Description

  In the present invention, for example, in the case of electric wire cutting work, for example, each time the tool is moved to a ruler, the length is measured and the cutting point is marked, and then the tool is gripped again. The present invention relates to a scaled tool that can easily and quickly perform efficient operations such as cutting an electric wire.

  Conventionally, when working to cut an electric wire in construction work such as electrical wiring, it is essential to determine the cutting position of the electric wire. Then, change to a different ruler, measure the cutting position of the wire, determine its position, and mark it. After that, holding the tool again, the mark was cut with the tool. In this way, in conventional wire cutting work, the tool does not have the function of a ruler, so each time, the tool is changed from the tool to the ruler and measured, and the tool is moved again to cut the wire. It was.

On the other hand, as a technique in which a tool and a ruler with a scale are integrated, for example, a technique described in Japanese Patent Application Laid-Open No. 2001-121884 (Patent Document 1) is known. Japanese Patent Application Laid-Open No. 2001-121884 has a configuration in which a slit is formed along a scale of a scale and a cutter portion is slidably attached to the slit. When cutting paper etc., you can cut the paper etc. by pressing this cutter part from above and sliding it along the slit while biting the cutter part into the paper etc. Yes.
JP 2001-121884 A

However, in the cutting operation of the electric wire with the above-mentioned conventional tool, since the tool itself does not have a ruler function, it must be changed from the tool to the ruler once, and then again from the ruler to the tool. Due to the time required, there was a problem that electrical work could not be completed within the restricted construction time.
In the technique described in Patent Document 1, when cutting paper or the like, it is convenient because length measurement and cutting can be performed simultaneously. However, such a configuration has a structure that is inconvenient for cutting a cable member such as an electric wire, and has a problem that it cannot contribute to shortening of electrical work.

  The present invention has been devised in view of the above problems, and by integrating a ruler with a scale on a tool such as a knife or pliers, and providing a protrusion on the tool to mark the cutting location With a scale that can easily and quickly measure and cut the length of a wire without letting the tool go by, eliminating the need to change from a tool to a ruler one by one when cutting the wire in electrical work, etc. The purpose is to provide a tool.

  In order to solve the above problems, the present invention takes the following measures. That is, the tool with a scale according to the present invention is a tool having a cutting part for cutting an electric wire, and the tool is measured with a ruler part in which a scale for measuring the length of the electric wire is formed on the tool, and the ruler part. And a protruding portion for marking the cut portion of the electric wire with a mark by an indentation. The tool itself has a structure in which a ruler provided with a scale and a protruding part that indents the cut portion and marks the mark are integrally provided. For this reason, the operator can mark the mark by measuring the cutting position of the electric wire while holding the tool and pressing the protrusion against the electric wire. Therefore, since this indentation part can be cut with a tool as a mark, the cutting operation of the electric wire or the like can be performed easily and quickly in a short time, and the work efficiency can be improved.

  The scaled tool may specifically be a knife. In this case, of course, it is possible to peel off the covered portion of the electric wire to be insulated with a synthetic resin material with a knife and to form a scale as a ruler portion on the blade portion and the gripping portion. Without changing to a ruler, it is possible to easily and easily cut the electric wire at the cutting portion of the knife by marking the cut portion of the electric wire while holding the knife.

  As another tool with a scale, a pliers may be used instead of a knife. In this case, a measure part with a scale may be provided on the grip part of the pliers formed in a substantially straight line. Is possible. For this reason, the location where the electric wire is cut is measured with a ruler provided on the gripping portion of the pliers and the cut portion is marked and defined by the projection, and the cut portion is cut or the covering portion of the electric wire is peeled off. You will be able to.

  Further, the protrusion is preferably near the end of the knife gripping part or pliers gripping part opposite to the position where the cutting part exists, and the position substantially coincides with the position corresponding to the origin of the ruler part. It is good to provide in the position to do. Thereby, since the position of the protrusion becomes the origin of the ruler, the scale increases from the origin toward the cutting portion of the knife or pliers. For this reason, an indentation is made on the electric wire by a simple operation in which the cut portion of the electric wire only presses the protruding portion against the electric wire, and the mark of the cut portion is marked. As a result, the electric wire can be cut in a short time.

  Further, as a preferred mode of the ruler part, it is possible to form a concave groove capable of applying an electric wire to the grip part of the pliers and to provide a protrusion at an appropriate position along the scale of the concave groove. is there. According to this, the cutting position where an electric wire cuts can be made highly accurate. Of the pair of gripping portions, the groove width and depth of the groove groove formed on the gripping portion on one side and the groove groove provided on the gripping portion on the other side are formed to be different from each other. It becomes possible to use properly according to the size of the thickness.

  According to the present invention, since the tool itself has a structure in which a scale part provided with a scale and a protrusion part that indents the cut portion and marks the mark are provided integrally, the operator holds the tool. The cut portion of the electric wire is measured, and the mark that becomes the cut portion is marked by pressing the protrusion on the electric wire at the corresponding measurement position. As a result, the indentation site can be used as a mark to cut the electric wire at the cutting portion by the cutting portion of the tool, and as a result, the cutting operation of the electric wire, etc., or the stripping operation of the covering portion of the electric wire can be easily performed in a short time. It can be done quickly and has the effect of significantly improving work efficiency.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. As a scaled tool according to the first embodiment, a case where it is applied to a knife for electrical work will be described as an example. As shown in FIGS. 1 to 3, the knife 1 of the first embodiment has a narrow U-shaped cross section, and a gripping part formed of a metal material such as iron or stainless steel by sheet metal processing, for example. 2 and a blade portion 4 supported by the grip portion 2 so as to be rotatable by a pin shaft 3. A blade portion 5 as a cutting portion is formed at the tip portion of the blade portion 4 along an inclined edge portion. When the knife 1 is not used, the blade part 4 is stored in the space S in the grip part 2 as shown by the two-dot chain line in FIG. By taking out, it rotates as shown by the solid line. And the stopper member 6 (metal material) which consists of a small piece is welded and attached to the upper part (near the top surface 2a) of the end surface of the grip part 2 near the pin shaft 3 (see FIG. 2C). . Thereby, when the blade part 4 is rotated and pulled out by approximately 180 degrees, the end surface 7 on the blade part 4 side is engaged with the stopper member 6, and as shown in FIG. 2a and the heel part 8 of the blade part 4 continuously form a substantially straight line, and form a straight ruler.

  Further, a ruler 9 is provided at a portion along the vicinity of the top surface 2 a of the grip portion 2 and a portion along the vicinity of the collar portion 8 of the blade portion 4. That is, the ruler part 9 is formed by marking the grab part 2 and the blade part 4 with a scale and numbers. These scales and numerical values are preferably stamped on both surfaces of the grip portion 2 and the blade portion 4, but it is needless to say that they may be provided only on one side. This numerical scale has the origin in the vicinity of the end surface of the grip portion 2 opposite to the pin shaft 3, and the number increases in the direction toward the blade portion 5. Thereby, in this 1st embodiment, in the state which developed blade part 4 in the shape of a straight line, ruled part 9 whose maximum measurement length is 25 blade parts is formed.

  Further, as shown in FIG. 2A, a protrusion 10 is integrally provided on the top surface 2a of the gripping part corresponding to the origin of the ruler 9 in the gripping part 2, and the tip of the protrusion 10 is exactly the origin “ It corresponds to the “0” position. For this reason, the protrusion 10 can be pressed against the covering member of the electric wire to make an impression on the surface of the covering member.

  A use aspect of the knife 1 which concerns on 1st embodiment is demonstrated. That is, when the electric wire is cut using the knife 1 and the covering member of the electric wire is peeled off, the blade portion 4 is rotated around the pin shaft 3 from the grip portion 2 as shown in FIG. It can be implemented in the unpacked state.

Further, when the cutting portion of the electric wire is measured with the ruler 9 and then is to be cut, as shown in FIG. 3, the gripping knife 1 is brought close to the electric wire 11 and the ruler 9 is moved along the electric wire 11. . Next, for example, when cutting at a site 20 cm from the end of the electric wire 11, the scale “20” is aligned with the end of the electric wire 11. At this time, the tip of the protrusion 10 is pressed from above the covering member of the electric wire 11. Thereby, the impression by the projection part 10, ie, the mark E used as a cutting location, is marked on the surface of the covering member (see FIG. 3). The electric wire 11 can be cut at 20 cm from the tip of the electric wire by applying the blade portion 5 to the marked mark.
When the knife is not used, the knife 1 can be safely carried by storing the blade part 4 in the space S of the grip part 2 as shown by a two-dot chain line in FIG.

  As described above, according to the first embodiment, the ruler portion 9 having a scale and the projection portion 10 that indents the cut portion and marks the mark are integrated with the knife 1, Not only can the covering member of the cutting part electric wire 11 be peeled off, but another conventional ruler is applied to the electric wire 11 to measure the length, put a mark on the cutting part, and change to a knife again. The troublesome work of cutting the cutting part is omitted, the mark E is marked on the cutting portion of the electric wire 11 while holding the knife 1, and the cutting work can be performed easily and quickly in a short time. As a result, the cutting work The efficiency of can be greatly improved.

  In the first embodiment, the case of the folding knife 1 has been described. However, instead of this, the invention can also be applied to a sliding knife 20 as in the modification shown in FIG. That is, the knife 20 is, for example, a gripping part 21 formed of a metal material so as to have a flat space by sheet metal processing, and the inside of the gripping part 21 slides to a storage position via a slide mechanism and protrudes to the outside. The blade portion 22 is formed so as to enter and exit. The slide mechanism includes elongated slot holes 23 and 24 formed at opposite positions on both side surfaces of the gripping part 21, a slider 25 that is slid and guided in the slot hole 24 on one side surface, A screw shaft 26 that is integrally attached and penetrates the blade portion 22 and protrudes into the long hole groove 23 on the other side surface, and is screwed into the screw shaft 26 and can be engaged with the outer surface of the long hole groove 23 on the other side surface. And a screw 27 for fastening. By tightening the screw 27, the blade portion 22 is positioned and fixed to the grip portion 21 at that position, and conversely, the blade portion 22 can be freely slid by loosening the screw 27. It can be positioned and fixed by adjusting the protruding length.

  In addition, as shown in FIG. 4, the gripping portion 21 and the blade portion 22 are formed with a ruler portion 28 in which a scale is engraved, and a protrusion is formed on the top of the gripper portion 21 corresponding to the origin of the ruler portion 28. A portion 29 is provided. As shown in FIG. 4C, the ruler 28 is configured so that, for example, a 15 cm scale ruler is formed across the gripper 21 and the blade 22a at the tip of the blade 22 as shown in FIG. 4C. It has become.

  Therefore, also in this modified example, as in the case of the first embodiment, a short time can be obtained due to the indentation (mark) that becomes a mark of the cut portion that is formed when the protruding portion 29 is pressed against the electric wire 11 (see FIG. 3). Thus, the electric wire can be cut with the blade portion 22a of the knife 20 easily and easily.

  Further, instead of the knife 1 of the first embodiment, the present invention can also be applied to a knife 30 that is formed in a shape that forms a straight ruler shape as another modification shown in FIG. That is, the knife 30 is formed with a ruler 31, a protrusion 32, and a blade 33, for example, with a scale of 25 cm along the collar. In such another modification, the ruler 31 is provided integrally with the knife 30 itself, so that the electric wire can be cut in a short time in substantially the same manner as in the first embodiment and the modification. .

  Next, a second embodiment of the present invention will be described. That is, in the first embodiment, each modification has been described with respect to the case where it is applied to the knives 1, 20, and 30 as scaled tools. Instead, in the second embodiment, as shown in FIG. This is applied to the pliers 40. The pliers 40 have a cutting part 41 for cutting an electric wire, and a pair of gripping parts 42 and 43 are coupled via a pin shaft 44 so as to be rotatable. The gripping portions 42 and 43 have a substantially linear shape, and are provided with 15 cm rulers 45 and 46 in which scales are engraved. In addition, protrusions 47 and 48 are formed integrally with the gripping portions 42 and 43 at the positions corresponding to the origins of the rulers 45 and 46. These rulers 45 and 46 are provided on one side or both sides of each gripping part 42 and 43. According to the pliers 40 according to the second embodiment, since the ruler portions 45 and 46 and the protruding portions 47 and 48 are integrally provided on the pliers 40 itself, the pliers 40 are used to cut into electric wires. The length can be measured, and then the protrusions 47 and 48 can be pressed against the electric wire to mark the portion that becomes the cut portion of the electric wire. In this way, the length of the electric wire to be cut can be measured using pliers, the cut portion can be marked, and the cut portion 41 can cut the electric wire at the cut portion. For this reason, according to the second embodiment, the electric wires can be cut efficiently in a short time, and the efficiency of the electrical work can be improved, almost as in the first embodiment and each of the modifications.

As a modification of the second embodiment, as shown in FIG. 7, a ruler provided in the gripping portions 42 and 43 is formed in, for example, large and small concave grooves 49 and 50 that are recessed in a kamaboko shape, For example, the concave grooves 49 and 50 may be provided with concave projections 49a and 50a instead of the projections 47 and 48 every 1 cm. In such a modification, by inserting the electric wire into the concave grooves 49 and 50 and pressing the electric wire against the concave grooves 49 and 50 at a size to be a cut portion, an indentation that marks the electric wire by the protrusions 49a and 50a is formed. It has come to be attached. For this reason, according to this modification, the electric wire can be cut with a more accurate dimension in substantially the same manner as in the second embodiment.
In the above modification, the grooved grooves 49 and 50 are of large and small shapes having different groove widths and depths so that they can be properly used and measured even if the outer diameters of the wires are different. Of course, it is possible to provide the same type.

As mentioned above, although each embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. It is included in the scope of the present invention.
For example, instead of the pliers 40 as a scaled tool, it can be applied to tools such as nippers and pliers, and also to a wire stripper having a function of not only cutting an electric wire but also peeling only a covering member. Needless to say, it can be applied.
Further, in the above, the scales 9, 28, 31, 45, 46 are formed by engraving, but instead, the scale part is formed by attaching a tape created by printing these scales. It is also possible to do. In this case, a transparent thin plate made of, for example, a synthetic resin material is appropriately covered in order to prevent the scale from disappearing with the oil of the hand of the operator. Thereby, the visibility with respect to a scale can be maintained and it becomes convenient.
In addition, although the projections 10, 29, 32, 47, and 48 in each of the above embodiments and modifications are integrally fixed to the grips 2, 21, 34, 42, and 43, Instead of this, although not shown, a configuration may be adopted in which the protrusion is attached so as to slide along the scale. In this way, it is possible to slide the protrusion from the origin to a position where it becomes a desired disconnection point, and then press the protrusion against the electric wire to make an indentation. Of course, when not used as a ruler, it is possible to keep the grip of the gripping part in the normal wire cutting operation without any trouble by moving the slide projection part to the origin side.
