A curtain rail device to which the present invention is applied will be described below with reference to the drawings.
[First Embodiment]
As shown in FIGS. 1 and 2, the curtain rail device 1 includes a curtain rail 2, a bracket 3 for attaching the curtain rail 2 to a mounting surface 6, and an outer peripheral portion of the curtain rail 2, which moves along the longitudinal direction. It has a C-shaped runner 4 as a flexible curtain runner and a runner stopper 8 for regulating the position of the C-shaped runner 4. - 特許庁The curtain rail device 1 is a device that suspends and supports a curtain 7 such as a drape curtain so as to be movable along the longitudinal direction of the curtain rail 2, and is attached near a window of a building, a vehicle, or the like, for example. Each rail end portion of the curtain rail 2 in the longitudinal direction protrudes outward from the bracket 3, and each rail end portion is provided with a finial 5 which is a decorative member for decorating the rail end portion of the curtain rail 2. there is The curtain rail 2 is fixed to the mounting surface 6 by brackets 3 .

The curtain rail 2 is an elongated member and includes a rail body 11 and a finial 5 which is a decorative member for decorating the rail end of the rail body 11. - 特許庁One end of the upper edge of the curtain 7 is suspended from a C-shaped runner 4a positioned closest to one rail end (the left end as viewed from the front) of the curtain rail 2, and is suspended by a runner stopper 8 from the curtain rail. 2 is fixed so as not to move in the opening/closing direction, which is the longitudinal direction of . On the other hand, the other end of the upper edge of the curtain 7 is suspended from the leading C-shaped runner 4b located on the other rail end (the right end as viewed from the front) side of the curtain rail 2 . Therefore, the curtain 7 is held in a pulled-out state by moving the leading C-shaped runner 4b in the direction of the arrow D, which is the direction in which the curtain 7 is closed. Further, the curtain 7 is folded by being moved in the direction opposite to the arrow D, which is the direction in which the curtain 7 is opened.

The rail body 11 is an elongated shaped member from which the curtain 7 is hung via the C-shaped runners 4 . Specifically, as shown in FIG. 3, the rail body 11 is formed by extruding a metal material, and has the same shape in a side view (cross-sectional view) viewed from a direction orthogonal to the longitudinal direction. have. Such a rail body 11 has a basic circular shape with the same radius when viewed from the side. The rail main body 11 has a design surface portion 12 that protrudes in one direction in a semicircular shape in a side view. That is, the design surface portion 12 is a curved surface that bulges in one direction with respect to an imaginary plane 11b that passes through the center 11a of the rail body 11 and extends in the longitudinal direction of the rail body 11 when viewed from the side. Here, one direction is, for example, the front direction facing the room when the curtain rail 2 is attached to the attachment surface 6 by the bracket 3 .

The rail body 11 has a protruding portion 13 at a position corresponding to the upper end portion of the design surface portion 12 in a side view. That is, the projecting portion 13 is provided at the top of the rail body 11 through which the imaginary plane 11 b passes, and projects from the curved surface forming the design surface portion 12 . One end of the projecting portion 13 on the design surface portion 12 side is one end of the design surface portion 12 . The other end of the design surface portion 12 is located on the opposite side of the protruding portion 13 and extends to the bottom or fixed portion 21 through which the imaginary plane 11b passes. The protruding portion 13 protrudes from the surroundings so that the operator can visually and tactilely identify one end of the design surface portion 12 . In addition, the projecting portion 13 is also a position where the inner peripheral surface of the C-shaped runner 4 abuts and travels when the curtain 7 is suspended. A decorative tape 12a is adhered to the design surface portion 12 specified in this way on the rail body 11 . Here, a wood grain design is applied.

It should be noted that the design surface portion 12 and the entire outer peripheral surface including the design surface portion 12 may be provided with a design by hydraulic transfer processing. In hydraulic transfer processing for coating the surface of a resin member, a pattern film is floated on the water surface, and the design surface part 12 to which the pattern is to be applied is submerged from above with the outer peripheral surface facing the water surface to transfer the pattern to the outer peripheral surface. That is, only the ink carried on the film is transferred onto the design surface portion 12 and the entire outer peripheral surface including the design surface portion 12 . According to hydraulic transfer processing, a design can be applied to the entire outer peripheral surface including the design surface portion 12 formed into a curved surface and the design surface portion 12 . After painting, the surface may be top-coated (clear-coated) to protect the paint.

The rail body 11 has an attachment portion 14 to which the bracket 3 is attached on the back side opposite to the design surface portion 12 in a side view. The rail body 11 includes an outer peripheral plate portion 10 protruding toward the back side from the other end portion of the protruding portion 13 on the back side. The outer peripheral plate portion 10 is a curved piece that curves and extends from the top portion toward the back side. The mounting portion 14 is provided next to the outer peripheral plate portion 10 on the back side and faces the design surface portion 12 . The outer peripheral plate portion 10 is extended so as to wrap around to the back side of the rail body 11 , so that the tip thereof is positioned lower than the projecting portion 13 . As a result, the outer peripheral plate portion 10 makes it difficult to see the attachment portion 14 from the front side.

The mounting portion 14 is a mounting groove having an inward V-shaped concave shape on the back side of the rail body 11 . The mounting portion 14 includes a support surface 15 on which the bracket 3 is supported, and a guide surface 16 that guides the bracket 3 inserted into the mounting portion 14 . An opening end 17 of the attachment portion 14 is located on the back side of the rail body 11 . An upper end portion of the open end 17 is a tip portion of the outer peripheral plate portion 10 .

The support surface 15 is a horizontal surface extending from the back side to the front side, and is provided closer to the bottom side than the center 11a. The support surface 15 has a positioning recess 18 in the middle. A positioning protrusion of the bracket 3 is engaged with the positioning recess 18 . A guide surface 16 extending from the innermost end of the support surface 15 extends obliquely upward with respect to the support surface 15 . The support surface 15 and the guide surface 16 are provided so as to widen from the innermost portion toward the open end 17, so that the insertion opening of the bracket 3 is widened.

At the innermost portion formed by the support surface 15 and the guide surface 16, the guide surface 16 protrudes inward from the surface on the side of the opening end 17 via a step 16a, and engages with the tip portion of the bracket 3. A joint recess 19a is formed. The engaging recess 19a is located at the innermost part of the recesses forming the mounting portion 14. As shown in FIG. The upper end of the open end 17 , that is, the tip of the outer peripheral plate portion 10 serves as a guide portion 19 with which the guide protrusion 45 of the C-shaped runner 4 is engaged. The lower end of the open end 17 , that is, the end of the support surface 15 serves as the engaged portion 20 with which the support member 34 of the bracket 3 is engaged.

On the other hand, the bracket 3 has an engaging protrusion 31 at its tip and an engaging stepped portion 32 that engages with the stepped portion 16a on the upper surface side. The bracket 3 also has a positioning projection 33 on the lower surface side, which is engaged with the positioning recess 18 . Further, the bracket 3 is provided with a support member 34 at a position biased toward the attachment portion to the attachment surface 6 on the lower surface side. The support member 34 has a support projection 35 that engages the engaged portion 20 at the end of the support surface 15 . The support member 34 protrudes in the direction in which it engages with the engaged portion 20, that is, in the projecting direction of the support projection 35, by means of an elastic member such as a coil spring as a separate member or an integral elastic portion.

Next, a method for attaching the rail body 11 to the bracket 3 will be described. When attaching the rail body 11 to the bracket 3 , the engaging projection 31 of the bracket 3 is inserted into the open end 17 of the rail body 11 . At this time, the engaging protrusion 31 can be inserted inside the open end 17 along the inclined guide surface 16 . Then, the engaging projection 31 is engaged with the engaging recess 19a. Thereafter, the rail body 11 is rotated upward so that the support surface 15 approaches the lower surface of the bracket 3 with this engaging portion as a fulcrum. Thereby, the positioning protrusion 33 is engaged with the positioning recess 18 . At this time, the engaged portion 20 is engaged with the support protrusion 35 of the support member 34 . As a result, the rail body 11 is attached to the bracket 3 .

When removing the rail body 11 from the bracket 3 , the engaged state between the engaged portion 20 and the support projection 35 is released by pressing the support member 34 in the anti-projection direction. This allows the rail body 11 to be easily removed from the bracket 3 .

A C-shaped runner 4 can be attached to the curtain rail 2 attached to the bracket 3 as described above. A part of a circular shape with the same radius is cut out from the basic shape to form a C shape as a whole. The C-shaped runner 4 has a first end 41 and a second end 42 which are separated from each other to form a gap therebetween. Here, the first end portion 41 is the end portion positioned on the upper side when the curtain rail 2 is inserted through the outer periphery, and the second end portion 42 is the end portion positioned on the lower side. The C-shaped runner 4 has an inner diameter larger than the outer diameter of the rail body 11, and when the upper side of the inner peripheral surface is in contact with the projecting portion 13 of the rail body 11, the C-shaped runner 4 is formed in the other region. A gap 39 is formed between the runner 4 and the rail body 11 (see FIG. 2). The inner peripheral member 43 and the outer peripheral member 44 constitute the runner main body 40 by combining the outer peripheral member 44 with the outer peripheral side of the inner peripheral member 43 . Furthermore, the C-shaped runner 4 has a decorative member 47 attached to the outer peripheral side of the runner body 40 .

The inner peripheral member 43 has a C-shape and is made of a resin material having excellent abrasion resistance, such as high-density polyethylene (HDPE). The inner peripheral member 43 has a guide projection 45 engaged with the guide portion 19 which is the upper end portion at the opening end 17 of the mounting portion 14 . The guide protrusion 45 has a hook shape so as to engage with the guide portion 19 . As a result, even if an upward force is applied to the rail body 11 , the guide protrusion 45 is less likely to disengage from the guide portion 19 . The guide protrusions 45 are engaged with the guide portions 19 to maintain the posture in which the hooks 46 as suspension portions for suspending the curtain 7 hang vertically from the runner body 40 .

The outer peripheral member 44 also has a C-shape as a whole, but is formed to be one size larger than the inner peripheral member 43 . The outer peripheral member 44 is made of a metal material having higher rigidity than the inner peripheral member 43 such as iron. Therefore, the outer peripheral member 44 is a metal member and serves as a strength member in the C-shaped runner 4 .

The decorative member 47 also has a C shape as a whole, but is formed to be one size larger than the outer peripheral member 44 . The decorative member 47 may be a wooden member or a resin member. When the inner peripheral member 43 and the outer peripheral member 44 are combined to form the runner body 40 , the decorative member 47 is combined with the outer peripheral side of the runner body 40 .

A hook 46 with which the upper end of the curtain is engaged is attached to the C-shaped runner 4 constructed as described above. The hook 46 has its mounting shaft inserted through the mounting hole of the inner peripheral member 43, the mounting hole of the outer peripheral member 44, and the mounting hole of the decorative member 47 located near the second end 42, and the tip thereof is crimped. attached to the C-shaped runner 4 by The hook 46 is rotatable with respect to the runner body 40 in which the outer peripheral member 44 is combined with the inner peripheral member 43 , and is rotatable in accordance with the direction of tensile force from the curtain 7 .

In the C-shaped runner 4 configured as described above, the distance C between the first end portion 41 and the second end portion 42 is smaller than the diameter D of the rail body 11, and the guide projection 45 is engaged with the guide portion 19. The dimensions are set so that the rail body 11 can pass through when they are mated together, and the C-shaped runner 4 is less likely to come off the rail body 11 (see FIG. 2). When attaching the C-shaped runner 4 to the rail body 11, first, the guide projection 45 is engaged with the guide portion 19, and then the first end portion 41 and the second end portion 42 are rotated around this engagement position. The rail body 11 is rotated so as to pass through the inside of the C-shaped runner 4 at the interval between them. The C-shaped runner 4 mounted in this manner faces the rear side of the rail body 11 with the open end composed of the first end portion 41 and the second end portion 42, and is viewed from the front like a ring-shaped runner. be.

Also, the distance C between the first end portion 41 and the second end portion 42 is greater than the height H of the bracket 3 . As a result, when the C-shaped runner 4 moves along the rail body 11 while being in contact with the projecting portion 13, the first end portion 41 and the second end portion 42 do not collide with the bracket 3. Even if it is an attachment part of the

As shown in FIG. 4, the finial 5 as a decorative member attached to each end of the rail body 11 includes a base 51 fixed to each rail end of the rail body 11 and an attachment member attached to the base 51. 52. The base 51 has a relatively flat cylindrical shape and is a base for attaching the attachment member 52 to the rail end of the rail body 11 . Attachment member 52 has an elongated frusto-conical shape and occupies the major decorative element of finial 5 . The thickness from the proximal end to the distal end of the finial 5 may be a thickness that allows the C-shaped runner 4 to pass therethrough, or may be a thickness that prevents the finial 5 from passing therethrough. When the thickness of the finial 5 is such that the C-shaped runner 4 cannot be inserted, it is possible to prevent the C-shaped runner 4 from falling off from the end of the rail body 11 . If the thickness of the finials 5 is such that the C-shaped runner 4 can be inserted, runner stoppers 8 are attached to the respective ends of the rail body 11 to prevent the C-shaped runner 4 from falling off from the rail body 11 . can be prevented.

As shown in FIGS. 5 and 6, the base 51 includes a cylindrical outer peripheral wall 56 and a partition wall that separates a space on the side of the connecting end of the outer peripheral wall 56 with respect to the rail body 11 and a space on the side of the connecting end with respect to the attachment member 52. 57. The base 51 forms a fitting recess 58 into which the rail end of the rail main body 11 is fitted in a space surrounded by the outer peripheral wall 56 on the connecting end side to which the rail end of the rail main body 11 is connected. The bottom surface of the fitting recess 58 is a facing surface facing the end surface of the rail end portion and is constituted by the partition wall 57 . In addition, the base 51 has a fitting wall 59 fitted with the attachment member 52 on the side of the connecting end to which the attachment member 52 is connected.

As shown in FIG. 6 , the base 51 is fixed to the rail end of the rail body 11 by a fixing mechanism 61 . A fixing mechanism 61 between the rail end and the base 51 is configured as follows. A fixing portion 21 for fixing the finial 5 is provided in the rail main body 11 at a position adjacent to the other end portion of the design surface portion 12 (bottom portion of the rail main body 11). In other words, the fixing portion 21 as the fixing mechanism 61 is located between the other end portion of the design surface portion 12 and the mounting portion 14 and deviated toward the back side of the imaginary plane 11b. In this manner, the fixed portion 21 is provided at a position that is difficult to be visually recognized by the occupant on the front side. The fixing portion 21 includes a fixing groove 23 penetrating the outer peripheral plate portion 22 forming the outer peripheral portion of the rail main body 11, and fixing metal fittings forming a fixing mechanism 61, which are continuously formed inside each end portion of the fixing groove 23. and a space 24 into which the second piece 62b of 62 is inserted. A projecting portion 25 on the back side of the positioning concave portion 18 faces the space portion 24 . The rail main body 11 having such a configuration has the mounting portion 14 and the fixing portion 21, and thus is asymmetrical in front and rear in a side view. That is, the side surface of the rail body 11 has an asymmetrical shape with respect to an axis passing through the center 11a (see FIG. 3) and extending at least vertically (here, front-back and top-bottom).

The base 51 is fixed to the rail end of the rail body 11 using the fixing portion 21 as described above. That is, the fixing mechanism 61 on the base 51 side includes a fixing metal fitting 62 , a tapping screw 63 as a fixing member for fixing the fixing metal fitting 62 to the base 51 , and a screw for fixing the fixing metal fitting 62 to the end of the rail body 11 . A fixing screw 64 serving as a fixing member is provided.

The fixing bracket 62 is an L-shaped bracket having a first piece 62a and a second piece 62b. The first piece 62a is a piece fixed to the base 51 and has a through hole 62c. The through hole 62c is positioned at the center of the partition wall 57 when attached to the base 51 . The second piece 62b has pressing pieces 62d on three sides of the tip, and a fixing hole 62e formed of a screw hole at a position surrounded by the pressing pieces 62d. A fixing screw 64 is tightened into the fixing hole 62e. The second piece 62b has a length such that the pressing piece 62d and the fixing hole 62e protrude from the end of the outer peripheral wall 56. As shown in FIG. When the second piece 62b is inserted into the space 24, the tip of the pressing piece 62d is pressed against the inner surface of the outer peripheral plate portion 22 around the fixed groove 23. As shown in FIG.

A positioning groove 65 having a sector shape in a side view is provided on the bottom surface of the fitting recess 58 formed by the partition wall 57 that partitions the inside of the base 51 . The positioning groove 65 is formed of a concave portion that spreads like a fan from the center of the circular partition wall 57, and the first piece 62a of the fixture 62 is arranged. A central hole 66 into which a tapping screw 63 is tightened is provided in the central portion of the circular partition wall 57 within the positioning groove 65 . One radial portion of the positioning groove 65 serves as a first restricting wall 65a for positioning the first piece 62a at the first position, and the other radial portion serves as a second restricting wall 65a for positioning the first piece 62a at the second position. It becomes the wall 65b. That is, the first position and the second position are line-symmetrical with respect to an axis of symmetry 70 that passes through the center of the partition wall 57 and extends vertically (see FIGS. 7 and 8).

The first piece 62a is rotated between the first and second positions with the through hole 62c and the center hole 66 aligned and the tapping screw 63 tightened, but with the tapping screw 63 loosened. be. The tapping screw 63 is positioned at the first position with the first piece 62a abutting against the first regulation wall 65a, or at the second position with the first piece 62a abutting against the second regulation wall 65b. It is tightened in a closed state.

By the way, the fixed groove 23 is made difficult to be visually recognized by the occupants on the front side by displacing the fixed groove 23 toward the back side of the imaginary plane 11b. Along with this, the base 51 is attached to one rail end of the rail body 11 (the left end as viewed from the front) and to the other rail end of the rail body 11 (the right end as viewed from the front). When attached, the front and rear sides of the end portion of the rail body 11 are reversed. Specifically, for example, FIG. 6 shows a base 51 and a fixing mechanism 61 attached to the right rail end of the rail body 11 . The fixture 62 is placed at the second position when the finial 5 is attached to the right rail end. However, when the finial 5 is attached to the left rail end, if the fixing bracket 62 is left at the second position, the fixing bracket 62 will be shifted forward of the imaginary plane 11b of the rail body 11, and the fixing groove The position does not match with 23.

Therefore, as shown in FIG. 7(a), when the base 51 is attached to one rail end (the left end as viewed from the front) of the rail body 11, the first piece 62a is positioned on the right side in FIG. , is abutted against the first regulation wall 65a and positioned at the first position. As shown in FIG. 8(a), when attaching the base 51 to the other rail end of the rail body 11, the base 51 is horizontally reversed from the state shown in FIG. The first piece 62a is located on the left side in FIG. 8 and is abutted against the second restricting wall 65b to be positioned at the second position.

A first index portion 67a is provided at a position adjacent to the first regulation wall 65a. The first index portion 67a is described as "left" here. A second index portion 67b is provided at a position adjacent to the second restricting wall 65b. The second indicator portion 67b is described as "right" here. As shown in FIG. 7(a), when the base 51 is attached to one rail end of the rail body 11, the first piece 62a is attached to the first regulation wall 65a adjacent to the character "left" of the first indicator portion 67a. Positioned close together. Further, as shown in FIG. 8A, when the base 51 is attached to the other rail end of the rail body 11, the first piece 62a is attached to the second restricting wall adjacent to the character "right" of the second indicator portion 67b. 65b. The configurations of the first index portion 67a and the second index portion 67b are not limited to the Chinese characters "Right" and "Left", but may be alphabetical notations such as "R" and "L" or symbols. may

As shown in FIG. 5, the attachment member 52 has a fitting recess 69 into which the fitting wall 59 of the base 51 is fitted. The fitting wall 59 of the base 51 is fitted into the fitting recess 69 by press fitting. Thereby, the attachment member 52 is integrated with the base 51 . The fitting wall 59 may be simply press-fitted into the fitting concave portion 69, or may be further firmly fixed with an adhesive or the like.

9(a) and 9(b) show patterns forming the design of the attachment member 52, where (a) is a front view and (b) is a side view. Moreover, the attachment member 52 has a symmetrical shape in the front-rear direction. That is, in a side view, the shape on the front side and the shape on the back side are the same with respect to the first imaginary plane 68a that passes through the center extending in the longitudinal direction and extends vertically. As a result, the attachment member 52 can be attached to one rail end of the rail body 11 (the left end as viewed from the front) and to the other rail end of the rail body 11 (the right end as viewed from the front). Although the front and back are reversed when attached, at least the front and back have a symmetrical shape, so the design of the shape looks bilaterally symmetrical when viewed from the front. The attachment member 52 is provided so as to have the same shape with respect to a second imaginary plane 68b that passes through the center extending in the longitudinal direction and extends in the front-rear direction.

The attachment member 52 has a wood grain pattern as a design. The attachment member 52 has the same pattern on the front side and the pattern on the back side with respect to a first imaginary plane 68a extending vertically through the center extending in the longitudinal direction in a side view. . Specifically, the pattern on the front side of the attachment member 52 extends and spreads from the base end side to the tip end side in a semi-annular grain pattern. The pattern on the rear side of the attachment member 52 also has semi-annular wood grains that extend and spread from the base end side to the tip end side. The patterns on the front side and the back side are provided so as to be symmetrical with respect to the second imaginary plane 68b extending in the front-rear direction and passing through the center extending in the longitudinal direction. Such a design of the attached member 52 can be applied by, for example, water pressure transfer processing, in addition to the decorative seal.
