Description

Clips and Clip Connectors

[0001] The present invention relates to a clip and a clip connector for attaching a cover material to a cushion material.

[0002] In the past, seats and chairs have often been provided with cushioning on the seat surface, backrest, and other areas that come into contact with the human body, and the surfaces of these cushioning materials are covered with covering materials. Covering material attachment devices are known as a means for attaching covering materials to cushioning. For example, the covering material attachment device disclosed in Patent Document 1 includes clips embedded in the cushioning material and suspenders attached to the cushioning material, and the covering material can be attached to the cushioning material by engaging the suspenders with the clips.

[0003] International Publication No. 2018 / 186245

[0004] In the upholstery material attachment tool described above, a pulling force is applied from the upholstery material to the clip via the suspenders, and if this pulling force becomes excessive, the clip may come off the cushion material. For this reason, it is desirable to improve the fixing strength of the clip to the cushion material.

[0005] An object of the present invention is to provide a clip and a clip assembly that can improve the fixing strength to a cushion material.

[0006] (First Aspect) A clip according to the first aspect of the present invention comprises a sheet portion embedded in a cushioning material, and a clip main portion attached to the sheet portion and capable of engaging with suspenders attached to a cover material, the clip main portion comprising a base having an adhesive surface for bonding to the sheet portion, a pair of legs extending from the base and facing each other in the left-right direction, and a pair of claws attached to the pair of legs and protruding toward each other in the left-right direction, the left-right dimension of the sheet portion being greater than the left-right dimension of the adhesive surface of the base, and the left-right dimension of the adhesive surface of the base being smaller than the maximum outer dimension of the left-right dimension of the clip main portion defined by the pair of legs. In this configuration, the pair of claws of the clip main portion can engage with suspenders inserted between the pair of legs, allowing the sheet portion embedded in the cushioning material to closely contact the cushioning material. Furthermore, by setting the horizontal dimension of the adhesive surface of the base against the sheet, the maximum horizontal outer dimension of the clip body defined by the pair of legs, and the horizontal dimension of the sheet as described above, it is possible to ensure a large contact area of ​​the sheet body against the cushioning material around the clip body. This makes it difficult for the sheet to peel off from the cushioning material even when a pulling force is applied to the clip through the suspenders, and therefore the clip is unlikely to come off the cushioning material. This improves the fixing strength of the clip to the cushioning material.

[0007] (Second Aspect) In the clip according to the first aspect of the present invention, it is preferable that each of the pair of legs includes a first extension portion that extends upward from the base portion and extends away from each other in the left-right direction, and a second extension portion that extends upward from the first extension portion to the claw portion, and a space is formed between the first extension portion and the sheet portion into which a portion of the cushion material can fit. With this configuration, it is possible to ensure an insertion space for the suspenders between the pair of legs, while suitably ensuring a contact area of ​​the sheet portion with the cushion material around the periphery of the clip body.

[0008] In the clip according to the first or second aspect of the present invention, the left-right dimension of the seat portion is preferably two to three times the maximum left-right dimension of the clip body defined by the pair of legs. This configuration improves the fixing strength of the clip to the cushioning material while ensuring the strength of the cushioning material.

[0009] (Fourth Aspect) In the clip according to any one of the first to third aspects of the present invention, the sheet portion is preferably made of nonwoven fabric, and in this configuration, minute holes present in the nonwoven fabric constituting the sheet portion can suitably improve the adhesion of the sheet portion to the cushioning material.

[0010] (Fifth Aspect) A clip assembly according to a fifth aspect of the present invention includes a plurality of clips arranged in any direction as described in any one of the first to fourth aspects, and an elastically deformable clip connecting portion that connects the plurality of clips to one another. This configuration can achieve the same effects as the clips of any one of the first to fifth aspects. Furthermore, because the clip assembly has a seat portion for each clip, the overall shape of the clip assembly can be made to follow the shape (e.g., a curved shape) of the groove in the cushioning material by elastically deforming the clip connecting portion.

[0011] In the clip assembly according to the fifth aspect of the present invention, the sheet portions of the adjacent clips are preferably spaced apart from one another. With this configuration, the sheet portions of the clips are less likely to overlap with each other in various arrangements of the clip assembly, thereby maintaining favorable adhesion of the clips to the cushioning material.

[0012] Fig. 1 is a cross-sectional view showing an upholstery material attachment tool including a clip according to one embodiment of the present invention; Fig. 2 is a perspective view showing a clip assembly according to the embodiment; Fig. 3 is a side view showing a clip according to the embodiment; Fig. 4 is a perspective view showing a state in which the clip assembly according to the embodiment is bent; Fig. 5 is a schematic view showing a state in which suspenders are engaged with the clip according to the embodiment;

[0013] An embodiment of the present invention will now be described with reference to the drawings. As shown in Fig. 1, an upholstery material attaching device 1 according to this embodiment attaches an upholstery material 3 to a cushion material 2 for a vehicle seat or the like. This upholstery material attaching device 1 includes suspenders 4 attached to the upholstery material 3 and clip connectors 50 installed in grooves 21 in the cushion material 2, and the upholstery material 3 can be attached to the cushion material 2 by engaging the suspenders 4 with the clip connectors 50.

[0014] The cushion material 2 is a synthetic resin urethane foam material such as polyurethane foam molded into the shape of a seat. The cushion material 2 is formed with grooves 21 in which the clips 5 are installed. The grooves 21 form openings in the surface of the cushion material 2 and extend in any direction on the surface of the cushion material 2. The grooves 21 also form a pair of opposing side wall surfaces 211, 212 and a bottom surface 213 on the cushion material 2. The cover material 3 is a sheet that covers the surface of the cushion material 2 and is, for example, a synthetic resin woven fabric sheet. An edge portion 31 of the cover material 3 is attached to the suspenders 4 by sewing or the like.

[0015] The structure of the upholstery material attaching device 1 will be described with reference to FIGS. 1 to 3. In the following description of the structure of the upholstery material attaching device 1, three axial directions, X, Y, and Z, will be used, with reference to the state in which the suspenders 4 are fastened to the clip connectors 50 (see FIG. 1). For example, the length direction of the upholstery material attaching device 1 is defined as the X direction, the left-right direction of the upholstery material attaching device 1 as the Y direction, and the up-down direction of the upholstery material attaching device 1 as the Z direction. Note that, in a state in which the upholstery material 3 is attached to the cushion material 2 by the upholstery material attaching device 1 (see FIG. 1), the X direction corresponds to the length direction of the groove 21 in the cushion material 2, the Y direction corresponds to the width direction of the groove 21, and the Z direction corresponds to the depth direction of the groove 21. For ease of explanation, the direction toward one side (upward) in the Z direction is defined as the +Z direction, and the direction toward the other side (downward) in the Z direction is defined as the -Z direction, with the groove 21 opening in the cushion material 2 in the +Z direction.

[0016] 1, the suspenders 4 include attachment portions 41 to which the edge portions 31 of the upholstery material 3 are attached, and a suspender body portion 42 fixed to the attachment portion 41. In this embodiment, the attachment portion 41 is a sheet member such as a nonwoven fabric arranged along the XZ plane. The edge portions 31 of, for example, two sheets of upholstery material 3 are overlapped on the attachment portion 41, and the attachment portion 41 and the edge portions 31 of the upholstery material 3 are sewn together.

[0017] The suspender main body 42 has a base 421 in which the -Z side end of the mounting portion 41 is embedded, a pair of jig protrusions 422 provided on both sides of the base 421 in the Y direction, and a pair of engagement protrusions 423 provided on both sides of the base 421 in the Y direction on the -Z side of the pair of jig protrusions 422.

[0018] Each of the pair of jig protrusions 422 protrudes outward in the Y direction from the base 421, and forms a recess 422A that opens in the +Z direction between the base 421 and the protrusion 422. Any jig for operating the suspenders 4 can be inserted into this recess 422A. Each of the pair of engaging protrusions 423 protrudes outward in the Y direction from the base 421 on the -Z side of the jig protrusion 422, and together they form an anchor shape that engages with the clip 5.

[0019] In this embodiment, the suspender body 42 is a resin product that is injection molded using the attachment portion 41 as an insert. The suspender body 42 extends continuously or intermittently in the X direction so as to be engageable with each clip 5 of the clip assembly 50.

[0020] 2, the clip assembly 50 includes a plurality of clips 5 and a clip connecting portion 53 that connects the plurality of clips 5 to one another. Note that the following description will be based on the state in which the plurality of clips 5 are arranged along the X direction. Also, the following description will be given using one clip 5 as an example, but it is assumed that the other clips 5 have the same configuration.

[0021] 1, the clip 5 includes a sheet portion 51 embedded in the cushion material 2, and a clip body portion 52 that can engage with the suspenders 4 and is attached to the sheet portion 51. The configuration of the clip 5 will be described with reference to FIG.

[0022] The sheet portion 51 is a sheet member disposed along the XY plane. The specific material of the sheet portion 51 is not particularly limited, but is preferably a nonwoven fabric. The sheet portion 51 extends on both sides of the clip body 52 in the Y direction and is embedded in the cushion material 2 below the bottom surface 213 of the groove 21 of the cushion material 2 and on both sides of the groove 21 in the Y direction. Although not shown, the sheet portion 51 may have one or more through holes formed therein.

[0023] The clip main body 52 comprises a base 521 attached to the sheet portion 51, a pair of legs 522 standing upright from the base 521 and facing each other in the Y direction, and a pair of claws 525 provided on the pair of legs 522.

[0024] The base 521 is attached to a partial region of the surface 511 of the sheet portion 51 facing the +Z side. Specifically, the base 521 has an adhesive surface 521A that is adhered to the surface 511 of the sheet portion 51. Here, the Y-direction dimension W3 of the sheet portion 51 is larger than the Y-direction dimension W1 of the adhesive surface 521A of the base 521. Note that the method for adhering the base 521 to the sheet portion 51 is not particularly limited, and any adhesive can be used. That is, the adhesive surface 521A of the base 521 is adhered to the sheet portion 51 via an adhesive layer 54.

[0025] Each of the pair of legs 522 has a first extension 523 that extends from the base 521 in the +Z direction and outward in the Y direction (i.e., in a direction away from each other in the Y direction), and a second extension 524 that extends in the +Z direction from the first extension 523 to the claw 525. Here, the first extension 523 describes a curved shape that extends from the base 521 in the +Z direction and outward in the Y direction. The first extension 523 faces the sheet 51, and forms a space S between the sheet 51 into which a portion of the cushion material 2 can enter. Furthermore, in this embodiment, the maximum outer dimension W2 of the Y-direction outer dimensions of the clip main body 52 defined by the pair of legs 522 corresponds to the dimension between the Y-direction outer surfaces of the second extensions 524 of the pair of legs 522. Each of the pair of claws 525 protrudes inward in the Y direction and in the −Z direction from the tip of each of the second extensions 524 of the pair of legs 522. A gap is formed between the pair of claws 525 so that the suspenders 4 can be inserted therein.

[0026] In the clip 5 described above, the Y-direction dimension W1 of the adhesive surface 521A of the base 521 is smaller than the maximum Y-direction outer dimension W2 of the clip main body 52 defined by the pair of legs 522. In addition, in the clip 5, the Y-direction dimension W3 of the sheet portion 51 is preferably larger than the maximum Y-direction outer dimension W2 of the clip main body 52 defined by the pair of legs 522. Specifically, the Y-direction dimension W3 of the sheet portion 51 is preferably two or more times and three or less times the maximum Y-direction outer dimension W2 of the clip main body 52 defined by the pair of legs 522.

[0027] It should be noted that the X-direction dimension of each element of the above-described clip 5 can be set arbitrarily. As shown in FIG. 2, it is preferable that the X-direction dimension of the sheet portion 51 is approximately the same as the X-direction dimension of the clip main body portion 52.

[0028] The clip connecting portion 53 connects multiple clips 5 arranged in any direction. Specifically, the clip connecting portion 53 includes multiple base connecting portions 531 disposed between the bases 521 of adjacent clips 5, and a linear member 532 that continuously passes through the multiple clips 5 and the multiple base connecting portions 531. The base connecting portion 531 has a rod shape that extends along the X direction so as to connect the bases 521 of adjacent clips 5. The linear member 532 is, for example, a metal wire. By using the linear member 532 as an insert, the multiple clips 5 and the multiple base connecting portions 531 may be integrally injection molded.

[0029] In the clip assembly 50 described above, the clip connecting portion 53 has a certain degree of flexibility. For example, as shown in Fig. 4, by bending the clip connecting portion 53, it is possible to align a plurality of clips 5 along the bending direction.

[0030] (Method of Installing the Clip Connecting Body) An example of a method of installing the clip connecting body 50 of this embodiment on the cushion material 2 will now be briefly described. First, the clip connecting body 50 is set in a trench installed in a mold for the cushion material 2. This trench is a mold that forms the groove 21 of the cushion material 2, and is arranged at a position corresponding to the groove 21.

[0031] Next, the material of the cushion material 2 is injected into the mold for the cushion material 2 and foamed and solidified to form the cushion material 2. At this time, the material of the cushion material 2 fills the space around the clip assembly 50, including the space S of each clip 5.

[0032] Thereafter, the trench and the mold are removed from the cushion material 2. At this time, the area where the trench existed in the mold of the cushion material 2 appears as a groove 21. As a result, each clip 5 of the clip assembly 50 is placed in the groove 21, as shown in FIG.

[0033] (Upholstery Material Attachment Method) A method for attaching a skin material using the upholstery material attacher 1 of this embodiment will now be briefly described. First, the worker prepares the suspenders 4 with the upholstery material 3 attached and the cushion material 2 with the clip connectors 50 installed in the grooves 21, and places the upholstery material 3 so as to cover the cushion material 2. Then, the worker inserts the suspenders 4 into the grooves 21 of the cushion material 2, and applies pressure to the suspenders 4 in the -Z direction using any pressing means (such as a jig or automatic machine).

[0034] For example, when an operator uses a jig, the operator can apply pressure to the suspenders 4 in the −Z direction by inserting the jig into the recess 422A formed by one of the jig protrusions 422 on the suspenders 4 .

[0035] Alternatively, when any automatic machine is used, the operating part 71 of the automatic machine is inserted into the hole 22 formed in the bottom surface 213 of the groove 21 of the cushioning material 2 in an area corresponding to the gap between adjacent clips 5 (see FIG. 5). The operating part 71 then holds the jig protrusion 422 of the suspender 4 and can apply pressure to the suspender 4 in the −Z direction.

[0036] The suspenders 4 are pressed by any pressing means and pressed against the clip body 52 of each clip 5. The suspenders 4 are then guided by the pair of claws 525 while elastically deforming the pair of legs 522. When the pair of engaging protrusions 423 of the suspenders 4 are inserted between the pair of claws 525, the pair of legs 522 return to their original shape and the pair of engaging protrusions 423 engage with the pair of claws 525. At this time, each of the pair of claws 525 is inserted into the space between the jig protrusions 422 and the engaging protrusions 423 of the suspenders 4. In this way, the suspenders 4 are locked to the clips 5. This allows the upholstery material 3 to be attached to the cushioning material 2.

[0037] (Effects of this embodiment) As described above, the clip 5 of this embodiment includes a sheet portion 51 embedded in the cushion material 2, and a clip main body 52 engageable with the suspenders 4 attached to the cover material 3 and attached to the sheet portion 51, the clip main body 52 including a base 521 having an adhesive surface 521A with the sheet portion 51, a pair of legs 522 standing upright from the base 521 and facing each other in the left-right direction (Y direction), and claws 525 provided on the pair of legs 522 and protruding in directions in which they approach each other in the left-right direction (inward in the Y direction). The Y-direction dimension W3 of the sheet portion 51 is greater than the Y-direction dimension W1 of the adhesive surface 521A of the base 521, and the Y-direction dimension W1 of the adhesive surface 521A of the base 521 is smaller than the maximum outer dimension W2 of the Y-direction outer dimensions of the clip main body 52 defined by the pair of legs 522. In this configuration, the pair of claws 525 of the clip main body 52 can engage with the suspenders 4 inserted between the pair of legs 522, allowing the sheet portion 51 embedded in the cushion material 2 to closely contact the cushion material 2. Furthermore, by setting the Y-direction dimension W1 of the adhesive surface 521A of the base 521 relative to the sheet portion 51, the maximum Y-direction outer dimension W2 of the clip main body 52 defined by the pair of legs 522, and the Y-direction dimension W3 of the sheet portion 51 as described above, a large contact area of ​​the sheet portion 51 relative to the cushion material 2 can be ensured around the clip main body 52. ​​As a result, even when a pulling force is applied to the clip 5 via the suspenders 4, the sheet portion 51 is unlikely to peel off from the cushion material 2, and the clip 5 is unlikely to come off the cushion material 2. This improves the fixing strength of the clip 5 to the cushion material 2.

[0038] In this embodiment, the contact area of ​​the sheet portion 51 with respect to the base portion 521 is reduced, thereby ensuring a large contact area of ​​the sheet portion 51 with respect to the cushion material 2 around the periphery of the clip main body 52. ​​The adhesive strength of a typical adhesive is stronger than the adhesive strength of the foamed resin that constitutes the cushion material 2. Therefore, even if the contact area of ​​the sheet portion 51 with respect to the base portion 521 is reduced, the strength of the entire clip 5 is unlikely to be affected, and the fixing strength of the clip 5 can be improved without any problems.

[0039] In the clip 5 of this embodiment, each of the pair of legs 522 includes a first extension portion 523 that extends upward (toward the +Z side) from the base 521 and extends away from each other in the left-right direction (outward in the Y direction), and a second extension portion 524 that extends toward the +Z side from the first extension portion 523 to the claw portion 525, and a space S is formed between the first extension portion 523 and the sheet portion 51 into which a part of the cushion material 2 can fit. With this configuration, an insertion space for the suspenders 4 is secured between the pair of legs 522, and the contact area of ​​the sheet portion 51 with the cushion material 2 can be suitably secured around the clip main body 52.

[0040] In the clip 5 of this embodiment, the Y-direction dimension W3 of the sheet portion 51 is two or more times and three or less times the maximum outer dimension W2 of the Y-direction outer dimensions of the clip main body 52 defined by the pair of legs 522. In this configuration, the Y-direction dimension W3 of the sheet portion 51 is two or more times the maximum outer dimension W2 of the clip main body 52 defined by the pair of legs 522, thereby ensuring a sufficient contact area of ​​the sheet portion 51 with the cushion material 2. Furthermore, the Y-direction dimension W3 of the sheet portion 51 is three or less times the maximum outer dimension W2 of the clip main body 52 defined by the pair of legs 522, thereby ensuring the strength of the cushion material 2. If the Y-direction dimension W3 of the sheet portion 51 were greater than three times the maximum outer dimension W2 of the clip main body 52 defined by the pair of legs 522, the contact area of ​​the sheet portion 51 with the cushion material 2 would be even greater. However, when foaming the cushion material 2 around a sheet portion 51 of such size, much of the cushion material 2 is attracted to the sheet portion 51, which makes it easier for voids (air bubbles) to form in the cushion material 2. As a result, the strength of the cushion material 2 decreases. In this embodiment, rather than simply increasing the Y-direction dimension W3 of the sheet portion 51, the Y-direction dimension W3 of the sheet portion 51 is kept to no more than three times the maximum Y-direction outer dimension W2 of the clip main body 52 defined by the pair of legs 522, while ensuring the contact area of ​​the sheet portion 51 with the cushion material 2. This makes it possible to improve the fixing strength of the clip 5 to the cushion material 2 while ensuring the strength of the cushion material 2.

[0041] In the clip 5 of this embodiment, the sheet portion 51 is made of nonwoven fabric. In this configuration, minute holes present in the nonwoven fabric that forms the sheet portion 51 can suitably improve the adhesion of the sheet portion 51 to the cushion material 2.

[0042] The clip assembly 50 of this embodiment includes a plurality of clips 5 that can be arranged in any arrangement direction, and a clip connecting portion 53 that connects the plurality of clips 5 to one another and is elastically deformable. This configuration can achieve the same effects as the above-described clip 5. Furthermore, because the clip assembly 50 has a sheet portion 51 for each clip 5, the overall shape of the clip assembly 50 can be made to follow the shape (e.g., a curved shape) of the groove 21 of the cushion material 2 by elastically deforming the clip connecting portion 53.

[0043] In the clip assembly 50 of this embodiment, the sheet portions 51 of adjacent clips 5 are arranged with a gap between them. With this configuration, the sheet portions 51 of the clips 5 are unlikely to overlap with each other in various arrangements of the clip assembly 50, and therefore, the adhesion of each clip 5 to the cushion material 2 can be maintained in an appropriate manner.

[0044] (Modifications) In the above embodiment, a preferred range for the Y-direction dimension W3 of the sheet portion 51 is described, but the present invention is not limited to this. That is, the Y-direction dimension W3 of the sheet portion 51 can be set arbitrarily as long as it is greater than the Y-direction dimension W1 of the adhesive surface 521A of the base 521. Furthermore, the sheet portion 51 may be made of any sheet material such as fabric instead of nonwoven fabric.

[0045] In the clip assembly 50 of the above embodiment, each clip 5 has a sheet portion 51, but multiple clips 5 may share one sheet portion 51. Also, in the above embodiment, the clip assembly 50 in which multiple clips 5 are connected is described, but the multiple clips 5 may be used in a state in which they are individually separated.

[0046] In the above embodiment, the clip connecting portion 53 has a plurality of base connecting portions 531 and linear members 532, but the present invention is not limited to this. For example, the clip connecting portion 53 may not have a plurality of base connecting portions 531, but may be configured with a linear member 532 such as a wire. Alternatively, the linear member 532 may not have a linear member 532, but may be configured with a plurality of base connecting portions 531. Furthermore, the clip connecting body 50 may connect portions of the clips 5 other than the bases 521.

[0047] In the above embodiment, the first extension portion 523 of the leg portion 522 has a curved shape, but the present invention is not limited thereto. For example, the first extension portion 523 may have a linear shape extending from the base portion 521 in the +Z direction and outward in the Y direction. Furthermore, in the above embodiment, the maximum outer dimension W2 in the Y direction of the clip main body 52 defined by the pair of legs 522 corresponds to the dimension between the Y-direction outer surfaces of the second extension portions 524 of the pair of legs 522, but the present invention is not limited thereto. In other words, the maximum outer dimension W2 in the Y direction of the clip main body 52 defined by the pair of legs 522 may be the largest dimension between the Y-direction outer surfaces of any portion of the pair of legs 522.

[0048] In the above embodiment, the suspenders 4 are not limited to the configuration described above, and may have any configuration that engages with the clip connecting body 50 or the clips 5.
