Into which the knife 2 is inserted. The opened surface is the upper wall 1a, the surface fixed to the vertical surface of the plate body such as the cabinet 10 is the rear wall 5, and the opposite side surface is the front wall 1F.
The upper wall 1a has an inclination that descends toward one side. In the case of the present embodiment, the upper wall 1a has an inclination that descends from the rear wall 5 side to the front wall 1F side. Hereinafter, the inclination direction of the upper wall 1a is referred to as “front-rear direction”, and the direction substantially orthogonal to the front-rear direction is referred to as “left-right direction”.

  The knife insert 1 is mainly composed of an upper wall 1a into which the knife 2 is inserted, and a front wall 1F, a left wall 1L, and a right extending continuously downward from the front end, the left end, and the right end of the upper wall 1a. A side wall composed of a wall 1R, a lower wall 1b continuous to the lower ends of the side walls 1F, 1B, 1L, and 1R, and a rear end of the upper wall 1a, the left wall 1L, the right wall 1R, and the lower wall 1b And a rear wall 5. And it attaches to vertical surfaces (elevation surface), such as the back surface of the opening-and-closing door 10 of the cabinet etc. which are arrange | positioned in a kitchen, and the side wall inner surface of a cabinet.

  The knife holder 1 in this embodiment is formed from a resin such as plastic or a material such as ceramics, and the upper wall 1a, front wall 1F, left wall 1L, right wall 1R, and lower wall 1b are integrally formed. It has become one member. The rear wall 5 is fixed to the back surface of the door 10 with screws or the like, so that the knife holder 1 is fixed to the back surface of the door 10.

As shown in FIG. 6, the upper wall 1a, front wall 1F, left wall 1L, right wall 1R, and lower wall 1b of the knife holder 1 are integrally formed of a resin such as plastic, etc. Knife insertion holes 1c, 1c,... Are drilled in the upper wall 1a. Further, attachment pieces 6, 6... Are formed at rear end portions of the upper wall 1a, the left wall 1L, the right wall 1R, and the lower wall 1b.
Then, the knife insert 1 can be assembled by fixing the rear wall 1B, which is a plate-like member made of resin or the like, to the mounting pieces 6, 6...

  As shown in FIG. 1, the upper wall 1a of the knife insert 1 is inclined so that the front portion is lower than the rear portion, and the knife insertion hole for inserting the knife 2 from above is inserted into the upper wall 1a. A plurality of 1c, 1c... Are formed. In this embodiment, six (plural) knife insertion holes 1c, 1c,... Are formed in the upper wall 1a, but the number of knife insertion holes 1c, 1c,. . That is, the present invention can also be applied to the knife holder 1 in which one knife insertion hole 1c is formed.

The knife insertion hole 1c is an opening of the knife insert 1 into which the blade 3a of the knife 2 is inserted. In the knife insertion hole 1c, a groove portion 1e into which the blade portion 3a can be inserted and a blade base insertion portion 1d into which the blade base portion can be inserted are formed.
The groove 1e has a long direction and a short direction according to the shape of the blade 3a of the knife. Further, as shown in FIG. 2, the groove portion 1e is formed such that the longitudinal direction thereof is inclined from the front-rear direction, and the upper wall 1a has an upper end and a lower end due to the inclination of the upper wall 1a. In the present embodiment, the longitudinal direction of the groove portion 1e is formed so as to be from the right rear to the left front direction, but the longitudinal direction of the groove portion 1e is formed so as to be from the left rear to the right front direction. It may be and is not limited.

  As shown in FIGS. 2 to 4, the groove portion 1e of the knife insertion hole 1c has a front portion formed wider than the rear portion, and the blade base portion 3b and the handle 4 of the knife 2 are inserted into the lower end side of the groove portion 1e. It has a configuration. And the lower end side of the groove part 1e of this knife insertion hole 1c is expanded further forward so that the blade base part 3b can be inserted, in other words, forward to the inner periphery of the left front portion of the knife insertion hole 1c. A notch is provided to form a blade base insertion portion 1d. That is, the blade base 3b of the knife 2 inserted into the groove 1e of the knife insertion hole 1c can be moved from the lower end of the groove 1e along the blade base insertion 1d in the inclination direction of the upper wall 1a. Yes.

As described above, in the case of the knife insertion hole 1c of the type in which the longitudinal direction of the groove portion 1e is formed from the left rear to the right front direction, the right front portion of the knife insertion hole 1c extends forward. As a result, the blade base insertion portion 1d is formed.
That is, as a knife insertion hole 1c into which the blade portion 3a of the knife 2 is inserted, a groove-shaped groove portion 1e adapted to the shape of the blade portion 3a of the knife 2 and a lower side where the handle 4 of the knife 2 of the groove portion 1e is located. The blade base insertion portion 1d provided at the end of the blade is continuously formed. The blade base insertion portion 1d is formed such that the blade base 3b of the knife 2 located at the lower end of the groove 1e can move downward substantially parallel to the inclination direction of the upper wall 1a.

  Specifically, as shown in FIGS. 3 and 4, the knife 2 is inserted into the knife insertion hole 1c by the user, and the blade base 3b is placed at the rear end of the blade base insertion part 1d (the front of the knife insertion hole 1c). When the handle 4 reaches and contacts the upper surface of the upper wall 1a, the blade 3a does not interfere with the upper wall 1a, so that the blade base 3b can slide along the hole shape of the blade base insertion portion 1d. That is, the knife 2 is movable in the front-rear direction along the shape of the blade base insertion portion 1d. Since the upper wall 1a of the knife holder 1 of the present invention is formed so that the front is lowered, the handle 4 of the knife 2 automatically moves downward along the upper surface of the upper wall 1a, that is, forward. .

  As shown in FIG. 4 (d), when the handle 4 and the blade base 3b of the knife 2 are moved forward, the blade 3a of the knife 2 does not overlap with the knife insertion hole 1c in plan view, and the knife is inserted. Since the front portion (upper wall 1a) of the hole 1c and the blade portion 3a of the knife 2 overlap with each other in a plan view, even if a user or the like tries to pull out the knife 2, it cannot be pulled out. . That is, since the upper end of the blade portion 3a of the knife 2 and the lower surface of the upper wall 1a come into contact with each other and the upward movement of the knife 2 is restricted, the knife 2 cannot be pulled out.

  As described above, in the knife holder 1 of the present invention, after the blade base 3b (knife 2) is moved forward, the user or the like moves the knife 2 backward, and the handle 4 and the blade base 3b are inserted into the knife in plan view. The knife 2 cannot be pulled out from the knife holder 1 unless it is adjusted so as to overlap with the groove 1e of the hole 1c in plan view.

In addition, as shown below, the knife insert 1 having the above-described configuration can further complicate the lock by increasing the operation for removing the blade base portion 3b of the knife 2 from the blade base insertion portion 1d.
For example, as shown to Fig.5 (a), it can be set as the obstruction at the time of the knife 2 moving back by providing the convex part 5g which protruded to the inner peripheral side of the hole in the blade base insertion part 1d. In detail, the convex part 5g is formed in the inner peripheral surface of the front-back substantially center part or lower end of the blade base insertion part 1d toward the inner side of the blade base insertion part 1d. Thus, after the blade base 3b (knife 2) has moved forward, the convex portion 5g becomes an obstacle to the movement of the blade base 3b to the rear, so that the knife 2 cannot be easily extracted from the knife insert 1. . In other words, as long as the width in the left-right direction at the substantially central portion or the lower end of the blade base insertion portion 1d is narrow, the left and right sides of the blade base insertion portion 1d may be as shown in FIG. The structure which forms convex part 5g * 5g in both internal peripheral surfaces may be sufficient.
With the above configuration, a child or the like cannot easily take out the knife 2 from the knife holder 1, and an accident can be prevented.

Next, with reference to FIGS. 3 and 4, the method of using the knife holder 1 of the present invention will be described in detail.
When the knife 2 is inserted into the knife holder 1, the blade 3a and the blade base 3b of the knife 2 are positioned above the knife insertion hole 1c, the blade 3a is located above the knife insertion hole 1c, the blade base 3b and the handle. The posture is adjusted so that 4 is positioned above the left front portion of the knife insertion hole 1c (see FIGS. 3 and 4A). And the knife 2 is inserted in the knife insertion hole 1c, maintaining the said attitude | position (refer (b) of FIG.3 and FIG.4). When the blade base 3b reaches the blade base insertion portion 1d, or when the lower surface of the handle 4 comes into contact with the upper surface of the knife holder 1 (see FIG. 3 and FIG. 4C), the handle 4 and the blade base 3b are moved forward. Slide (see (d) of FIG. 3 and FIG. 4).
When the knife 2 is inserted into the knife insertion hole 1c, the knife 2 moves downward (forward) by its own weight along the shapes of the knife insertion hole 1c and the blade base insertion part 1d.

As described above, when removing the knife 2 from the knife holder 1, the knife 2a and the blade base 3b overlap the groove 1e of the knife insertion hole 1c in plan view by moving the knife 2 backward and turning it. It is necessary to let
Specifically, the user or the like first moves the knife 2 backward to bring the blade base 3b into contact with the front rear surface of the knife insertion hole 1c. Then, the knife 2 is rotated in the contacted state, and the blade part 3a is adjusted so as to overlap the groove part 1e of the knife insertion hole 1c in plan view. The knife 2 is pulled upward with the posture adjusted as such.

  That is, the feature of the present invention is that not only the process of turning the knife 2 but also the process of sliding the knife 2 backward (upward of the slope formed on the upper wall 1a) when pulling out the knife 2 is necessary. In the point. Thereby, it becomes impossible for a child etc. to take out the kitchen knife 2 from the kitchen knife insert 1 easily, and an accident can be prevented. Further, since the knife 2 is slid rearward to release the lock, it is advantageous in the present invention that a complicated lock mechanism is not required or that the trouble of releasing the lock mechanism is unnecessary. is there.

  Thus, it is a knife insert 1 in which one or a plurality of knife insertion holes 1c, 1c... Are formed in the upper wall 1a of the box body, and the upper wall 1a has an inclination that goes down toward one side. The knife portion 3a of the knife 2 can be inserted into the knife insertion holes 1c, 1c,..., The groove portion 1e whose longitudinal direction intersects the inclined direction of the upper wall 1a, and the blade base portion of the knife 2 3b can be inserted, the blade base 3b can be moved substantially parallel to the inclination direction of the upper wall 1a, and a blade base insertion portion 1d continuous with the lower end of the groove 1e is provided. Therefore, it is possible to prevent an accident by a child or the like without providing a complicated locking mechanism. As a result, the knife holder 1 provided with the lock mechanism can be made compact, and the manufacturing cost can be reduced.

  Moreover, since the convex part 1g was formed in the inner peripheral direction of the hole of this blade base insertion part 1d in the inclination direction approximate center part or upper end part of the upper wall 1a of the said blade base insertion part 1d, Since the convex part 1g becomes an obstacle when moving to, the reliability of the lock mechanism can be improved.

As shown in FIG.1 and FIG.7, the knife insert 1 of this invention is comprised so that the width | variety of the front-back direction of a lower part may become smaller than the width | variety of the front-back direction of an upper part. Specifically, a level difference 1h is formed at a substantially middle portion of the front wall 1F in the vertical direction, and the lower portion of the front wall 1F is located at a rear position from the upper portion. According to such a shape, the thickness in the front-rear direction of the lower part of the knife holder 1 can be further reduced, and the space inside the kitchen sink can be used effectively. Further, according to such a shape, the blade portion 3a of the knife 2 inserted in the knife knife 1 does not shake, and when the knife is pulled out, the knife comes into contact with the inside of the knife knife 1, The knife 2 is easy to operate.
However, the present invention is not limited to the configuration in which the entire portion of the front wall 1F below the step 1h is located rearward as shown in FIGS. 1 and 7, but when the knife 2 is inserted into the knife insertion hole 1c. The blade portion 3a of the knife 2 may be configured to abut on the back surface of the front wall 1F.
In other words, any structure is acceptable as long as the moisture adhering to the blade 3a of the knife 2 flows down along the back surface of the front wall 1F.

  Thus, since the lower part of the side wall 1F corresponding to the lower side in the inclination direction of the upper wall 1a of the knife holder 1 is set back, the knife 2 inserted into the knife insertion hole 1c is prevented from wobbling. In addition, since the water droplets attached to the knife 2 flow down along the back surface of the front wall 1F, rusting of the knife 2 can be prevented.

  In other words, the front / rear width of the lower part of the kitchen knife insert 1 is configured to be shorter than the front / rear width of the upper part, and the lower part of the kitchen knife 2 inserted into the knife insertion hole 1c is formed on the back surface of the front wall 1F of the kitchen knife insert 1 Since it abuts, the knife 2 inserted into the knife insertion hole 1c can be prevented from wobbling, and water droplets attached to the knife 2 flow down along the back surface of the front wall 1F, so that the knife 2 can be prevented from rusting.
