MODE FOR CARRYING OUT THE INVENTION

[0007] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The door body 1 is used for a sliding door disposed indoors. The door body 1 is formed in a substantially rectangular parallelepiped plate shape with a small thickness, and includes a door body main body 10, a reinforcing portion 2, and a cover member 3.

[0008] The door body main body 10 includes a first panel 11, a second panel 12, and a middle panel 13, and is a plate-shaped portion that connects these to form the outer shape of the door body 1.

[0009] The first panel 11 is a plate-shaped member disposed on the door tip side of the door body 1. The second panel 12 is disposed on the door butt side and is a plate-shaped member having a larger width than the first panel 11. The materials of the first panel 11 and the second panel 12 are not limited, and for example, they may be made of wood or a decorative sheet with a wood grain pattern printed on the surface of a plywood. As shown in FIG. 2, the first panel 11 and the second panel 12 each have a middle panel holding groove 11a, 12a, a reinforcing portion holding groove 11b, 12b, and a cover member holding groove 11c, 12c.

[0010] The middle panel holding grooves 11a and 12a are formed along the adjacent long sides of the first panel 11 and the second panel 12 to have a length that matches the length of the middle panel 13 described later. The middle panel holding grooves 11a and 12a are arranged on the central portion side in the thickness direction on the surface extending in the thickness direction of the first panel 11 and the second panel 12, and are formed by recesses that are recessed in the width direction of the first panel 11 and the second panel 12 from the surface extending in the thickness direction. The middle panel holding grooves 11a and 12a have a cross-sectional shape that matches the widthwise ends of the middle panel 13. Specifically, the middle panel holding grooves 11a and 12a are grooves that are substantially U-shaped in cross-section and open toward the surface extending in the thickness direction of the first panel 11 and the second panel 12, and the bottom surface of the U-shaped groove is formed so as to protrude further toward the center in the width direction at the central portion in the thickness direction of the first panel 11 and the second panel 12.

[0011] The reinforcing part holding grooves 11b and 12b are arranged at the upper and lower ends of the first panel 11 and the second panel 12 on the side where the middle panel 13 is arranged, and are grooves for arranging the reinforcing part 2 described later. The reinforcing part holding grooves 11b and 12b are formed at the upper and lower ends of the first panel 11 and the second panel 12 to have a width and length capable of arranging the reinforcing part 2, and a depth such that the upper and lower surfaces of the reinforcing part 2 do not protrude from the upper and lower ends of the first panel 11 and the second panel 12. As shown in FIG. 2, the reinforcing part holding grooves 11b and 12b are substantially U-shaped in plan view, that is, have a shape in which one end of an ellipse is cut off.

[0012] The cover member holding grooves 11c and 12c are grooves into which a cover member 3 described later can be inserted. The cover member holding grooves 11c and 12c are formed on the U-shaped opening sides of the middle panel holding grooves 11a and 12a. The cover member holding grooves 11c and 12c have a wider width than the reinforcing part holding grooves 11b and 12b in a cross-sectional view seen from a plane extending in the width direction at the upper and lower ends of the first panel 11 and the second panel 12. The cover member holding grooves 11c and 12c are formed to have a wider width than the middle panel holding grooves 11a and 12a in a cross-sectional view seen from a plane extending in the thickness direction of the long sides where the middle panel holding grooves 11a and 12a of the first panel 11 and the second panel 12 are formed. The length (depth) along the long side direction of the first panel 11 and the second panel 12 in the cover member holding grooves 11c and 12c is shorter than that of the middle panel holding grooves 11a and 12a, and is formed to have a length that matches the length of the cover member 3 described later. In the cover member holding grooves 11c and 12c, in a cross-sectional view seen from the upper and lower ends of the first panel 11 and the second panel 12, curved surfaces 11d and 12d that are wider than the reinforcing part holding grooves 11b and 12b are formed at the ends of the reinforcing part holding grooves 11b and 12b facing each other.

[0013] The middle panel 13 is a thin plate-like member disposed between the first panel 11 and the second panel 12, and is composed of, for example, a plate obtained by attaching a decorative sheet to a medium density fiberboard (MDF). The middle panel 13 is made of a material different from the other panels constituting the door body main body 10, that is, the first panel 11 and the second panel 12. One end in the width direction of the middle panel 13 is inserted into and held by the middle panel holding groove 11a of the first panel 11, and the other end is inserted into and held by the middle panel holding groove 12a of the second panel 12. The thickness of the middle panel 13 is thinner than that of the first panel 11 and the second panel 12, and the length of the middle panel 13 is shorter than that of the first panel 11 and the second panel 12. Therefore, in a state where the reinforcing part 2 and the cover member 3 described later are not arranged, a gap G is formed between both longitudinal ends of the first panel 11 and the second panel 12 due to the shortness of the middle panel 13 (see Fig. 5A).

[0014] The reinforcing part 2 is an aluminum frame. The reinforcing part 2 has a dimension that is longer than the length of the middle panel 13 in the width direction and shorter than the length of the door body main body 10 in the width direction. The reinforcing part 2 extends in the width direction from the upper and lower ends of the middle panel 13 and is arranged across the first panel 11 and the second panel 12. As shown in FIG. 3, the reinforcing part 2 has an upper frame 22 and a lower frame 21, and is arranged at the upper end and the lower end of the middle panel 13.

[0015] The upper frame 22 has a fixing part 221, an indoor side surface 222, and an outdoor side surface 223. The fixing part 221 is fixed to the upper surface of the middle panel 13 with screws. The fixing part 221 has a portion bent in a substantially U-shape that protrudes upward arranged at both ends in the thickness direction of the middle panel 13, and a portion bent in a substantially U-shape that protrudes downward arranged at the central portion in the thickness direction, and these are continuously bent in a zigzag shape up and down to have a surface. The indoor side surface 222 and the outdoor side surface 223 are arranged opposite to each other and extend along the outdoor side surface and the indoor side surface of the door body main body 10 respectively.

[0016] As shown in FIG. 3, the lower frame 21 has a hollow part 211 with a substantially hollow shape in cross-section, an indoor side surface 212 extending upward from the outdoor side surface and the indoor side surface of the hollow part 211, and an outdoor side surface 213. The hollow part 211 is fixed to the lower surface of the middle panel 13 with screws. The indoor side surface 212 and the outdoor side surface 213 are arranged opposite to each other and extend along the outdoor side surface and the indoor side surface of the door body main body 10 respectively. A rail member 4 is arranged below the lower frame 21.

[0017] The cover member 3 is a member that covers the surface of the reinforcing portion 2 exposed between the first panel 11 and the second panel. The cover member 3 is a member separate from the middle panel 13, is disposed at the upper and lower ends in the vertical direction of the middle panel 13, and is attached so as to sandwich the reinforcing portion 2 while holding the middle panel 13. As shown in FIG. 2, the cover member 3 includes an upper cover member 320 disposed on the upper end side of the door body main body 10 and a lower cover member 310 disposed on the lower end side. The upper cover member 320 is attached to the upper end side of the middle panel 13 and the upper frame 22, and the lower cover member 310 is attached to the lower end side of the middle panel 13 and the lower frame 21. As shown in FIGS. 4A and 4B, the upper cover member 320 and the lower cover member 310 have different positions in the portion holding the door body main body 10 and different shapes. However, the upper cover member 320 and the lower cover member 310 are generally formed in a substantially H-shaped cross section, and have an indoor side surface portion 31, an outdoor side surface portion 32, a connecting portion 33, a reinforcing portion holding portion 34, and a middle panel sandwiching portion 35 as a sandwiching portion, which are functionally common.

[0018] The indoor side surface portion 31 is a flat surface that covers the indoor side surface 222 of the upper frame 22 and the indoor side surface 212 of the lower frame 21. The indoor side surface portion 31 has a substantially rectangular shape when viewed from the front of the door body main body 10. The surface of the indoor side surface portion 31 has the same pattern as the patterns on the surfaces of the first panel 11 and the second panel 12. For example, as shown in FIGS. 5A to 5C, when the first panel 11 and the second panel 12 have a wood grain pattern, the surface of the indoor side surface portion 31 has a wood grain pattern along the direction of the wood grain of the first panel 11 and the second panel 12. When the patterns of the first panel 11 and the second panel 12 show wood grains along the vertical direction of the door body 1, the pattern of the indoor side surface portion 31 is also shown along the vertical direction of the door body 1.

[0019] The outdoor side surface portion 32 is a flat surface that covers the outdoor side surface 223 of the upper frame 22 and the outdoor side surface 213 of the lower frame 21. The outdoor side surface portion 32 has a substantially rectangular shape when viewed from the front of the door body main body 10. The surface of the outdoor side surface portion 32 has the same pattern as the patterns on the surfaces of the first panel 11 and the second panel 12. For example, as shown in FIGS. 5A to 5C, when the first panel 11 and the second panel 12 have a wood grain pattern, the surface of the outdoor side surface portion 32 has a wood grain pattern along the direction of the wood grain of the first panel 11 and the second panel 12. When the patterns of the first panel 11 and the second panel 12 show wood grains along the vertical direction of the door body 1, the pattern of the outdoor side surface portion 32 is also shown along the vertical direction of the door body 1. The outdoor side surface portion 32 is arranged facing the indoor side surface portion 31.

[0020] The connecting portion 33 is a plate-like portion that connects the indoor side surface portion 31 and the outdoor side surface portion 32. As shown in FIG. 3, the connecting portion 33 extends in a direction orthogonal to the extending direction of the indoor side surface portion 31 and the outdoor side surface portion 32, and is arranged on either the upper or lower side closer to the longitudinal center of the indoor side surface portion 31 and the outdoor side surface portion 32. The connecting portion 33 is arranged to abut against or face the surface in the thickness direction of the middle panel 13 in a state of being attached to the middle panel 13.

[0021] The reinforcing portion holding portion 34 is a substantially U-shaped portion in cross-section formed on the side that holds the upper frame 22 and the lower frame 21 from the connecting portion 33. The reinforcing portion holding portion 34 is surrounded by three surfaces, namely, the portion extending from the connecting portion 33 of the indoor side surface portion 31 and the outdoor side surface portion 32 to the tip side and the connecting portion 33, and holds the upper frame 22 or the lower frame 21 with the opening of the U-shape sandwiched therebetween. As shown in FIGS. 3, 4A, and 4B, in the reinforcing portion holding portion 34, the indoor side surface portion 31 and the outdoor side surface portion 32 extend so as to approach each other as they go from the portion where the connecting portion 33 is formed to the tip side away from the middle panel 13. The indoor side surface portion 31 and the outdoor side surface portion 32 are arranged in a slightly tapered shape in cross-section from the connecting portion 33.

[0022] The middle panel clamping portion 35 is a portion disposed on the side that holds the middle panel 13 from the connecting portion 33. The middle panel clamping portion 35 includes the connecting portion 33 and portions extending from both ends of the connecting portion 33 toward the middle panel 13 side. of In addition to the U-shaped portion on the side in cross-sectional view formed by three sides, it has a clamping end portion 351 that bends inward from the end portion on the opening side of the substantially U-shaped cross-sectional view toward the inside of the opening. In the middle panel clamping portion 35, the tip of the clamping end portion 351 abuts against the surface of the middle panel 13. In the state where the middle panel 13 is clamped, a gap is formed between the portions extending from the connecting portion 33 toward the middle panel 13 side on the indoor side surface portion 31 and the outdoor side surface portion 32 and the surface of the middle panel 13.

[0023] As shown in FIG. 3, the cover member 3 is disposed on the upper end side and the lower end side of the door body main body 10. On the upper cover member 320 side, the middle panel clamping portion 35 clamps the upper end of the middle panel 13 so as to engulf it. On the lower cover member 310 side, the middle panel clamping portion 35 clamps the lower end of the middle panel 13 so as to lightly cover it.

[0024] With reference to FIGS. 5A to 5C, the mounting method of the cover member 3 will be described. FIGS. 5A to 5C show a state where the cover member 3 is mounted on the upper side of the door body main body 10. As shown in FIG. 5A, with the middle panel 13 fixed between the first panel 11 and the second panel 12, the cover member 3 is inserted into the gap G between the first panel 11 and the second panel 12. More specifically, the cover member 3 is inserted between the cover member holding grooves 11c, 12c and the curved surfaces 11d, 12d of the first panel 11.

[0025] Next, as shown in FIG. 5B, the upper frame 22 of the reinforcing portion 2 is inserted into the reinforcing portion holding grooves 11b, 12b of the first panel 11. The reinforcing portion 2 is held by the reinforcing portion holding portion 34 of the cover member 3. Similarly, the lower frame 21 is inserted on the lower end side of the door body main body 10.

[0026] As shown in FIG. 5C, the indoor side surface portion 31 and the outdoor side surface portion 32 of the cover member 3 are exposed at the portion where there is a gap G between the first panel 11 and the second panel 12. The reinforcing portions 2, which are different from the first panel 11 and the second panel 12 in terms of material and color, are concealed by the cover member 3. Since the patterns of the indoor side surface portion 31 and the outdoor side surface portion 32 are formed in the same pattern as those of the first panel 11 and the second panel 12, the cover member 3 is visually recognized as being continuous with the first panel 11 and the second panel 12.

[0027] According to the first embodiment, the following effects are achieved. The door body 1 is configured to include the first panel 11 and the second panel 12, the middle panel 13 disposed between the first panel 11 and the second panel 12, the reinforcing portion 2 disposed across the first panel 11 and the second panel 12 from the upper and lower ends of the middle panel 13 in the vertical direction, and the cover member 3 disposed at the end of the middle panel 13 and covering the surface of the reinforcing portion 2 exposed between the first panel 11 and the second panel 12. Since the cover member 3 covers the surface of the reinforcing portion 2, the reinforcing portion 2 is not visible from the outside of the door body. Thereby, the appearance of the door body 1 is improved. By disposing the cover member 3 at the end of the middle panel 13, the exposed portion of the reinforcing portion 2 can be concealed. Therefore, if the surface of the cover member 3 is decorated in the same pattern as the surfaces of the first panel 11 and the second panel 12 in advance, it is not necessary to perform processes such as decorating the exposed portion of the reinforcing portion 2 later or performing pattern processing over a wide range assuming the exposed portion. Thus, the appearance of the door body can be easily improved.

[0028] According to the first embodiment, the cover member 3 is configured to include the indoor side surface portion 31 covering the indoor side surface of the reinforcing portion 2, the outdoor side surface portion 32 covering the outdoor side surface, and the connecting portion 33 connecting the indoor side surface portion 31 and the outdoor side surface portion 32. Since the cover member 3 has the indoor side surface portion 31 and the outdoor side surface portion 32, the surface of the reinforcing portion 2 is concealed, and the same effect as described above is achieved. Since the indoor side surface portion 31 and the outdoor side surface portion 32 are connected by the connecting portion 33, the surface of the reinforcing portion 2 can be easily covered by simply disposing the cover member 3 on the middle panel 13 and bringing the connecting portion 33 into contact with the middle panel 13.

[0029] According to the first embodiment, the cover member 3 is configured to include a reinforcing portion holding portion 34. The reinforcing portion holding portion 34 is formed in a tapered cross-sectional shape in which the indoor side surface portion 31 and the outdoor side surface portion 32, which are arranged to face each other, approach each other toward the distal end side from the connecting portion 33. Since the indoor side surface portion 31 and the outdoor side surface portion 32 are formed in a tapered cross-sectional shape that approaches each other toward the distal end, it becomes easier to hold the reinforcing portion 2 while the space between the indoor side surface portion 31 and the outdoor side surface portion 32 is narrowing.

[0030] According to the first embodiment, the cover member 3 is configured to include a middle panel sandwiching portion 35 that sandwiches the end portion of the middle panel 13. Since the cover member 3 is arranged between the first panel 11 and the second panel 12, it is possible to stably arrange the middle panel sandwiching portion 35 so as to cover the surface of the reinforcing portion 2 simply by sandwiching the end portion of the middle panel 13. to become.

[0031] According to the first embodiment, the surface of the cover member 3 is configured to have the same pattern as the patterns on the surfaces of the first panel 11 and the second panel 12. Thereby, the cover member 3 gives an impression of being a member continuous with the first panel 11 and the second panel 12, and the appearance of the door body 1 can be improved. By decorating only the surface of the cover member 3, it can be made to match the patterns of the first panel 11 and the second panel 12. When the patterns of the first panel 11 and the second panel are wood grain patterns along the vertical direction, a pattern may be provided on the surface of the cover member 3 along the direction of the wood grain of the first panel 11 and the second panel. If an attempt is made to match the patterns of the first panel 11 and the second panel 12 by providing a pattern on the surface of the reinforcing portion without providing the cover member 3, it is difficult to accurately predict which position the gap G between the first panel 11 and the second panel 12 corresponds to, so it is necessary to decorate with a width larger than the gap G. Also, when the pattern is a wood grain pattern, if an attempt is made to provide a wood grain pattern along the reinforcing portion, a situation may occur where the direction of the wood grain is along the width direction of the door body main body 10. According to the first embodiment, it becomes possible to provide a pattern that harmonizes with the first panel 11 and the second panel 12 on the door body main body 10 without taking extra trouble just by attaching the cover member 3.

[0032] The present disclosure is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope that can achieve the object of the present disclosure are included in the present disclosure. As shown in FIGS. 6A and 6B, in the cover member 3A of the second embodiment, the indoor side surface portion 31 and the outdoor side surface portion 32 are not formed in a substantially rectangular shape in a front view of the indoor side surface portion 31 and the outdoor side surface portion 32.

[0033] FIG. 6A shows the lower cover member 310A of the cover member 3A disposed below the upper suspension door. The indoor side surface portion 31A and the outdoor side surface portion 32A of the lower cover member 310A are formed such that the width of the side where the middle panel sandwiching portion 35A is disposed is narrow and the width of the side where the reinforcing portion holding portion 34A is disposed is wide in a front view of the indoor side surface portion 31A and the outdoor side surface portion 32A, and are formed to have a step in the width direction in a front view of the indoor side surface portion 31A and the outdoor side surface portion 32A.

[0034] As shown in FIG. 6B, in the second embodiment, the first panel 11A and the second panel 12A are different from the first embodiment in that they do not have the cover member holding grooves 11c, 12c and the curved surfaces 11d, 12d. The first panel 11A and the second panel 12A have middle panel holding grooves 11a, 12a for holding the middle panel 13 and reinforcing part holding grooves 11e, 12e. The reinforcing part holding grooves 11e, 12e of the second embodiment are formed wide along the thickness direction of the first panel 11 and the second panel 12 so as to also serve as the cover member holding grooves 11c, 12c. Since the cover member holding grooves 11c, 12c and their curved surfaces 11d, 12d are not separately formed from the reinforcing part holding grooves 11e, 12e, the process of forming the grooves can be omitted.

[0035] In the cover member 3A, the width on the side where the reinforcing part holding part 34A is arranged is wider. In the case of the cover member 3A, while adjusting the indoor side surface part 31A and the outdoor side surface part 32A left and right, alignment is performed so that the middle panel sandwiching part 35A is positioned between the first panel 11 and the second panel 12.

[0036] FIG. 7 shows a cover member 3B according to a modified example of the second embodiment. The configuration of the cover member 3B and the configuration of the grooves of the first panel 11B and the second panel 12B are common to the second embodiment. The cover member 3B according to the modified example has a higher height of the middle panel sandwiching part 35B than the reinforcing part holding part 34B compared to the cover member 3A of the second embodiment. However, the total height of the middle panel sandwiching part 35B and the reinforcing part holding part 34B combined is the same as the height of the cover member 3A of the second embodiment. The cover member 3B may be arranged on the upper side or the lower side of the door body according to the arrangement of other parts of the door body. The cover member may be appropriately shaped according to the type of the door body and its vertical arrangement, etc.

[0037] The dimensions and materials of the first panel 11, the second panel 12, and the middle panel 13 can be appropriately changed according to the appearance design. There may be a plurality of second panels and middle panels, such as panels with different materials arranged alternately. The patterns of the first panel 11 and the second panel 12 do not have to be wood-grain-like. The door body may be a sliding door with door wheels arranged on the lower side, or a hanging sliding door with door wheels arranged on the upper side. The shape of the door body or the door body main body is not limited to a rectangle. The specific shapes of the middle panel, the reinforcing part holding groove, the cover member holding groove, etc. may be appropriately changed.
