Description

[Technical field]

[0001] The present invention relates to a floor trim material. [Background technology]

[0002] The floor trim is configured, for example, to be installed at the butt joint of adjacent floor materials of different types so as to make the ends of the adjacent floor materials look attractive.

[0003] For example, Patent Document 1 discloses a floor trim that is made up of a support material having a pair of protruding pieces and a trim material having a pair of grooves. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4096699 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the floor trim disclosed in the above Patent Document 1, the thickness of the floor material on which the floor trim is installed is fixed, which means that it has little versatility and there is room for improvement.

[0006] The present invention has been made in consideration of the above-mentioned points, and an object of the present invention is to provide a floor trim material with high versatility. [Means for solving the problem]

[0007] In order to achieve the above object, the floor trim material of the present invention is a floor trim material having a surface portion provided in a band shape and a leg portion provided in a band shape so as to protrude downward from a middle portion in the width direction of the lower surface of the surface portion, and one side surface along the length direction of the leg portion has one or more grooves provided along the length direction at a middle portion in the height direction. The portion of the leg where the groove is provided is made of soft resin, and the portion of the leg other than the portion where the groove is provided and the surface portion are made of hard resin, and the leg is provided so as to be bent at one of the grooves depending on the thickness of the flooring material to be used. It is characterized by the fact that

[0008] According to the above configuration, the legs are provided in a strip shape so as to protrude downward from the middle part in the width direction of the lower surface of the strip-shaped surface part, and one or more grooves are provided along the length direction at the middle part in the height direction of one side surface along the length direction of the legs, so that two types of modes can be taken: a mode in which the legs are not bent or cut at the grooves, and a mode in which the legs are bent or cut at the grooves. Furthermore, when multiple grooves are provided, there are multiple types of modes in which the legs are bent or cut at the grooves according to the number of grooves. This allows the height of the legs to be adjusted according to the thickness of the flooring material, so that a floor trim material with high versatility can be provided. Also, Since the portion of the leg where the groove is provided is made of soft resin, the leg can be easily bent or cut at the groove. Also, Since the legs are provided so as to be bent at the grooves according to the thickness of the flooring material used, the height of the legs can be adjusted to match the thickness of the flooring material, and even if the tip parts of the legs become unnecessary in order to adjust the height of the legs, the tips of the legs are simply bent at the grooves, so that the tip parts of the legs are not discharged as waste.

[0009] In addition, the floor trim material of the present invention is a floor trim material having a surface portion arranged in a band shape and a leg portion arranged in a band shape so as to protrude downward from a middle portion in the width direction of the underside of the surface portion, and is characterized in that one side surface along the length of the leg has one or more grooves arranged along the length at the middle portion in the height direction, the portion of the leg where the grooves are arranged is formed from a soft resin, the portion of the leg other than the portion where the grooves are arranged and the surface portion are formed from a hard resin, and the leg is arranged so as to be cut at one of the grooves depending on the thickness of the floor material to be used.

[0010] According to the above configuration, the legs are provided in a strip shape so as to protrude downward from the middle part in the width direction of the lower surface of the strip-shaped surface part, and one or more grooves are provided along the length direction at the middle part in the height direction of one side surface along the length direction of the legs, so that two types of modes can be taken: a mode in which the legs are not bent or cut at the grooves, and a mode in which the legs are bent or cut at the grooves. Furthermore, when multiple grooves are provided, the mode in which the legs are bent or cut at the grooves is multiple types according to the number of grooves. This allows the height of the legs to be adjusted to match the thickness of the flooring material, so that a floor trimming material with high versatility can be provided. In addition, since the part of the legs where the grooves are provided is formed of soft resin, the legs can be easily bent or cut at the grooves. In addition, since the legs are provided so as to be cut at the grooves according to the thickness of the flooring material to be used, the height of the legs can be adjusted to match the thickness of the flooring material, and even if the tip part of the legs becomes unnecessary in order to adjust the height of the legs, the tip part is cut and removed, so that the size of the legs in the width direction can be maintained.

[0011] The leg portion may be provided such that, when the groove is bent into a U-shape so that the groove faces outward, the tip of the leg portion can come into contact with the underside of the surface portion.

[0012] According to the above configuration, for example, the length from the center of the groove (bottom of the groove) to the tip of the leg is slightly longer than the length from the center of the groove (bottom of the groove) to the underside of the surface portion, so that the tip of the leg can contact the underside of the surface portion when the leg is bent into a U shape at the groove. As a result, when the leg is bent into a U shape at the groove, the tip of the leg can be caught on the underside of the surface portion, and the tip of the leg can be easily fixed. 。

[0013] above On the other side surface along the length of the leg portion, another groove may be provided along the length in a middle portion in the height direction in correspondence with the above groove.

[0014] According to the above configuration, the groove and the other groove are provided along the length of the leg at the middle of the height direction on one side and the other side along the length of the leg, respectively, and the cross-sectional shape is line-symmetrical, so that warping during molding is suppressed and the floor trim can be easily manufactured by extrusion molding. Also, since the groove and the other groove are arranged back-to-back on the leg, the leg can be cut at the groove more easily. Effect of the Invention

[0015] According to the present invention, one or more grooves are provided along the length of the middle part in the height direction of one side of the leg that runs along the length of the floor trim material, thereby providing a floor trim material with high versatility.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiments.

[0018] First Embodiment Fig. 1 to Fig. 6 show a first embodiment of a floor trim material and a floor structure including the same according to the present invention. Here, Fig. 1 is a perspective view of a floor trim material 10a of this embodiment. Also, Fig. 2 is a front view of a floor trim material 10b as a modified example of the floor trim material 10a. Also, Fig. 3 is a cross-sectional view of a floor structure 50a including the floor trim material 10a. Also, Fig. 4, Fig. 5, and Fig. 6 are cross-sectional views of floor structures 50b, 50c, and 50d as first, second, and third modified examples of the floor structure 50a.

[0019] As shown in Figure 1, the floor trim material 10a has a surface portion 1 arranged in a band shape extending in the longitudinal direction Y, and leg portions 2a arranged in a band shape protruding downward from the middle portion in the width direction X of the underside of the surface portion 1, and has an approximately T-shaped cross section.

[0020] As shown in Fig. 1, the surface portion 1 has a cross section of a substantially isosceles trapezoid whose lower base is longer than its upper base. Here, a double-sided adhesive tape having a release paper removably provided on the surface may be attached to the lower surface of the surface portion 1. The surface portion 1 is formed of a hard resin such as ABS (acrylonitrile-butadiene-styrene) resin.

[0021] As shown in FIG. 1, on one side (left side in the figure) of the leg 2a along the length direction Y, a plurality of (for example, two) V-shaped grooves C are provided along the length direction Y in the middle part of the height direction Z. Here, in the leg 2a, the groove C on the surface part 1 side (upper side in FIG. 1) is provided at a position 3 / 4 from the bottom of the height direction Z of the leg 2a, and the groove C on the tip side (lower side in FIG. 1) is provided at a position 1 / 2 of the height direction Z of the leg 2a. As a result, for example, in the leg 2a of the floor trim 10a for flooring with a thickness of 12 mm, by cutting or bending the leg 2a at the upper groove C in FIG. 1, it can be adapted to a flooring with a thickness of 3 mm, and by cutting or bending the leg 2a at the lower groove C in FIG. 1, it can be adapted to a flooring with a thickness of 6 mm. As shown in FIG. 1, the leg 2a has a soft portion S formed of a soft resin having a groove C, and a hard portion formed of the hard resin other than the soft portion S. As the soft material, vinyl chloride, styrene elastomer, etc. are preferably used, but various resins can be used as long as they are soft resins that can be elastically deformed. As the soft material, for example, butyl rubber, silicone rubber, chloroprene rubber, etc. can also be used, but elastomer-based resins or vinyl chloride-based resins are most preferably used when long-term use is assumed. The soft portion S may be provided at each bottom, centered on the bottom of the groove C, like the floor trim material 10b described later.

[0022] As shown in Fig. 2, floor trim 10b, which is a modified version of floor trim 10a, has a band-shaped surface 1 and a band-shaped leg 2b protruding downward from the middle part in the width direction of the lower surface of surface 1, and has a substantially T-shaped cross section. Note that floor trim 10b has a configuration in which the height of leg 2a of floor trim 10a described above is reduced and the number of grooves C is changed.

[0023] As shown in FIG. 2, one side surface (left side surface in the figure) along the length of the leg 2b has a V-shaped groove C in cross section along the length at the middle part in the height direction. Here, the length from the bottom of the groove C to its tip is designed to be slightly longer than the length from the bottom of the groove C to the underside of the surface part 1, so that the tip of the leg 2b can contact the underside of the surface part 1 when the leg 2b is bent into a U shape at the groove C so that the groove C faces outward. As a result, when the leg 2b is bent into a U shape at the groove C, the tip of the leg 2b is hooked on the underside of the surface part 1, so that the tip of the leg 2b can be easily fixed. Specifically, for example, in the leg 2b of the floor trim material 10b for flooring materials with a thickness of 6 mm, the length from the bottom of the groove C to its tip is 2.75 mm, and the length from the bottom of the groove C to the underside of the surface part 1 is 2.7 mm. Leg 2b can be adapted to a floor material with a thickness of 3 mm by cutting or bending leg 2b at groove C. As shown in Fig. 2, leg 2b has soft portion S made of soft resin where the bottom of groove C is provided, and hard portion other than soft portion S made of hard resin.

[0024] The above-mentioned floor trim material 10a (10b) can be manufactured, for example, by extrusion molding in which hard resin and soft resin are simultaneously extruded through separate dies to form the material.

[0025] Moreover, the above-mentioned floor trim material 10a (10b) is provided between a first floor material and a second floor material adjacent to each other, as described later, and constitutes floor structures 50a, 50b, 50c, and 50d.

Here, the first flooring material 20c has a male seed Ja on the side of the second flooring material 30c side as shown in Fig. 5. Also, the second flooring material 30c has a female seed Jb on the side of the first flooring material 20c side as shown in Fig. 5 so as to fit with the male seed Ja of the first flooring material 20c.

[0034] The floor trim 10ab is composed of the floor trim 10a described above, and in the floor structure 50c, as shown in FIG. 5, the leg 2a (see FIG. 1) is provided so as to be bent in a U-shape at the groove C on the tip side on the upper side of the male joint Ja. The surface portion 1 of the floor trim 10ab is fixed to the upper surface end of each of the first floor material 20c and the second floor material 30c by, for example, a double-sided adhesive tape attached to its underside. In addition, in this embodiment, the configuration in which the leg 2a is bent at the groove C on the tip side is exemplified, but the leg 2a may be cut at the groove C on the tip side, and the tip side of the leg 2a may be the broken portion B.

[0035] As shown in FIG. 6, the floor structure 50d comprises a first floor material 20d and a second floor material 30d arranged adjacent to each other, and a floor trim material 10ab arranged between the first floor material 20d and the second floor material 30d, with the surface portion 1 (see FIG. 1) of the floor trim material 10ab being arranged so as to abut against the upper surfaces of the first floor material 20d and the second floor material 30d, and the leg portion 2a (see FIG. 1) of the floor trim material 10ab being arranged so as to be positioned between the first floor material 20d and the second floor material 30d.

[0036] The first flooring material 20d and the second flooring material 30d are formed to a thickness of about 6 mm, and include a wooden base material made of MDF or the like and a surface decorative layer made of a resin film or the like provided on the wooden base material. Here, female insemination Jb is provided on the side surface of the first flooring material 20d facing the second flooring material 30d and on the side surface of the second flooring material 30d facing the first flooring material 20d, as shown in FIG.

[0037] The floor trim 10ab is composed of the floor trim 10a described above, and in the floor structure 50d, as shown in FIG. 6, the leg 2a (see FIG. 1) is provided so as to be bent in a U-shape at the groove C on the tip side. The surface portion 1 of the floor trim 10ab is fixed to the upper surface end of each of the first floor material 20d and the second floor material 30d by, for example, a double-sided adhesive tape attached to its underside. In addition, in this embodiment, the configuration in which the leg 2a is bent at the groove C on the tip side is exemplified, but the leg 2a may be cut at the groove C on the tip side, and the tip side of the leg 2a may be the broken portion B.

[0038] As described above, according to the floor trim 10a of this embodiment, the leg 2a is provided in a strip shape so as to protrude downward from the middle part in the width direction of the lower surface of the strip-shaped surface portion 1, and two grooves C are provided along the length direction at the middle part in the height direction of one side surface along the length direction of the leg 2a, so that three types of modes can be taken: a mode in which the leg 2a is not bent or cut (for example, corresponding to a floor material with a thickness of about 12 mm) and two modes in which the leg 2a is bent or cut at one of the two grooves C (for example, corresponding to a floor material with a thickness of about 3 mm or about 6 mm). As a result, the height of the leg 2a can be adjusted according to the thickness of the floor material, so that the floor trim 10a with high versatility can be provided.

[0039] In addition, according to the floor trim 10b of this embodiment, the legs 2b are provided in a strip shape so as to protrude downward from the middle part in the width direction of the lower surface of the strip-shaped surface portion 1, and one groove C is provided along the length direction at the middle part in the height direction of one side surface along the length direction of the legs 2b, so that two types of modes can be taken: a mode in which the legs 2b are not bent or cut (for example, corresponding to a floor material with a thickness of about 6 mm) and a mode in which the legs 2b are bent or cut at the groove C (for example, corresponding to a floor material with a thickness of about 3 mm to 5 mm). As a result, the height of the legs 2b can be adjusted according to the thickness of the floor material, so that the floor trim 10b with high versatility can be provided.

[0040] In addition, according to the floor trim materials 10a and 10b of this embodiment, at least the portions of the legs 2a and 2b where the grooves C are provided are formed from soft resin, so that the legs 2a and 2b can be easily bent or cut at the grooves C.

[0041] Furthermore, according to the floor trim 10b of this embodiment, the length from the center (bottom of the groove) of the groove C to the tip of the leg 2b is made slightly longer than the length from the center (bottom of the groove) of the groove to the underside of the surface portion 1, so that the tip of the leg 2b can come into contact with the underside of the surface portion 1 when the leg 2b is bent into a U shape at the groove C. As a result, when the leg 2b is bent into a U shape at the groove C, the tip of the leg 2b gets caught on the underside of the surface portion 1, and the tip of the leg 2b can be easily fixed.

[0042] In addition, according to the floor structure 50a (50b, 50c, 50d) of this embodiment, when the leg portion 2a of the floor trimming material 10a is arranged between the first floor material 20a (20b, 20c, 20d) and the second floor material 30a (30b, 30c, 30d) adjacent to each other, the surface portion 1 of the floor trimming material 10a abuts on the upper surfaces of the first floor material 20a (20b, 20c, 20d) and the second floor material 30a (30b, 30c, 30d).

[0043] In addition, according to the floor structure 50a of this embodiment, the legs 2a of the floor trim material 10a are arranged so as not to bend at each groove C, and adhesive 5 is provided inside each groove C, so that the floor trim material 10a can be installed between the first floor material 20a and the second floor material 30a, which have a thickness equal to or greater than the height of the legs 2a when not bent at each groove C, and it is possible to make it difficult for the legs 2a of the floor trim material 10a to slip out from between the first floor material 20a and the second floor material 30a.

[0044] In addition, according to the floor structure 50b of this embodiment, the leg 2a of the floor trim material 10a is arranged to bend into a U-shape at the groove C at the tip side, so that the floor trim material 10a can be installed between the first floor material 20b and the second floor material 30b, which have a thickness approximately equal to or greater than the height of the leg 2a when bent at the groove C.

[0045] In addition, according to the floor structure 50c of this embodiment, the first floor material 20c has a male stump Ja on the side facing the second floor material 30c, and the second floor material 30c has a female stump Jb on the side facing the first floor material 20c, so that the first floor material 20c and the second floor material 30c adjacent to each other are connected via the male stump Ja and the female stump Jb. The floor trim 10a installed between the first floor material 20c and the second floor material 30c has its leg 2a bent in a U-shape at the tip side groove C above the male stump Ja, so that the floor trim 10a can be installed even between the first floor material 20c and the second floor material 20c connected via the male stump Ja and the female stump Jb.

[0046] Furthermore, according to the floor structure 50d of this embodiment, the leg 2a of the floor trim material 10a is arranged to bend into a U-shape at the groove C at the tip side, so that the floor trim material 10a can be installed between the first floor material 20d and the second floor material 30d, which have a thickness approximately equal to or greater than the height of the leg 2a when bent at the groove C.

[0070] In addition, according to the floor structure 60e of this embodiment, a floor material 20i is arranged on the other side side where the grooves C of the leg 2a of the floor trim material 10ac are not provided, a female joint Jb is provided on the side surface of the floor material 20i facing the wall material W, and the leg 2a of the floor trim material 10ac is arranged so that the tip side of the leg 2a is bent while inserted into the female joint Jb, so that the floor trim material 10ac (10a) can be installed between the floor material 20i and the wall material W with the tip side of the leg 2a bent by the groove C on the tip side contained within the female joint Jb of the floor material 20i.

[0071] Third embodiment Fig. 12 to Fig. 14 show a third embodiment of the floor trim material and a floor structure including the same according to the present invention. Here, Fig. 12 is a front view of the floor trim material 10c of this embodiment. Also, Fig. 13 is a cross-sectional view of a floor structure 50e including the floor trim material 10c. Also, Fig. 14 is a cross-sectional view of a floor structure 50f which is a modified example of the floor structure 50e.

[0072] In each of the above embodiments, a floor trim material 10a (10b) having a groove C on one side along the longitudinal direction of the leg 2a (2b) and a floor structure including the same are exemplified, whereas in the present embodiment, a floor trim material 10c having a groove C on one side and the other side along the longitudinal direction of the leg 2c and a floor structure 50e (50f) including the same are exemplified.

[0073] As shown in Fig. 12, the floor trim 10c has a surface portion 1 provided in a strip shape and a leg portion 2c provided in a strip shape so as to protrude downward from a middle portion in the width direction of the lower surface of the surface portion 1, and has a substantially T-shaped cross section.

[0074] As shown in FIG. 12, one side and the other side along the length of the leg 2c are provided with a U-shaped groove C in cross section and another groove C along the length at the middle part in the height direction Z. Here, in the leg 2c, each groove C is provided at a position halfway along the height direction of the leg 2c as shown in FIG. 12. As a result, as described later, in the leg 2c of the floor trimming material 10c for flooring with a thickness of 12 mm, the leg 2c can be cut at the groove C to accommodate flooring with a thickness of 6 mm. Also, as shown in FIG. 12, the leg 2c has a soft part S formed of a soft resin provided with the groove C, and a hard part formed of a hard resin other than the soft part S. Here, in the soft part S, a protruding part P protruding laterally is provided on the surface part 1 side of each groove C along the length. In FIG. 12, the boundary between the soft part S and the hard part is indicated by a dashed line.

[0075] The above-mentioned floor trim material 10c can be manufactured, for example, by extrusion molding in which hard resin and soft resin are simultaneously extruded through separate dies.

[0076] Moreover, the above-mentioned floor trim material 10c is provided between adjacent first and second floor materials, as described below, to form floor structures 50e and 50f.

[0077] Specifically, as shown in Figure 13, the floor structure 50e comprises a first floor material 20a and a second floor material 30a arranged adjacent to each other with a thickness of approximately 12 mm, and a floor trim material 10ca arranged between the first floor material 20a and the second floor material 30a, with the surface portion 1 (see Figure 12) of the floor trim material 10ca being arranged so as to abut against the upper surfaces of the first floor material 20a and the second floor material 30a, and the leg portion 2c (see Figure 12) of the floor trim material 10ca being arranged so as to be positioned between the first floor material 20a and the second floor material 30a.

[0078] The floor trim 10ca is composed of the above-mentioned floor trim 10c, and in the floor structure 50e, as shown in FIG. 13, the leg 2c (see FIG. 12) is arranged so as not to bend at the groove C. Here, each protrusion P (see FIG. 12) of the leg 2c is deformed so as to bend at its base as shown in FIG. 13. The surface portion 1 of the floor trim 10ca is fixed to the upper end of each of the first floor material 20a and the second floor material 30a, for example, by a double-sided adhesive tape attached to its underside. The leg 2c of the floor trim 10ca may also be fixed to each side of the first floor material 20a and the second floor material 30a, for example, by applying an adhesive to its surface.

[0079] As shown in FIG. 14, the floor structure 50f comprises a first floor material 20b and a second floor material 30b arranged adjacent to each other with a thickness of approximately 6 mm, and a floor trim material 10cb arranged between the first floor material 20b and the second floor material 30b, with the surface portion 1 (see FIG. 12) of the floor trim material 10cb being arranged so as to abut against the upper surfaces of the first floor material 20b and the second floor material 30b, and the leg portion 2c (see FIG. 12) of the floor trim material 10cb being arranged so as to be positioned between the first floor material 20b and the second floor material 30b.

[0080] The floor trim 10cb is composed of the above-mentioned floor trim 10c, and in the floor structure 50f, as shown in FIG. 14, the leg 2c (see FIG. 12) is cut at the groove C by, for example, using a cutter knife or by tearing by hand, and has a broken portion B. Here, each protrusion P (see FIG. 12) of the leg 2c is deformed so as to bend at its base, as shown in FIG. 14. The surface portion 1 of the floor trim 10cb is fixed to each upper end of the first floor material 20b and the second floor material 30b, for example, by double-sided adhesive tape attached to its underside. The leg 2c of the floor trim 10cb may also be fixed to each side of the first floor material 20b and the second floor material 30b, for example, by applying an adhesive to its surface.

[0081] In this embodiment, a floor structure 50e (50f) in which a floor trim material 10c is arranged between adjacent first and second floor materials is exemplified, but as in the second embodiment above, the floor trim material 10c may be arranged between adjacent floor and wall materials.

[0082] As described above, according to the floor trim 10c of this embodiment, the legs 2c are provided in a strip shape so as to protrude downward from the middle part in the width direction of the lower surface of the strip-shaped surface portion 1, and one groove C is provided along the length direction at the middle part in the height direction of one side surface and the other side surface of the legs 2c along the length direction, so that two types of modes can be taken: a mode in which the legs 2c are not cut (for example, corresponding to a floor material with a thickness of about 12 mm) and a mode in which the legs 2c are cut at the groove C (for example, corresponding to a floor material with a thickness of about 6 mm). As a result, the height of the legs 2c can be adjusted according to the thickness of the floor material, so that the floor trim 10c with high versatility can be provided.

[0083] Furthermore, according to the floor trim 10c of this embodiment, at least the portion of the leg 2c on which the groove C is provided is made of soft resin, so that the leg 2c can be easily cut at the groove C.

[0084] In addition, according to the floor trim 10c of this embodiment, the groove C and the other groove C are provided along the length of the leg 2c at the middle of the height direction on one side and the other side along the length of the leg 2c, respectively, and the cross-sectional shape is line symmetrical, so that warping during molding is suppressed and the floor trim 10c can be easily manufactured by extrusion molding. In addition, since the groove C and the other groove C are arranged back to back on the leg 2c, the leg 2c can be cut at the groove C more easily.

[0085] In addition, according to the floor structure 50e (50f) equipped with the floor trim 10c of this embodiment, the leg 2c of the floor trim 10c is arranged between the adjacent first floor material 20a (20b) and second floor material 30a (30b), and the surface portion 1 of the floor trim 10c abuts the upper surfaces of the first floor material 20a (20b) and the second floor material 30a (30b). Therefore, by attaching the lower surface of the surface portion 1 of the floor trim 10c to the end of the upper surface of the first floor material 20a (20b) on the second floor material 30a (30b) side and the end of the upper surface of the second floor material 30a (30b) on the first floor material 20a (20b) side, a floor structure 50e (50f) can be constructed in which the floor trim 10c is fixedly installed between the adjacent first floor material 20a (20b) and second floor material 30a (30b).

[0086] Other Embodiments In each of the above embodiments, a floor trim material having a surface portion and leg portions and an approximately T-shaped cross-section has been exemplified, but for example, in the case of a floor trim material to be installed between a floor material and a wall material, it may be a floor trim material having one side of the width direction of the surface portion cut to have an approximately L-shaped cross-section.
