[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] 1 to 6 are six-sided views of a cover 1 (hereinafter, simply referred to as cover 1) for a joint of a curtain rail according to an embodiment of the present invention. FIG. 7 is a perspective view of the cover 1, and FIG. 8 is another perspective view of the cover 1. FIG. 9 is a side view of the cover 1, and FIG. 10 is a plan view of the cover 1. In contrast to FIGS. 1, 2, 5, and 6, FIGS. 9 and 10 have reference numerals for each component. Hereinafter, for convenience of explanation, the side in the direction of arrow a (see FIG. 10) is referred to as the upper side, and the side in the direction of arrow b (see FIG. 10) is referred to as the lower side. Note that the upper side and the lower side do not limit the position of the cover 1 in space, and the cover 1 can take any position in space.

[0016] 1 to 10, cover 1 has side portions 11, 12 which are a pair of portions facing each other, and an upper portion 13 which is a portion connecting the pair of side portions 11, 12. The pair of side portions 11, 12 are adapted to cover from the inside the sides of a joint (hereinafter also simply referred to as a joint) of a curtain rail to which cover 1 is to be attached, and upper portion 13 is adapted to cover from the inside the upper portion of the joint to which cover 1 is to be attached. The configuration of cover 1 will be specifically described below.

[0017] Cover 1 is an inner member that is housed in a space through which the runner of the joint to be attached runs, and has a shape that corresponds to this space. Cover 1 is made of resin, and is molded from a colored resin material. Cover 1 is made as a single piece, and side portions 11, 12 and top portion 13 are parts of the single cover 1 that are formed from the same material. However, cover 1 may be made of other materials.

[0018] As shown in Figures 1 to 10, cover 1 is a member that extends along a straight line, and extends corresponding to the joint to which it is attached. Cover 1 also has a space for a runner that runs along a curtain rail to pass through, and this space is defined by side portions 11, 12 and an upper portion 13. Side portion 11, side portion 12, and upper portion 13 each extend along a plane, for example, each extend parallel or approximately parallel to the plane. Note that the plane along which side portion 11, side portion 12, and upper portion 13 each extend is an imaginary plane.

[0019] 1 to 10, each of the side portions 11, 12 is a plate-like portion that extends along a plane as described above, for example, parallel or approximately parallel to the plane. Each of the side portions 11, 12 corresponds to a side of a joint to which the side portions are attached, and is shaped to overlap and cover the side of the joint from the inside in a usage state described below.

[0020] 9, lower edges 14a, 15a of end portions 14, 15 in the extension direction of side portion 11 extend at an angle upward from lower edge 16 of the portion between end portions 14 and 15 of side portion 11, and end portions 14, 15 of side portion 11 have a tapered shape. Edges 14a, 16, 15a of side portion 11 have the same or approximately the same shape as the lower edge of the side of the joint to which they are attached.

[0021] 9, side portion 12 is similar to side portion 11, and lower edges 14a, 15a of ends 14, 15 in the extension direction of side portion 12 extend at an angle upward from lower edge 16 of the portion between ends 14 and 15 of side portion 12, and ends 14, 15 of side portion 12 have a tapered shape. Edges 14a, 16, 15a of side portion 12 have the same or approximately the same shape as the lower edge of the side of the joint to which they are attached.

[0022] As shown in FIG. 10, the side portions 11 and 12 each extend downward from a pair of opposing edges 13c of the upper portion 13. For example, the side portions 11 and 12 extend such that the distance between them becomes wider as they extend downward, and the distance between the side portions 11 and 12 in the opposing direction becomes larger as they extend from the upper portion 13 toward the edges 14a, 15a, and 16 of the side portions 11 and 12. That is, the edges 14a, 15a, and 16 of the side portion 11 that are lower than the connection portion of the side portion 11 with the upper portion 13 are positioned outside, and for example, the side portion 11 is inclined outward relative to the upper portion 13. Similarly, the edges 14a, 15a, and 16 of the side portion 12 that are lower than the connection portion of the side portion 12 with the upper portion 13 are positioned outside, and for example, the side portion 12 is inclined outward relative to the upper portion 13. In this manner, the distance between the side portions 11 and 12 in the opposing direction of the side portions 11 and 12 (the width direction of the cover 1) becomes wider toward the edges 14a, 15a, and 16.

[0023] Furthermore, the distance between side portions 11 and 12 of cover 1 in the width direction at edges 14a, 16, and 15a is the same as or larger than the distance between the inner faces of the opposing sides in the width direction of the joint to be attached. Note that sides 11 and 12 of cover 1 do not have to be inclined outward relative to top 13, and the distance between side portions 11 and 12 of cover 1 in the width direction may be the same or approximately the same.

[0024] 1 to 10, the upper portion 13 is specifically a plate-like portion and extends along a plane as described above, for example, parallel or approximately parallel to the plane. The upper portion 13 corresponds to the upper portion of the joint to which it is attached, and is shaped to overlap the upper portion of the joint from the inside and cover the upper portion of the joint from the inside in a usage state described later. The upper portion 13 connects the side portion 11 and the side portion 12 at the upper edges of the side portion 11 and the side portion 12.

[0025] As shown in Figs. 7 and 10, the upper part 13 may have a step 13a that is a recessed portion inside the cover 1, and the upper part 13 may be connected to the side parts 11 and 12 via the step 13a. Also, as shown in Figs. 9 and 10, the upper part 13 has a protrusion 13b that protrudes upward. The protrusion 13b of the upper part 13 corresponds to a through hole formed in the upper part of the joint to which the cover 1 is attached, and when the cover 1 is attached to the joint so that the side parts 11 and 12 and the upper part 13 of the cover 1 overlap the side parts and the upper part of the joint, respectively, the protrusion 13b of the cover 1 is accommodated in the through hole of the joint. In other words, the protrusion 13b of the cover 1 and the through hole of the joint serve as a guide to ensure that the cover 1 is attached to the joint in an appropriate position.

[0026] In the cover 1, the thicknesses of the side parts 11, 12 and the upper part 13 may be the same or approximately the same, and the thicknesses of the side parts 11, 12 may be the same or approximately the same. In the illustrated example, the thicknesses of the side parts 11, 12 are the same or approximately the same, and the thickness of the part of the upper part 13 excluding the step part 13a is thicker than the thickness of the side parts 11, 12. The structure regarding the thickness of the upper part 13 is not limited to this. As shown in Fig. 7, a rib 13d may be formed on the upper side of the upper part 13 to increase strength.

[0027] Next, the operation of the cover 1 having the above-mentioned configuration will be described. Fig. 11 is a perspective view of the joint 50 to which the cover 1 is attached, and Fig. 12 is a cross-sectional view of the joint 50 to which the cover 1 is attached. Fig. 13 is a perspective view of the curtain rail 60 connected by the joint 50 to which the cover 1 is attached.

[0028] The cover 1 is attached to the joint 50 by being inserted into the joint 50 from the end 54 or end 55 side of the joint 50. In a use state in which the cover 1 is attached to the joint 50, the side portion 11 of the cover 1 covers the inner surface 51a of the side portion 51 of the joint 50, and the side portion 12 of the cover 1 covers the inner surface 52a of the side portion 52 of the joint 50. In addition, in a use state of the cover 1, the upper portion 13 of the cover 1 covers the inner surface 53a of the upper portion 53 of the joint 50. In a use state, the cover 1 does not cover the inner surfaces 56a, 57a of the running portions 56, 57 of the joint 50. However, the edges 16 which are the lower ends of the respective side portions 11, 12 of the cover 1 are in contact with the inner surfaces 56a, 57a of the running portions 56, 57 of the joint 50. The edges 16 of the sides 11 , 12 of the cover 1 do not have to be in contact with the inner surfaces 56 a , 57 a of the running portions 56 , 57 of the joint 50 .

[0029] As described above, the distance between the side portion 11 and the side portion 12 of the cover 1 in the width direction at the edges 14a, 16, and 15a is equal to or larger than the distance between the inner surface 51a of the side portion 51 and the inner surface 52a of the side portion 52 in the width direction of the joint 50. Therefore, as shown in FIG. 12, the holding force of the cover 1 against the joint 50 acts in the width direction of the cover 1 at the lower ends of the sides 11 and 12 of the cover 1. The holding force of the cover 1 against the joint 50 may also act in the vertical direction. Specifically, the upper portion 13 of the cover 1 and the edges 16 of the sides 11 and 12 may be sandwiched between the upper portion 53 of the joint 50 and the running portions 56 and 57 to hold the cover 1 against the joint 50. For example, the step 13a of the upper part 13 of the cover 1 and the edges 16 of the side parts 11, 12 may be sandwiched between the step 53b of the upper part 53 of the joint 50 and the running parts 56, 57 to hold the cover 1 against the joint 50.

[0030] 12, a gap is formed between the upper portion 13 of the cover 1 and the upper portion 53 of the joint 50. This gap makes it possible to easily insert the cover 1 into the inside of the joint 50. Note that it is also possible that no gap is formed between the upper portion 13 of the cover 1 and the upper portion 53 of the joint 50.

[0031] The protrusion 13b of the upper portion 13 of the cover 1 corresponds to the through hole 53c formed in the upper portion 53 of the joint 50, and in the used state, the protrusion 13b of the cover 1 is accommodated in the through hole 53c of the joint 50. In this way, the protrusion 13b of the cover 1 and the through hole 53c of the joint 50 act as guides that allow the cover 1 to be attached to the joint 50 in an appropriate position, and the cover 1 can be easily attached to the joint 50 in an appropriate position.

[0032] As described above, in use, the cover 1 covers the inner surface 53a of the upper portion 53 of the joint 50 and the inner surfaces 51a, 52a of the side portions 51, 52. Therefore, even if the joint 50 is made of shiny stainless steel, the joint 50 can be made non-shiny or less shiny, making the joint 50 less noticeable on the curtain rail 60. In particular, if the cover 1 is the same color or approximately the same color as the curtain rail 60, the joint 50 can be made even less noticeable on the curtain rail 60.

[0033] As described above, in the used state, the cover 1 does not cover the running parts 56, 57 of the joint 50, but in the curtain rail 60, the lower surfaces of the running parts 56, 57 of the joint 50 are covered by the lower part 61 of the curtain rail 60. Therefore, even in the used state, the inner surfaces 56a, 57a of the running parts 56, 57 of the joint 50 may be glossy, but the inner surfaces 56a, 57a of the running parts 56, 57 of the joint 50 cannot be seen from below, and the gloss of the inner surfaces 56a, 57a of the running parts 56, 57 is not noticeable.

[0034] In this way, by attaching the cover 1, the gloss of the joint 50 can be made less noticeable, and the joint 50 can be made less noticeable on the curtain rail 60. This can improve the design of the joint 50, and ultimately the design of the curtain rail 60.

[0035] As described above, according to the cover 1 of the embodiment of the present invention, it is possible to prevent the design of the curtain rail from being impaired.

[0036] Although the embodiment of the present invention has been described above, the present invention is not limited to the cover 1 according to the embodiment of the present invention, but includes all aspects included in the concept of the present invention and the scope of the claims. In addition, each configuration may be appropriately and selectively combined so as to achieve at least a part of the above-mentioned problems and effects. For example, the shape, material, arrangement, size, etc. of each component in the above embodiment may be appropriately changed depending on the specific usage mode of the present invention.

[0037] For example, the shape of the cover is not limited to the above-mentioned shape and can be changed according to the shape of the joint to which the cover is attached. Also, the cover 1 may have a recess or a through hole instead of the protrusion 13b of the upper part 13, and in this case, the upper part 53 of the joint 50 has a protrusion instead of a through hole 53c.
