Description

[Detailed explanation of the idea] (Symmetry of invention, industrial application field) The present invention is used in the field of cutting objects.

The present invention relates to a rug cutting tool that facilitates cutting the rug at the boundary between a floor surface and a wall surface when laying a rug such as a carpet.

(Prior art and its problems) When laying a rug on the floor, it is necessary to cut the rug along the boundary between the floor and wall, but it is difficult to cut exactly along the boundary, so it is difficult to cut the rug exactly along the boundary. I cut it long and then trimmed it along the border.

This is a waste of material as well as a waste of working time, and improvements in this point are desired.

As a cutting tool that has improved this problem, a semi-cylindrical cylinder or a part of a cylinder is installed horizontally on the edge of the slide with an upward opening, and the lower part of a blade plate with a blade attached thereto is rotatably attached to the cylinder. Japanese Utility Model Publication No. 1988-102 proposes a cutter in which the tip of the cutter protrudes from the cylindrical surface.

However, this cutting machine has the following drawbacks.

(a) When a rug is cut with the cutter described in Utility Model Publication No. 51-1021-, Figures 6 and 7 of the same publication
As shown in the figure, the bottom of the cut after cutting is cut deeper than the surface, but when cutting a cushion floor, which has an uneven surface, it is necessary to cut from the lower edge of the cut to the surface. Because the lengths to the upper edges of the concave and convex portions are different, the cut edge is not a straight line when viewed from above, and the convex portions are protruding and the concave portions are recessed, resulting in unevenness on the surface. It cannot be used for things that are present.

-(b) In the case of loop carpets, if the carpet is cut diagonally, the loops will be cut and the loops at the cut end will fall apart.

(C) The area of the rug that will become the corner of the room cannot be cut due to the distance from the knife to the left and right edges.

(Purpose of the present invention) The purpose of the present invention is to (a) ensure that the cut edges are straight even in carpets with uneven surfaces, such as cushion floors, and (b) that even in the case of loop carpets, the cut edges are straight. It is an object of the present invention to provide a rug cutting tool that satisfies the following requirements: (C) the rug does not fall into pieces, and (C) it can cut even the corners of a room.

(Structure of the invention) The technical means of the invention taken to distantly achieve the above object are as follows.

(a) A pressing member 3 having at least a curved surface in contact with the rug 9 is rotatably attached to the edge of the base 1; (b) the pressing member 3 has a longitudinal (e) A cutting edge protruding slot 6 is formed in the pressing member 3 over the entire length or substantially the entire length, and the cutter insertion opening 5 is formed at the position where the cutting edge is inserted. The contact edge 51 of the mouth 5 and the rotation center axis of the pressing member 3 are symmetrical or approximately symmetrical.

(Example) The present invention will be described in more detail based on an example shown in the drawings.

It should be noted that the present invention is not limited to the illustrated embodiment, and it goes without saying that many modifications can be made within the scope of the claims of the utility model registration.

FIG. 1 is a perspective view, and FIG. 2 is an enlarged partial perspective view showing the state of use.

Reference numeral 1 denotes a base, and a pressure receiving member 2 for receiving the force of pressing the cutting tool A against the wall surface 10 is erected on the base 1.

Note that this pressure receiving member 2 also serves as a holder when carrying the cutting tool A.

A pressing member 3 whose contact surface with at least the rug 9 is a curved surface is rotatably attached to the edge of the base 1 by a shaft 4 via a bearing 41 .

In this embodiment, a cylindrical body with both sides closed is used as the pressing member 3, but it is not necessarily limited to a cylindrical body, and in short, it is sufficient as long as at least the contact surface with the rug 9 is a curved surface. .

Note that the shaft 4 is made of, for example, a bolt, bolt, etc., and the pressing member 3 can be fixed by tightening these.

A knife insertion opening 5 is formed in the pressing member 3 over substantially the entire length or the entire length in the longitudinal direction.

In this embodiment, the width of the knife insertion opening 5 is formed to be slightly wide so that the knife 15 can move freely, but it may be at least wide enough to allow the knife 15 to be inserted and moved freely.

A cutting edge protruding slot 6 is provided at a position symmetrical or approximately symmetrical with respect to the contact edge 51 of the cutting tool insertion opening 5 and the central axis of the pressing member 3.
It is formed over substantially the entire length or the entire length of the pressing member 3 in the longitudinal direction.

In addition, when the blade insertion opening 5 and the cutting edge protruding slot 6 both extend over the entire length of the pressing member 3 in the longitudinal direction, a connecting member 7 as shown in the figure is required, for example, to prevent the pressing member 3 from separating.

The cutting edge protruding slot 6 preferably has a width that allows the cutting tool 15 to protrude and move freely in the longitudinal direction of the pressing member 3, and that the cutting tool 15 does not rattle.

This embodiment works as follows.

As shown in FIG. 2, the rug 9 is laid on the floor 11,
When cutting the rug 9 at the boundary between the floor surface 11 and the wall surface 10, press the pressing member 3 of the cutting tool A from above the rug 9 to the boundary between the floor surface 11 and the wall surface 10, and insert the knife 15 into the knife insertion slot 5. Insert
Protrude the cutting edge by the necessary amount from the cutting edge protruding slot 6, and then remove the cutting tool 1.
5 along the contact edge 51 and move the knife 15 to the left or right to cut the rug 9.

Note that there are thick and thin rugs 9, and the pressing member 3
When pressing against the wall surface 10, the distance between the wall surface 10 and the pressing member 3 will be different. The cuts cannot be made too close together.

Therefore, in the case of a thick rug, by turning the pressing member 3 in the direction B so that the cutting edge protruding slot 6 approaches the wall surface 10, the rug 9 can be cut into a long length, so that the cut surface and the boundary can be brought into close contact.

If the rug 9 is thin, it may be cut by turning the pressing member 3 in the C direction so that the protruding groove 6 approaches the floor surface 11.

(Effect of idea) The present invention has the following effects.

(1) Since a pressing member is attached to the edge of the base, at least the contact surface with the rug is a curved surface, so even if the rug is pressed against the boundary between the floor and the wall, the rug will not be suddenly pushed and bent. There is no damage to the material due to rug bending, etc.

(2) Since the pressing member is rotatable, the cutting length can be changed depending on the thickness of the rug.

(3) The contact edge of the cutter insertion opening formed in the pressing member and the cutting edge protruding slot are symmetrical or approximately symmetrical with respect to the rotation center axis of the pressing member, so the cutting surface is perpendicular to the rug surface or The cutting edge will be almost a right angle, and even if the surface of the rug is uneven, such as a cushion floor, the cut will be a straight line.

(4) Even if a line is not drawn when cutting the rug, the cut will be straight if it is cut along the protruding slot of the cutting edge.

(5) By aligning the edge of the protruding slot with the end of the cutting area on the rug, the rug will not be cut too much.

(6) The pushing member has a knife insertion opening formed over the entire length or almost the entire length in the longitudinal direction, and the cutting edge protruding slot is formed on the pressing member over the entire length or almost the entire length, so that You can also cut the corners of the room.

(7) The above eliminates wasted materials and shortens working time.
