Description

この発明は、自動車のドア開口等に装着されるトリムに関し、特にはその芯材として埋設される金属製のトリム用インサートの改良に関する。   The present invention relates to a trim mounted on a door opening or the like of an automobile, and more particularly, to an improvement of a metal trim insert embedded as a core material thereof.

トリムは、例えば自動車のボディのドア開口部に取り付けられるいわゆるウェザーストリップのように、緩衝材、装飾材及びシール材として用いられている。この種トリムはゴムや合成樹脂の長尺成形品の内部にしばしば形状保持のための芯材として板金製のインサートが埋設される。   The trim is used as a cushioning material, a decoration material, and a sealing material, for example, a so-called weather strip attached to a door opening of a vehicle body. In this type of trim, a sheet metal insert is often embedded in a long molded product of rubber or synthetic resin as a core material for shape retention.

トリムに埋設される板金製インサートは、例えば図７に符号１１０で示すように、所定間隔で並列された骨片部１１１，１１１と前記骨片部１１１を長手方向に連結するボンド部１１２とからなる。このトリム用インサート１１０は、平板状に打ち抜き成形されていて、通常、トリム本体の押出成形時に平板状で供給されて一体成形により埋設された後、曲げ加工機等によりトリムの幅方向に曲げ加工され、例えば図８のような所定の断面形状のトリム１００に形成される。図８において、符号１０１は成形品本体部、１０２は自動車のドア開口部に形成されたフランジに取り付けられる嵌着部、１０３，１０４はそのリップ部、１０５はドアパネルに弾性的に当接して該ドアパネルとドアの開口部間の緩衝及びシールをするシール部である。   The sheet metal insert embedded in the trim includes, for example, bone pieces 111 and 111 arranged in parallel at a predetermined interval and a bond portion 112 that connects the bone pieces 111 in the longitudinal direction, as indicated by reference numeral 110 in FIG. Become. The trim insert 110 is stamped and formed into a flat plate shape. Usually, the trim insert 110 is supplied in a flat plate shape when the trim body is extruded and embedded by integral molding, and then bent in the width direction of the trim by a bending machine or the like. For example, the trim 100 having a predetermined cross-sectional shape as shown in FIG. 8 is formed. In FIG. 8, reference numeral 101 denotes a molded product main body, 102 denotes a fitting portion attached to a flange formed at the door opening of an automobile, 103 and 104 denote lip portions thereof, and 105 denotes elastic contact with the door panel. It is a seal part which buffers and seals between a door panel and the opening part of a door.

上のように、トリム用インサートは、長尺のトリム成形品とともに一体成形され曲げ加工される。そして、トリムの装着箇所ではトリムとしての嵌着力を維持しなければならないものである。従って、トリム用インサートは曲げ加工されたトリムの芯材として形状保持力を有することは当然であるが、トリム成形品の押出成形時には押出材料の剪断抵抗にも十分耐えることができる剛性を備えなければならない。   As described above, the trim insert is integrally formed and bent together with a long trim molded product. And in the installation location of a trim, the fitting force as a trim must be maintained. Therefore, it is natural that the trim insert has shape retention as the core material of the trimmed trim, but it must have sufficient rigidity to withstand the shear resistance of the extruded material when the trim molded product is extruded. I must.

一般に、この種インサート１１０の骨片部１１１は幅が２ないし３ｍｍで長さ（インサート全体としては幅方向の大きさ）が２０ないし４０ｍｍという細長い形状であるので、厚みとしてはある程度のものが必要で、０．４ないし０．５ｍｍ厚の板金が使用されるが、図９に示すトリム用インサート１１０Ａのように、骨片部１１１の一面側に突条部１１５を長さ方向に形成することによって、前記骨片部１１１の剛性、強度等の機能を向上させて板金の厚みを減らすことができる（例えば、特許文献１参照。）。   In general, the bone fragment 111 of this type of insert 110 has an elongated shape with a width of 2 to 3 mm and a length (size in the width direction as a whole of the insert) of 20 to 40 mm. In this case, a sheet metal having a thickness of 0.4 to 0.5 mm is used. However, like the trim insert 110 </ b> A shown in FIG. 9, the protrusion 115 is formed in the length direction on one surface side of the bone fragment 111. Thus, functions such as rigidity and strength of the bone fragment 111 can be improved to reduce the thickness of the sheet metal (see, for example, Patent Document 1).

しかるに、トリム成形品の軽量化あるいはコスト削減さらには材料資源の有効利用等の要請から、インサートに使用する板金の厚みをより薄くすることが望まれている。しかしながら、前記インサート１１０Ａのような構成では、さらに板金の厚みを減らした場合、骨片部１１１に突条部１１５が形成されない一般的なインサート１１０に比してトリム成形品の軽量化やコスト削減等を実現することができるものの、骨片部１１１の剛性や強度等を十分に確保することができず、トリム１００の一体押出成形時の樹脂圧によって骨片部１１１が変形して並列状態が乱れてしまいインサートとしての機能を損なうおそれがある。そこで、近年では、インサートの板金の厚みを増やすことなく、骨片部１１１の一面側に突条部１１５が形成されたインサート１１０Ａよりも剛性や強度等を向上させることができるトリム用インサートが切望されている。
特開２００３−２００７９１号公報 However, it is desired to reduce the thickness of the sheet metal used for the insert in order to reduce the weight of the trim molded product, reduce the cost, and effectively use material resources. However, in the configuration such as the insert 110A, when the thickness of the sheet metal is further reduced, the trim molded product is reduced in weight and cost as compared with the general insert 110 in which the protrusion 115 is not formed on the bone fragment 111. However, the rigidity and strength of the bone fragment portion 111 cannot be sufficiently ensured, and the bone fragment portion 111 is deformed by the resin pressure at the time of integral extrusion molding of the trim 100 so that the parallel state is obtained. There is a risk that the function as an insert may be impaired. Therefore, in recent years, a trim insert that can improve the rigidity, strength, and the like of the insert 110A in which the protrusion 115 is formed on one surface side of the bone fragment 111 without increasing the thickness of the sheet metal of the insert is eagerly desired. Has been.

図１及び図２に示す本発明の一実施例に係る板金製のトリム用インサート１０は、打ち抜き成形によって所定間隔で並列された平板形状の骨片部１１がボンド部１２を介して連接されたものであって、前記骨片部１１が第一骨片部２０と第二骨片部３０とが交互に形成されてなるもである。このトリム用インサート１０において、各骨片部１１では、両端部がそれぞれ面取りして形成されている。   The sheet metal trim insert 10 according to one embodiment of the present invention shown in FIG. 1 and FIG. 2 has a plate-shaped bone fragment portion 11 arranged in parallel at a predetermined interval by punching and connected via a bond portion 12. The bone fragment portion 11 is formed by alternately forming the first bone fragment portion 20 and the second bone fragment portion 30. In the trim insert 10, each bone piece portion 11 is formed by chamfering both end portions.

実施例では、骨片部１１の長さ（トリム用インサート１０の幅）が３２．０ｍｍ、幅が２．０ｍｍ、厚さが０．３５ｍｍ、各骨片部１１（第一骨片部２０と第二骨片部３０）の間隔（ボンド部１２の幅）が１．４ｍｍ、骨片部１１の端部の幅が１．２ｍｍ、骨片部１１の面取り部分の長さが１．０ｍｍで構成される。   In the embodiment, the length of the bone fragment portion 11 (the width of the trim insert 10) is 32.0 mm, the width is 2.0 mm, the thickness is 0.35 mm, and each bone fragment portion 11 (with the first bone fragment portion 20 and The distance between the second bone fragment portions 30) (the width of the bond portion 12) is 1.4 mm, the width of the end portion of the bone fragment portion 11 is 1.2 mm, and the length of the chamfered portion of the bone fragment portion 11 is 1.0 mm.

第一骨片部２０は、図１，２に示すように、上面１１Ａ側の長さ方向ａに形成された上側突条部２５を有する。図示の上側突条部２５は、第一骨片部２０の一側端部近傍から他側端部近傍まで直線状に下面１１Ｂと一体に上面１１Ａ側に突出して形成されている。また、実施例の上側突条部２５では、幅が１．０ｍｍ、上面１１Ａからの突出高さｂが０．１５ｍｍである。なお図示しないが、上側突条部２５は、第一骨片部２０の両端まで形成しても構わない。   As shown in FIGS. 1 and 2, the first bone fragment 20 has an upper ridge 25 formed in the length direction a on the upper surface 11 </ b> A side. The illustrated upper ridge portion 25 is formed so as to project linearly from the vicinity of one side end portion of the first bone piece portion 20 to the vicinity of the other side end portion and integrally with the lower surface 11B toward the upper surface 11A side. Moreover, in the upper side protrusion part 25 of an Example, the width | variety is 1.0 mm and the protrusion height b from 11 A of upper surfaces is 0.15 mm. Although not shown, the upper protrusion 25 may be formed up to both ends of the first bone fragment 20.

第二骨片部３０は、図１，２に示すように、下面１１Ｂ側の長さ方向ａに形成された下側突条部３５を有する。図示の下側突条部３５は、第二骨片部３０の一側端部近傍から他側端部近傍まで直線状に上面１１Ａと一体に下面１１Ｂ側に突出して形成されており、特に、前記第一骨片部２０の上側突条部２５と同一の長さで構成される。また、実施例下側突条部３５では、幅が１．０ｍｍ、下面１１Ｂからの突出高さｃが０．１５ｍｍである。なお図示しないが、下側突条部３５は、第二骨片部３０の両端まで形成しても構わない。   As shown in FIGS. 1 and 2, the second bone fragment 30 has a lower protrusion 35 formed in the length direction a on the lower surface 11 </ b> B side. The illustrated lower ridge 35 is formed so as to protrude linearly from the vicinity of one side end of the second bone piece 30 to the vicinity of the other end and to the lower surface 11B integrally with the upper surface 11A. The length is the same as that of the upper ridge portion 25 of the first bone piece portion 20. Moreover, in the example lower side protrusion 35, the width is 1.0 mm, and the protruding height c from the lower surface 11B is 0.15 mm. Although not shown, the lower protrusion 35 may be formed up to both ends of the second bone fragment 30.

トリム用インサート１０を構成する板金は、鉄板、アルミニウム板、銅板、ステンレス等の各種合金板よりなり、平板をプレス切断加工して骨片部１１及びボンド部１２が形成される。また、第一及び第二骨片部２０，３０の上側突条部２５及び下側突条部３５は同じプレス機械内で同時又は順次連続して形成される。   A sheet metal constituting the trim insert 10 is made of various alloy plates such as an iron plate, an aluminum plate, a copper plate, and stainless steel, and the bone piece portion 11 and the bond portion 12 are formed by press-cutting the flat plate. Further, the upper and lower ridge portions 25 and 35 of the first and second bone fragment portions 20 and 30 are formed simultaneously or sequentially in the same press machine.

図３に図示したトリム用インサート１０Ａは、請求項２の発明として規定したように、第一骨片部２０と第二骨片部３０との間に成形後に破断される破断ボンド部１３を形成したものである。破断ボンド部１３は、ボンド部１２より幅狭に形成され、トリム成形品と一体成形された後の曲げ加工時に切断されるように構成される。破断ボンド部１３を形成することにより、当該トリム用インサートに生じる枝流れを回避することができるとともに、前記したトリム本体との一体成形時に骨片部１１が押出材料の剪断抵抗に耐え変形を防止することができ、さらに、トリムとして車両への取り付ける際には破断されるので、屈曲性が向上する。   The trim insert 10 </ b> A shown in FIG. 3 forms a fracture bond portion 13 that is fractured after molding between the first bone piece portion 20 and the second bone piece portion 30 as defined in the invention of claim 2. It is a thing. The fracture bond portion 13 is formed to be narrower than the bond portion 12 and is configured to be cut during bending after being integrally formed with the trim molded product. By forming the fracture bond portion 13, branch flow generated in the trim insert can be avoided, and the bone fragment portion 11 resists the shear resistance of the extruded material and prevents deformation when integrally formed with the trim body. Furthermore, since it is broken when it is attached to the vehicle as a trim, the flexibility is improved.

図４に図示したトリム用インサート１０Ｂは、請求項３の発明として規定したように、破断ボンド部１３（１３Ａ、１３Ｂ）を第一骨片部２０及び第二骨片部３０の両端部近傍に形成したものである。このように、第一骨片部２０及び第二骨片部３０の両端部近傍に破断ボンド部１３Ａ，１３Ｂを形成することにより、骨片部１１がトリムとの一体成形時により変形しにくくなる。   The trim insert 10B shown in FIG. 4 has the fracture bond portion 13 (13A, 13B) in the vicinity of both end portions of the first bone piece portion 20 and the second bone piece portion 30 as defined in the invention of claim 3. Formed. As described above, by forming the fracture bond portions 13A and 13B in the vicinity of both end portions of the first bone piece portion 20 and the second bone piece portion 30, the bone piece portion 11 is less likely to be deformed when integrally formed with the trim. .

図５に図示したトリム用インサート１０Ｃは、請求項４の発明として規定したように、第一骨片部２０と第二骨片部３０との間に長さ方向ａに対して傾斜状に連結する傾斜ボンド部１４を形成したものである。この傾斜ボンド部１４は、図示の如く骨片部１１の長さ方向ａに対して傾斜して形成されているため、当該インサート１０Ｃの屈曲時に傾斜するため、第一骨片部２０と第二骨片部３０とを連結した状態でもトリムにおける三次元方向の変形性と屈曲性を維持することができる。   The trim insert 10 </ b> C illustrated in FIG. 5 is connected to the first bone piece portion 20 and the second bone piece portion 30 so as to be inclined with respect to the length direction a as defined in the invention of claim 4. An inclined bond portion 14 is formed. Since the inclined bond portion 14 is formed so as to be inclined with respect to the length direction a of the bone fragment portion 11 as shown in the drawing, the inclined bond portion 14 is inclined when the insert 10C is bent. Even in a state where the bone fragment portion 30 is connected, the three-dimensional deformability and flexibility in the trim can be maintained.

また、この傾斜ボンド部１４は、図示しかつ請求項５の発明として規定したように、第一骨片部２０または第二骨片部３０を介して隣接する各傾斜ボンド部１４Ａ，１４Ｂを、それぞれ長さ方向ａに対して反対方向に傾斜して形成することが好ましい。これにより、トリム本体との一体成形時に不用意な変形の抑制が可能となって、第一骨片部２０と第二骨片部３０とを連結した状態でトリムの三次元方向の変形性と屈曲性とをより向上させることができる。   Further, as shown in the figure and defined as the invention of claim 5, the inclined bond portion 14 includes the inclined bond portions 14 </ b> A and 14 </ b> B adjacent via the first bone piece portion 20 or the second bone piece portion 30. Each of them is preferably formed so as to be inclined in the opposite direction with respect to the length direction a. Thereby, it becomes possible to suppress inadvertent deformation at the time of integral molding with the trim main body, and the deformability in the three-dimensional direction of the trim in a state where the first bone piece portion 20 and the second bone piece portion 30 are connected. Flexibility can be further improved.

次に、この発明のトリム用インサートの圧縮強度（剛性）について、図６に示す測定方法を用いて説明する。この測定方法において、トリム用インサート１０は、トリム成形品とともに一体成形され折り曲げ加工される際の形状と同様に、骨片部１１の長さ方向ａに対して垂直方向に屈曲させてコの字型に変形させたものである。また、図６に示す測定装置５０は、インサート１０の屈曲形状に合わせて所定角度で傾斜した押圧面５１Ａによって所定の加圧力で前記インサート１０を加圧する加圧部材５１と、インサート１０が載置される台座部５２と、インサート１０を前記台座部５２に固定する固定部材５３とを備える。   Next, the compressive strength (rigidity) of the trim insert according to the present invention will be described using the measuring method shown in FIG. In this measuring method, the trim insert 10 is bent in the direction perpendicular to the length direction a of the bone fragment 11 in the same manner as the shape when integrally molded and bent together with the trim molded product. It is transformed into a mold. Further, in the measuring apparatus 50 shown in FIG. 6, a pressing member 51 that pressurizes the insert 10 with a predetermined pressing force by a pressing surface 51A inclined at a predetermined angle according to the bent shape of the insert 10 and the insert 10 are placed. A pedestal 52 to be fixed and a fixing member 53 for fixing the insert 10 to the pedestal 52.

図示の圧縮強度の測定方法は、屈曲させたトリム用インサート１０を骨片部１１の端部を上方に向けた状態で台座部５２に載置し、前記インサート１０の上方から加圧部材５１を下降させて押圧面５１Ａを骨片部１１の両端部に当接させ、前記骨片部１１の両端部を外側に押圧した際の抗力を測定して行われる。   In the illustrated compressive strength measurement method, the bent trim insert 10 is placed on the pedestal portion 52 with the end of the bone fragment portion 11 facing upward, and the pressurizing member 51 is placed above the insert 10. The pressing surface 51 </ b> A is brought into contact with both end portions of the bone fragment portion 11 by being lowered, and the drag force when the both end portions of the bone fragment portion 11 are pressed outward is measured.

この発明のトリム用インサート１０の圧縮強度を測定した結果は、１１．２４（ｋｇｆ）であった。また、第一の比較例として、各骨片部を平板状に形成した（突条部が形成されていない）インサートの圧縮強度を測定した結果、７．７４（ｋｇｆ）であった。さらに、第二の比較例として、各骨片部の一面側に突条部を形成したインサートの圧縮強度を測定した結果、９．６６（ｋｇｆ）であった。なお、インサート１０と第一及び第二比較例のインサートでは、それぞれ板金の厚みや骨片部１１の幅、各骨片部１１の間隔等の条件を同一とした。   The result of measuring the compressive strength of the trim insert 10 of the present invention was 11.24 (kgf). Further, as a first comparative example, the compression strength of the insert in which each bone fragment portion was formed in a flat plate shape (no protrusion was formed) was 7.74 (kgf). Furthermore, as a second comparative example, the result of measuring the compressive strength of the insert having a protrusion formed on one side of each bone fragment was 9.66 (kgf). In the insert 10 and the inserts of the first and second comparative examples, the conditions such as the thickness of the sheet metal, the width of the bone fragments 11, and the interval between the bone fragments 11 were the same.

上記測定結果から、この発明のトリム用インサート１０では、板金の厚み等の条件が同一である場合、圧縮強度が、骨片部に突条部が形成されていない平板状のインサートより４割〜５割程度、骨片部の一面側に突条部が形成されたインサートより１割〜２割程度優れていることがわかった。   From the above measurement results, in the trim insert 10 according to the present invention, when the conditions such as the thickness of the sheet metal are the same, the compressive strength is 40% to that of the flat plate-shaped insert in which the rib portion is not formed. About 50%, it turned out that it is excellent about 10 to 20% from the insert in which the protrusion part was formed in the one surface side of the bone fragment part.

このように、この発明のトリム用インサート１０は、ボンド部１２を介して連接される骨片部１１が、上側突条部２５を有する第一骨片部２０と下側突条部３５を有する第二骨片部３０とを交互に形成して構成されることにより、骨片部が平板状に形成されたインサートや骨片部の一面側に突条部を形成したインサート等の従来品に比して、骨片部１１の剛性及び強度を高めることができる。また特に、実施例のトリム用インサートにあっては、骨片部１１の厚みを、骨片部に突条部が形成されない従来のトリム用インサートにおいて使用される板金の厚み０．５ｍｍに対して０．１５ｍｍ減じた０．３５ｍｍとしても、従来品と遜色ない剛性及び強度を備えることができる。   As described above, in the trim insert 10 according to the present invention, the bone fragment portion 11 connected through the bond portion 12 includes the first bone fragment portion 20 having the upper protrusion portion 25 and the lower protrusion portion 35. By forming the second bone fragment portion 30 alternately, it is possible to use a conventional product such as an insert in which the bone fragment portion is formed in a flat plate shape or an insert in which a ridge portion is formed on one surface side of the bone fragment portion. In comparison, the rigidity and strength of the bone fragment 11 can be increased. In particular, in the trim insert of the embodiment, the thickness of the bone fragment 11 is set to 0.5 mm of the thickness of the sheet metal used in the conventional trim insert in which no protrusion is formed on the bone fragment. Even when 0.35 mm is reduced by 0.15 mm, rigidity and strength comparable to conventional products can be provided.

さらに、このインサート１０では、骨片部１１の上面１１Ａ側に形成された上側突条部２５と骨片部１１の上面１１Ｂ側に形成された下側突条部３５が交互に連接して配置されるので、当該インサート１０の屈曲方向が一方に限定されることがなく、トリム成形品との一体成形を容易に行うことができる。   Further, in the insert 10, the upper ridge portion 25 formed on the upper surface 11 </ b> A side of the bone fragment portion 11 and the lower ridge portion 35 formed on the upper surface 11 </ b> B side of the bone fragment portion 11 are alternately connected. Therefore, the bending direction of the insert 10 is not limited to one, and integral molding with the trim molded product can be easily performed.

なお、本発明のトリム用インサートは、前述の実施例のみに限定されるものではなく、発明の趣旨を逸脱しない範囲において構成の一部を適宜に変更して実施することができる。例えば、実施例では上側及び下側突条部の形状を断面台形状としたが、この形状に限定されず、適宜の形状とすることができる。   It should be noted that the trim insert of the present invention is not limited to the above-described embodiment, and can be implemented by appropriately changing a part of the configuration without departing from the spirit of the invention. For example, in the embodiment, the shape of the upper and lower protrusions is a trapezoidal cross section, but is not limited to this shape, and may be an appropriate shape.
