Description

  The present invention holds the fabric cover (including cotton, wool, polyester, acrylic, etc., leather such as cowhide, synthetic leather) covering the back of the chair itself and the cushion of the seat or the cushion attached to the chair. More particularly, the present invention relates to a button fastener for easily and detachably attaching a button for holding a fabric cover.

  In order to improve the sitting comfort of the chair itself such as a sofa, a cushion is integrated with the sofa itself, or the cushion is attached to the back or seat of the sofa. Sometimes. In many of these cushions, cushioning materials such as urethane foam, polyester cotton, feathers and the like having cushioning properties are covered with a fabric cover as the contents (filler). In this case, if the cushion material (filler) inside the cushion can move freely, the shape retention of the cushion will deteriorate, and the shape of the sofa will not be retained or the shape of the cushion will not be retained. There is not. For this reason, some places may be connected by a decorative button (case button) or the like in which the front and back surfaces of the cushion are connected by a string-like object (string, stretchable string or the like). Inside the cushion, the cushion material inside is held by a string-like material connecting the front surface and the back surface at several places, so that the shape of the sofa can be held, or the shape of the cushion can be held. In addition, decorating the front (and back) of the sofa or cushion with these decorative buttons in several places also leads to an increase in the design of the sofa and cushion.

By the way, in the sofa, the string-like material connecting the front surface and the back surface cannot be removed in many cases. If the surface is dirty, the cloth cover must be disassembled unless the sofa is disassembled and the string-like material is cut. Even if it can be selected, there is a problem that the fabric cover cannot be removed and washed.
In order to solve such a problem, it is conceivable to remove the dough cover for washing without disassembling the sofa when the surface becomes dirty by making the dough cover detachable. As a countermeasure when the surface of such a chair back or seat, pillow cushion, etc. is soiled, a covering method in which the cover (surface layer part) is removable and can be washed is generalized.

  Utility Model Registration No. 3195016 (Patent Document 1) is applied not to a sofa but to a cushion, and discloses a removable cover applicable to such a covering method. This detachable cover is cut in advance at a location corresponding to the button position of the buttoned cushion, and is provided with a button hole that is overlaid so that there is no fraying of the fabric around it. The detachable cover is detachably attached to a cushion with a button in which a filler such as urethane foam is wrapped with a cloth or the like and a button is attached to the surface thereof. When the detachable cover is attached to the cushion with a button, the button of the cushion with the button is put out from the back surface of the detachable cover to the surface of the detachable cover through the button hole. Thus, since the relationship between the cushion and the cover is integrated, the cushion fits well, and deformation due to misalignment during use is less likely (good shape retention).

Utility Model Registration No. 3195016

  However, the detachable cover disclosed in Patent Document 1 described above must be used in combination with a button-type cushion having a button on the surface. For this reason, there is a problem that versatility is low because a button must be attached to a cushion as a filler. Moreover, even if the shade of the detachable cover and the shade of the button of the cushion with buttons are matched (including when matching with the same shade or with different shades), if the detachable cover is changed, There is a problem that the color of the button may not match (becomes unpreferable in design), and in such a case, there is a problem that the button of the cushion with the button has to be replaced.

  The present invention has been developed in view of the above-described problems of the prior art, and the object of the present invention is to provide a covering cushion chair itself or a back cushion material or a seat cushion material to be attached to the chair. It is a fastener that fastens buttons that removably hold the covering fabric cover, and is versatile, inexpensive and detachable because various buttons can be used and there is no need to have buttons on the cushion (filler) To provide a button fastener for a removable cover that is easy to work with.

In order to achieve the above object, the button fastener of the removable cover according to the present invention employs the following technical means.
That is, the button fastener of the detachable cover according to the present invention is a resin clasp that fastens a button with legs that detachably holds a fabric cover that covers a cushion material of a covering-type chair itself or a cushion material attached to the chair. In a side view as seen from a direction parallel to the plane, the two flat plates and the two flat plates placed on the plane are connected to each other with their end faces facing each other with a predetermined gap therebetween. A substantially U-shaped connecting portion is integrally formed, and the flat plate or the connecting portion includes a locking portion that locks a hole provided in a leg portion of the legged button.

Preferably, the locking portion may be configured to be formed in a protruding shape on at least one of the substantially U-shaped surfaces facing each other in the connection portion.
More preferably, the connection portion is configured so that the substantially U-shaped open side protrudes from one surface of the flat plate and the substantially U-shaped bottom side protrudes from the other surface of the flat plate. The locking portion is formed integrally with the flat plate, and is formed in a substantially circular protrusion shape that engages with the hole portion on at least one of the substantially U-shaped open sides of the connection portion facing each other. Can be configured.

More preferably, the flat plate has a substantially semicircular shape, and is connected by the connection portion at a predetermined interval so that the diameters of the substantially semicircle faces each other, and the length in the diameter direction of the connection portion is It can be configured to be shorter than the diameter.
More preferably, the open end of the substantially U shape can be configured to be rounded.

  According to the present invention, various buttons can be used when fastening a button for detachably holding a covering cover chair itself or a fabric cover covering a back cushion material or a seat cushion material attached to the chair. It is possible to provide a button fastener for a detachable cover that is highly versatile, inexpensive, and easy to detach and attach, because it is not necessary to have a button on the cushion (filler).

The configuration of the object 400 and the back button 500) will be described.
・ Button fastener 100 (special item)
As shown in these drawings, the button fastener 100 is roughly composed of two flat plates 110 and two flat plates 110 placed on a plane with their end faces facing each other at a predetermined interval T ( 1) A connection portion 120 having a substantially U shape in a side view (see FIG. 4) viewed from a direction parallel to the plane, which is opened and connected, is integrally formed. And the connection part 120 is provided with the latching | locking part 130 which latches the hole 212 provided in the leg part 210 of the button 200 with a leg. The button fastener 100 is not particularly limited, but is made of a synthetic resin made of a polymer compound, and is made of, for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), or the like. When the button fastener 100 is formed of these resins, the substantially circular protrusions of the locking portions 130 are engaged (fitted) with the holes 212 provided in the leg portions 210 of the legged button 200 due to the elasticity of the resin. When the upper standing portion 126 of the connecting portion 120 expands due to elasticity and the substantially circular protrusion of the locking portion 130 engages (fits) in the hole portion 212, the upper standing portion 126 of the connecting portion 120 The legged button 200 is not easily detached from the button fastener 100 due to elasticity.

  Further, the connecting portion 120 is integrated with the flat plate 110 so that the substantially U-shaped open side protrudes from one surface of the flat plate 110 and the substantially U-shaped bottom side protrudes from the other surface of the flat plate 110. Is formed. The locking portion 130 is provided on at least one of the substantially U-shaped open sides of the connecting portion 120 facing each other (in the present embodiment, it is a double-sided but may be a single-sided button). It is formed in the shape of a substantially circular protrusion that engages with a hole 212 provided in the leg 210.

  Further, the flat plate 110 has a substantially semicircular shape, and is connected by the connection part 120 with a predetermined interval T (1) so that the diameters of the substantially semicircles are opposed to each other. L (2) or L (3) is shorter than the diameter L (1) of the substantially semicircle of the flat plate 110. Here, the diameter of the connecting portion 120 is L (2) or L (3) as shown in the middle of FIG. 3B, but in any case shorter than the diameter L (1). .

  Further, the end portion 128 on the open side 120U of the substantially U-shape of the connecting portion 120 has a rounded hemispherical shape. When the button fastener 100 is used repeatedly, if the leg portion 210 of the legged button 200 hits the upper standing portion 126 if it is not rounded, it may be cut out, whereas the end portion 128 Is rounded, such a notch does not occur even when the leg portion 210 of the legged button 200 hits the upper standing portion 126, which is preferable in terms of durability.

In general, the button fastener 100 according to the present embodiment having such a configuration will be described in more detail.
3A and 3B, the flat plate of the button fastener 100 is substantially semicircular, and has a predetermined interval so that the diameters of the semicircles are opposed to each other. Opening T (1) and penetrating the front and back of the flat plate 110 (as described above, the substantially U-shaped open side protrudes from one surface (here, the front side) of the flat plate 110, and substantially U-shaped. The bottom side of the shape is provided by a connection part 120 having a substantially U shape in a side view shown in FIG. 4 provided so as to protrude from the other side (here, the back side) of the flat plate 110.

  The connection portion 120 is substantially U-shaped so as to penetrate the front and back of the flat plate 110 in a side view, and the upper standing portion 126 of the connection portion 120 is provided on the surface 110F of the flat plate 110 so that the connection portion 120 is substantially omitted. The U-shaped open side 120U protrudes from the surface 110F of the flat plate 110, the substantially U-shaped bottom side 120D protrudes from the back surface 110B of the flat plate 110, and the connecting portion 120 is erected on the back surface 110B of the flat plate 110. By providing the portion 124, the substantially U-shaped bottom side 120 </ b> D of the connecting portion 120 protrudes from the back surface 110 </ b> B of the flat plate 110. The two lower standing portions 124 are connected by the bottom portion 122. In this case, the bottom portion 122 of the connecting portion 120 connects the two flat plates 110 with a gap T (1).

  As shown in FIG. 5A, the interval T (1) is slightly narrower than the thickness T (2) of the leg portion 210 of the legged button 200, and is made of a substantially U-shaped connecting portion 120 made of resin. The button fastener 100 is expanded so that the substantially circular protrusion of the locking portion 130 engages (fits) with the hole 212 provided in the leg portion 210 of the legged button 200. The legged button 200 is inserted into the.

At this time, the substantially circular protrusion of the locking portion 130 is easily engaged (fitted) to the hole 212 provided in the leg portion 210 of the legged button 200, and easily after engagement (fitting). The diameter D (1) of the substantially circular protrusion of the locking part 130 is slightly smaller than the diameter D (2) of the hole 212 provided in the leg part 210 of the legged button 200 so that it does not come off.
Thus, in addition to the material of the button fastener 100 itself being resin, the distance T (1) of the flat plate 110 in the button fastener 100 and the thickness T (2) of the leg portion 210 of the legged button 200 are as follows. The relationship between the diameter D (1) of the substantially circular protrusion of the locking portion 130 in the button fastener 100 and the diameter D (2) of the hole 212 of the leg portion 210 of the button 200 with a leg is established. Therefore, the substantially circular protrusion of the locking portion 130 is easily engaged (fitted) with the hole 212 provided in the leg portion 210 of the legged button 200, and the locking portion 130 is substantially circular with the hole 212. After the protrusions are engaged (fitted), the legged button 200 is not easily detached from the button fastener 100.

  Further, the diameter direction length L (2) or L (3) of the connecting portion 120 of the button fastener 100 is shorter than the diameter L (1) of the substantially semicircle of the flat plate 110. As described above, when the legged button 200 is fitted in the button fastener 100, the connection portion 120 is connected when the diameter direction length L (2) or L (3) (here, L (3) in particular) is long. The opening side 120U of the portion 120 is difficult to spread, and the legged button 200 is difficult to fit into the button fastener 100. On the other hand, when considering the strength of the button fastener 100 itself, if the length L (2) or L (3) (here L (2)) in the diameter direction of the connecting portion 120 is short, the bottom of the connecting portion 120 The strength of the bottom 122 connecting the two flat plates 110 on the side 120D is reduced, and the bottom 122 is damaged when the legged button 200 is fitted into the button fastener 100, or the legged button 200 is attached to the button fastener 100. When the leg portion 210 of the button 200 with the leg is applied with a force to widen the interval T (1) between the two flat plates 110, the bottom portion 122 is damaged and the button fastener 100 is damaged. There is a case.

  In order to realize the above-described conflicting actions, at least the diameter length L (2) or L (3) of the connecting portion 120 needs to be shorter than the diameter L (1) of the substantially semicircle of the flat plate 110. There is. Furthermore, the length L (2) or L (3) in the diameter direction of the connecting portion 120 is preferably 1/2 to 1/4 with respect to the diameter L (1) of the substantially semicircle of the flat plate 110. About 3 is particularly preferable.

  In addition, about the diameter direction length of the connection part 120, the length L (2) of the bottom part 122 of the substantially U-shaped bottom side 120D of the connection part 120 and the substantially U-shaped open side 120U of the connection part 120 are shown. There is a length L (3) of the upper standing portion 126. In this embodiment, L (2) ≈L (3), but the upper standing portion 126 often satisfies L (2)> L (3) due to the roundness of the end portion 128. In order to realize the above-described conflicting actions, it is also preferable to satisfy L (2)> L (3) in order to facilitate fitting of the legged button 200 while maintaining the strength of the button fastener 100 itself. In this case, L (1) >> L (2)> L (3).

  In addition, the cross-sectional shape of the upper standing portion 126 on the open side 120U of the substantially U-shaped connection portion 120 is a substantially circular shape with a distance T (1) between the two flat plates 110 (diameter is a substantially circular shape of L (3)). It is. This corresponds to the fact that the eyelet 310 described later forms a substantially circular dough hole 312 (diameter T (3)), and T (3)> L (3). However, since it may be a dough hole portion that does not use the eyelet 310 as will be described later, the cross-sectional shape of the upper standing portion 126 of the substantially U-shaped open side 120U of the connection portion 120 is limited to a substantially circular shape. It is not a thing.

As described above, the cross-sectional shape of the upper erected portion 126 is not limited to a substantially circular shape, but when the cross-sectional shape of the upper erected portion 126 is substantially circular, the present embodiment is implemented as shown in FIG. In the button fastener 100 according to the embodiment, the upper surface diameter D (3) is smaller than the lower surface diameter D (4) (this is a significant difference from the button fastener 900 according to a third modification described later). is there).
The structure of the general-purpose product used with the button fastener 100 having the above structure will be described with reference to FIGS.

・ General-purpose products (button 200 with legs, string-like object 400, back side button 500)
The button with legs 200 is not particularly limited, and is a general (case) button with legs used for clothing and furniture. As shown in FIGS. 5 to 7, the legged button 200 includes a substantially flat leg 210 that is erected near the center of the back surface of the main body 220, and the leg 210 is provided with a hole 212. ing. As described above, the legged button 200 is fitted into the button fastener 100 by engaging (fitting) the substantially circular projection of the locking portion 130 of the button fastener 100 with the hole 212.

  The back side button 500 is not particularly limited, and includes a configuration including only the bottom side of the button fastener 100, for example. As shown in FIGS. 5 and 6, this back-side button 500 is a plane that connects two substantially semicircular flat plates 510 placed on a plane with their end surfaces facing each other with a predetermined gap therebetween. A connecting portion 520 having a substantially U shape in a side view as viewed from a direction parallel to is integrally formed. However, although similar to the button fastener 100 in this respect, the back-side button 500 does not include the upper standing portion 126 (including its end portion 128) and the locking portion 130 of the button fastener 100.

  The string-like object 400 does not have general stretchability that connects the bottom 122 of the bottom 120D of the connection part 120 of the button fastener 100 and the bottom 522 of the connection 520 of the back button 500 in an endless loop shape. It is a string or a string-like object having elasticity. The string-like object 400 connects the button fastener 100 and the back button 500 in this way, and the back button 500 is a button having a leg part 210 having a hole 212 like the leg button 200. In this case, before the string-like object 400 is made into an endless loop, the string-like object 400 is passed through the hole 212 of the leg part 210 and then made into an endless loop, so that the button fastener 100 You may make it latch on the bottom part 122 of bottom 120D of the connection part 120. FIG. If it does in this way, the same button can be used in the front and back of the cushion 20 shown in FIG. Furthermore, from the viewpoint of using the same button on the front and back, a combination of the button fastener 100 and the button with leg 200 may be used one by one on the front side and the back side.

  The fabric cover 300 (the back fabric cover 12, the seat fabric cover 14, and the cushion fabric cover 22) has a string-like object corresponding to the position where the combination of the button fastener 100 and the button 200 with the leg is provided. A grommet 310 that forms a fabric hole 312 is provided at a position where the back side button 500 connected to the button fastener 100 via 400 is provided. The inner diameter of the eyelet (the diameter T (3) of the fabric hole 312) is at least a size through which the upper standing part 126 of the button fastener 100 and the leg part 210 of the legged button 200 pass, and the outer diameter of the eyelet. Is preferable in terms of design in that the eyelet 310 is not visible when the legged button 200 is engaged with the button fastener 100 by making it smaller than the maximum diameter of the main body 220 of the legged button 200.

However, the holes provided in the cloth cover 300 are not limited to those formed by the eyelet 310, but are holes formed by button holes, holes formed by thermal processing, and holes formed by tape processing. It doesn't matter.
[Attaching and removing fabric cover]
With reference to FIGS. 1 to 7 described above, a method for attaching and removing a detachable fabric cover using the button fastener 100 according to the present embodiment as described above. explain. In addition, as shown in FIG. 6, the urethane foam 600 provided with the cushioning property as a filler is provided between the front side fabric cover 300F and the back side fabric cover 300B.

Attachment Method As shown in FIGS. 5 and 7, the button fastener 100 and the legged button 200 are brought close to the fabric hole 312 formed by the eyelet 310 provided in advance on the front fabric cover 300 </ b> F. At this time, the string-like object 400 is passed through the bottom part 122 of the connection part 120 of the button fastener 100, and the string-like object 400 is passed through the bottom part 522 of the connection part 520 of the back button 500. Shall.

  In this manner, from the state in which the button fastener 100 and the button 200 with the leg are brought close to each other, the leg portion 210 of the button 200 with the leg is passed through the cloth hole 312 of the eyelet 310 (the substantially U shape of the button fastener 100). The upper standing portion 126 of the connecting portion 120 may be passed through the dough hole portion 312 of the eyelet 310), and the upper standing portion 126 of the substantially U-shaped connecting portion 120 of the resin button fastener 100 is widened. Thus, the substantially circular protrusion of the locking portion 130 is engaged (fitted) in the hole 212 provided in the leg portion 210 of the legged button 200. At this time, specifically, the leg portion 210 of the legged button 200 is pressed against the upper standing portion 126 of the substantially U-shaped connecting portion 120 of the button fastener 100 to widen the upper standing portion 126, The substantially circular protrusion of the locking portion 130 is engaged (fitted) with the portion 212. In this way, even if the legged button 200 is repeatedly attached to and detached from the button fastener 100, the leg 128 of the legged button 200 is rounded because the end 128 of the upper standing portion 126 is rounded. Even if the 210 is pressed against the upper standing portion 126, the notch does not occur.

  Accordingly, the state shown in FIG. 5 is changed to the state shown in FIG. 6, and the substantially circular protrusion of the locking portion 130 is engaged (fitted) with the hole portion 212, and the button 200 with the leg is connected from the button fastener 100. Does not come off easily. For this reason, since the button fastener 100 and the back side button 500 are connected via the string-like object 400, the button 200 with a leg, the button fastener 100, the string-like object 400, and the back-side button from the front side to the back side. 500 is connected, and the fabric cover 300 and the urethane foam 600 can be integrated.

-Removal method Basically, the fabric cover 300 can be removed from the urethane foam 600 in the reverse order of the attachment method.

-3rd modification With reference to FIGS. 10-12, the button fastener 900 which concerns on the 3rd modification of this Embodiment is demonstrated. 10A and 10B are two views of the button fastener 900, and FIG. 3A and FIG. 3B showing the three views of the button fastener 100. 11 corresponds to FIG. 4 showing a perspective view of the button fastener 100, and FIG. 12 (A) shows a state before the legged button 200 is engaged with the button fastener 100. FIG. FIG. 12 (B) and FIG. 12 (C) correspond to FIG. 6 which shows a state after the button 200 with the leg is engaged with the button fastener 100. Moreover, the lower stage of FIG. 10 (A) and FIG. 10 (B) is the figure which expanded partially the upper standing part 926 of the button fastener 100 in FIG. 10 (A) and FIG. 10 (B), respectively. 10 (A) and 10 (B), the button fastener 900 is rotated by 90 °, and the button fastener 900 is on the left and right sides in FIGS. 12 (B) and 12 (C). Is rotated 90 °.

  As shown in FIG. 10 and FIG. 11 (and FIG. 4 for comparison), in the button fastener 100, the upper surface diameter D (3) of the upper standing portion 126 <the lower surface diameter D (4) (lower) On the other hand, in the button fastener 900 according to the third modified example, the upper surface diameter D (3)> the lower surface diameter D (4) of the upper standing portion 926 is ( This is a characteristic configuration of a substantially frustoconical shape spreading upward.

  In other words, the button fastener 900 is roughly configured such that two flat plates 910 (corresponding to the flat plate 110) and two flat plates 910 placed on a plane face each other with a predetermined interval (T The connection portion 920 (corresponding to the connection portion 120) having a substantially U shape in a side view (see FIG. 11) viewed from a direction parallel to the plane is integrally formed. Has been. The connecting portion 920 includes a locking portion 930 (corresponding to the locking portion 130) that locks the hole portion 212 provided in the leg portion 210 of the legged button 200. In addition, the button fastener 900 includes an upper standing portion 926 corresponding to the upper standing portion 126 and an end portion 928 corresponding to the end portion 128 on the opening side 920U corresponding to the substantially U-shaped opening side 120U. The bottom side 920D corresponding to the substantially U-shaped bottom side 120D includes a bottom part 922 corresponding to the bottom part 122 and a lower standing part 924 corresponding to the lower standing part 124.

The upper standing portion 926 of the button fastener 900 has an upper surface diameter D (3)> a lower surface diameter D () as shown in the partial enlarged view of the lower stage of FIG. 10A and the lower stage of FIG. 4) and a shape having a height H (1).
The button fastener 900 is preferably used in combination with the eyelet 350 shown in FIG. The eyelet 350 has basically the same structure as the eyelet 310 used in combination with the button fastener 100. The inner diameter of the eyelet 350 (the diameter T (3) of the dough hole 352) is the same as the button fastener 900. The upper standing portion 926 and the leg portion 210 of the legged button 200 pass at least (diameter T (3)> upper surface diameter D (3) (> lower surface diameter D (4))), and more Specifically, the diameter T (3) is preferably slightly larger than the upper surface diameter D (3). As described above, since the diameter T (3) is slightly larger than the upper surface diameter D (3), the front surface 350F of the eyelet 350 is in contact with the rear surface 222 of the main body 210 of the legged button 200 as described later. In the state, the peripheral wall of the inner diameter of the eyelet 350 (the diameter T (3) of the dough hole 352) and the upper side of the upper standing portion 926 (the upper surface diameter D (3) side) face each other with a slight gap. Further, it is possible to suppress the upper side (upper surface diameter D (3) side) of the upper standing portion 926 from spreading.

  Further, although the thickness of the eyelet 310 used in combination with the button fastener 100 has not been described in detail, it is related to the hole 212 provided in the leg 210 of the legged button 200 as shown in FIG. The thickness is such that the substantially circular protrusion of the stopper 130 is engaged (fitted) so that the button 200 can be fitted into the button fastener 100. In addition to this, the eyelet 350 used in combination with the button fastener 900 has a thickness H (2). The thickness H (2) is smaller than the height H (1) at the upper standing portion 926 of the button fastener 900 (H (1)> H (2)).

Then, the upper surface diameter D (3), the lower surface diameter D (4) and the height H (1) of the upper standing portion 926 of the button fastener 900, and the inner diameter of the eyelet 350 (the diameter T (3 of the dough hole 352) )) And thickness H (2) are set so as to exhibit the following effects.
When attaching the button fastener 900 and the legged button 200, as shown in FIG. 12 (A), the button fastener 900 and the legged button 200 are attached by the eyelet 350 provided in advance on the front fabric cover 300F. It is made to adjoin to the formed dough hole 352. The method for attaching and removing the button fastener 900 and the legged button 200 is basically the same as the method for attaching and removing the button fastener 100 and the legged button 200 described above, but in the following points: In particular, the button fastener 900 is more preferable than the button fastener 100.

When attaching and removing the button fastener 900 and the legged button 200, the eyelet 350 is lowered in the direction of arrow D as shown in FIG. 12B, and the back surface 350B of the eyelet 350 is the surface 910F of the flat plate 910. It is made to contact with.
The height H (1) of the upper standing portion 926 provided with the locking portion 930 is larger than the thickness H (2) of the eyelet 350 (H (1)> H (2)), and the upper standing portion 926 The lower surface diameter D (4) of the eyelet 350 is smaller than the upper surface diameter D (3) of the upper standing portion 926 (D (3)> D (4)), so that the back surface 350B of the eyelet 350 contacts the surface 910F of the flat plate 910. When contacting, depending on the peripheral wall of the inner diameter of the eyelet 350 (the diameter T (3) of the dough hole 352), the upper side (upper surface diameter D (3) side) of the upper standing portion 926 is not suppressed. If it is not suppressed in this way, the upper standing part 926 of the substantially U-shaped connecting part 920 made of resin is expanded, and the locking part 930 is inserted into the hole part 212 provided in the leg part 210 of the legged button 200. The substantially circular protrusions can be easily engaged (fitted) or can be easily released (fitted). Thus, in order to make it easy to expand the open side 920U of the connecting portion 920, the legged button 200 can be easily fitted into the button fastener 900, or the fitting can be easily removed.

  When the button fastener 900 and the legged button 200 are attached in this way, the eyelet 350 is raised in the direction indicated by the arrow U as shown in FIG. 12C, and the surface 350F of the eyelet 350 is attached to the leg. It is made to contact | abut to the back surface 222 of the main-body part 210 of the button 200. FIG. Since the cushioning material 600 is narrowed down as shown in FIG. 1 or 2 (the string-like object 400 is shortened) and the legged button 200 is attached to the button fastener 900, it is a normal mode. In use, the eyelet 350 is usually raised by the swelling of the cushion material 600.

  The height H (1) of the upper standing portion 926 provided with the locking portion 930 is larger than the thickness H (2) of the eyelet 350 (H (1)> H (2)), and the upper standing portion 926 Since the lower surface diameter D (4) of the eyelet 350 is smaller than the upper surface diameter D (3) of the upper standing portion 926 (D (3)> D (4)), the surface 350F of the eyelet 350 is the main body of the legged button 200. When contacting the back surface 222 of 210, the upper side (upper surface diameter D (3) side) of the upper standing portion 926 is expanded by the peripheral wall of the inner diameter of the eyelet 350 (the diameter T (3) of the dough hole 352). It is suppressed. If restrained in this way, even if it is made of resin, the upward standing portion 926 of the substantially U-shaped connecting portion 920 does not spread, and the hole portion 212 provided in the leg portion 210 of the legged button 200 is engaged. The substantially circular protrusions of the engaged (fitted) locking portion 930 are unlikely to come off (do not come off). Thus, since the open side 920U of the connecting portion 920 is difficult to spread, the legged button 200 fitted in the button fastener 900 is difficult to be removed (not detached).

  The button fastener 900 according to the third modified example having such a configuration can exhibit the same function and effect as the button fastener 100, and the legged button 200 is attached to the button fastener 900 at the time of attachment. The button 200 with the leg fitted in the button fastener 900 is easily removed at the time of removal, or the button 200 with the leg fitted in the button fastener 900 is not easily detached (not removed) at the time of use. It is further preferable in terms of

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention is preferable for a button fastener for fastening a button for detachably holding a covering cover chair itself or a fabric cover covering a back cushion material or a seat cushion material attached to the chair, and various buttons can be used. In addition, the cushion (filler) does not need to have a button, so that it is highly versatile, inexpensive, and easy to attach and detach.
