Description

  The present invention relates to a knife storage device, and particularly relates to a reduction in the burden on the blade portion of a knife.

  Generally, a kitchen knife used at home is stored in a storage case provided inside a door or the like. The storage method is to insert the blade portion of a knife into a hole formed on the upper side of the storage case (see Patent Documents 1 and 2).

  However, when storing, the cutting edge of the knife has to be inserted into the hole of the storage case, which requires a relatively cumbersome operation.

  Further, since the blade portion of the kitchen knife is stored by being inserted into and removed from the hole of the storage case, the blade of the kitchen knife hits the side surface of the hole of the storage case, which causes blade spillage.

  Accordingly, the present applicant has devised a cookware holder (design registration No. 1064393) to solve the above problem. According to the present invention, a permanent magnet enables a kitchen utensil such as a kitchen knife to be held, and the surface on the back side of the holding surface is fixed to a surface such as a wall that is easy for a user to use. Made it possible.

In this case, since the side surface of the knife portion of the kitchen knife is fixed with a magnet, the cumbersome work of inserting the knife edge of the knife into the hole of the storage case can be avoided.

  However, in the said invention, since the magnetic field of the magnet was too strong, when separating a kitchen knife and the said cooker holder, big force was needed and it was also a cause of the knife blade bending.

  Further, according to the shape of the invention, the blade of the knife hits a bag or the surface of a case or the like, which is a non-magnetic material that wraps the magnet, causing the knife blade to be missing. In addition, since the case and the like are made of a non-magnetic metal, the metal sound generated when the knife is held by suction is also noisy.

  The present invention has solved the above problems.

  In order to solve the above-mentioned problem, the invention according to claim 1 includes a permanent magnet, a magnet protective cover disposed on one end face of the permanent magnet and having a hole, and the permanent magnet and the magnet protective cover. In a magnet type knife holder comprising a case portion for storing a knife holding sheet portion having a protruding portion that is disposed between and protruding from the hole portion, the upper surface of the protruding portion is a surface of the magnet protection member, And it protrudes from the said case part, It is characterized by the above-mentioned.

  According to the configuration of the present invention, the protrusion of the knife holding sheet portion disposed between the permanent magnet and the magnet protective cover penetrates the hole of the knife holding sheet portion and is more than the knife holding sheet portion. Since it protrudes, the side surface of the kitchen knife, which is a non-holding body, is held by the protrusion of the knife holding sheet portion and does not come into contact with the magnet protection member.

  The invention according to claim 2 is the magnet type knife holder according to claim 1, wherein the material of the knife holding sheet portion is a synthetic resin. According to the structure of the invention which concerns on Claim 2, the side surface of the blade part of the held knife becomes difficult to be damaged.

  The invention according to claim 3 is the magnet knife holder according to claim 1, wherein the material of the knife holding sheet portion is nylon. According to the structure of the invention which concerns on Claim 3, it becomes difficult to damage the side surface of the blade part of the knife held. And the trace of the upper surface of the said projection part does not remain in the side surface of the blade part of the knife held in contact with the upper surface of the said projection part, and it is hygienic.

  The invention according to claim 4 is the magnet knife holder according to any one of claims 1 to 3, wherein the magnet protective cover is made of a non-magnetic material. According to the configuration of the invention according to claim 4, even if the blade portion of the knife is opposed to the magnet protection cover, the blade portion of the knife is not attracted to the magnet auxiliary protection cover itself.

  According to a fifth aspect of the present invention, in the magnet type knife holder according to the first to fourth aspects, the material of the case portion is a non-magnetic material. According to the configuration of the invention according to claim 5, the knife to be held is not attracted to the case portion.

  The magnet type knife holder according to the present invention has the following excellent effects.

  The side surface of the blade portion of the knife is held in contact with the upper surface of the protrusion formed on the knife holding sheet portion. Therefore, even if the blade portion of the kitchen knife is attracted by the magnetic force of the magnet, it does not collide with the case portion, and an unpleasant metal sound does not occur.

  In addition, by adjusting the degree of protrusion of the protrusion of the knife holding sheet, it is possible to weaken the knife's attractive force without selecting a magnet with a weak magnetic field, and a large force is required for separation. In addition, the blade portion of the knife is not curved.

  And since the blade part of a kitchen knife does not contact with a magnet protection member, the problem that the said blade part is missing does not arise.
