Description

[Detailed Description of the Invention] This invention relates to a plastic clip for fixing a C-shaped section to a metal plate surface.

For example, in the automobile industry, various types of clips are used to secure decorative moldings to the exterior of the car body.
Conventional clips are difficult to remove once the molding is fixed to the vehicle body, and it is time-consuming to repair a damaged vehicle body and attach a new molding to the vehicle body.

In view of the above, the present invention is not limited to moldings, but it is possible to easily fix the C-shaped cross-section material by rotating it 174 times, and to easily remove it from the fixed state by rotating it again 114 times. This will be explained below with reference to illustrated embodiments.

The clip of the present invention has a C-shaped cross-section material, for example, an insertion piece 2 that is inserted into the interior from one end of the molding 1, a neck part 3 that projects from the center of one side of the insertion piece 2 and passes through the opening groove 1' of the molding, and It is integrally provided with an elongated head piece 4 having a rectangular or elliptical long side and short side provided at the tip thereof, and is made of plastic with appropriate elasticity.

The insertion piece 2 protrudes outward from the central part 5 and the equally spaced positions around the central part 5, and rotates the insertion piece 2 inside the molding 1 by 17 degrees.
It has two pairs of flexible blades ω, 6a and 6b, 6b, which are opposed to each other and limit four rotations.

In the embodiment of FIGS. 1 to 7, the central portion 5 of the insertion piece 2 is square, and each flexible wing projects obliquely outwardly from each corner of the square by the same amount, and at the base of each wing. is thin flexible part 6
' is formed.

The shape of the central portion 5 is not limited to a square, but may be other shapes such as a circle.

The distance between the free ends of each pair of flexible wings is slightly larger than the internal width W of the molding 1.

Therefore, one pair of the four flexible wings is opposed to each other, for example 6a.

By bending the thin flexible portion 6a and positioning the neck 3 in the opening groove 1' (FIG. 4), the insertion piece 2 can be inserted into the interior from one end of the molding 1, and the bent pair The free end of the flexible wing engages the inner widthwise edge of the molding with a restoring force and is held in place inside the molding.

Note that in this state, the other pair of flexible wings 6b. The length of each flexible wing is determined so that the free end of 6b is slightly separated from the inner edge of the molding (FIG. 6).

In this embodiment, when the insertion piece 2 inside the molding is rotated, for example, counterclockwise, the free ends of the pair of unflexed flexible wings 6b, 6b are received by the inner edge of the molding. It is stopped and cannot rotate, but in the opposite clockwise direction (
Arrow a) in Figure 6 shows that it can be rotated up to 1/4 rotation, and 17
By making four rotations, the other pair of flexible wings 6b
, 6b are bent at the inner edges in the width direction of the molding, and at the same time, the orientation of the elongated head piece 4 provided at the tip of the neck 3 changes by 90° (FIG. 7).

To fix the molding to the vehicle body, slotted holes 7 matching the shape of the elongated head piece 4 are opened at predetermined intervals in the front panel 8 of the vehicle body along the fixing position of the molding.

In this case, the orientation of the elongated hole is matched to the orientation of the elongated head piece 4 when either pair of flexible wings is bent and held inside the molding.

In addition, the same number of clips as the number of slotted holes are inserted into the inside of the molding as described above, and the clips are kept at equal intervals with the slotted holes, and the orientation of the slotted head piece 4 of each clip is set in the direction of the corresponding slotted hole 7. Make them match.

Then, the elongated head piece 4 of each clip is passed through the elongated hole 7 and projected to the back of the elongated hole, and each clip is rotated, for example, 1/4 turn clockwise from the back side of the front panel 8 of the vehicle body.

As a result, the direction of the elongated head piece 4 is changed by 90', and the elongated head piece 4 is perpendicular to the elongated hole on the back side of the elongated hole 7. The back pieces 1a, la and the front panel 8, which face each other at the opening groove 1' of the molding, are sandwiched between them.

In this case, tapered surfaces 4', 4' that descend from the neck 3 toward both ends as shown in the figure are provided on the surfaces of both long side ends of the elongated head piece 4 that contact the front panel 8 from the back side, and the elongated head piece 4 When the tapered surface 4 is made to protrude from the back of the elongated hole 7 and rotated 174 times,
'.

4' contacts the front panel 8 from the back and draws the clip toward the front panel, the clamping force can be further increased.
preferable.

The molding 1 fixed on the surface of the front panel in this way
can be easily removed by operating from the back side of the front panel and rotating it further by 4 degrees so that the orientation of the elongated head piece 4 is aligned in the same direction as the elongated hole 7.

To rotate the clip 18 times on the back side of the front panel, you can, for example, hold the elongated head piece with a pinching tool such as pliers and rotate it, but in this example, insert the tip of the screwdriver into the center of the elongated head piece. An engaging recess 9 that can be rotated is provided so that it can be rotated by a screwdriver.

The clip of the above embodiment cannot be rotated in one defined direction.

The embodiment shown in FIGS. 8 and 9 is designed to be able to rotate in either direction, and is an arch-shaped flexible wing whose ends are connected to the center from each side of a square central portion 5. are made to protrude in four directions to constitute the insertion piece 2, and the arch-shaped flexible wings are arranged in pairs, 6a and 6a, and 6b and 6b, which are opposite to each other, and between the tops of the multiple pairs of flexible wings. The distance is slightly larger than the interior W of the mall.

Therefore, the clip can be inserted into the interior of the molding 1 by slightly bending the tops of the pair of opposing flexible wings, and can be held at a predetermined insertion position.

Then, it can be rotated in either clockwise direction, the orientation of the elongated head piece 4 can be changed to 90 degrees, and the molding 1 can be removably fixed to the surface of the front panel in the same way, as described above. It can be used in the same way as the example.

This flexible wing can be rotated in both directions even if it has a free end by forming a cut-off part 10 at the top or other parts.
