Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor material scoring tool used for scoring work in which a scoring line is drawn on a floor material along the shape of a wall surface.

[0002]

2. Description of the Related Art When laying various floor materials such as floor tiles, cushion floors, sheets, carpets, mats, artificial stone floor materials and wood floor materials on the floor surface, the standard It is necessary to cut the floor material according to the shape of the construction site, for example, at the construction site,
The end of the floor material laid on the side of the wall is cut along the shape of the wall so as to fit the wall shape of the room.

Conventionally, when performing such cutting, scoring is performed with a width ruler, a scriber or the like, and a desired shape is cut with a cutting tool such as an NT cutter while applying a metal ruler or the like according to the scoring line. However, in such a method, it may be impossible for anyone to draw a scoring line accurately and efficiently. For example, when performing a scoring work in a narrow stairs or other places with poor scaffolding, a high degree of skill and skill are required, and an inexperienced person or an inexperienced person cannot efficiently perform the scoring work.

Specifically, in general, a scoring width (also referred to as a scoring allowance) is used from the viewpoint of avoiding the generation of waste scraps as much as possible.
It is preferable that the length is as short as possible, but when constructing plastic tiles on the stairs of the stairs, in order to draw the scoring lines so that the scoring width becomes short, it is necessary to be extremely close to the wall of the stairs. It is very difficult for an unskilled person to perform such work on narrow stairs. On the other hand, if the scoring width is made longer, the scoring work becomes relatively easy, but on the other hand, not only wasteful scrap materials increase, but also large tiles must be prepared in consideration of the scoring width (mill scrap). Therefore, when performing a scoring operation on the floor surface, at least the tile end portion corresponding to the scoring width protrudes from the nose, and the operator may erroneously damage this portion. In order to prevent this damage, generally, the scoring width may be set to about 1 cm.
As mentioned above, it is difficult for an inexperienced person to perform such a scoring work, and on the other hand, even for a skilled person, a scoring line having such a short scoring width is a well-known tool such as the above-mentioned width ruler or scriber. It is difficult to pull with.

Under these circumstances, in practice, in places where it is difficult to work, such as stairs, a skilled person can pierce a plywood board or the like with an awl and make an ad-hoc scoring tool to perform scoring work. Although it is carried out, only a skilled person can make and use this tool, and there is a disadvantage that the skilled person takes time to make the tool. Therefore, there is a demand for a scoring tool that allows anyone to easily perform scoring work in a narrow space.

As a tool for marking the floor material, a width ruler device disclosed in Japanese Patent Laid-Open No. 146557/1993 is known. However, the one disclosed in this publication is intended to accurately reflect the shape of the wall surface on the scoring line, and in such a device, the mounting portion such as the scoring pin contacts the wall surface. Since it is fixedly provided at a position relatively distant from the abutting member, the scoring width cannot be shortened if necessary, and two abutting members (first Since the abutting member and the second abutting member) are respectively brought into contact with the wall surface, at the time of the scoring work, scoring cannot be performed unless the entire apparatus is translated with respect to the wall surface, so that it is possible to use in a narrow space. It is difficult to do the scoring work in such as a circle, and it is impossible to draw the scoring line in the place where it is necessary to scribe in a circular shape such as around a small diameter cylinder. It is inferior in sex.

In view of the above points, it is a first object of the present invention to provide a floor material scoring tool which can easily perform scoring even in a difficult place such as a narrow place.
Further, it is a second object to provide a floor material scoring tool capable of drawing scoring lines so as to have scoring widths of various lengths as needed.

[0008]
