plate made of a magnetizable material depends on the
following parameters: [0108] (a) magnetic moment per unit volume of
the magnet; [0109] (b) magnet volume; [0110] (c) magnetization
value of the magnetizable material; and [0111] (d) contact area
between the magnet and magnetizable member.
[0112] The force F.sub.m is proportional to each abovementioned
parameters.
[0113] A conception of a magnet disengageably fixatable on a
magnetizable object of interest is a trade-off between a load which
can be carried by the magnet and ease of disengagement of the
magnet from the magnetizable object.
[0114] In accordance with the current invention, magnet
disengagement can be significantly facilitated due to gradual
separation from each other. The advantage of the proposed technical
solution is in opportunity of increase in the load carriable by the
fixated magnet.
[0115] In accordance with the current invention, a flexible magnet
hanger 110 is gradually separatable from the magnetizable surface
120. An edge 115 of the flexible hanger 110 is striped from the
magnetizable surface 120 and further other portions of the magnet
hanger 110 are separated from the magnetizable surface 120.
[0116] Reference is now made to FIG. 1a, presenting a magnetizable
surface 120 mechanically fixed to a surface of interest 150, e.g. a
room wall. Any surface including a curved surface situated at any
angle relative to gravity direction is in the scope of the current
invention.
[0117] Reference is now made to FIG. 1b, showing a flexible
magnetic hanger 110 provided with a hanging element 140 adapted for
carrying a load (not shown). The magnetic hanger 110 constitutes a
flexible permanent magnet prepared by mixing a powdered ferrite,
neodymium or NeFeB material with a suitable polymeric or plastic
binder into a uniform mixture. The mixture is converted into sheet
form by means of extrusion or calendering.
[0118] Reference is now made to FIG. 2a, presenting the flexible
magnetic hanger 110 placed on the magnetizable surface 120
mechanically connected to the surface of interest 150, which
constitute together a device 100. When placed nearby the
magnetizable surface 120, the flexible magnetic hanger 110 is
fixated on the magnetizable surface 120 due to the force of
magnetic attraction. As stated above, the aforesaid force is
proportional to a volume of the magnetic hanger 110 and the contact
area. Thus, the carried load can be increased by means of sheet
thickening and extension of the contact area.
[0119] Reference is now made to FIG. 2b, showing the flexible
magnetic hanger 110 at the step of disengaging from the
magnetizable surface 120. The edge 115 of the hanger 110 is striped
from the surface 120. Further, the hanger 110 is gradually
separated from the surface 120. It should be emphasized that
novelty of the current invention is in flexibility of the magnetic
hanger 110 providing easy gradual disengagement of hanger 110 from
the surface 120.
[0120] Reference is now made to FIG. 3, presenting an embodiment of
the device 100 for temporarily suspending an object of interest.
The flexible magnetic hanger 110 further comprises pull flaps 160
which assist in tearing the magnetic hanger 110 off. Non-magnetic
flaps 160 are in the scope of the current invention. A plate 185 is
provided with mortises 180 adapted for fixating a substitutable,
exchangeable or disposable hanging element 140.
[0121] Reference is now made to FIGS. 4a and 4b, presenting the
magnetizable surface 120 attached to the surface of interest 150.
The magnetizable surface 120 is underlain by a mesh 170 which is
filled by a filler. FIG. 4b mesh 170 presents a filled mesh 170
which is flush with the surface of interest 150.
[0122] Reference is now made to FIG. 5, presenting an embodiment of
the device 100 for temporarily suspending an object of interest.
The flexible magnetic hanger 110 is provided with pull flaps 160
which assist in tearing the magnetic hanger 110 off. Further the
flexible magnetic hanger 110 is provided with rib 130 for
additional non-flexibility in a direction along the aforesaid rib
130. The ribs 130 in FIG. 5 are formed by longitudinal folds 190 of
the thin plane. The folds 190 are raised above the surface 120 to
facilitate the peeling of the hanger 110 from the surface 120.
[0123] Reference is now made to FIG. 6 presenting the magnetic
hanger 110 configured with a thin plane X-Y The plane's main axis X
comprising a first edge X.sub.1 and an opposite second edge
X.sub.2. The hanger 110 characterized by having one or more
non-flexible stiffening ribs 130 provided substantially in parallel
to the plane's main axis Y The ribs 130 having a width
W<<(X.sub.2-X.sub.1), such that the hanger 110 is provided
with flexibility along the main axis X, whilst being non-flexible
in other directions, ensuring that peeling of the hanger 110 from
the surface 120 is restricted to a direction parallel to the main
axis X, starting from at least one edge X.sub.1 and/or X.sub.2.
[0124] Reference is now made to FIGS. 7 and 8 describing another
embodiment for the magnetic hanger 110 configured with a thin plane
X-Y The plane's main axis X comprising a first edge X.sub.1 and an
opposite second edge X.sub.2. The plane's main axis Y comprising a
first edge Y.sub.1 and an opposite second edge Y.sub.2.
[0125] The hanger 110 characterized by comprising two or more
non-flexible stiffening ribs 130 provided along--and perpendicular
to--a predetermined path 220. The ribs (130) having a width W.sub.r
substantially smaller than the plane's dimensions
W.sub.r<<(X.sub.2-X.sub.1), W.sub.r<<(Y.sub.2-Y.sub.1).
Such that the hanger 110 is provided with flexibility along the
path 220, whilst being non-flexible in directions other than along
the path 220, ensuring that peeling of the hanger 110 from the
surface 120 is restricted to a direction parallel to the path 220,
starting from at least one edge of the path 220.
[0126] The ribs in FIG. 7 are described in a Polar coordinate
system (r, .theta.), where the ribs 130 are set along--and
perpendicular to--a path 200 parallel to the .theta. axis.
[0127] The ribs in FIG. 8 are described in a Cartesian coordinate
system (X, Y), where the ribs 130 are set along--and perpendicular
to--a path 200 having a snake-like configuration.
