自動車内には、グローブボックスや、工具等を収容可能な収容スペースが壁部に形成されており、これらの開口部はリッドにより閉じられ、このリッドを着脱可能にして開口部を開閉可能とするリッド開閉装置が設けられている。 In the automobile, a space for accommodating a glove box, tools, etc. is formed in the wall, and these openings are closed by a lid, and the lid can be attached and detached to open and close the opening. A lid opening and closing device is provided.

下記特許文献１には、レバーによって押し引きされ、その一端にラッチが形成された第１リンクを有し、この第１リンクの他端が可撓性を有する連結片を介して、リッドに揺動可能に取付けられたクランクの一端に連結され、このクランクの他端が同じく可撓性を有する連結片を介して、一端にラッチが形成された第２リンクの他端に連結され、これら一対の連結片によって、第１、第２リンクのラッチがリッドの外方に押し出される方向に付勢されており、このラッチがグローブボックス等の開口部周縁に係合して、開口部を閉じた状態にロックするリッドロック機構が開示されている。そして、レバーを引くことにより、第１リンクが連結片を撓ませてクランクを揺動させるとともに、第２リンクも連結片を介してリッドの内側に引き込まれ、リッド両側のラッチが開口部周縁から外れて、リッドをロック状態から解除することが記載されている。

International Publication No. 95/27115 Pamphlet

上記特許文献１のリッドロック機構は、連結片が一旦撓んで元の状態に戻る際の弾性復元力によってラッチが弾性付勢され、その連結片を介して第１リンク、第２リンクがクランクに連結されている。そのため、レバーの押し引き操作を何回も行うと、連結片に曲げ応力が繰返し加わり、次第に劣化してしまい、ラッチを押し出す付勢力が弱まって、開口部をしっかりと閉じた状態にロックすることができず、更には連結片の破損を招く可能性があるという問題があった。 In the lid lock mechanism of Patent Document 1, the latch is elastically urged by the elastic restoring force when the connecting piece is bent and returns to the original state, and the first link and the second link are connected to the crank via the connecting piece. It is connected. Therefore, when the lever is pushed and pulled many times, bending stress is repeatedly applied to the connecting piece, which gradually deteriorates, and the urging force that pushes out the latch weakens to lock the opening in a tightly closed state. In addition, there is a problem that the connecting piece may be damaged.

上記問題を解決すべく連結片を長く成形すると、連結片が撓みやすくなるので劣化や破損を防止するが、その反面連結片の弾性復元力が弱くなり、リンクの連動性も低下してしまう。一方、連結片を短く成形すると、連結片の弾性復元力を強めることができるが、今度は連結片が撓みにくくなり、劣化や破損の恐れが生じてしまうことになる。このように、連結片の弾性復元力でラッチを押し出す場合には、連結片の弾性復元力及び撓みやすさの双方を満足させることが難しかった。 If the connecting piece is formed long to solve the above problem, the connecting piece is easily bent and prevented from being deteriorated or damaged. On the other hand, the elastic restoring force of the connecting piece is weakened, and the linkage of the link is also lowered. On the other hand, when the connecting piece is formed short, the elastic restoring force of the connecting piece can be increased, but this time, the connecting piece becomes difficult to bend, and deterioration or breakage may occur. As described above, when the latch is pushed out by the elastic restoring force of the connecting piece, it is difficult to satisfy both the elastic restoring force and the ease of bending of the connecting piece.

したがって、本発明の目的は、リッドの開閉操作を繰り返し行っても、開口部に係合するラッチをリッドの外側へしっかりと押し出し、開口部を閉じた状態に確実にロックして、リッドの開閉操作がスムーズになされるリッド開閉装置及びその製造方法を提供することにある。 Therefore, the object of the present invention is to push the latch that engages the opening firmly to the outside of the lid even when the opening and closing operation of the lid is repeated, and to securely lock the opening in the closed state.

本発明のリッド開閉装置によれば、反力付与板の弾性復元力により、リンク端部のラッチが、リッドの外方に押し出す方向に弾性付勢される。そのため、開口部をリッドで閉じたとき、リッドの外方に弾性付勢されて押し出されるラッチを開口部に係合させて、リッドを閉じた状態にロックすることができる。また、リッドの表側から操作子を回して、反力付与板の弾性付勢力に抗して、ラッチがリッドの内部に引き込む方向にクランクを回動させることにより、ラッチと開口部との係合を解除してリッドを開くことができる。 According to the lid opening and closing device of the present invention, the latch at the link end is elastically biased in the direction of pushing out outward of the lid by the elastic restoring force of the reaction force applying plate. Therefore, when the opening is closed with the lid, the latch that is elastically urged and pushed outward from the lid can be engaged with the opening to lock the lid in the closed state. In addition, by rotating the operating element from the front side of the lid and rotating the crank in the direction in which the latch is pulled into the lid against the elastic biasing force of the reaction force applying plate, the latch and the opening are engaged. Can be opened to open the lid.

そして、反力付与板は、その一端をクランクに連結され、他端をリンクの中間部に撓んだ状態で連結されて、リンクのラッチをリッドの外方に押し出す方向に弾性付勢しているので、比較的長い湾曲した板材からなり、リッドの開閉に伴って繰り返し撓ませても応力集中による劣化が生じにくく、ラッチをリッドの外方に押出す弾性付勢力が低下することを防止できる。 The reaction force applying plate has one end connected to the crank and the other end connected to the middle portion of the link in a bent state, and elastically urges the link latch to push the lid outward. Therefore, it is made of a relatively long curved plate material, and even if it is repeatedly bent as the lid is opened and closed, it does not easily deteriorate due to stress concentration, and it can prevent the elastic biasing force that pushes the latch outward from the lid. .

The connecting piece 61 is thinner than the link 60 and has flexibility when compared with the thickness of the link 60 when viewed from the direction perpendicular to the back surface of the lid 20. Sometimes it is easy to bend.

リンク６０ａ、６０ｂをガイド部２６で支持することにより、リンク６０ａ、６０ｂをリッド２０裏面に対して一定距離を保って支持することができるので、車室内の壁部１１が複雑な湾曲形状をなし、それに合わせてリッド２０が湾曲している場合でも、リンク６０ａ、６０ｂをスライド可能に保持することが可能となる。 By supporting the links 60a and 60b with the guide portion 26, the links 60a and 60b can be supported with a certain distance from the back surface of the lid 20, so that the wall portion 11 in the vehicle interior has a complicated curved shape. Even when the lid 20 is curved in accordance with this, the links 60a and 60b can be slidably held.

また、ラッチ６２は、リッド２０の開口部１２との係合面の反対側に、その途中から先端に向けて次第に小さくなるテーパ面６２ａが形成されている。これによれば、リッド２０を開口部１２に嵌め込むと、テーパ面６２ａが開口部１２周縁に当接しそのまま押圧され、ラッチ６２がリッド内側に引き込まれ、開口部１２周縁を通過したら、ラッチ６２は弾性付勢されて元の位置に戻る。そのため、操作子３０を回転させてラッチ６２をリッド２０の内側に引き込む必要がなく、開口部１２内周に嵌め込むだけで、間単に開口部１２を閉じた状態にロックすることができる。 Further, the latch 62 is formed with a tapered surface 62 a that gradually decreases from the middle toward the tip on the opposite side of the engagement surface with the opening 12 of the lid 20. According to this, when the lid 20 is fitted into the opening 12, the tapered surface 62 a comes into contact with the peripheral edge of the opening 12 and is pressed as it is, and the latch 62 is pulled inside the lid 12 and passes through the peripheral edge of the opening 12. Is elastically biased and returns to its original position. Therefore, it is not necessary to rotate the operating element 30 and pull the latch 62 into the lid 20, and it is possible to simply lock the opening 12 in the closed state simply by fitting it into the inner periphery of the opening 12.

更に、リンク６０ａ、６０ｂの中間部６３には、少なくとも一方の側面、この実施形態では両側面に突起６４が設けられている。この実施形態の場合、中間部６３に所定間隔をおいて３箇所に形成されている。 Further, the intermediate portions 63 of the links 60a and 60b are provided with projections 64 on at least one side surface, in this embodiment both side surfaces. In the case of this embodiment, the intermediate portion 63 is formed at three positions with a predetermined interval.

クランク５０の対向する連結部５４には、反力付与板７０ａ、７０ｂの一端が薄板のヒンジ部７１を介して連結され、同じ連結部５４に連結されたリンク６０ｂ、６０ａに対して反対方向に伸びている。 One end of the reaction force applying plates 70a and 70b is connected to the opposing connecting portion 54 of the crank 50 via a thin hinge 71, and in the opposite direction to the links 60b and 60a connected to the same connecting portion 54. It is growing.

また、反力付与板７０ａ、７０ｂの他端には、図１、４に示すように、二股状に分かれて軸方向に突出した係合部７２が形成されており、この係合部７２をリンク６０ａ、６０ｂの中間部６３の突起６４に係合させることによって、リンク６０ａ、６０ｂの中間部に反力付与板７０ａ、７０ｂが湾曲した状態で連結されている。 Further, as shown in FIGS. 1 and 4, an engaging portion 72 is formed at the other end of the reaction force applying plates 70 a and 70 b so as to be bifurcated and project in the axial direction. By engaging the protrusions 64 of the intermediate portion 63 of the links 60a and 60b, the reaction force applying plates 70a and 70b are connected to the intermediate portions of the links 60a and 60b in a curved state.

一方の反力付与板７０ａは、一方のリンク６０ａに連結されて、リンク６０ａを外方に押出す方向に付勢し、他方の反力付与板７０ｂは、他方のリンク６０ｂに連結されて、リンク６０ｂを外方に押出す方向に付勢する。 One reaction force application plate 70a is connected to one link 60a and urges the link 60a in the direction of pushing outward, and the other reaction force application plate 70b is connected to the other link 60b. The link 60b is urged in the direction of pushing outward.

すなわち、互いに対をなすリンク６０ａと反力付与板７０ａ、及びリンク６０ｂと反力付与板７０ｂは、クランク５０の対向する連結部５４に連結されているので、図３に示すように、クランク５０を揺動させたときに、反力付与板７０ａ、７０ｂを効果的に撓ませて、リンク６０を外方に押し出す方向に弾性付勢できる。 That is, since the link 60a and the reaction force applying plate 70a and the link 60b and the reaction force applying plate 70b that are paired with each other are connected to the opposing connecting portion 54 of the crank 50, as shown in FIG. Can be elastically biased in the direction of pushing the link 60 outward by effectively bending the reaction force applying plates 70a and 70b.

また、反力付与板７０ａ、７０ｂは、薄板のヒンジ部７１を介して、連結部５４に連結されているので、ヒンジ部７１で屈曲しやすくして、図３に示すように、反力付与板７０ａ、７０ｂを大きく撓みやすくすることができる。 Further, the reaction force applying plates 70a and 70b are connected to the connecting portion 54 via the thin hinge portion 71. Therefore, the reaction force applying plates 70a and 70b are easily bent at the hinge portion 71, as shown in FIG. The plates 70a and 70b can be greatly bent easily.

更に、反力付与板７０ａ、７０ｂは、その断面が矩形状をなしており、かつ、幅広側がリッド２０の裏面に対して垂直方向に位置するように、クランク５０の一端及びリンク６０の中間部６３に連結されている（図１参照）。このため、反力付与板７０の幅広面に対して垂直な方向に撓みやすくなり、繰り返しの屈曲に対しても耐久性を向上させることができる。 Further, the reaction force application plates 70 a and 70 b have a rectangular cross section, and the one end of the crank 50 and the intermediate portion of the link 60 so that the wide side is positioned perpendicular to the back surface of the lid 20. 63 (see FIG. 1). For this reason, it becomes easy to bend in the direction perpendicular | vertical with respect to the wide surface of the reaction force provision board 70, and durability can be improved also with respect to repeated bending.

また、図４に示すように、リンク６０ａ、６０ｂの中間部６３両側が、反力付与板７０ａ、７０ｂの係合部７２で挟まれ、係合部７２が突起６４に係合して、反力付与板７０とリンク６０とが連結されているので、図４（ｂ）に示すように、リンク６０の揺動に伴って反力付与板７０ａ、７０ｂが撓んで反力付与板７０ａ、７０ｂの端部の向きが変わっても、係合部７２はリンク６０側面上を摺動するので、その弾性復元力をリンク６０ａ、６０ｂを押出す方向に効果的に作用させることができる。操作子３０を回すトルクが増大して回しにくくなることもない。 Further, as shown in FIG. 4, both sides of the intermediate portion 63 of the links 60 a and 60 b are sandwiched between the engaging portions 72 of the reaction force applying plates 70 a and 70 b, and the engaging portions 72 engage with the protrusions 64, Since the force application plate 70 and the link 60 are connected, the reaction force application plates 70a and 70b are bent and the reaction force application plates 70a and 70b as the link 60 swings as shown in FIG. Even if the direction of the end portion of the link is changed, the engaging portion 72 slides on the side surface of the link 60, so that the elastic restoring force can be effectively applied in the direction in which the links 60a and 60b are pushed out. The torque for turning the operating element 30 does not increase and it is difficult to turn.

また、二股状の係合部７２を突起６４に係合させるだけで、ワンタッチで簡単に反力付与板７０ａ、７０ｂとリンク６０ａ、６０ｂとを連結することができる。この係合部７２は、例えば、図４（ｃ）に示すような形状をなしている。すなわち、反力付与板７０ａ、７０ｂの他端から、二股状に分かれて軸方向に突出した一対の弾性片７２ａ，７２ａが設けられ、この弾性片７２ａ，７２ａの端部内側から、対向して一対の爪部７２ｂ，７２ｂが形成されている。また、爪部７２ｂにはリンク６０に挿入しやすいように、テーパ面７２ｃが形成されている。これによれば、係合部７２をリンク６０ａ、６０ｂの中間部６３に挿入した後、爪部７２ｂがリンク６０ａ、６０ｂに係合するので、反力付与板７０ａ、７０ｂがリンク６０から抜け外れることを防止できる。 Further, the reaction force applying plates 70a and 70b and the links 60a and 60b can be easily connected with one touch only by engaging the bifurcated engaging portion 72 with the protrusion 64. For example, the engaging portion 72 has a shape as shown in FIG. That is, a pair of elastic pieces 72a and 72a which are bifurcated and protrude in the axial direction are provided from the other ends of the reaction force applying plates 70a and 70b, and are opposed to each other from the inner ends of the elastic pieces 72a and 72a. A pair of claw portions 72b and 72b are formed. Further, the claw portion 72b is formed with a tapered surface 72c so as to be easily inserted into the link 60. According to this, after inserting the engaging portion 72 into the intermediate portion 63 of the links 60a and 60b, the claw portion 72b engages with the links 60a and 60b, so that the reaction force applying plates 70a and 70b come off from the link 60. Can be prevented.

なお、上述したように、リンク６０ａ、６０ｂの中間部６３には、突起６４が所定間隔をおいて３箇所に形成されているので、例えば、クランク５０側の突起６４に係合させると、反力付与板７０ａ、７０ｂの弾性復元力を強め、ラッチ６２側の突起６４に係合させると、反力付与板７０ａ、７０ｂの弾性復元力を弱めることができ、弾性復元力を適度に調整可能となる。 As described above, since the protrusions 64 are formed at three positions at a predetermined interval in the intermediate portion 63 of the links 60a and 60b, for example, when engaged with the protrusions 64 on the crank 50 side, When the elastic restoring force of the force applying plates 70a and 70b is increased and engaged with the protrusions 64 on the latch 62 side, the elastic restoring force of the reaction force applying plates 70a and 70b can be weakened, and the elastic restoring force can be adjusted appropriately. It becomes.

また、この実施形態の場合、リンク６０ａ、６０ｂの一端がクランク５０の一端に連結され、かつ、反力付与板７０ａ、７０ｂの一端がクランク５０の他端に連結され、反力付与板７０ａ、７０ｂの他端がリンク６０ａ、６０ｂの中間部６３とは連結されていない状態で射出成形されており、反力付与板７０ａ、７０ｂの他端をリンク６０ａ、６０ｂの中間部６３に撓んだ状態で連結させることにより、リンク６０ａ、６０ｂのラッチ６２を、リッド２０の外方に押し出す方向に弾性付勢させている。これは、反力付与板７０ａ、７０ｂとリンク６０ａ、６０ｂの中間部６３とを予め連結し、反力付与板７０ａ、７０ｂを湾曲させた状態で成形した場合は、弾性復元力が発生しないからである。 In the case of this embodiment, one end of the links 60a and 60b is connected to one end of the crank 50, and one end of the reaction force applying plates 70a and 70b is connected to the other end of the crank 50, and the reaction force applying plate 70a, The other end of 70b is injection-molded in a state where it is not connected to the intermediate portion 63 of the links 60a and 60b, and the other end of the reaction force applying plates 70a and 70b is bent to the intermediate portion 63 of the links 60a and 60b. By connecting in a state, the latches 62 of the links 60a and 60b are elastically biased in the direction of pushing the lid 20 outward. This is because when the reaction force applying plates 70a and 70b and the intermediate portion 63 of the links 60a and 60b are connected in advance and the reaction force applying plates 70a and 70b are formed in a curved state, no elastic restoring force is generated. It is.

また、この実施形態においては、クランク５０、リンク６０ａ、６０ｂ、及び反力付与板７０ａ、７０ｂが一体成形されている。これによれば、クランク５０、リンク６０ａ、６０ｂ、及び反力付与板７０ａ、７０ｂが一体成形できるので、製造コストを低減でき、組立作業も容易となる。 In this embodiment, the crank 50, the links 60a and 60b, and the reaction force applying plates 70a and 70b are integrally formed. According to this, since the crank 50, the links 60a and 60b, and the reaction force applying plates 70a and 70b can be integrally formed, the manufacturing cost can be reduced and the assembling work can be facilitated.

なお、以上説明した部材は、例えば、ポリオキシメチレン（ＰＯＭ）、ポリアミド（ＰＡ）等の合成樹脂により成形される。 In addition, the member demonstrated above is shape | molded, for example with synthetic resins, such as polyoxymethylene (POM) and polyamide (PA).

次に、上記構成によるリッド開閉装置の組立手順及び作用について説明する。 Next, the assembly procedure and operation of the lid opening / closing device having the above configuration will be described.

まず、リッド２０表側から凹部２４内に、操作子３０を挿入して、その回転軸３３をリッド２０の裏側に突き出し、リッド２０裏側から、台座４０の図示しない突起を貫通孔２５に挿入して、台座４０をリッド２０裏側に回り止めして取付ける。 First, the operation element 30 is inserted into the recess 24 from the front side of the lid 20, and the rotary shaft 33 is projected to the back side of the lid 20, and a projection (not shown) of the base 40 is inserted into the through hole 25 from the back side of the lid 20. The base 40 is attached to the back side of the lid 20 while being prevented from rotating.

次いで、挿通孔５２内周に接着剤を塗布したクランク５０を、その突起５３と回転軸３３の溝部３４とを整合させた後、円弧状リブ４３内に円筒状基部５１を挿入し、操作子３０とクランク５０とを固着する。 Next, after aligning the projection 53 and the groove portion 34 of the rotary shaft 33 with the crank 50 coated with adhesive on the inner periphery of the insertion hole 52, the cylindrical base portion 51 is inserted into the arc-shaped rib 43, and the operator 30 and the crank 50 are fixed.

そして、リンク６０ａ、６０ｂ端部のラッチ６２を、ガイド部２６の挿通孔２７に挿入して、ラッチ６２をスライド可能に支持し、反力付与板７０ａ、７０ｂの係合部７２を、リンク６０ａ、６０ｂの中間部６３の突起６４に係合させると、反力付与板７０ａ、７０ｂがリンク６０ａ、６０ｂの中間部に撓んだ状態で連結され、その弾性復元力によりリンク６０ａ、６０ｂ端部のラッチ６２をリッド２０の外方に押し出す方向に弾性付勢される。 Then, the latches 62 at the ends of the links 60a and 60b are inserted into the insertion holes 27 of the guide part 26, and the latches 62 are slidably supported, and the engaging parts 72 of the reaction force applying plates 70a and 70b are connected to the link 60a. , 60b, the reaction force applying plates 70a, 70b are connected in a bent state to the intermediate portions of the links 60a, 60b, and end portions of the links 60a, 60b by the elastic restoring force. The latch 62 is elastically biased in the direction of pushing the latch 20 outward.

そして、図５、６に示す、車室１０内の壁部１１に形成された開口部１２に適用されることとなる。すなわち、爪部２３を開口部１２の下方周縁に係止させた後、リッド２０を開口部１２に押し込むだけで、ラッチ６２が、テーパ面６２ａを介して開口１２両側周縁に押圧され、リッド２０内側に引き込まれ、そして開口部１２を通過したら再度押し出されて、開口部１２周縁に係合するので、簡単に開口部１２を閉じた状態にロックすることができる（図５参照）。また、開口部１２の両側周縁にそれぞれラッチ６２が係合するので、ガタツキが少なく建付けも良くなる。 And it will be applied to the opening part 12 formed in the wall part 11 in the compartment 10 shown in FIG. That is, after the claw 23 is locked to the lower peripheral edge of the opening 12, the latch 62 is pressed to the peripheral edges of the opening 12 via the tapered surface 62 a simply by pushing the lid 20 into the opening 12. Since it is drawn inward and passes through the opening 12 and is pushed out again and engages with the periphery of the opening 12, the opening 12 can be easily locked in a closed state (see FIG. 5). Further, since the latches 62 are engaged with the peripheral edges on both sides of the opening 12, there is little backlash and the installation is improved.

そして、摘み部３２を把持して操作子３０を回転させると、リンク６０ａ、６０ｂのラッチ６２が共にリッド２０内部に引き込まれ、ラッチ６２と開口部１２両側周縁との係合が解除されて、リッド２０を開くことができる（図６参照）。この際、反力付与板７０ａ、７０ｂは、比較的長い湾曲した板材からなり、リッド２０の開閉に伴って繰り返し撓ませても応力集中による劣化が生じにくく、ラッチ６２をリッド２０の外方に押出す弾性付勢力が低下することを防止する。 When the operator 30 is rotated while holding the knob 32, the latches 62 of the links 60a and 60b are both pulled into the lid 20, and the engagement between the latch 62 and the peripheral edges on both sides of the opening 12 is released. The lid 20 can be opened (see FIG. 6). At this time, the reaction force imparting plates 70a and 70b are made of a relatively long curved plate material, and even if the lid 20 is repeatedly bent as the lid 20 is opened and closed, deterioration due to stress concentration does not easily occur, and the latch 62 is placed outside the lid 20. Prevents the elastic biasing force to be lowered.

なお、開口部１２は、車体パネルと壁部１１との間に形成された収容スペースの開口であり、この収容スペースにはジャッキ等の工具が収容される。この実施形態の場合、車室１０の側壁を開閉ロックするリッドに適用しているが、車室１０の底壁を開閉するリッドや、グローブボックスを開閉するリッドに適用してもよい。 The opening 12 is an opening of an accommodation space formed between the vehicle body panel and the wall portion 11, and a tool such as a jack is accommodated in the accommodation space. In the case of this embodiment, although applied to the lid which opens and closes the side wall of the compartment 10, you may apply to the lid which opens and closes the bottom wall of the compartment 10, and the lid which opens and closes a glove box.

また、この実施形態の場合、ラッチ６２は開口部１２の周縁に係合しているが、例えば、開口部周縁に突出する壁部が形成されている場合には、その壁部にラッチ６２と係合する係合孔を設けておき、これにより開口部１２を閉じた状態にロックしてもよい。 In this embodiment, the latch 62 is engaged with the peripheral edge of the opening 12. For example, when a wall projecting on the peripheral edge of the opening is formed, the latch 62 is connected to the wall. An engagement hole to be engaged may be provided to lock the opening 12 in a closed state.

図７、８には、本発明のリッド開閉装置の他の実施形態が示されている。なお、前記実施形態と実質的に同一部分には同符号を付してその説明を省略する。 7 and 8 show another embodiment of the lid opening / closing device of the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

この実施形態の場合、クランク５０の一方の連結部５４の端部に、クランク５０の長手方向に対して垂直方向に開口した、Ｃ字状の嵌合凹部５４ａが形成されている。また、図７（ｂ）に示すように、嵌合凹部５４ａが形成された連結部５４の高さ方向中間は、所定幅で切欠かれて前記嵌合凹部５４ａと連通した、摺動溝５４ｂが形成されている。そして、リンク６０のラッチ６２とは反対側の端部には、上記実施形態のような連結片６１が形成されず、前記嵌合凹部５４ａに嵌合する大きさで、リンク６０ａ、６０ｂの両側に突出した円柱状の嵌合凸部６１ａが形成されている（図７（ｃ）参照）。リンク６０ａ、６０ｂはラッチ６２寄りの箇所の側面に、ピン状の突起７３が形成され、この突起７３を介して反力付与板７０ａ、７０ｂの一端に連結される。また、反力付与板７０ａ、７０ｂの他端は、ヒンジ部７１を介してクランク５０の連結部５４に連結している。 In the case of this embodiment, a C-shaped fitting recess 54 a that opens in a direction perpendicular to the longitudinal direction of the crank 50 is formed at the end of one connecting portion 54 of the crank 50. Further, as shown in FIG. 7B, the intermediate portion in the height direction of the connecting portion 54 in which the fitting recess 54a is formed has a sliding groove 54b that is notched with a predetermined width and communicates with the fitting recess 54a. Is formed. Further, the connecting piece 61 as in the above-described embodiment is not formed at the end of the link 60 opposite to the latch 62, and the link 60a and 60b are sized to fit into the fitting recess 54a. A cylindrical fitting convex portion 61a that protrudes into the center is formed (see FIG. 7C). The links 60 a and 60 b are formed with pin-shaped protrusions 73 on the side surfaces near the latch 62, and are connected to one ends of the reaction force applying plates 70 a and 70 b via the protrusions 73. The other ends of the reaction force applying plates 70 a and 70 b are connected to the connecting portion 54 of the crank 50 via the hinge portion 71.

そして、嵌合凸部６１ａを嵌合凹部５４ａに押し込むと、嵌合凹部５４ａの開口周縁が変形して嵌合凹部５４ａ内に挿入され、その後嵌合凹部５４ａに弾性復帰して、嵌合凸部６１ａが抜け止めされて嵌合し、リンク６０ａ、６０ｂのラッチ６２を、リッド２０の外方に押し出す方向に弾性付勢する。このように、この実施形態においては、反力付与板７０ａ、７０ｂの一端がクランク５０の一端に連結され、反力付与板７０の他端がリンク６０の中間部６３に連結され、かつ、リンク６０の一端がクランク５０の一端に連結されていない状態で射出成形されているので、クランク５０、リンク６０ａ、６０ｂ、及び反力付与板７０ａ、７０ｂを一体成形でき、製造コストを低減させ組立作業性も向上させる。 When the fitting convex portion 61a is pushed into the fitting concave portion 54a, the opening peripheral edge of the fitting concave portion 54a is deformed and inserted into the fitting concave portion 54a, and then elastically returns to the fitting concave portion 54a. The portion 61a is prevented from coming off and fitted, and the latch 62 of the links 60a and 60b is elastically biased in the direction of pushing the lid 20 outward. Thus, in this embodiment, one end of the reaction force applying plates 70a and 70b is connected to one end of the crank 50, the other end of the reaction force applying plate 70 is connected to the intermediate portion 63 of the link 60, and the link Since one end of 60 is injection-molded without being connected to one end of the crank 50, the crank 50, the links 60a and 60b, and the reaction force applying plates 70a and 70b can be integrally formed, reducing the manufacturing cost and assembling work. Improves performance.

図９には、本発明のリッド開閉装置の更に他の実施形態が示されている。なお、前記実施形態と実質的に同一部分には同符号を付してその説明を省略する。 FIG. 9 shows still another embodiment of the lid opening / closing device of the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

この実施形態においては、図９に示すように、リンク６０ａ、６０ｂの一端がクランク５０の一端に連結され、かつ、反力付与板７０ａ、７０ｂの一端がクランク５０の他端に連結され、反力付与板７０ａ、７０ｂの他端がリンクの中間部６３に連結されて、リンク６０ａ、６０ｂのラッチ６２がリッド２０の外方に押し出される形状で射出成形されており、操作子３０を回転させることにより反力付与板７０ａ、７０ｂの付勢力に抗して、リンク６０ａ、６０ｂのラッチ６２をリッド２０の内側に引き込むように構成している。この実施形態においては、クランク５０、リンク６０ａ、６０ｂ、及び反力付与板７０ａ、７０ｂのそれぞれの端部が、全て連結された状態で射出成形されているので、反力付与板７０ａ、７０ｂの端部、或いは、リンク６０ａ、６０ｂの端部の連結作業が必要なく、組立作業性が向上する。 In this embodiment, as shown in FIG. 9, one end of the links 60a, 60b is connected to one end of the crank 50, and one end of the reaction force applying plates 70a, 70b is connected to the other end of the crank 50. The other ends of the force applying plates 70a and 70b are connected to the intermediate portion 63 of the link, and the latch 62 of the links 60a and 60b is injection-molded so as to be pushed out of the lid 20, and the operation element 30 is rotated. Thus, the latches 62 of the links 60 a and 60 b are configured to be pulled inside the lid 20 against the urging force of the reaction force applying plates 70 a and 70 b. In this embodiment, the crank 50, the links 60a, 60b, and the reaction force application plates 70a, 70b are all connected to each other by injection molding, so the reaction force application plates 70a, 70b There is no need to connect the end portions or the end portions of the links 60a and 60b, and the assembly workability is improved.

なお、上記実施形態においては、クランク５０の一対の連結部５４、５４のそれぞれに、リンク６０ａ、６０ｂ及び反力付与板７０ａ、７０ｂが連結されているが、リンク及び反力付与板をクランク５０の片側の連結部５４、５４にだけ、設けておいてもよい。また、上記実施形態においては、壁部１１が本発明における枠体をなしている。 In the above embodiment, the links 60a and 60b and the reaction force applying plates 70a and 70b are connected to the pair of connecting portions 54 and 54 of the crank 50, respectively. It may be provided only in the connecting portions 54, 54 on one side. Moreover, in the said embodiment, the wall part 11 has comprised the frame in this invention.

本発明は、自動車等の荷室の壁部等のリッドの開閉操作を繰り返し行っても、開口部に係合するラッチをリッドの外側へしっかりと押し出し、開口部を閉じた状態に確実にロックして、リッドの開閉操作がスムーズになされるリッド開閉装置として利用することができる。 The present invention firmly pushes the latch that engages the opening to the outside of the lid even when the opening and closing operation of the lid of the cargo compartment wall of an automobile or the like is repeatedly performed, and securely locks the opening in the closed state.
