And the conventional structure contained in the conventional fixture is demonstrated using the same code | symbol.

Figure 3a is a perspective view of the present fixture and Figure 4 is a cross-sectional view showing the assembly of the present fixture. Referring to this, the fixture consists of a base 110 in the form of a plate and a hook 120 in the form of a wedge.

In addition, the base 110 is formed in a flat plate shape so as to extend a predetermined length in front and rear of the hook, and the extension part is supported by the inner surface of the body panel of the vehicle at the time of assembly. A fastening hole 111 to be fastened is formed.

In addition, the base is cut in a 'c' shape is bent upwards, the lower portion is bent in a direction away from each other and then the upper portion of the pair of guide flanges 112 are bent in a direction facing each other of the hook It is provided so as to be positioned in the front and rear, respectively, when assembling the guide flange 112 at the time of assembly to guide the assembly to the predetermined position in the coupling hole 11 of the body panel 10, and also the guide flange 112 lower portion In close contact with the circumferential surface 11a of the coupling hole 11 of the panel 10, the fastener is prevented from flowing in the front and rear directions.

The hook 120 extends downward from both sides of the support arm 121a at the upper end of the support arm 121a and the support arm 121a bent upwardly in a direction facing each other on both sides of the base 110. And a pair of retaining arms 122 bent inclined downward in a direction away from each other on both sides of the flange 121b, and a direction facing each other at the lower end of the retaining arm 122 Retaining part 123 bent downwardly inclined with a retaining jaw that is bent downward at the lower end of the retaining part 123 and hung on the circumferential surface 11a of the coupling hole 11 of the body panel 10 ( 124 and at least one anti-noise protrusion 125 which suppresses the generation of noise due to mutual contact of the flanges 121b protruding in the direction facing the facing surface of the flange 121b.

In this case, the support arm 121a is for rigidly connecting the hook 120 to the base 110. The support arm 121a is formed at the center of the hook 120, and the strength of the support arm 121a is improved. To this end, the support arm 121a may further include beads 126 extending in the vertical direction and protruding in a direction facing each other.

 In addition, the flange 121b is to reinforce the strength and rigidity of the upper end of the hook 120 and has a bent shape by extending the end portions of the flanges 121b facing each other downward in a predetermined length, where downward The bent length is preferably 3 to 6 mm.

When the passenger grabs the auxiliary handle fixed to the body panel 10 of the vehicle while the vehicle is running, the force is applied downward and the flange faces each other by the acceleration force and the deceleration force generated by the driving of the vehicle. At least one anti-noise protrusion 125 protruding in the direction facing the opposite surface of the flange 121b as a means for preventing this, because there is a possibility that the opposite surfaces of the (121b) are in contact with each other and there is a possibility of noise. It is provided to make a point contact between the flange (121b) to suppress the generation of noise.

The retaining arm 122, the retaining part 123, and the retaining jaw 124 are for fixing the fastener to the coupling hole 11 of the body panel 10. When the hook 120 is pushed against the coupling hole 11 of the body panel 10, the retaining arm 122 is deformed in a direction facing each other and then inserted into the coupling hole 11 of the body panel 10 and then again. Elastic recovery, and thus the retaining jaw 124 is in close contact with the side surface of the circumferential surface 11a of the coupling hole 11 of the body panel 10, and the retaining portion 123 is the body panel 10. The fastener is firmly fixed to the coupling hole 11 of the body panel 10 by being in close contact with the upper portion of the circumferential surface 11a of the coupling hole 11. On the other hand, the retaining arm 122 may be further formed with beads 127 extending in the vertical direction and protruding in a direction facing each other to improve the strength.

It is to be able to strengthen the rigidity of the connection portion 122 and the flange 121b.

To this end, the incision surface 128 is further extended to the connection portion of the support arm 121a and the retaining arm 122. At this time, the incision surface 128 is formed to extend from the connecting portion to the support arm 121a side, the width of the connecting portion of the retaining arm 122 and the flange 121b other than the connecting portion of the retaining arm 122 To form wider than the width of.

For example, this incision surface 128 is achieved by forming a circular hole therethrough. At this time, the circular incision surface 128 is achieved by making one side contact the edge side of the retaining arm 122, and the radius thereof is wider than the width between the support arm 121a and the retaining arm 122. . Thus, the width of the retaining arm 122 is to be widened by removing the quadrant from the square having a radius of the circular incision surface (128).

Hereinafter, the manufacturing cost of the conventional fixture and the present fixture is compared.

First, as compared with the manufacturing process, as described above, the hook 33 of the conventional fixture is bent upwardly inclined in the direction facing each other on both sides of the base 31 to form the inner wall 34, the upper side of the inner wall 34 The outer wall is bent inclined downward to open to both sides, i.e., the inner wall 34 is formed upward from the base 31, and further extends downward from the upper end of the inner wall 34 to the vicinity of the base 31 ( The inner wall 34 and the outer wall 36 overlap each other in the vertical direction, and the shape thereof is complicated. On the other hand, the fastener extends the support arm 121a upward from the base 110. And a hook structure in which an upper portion of the support arm 121a is extended so that the flange 121b overlaps with the support arm 121a in the vertical direction, and the retaining arm 122 is extended from the flange 121b. By applying that The structure is simplified.

Therefore, in order to fabricate a complicated structure in which the conventional fixed inner wall 34 and the outer wall 36 are completely overlapped in the vertical direction, a process in the range of 18 to 25 is generally required to be performed by progressive press operations, Since the fastener has a simple structure, it usually requires a process ranging from 9 to 12, so that the manufacturing cost of the present fastener can be reduced as much as the number of processes reduced compared with the conventional fastener.

5 (a) and 5 (b) are schematic exploded views of a conventional fastener and a main fastener, respectively, and the width of the required metal plate of the conventional fastener ( W) and the width W 'of the required metal plate of the fastener are the same.

However, the length L of the required metal plate of the conventional fastener becomes longer than the length L 'of the required metal plate of the present fixture. That is, the length L = L₁ + 2L₂ of the required metal plate of the conventional fixture and the length L '= L'₁ + 2L'₂ of the required metal plate of the fixture are L 여기서 = L'₁ and L₂> L'₂. The length L of the required metal plate of the fixture is longer than the length L 'of the required metal plate of the fixture.

Therefore, the size of the metal plate required for manufacturing the fastener is smaller than that of the conventional fasteners, and thus the fastener can reduce the manufacturing cost corresponding to the size of the reduced metal plate compared with the conventional fasteners.
