  The present invention is intended to provide a new cutting board that allows a disabled person or an elderly person who has difficulty in using his / her hand to easily cut a food straight on a cutting board.

  In view of such a problem, the present invention is capable of inserting a cutting edge receiving portion capable of pivotally locking a cutting edge of a knife and a knife blade of the knife, and the blade blade with respect to the plate surface of the cutting board. A cutting board with a guide hole that can be guided so as to slide vertically is proposed.

The method of using the cutting board of the present invention will be described. The food material is placed on the surface of the cutting board, preferably below the guide hole, and the knife blade is inserted into the guide hole from above the food material to cut the cutting edge of the knife. The knife can be rotated perpendicularly to the plate surface of the cutting board by engaging the receiving portion and turning the blade of the knife downward along the guide hole with the cutting edge as a fulcrum. At this time, if the cutting edge of the knife is pierced and can be locked so as to be rotatable, the principle of the lever can be used, and the food can be cut with a smaller force.
As described above, when the cutting board of the present invention is used, foodstuffs can be cut straight on the cutting board even by a disabled person or an elderly person who is difficult to use hands freely.

It is the perspective view which showed the cutting board which concerns on an example of this invention. It is the perspective view which showed an example of the use condition of the cutting board which concerns on an example of this invention. It is sectional drawing which showed an example of the use condition of the cutting board which concerns on an example of this invention.

  In this section, an example of an embodiment for carrying out the present invention will be described, but the present invention is not limited to the embodiment described below.

  As shown in FIG. 1, a cutting board 1 (referred to as a “main cutting board”) 1 according to the present embodiment stands on a plate surface 31 of a cutting board 30 and can lock a cutting edge 51 of a knife 50 so as to be rotatable. A strut portion 2 provided with a cutting edge receiving portion 3 and an arch shape extending from the strut portion 2 to the plate surface 31 of the cutting board 30, the blade 52 of the knife 50 can be inserted, and the plate surface of the cutting board 30 And a frame portion 4 provided with a guide hole 5 that can be guided so as to slide in a vertical direction with respect to 31.

The shape and size of the support column 2 can be changed as appropriate. For example, the column part 2 may have a prismatic shape, a cylindrical shape, or other shapes.
The material of the support column 2 may be wood, plastic, or other material, but is softer than the knife, for example, wood or plastic so that the knife 50 is not damaged. Is preferred. When the column portion 2 is formed of a material softer than a kitchen knife such as wood or plastic, the cutting edge 51 of the kitchen knife 50 can be stabbed and locked so that it can be pivoted. Can be cut with a smaller force.

  The cutting edge receiving portion 3 is provided on the front side of the support column 2 so that the cutting edge 51 of the knife 50 can be rotated, and in particular, can be locked so as to be rotatable in the vertical direction with respect to the plate surface 31 of the cutting board 30. If it is, the shape is arbitrary.

For example, as shown in FIGS. 1 to 3, a groove 6 having an appropriate length and an appropriate depth extending in the vertical direction may be provided. If the cutting edge 51 of the knife 50 is inserted into the lower end portion 6a in the groove 6 and locked, the knife 50 can be rotated in the vertical direction with respect to the plate surface 31 of the cutting board 30, that is, the knife 50 is cut by using the cutting edge 51 as a fulcrum. 30 plate surfaces 31 can be rotated in the vertical direction.
At this time, more preferably, as described above, the cutting edge 51 of the kitchen knife 50 is pierced so that it can be pivotably locked, so that the principle of the lever can be used. Can be cut with less force.
In addition, it is preferable that the bottom part of the groove part 6 comprises the board surface 31 of the cutting board 30. FIG.
Further, it is preferable that a plurality of groove portions 6 are provided in the vertical direction so that the groove portion 6 that locks the cutting edge 51 of the knife 50 can be selected depending on the size of the food to be cut.

  Although not shown in the drawing, one or more concave portions having an appropriate shape may be provided on the front surface side of the support column 2 or a plurality thereof may be provided at appropriate intervals in the vertical direction.

The support | pillar part 2 may adhere to the board surface 31 of the cutting board 30, and you may make it attach so that attachment or detachment is possible.
In order to fix the support column 2 to the plate surface 31 of the cutting board 30, it may be fixed with an adhesive or a nail.
Further, a cutting board mounting portion may be provided on the support column 2 so that it can be detachably attached. As the cutting board mounting portion, for example, a clip-like one that fixes the board main body portion of the cutting board from above and below can be exemplified.

The frame part 4 may be provided in an arch shape from the support part 2 to the plate surface 31 of the cutting board 30.
The specific shape of the arch can be changed as appropriate, but when the knife 51 of the knife 50 is locked to the edge receiving portion 3 and the knife 50 is rotated about this as a fulcrum, at least the handle of the knife 50 has a frame portion. It is necessary to form in a shape and size that does not hit 4.

  The frame portion 4 may be, for example, an elongated rod shape, an elongated flat plate shape, or other shapes. Also, the material is arbitrary, and for example, wood, plastic, or other materials may be used, but bamboo is preferred because it can be easily bent.

One end of the frame portion 4 may be fixed to the column portion 2 and the other end may be fixed to the plate surface 31 of the cutting board 30.
In order to fix one end of the frame part 4 to the column part 2, adhesion, nailing, screwing, or any other means may be used.
On the other hand, in order to fix the other end of the frame part 4 to the plate surface 31 of the cutting board 30, adhesion, nail attachment, screw attachment, or any other means may be used. A hole may be provided in the plate surface of the cutting board, and the other end of the frame portion may be inserted into the hole to be locked.

  Note that one end of the frame portion 4 may be attached to the column portion 2 so as to be rotatable in the horizontal direction, and the other end may be formed so as not to be fixed to the plate surface 31 of the cutting board 30 or to be fixed at an appropriate position. .

The guide hole 5 is a groove-shaped through hole into which the blade 52 of the kitchen knife 50 can be inserted and can guide the blade 52 slidably in the length direction of the frame 4. For example, the guide hole 5 is long in the length direction of the frame 4. What is necessary is just to form as a long hole extended to.
This guide hole 5 is preferably provided up to the plate surface 31 of the cutting board 30.

  In addition, you may make it axially stop the support | pillar part 2 to the cutting board 30 so that rotation in a horizontal direction is possible. Thus, if the support | pillar part 2 is axially stopped, a foodstuff can be cut | disconnected by arbitrary directions.

Moreover, the support | pillar part 2 and the flame | frame part 4 as mentioned above can also be provided as a cutting board auxiliary | assistance tool detachably attached to the existing cutting board so that it can attach to the cutting board 30 so that attachment or detachment is possible.
That is, a support column 2 having a cutting edge receiving portion 3 capable of pivotally locking a cutting edge 51 of a knife 50, an arch shape provided from the support column 2, the blade 52 of the knife 50 can be inserted, and The frame portion 4 having the guide hole 5 that can be guided so as to be slid in the vertical direction with respect to the plate surface 31 of the cutting board 30 and the support column portion 2 can be attached to the plate surface 31 of the cutting board 30 in a standing state. It is also possible to provide a cutting board assisting device including a mounting portion.
In this case, the cutting board mounting portion can be exemplified by a clip-like one that holds and fixes the cutting board main body portion from above and below, for example.
