Description

本開示は母材に係止対象物を係止するためのクリップに関する。 The present disclosure relates to a clip for locking an object to be locked to a base material.

アクスルケース等にクリップを設け、そのクリップで管又はケーブル等の係止対象物を係止してアクスルケース等に配管又は配索する場合がある。 A clip may be provided on the axle case or the like, and a locking object such as a pipe or a cable may be locked by the clip to pipe or route the pipe or the cable to the axle case or the like.

図１２に示すように、クリップ２０は、両側にアーム板部２１を有し、これらアーム板部２１を係止対象物５に巻き付かせることで係止対象物５を係止する。 As shown in FIG. 12, the clip 20 has arm plate portions 21 on both sides, and the locking object 5 is locked by winding these arm plate portions 21 around the locking object 5.

かかるクリップ２０は、プレス加工にて容易かつ安価に製造できる。このため、アンチブレーキシステム等のコンピュータ制御が一般的となり、配管及び配索が増えた近年の車両においては特に有用である。 Such a clip 20 can be easily and inexpensively manufactured by press working. For this reason, computer control such as an anti-brake system has become common, and it is particularly useful in recent vehicles in which piping and wiring have increased.

しかしながら、上述のクリップ２０は、アーム板部２１の基端（以下、屈曲部２２）を中心としてアーム板部２１を開閉させるものであるため、アーム板部２１を繰り返し開閉させると屈曲部２２が破断する虞がある。具体的には、クリップ２０に係止対象物５を係止させる場合、図１３に示すようにアーム板部２１を開いたのち、クリップ２０に係止対象物５を投入し、アーム板部２１を閉じると共に係止対象物５に沿わせるように屈曲させる。そして、交換、修理、メンテナンス等の目的でクリップ２０から係止対象物５を取り外す場合、アーム板部２１を再度開閉する。このようにアーム板部２１を繰り返し開閉した場合、図１４に示すように屈曲部２２が破断する虞がある。屈曲部２２が破断した場合、代わりとなるクリップをアクスルケース等に溶接等にて取り付けなければならない。 However, since the clip 20 described above opens and closes the arm plate 21 around the base end (hereinafter, bent portion 22) of the arm plate 21, when the arm plate 21 is repeatedly opened and closed, the bent portion 22 opens and closes. There is a risk of breakage. Specifically, when locking the locking object 5 on the clip 20, after opening the arm plate 21 as shown in FIG. 13, the locking object 5 is thrown into the clip 20 and the arm plate 21 is inserted. Is closed and bent so as to be along the locking object 5. Then, when the locking object 5 is removed from the clip 20 for the purpose of replacement, repair, maintenance, or the like, the arm plate portion 21 is opened and closed again. When the arm plate portion 21 is repeatedly opened and closed in this way, the bent portion 22 may break as shown in FIG. When the bent portion 22 is broken, a substitute clip must be attached to the axle case or the like by welding or the like.

そこで本開示は、かかる事情に鑑みて創案され、その目的は、アーム板部の開閉による屈曲部の破断を抑制することができるクリップを提供することにある。 Therefore, the present disclosure was conceived in view of such circumstances, and an object of the present disclosure is to provide a clip capable of suppressing breakage of a bent portion due to opening and closing of an arm plate portion.

以下、添付図面を参照して本開示の実施形態を説明する。なお、後述する実施の形態においては、説明の便宜上、アーム板部の延長方向を上方とし、アーム板部の屈曲方向を側方（左右方向）とする。 Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In the embodiment described later, for convenience of explanation, the extension direction of the arm plate portion is upward, and the bending direction of the arm plate portion is lateral (left-right direction).

図１は、本開示の一実施形態に係るクリップ１を斜め上方から視た斜視図である。図２は、図１記載のクリップ１をＡ−Ａ線から矢印方向に視た矢視図（背面図）である。 FIG. 1 is a perspective view of the clip 1 according to the embodiment of the present disclosure as viewed from diagonally above. FIG. 2 is an arrow view (rear view) of the clip 1 shown in FIG. 1 viewed in the direction of the arrow from the line AA.

図１及び図２に示すように、クリップ１は、板金をプレス加工して形成される。クリップ１は、軟鉄、鋼鉄、アルミニウム等の繰り返し屈曲可能な金属で構成される。クリップ１は、アクスルケース、フレーム、キャビン等の母材２に固定されるベース板部３と、ベース板部３に一体に形成されると共に母材２から離間する方向に略直角に屈曲して形成される左右一対のアーム板部４とを備える。なお、アーム板部４は一対に限るものではない。アーム板部４は単数であってもよく、３つ以上の複数であってもよい。 As shown in FIGS. 1 and 2, the clip 1 is formed by pressing a sheet metal. The clip 1 is made of a repeatedly bendable metal such as soft iron, steel, and aluminum. The clip 1 is integrally formed with the base plate portion 3 fixed to the base material 2 such as an axle case, a frame, and a cabin, and is bent at a substantially right angle in a direction away from the base material 2. It includes a pair of left and right arm plate portions 4 to be formed. The arm plate portions 4 are not limited to a pair. The arm plate portion 4 may be singular or may be three or more.

ベース板部３は、前後に長い板状に形成される。また、ベース板部３の幅寸法Ｗは、係止対象物５たる管又はケーブルの直径φと略同じに設定される。ベース板部３は、長手方向（前後方向）の両端を母材２に溶接される。なお、ベース板部３は、母材２にボルト、リベット等で締結されてもよい。 The base plate portion 3 is formed in a long plate shape in the front-rear direction. Further, the width dimension W of the base plate portion 3 is set to be substantially the same as the diameter φ of the pipe or cable which is the locking object 5. Both ends of the base plate portion 3 in the longitudinal direction (front-rear direction) are welded to the base material 2. The base plate portion 3 may be fastened to the base material 2 with bolts, rivets, or the like.

アーム板部４は、ベース板部３に沿って配置される係止対象物５に巻き付かせるためのものである。アーム板部４は、ベース板部３の両側に上方に延びて形成される。また、ベース板部３の右側に形成されるアーム板部４と、左側に形成されるアーム板部４とは、互いに前後方向に位置をずらして形成される。これにより、係止対象物５にアーム板部４を巻き付かせたとき、左右のアーム板部４が互いに干渉するのを防ぐことができる。 The arm plate portion 4 is for winding around a locking object 5 arranged along the base plate portion 3. The arm plate portion 4 is formed so as to extend upward on both sides of the base plate portion 3. Further, the arm plate portion 4 formed on the right side of the base plate portion 3 and the arm plate portion 4 formed on the left side are formed so as to be displaced from each other in the front-rear direction. As a result, when the arm plate portion 4 is wound around the locking object 5, it is possible to prevent the left and right arm plate portions 4 from interfering with each other.

また、アーム板部４の長手方向（上下方向）の中間部には、ベース板部３及びアーム板部４間の屈曲部６より低強度の低強度部７が形成される。低強度部７は、アーム板部４の長手方向に一定の長さに亘って形成される。ここでいう強度とは、板厚方向の力に対する曲がり難さである。すなわち、低強度とは板厚方向の力に対して曲がり易いことを意味し、高強度とは板厚方向に曲がり難いことを意味する。また、一定の長さとは、係止対象物５の形状及び外周寸法等に応じて予め設定される長さであり、係止対象物５が断面円形である場合、周長の１／８から１／４程度の長さに設定される。なお、低強度部７の長さはこれに限るものではない。低強度部７の最適な長さは、材料の靱性等によっても変わる。 Further, a low-strength portion 7 having a lower strength than the bent portion 6 between the base plate portion 3 and the arm plate portion 4 is formed in the intermediate portion in the longitudinal direction (vertical direction) of the arm plate portion 4. The low-strength portion 7 is formed over a certain length in the longitudinal direction of the arm plate portion 4. The strength referred to here is the difficulty of bending with respect to a force in the plate thickness direction. That is, low strength means that it is easy to bend with respect to a force in the plate thickness direction, and high strength means that it is difficult to bend in the plate thickness direction. The constant length is a length preset according to the shape and outer peripheral dimensions of the locking object 5, and when the locking object 5 has a circular cross section, the length is from 1/8 of the peripheral length. The length is set to about 1/4. The length of the low-strength portion 7 is not limited to this. The optimum length of the low-strength portion 7 also depends on the toughness of the material and the like.

低強度部７は、アーム板部４の前後方向の寸法Ｌ２を屈曲部６の前後方向の寸法Ｌ１より小さく（幅狭に）することで形成される。具体的には、アーム板部４の前後方向の両縁は、前後対称の波形に形成される。低強度部７は、アーム板部４の前後方向にくびれる位置に形成される。低強度部７は、係止対象物５にアーム板部４を巻き付けたとき、係止対象物５の側面（左右方向に向く面）に当接する位置に形成される。 The low-strength portion 7 is formed by making the dimension L2 in the front-rear direction of the arm plate portion 4 smaller (narrower) than the dimension L1 in the front-rear direction of the bent portion 6. Specifically, both edges of the arm plate portion 4 in the front-rear direction are formed in a front-rear symmetrical waveform. The low-strength portion 7 is formed at a position constricted in the front-rear direction of the arm plate portion 4. The low-strength portion 7 is formed at a position where it comes into contact with the side surface (the surface facing in the left-right direction) of the locking object 5 when the arm plate portion 4 is wound around the locking object 5.

また、低強度部７より先端側のアーム板部４には、低強度部７より高強度の中強度部８が低強度部７に隣接して形成される。中強度部８は、前後方向の寸法Ｌ３を低強度部７の前後方向の寸法Ｌ２より大きく（幅広に）形成され、屈曲部６の前後方向の寸法Ｌ１より小さく（幅狭に）形成される（Ｌ１＞Ｌ３＞Ｌ２）。このため、係止対象物５にアーム板部４を巻き付かせるとき、中強度部８は低強度部７を先に屈曲させるように作用する。これにより、アーム板部４が先端側から屈曲して弛むことを防止または抑制できる。そして、低強度部７が屈曲された後には、係止対象物５に沿う低強度部７を支点として中強度部８を屈曲させることができ、屈曲部６に過大な力が作用することを防止または抑制できる。中強度部８は、係止対象物５にアーム板部４を巻き付けたとき、係止対象物５の上面（ベース板部３とは反対側の面）に当接する位置に形成される。 Further, on the arm plate portion 4 on the tip side of the low-strength portion 7, a medium-strength portion 8 having a higher strength than the low-strength portion 7 is formed adjacent to the low-strength portion 7. The medium-strength portion 8 is formed so that the dimension L3 in the front-rear direction is larger (wider) than the dimension L2 in the front-rear direction of the low-strength portion 7 and smaller (narrower) than the dimension L1 in the front-rear direction of the bent portion 6. (L1> L3> L2). Therefore, when the arm plate portion 4 is wound around the locking object 5, the medium-strength portion 8 acts to bend the low-strength portion 7 first. As a result, it is possible to prevent or suppress the arm plate portion 4 from bending from the tip end side and loosening. Then, after the low-strength portion 7 is bent, the medium-strength portion 8 can be bent with the low-strength portion 7 along the locking object 5 as a fulcrum, and an excessive force acts on the bent portion 6. Can be prevented or suppressed. The medium-strength portion 8 is formed at a position where it comes into contact with the upper surface of the locking object 5 (the surface opposite to the base plate 3) when the arm plate 4 is wound around the locking object 5.

また、中強度部８より先端側のアーム板部４には、アーム板部４を開閉するときに把持するための把持部９が形成される。把持部９は、前後方向の寸法を中強度部８より小さく形成される。これにより、中強度部８を把持する工具等が隣接するアーム板部４に干渉することを防止または抑制できる。 Further, the arm plate portion 4 on the tip side of the medium strength portion 8 is formed with a grip portion 9 for gripping when opening and closing the arm plate portion 4. The grip portion 9 is formed to have a dimension in the front-rear direction smaller than that of the medium-strength portion 8. As a result, it is possible to prevent or suppress the tool or the like that grips the medium-strength portion 8 from interfering with the adjacent arm plate portion 4.

なお、アーム板部４が十分柔軟である場合、中強度部８は省略されてもよい。 If the arm plate portion 4 is sufficiently flexible, the medium strength portion 8 may be omitted.

次に本実施の形態の作用について述べる。 Next, the operation of this embodiment will be described.

図３及び図４に示すように、クリップ１に係止対象物５を係止させる場合、それぞれのアーム板部４に屈曲部６の屈曲方向とは反対方向に屈曲させる力を作用させてアーム板部４を開く。このとき、低強度部７は屈曲部６より低強度に形成されるため、屈曲部６より先に低強度部７が屈曲される。これにより、前記屈曲させる力は低強度部７に吸収され、屈曲部６が変形されることが防止または抑制される。そして、低強度部７は、長手方向に一定の長さに亘って形成されるため、比較的大きな半径の弧状に屈曲される。 As shown in FIGS. 3 and 4, when the locking object 5 is locked to the clip 1, the arm is subjected to a force for bending each arm plate portion 4 in the direction opposite to the bending direction of the bending portion 6. Open the plate part 4. At this time, since the low-strength portion 7 is formed to have a lower strength than the bent portion 6, the low-strength portion 7 is bent before the bent portion 6. As a result, the bending force is absorbed by the low-strength portion 7, and the bending portion 6 is prevented or suppressed from being deformed. Since the low-strength portion 7 is formed over a certain length in the longitudinal direction, the low-strength portion 7 is bent in an arc shape having a relatively large radius.

この後、ベース板部３上に係止対象物５を、ベース板部３の長手方向に沿って配置する。このとき、屈曲部６は略直角に屈曲された形状を保っており、低強度部７より基端側のアーム板部４は起立されている。係止対象物５はアーム板部４に両側を当接されて緩く保持される。このため、係止対象物５の位置決めが容易になり、作業性が向上する。 After that, the locking object 5 is arranged on the base plate portion 3 along the longitudinal direction of the base plate portion 3. At this time, the bent portion 6 maintains a shape of being bent at a substantially right angle, and the arm plate portion 4 on the proximal end side of the low-strength portion 7 is erected. The locking object 5 is brought into contact with the arm plate portion 4 on both sides and is loosely held. Therefore, the positioning of the locking object 5 becomes easy, and the workability is improved.

この後、図５及び図６に示すように、それぞれのアーム板部４を係止対象物５側に屈曲させて係止対象物５に巻き付ける。このとき、アーム板部４は、屈曲部６より低強度に形成されるため、アーム板部４を屈曲させる力は低強度部７を屈曲させることで吸収される。よって、屈曲部６が変形することは防止または抑制される。また、低強度部７は、アーム板部４を開いたときとは反対方向に屈曲されることとなる。しかし、低強度部７は、アーム板部４を開いたときに比較的大きな半径の弧状に屈曲される。このため、低強度部７に局所的に大きな応力が残っていることはなく、低強度部７が破断することは防止される。 After that, as shown in FIGS. 5 and 6, each arm plate portion 4 is bent toward the locking object 5 and wound around the locking object 5. At this time, since the arm plate portion 4 is formed to have a lower strength than the bending portion 6, the force for bending the arm plate portion 4 is absorbed by bending the low strength portion 7. Therefore, deformation of the bent portion 6 is prevented or suppressed. Further, the low-strength portion 7 is bent in the direction opposite to that when the arm plate portion 4 is opened. However, the low-strength portion 7 is bent in an arc shape having a relatively large radius when the arm plate portion 4 is opened. Therefore, no large stress remains locally in the low-strength portion 7, and the low-strength portion 7 is prevented from breaking.

また、クリップ１から係止対象物５を一旦取り外して再度係止させる場合、アーム板部４を再度開閉させる必要があるが、上述したようにアーム板部４を開閉しても屈曲部６が変形することはなく、屈曲部６が破断することは防止される。また、低強度部７は、アーム板部４の開閉に伴って屈曲されるが、長手方向に一定の長さに設定されるため、局所的に大きな応力が残ることはない。このため、低強度部７が破断することは防止される。そして、クリップ１が数次曲げに強くなることにより、製造ラインや市場での係止対象物交換時の破断リスクを解消または低減でき、クリップ１が破断したときのクリップ溶接作業の発生を防止または抑制できる。 Further, when the locking object 5 is once removed from the clip 1 and locked again, it is necessary to open and close the arm plate portion 4 again, but as described above, even if the arm plate portion 4 is opened and closed, the bent portion 6 remains. It does not deform, and the bent portion 6 is prevented from breaking. Further, the low-strength portion 7 is bent as the arm plate portion 4 is opened and closed, but since it is set to a constant length in the longitudinal direction, a large stress does not remain locally. Therefore, the low-strength portion 7 is prevented from breaking. By making the clip 1 resistant to multiple bending, the risk of breakage at the time of exchanging the locked object in the production line or the market can be eliminated or reduced, and the occurrence of clip welding work when the clip 1 breaks can be prevented. Can be suppressed.

以上、本開示の実施形態を詳細に述べたが、本開示は以下のような他の実施形態も可能である。 Although the embodiments of the present disclosure have been described in detail above, the present disclosure may also include the following other embodiments.

（１）図７に示すように、低強度部７は、断面波形に形成されることで構成されてもよい。 (1) As shown in FIG. 7, the low-strength portion 7 may be formed by being formed into a cross-sectional waveform.

（２）図８及び図９に示すように、低強度部７には、板厚方向に突起する凹凸１０が形成されることで構成されてもよい。この場合、凹凸１０は前後方向に長く形成されるとよい。また、凹凸１０は、アーム板部４の長手方向に複数形成されるとよい。またさらに、凹凸１０は、エンボス加工等によって形成されるとよい。複数の凹凸１０を一括して効率よく形成できる。また、凹凸１０の板厚を周囲の板厚より薄く形成することができ、低強度部７の強度を容易に低下させることができる。 (2) As shown in FIGS. 8 and 9, the low-strength portion 7 may be formed by forming unevenness 10 protruding in the plate thickness direction. In this case, the unevenness 10 may be formed long in the front-rear direction. Further, it is preferable that a plurality of irregularities 10 are formed in the longitudinal direction of the arm plate portion 4. Further, the unevenness 10 may be formed by embossing or the like. A plurality of irregularities 10 can be efficiently formed at once. Further, the plate thickness of the unevenness 10 can be formed thinner than the surrounding plate thickness, and the strength of the low-strength portion 7 can be easily reduced.

（３）図８及び図９に示すように、屈曲部６には、内周側に突起する補強部１１が設けられてもよい。この場合、補強部１１は、屈曲部６の外周面に左右方向に延びる溝形の凹部１２を形成して構成されるとよい。凹部１２は、ベース板部３に対して斜め上方に延びるとよく、屈曲部６の内周面より内側に位置されるとよい。 (3) As shown in FIGS. 8 and 9, the bent portion 6 may be provided with a reinforcing portion 11 projecting on the inner peripheral side. In this case, the reinforcing portion 11 may be formed by forming a groove-shaped recess 12 extending in the left-right direction on the outer peripheral surface of the bent portion 6. The recess 12 may extend diagonally upward with respect to the base plate portion 3, and may be located inside the inner peripheral surface of the bent portion 6.

（４）図１０及び図１１に示すように、低強度部７は、屈曲部６より板厚を薄く形成されることで構成されてもよい。この場合、ベース板部３、屈曲部６及びアーム板部４の基端部１３が最も厚く形成され、低強度部７が最も薄く形成されるとよい。また、低強度部７とアーム板部４の基端部１３との間には、板厚が徐々に変わる板厚徐変部１４が形成されるとよい。具体的には、低強度部７は、ベース板部３、屈曲部６及びアーム板部４の基端部１３より０から３０％程度薄く形成されるとよい。例えば、低強度部７の板厚が０．８ｍｍに設定される場合、ベース板部３、屈曲部６及びアーム板部４の基端部１３の板厚は１．２ｍｍに設定されるとよい。ベース板部３を厚く形成するため、母材２にベース板部３を溶接するとき、ベース板部３が溶け落ちることを防止でき、溶接性の向上が図れる。 (4) As shown in FIGS. 10 and 11, the low-strength portion 7 may be formed by forming the plate thickness thinner than that of the bent portion 6. In this case, it is preferable that the base plate portion 3, the bent portion 6, and the base end portion 13 of the arm plate portion 4 are formed to be the thickest, and the low strength portion 7 is formed to be the thinnest. Further, it is preferable that a plate thickness gradual change portion 14 whose plate thickness gradually changes is formed between the low strength portion 7 and the base end portion 13 of the arm plate portion 4. Specifically, the low-strength portion 7 may be formed to be about 0 to 30% thinner than the base end portion 13 of the base plate portion 3, the bent portion 6, and the arm plate portion 4. For example, when the plate thickness of the low-strength portion 7 is set to 0.8 mm, the plate thickness of the base plate portion 3, the bent portion 6, and the base end portion 13 of the arm plate portion 4 may be set to 1.2 mm. .. Since the base plate portion 3 is formed thick, it is possible to prevent the base plate portion 3 from melting down when the base plate portion 3 is welded to the base material 2, and the weldability can be improved.

また、上述の実施の形態では、母材２がアクスルケース等の車両部品である場合について述べたが、これに限るものではない。母材２は船舶、航空機、建設機械、建築物等の他の部品等であってもよい。 Further, in the above-described embodiment, the case where the base material 2 is a vehicle part such as an axle case has been described, but the present invention is not limited to this. The base material 2 may be another part such as a ship, an aircraft, a construction machine, or a building.

また、上述した数値はあくまで例示であり、適宜変更可能である。 In addition, the above-mentioned numerical values are merely examples and can be changed as appropriate.

前述の各実施形態の構成は、特に矛盾が無い限り、部分的にまたは全体的に組み合わせることが可能である。本開示の実施形態は前述の実施形態のみに限らず、特許請求の範囲によって規定される本開示の思想に包含されるあらゆる変形例や応用例、均等物が本開示に含まれる。従って本開示は、限定的に解釈されるべきではなく、本開示の思想の範囲内に帰属する他の任意の技術にも適用することが可能である。 The configurations of each of the above embodiments can be combined partially or wholly, unless otherwise inconsistent.
