  When wallpaper is to be cut into multiple layers, hold the ruler in one hand, hold the cutter knife in the other hand, position the ruler at the cutting position and press it, and align the blade of the cutter knife along the ruler. In the vicinity of the ceiling, cutting is performed with a hand stretched on the stepladder, and the ruler is shifted downward while maintaining the linearity of cutting according to the cutting from above.

  And when the floor, for example, near the skirting board, the cutter knife is not moved from top to bottom, but it is turned 180 degrees and the cutter knife is moved from bottom to top, that is, upward from the edge of the skirting board. Then, it is cut from the bottom to the top so as to match the end of the cutting from the upper direction, and the overlap cutting is performed.

  In the cutter knife, the main body portion that houses the cutter blade 10a is called a body or a holder 10c. The front end side of the holder 10c is made of metal, and the rear end side that is held by hand is made of resin parts. Normally, the tip of the holder 10c is usually shaped to project at an acute angle.

  In many cases, the thickness of the cutting ruler in wallpaper construction is set to about 5 to 10 mm, and each wall paper contractor selects and uses a ruler having any desired thickness.

  When holding the cutter knife in the right hand and holding the cutting ruler in the left hand, the cutter blade 10a is placed along the side of the ruler so as to press the cutter blade 10a at the tip of the holder. However, in the case of moving the cutter knife close to the floor and moving upward from the skirting board as described above, the surface of the cutter blade 10a facing the tip of the holder will be along the side of the ruler. The cutter blade 10a must be pressed against the upper and lower part of the opened portion so that the cutter blade 10a can be seen. In addition, since there is a slight gap in the holder 10c, the cutter blade 10a is more warped if the rattling of the cutter blade 10a is greater than when pressing at the tip of the holder. Skill was required for the movement to move.

  In particular, since the work is performed near the floor, the operator must be in a squatting position, and it is necessary to pay attention to the force, and the cutter knife 10a is pressed against the ruler with a constant force to move the cutter knife with good linearity. However, the pressing force fluctuates, and as a result, the wallpaper may be rippled.

  Furthermore, the cutting line that is cut while shifting the ruler downward from the ceiling, the line that is cut from the bottom to the top, and the line that cuts from the bottom to the top may be shifted without matching. It was. Therefore, there has been a demand to stabilize the linear cutting accuracy of the wallpaper.

  In addition, the cutting object such as wallpaper pressed from above with a ruler is stably cut because it does not move at the time of cutting because it is pressed by the ruler, but the cutting object on the side not pressed by the ruler (for example, When wallpaper is cut slightly, the knife is moved and the glue is applied softly when it is moved. It was also desired to solve the problem that it would be torn and it would take time to correct the break so that it would not be noticeable.

  In the technical content disclosed in Patent Document 1, although the problem of injuring a finger can be solved, the above problem in wallpaper construction cannot be solved. And, the problem of scraping the ruler with the cutter blade remains, and the wall paper construction cannot solve the problem.

  In the technical content disclosed in Patent Document 2, although the problem of scraping the ruler can be solved and the stability of the hand can be achieved, the moving direction of the cutter knife has been limited to one direction. That is, if the step is moved downward from the ceiling, it cannot be used for reversing 180 degrees near the floor and moving from the bottom to the top, and the cutter knife itself is also costly due to the shape having the step. It is even configured to take. Moreover, the cutter blade is configured to be provided near the tip of the step, and is configured to cut in a state where the blade tip is not visible. In wallpaper construction, it is necessary to cut the blade edge while confirming how much the cutting edge is biting into it, and to construct it so as not to damage the background of the wallpaper.

  In the technical content disclosed in Patent Document 3, the blade of the cutter knife inserted from the knife insertion hole is supported by the wall of the knife insertion hole of the cutting aid and the side surface of the cut base body, and is stable without shaking. Although it is stated that the cutting aid is also stable because the cutting aid is also fitted on the convex rail of the cut base body, it is used on the cut base body placed on a table etc. In the case where the ruler is fixed in the vertical direction as in the case of wallpaper construction, the cutting assisting tool slides down due to its own weight, so that the knife cannot be inserted into the knife insertion hole. Moreover, it is the structure which cannot see the blade edge | tip of a cutter blade similarly to patent document 2, and cannot cut down a wallpaper so that it may not cut | disconnect the groundwork of a wallpaper, looking at a blade edge | tip. The ruler of Patent Document 3 is also dedicated, and it is based on the premise that the ruler that has been used and used up to now must be replaced with that of Patent Document 3, so that it can solve problems in wallpaper construction. It wasn't.

  In the technical content disclosed in Patent Document 4, it is intended to prevent the base from being damaged. However, if an underlaying member is placed on the back side of the wallpaper to which glue has been applied, the glue applied to the wallpaper is scraped off. In addition, even if the underlay member is made thin, at the position where the wallpaper is cut because the underlay member is inserted, the wallpaper is lifted by the underlay member. When trying to lift the pasted wallpaper with an underlaying member, there was a possibility that glue was applied to break the wet wallpaper. Furthermore, since the wallpaper is lifted from the wall with the underlaying member, the wallpaper that was originally cut in a state that fits perfectly without the underlaying member, each end was slightly longer as it was lifted with the underlaying member It will end up in multiple cuts. For this reason, it is inevitable that it will take time to finish the end of the wallpaper. As described above, in Patent Documents 1 to 4, the problem cannot be solved, and improvement is desired.

In the technical content disclosed in Patent Document 5, the cutter blade is protruded from the cutting tool, and means that serves as a presser when cutting the cutting object on both sides of cutting the cutting object. If you try to cut wallpaper that contains moisture at the tip of the cutter blade, you will not be able to cut it, and the tip of the cutter blade will break to drag the wallpaper that is easy to break with moisture There was a possibility that it might happen, and improvement was desired.

  In order to solve the above-mentioned problems, the present invention is capable of holding a cutting tool for storing a cutter blade, and a slider that is connected to the holding means to adjust the protrusion amount of the cutter blade of the cutting blade. A holding portion that protrudes in a direction parallel to the surface that the cutting object forms than the cutting edge of the cutter blade that protrudes from the holding means, and that holds the cutting object on both sides of the cutting edge of the cutter blade; The cutting blade held on the surface has two guide surfaces parallel to the cutter blade, and the cutter blade is disposed at a position where the distance from the two guide surfaces is equal.

  Further, the present invention provides a holding means for holding a cutting blade that houses a cutter blade, a groove portion that is connected to the holding means and that allows the movement of a slider that adjusts the protruding amount of the cutter blade of the cutting blade, Pressing means for pressing the cutting object on both sides of the cutter blade, projecting in a direction parallel to the surface of the cutting object having the same dimension as the cutting edge of the cutter blade protruding from the holding means, The held cutting blade has two guide surfaces parallel to the cutter blade, and the cutter blade is arranged at a position where the distance from the two guide surfaces is equal.

  Further, the present invention provides a holding means for holding a cutting blade that houses a cutter blade, a groove portion that is connected to the holding means and that allows the movement of a slider that adjusts the protruding amount of the cutter blade of the cutting blade, A pressing means that protrudes in a direction parallel to the surface of the cutting object in a state shorter than 1 mm with respect to the protruding dimension of the cutting edge of the cutter blade protruded from the holding means, and holds the cutting object on both sides of the cutting edge of the cutter blade; The cutting blade held by the holding portion has two guide surfaces that are parallel to the cutter blade, and the cutter blade is disposed at a position where the distance from the two guide surfaces is equal. .

More specifically, the means for holding the cutting blade for storing the cutter blade-more specifically, a slot that can be disposed in the cutting tool main body (holder) tilted in the cutting tool main body (holder), It is possible to comprise fixing means for locking and fixing the position of the cutting blade disposed in the slot.

  Since the cutter blades are arranged at the same distance from the two guide surfaces, when cutting downward from the ceiling or cutting upward from the floor, the cutting line will not shift and the cutting tool Easily invert and check how much the cutter blade is in the cut object while looking at the protruding cutter blade, while checking the bottom of the cutting tool and the pressing means protruding from the cutter blade, or the cutting edge of the cutter blade Stable cutting work while holding both sides near the cutting position of the cutter blade by pressing means protruding with the same dimension as the protruding dimension or pressing means protruding less than 1mm shorter than the protruding dimension of the blade edge of the cutter blade Can be done.

The amount of protrusion of the cutting blade of the cutting blade can be adjusted by adjusting the fixing position of the cutting blade with respect to the cutting tool by means of the cutting blade holding means provided in the cutting tool. It is possible to prevent cutting.

It is a figure explaining the cutting tool of the state which attached the cutter knife. It is a figure explaining the pressing means of the cutting tool. It is a top view of the tool for cutting. It is a figure explaining another embodiment of the pressing means of a cutting tool.

  Embodiments of the present invention will be described with reference to the drawings. The cutting tool 1 of the present invention is a guide for attaching a cutter knife 10 that is a cutting blade, and FIG. 1 shows a state in which the cutter knife 10 is attached.

As shown in FIG. 1, the cutting tool 1 is provided with a groove capable of tilting and fixing the cutter knife 10, and the first groove 1 c is substantially the same as the holder 10 c of the cutter knife 10. Slots of dimensions are formed. And the 2nd groove | channel 1d is provided as an open groove | channel which can slide the slider 10b of the cutter knife 10 freely in the state open | released in the guide surface 1a side.
The cutter knife 10 is inserted into the first groove 1c and the second groove 1d, and the cutter knife 10 is pressed toward the guide surface 1a by the fixing screw 3 provided on the guide surface 1b side. The position is fixed by pressing the cutter knife 10 against the step between the first groove 1c and the second groove 1d.

  1 and 2, the pressing member 2 is fixed to the bottom surface side of the cutting tool 1, and the pressing portion 2a protrudes from the cutter blade 10a of the cutter knife 10 so that the pressing portion 2a is the cutter blade 10a. The cutter blade 10a is configured to cut in a state where the object to be cut is pressed on both sides.

  FIG. 2 illustrates a state in which the main body of the cutting tool 1 and the pressing member 2 are separated. The pressing member 2 is attached to the bottom surface of the cutting tool 1 by, for example, bonding or fixing with a double-sided tape or the like.

  As shown in FIG. 2, the pressing member 2 covers the bottom surface of the cutting tool 1 and protrudes more than the cutter blade 10a on the cutter blade 10a side, and is circular on the side where the main body of the cutter knife 10 protrudes. It is set as the arc-shaped part 2b, and it is set as the structure which is easy to slide in the state contact | abutted to the cutting object. Therefore, the pressing member 2 has an arcuate bend in a side view but is substantially L-shaped, and is firmly fixed to the main body of the cutting tool 1 by adhesion or the like.

  The state in which the pressing portion 2a protrudes from the cutter blade 10a of the cutter knife 10 is a position where the cutting edge of the cutter blade 10a contacts the object to be cut, that is, the straight line of the blade of the cutter blade 10a and the bottom surface of the cutting tool 1 The position where the crossing points is located closer to the main body side of the cutting tool 1 than the tip of the pressing portion 2a. That is, the above-mentioned intersecting points are located between the pressing portions 2a located on both sides of the cutter blade 10a.

  The main body of the cutting tool 1 is preferably made of resin, and the pressing member 2 is preferably made of metal such as stainless steel so that the durability is improved. It is also desirable to use a transparent resin for the main body of the cutting tool 1.

  The surfaces to which the ruler is applied are the guide surface 1a and the guide surface 1b. When the cutter knife 10 is attached, the surface is fixed firmly with the fixing screw 3, and the cutter blade 10a is positioned at the guide surface 1a and the guide surface as shown in FIG. It is comprised so that it may become the same distance by the dimension X from 1b. In FIG. 3, the position of the cutter blade 10a when the cutter knife 10 is attached is illustrated by a two-dot chain line.

  In the cutting tool 1, the amount of projection of the cutter blade 10a of the cutter knife 10 from the bottom surface of the cutting tool 1 is adjusted by the slider 10b of the cutter knife 10, but the slider 10b is locked with a tick. If the position is adjusted, the cutter blade 10a may protrude too much.

  In that case, it is preferable to adjust the protrusion amount of the cutter blade 10 a by loosening the fixing screw of FIG. 3 and shifting the position of the cutter knife in the first groove 1 c of the construction tool 1.

  Although the embodiment in which the pressing means protrudes from the cutter blade 10a has been described with reference to FIG. 1, the same effect can be obtained even if the protruding dimension of the cutter blade and the protruding dimension of the pressing means are the same.

  The protruding state of the cutter blade 10a and the pressing portion 2a of the cutter knife 10 is the same as the position where the cutting edge of the cutter blade 10a abuts the object to be cut, that is, the straight line of the position of the cutting edge of the cutter blade 10a and the cutting tool 1 In this state, the position where the bottom surface of the pressing member 2 intersects with the corner on the bottom surface side of the tip of the pressing portion 2a. That is, the cutter blade is positioned at the corner on the bottom surface side of the tip of the holding portion 2a located on both sides of the cutter blade 10a and protrudes downward in the vertical direction from the bottom surface of the cutting tool in order to cut the object to be cut. In this state, the cutting edge 10a protrudes from the pressing portion 2a below the bottom surface of the cutting tool 1 even in a direction parallel to the surface of the cutting object. As a result, when used as a wallpaper construction tool, when cutting two commonly used wallpaper thicknesses, from the edge of the wallpaper without damaging decorative materials such as edges and baseboards. It becomes possible to adjust to the protrusion amount of the cutter blade 10a which is easy to cut to the end.

  Further, the protruding dimension in the direction parallel to the surface formed by the cutting object of the pressing means is slightly shorter than the protruding dimension in the direction parallel to the surface formed by the cutting object of the cutting edge of the cutter blade. However, it has been confirmed that the effect of the pressing means can be obtained, and when the cutting edge of the cutter blade protrudes, when cutting near the baseboard etc., cut the wallpaper exactly to the end be able to.

  Therefore, a configuration of pressing means for pressing the cutting object on both sides of the cutting edge of the cutter blade is projected in a state shorter than 1 mm with respect to the protruding dimension in a direction parallel to the surface of the cutting edge of the cutter blade 10a. It is also desirable to have a cutter blade protruding that can reliably cut two of the wall thicknesses that are commonly used for wall-cutting of wallpaper. .

  Further, FIG. 4 shows another embodiment of the pressing means, that is, the pressing portion. In the embodiment of FIGS. 1 to 3, the configuration of the embodiment in which the cutting tool 1 is bonded or pasted has been described. However, the pressing portion 20 may be provided integrally with the resin of the main body of the cutting tool. Good.

  In the case of manufacturing with resin, it is desirable to use a transparent resin so that the cutter blade 10a can be seen through, and lower than the height of the cutter blade 10a so that the operator can see the cutter blade 10a during use. This is also a desirable embodiment.

  In the case where the pressing means protrudes from the cutter blade 10a, the tearing can be prevented by effectively pressing the pressing means against the tearing of the wallpaper. And, at the boundary adjacent to the cutting object such as a peripheral edge or a baseboard, the wallpaper cannot be cut to the end, but the boundary is cut by moving the slider and slightly protruding the cutter blade 10a to cut the end. Can be cut.

In the case where the cutter blade 10a is slightly protruded from the pressing means, the effect of the pressing means is not obtained although the protrusion is shorter than the cutter blade, and the wallpaper near the blade edge is pressed. Therefore, the embodiment can be effective.
