Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a fixing metal clip used for fixing, for example, interior and exterior parts of an automobile to a predetermined panel of a vehicle body.

As shown in FIG. 1, this type of conventional clip has a plate-shaped engagement base 1 formed on both sides with bent portions 3 that are bent upward at a certain angle, and a raised portion at the center of the engagement base 1. The interior and exterior members 4, which are fixed to the panel with the clips, have legs 2, 2 separated and opposed to each other in a rhombic shape that can be bent, respectively.As shown in FIG. The grooves 5, 5 having a U-shaped cross section are formed over the entire area, and the bent portions 3, 3 of the engagement base 1 are press-fitted from the ends into the grooves 5, 5 of the interior/exterior member 4, The engagement base 1 is engaged with the back surface of the interior/exterior member 4, and the clip is slid into a predetermined position on the interior/exterior member 4 using the grooves 5, 5 as guides, and in this state, as shown in FIG. By inserting the legs 2, 2 of the clip into the holes 7 of the panel 6, the legs 2, 2 bend inward, pass through the holes 7, and return to their original rhombic shape due to their own repulsive force. The interior and exterior members 4 were then fixed to the panel 6.

However, in the conventional clip, the inner and outer parts corresponding to the holes 7 of the panel 6 are inserted while the bent parts 3, 3 of the engaging base 1 are forcibly press-fitted into the grooves 5, 5, as described above. Since the structure is such that the member 4 is slid into a predetermined position, the longer the interior/exterior member 4 is, the more complicated the sliding operation becomes. Even if it is slid into a specified position, it is extremely difficult to accurately position the panel 6 with the hole 7 in the conventional press-fit structure, so post-processing such as hot-melt caulking is required to ensure reliable positioning. It is necessary to obtain the desired condition, which not only makes the work more complicated, but also increases costs.

In particular, when the elongated interior/exterior member 4 is fixed to the panel 6 via a large number of clips, each of these drawbacks becomes even more noticeable.

Furthermore, since the ends of the interior and exterior members 4, including the grooves 5, 5, are covered with end caps (not shown) made of plastic, the clips can only be attached before attaching the end caps. However, it also had the disadvantage of lacking flexibility.

Therefore, in view of the above-mentioned drawbacks of the conventional clip, the present invention molds the overall shape of the clip into a substantially omega shape, and makes the lower pieces that project in opposite directions and are spaced apart from each other serve as the retaining pieces that engage with the grooves. In addition, each of the conventional drawbacks is effectively solved by forming an engagement reinforcing claw portion on each of the engagement pieces.

Hereinafter, the present invention will be described in detail based on an illustrative embodiment. As shown in FIG. The legs 12.12 are inserted into the holes 7 of the panel 6, and the lower parts projecting in opposite directions and separated from each other have a U-shaped cross section formed on both sides of the back surface of the interior/exterior member 4 over the entire length in the longitudinal direction. Engagement piece portion 11.11 that engages with each of the grooves 5, 5
By applying an inward external force to each of the leg portions 12.12 to cause the leg portions 12.12 to flex, the gap width A between the respective engaging pieces 11, 11 is reduced, and the external force is reduced. When opened, the deflection of the leg portions 12, 12 is canceled by the repulsive force of the elastic metal plate, and at the same time, the respective engaging pieces 11, 11 are returned to the original gap width A.

In addition, claw portions 13, 13 which are notched and bent as shown in the figure are formed on diagonally located side edges of each of the engaging piece portions 11, 11, and each of the engaging piece portions 11, 11 is formed in the groove 5. .5, the clip itself is securely fixed to the interior/exterior member 4 by causing each claw portion 13.13 to bite into the back surface of the interior/exterior member 4.

It is preferable that the claws 13, 13 are bent in such a manner that they have little resistance in the direction of engagement of the engagement piece 11, but that they have great resistance in the direction of release. Although the state in which the tips of the respective claw portions 13, 13 are both bent downwardly and inwardly is shown, bending upwardly and inwardly is also optional depending on the implementation.

In addition, as shown in the figure, the diagonally located side edges of the leg portions 12.12 are formed with claw portions 14.14 which are notched and bent outwardly and downwardly, and each leg portion 12.12 is formed in the hole 7 of the panel 6. When fully inserted, the tip of each claw part 14.14 is configured to insert into the back surface of the panel 6, and notches 15.15 are formed on both sides of the upper end to which each leg part 12.12 is connected. , the leg portions 12.12 can be easily bent for insertion into the hole 7 of the panel 6 and for reducing the gap width between the engaging pieces 11.11.

Therefore, in the clip of the present invention having the above structure, the engaging base 1 is engaged with the groove 5° 5 of the interior/exterior member 4 by press-fitting the bent portions 3, 3 on both sides, as in the conventional clip. The fifth
As shown in FIG. By simply reducing the gap width A between the engaging pieces 11 and 11 so that it is smaller than the width between the engagement pieces 11, 11, and directly positioning the gap width A on the back surface of the interior/exterior member 4 and releasing the hand, the image shown in FIG. As shown, each of the engaging pieces 11, 11 returns to the original gap width A due to the repulsive force and automatically engages with each of the grooves 5, 5.

Moreover, in this engaged state, the bent claws 13, 13 formed on the side edges of each retaining piece 11.11 bite into the back surface of the interior/exterior member 4. It will be reliably positioned and fixed.

Next, when the legs 12.12 of the clip are inserted into the holes 7 of the panel 6 as shown in FIG. As a result, the interior and exterior members 4 are fixed to the panel 6, but in the present invention, the leg portions 12 and 12 are fixed as shown in the same figure.
Since the bent claws 14, 14 formed on the side edges of the panel press the back surface of the panel 6 in the opposite direction, the interior and exterior members 4 will not fall off at all, and the interior and exterior members 4 will be more completely fixed. .

Further, the leg portions 12° 12 are bent when inserted for fixation, but in such a state, the claw portions 13 bite into the engagement pieces 11, 11, respectively, so that the respective engaging pieces 11, 11 are held in the predetermined positions of the respective grooves 5, 5. Since it is securely fixed in position, the gap width A between the engaging pieces 11.11 is never reduced in response to the deflection of the leg portions 12.12.

Therefore, there is no fear that the engagement between the legs 5 and 11 will be inadvertently released when the legs are inserted.

As described above, the present invention does not slide into predetermined positions of interior and exterior members in an engaged state as in the past, but simply reduces the width of the retaining pieces that are separated by bending the legs.
Since the clip can be easily attached, there is no need for the complicated sliding operation required in the past.

In addition, since each engaging piece is reliably positioned and fixed to the interior and exterior members by the claws, there is no need for post-processing such as hot melting or caulking for positioning. This can greatly contribute to work efficiency and cost.

Furthermore, since the present invention is not of a sliding type, it is possible to increase or decrease the number of clips on the interior and exterior members as necessary even after the end cap is attached, resulting in excellent flexibility.

Furthermore, it goes without saying that if the panel pressing claws are formed on the legs, the fixation of the interior and exterior members to the panel will be further strengthened.
