[Industrial applications]

 TECHNICAL FIELD The present invention relates to a cutting tool used for cutting a corrugated cardboard curing sheet, which is attached to protect an exposed surface of a new house, to a predetermined size.

[0002]

[Prior Art]

 Curing sheets are made of corrugated cardboard, shipped in rolls, and cut to the required length on site. Conventionally, as this cutting method, a method of inserting an underlay such as a veneer plate under the stretched sheet as shown in Fig. 13 and holding the sheet with a ruler-like material from above and cutting with a cutter, He used scissors and a hook-shaped cutter.

[0003]

[Problems to be solved by the device]

 However, the method of FIG. 13 is troublesome because the underlay must be moved one by one and it is necessary to check whether the underlay is underneath. Also, the fist that holds the scissors is an obstacle for hand scissors, making it unsuitable for long cutting. Moreover, the seat must be left floating. In the case of a hook-shaped cutter, it is not possible to hold the sheet with a ruler, so the sheet may be wrinkled, the cut surface may bend easily, and the floor material may be damaged depending on the angle of the cutter. ..

[0004]

[Means for Solving the Problems]

 The present invention uses the following means to solve the above problems. That is, in the cutter that cuts the curing sheet, the cutter handle is projected in an inclined manner from the tapered cutter base, the cutter blade is inserted into the cutter blade groove provided at the base of the cutter handle, and the base of the cutter handle is inserted. It has a projection to hold the sheet in front of the cutter blade.

[0005]

The problems to be solved by the present invention and the means for solving the problems are as described above. Next, the embodiments of the present invention shown in the accompanying drawings will be described. FIG. 1 is a perspective view of a curing sheet cutter A of the present invention, FIG. 2 is a cross-sectional view near the blade holding protrusion 3a of the cutter handle 3 of the curing sheet cutter A, and FIG. 3 is a side view of the curing sheet cutter A. 4 is the same bottom view, FIG. 5 is a plan view seen from the Y direction in FIG. 3, FIG. 6 is a front view seen from the X direction in FIG. 3, and FIG. FIG. 8 is a perspective view showing a state in which the curing sheet S in a close contact state is cut, FIG. 8 is a perspective view showing a state in which the curing sheet S in the same floating state is cut, and FIG. 9 is a curing sheet S in the same packed state. 10 is a perspective view showing a state of cutting the sheet, FIG. 10 is a perspective view of the curing sheet cutter B 1, FIG. 11 is a front view seen from the X ′ direction in FIG. 10, and FIG.

As an example of a curing sheet cutter of the present invention, a curing sheet cutter A shown in FIGS. 1 to 9 and a curing sheet cutter B shown in FIGS. 10 to 12 will be described. ..

First, the curing sheet cutter A will be described. Resin is used as the material for the curing sheet cutter A 1. The cutter table 1 is tapered and has a shape that makes it easy to catch the edge of the curing sheet S as shown in FIG. A cutter blade case 2 is attached at the center of the upper side of the cutter base 1 on the side opposite to the X side, and a cutter handle 3 is provided so as to project obliquely upward from the upper portion. Then, the cutter blade groove 4 is provided so as to extend from the upper end of the cutter handle 3 to the cutter blade case 2 and the cutter base 1.

In the cutter blade groove 4, in the portion of the cutter handle 3, a blade holding projection 3a is provided as shown in FIG. 2 so that the cutter blade C fitted in the cutter blade groove 4 does not shake. The cutter blade groove 4 exposes the cutter blade in the cutter blade case 2. The vertical width of the exposed portion is slightly larger than the thickness of the curing sheet, so that the curing sheet can be reliably cut. Also, the cutter blade case 2 has the same thickness as the cutter handle 3 on the side opposite to the X side, but is thin on the side of the cutter blade C, so that the sheet cut by the cutter blade C does not interfere with the next cutting. It has a function to open on both sides.

Since the bottom of the cutter blade groove 4 is located inside the cutter base 1, the cutter blade does not damage the floor. It should be noted that the floor scratches can be further prevented by sticking felt or the like on the bottom surface of the cutter table 1. Further, a blade replacement hole 1a is formed from the bottom surface of the cutter base 1 to the bottom of the cutter blade groove 4. The blade replacement hole 1a is configured to insert a screwdriver or the like to push up the cutter blade C in the cutter blade groove 4 and remove it.

The cutting is performed by grasping the cutter handle 3 and pulling it in the X direction. The problem when cutting is that the cut sheet rises and the sheet to be cut next rises and rises. For this reason, the sheet holding protrusion 3b is provided at the base of the cutter handle 3 at the front side of the exposed portion of the blade in the cutter blade case 2 to prevent the sheet from rising and guide the cutter correctly. .. The sheet pressing protrusion 3b also has a function of protecting the finger of the hand holding the cutter handle 3 from being accidentally touched by the cutter blade and being damaged. 3c is a string hole for storing the cutter.

By configuring the curing sheet cutter A as described above, even when the curing sheet S is in close contact with the floor as shown in FIG. 7, for example, when the curing sheet S is floating as shown in FIG. With the functions of the cutter base 1 and the sheet pressing protrusion 3b, the sheet can be surely and quickly cut without floating the sheet and without damaging the underlying floor or sheet. Further, as shown in FIG. 9, the curing sheet S is rolled when packed, but the curing sheet cutter A is a sheet wound without damaging other parts of the sheet wound by the cutter base 1. It is also possible to disconnect.

Next, an example of the curing sheet cutter B will be described. The curing sheet cutter B can be constructed to be about handmade, and the cutter base 5 or the cutter handle 6 may be made of wood, ABS resin or the like. The cutter base 5 is tapered like the cutter A for the curing sheet. Grooves 5a and 6a for mounting the cutter blade case 7 are dug in the side surfaces of the cutter table 5 and the cutter handle 6, and the cutter blade case 7 is embedded in the groove and fixed with a screw or the like to fix the cutter table 5 And connect the cutter handle 6. The cutter blade case 7 is formed by bending a steel plate into a U shape so that the tip of the cutter blade can be inserted as shown in FIG. A groove 5b for attaching a cutter blade is provided on the side surface of the cutter table 5, and a screw hole 5c for inserting a butterfly screw 8 for fixing the cutter blade is also formed. The cutter blade C is embedded in the groove 5b with the blade facing upward, the tip is inserted into the cutter blade case 7, and the hole already provided in the cutter blade C is aligned with the screw hole 5c and fixed by the butterfly screw 8. If the U-groove of the cutter blade case 7 is crushed at the portion 7a immediately below the inserted cutter blade C, the cutter blade C will not scrape down. The portion of the base of the cutter handle 6 immediately in front of the cutter blade C constitutes a projection 6b for safety and sheet restraint as in the case of the curing sheet cutter A.

Since the curing sheet cutter B is configured as described above, pulling in the direction of the arrow X ′ in FIG. 10 does not bend the sheet cutting surface, so that the curing sheet can be quickly cut. In each case of the curing sheet S as shown in FIGS. 7 to 9, the same function as that of the curing sheet cutter A is exerted, and a quick and reliable cutting can be performed without damaging other portions.

[0014]

[Effect of the device]

 Since the present invention has the above-described structure and embodiment, it has the following effects. Since the curing sheet cutter of the present invention has the cutter base, the cutter blade does not damage the floor material, and the taper of the seat base makes it possible to easily grasp the sheet edge. In addition, by forming a protrusion just before the cutter blade at the base of the cutter handle, it is safe that the fingers of the hand holding the handle do not touch the blade, and moreover, the lifting of the sheet is suppressed, and the cutting surface is bent quickly. A reliable cutting is possible.
