<Prior Art> A spoiler fixed on the rear part of a vehicle body of an automobile is elongated in the width direction of the vehicle body and has a plurality of mounting legs facing downward, and a bolt integrally projects downward from the lower surface of each mounting leg.

Conventionally, in order to fix this spoiler to the vehicle body, holes are formed in the vehicle body panel corresponding to the bolts protruding from the lower surface of each mounting leg, and the bolts of each mounting leg are passed from above to the vehicle body. A nut was screwed into each bolt from the back of the panel, and the nut was fastened to the back of the vehicle body panel.

<Problems to be solved by the invention> However, this means that the workability in the automobile production line is extremely poor because a nut must be screwed in from the back of the vehicle body panel to one of the bolts of each mounting leg of the spoiler. , When installing the body of the spoiler with the bolt protruding from the spoiler, there are problems such as scratching the paint on the surface of the body panel or tightening the nut, the back of the body panel is scratched by the nut and rusts from it. is there.

<Means for Solving the Problems> Therefore, in the present invention, when the work is the spoiler,
Without using nuts while using bolts protruding from the bottom surface of each mounting leg, you can easily fix by simply pushing it into the hole of the body panel from above and without damaging the body panel, and remove it as necessary. And a flexible tubular portion in the up-and-down direction which has an engaging portion which is formed in an annular step at the upper end and which engages with the hole edge of the panel. A lower end is connected to the flexible tubular portion, and a central shaft portion that extends upward inside the flexible tubular portion is provided, and a mounting hole that is screwed into a bolt protruding from the work and is attached to the central axial portion is opened at the upper end. At the same time, the tool engaging portion having a cross-sectional shape other than a circle is provided downward at the lower end of the flexible tube portion.

<Embodiment> In each of the illustrated embodiments, 1 is a flexible tubular portion, 2 is an engaging portion formed in an annular step at its upper end, 3 is a central shaft portion, 4 is a mounting hole opened at its upper end, 5 is a spoiler which is a work, 6 is an integral bolt projecting from the lower surface of its mounting leg 5 ', 7 is a tool engaging portion having a hexagonal outer shape, 8 is a panel, and 9 is a hole in the panel.

The flexible tubular portion 1 is thin and has a tapered tubular shape whose diameter increases upward, and the engaging portion 2 is formed in an annular shape by an annular step at the outer peripheral edge portion of its upper end. The diameter of the engaging part 2 is 0. than the diameter of the hole 9 of the panel (width W when the hole is oval).
It is preferable that the engaging portion 2 is made larger by about 1 mm so that when the engaging portion 2 enters the hole 9, the engaging portion is slightly compressed and deformed.

The cylindrical wall of the central shaft portion 3 having the mounting hole 4 is thick and firmly holds the bolt of the work screwed into the mounting hole 4. The diameter of the mounting hole 4 may be such that when the mounting hole 4 is screwed into a bolt 6 of a workpiece, a female screw may be engraved on the entire inner circumference by the bolt. A plurality of inward vertical ridges 10 are provided at equal intervals in the circumferential direction, and female bolts are engraved on the vertical ridges of the workpiece so that the bolts of the workpiece can be screwed in easily. .

The coupler of the embodiment shown in FIGS. 1 to 3 is a one-piece molded product made of plastic, and the central shaft portion 3 stands upright from the inner circumference of the small diameter portion of the flexible tubular portion 1. The upper surface of the central shaft portion 3 is equal to the thickness of the panel 8 than the horizontal step surface 2'of the engaging portion 2, or when the rubber packing 11 is laid on the panel 8, the total compression thickness of the packing is added. It is raised by the thickness.

The mounting hole 4 in the central shaft portion 3 is screwed into the bolt 6 projecting from the lower surface of the mounting leg 5'of the spoiler, and the upper surface of the central shaft portion 3 is placed in contact with the lower surface of the mounting leg.

Then, the tool engaging portion 7 is inserted into the hole 9 in the panel 8 of the vehicle body.
Push the connector attached to the spoiler from above, starting from above. As a result, the tool engagement portion 7 passes under the hole 9 without resistance, but since the diameter of the flexible tubular portion 1 is enlarged upward, the flexible tubular portion 1 is deformed and tries to pass through the hole downward so that the mounting leg 5 ' When the lower surface abuts the upper surface of the panel 8, or when the packing 11 is laid on the upper surface of the panel 8, the lower surface of the mounting leg compresses the packing, and abuts the upper surface of the panel 8 via the compressed packing. Then, the engaging portion 2 is located at the edge of the hole 9 of the panel. As a result, the flexible tube portion 1 is restored to some extent, and the hole 9
Is oval, the width W of the hole is slightly smaller than the outer diameter of the engaging portion 2, so that the upper portion of the flexible tubular portion is oval as shown in FIG. It is fixed on the panel by sandwiching the edge of the hole 9 of the panel between the lower surface of 5'and the engaging portion 2 on the flexible tube portion 1 of the fitting attached to the bolt.

To remove the spoiler from the panel for repairing the vehicle body, turn the tool engaging portion 7 of the connector projecting on the back surface of the panel with a spanner or the like, and remove the connector from the bolt 6 on the lower surface of the mounting leg 5 '. The spoiler comes off by pulling it out. After removing the spoiler, next, in order to fix the spoiler, the mounting hole 4 of the central shaft portion is screwed into the bolt 6 on the lower surface of the mounting leg again, and the coupler is mounted and placed. The tool engaging portion 7 can also be used to screw the mounting hole 4 into the bolt 6 for mounting.

If the hole 9 of the panel is placed in an oval shape, the mounting position of the spoiler can be adjusted in the longitudinal direction of the hole.

The coupling shown in FIGS. 4 to 9 is an inner member 12 having a central shaft portion 3 and an outer member having a flexible tube portion 1 and a tool engaging portion 7.
13 and both members 12, 13 are separately molded of plastic.

The inner member 12 has an umbrella-shaped collar 14 that extends outward from around the upper end of the central shaft portion 3, and has an angular shaft portion 15 having a smaller outer shape than the shaft portion under the central shaft portion and an angular shaft portion 15. Small diameter neck shaft that runs underneath
16 and a disc part 17 under the neck shank that has a larger outer diameter than the neck shank
Are equipped concentrically.

Further, the outer member 13 has a midsole 18 in the middle of the height, the flexible tubular portion 1 is formed above the midsole 18, and the outer surface from the bottom to the bottom is the tool engaging portion 7. . Inside the portion from the insole to the bottom, a square hole portion 19 into which the square shaft portion 15 of the inner member fits, a disc portion 17 can pass therethrough, and the length in the vertical direction is larger than that of the neck shaft portion 16. The small-diameter hole portion 20 is provided so as to concentrically penetrate therethrough, and a plurality of (four in the drawing) claws 21 projecting obliquely downward toward the center from around the lower end of the small-diameter hole portion 20. It is provided at intervals in the direction. The claws 21 are for locking the disc portion 17 below the neck shaft portion 16 of the inner member 12 to prevent the inner member from slipping upward from the outer member.

Then, by aligning the angular shaft portion 15 of the inner member and the square hole portion 19 of the outer member, and pushing the disk member 17 into the square hole portion 19 of the outer member and the small diameter hole portion 20 from above, the inner member is pushed. , The disk portion 17 passes through the square hole portion 19 and the small diameter hole portion 20 without any resistance, and when it comes out from the small diameter hole portion 20, it pushes the claws 21 outwardly and spreads the lower end of the square shaft portion 15 into the square hole portion 19. When it comes into contact with the bottom of the disk, the disk part passes downward between the claws 21 ... As a result, each claw snaps back to lock the disk portion 17, and the inner member assembled to the outer member by the locking and the contact between the lower end of the square shaft portion and the bottom of the square hole portion. Stuck up and down. In this assembled state, between the horizontal step surface 2'of the engaging portion 2 of the outer member and the lower surface of the collar 14 of the inner member, the thickness of the panel 8 or when the rubber packing 11 is laid on the panel 8 An interval is formed which is slightly thinner than the total thickness.

Therefore, in this embodiment as well, the mounting hole 4 of the central shaft portion 3 on the inner member is screwed into the bolt 6 of the workpiece, and the upper end of the central shaft portion is brought into contact with the lower surface of the workpiece (the lower surface of the mounting leg of the spoiler). In this case, since the angular shaft portion 15 of the inner member is fitted into the angular hole portion 19 of the outer member and both members 12 and 13 rotate integrally, the tool engaging portion 7 of the outer member is bitten and rotated by a spanner or the like. be able to.

In this way, when the fastener is attached to the bolt 6 of the work, the fastener is pushed into the hole 9 of the panel from above, and the collar 14 of the outer member is pressed against the surface of the panel and compressed. As a result, the flexible tube portion 1 of the outer member tries to pass through the hole 9 while deforming similarly to the above-described embodiment, and when the engaging portion 2 is located inside the hole 9, the flexible tube portion 1 is somewhat deformed. When restored, if the hole 9 is oval, the upper part of the flexible tubular part becomes oval as well, and the spoiler has a hole 9 of the panel between the lower surface of the collar 14 of the connector and the engaging part 2. It is fixed on the panel by sandwiching the edge. Of course, when the rubber packing 11 is fitted under the brim 14 of the coupler, the packing 11 is compressed by the brim to the surface of the panel.

To remove the spoiler from the panel, such as to repair the vehicle body, turn the tool engaging part 7 of the connector projecting on the back surface of the panel with a spanner or the like, and remove the connector from the bolt 6 on the lower surface of the mounting leg 5 '. The spoiler comes off.

In this embodiment, since the coupler has the brim 14 that covers the flexible tubular portion, unlike the above-described embodiment, it is impossible to integrally mold the plastic. Therefore, the outer member and the inner member are molded separately. , It was assembled.

As is clear from the above, the coupling device of the present invention can be formed as an integral one-piece, or the two members can be separately formed and assembled. And since the joint is made of plastic, it does not damage the panel.

<Effect of the Invention> According to the present invention, the work can be easily fixed to the panel by screwing it into the bolt protruding from the lower surface of the work and pushing it into the hole of the panel from above, and without fixing the work to the panel. Accordingly, it is possible to provide a coupling tool capable of removing the work piece from the panel.
