Description

  The present invention relates to a fastener, and more particularly to a fastener for fastening an attachment component such as a plate material to an attachment portion that is a wall or a vehicle body.

  Conventionally, there is a need to connect or fix one object to another in a scene where various articles are manufactured, but it is generally performed using nails, screws, or adhesives. . However, there are many articles and scenes where these nails, screws, or adhesives cannot be used, and special fasteners are required for articles and scenes where these nails, screws, etc. cannot be used. For example, there is a method or fastener suitable for fastening a mounting part such as a plate material that does not want to be scratched or processed on a mounting part that is a wall or a vehicle body having no work space on the back side, for example, Patent Document 1 etc. have been proposed variously.

  As shown in FIGS. 6 and 7, the “fixing structure of the detachable member” proposed in Patent Document 1 is as follows: “The body 1 to be attached / detached is formed with a counterbore 1 a and on the bottom face of the counterbore, A saddle-shaped through hole 1b in which the small-diameter portion 1b1 is positioned is formed in the substantially central portion of the detachable member 2. A mushroom-shaped support shaft 2a is formed on the detachable member 2, and a male screw portion 2a3 is formed on the shaft portion 2a2. Then, a screw knob 2b is screwed in. After the cap portion 2a1 of the mushroom-shaped support shaft 2a is inserted into the daruma-shaped through-hole large-diameter portion 1b2, the shaft portion 2a2 is inserted into the daruma-shaped through-hole small-diameter portion 1b1. And the screw knob 2b is tightened so that the screw knob 2b is accommodated in the counterbore part 1a and the bottom face of the counterbore part 1a is sandwiched from the front and back by the cap part 2a1 and the screw knob 2b. It is “fixed”.

  In the “fixing structure of the detachable member” proposed in Patent Document 1, “the barrel portion 2a1 of the mushroom-shaped support shaft 2a is inserted into the daruma-shaped through-hole large-diameter portion 1b2, and then the shaft portion 2a2 is inserted into the dar- It is necessary to move it into the small hole diameter portion 1b1 and tighten the screw knob 2b ", and also a space for performing this tightening operation.

  Therefore, Patent Document 2 proposes a technique that eliminates the need for these tightening operations and spaces.

Japanese Patent Laid-Open No. 10-184629, abstract, representative diagram Japanese Patent No. 2860341, FIG. Japanese Patent Laid-Open No. 07-133812 Patent No. 5048263 Japanese Patent No. 5210329 No. 03-036438

  In Patent Document 2, as shown in (a) of FIG. 8, “a head for sandwiching and holding an object to be held, and a body for inserting into a mounting hole of a panel plate and fitting. And a holding clip in which the body portion includes a pair of elastic legs and a central column portion has been proposed. This “holding clip” (indicated by reference numeral 40 in FIG. 8A), as shown in FIG. 8A, is a series of large holes 51 and small holes 52 formed in the plate material 50 to be attached. The head is inserted into the large hole 51 out of the Dalma holes continuous at the portion 53, and the shaft of the holding clip 40 is transferred to the small hole 52 through the continuous portion 53 as it is. The head of the clip 40 is fitted.

  As a result, the holding clip 40 can fix the plate member 50 to the insertion hole 54a of the iron plate 54 to be attached, but a problem occurs in the attached plate member 50. That is, when the surface of the plate member 50 (the right side surface in FIG. 8A) is used as it is, the large hole 51 used only for inserting the head is exposed to the surface as it is. It is to do. When the plate member 50 is fixed to the insertion hole 54a of the iron plate 54 by the holding clip 40, it is considered that the state shown in FIG.

  In the state shown in FIG. 8B, the large hole 51 used only for inserting the head of the holding clip 40 is exposed on the surface, and the exposed large hole 51 is formed by the plate material 50. When it is a cover material, it not only looks very bad, but other things are caught in the large hole 51 and dust is collected, which makes the product very inconvenient. Therefore, conventionally, in order to hide the large hole 51, after attaching the holding clip, it is necessary to perform a troublesome work of attaching a decorative material such as a nonwoven fabric or a leather sheet to the plate material on the head side of the holding clip. doing.

  By the way, when using this type of clip to attach an attachment part to an attachment part that is an attachment object, a clip in which the length of the “shaft” is adjusted according to the thickness of the attachment part is required. In other words, when a thin component such as a sheet-like cover material or solid plate material is a mounting part, a clip with a short “shaft” is used, and plastic corrugated cardboard or the like (having a harmonica-like cross section) If the material is thick like a hollow structure plate in (), a clip with a long "shaft" will be used, and a clip corresponding to the type and thickness of the mounting part must be prepared. . If the length of the “shaft” of the clip changes, it is necessary to perform a strength test on the clip itself and its “shaft”, and it takes a lot of time and labor to prepare a clip according to the type of mounting part. become.

  The length of the shaft of a general clip is short because it matches the thickness of a solid plate material. However, the thickness of a hollow structure board such as plastic corrugated cardboard is thicker than that of a solid board, and it is difficult to attach a general clip having a short shaft length. To attach a clip with a short shaft length, it is possible to attach the clip by pressing the hollow structure plate to reduce the wall thickness, but even if the clip is attached to the hollow structure plate There is a fear that the pulling strength is insufficient and the clip is detached from the hollow structure plate.

  Accordingly, when the present inventors use the holding clip 40 to fix the plate member 50 to the insertion hole 54a of the iron plate 54 to be attached, the large hole 51 is exposed on the surface of the attached plate member 50. As a result of various studies on how to eliminate the need to prepare clips according to the type and thickness of mounting parts, the present invention has been completed. It is.

That is, the object of the present invention is that the attachment part can be fastened to the attachment part via the clip, and it is not always necessary to prepare a clip according to the type and thickness of the attachment part. The clip can be used, and it is not necessary to form a “dar hole” for locking the clip on the mounting part, and when the fastening is completed, there is an “opening” like a large hole that constitutes the dull hole. It is an object of the present invention to provide a fastener that can be prevented from remaining on the surface of a mounting part.

In order to solve the above-mentioned problem, the fastener according to claim 1 of the present invention is configured so that the head portion of the clip is attached to the attachment portion via the clip accommodated in the opening of the attachment component. A fastener provided with a main body part that accommodates and holds the main body part, the main body part being formed so as to be able to be accommodated in an opening of the attachment part, and an umbrella part supporting the periphery of the opening of the attachment part, Furthermore, the side wall of the main body has an insertion opening through which the head of the clip can be inserted into the main body, and the bottom wall of the main body has an axis that supports the head. A long hole is provided for guiding and accommodating the head in the main body.

According to the said characteristic, an attachment component can be fastened to an attachment part via this clip by inserting the head of a clip from an insertion opening, and accommodating in a fastener. Furthermore, there are various methods for inserting the clip head from the insertion opening. For example, the clip is pushed up by deforming the umbrella portion of the fastener located around the opening of the attachment part. Then, since the insertion opening of the fastener can be protruded from the opening of the mounting part, the head of the clip can be easily inserted into the protruding insertion opening.

Further, if the mounting part is a hollow structure plate such as a plastic corrugated cardboard, the wall portion of the hollow structure plate itself is thin, so that it can be appropriately recessed with respect to external pressure. Moreover, even if it is a hollow structure board other than the above, if the material has a softness | flexibility, it can be dented moderately with respect to the pressure from the outside. Therefore, the head of the clip can be easily inserted into the insertion opening by denting the periphery of the opening of the attachment part with the head of the clip and exposing the insertion opening of the fastener.

Further, the opening of the attachment part for attaching the fastener is not a “dar hole” as in the prior art, and furthermore, since the opening of the attachment part is concealed by the umbrella part of the fastener, the attachment part is particularly a cover material. In such a case, it is not necessary to attach a decorative material such as a nonwoven fabric or a leather sheet to the opening as in the conventional case, so that it does not take time and does not impair the appearance of the mounting part.

Conventionally, since the head of the clip is directly fitted and held in the opening of the attachment part, it is necessary to adjust the length of the shaft of the clip according to the type and thickness of the attachment part. However, according to the present invention, since the clip is indirectly held by the attachment part via the fastener, the clip is accommodated and held in the fastener regardless of the type and thickness of the attachment part. Therefore, it is not necessary to adjust the length of the clip shaft as in the prior art, and a general clip can be used as it is.

Furthermore, the fastener according to claim 2 of the present invention is characterized in that a constricted portion for narrowing the width of the long hole is provided in the long hole.

According to the said characteristic, it can prevent that the clip accommodated in the fastener falls out carelessly outside through a long hole by the constriction part which narrows the width | variety of a long hole.

The fastener of the present invention can always use a general clip without having to prepare a clip according to the type and thickness of the mounting part, as well as being able to fasten the mounting part to the mounting part via the clip. There is no need to form a “dar hole” for clip locking on the mounting part, and when the fastening is completed, an “opening” like a large hole that constitutes the dull hole is formed on the surface of the mounting part. It can be made not to remain.

DESCRIPTION OF SYMBOLS 100 Fastener 110 Main body part 111 Side wall 112 Bottom wall 120 Insertion opening 130 Long hole 160 Umbrella part 200 Attachment part 210 Opening 300 Attachment part 310 Fastening hole 400 Clip 410 Head 420 Axis

Embodiments of the present invention will be described below with reference to the drawings.

First, FIG. 1 shows an example of how the fastener 100 of the present invention is used. The fastener 100 is used to fasten a mounting part 200 such as a plate material to a mounting part 300 that is a part of a wall or a vehicle body via a clip 400. Specifically, first, the main body 110 of the fastener 100 is inserted into the opening 210 from the front side (the front side in the drawing) of the attachment component 200. As will be described in detail later, the head 410 of the clip 400 is inserted into the insertion opening 120 of the main body 110, and the head 410 is accommodated and held inside the main body 110. Then, the clip 400 is accommodated in the opening 210 via the fastener 100 and fixed. Next, the attachment part 200 is fastened to the attachment part 300 via the clip 400 by inserting the main body part 430 of the clip 400 integrated with the attachment part 200 into the fastening hole 310 of the attachment part 300.

Incidentally, the clip 400 is generally used and commercially available, and there are various types. Basically, as shown in FIG. 1 and FIG. 100, the head 410 held in the main body 110), the shaft 420 integral with the head 410, and the tip of the shaft 420 are integrated into the fastening hole 310 of the mounting portion 300. The entire body 430 is integrally formed of synthetic resin or the like. In addition, this type of clip 400 generally has an abutting portion 440 that abuts against the surface of the attachment portion 300 and prevents further insertion of the main body portion 430.

Further, the head 410 of the clip 400 is used only for housing in the main body 110, and the shaft 420 is used only for insertion into the long hole 130 and the bearing hole 113 (see FIGS. 2 and 3). Therefore, the cross-sectional shape may be a square or another shape. However, since the directionality at the time of insertion is lost, it is preferably a “circle”.

Next, the configuration of the fastener 100 of the present invention will be described in detail with reference to FIG.

As shown in FIG. 2A, the fastener 100 includes a cylindrical main body 110 and a flat thin plate-like umbrella 160 having a substantially circular shape in plan view. In the main body 110, the back surface of the umbrella portion 160, the side wall 111, and the bottom wall 112 form a storage portion 114 that can store the head portion 410 of the clip 400. An insertion opening 120 for inserting the head portion 410 of the clip 400 into the main body 110 is provided in a part of the side wall 111. The insertion opening 120 opens to the side of the main body 110 and communicates with the internal storage portion 114. The height H1 (see FIG. 2D) can be inserted into the head 410. Further, it is set to be equal to or greater than the maximum height of the head 410, and the width L1 is set to be equal to or greater than the maximum width (diameter) of the head 410. Since the fastener made of synthetic resin has a certain degree of flexibility, the head 410 can be inserted even if the width L1 is the same as or smaller than the maximum width (diameter) of the head 410.

The bottom wall 112 of the main body 110 is provided with a long hole 130 that extends from the outer peripheral edge of the bottom wall 112 to the bearing hole 113 in the center of the bottom wall 112. The long hole 130 communicates with the insertion opening 120. Therefore, the long hole 130 can guide the shaft 420 supporting the head 410 to the center bearing hole 113 of the main body 110 when the head 410 of the clip 400 is inserted into the insertion opening 120. it can.

Thus, since the long hole 130 and the bearing hole 113 guide and accommodate the shaft 420 of the clip 400, the maximum width (diameter) L2 of the bearing hole 113 is the shaft 420 as shown in FIG. The width L3 of the long hole 130 is set to be equal to or greater than the maximum width (diameter) of the shaft 420. Since the fastener made of synthetic resin has a certain degree of flexibility, even if the width L3 is the same as or smaller than the maximum width (diameter) of the shaft 420, the shaft 420 can be guided and accommodated.

Here, in the present embodiment, the narrow portions 150 are provided at both ends of the long hole 130 so that the width L3 of the long hole 130 is narrower than the width L2 of the bearing hole 113. That is, by narrowing the width of the long hole 130 by the constricted portion 150, the shaft 420 accommodated in the bearing hole 113 is not easily pulled out from the long hole 130, and the accommodated clip 400 is not removed from the fastener 100. It prevents it from falling off easily. In addition, the shaft 420 of the clip 400 may be easily inserted by forming a chamfer at the tip of the constricted portion 150.

Further, as shown in FIG. 2F, the back surface side of the constricted portion 150 is an inclined surface 151 that is inclined from the inlet side of the insertion opening 120 toward the accommodating portion 114 of the main body 110. Further, as shown in FIG. 2 (e), the inclined surfaces 151 on both sides are gradually narrowed toward the bearing hole 113, so that the boundary with the bottom wall 112 is substantially C-shaped. The step portion 152 spreads in a shape. The maximum width L4 between the inclined surfaces 151 on both sides is set to be equal to or greater than the maximum width (diameter) of the head 410 of the clip 400. As will be described in detail later, when the head 410 is inserted into the insertion opening 120, a portion with which the head 410 abuts becomes an inclined surface 151. Therefore, the inclined surface 151 is inclined toward the accommodating portion 114, and the stepped portions 152 on both sides are substantially C-shaped so that the width is narrowed toward the accommodating portion 114. The head portion 410 that is in contact with the surface 151 is easily guided toward the center of the housing portion 114.

Further, a rib 140 is provided in the accommodating portion 114 so as to protrude from the back side of the umbrella portion 160. This rib 140 is provided arbitrarily and abuts against the head 410 of the clip 400 accommodated inside the main body 110 to prevent the head 410 from rattling in the vertical direction. In particular, since the clip targeted by the main body 110 is a variety of general types of clips, the height of the accommodating portion 114 is such that the head of any clip can be accommodated in the accommodating portion 114. May be set larger. Therefore, depending on the type of clip, there is a possibility that the head may rattle in the vertical direction within the accommodating portion 114, so that the rib 140 prevents rattling. Of course, the height of the rib 140 may be arbitrarily changed according to the head 410 to be accommodated.

The fastener 100 is made of synthetic resin and is integrally molded. And the edge part 161 of the umbrella part 160 shall deform | transform by applying external force, and shall have the elasticity which can be decompress | restored. In addition, the edge 161 has a sucker shape with the back side being thinner toward the tip.

Next, a method of using the fastener 100 will be described in detail with reference to FIGS.

Here, there are various types of attachment parts 200 targeted by the fastener 100 according to the present invention. Generally, as the attachment parts 200, for example, a thin sheet shape such as a nonwoven fabric or a leather sheet is used. Cover materials, hollow structure plates such as plastic corrugated cardboard (having a harmonica cross section), and thick plate-like cover materials such as solid synthetic resin plates and steel plates . Of course, the present invention also includes a plate-like material having a thickness and a surface covering material obtained by attaching or fixing a thin sheet-like material such as the nonwoven fabric, leather sheet, or laminate film on the surface of various laminated plates. It is the attachment component 200 which the fastener 100 which concerns concerns.

The mounting part 200 used in FIGS. 3 and 4 to be described below is a thick plate-like surface covering material such as a hollow structure plate such as a plastic corrugated cardboard. The clip 400 can be elastically deformed so as to be slightly crushed by the head 410 of the clip 400.

First, as shown in FIG. 3, the main body 110 of the fastener 100 is fitted into the opening 210 provided in the attachment component 200. The opening 210 has a circular shape slightly larger than the main body 110 so that the main body 110 can be fitted. Further, even if the opening 210 has a circular shape slightly smaller than the main body 110, the main body 110 may be fitted by elastically deforming the opening 210.

In the state in which the fastener 100 is accommodated in the opening 210, as shown in FIG. 3, the edge portion 161 of the umbrella portion 160 is in contact with the front side of the attachment component 200. Therefore, this edge portion 161 covers the opening 210 and prevents the fastener 100 from being pushed further into the back.

Next, from the state of FIG. 3B, the head 410 of the clip 400 is to be inserted into the insertion opening 120 of the fastener 100 as shown in FIG. However, the insertion opening 120 is blocked by the opening 210 of the attachment part 200, and there is no gap between the opening 210 and the insertion opening 120 for the head 410 to enter. Therefore, as shown in FIG. 4B, a force is applied from the umbrella portion 160 side to push up the fastener 100, and the insertion opening 120 protrudes from the opening 210 to be exposed (hereinafter referred to as "operation 1"). In addition, since the edge part 161 is made of a synthetic resin, it can be easily deformed. Furthermore, since the back side is thinner toward the tip, it is further easily deformed.

Then, in order to further expose the insertion opening 120 and make it easier to insert the head 410, the head 410 is pressed around the opening 210, and as shown in FIG. Is elastically deformed so as to be slightly recessed (hereinafter referred to as “operation 2”).

In this state, when the head 410 of the clip 400 is inserted into the insertion opening 120 and the clip 400 is pushed into the center of the fastener 100, as shown in FIGS. 4B to 4C. The shaft 420 is guided and moved to the bearing hole 113 by the long hole 130, and the one head 410 is moved from the insertion opening 120 to the accommodating portion 114 and accommodated.

Note that when the head 410 is pushed into the insertion opening 120, the portion exposed first so as to jump out from the opening 210 is the inclined surface 151. Therefore, the head 410 is hooked on the inclined surface 151, and then the inclination is inclined. If it pushes along the surface 151 and the long hole 130, the clip 400 can be easily accommodated in the fastener 100. Further, the inclined surface 151 is also a portion that receives the most pressure from the back surface side of the head portion 410 due to the restoring force of the edge portion 161 and the restoring force of the attachment component 200. Therefore, by setting this portion as the inclined surface 151, the pressure can be easily released along the inclination, and the head 410 can be easily moved toward the accommodating portion 114 at the tip of the inclination.

Then, when the attachment of the clip 400 to the fastener 100 is completed, the edge portion 161 and the attachment component 200 are restored to the state shown in FIG. Thereafter, when the main body portion 430 of the clip 400 is fitted into the retaining hole 310 (see FIG. 1) of the attachment portion 300, the attachment component 200 can be fastened to the attachment portion 300 and fixed.

As described above, since the fastener 100 of the present invention is formed of synthetic resin, the edge portion 161 of the fastener 100 is elastically deformed, and as shown in FIG. The head 410 can be inserted into the insertion opening 120 by being exposed from the opening 210. Furthermore, if the attachment component 200 is a hollow structure plate such as a plastic corrugated cardboard, the wall portion itself of the hollow structure plate is thin, so that it can be appropriately recessed against external pressure. Therefore, the head 410 of the clip 400 is pressed against the mounting part 200 and elastically deformed so that the periphery of the opening 210 is recessed as shown in FIG. 4B, and the head 410 is easily inserted into the insertion opening 120. can do.

In the present embodiment shown in FIG. 4, the height of the main body 110 of the fastener 100 is equal to the height in the thickness direction of the attachment part 200, but the present invention is not limited to this. May be different. However, in general, in order to prevent the clip 400 housed inside the fastener 100 from falling off, the insertion opening 120 opened to the side is provided on the inner wall of the opening 210 as shown in FIG. It is desirable to be closed with Therefore, it is desirable that the height of the main body 110 is equal to or lower than the height of the attachment component 200 in the thickness direction.

However, since the insertion opening 120 is blocked by the inner wall of the opening 210, it may be difficult to insert the head 410 into the insertion opening 120. Therefore, an edge 161 that can be elastically deformed is provided so that the insertion opening 120 can be temporarily exposed from the opening 210 and the head 410 can be inserted.

In addition, the edge portion 161 abuts against the surface of the attachment component 200 when the fastener 100 is received in the opening 210 of the attachment component 200, and prevents the fastener 100 from being inserted any more. If so, the edge portion 161 is also a holding member that holds the positional relationship between the fastener 100 and the attachment component 200. Therefore, as shown in FIG. 4, the edge portion 161 is not limited to the flange-like shape of the edge portion of the umbrella portion 160, and the fastener 100 and the attachment component 200 are exposed in order to project the insertion opening 120 out of the opening 210. As long as the holding member can temporarily change the positional relationship, other modes may be used.

In the present embodiment shown in FIG. 4B, the head 410 is easily inserted into the insertion opening 120 by performing both operation 1 and operation 2. However, if the head 410 can be inserted into the insertion opening 120 by only one of the operation 1 and the operation 2, it is not necessary to perform both the operation 1 and the operation 2 as in this embodiment.

Further, the opening 210 of the attachment part 200 for attaching the fastener is not a “dar hole” as in the prior art, and furthermore, since the opening 210 of the attachment part 200 is hidden by the umbrella portion 160 of the fastener 100, When the component 200 is a cover material, it is not necessary to apply a decorative material such as a non-woven fabric or a leather sheet to the opening as in the prior art, so that it does not take time and the appearance of the mounting component 200 is not impaired.

Conventionally, since the head of the clip is directly fitted and held in the opening of the attachment part, it is necessary to adjust the length of the shaft of the clip according to the type and thickness of the attachment part. However, according to the present invention, since the clip is indirectly held by the attachment component 200 via the fastener 100, the clip 400 is attached to the main body of the fastener 100 regardless of the type and thickness of the attachment component 200. It can be accommodated and held in the portion 110, and there is no need to adjust the length of the clip shaft as in the prior art, and a general clip can be used as it is.

In FIG. 4, when the clip 400 is attached, the contact portion 440 is in contact with the fastener 100 and deformed. However, the present invention is not limited to this. For example, when the contact portion 440 having a short length is used or the insertion angle of the head 410 to the insertion opening 120 is changed, the contact portion 440 is deformed. Even if not, the clip 400 can be attached to the fastener 100 without any problem.

Next, another modification of the present invention will be described with reference to FIG. 5 differs from the fastener 100 shown in FIGS. 1 to 4 only in that a bottom insertion opening 121a is provided in a part of the bottom wall 112a of the fastener 100a. Is the same as the fastener 100.

As shown in FIG. 5A, a bottom insertion opening 121a is provided so as to cut out a part of the bottom wall 112a of the fastener 100a adjacent to the long hole 130a. The bottom insertion opening 121a opens upward (perpendicular to the bottom wall 112a) and communicates with the insertion opening 120a as shown in FIG. 5B. The maximum width L5 of the bottom insertion opening 121a is set to be equal to or greater than the maximum width (diameter) of the head 410 of the clip 400. Since the fastener made of synthetic resin has a certain degree of flexibility, the head 410 can be inserted even if the width L5 is the same as or smaller than the maximum width (diameter) of the head 410.

And as shown in FIG.5 (c), the head 410 of the clip 400 is inserted from the bottom part insertion opening 121a opened upwards, and is moved to the insertion opening 120a as it is. On the other hand, the shaft 420 is guided and moved to the bearing hole 113a by the long hole 130a.

Since the head 410 can be inserted from the bottom insertion opening 121a, the edge 161a is elastically deformed to push up the fastener 100a (operation 1), or the head 410 is pressed against the mounting part 200 to be elastically deformed. There is no need to perform (operation 2). However, operation 1 and operation 2 may be appropriately performed depending on the situation.

The fastener of the present invention is not limited to the above-described examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments. Combinations are also included in the scope of their rights.
