In addition, the azimuth | direction used by the following description points out the azimuth | direction in the state which attached the door check apparatus 1 to the motor vehicle.

図１に示すように、ドアチェック装置１は、車体に上下のドアヒンジ２、２により開閉可能に枢支されるドア３の開閉動作に対して所定の抵抗力を付与することで、ドア３を任意の開度位置に保持するものであって、図２−６に示すように、前端部（枢着側）が支持ブラケット５を介して車体パネル４に枢着され、後端部がドア３における前端面のドアパネル３１に設けられる通孔３ａを通ってドア３内に進入するリンク６と、ドア３内に取り付けられ、ドア３の開閉動作に伴ってリンク６の表面を摺動するガイドアッセンブリー７と、ドア３の閉鎖時にドアパネル３１の通孔３ａを閉塞するゴム製の弾性カバー８と、ドア３の全開位置を規制する全開ストッパ１０と、を含んで構成される。   As shown in FIG. 1, the door check device 1 applies a predetermined resistance to the opening / closing operation of the door 3 pivotally supported by the upper and lower door hinges 2, 2 on the vehicle body. As shown in FIGS. 2-6, the front end (pivot side) is pivotally attached to the vehicle body panel 4 via the support bracket 5, and the rear end is door 3. The link 6 that enters the door 3 through the through-hole 3a provided in the door panel 31 on the front end surface, and the guide assembly that is attached to the door 3 and slides on the surface of the link 6 as the door 3 opens and closes. 7, a rubber elastic cover 8 that closes the through hole 3 a of the door panel 31 when the door 3 is closed, and a fully open stopper 10 that restricts the fully open position of the door 3.

リンク６は、主に図６から理解できるように、１枚の金属板６１の表面にモールド成形等で合成樹脂材６２を被覆することで形成され、長手方向（前後方向（図６において左右方向））の前端部に形成された枢支部６３が上下方向を向くシャフト９により車体パネル４に固定される支持ブラケット５に枢着される。   As can be understood mainly from FIG. 6, the link 6 is formed by covering the surface of one metal plate 61 with a synthetic resin material 62 by molding or the like, and is formed in a longitudinal direction (front-rear direction (left-right direction in FIG. 6)). )) Is pivotally attached to a support bracket 5 fixed to the vehicle body panel 4 by a shaft 9 facing in the vertical direction.

リンク６の枢支部６３には、シャフト９が挿入される軸孔６３ａが形成され、同じく枢支部６３よりも若干後部寄りには、弾性カバー８をリンク６に固定するための固定部６４が合成樹脂材６２により形成され、同じく後端部には、リンク６と別部材で形成された全開ストッパ１０が固定され、また、固定部６４と全開ストッパ１０との間の領域には、ドア３の開閉動作に伴って、ガイドアッセンブリー７の後述のシュー１４、１５が摺動するディテント部６５が合成樹脂材により形成される。   A shaft hole 63 a into which the shaft 9 is inserted is formed in the pivotal support part 63 of the link 6, and a fixing part 64 for fixing the elastic cover 8 to the link 6 is combined slightly behind the pivotal support part 63. A fully open stopper 10 formed of a resin material 62 and also formed of a separate member from the link 6 is fixed to the rear end, and a region between the fixed portion 64 and the fully open stopper 10 is fixed to the door 3. Along with the opening / closing operation, a detent portion 65 on which shoes 14 and 15 described later of the guide assembly 7 slide is formed of a synthetic resin material.

ディテント部６５は、ドア３が全閉位置と僅かに開いた位置の範囲にあるとき、シュー１４、１５が接触する平坦部６５ａと、当該平坦部６５ａよりも厚さが厚くなるように平坦部６５ａの後側に連続形成され、ドア３が半開位置（乗員が乗降可能な開度）と全開位置（図５に示す位置）との間にあるとき、シュー１４、１５が接触する隆起部６５ｂを有し、隆起部６５ｂの表面は、シュー１４、１５との間に作用する抵抗力を増大させるように長手方向に沿って略波形状に形成される。なお、ディテント部６５は、左右方向の幅Ｗ３（図３参照）が長手方向に沿って均一になるように形成されている。
なお、固定部６４については、後で詳細に説明する。 When the door 3 is in the range between the fully closed position and the slightly opened position, the detent portion 65 has a flat portion 65a with which the shoes 14 and 15 are in contact, and a flat portion so that the thickness is thicker than the flat portion 65a. When the door 3 is between the half-open position (opening degree at which an occupant can get on and off) and the fully-open position (position shown in FIG. 5), the raised portion 65b with which the shoes 14 and 15 come into contact is formed. The surface of the raised portion 65 b is formed in a substantially wave shape along the longitudinal direction so as to increase the resistance force acting between the shoes 14 and 15. The detent portion 65 is formed so that the width W3 in the left-right direction (see FIG. 3) is uniform along the longitudinal direction.
The fixing unit 64 will be described in detail later.

ガイドアッセンブリー７は、図２、８に示すように、上下２本のボルト１１によりドアパネル３１の内面に固定される金属製のケース１２と、ケース１２に進入しているリンク６のディテント部６５を上下から挟みようにして、ケース１２内に収容された上下のシュー１４、１５と、ケース１２内に収容され、シュー１４、１５をリンク６のディテント部６５に向けて付勢する上下のコイルばね１６、１７と、ケース１２の後面の開口を閉塞する金属製のカバー１３とを有する。   As shown in FIGS. 2 and 8, the guide assembly 7 includes a metal case 12 fixed to the inner surface of the door panel 31 by two upper and lower bolts 11, and a detent portion 65 of the link 6 entering the case 12. The upper and lower shoes 14 and 15 housed in the case 12 and the upper and lower coil springs housed in the case 12 and biasing the shoes 14 and 15 toward the detent portion 65 of the link 6 so as to be sandwiched from above and below. 16 and 17 and a metal cover 13 that closes the opening on the rear surface of the case 12.

ケース１２及びカバー１３には、リンク６をケース１２内に進入させるための正面視矩形の通孔１２ａ及び１３ａが設けられる。
ガイドアッセンブリー７は、主に図７、８に示すように、ケース１２の通孔１２ａがドアパネル３１の通孔３ａと重なり合うようにして、ドアパネル３１の内面に固定される。 The case 12 and the cover 13 are provided with through holes 12 a and 13 a having a rectangular shape in front view for allowing the link 6 to enter the case 12.
As shown mainly in FIGS. 7 and 8, the guide assembly 7 is fixed to the inner surface of the door panel 31 so that the through hole 12 a of the case 12 overlaps the through hole 3 a of the door panel 31.

上下のシュー１４、１５は、互いに上下に点対称形状であって、ケース１２内に進入しているリンク６のディテント部６５を摺動する摺動部１４ａ、１５ａと、摺動部１４ａ、１５ａの一側部にあって、リンク６の側面に接触することでリンク６の横振れを抑制するガイド部１４ｂ、１５ｂとを有し、ドア３の開閉動作に伴って、摺動部１４ａ、１５ａがリンク６のディテント部６５を摺動すると共に、ディテント部６５の隆起部６５ｂとの間に作用する抵抗力によってドア３を任意の開度位置に保持する。   The upper and lower shoes 14 and 15 are point-symmetric with respect to each other, and slide parts 14a and 15a that slide on the detent part 65 of the link 6 that has entered the case 12, and the slide parts 14a and 15a. 1 and has guide portions 14b and 15b that suppress lateral vibration of the link 6 by contacting the side surface of the link 6, and the sliding portions 14a and 15a according to the opening / closing operation of the door 3. Slides on the detent portion 65 of the link 6 and holds the door 3 at an arbitrary opening position by a resistance force acting between the raised portion 65 b of the detent portion 65.

なお、シュー１４、１５のガイド部１４ｂ、１５ｂは、リンク６の横振れを抑制するものであるから、図７に示すように、ガイド部１４ｂとガイド部１５ｂとの左右方向の間隔Ｗ４は、リンク６のディテント部６５の幅Ｗ３よりも僅かに大きくなるように設定される。   Since the guide portions 14b and 15b of the shoes 14 and 15 suppress the lateral shake of the link 6, as shown in FIG. 7, the distance W4 between the guide portion 14b and the guide portion 15b in the left-right direction is The width is set to be slightly larger than the width W3 of the detent portion 65 of the link 6.

ガイドアッセンブリー７のリンク６に対するアッセンブリーは、リンク６に全開ストッパ１０を固定する前の段階で、リンク６の後端部からケース１２の通孔１２ａ、シュー１４、１５間、及びカバー１３の通孔１３ａに進入させることで行われる。   The assembly of the guide assembly 7 with respect to the link 6 is performed before the fully open stopper 10 is fixed to the link 6, from the rear end portion of the link 6 to between the through holes 12 a of the case 12, the shoes 14, 15, and the cover 13. This is done by entering 13a.

Further, the dimension W1 (see FIG. 10) in the left-right direction (the direction orthogonal to the longitudinal direction of the link 6 and the axial direction of the shaft 9) is wider than the width W3 of the detent portion 65 of the link 6. It is formed.

第２鍔部６４ｂは、上下方向の寸法Ｈ２（図９参照）が第１鍔部６４ａの寸法Ｈ１よりも大きく、かつディテント部６５における隆起部６５ｂの厚さＴ３（図４参照）と略同一であり、また、左右方向の寸法Ｗ２（図１０参照）がディテント部６５の幅Ｗ３よりも幅広になるように形成される。   The second flange portion 64b has a vertical dimension H2 (see FIG. 9) larger than the dimension H1 of the first flange portion 64a, and is substantially the same as the thickness T3 (see FIG. 4) of the raised portion 65b in the detent portion 65. Further, the horizontal dimension W2 (see FIG. 10) is formed so as to be wider than the width W3 of the detent portion 65.

嵌合部６４ｃは、左右方向の幅がディテント部６５の幅Ｗ３と略同じで、また、厚さがディテント部６５の平坦部６５ａの厚さと略同じになるように形成される。   The fitting part 64c is formed so that the width in the left-right direction is substantially the same as the width W3 of the detent part 65 and the thickness is substantially the same as the thickness of the flat part 65a of the detent part 65.

弾性カバー８は、ドア３の閉鎖時、ドアパネル３１の通孔３ａを完全に閉塞するものであるから、図１１に示すように、その外形は少なくとも通孔３ａよりも大きい矩形形状であって、中央部分が前方（リンク６の枢支部６３を向く方で、図１１（ｂ）、（ｅ）において左方）へ皿状に凹んだ矩形皿状部８１と、当該矩形皿状部８１の外周縁から後方へ向けて所定量延伸し、ドア３の全閉時にドアパネル３１の外面に接触する外周縁部８２とを有している。矩形皿状部８１の中央部分には、他の部位よりも肉厚で、かつリンク６の第１鍔部６４ａと第２鍔部６４ｂとの間の距離に相当する厚さの厚肉部８４が設けられる。この厚肉部８４の中央部には、開口寸法がリンク６の固定部６４における嵌合部６４ｃの外形寸法と略同一寸法の矩形の嵌合孔８３が設けられる。   Since the elastic cover 8 completely closes the through hole 3a of the door panel 31 when the door 3 is closed, as shown in FIG. 11, the outer shape is a rectangular shape larger than at least the through hole 3a. A rectangular dish-shaped part 81 whose center part is recessed in a dish shape toward the front (the direction facing the pivotal support part 63 of the link 6 and to the left in FIGS. 11B and 11E), and the outside of the rectangular dish-shaped part 81 A predetermined amount extends from the periphery to the rear, and has an outer periphery 82 that contacts the outer surface of the door panel 31 when the door 3 is fully closed. The central portion of the rectangular dish-shaped portion 81 is thicker than other portions and has a thick portion 84 having a thickness corresponding to the distance between the first flange portion 64a and the second flange portion 64b of the link 6. Is provided. A rectangular fitting hole 83 having an opening dimension that is substantially the same as the outer dimension of the fitting part 64 c in the fixing part 64 of the link 6 is provided in the central part of the thick part 84.

弾性カバー８のリンク６に対する組付けは、リンク６の枢支部６３に支持ブラケット５に連結する前の段階で、リンク６を枢支部６３の方から弾性カバー８の嵌合孔８３に弾性変形させながら差し込んで、主に図９、１０に２点鎖線で示すように、厚肉部８４をリンク６の第１鍔部６４ａと第２鍔部６４ｂ間に嵌合させることによって達成される。   When the elastic cover 8 is attached to the link 6, the link 6 is elastically deformed from the pivot 63 to the fitting hole 83 of the elastic cover 8 before being connected to the support bracket 5 to the pivot 63 of the link 6. This is achieved by inserting the thick wall portion 84 between the first flange portion 64a and the second flange portion 64b of the link 6, mainly as shown by a two-dot chain line in FIGS.

弾性カバー８が固定部６４に嵌合固定されている状態においては、図９、１０に２点鎖線で示すように、弾性カバー８の厚肉部８４が、左右方向の寸法Ｗ１がリンク６の幅Ｗ３よりも大きい第１鍔部６４ａと、左右方向の寸法Ｗ２がリンク６の幅Ｗ３よりも幅広で、かつ高さの寸法Ｈ２がアーム６の厚さよりも大きい第２鍔部６４ｂとの間に挟み込まれた状態で、嵌合孔８３が嵌合部６４ｃに外嵌している。これにより、リンク６に固定された弾性カバー８は、その前方移動が第１鍔部６４ａにより規制され、後方移動が第２鍔部６４ｂにより規制されることから、弾性カバー８は、リンク６の固定部６４に確実に嵌合固定されて固定部６４から簡単に外れるようなことはない。   In a state in which the elastic cover 8 is fitted and fixed to the fixing portion 64, the thick portion 84 of the elastic cover 8 has a horizontal dimension W1 of the link 6 as shown by a two-dot chain line in FIGS. Between the first collar part 64a larger than the width W3 and the second collar part 64b whose lateral dimension W2 is wider than the width W3 of the link 6 and whose height dimension H2 is larger than the thickness of the arm 6. The fitting hole 83 is externally fitted to the fitting portion 64c while being sandwiched between the two. As a result, the elastic cover 8 fixed to the link 6 is restricted in its forward movement by the first flange part 64a and its rearward movement is restricted by the second flange part 64b. The fixing part 64 is securely fitted and fixed and does not easily come off the fixing part 64.

さらに、図１１（ｅ）に示すように、弾性カバー８における矩形皿状部８１は、外周から中央部に向けて厚さが漸減するように形成される。外周縁部８２は、矩形皿状部８１との境目に段差部８５が形成されることで、厚さｔ１が矩形皿状部８１の最も厚さが厚い外周部分の厚さｔ２よりも厚くなるように形成される。   Further, as shown in FIG. 11 (e), the rectangular dish-shaped portion 81 in the elastic cover 8 is formed so that the thickness gradually decreases from the outer periphery toward the central portion. The outer peripheral edge portion 82 is formed with a stepped portion 85 at the boundary with the rectangular dish-shaped portion 81, so that the thickness t1 is thicker than the thickness t2 of the outermost peripheral portion of the rectangular dish-shaped portion 81. Formed as follows.

ドアチェック装置１の自動車への組付けは、次のようにして行われる。先ず、図１２に示すように、リンク６に支持ブラケット５、ガイドアッセンブリー７、弾性カバー８及び全開ストッパ１０を組み付けたアッセンブリー状態で、図１３に示すように、ドアチェック装置１の前端部をドア１の内側からドアパネル３１の通孔３ａに挿入し、図１４−１６に示すように、弾性カバー８を弾性変形させつつ通孔３ａを通過させる。これにより、図１７に示すように、支持ブラケット５及び弾性カバー８は、ドア３の外側に導出される。その後に、支持ブラケット５を車体パネル４に固定し、ガイドアッセンブリー７のケース１２をドアパネル３１の内面に固定する。   The door check device 1 is assembled to the vehicle as follows. First, as shown in FIG. 12, in the assembled state in which the support bracket 5, the guide assembly 7, the elastic cover 8, and the fully open stopper 10 are assembled to the link 6, as shown in FIG. 1 is inserted into the through hole 3a of the door panel 31, and as shown in FIGS. 14-16, the elastic cover 8 is elastically deformed and passed through the through hole 3a. Thereby, as shown in FIG. 17, the support bracket 5 and the elastic cover 8 are led out to the outside of the door 3. Thereafter, the support bracket 5 is fixed to the vehicle body panel 4, and the case 12 of the guide assembly 7 is fixed to the inner surface of the door panel 31.

この場合、弾性カバー８は、その外形寸法がドアパネル３１の通孔３ａの孔寸法よりも大きいため、ドアパネル３１の通孔３ａを通過する際、図１４−１６に示すように、矩形皿状部８１及び外周縁部８２の外形が縮小するように弾性変形する。   In this case, the elastic cover 8 has an outer dimension larger than the hole dimension of the through hole 3a of the door panel 31, so that when passing through the through hole 3a of the door panel 31, as shown in FIG. 81 and the outer peripheral edge 82 are elastically deformed so that the outer shapes thereof are reduced.

しかし、本実施形態においては、矩形皿状部８１の厚さが外周から中央部に向けて漸減するように形成されているため、矩形皿状部８１が通孔３ａを通過するための弾性変形を容易にしている。また、厚肉部８４の厚さが矩形皿状部８１よりも厚く形成されているため、矩形皿状部８１の変形は厚肉部８４には伝達され難い。これにより、嵌合孔８３が固定部６４から抜け出て、弾性カバー８が固定部６４から外れてしまうような事態は阻止される。   However, in the present embodiment, since the thickness of the rectangular dish-shaped portion 81 is formed so as to gradually decrease from the outer periphery toward the central portion, the elastic deformation for allowing the rectangular dish-shaped portion 81 to pass through the through hole 3a. Making it easy. Further, since the thick portion 84 is formed thicker than the rectangular dish-shaped portion 81, the deformation of the rectangular dish-shaped portion 81 is difficult to be transmitted to the thick portion 84. As a result, a situation in which the fitting hole 83 comes out of the fixed portion 64 and the elastic cover 8 is detached from the fixed portion 64 is prevented.

次に、ドア３の開閉時における弾性カバー８の作用について説明する。
図５に示すように、ドア３が開いている場合には、弾性カバー８は、リンク６の固定部６４に固定されて、ドアパネル３１の外面から離れている。この状態でドア３を閉じると、ガイドアッセンブリー７のシュー１４、１５がリンク６のディテント部６５を前方へ向けて摺動し、図３、４に示すように、ドア３が全閉状態となると、主に図７、８に示すように、弾性カバー８は、ドアパネル３の外面に接触する。 Next, the operation of the elastic cover 8 when the door 3 is opened and closed will be described.
As shown in FIG. 5, when the door 3 is open, the elastic cover 8 is fixed to the fixing portion 64 of the link 6 and separated from the outer surface of the door panel 31. When the door 3 is closed in this state, the shoes 14 and 15 of the guide assembly 7 slide forward with the detent portion 65 of the link 6, and the door 3 is fully closed as shown in FIGS. As shown mainly in FIGS. 7 and 8, the elastic cover 8 contacts the outer surface of the door panel 3.

弾性カバー８がドアパネル３１の外面に接触して押し付けられると、図７、８から理解できるように、弾性カバー８は、矩形皿状部８１が前方へ向けて弾性変形すると共に、外周縁部８２がドアパネル３１の外面に接触して、ドアパネル３１の通孔３ａを閉塞する。   When the elastic cover 8 is pressed against the outer surface of the door panel 31, as can be understood from FIGS. 7 and 8, the elastic cover 8 is elastically deformed toward the front and the outer peripheral edge 82. Contacts the outer surface of the door panel 31 and closes the through hole 3 a of the door panel 31.

この場合、弾性カバー８の矩形皿状部８１の厚さが中央部に向けて漸減する形状であるため、矩形皿状部８１は、前方、すなわちドア３の閉方向へ容易に弾性変形することができる。また、外周縁部８２の厚さが矩形皿状部８１よりも厚いため、矩形皿状部８１の弾性変形が外周縁部８２に伝達され難くなり、外周縁部８２がドアパネル３１の外面に確実に接触することができる。これにより、自動車の走行時に発生する風が通孔３ａを通ってドア３内に進入する際に発生する風切り音を確実に防止することができる。   In this case, since the thickness of the rectangular dish-shaped portion 81 of the elastic cover 8 is gradually reduced toward the central portion, the rectangular dish-shaped portion 81 can be easily elastically deformed forward, that is, in the closing direction of the door 3. Can do. In addition, since the outer peripheral edge 82 is thicker than the rectangular dish-shaped part 81, the elastic deformation of the rectangular dish-shaped part 81 is difficult to be transmitted to the outer peripheral edge 82, and the outer peripheral edge 82 is reliably attached to the outer surface of the door panel 31. Can contact. Thereby, it is possible to reliably prevent wind noise generated when wind generated when the vehicle travels enters the door 3 through the through hole 3a.
