DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to scissors capable of separating and washing a pair of scissors, and more particularly to scissors for cooking.

[0002]

2. Description of the Related Art Scissors capable of separating a pair of scissors are easy to clean, and the effect thereof is remarkable particularly for cooking scissors which are easily soiled. For this purpose, cooking scissors that can be disassembled have conventionally been proposed. The scissors shown in Japanese Utility Model Publication No. 63-1975 relate to cooking scissors in which the body of the scissors can be disassembled.
The body of the spindle protruding from one scissor body and the head provided at its tip are formed flat with the same thickness, so the head is not circular, and the hole provided on the other scissor body is a keyhole As shown in the above, a circular shaft hole and a rectangular hole for inserting the head of the support shaft are connected to each other.

In this conventional product, when the two scissors are separated from each other, the flat head of the support shaft is fully inserted into the keyhole-shaped hole, and then the support shaft partially in the keyhole-shaped hole is inserted. Shift the scissors so that all the torso move into the circular shaft hole and inscribe. Thereafter, the scissors are rotated by rotating the scissors so that the intersection angle between the scissors is smaller than that at the time of the joining, so that the scissors can be used as scissors.

[0004]

The conventional product has the above-mentioned structure, and a rectangular hole is formed along with a round shaft hole in a hole provided in the other scissor body for inserting the head of the support shaft. Since it is formed, the shape of the spindle head passing through this hole is not circular, but is formed flat and has a square cross-sectional shape. Therefore, the head of the conventional spindle is not circular but flat and thin. However, since the scissors are a tool transmitted from ancient times and the head of the support shaft has always been circular, there is a concept that the head of the support shaft of the scissors must be circular in the head of the customer, Such a flat head shape is hard to adjust to, so that the number of units sold has not increased drastically.

[0005] Further, in the conventional product, the head of the spindle is formed flat and the cross section is formed in a square, and the hole provided in the other scissor body has the shape of the head for inserting the flat spindle head. The combined rectangular holes were partially present. In both cases of joining and separating the pair of scissors, it is necessary to insert a flat spindle head into a rectangular hole and insert the same. Aligning the spindle head with the rectangular hole meant that when trying to insert the spindle head, the work had to be performed with both scissors at a constant crossing angle. Since the above-mentioned rectangular hole of the conventional product extends so as to be substantially orthogonal to the length direction of the scissors body,
During the work, it was necessary to perform both scissors almost perpendicularly.
Also, like the above-mentioned scissors, the spindle head is flat and the cross section is square, and there is a square portion in the shaft hole provided in the other scissor body,
Cooking scissors, which must keep both scissors at a fixed angle to align the spindle head with the rectangular hole when joining both scissors, are not limited to the above-mentioned conventional products, and have been proposed up to now. All the detachable cooking scissors have the same configuration.

[0006] When the conventional scissors body is joined or separated, when the scissors bodies are made orthogonal to each other, it is necessary to keep the elbows of both arms wide and the upper arms separate from the body. As a result, the hand holding the scissors becomes unstable, and the scissors cannot be connected well. Also, in order to insert the spindle head into the hole when connecting both scissors, the spindle head must be aligned with the square hole from the state before the spindle head is inserted into the hole. The scissors must be inserted at a constant crossing angle. In other words, when connecting both scissors, it is necessary to keep the crossing angle of both scissors constant before inserting the support shaft into the hole, and this crossing angle does not match slightly or the hand moves to fix the crossing angle If not, the scissors may not be assembled smoothly.

Furthermore, since the conventional product has a flat square head, the two scissors are separated when the two scissors are opened at a right angle during use, which is the same angle as when they are joined. Since there is no means for preventing the scissors, both scissors may be separated naturally. The present invention eliminates the inconveniences of the conventional products described above and makes the head of the spindle easy to fit in a circular shape. When inserting the spindle head into the hole, it is free to make both scissors almost perpendicular to each other. It has been conceived as an object to provide scissors that can be inserted into a hole at an appropriate intersection angle and that are easy to use.

[0008]

SUMMARY OF THE INVENTION The present invention is directed to scissors in which a pair of scissors bodies 1 and 2 are pivotally attached to each other in a crossed manner by a support shaft 3 so that both scissors bodies 1 and 2 can be separated and disassembled. A support shaft 3 is fixedly attached to one of the scissors body 1, and the support shaft 3 is formed such that a circular head 5 protrudes in a flange shape from the tip of a body 4 protruding from the scissor body 1. And the other scissors 2
A circular insertion hole 6 having an inner diameter through which the head 5 can be inserted and a circular shaft hole 7 capable of rotatably inscribing the body 4 are partially overlapped to form a single gourd-shaped hole. The body 4 rotatably inscribed in the shaft hole 7 passes through the constricted portion 8 at the boundary between the insertion hole 6 of the gourd-shaped hole and the shaft hole 7 and is located between the insertion hole 6 and the shaft hole 7. It is characterized in that the body 4 is provided with a narrow portion so that the body can be moved back and forth.

[0009]

The present invention is constructed as described above, and a spindle 3 having a circular head 5 is attached to one scissor body 1 and a spindle head is attached to the other scissor body 2. A gourd-shaped hole is provided in which an insertion hole 6 sized to allow insertion of the shaft 5 and a shaft hole 7 that can inscribe the trunk 4 of the support shaft partially overlap. When the pair of scissors 1 and 2 are joined, first, the scissors 1 and 2 are crossed at a free intersection angle, and the head 5 of the support shaft is inserted into the insertion hole 6. When the both sides of the narrow part of the body 4 of the spindle hit the narrow part 8 of the gourd-shaped hole, the body 4 of the spindle passes through the narrow part 8 The scissors body 2 may be moved so as to move to the shaft hole 7. Therefore, the head 5 is inserted into the insertion hole 6 at the beginning of the scissor body assembly.
The head 5 can be inserted into the insertion hole 6 by setting the crossing angle of the scissors body 1 and 2 to an angle desired by the user, and the head 5 can be inserted easily and smoothly. Head 5
Can be inserted in a slightly smaller angle than the conventional product, and can be inserted even when both scissors 1 and 2 are almost closed. When inserting the head 5 with both scissors 1 and 2 almost closed, the two elbows of both hands holding the scissors can be attached to the body, so that the hand is stable and the head 5 can be easily inserted. Become.

In addition, the crossing angle of the scissors body when the head 5 is first inserted may be changed at the time of insertion.
The head 5 can be inserted smoothly even if the hands move a little. In the conventional product, the crossing angle between the pair of scissors body 1 and 2 must be opened to a substantially right angle at the beginning of the scissor body assembly, and the angle must be fixed, so that the assembly is not smooth and troublesome. The present invention obviates the need to fix the crossing angle of the scissors at a constant angle required at the beginning of the scissors assembly.

As described above, when the pair of scissors bodies 1 and 2 are combined, first, the scissors bodies 1 and 2 are crossed at an arbitrary crossing angle, and the head 5 of the support shaft is inserted into the insertion hole 6. And then scissors 1,
2 is rotated to widen the crossing angle, and when both sides of the narrow portion of the body 4 of the spindle hit the neck 8 of the gourd-shaped hole, the body 4 of the spindle passes through the neck 8 Then, the scissors body 2 may be moved so as to move to the shaft hole 7. However, this assembling method is somewhat troublesome, and the advantage of the present invention only is that when the scissors body 1 and 2 are rotated during assembly, the scissor body 2 provided with the gourd-shaped hole is moved in the direction of the shaft hole 7. When rotating while slightly pushing, when both sides of the narrow portion of the body 4 of the spindle hit the neck 8 of the gourd-shaped hole, the body 4 of the spindle naturally passes through the neck 8 as it is. As a result, the scissors body can be assembled very easily.

The spindle head 5 is provided so as to project in a circular flange shape. Therefore, when the body 4 of the support shaft moves to the shaft hole 7 to be inscribed and used as scissors, the back surface of the flange of the head 5 is entirely covered with the shaft hole 7 except for the constricted portion 8 of the gourd-shaped hole. In contact with the surface of the scissors around. Therefore, even if the crossing angle between the pair of scissors bodies 1 and 2 is widened accidentally and both sides of the narrow portion of the body 4 of the support shaft hit the constricted portion 8 of the gourd-shaped hole, the flange of the head 5 can be used. Since most of the parts come into contact with the surface of the scissors body 2 to perform a locking action, there is no possibility that the head 5 comes out of the gourd-shaped hole and the two scissors bodies 1 and 2 come off. In the conventional product, when both scissors are opened so as to intersect at a right angle, the head is formed flat and only one end of the head is locked, and the other end is Because it escapes from the hole,
Eventually, the entire head comes out of the hole, and both scissors are separated and come off. Therefore, the present invention in which both scissors do not come off unexpectedly can be used safely.

Further, since the spindle head 5 of the present invention has a circular shape, it has a head shape similar to that of traditional scissors which has been used for a long time, and can be used comfortably even by the elderly. In the conventional scissors for detachable cooking scissors, the head of the support shaft is formed flat, so that the elderly feel uncomfortable and uncomfortable, but the present invention can eliminate such uncomfortable feeling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. A support shaft 3 is fixedly attached to one scissor body 1. The support shaft 3 has a circular cross section.
The lower half is threaded.
The support shaft 3 is fixedly attached to the scissors body 1 by a nut 9.

The upper half of the support shaft 3 is a trunk 4, and the trunk 4
Are cut into flat portions 10, 10. Therefore, the distance between the two flat portions 10 is smaller than the diameter of the body portion 4. The support shaft 3 is attached to the scissor body 1 so that the flat portions 10 and 10 are substantially perpendicular to the length direction of the scissor body 1. Further, a circular head 5 is provided at the tip of the body 4 so as to protrude like a flange.

The other scissor body 2 is provided with a gourd-shaped hole in which two circular holes having different inner diameters partially overlap. The two circular holes are provided so as to be continuous in the length direction of the scissors body 2. The larger hole is an insertion hole 6 for inserting the head 5 of the spindle, and has a size that allows the head 5 to pass through.

The smaller hole is a shaft hole 7 sized so that the body 4 of the support shaft can be rotatably inscribed. When the scissors 1 and 2 are opened and closed during use of the scissors. Becomes the center of rotation.
The insertion hole 6 and the shaft hole 7 are provided such that a part thereof overlaps to form a single hole, and thus the shape of the hole is a gourd. In the gourd-shaped hole, a constricted portion 8 is formed at the boundary between the insertion hole 6 and the shaft hole 7, and the width of the constricted portion 8 is smaller than the inner diameter of any of the insertion hole 6 and the shaft hole 7. It is formed so as to be slightly larger than the distance between the two flat portions 10 provided on the body 4 of the shaft. Since the constricted portion where the insertion hole 6 and the shaft hole 7 are formed is sharply pointed, the constricted portion 8 is cut in an arc or a straight line.

As a result of the constriction 8 being formed in this way,
The torso 4 of the support shaft first inserted into the insertion hole 6 rotates the scissors body so that the flat portions 10 and 10 of the torso hit the constricted portion 8, so that the other scissor body 2 is elongated in this state. When pulled in the transverse direction, the body 4 moves through the neck 8 into the shaft hole 7. A simpler and unique method of the present invention for assembling the scissors body is, as described above, when the scissors bodies 1 and 2 are rotated during assembly, the scissors body 2 provided with the gourd-shaped hole is inserted into the shaft hole 7. When the two flat portions 10, 10 of the narrow portion of the body 4 of the spindle hit the constricted part 8 of the gourd-shaped hole, the body of the spindle is naturally turned as it is while slightly pushing in the direction of Since the member 4 moves to the shaft hole 7 through the constricted portion 8, the scissors body can be assembled very easily. Further, even if the body part 4 is in a state immediately after the movement, the head part 5 of the support shaft is almost completely locked to the surface of the scissors body 2 except for the constricted part 8, so that both scissors body 1 , 2 do not come off unexpectedly. The scissors can be used by opening and closing both scissors after moving the body 4 into the shaft hole 7.

When the pair of scissors bodies 1 and 2 are separated and removed, the scissors body 2 provided with a gourd-shaped hole is rotated when the scissors bodies 1 and 2 are rotated to an intersection angle at which they can be separated. It turns while pulling slightly in the direction of the insertion hole 6. As a result, when both flat portions 10 and 10 of the narrow portion of the trunk 4 of the spindle hit the neck 8 of the gourd-shaped hole, the trunk 4 of the spindle naturally passes through the neck 8 as it is. As a result, both scissors can be removed very easily.
