Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the technical field of the shape structure of a retractable type decorative button attached to the skin of a cushion seat or the like of a car seat.

Therefore, this invention penetrates the pad of a cushion body such as a loose cushion seat type seat of the automobile, locks the outer skin to the head and pulls it in, and inserts a metal core material into the retainer on the back of the pad for interior reinforcement. This invention relates to a decorative button structure that can be retracted and used to hook the foot of the button.In particular, the head and foot are integrally molded with resin, the head is enlarged to facilitate skin locking, and the foot is made thinner. At the same time, it has a slightly thick hook at its tip that is hooked to the retainer, and a highly rigid metal core material is placed inside as a reinforcing material in the form of a rod from the hook through the foot part to the middle of the head. This invention involves a decorative button structure for the cushion body with increased strength and rigidity.

<Prior art> As is well known, vehicles such as automobiles are provided with a loose cushion seat type seat 1 as shown in FIG. A skin 3 as a cover sheet is attached to the pad 2 as a cushion body, and decorative buttons 4, 4... are provided at the setting part to draw the skin 3 into the pad 2. There is an embodiment in which the pad 2 is hooked to the back surface of the pad 2 to form a block-like loose cushion to improve the design appearance.

Conventionally, the manner in which the decorative button 4, which also serves as a seed drawer, is attached to the seat is as shown in FIG. A retractable string 7 is attached to the pad 11 in advance, and the string 7 is inserted through a hole 8 in the outer skin 3, and is also inserted through the button hole 10 of the pad 2 in the cover pad 9 to the back surface 12 of the pad 2 via the hook 11. It was designed to be latched onto the attached retainer 13.

However, the method of the seed-decorated button 4 has the disadvantage that it requires a lot of man-hours to attach, engage, and insert the retractable string 7, making the work cumbersome.Due to the strength of the string 7, the string may break during the work. There are disadvantages in that the lengths may be uneven, that is, the retraction may be uneven, and the operation requires skill.

<Problem that the invention aims to solve> To address this issue, an integrated metal button has been devised, but it has the disadvantage of being expensive and lacks a sense of harmony with the seat. Therefore, as shown in Figure 3,
An integrated decorative button 14 made of resin, as seen in the invention of Publication No. 10982, etc., has come to be used, but in this embodiment, the locking of the outer skin 3 is stabilized,
If the head 15 is made larger and the foot 16 is made thinner in order to facilitate insertion through the skin 3 and pad 2, there is a problem in that the strength and rigidity of the foot 16 decreases.On the other hand, if the foot 16 is made thicker Then, due to the insertion work, the hole in the epidermis 3 had to be made larger,
As a result, there was a risk that the buttonhole 8 would be torn or that the head 15 would be drawn into the pad 2 and fall down.

Furthermore, for example, as shown in British Patent No. 1492309, there is a mode in which a metal core material is interposed in the foot, but since the metal core is coiled, the rigidity is weak and the resin elasticity of the foot is low. In combination with this, flexibility was imparted to the feet, making it difficult to work.

The purpose of this invention is to solve the problem of decorative buttons that also serve as skin retractors for cushion bodies such as automobile seats, which are based on the above-mentioned prior art.
By making the head larger and the foot thinner, the button fulfills its original function as a decorative button, and the lack of strength and rigidity can be compensated for by the use of a metal core material, making it ideal for the automobile industry. It is an object of the present invention to provide an excellent decorative button structure for a cushion body that is useful in the field of automotive interior equipment technology.

<Means for solving the problem> In order to solve the above-mentioned problem, the structure of this invention, which is based on the above-mentioned claims for utility model registration, is based on the above-mentioned purpose. The outer skin is secured to the head, and the foot is secured to the back of the cushion body via a retainer, and the head and foot are integrally molded with resin, and a metal core material is interposed in the foot. The foot is sufficiently thin compared to the head, and a hook slightly thicker than the foot is formed at the opposite end of the head so that it can be freely engaged with the retainer. This is a decorative button structure of a cushion body in which a straight bar-shaped metal core material of high rigidity is integrally and reinforcingly inserted from the inside of the hook to the inside of the head.

<Function> When manufacturing decorative buttons, the head is made large, the foot with a large hook at the tip is made sufficiently thin and integrally molded with resin, and a highly rigid metal core material is cast from inside the hook to the inside of the head from the foot. Alternatively, the foot part can be integrally reinforced by insertion, etc., and the foot can be inserted through a small hole in the outer skin, and then the foot can be inserted through a button hole in the cushion body, and a hook can be hooked to a retainer on the back of the cushion body. A technical measure has been taken to retract it in a predetermined manner.

<Example> Next, an example of this invention will be described below based on the drawings from FIG. 4 onwards.

Note that the same parts as in FIGS. 1 to 3 will be described using the same reference numerals.

In the embodiment shown in FIG. 4, reference numeral 17 is a decorative button made of a predetermined resin, which forms the center of the gist of this invention. The head 18 is large and the mid-retraction foot 1 is used for
9 is thin, and the end hook 20 is sized according to the slightly thick design. From the hook 20 to the foot 19 and inside the head 18, a light metal core material 21 in the form of a rod with great rigidity such as aluminum is used as a reinforcing material and the resin of the exterior material is attached. It is injection molded and integrated into the casting.

In the decorative button 17 configured as described above, the foot portion 19 is inserted into the button hole 8 of the outer skin 3, and the hook 2 is inserted into the button hole 8 of the outer skin 3.
When the button hole 10 of the pad 2 is inserted through the button hole 10 of the pad 2 first, the large diameter head 18 sufficiently locks the skin 3, and the foot portion 19 is inserted through the button hole 10 and the pad 2 is inserted.
A retainer 13 of a predetermined shape attached to the back surface 12 of
The hook 20 is inserted into and hooked into the hook hole 22 through the elasticity of the teller 13.

The decorative button 17 set in this way is attached to the foot part 1.
9 is sufficiently thin, even if the button hole 8 in the skin 3 is small and the head 18 is large, the metal core material 21 can sufficiently lock and pull the skin 3 and provide strength during assembly and various operations.
The high rigidity ensures that no breakage occurs after the fact.

Further, in the embodiment shown in FIG. 5, after resin injection molding of the head 18' and foot part 19', a predetermined metal core material 21' is inserted into the hollow part. The effect is substantially the same as that of the above embodiment.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments; for example, the metal core material may be of a screw-in type, and the intended cushion body is not limited to automobile seats. A variety of options are possible, such as a 3-piece furniture set or wall coverings.

<Effects of the invention> As described above, according to this invention, the leg part is equipped with a hook at the tip that is latched to the outer skin of the cushion body, inserted through the cushion body, and latched to a retainer provided in contact with the back surface of the foot part. In this decorative button structure, which can also be used as a retractable button, the head is large and the foot is thin, integrally molded with resin, and a rod-shaped button extends from the hook on the bottom of the foot, through the foot, and halfway inside the head. By integrally incorporating a highly rigid metal core material, it is basically possible to lock the skin and insert it into the cushion body with one touch, and it is extremely easy to assemble. Not only during assembly, but also after assembly, even if the buttonholes in the skin are of small diameter, the buttonholes do not tear, and the head does not pull in or fall, providing an excellent effect.

In addition, even though the foot is thin, there is a highly rigid rod-shaped metal core inside the foot from the tip of the foot to the inside of the upper head.
The rigidity of the foot, the foot, the hook, and the neck between the foot and the head is sufficiently ensured, and there is no breakage due to handling during work, and it is easy to insert.

Furthermore, it is easy to mold, and because it is cast resin molded, it can be mass produced, and has the advantage of being low cost and lightweight.

In addition, resin molding has the advantage of being able to balance the color tone and combination with the epidermis, providing a good texture and satisfying aesthetic aspects.
