Description

  The present invention relates to a cutting board mainly used for cooking such as bread cutting.

In a cutting board according to the following Patent Document 1, a plurality of partition plates divided from each other are connected by a hinge so as to be foldable.
Japanese Patent Laid-Open No. 10-309239

The cutting board according to Patent Document 1 has the following problems *.
* The folding line is orthogonal to the long side of the cutting board that forms a rectangular shape in the unfolded state and is parallel to the short side, and since each partition plate is rectangular, the folding direction of each partition plate is the same. Thus, the partition plates are folded along the long side of the cutting board, and when the partition plates are folded, the partition plates overlap each other and become bulky.

  * Since hinges are used to connect the partition plates, the connection work between the partition plates becomes cumbersome, and gaps are easily generated between the partition plates due to rattling of the hinges themselves or hinge installation errors. Therefore, usability deteriorates.

* Since the surface of each partition plate is flat, a part of the cutting waste is easily scattered. Therefore, usability deteriorates.
An object of the present invention is to improve the usability of a cutting board by making each partition plate less bulky when each partition plate is folded .

With the aid of code below the embodiment of the drawings (FIGS. 1-9) that describes the present invention.

This cutting board includes a plurality of partition plates 1, 2, and 3 having front and back both surfaces 4 and 5 in the thickness direction Z and outer peripheral surfaces 6 between outer peripheral edges 4a and 5a of the front and back surfaces 4 and 5, respectively. The outer peripheral edges 4a and 5a of the partition plates 1, 2, 2 and 3 adjacent to each other among the drawing plates 1, 2, and 3 are connected to each other by the folding connecting portion 7, and the partition plates 1, 2, and 3 are adjacent to each other. An unfolded state in which the outer peripheral surfaces 6 of the two partition plates 1, 2, 2, 3 are opposed to each other so that the front surfaces 4 of the partition plates 1, 2, 3 are aligned with each other and the back surfaces 5 of the partition plates 1, 2, 3 are aligned with each other P and at least one pair of partition plates 1, 2, 2, and 3 among the partition plates 1, 2, 2, and 3 adjacent to each other by the partition plates 1, 2, and 3 are folded together by a fold connection portion 7. Then, the folded state Q in which the back surfaces 5 of the partition plates 1, 2, 2, 3 are opposed to each other is taken.
Each partition plate sandwiches the both side partition plates 2 between the central partition plate 1, both side partition plates 2 connected to the central partition plate 1 so as to sandwich the central partition plate 1, and the central partition plate 1. And both end partition plates 3 connected to the both side partition plates 2. The front and back sides 4, 5 of each partition plate 1, 2, 3 are isosceles sides 1b, 1c, 2b, 2c, 3b, 3c extending from the apex portions 1d, 2d, 3d and both isosceles sides 1b, 1c, 2b, 2c. , 3b, 3c, isosceles right triangles surrounded by the bases 1a, 2a, 3a, or isosceles 1b, 1c, 2b, 2c, 3b, 3c extending from the top and both isosceles 1b, 1c , 2b, 2c, 3b, 3c are formed in a trapezoidal shape surrounded by the bases 1a, 2a, 3a.
In the unfolded state P, the apex angle portion 1d or the apex side 1e of the central partition plate 1 is located between the base sides 2a of the side partition plates 2, and the base side 1a of the central partition plate 1 is the apex angle portion 2d of the both side partition plates 2. Alternatively, the folding connecting portion 7 is located between the top sides, and is provided between the isosceles sides 1 b and 1 c of the central partition plate 1 and one of the isosceles sides 2 b and 2 c of the side partition plate 2. The folding connecting portion 7 is provided between the other isosceles 2b, 2c of the side partition plates 2 and the other side 2c and the bottom 3a of the both end partition plates 3, and the apex angle portion 2d or the top side of the side partition plates 2 is the center. It is located between the base 1a of the partition plate 1 and one of the isosceles 3b and 3c of the partition plates 3 at both ends, and the base 2a of the side partition plate 2 is the apex 1d or top of the central partition plate 1. It is located between the side 1e and the other isosceles 3c of the isosceles 3b and 3c of the both-end partition plate 3.

In the invention of claim 1 , each partition plate 1, 2, 3 can be folded in a different folding direction so that the folding state of each partition plate 1, 2, 3 can be changed. Each of the partition plates 1, 2, and 3 becomes less bulky when folded. In addition, the cutting board can be folded into a square shape in the folded state Q so as to be compact, and the partition plates 1, 2, 3 are less bulky when the partition plates 1, 2, 3 are folded. . Further, when the apex corner portion 1d or the apex side 1e of the central partition plate 1 is lifted, both folding connecting portions 7 between the central partition plate 1 and the both side partition plates 2 are caused by the weight of the both side partition plates 2 and the both end partition plates 3. Since both the side partition plates 2 are folded, it becomes easy to fold.

In the invention of claim 5 premised on the invention of any one of claims 1 to 4 , the folding connecting portions are the outer peripheral edges 4 a of both partition plates 1, 2, 2, 3 adjacent to each other. It is the flexible sheet 7 affixed on the back surface 5 of these partition plates 1, 2, 2, and 3 between 5a. The flexible sheet 7 may be divided into a plurality of pieces.

In the invention of claim 5 , since the flexible sheet 7 is used to connect the partition plates 1, 2, 3, it is only necessary to attach the flexible sheet 7 to the back surface 5. The structure is easy, and the flexible sheet 7 closes the partition plates 1, 2, 3, so that a gap is hardly generated between the partition plates 1, 2, 3. The flexible sheet 7 also has a function of preventing slipping by selecting a material. For example, in the invention of claim 5, the flexible sheet 7 is attached to the entire back surface 5 of each partition plate 1, 2, 3. However, the rear surface 5 may be slightly exposed in the vicinity of the outer periphery 9, 10, 11 in the unfolded state P. The flexible sheet 7 may be divided into a plurality of pieces. Therefore, the anti-slip function can be more reliably performed. Further, for example, in the invention of claim 5, the magnet 8 that holds the folded state Q between the back surfaces 5 of the two partition plates 1, 2, 2, 3 folded together by the flexible sheet 7 in the folded state Q. Is concealed by the flexible sheet 7 between the flexible sheet 7 and the back surfaces 5 of the partition plates 1, 2, 3. Therefore, the magnet 8 can be easily attached to the partition plates 1, 2, 3 by the flexible sheet 7.

Incidentally, the depth D of the groove 13 is about 7 mm, and the width W of the groove 13 is about 6 mm.

  When the cooking cutting board is placed on a table or the like in such an unfolded state P, the entire flexible sheet 7 is brought into use in contact with the table or the like. At that time, if the magnet 8 is attracted to a mounting surface such as a table or a storage shelf or a vertical wall surface, the cooking cutting board can be reliably held.

  When the flexible knob 12 is lifted in the unfolded state P of the cooking cutting board, as shown in FIGS. 3 (a) and 3 (b), the central partition plate 1 and the both side partitions are separated by the weight of the both side partition plates 2 and the both end partition plates 3.
