Description

  The present invention relates to a cutting tool for synthetic resin floor materials such as linoleum and vinyl chloride.

  Conventionally, there is a floor material cutting tool that cuts another floor material with a line to be a seam while a guide portion is brought into contact with an end surface of the existing floor material. Since the cutting tool for flooring described in Patent Document 1 becomes a hindrance when the cutting tool is set on the flooring to be cut, the cutting blade can be slid by moving the blade mounting part up and down. The cutting tool can be set by moving it upward. In order to move the cutting blade upward, a blade position adjustment mechanism is formed at the tip of the support, and a slide block is formed that is slidably fitted to the blade position adjustment mechanism. A blade mounting portion is formed on the block, and the cutting blade is moved by sliding the blade mounting portion in the vertical direction. Here, as a matter of course, it is necessary to fix the cutting blade at a predetermined position, but the fixing means is tightening with a screw. Therefore, every time the cutting blade is moved up and down, the work of loosening the screw and the work of tightening are indispensable, and much labor is required.

  When setting the cutting tool on the floor material to be cut, the work of moving the cutting blade upward and cutting the cutting blade into the floor material to return it to the original position can be done with one touch without much trouble. An object of the present invention is to provide a floor material cutting tool that can be used.

  The first aspect of the present invention is to cut the floor material in which the guide portion is brought into contact with the end face of the existing floor material, the cutting blade is cut into the floor material to be cut, and the floor material is cut while being slid and cut along the joint line. A cutting tool including a main body and a rotating member hingedly connected to the main body, wherein the main body has a lower plate portion and the guide portion, and the rotating member is detachably attached. It has a blade, and the floor member placed on the upper surface of the lower plate portion is cut from the upper surface by the cutting blade by rotating the rotating member downward about the hinge.

According to a second aspect of the present invention, an element provided with means for restricting the rotation of the rotation portion is added to the first embodiment in order to maintain a constant distance between the rotation member and the lower plate portion. It is.

According to a third aspect of the present invention, an element in which the rotating member has a grip portion is added to the first or second aspect.

According to a fourth aspect of the present invention, an element in which the hinge coupling is a hinge coupling by a hinge is added to any one of the first to third aspects.

A fifth aspect of the present invention is a configuration in which an element having means capable of adjusting the width of the gap between the existing floor material and the cut floor material is added to any one of the first to fourth aspects. Further, in the sixth aspect of the present invention, an element provided with means for moving and fixing the rotating member and the cutting blade attached thereto in a direction perpendicular to the sliding direction of the cutting tool is added to the fifth aspect. It is.

The first aspect of the present invention is to cut the floor material in which the guide portion is brought into contact with the end face of the existing floor material, the cutting blade is cut into the floor material to be cut, and the floor material is cut while being slid and cut along the joint line. A cutting tool including a main body and a rotating member hingedly connected to the main body, wherein the main body has a lower plate portion and the guide portion, and the rotating member is detachably attached. By having a blade and rotating the rotation member downward about the hinge, the floor material placed on the upper surface of the lower plate portion is cut from the upper surface by the cutting blade. Therefore, when the cutting tool is set on the floor material to be cut, the operation of moving the cutting blade upward and cutting the cutting blade into the floor material in order to return it to the original position only needs to rotate the rotating member. It can be done with one touch without any hassle. Thus, the movement of the cutting blade is only a turning operation of the turning member, and a troublesome work such as loosening and tightening of the screw is unnecessary.

According to a second aspect of the present invention, there is provided means for restricting the rotation of the rotating portion in order to maintain a constant distance between the rotating member and the lower plate portion. Therefore, even when the rotating member is strongly pressed from above when the flooring is being cut, the flooring can be smoothly cut without being pressed.

According to a third aspect of the present invention, the rotating member has a grip portion. Therefore, since the operation can be performed while holding the holding portion, the cutting tool can be easily moved during cutting.

According to a fourth aspect of the present invention, the hinge connection is a hinge connection using a hinge. The hinges are made so strong that they can withstand long-term use.

Claim 5 has means that can adjust the width of the gap between the existing floor material and the cut floor material, and claim 6 includes a rotating member and a cutting blade attached to the rotating member. Means for moving and fixing in a direction perpendicular to the sliding direction is provided. In any case, the width of the gap of the seam can be increased. Accordingly, the work performed by the grooving cutter for forming a groove having a U-shaped or V-shaped cross section at the seam portion originally forms a part of the groove when the seam has a slightly wider gap. Can be done efficiently and easily.

FIG. 1 is a plan view of the present invention. FIG. 2 is a front view of the present invention. FIG. 3 is a side view of the present invention. FIG. 4 is a view showing a state in which the turning portion is turned upward. FIG. 5 is an explanatory diagram of a state in which the floor material is cut. FIG. 6 is a bottom view of the present invention. FIG. 7 is a view showing the shape of the through hole of the upper plate portion.

  Next, an embodiment of the present invention will be described. The main body 1 includes a lower plate portion 2, an upper plate portion 3, and a spacer 4 for keeping the interval between the lower plate portion 2 and the upper plate portion 3 constant. The lower plate portion 2 is a portion that comes into contact with the floor material when the cutting tool is slid on the floor material, and a sheet 5 having a fluororesin film is bonded to the lower surface of the lower plate portion 2 in order to improve sliding. Yes. The lower plate portion 2, the spacer 4 and the upper plate portion 3 are preferably formed of a metal such as stainless steel or aluminum. The lower plate portion 2, the spacer 4 and the upper plate portion 3 are each provided with a through hole for coupling, and a bolt and a nut 6 with the lower plate portion 2 and the upper plate portion 3 passing through the through hole with the spacer 4 interposed therebetween. Are combined. The coupling through holes provided in the lower plate portion 2 and the spacer 4 are round holes (not shown), but the through holes 21 and 21 provided in the upper plate portion 3 are long holes as shown in FIG. It is. The reason for the long hole will be described later.

  The rotating member 7 includes a rotating plate 8 and a grip portion 9 fixed to the rotating plate 8. The rotating plate 8 is preferably formed of a metal such as stainless steel or aluminum, and the grip portion 9 is preferably formed of hard wood. The rotating plate 8 is connected to the upper plate portion 3 by a hinge 10. By this hinge connection, the rotating plate 8 can be rotated up and down with respect to the upper plate portion 3. Further, since the rotation plate 8 and the upper plate portion 3 have a certain thickness, the end surfaces of the rotation plate 8 and the upper plate portion 3 are pressed against each other when the rotation member is rotated downward. Thus, the rotation of the rotating plate 8 is restricted. As a result, a constant interval is maintained between the rotating member 7 and the lower plate portion 2. As shown in FIG. 2, the rotation of the rotation plate 8 is restricted in a state where the rotation plate 8 and the upper plate portion 3 are both horizontal.

  The grip 9 is fixed to the rotating plate 8 along the end of the rotating plate 8. Adherence is due to an adhesive. The grip portion 9 is fixed to the rotary plate 8 so that the end surface 11 of the rotary plate 8 and the outer surface 12 of the grip portion 9 are flush with each other. The reason why the end surface 11 of the rotating plate 8 and the outer surface 12 of the grip portion 9 are flush with each other is that the cutting blade 13 is sandwiched and attached by a part of this surface and a separate pressing plate 14. Through holes for inserting bolts 22 and 22 are respectively provided in the grip portion 9 and the press plate 14, and the bolts 22 and 22 and nuts are held in a state where the cutting blade 13 is sandwiched between the grip portion 9 and the press plate 14. Fasten with 15 and 15 and fix. When exchanging the cutting blade 13, the bolt and nut are loosened and the old cutting blade is removed. It is preferable to use what cut | disconnected the cutting blade 13 by the broken line provided in the replacement blade of the cutter knife.

  Next, the usage method of this invention is demonstrated. First, as shown in FIG. 4, the guide portion 18 of the main body 1 is applied to the end surface 20 of the existing flooring 17 installed on the floor 16. Next, the rotating member 7 is rotated upward, and the floor material 19 to be cut is placed on the upper surface of the lower plate portion 2. Next, as shown in FIG. 5, the rotating member 7 is rotated downward, and the cutting blade 13 is cut into the floor material 19. When the rotating plate 8 becomes horizontal, the cutting blade 13 is completely cut into the floor material 19, and the tip of the cutting blade 13 protrudes downward from the lower surface of the floor material 19. Then, the rotation member 7 is restricted from moving further downward. In this state, the flooring 19 can be cut along the seam line by placing a hand on the grip 9 and sliding the cutting tool along the end surface 20 of the existing flooring 17.

In addition, as shown in FIG. 7, the through-holes 21 and 21 provided in the upper board part 3 are long holes. Since it is a long hole, the upper plate part 3 can be moved and fixed to the right side in FIG. 1 by loosening the nut 6. This means that the floor 19 can be cut by moving the cutting blade 13 to the right and fixing it. Since the cutting line of the flooring 19 is moved to the right side by moving the cutting blade 13 to the right side, when the flooring 19 is cut and placed on the floor, the end surface of the flooring 19 and the existing flooring 17 A slightly wider gap is formed between the end face 20 and the end face 20. Usually, as a process of the seam portion between flooring materials, a U-shaped or V-shaped groove is formed in the seam portion with a grooving cutter, and then, for example, vinyl chloride or olefin welding is performed by a hot air welding machine. Perform hot air welding using a rod. In addition, for example, an epoxy filling material is filled in the groove and cured, and finally the seam portion is flattened. The above-described work performed by the grooving cutter that forms a U-shaped or V-shaped groove in the joint portion is that a part of the groove is originally formed when the seam has a slightly wider gap. Efficient and easy to do. As a result, a slightly wider gap may be formed at the seam.

  In addition, this invention can take a various aspect based on the structure mentioned above. For example, the lower plate portion 2 and the spacer 4 may be formed integrally, or the lower plate portion 2, the spacer 4 and the upper plate portion 3 may be formed integrally.

  When setting the cutting tool on the floor material to be cut, the operation of moving the cutting blade upward and cutting the cutting blade into the floor material to return it to the original position is only the rotation of the rotating member. It can be done with a single touch without any additional costs.
