[Problem that the idea aims to solve]

However, with this conventional clip-based fixation structure, the following problems occur: There was a problem as described. i.e. the trim is generally clipped to the bracket It is transported in an assembled state (with parts assembled). However, in the case of the above-mentioned conventional technology, the slit is formed narrower than the diameter of the round hole. However, there was a slight play between the neck and the round hole, which caused the The clip may fall off the trim. Therefore, in such cases If so, check the presence or absence of the clip at the installation site to the vehicle body panel, and check if it has fallen off. If the clip is removed, it will be necessary to reattach the clip, which will increase man-hours. Become.

0004 Also, the neck must be thick enough to pass through the slit. Therefore, play inevitably occurs between the hole and the round hole, which has a larger diameter than the slit width, and this play The fixing performance of the trim to the vehicle body panel is also degraded by the increase in trim length.

[0005] This invention was developed by focusing on the conventional problems mentioned above. It has excellent fixing performance for fixed parts such as trims, and Clip fixing structure prevents deterioration of workability due to the lip falling off. The purpose is to provide a structure.

[0006]

[Means to solve the problem]

Therefore, in this invention, the seat part of the clip has a part in the direction in which the neck part comes out of the slit. forming a second locking part whose movement is regulated by being locked to the mounting part; I tried to achieve the stated purpose.

[0007] In other words, in the fixing structure using the clip of the present invention, one end of the member to be fixed is opened. A mounting part with a clip mounting surface is formed with a slit, and the A mounting hole is formed in the member, and the clip is inserted into the mounting hole and attached to the fixed member. A leg portion provided with a first locking portion that locks the The neck part is formed oppositely with this neck part in between, and the neck part is inserted into the slit. A head portion and a seat portion are provided that sandwich the mounting surface in a state, and the seat portion has a slit. Move the clip in the direction where the neck part comes out of the slit with the clip attached to the A second locking portion is formed that is regulated by being locked to the mounting portion. It was used as a means.

[0008]

[Effect]

To explain the fixing procedure, first attach the neck of the clip to the part to be fixed. Insert the clip into the slit formed on the clip mounting surface of the At the same time as the lip mounting surface is held, the second locking portion of the seat portion is locked to the mounting portion. This restricts the clip from moving in the direction in which the neck portion comes out of the slit. Therefore, even if the member to be fixed is transported in this state, the clip will not fall off. stomach.

[0009] Next, insert the legs of the clip into the mounting holes formed in the member to be fixed, and then insert the legs of the clip into the first locking part. to lock. As a result, the member to be fixed is fixed to the member to be fixed. .

0010 As mentioned above, when the clip is attached to the member to be fixed, the second locking part This restricts the movement of the slit in the direction in which it comes off, which is the opposite direction to the direction in which it is inserted. , it is necessary to make the opening end of the slit narrower than the back side to prevent it from falling off, as in the past. This makes it possible to form a slit with a constant width. Play between the clip and the neck can be eliminated, thereby increasing the rigidity of the clip. The constant performance can be improved.

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

0012 First, the configuration of the embodiment will be explained.

[0013] FIG. 1 is a side view showing a fixing structure using a clip according to an embodiment of the present invention, and FIG. FIG. 3 is a perspective view showing the embodiment clip, and in the figure, 1 is a sectional view taken along line A-A. Trim as the member to be fixed, 2 is the vehicle body as the member to be fixed to which trim 1 is fixed. Showing the panel.

[0014] The trim 1 is attached to cover the interior side of the vehicle body panel 2. It is made of synthetic resin. And on the mounting surface side of this trim 1, A bracket 10 (attachment part) is integrally formed. This bracket 10 A clip mounting surface 10 is formed in a box shape with only one side open and is parallel to the trim 1. A is formed with a slit 10c having a constant width from the opening surface 10b side.

[0015] On the other hand, a rectangular mounting hole 2a is formed in the vehicle body panel 2, and the clip The clip 3 installed between the mounting surface 10a and the mounting hole 2a allows the trim 1 to be attached to the vehicle body. It is fixed to panel 2.

[0016] The clip 3 is integrally molded from a flexible synthetic resin material. The clip 3 has legs 30 that are inserted into the mounting holes 2a of the vehicle body panel 2. ing. That is, the leg portion 30 is formed into a rectangular tube shape that can be inserted into the attachment hole 2a. The tip is tapered. And to this leg part 30 A pair of locking pieces 30a are provided at the center of the side surface of the holder, and are flared toward each other as a first locking portion. , 30b are formed protrudingly, and these locking pieces 30a, 30b are attached to the mounting hole 2a. It is configured so that it is prevented from coming off by being locked to the edge of the mounting hole 2a. . By the way, when inserting the leg portion 30 into the mounting hole 2a, the locking pieces 30a and 30b are The leg portion 30 is elastically deformed toward the inside thereof.

[0017] Furthermore, the clip 3 has a plate with a thickness that is very slightly narrower than the width of the slit 10c. A shaped neck 31 is formed, and a seat plate ( A seat portion) 32 is formed, and a head plate (head) 33 is formed on the opposite side thereof, Both plates 32 and 33 have a clip between them when the neck portion 31 is inserted into the slit 10c. It is formed so that it can hold the lip attachment surface 10a.

[0018] To explain further, the seat plate 32 is a rectangular plate that is long in the longitudinal direction of the neck portion 31. The neck portion 31 is inserted into the seat plate 32 to the deepest part of the slit 10c. When this happens, the neck portion 31 is locked to the side wall edge 10d on the opposite side to the opening surface 10b, and the neck portion 31 is slid. A locking pawl 32 serves as a second locking portion that restricts movement in the direction of coming out of the slit 10c. A is provided. Also, the insertion direction of this locking pawl 32a (indicated by the dashed-dotted arrow) The end face in the direction (in the direction of When the seat plate 32 is inserted into the It is configured to deform.

[0019] The head plate 33 is formed into a rectangular plate shape whose insertion direction side is longer than the neck portion 31. At the same time, there are pushers on both side edges that are inclined so that the leading edge approaches the seat plate 32. Pressure pieces 33a and 33b are integrally formed. These pressing pieces 33a, 33b are The gap width between the tip edge of the bracket 10 and the seat plate 32 is the clip mounting surface of the bracket 10. 10a, and the end on the insertion direction side is tapered. It is cut and inserted into the bracket 10 using this tapered surface 33c as a guide surface. It is structured so that it can be performed smoothly.

[0020] Incidentally, the seat plate 32 is formed to have a width that can close the entire mounting hole 2a. So A seal washer 4 is interposed between the seat plate 32 and the vehicle body panel 2. The mounting hole 2a is watertightly sealed by the seal washer 4.

[0021] Next, the operation of the embodiment will be explained.

[0022] To explain the procedure for fixing trim 1 to vehicle body panel 2, first, attach clip 3 to the trim. Attach to bracket 10 of rim 1. In this case, the neck 31 is attached to the clip mounting surface 1. At this time, insert the clip 3 into the slit 10c formed in 0a. When pressed in the insertion direction, the neck 31 is inserted into the slit 10c. At the same time, the seat plate 32 and both pressing pieces 33a and 33b are pushed apart. The clip mounting surface 10a of the bracket 10 is press-fitted between the head plate 33, and At the time when the neck portion 31 is inserted to the deepest part of the slit 10c, the groove formed on the seat plate 32 The locking pawl 32a locks on the side wall edge 10d of the bracket 10, thereby causing the click The movement of the pulley 3 in the direction of coming out of the slit 10c is restricted.

[0023] Then, for the slit 10c of a constant width, a plate-shaped plate whose width is very slightly narrower than the slit 10c is formed. By inserting the neck part 31, there is no play between the two, and moreover, the neck part 31 is inserted. Due to the repulsive force based on the elasticity of the pressure pieces 33a, 33b, both the pressure pieces 33a, 33b and the seat plate 3 2, the clip mounting surface 10a is strongly held between the clip mounting surface 10a and the clip mounting surface 10a, resulting in a strong mounting state.

[0024] Next, move the trim 1 with the clip 3 attached in this way to the vehicle body panel 2. Fixed to. In this case, first place a seal washer on the mounting surface side of the seat plate 32 of the clip 3. Attach camera 4. After that, the leg portion 30 is inserted into the mounting hole 2a of the vehicle body panel 2. , At this time, a pair of locking pieces 30a are formed on the side surfaces of the leg portion 30 to protrude in a shape that widens toward the end. 30b comes into contact with the edge of the mounting hole 2a, so if you apply a pressing force there in the insertion direction, The leg portion 30 is inserted into the mounting hole 2a while both the locking pieces 30a and 30b are elastically deformed inward. It's being put in. Then, the seal washer 4 is sandwiched between the seat plate 32 and the vehicle body panel 2. At the stage of being held and pressed, both locking pieces 30a and 30b pass through the vehicle body panel 2, and both locking pieces 30a and 30b pass through the vehicle body panel 2, and are locked. The pieces 30a and 30b expand to their original state due to their elastic force and engage with the edge of the mounting hole 2a. will be stopped. The leg portion 30 is now in a state where it is prevented from coming off from the attachment hole 2a. As a result, the trim 1 is firmly fixed to the vehicle body panel 2, and the seal The mounting hole 2a is completely closed by the washer 4.

[0025] As explained above, in the structure of the embodiment of the present invention, the bracket 10 is Since the clip 3 is firmly attached with no play, it can be attached to the vehicle body panel 2. In addition to having excellent fixing performance for trim 1, the locking pawl 32a allows the Since the clip 3 can be prevented from falling off when the clip is This has the effect of preventing the deterioration of

[0026] Moreover, the seat plate 32, which is formed wider than the mounting hole 2a, and the vehicle body panel 2 are interposed. Since the mounting hole 2a is completely closed by the seal washer 4, the vehicle body panel It has the effect of being able to ensure the watertightness of the clip attachment part in 2. There is.

[0027] Above, the embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is as follows. Not limited to examples, design changes, etc. within the scope of the gist of the present invention, etc. Even if there is, it is included in this invention. For example, in the embodiment, the vehicle body part is used as the fixing target member. It shows the trim that covers the passenger compartment side of the panel, and also shows the member to be fixed to which the member to be fixed is fixed. Although vehicle body panels are shown as examples, these are not limited to examples, and include essential If the structure uses clips to fix one member to another, how would it work? It can also be applied to similar structures. In addition, a plate-shaped seat plate or Although the head plate is shown, these shapes are not limited to plate-like shapes; Any shape that can hold the clip mounting surface when inserted into the slot It may be formed into a shape. In addition, regarding the locking part, in the embodiment, Although the locking pawl is shown that only restricts movement in the direction of Holes and protrusions are used if they are locked to restrict movement in the direction of coming out of the slit. Other locking structures may also be applied.

[0028]

[Effect of the idea]

As explained above, in the fixing structure using the clip of the present invention, there is a When the second locking part is formed and the clip is inserted into the slit, the second locking part is In the direction in which the neck of the clip comes out of the slit after it is locked to the attachment part of the part to be fixed. In order to restrict movement of the clip, make sure that the clip does not fall off from the mounting part of the target This effectively prevents the clip from falling off, and prevents the deterioration of work efficiency due to the clip falling off. You can get the effect that you can. In addition, the second locking part allows the clip to be removed. Since it is possible to reliably prevent the product from falling, the opening of the slit is used to prevent it from falling off, as in the past. There is no need to make the end side narrower than the back side, and the slit can be formed to a constant width. This eliminates play between the slit and the neck. This has the effect of improving the fixing performance of the clip. It will be done.
