Description

The present invention relates to a method for attaching a nameplate (nameplate) and an attachment used thereto. For example, the present invention is used to fix a nameplate on which a name, a trademark, etc. is printed or engraved to a member to be attached. In the following description, the mounting target is, but is not limited to, an automobile carpet or mat.

Conventional nameplates attached to automobile carpets and mats consist of metal plates (often made of aluminum) with 2 to 4 legs. The legs are pierced through a carpet or the like, and the exposed portion on the back of the carpet or the like is crimped with a washer to firmly fix the legs. For example, mounting methods and mounting tools as introduced in the following publications are known.

In the above-mentioned prior art (see FIG. 7 attached to the present application), the work of crimping the legs of the nameplate with a washer is performed in a state where the joint portion cannot be clearly seen from above and below the carpet or the like, although it is temporarily fixed. Furthermore, there is no way to confirm that the joining was done correctly even after the caulking work was completed. Therefore, while repeating the same type of work many times, not only basic mistakes such as forgetting to crimp are overlooked, but also poor joining (for example, tilted joining, center deviation, insufficient pressing force, etc.) are overlooked. There were many.

It is desirable that the protrusion of the nameplate is pressurized and pressed in the vertical axis direction in the hollow leg portion, and only the tip is enlarged in diameter and deformed enormously. However, as shown in FIG. 7, conventionally, the tip is often deformed in a distorted shape, and the base portion 12Y of the nameplate protrusion 12X is also often deformed. Further, as shown in FIG. 8, when the protrusion is subjected to pressure in an oblique direction, the protrusion 12X together with the hollow leg portion 12X collapses, and the tip of the protrusion does not expand in diameter and undergo enormous deformation, which may lead to caulking failure.

If you forget to crimp or have a poor connection, it is inevitable that the nameplate will come up or come off due to the passage of time or contact with the equipment. Such a thing would not lead to a major accident, but it would look bad and reduce the value of the car. On the other hand, it is difficult for ordinary users to reattach the nameplate from the inside of the car.

The present invention has been made in view of this problem, and provides a nameplate mounting method capable of easily and surely confirming whether or not the washer is accurately crimped to the leg, and a mounting tool used for the nameplate mounting method. The purpose is.

The method of attaching the nameplate of the present invention includes a step of preparing a nameplate in a state where protrusions are erected from the nameplate body, a step of preparing a washer having a head having a through hole in the center and a hollow leg portion, and the above-mentioned The step of penetrating the object to be mounted with the protrusion and temporarily fixing the washer on the back side of the object to be mounted, the step of crushing the tip of the protrusion via the head with a pressing tool, and the step of crushing the tip of the protrusion. It is a recess with a V-shaped cross section, and by visually recognizing whether the position of the center point at the lowest center of the recess is located at the center of the through hole, whether the tip of the protrusion is correctly expanded and greatly deformed. It is characterized by having a process of confirming whether or not .

Preferably, the tip of the protrusion is a recess having a V-shaped cross section, and the tip of the protrusion is correctly expanded in diameter and greatly deformed depending on whether or not the position of the center point at the center of the recess is located at the center of the through hole. (Claim 2).

In order to firmly crimp the nameplate to the washer, it is desirable that only the tip portion of the protrusion is greatly expanded in diameter and deformed (claim 3).

The nameplate attachment of the present invention has a nameplate in a state where a protrusion stands up from the nameplate main body, and a washer having a head having a through hole in the center and a hollow leg portion, and the tip of the protrusion has a cross section V. It is a dent of a character, and the lowest center of the dent is the center point, and the tip of the protrusion correctly expands from the through hole in a state where the nameplate and the washer are crimped through the mounting object. The feature is that it can be visually recognized whether or not the diameter is greatly deformed .

Preferably, the foot length of the hollow leg portion is set to a length equal to or shorter than the foot length of the protrusion within 3 mm (claim 5).

Preferably, the tip of the protrusion is a recess having a V-shaped cross section, and the lowest center of the recess is the center point (claim 6).

In order to improve the adhesion between the protrusion and the hollow leg portion before crimping, a raised portion may be provided on the outer wall of the protrusion (claim 7), or the cross section of the inner wall of the leg body in the hollow leg portion may be corrugated. (Claim 8). The washer having the head and the hollow leg is preferably an integral part (claim 9).

According to claims 1 and 4, the caulking operation is accurately performed by visually observing the central hole of the washer. For example, it can be confirmed whether or not the center point of the tip of the protrusion is located in the center of the central hole. This is because the center point is not located in the center of the central hole when it is not crimped correctly, and the center point seems to be far away when it is forgotten to crimp.

According to the inventions of claims 5, 7 and 8, the hollow protrusion of the washer firmly surrounds and reinforces the protrusion of the nameplate. As a result, the protrusion does not fall diagonally in the caulking process, and only the tip portion of the protrusion is correctly enlarged in diameter.

Hereinafter, examples of the present invention will be described with reference to the accompanying drawings.

It is a perspective view which looked at the nameplate 10 which concerns on 1st Embodiment of this invention from the back side. In the first embodiment of the present invention, (a) is a cross-sectional view in a temporarily fixed state, (b) is a cross-sectional view in a crimped state, and (c) is a schematic view showing the relationship between the nameplate leg and the washer leg.

In the third embodiment of the present invention, (a) is a cross-sectional view in a temporarily fixed state, (b) is a cross-sectional view in a crimped state, and (c) is a schematic view showing the relationship between the nameplate leg and the washer leg. It is sectional drawing which shows the conventional nameplate mounting method. It is sectional drawing which shows an example of the defective joining in which the protrusion of the nameplate and the hollow leg portion of a washer are tilted in the conventional nameplate mounting method. It is sectional drawing which shows the state which the defective product is detected by the method of this invention. It is a perspective view which looked at the nameplate 10C which concerns on 4th Embodiment of this invention from the back side. In the fourth embodiment of the present invention, (a) is a cross-sectional view in a temporarily fixed state, (b) is a cross-sectional view in a crimped state, and (c) is a schematic view showing the relationship between the nameplate leg and the washer leg.

FIG. 1 is a view of the nameplate 10 from the back side, and names and trademarks (not shown) are printed / engraved on the invisible side of the nameplate main body 11.

As can be seen from FIGS. 1 and 2, two protrusions 12 having a height of about 1 cm stand up from the nameplate main body 11. When the nameplate is made of aluminum, the protrusion 12 can be erected by sandwiching it between molds and applying pressure, so that the main body 11 and the protrusion 12 are integrally molded. The tip of the protrusion 12 has a V-shaped depression 14 having a maximum depth of 2 mm, and thus has a mortar shape. When the protrusion 12 is viewed from directly above, the center of the lowest V-shape of the depression 14 can be seen as the center point 17.

On the other hand, the washer 20 is composed of a head 21 and a hollow leg portion 22, and the end portion 23 of the leg portion that spreads toward the end is crimped and integrated by the head peripheral portion 24. A hole 25 having a diameter of about 2 mm is formed in the central portion of the head 21. As shown in FIG. 2C, the diameter L1 of the hollow leg body 26 of the washer is substantially the same as the diameter L2 of the protrusion 12. Therefore, by fitting the washer 20 to the protrusion 12, temporary fixing before caulking can be performed.

The foot length of the hollow leg portion 22 (H _{1 in} FIG. 2 (a)) is approximately the same as or shorter than the foot length of the nameplate protrusion 12 (H ₂ in FIG. 2 (a)) within about 3 mm. Yes, the one that is longer than the conventional one (h in FIG. 7) is used. As a result, the hollow leg portion 22 of the washer surrounds the protrusion 12 of the nameplate almost completely, so that it is temporarily fixed more stably. As a result, the roots of the protrusions are less likely to be deformed, and the protrusions and hollow legs are less likely to be tilted and joined.

FIG. 2A is a cross-sectional view of the nameplate body 11 and the washer 20 in a temporarily fixed state. After this, it will be officially crimped and fixed. As shown in FIG. 2A, the caulking operation is performed by crushing the tip recess 14 of the protrusion using the pressing tool 30. When the pressing tool 30 collides with the head, the tip of the recess 14 is greatly expanded in diameter and deformed. In the final state, as shown in FIG. 2B, only the tip of the recess 14 of the protrusion 12 is enlarged in diameter, and is enormously deformed so as to fill the inner hollow portion of the washer 20.

By this work, the nameplate 10 is firmly fixed to the carpet 40 and the like. The correct operation can be confirmed by visually observing the central hole 25 of the washer 20 and checking whether the tip center point 17 of the protrusion 12 is located in the center of the central hole 25. This is because the center point 17 is not located in the center of the central hole 25 when it is not crimped correctly, and the center point 17 seems to be far away when it is forgotten to crimp.

FIG. 9 is similar to FIG. 8 showing a conventional example, but shows a state in which a defective product is detected by the method of the present invention. In FIG. 9, since the tip center point 17 of the protrusion 12 is deviated from the center of the central hole 25, it can be easily visually confirmed that the protrusion 12 is not crimped correctly. In FIG. 8 (conventional example), it was judged whether or not the washer was defective only by the inclination of the washer 20X, so that it took skill to get used to it. On the other hand, in FIG. 9 (invention), since the judgment is based on whether or not the position of the center point 17 is deviated from the center of the central hole 25, even an inexperienced person can easily make an accurate judgment. ..

The only difference between Example 2 and Example 1 is that a plurality of raised portions 16A are provided on the wall of the protrusion 12A. For other parts similar to those in the first embodiment, "A" is added after the reference numeral used in the first embodiment, and the description thereof will be omitted.

The raised portion 16A is provided in order to improve the adhesion between the washer 20A and the protrusion 12A and temporarily fix it by the frictional force so that it can be stably crimped.

The effect of the central hole 25A of the washer 20A is the same as that of the first embodiment.

The difference between Example 3 and Example 2 is that the inner surface of the leg body 26B of the washer 20B has a corrugated cross section like a female screw. For other parts similar to those in the first embodiment, "B" is added after the reference numerals used in the first embodiment, and the description thereof will be omitted.

By forming the inner surface of the leg body 26B into a corrugated cross section, the adhesion between the washer 20B and the protrusion 12B is further enhanced, and stable caulking can be performed.

Since the inner surface of the leg body 26B does not have the original screw function, it does not need to have an accurate waveform like a female screw, and the leg is deformed into an uneven shape by compressing it from the vertical direction. It may be just about the same.

The effect of the central hole 25B of the washer 20B is the same as that of the first and second embodiments.

Comparing Example 4 with Example 1, the washer 20C is the same in that the head portion 21C and the hollow leg portion 22C are formed. In the first embodiment, the separate head portion 21 and the leg portions 22 are crimped and integrated, but in the fourth embodiment, these are only parts in an integrated state from the beginning. For other parts similar to those in the first embodiment, "C" is added after the reference numeral used in the first embodiment, and the description thereof will be omitted.

Needless to say, the action and effect of this example are the same as those of Examples 1 to 3.
