Description
【０００１】[0001]
本考案は、締結部材及び被締結部材の下孔に対して、締結部材の表面方向から 打ち込むことにより、締結部材を被締結部材に締結できるようにした拡張式締結 具に関するものである。 The present invention relates to an expandable fastener that can be fastened to a fastened member by driving the fastening member and the fastened hole of the fastened member from the surface direction of the fastened member.
【０００２】[0002]
この種の拡張式の締結具は、一端に半径外向きの鍔を形成した筒体と、この筒 体に嵌挿するようにした頭部付き軸体とで構成されおり、先行技術としての実公 昭４７−３６７６３号公報には、筒体の他端に、当該筒体の軸方向に延びる筒体 を円周方向に沿って複数本形成し、これら各脚の先端寄り部位に、当該先端寄り 部位の厚さを厚くすることによって半径内向きの凸部を形成して、筒体を締結部 材及び被締結部材の下孔に挿入してから、筒体に軸体を打ち込んで各脚片の凸部 を半径外向きに押圧し、各脚を中心にて半径外向きに広げ変形させることにより 、筒体を抜け不能に保持するようにした考案が記載されている。 This type of expandable fastener is composed of a tubular body with a flange outwardly facing at one end, and a shaft body with a head adapted to be inserted into the tubular body, which is a conventional technique. JP-A-47-36763 discloses that at the other end of the tubular body, a plurality of tubular bodies extending in the axial direction of the tubular body are formed along the circumferential direction, and the tip ends of the respective legs are located near the tip ends. By forming the convex part that is radially inward by increasing the thickness of the side part, insert the cylinder into the fastening member and the prepared hole of the member to be fastened, and then drive the shaft into the cylinder to remove each leg. There is disclosed a device in which the cylindrical body is held so as not to be pulled out by pressing the convex portion of the piece outward in the radial direction and expanding and deforming the legs outward in the radial direction around the center.
【０００３】 また、他の先行技術としての特公昭４６−１７６５６号公報には、筒体の他端 に設けた複数本の脚片の付け根に半径内向きの段部を折り曲げ形成して、各脚片 を筒体の内周面よりも半径内向きに位置させることにより、筒体への軸体の打ち 込みにて各脚片の段部を半径外向きに押圧するようにして、各脚片を半径外向き に開き変形させるようにした考案が記載されている。Further, in Japanese Patent Publication No. 46-17656, which is another prior art, a step portion radially inward is formed by bending a stepped portion at the base of a plurality of leg pieces provided at the other end of the tubular body. By positioning the leg pieces radially inward of the inner peripheral surface of the cylinder, the stepped portion of each leg piece is pressed radially outward by driving the shaft body into the cylinder, so that each leg A device is described in which the piece is opened and deformed radially outward.
【０００４】[0004]
しかし、前者のように、筒体における各脚の厚さを変えることによって当該脚 に段部を形成する手段では、開き変形した脚が元の状態に戻り変形することを段 部にて確実に防止できるので、締結強度を向上できると言う利点を有するが、そ の反面、筒体を金属製にする場合には、厚肉状の金属パイプや丸棒を切削加工し て製造しなくてはならないため、筒体の製造コストが嵩むと言う問題があった。 However, as in the former case, the step of forming the stepped portion on the leg by changing the thickness of each leg in the tubular body ensures that the leg that has undergone the open deformation returns to its original state and deforms at the stepped portion. This has the advantage that the fastening strength can be improved, but on the other hand, if the cylinder is made of metal, it must be manufactured by cutting a thick metal pipe or round bar. Therefore, there is a problem that the manufacturing cost of the cylinder increases.
【０００５】 他方、後者の場合には、筒体は、金属パイプを板金加工することによって形成 することができるので、筒体の製造コストを低減できると言う利点を有するが、 その反面、筒体における脚片は平板状であって容易に変形し易いため、軸体にて 脚片の段部を押圧するに際して、当該段部が平らに潰れ変形してしまって脚片を 充分に開き変形させることができず、締結強度が低いと言う問題があった。On the other hand, in the latter case, since the tubular body can be formed by sheet metal working of a metal pipe, it has an advantage that the manufacturing cost of the tubular body can be reduced. Since the leg piece in is flat and easily deformed, when the shaft body presses the stepped portion of the leg piece, the stepped portion is flattened and deformed, and the leg piece is sufficiently opened and deformed. However, there was a problem that the fastening strength was low.
【０００６】 本考案は、筒体の加工の容易性を損なうことなく、締結強度を向上した締結具 を提供することを目的とするものである。An object of the present invention is to provide a fastener having improved fastening strength without impairing the ease of processing the tubular body.
【０００７】[0007]
この目的を達成するため本考案は、金属板を折り曲げて形成した筒体と、該筒 体内にその一端方向から打ち込むようにした頭部付き軸体とを備え、前記筒体の 一端に、半径外向きの鍔片を連接する一方、筒体の他端に、当該筒体の軸方向に 延びる脚片を円周方向に沿って複数本連接し、前記各脚片を、前記筒体の軸線方 向視で半径内向き凸状に折り曲げ形成することにて、これら各脚片に対する内接 円の直径を前記軸体の外径よりも小径に形成する構成にした。 In order to achieve this object, the present invention comprises a cylindrical body formed by bending a metal plate, and a shaft body with a head adapted to be driven into the cylindrical body from one end thereof, and a radius is provided at one end of the cylindrical body. While connecting the outward flange pieces, a plurality of leg pieces extending in the axial direction of the cylinder body are connected to the other end of the cylinder body along the circumferential direction, and each of the leg pieces is connected to the axis line of the cylinder body. By bending inwardly in a convex shape in a radial direction, the diameter of the inscribed circle for each leg is formed to be smaller than the outer diameter of the shaft body.
【０００８】[0008]
この構成に係る締結具による締結作業は従来と同様であり、締結部材及び被締 結部材に予め下孔を穿設しておき、その下孔に、筒体を、脚片を先にした状態で 締結部材の表面側から挿入し、次いで、軸体を、その頭部が筒体の鍔に接当する までハンマー等にて筒体内に打ち込むことによって行われる。 The fastening work with the fastener according to this configuration is the same as the conventional one, and a lower hole is formed in advance in the fastening member and the member to be fastened, and the lower body is provided with the cylinder and the leg first. Then, the fastening member is inserted from the front surface side, and then the shaft body is driven into the cylinder body by a hammer or the like until its head contacts the flange of the cylinder body.
【０００９】 すると、筒体における各脚片に対する内接円の直径が軸体の外径よりも小径で あることにより、筒体への軸体の打ち込みにて各脚片が半径外向きに押圧されて 、各脚片が、当該各脚片間の間隔が先端に行くに従って拡大するように広がり変 形し、筒体が締結部材及び被締結部材から抜け不能に保持されるため、締結部材 は被締結部材に対して締結される。Then, since the diameter of the inscribed circle for each leg piece in the tubular body is smaller than the outer diameter of the shaft body, each leg piece is pressed radially outward by driving the shaft body into the tubular body. Then, each leg piece is expanded and deformed so that the interval between the leg pieces expands toward the tip, and the tubular body is held so as not to come off from the fastening member and the fastened member. It is fastened to the fastened member.
【００１０】 この場合、各脚片が筒体の軸線方向視で半径内向きに凸状の断面形状であるこ とにより、リブ効果によってそれら各脚片の剛性が格段に向上するから、軸体の 打ち込みにより各脚片に作用する半径外向きの押圧力が各脚片の付け根部に集中 的に作用することになって、各脚片を、その付け根部を中心にして半径外向きに 広がるように確実に変形させることができ、その結果、筒体の抜けを確実に防止 して締結強度を向上できることになる。In this case, since the leg pieces have a cross-sectional shape that is convex inward in the radial direction when viewed in the axial direction of the tubular body, the rigidity of each leg piece is significantly improved by the rib effect. The radial outward pressing force acting on each leg by the driving is concentrated on the base of each leg, so that each leg spreads radially outward around the base. As a result, the tubular body can be reliably prevented from coming off and the fastening strength can be improved.
【００１１】 また、筒体は、帯状の金属板をプレス装置にて板金加工することによって量産 することができるから、低コストで製造することができる。 従って本考案によると、筒体と軸体とから成る拡張式の締結具において、製造 コストをアップすることなく、締結強度を向上できる効果を有する。Further, since the cylindrical body can be mass-produced by processing a band-shaped metal plate by sheet metal working with a pressing device, it can be manufactured at low cost. Therefore, according to the present invention, in the expandable fastener including the tubular body and the shaft, the fastening strength can be improved without increasing the manufacturing cost.
【００１２】[0012]
次に、本考案の実施例を図面に基づいて説明する。 図１〜図５に示すのは第１の実施例であり、これらの図において符号１は締結 具を示し、該締結具１は、鋼板等の金属板を折り曲げて形成した筒体２と、中実 状の金属製軸体３とから成り、軸体３の一端には大径の頭部４を形成している。 Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 5 show a first embodiment. In these drawings, reference numeral 1 denotes a fastener, and the fastener 1 is a tubular body 2 formed by bending a metal plate such as a steel plate, It is composed of a solid metal shaft body 3, and a large-diameter head 4 is formed at one end of the shaft body 3.
【００１３】 前記筒体２の一端に、半径外向きに突出した複数枚の鍔片５を一体的に連接し 、筒体１の他端に、当該筒体１の軸方向に延びる脚片６を、円周方向に沿って複 数枚（実施例では４枚）一体的に連接し、各脚片６を、筒体２の軸線方向視にお いて半径内向きに凸状となるよう断面く字状に屈曲して、各脚片６の頂点６ａを 筒体２の内周面よりも半径内側に位置させることにより、各脚片６に対する内接 円Ｍの直径ｄ１が筒体２の内径ｄ２及び軸体３の外径Ｄ１よりも小径となるよう に形成する。A plurality of flange pieces 5 projecting radially outward are integrally connected to one end of the cylinder body 2, and a leg piece 6 extending in the axial direction of the cylinder body 1 is connected to the other end of the cylinder body 1. A plurality of pieces (four pieces in the embodiment) are integrally connected along the circumferential direction, and each leg piece 6 has a cross-section that is convex inward in the radial direction when viewed in the axial direction of the tubular body 2. By bending the leg 6 in a dogleg shape and arranging the apex 6a of each leg 6 inside the inner peripheral surface of the tubular body 2, the diameter d1 of the inscribed circle M with respect to each leg 6 is equal to that of the tubular body 2. The diameter is smaller than the inner diameter d2 and the outer diameter D1 of the shaft body 3.
【００１４】 この場合、各脚片６は、図２に明示するように、その頂点６ａと筒体２の軸芯 Ｏとを結ぶ線Ｓを挟んだ両側の部位が、筒体２の軸線方向視において非対称形と なるように、換言すると、頂点６ａを挟んだ左右両側の部位の幅寸法Ｌ１，Ｌ２ が互いに異なるように形成しており、また、各脚片６を、先端に行くに従って筒 体２の軸心Ｏに徐々に近づくよう筒体２の軸線に対して適宜の角度θで傾斜させ ることにより、各脚片６全体が先窄まりのテーパ状となるようにしている。In this case, as shown in FIG. 2, in each leg piece 6, the portions on both sides of the line S connecting the apex 6 a and the axis O of the cylinder 2 are in the axial direction of the cylinder 2. In other words, the width dimensions L1 and L2 of the left and right sides sandwiching the apex 6a are formed to be different from each other so as to be asymmetrical in the visual sense. By tilting the leg 2 at an appropriate angle θ with respect to the axis of the cylindrical body 2 so as to gradually approach the axis O of the body 2, the entire leg pieces 6 are tapered in a tapered shape.
【００１５】 なお、各脚片６の全体が先窄まりのテーパ状であるため、各脚片６に対する内 接円７の直径ｄ１は先端方向に向けて縮小するが、何れの部位の直径ｄ１も筒体 ２の内径ｄ２及び軸体３の外径Ｄ１よりも小径である。 前記筒体２には、その軸心を挟んだ対称の部位に一対の突起８を形成している 。Since each leg 6 has a tapered shape as a whole, the diameter d1 of the inscribed circle 7 with respect to each leg 6 decreases toward the distal end. Is smaller than the inner diameter d2 of the cylindrical body 2 and the outer diameter D1 of the shaft body 3. A pair of protrusions 8 are formed on the cylindrical body 2 at symmetrical portions with the axis center therebetween.
【００１６】 他方、前記軸体３は、その外径Ｄ１が前記筒体２の内径ｄ２よりも若干大径に なるようにしており、該軸体３の先端に、先窄まりのテーパ部３ａを介して小径 部３ｂを一体的に形成し、テーパ部３ａを筒体２の一端縁に接当した状態で、小 径部３ｂの先端が各脚片６にて弾性的に挟持され、軸体３を筒体２に対して脱落 不能に仮装着できるようにしている。On the other hand, the shaft body 3 has an outer diameter D1 slightly larger than the inner diameter d2 of the cylindrical body 2, and a tapered portion 3a with a tapered end is formed at the tip of the shaft body 3. The small diameter portion 3b is integrally formed with the tapered portion 3a in contact with the one end edge of the tubular body 2, and the tip end of the small diameter portion 3b is elastically clamped by each leg piece 6, The body 3 can be temporarily attached to the cylindrical body 2 so as not to fall off.
【００１７】 符号９は座金を示す。 以上の構成において、締結部材Ａを被締結部材Ｂに締結するには、締結部材Ａ と被締結部材Ｂとに予め下孔ａ，ｂを穿設しておき、この下孔ａ，ｂに筒体２を 挿入して、筒体２に向けて軸体３をハンマー等にて打ち込めば良い。 すると、筒体２における各脚片６に対する内接円Ｍの直径ｄ１が軸体３の外径 Ｄ１よりも小径であることにより、筒体２への軸体３の打ち込みにて各脚片６は 半径外向きに押圧されるため、各脚片６が、当該各脚片６間の間隔が先端に行く に従って拡大するように広がり変形して、筒体２が抜け不能に保持され、その結 果、被締結部材Ｂに対して締結部材Ａが締結される。Reference numeral 9 indicates a washer. In the above configuration, in order to fasten the fastening member A to the fastened member B, the fastening members A and the fastened member B are preliminarily provided with the lower holes a and b, and the lower holes a and b are provided with the cylinders. It suffices to insert the body 2 and drive the shaft body 3 toward the cylindrical body 2 with a hammer or the like. Then, since the diameter d1 of the inscribed circle M with respect to each leg piece 6 in the tubular body 2 is smaller than the outer diameter D1 of the shaft body 3, each leg piece 6 is driven by driving the shaft body 3 into the tubular body 2. Is pressed radially outward, the leg pieces 6 are expanded and deformed so that the distance between the leg pieces 6 increases as the distance between the leg pieces 6 increases, and the tubular body 2 is held so as not to be pulled out. As a result, the fastening member A is fastened to the fastened member B.
【００１８】 この場合、各脚片６が、筒体２の軸線方向視において半径内側に向かって凸状 の断面形状であることにより、リブ効果によってそれら各脚片６の剛性が格段に 向上するから、軸体３の打ち込みにて各脚片６に作用する半径外向きの押圧力は 、各脚片６の付け根部６ｂに集中的に作用することになって、各脚片６を、その 付け根部６ｂを中心にして確実に広げ変形させることができて締結強度を向上で きるのであり、また、筒体２は、帯状の金属板をプレス加工することによって量 産することができるから、低コストで製造することができるのである。In this case, since each leg 6 has a cross-sectional shape that is convex inward in the radial direction when viewed in the axial direction of the tubular body 2, the rigidity of each leg 6 is significantly improved by the rib effect. Therefore, the radial outward pressing force that acts on each leg piece 6 by driving the shaft body 3 concentrates on the base portion 6b of each leg piece 6, and each leg piece 6 is Since it can be surely expanded and deformed around the root portion 6b to improve the fastening strength, and the tubular body 2 can be mass-produced by pressing a band-shaped metal plate. It can be manufactured at low cost.
【００１９】 上記の実施例のように筒体２に突起８を形成しておくと、筒体２への軸体３の 打ち込みに際して、突起８を潰し変形させつつ筒体２を広げ変形させることにな り、突起８の弾性力にて、筒体２を軸体３の外周面と被締結部材Ｂの下孔ｂとの 間に突っ張らせた状態にすることができるので、軸体３の抜け防止機能を向上す ることができる（突起８は１個のみ又は３個以上設けても良い）。When the projection 8 is formed on the cylindrical body 2 as in the above-described embodiment, when the shaft body 3 is driven into the cylindrical body 2, the projection 8 is crushed and deformed while the cylindrical body 2 is expanded and deformed. Therefore, the elastic force of the protrusion 8 can make the cylindrical body 2 stretched between the outer peripheral surface of the shaft body 3 and the prepared hole b of the member to be fastened B, so that the shaft body 3 The removal prevention function can be improved (only one protrusion 8 or three or more protrusions 8 may be provided).
【００２０】 なお、図５に一点鎖線で示すように、軸体３の外周に環状溝１０を刻設する一 方、筒体２に、前記環状溝１０に係合する適宜本数の爪片１１を、筒体２の先端 方向に向けて斜め内向きに延びるように切り起こし形成しても良く、このように 形成すると、軸体３の抜けを確実に防止できる。 上記の実施例は、筒体２の脚片６を断面く字状に形成した場合であったが、図 ６に第２の実施例として示すように、脚片６を円弧状の断面形状に形成しても良 いのであり、また、脚片６の本数は４本に限らないことは言うまでもない。As shown by the alternate long and short dash line in FIG. 5, an annular groove 10 is formed on the outer periphery of the shaft body 3, while an appropriate number of claw pieces 11 that engage with the annular groove 10 are formed on the cylindrical body 2. May be formed by cutting and raising so as to extend obliquely inward toward the tip end direction of the tubular body 2. By forming in this way, the shaft body 3 can be reliably prevented from coming off. In the above-mentioned embodiment, the leg piece 6 of the tubular body 2 is formed in a V-shaped cross section. However, as shown as a second embodiment in FIG. 6, the leg piece 6 is formed in an arcuate cross-sectional shape. Needless to say, the leg pieces 6 may be formed, and the number of leg pieces 6 is not limited to four.
【００２１】 また、第３の実施例として図７（Ａ）に示すように、脚片６の付け根部６ｂに 溝１２を切り欠き形成するとか、図７（Ｂ）に示すように、各脚片６の付け根部 ６ｂに孔１３を穿設するとかして、各脚片６の付け根部６ｂの強度を低下させる ことにより、当該各脚片６の付け根部６ｂが曲がり変形し易いように形成しても 良い。Further, as a third embodiment, as shown in FIG. 7 (A), a groove 12 is cut out in the base portion 6b of the leg piece 6, or each leg is formed as shown in FIG. 7 (B). By forming a hole 13 in the root portion 6b of the piece 6 to reduce the strength of the root portion 6b of each leg piece 6, the root portion 6b of each leg piece 6 is formed so as to be easily bent and deformed. It's good.
【００２２】 更に、筒体２の鍔片５は実施例のように放射状に形成することには限らず、筒 体２の全周にわたってリング状に延びるように形成しても良いことは言うまでも ない。 更にまた、軸体３には必ずしもテーパ部３ａ及び小径部３ｂを設ける必要はな いが、実施例のように小径部３ｂを設けて軸体３を筒体２に仮装着できるように しておくと、締結作業に際して一々筒体２に軸体３を挿入する手間を省けるので 、作業能率を向上できる利点がある。Further, it is needless to say that the collar piece 5 of the cylindrical body 2 is not limited to be formed radially like the embodiment, and may be formed so as to extend in a ring shape over the entire circumference of the cylindrical body 2. Nor. Furthermore, the shaft body 3 does not necessarily have to be provided with the tapered portion 3a and the small diameter portion 3b, but as in the embodiment, the small diameter portion 3b is provided so that the shaft body 3 can be temporarily attached to the cylindrical body 2. By doing so, it is possible to save the labor of inserting the shaft body 3 into the cylindrical body 2 one by one during the fastening work, which is advantageous in that the working efficiency can be improved.
