DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for easily using a board such as a wall board, a ceiling board or a floor board in a building without any power at a construction site.
The present invention relates to a vertical board cutting tool (hereinafter, simply referred to as a board cutting tool) .

[0002]

2. Description of the Related Art Conventionally, gypsum board, thin plywood of up to about 6 mm in thickness, insulation board or compression board, etc., which has been hardened with an adhesive, and boards such as rock wool board have been specified at a construction site. In order to cut into dimensions, the work is generally performed by laying flat on a workbench or the like, placing a finger on the work surface, making a cut with a cutter knife or the like, then turning over, making a cut in the same place again, and then folding. Was. Of course, cutting is also performed with a saw, but gypsum board and the like are very dusty, and the workplace is extremely dirty due to sawdust and the working environment is deteriorated. Therefore, the cutting method using the cutter knife is excellent.

[0003]

However, a compression board having a relatively large thickness is, for example, 1 mm in thickness of 12 mm.
It weighs as much as 12 kg per sheet, and turning over the board is extremely hard work. Further, when cutting near the edge of the board, there is a drawback that it is not possible to break unless the cut is deep, and a considerable force must be applied to the knife, which has been a severely fatigued operation. It takes more time to cut,
There was also a problem that the cut part of the cut portion was not uniform and required post-processing.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems described above, and an object of the present invention is to provide a board cutting tool capable of obtaining a clean finish of a cutting edge in a short time while maintaining a good environment in which dust is not generated by light labor. Things.

[0005]

Resolving means larger size of the present invention According to an aspect of, for example 900 × 1,800mm Toka, particularly convenient stationary shaped board cutting tool for cutting in the longitudinal direction of the board such as 900 × 240 mm The structural feature is that a board moving means consisting of a base for moving a standing board in a substantially horizontal direction along a straight groove is stretched left and right at predetermined intervals.
The left and right opposing blades are supported at predetermined intervals on a pole that stands upright so that the board is clamped in the height direction from the base with the protruding stay , and the height of the opposing blade can be adjusted. Means.

[0006]

[0007] The stationary board cutting tool employs a method in which a board that is set up along a long straight groove is pushed and moved to cut the board, so that a heavy board can be cut particularly easily. The board moving means is provided with a large number of rollers in a straight groove or provided with support stays to the left and right for easy and stable movement. In addition, it should be foldable or plug-in type for convenient transportation and storage. A scale is provided on the column of the blade holding means so that the cutting dimension can be read directly at the position of the blade.

[0008]

[0009]

1 to 3 show an embodiment of a stationary board cutting tool, and FIG. 1 is an overall perspective view of the stationary board cutting tool. As is clear from FIG. 1, the board cutting tool of the present invention comprises a board moving means 4 comprising a base 3 for moving the board 1 in an upright state in a substantially horizontal direction along a straight groove 2, and a board moving means 4 in a height direction from the base 3. The opposing blades 5 are supported at predetermined intervals on the left and right while the board 1 is being clamped.
And blade holding means 6 capable of adjusting the height of the position.

In the straight groove 2 provided by the angle of the base 3 of the board moving means 4, a number of rollers 7 are arranged for smooth movement of the board 1 as shown in detail in FIG. Instead of the roller 7, a sliding tape such as a silicone resin, a fluororesin, or ultra-high molecular weight polyethylene may be used. In this case, the straight groove 2 is formed with the channel facing upward. Since the straight groove 2 is long, the base 3
May be detachable or foldable. The example of FIG. 1 is detachable and the joint is fixed with bolts and nuts. In order to maintain stability, stays 8 are extended right and left at a predetermined distance from the base 3.

The blade holding means 6 provided in the middle of the base 3 erects two poles 9 so as to clamp the board 1 standing along the straight groove 2 from right and left.
Use the as a guide to move up and down. Blade mounting block 10
And an adjusting bar 11 along a pole 9 for simultaneously adjusting the height of the left and right opposing blades 5 and a handle 12 above the adjusting bar 11. In order to fix the poles 9 and 9, a slanting support rod is used between the base 3 and the stay 8.
13 are provided. The pole 9 is provided with a scale 14 so that the cutting distance from the side edge of the board 1 can be read directly.

As shown in FIGS. 2 and 3, the blade mounting block 10 as the blade holding means 6 has two upper and lower blocks 10a, 1a.
0b, each of which has an insertion hole 15 for the pole 9 and a mounting groove 17 for the cutter knife 16, and has a bolt insertion hole on one side and a screw hole on the other side so that the blocks hold and hold the cutter knife 16. And integrated with bolts 18. Olfa (trade name) that can be used while cutting the cutter knife 16
Is preferred. The insertion hole 15 is provided with a clearance that is somewhat closer to or away from one or both of the opposing holes.
The gap 15 is adjusted by closely adhering the pole 15 to one of the right and left sides of the pole 9, leaving a gap on the opposite side, and inserting a spacer 19 there. In the case of FIG. 2, if the distance L between the blade mounting blocks 10 is 13 mm and the clearance C is 3 mm in order to correspond to a board having a thickness T of 9 mm and 12 mm, when the spacer 19 is moved to the right side of the pole 9, L = 13mm to 10mm
, And the clearance between the blade mounting blocks 10 and the board 1 can be maintained at 1 mm in any case. At this time, the interval D of the opposing blades 5 is set to 7 mm so that a cut of about 2.5 mm is made from the left and right on the board of T = 12 mm, and T =
A 9 mm board is also adjusted to D = 4 mm spacing. To adjust the height of the opposing blade 5 from the base 3, loosen the thumbscrew 20 provided on each of the opposing blocks 10 a, and adjust the height of the adjusting bar 11 along with the blade mounting block 10 along the pole 9 to the scale 14 with the handle 12. After that, it is fixed by the thumb screw 20.

[0015]

As described above, the board cutting tool of the present invention has a structure as described above. Therefore, in the case of a stationary type, the board can be cut lightly and accurately by simply standing on the straight groove of the base and pushing between the opposed blades. Yes, it can be cut easily by pulling it on the edge of the board with the straight groove of the base. At the time of cutting, only the cut is made from both sides, so that the cut portion is not forced, and the board can be cut cleanly by pressing the board surface by hand after the cut. Therefore, it is possible to maintain a clean and dust-free environment efficiently with less labor and sanitary.
