Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a button structure used in a so-called button-down seat, which has a design in which buttons are incorporated into the surface of the seat.

[Conventional technology]

Conventionally, three methods are known for forming button-down sheets: a spot quilt method, a clip method, and a thread sewing method. The spot quilt method is, as shown in FIG.
Then, the outer skin 23 is quilted by thread stitching or high frequency welding, and the inside of the quilting line 24 is made to look like a button 25. In this method, the green of the button 25 is connected to the surrounding skin 23 and the U-shaped quilting line 2.
Since it is continuous through 4, it tends to look poor. The clip method means that, as shown in FIG.
5, 36 and has a clip portion 37 on the back side, insert the button body 38 from the skin 33 side into each of the insertion holes 36, 35, 34 in order, and insert the clip into the washer 39 applied to the back side of the pad 31. Part 37
This is a method of hanging. In this method, the button body 38 is formed separately from the skin 33, so
The appearance is good enough, but when hooking the clip part 37 of the button and the washer 39, the button body 38 can be pushed in from the front side, and at the same time the washer 39
It is necessary to press the pad 31 against the back surface of the pad 31 from the back side, which is disadvantageous from the viewpoint of workability or productivity. The last thread sewing method is a method in which the button 42 is connected with a thread 43 to a locking member 41 formed of an S spring or the like disposed within the seat 40, as shown in FIG. Similar to the clip method, this method provides a sufficiently good appearance, but the work of threading the locking member 41 of the button 42 involves manually threading the thread 43 in several layers, and it is difficult to improve work efficiency. There are limits. Therefore, the inventors of the present invention developed a button-down seat button attachment structure that looks good and allows for highly efficient button attachment work. We devised a mounting structure that connects them. A hog ring is a ring made of wire that is used, for example, to connect a wire sewn into the periphery of the seat skin to a wire member provided at the bottom of the seat in order to stretch the skin of the seat. A C-shaped wire member is supported by a special fastening tool (hog ringer) that can be easily operated like a pistol, and the wire member is placed in a position surrounding the wire and the wire member to tighten the wire member. For example, the wire and the wire member can be joined by a simple operation that can be completed in a short time, such as pulling the trigger of the tool and crimping it into an annular shape. In this button attachment structure in which the button is attached to the seat using a hog ring, as shown in FIGS. A locking ring 53 to be connected is provided on the back surface of the button body 54. In this case, the pad 55, cover pad 56, and skin 57 of the seat 50 are pressed down from the front side, and a gun-type fastener (not shown) is used to support the C-shaped hog ring 52, and this hog ring 52 is attached to the button. The locking ring 53 and the locking line member 51 disposed within the seat 50 are positioned to surround each other, and the trigger of the crimping tool is pulled to tighten the locking line member 51 in an annular shape. This allows the locking ring 5 on the back of the button to
3 is the above-mentioned locking line member 51 via the hog ring 52
is multiplied by By the way, in such a button mounting structure, it has been found that if the locking hole of the locking ring 53 is formed to have a larger diameter than the hog ring 52, the button mounting workability can be further improved. Since it becomes easier to pass the hog ring 52 through the locking ring 53, the workability of stopping the hog ring itself is improved, and as a result, the workability of fastening the button is further improved. However, it has also been found that in such a case, the hog ring 52 becomes movable within the locking ring 53, which causes another problem as described below. That is, when a person takes a seat, the button is pressed down, but in this case, while the person is taking a seat,
As shown in FIG. 7b, the tip of the locking ring 53 temporarily comes into stable contact with the bottom of the hog ring 52, and then this stable state is broken due to some reason such as the movement of the seated person 58 and the second stop occurs. A state may be reached where the hog ring 52 engages the mid-height of the locking ring 53, as shown in Figure 7c, and thus passes from the stable state of Figure 7b to the maximum deflection state of Figure 7c. Occasionally, a noise that is unpleasant to the seated person is generated, and the seated person feels an unnatural feeling as if the seat is stuck in the middle of the sitting motion.

[Problems to be solved by the idea]

This invention was devised under the above-mentioned circumstances, and the problem to be solved was the button down, in which the button was attached to the seat using a hog ring, which the inventors devised prior to the invention. To provide a button structure for attaching a button to a seat so as to eliminate the occurrence of abnormal noise when sitting down and the feeling that a seated person is stuck in the middle of a sitting motion.

[Means to solve the problem]

The present invention takes the following technical measures to solve these technical problems. That is, the button structure of the present invention is a button structure of a button-down seat, which is provided with a locking ring on the back side of the button body, which is connected to a locking line member disposed inside the seat via a hog ring. ,
The locking ring has a locking hole formed with a larger diameter than the hog ring, and has a tip at the tip.
It is characterized in that a sharply protruding protrusion is provided so as not to stably abut against the hog ring.

[Functions and effects of the idea]

Since the locking ring has a locking hole larger in diameter than the hog ring, it is easy to pass the hog ring through it. Therefore, it becomes easier to perform the hog-locking work, and the workability of button-fastening is further improved. On the other hand, even if the locking ring of the button comes into contact with the hog ring while the seated person is sitting down, a sharp protrusion is provided at the tip of the locking ring to prevent it from stably contacting the hog ring. Because there are
The locking ring smoothly transitions to the maximum deflection state without stably abutting against the hog ring.
Therefore, there is no possibility that an abnormal noise will be generated while the seat is being seated, or that the seated person will not experience the sensation of being pinched during the seat motion. As described above, in the present invention, in a button mounting structure in which the button is fixed by connecting the locking ring provided on the back side of the button body to the locking line member via the hog ring, the locking hole of the locking ring is provided. By forming the lock hole to have a larger diameter than the hog ring, it is possible to further improve the workability of button fastening, while also solving the problems that arise when the locking hole is made to have a larger diameter than the hog ring.

[Explanation of Examples]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 3 is a perspective view of a button-down separate seat used for the driver's seat or passenger seat of a luxury passenger car. On the seat cushion 2 of this button-down seat 1, left and right pairs of buttons 3 are attached front to back, and on the seat back 4, left and right pairs of buttons 3 are attached vertically. For example, as shown in FIGS. 1 and 2, both buttons 3 on the front side of the seat 1 are located on both left and right sides of the left and right horizontally elongated grooves 6 formed by cutting out the upper surface of the pad 5 of the seat cushion 2. be located in A locking line member 7 made of an S spring or the like is attached to the pad 5.
is buried so as to be exposed at the bottom of the groove 6. The cover pad 8 that covers the upper surface of the pad 5 has a split groove 9 that extends from side to side along the upper side of the groove 6,
A skin 10 covering the upper side of the cover pad 5 is drawn in a U-shaped sleeve shape from between the grooves 9, and a wire 12 is inserted into the sleeve-shaped drawn-in cloth 11. This wire 12
to the above-mentioned locking line member 7 and hog ring 13
By engaging the locking wire member 7, an appropriate tension is applied to the skin 10. The button 3 includes a button main body 14 whose surface is covered with a skin of the same quality and color as the skin 10, and a lock that is integrally formed on the back surface of the button body 14 and is connected to the lock line member 7 via a hog ring 15. It consists of a ring 16. This locking ring 16 has a locking hole 16a that allows the hog ring 15 to pass through it easily.
It is formed to have a larger diameter than 5. Furthermore, a sharp protrusion 17 is provided at the tip of the locking ring 16 so as not to stably contact the hog ring 15. Note that a seam (not shown) connecting both the left and right buttons 3 in a horizontal line is formed above the portion of the skin 10 that is drawn into the groove 6, but this seam is covered to improve the appearance of the sheet 1. A belt-shaped flexible patch plate 18 is used to improve the appearance and give a luxurious impression. This patch plate 18 has buttons 3 on both left and right ends.
It has a button hole 19 through which a locking ring 16 is inserted and which is covered by the button body 14. The button 3 is attached, for example, according to the following procedure. That is, after the retractable cloth 11 is engaged with the hog ring on the locking line member 7, the retractable cloth 11 is
After covering the upper seam with the patch plate 18, attach the locking ring 16 of the button 3 to the button hole 19 of the patch plate 18 and the locking line member 7 peeking out from the split groove 9 of the cover pad 8. bring it closer,
The C-shaped hog ring 15 supported by a crimping tool (not shown) is connected to the locking line member 7 and the locking ring 16 of the button 3.
and is connected to the locking line member 7 via the hog ring 15 by pulling the trigger of the crimping tool and crimping and deforming the hog ring 15 into a circular shape. The sheet 1 to which the buttons 3 are attached in this manner has an excellent appearance similar to the conventional clip method or thread stitch method, since the buttons 3 are made separately from the outer skin 10. . Moreover, the button installation work is done only from the front side of the sheet 1, and the hog ring is supported by the swaging tool, positioned at the desired position, and then swaged by operating the swaging tool like scissors. This is a simple task that can be done in a short amount of time. Furthermore, by forming the locking hole 16a of the locking ring 16 to have a larger diameter than the hog ring 15, the workability of the hog ring stop itself is improved, so the work efficiency of button fastening is improved compared to the conventional method. It increases significantly compared to What should also be noted is that the locking ring 16 has a sharply protruding protrusion 17 at its tip to prevent it from stably contacting the hog ring 15, so when a person sits down, The tip of the retaining ring 16 is smoothly moved to the maximum deflection state without stably contacting the hog ring 15, and the hog ring and the retaining ring do not rub against each other and generate abnormal noises. This also eliminates the feeling of being poked while sitting down. Of course, the present invention is not limited to the one embodiment described above; for example, in the above embodiment, the protrusion was integrally formed on the locking ring, but a protrusion provided separately could be fixed to the locking ring. You may also do so. Furthermore, even if the protrusion is made to protrude sharply, it is also permissible to round the tip to an appropriately small diameter, as long as it can substantially avoid stable contact with the hog ring. .
