Abstract

PROBLEM TO BE SOLVED: To provide a highly efficient chopping board for pouring a food material directly into a pot by inclining the chopping board, even in the case many stripe-shaped scratches are formed by a kitchen knife on the surface of the copping board, the sliding movements of food materials are hardly blocked by the scratches of the chopping board, and even in the case the opening of a container to receive the food material is relatively narrow, moreover, the food materials can be poured without fail into the container.SOLUTION: In a chopping board, two hinges 6 and 7 are formed, and a central plate portion 8 is formed between the hinges 6 and 7. Two movable plates 9 and 10 are hinged to the two sides of the central plate 8. The two hinges 6 and 7 are so extended at an inclination with respect to the longitudinal direction of the chopping board as to approach the same side edges from the rear ends 15 and 17 of the hinge on the rear end edge 3 of the chopping board to the front ends 16 and 18 of the hinge on the front end edge 2.

Description

本発明は、主に一般家庭で使用されるまな板に関する。   The present invention relates to a cutting board mainly used in general households.

まな板の長さ方向に2つの薄肉ヒンジを形成することによって、中央板部が形成されると共に、その中央板部の両側にそれとヒンジ結合された2つの可動板部が形成されたまな板は従来から存在する。このようなまな板は、野菜等の食材を刻んだ後に可動板部を立ててから、まな板を傾斜させて食材を滑動させ、食材をまな板に載せたまま鍋に投入して加熱調理したり、深皿などに移し替えて生野菜サラダとして盛り付けたりして使用される。その際、まな板の表面を滑動する食材が、可動板部によってまな板の側方からこぼれ落ちることがなく便利である。   By forming two thin-walled hinges in the length direction of the cutting board, a central plate part is formed, and on the both sides of the central plate part, a cutting board in which two movable plate parts hinged to it are formed has been conventionally used. Exists. Such a cutting board is made by chopping ingredients such as vegetables, standing up the movable plate part, tilting the cutting board and sliding the ingredients, putting the ingredients on the cutting board and cooking in a pan, It is used after being transferred to a plate and serving as a raw vegetable salad. At this time, the food that slides on the surface of the cutting board is convenient because the movable plate portion does not spill from the side of the cutting board.

従来のヒンジを有するまな板は、2つのヒンジが、まな板の長手方向に延びる中心線に関し左右対称に形成されているので、まな板の後端縁を体の正面に向かせて自然な状態で両可動板部をそれぞれの手で持ったときに、まな板の中央板部の長手方向の向きは、持つ人の体の正面中央からその人の体の左右どちらの方向にも傾くことなく、体の前方に延びる。ここで、中央板部の長手方向とは、まな板の長手方向と垂直に延びる二本の幅方向の線を取り、それら二本の線がそれぞれ2つのヒンジと交わる交点間の中心を通って延びる直線の方向を言う。従来のヒンジを有するまな板では、前述したように、2つのヒンジが、まな板の長手方向に延びる中心線に関し左右対称に形成されているので、まな板の長手方向と、中央板部の長手方向とは同じ方向である。このようなまな板を使用して刻んだ食材を鍋に投入するときは、鍋を体の正面中央に置き、それぞれの可動板部の手前側の端部すなわち後端部を、左右それぞれの手で体の前に持ち、ヒンジで折り曲げて可動板部を立て、そのまな板を、その前端縁が低くなるように下方に傾斜させる。これにより、食材は、傾斜した中央板部の上をその長手方向に滑動して鍋などに投入される。中央板部の長手方向とまな板の長手方向は同じ方向であるから、食材はまな板の長手方向に対しても平行である。   The cutting board having a conventional hinge is formed so as to be bilaterally symmetric with respect to the center line extending in the longitudinal direction of the cutting board, so that both of the movable boards can be moved in a natural state with the rear edge of the cutting board facing the front of the body. When holding the board part with each hand, the longitudinal direction of the center board part of the cutting board is not tilted in the left or right direction of the person's body from the front center of the person's body. It extends to. Here, the longitudinal direction of the central plate portion takes two lines in the width direction extending perpendicularly to the longitudinal direction of the cutting board, and these two lines respectively extend through the center between the intersections where the two hinges intersect. Say the direction of a straight line. In a cutting board having a conventional hinge, as described above, since the two hinges are formed symmetrically with respect to the center line extending in the longitudinal direction of the cutting board, the longitudinal direction of the cutting board and the longitudinal direction of the central plate portion are The same direction. When putting chopped ingredients using such a cutting board into the pan, place the pan in the center of the front of the body, and use the left and right hands to move the front end or rear end of each movable plate. Hold it in front of your body, fold it with a hinge to stand up the movable plate, and tilt the cutting board downward so that its front edge is lowered. Thereby, foodstuffs are slid on the inclined center board part in the longitudinal direction, and are thrown into a pot etc. Since the longitudinal direction of the central plate portion and the longitudinal direction of the cutting board are the same direction, the foodstuff is parallel to the longitudinal direction of the cutting board.

食材を鍋に投入するときは、食材の滑動する方向が、まな板を持つ人の体の正面から左右どちらの方向にも傾かないようにすることが、作業を自然な状態で行うために必要である。仮に、鍋を体の正面の中心から左右いずれかに離して置いた場合は、食材を斜めに滑動させて鍋に投入することになるが、その場合、手に持ったまな板を手首を折り曲げて左右いずれかに傾けなければならず、不自然な状態でまな板を持つことになる。そのような不自然な状態でまな板を下方に傾斜させると、両手の左右の手首の状態が対称でないので、手首などに負担がかかり円滑な作業ができない。また、食材が斜めに滑動する場合には、滑動する食材の投入方向が不確定となり、鍋や深皿に投入する作業を円滑に行うことができない。したがって、鍋が体の正面の中央からある程度ずれている場合には、作業者は、自然に体を鍋の方に向かせるのである。すなわち、作業者は、無意識に体の正面を鍋の方向に向かせるのである。したがって、いずれの場合にも、食材は、中央板部の上をその長手方向前方斜め下方に滑動して鍋に投入され、まな板の長手方向にも平行に滑動することになる。 When putting food ingredients into the pan, it is necessary to ensure that the sliding direction of the food ingredients does not tilt to the left or right from the front of the person holding the cutting board. is there. If the pan is left or left from the center of the front of the body, the ingredients are slid diagonally and put into the pan, but in that case, fold a wrist with a chopping board in your hand. You have to tilt it left or right, and you will have a cutting board in an unnatural state. If the cutting board is tilted downward in such an unnatural state, the wrists on both the left and right wrists are not symmetrical, and the wrist is burdened and smooth work cannot be performed. Moreover, when foodstuff slides diagonally, the input direction of the foodstuff to slide becomes uncertain, and the operation | work put into a pan or a deep dish cannot be performed smoothly. Therefore, when the pan is somewhat deviated from the center of the front of the body, the worker naturally turns the body toward the pan. That is, the worker unconsciously turns the front of the body toward the pan. Therefore, in any case, the foodstuff slides on the central plate portion diagonally forward and downward in the longitudinal direction and is put into the pan, and also slides in parallel with the longitudinal direction of the cutting board.

ところで、ヒンジを有するまな板は、合成樹脂で形成されているので、包丁の刃先によってまな板の長手方向と垂直な筋状の傷が生じることは避けられない。特に、まな板の中央板部にほとんどの傷が生じる。前述したように、従来品は、まな板の長手方向と、中央板部の長手方向は同じ方向に延びているから、まな板の傷は、中央板部の長手方向に垂直に延びている。まな板の使用期間が短いときは、まな板の表面は傷などが少ないので、刻まれた食材が中央板部の上を円滑に滑動して鍋などに投入される。しかし、長期間使用すると包丁の刃先で多数の傷が生じ、しかも、その傷の方向は食材が滑動する方向である中央板部の長手方向に垂直である。筋状の傷の方向と食材の滑動する方向が垂直をなすので、食材は筋状の傷に引っ掛かり易く円滑な滑動が阻害されるのである。この結果、投入しようとした食材がまな板の表面の傷に引っ掛かるようにして残るので、それを手で落とさなければならない。加熱料理中の鍋に食材を投入する場合は、まな板に付着している食材を手で滑り落とすときに、鍋から湧き上がる高温の蒸気が手に当たり、火傷する虞もある。   By the way, since the cutting board having a hinge is made of synthetic resin, it is inevitable that a streak-like scratch perpendicular to the longitudinal direction of the cutting board is caused by the blade edge of the knife. In particular, most scratches occur in the central plate portion of the cutting board. As described above, in the conventional product, since the longitudinal direction of the cutting board and the longitudinal direction of the central plate portion extend in the same direction, the scratches on the cutting board extend perpendicularly to the longitudinal direction of the central plate portion. When the cutting board is used for a short period of time, the surface of the cutting board is less scratched, so that the engraved food material slides smoothly on the center board and is put into a pan or the like. However, when used for a long period of time, a number of scratches are generated at the knife edge, and the direction of the scratches is perpendicular to the longitudinal direction of the central plate, which is the direction in which the food material slides. Since the direction of the line-shaped wound and the direction in which the food material slides are perpendicular to each other, the food material is easily caught by the line-shaped wound and smooth sliding is hindered. As a result, the food to be thrown in remains so as to be caught by scratches on the surface of the cutting board, which must be dropped by hand. When food is put into a pan during cooking, when the food adhering to the cutting board is slid down by hand, there is a risk of hot steam rising from the pan hitting the hand and causing burns.

また、刻んだ野菜を深皿に移し替えて生野菜サラダとして盛り付ける場合、深皿の開口は調理用の鍋の開口よりも小さいので、野菜を深皿に投入する際に野菜が深皿の開口から外れて、深皿の周囲に落ちてしまう虞がある。これは、開口の小さな鍋に食材を投入する場合も同様である。   Also, if you transfer the chopped vegetables to a deep dish and serve them as a raw vegetable salad, the opening of the deep dish is smaller than the opening of the cooking pan, so when you put the vegetables into the deep dish, the vegetables will open in the deep dish. There is a risk that it will fall off and fall around the deep dish. The same applies to the case where food is put into a small opening pan.

本発明は、まな板上で刻んだ食材を、まな板の前端縁が低くなるようにまな板を傾けて直接食材を鍋に投入するまな板であって、まな板を長期間使用してまな板の表面に包丁の刃による筋状の傷が生じた場合であっても、刻んだ食材の滑動がまな板の傷に阻害されにくく、食材を投入する容器の開口が比較的狭いものであっても、刻んだ食材を容器に確実に投入することができ得る、作業効率の良いまな板を提供することを課題とする。   The present invention is a cutting board in which ingredients chopped on a cutting board are directly put into a pan by tilting the cutting board so that the front edge of the cutting board is lowered, and the cutting board is used on the surface of the cutting board for a long time. Even if a streak is caused by a blade, the chopped food is not easily obstructed by the scratches on the cutting board, and the chopped food can be used even if the opening of the container into which the food is put is relatively narrow. It is an object of the present invention to provide a cutting board with high work efficiency that can be reliably put into a container.

請求項1記載の発明は、前端縁、後端縁及び一対の側縁を有し、2つのヒンジが形成され、それら2つのヒンジによりそれらの間に中央板部が形成されると共に、該中央板部の両側にそれとヒンジ結合された2つの可動板部が形成されたまな板であって、第一のヒンジは、後端縁から前端縁に至るまで延びており、第二のヒンジは、後端縁、前端縁及び側縁のいずれか1つの縁から残りのいずれか1つの縁に至るまで延びており、後端縁から前端縁に向かう方向をまな板の長手方向としたときに、少なくとも1つのヒンジは、その後端から前端に向かうに従って、一方の側縁に近づく方向にまな板の長手方向に対し傾斜して延びており、他の1つのヒンジは、その後端から前端に向かうに従って、まな板の長手方向に対し前記一方の側縁に近づく方向に0度以上の角度を以って延びている構成である。   The invention according to claim 1 has a front edge, a rear edge, and a pair of side edges, two hinges are formed, a central plate portion is formed between the two hinges, and the center A cutting board in which two movable plate portions hinged to the plate portion are formed on both sides of the plate portion.

Close to the one side edge in the longitudinal direction Ku is configured to extend drives out angle greater than 0 ° direction.

請求項2記載の発明は、双方のヒンジの後端がまな板の後端縁上にあるときは、まな板の中央板部に係る部分の後端縁の中心は、まな板の後端縁の中心から偏倚している構成である。   In the invention according to claim 2, when the rear ends of both hinges are on the rear end edge of the cutting board, the center of the rear end edge of the portion related to the central plate portion of the cutting board is from the center of the rear end edge of the cutting board. It is a biased configuration.

請求項3記載の発明は、中央板部に係る部分の後端縁から延びるハンドルが設けられている構成である。   The invention described in claim 3 is a configuration in which a handle extending from the rear end edge of the portion related to the central plate portion is provided.

請求項4記載の発明は、ハンドル自身の長手方向前方に延びる中心線が、まな板の長手方向に対して傾斜している構成である。   The invention according to claim 4 is configured such that a center line extending forward in the longitudinal direction of the handle itself is inclined with respect to the longitudinal direction of the cutting board.

請求項5記載の発明は、2つのヒンジが、共にまな板の後端縁上におけるヒンジの後端から前端縁上におけるヒンジの前端まで、それぞれ同じ側縁に近づくようにまな板の長手方向に対し傾斜して延びている構成である。 The invention according to claim 5 is characterized in that the two hinges are inclined with respect to the longitudinal direction of the cutting board so as to approach the same side edge from the rear end of the hinge on the rear end edge of the cutting board to the front end of the hinge on the front end edge. It is the composition extended.

請求項6記載の発明は、まな板の、少なくとも1つの可動板部に係る部分の後端縁から、摘み部が突出するように設けられている構成である。   The invention according to claim 6 is a configuration in which the knob portion is provided so as to protrude from the rear end edge of the portion of the cutting board related to the at least one movable plate portion.

請求項7記載の発明は、摘み部の、可動板部に対する付け根の一方の端部が、ヒンジの後端と位置を同じくする構成である。   The invention according to claim 7 is configured such that one end portion of the base of the knob portion with respect to the movable plate portion has the same position as the rear end of the hinge.

請求項1記載の発明は、まな板に2つのヒンジが形成され、少なくとも1つのヒンジが、その後端から前端に向かうに従って、一方の側縁に近づく方向にまな板の長手方向に対し傾斜して延びており、他の1つのヒンジが、その後端から前端に向かうに従って、まな板の長手方向に対し前記一方の側縁に近づく方向に0度以上の角度を以って延びている。前述したように、中央板部の長手方向とは、まな板の長手方向と垂直に延びる二本の幅方向の線を取り、それら二本の線がそれぞれ2つのヒンジと交わる交点間の中心を通って延びる直線の方向を言うので、本発明のまな板は、中央板部の長手方向がまな板の長手方向に対して傾斜する。そして、前述したように、食材を鍋に投入するときは、食材の滑動する方向が、まな板を持つ人の体の正面から左右どちらの方向にも傾かないようにすることが、作業を自然な状態で行うために必要である。刻んだ食材は立てた可動板部の間の中央板部の上を滑動するから、最も効率的に食材を鍋に投入するためには、食材の滑動する方向は中央板部の長手方向と同じとすることが自然である。したがって、必然的に、作業者は、食材の滑動する方向である中央板部の長手方向を、まな板を持つ人の体の正面から左右どちらの方向にも傾かないようにして食材を滑動させて鍋に投入する。このようにして投入する場合、食材は、中央板部に付いている筋状の傷に対して傾斜した状態でまな板の上を滑動する。そうすると、滑動している食材は筋状の傷に対して垂直ではなく斜めに引っ掛かるので、筋状の傷が食材に与える抵抗は、食材が傷と垂直に滑動している場合よりも弱くなり、従来品よりも食材の滑動が円滑に行われる。 According to the first aspect of the present invention, two hinges are formed on the cutting board, and at least one hinge extends incline with respect to the longitudinal direction of the cutting board in a direction approaching one side edge from the rear end toward the front end. The other hinge extends from the rear end toward the front end with an angle of 0 degrees or more in a direction approaching the one side edge with respect to the longitudinal direction of the cutting board. As described above, the longitudinal direction of the central plate portion takes two lines in the width direction extending perpendicular to the longitudinal direction of the cutting board, and these two lines pass through the center between the intersections where the two hinges intersect each other. In the cutting board according to the present invention, the longitudinal direction of the central plate portion is inclined with respect to the longitudinal direction of the cutting board. And as mentioned above, when food is put into the pan, it is natural that the direction in which the food slides does not tilt in the left or right direction from the front of the body of the person holding the cutting board. Needed to do in state. Since the chopped food material slides on the central plate part between the standing movable plate parts, in order to put the food material into the pan most efficiently, the sliding direction of the food material is the same as the longitudinal direction of the central plate part. Is natural. Therefore, the operator inevitably slides the food so that the longitudinal direction of the central plate portion, which is the direction in which the food slides, does not tilt in the left or right direction from the front of the body of the person holding the cutting board. Put in the pan. When throwing in this way, a foodstuff slides on a cutting board in the state inclined with respect to the streak-like wound attached to the center board part. Then, since the sliding food is hooked diagonally rather than perpendicular to the streak, the resistance that the streak gives to the food becomes weaker than when the food is sliding perpendicular to the wound, The sliding of the food is performed more smoothly than the conventional product.

請求項2記載の発明は、双方のヒンジの後端がまな板の後端縁上にあるときは、まな板の中央板部に係る部分の後端縁の中心は、まな板の後端縁の中心から偏倚している。前述したように、中央板部の長手方向の中心線は、まな板の長手方向の中心線に対して傾斜しているから、仮に、中央板部に係る部分の後端縁の中心が、まな板の後端縁の中心と同じ位置にあるときは、中央板部全体がまな板の一方の側に寄り過ぎるので、双方の中心をずらすことにより中央板部をまな板の中央寄りに配置させることができる。 In the invention according to claim 2, when the rear ends of both hinges are on the rear end edge of the cutting board, the center of the rear end edge of the portion related to the central plate portion of the cutting board is from the center of the rear end edge of the cutting board. It is biased. As described above, since the center line in the longitudinal direction of the central plate portion is inclined with respect to the center line in the longitudinal direction of the cutting board, the center of the rear edge of the portion related to the central plate portion is assumed to be the cutting board. When it is at the same position as the center of the rear edge, the entire central plate portion is too close to one side of the cutting board, so that the central plate portion can be arranged closer to the center of the cutting board by shifting both centers.

請求項3記載の発明は、中央板部に係る部分の後端縁から延びるハンドルが設けられている。ハンドルは中央板部に係る部分の後端縁から延びているので、ハンドルを握ることにより安定した状態でまな板を持つことができる。 The invention according to claim 3 is provided with a handle extending from the rear end edge of the portion related to the central plate portion. Since the handle extends from the rear end edge of the portion related to the central plate portion, the cutting board can be held in a stable state by grasping the handle.

請求項4記載の発明は、ハンドル自身の長手方向前方に延びる中心線が、まな板の長手方向に対して傾斜している。ハンドルの方向がこのように設定されているまな板は斬新であって、購買者の注意を惹き、購買意欲を刺激することができる。 In the invention according to claim 4, the center line extending forward in the longitudinal direction of the handle itself is inclined with respect to the longitudinal direction of the cutting board. The cutting board with the handle direction set in this way is novel and can attract the buyer's attention and stimulate their willingness to purchase.

請求項5記載の発明は、2つのヒンジが、共にまな板の後端縁上におけるヒンジの後端から前端縁上におけるヒンジの前端まで、それぞれ同じ側縁に近づくようにまな板の長手方向に対し傾斜して延びている。したがって、双方の可動板部は、共に中央板部の後端から前端に至るまで存在することになるから、刻んだ食材を鍋に投入する方向に滑動させるときに、食材が中央板部の前端縁から鍋に投入されるまで食材が側方にこぼれ落ちることを防止することができる。また、食材投入時における中央板部の前端縁は鍋に対して傾斜し、中央板部の前端縁の一方の端部は他方の端部よりも前方へ突き出る。食材の投入時に、まな板を、その突き出た中央板部の端部側のヒンジが他方のヒンジよりも低くなるように傾けると、食材はまな板の低い方に移動しながらその突き出た部分から食材が投入されるので、食材は狭い範囲で滑動しながら鍋に投入される。したがって、鍋の開口が狭くても食材がその開口から外れることなく確実に鍋に投入することができる。   The invention according to claim 5 is characterized in that the two hinges are inclined with respect to the longitudinal direction of the cutting board so as to approach the same side edge from the rear end of the hinge on the rear end edge of the cutting board to the front end of the hinge on the front end edge. And extended. Therefore, since both the movable plate parts exist from the rear end to the front end of the central plate portion, when the chopped food material is slid in the direction to put into the pan, the food material is moved to the front end of the central plate portion. The food can be prevented from spilling to the side until it is put into the pan from the edge. Further, the front end edge of the central plate portion at the time of feeding the food is inclined with respect to the pan, and one end portion of the front end edge of the central plate portion protrudes forward from the other end portion. If the cutting board is tilted so that the hinge on the end of the protruding central plate is lower than the other hinge when the food is added, the food moves from the protruding part while moving to the lower side of the cutting board. Since it is thrown in, the ingredients are thrown into the pan while sliding within a narrow range. Therefore, even if the opening of the pan is narrow, the foodstuff can be reliably put into the pan without coming off the opening.

請求項6記載の発明は、まな板の、少なくとも1つの可動板部に係る部分の後端縁から、摘み部が突出するように設けられている。したがって、まな板の広範囲において食材を刻んだときであっても、摘み部を摘まんで可動板部を立てれば、指がまな板の表面に触れず、指が刻まれた食材に触れたり食材から出る水分で濡れたりすることがない。   The invention according to claim 6 is provided such that the knob portion protrudes from the rear end edge of the portion of the cutting board related to the at least one movable plate portion. Therefore, even when food is chopped over a wide area of the cutting board, if the movable plate part is raised by picking the knob, the finger does not touch the surface of the cutting board, but the finger touches the food that is engraved or the moisture that comes from the food It won't get wet.

請求項7記載の発明は、摘み部の、可動板部に対する付け根の一方の端部が、ヒンジの後端と位置を同じくする。したがって、摘み部を掴んで可動板部を回動させながら折り曲げるときに、摘み部と可動板部の回動中心が同じ位置にあるから、回動を無理なく行うことができる。   According to the seventh aspect of the present invention, one end of the base of the knob with respect to the movable plate has the same position as the rear end of the hinge. Therefore, when the knob is gripped and bent while the movable plate is rotated, the rotation centers of the knob and the movable plate are at the same position, so that the rotation can be performed without difficulty.

次に、本発明の実施態様について説明する。まな板1は、前端縁2、後端縁3及び一対の側縁4,5を有している。前端縁2及び後端縁3は直線をなすが、両側縁4,5はそれぞれ外側に凸の緩やかな弧状をなしている。また、まな板1には、後端縁3から前端縁2に至るまで延びる第一のヒンジ6と第二のヒンジ7が形成されている。2つのヒンジ6,7が形成されることにより、それらの間に中央板部8が形成されると共に、その中央板部8の両側にそれとヒンジ結合された2つの可動板部9,10が形成される。両可動板部9,10はヒンジ6,7を回動中心として、中央板部8に対してそれぞれ回動可能である。図4に示すように、第一のヒンジ6は、まな板1の底面11にV溝12を設け、まな板1の上面14に浅溝25を設けることにより形成されている。第二のヒンジ7は、同じくまな板1の底面11にV溝13を設け、まな板1の上面14に浅溝34を設けることにより形成されている。したがって、いずれの可動板部9,10も、まな板1の上面14側に回動させることができる。まな板1は、ポリプロピレンの射出成形により形成されるが、材料及び製造方法がこれに限定されるものではない。   Next, embodiments of the present invention will be described. The cutting board 1 has a front end edge 2, a rear end edge 3, and a pair of side edges 4 and 5. The front end edge 2 and the rear end edge 3 form a straight line, but the side edges 4 and 5 each have a gentle arc shape protruding outward. Further, the cutting board 1 is formed with a first hinge 6 and a second hinge 7 extending from the rear end edge 3 to the front end edge 2. By forming the two hinges 6, 7, a central plate portion 8 is formed between them, and two movable plate portions 9, 10 hinged to the central plate portion 8 are formed on both sides of the central plate portion 8. Is done. Both movable plate portions 9 and 10 are rotatable with respect to the central plate portion 8 with the hinges 6 and 7 as the rotation centers. As shown in FIG. 4, the first hinge 6 is formed by providing a V groove 12 on the bottom surface 11 of the cutting board 1 and providing a shallow groove 25 on the upper surface 14 of the cutting board 1. Similarly, the second hinge 7 is formed by providing a V groove 13 on the bottom surface 11 of the cutting board 1 and providing a shallow groove 34 on the upper surface 14 of the cutting board 1. Therefore, any of the movable plate portions 9 and 10 can be rotated toward the upper surface 14 side of the cutting board 1. The cutting board 1 is formed by injection molding of polypropylene, but the material and manufacturing method are not limited to this.

第一のヒンジ6は、その後端15から前端16に向かうに従って一方の側縁5に近づく方向に延びており、まな板1の長手方向に対して傾斜している。また、第二のヒンジ7も、その後端17から前端18に向かうに従って一方の側縁5に近づく方向に延びており、この第二のヒンジ7もまな板1の長手方向に対して傾斜している。第一のヒンジ6の、まな板1の長手方向に対する傾斜角は約8度であり、第二のヒンジ7の傾斜角は約14度であるが、本発明がこの数値に限定されないことは勿論である。双方のヒンジ6,7の傾斜角が同一であってもよい。また、双方のヒンジ6,7のいずれか1つが、まな板1の長手方向に対して傾斜せず、平行であってもよい。ヒンジ6,7がこのように形成されることによって、中央板部8の幅は前方に行くに従って広がる形状となる。   The first hinge 6 extends in a direction approaching one of the side edges 5 from the rear end 15 toward the front end 16, and is inclined with respect to the longitudinal direction of the cutting board 1. The second hinge 7 also extends in a direction approaching one side edge 5 from the rear end 17 toward the front end 18, and the second hinge 7 is also inclined with respect to the longitudinal direction of the cutting board 1. . The inclination angle of the first hinge 6 with respect to the longitudinal direction of the cutting board 1 is about 8 degrees, and the inclination angle of the second hinge 7 is about 14 degrees. Of course, the present invention is not limited to this value. is there. The inclination angles of the hinges 6 and 7 may be the same. Further, any one of the hinges 6 and 7 may be parallel to the longitudinal direction of the cutting board 1 without being inclined. By forming the hinges 6 and 7 in this way, the width of the central plate portion 8 becomes a shape that widens toward the front.

第一のヒンジ6と第二のヒンジ7は、共に前方に行くに従って一方の側縁5に近づくように、まな板1の長手方向に対して傾斜しているので、両ヒンジ6,7の間に形成される中央板部8の長手方向もまな板1の長手方向に対して傾斜している。前述したように、中央板部8の長手方向とは、まな板1の長手方向と垂直に延びる二本の幅方向の線を取り、それら二本の線がそれぞれ2つのヒンジ6,7と交わる交点間の中心を通って延びる直線の方向を言う。すなわち、図1に示すように、まな板1の長手方向に垂直に延びる幅方向の線、例えばある地点の幅方向線Yと、第一のヒンジ6及び第二のヒンジ7との交点19,20間の中心21、それ以外のある地点の幅方向線Zと、第一のヒンジ6及び第二のヒンジ7との交点22,23間の中心24の2つの中心21,24を結んだ直線を、中央板部8の長手方向中心線Xとすると、その長手方向中心線Xの方向が、中央板部8の長手方向となる。   Since both the first hinge 6 and the second hinge 7 are inclined with respect to the longitudinal direction of the cutting board 1 so as to approach one side edge 5 as going forward, the first hinge 6 and the second hinge 7 are between the hinges 6 and 7. The longitudinal direction of the formed central plate portion 8 is also inclined with respect to the longitudinal direction of the cutting board 1. As described above, the longitudinal direction of the central plate portion 8 takes two lines in the width direction extending perpendicularly to the longitudinal direction of the cutting board 1, and the intersection points where the two lines intersect with the two hinges 6 and 7, respectively. The direction of a straight line extending through the center between. That is, as shown in FIG. 1, intersecting points 19 and 20 of a width direction line extending perpendicularly to the longitudinal direction of the cutting board 1, for example, a width direction line Y at a certain point, and the first hinge 6 and the second hinge 7. A straight line connecting two centers 21, 24, a center direction 21 between the center 21 between them and a width direction line Z at some other point and the intersections 22, 23 between the first hinge 6 and the second hinge 7. Assuming that the longitudinal center line X of the central plate portion 8 is the longitudinal direction center line X, the longitudinal direction of the central plate portion 8 becomes the longitudinal direction.

まな板1は、ハンドル26を有している。図1に示すように、ハンドル26は、まな板1の中央板部8に係る部分の後端縁3に一体に形成されている。ハンドル26の長手方向に延びる中心線は、中央板部8の長手方向中心線Xと一致しており、ハンドル26はまな板1の長手方向に対して傾斜するように形成されている。また、ハンドル26は、ほぼ円形の把持部27と、それよりも幅狭の首部28とから成る。ハンドル26を握ってまな板1を持つときは、把持部27を手の平で包み、親指と人差し指とで首部28を握ることにより、まな板1を確実に持つことができ、ハンドル26を滑らせてまな板1を落とすことがない。また、図3に示すように、ハンドル26は後方に行くに従って滑らかに徐々に上昇するように曲がっている。これにより、調理台に載せられているまな板1のハンドル26を容易につかむことができる。なお、符号32は、吊り下げ用の孔である。   The cutting board 1 has a handle 26. As shown in FIG. 1, the handle 26 is formed integrally with the rear end edge 3 of the portion related to the central plate portion 8 of the cutting board 1. The center line extending in the longitudinal direction of the handle 26 coincides with the longitudinal center line X of the central plate portion 8, and the handle 26 is formed to be inclined with respect to the longitudinal direction of the cutting board 1. The handle 26 includes a substantially circular gripping portion 27 and a narrower neck portion 28. When holding the cutting board 1 by grasping the handle 26, the cutting part 1 can be held securely by wrapping the gripping part 27 with the palm and grasping the neck part 28 with the thumb and forefinger. Will not drop. Further, as shown in FIG. 3, the handle 26 is bent so as to rise smoothly and gradually as it goes rearward. Thereby, the handle 26 of the cutting board 1 mounted on the cooking table can be easily grasped. In addition, the code | symbol 32 is a hole for suspension.

まな板1の、双方の可動板部9,10に係る部分の後端縁3に、まな板1の後方に延びる摘み部30,31が一体に形成されている。それぞれの可動板部9,10を双方の手でつかむことにより、両ヒンジ6,7を中心として可動部9,10を回動し立てることができる。一方の摘み部30の付け根、すなわち摘み部30と可動板部9との境界線(符号は付さず。)の中央板部8寄りの端部は、第一のヒンジ6の後端15と位置を同じくしている。また、他方の摘み部31の付け根、すなわち摘み部31と可動板部10との境界線(符号は付さず。)の中央板部8寄りの端部は、第二のヒンジ7の後端17と位置を同じくしている。したがって、それぞれの摘み部30,31を掴んで可動板部9,10を回動させながら折り曲げるときに、摘み部30,31と可動板部9,10の回動中心が同じ位置にあるから、回動を無理なく行うことができる。また、まな板1の可動板部9に係る部分の後端縁(符号は付さず。)の長さと、その後端縁から突出する摘み部30の付け根の長さは同一である。これに対して、まな板1の可動板部10に係る部分の後端縁13(摘み部31との境界も含む。)の長さは、この後端縁13から突出する摘み部31の付け根の長さよりも長い。   Knob portions 30 and 31 extending rearward of the cutting board 1 are integrally formed on the rear end edge 3 of the cutting board 1 relating to both the movable plate portions 9 and 10. By grasping the respective movable plate portions 9 and 10 with both hands, the movable portions 9 and 10 can be turned upright about the hinges 6 and 7. The base of one knob 30, that is, the end of the boundary between the knob 30 and the movable plate 9 (the reference numeral is not attached) near the center plate 8 is the rear end 15 of the first hinge 6. The position is the same. Further, the base of the other knob 31, that is, the end of the boundary between the knob 31 and the movable plate 10 (the reference numeral is not attached) near the center plate 8 is the rear end of the second hinge 7. 17 and the same position. Therefore, when the gripping portions 30 and 31 are gripped and bent while the movable plate portions 9 and 10 are rotated, the rotation centers of the knob portions 30 and 31 and the movable plate portions 9 and 10 are at the same position. The rotation can be performed without difficulty. Further, the length of the rear edge (not denoted by reference numeral) of the portion of the cutting board 1 relating to the movable plate portion 9 is the same as the length of the root of the knob portion 30 protruding from the rear edge. On the other hand, the length of the rear edge 13 (including the boundary with the knob 31) of the portion of the cutting board 1 relating to the movable plate 10 is the root of the knob 31 protruding from the rear edge 13. Longer than the length.

次に、本実施態様のサイズについて説明する。まな板1の前端縁2から後端縁3までの長さは約295mmであり、ハンドル26を含めたまな板1の全長は約338mmである。弧状に延びる両側縁4,5間の最大幅であるまな板1の最大幅は約225mmである。弧状に延びる側縁4上で長手方向に延びる接線と、第一のヒンジ6の前端16との間の距離は約76mmである。弧状に延びる側縁5上で長手方向に延びる接線と、第二のヒンジ7の前端18との間の距離は約31mmである。したがって、中央板部8に係る部分の前端縁2の長さ、すなわち第一のヒンジ6の前端16と、第二のヒンジ7の前端18間の長さは約118mmである。また、弧状に延びる側縁4上で長手方向に延びる接線と、第一のヒンジ6の後端15との間の距離は約33mmである。弧状に延びる側縁5上で長手方向に延びる接線と、第二のヒンジ7の後端17との間の距離は約110mmである。したがって、中央板部8に係る部分の後端縁3の長さ、すなわち第一のヒンジ6の後端15と、第二のヒンジ7の後端17間の長さは約82mmである。まな板1の後端縁3の中心に対して、中央板部8に係る部分の後端縁の中心は約40mmずれている。摘み部30は後方に行くに従って幅狭となるように形成され、可動板部9との境界が最も幅が広く約29mmである。摘み部31の主体部は、幅が均一であってその幅は約35mmである。また、まな板1の厚みは約4.5mmである。両ヒンジ6,7を構成するV溝12,13の深さは約3.6mmであり、したがって、両ヒンジ6,7の厚みは共に0.9mmである。サイズは以上の通りであるが、本発明がこれらの数値に限定されないことは勿論である。   Next, the size of this embodiment will be described. The length from the front edge 2 to the rear edge 3 of the cutting board 1 is about 295 mm, and the total length of the cutting board 1 including the handle 26 is about 338 mm. The maximum width of the cutting board 1 which is the maximum width between the side edges 4 and 5 extending in an arc is about 225 mm. The distance between the tangent extending longitudinally on the arcuate side edge 4 and the front end 16 of the first hinge 6 is approximately 76 mm. The distance between the tangent extending in the longitudinal direction on the arcuate side edge 5 and the front end 18 of the second hinge 7 is about 31 mm. Therefore, the length of the front end edge 2 of the portion related to the central plate portion 8, that is, the length between the front end 16 of the first hinge 6 and the front end 18 of the second hinge 7 is about 118 mm. The distance between the tangent extending in the longitudinal direction on the side edge 4 extending in an arc shape and the rear end 15 of the first hinge 6 is about 33 mm. The distance between the tangent extending in the longitudinal direction on the arcuate side edge 5 and the rear end 17 of the second hinge 7 is about 110 mm. Therefore, the length of the rear end edge 3 of the portion related to the central plate portion 8, that is, the length between the rear end 15 of the first hinge 6 and the rear end 17 of the second hinge 7 is about 82 mm. The center of the rear end edge of the portion related to the central plate portion 8 is deviated from the center of the rear end edge 3 of the cutting board 1 by about 40 mm. The knob portion 30 is formed so as to become narrower as it goes rearward, and the boundary with the movable plate portion 9 is the widest and is about 29 mm. The main part of the knob 31 has a uniform width and a width of about 35 mm. Moreover, the thickness of the cutting board 1 is about 4.5 mm. The depth of the V-grooves 12 and 13 constituting both the hinges 6 and 7 is about 3.6 mm. Therefore, the thickness of both the hinges 6 and 7 is 0.9 mm. Although the size is as described above, it is needless to say that the present invention is not limited to these numerical values.

次に、本発明の使用方法について説明する。通常の使用方法は、食材を刻み終えたら、図6に示すように、ハンドル26を手前に向けて両摘み部30,31をそれぞれの手で摘み、双方のヒンジ6,7を中心に可動板部9,10を回動させながら立てる。その場合、中央板部8は水平状態に保つ。次いで、食材を投入しようとする鍋の上方に中央板部8の前端縁2を位置させ、その前端縁2を下げてまな板1が前方向に下がるように傾斜させる。自然な状態で両摘み部30,31をそれぞれの手で持ったときに、中央板部8の長手方向の向きは、持つ人の体の正面中央から持つ人の体の左右どちらの方向にも傾くことなく、体の前方に延びる。これにより、食材は中央板部8の上をその長手方向に滑動しながら鍋に投入される。矢印33は中央板部8の長手方向を示したものであり、食材はこの矢印33と同じ方向に滑動する。図6から明らかなように、矢印33はまな板1の表面に生じている傷29に対して傾斜しているので、食材は傷29に対し傾斜した状態で滑動するから、食材が傷29に引っ掛かりづらく円滑に鍋に投入することができる。   Next, the usage method of this invention is demonstrated. As shown in FIG. 6, the normal usage method is that when the food is finished, the handle 26 is directed toward the front, both the knobs 30 and 31 are picked by the respective hands, and the movable plate is centered on both hinges 6 and 7. Standing while rotating the parts 9 and 10. In that case, the central plate portion 8 is kept in a horizontal state. Next, the front end edge 2 of the central plate portion 8 is positioned above the pan where the ingredients are to be added, and the front end edge 2 is lowered so that the cutting board 1 is inclined downward. When holding both knobs 30 and 31 with their respective hands in the natural state, the longitudinal direction of the central plate 8 is in the left or right direction of the person's body from the front center of the person's body. Extends forward of the body without tilting. Thereby, foodstuffs are thrown into a pan, sliding on the center board part 8 in the longitudinal direction. An arrow 33 indicates the longitudinal direction of the central plate portion 8, and the food material slides in the same direction as the arrow 33. As is clear from FIG. 6, since the arrow 33 is inclined with respect to the scratch 29 generated on the surface of the cutting board 1, the food material slides in a state inclined with respect to the scratch 29, so that the food material is caught by the scratch 29. It can be put into the pan smoothly and smoothly.

次に、投入しようとする鍋の開口が狭い場合の使用法について図5を参照しながら説明する。従来のヒンジを有するまな板は、鍋の開口が狭いと、投入しようとした食材が開口から外れて鍋に投入されない。そこで、この実施形態では、食材を刻み終えたら、まず、可動板部9,10を立てる。次に、左側の第二のヒンジ7の前端18が、食材を投入しようとする鍋の開口の中央付近に位置するように、まな板1をわずかに右側に動かす。次に、左側の第二のヒンジ7が右側の第一のヒンジ6よりも低くなるようにまな板1を傾ける。これにより、食材は第二のヒンジ7側に寄る。寄らない場合は、包丁や手を使って寄せる。次いで、まな板1の前端縁2が後端縁3よりも低くなるようにまな板1を傾ける。この場合、第二のヒンジ7の前端18が鍋の開口を超える程度までまな板1を鍋に近づける。そうすると、食材はやや左側に寄った状態で鍋に投入される。この場合も、中央板部の長手方向が、まな板を持つ人の体の正面から左右どちらの方向にも傾かないようにまな板1を持つことが自然である。このようにしてまな板1を持つと、図5に示すように、まな板1の前端縁2は、その右側に行くに従って手前方向に後退する。そのため、第二のヒンジ7の前端18を鍋の開口を超えて鍋の内部に届かせることができるのである。まな板1の前端縁2の右側が後退している分だけ、その前端縁2が鍋の開口の縁に当たるまで第二のヒンジ7を進めることができるからである。これにより、まな板1の、第二のヒンジ7の前端18付近の部分が鍋の内部に届いているので、食材を鍋に確実に投入することができる。従来のヒンジを有するまな板は、食材の投入時に、まな板の前端縁が鍋の開口と平行であるから、ヒンジを鍋の内部に届かせる前に前端縁が鍋の開口の縁に当たってしまい、ヒンジを鍋の内部に届かせることができず、食材が鍋の開口の外に落下させてしまうのである。   Next, the usage method when the opening of the pan to be introduced is narrow will be described with reference to FIG. In the conventional cutting board having a hinge, when the opening of the pan is narrow, the ingredients to be thrown out of the opening are not put into the pan. Therefore, in this embodiment, when the ingredients have been cut, first, the movable plate portions 9 and 10 are raised. Next, the cutting board 1 is moved slightly to the right so that the front end 18 of the second hinge 7 on the left side is located near the center of the opening of the pan to which the food is to be poured. Next, the cutting board 1 is tilted so that the second hinge 7 on the left side is lower than the first hinge 6 on the right side. Thereby, a foodstuff approaches the 2nd hinge 7 side. If you do not come close, use a knife or hand. Next, the cutting board 1 is tilted so that the front edge 2 of the cutting board 1 is lower than the rear edge 3. In this case, the cutting board 1 is brought close to the pan until the front end 18 of the second hinge 7 exceeds the opening of the pan. Then, the ingredients are put into the pan with the foods slightly left. In this case as well, it is natural to have the cutting board 1 so that the longitudinal direction of the central board portion does not tilt in the left or right direction from the front of the body of the person holding the cutting board. When the cutting board 1 is held in this way, as shown in FIG. 5, the front edge 2 of the cutting board 1 retreats toward the front as it goes to the right side. Therefore, the front end 18 of the second hinge 7 can reach the inside of the pan beyond the opening of the pan. This is because the second hinge 7 can be advanced by the amount by which the right side of the front edge 2 of the cutting board 1 is retracted until the front edge 2 hits the edge of the pan opening. Thereby, since the part of the cutting board 1 near the front end 18 of the second hinge 7 has reached the inside of the pan, the ingredients can be reliably put into the pan. A cutting board having a conventional hinge is such that the front edge of the cutting board is parallel to the opening of the pan when the ingredients are added, so the front edge hits the edge of the opening of the pan before the hinge reaches the inside of the pan. It cannot reach the inside of the pan, and the ingredients fall outside the pan opening.

他の方法として、ハンドル26を持って食材を投入する場合を説明する。例えば、刻んだ食材の量が比較的少量で、食材を鍋に投入するときに可動板部9,10を立てる必要がないときは、鍋を体の正面に置き、体の正面中央でハンドル26を手で握ってまな板1を持つと、前述した場合と同様に、中央板部8の長手方向は体の正面から左右に傾くことがなく、まな板1を下方に傾斜させて食材を中央板部8の長手方向に滑動させることができる。これにより、食材は、中央板部8の上をその長手方向に滑動して鍋に投入される。   As another method, a case where the food is put in with the handle 26 will be described. For example, when the amount of chopped food is relatively small and it is not necessary to raise the movable plate portions 9 and 10 when the food is put into the pan, the pan is placed on the front of the body and the handle 26 is placed at the center of the front of the body. When holding the cutting board 1 with the hand, the longitudinal direction of the central plate portion 8 does not tilt left and right from the front of the body, as in the case described above, and the cutting board 1 is tilted downward so that the food is fed to the central plate portion. 8 can be slid in the longitudinal direction. Thereby, foodstuffs are slid on the center board part 8 in the longitudinal direction, and are thrown into a pan.

なお、本発明は前述した構成に基づいて種々の態様をとることが可能である。例えば、ヒンジは前述した2つのヒンジ6,7以外に必要に応じて他のヒンジを設けてもよいことは勿論である。ハンドル26や摘み部30,31を有しないまな板であっても差し支えない。まな板1のいずれかの表面に目盛を設けてもよい。また、中央板部8の前端縁2の近くに吊り下げ用の孔を設けてもよい。双方のヒンジ6,7は、後端縁3から前端縁2の間に延びるものに限定されるものでなく、ヒンジ6,7の一方の端が側縁4又は側縁5に存在してもよい。実施形態は、右利き用として形成されているが、ハンドル26を底面11側に曲げ、ヒンジ6,7のV溝12,13を上面14に形成し、浅溝25,34を底面11に設けることにより、左利き用として形成してもよい。また、ハンドル26を曲げずに平面状とし、V溝12,13と浅溝25,34の深さを同じくすることにより、右利きと左利きの左右両用としてもよい。   In addition, this invention can take a various aspect based on the structure mentioned above. For example, as a matter of course, in addition to the two hinges 6 and 7 described above, other hinges may be provided as necessary. A cutting board that does not have the handle 26 or the knobs 30 and 31 may be used. A scale may be provided on any surface of the cutting board 1. Further, a hanging hole may be provided near the front end edge 2 of the central plate portion 8. Both the hinges 6 and 7 are not limited to those extending from the rear end edge 3 to the front end edge 2, and one end of the hinges 6 and 7 may be present on the side edge 4 or the side edge 5. Good. Although the embodiment is formed for right-hand use, the handle 26 is bent toward the bottom surface 11, the V grooves 12 and 13 of the hinges 6 and 7 are formed on the top surface 14, and the shallow grooves 25 and 34 are provided on the bottom surface 11. Thus, it may be formed for left-handed use. Alternatively, the handle 26 may be planar without bending, and the right and left-handed left and right handed may be used by making the V-grooves 12 and 13 and the shallow grooves 25 and 34 have the same depth.

まな板上の刻んだ食材を直接鍋に投入する際に、食材の滑動がまな板の傷に阻止されにくく、食材を投入する容器の開口が比較的狭いものであっても、刻んだ食材を容器に確実に投入することができ得る、 When putting chopped ingredients on a cutting board directly into a pan, the sliding of the ingredients is not easily prevented by scratches on the chopping board, and even if the opening of the container into which the ingredients are put is relatively narrow, the chopped ingredients are put into the container. It can be reliably inserted,
