【0006】[0006]
以下に、図1乃至図4を参照しながら、本考案の一実施例を説明する。 この実施例の蝶番Aは、図1に示した様に、互いに噛み合あう凹凸縁部を備え た2枚の羽根板1及び2と、両羽根板1,2を相互に回動可能に連結させる連結 ピン3と、連結ピン3の片側端に嵌着させるキャップ状頭部4との、4つの部分 を組合わせた構成を備えている。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In the hinge A of this embodiment, as shown in FIG. 1, two blades 1 and 2 having concave and convex edges that mesh with each other and both blades 1 and 2 are rotatably connected to each other. It is provided with a structure in which four parts, that is, a connecting pin 3 to be connected and a cap-shaped head 4 to be fitted to one end of the connecting pin 3 are combined.
【0007】 図1,4に示した様に、この実施例の一方の羽根板1は、略凸型の金属板から なり、その突出部分aを円筒状に丸め加工して連結ピン3を通す軸受部bを形成 させている。 又、突出部分aの根元箇所には、エンボス部5をプレス手段によって形成させ ている。 この実施例のエンボス部5は、平面視形状が矩形の台形をなしており、その長 手方向の幅は、突出部分aの横幅より幾分狭くしている。As shown in FIGS. 1 and 4, one of the vane plates 1 of this embodiment is made of a substantially convex metal plate, and a protruding portion a thereof is rounded into a cylindrical shape and a connecting pin 3 is passed therethrough. The bearing portion b is formed. Further, an embossed portion 5 is formed by a pressing means at the root of the protruding portion a. The embossed portion 5 of this embodiment has a trapezoidal shape having a rectangular shape in a plan view, and its width in the longitudinal direction is made slightly narrower than the lateral width of the protruding portion a.
【0008】 他方の羽根板2は、略凹形をした金属板からなり、その凹凸縁部の両側の突出 部分a,aを、夫々円筒状に丸め加工して連結ピン3を通す軸受部b,bを形成 させている。cは蝶番の取付用ボルト孔である。The other vane plate 2 is made of a metal plate having a substantially concave shape, and the protruding portions a, a on both sides of the concave and convex edges are each rounded into a cylindrical shape and a bearing portion b through which the connecting pin 3 is inserted. , B are formed. c is a bolt hole for attaching the hinge.
【0009】 連結ピン3は、図2,3に示した様に、その一方端に、抜止用のフランジ付き の頭部3aを一体に設け、他方端には、外周面の二箇所に係合凹部3b,3bを 対向状に設けている。この実施例の係合凹部3bは、切欠溝状をなしている。As shown in FIGS. 2 and 3, the connecting pin 3 is integrally provided at one end thereof with a head portion 3a having a flange for preventing slippage, and at the other end thereof, engaging with two locations on the outer peripheral surface. The recessed portions 3b, 3b are provided so as to face each other. The engagement recess 3b of this embodiment has a notched groove shape.
【0010】 図2,3に示した様に、キャップ状頭部4は、連結ピン3の他方端に嵌着させ 得るキャップ状に形成されており、口縁部外周にはフランジ4aを形成させてい る。 キャップ状頭部4の周壁部分には、上記の嵌着状態で、連結ピン3の係合凹部 3b,3bと対向する夫々の箇所に、この係合凹部3bに嵌合させる係合突部4 a,4aを、キャップ内に向けて突出する様にプレス手段により形成させている 。As shown in FIGS. 2 and 3, the cap-shaped head 4 is formed in a cap shape that can be fitted to the other end of the connecting pin 3, and a flange 4 a is formed on the outer periphery of the rim. ing. On the peripheral wall portion of the cap-shaped head portion 4, in the above-mentioned fitted state, the engaging projections 4 to be fitted into the engaging concave portions 3b at the respective positions facing the engaging concave portions 3b, 3b of the connecting pin 3. The a and 4a are formed by pressing means so as to project toward the inside of the cap.
【0011】 蝶番Aの組立方は、両羽根板1及び2を、各軸受部bが一線上に整列する状態 で噛み合わせたうえ、その一方端から連結ピン3を挿通させる。 そして、連結ピン3の挿通突端に当てがったキャップ状頭部4を、ハンマー等 で打撃すれば、弾性変形性を有するキャップ状頭部4が、図3に示した様に、こ の突端に抜止状態で嵌着されて、組立は迅速・確実に完了する。To assemble the hinge A, both blade plates 1 and 2 are engaged with each other so that the bearing portions b are aligned, and the connecting pin 3 is inserted from one end thereof. Then, when the cap-shaped head 4 applied to the insertion protruding end of the connecting pin 3 is hit with a hammer or the like, the cap-shaped head 4 having elastic deformability becomes, as shown in FIG. The assembly is completed in a quick and reliable manner.
【0012】 組上がった蝶番Aは、連結ピン3の両端が、共に滑らかな略半球形状をなして いる。 その為、アオリ板の取付に用いた場合には、従来の蝶番50の難点である、割 りピン54の尖った脚端が、荷役作業者の皮膚を傷付けたり、衣服に引っ掛かる 等の不都合は完全に解消する。In the assembled hinge A, both ends of the connecting pin 3 have a substantially hemispherical shape that is smooth. Therefore, when it is used for attaching the tilt plate, the disadvantage of the conventional hinge 50 is that the sharp leg end of the split pin 54 may damage the skin of the cargo worker or get caught on clothes. Completely resolved.
【0013】 又、羽根板1及び2が連結ピン3に連結されている各突出部分aの根元箇所に は、アオリ板の開閉の都度、大きな屈撓作用力が及ぼされる。殊に、羽根板1は 、1箇所の突出部分aだけで、連結ピン3に連結されているので、その根元箇所 には強大な集中応力が掛かる。Further, a large bending action force is exerted on the root portion of each protruding portion a where the blade plates 1 and 2 are connected to the connecting pin 3 each time the tilt plate is opened and closed. In particular, since the blade plate 1 is connected to the connecting pin 3 only at one projecting portion a, a strong concentrated stress is applied to the root portion thereof.
【0014】 然し、この根元箇所には、この部分を補強するエンボス部5を設けてあるので 、この様な補強手段を欠く従来のものとは異なって、応力疲労による折損の恐れ も略解消する。However, since the embossed portion 5 that reinforces this portion is provided at this root portion, unlike the conventional one that lacks such reinforcing means, the risk of breakage due to stress fatigue is substantially eliminated. .
【0015】 そして、若し、蝶番Aから連結ピン3を抜取る必要が生じた場合には、ドライ バーの先等を、キャップ状頭部4と羽根板2の側端面との隙間に挿し込んでコジ れば、キャップ状頭部4を外すことが出来る。If it becomes necessary to remove the connecting pin 3 from the hinge A, the tip of the driver or the like is inserted into the gap between the cap-shaped head 4 and the side end surface of the blade plate 2. Then, the cap-shaped head 4 can be removed.
【0016】 尚、上記構成に於いて、細部の構造は適宜に設計変更しても本考案の目的は達 成される。 例えば、エンボス部5の形状は図示に限られず、連結ピン3に対して交叉方向 に任意の間隔を隔てて延びる複数列の突条等であってもよい。In the above structure, the object of the present invention can be achieved even if the design of the detailed structure is changed appropriately. For example, the shape of the embossed portion 5 is not limited to that shown in the figure, and may be a plurality of rows of ridges or the like that extend at arbitrary intervals in the crossing direction with respect to the connecting pin 3.
【0017】[0017]
以上の説明によって明らかな様に、本考案による蝶番は、例えば、トラック荷 台にアオリ板を取付けるのに使えば、従来の、割りピンによって連結ピンを抜止 めしていた従来のものに比べて、以下に列挙した如き実用上の優れた効果を奏す る。 (a) 連結ピンは、その両端共、袋ナット状の滑らかな頭部を備えるので、 従来の蝶番の難点である、割ピンの脚部が衣服や皮膚に引っ掛かる恐れは完全に 解消する。 (b) 又、従来の様に、割りピンが経時的に腐食して、知らぬ間に連結ピン が脱落してしまう恐れも無くなる。 (c) 更に、羽根板の凹凸状縁部の突出部分の根元箇所にエンボス部を設け たことによって、耐応力破断性が顕著に高められて、蝶番の耐久性が大幅に向上 する。 As will be apparent from the above description, the hinge according to the present invention can be used, for example, to attach a tilt plate to a truck bed, as compared with a conventional one in which a connecting pin is prevented by a split pin. It has excellent practical effects as listed below. (A) Since both ends of the connecting pin are provided with smooth cap nut-shaped heads, the difficulty of the conventional hinge, that is, the possibility of the leg part of the split pin being caught on clothes or skin is completely eliminated. (B) Also, unlike the conventional case, there is no possibility that the split pin will corrode over time and the connecting pin will drop off without realizing. (C) Furthermore, by providing the embossed portion at the root of the protruding portion of the uneven edge portion of the blade, the stress rupture resistance is remarkably enhanced, and the durability of the hinge is significantly improved.
