However, when the shape of the floor is complicated due to the protrusion of the pillar, it is troublesome to measure the shape of the floor and cut the carpet.
In order to solve the above-described problems, an object of the present invention is to provide a carpet ruler that easily copies a complicated floor shape and makes it easy to draw a carpet.

In order to solve the above-described problems, the first invention is a group of plates in which a large number of linear strips having a constant width are bound, a binding means for performing the binding, an adjusting means for adjusting the strength of the binding, This is a carpet ruler.
The second invention is a carpet ruler characterized in that the binding means further comprises a belt, and the adjusting means has a mechanism for adjusting the tension of the belt.
According to a third aspect of the present invention, the bundling means is a frame that surrounds the plate group in the thickness direction, and the adjusting means includes a presser plate disposed inside the frame and parallel to the long side of the frame, A carpet ruler having a screw provided on a long side of the frame in order to move the pressing plate and press the plate group.
According to a fourth aspect of the present invention, there is provided the carpet ruler, wherein the plate member is provided with a ruler needle projecting in a direction perpendicular to the plate thickness portion at the tip thereof.

  According to the first, second, third, or fourth invention, the carpet ruler of the present invention is placed in a state where the front end of the plate group can come into contact with the part where the floor shape is complicated, and the adjusting means By weakening the binding strength, each plate can be moved, and by pushing the plate group by hand in the longitudinal direction of the plate, the plate material moves greatly where the floor shape is recessed and protrudes However, it moves a little. Thereby, the shape of the floor can be copied in the shape drawn by the tip of the plate group. After that, the adjustment means increases the binding strength so that each board cannot move, and if the carpet ruler is placed on the carpet, it can be easily drawn along the shape drawn by the end of the board group. Can be done.

Further, according to the second or third invention, the manufacturing cost of the carpet ruler can be suppressed with a simple configuration.
Further, according to the fourth invention, after copying the shape of the floor, the binding means is strengthened by the adjusting means so that the plates cannot be moved, the carpet ruler is turned over, and on the back side of the carpet. By placing, striking the tip of the group of plates, or pressing, the marks of the ruled needles are marked on the back of the carpet and can be drawn easily without using a pen.

An embodiment of the present invention is shown in FIGS.
As shown in FIGS. 1 (A) and 1 (B), the carpet ruler 1 according to this embodiment is configured by stacking a large number of straight and long rectangular metal plate members 3 in a plate thickness direction with a constant width, It has the board group 5 bound. The plate member 3 has, for example, a thickness of 2 to 3 mm, a width of 20 mm, and a length of 300 to 400 mm. If the binding force is weak, the plates can slide while touching each other. The bundling means 7 for bundling includes a steel belt 9 for winding the plate group 5 in the plate thickness direction.

  As shown in FIG. 2, the adjusting means 11 for adjusting the binding strength has a mechanism for adjusting the tension by pulling the belt 9. That is, the U-shaped metal fitting 13 is attached to one end of the belt 9 so as to be rotatable around both ends of the U-shape. A substantially square tongue-shaped metal plate 15 is attached to the other end of the belt 9 so as to be rotatable about the tip. The metal plate 15 is formed with ears 17 for hooking the U-shaped metal fitting 13 on both sides. When the ear portion 17 is tilted while the U-shaped metal fitting 13 is hooked, the U-shaped metal fitting 13 is once stretched by a strong tension and then contracted, and both ends of the belt 9 are strongly pulled. Can unite.

  As shown in FIG. 1 (C), each plate member 3 has a ruled needle 21 projecting from a plate thickness portion 19 at the tip thereof upward in a direction perpendicular to the plate thickness portion 19.

"how to use"
In order to use the carpet ruler 1, first, the carpet ruler 1 is placed on the floor in a state where the front end of the plate group 5 can come into contact with a portion where the floor shape is complicated due to the protrusion of the column 28. 30. And the tongue-shaped metal plate 15 which comprises the adjustment means 11 is raised, the both ends of the belt 9 are released | separated, and the strength of binding is weakened. This allows each plate to move. Then, the plate group 5 is pushed by hand in the longitudinal direction of the plate toward the wall or column.

If it does so, the board | plate material 3 of the place in which the shape of the floor is dented will move large, and the board | plate material 3 of the protruding part will move a little. Thereby, each board moves to each. Thus, the shape drawn by the tip of the plate group 5 represents the shape of the floor (FIG. 1A).
Thereafter, the tongue-shaped metal plate 15 constituting the adjusting means 11 is tilted down, and both ends of the belt 9 are drawn together to increase the binding strength. This prevents each plate from moving. Then, the carpet scribing tool 1 is placed on the carpet 31, and the marking can be easily performed with a magic pen or the like along the shape drawn by the tip of the plate group 5.

Alternatively, after copying the shape of the floor, the adjusting means 11 increases the binding strength so that the plates cannot move, and the carpet ruler 1 is turned over and placed on the back side of the carpet 31 (FIG. 1). (B)). Then, the end of the plate group 5 is struck with a hammer, stepped on with a foot, pressed strongly with a hand, and the trace of the ruled needle 21 (see FIG. 1C) is behind the carpet 31. Marked with As a result, ruled lines can be easily drawn without using a magic pen or the like.
The ruler needle 21 also serves as a stopper for preventing the plate material 3 from coming off the binding means 7.

"Effect of the embodiment"
According to this embodiment, it is possible to easily copy a floor shape complicated by a protruding pillar or the like without using a ruler or the like, and to easily perform ruled drawing for cutting a carpet. .

"Other embodiments"
In the above embodiment, the bundling means 7 has the belt 9 and the adjusting means 11 has a mechanism for adjusting the tension of the belt 9, but in other embodiments, for example, FIG. As shown in FIG. 4, the bundling means 7 is a frame 23 surrounding the plate group 5 in the thickness direction, and the adjusting means 11 includes a presser plate 25 disposed inside the frame 23 and parallel to the long side of the frame 23. ,can do.

That is, as shown in FIGS. 3B and 3C, two screws 27 are provided on the long side of the frame 23, and the tip 29 of the screws is loosely fitted on the upper surface of the holding plate 25 so as to be rotatable. Has been. When each screw 27 is tightened, the tip 29 of the screw is lowered, and the presser plate 25 is moved downward to press the plate thickness portion 19 of the plate group 5 (FIG. 3B). By adjusting each screw 27, the pressing force can be adjusted, and thus the strength of binding can be adjusted.
In another embodiment, the adjusting means may be one or a plurality of wedges driven between the plate members of the plate group.
