Description

  The present invention relates to a cutter blade having a broken line, in which even when a part of the blade is broken from the broken line, the part is not scattered.

  There are cases where paper, resin, light materials, and the like are cut during manufacturing at a factory, work at home, and construction at a construction site. Or the work which cuts off an excess member for surface finishing may be performed in a construction site. In such cutting and cutting operations, a cutter knife may be used.

  The cutter knife houses a cutter blade having a severable cutting edge in a gripping case. The user can expose part of the cutter blade by exposing the cutter blade by removing the cutter blade from the tip of the case.

  The user implements the cutting and cutting work by applying the cutting edge to the object to be cut and cut.

  Thus, when the user performs a cutting operation or the like using the cutting edge of the cutter blade taken out of the case, the cutting edge of the cutting edge may be deteriorated. This is because the cutting edge cannot fully exhibit its cutting ability due to deterioration of the cutting edge or wear of the cutting edge.

  Most of the cutter blade is used for cutting or the like at the tip. For this reason, the cutting edge whose sharpness deteriorates by use is often only the tip portion of the cutter blade. It is uneconomical and inefficient that the entire cutter blade must be replaced only by the sharpness of the cutting edge of the tip portion only.

  For this reason, current cutter blades for cutter knives are provided with a plurality of broken lines that can be cut off little by little as the cutting edge of the tip portion becomes worse. The plurality of broken lines are provided along the longitudinal direction of the cutter blade. In many cases, they are provided at a predetermined interval, and can be broken up little by little along the fold line from the tip of the cutter blade.

  In this way, by using a plurality of polygonal lines, gradually remove from the tip part of the cutter blade, which has poor sharpness, and use the tip part having a sharp edge one after another with one cutter blade. Can do.

  In addition, since there is a broken line, when the cutter blade is made larger and used, the cutter blade breaks from the broken line when a load is applied. When such a high load is applied, the cutter blade is not broken severely because the cutter blade is folded together. For this reason, even when it is necessary to work with a high load, the cutter blade is not irregularly and violently destroyed, so that the danger during the work can be reduced.

  A cutter blade for a cutter knife is provided with a plurality of broken lines for the purpose of such economy, efficiency, safety, and the like.

  Under such circumstances, a technique regarding a cutter blade has been proposed (see, for example, Patent Document 1).

JP, 2014-94163, A

  Patent Document 1 is a cutter blade of a folding blade type having a blade folding line, and a surface modification coating is applied to the entire blade base material, and the ratio of the depth of the blade folding line to the cutter blade thickness is The cutter blade which is 0.10 or more and 0.60 or less is disclosed.

  The technique of Patent Literature 1 aims to ensure that the cutter blade can be folded at the blade fold line by specifying the ratio of the depth of the blade fold line provided in the cutter blade. Further, by increasing the depth of the blade folding line, the flexibility of the entire cutter blade is enhanced, and the object is to reduce wear on the blade edge.

  However, the cutter blade of Patent Document 1 is scattered by the impact of breaking the broken blade portion when the cutter blade is folded at the blade folding line. The cutter blade of Patent Document 1 is coated on the surface, but this is only for the purpose of suppressing the wear of the cutting edge, and the broken blade portion cannot be prevented from being scattered as it is.

  For example, a cutter blade may break from a broken line during a manufacturing operation in a factory. The broken blade portion is scattered by an impact when it is broken. In this scattering, it is unpredictable where the blade part will fly. In a factory, it is important to ensure safety, and it is not preferable that a broken blade portion is scattered in an unpredictable place. In order to maintain the subsequent safety, it takes time and effort to find a broken blade that has been scattered.

  The same is true for home work, and it is dangerous for blades that are broken in unpredictable directions to fly. Injuries may occur when flying, or you may be injured by stepping on the scattered blades with your feet.

  Moreover, in a construction site, a cutter knife may be used in high-altitude work. When a cutter knife is used during work at high altitude, the blades are scattered from the broken line. In this case, there is a concern that a broken blade falls from a high place and damages passersby on the ground. Such a concern is not limited to the safety of the worker, but is also a problem for ensuring safety to the surroundings.

  As described above, the conventional cutter blade has a merit in that the broken line is provided, but it has a problem that the broken blade is scattered unpredictably.

  In view of this problem, an object of the present invention is to provide a cutter blade in which a broken blade does not scatter even when the blade is broken from a broken line.

In order to solve the above problems, a cutter blade of the present invention includes a flat blade body having a cutting edge,
A plurality of folding lines provided on the blade body;
An anti-scattering material provided on at least one of the front and back surfaces of the blade body,
The fold line allows a part of the blade body to be folded.

  The cutter blade of the present invention is provided with a scattering prevention material on at least one of the front and back surfaces of the cutter blade, so that even if a part of the cutter blade is broken from the broken line due to a load, the broken part is not scattered.

  The broken part remains attached to the anti-scattering material, so that the user can remove the broken part manually. As a result, the broken part is not lost and safety in the workplace can be easily secured.

  As a result, the cutter knife can be used safely, and the working efficiency using the cutter knife is improved.

  (Embodiment)

  Embodiments will be described.

(Overview)
FIG. 1 is a side view of a part of a cutter knife of the present invention. The cutter knife 1 includes a case 2 and a cutter blade 3. The cutter blade 1 is accommodated in the case 2 to constitute the cutter knife 1. The cutter blade 3 can be taken in and out of the case 2, and the user pulls out the cutter blade 3 from the case 2 and uses the cutter blade 3. When the use is finished, the cutter blade 3 is accommodated in the case 2 and the cutter knife 1 is used. Can be used.

  The cutter blade 3 includes a blade body 4 and a blade edge 5. The blade body 4 is the entire outer shape of the cutter blade 3, and a part thereof is a cutting edge 5 that can actually cut. The cutting edge 5 is a part of the blade body 4 and is a part applied to the cutting object when the cutting object is cut.

  The user pulls out the cutter blade 3 from the case 2 and then applies the cutting edge 5 to the object to be cut to perform a cutting operation or the like.

  The blade body 4 is provided with a plurality of folding lines 6. The plurality of folding lines 6 are along the longitudinal direction of the blade body 4. That is, a plurality of folding lines 6 are provided so that the extending direction of the blade body 4 is divided into a plurality of sections. By this fold line 6, the blade body 4 is divided into sections in order from the tip to the root.

  When a certain load or more is applied to the blade body 4, the fold line 6 can cut off a part of the blade body 4 corresponding to this section. This is because the fold line 6 is formed in the blade body 4 in a groove shape, and the groove-shaped portion is bent and separated by a load of a certain level or more.

  For example, the sharpness of the cutting edge 5 at the tip of the blade body 4 may be deteriorated. This is due to deterioration and wear due to use. In such a case, I would like to remove the tip portion that became dull. In such a case, the user applies a load that warps the tip of the blade body 4. With this load, a part of the blade body at the tip portion is cut off from the fold line 6.

  Alternatively, a high load may be applied to the blade body 4 during work. Also in this case, the tip of the blade body 4 is cut off from the fold line 6. In this way, a part of the blade body 4 is cut off from the fold line 6, so that the economy and safety of the cutter blade 3 can be ensured.

  FIG. 2 is a side view of a part of the cutter blade in the embodiment of the present invention. As shown in FIG. 2, the cutter blade 3 includes a blade main body 4, a blade edge 5 that is a part of the blade main body 4 and can be cut in contact with an object to be cut, and a plurality of folding lines 6. Such a cutter blade 3 is used for the cutter knife 1.

  Here, the cutter blade 3 in the embodiment includes a scattering prevention material 7 on at least one of the front surface and the back surface of the blade body 4. FIG. 3 is a schematic view of the cutter blade in the embodiment of the present invention as seen from above.

  In FIG. 3, the anti-scattering material 7 is provided on the surface (left side in FIG. 3) of the blade body 4 of the cutter blade 3. In other words, the anti-scattering material 7 is attached to the surface of the blade body 4.

  As described above, the blade body 4 is bent at the fold line 6 and separated. The blade body 4 is cut off and part of the tip end side of the blade body 4 is detached. At this time, the anti-scattering material 7 can leave a part of the blade body 4 cut off. By being able to remain attached, a part of the cut blade body 4 is not dropped or scattered by the scattering prevention material 7.

  Since a part of the cut blade body 4 remains attached to the scattering prevention material 7, the cut part is not scattered from the blade body 4 (from the cutter knife 1). As a result, a part of the blade body 4 cut off from the folding line 6 can be confirmed and removed by the user while being connected to the scattering prevention material 7.

  Thus, the cutter blade 3 of the present invention can prevent the blade body 4 that is broken from the fold line 6 from being scattered or dropped while taking advantage of the fold line 6. As a result of this prevention, safety and work efficiency can be improved.

(Usage instructions)
FIG. 4 is a schematic view of the cutter blade according to the embodiment of the present invention as seen from above. The state which looked at the cutter blade 3 from the front similarly to FIG. 3 is shown. That is, FIG. 4 shows how the cutter blade 3 is seen when the cutter knife 1 is viewed from above.

  The user uses the cutter knife 1 for various purposes such as manufacturing work, work work, and building work. When the cutting edge 5 is deteriorated or worn during this operation, the blade body 4 is deflected in either the left or right direction as shown in FIG. That is, the blade body 4 is deflected to the front side or the back side. By deflecting, a load can be applied to the blade body 4.

  This load is also applied to the fold line 6 of the blade body 4. By applying this load, the fold line 6 is bent and cut.

  The arrows in FIG. 4 indicate the direction in which the load is applied. A load is applied according to the direction of the arrow. When this load causes a fold at the fold line 6, a state as shown in FIG. 5 is obtained.

  FIG. 5 is a schematic view of the cutter blade partially broken from the fold line according to the embodiment of the present invention as viewed from above. When the load in FIG. 4 exceeds a predetermined value, a part of the blade body 4 is cut off from a certain fold line 6. By being cut out, a cut portion 8 cut out from the blade body 4 is generated. The cut portion 8 is a part of the blade body 4 before being cut off.

  An anti-scattering material 7 is attached to the surface of the blade body 4. It remains in the state which the cut part 8 adhered to this scattering prevention material 7. FIG. FIG. 5 shows a state where the cut portion 8 is attached to the scattering prevention material 7. Due to this attached state, the cut portion 8 is not scattered or dropped. As a result, even if a part of the blade body 4 is cut off at the fold line 6, a disadvantage to safety or the like is prevented.

  The user only has to manually separate and remove the cut portion 8 that remains attached. At this time, the anti-scattering material 7 is cut with scissors and the cut portion 8 is cut off and removed.

  Next, the detail of each part is demonstrated.

(Blade body)
The blade body 4 forms the outer shape of the cutter blade 3. The blade body 4 includes a cutting edge 5 for cutting. Further, a plurality of folding lines 6 are formed, and the blade body 4 is divided into a plurality of sections by the plurality of folding lines 6. With this fold line 6, the blade body 4 can be cut for each section.

(Fold line)
The fold line 6 is formed in the blade body 4. A fold line 6 is formed so as to divide the blade body 4 from the tip side to the root side into a plurality of sections. The fold line 6 has a groove shape and is bent by a load. The portion where the sharpness of the cutting edge 5 is deteriorated by this bending can be removed.

  Note that the intervals between the plurality of folding lines 6 may be determined according to various specifications.

(Spattering prevention material)
The scattering prevention material 7 is provided on at least one of the front surface and the back surface of the blade body 4. For this reason, it may be provided on both the front surface and the back surface.

  Alternatively, the anti-scattering material 7 may be provided only on either the front surface or the back surface. By being provided only on either the front surface or the back surface, the cut portion 8 is easily separated from the blade body 4 from the fold line 6. This is because the blade body 4 is warped toward the side where the scattering prevention material 7 is not provided and the cut portion 8 is cut off from the fold line 6.

  This is because, in addition to this cutting, the cut portion 8 cut toward the scattering preventing material 7 remains attached to the scattering preventing material 7.

  It is also preferable that the scattering prevention material 7 is formed of any one of a film member, a tape material, and a thin film material. This is because such a material has flexibility and can be easily mounted on the metal blade body 4. Moreover, even if a part of the blade body 4 is cut off, these materials can leave the cut portion 8 as it is. Furthermore, even when the blade body 4 is cut off from the fold line 6, it remains without being cut and the cut portion 8 does not have to be scattered.

  Or it is also suitable that the scattering prevention material 7 is formed with an application | coating member. It is because the mounting | wearing becomes easy by forming with an application | coating raw material. After the application material is applied to the blade body 4, the application material is in a mounted state. After being in this mounted state, it has flexibility, adhesion, etc., like a film material. Due to this characteristic, the cut portion 8 is not scattered.

  In this way, the anti-scattering material 7 can stay without scattering the cut portion 8 which is a part of the blade body 4 cut from the fold line 6 and cut off. As a result, even when it is necessary to cut off a part of the blade body 4 along the fold line 6, the remaining cut portion 8 of the blade edge 5 is not scattered or dropped.

  As described above, the cutter blade 3 according to the embodiment can ensure safety without causing the cut portion 8 cut along the fold line 6 to be scattered or dropped. The cutter knife 1 having the cutter blade 3 can realize a safe operation.

  As described above, the cutter blade described in the embodiment is an example for explaining the gist of the present invention, and includes modifications and alterations without departing from the gist of the present invention.
