Description

[Technical Field]

[0001] The present invention relates to a drip rail boundary cover that covers the boundary between multiple drip rails arranged around the ceiling wall of a vehicle. [Background technology]

[0002] For example, gutter-shaped components called drip rails are sometimes arranged around the ceiling wall of a vehicle. These drip rails are intended to prevent rainwater and the like from running down onto the front door glass, rear window, etc. of the vehicle. Typically, multiple drip rails are prepared and arranged in a predetermined area around the ceiling wall of the vehicle, and the ends of adjacent drip rails are fixed to each other by welding or the like, or are arranged facing each other with a gap. However, weld marks are formed at the joints between the drip rails, and gaps are formed where the drip rails face each other, which can be unsightly. Therefore, covers are sometimes attached to cover the boundaries of such joints and gaps.

[0003] For example, Patent Document 1 below describes an automatic drip molding holder that includes a main body that can fit onto the molding side and the outside of the dripper wall, and a lower and upper pieces integrally molded from a synthetic resin with moderate elasticity. The lower piece has a fitting portion that fits onto an engaging protrusion on the lower flange of the molding and a fitting portion that fits onto an engaging step on the dripper. The upper piece has an engaging portion that engages with the upper flange of the molding, and a pressure-contact retaining piece that engages with a portion of the dripper with moderate pressure. The dripper has a base and a wall portion rising from the base. The fitting portion of the lower piece of the main body fits onto the lower end of the dripper wall, and the pressure-contact retaining portion of the upper piece of the main body engages with the upper end of the dripper wall while flexing and deforming, thereby sandwiching the dripper wall, thereby attaching the holder. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 58-79450 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, the holder in Patent Document 1 engages with the upper end of the dripper wall while the pressure-contact retaining portion of the main body flexes and deforms, so even if there is dimensional variation in the height of the dripper wall, the holder can be attached to the dripper wall to some extent. However, if the height of the dripper wall exceeds the deformability of the pressure-contact retaining portion of the main body and dimensional variation occurs, it becomes difficult to stably attach the holder to the dripper wall. Furthermore, because the holder is made of resin, it is prone to wear, raising concerns about whether it can be stably attached to the dripper wall over the long term.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a transition cover for a drip rail that can be stably attached to the drip rail over a long period of time. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a drip rail boundary cover that covers the boundary between multiple drip rails consisting of ribbed walls that are erected via concave grooves to surround the ceiling wall of a vehicle, and includes a metal spring member that is attached to the drip rail so as to cover the boundary, and a resin cover that is attached to cover the metal spring member, and the metal spring member has a spring body that is arranged to surround the ribbed wall from the outside, an insertion piece that extends from the lower end of the spring body, and a pressing piece that extends from the upper end of the spring body and abuts directly against the ceiling wall or abuts against a sealer attached to the ceiling wall, thereby clamping the drip rail between the lower end of the spring body and the resin cover, which has a cover body that extends along the outer periphery of the spring body, and an insertion portion provided on the lower end side of the cover body into which the insertion piece is inserted. [Effects of the Invention]

[0008] In the present invention, the pressing piece extending from the upper end of the spring body of the metal spring member abuts against the ceiling wall of the vehicle directly or against the sealer, and clamps the ceiling wall and drip rail between the lower end of the spring body. Therefore, by taking advantage of the large drip rail clamping force of the metal spring member and the resistance to sagging due to the resin material, the metal spring member can be stably attached to the drip rail over a long period of time, covering the boundaries between the drip rails.

DETAILED DESCRIPTION OF THE INVENTION

[0010] (One embodiment of a boundary cover for a drip rail) DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a drip rail cover according to the present invention will now be described with reference to the drawings.

[0011] 1 and 10, drip rail boundary cover 10 (hereinafter simply referred to as "rail cover 10") of this embodiment covers the boundary between multiple drip rails 2, 2 arranged to surround ceiling wall 1 of a vehicle, and includes metal spring member 20 attached to drip rail 2 so as to cover the boundary, and resin cover 40 attached so as to cover metal spring member 20. In this embodiment, gap 3 between drip rails 2, 2 corresponds to the "boundary" in the present invention.

[0012] As shown in Figure 1, each drip rail 2 extending to surround a ceiling wall 1 has a base plate 4 and a ribbed wall 6 erected from the outer edge of the base plate 4 via a recessed groove 5, forming a gutter-shaped rail. The base plate 4 of one drip rail 2 is placed on the base plate 4 of the other drip rail 2, creating a gap 3 between the ribbed wall 6 of one drip rail 2 and the ribbed wall 6 of the other drip rail 2. The ceiling wall 1 is placed on the base plate 4 of the other drip rail 2.

[0013] The rib-like wall 6 of each drip rail 2 has a slightly curved outer surface, and its lower end 6a is configured to protrude slightly downward relative to the base plate 4 due to the recessed groove 5, and this lower end 6a is adapted to engage with the lower end 25 of the metal spring member 20 (see FIG. 10). Note that the upper end 27 of the metal spring member 20 is disposed above the upper end 6b of the rib-like wall 6 (see FIG. 10).

[0014] First, the metal spring member 20 that constitutes the rail cover 10 will be described.

[0015] As shown in Figures 1 and 4, this metal spring member 20 is made by appropriately punching out and bending a metal plate material of a fixed thickness and a specified width, and has a spring body 21 arranged so as to surround the ribbed wall 6 of drip rail 2 from the outside, an insertion piece 29 extending from a lower end 25 of this spring body 21, and a pressing piece 33 extending from an upper end 27 of spring body 21 and abutting directly against the ceiling wall 1 of the vehicle or abutting against a sealer 7 attached to the ceiling wall 1, thereby clamping drip rail 2 between the lower end 25 of spring body 21 and the spring body 21.

[0016] In the following description, the "width direction" of the metal spring member 20 and the resin cover 40 means the direction along the extension direction of the drip rail 2 that extends along the periphery of the ceiling wall 1.

[0017] As shown in FIG. 4, spring body 21 extends in a gentle bow-like curve, and has a base 23 arranged on the outer surface side (the surface facing outward from the vehicle) of ribbed wall 6 of drip rail 2, a lower end 25 extending from lower end 23a of base 23 while curving downward in a convex shape and engaging with lower end 6a of ribbed wall 6, and an upper end 27 extending diagonally downward in a straight line via curved upper end 23b of base 23 and arranged above upper end 6b of ribbed wall 6, and when metal spring member 20 is viewed from the side as shown in FIG. 4, it has a shape that is bent in an approximately C-shape.

[0018] As shown in Fig. 1, the lower end 25 of the base 23 is formed so that its tip end in the extension direction is slightly narrower than the spring body 21, and is folded back in a mountain shape from the tip 25a in the extension direction, with an insertion piece 29 extending diagonally downward. This insertion piece 29 is a flat plate extending in a straight line, and has the same width as the tip end of the lower end 25 of the base 23, but is narrower than the rest of the lower end 25 of the base 23 (see Fig. 1). Furthermore, this insertion piece 29 is the part that is inserted (or can be said to be inserted) into an insertion hole 51 of the insertion portion 49 of the resin cover 40 (see Fig. 6).

[0019] 4, a support portion 31 is bent at a predetermined angle from a tip 27a in the extension direction of the upper end portion 27 of the base portion 23 relative to the upper end portion 27, and extends toward the tip 25a of the lower end portion 25. Similar to the insertion piece 29, the support portion 31 is a flat plate that extends linearly in a straight line.

[0020] 1 and 4, a pressing piece 33 is connected to the tip 31a of the support portion 31 in the extension direction, and is bent at a predetermined angle relative to the support portion 31. The base end 33a of the pressing piece 33 has the same width as the support portion 31 (see FIG. 1), and the portion other than the base end 33a is formed in a flat, long plate shape that is wider than the spring body 21 including the support portion 31. Also, as shown in FIG. 4, when the metal spring member 20 is viewed from the side, the tip of the pressing piece 33 extends so that it protrudes beyond the tip of the insertion piece 29. Furthermore, as shown in FIG. 10, in this embodiment, the tip of the lower surface of the pressing piece 33 is configured to abut against the sealer 7 attached to the ceiling wall 1.

[0021] 4, when the metal spring member 20 is viewed from the side, the pressing piece 33 is provided parallel to the upper end portion 27 of the spring body 21. That is, when the metal spring member 20 is viewed from the side as shown in FIG. 4, the metal spring member 20 has the upper end portion 27 and pressing piece 33 that are parallel to each other, and the support portion 31 that connects the upper end portion 27 and pressing piece 33 to each other, and the upper end portion 27, pressing piece 33, and support portion 31 form a substantially inverted Z shape when the metal spring member 20 is viewed from the side.

[0022] 4, the space between the pressing piece 33 and the insertion piece 29 forms an insertion hole 35, through which the ribbed wall 6 of the drip rail 2 is inserted (see FIG. 8). In this embodiment, the opening width of the insertion hole 35 is smaller than the total thickness of the base plate 4 of the drip rail 2, the ceiling wall 1 placed thereon, and the sealer 7 attached to the ceiling wall 1 (see FIG. 10).

[0023] As described above, the metal plate spring member 20 has a structure in which the pressure piece 33 is provided from the tip 27a of the upper end 27 of the base 23 via the linear support portion 31. Therefore, when attaching the rail cover 10 to the drip rail 2, it is mainly the base 23 including the lower end 25 and the upper end 27 that is prone to bending and deformation, while the support portion 31 and pressure piece 33 are less prone to bending and deformation (this will be explained in detail later).

[0024] The metal spring member 20 also has a retaining piece 37 that extends from at least one side of the pressing piece 33 toward the spring body 21 and is capable of coming into contact with the rib-like wall 6.

[0025] 1, a pair of retaining pieces 37, 37 formed in a long, thin strip shape on both widthwise sides of the pressing piece 33 and extending obliquely upward toward the base 23 of the spring body 21 via slits 37a, 37a from the base end 33a of the pressing piece 33. Also, as shown in FIG. 4, the retaining pieces 37 extend parallel to the surface of the pressing piece 33 and are parallel to the upper end 27 of the spring body 21 when the metal spring member 20 is viewed from the side.

[0026] As shown in Figures 10 and 11, when the rail cover 10 is attached to the drip rail 2, this anti-slip piece 37 is located on the inner surface of the ribbed wall 6 of the drip rail 2 (the surface opposite to the outer surface), and is configured to abut against the inner surface of the ribbed wall 6 when an external force acts on the rail cover 10 in a direction that causes it to come off the drip rail 2 (see the arrow in Figure 10).

[0027] The metal spring member 20 also has a positioning hole 39. In this embodiment, as shown in Fig. 1 and Fig. 6, the positioning hole 39 is formed in the widthwise central portion of the base 23, penetrating the base 23 from the upper end 23b side to the upper end 27. A positioning portion 62 of the resin cover 40 is inserted into the positioning hole 39 (see Fig. 6).

[0028] All of the components of the metal spring member 20 described above (spring body 21, base 23, lower end portion 25, upper end portion 27, insertion piece 29, support portion 31, pressing piece 33, retaining piece 37, etc.) are integrally formed. The metal spring member 20 can be manufactured by punching slits and holes of a predetermined shape into a metal plate made of a metal material such as S60C (carbon steel for mechanical structures), SK5 (carbon tool steel), or SUS304 (stainless steel), bending the metal plate, and then subjecting it to heat treatment to impart spring properties. However, the manufacturing method is not limited to this.

[0029] Next, the resin cover 40 attached to the metal spring member 20 will be described.

[0030] As shown in Figures 1 and 5, this resin cover 40 is made of synthetic resin material and has a cover body 41 that extends in an arched shape along at least the outer periphery of the spring body 21, and an insertion portion 49 provided on the lower end 45 side of this cover body 41 into which the insertion piece 29 is inserted.

[0031] As shown in Figure 5, the cover body 41 has a base 43 that extends in a gentle bow shape and is positioned outside the base 23 of the spring body 21, a lower end 45 that extends in a gentle curve from the lower end 43a of the base 43 and is positioned outside the lower end 25 of the spring body 21, and an upper end 47 that extends in a straight line diagonally downward from the upper end 43b of the base 43 and is positioned outside the upper end 27 of the spring body 21, and when viewed from the side, the resin cover 40 has a shape that is bent in an approximately C-shape.

[0032] An insertion portion 49 extends from a tip 45a of the lower end 45 of the cover body 41 in the extension direction in a direction away from the base 43. This insertion portion 49 has a thick portion 49a that protrudes toward the upper end 47 of the cover body 41 so as to be thicker than the lower end 45 of the cover body 41. As shown in FIGS. 3 and 6, this insertion portion 49 has an insertion hole 51 into which the insertion piece 29 of the metal spring member 20 is inserted (or can be said to be inserted). As shown in FIG. 6, this insertion hole 51 has a shape that penetrates the insertion portion 49 and its thick portion 49a obliquely downward. Furthermore, an inner surface 51a of the insertion hole 51 on the tip side in the extension direction is tapered, and the insertion piece 29 of the metal spring member 20 is engaged with this inner surface 51a. As shown in FIG. 5, when the resin cover 40 is viewed from the side, the tip of the insertion portion 49 extends so as to protrude beyond an upper end cover portion 53 described below.

[0033] Furthermore, as shown in FIG. 1, a recess 55 is provided on the upper end 47 side of the cover body 41, into which the spring body 21 and the base end 33a of the pressing piece 33 can be inserted when the metal spring member 20 and the resin cover 40 are attached.

[0034] That is, an upper end cover portion 53 extends from the tip 47a of the upper end portion 47 of the cover main body 41, via a portion having a curved outer surface, bent at a predetermined angle relative to the upper end portion 47, and toward the insertion portion 49 (see FIG. 4). As shown in FIG. 1, a pair of protrusions 54, 54 protrude downward on both sides of the width of the upper end cover portion 53, and the recess 55 is provided between these protrusions 54, 54. In other words, a pair of protrusions 54, 54 is disposed on both sides of the recess 55 in the width direction. The base 23 of the spring main body 21 can be inserted into this recess 55 when attaching the metal spring member 20 to the resin cover 40 or when attaching the rail cover 10 to the drip rail 2.

[0035] As shown in FIG. 5, an insertion port 56 is formed between the upper end cover portion 53 and the insertion portion 49, and the metal spring member 20 is inserted through this insertion port 56 (see FIG. 7).

[0036] Furthermore, the inner surface of the cover body 41 (the surface close to the outer surface of the metal spring member 20) is provided with abutment portions 57, 58, 59, and 60 which form protrusions extending in the width direction, and these abutment portions 57, 58, 59, and 60 are configured to abut against the outer periphery of the spring body 21 when the metal spring member 20 and the resin cover 40 are attached.

[0037] 5, (1) a first contact portion 57 is provided at a position on the lower end portion 45 of the cover body 41 near the lower end 43a of the base portion 43, (2) a second contact portion 58 is provided at a position between the lower end 43a and the upper end 43b of the base portion 43 of the cover body 41, (3) a third contact portion 59 is provided on the inner surface of the tip end 47a side of the upper end portion 47 of the cover body 41, and (4) a fourth contact portion 60 is provided on the inner surface of the upper end cover portion 53 of the cover body 41. In other words, the protruding contact portions are provided at two locations in the up-down direction of the cover body 41 (the third contact portion 59 and the first contact portion 57) and two locations in the front-rear direction (the fourth contact portion 60 and the second contact portion 58).

[0038] 1, each of the contact portions 57, 58, 59, and 60 extends like a protrusion from a position slightly inside the side edge of one widthwise side of the cover body 41 to a position slightly inside the side edge of the other widthwise side. As shown in FIG. 6, when the metal spring member 20 and the resin cover 40 are attached, the first contact portion 57 contacts the outer surface of the lower end portion 25 of the spring body 21, the second contact portion 58 contacts the outer surface of the base portion 23 of the spring body 21, the third contact portion 59 contacts the outer surface of the upper end portion 27 of the spring body 21, and the fourth contact portion 60 contacts the outer surface of the support portion 31 of the spring body 21.

[0039] Resin cover 40 also has a positioning portion 62 that protrudes from the inner surface of cover body 41 and is inserted through positioning hole 39 and inserted into the boundary between drip rails 2, 2 when metal spring member 20 is attached.

[0040] As shown in FIG. 5 , the positioning portion 62 in this embodiment is composed of a thin-walled plate-like rib 63 that protrudes from the center of the width of the cover body 41, extending from the inner surface of the upper end 43b of the base 43 to the inner surface of the upper end 47, and protrusions 64 that extend diagonally downward from the inner surface of the upper end 47 toward the base 43 and protrude from both sides of the rib 63 in the width direction. The rib 63 has a horizontal lower edge and a vertical front edge (the side away from the inner surface of the base 43) that can be inserted into the positioning hole 39 of the metal spring member 20 and the gap 3 between the drip rails 2, 2. The protrusions 64 are thicker than the rib 63 and have a dimension that approximately fits the width of the positioning hole 39 of the metal spring member 20. Both sides of the protrusion 64 are positioned adjacent to the inner periphery of the positioning hole 39 of the metal spring member 20, thereby suppressing rattle when the rail cover 10 is attached to the drip rail 2.

[0041] In addition, all of the components of the resin cover 40 described above (cover body 41, base 43, lower end 45, upper end 47, insertion portion 49, upper end cover portion 53, each abutment portion 57, 58, 59, 60, etc.) are integrally formed.

[0042] (Variation) The shapes and structures of the spring body, its base, lower end, upper end, insertion piece, pressing piece, anti-pullout piece, positioning hole, etc., which constitute the metal member in the embodiment described above, are not limited to the above-mentioned forms.

[0043] For example, in this embodiment, the spring body 21 has a substantially C-shaped bend when the metal spring member 20 is viewed from the side. However, the spring body may have a substantially U-shaped bend, as long as it can surround the rib-like wall 6 from the outside. Although the linear support portion 31 extends from the upper end portion 27 of the base portion 23, the support portion may have a curved shape. Furthermore, although a pair of retaining pieces 37, 37 extend from both widthwise ends of the pressing piece 33, the retaining piece may extend from only one widthwise side of the pressing piece. Furthermore, in this embodiment, the upper end portion 27 of the base portion 23 and the pressing piece 33 are parallel when the metal spring member 20 is viewed from the side. However, the two may be at different angles. Furthermore, although one positioning hole 39 is provided, two or more may be provided.

[0044] Furthermore, the shapes and structures of the cover body, its base, lower end, upper end, insertion portion, upper end cover portion, abutment portion, positioning portion, etc. that make up the resin cover are not limited to the above-mentioned aspects.

[0045] For example, in this embodiment, the cover body 41 has a shape that is bent into a substantially C-shape when the resin cover 40 is viewed from the side, but the cover body may also have a shape that is bent into a substantially U-shape, as long as it can surround the spring body of the metal spring member from the outside. Furthermore, the insertion hole 51 formed in the insertion portion 49 is a through-hole, but it may also be a recessed portion, a stepped portion, or the like, as long as it can insert and engage the insertion piece of the metal spring member. Furthermore, although the positioning portion 62 is shown as being one, two or more may be provided. Furthermore, although the abutment portions are shown as being four in total, two each in the vertical and front-to-rear directions, the number may be one to three, or five or more.

[0046] (Action and effect) Next, the effects of the rail cover 10 according to the present invention having the above-described structure will be described.

[0047] First, the process of attaching the metal spring member 20 and the resin cover 40 will be described with reference to FIG.

[0048] First, as shown in Fig. 7(a), the tip of the insertion piece 29 of the metal spring member 20 is inserted into the insertion hole 51 of the insertion portion 49 of the resin cover 40. In this state, the metal spring member 20 is rotated around the insertion piece 29 inserted into the insertion hole 51 as a fulcrum so that the base 23 of the metal spring member 20 approaches the base 43 of the resin cover 40. Then, as shown in Fig. 7(b), the spring body 21 of the metal spring member 20 enters through the insertion opening 56 of the resin cover 40 (see Fig. 5), and the upper end 23b and the upper end 27 of the base 23 of the metal spring member 20 pass through while being guided by the recess 55 of the upper end cover portion 53 of the resin cover 40 (while being guided by the pair of protrusions 54, 54).

[0049] When the metal spring member 20 is further rotated, as shown in FIG. 7(c), the inner surface of the recess 55 of the resin cover 40 is pressed against the upper end portion 27 of the metal spring member 20, causing the upper end portion 47 of the resin cover 40 to bend slightly (in this embodiment, as shown in FIG. 7(c), the upper end portion 47 of the resin cover 40 bends starting from a deformation point P1), and the metal spring member 20 penetrates deeper into the resin cover 40. Then, the support portion 31 of the metal spring member 20 passes, and the positioning portion 62 of the resin cover 40 is inserted into the positioning hole 39 of the metal spring member 20 and then removed from the positioning hole 39. As a result, the upper end portion 47 of the resin cover 40 elastically returns to its original state, and the contact portions 57, 58, 59, and 60 come into contact with predetermined locations on the spring main body 21. As a result, the metal spring member 20 and the resin cover 40 can be attached to each other, and the rail cover 10 can be assembled, as shown in FIG. 6.

[0050] Next, the mounting process for mounting the rail cover 10 to the drip rail 2 will be described with reference to FIGS.

[0051] First, the rail cover 10 is positioned so that it is located in the gap 3 between the drip rails 2, 2. Then, as shown in FIG. 8(a), the rail cover 10 is pushed toward the drip rail 2 so that the upper end 6b of the ribbed wall 6 of the drip rail 2 is inserted through the insertion opening 35 of the metal spring member 20. Then, as shown in FIG. 8(b), the tip of the insertion portion 49 of the resin cover 40 abuts against the outer surface of the ribbed wall 6, and the inner tip side of the pressing piece 33 of the metal spring member 20 abuts against the inner surface of the upper end 6b of the ribbed wall 6 and is pressed.

[0052] As the rail cover 10 is further pushed in, the tip of the insertion portion 49 of the resin cover 40 moves while abutting against the outer surface of the ribbed wall 6, and the tip of the pressing piece 33 of the metal spring member 20 abuts against and is pressed by the sealer 7, expanding the insertion opening 35 of the metal spring member 20 and the insertion opening 56 of the resin cover 40, and the rail cover 10 is attached to the ribbed wall 6 of the drip rail 2. Thereafter, as the rail cover 10 is further pushed in, as shown in Fig. 9, the tip of the insertion portion 49 of the resin cover 40 abuts against the lower end 6a of the ribbed wall 6, and the insertion portion 49, which has been abutted and pressed by the sealer 7, abuts against the lower end 6a of the ribbed wall 6, further expanding the insertion opening 35 of the metal spring member 20 and the insertion opening 56 of the resin cover 40.

[0053] Furthermore, as described above, when the insertion opening 35 of the metal spring member 20 and the insertion opening 56 of the resin cover 40 are pushed open during the installation of the rail cover 10 on the drip rail 2, the base 23 of the metal spring member 20 and the base 43 of the resin cover 40 are mainly slightly flexed and deformed (in this embodiment, as shown in FIG. 9, the base 23 of the metal spring member 20 flexes and deforms starting from a deformation point P2 located near the lower end 23a, and the base 43 of the resin cover 40 flexes and deforms starting from a deformation point P2 located near the lower end 43a).

[0054] 10 , when the insertion portion 49 of the resin cover 40 moves over the lower end portion 6a of the ribbed wall 6 and the retaining piece 37 of the metal spring member 20 moves over the upper end portion 6b of the ribbed wall 6, the base portion 23 of the metal spring member 20 and the base portion 43 of the resin cover 40 elastically return to their original position. As a result, the insertion piece 29 inserted into the insertion portion 49 engages with the lower end portion 6a of the ribbed wall 6 and the pressing piece 33 abuts against the sealer 7, so that the metal spring member 20 sandwiches the ceiling wall 1 and the drip rail 2 to which the sealer 7 is attached. As a result, the rail cover 10 can be attached to the drip rails 2, 2 so as to cover the gap 3 between the drip rails 2, 2.

[0055] As described above, in this rail cover 10, the pressing piece 33 extending from the upper end 27 of the spring body 21 of the metal spring member 20 abuts against the sealer 7, sandwiching the ceiling wall 1 and the drip rail 2 between the lower end 25 of the spring body 21. This allows the metal spring member 20 to be stably attached to the drip rail 2 over a long period of time, covering the boundary (gap 3 in this case) between the drip rails 2, 2, by utilizing its greater drip rail clamping force (force that clamps the drip rail) than a resin material and its resistance to sagging compared to a resin material. Furthermore, the resin cover 40 is attached to further cover the metal spring member 20 that covers the gap 3 between the drip rails 2, 2, making it impossible to see the boundary between the drip rails 2, 2 and the metal spring member 20, improving the appearance.

[0056] Furthermore, when attaching the metal spring member 20 to the resin cover 40, as described above, the insertion pieces 29 of the metal spring member 20 are inserted into the insertion portions 49 of the resin cover 40 (here, inserted into the insertion holes 51 of the insertion portions 49), and the spring body 21 is rotated so as to approach the inner periphery of the cover body 41, thereby causing the spring body 21 and the cover body 41 to bend and move into the inner periphery of the cover body 41, thereby attaching the metal spring member 20 to the resin cover 40 (see FIGS. 6 and 7). In this way, by simply inserting the insertion pieces 29 of the metal spring member 20 into the insertion portions 49 of the resin cover 40 and rotating the spring body 21 so as to approach the inner periphery of the cover body 41, the cover body 41 is disposed on the outer periphery of the spring body 21, and the resin cover 40 can be easily attached to the metal spring member 20.

[0057] When viewed from the side, metal spring member 20 has a generally inverted Z-shape (see FIG. 3 ), and support portion 31 supporting pressing piece 33 is linear. This allows support portion 31 to be as long as possible and facilitates the withstanding of pressing force from sealer 7 or ceiling wall 1 acting on pressing piece 33 when rail cover 10 is attached to drip rail 2. As a result, when rail cover 10 is attached to drip rail 2 and pressing piece 33 is pressed by sealer 7 or the like, support portion 31 is made less susceptible to bending deformation, while base portion 23 to which support portion 31 is connected is made more susceptible to bending deformation (see FIG. 9 ). Furthermore, because support portion 31 is linear and its length is easily ensured, pressing force from sealer 7 acting on pressing piece 33 supported by support portion 31 when rail cover 10 is attached to drip rail 2 can be easily withstood.

[0058] 4, if the portion supporting the retaining piece 33 were an arc-shaped support portion 31' rather than a linear support portion 31, it would be difficult to ensure its length. Furthermore, when the rail cover 10 is attached to the drip rail 2, if the retaining piece 33 is pressed by the sealer 7 or the like, the pressing force would be difficult to withstand. Therefore, the entire arc-shaped support portion 31' would be more likely to flex and deform, while the base 23 would be less likely to flex and deform. As a result, the insertion opening 35 of the metal elastic spring member 20 would be more difficult to expand, making it difficult to attach the rail cover 10 to the drip rail 2.

[0059] In contrast, in the case of this embodiment, as described above, metal spring member 20 has a generally inverted Z shape when viewed from the side (see FIG. 3), and support portion 31 that supports pressure piece 33 is linear, so that pressure piece 33 is more likely to bend and deform on the base 23 side than on the support portion 31 side. Therefore, when attaching rail cover 10 to drip rail 2, the upper end of drip rail 2 can be relatively easily inserted and pushed in through insertion port 35 between lower end 25 of metal spring member 20 and pressure piece 33, improving the ease of attaching drip rail 2 to rail cover 10.

[0060] In addition, in this embodiment, the metal spring member 20 has a retaining piece 37 that extends from at least one side of the pressing piece toward the spring body 21 and is capable of abutting against the rib-shaped wall 6 (see Figure 1).

[0061] According to the above embodiment, as shown by the arrow in FIG. 10 , when an external force acts on metal spring member 20 such that it comes off drip rail 2, retaining piece 37 comes into contact with drip rail 2, preventing metal spring member 20 from coming off drip rail 2, and allowing rail cover 10 to be stably attached to drip rail 2.

[0062] Furthermore, in this embodiment, as shown in Figures 1 and 6, the spring body 21 has a positioning hole 39, and the resin cover 40 has a positioning portion 62 that protrudes from the inner surface of the cover body 41 and is inserted through the positioning hole 39 and inserted into the boundary when attached to the metal spring member 20.

[0063] According to the above embodiment, as shown in FIG. 6, when resin cover 40 is attached to metal spring member 20, positioning portion 62 of resin cover 40 is inserted through positioning hole 39 of spring body 41, and this positioning portion 62 enters the joint (here, gap 3). Therefore, resin cover 40 and metal spring member 20 via resin cover 40 can be attached to the joint between drip rails 2, 2 while suppressing misalignment.

[0064] Furthermore, when the metal spring member 20 and the resin cover 40 are attached, the positioning portion 62 of the resin cover 40 is inserted into the positioning hole 39 of the metal spring member 20, thereby suppressing misalignment between the metal spring member 20 and the resin cover 40, and allowing the resin cover 40 to be stably attached to the metal spring member 20.

[0065] In this embodiment, the cover body 41 is provided on the upper end 47 side with a recess 55 into which the spring body 41 can be inserted when the metal spring member 20 and the resin cover 40 are attached.

[0066] According to the above embodiment, when inserting the insertion piece 29 of the metal spring member 20 into the insertion portion 49 of the resin cover 40 to attach the metal spring member 20 to the resin cover 40 and rotating the spring body 21 so that it approaches the inner circumference of the cover body 41, the spring body 21 can be inserted into the recess 55 provided on the upper end portion 47 side of the cover body 41 and rotated while being guided, thereby improving the ease of attaching the metal spring member 20 to the resin cover 40.

[0067] Furthermore, in this embodiment, the inner surface of the cover body 41 is provided with abutment portions 57, 58, 59, and 60 that form protrusions extending in the width direction, and the abutment portions 57, 58, 59, and 60 are configured to abut against the outer periphery of the spring body 21 when the metal spring member 20 and the resin cover 40 are attached (see Figure 6).

[0068] According to the above aspect, when the metal spring member 20 and the resin cover 40 are attached, the abutment portions 57, 58, 59, and 60 forming the protrusions of the cover body 41 abut against the outer periphery of the spring body 21, thereby enabling the metal spring member 20 and the resin cover 40 to be attached while suppressing rattle. In this embodiment, the abutment portions are provided at two locations on the cover body 41 in the up-down direction (the third abutment portion 59 and the first abutment portion 57) and two locations in the front-rear direction (the fourth abutment portion 60 and the second abutment portion 58), thereby suppressing rattle in the up-down direction and the front-rear direction. Furthermore, the abutment portions 57, 58, 59, and 60 form protrusions extending in the width direction of the cover body 41 and are provided partially on the cover body 41. This reduces the overall thickness of the cover body 41, facilitating flexural deformation, thereby facilitating attachment of the resin cover 40 to the metal spring member 20.

[0069] (Another embodiment of a drip rail boundary cover) 12 to 16 show another embodiment of the drip rail boundary cover according to the present invention. Note that parts that are essentially the same as those in the above embodiment are given the same reference numerals and their description will be omitted.

[0070] As shown in Figures 12 and 13, the drip rail boundary cover 10A of this embodiment (hereinafter also simply referred to as "rail cover 10A") has a metal spring member 20A and a resin cover 40A, similar to the rail cover 10 of the previous embodiment.

[0071] First, the metal spring member 20A will be described.

[0072] The metal spring member 20A in this embodiment has a structure having a pair of retaining pieces 37A, 37A on both widthwise sides of the pressing piece 33, similar to the metal spring member 20 in the above embodiment, but the shape of each retaining piece 37A is different from that of the retaining piece 37 in the above embodiment. That is, the retaining piece 37A in this embodiment has a tip end 38c in the extension direction that is bent so as to be able to abut against the rib-like wall 6.

[0073] More specifically, each retaining piece 37A has a base portion 38a extending straight toward the spring main body 21, and a tip portion 38c bent from the tip of the extending direction of the base portion 38a via an R-shaped bent portion 38b (hereinafter also simply referred to as "bent portion 38b") so as to face the upper end portion 27 side of the base portion 23 of the spring main body 21. Note that bent portion 38b forms a part of tip portion 38c, and it can also be said that tip portion 38c has bent portion 38b.

[0074] When the rail cover 10A is attached to the drip rail 2, the inner surface of the tip 38c of the anti-slip piece 37A (the surface close to the inner surface of the base 23 of the spring body 21) and the bent portion 38b (bent portion 38b) can abut against the ribbed wall 6.

[0075] That is, when rail cover 10 is pushed toward drip rail 2 so that upper end 6b of ribbed wall 6 of drip rail 2 is inserted through insertion opening 35 of metal spring member 20A constituting rail cover 10A, insertion opening 35 of metal spring member 20A and insertion opening 56 of resin cover 40A are pushed apart, and rail cover 10A is attached to ribbed wall 6. During this process, base 38a of retaining piece 37A slides against upper end 6b of ribbed wall 6, and then tip 38c attempts to climb over upper end 6b of ribbed wall 6. At this time, the inner surface and bent portion 38b of tip 38c of retaining piece 37A abut against upper end 6b of ribbed wall 6. Therefore, the tip edge of retaining piece 37A in the extending direction, i.e., the edge of tip 38c, does not abut against ribbed wall 6.

[0076] In addition, the upper end 27 of the spring body 21 of the metal spring member 20A is provided with a spring-side bent portion that is bent so as to be positioned inside the rib-shaped wall 6, and a rib engagement hole 32 is formed in the spring-side bent portion.

[0077] That is, the upper end 27 of the base 23 constituting the spring body 21 has a support portion 31 that extends from a tip 27a in the extension direction, bending at a predetermined angle relative to the upper end 27, and this support portion 31 forms the above-mentioned "spring-side bent portion." A rib locking hole 32 is formed in the center in the width direction of the support portion 31 that forms the spring-side bent portion. In this embodiment, as shown in Figures 12 and 15, the rib locking hole 32 is formed in a substantially L-shape that extends from the support portion 31 that forms the spring-side bent portion to the base end 33a of the pressing piece 33 that is bent and connected to the support portion 31.

[0078] A locking rib 65 (see FIGS. 14 and 15), which will be described later, of the resin cover 40A can be locked onto the upper edge 32a of this rib locking hole 32. Note that the rib locking hole may be provided in the spring-side bent portion of the upper end of the spring body, and may have any upper edge that allows the locking rib to be locked onto it; for example, the rib locking hole may be formed only in the support portion that forms the spring-side bent portion.

[0079] Next, the resin cover 40A will be described.

[0080] 14 and 15, the resin cover 40A in this embodiment has a cover main body 41, and this cover main body 41 is provided with a locking rib 65 that fits into a rib locking hole 32 provided in the spring-side bent portion of the metal spring member 20A and can be locked to the upper edge 32a of the rib locking hole 32. In this embodiment, the locking rib 65 having a substantially triangular projection shape protrudes from the widthwise center of a fourth abutment portion 60 that protrudes from the inner surface of the upper-end cover portion 53 of the cover main body 41.

[0081] During the process of attaching the metal spring member 20A and the resin cover 40A, the top 65a of this locking rib 65 is pressed against the upper end portion 27 and support portion 31 of the spring body 21 of the metal spring member 20A, while sliding against the outer surfaces of the upper end portion 27 of the spring body 21 and support portion 31. When the locking rib 65 reaches the rib locking hole 32, the locking rib 65 enters through the front opening of the rib locking hole 32 and can be locked onto the upper edge 32a of the rib locking hole 32.

[0082] The locking rib may be, for example, a circular protrusion or a trapezoidal protrusion, as long as it can be locked onto the upper edge of the rib locking hole. In this embodiment, the locking rib 65 indirectly protrudes from the inner surface of the upper end cover portion 53 of the cover main body 41 via the fourth abutment portion 60, but if the fourth abutment portion 60 is not provided, the locking rib may protrude directly from the inner surface of the upper end cover portion 53.

[0083] The inner surface of the cover body 41 is provided with a plurality of contact portions 57, 58, 59, and 60 each forming a ridge extending in the width direction, and in this embodiment, one more contact portion is also provided: a fifth contact portion 61. That is, as shown in Fig. 15, the inner surface of the cover body 41 is provided with a first contact portion 57 at a position on the lower end portion 45 near the lower end 43a of the base 43, and a second contact portion 58 between the lower end 43a and the upper end 43b of the base 43, and the fifth contact portion 61 is provided between the first contact portion 57 and the second contact portion 58. Here, the fifth contact portion 61 forming a ridge is provided on the inner surface of the cover body 41 in a position close to the lower end 43a of the base 43 and extending in the width direction.

[0084] Furthermore, in this embodiment, an R-shaped portion 50 having a curved surface formed with a predetermined curvature is provided at the inner corner on the base end side (the end side close to the cover body 41) of the thick portion 49a of the insertion portion 49. That is, the inner corner on the base end side of the thick portion 49a of the insertion portion 49 does not have a sharp edge or corner shape as in the embodiment shown in Fig. 5, but has a curved surface due to the R-shaped portion 50.

[0085] (Action and effect) Next, the effects of the rail cover 10A according to the present invention having the above-described structure will be described.

[0086] First, the effect of attaching the metal spring member 20A to the resin cover 40A will be described. That is, after inserting the tip of the insertion piece 29 of the metal spring member 20A into the insertion hole 51 of the insertion portion 49 of the resin cover 40A, the metal spring member 20A is rotated around the insertion piece 29 as a fulcrum so that the base 23 of the metal spring member 20A approaches the base 43 of the resin cover 40A. Then, the inner surface of the recess 55 of the resin cover 40A is pressed against the upper end 27 of the metal spring member 20A, and then the top 65a of the locking rib 65 of the resin cover 40A is pressed against the upper end 27 of the metal spring member 20A and the support portion 31 (at this time, the top 65a of the locking rib 65 slides against the upper end 27 of the spring body 21 and the outer surface of the support portion 31), causing the upper end 47 of the resin cover 40A to bend slightly, and the metal spring member 20A penetrates deeper into the resin cover 40A. Then, when the positioning portion 62 of the resin cover 40A reaches the positioning hole 39 of the metal spring member 20A and the locking rib 65 reaches the rib locking hole 32, the upper end portion 47 of the resin cover 40A elastically returns, the positioning portion 62 enters the positioning hole 39, and the locking rib 65 enters the rib locking hole 32, and further the abutment portions 57, 58, 59, 60, and 61 abut against predetermined locations on the spring main body 21. As a result, as shown in Fig. 15, the metal spring member 20A and the resin cover 40A can be attached and the rail cover 10A can be assembled.

[0087] In this embodiment, when the locking rib 65 of the resin cover 40A, which has been in sliding contact with the upper end 27 of the spring body 21 and the outer surface of the support portion 31, reaches the rib locking hole 32 of the metal spring member 20A, the upper end 27 of the resin cover 40A, which has been bent and deformed, elastically returns to its original state, and the locking rib 65 enters the rib locking hole 32. Therefore, a clicking sensation (a click sensation) can be felt when the locking rib 65 is inserted into the rib locking hole 32, so that the user can reliably know that the installation of the metal spring member 20A and the resin cover 40A has been completed.

[0088] This embodiment is also effective when attaching the rail cover 10A to the drip rail 2.

[0089] That is, while rail cover 10A is being pushed toward drip rail 2 so that upper end 6b of ribbed wall 6 of drip rail 2 is inserted through insertion port 35 of metal spring member 20A, retaining piece 37A of metal spring member 20A is pushed in so that base 38a thereof is in sliding contact with upper end 6b of ribbed wall 6. As rail cover 10A is further pushed in and tip end 38c of retaining piece 37A attempts to climb over upper end 6b of ribbed wall 6, the inner surface and bent portion 38b of tip end 38c climb over (pass through) while abutting against upper end 6b of ribbed wall 6. Therefore, the tip edge of retaining piece 37A in the extending direction, i.e., the edge of tip end 38c, does not abut against upper end 6b of ribbed wall 6. After that, when the rail cover 10A is further pushed in and the tip 38c of the anti-slip piece 37A passes over the upper end 6b of the ribbed wall 6, the pressing piece 33 abuts against the sealer 7, as shown in Figure 16, and the metal spring member 20A clamps the ceiling wall 1 and drip rail 2 to which the sealer 7 is attached, and the rail cover 10A is attached to the drip rails 2, 2.

[0090] In this embodiment, in order to attach rail cover 10A to the boundary between drip rails 2, 2, rail cover 10A is pushed toward drip rail 2, and when tip 38c of anti-slip piece 37A passes over upper end 6b of ribbed wall 6, the inner surface and bent portion 38b of tip 38c of anti-slip piece 37A can abut against upper end 6b of ribbed wall 6.

[0091] This prevents edges or burrs, such as the leading edge of retaining piece 37A in the extension direction (the most extreme edge of leading end 38c), from abutting against upper end 6b of ribbed wall 6. As a result, when rail cover 10A is attached to the boundary between drip rails 2, 2, it is possible to prevent upper end 6b of ribbed wall 6 from being scraped by the leading edge of retaining piece 37A, thereby preventing paint peeling and the like.

[0092] Also, in this embodiment, as shown in Figure 15, the upper end 27 of the spring body 21 is provided with a spring-side bent portion that is bent so as to be positioned inside the ribbed wall 6, and a rib locking hole 32 is formed in the spring-side bent portion, and the cover body 41 is provided with a locking rib 65 that fits into the rib locking hole 32 and can be locked to the upper edge 32a of the rib locking hole 32.

[0093] Therefore, when rail cover 10A is attached to the boundary between drip rails 2, 2 (see FIG. 16), as shown by the arrow in FIG. 16, when an external force directed outward from ribbed wall 6 (including lateral and oblique external forces in the direction of the arrow in FIG. 16) acts on upper end 47 of cover body 41, locking rib 65 provided on cover body 41 locks with upper edge 32a of rib locking hole 32 of spring body 21, thereby reliably maintaining the attachment state between metal spring member 20A and resin cover 40A. In other words, it is possible to reliably prevent resin cover 40A from coming off metal spring member 20A.

[0094] Furthermore, in this embodiment, the inner surface of the cover body 41 is provided with a first abutment portion 57 located at a position on the lower end portion 45 near the lower end 43a of the base 43, and a second abutment portion 58 located between the lower end 43a and the upper end 43b of the base 43, as well as a fifth abutment portion 61 located between the first abutment portion 57 and the second abutment portion 58 (see Figure 16).

[0095] According to this embodiment, during the process of attaching the metal spring member 20A and the resin cover 40A, even if the base 23 of the spring body 21 attempts to enter between the first abutment portion 57 and the second abutment portion 58 on the inner surface of the cover body 41 (see the arrows in FIG. 15 ), the base 23 of the spring body 21 abuts against the fifth abutment portion 61, and therefore the base 23 of the spring body 21 can be prevented from entering between the first abutment portion 57 and the second abutment portion 58. As a result, the insertion amount of the insertion piece 29 of the metal spring member 20A into the insertion hole 51 of the resin cover 40A is maintained, and the engagement allowance of the insertion piece 29 with the insertion hole 51 can be maintained, so the attached state of the metal spring member 20A and the resin cover 40A is maintained, and it is possible to reliably prevent the resin cover 40A from coming off the metal spring member 20A.

[0096] In this embodiment, an R-shaped portion 50 having a curved surface formed at a predetermined curvature is provided at the inner corner of the base end side of the thick portion 49a of the insertion portion 49.

[0097] According to this embodiment, when rail cover 10A is attached to the boundary between drip rails 2, 2 (see Figure 16), even if R-shaped portion 50 of thick portion 49a of insertion portion 49 of resin cover 40A abuts against lower end portion 6a of ribbed wall 6 or the back side of base plate 4 of drip rail 2, etc., R-shaped portion 50 has a curved surface shape, so that stress concentration on those parts can be alleviated, thereby preventing problems such as corrosion and paint peeling.

[0098] It should be noted that the present invention is not limited to the above-described embodiment, and various modified embodiments are possible within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention.
