By the way, such an L-type decorative material is desired to have a decorative sheet stuck to the surface of the base material, which does not easily peel off or float, and in which the strength of the bent portion is ensured.
For example, when an L-type cosmetic material is used as an eaves for an entrance, if there is a small peeling at the edge of the decorative sheet and there is a catch, a person or luggage that goes up and down touches the catch, and the decorative sheet is peeled off from there. There is a fear. Further, for example, when the thickness of the top surface portion of the L-type decorative material is reduced in accordance with the thickness of the flooring material, the strength of the bent portion of the L-type decorative material may be weakened.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an L-type decorative material in which a decorative sheet is difficult to peel off and the strength of a bent portion can be secured.

  In order to achieve the above object, the L-type decorative material according to the present invention is obtained by bending a base material having a decorative sheet attached to the entire surface at a bent portion so that the surface side is mountain-folded. An L-shaped decorative material formed in an L-shaped cross section having a portion, wherein the top surface portion is formed in a thin shape at one end thereof and folded back to the back side so that the thin portions overlap each other. A first folded portion having the same thickness as the thickness of the base material is formed, and the side surface portion is folded thicker than the thickness of the base material by overlapping one end portion thereof on the back side. Two folded portions are formed.

  In the present invention, the back surface of the side surface portion is arranged so as to be in contact with the back surface, and one end surface is in contact with the end surface of the base material folded at the second folded portion. The top surface may be provided with a concave groove in which the other end surface of the spacer is locked.

  Since the L-type decorative material according to the present invention is configured as described above, the decorative sheet is difficult to peel off and the strength of the bent portion can be ensured.

In the L-type decorative material 1 according to the present embodiment, the base 3 with the decorative sheet 2 attached to the entire surface 3a is bent at the bent portion 6 so that the surface 3a side is mountain-folded, and the top surface portion 4 and the side surface portion. 5 is formed in an L-shaped cross section. The top surface portion 4 is formed with a first folded portion 40 having one end portion formed in a thin shape and folded back toward the back surface 3b so that the thin portions overlap each other to have the same thickness as the thickness t1 of the substrate 3. Has been. The side surface portion 5 is formed with a second folded portion 50 that is thicker than the plate thickness t1 of the base material 3 by folding one end of the side surface portion 5 toward the back surface 3b. This will be described in detail below.
In addition, the code | symbol in a figure has the location which abbreviate | omitted suitably, the decorative sheet 2 is shown with the dashed-two dotted line in Fig.1 (a), and illustration of the decorative sheet 2 is abbreviate | omitted in FIG.1 (b).

The L-type decorative material 1 is L-shaped in a cross-sectional view as shown in FIG. 1 (a), and can be used, for example, as a rising ridge such as a front door or a convenient door. It is constructed on the top of the floor and on the flooring.
The base material 3 includes wood-based materials such as plywood and LVL (single-plate laminate), wood boards such as particle boards, and wood fiber boards such as insulation boards and MDF (medium density fiber boards). In addition to being used, it may be a solid material. The base material 3 may be formed of a wood powder / plastic composite material (WPC) in which a synthetic resin material, an inorganic filler, a compatibilizing agent, a colorant and the like are contained in wood powder in a predetermined content ratio. Good. Furthermore, the base material 3 may have a multilayer structure in which plate materials made of these various materials are laminated.

  The decorative sheet 2 attached to the surface 3a of the base material 3 is a thin sheet having flexibility that can withstand bending of the base material 3, and may be provided with a pattern such as a wood grain pattern. For example, a synthetic resin sheet such as polyethylene, polypropylene, polyvinyl chloride, or polyethylene terephthalate may be employed. Further, the decorative sheet 2 may be antibacterial or antislip coated. In the figure, reference numeral 2 a denotes an end of the decorative sheet 2.

  The base material 3 is formed in a substantially rectangular flat plate shape as shown in FIG. 2 before being bent into an L shape at the bent portion 6, and the thickness t1 is not particularly limited, but is, for example, 6.5 mm to 8 mm. The degree is desirable, and the thickness may be set to the same level as a flooring (not shown) laid side by side with the L-shaped decorative material 1. A decorative sheet 2 is adhered to the entire surface 3a of the substrate 3 from end to end of the substrate 3 (see FIG. 2). A plurality of grooves having a substantially V-shaped cross section are formed on the back surface 3b of the base material 3 in order to bend the base material 3 made of a wood-based material or the like. Specifically, at the center position of the back surface 3b of the base material 3, two grooves having a substantially V-shaped cross section for forming the bent portion 6 are cut in parallel with a predetermined width dimension. And when the part (triangular convex part 60) which remained in the cross-sectional triangle shape between two groove | channels bends the base material 3 in the bending part 6 so that the surface 3a may become a mountain fold, FIG. A chamfered shape with a rounded corner is formed as shown in a). And one side is made into the top | upper surface part 4 and the other is made into the side part 5 across the bending part 6 of the base material 3. FIG. The bent portion 6 is provided with a space for receiving the inner end 42 on the bent portion 6 side of the top surface portion 4 when the base material 3 is bent in an L shape. A concave step portion 6a is formed so that the portions fit (see FIGS. 1A and 2). In the vicinity of the inner end portion 42 of the top surface portion 4, a concave groove 41 is formed in which the spacer 7 arranged so as to be in contact with the back surface 5 a of the side surface portion 5 is engaged. The concave groove 41 is formed so that a slight gap is provided when the end surface 71 of the spacer 7 is locked as shown in FIG.

A first folded portion 40 is formed at one end portion of the top surface portion 4 of the base material 3, and the first folded portion 40 has a triangular convex portion 43, a front plate portion 45, and a back plate portion 44. And a step wall portion 40a. The first folded portion 40 is configured as the top surface portion 4 in a state in which the back plate portion 44 of the first folded portion 40 is folded back to the back surface 3b side, and the back plate portion 44 and the front plate portion 45 are overlapped. The material 3 is formed to have the same thickness as the thickness t1 (see FIG. 1A). Therefore, one end portion on the top surface portion 4 side of the base material 3 is cut until the thickness becomes half of the plate thickness t1 of the base material 3, and the thin end portion has a central position along the longitudinal direction. Two grooves having a substantially V-shaped cross section are cut in parallel, and a portion remaining in a triangular cross section is a triangular convex portion 43 between the two grooves, and the bent portion 6 sandwiches the triangular convex portion 43. The side is a front surface plate-like portion 45, and the opposite side is a back surface plate-like portion 44. The angle of the inclined surfaces of the two grooves and the angle of the apex of the triangular protrusion 43 (the apex protruding from the decorative sheet 2) are both right angles (that is, 90 °). Thereby, if the one end part of the top surface part 4 of the base material 3 is folded back to the back surface 3b side, it can be set as the plate-shaped top surface part 4 which has a substantially right angle | corner part, and the end surface by the side of the top surface part 4 of the base material 3 30 will be in the state faced | matched with the step wall part 40a formed by cutting thinly (refer Fig.1 (a)). In the state where the first folded portion 40 is folded, the front surface plate-like portion 45 constitutes a part of the surface of the top surface portion 4, and the back surface plate-like portion 44 constitutes a part of the back surface of the top surface portion 4. As shown in FIG. 2, the plate thickness t3 before the first folded portion 40 is folded is half as thin as the plate thickness t1 of the base material 3. Therefore, in the state after the first folded portion 40 is folded, The face plate portion 44 is in a state where it is accommodated in the step space, and the back surface of the top surface portion 4 and the back surface plate portion 44 are flush with each other as shown in FIG. Further, the front plate portion 45 and the back plate portion 44, which are half as thin as the plate thickness t1 of the substrate 3, overlap each other, and the plate thickness of the first folded portion 40 is the same as the plate thickness t1 of the substrate 3. The thickness is t1. Therefore, for example, if the plate thickness t1 of the base material 3 is set to be the same as the plate thickness of the floor material of the indoor floor, the top surface portion 4, the plate thickness, and the plate thickness of the floor material may be the same. it can.
Since the decorative sheet 2 is adhered to the entire surface of the base material 3 as described above, the decorative sheet 2 is also adhered to the surface of the back plate portion 44.
In addition, the one end part by the side of the top | upper surface part 4 of the base material 3 was not restricted to what was cut by the half thickness of the board thickness t1 of the base material 3, but the front surface plate-shaped part 45 and the back surface plate-shaped part 44 were piled up. At this time, if the thickness is equal to the thickness t1 of the base material 3, the thicknesses of the front plate portion 45 and the back plate portion 44 are not necessarily the same.

A second folded portion 50 is formed at one end of the side surface portion 5 of the substrate 3, and the second folded portion 50 has a triangular convex portion 51 and a back plate-like portion 52. The second folded portion 50 is formed to be thicker than the plate thickness t <b> 1 of the base material 3 by folding the back surface plate-like portion 52 of the second folded portion 50 toward the back surface 3 b and overlapping. The second folded portion 50 is formed in consideration of the dimensions configured as the side surface portion 5 in a state in which the base material 3 is folded back by the second folded portion 50, and has a predetermined dimension from the end surface 31 on the side surface portion 5 side of the base material 3. Two grooves having a substantially V-shaped cross section are cut in parallel along the longitudinal direction at a distant place, and a portion remaining in a triangular cross section is formed as a triangular convex portion 51 between the two grooves. A side opposite to the bent portion 6 side (end surface 31 side) with the portion 51 interposed therebetween is a back plate portion 52. Both the angle of the inclined surfaces of the two grooves and the angle of the apex of the triangular convex portion 51 (the apex protruding from the decorative sheet 2) are right angles (that is, 90 °). Thereby, when the one end part of the side part 5 of the base material 3 is turned back to the back surface 3b, it can be set as the plate-shaped side part 5 which has a substantially right-angled corner | angular part, Since they are folded back so as to overlap, the plate thickness t2 of the side surface portion 5 can be set to be twice the plate thickness t1 of the base material 3. Further, as described above, since the decorative sheet 2 is adhered to the entire surface of the substrate 3, the decorative sheet 2 is also adhered to the surface of the back plate-like portion 52.
According to the above, the decorative sheet 2 is adhered to the entire surface 3 a of the base material 3, and the decorative sheet 2 is arranged in a state of being wound on the back surface of the top surface portion 4 and the back surface 5 a of the side surface portion 5. Therefore, the decorative sheet 2 can be prevented from peeling off or floating from the end of the base material 3. Therefore, it is suitable as the L-type decorative material 1 for the lift of the entrance where the person is frequently raised and lowered.

  The back surface 5a of the side surface portion 5 is arranged so as to be in contact with the back surface 5a, and one end surface 70 is brought into contact with the end surface 31 of the base material 3 folded back by the second folded portion 50. Spacers 7 are provided. If the spacer 7 has the same thickness t <b> 1 as the base material 3 and has a rigidity functioning as a reinforcing material for the L-type decorative material 1, the material thereof is a woody material similar to the base material 3. In addition, a plastic material or the like may be used. The spacer 7 is a substantially rectangular flat plate as shown in FIG. 1B, and may have a horizontally long shape like the side surface portion 5 of the base material 3, or may be provided with an appropriate interval. Also good. One end surface 70 of the spacer 7 is brought into contact with the end surface 31 of the base material 3, and the other end surface 71 is engaged with the concave groove 41 of the top surface portion 4. At this time, an adhesive may be applied to one surface of the spacer 7 and adhered to the back surface 5 a of the side surface portion 5.

Thus, if the spacer 7 is arrange | positioned in the side surface part 5 thicker than the top surface part 4, and the concave groove 41 in which the spacer 7 is latched is formed in the top surface part 4 side, the bending part 6 of FIG. It can prevent that intensity | strength becomes weak. In particular, as shown in FIG. 1A, the inner end portion 42 protrudes between the spacer 7 and the triangular convex portion 60 that are arranged in contact with the side surface portion 5 and are engaged with the concave groove 41. Since it exists in a state, the strength of the bent portion 6 can be further reinforced.
The spacer 7 is not separately formed as shown in the figure, but the back plate-like portion 52 can be along the back surface 5 a of the side surface portion 5 so that the back plate-like portion 52 becomes a spacer. It is good also as size. In this case, the end surface 31 on the side surface portion 5 side of the base material 3 is locked in the concave groove 41, and the back surface plate-like portion 52 disposed in contact with the triangular convex portion 60 and the side surface portion 5. The inner end portion 42 is interposed in a protruding state, and the strength of the bent portion 6 can be ensured as described above.

  The configurations and shapes of the L-type decorative material 1, the decorative sheet 2, the base material 3, the bent portion 6, the spacer 7, the first folded portion 40, the second folded portion 50, and the like are not limited to the illustrated examples. . For example, in this embodiment, although the bending part 6 is formed in the position shifted | deviated from the center position of the base material 3, and the side part 5 was formed larger than the top | upper surface part 4, the example is shown, It is not limited to this. . The top surface portion 4 and the side surface portion 5 may have the same size, or the side surface portion 5 may be formed smaller than the top surface portion 4. Are not limited to the illustrated examples. Moreover, although this embodiment demonstrated the example in which the top | upper surface part 4 is provided along with a flooring, it is not limited to this example, The application place of the L-type cosmetics 1 is not limited to a rising ridge, and is attached to the entrance ridge In addition to the floor covering provided between the floors, it may be a decorative material provided at the corner of the step board of the stairs.
