Description

[Detailed description of the invention] [Industrial field of application] This invention is used by attaching it to a kitchen knife when cutting cooking ingredients such as vegetables, bread, cheese, etc. into the same width (thickness) and size. This relates to a cutting width setting device.

[Conventional technology]

Conventionally, in order to cut cooking ingredients to the same width (thickness) and size, a sensing rod was installed that moved parallel to the knife blade to determine the cutting width, and the distance between the sensing rod and the blade was adjusted. A kitchen knife has been proposed that can be adjusted to cut cooking ingredients at the set width.

[Problem that the invention attempts to solve]

With conventional models, the detection rod is not designed to rotate vertically, so when you lower the knife to cut the cooking ingredients, the detection rod hits the cutting board before the blade, causing the blade to hit the cutting board as it is. In this case, the knife cannot be cut down until it hits the cutting board,
It has the drawback that cooking ingredients cannot be completely separated, so cooking cannot be done smoothly.Also, since the cutting width setting device with a detection rod is integrally formed on the knife, it cannot be attached to a typical household knife. The disadvantage is that it cannot be used.

In view of the above points, the present invention improves usability by allowing the detection rod to freely rotate up and down, and when the knife is lifted, the detection rod stops at a position slightly protruding downward from the blade. The purpose of the present invention is to provide a cutting width setting device that can be easily attached to and detached from a kitchen knife.

[Means for solving problems]

In order to achieve the above object, the present invention includes a support 2 equipped with a detection rod 1 that determines the cutting width a while keeping parallel to the knife 3, and a support 2 that is slidably supported on a setting board 5 that sets the cutting width. In the cutting width setting device, which can be fixed by an appropriate fixing means at the set position, the detection rod 1 is pivoted to the support 2 so that it can rotate freely up and down, and the tip of the detection rod 1 is lower than the cutting edge of the knife 3. Place the detection rod 1 so that it stops at a position that protrudes slightly downward.
The rotation is restricted at the base end of the
Further, a mounting tool 6 is provided on one side of the setting board 5 to detachably attach the setting board 5 to the knife 3.

[Function] With the above configuration, when the fixture 6 provided on one side of the setting board 5 is fitted and fixed to the handle 14 of the knife 3,
The cutting width setting device is attached to the knife 3, the detection rod 1 is positioned parallel to the blade 4 of the knife 3, and the support 2 is slid against the setting board 5 to connect the blade 4 of the knife 3 and the detection rod 1.
The cutting width a is determined by setting the distance between the cutting width and the cutting width a to a desired width, and the support tool 2 is fixed to the setting board 5 by an appropriate fixing means. After that, cooking ingredients A placed on a cutting board etc.
When the knife 3 is lifted up to cut bread, cheese, etc., the rotation of the detection rod 1 is restricted at its base end, and it stops at a position slightly protruding below the blade 4 of the knife 3, and the detection rod 1 stops on one side of the cooking material A, etc. When the knife 3 is cut down by touching the side surface of the tip of the detection rod 1 to the end surface, the tip of the detection rod 1 first hits the cutting board and the detection rod 1 rotates upward until the blade 4 of the knife 3 hits the cutting board. Then cooking material A is completely cut. The cooking material is then cut with a cutting width determined by the distance between the blade 4 of the knife 3 and the detection rod 1. By repeating this operation, the cooking material A is sequentially cut into desired widths.

When the cutting width setting device is not used, the knife 3 and the cutting width setting device can be separated by removing the attachment 6 from the handle 14 of the knife 3 and can be used as a normal kitchen knife 3.

〔Example〕

1 to 3 show an embodiment of the cutting width setting device according to the present invention, in which 1 is a detection rod that determines the cutting width a, and its base end is pivoted to the tip of the support 2. 15, so that it can freely rotate up and down using the pivot 15 as a fulcrum. The detection rod 1 abuts against one side end surface of the cooking material A to be cut, thereby determining the distance between the detection rod 1 and the blade 4 of the kitchen knife 3. 5 is a setting board that slidably supports the base end of the support 2;
The upper and lower substrates 5 have a space that allows the base end portions to be loosely inserted.
A and 5b are formed, and a slide groove 7 is bored in the upper substrate 5a, and a scale 8 indicating the cutting width is provided on the surface thereof. An engagement protrusion 9 protruding from the base end of the support 2 is slidably and loosely fitted into the slide groove 7, and an adjustment fixing screw 10 is fitted into the slide groove at the center of the engagement protrusion 9. 7, and by moving the support 2 along the slide groove 7 with the adjusting and fixing screw 10, the detection rod 1 can be moved in parallel to the blade 4 of the knife 3. The lower board 5b is provided with a groove 11 in the center into which the tip of the adjusting and fixing screw 10 fits and moves, and when the detecting rod 1 is held at the set position, turning the adjusting and fixing screw 10 causes the support 2 to move. The base end portion of the adjustment screw 10 is raised, and the upper surface of the base end portion is pressed against the upper substrate 5a side, and the tip of the adjustment fixing screw 10 is strongly pressed against the grooved line 11 and fixed.

A fixture 6 for the knife 3 is integrally fixed to one side of the setting board 5, which has a U-shaped cross section and is provided with a screw hole 12 into which a fixing screw 13 is screwed into one side plate. The setting board 5 is located at a right angle. When the fixture 6 is fitted onto the handle 14 of the knife 3 and fixed to the knife 3 by tightening the fixing screw 13, the detection rod 1 and the blade 4 of the knife 3 are always parallel to each other. The fixing screw 3 may be a thumbscrew so that it can be easily attached and detached. In addition, since the detecting rod 1 of the support 2 cannot approach the side of the blade 4 of the knife 3 due to the thickness of the handle 14 of the knife 3, the support 2 is bent to reduce the distance between the blade 4 and the detecting rod 1. I'm trying to make it possible. In addition, the tip of the support 2 is made into a U-shape, and the base end of the detection rod 1 is inserted between the tips and the pivot 15
Detection rod 1 is pivoted so that it can move up and down freely, and the tip of detection rod 1 is slightly wider than the cutting edge of knife 3 so that when knife 3 is lifted, detection rod 1 does not rotate too much downward due to its own weight. The upper surface 16 of the proximal end of the detection rod 1 is placed in contact with the lower tip of the support 2 so that the detection rod 1 stops at the downward position.

[Effect of idea]

As mentioned above, the cutting width setting device according to the present invention has a detection rod that can freely rotate up and down, so the knife blade can be cut down until it touches the cutting board, and the cutting width setting device according to the present invention can be cut down until it touches the cutting board, and the cutting width setting device can cut the cooking ingredients one by one while completely separating them. You can cut it and go. Furthermore, even when the knife is lifted, the detection rod stops at a position slightly protruding from the cutting edge of the knife, making it easy to set the cutting width of cooking materials, etc., and is convenient to use.

In addition, the attachment on one side of the cutting width setting device allows it to be attached to knives used in general households as needed, so there is no need to purchase a knife with a dedicated cutting width setting function. It is extremely convenient.
