Description

[Detailed Description of the Invention] The present invention relates to a seat button attachment device.

In general, seat buttons are attached to the back of the seat with their heads exposed on the front side of the seat cover, and function to add decorativeness to the seat, as well as to give the seat a three-dimensional feel. It functions to tension the sheet outer skin.

By the way, conventionally, in order to attach this type of button to a seat, the required number of retainers that lock the legs of the button are attached to the seat spring via C-rings, and the legs of the button are inserted into each of these retainers. A means of locking is taken. In reality, the attachment of the retainer and the insertion of the leg of the button are all done manually, and therefore a great deal of time is consumed in attaching the button.

The present invention was developed in light of these circumstances, and its main purpose is to create a completely new button mounting device that can securely mount a large number of buttons at once without having to adopt a very complicated structure. It is on offer.

Hereinafter, the present invention will be explained based on the drawings. FIGS. 1 and 2 show a first embodiment of the button attachment device according to the present invention. The button attachment device is designed to attach eight buttons at a time, and eight lower holders 10 are attached to the top surface of the table T in two rows in the left and right direction, each group consisting of four lower holders 10. Furthermore, eight pressing members 20 are attached to the lower surface of the base V, which is attached to the cylinder C and moves up and down, at portions facing each lower holder 10.

The lower holder 10 has a cylindrical main body 11 fixed to the upper surface of the table T, as shown in FIGS. 3 to 5.
, a rod-shaped receiving member 12 slidably inserted into the inner hole 11a of the cylindrical body 11, a pair of spring members 13 attached to the outer periphery of the cylindrical body 11, and each spring member 13. The first cam member 14 inserted between the cylindrical body 11 and the cylindrical body 11 and the receiving member 12
The second cam member 15 is inserted through the second cam member 15.

The cylindrical main body 11 is a cylindrical pressing part 2 of the pressing member 20.
An inner hole 11a that opens opposite to the inner hole 11a and extends in the axial direction.
a pair of concave grooves 11b extending in the axial direction on the front and rear surfaces of the outer periphery of the cylindrical body 11; a pair of slit-shaped grooves 11c extending in the radial direction at approximately the center of the front and rear outer periphery of the cylindrical body 11; Slit-shaped groove 11 in shaped body 11
A through hole 11d is provided slightly below c and extends in the same direction. A receiving member 12 is slidably inserted into the inner hole 11a of the cylindrical main body 11. The receiving member 12 includes a bowl-shaped receiving portion 12a at its tip, and a through hole 12b coaxial with the through hole 11d of the cylindrical body 11 at its lower end. It is supported by the inserted second cam member 15 and located in the inner hole 11a of the cylindrical main body 11. Further, the pair of spring members 13 have a band shape, and the cylindrical main body 1
It is attached in each groove 11b of 1 with screws 16. As a result, each spring member 13 is connected to each concave groove 11.
Each claw portion 13a provided at the tip of the tubular body 11 extends upward in the cylindrical body 11 in the inner radial direction at the tip opening of the cylindrical body 11. A pair of first cam members 14 inserted into each slit-shaped groove 11c of the cylindrical body 11 are interposed between each of these spring members 13 and the outer periphery of the cylindrical body 11.

Each of the first cam members 14 has a plate shape having approximately the same length as the left-right width of the table T, and is inserted into each of the slit-like grooves 11c of the group of four cylindrical bodies 11. Each of these first cam members 14 is formed with an outwardly wide wide portion 14a at a predetermined position, and when the wide portion 14a is positioned in the slit-like groove 11c by sliding in the length direction, each When the spring members 13 are pressed outward to widen the spacing between the claws 13a, and when the narrow portions 14b are located in the slit grooves 11c, the outward pressing force of each spring member 13 disappears. The gap between both claw portions 13a that has been expanded is reduced.
On the other hand, the second cam member 15, like the first cam member 14, has a rod shape with approximately the same length as the left and right width of the table T, and has a rod shape that extends through each of the group of four cylindrical bodies 11 and the receiving member 12. It is inserted into the holes 11d and 12b. This second cam member 15 has a large diameter portion 15a formed at a predetermined position, and by sliding in the length direction, the large diameter portion 15a moves into the through hole of the receiving member 12.
2b, the receiving member 12 is pushed up, and when the small diameter portion 15b is located in the through hole 12b, the pushed up receiving member 12 is lowered. Both of these cam members 14, 15 have a wide portion 14a and a large diameter portion 15a.
are connected to the operation lever 17 with the two being offset from each other, and slide in conjunction with the rotation of the operation lever 17. They are located alternately in the groove 11c and the through hole 12b of the receiving member 12.

In the button mounting device configured in this way,
Each lower holder 10 is in the state shown in FIGS. 3 to 5. That is, the wide portions 14a of the pair of first cam members 14 are located within each slit-like groove 11c and press the pair of spring members 13 outward, thereby widening the gap between the claw portions 13a. ing. Further, the small diameter portion 15b of the second cam member 15 is located within the through hole 12b of the receiving member 12, thereby lowering the receiving member 12. Therefore, in this state, the cylindrical body 1
The opening at the tip of button 1 is completely open, and the button B is inserted into the opening by pinching its leg _b1 . Next, when the operating lever 17 is rotated,
Both cam members 14 and 15 slide to the left in the first figure. As a result, as shown in FIG. 6 and FIG. At the same time, the small diameter portion 15b of the second cam member 15 is still located within the through hole 12b of the receiving member 12. Therefore, the distance between the claws 13a of the spring member 13 is reduced so that the claws 13a face the opening at the tip of the cylindrical body 11. When the operating lever 17 is further rotated to further slide both cam members 14 and 15 to the left in the first drawing, each slit-shaped groove of the cylindrical member 11 is moved as shown in FIGS. 8 and 9. 11c
The narrow width portions 14b of both first cam members 14 are located within, and the large diameter portion 15a of the second cam member 15 is located within the through hole 12b of the receiving member 12.
Therefore, the receiving member 12 is pushed upward, and the button B is pressed from the head b ₂ side to the lower surface of both claw portions 13a of both spring members 13. As a result, the button B is accurately positioned by the receiving part 12a and both claw parts 13a of the receiving member 12, and the leg part b ₁ of the button B is
protrudes upward accurately.

After completing the above work, place a large number of lower holders 1
The outer skin s ₁ of the back S of the seat and the molded pad s ₂ serving as the inner material are placed on the seat in the state shown in FIG. 10, and the leg b ₁ of the button B is made to protrude. On the other hand, on the lower surface of the base V of the cylinder C, a leather s ₃ with a number of retainers R corresponding to the buttons B is attached so that each retainer R faces the cylindrical pressing part 21 of each pressing member 20, and then the cylinder C is operated forward to lower the base V. As a result, the retainer R is pressed against the upper surface side of the lower holder ₁₀ with its upper cylindrical part r1 inserted into the inner hole 21a of the cylindrical pressing part 21, and the leg part _b1 of the button B is pressed against the retainer R. It fits securely into the locking hole _r2 . As a result, eight buttons B are attached at once by the forward movement of cylinder C. Finally, when the cylinder C is operated backward to raise the base V and the operating lever 17 is rotated in the opposite direction, both cam members 1
4 and 15 return to the state shown in FIGS. 4 and 5, the tip opening of the lower holder 10 is completely opened, and the back part S of the seat can be removed from each lower holder 10. If the back part S of the seat is removed from each lower holder 10, the work of attaching the button B is completed.

As described above, according to the button attaching device, a large number of buttons B can be attached at once with a relatively simple configuration, and even if the buttons B are inserted into the inner hole 11a of the cylindrical body 11 of each lower holder Even if the button B is inserted in a tilted state, the button B is accurately positioned by the receiving member 12 and both claws 13a of both spring members 13, so no skill is required to insert the button B. And it can be done in a short time. In addition to accurately positioning the button B, since the button B and the retainer R are pressed and locked between the lower holder 10 and the pressing member 20, the button B will not be damaged in any way. It can be installed securely and firmly without any problems.

FIG. 11 shows a second embodiment of the button attachment device according to the present invention. In this button mounting device, the base V on which the pressing member 20 is mounted is connected to the arm A rotatably mounted on the rear of the table T.
Fixed. This arm A has a cylinder C.
are connected to each other, and when the cylinder C moves forward, the base V rotates together with the arm A as shown by the temporary phase line in the figure, and when the cylinder C moves backward, the base V rotates as shown by the solid line in the figure. Other configurations are
This is exactly the same as the first embodiment.

In addition, in the present invention, the number of lower holders 10 and pressing members 20 in the above embodiment can be increased or decreased as necessary, and both cam members 1
4 and 15 into the slit-like groove 1 of the cylindrical body 11.
1c, and the relationship with the through hole 12b of the receiving member 12 can be changed as appropriate.

As explained above, the present invention includes a lower holder that accurately positions and receives the button;
Since it uses a pressing member that presses the retainer that locks the leg of the button toward the lower holder, if you use the desired number of these lower holders and pressing members, you can create a large number of them in a short time and without any skill. buttons can be installed accurately and firmly at once. Moreover, such an effective button attachment device can be provided with a relatively simple construction.
