Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to, for example, one member formed by projecting a boss portion and another member formed by forming an insertion hole of the boss portion. The present invention relates to an improvement of a metal fixing clip that fixes in a polymerized state.

"Prior Art" As a conventional fixing clip of this type, the actual clip 57-No. 15
There is one disclosed in Japanese Patent No. 5308 (particularly FIG. 3).

The conventional fixing clip is integrally formed by punching and bending a metal elastic plate. Specifically, as shown in FIG. 4A, the entire clip body 1 has a substantially Ω-shaped cross section. , A pair of elastic holding pieces 3 having sharpened teeth 3a at the tip edges on both side walls that define the lower opening 2.
3 is formed via the slit 4, and the elastic holding pieces 3 are inclined inward at a constant angle.

In actual use, as shown in FIG. 3B, after the insertion state of the boss portion 5 into the insertion hole 6 is obtained and one member P1 made of synthetic resin is superposed with the other member P2, the insertion hole 6 is inserted.
The tip of the boss portion 5 protruding from the opening 2 of the clip body 1
When inserted into the inside of the boss portion 5 and biting the tip sharpened teeth 3a of the pair of elastic holding pieces 3 and 3 into both side surfaces of the boss portion 5, the pair of elastic holding pieces 3 and 3 hold the pair of elastic holding pieces 3 and 3 with respect to the boss portion 5. Since the clip body 1 is fixed to the boss portion 5, the one member P1 and the other member P2 are superposed and fixed by this.

Therefore, when the conventional clip is used, the sharpened teeth 3a of each elastic holding piece 3 are simply bited into the boss portion 5 inserted into the opening 2 to obtain the fixed state of the clip body 1 and P1 and P2 can be easily fixed to each other.

[Problems to be solved by the invention] However, in the conventional fixing clip, the entire shape of the main body 1 has a substantially Ω-shaped cross section, and the elastic holding pieces 3 are formed on both side walls defining the Ω-shaped shape. Since only the structure for forming the member is used, the load is applied to the clip body 1 in the direction of the arrow X in the drawing not only before the members P1 and P2 are fixed but also after the member is fixed. And Ω of clip body 1
In particular, the lower opening 2 may easily expand due to the deformation of the character shape.

Therefore, in the conventional clip, the Ω-shaped body 1
When the opening 2 expands due to deformation, the pair of elastic holding pieces 3, 3 formed on both side walls that define the opening 2 naturally follow the deformation of both side walls in the direction in which they are separated from each other. As it moves, the opposing distance between both 3 and 3 will be widened, so
As a result, the state of biting into the boss portion 5 becomes very weak, and the members P1 and P2 in the polymerization fixed state play loosely, the fixed state of both P1 and P2 becomes unsteady, or the clip itself becomes boss. There has been a problem that the members P1 and P2 become detached from the portion 5 and cannot be fixed.

[Means for Solving the Problems] The present invention has been developed to effectively solve the conventional problems, and includes a clip body having a substantially Ω shape, and a lower side of the clip body. A metal formed with an opening into which a boss portion projecting from the member is inserted, and a pair of elastic holding pieces for holding the boss portion inserted into the opening from both sides on both side walls defining the opening. Assuming a fixed clip made of metal, an opening for inserting the boss portion is formed in the central portion of the clip body, and a pair of elastic holding pieces are continuously formed at the edge of the opening. A lock arm having a locking portion and a substantially Ω-shaped rising wall portion having a free end edge are formed so that the free end edge of the rising wall portion and the tip locking portion of the lock arm face each other. We adopted a configuration to stop it.

According to the "action", even in the present invention, after the insertion state of the boss portion into the insertion hole is obtained and one member is overlapped with the other member, the tip of the boss portion protruding from the insertion hole is fixed to the clip body. It goes without saying that one member and the other member can be easily polymerized and fixed by inserting the boss portion into the opening formed in the central portion of the above and holding the boss portion from both sides with a pair of elastic holding pieces.

However, according to the present invention, it is of course possible to prevent the rising wall portion from expanding due to the locking state of the free end edge of the locking arm formed on both sides of the clip body and the free edge of the rising wall portion. ,
Finally, since the expansion of the opening continuous with the elastic holding piece is completely prevented, even if a load similar to the conventional load is applied to the clip body, there is no fear that the opening will be expanded inadvertently.

Therefore, there is no concern that the pair of elastic holding pieces will be separated from each other and the biting state on both side surfaces of the boss part will not weaken.Therefore, the members in the overlapping fixed state may rattle, or the clip itself may drop from the boss part. Is completely prevented.

[Examples] Hereinafter, the present invention will be described in detail with reference to an illustrated example. The fixing clip according to the example is also integrally formed by punching and bending a metal elastic plate,
Although it has an opening for inserting a boss portion projectingly provided in one member and a pair of elastic holding pieces for holding the boss portion inserted in the opening from both sides, the feature is that
As shown in FIG. 1, an opening 12 into which a boss portion is inserted is formed in the central portion of the clip body 11, and a pair of elastic holding pieces 13, 13 are continuously formed at the edge of the opening 12 so as to be inclined at a constant angle. Then, the pair of elastic holding pieces 13
Each of the sharp tip teeth 3a of 13 is bited into both side surfaces of the boss portion, and the opening 12 is formed in each side portion of the clip body 11.
The lock structure 14 for preventing the expansion of the above is newly added.

The lock structure 14 will be described in detail. As shown in FIG. 2, the lock arm 15 having the folded back end locking portions 15a on both sides of the clip body 11 and the lock arm 1 are also provided.
5, the substantially Ω-shaped rising wall portions 16 each having a free end edge 16a that is locked to the tip locking portion 15a are independently formed, and the free end edges 16a of the Ω-shaped rising wall portions 16 are locked. Arm 1
By locking the folded back end locking portion 15a of FIG. 5 in a state of facing each other, the Ω-shaped expansion of each rising wall portion 16 is prevented, and at the same time, an opening continuing from the rising wall portion 16 to the inside. 12 is configured to prevent the expansion.

In the present embodiment, the lock arms 15 and the rising wall portions 16 of the lock structure 14 attached to both sides are formed so as to face in opposite directions on each side. It is also possible to form 15 and the rising wall portion 16 in the same direction on both sides depending on the implementation.

Therefore, by using the metal fixing clip having such a configuration, one member P1 made of synthetic resin having the boss portion 5 protruding therefrom and the other member P2 having the insertion hole 6 formed therein are overlapped with each other. When fixing, as shown in FIG. 3, after the insertion state of the boss portion 5 into the insertion hole 6 is obtained and the other member P2 is superposed on the one member P1, the boss portion 5 protruding from the insertion hole 6 is obtained. The tip of the elastic body is inserted into the opening 12 formed in the central portion of the clip body 11, and a pair of elastic holding pieces 13, 13 are provided on both side surfaces of the boss portion 5.
If each of the pointed sharp teeth 3a is forcibly bited, the one member P1 and the other member P2 are superposed and fixed.

Therefore, for example, if the fixing clip according to the present embodiment is provided with the lock structures 14 on both sides of the clip body 11,
Fixing work can be performed extremely easily without any change from the conventional clip.

However, in the present embodiment, the rising wall portion 16 is locked on both sides of the clip body 11 by the locking state of the tip locking portion 15a of the lock arm 15 and the free end edge 16a of the Ω-shaped rising wall portion 16. In addition to the prevention of the Ω-shaped expansion, the expansion of the opening 12 that is continuous with the elastic holding piece 13 is completely prevented, so that the members P1 and P2 are fixed in the fixed state. Even if a load is applied to the clip body 11 in the direction of the arrow X in the figure, the opening 12 will never inadvertently expand.

Therefore, as in the conventional case, there is no fear that the pair of elastic holding pieces 13 and 13 are separated from each other and the biting state on both side surfaces of the boss portion 5 is weakened. It is possible to completely prevent the certain members P1 and P2 from rattling and the clip body 11 from falling off the boss portion 5.

Even if an unexpected external force or the like is applied to the clip body 11 itself before use, due to the locking state of the tip locking portion 15a of the lock arm 15 and the free end edge 16a of the Ω-shaped rising wall portion 16 described above, Similarly, it is needless to say that the opening 12 can be prevented from expanding.

[Advantage of Invention] As described above, according to the present invention, an opening for inserting a boss portion of a member is formed in a central portion of a clip body, and a pair of elastic holding pieces are continuously formed at an edge of the opening, while a clip is formed. A lock arm having a tip locking portion and a rising wall portion having a free end edge are formed on both sides of the main body, and the free edge of the rising wall portion and the tip locking portion of the lock arm face each other. Since it is characterized in that it is locked in the state, depending on the locking state of the free end edge of the rising wall portion and the tip locking portion of the lock arm,
In addition to preventing expansion of each rising wall, in the end, it is possible to effectively prevent expansion of the opening that is continuous with the elastic holding piece.

Therefore, even if a load is applied to the clip body, there is no concern that the opening will inadvertently expand.Therefore, as in the conventional case, the pair of elastic gripping pieces are separated from each other, and the biting state on both side surfaces of the boss portion is prevented. As a result of eliminating the fear of weakening at all, it is possible to completely prevent the fixed members from rattling each other and the clip itself from falling off the boss portion.
