The distal end 5 is formed into a curved shape with a larger diameter than the proximal end as a guide for introduction.

When the shaft portion 3 is press-fitted into the mounting holes 8 and 9 formed in the mounting member 6 and the support member 7, respectively, the rib 4 is elastically deformed and fitted into the mounting hole 9, and the flange 2 is formed on the outer surface of the mounting member 6. When the ribs 4 are pressed against each other, one of the ribs 4 engages with the inner edge of the mounting hole 9 of the support member 7, and the other rib 4 presses against the circumferential surface of the mounting hole 9, so that the mounting member 6 is attached to the support member. It is set to be fixed at 7.

However, in the clip 1 in this conventional example, unless the plate thickness of the support member 7 is thicker than a certain level, the engagement state between the rib 4 and the mounting hole 9 will be insufficient, and a predetermined holding force cannot be obtained. It cannot function satisfactorily in the case of a thin supporting member 7 such as a vehicle body panel.

Furthermore, since the watertightness is weak, there is a problem that it cannot be used in areas that require waterproofing measures.

Moreover, FIG. 6 shows another conventional example,
It is disclosed in JP-A-54-111046.

In this conventional example, the clip 10 consists of a male member 11 and a female member 12, the male member 11 has a head 13 and a shaft 14, and the head 13 has a main flange 15.
, a neck portion 16 , and a retaining flange 17 ,
On the other hand, the shaft portion 14 has a spherical engagement portion 1 with an enlarged diameter at the tip.
8, and elastic wing pieces 19 are formed at the base end to project outward in a radial manner.

Further, the female member 12 has a body part 20 that is open at one end and is hollow inside, and a mounting flange 21 provided on the outer peripheral surface of the opening of the body part 20. An annular locking portion 22 with which the engaging portion 18 is removably engaged is provided, and a locking protrusion 23 is formed on the outer surface.

Therefore, the female member 12 is inserted into the mounting hole 9 of the support member 7.
is press-fitted, and the locking protrusion 23 is engaged with the inner edge of the mounting hole 9. On the other hand, in the mounting hole 8 portion of the mounting member 6, while the mounting member 6 is held between the main flange 15 and the holding flange 17, the male The mounting member 6 is fixed to the support member 7 by fitting the shaft portion 14 of the member 11 into the hollow interior of the female member 12 and engaging the engaging portion 18 with the locking portion 22.

However, in this conventional example, the spherical engaging portion 1
Since the male member 11 and the female member 12 are connected only by engaging the corresponding annular locking portion 22, there is a problem with the holding force. is the engaging part 18 and the locking part 2
It is necessary to form the relative shape with 2 accurately, and high precision is required.

Furthermore, since the mounting member 6 is configured to be sandwiched between the main flange 15 and the holding flange 17, there is a limit to the ability of the mounting member 6 to absorb thickness errors, and there are several types with different thicknesses. The problem is that it is impossible to share the same mounting member.

(Purpose of the invention) The present invention was developed in view of these conventional problems, and has excellent holding power for the mounting member, can absorb changes in the plate thickness of the mounting member, has high waterproof performance, and has a The purpose of the present invention is to provide a fixing clip that has excellent workability during installation and removal.

(Means for solving the problem) In order to achieve the above purpose, in this invention,
A fixing clip for attaching a mounting member to a support member includes a male member and a female member, the male member having a head flange that abuts the outer surface of the mounting member, and a shaft integrally extending from the flange. and a plurality of ribs protruding outward from the shaft portion at predetermined intervals along the axial direction of the shaft portion, the female member having a bottomed cylindrical body portion with an open end and a hollow interior. a screw groove carved into the inner wall surface of the main body so that each of the ribs can be engaged with the main body; and a sealing flange provided at the open end of the main body and elastically brought into close contact with the outer surface of the support member. and a plurality of abutting portions formed to protrude outward by a predetermined distance from the outer wall surface of the main body portion, and an elastic locking portion, and when installed, the contact portions are formed on the inner circumferential surface of the mounting hole of the support member. The present invention is characterized by a fixing clip that makes elastic contact only at each of the abutting portions and forms a predetermined clearance between the inner circumferential surface and the outer wall surface of the main body portion at other portions.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1 to 4 show an embodiment of the present invention, and a fixing clip 30 according to the present embodiment has a male member 3.
1 and a female member 32.

As shown in FIG. 1, the male member 31 has an elastic head flange 33 and a shaft portion 34 extending integrally from the lower surface of the flange 33.

A screwdriver engagement groove 35 for removal is carved in the top of the head flange 33.

The shaft portion 34 is provided with elastic wing pieces 36 formed at its base end to protrude radially in all directions from the main body,
A plurality of ribs 37 are formed protruding below the elastic wing pieces 36 at predetermined intervals along the axial direction of the main body.

The ribs 37 each have an elastic plate shape with a predetermined wall thickness, and each outer surface is formed into a so-called tree shape that slopes upward as shown in the figure, so that the ribs 37 are arranged in the direction of movement at the time of installation (downward in the figure). ) to each rib 3
Due to the elastic deformation of 7, it is easy to advance, and a predetermined resistance force is developed in the pulling direction (upward in the figure).

Furthermore, a substantially hemispherical introduction protrusion 38 is formed at the tip of the shaft portion 34 .

On the other hand, the female member 32 has a bottomed cylindrical main body 39 that is open at one end and has a predetermined wall thickness and is hollow inside, and a sealing flange 40 that is thin and has elasticity is provided on the outer periphery of the open end. The inner wall surface of the main body portion 39 is provided with a threaded groove 4 at a pitch in which each of the ribs 37 can be engaged.
1 is engraved.

Further, a plurality of (four in this embodiment) elastic locking portions 42 are formed protruding from the outer wall surface of the main body portion 39, and an upper step portion 43 of each elastic locking portion 42 supports as described below. It can be elastically engaged with the inner edge of the attachment hole 9 of the member 7.

Furthermore, the upper step portion 43 of each elastic locking portion 42
Continuing on from each other, each directly above the surrounding main body portion 39
A contact portion 4 is formed to protrude outward by a predetermined dimension from the outer wall surface and is in contact with a mounting hole 9 of a support member 7, which will be described later.
4 is formed.

Next, a manner of attaching the fixing clip 30 according to this embodiment will be explained.

FIG. 3 shows an example in which a carpet 6 as a mounting member is fixed to a support member 7 made of a body panel and a press board in the trunk of a vehicle.
For attachment, first the female member 32 is fitted into the attachment hole 9 provided at a predetermined position of the support member 7 and fixed.

At this time, the sealing flange 40 of the female member 32 is elastically deformed and comes into close contact with the circumferential surface of the mounting hole 9 of the support member 7, and each elastic locking portion 42 is elastically deformed inward and fitted into the mounting hole 9. However, the female member 32 is fixed by each step 43 engaging with the inner edge of the attachment hole 9.

Further, each of the contact portions 4 is provided directly above each step portion 43.
4, as shown in FIG. A slight clearance 45 is created between the peripheral surface 91 and the peripheral surface 91 .

Therefore, the entire outer wall surface of the main body portion 39 is the inner peripheral surface 91.
The main body portion 39 can have cushioning properties compared to the case where the main body portion 39 comes into contact with the main body portion 39.

Next, the mounting member 6 is laid on the sealing flange 40 of the female member 32 with the mounting hole 8 aligned with the mounting hole 9, and the shaft portion 34 of the male member 31 is inserted into the mounting hole 8 from above. The female member 32 is press-fitted into the hollow portion of the female member 32 through the connector.

Thus, in a state where the head flange 33 is pressed against the outer surface of the mounting member 6, each rib 37 of the shaft portion 34
It engages with the screw groove 41 at the corresponding position, and the head flange 33
The mounting member 6 is firmly fixed to the support member 7 via the female member 31 due to the clamping force between and each rib 37 .

That is, in this embodiment, the threaded groove 4 of the female member 31
Since the mounting member 6 is connected to the support member 7 by engaging each rib 37 of the male member 31 with 1, the holding force is strong, and due to the shape of the rib 37, the resistance force in the pulling direction is high. Therefore, there is no risk of the male member 31 falling off due to vibrations of the vehicle body or the like.

In addition, since the rib 37 can engage with any position of the screw groove 41, even if the thickness of the mounting member 6 changes, it has a thickness absorption ability that can be shared by the mounting members 6 of various thicknesses. have

Further, the sealing flange 40 of the female member 32 is in watertight contact with the support member 7, and the head flange 33 of the male member 31 is in close contact with the outer surface of the mounting member 6, and furthermore, the sealing flange 40 of the female member 32 is in close contact with the outer surface of the mounting member 6. Even if water enters through the mounting hole 8 between the mounting member and the mounting member, it will only reach the hollow part of the main body part 39, which has a cylindrical shape with a bottom, and will not enter the interior. Intrusion can be effectively prevented.

Further, as described above, only the contact portions 44 are in elastic contact with the inner circumferential surface 91 of the mounting hole 9, and the other portions have clearances 45, so that the cushion of the main body portion 39 of the female member 32 Improved sex,
The insertion force at the time of insertion is small, and the female member 32
It is characterized by low resistance and easy removal when it is removed.

Furthermore, when removing the male member 31, each rib 37 rotates along the threaded groove 41 by fitting a driver (not shown) into the engagement groove 35 of the head flange 33 and rotating it in a predetermined direction. It can be easily removed.

Further, when attaching the male member 31, each elastic wing piece 36 provided on the shaft portion 34 engages with the attachment hole 8 of the attachment member 6, and serves as a guide during insertion, making it possible to attach the male member 31 in the correct position. I'm starting to be able to do it.

In this embodiment, the mounting hole 9 of the support member 7 is a round hole, but even if the mounting hole 9 is a square hole, the outer wall surface of the main body 39 of the female member 32 may be made to correspond to this. It goes without saying that various modifications are possible without departing from the gist of the present invention, such as by making it into a rectangular shape.

(Effects of the Invention) The present invention is constructed as described above, and the presence of the sealing flange that elastically comes into close contact with the outer surface of the support member and the bottomed cylindrical main body significantly improves waterproof performance.

Also, during installation, only the contact portions come into elastic contact with the inner peripheral surface of the mounting hole of the support member, and a predetermined clearance is formed between the inner peripheral surface and the outer wall surface of the main body at other parts. Because of this structure, the cushioning properties of the main body portion of the female member are improved, the insertion force required during insertion is small, and the female member can be easily removed with low resistance when removed.

Furthermore, since the engagement is maintained by biting each rib of the male member into the threaded groove of the female member,
The holding force is significantly improved compared to the conventional example, and it can be used for mounting members of any thickness.
