Description

  The present invention relates to a gripping / cutting tool used for an operation of gripping an object or food (hereinafter referred to as a gripped material) or a task of cutting a gripped material.

Conventionally, a gripping tool for gripping a material to be gripped has a folded portion formed by bending a band plate material into a U shape, and an extended portion of an arm portion with both ends of the folded portion equally extended as a working portion. There are those in which teeth are formed to face each part. (For example, see Patent Document 1)
In this gripping tool, when the size of the gripping material to be gripped varies widely, the interval between the working parts facing each other is greatly widened according to the size of the large gripping material. When gripping a small material to be gripped, the arm part is pushed from both outsides to bring the opposing working parts closer, but when the pressing force is released, it must return to the original large interval. Therefore, it has been necessary to increase the length of the arm part from the folded part to the working part so that the folded part bent into the U shape does not deform beyond the elastic limit.
Further, in order to grip a heavy gripping material without dropping it, gripping the arm portion close to the U-shaped bent portion requires pressing the arm portion with a strong force from the outside, so that the hands and fingers become tired.
Therefore, it is necessary to grip the part near the work part of the arm part and work with a light pressing force. However, when working near the work part, the U-shaped bent part extends long behind the gripped hand. Some people have the disadvantage of getting in the way.
In addition, when the conventional gripping tool tries to press the front end of the working part against the material to be gripped and push it forward (in the direction from the arm part to the working part), it must be gripped strongly to increase the pressing force, but it grips strongly. Since the working parts that oppose each other come into contact with each other and cannot be gripped, there is the annoyance that the other hand must push from behind the U-shaped bent part when the necessary working part interval is determined, It was not used for difficult work.
In addition, if the entire length from the bent portion to the working portion is long, there is a drawback that it takes a place when storing.

Conventionally, the U-shaped bent portion of the gripping tool is separated into two bodies, and the separated end is formed so that it can be engaged with a support shaft, and the support shaft is supported. There is a gripping tool that is biased so as to expand a working portion by incorporating a coil spring or a leaf spring. (For example, see Patent Document 2)
However, since the posture of the gripped material may be shifted when the gripped material is gripped due to the shakiness of the shaft support part, there is a troublesome work that requires careful attention to the shift.
In addition, if the overall length is shortened, the inclination of the arm portion becomes large when gripping a large material to be gripped, so that there is a drawback that it slides down from the hand under its own weight when the working portion is directed downward.
Further, when the gripping tool is washed, if it is used repeatedly for a long period of time, a portion where the cleaning tool (such as a dishwashing sponge) does not reach the shaft support portion is contaminated and becomes unsanitary.

In addition, in the scissor removing tool that takes the scissors of the conventional scissors, the band plate material is bent into a U shape to form a folded portion,
There was a form in which both ends of the folded portion were equally extended to form an arm portion, a sharp blade portion was formed obliquely on the extended portion of the arm portion, and the blade edge portion was sharpened. (For example, see Non-Patent Document 1)
To cut off the core of the heel with this blade, insert the sharpened blade tips on opposite sides across the core of the heel between the heel and the heel, and push the arm from both sides to remove the blade. The core was cut to remove the wrinkles.
However, in the case where the heel is actually stuck, there is a drawback that it is troublesome and troublesome because the sharp blade edge portion is cut after being inserted while pushing the heel between the heel and the heel.
In addition, if the hook is actually stuck and the above work method is troublesome, the hook can be cut off by pressing the blades on both sides so as to straddle the core from above the hook. Since the tip of the cocoon that is out of the mold is cut off, the swarf at the tip of the cocoon remains attached to the strawberry fruit and must be washed away or picked one by one to remove the swarf. So there was a drawback of being troublesome.
Also, when the fruit is hard, the core is hard, but when the cocoon is cut off, the hard core will remain in the fruit, so after removing the cocoon, remove the sharp edge by inserting it around the core. It was cumbersome to have.

In addition, the conventional cooking utensil for taking tomatoes has a saw-shaped blade on the periphery of the round spoon-shaped scooping part, and the blade is cut around the circumference of the tomato bowl and cut once it makes a round. There was a technique to scoop up the rare site. (For example, see Patent Document 4)
However, when making a cut, you have to make a round on the circumference and turn the tomato and change it. In addition, when the circumference of the incision is large, the incision must be repeated many times, and even when it is desired to cut with a circumference smaller than the spoon-shaped arc, there is a disadvantage that it cuts out outside the desired circumference .
Also, in the case of a real hard tomato, you have to put power when cutting it, but you can not apply the cutting force with good balance to the tomato held in one hand, so there is a disadvantage that it involves the risk of injury to slip and cut your hand there were.

In addition, the conventional cooking utensils that take the bell pepper and core of the bell pepper form a saw blade-like cutting edge at the periphery of one end of the thin cylinder, align the center of the cylinder with the core of the bell pepper, and rotate and swing the bell pepper. There was a technique to cut out the candy by biting. (For example, see Patent Document 5)
However, the size of the circle to be cut in accordance with the size of the bell pepper and the size of the cocoon is determined, but there is a drawback in that the cocoon part must always be cut into a cylindrical shape of the same size.
In addition, when cleaning, the inside of the cylinder in which the cutting edge is formed must be cleaned while paying attention to injury.

Further, there is a conventional fish small bone remover in which a band plate material is bent into a U shape to form a folded portion, and a gripping portion that sandwiches the bone is formed at the tip of an arm portion that is equally extended at both ends of the folded portion (for example, , See Patent Document 3)
This small bone remover is used by a method in which a portion close to the working portion side of the arm portion is pushed with fingers from both outer sides, the small bone is grasped and pulled by the grasping portion, and the small bone is pulled out from the fish body.
However, when the work is started, fish oil attaches to the small bone remover and the gripped finger and slips, making it difficult to maintain the gripping posture.
Also, when pulling out the small bones visible in the body, if you press the gripping part to push the fish away slightly, the finger that grabbed the small bone extractor will slide, and if you apply force to the gripped finger so that it will not slip, the gripping part will close There was a drawback that it could not be gripped.
Further, when pulling while holding the small bone, there is a problem that the finger slides with fish oil and the small bone removing tool cannot be held and cannot be pulled out.

Moreover, the conventional weeding tool is comprised by the lever part which act | operates the clamping part provided on the opposite side to the clamping part of the main body part and the main body part which hold | maintains this clamping part, and the main body part. (See Patent Document 6)
The use of this weeding tool is to position the two fingers of the clamping part so as to straddle the grass, and then operate the lever to clamp the grass with the two fingers and lift the finger upward to extract the grass. It is a method.
However, when positioning the two fingers at the tip of the long main body so as to straddle the grass, it is not easy to set the aim, so it takes time for weeding. In addition, since the weight of the entire weeding tool is large, there is a drawback in that the hands and arms to be operated become tired during repeated operations.

In view of the above-mentioned conventional drawbacks, the present invention is a hand that can be used by an elderly person, a child, or a person who feels inconvenience in hand movements with a light force when performing an operation of gripping a material to be gripped or a task of separating a material to be gripped. It is an object of the present invention to provide a gripping / cutting tool that can easily maintain a state of being held, and can perform a reliable operation with a light force without slipping even when a material to be gripped is pushed or pulled.

In order to achieve the above-described object, a folded portion in which a band plate material is formed in a U-shape or a double folded portion in which the band plate material is folded twice, an arm portion extending from both ends of the band plate material of these folded portions, A gripping / cutting tool is constituted by a working part provided with gripping means or cutting means in the extension part, and a finger contact part having a concave shape formed inside on the side close to the working part of the arm part.

According to the present invention, the following effects can be obtained.

2. The folded portion or double folded portion in which the strip plate material is formed in a U-shape, the arm portion in which the both ends of the strip plate member of the folded portion are equally extended, and both sides of the width in one of the extended portions of the arm portion. A horizontal blade part with a blade on the side, a serrated concave bite blade having a trough at the center of the width at the tip of the horizontal blade part, and a horizontal blade part with a blade formed on both sides of the width in the other extension And a serrated convex biting blade having a crest at the center of the width at the tip of the horizontal blade portion, the working portion is formed by opposing the concave biting blade and the convex biting blade, and the arm portions on both outer sides Since the trough of the concave bite blade and the crest of the convex bite blade mesh with each other when the working parts are pushed close to each other, the opposing working parts constitute a working part by crossing each other at an acute angle. After adjusting the space between the working parts to the size you want to separate, It can be cut into a conical shape by rotating rocking crowded pricked gripping member.
Therefore,
(1) For example, in the work of removing the scissors of the scissors, the distance between the opposing work parts is set to a required width, the center is set to the center position of the scissors, the grip is pushed in from the top of the scissors, and then the work part is slightly lifted up Since it can rotate, the cocoon is twisted and can be easily separated from the fruit.
(2) When the work part is gripped while being pushed from above the heel, the thin core connected to the heel is sandwiched between the trough of the concave bite blade and the peak of the convex bite blade through the thin heel, further increasing the gripping force. When added, the crests of the convex bite blades mesh with the troughs of the concave bite blades, and the core connected to the scissors sandwiched between them is securely gripped. If pulled up in this state, it can be cut together with the scissors.
(3) For example, in the operation of removing potato buds, after setting the distance between the opposing working parts to a width that is slightly larger than the size of the bud to be separated, and then inserting the center into the center of the bud, and then inserting it to the assumed bud depth If the swaying is slightly rotated, the periphery of the bud can be cut into a conical shape with the horizontal blade portion, so that the shoot can be easily cut just by grasping it and pulling it up.
The effect is obtained.

In claim 2, since the gripping and cutting tool of the present invention is provided with a finger contact portion formed in a concave shape on the inner side of the arm portion close to the working portion, it is stable only by lightly supporting the finger contact portion with a finger. And hold it.
Therefore,
(1) When the working unit is pressed forward, even if the force with which the finger holding unit presses the finger pad is small, the front inclined surface of the finger pad is pressed, so that the finger can be pressed stably without slipping.
Further, when the material to be grasped is gripped and pulled, the inclined surface behind the finger rest is pushed, so that the finger can be pulled stably without slipping.
(2) Even if juice, oil, or the like adheres to the hand or gripping / cutting tool and becomes slippery, it can be stably held without slipping because the finger is placed in the recess of the finger pad.
(3) When pushing forward or pulling backward, it is possible to work without sliding just by applying a light force to the inclined surface of the finger rest, and it can be stably held by the finger rest even during work. It can be easily used by elderly people who are not used to it, children, and people who feel handicapped.

The present invention includes a double folded portion 1 in which the strip plate material shown in FIG. 3 is formed in a long inverted folded shape, arm portions 2 and 2 extending from both ends of the double folded portion 1, and an extension of the arm portions 2 and 2. The working parts 3 and 3 provided with gripping means or separating means in the part and the finger contact parts 4 and 4 curved inward on the working parts 3 and 3 side of the arm parts 2 and 2 constitute a main form of implementation. ing.
Embodiments of the present invention will be described below.

In the first embodiment of the present invention shown in FIG. 1, both ends of the band plate material of the double folded portion 1 in which the band plate material is formed in a long inverted folding shape are extended to be arm portions 2, 2, and arm portions 2, 2 Working parts 3 and 3 are provided in the extended part of the working part 3, and a gripping tool is formed by forming a plurality of chevron teeth facing each other on the peripheral edges of the working parts 3 and 3.

As shown in FIG. 2, the conventional gripping tool forms the bent portion 1a by bending the banded plate material into a U-shaped shape without inverting it twice, and extends both ends of the bent portion 1a to make the arm portions 2 and 2 long. The working parts 3 and 3 having teeth for gripping are provided on the extension parts of the arm parts 2 and 2.
As shown in FIG. 2, the working units 3 and 3 are widened to face each other so that a large material to be gripped can be gripped.
When the working portions 3 and 3 are brought into contact with each other by applying a pressing force from both outer sides of the arm portions 2 and 2, the bent portion 1a is deformed, but the arm portions 2 and 2 are lengthened to be bent portion 1a. Since the amount of deformation is kept within the elastic limit, the interval between the working parts 3 and 3 returns to the original interval when the pushing force is released.
That is, since it is necessary to increase the length of the arm portions 2 and 2 in order to deform the bent portion 1a inward within the elastic limit of the band plate material, the entire length is also increased.
On the other hand, if the overall length of the gripping tool of FIG. 2 is shortened, the bent portion is greatly deformed inward when the working portions 3 and 3 come into contact with each other, and the band plate material exceeds the elastic limit. Even if the operation is stopped and the pushing force is released, the interval between the working units 3 and 3 does not return to the original state.
Therefore, if the double folded portion 1 is formed in a long inverted folded shape as shown in FIG. 1- (a) using a band plate material having the same length as the conventional gripping tool of FIG. 2, the overall length is shortened. However, substantially the same elastic limit as that of the conventional gripping tool can be ensured, and a substantially equivalent spring effect can be provided.
Therefore, if the gripping and cutting tool of the form shown in FIG. 1 is used, the effect of being able to grip a wide range from a large gripping material to a small gripping material can be obtained even if the overall length is shortened.
Further, the conventional gripping tool shown in FIG. 2 has a large radius of curvature of the U-shaped folded portion, but in the present invention, since the radius of curvature of the double folded portion shown in FIG. 2 is twisted in the opposite directions as indicated by arrows in FIG. 1- (b), the deformation amount is smaller than the gripping tool that forms the U-shaped folded portion in FIG. Even if a twisting force is applied, it can be stably held.

Next, different embodiments of the present invention will be described.
In the description of the different embodiments of the present invention, the same components as those of the first embodiment of the present invention are denoted by the same reference numerals, and redundant description is omitted.

In the second embodiment of the present invention in FIG. 3, the main difference from the first embodiment of the present invention is that a portion close to the working portions 3, 3 formed at the tips of the arm portions 2, 2. The finger rests 4 and 4 are provided so as to be recessed inward. (In FIG. 3, the band plate material is curved in the width direction from the arm portions 2 and 2 to the tip of the working portion to increase the bending strength in the longitudinal direction)
Further, teeth or blades are formed on the peripheral edge and the tip of the working parts 3 and 3.
When the distance between the working parts 3 and 3 is increased, the arms 2 and 2 do not become substantially parallel, but are inclined so as to be widened as shown in the figure, but the thumb rests on the finger pad parts 4 and 4 formed in a concave shape. By holding the index finger lightly, the gripping and cutting tool can be stably held even when the working unit is faced downward.
Further, when the conventional gripping tool holds the arm portion lightly and presses the working portion against the gripped material, the hand slips and the pressing force cannot be exerted. In addition, since the opposing working unit abuts before gripping when held firmly, there is no one that can perform pressing or stab operation.
However, in the present invention, when the front inclined surfaces of the finger contact parts 4 and 4 are pushed forward, the work parts 3 and 3 can be pressed against the object to be grasped or inserted without slipping the held fingers.
Further, there is an advantage that a forward pressing force and a force for gripping the material to be gripped can be applied simultaneously, and the distribution of the force in two directions can be adjusted.
Furthermore, when the operation | work which presses with a big force or the operation | work to puncture is required, it can push strongly if the double folding | turning part 1 is applied to the palm bottom, holding the finger pad parts 4 and 4 lightly.
The double folded portion may be coated with a rubber material or a synthetic resin material so as to be able to contact the palm bottom flexibly.
In addition, if the bottoms of the finger rests 4 and 4 on both sides are pressed with a finger, various operations can be performed such that only the gripping force by the working units 3 and 3 can be used without pushing forward.
In FIG. 3, the band plate material is formed in the double folded portion 1, but may be formed in the U-shaped folded portion 1a if the interval between the opposing working portions can be narrowed.

Next, an example of a gripping and cutting tool for taking a small bone of fish will be described.
As shown in FIG. 4, the tip portions of the working portions 3 and 3 are formed so that the straight tooth portions 5 and 5 are in contact with each other in the same manner as the barb remover, and a small bone is grasped between the tooth portions 5 and 5. Can be pulled.
The way of working is to hold the finger rests 4 and 4 lightly with the fingers and make the gap between the opposing tooth parts 5 and 5 slightly larger than the thickness of the small bones while lightly pushing the front inclined surface of the finger rests 4 and 4 By pushing the body around the fish ossicles with the tooth portions 5 and 5, the ossicles that are submerged can be gripped. If the ossicles are pulled back while being gripped, it can be retracted by applying a pulling force to the rear inclined surfaces of the finger pad portions 4 and 4, so that the ossicles can be easily pulled out.
The finger rests 4 and 4 are also easy to slide with fish oil, but the finger rests 4 and 4 are recessed so that they can be pushed without slipping by applying force to the front and back inclined surfaces. An effect is obtained that the work and the drawing work can be performed stably and easily.
Further, as a countermeasure against slipping of the finger, a satin treatment may be further applied to the surface of the finger rests 4 and 4.
Further, even in a medical instrument having a gripping function such as tweezers, the same effect as described above can be obtained by forming a finger rest.

In the third embodiment of the present invention in FIG. 5, the main difference from the second embodiment of the present invention is that a blade is formed on each side edge of each of the working portions 3 and 3 to form a horizontal blade portion. 6 and 6, and the leading ends of the working portions 3 and 3 are convex edges, and blades are formed on the convex edges to form biting blades 7 and 7.
Therefore, if the biting blades 7 and 7 are applied to the material to be grasped to advance, the material to be grasped can be inserted, and if the advancement direction is rotated after being inserted, the side blades 6 and 6 are circumferentially rotated. Can be cut in the direction.

Next, an example of cutting and removing the tomato pods and the cores connected to them will be described.
In FIG. 6, the arms 2 and 2 of the gripping and cutting tool are pushed from both outsides, and the gap between the biting blades 7 and 7 is adjusted to the size (diameter) of the ridge 9 of the tomato 8 to be removed and the core connected thereto. Next, when the center of the gap between the biting blades 7 and 7 is aligned with the center of the tomato 8 and pressed against the tomato 8 to advance, the biting blades 7 and 7 bite while cutting the tomato 8. When further pushed in, the horizontal blades 6 and 6 also bite into the tomato 8 in a taper shape.
Rotation is not in one direction, but if it is reciprocally rotated in the direction of arrow A within the range of movement of the hand H that grasps the gripping and cutting tool, the entire circumference around the core of the tomato 8 bites into the blades 7, 7 and sideways. The blade parts 6 and 6 are used for cutting.
After that, when the finger rests 4 and 4 are pushed from the outside and are pulled with light gripping force applied to the working parts 3 and 3, it is possible to easily separate from the fruit of the tomato 8 by pulling out the carved 9 and the core connected thereto. I can do it.
Even if the tips of the convex edges of the biting blades 7 and 7 are arranged at substantially the center of the width of each of the horizontal blade portions 6 and 6 and the blades are formed in a saw blade shape on both sides thereof, the same effect as described above is obtained. Is obtained.
Further, the same operation and effect as described above can be obtained when the operation for cutting the pepper cocoons is performed in the same manner as the operation procedure for cutting the potato and the core of the tomato.
Both the tomato example and the bell pepper example can be freely changed in the size of the round shape of the cocoon and the core, so that the minimum necessary core size can be separated without waste.

In the fourth embodiment of the present invention in FIG. 7, the main difference from the third embodiment of the present invention is that the blades are formed on both side edges of the working portions 3 and 3 to form the horizontal blade portion. 6 and 6, and a saw blade-shaped concave biting blade 10 having a trough at the center of the width of the tip of one horizontal blade 6, 6 is formed, and the width of the tip of the other horizontal blade 6, 6 is formed. A saw blade-shaped convex biting blade 11 having a crest at the center of the center is formed.
When the arm portions 2, 2 or the finger contact portions 4, 4 are pushed from both outer sides and the working portions 3, 3 are brought into contact with each other, the working portions 3, 3 are in the valleys of the concave biting blade 10 and the peaks of the convex biting blade 11. Are configured to enter and mesh with each other to cross each other at an acute angle.
Accordingly, the concave biting blade 10 and the convex biting blade 11 can be easily inserted into the gripping material in the same manner as in the third embodiment of the present invention. Therefore, the same effect as that of the third embodiment of the present invention can be obtained.

Next, an example of cutting and removing the cores connected to the ridges of the ridges will be described.
In FIG. 7, the substantially inscribed circle diameter of the star-shaped ridge of the cocoon to be removed by pressing the finger pad portions 4, 4 of the gripping / cutting tool from both outer sides to remove the opposing gap between the dent and blade 11. After pressing the concave biting blade 10 and the convex biting blade 11 lightly against the heel in accordance with the size of the front and back, pressing the finger rests 4 and 4 while slightly biting into the fruit, the core connected to the heel and the heel Since the concave biting blade 10 and the convex biting blade 11 can be securely gripped, the core connected to the ridge and the ridge can be cut from the fruit by lifting the gripping and cutting tool.
If the fruit is fully ripe, the core that leads to the cocoon is soft, so it can be separated only by grasping and pulling it up.
Further, when the fruit is hard, the core is also hard, but if the gripping operation as described above is performed, the core is also gripped by the trough portion of the concave biting blade 10 and the peak portion of the convex biting blade 11, When the convex biting blade 11 is pressed against the concave biting blade 10, the core is pressed against the valley bottom of the concave biting blade 10 and is firmly gripped. .
With the gripping and cutting tool of the present invention, the troublesome operation of inserting a blade between the fruit and the scissors like a conventional scissor removing tool, whether the scissors are attached to the fruit or separated from the fruit. There is no need to do.
In addition, even when it is not necessary to remove the wick core, or when you want to remove the wick core, you can easily separate only the part you want to remove without worrying about the state of the heel. .

Moreover, the holding | gripping and cutting tool in the 4th Embodiment of this invention can be used also for the operation | work which removes weeds.
FIG. 8 is a diagram in which a weed stalk 12 is guided to the valley bottom of the concave biting blade 10 and is pushed and held by the convex biting blade 11.
Lightly stab the root of the concave biting blade 10 so that it becomes the position of the stem of the weed, and then push the finger rests 4 and 4 from both sides to bring the concave biting blade 10 and the convex biting blade 11 closer to each other. The stem 12 is guided to the valley bottom of the concave biting blade 10, and when the convex biting blade 11 is brought closer, the stem 12 is securely grasped by the valley bottom of the concave biting blade 10 and the peak portion of the convex biting blade 11 as shown in FIG. Therefore, if we raise it as it is, weeds will be pulled out from the soil together with the roots.
Since the concave biting blade 10 and the convex biting blade 11 are small in shape, they do not hold a large amount of soil at the root when they are engaged with each other, so that they are not dug up to the soil for weeding.
When pulling out the weeds, a lifting force can be applied to the rear inclined surfaces of the finger rests 4 and 4 so that the fingers can be pulled out without slipping, so that the hands are not tired.
When the roots are pulled out, the soil entangled with the roots is pulled up together, but when you do not want to pull up the soil, if you hold the stalk 12 and hold the stalk 12 and rotate the rocking tool, Weeds are cut at the stem, so the soil is not lifted.
Therefore, unlike a conventional weeding tool, the hand can be held lightly, and the grass desired to be picked can be aimed at the fingertip instantly, so that the hand does not get tired.
In addition, there is an advantage that weeding can be performed by pulling out the roots with soil, or by removing the upper leaves from the stems while leaving the roots or selecting each grass to be removed.
