Description

  The present invention lays an end of a sheet-like floor material laid on the floor surface so as to mold the end portion along the corner portion of the floor surface and the wall surface, or to press it along the corner portion. Related to tools.

Conventionally, a resin sheet-like floor material or the like is laid on the concrete floor surface or the like in order to enhance the design.
The sheet-like flooring is usually laid toward the opposite wall from one wall, and the remaining part of the sheet-like flooring is cut, and the cutting edge is placed on the lower end of the opposite wall (baseboard etc.) and the floor It is made to correspond to the corner with the surface.

  As a method of cutting the sheet-like floor material so as to coincide with the corner between the lower end of the opposite wall and the floor surface, as long as the sheet-like floor material is thin and easily bent, as shown in FIG. The surplus portion of the sheet-like flooring 100 is bent into an L shape so that the bent portion is along the corner 400 between the lower end 200 of the wall and the floor surface 300, and the L-shaped bent portion is cut with the cutter 500. The cutting edge can be made to coincide with the corner between the lower end of the opposite wall and the floor (for example, see Patent Document 1).

  In the case of a sheet-like floor material made of a resin-made multilayer structure or a sheet-like floor material made of a hard resin, if the sheet-like floor material is bent into an L shape as described above, delamination, cracks, etc. at the bent portion May occur, and the cutting edge may not be well aligned with the corner between the lower end of the wall and the floor.

  Therefore, conventionally, as shown in FIG. 7, a laying tool 700 in which a pressing roller 720 whose peripheral surface has a predetermined R shape is rotatably provided on the side surface of the handle portion 710 is prepared, and the surplus of the sheet-like flooring is prepared. By rolling the pressing roller 720 along the lower end 200 of the wall while sandwiching a part of the sheet-like flooring 100 between the lower end 200 of the wall and the floor surface with the pressing roller 720 of this laying tool, Once the portion of the sheet-like flooring facing the corner between the floor surface and the lower end 200 of the wall is shaped to have the R shape of the pressure roller 720, for example, although not shown, the sheet-like flooring Using a commercially available cutter device (such as Perfect Cutter (trademark) of Hiroshima Co., Ltd.) equipped with an R-shaped guide portion that conforms to the 100-R shape, the sheet is formed along the R-shaped ridge line of the shaped portion of the sheet-like flooring. Condition And so as to cut the wood.

Further, as shown in FIG. 8, first, a face wood 800 is installed at a corner portion between the floor surface 300 and the lower end 200 of the wall. There is also a laying structure of the sheet-like floor material 100 in which dust or the like is prevented from collecting at the corner portion between the indoor floor and the wall.
In such a laying structure, the sheet-like flooring 100 is laid from the floor surface 300 to the upper end of the facepiece 800 via an adhesive, and the pressing roller 720 of the laying tool 700 is rolled while being rolled. 100 is pressed against the face wood 800, and the sheet-like flooring 100 is firmly adhered to the face wood 800 with an adhesive.

  By the way, in the conventional laying tool 700, a screw hole is formed in the side surface of the handle portion 710, and the screw roller provided at the tip of the shaft pin of the pressure roller is screwed into the screw hole so that the pressure roller 720 is attached to the shaft pin. Via the handle portion 710 so as to be freely rotatable. Also, when screwing the screw part into the screw hole of the handle part, an adhesive is applied to the screw part, and the screw does not loosen due to friction or vibration caused by the rotation of the pressing roller 720 in use by the adhesive so that the shaft pin does not come off. I have to.

  On the other hand, when the sheet-like floor material is cut according to the corner, the R shape to be shaped differs depending on the material and structure of the floor material. In addition, the size of the faceplate and the R shape vary. Accordingly, various R-shaped pressing rollers are required.

  However, as described above, in the conventional laying tool 700, since the shaft pin is fixed to the handle portion 710 with an adhesive, the pressing roller 720 cannot be replaced. Therefore, it is necessary to prepare a plurality of laying tools having different shapes of the pressing rollers, which is costly and problematic in terms of storage space.

JP-A-5-138586

  In view of the above circumstances, the present invention easily and inexpensively molds the end portion of a sheet-like floor material laid on the floor surface into a plurality of different R shapes or presses them along a plurality of different R shape corner portions. It aims to provide a laying tool that can do.

  In order to achieve the above object, a laying tool according to claim 1 of the present invention (hereinafter referred to as "laying tool of claim 1") is provided with a pressing roller rotatably on a side surface of a handle portion, By rolling the pressing roller along the lower end of the wall, the end of the sheet-like flooring laid on the floor is molded along the corner between the floor and the lower end of the wall, or the corner is In the sheet-like flooring laying tool that presses along, the pressing roller is supported by the handle portion in a replaceable manner.

  The laying tool according to claim 2 of the present invention (hereinafter referred to as "laying tool of claim 2") is the laying tool according to claim 1, wherein the pressing roller is a frictional resistance to the bearing portion due to the rotation of the pressing roller.
