The cut-and-raised piece 12d is fitted at an acute angle with the shaft portion 21a of the bolt body 21, but the inwardly raised piece 12 itself is inclined. Depending on the degree of the inclination, the cut-and-raised piece 12d is cut and raised. The piece 12d may not be formed. Furthermore, a rib 12e for increasing the strength of the inward flange 12 is formed on the inward flange 12.

  Furthermore, the mounting structure of the on-roof mounting tool 10 of the present embodiment has a structure in which a spacer member S is further added. The spacer member S is a hollow pedestal 40 made of an annular pedestal 47 for mounting the roof mounting fixture 10. The bent base portion 12 a of the inward flange 12 abuts against the upper end surface 47 a, and the nut 22 and the washer 23. Is placed on the top surface of the top portion 31a of the folded-plate roof 30 so as to surround the whole and hide in the hollow portion 48. The base ring 47 may be lower than the upper end of the nut 22.

  The roof fixture 10 configured as described above is used by being attached to the folded plate roof 30 in the following manner.

  First, after passing the shaft portion 13a of the tightening bolt 13 from one of the shaft holes 11ba of the both leg pieces 11b, 11b of the roof mounting fixture 10, the tightening nut 14 is lightly tightened from the tip side of the tightening bolt 13. Set temporarily.

  Next, from above the bolt body 21 protruding from the top portion 31a of the folded plate roof 30, the annular spacer member S (the wheel 47) is first folded so that the bolt body 21 is inserted into the hollow portion 48. It is placed on the upper surface of the top portion 31a of the plate roof 30, and then the roof mounting fixture 10 is placed on the upper end surface 47a of the base ring 47 so that the bolt body 21 is fitted in the gap 15 between the leg pieces 11b, 11b. It is mounted (see FIGS. 3A and 3B).

  Then, when the tightening bolt 13 and the tightening nut 14 that have been temporarily fixed are tightened, both the leg pieces 11b and 11b are brought close to each other by the tightening force, and the both inward flange pieces 12 and 12 at the lower ends of the both leg pieces 11b and 11b are also formed. The gaps 15 are close to each other so that the gap 15 is small, and both recesses 12c and 12c of the inwardly facing flange pieces 12 and 12 sandwich the shaft portion 21a of the bolt body 21, and the cut and raised piece 12d is a thread groove of the bolt body 21. The two are firmly connected and fixed (see FIG. 1).

  Various devices and members (not shown) can be attached on the main body 11 of the rooftop fixture 10 attached to the folded plate roof 30 in this manner.

In the state where the was tightened legs pieces 11b, 11b2 in tightening bolt 13 and tightening nut 14, FIG. 1 (a), the legs pieces 11b, both leg pieces 11b the lower end of 11b are approaching each other, 11b changes from the inclined state to the substantially vertical state, and the bent base portion 12a, which is the lower end portion thereof, approaches each other and is stably placed on the pedestal 47.

  In this way, according to the structure in which the hollow pedestal 40 made of the pedestal 47 is provided, the inwardly facing piece 12 does not float from the top portion 31a, and the on-roof fixture 10 is not spaced from the folded roof 30. It can be attached stably and firmly. Further, since the base wheel 47 is provided, the seesaw-like wobble can be prevented.

  Further, since the spacer member S is constituted by the base ring 47, the spacer member S can be stably placed on the top portion 31a so as not to touch the washer 23, and can also contribute to saving of the material amount. Since it covers from the side, there is no gap and it looks good.

  Moreover, in this embodiment, since the bolt body 21 for attaching the on-roof fixture 10 to the folded plate roof 30 is also used for roof material connection, the number of members for attachment may be reduced. it can.

  In the above, the hollow pedestal 40 (the pedestal 47) that is annular and does not have a seat plate is shown as an example of the spacer member S. However, the hollow pedestal 40 as shown in FIGS. Also good. In FIG. 4 (a), the folded plate roof to which the on-roof fixture is attached is schematically shown, and in FIGS. 4 (b) and 4 (c), illustration thereof is omitted.

  The hollow pedestal 40 shown in FIG. 4 (a) is a rectangular pedestal 47 in plan view with a part cut away, and the pedestal 47 has a shape in which the lower end portion is placed on the top 31a with the washer 23 being displaced. It has become. A broken line in FIG. 4A indicates a mounting position on the top portion 31 a of the base wheel 47.

  According to this hollow pedestal 40, since it is constituted by the pedestal 47, the roof mounting fixture 10 can be stably supported, and a part is notched and the shape of the washer 23 is not hidden. Can be reduced. Further, it can be easily formed by bending without using molding.

  The hollow pedestal 40 shown in FIG. 4B includes a rectangular seat plate 41 having a through hole 43 of the bolt body 21 and L-shaped leg portions 42 extending downward from both short edges thereof. ing. The leg portions 42 are placed on the top portion 31a so as to be arranged side by side along the forming direction of the top portion 31a. 4B and 4C, the installation direction of the spacer member S with respect to the folded plate roof 30 is the same as that in FIG. 4A.

  Further, the hollow pedestal 40 shown in FIG. 4 (c) includes a rectangular seat plate 41 having a through hole 43 as in FIG. 4 (b), but the leg portion 42 has a wave of the top portion 31a. It is formed on both long side edges of the seat plate 41 arranged along the direction. The leg portion 42 is notched at the center so as not to touch the washer 23.

  4B and 4C, the through hole 43 has a diameter slightly larger than that of the nut 22 and the hollow base 40 in which the upper end of the nut 22 protrudes slightly from the through hole 43 is shown. May be concealed below the seat plate 41. Of course, as shown in the figure, the through hole 43 through which the nut 22 can be passed and the seat plate 41 of the hollow pedestal 40 is formed low so that the clamping position of the inward flange 12 on the bolt body 21 can be lowered and stabilized. It can be desirable.

  In all of the above three examples, the spacer member S is mounted and supported on the top 31a of the folded plate roof 30 and has a pedestal structure that supports the on-roof fixture 10 as shown in FIG. The roof mounting fixture 10 can be stably and firmly attached to the folded plate roof 30 without a gap. In particular, since all of the spacer members S shown in FIGS. 1 to 4 have the structure of the hollow pedestal 40, they can be placed on the top surface of the top portion 31 a without touching the washer 23.

  As a spacer member comprised by the hollow base, the structure which added the bottom plate part with a through-hole or / and the top plate part with a through-hole to the circular or rectangular base ring may be sufficient.

  Next, a second embodiment of the present invention will be described.

  FIG. 5 is an exploded perspective view showing the mounting structure of the roof mounting tool of the second embodiment, and FIG. 6 is a perspective view after the roof mounting tool is mounted.

  In the description of FIG. 5 and FIG. 6, the same reference numerals are given to the same parts as those in FIG. 1 to FIG. 4 (first embodiment), the overlapping description is omitted, and only the feature points are described. And

  In the present embodiment, the spacer member S is a structure of the hollow pedestal 40, that is, a structure in which the washer 23 is placed and supported on the top 31 a of the folded plate roof 30, and the roof mounting fixture 10 is supported by the seat plate 41. In that respect, it is the same as that of the first embodiment (the configuration having the seat plate and the legs in FIGS. 4B and 4C), but protrudes above both edges of the seat plate 41. This embodiment differs from that of the first embodiment in that it includes a mounting member detent piece 44 and spacer member detent pieces 45 provided at both ends of a leg 42 extending downward from the other edges. . In the illustrated example, the through hole 43 is formed in a hole larger than the nut 22 so that the nut 22 protrudes upward, but the nut 22 may be concealed below the seat plate 41.

  When the on-roof fixture 30 is attached, the fixture detent piece 44 is in contact with or in close proximity to both side ends of the inwardly facing lug 12 and is attached even if a rotational force acts on the on-roof fixture 10. Since it is locked to the anti-rotation piece 44, it is possible to prevent rotational deviation and to prevent the gap 15 between the inward flange pieces 12 from shifting in the longitudinal direction. In addition, you may provide the fixture anti-rotation piece 44 in the same side as the leg part 42. FIG.

  The spacer member detent pieces 45 are formed in pairs on both leg portions 42, and each pair of leg portions 42 has a pair of spacer member detent pieces 45 on the top portion 31 a of the mountain portion 31 of the folded plate roof 30. Since it is placed on the top 31a so as to straddle, the rotation of the spacer member S and the movement in the wave direction can be restrained.

  Needless to say, the movement of the spacer member S in the wave direction and the movement of the top portion 31 a in the forming direction are also regulated by the nut 22 or the bolt body 21 inserted through the through hole 43. Therefore, the spacer member S does not move unless the nut 22 or the bolt body 21 is removed.

  Further, since the spacer member S shown in FIGS. 5 and 6 can be formed by cutting and raising, bending, etc., it is easy to manufacture.

  FIGS. 7A and 7B are perspective views showing other two examples of the spacer member related to both the embodiment and the third embodiment.

  These spacer members S have a pedestal structure provided with a seat plate 41 and leg portions 42, and are further provided with a fixture anti-rotation piece 44 and a spacer member anti-rotation piece 45 as shown in FIGS. Is similar. However, in FIGS. 7A and 7B, the leg portion 42 is formed only on one side, and the lower surface of the seat plate 41 is attached to the nut 22 when installed on the top portion 31 a of the folded roof 30. Supported in contact. That is, the spacer member S is the same type as a support plate 50 (see FIG. 8) described later, and can be said to have a configuration in which legs are further added to the support plate 50.

  That is, these spacer members S are supported from below at one portion of the leg portion 42 and the contact portion of the seat plate 41 with the nut 22, so that the spacer member S and the roof mounting thereon are provided. The tool 10 is stable without wobbling.

  Further, since the spacer member S is formed with the attachment member detent piece 44 and the spacer member detent piece 45, the spacer member S and the roof fixture 10 can be prevented from being rotated.

  In addition, the spacer member S shown in FIG. 7B is provided with attachment fixture detent pieces 44 constituted by small protrusions protruding upward at four locations on the upper surface of the seat plate 41.

  7 (a) and 7 (b), the leg portion 42 does not contact the top surface of the top portion 31a (see FIG. 6) of the folded plate roof 30, that is, has a structure that is in a floating state. Good. The spacer member having such a structure is positioned as equivalent to the support plate 50 (see FIG. 8) in the third embodiment described below, rather than the hollow pedestal. Moreover, the structure where the edge part 45a which the two spacer member detent | locking pieces 45 opposes contacts the edge part of the top part 31a may be sufficient.

Next, a third embodiment (reference example) of the present invention will be described. In the present embodiment and the fourth and fifth embodiments, a structure using a spacer member that does not come into contact with the folded plate roof when the on-roof fixture is attached to the folded plate roof is shown.

For example, a flat plate-like support plate having a through-hole (a through-hole having a larger diameter than the support plate 50 shown in FIGS. 8 and 9) can be used.

  Thus, the support plate 50 that is placed in contact with the washer 23 and has the through hole 51 that penetrates the nut 22 can be used effectively for the nut 22 and the washer 23 that are integrated with each other. According to the present invention, since the height position of the on-roof fixture 10 can be lowered, even if the inward flange 12 is steep or the shaft 21a of the bolt body 21 is short, the tip of the inward flange 12 12b can be clamped to the bolt body 21.

  In the structure shown in FIG. 13, the spacer member S is composed of a support plate 50, and the support plate 50 is supported in a state sandwiched between a washer 23 and a nut 22. Further, the support plate 50 supports the on-roof fixture 10 by contacting the bent base portion 12a of the inwardly facing flange 12 on the upper surface.

  Since the spacer member S is firmly screwed between the bolt body 21 and the nut 22 so as to be firmly sandwiched between them, the spacer member S can be prevented from rotating. Further, since the support plate 50 is arranged under the nut 22 and the bent base 12a of the inwardly facing piece 12 of the roof mounting fixture 10 is configured to contact the support plate 50 arranged below, the inward Even if the flange 12 has a steep slope or the shaft 21 a of the bolt body 21 is short, the tip 12 b of the inward flange 12 can be clamped to the bolt body 21.

  In the various embodiments described above, the waterproof washer 23 is disposed between the top portion 31a of the folded plate roof 30 and the nut 22, but for the first to fourth embodiments, The present invention can also be applied to a folded plate roof provided with a waterproof packing instead of the waterproof washer 23.

  Further, in the above-described various embodiments, for the example having the through hole 51 that allows the bolt body 21 to pass therethrough (see FIGS. 8 and 10C), a female screw (screw groove) is formed in the through hole 51. You may let them. In that case, if the seat plate and the support plate of the pedestal are rectangular, it may be impossible to align the top of the folded plate roof 30 on the top 31a if it is to be screwed.
