Description

  In the floor structure in which a wooden sill is provided between a room in which a tatami is laid and a wooden finishing material, for example, a flooring board-finished hallway or a Western-style room, the wooden material is stretched, shrunk, or warped. In order to cope with this, it relates to a threshold closing provided between a threshold and a wooden finish.

Wood materials, for example, flooring board finish floors that are provided between floor materials that expand and contract due to changes in humidity in the air, eliminate gaps caused by expansion and contraction, and prevent accumulation of dust in the gaps. A “flooring out” is known (see Patent Document 1).
Japanese Unexamined Patent Publication No. 2002-70302 (first page, FIG. 1)

  However, wood is generally used for the sill of a tatami room, and if the outside corridor or another room of this sill has a flooring board finish, it is also between the sill and the flooring floor. Since gaps are formed, it has been known that a rubber material or a caulking material is provided.

There was a gap between the wood-based sill and the wood-based finishing material of the floor due to the expansion and contraction of the wood-based material due to changes in humidity, and dust could enter the gap. Moreover, the sill side end face of the finishing material of the floor may be warped, and the flatness between the sill and the floor may not be maintained. In particular, particle board is widely used as a base material for floor finishing materials. However, if such a base material is used, both the finishing material and the base material are made of wood, so the amount of shrinkage increases and defects increase. There was a risk. When the wood-based material expands and contracts by about 5 to 10 mm, a conventional rubber material or a caulking material cannot be used.

  In view of this, the present invention provides a gap between the wood-based sill and the wood-based finishing material so as to prevent gaps from accumulating in the gaps by creating a gap corresponding to expansion and contraction or warping caused by a change in humidity of the wood-based material. The purpose is to provide a possible threshold.

    In order to achieve the above-mentioned object, the present invention is a sill part provided between a wood-based sill and a wood-based finishing material, and a base member having a receiving port on the upper end side is fixed to the sill side surface. A lid member is formed from an eaves portion that extends from the upper end of the insertion portion to cover the one end side surface of the wood-based finishing material. A close contact portion formed of a soft thermoplastic elastomer is provided along the longitudinal direction on the lower surface of the eave portion of the lid member, and the close contact portion is in close contact with the surface of the wood-based finishing material.

  This invention is a sill part provided between a wood-based sill and a wood-based finishing material, and a base member having a receiving port on the upper end side is fixed to the side surface of the sill and is inserted into the receiving port of this base member. The lid member is formed from an eaves portion extending from the upper end of the insertion portion so as to cover the one end side surface of the wood-based finishing material, and is formed longitudinally on the lower surface of the eave portion of the lid member. When a sticking part made of a soft thermoplastic elastomer is provided along the direction and this sticking part is in close contact with the surface of the wood-based finishing material, the wood-based material stretches or warps due to humidity changes Even so, it is possible to prevent inconveniences such as a gap between the sill and the wood-based finishing material and accumulation of dust in this gap. In addition, the lid member is a synthetic wood molded from a thermoplastic resin material mixed with wood powder, so it matches well with wood-based sills and wood-based finishing materials, has a good appearance, and is excellent in strength. It will be. Moreover, since it is excellent also in strength, it is possible to achieve barrier-free by reducing the thickness of the eaves portion of the lid member.

  In addition, the base member is fixed to the sill in advance, and after the finishing material is applied, the insertion part of the lid member is inserted into the receiving port of the base member and engaged, so the base member and the lid member are integrated. Compared to the construction, it was easier and the fit was better.

  Further, in the case where the upper end side of the insertion portion opposite to the eave portion of the lid member is protruded outward to form a protruding portion, the protruding portion abuts the sill, and the lower portion of the inserting portion Since there is a slight gap between the sill and the sill, it is possible to absorb deformation due to the humidity change of the sill. Furthermore, by forming the base member and the lid member from a foam-molded product in which wood powder and a foaming agent are mixed in an ASA resin, it is possible to manufacture the threshold parting at low cost. Furthermore, if the thermoplastic elastomer that forms the adhesion part is selected from styrene, olefin, diolefin, and urethane, it is inexpensive, has excellent rubber elasticity, and adheres to the wood finish. The property is also good. Furthermore, by integrally molding the lid member and the close contact portion by the two-color molding method, both members can be firmly integrated, and the manufacturing cost can be reduced. Furthermore, at least one groove along the longitudinal direction is formed in the side surface of the insertion portion of the base member on the eaves portion extending side, and a fastener such as a nail is driven into the sill from this groove. As a result, workability is improved.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  In the embodiment shown in FIG. 1, a wood-type sill 3 is provided on a floor base 2, and a room in which a tatami 4 is laid on one side across the sill 3 is configured, and the other is a wood-based finishing material 5. Other rooms or hallways made up of are formed. A wooden base material 6 such as a particle board is provided below the wooden finishing material 5. A sill part 1 is provided between the wood-based sill 3 and the wooden finish 5. This sill part 1 is attached to the side surface of the sill 3 by a fastener 7 such as a nail.

  As shown in FIG. 2, the threshold closing 1 includes a lid member 10 including an insertion portion 11 and an eaves portion 12 extending from the upper end of the insertion portion 11 to cover one end side surface of the wood-based finishing material 5. The close contact part 13 formed from a soft thermoplastic elastomer is provided along the longitudinal direction on the lower surface of the eaves part 12 of the cover member 10. As shown in FIG. 1, the close contact portion 13 is provided so as to be in close contact with the one end side surface of the wood-based finishing material 5. Moreover, the threshold part 1 consists of what combined this cover member 10 and the base member 20, and the base member 20 has the receiving port 21 in the upper end side, as shown in FIG. The insertion portion 11 is inserted and engaged. The fastener 7 is driven into a portion below the receiving port 21 of the base member 20. The receiving port 21 is formed in an upper end portion 21A having a U-shaped cross section, and the fastening tool 7 is driven into a lower end portion 21B extending from one side surface of the upper end portion 21A. In addition, as shown in FIG. 4, an uneven shape a is formed on both surfaces of the insertion portion 11, and an uneven shape b that fits with the uneven shape a is formed on the inner surface of the receiving port 21. When inserting the insertion portion 11 into the receiving port 21, the insertion portion 11 can be inserted while the left and right walls of FIG. 2 of the upper end portion 21A are opened.

  The lid member 10 and the base member 20 can be suitably formed from a synthetic resin material mixed with wood powder. Further, the protruding portion 14 is formed by projecting the upper end side of the insertion portion 11 opposite to the eaves portion 12 of the lid member 10 outward. In this embodiment, the protruding portion 14 protrudes 0.5 mm from the back surface of the base member 20. The dimensions of each part of the threshold closing 1 are as shown in FIG. 2, and the unit of the numerical values shown in FIG. 2 is mm. Furthermore, a groove 15 is formed along one longitudinal direction on the side surface of the lower end portion 21B of the base member 20, and a fastening tool 7 such as a nail is driven into the sill 3 from these grooves 15. Yes.

  The thermoplastic elastomer (TPE) that forms the contact portion 13 is a polymer material that exhibits the properties of vulcanized rubber at room temperature, but can be plastically deformed at high temperatures and can be molded with a plastic processing machine, It has an intermediate property between rubber and plastic. Of these materials called TPE, it is desirable to use any of styrene, olefin, diolefin, urethane, ester, amide, and fluorine other than vinyl chloride. Halogen-based additives are not used. This is because the halogen compound is concerned about adverse environmental effects. There are three types of styrene-based TPE, SBS, SIS, and SEBS, which have properties closest to vulcanized rubber, and are therefore suitable as a material for forming the adhesion portion 13. Olefin-based TPE has the lightest specific gravity, and urethane-based TPE is excellent in wear resistance and flex resistance. In addition, ester-based TPE is excellent in mechanical strength, but it is difficult to obtain a flexible product. Amide-based TPE is excellent in toughness, but has poor rubber elasticity, and fluorine-based TPE is excellent in many physical properties but is the most expensive. Therefore, TPE suitable as a material for forming the contact portion 13 is styrene, olefin, diolefin, or urethane.

  As the synthetic wood forming the lid member 10 and the base member 20, one obtained by extruding ASA resin (acrylonitrile / styrene / acrylate) pellets in which wood powder and a foaming agent are mixed can be suitably used. The ASA resin is an acrylic rubber type, and the weather resistance is greatly improved as compared with the butadiene rubber. As the thermoplastic resin material, polypropylene and polyethylene can be used in addition to the ASA resin. By using the lid member 10 and the base member 20 that are formed of a synthetic resin material mixed with wood powder, even if it is provided between the wood-based sill 3 and the wood-based finishing material 5, there is no sense of discomfort. Moreover, although the extension length of the eaves portion 12 is 11.5 mm, it is of course possible to make it longer in consideration of the maximum value such as expansion and contraction due to the humidity change of the wood-based finishing material 5. Further, the formation of the protruding portion 14 can sufficiently cope with the deformation of the wooden sill 3 due to the humidity change. Further, the thickness of the eaves portion 12 tends to be thin (3 mm or less) because of the requirement for barrier-free, and thus in this embodiment, the thickness was set to 2.0 mm. Further, the corner portion of the eaves portion 12 is chamfered.

  When the lid member 10 is molded from a synthetic resin material, it is preferable that the contact portion 13 is also molded at the same time, that is, two-color molding is performed to integrally mold both. By molding by a two-color molding method which is a special extrusion molding, the contact portion 13 and the lid member 10 are firmly integrated, and there is no possibility that the contact portion 13 is peeled off from the lid member 10.
