Technical Field
[0001] The present invention relates to a magnetic knife stand and more particularly pertains
to a magnetic knife stand for storing knives.
Background Art
[0002] Different kinds of knives are kept in most kitchens for preparing various dishes.
Usually the knives are placed together in a knife rack or a knife stand for convenient
use. The existing knife racks mainly use magnets to attract the knife blades. However,
there exists a common problem that the magnetic force is likely to be too strong to
make it so difficult to remove the relatively small-sized knives from the knife racks,
while it is insufficient to attract and hold the relatively large-sized knives securely
onto the knife racks and causes accidents easily. For the sake of safety, many kitchens
use knife stands instead of knife racks. The existing knife stands comprise slits
pointing substantially downwards. Knifes are inserted into the slits and stored therein
for future use. The slits can be of different shapes and dimensions to match with
knives of different shapes and dimensions. Knife stands can therefore be used to store
the knives securely. It has the advantages of making the knives to be stored tidily
and conveniently for future use. Accidents can be avoided as the cutting edges of
the knives are not exposed.
[0003] However, the existing knife stands are mostly configured with the cutting edges of
the knives being inserted downward. When the knife is being inserted, owing to the
force of gravity the cutting edge of the knife will easily come in contact with or
even rub against the bottom of the slit. The cutting edge therefore becomes blunt
easily and has to be sharpened frequently, which is quite troublesome. The bottom
of the knife stand also wears out, thereby shortening the lifespan of the knife stand.
[0004] DE29807116U1 discloses a kind of knife rack comprising multiple modules each containing at least
one vertical back element (a) and a vertical carrier element (b); a magnet (M) is
disposed at the back of a respective back element (a). However, this kind of knife
rack only uses the magnet (M) to hold a knife vertically to prevent the knife from
falling off; the magnet (M) is not used for preventing the blade of the knife from
contacting an inner side of a sheath. This kind of structure is disadvantageous in
that, if the magnet (M) is not strong enough or if the magnet (M) fails to operate
properly, the knife will easily fall off and thus causing accidents; also, since the
blade of the knife is not fitted within a knife sheath, the blade may be exposed to
an external environment for example when the knife is too long and thus hurting the
users, or the blade may contact the spacer (D) for example when the blade is too broad
and thus liable to frequent contact and rubbing against the spacer (D) and resulting
in a blunt blade.
[0005] DE29806075U1 discloses a holding device (1) for holding various types of kitchenware. To hold
an item, for example a knife, the item is inserted into a channel (3) through a slot
(4) and it is secured in position by a magnet (10). This kind of holding device is
not preferable because the wall (8) of the channel (3) is said to closely and snugly
fit against the item being inserted. As a result, if a knife is inserted, the blade
of the knife will contact and rub against the wall (8) of the channel (3) and thus
damage the knife as well as the holding device (1).
[0006] JP2003164382A discloses a knife holder for vertical insertion of a knife. A magnet (8) is disposed
to attract and hold the sides of the knife so that the knife will not drop down and
rub against the bottom of the insertion portion (5/6/7). However, this kind of knife
holder can only prevent the knife from dropping down and thus preventing the tip of
the knife from contacting the insertion portion, but it is not able to prevent the
cutting edge of the blade from contacting an inner side of the insertion portion (5/6/7).
As a result, the knife may have a blunt blade due to frequent contact of the blade
with an inner side of the insertion portion.
[0007] US2955239A discloses a magnetic holding device which can be used in a vertical knife rack. The
knife being inserted into the vertical knife rack is held within a slot (117) by two
magnets (110, 111) mutually attracting with each other. This kind of structure can
hold the knife so that the knife will not fall off, but it cannot prevent the blade
of the knife from contacting the inner side of the slot (117). As a result, the blade
will become blunt when it contacts the inner side of the slot (117) frequently.
Disclosure of the Invention
[0008] In view of the aforesaid disadvantages now present in the prior art, the object of
the present invention is to provide a magnetic knife stand which is safe, reliable,
convenient for use and can effectively prevent the cutting edges of the knives from
becoming blunt.
[0009] To attain this, the present invention generally comprises one or more inserting slits
each receiving a blade of a knife; each of the inserting slits has a corresponding
knife sheath removably connecting to a corresponding inserting slit of the inserting
slits; the blade of the knife has a cutting edge, two side surfaces, and a back edge
directly opposite to the cutting edge; one or more magnets is/are disposed respectively
on an upper inner side of each of the inserting slits for attracting the back edge
of the blade, a hole or a hollow is disposed on the upper inner side of each of the
inserting slits, and a corresponding magnet/magnets of the magnets is/are placed inside
the hole or hollow; when the knife is inserted into the corresponding knife sheath
through the corresponding inserting slit of the inserting slits after use, the corresponding
magnet/magnets of the magnets disposed on the upper inner side of the corresponding
inserting slit attracts the knife, thereby keeping the back edge of the knife in contact
with the upper inner side of the corresponding inserting slit while being inserted
so that the cutting edge of the knife is kept at a certain distance away from the
bottom inner side of the corresponding inserting slit to avoid the cutting edge from
rubbing against the bottom inner side of the corresponding inserting slit during the
process of inserting the knife, and keeping the cutting edge of the knife in a position
away from and having no contact with the bottom of the corresponding knife sheath
after the knife is completely inserted into the corresponding knife sheath.
[0010] The one or more magnets disposed respectively on the upper inner side of each of
the inserting slits is/are disposed near to a respective opening of each of the inserting
slits.
[0011] The one or more magnets are disposed for each of the inserting slits, and the one
or more magnets can each be in the shape of a bar or a granule, depending on the shape,
dimension and weight of the knives to be attracted.
[0012] The one or more magnets can be respectively adhered to or respectively embedded into
the upper inner side of each of the inserting slits.
[0013] A first projecting member or a first groove is provided at one end of the corresponding
knife sheath which connects to a corresponding inserting slit of the inserting slits,
and a second groove corresponding to the first projecting member or a second projecting
member corresponding to the first groove is provided in acorresponding position of
the corresponding inserting slit; the corresponding knife sheath can protect the corresponding
cutting edge of the inserted knife and avoid accidents from happening.
[0014] The shape and dimension of the knife sheath correspond to the shape and dimension
of the inserted knife.
[0015] To use the present invention, while a knife is inserting into the inserting slit
of the knife stand after use, the magnet disposed on the upper inner side of the inserting
slit has the property of attracting the knife, thereby keeping the upper surface of
the knife (that is, the back of the blade) in contact with the upper inner side of
the inserting slit while being inserted. During the process of inserting the knife,
the cutting edge can be kept at a certain distance away from the bottom inner side
of the inserting slit of the knife stand, thereby avoiding the cutting edge from rubbing
against the bottom inner side. Further, after the knife is completely inserted into
the inserting slit, the magnet can keep the cutting edge of the knife in a position
of being away from and having no contact with the knife stand.
[0016] In comparison with the prior art, the present invention has the following advantages
and effects:
First, since the magnet of the magnetic knife stand can keep the cutting edge of the
knife away from the bottom inner side of the inserting slit during and after the process
of inserting the knife into the knife stand, it can effectively prevent the cutting
edge from becoming blunt, which is caused by its rubbing against the inserting slit.
The frequency of sharpening the blade can then be reduced and the lifespan of the
knife can be extended. Further, this magnetic knife stand is more effective in protecting
the knife stand from being cut or worn out by the knives.
Secondly, this magnetic knife stand provides the inserting slits for placing the knives
and magnets are disposed to attract the back of the blade. This is effective to store
the knives securely in the knife stand. It is convenient for use. It is safer and
more reliable when used with knife sheaths.

[0018] The present invention is further described in detail with the following embodiment
and the accompanying drawings. FIGS. 1 and 2 illustrate an embodiment of this magnetic
knife stand. It has an appearance of a human figure. Its appearance can be changed
freely into any traditional knife stand or other appearance. As illustrated in FIGS.
1 and 2, this magnetic knife stand comprises a base 1 and a supporting stand 2. The
supporting stand 2 is fixed firmly onto the base 1. As illustrated in FIG. 2, inserting
slits 21 are disposed in various positions of the supporting stand 2. Magnets 5 are
embedded into holes or hollows disposed on the upper inner side of the inserting slits
21 near to their openings. As illustrated in FIGS. 3 and 5, the shape of the magnets
5 is in bar form. The thickness of the magnets 5 shall not affect the insertion of
knives 4. The inserting slits 21 have corresponding knife sheaths 3. One end of the
knife sheaths 3 which connect to the inserting slits 21 comprises projecting members
31. The knife sheaths 3 are inserted into the supporting stand 2 by means of the projecting
members 31 and connect to the inserting slits 21 correspondingly. The knife sheaths
3 can be removed conveniently when required (for example, when the knife stand has
to be packed). While a knife 4 is inserting into the knife sheath 3 after use, the
magnet 5 disposed on the upper inner side of the inserting slit 21 has the property
of attracting the knife 4, thereby keeping the upper surface of the knife 4 (that
is, the back of the blade) in contact with the upper inner side of the inserting slit
21 while being inserted. During the process of inserting, the cutting edge of the
knife 4 can be kept at a certain distance away from the bottom inner side of the inserting
slit 21, thereby avoiding the cutting edge from rubbing against the bottom inner side.
Further, after the knife 4 is completely inserted, the magnet 5 can keep the cutting
edge of the knife 4 in a position of being away from and having no contact with the
bottom of the knife sheath 3. As illustrated in FIGS. 1 and 3, after the blade 41
of the knife 4 is inserted into the knife sheath 3, its handle 42 is located outside
the knife sheath 3 and the supporting stand 2.
