特許文献１に記載のマット固定装置は、全体として細長い板状部材として形成され、マット等をフロアパネルやフロアパネルに固着されたパッド等の被取付部材に取付けるにおいて、マットの取付穴のある位置で被取付部材に係止し又は固定する構成ではない。従って、マットの位置ずれの防止は可能であるが、マットを被取付部材の取付位置に正確に維持し固定する機能は欠けている。特許文献２には、取付ノブ形状のクリップによって、２つのパネルを連結する構造が記載されている。特許文献２の取付ノブ形状のクリップは、一方のパネル非ロック位置において仮止めされ、次に、クリップ軸部を他方のパネルに挿入してロック位置に軸回りに所定角度（９０度）回転させてクリップを他方のパネルに固定することで一方のパネルと他方のパネルを連結する。特許文献２はマットを被取付部材の取付位置に正確に維持し固定する固定装置を記載していない。 The mat fixing device described in Patent Document 1 is formed as a long and slender plate-like member as a whole, and is used to attach a mat or the like to a member to be attached such as a floor panel or a pad fixed to the floor panel. It is not the structure which latches or fixes to a to-be-attached member. Therefore, although the mat can be prevented from being displaced, the function of accurately maintaining and fixing the mat at the mounting position of the member to be mounted is lacking. Patent Document 2 describes a structure in which two panels are connected by an attachment knob-shaped clip. The clip of the mounting knob shape of Patent Document 2 is temporarily fixed at one panel unlocked position, and then the clip shaft portion is inserted into the other panel and rotated around the axis by a predetermined angle (90 degrees) to the locked position. By fixing the clip to the other panel, one panel and the other panel are connected. Patent Document 2 does not describe a fixing device that accurately maintains and fixes the mat at the mounting position of the mounted member.

特許文献３には、フロアパネルに固定された、被取付部材としてのパッドに固定される第１クリップと、パッドに固定するマットを支持するための第２クリップと、マットに固定されるマット固定具と、第２クリップをマット固定具に連結する取付ノブとを備える、自動車のマットの固定装置が記載されている。第１クリップは、パッドを支持する固定部と、固定部を第２クリップに連結するための筒状の連結部を有し、第２クリップは、第１クリップの連結部に入れ子状に連結される筒状の連結部を有する。マットを第２クリップに連結するには、第２クリップに連結された取付ノブに、マットに固定されたマット固定具の保持部の穴を貫通させて非ロック位置からロック位置に軸回りに回転させる。マットを被取付部材であるパッドに固定するためには、パッドに固定された第１クリップの連結部に、マットを支持する第２クリップの連結部を押し込むだけでよい。これによって、マットの取付穴のある位置で被取付部材に係止し又は固定する構成であり、マットの位置ずれの防止だけでなく、マットを被取付部材の取付位置に正確に維持し固定でき、見栄えもよい。 Patent Document 3 discloses a first clip fixed to a pad as a member to be attached, fixed to a floor panel, a second clip for supporting a mat fixed to the pad, and a mat fixed to the mat. An automotive mat fixing device is described comprising a tool and a mounting knob for connecting a second clip to the mat fixing tool. The first clip has a fixing part that supports the pad and a cylindrical connecting part for connecting the fixing part to the second clip, and the second clip is connected to the connecting part of the first clip in a nested manner. A cylindrical connecting portion. To connect the mat to the second clip, the mounting knob connected to the second clip passes through the hole in the holding part of the mat fixture fixed to the mat and rotates around the axis from the unlocked position to the locked position. Let In order to fix the mat to the pad which is a member to be attached, it is only necessary to push the connecting portion of the second clip supporting the mat into the connecting portion of the first clip fixed to the pad. As a result, it is configured to be locked or fixed to the mounted member at a position where the mat has a mounting hole, not only preventing the mat from being displaced, but also accurately maintaining and fixing the mat at the mounting position of the mounted member. Good looking.

特許文献３の固定装置において、取付ノブが、頭部のつまみ部と、つまみ部から垂下する一対の係止脚とを有する形状であるので、取付ノブが強度において改良の余地がある。例えば、マットにこじりあげる力が作用したとき、それが強力な力である場合には対抗できないときがあった。また、一対の係止脚に割れを生じるおそれがあった。従って。マットをパッドに固定した後の取付ノブの保持力を向上するのが望ましく、また、取付ノブ自体の強度を高くできるのが望ましい。更に、マットを被取付部材に取付ける操作において操作完了の感覚を作業者に確実に伝達できるのが望ましい。 In the fixing device of Patent Document 3, since the mounting knob has a shape having a knob portion on the head and a pair of locking legs depending from the knob portion, the mounting knob has room for improvement in strength. For example, there is a case in which when a force that squeezes the mat is applied, it cannot be countered if it is a powerful force. Moreover, there was a possibility of causing a crack in the pair of locking legs. Therefore. It is desirable to improve the holding force of the mounting knob after the mat is fixed to the pad, and it is desirable that the strength of the mounting knob itself can be increased. Furthermore, it is desirable that the operation completion feeling can be reliably transmitted to the operator in the operation of attaching the mat to the attached member.

従って、本発明の目的は、自動車のフロアパネルやフロアパネルに固着されたパッド等の被取付部材に固定するため、自動車のマットを被取付部材の取付位置に正確に維持し固定でき、取付ノブの固定力を向上させて、マットをこじりあげる力に十分に対抗でき、取付ノブ自体の強度を向上させた、自動車のマットの固定装置を提供することにある。 Accordingly, the object of the present invention is to fix the car mat to the mounting position of the mounted member accurately in order to fix it to the mounting member such as the pad fixed to the floor panel of the vehicle or the floor panel, and the mounting knob. It is an object of the present invention to provide a mat fixing device for an automobile, which can sufficiently counter the force to lift the mat and improve the strength of the mounting knob itself.

上記目的を達成するため、本発明は、自動車のマットを被取付部材に固定するため、前記被取付部材に固定される第１クリップと、前記マットを保持するための第２クリップとを備え、前記第１クリップは、前記被取付部材に固定される固定部と、前記被取付部材に前記マットが取付けられるように前記固定部から立設して形成されて前記第２クリップに連結される筒状の連結部とを有し、前記第２クリップは、前記マットを保持するように大径に形成されたフランジと、該フランジの上面に形成された支持部と、前記フランジの下面側に形成され、前記第１クリップの連結部に入れ子状に連結される筒状の連結部とを有し、前記第１クリップの連結部と前記第２クリップの連結部とは、相互に入れ子状に連結されることによって前記第１クリップが前記第２クリップに連結されるように形成されており、更に、前記マットに固定されるマット固定具と、前記第２クリップを前記マット固定具に連結する取付ノブとを備え、前記取付ノブは、頭部のつまみ部と、該つまみ部から垂下する係止脚とを有し、前記マット固定具には、前記取付ノブが前記係止脚の軸回りにおいて一定の角度の非ロック位置にあるときには前記つまみ部が通過できるが軸回りに前記非ロック位置から所定角度のロック位置に回転させると前記つまみ部が通過できない穴を有する板状の保持部が形成されており、前記取付ノブは、前記係止脚を前記非ロック位置にある状態で前記第２クリップの前記支持部まで押込んだ後前記ロック位置に軸心回りに回転させられることによって前記係止脚の先端の係止部が前記支持部に係止するように形成され、更に、前記取付ノブは、前記つまみ部が、前記非ロック位置にある状態では前記マット固定具の前記保持部の前記穴を貫通することができるが前記ロック位置に回転させられることによって該保持部から抜け出ないように形成されており、前記第１クリップに固定された前記被取付部材に前記第２クリップ及び前記取付ノブを介して前記マット固定具に固定された前記マットが固定される、自動車のマットの固定装置であって：前記取付ノブは、前記係止脚が、前記つまみ部から垂下する剛性の棒状部と該棒状部から更に垂下する先端の前記係止部とを備え、前記係止部は、前記ロック位置への前記所定角度の軸心回りの回転によって前記第２クリップの前記支持部に係止する係止肩を提供するように前記棒状部より半径方向外側に張出す剛性の板状である、ことを特徴とする固定装置が提供される。 In order to achieve the above object, the present invention comprises a first clip fixed to the mounted member for fixing a car mat to the mounted member, and a second clip for holding the mat. The first clip is a fixed portion fixed to the attached member, and a cylinder formed standing from the fixed portion so that the mat is attached to the attached member and connected to the second clip. And the second clip is formed on a flange having a large diameter so as to hold the mat, a support formed on an upper surface of the flange, and a lower surface of the flange. And a cylindrical connecting portion that is connected to the connecting portion of the first clip in a nested manner, and the connecting portion of the first clip and the connecting portion of the second clip are connected to each other in a nested manner. The first And a mat fixing tool that is fixed to the mat, and a mounting knob that connects the second clip to the mat fixing tool. The mounting knob has a knob portion on the head and a locking leg hanging from the knob portion, and the mat fixing member has a locking angle at which the mounting knob is non-locked around an axis of the locking leg. A plate-like holding portion having a hole through which the knob portion can pass when it is in position but cannot be passed through when the knob portion is rotated from the unlocked position to a locked position at a predetermined angle around the axis, The knob is engaged with the front end of the locking leg by being rotated about the axis to the locking position after pushing the locking leg to the support portion of the second clip in the unlocked position. Stop In addition, the mounting knob can pass through the hole of the holding portion of the mat fixture in a state where the knob portion is in the unlocked position. The mat fixing tool is formed so as not to come out of the holding portion by being rotated to the lock position, and is attached to the attached member fixed to the first clip via the second clip and the attachment knob. An automobile mat fixing device in which the mat fixed to a vehicle is fixed: the mounting knob includes a rigid rod-like portion that hangs down from the knob portion, and a hanging rod that further hangs down from the rod-like portion. And a locking shoulder that locks to the support portion of the second clip by rotation around the axis of the predetermined angle to the locking position. Before There is provided a fixing device characterized by a rigid plate-like shape projecting radially outward from the recording bar-like portion.

上記のとおり、特許文献３に記載の固定装置の基本構造はそのまま有しているので、自動車のフロアパネルやフロアパネルに固着されたパッド等の被取付部材に固定するため、自動車のマットを被取付部材の取付位置に正確に維持し固定でき、また、取付ノブは、つまみ部から延びる係止脚が剛性の棒状部と剛性の板状の係止部とから形成されるので、取付ノブの固定力を向上させて、マットのこじりあげる力に十分に対抗でき、取付ノブ自体の強度も向上させることができ、非ロック位置からロック位置への回転の場合の割れを防止できる。 As described above, since the basic structure of the fixing device described in Patent Document 3 is maintained as it is, the mat of an automobile is covered with an automobile mat so as to be fixed to an attachment member such as a pad fixed to the floor panel of the automobile or the floor panel. The mounting knob can be accurately maintained and fixed at the mounting position of the mounting member, and the mounting knob has a locking leg extending from the knob portion formed of a rigid bar-shaped portion and a rigid plate-shaped locking portion. By improving the fixing force, it is possible to sufficiently counter the force that the mat is raised, the strength of the mounting knob itself can be improved, and cracking in the case of rotation from the unlocked position to the locked position can be prevented.

上記固定装置において、前記取付ノブには、前記係止脚の前記係止部に、前記棒状部の軸線の延長線上の前記板状の部分の両面から突出する錨脚形状の錨脚係止部を有し、該錨脚係止部は、前記第２クリップの前記支持部に押込まれると前記錨脚形状の部分が内方に撓んだ後に元の姿勢に復帰して前記支持部に係止するように形成されて、該取付ノブが第２クリップに連結できる。これによって、取付ノブは第２クリップに押し込むだけで非ロック位置において連結（仮止め）され、取付ノブの連結操作が容易になる。前記取付ノブの前記棒状部の側面には、半径方向外側に突出する凸部が形成されており、前記第２クリップの前記支持部には、押し込まれた前記棒状部の前記凸部を受入れて嵌合する形状の凹部であって前記係止脚が前記ロック位置への前記所定の回転によって係止脚外面の凸部に嵌合する位置に設けられた前記凹部を有し、該凹部に前記凸部が嵌合することによって該取付ノブによって第２クリップを前記マットに固定したのを感知できるとともに、その固定を維持できる。このように、ロック位置への完了を知るクリック感覚を、係止部とは異なる位置の棒状部に形成したことで、係止部の固定強度を向上させても、そのクリック感覚を損なうことがなくなり、固定操作の完了を作業者は確実に知ることができる。 In the fixing device, the attachment knob includes a hook-shaped hook-leg locking portion that protrudes from both sides of the plate-like portion on the extension line of the axis of the rod-like portion to the locking portion of the locking leg. The hook-leg locking part is returned to its original posture after the hook-shaped part is bent inward when pushed into the support part of the second clip. Formed to lock, the attachment knob can be coupled to the second clip. As a result, the attachment knob is connected (temporarily fixed) at the non-locked position simply by being pushed into the second clip, and the connection operation of the attachment knob is facilitated. A convex portion that protrudes radially outward is formed on a side surface of the rod-shaped portion of the mounting knob, and the convex portion of the rod-shaped portion that is pushed in is received by the support portion of the second clip. A recess having a shape to be fitted, wherein the locking leg is provided at a position where the locking leg is fitted to a convex portion of the locking leg outer surface by the predetermined rotation to the locking position. By fitting the convex portion, it can be sensed that the second clip is fixed to the mat by the mounting knob, and the fixing can be maintained. In this way, the click sensation to know the completion of the lock position is formed on the rod-shaped part at a position different from the engagement part, so even if the fixation strength of the engagement part is improved, the click sensation may be impaired. Thus, the operator can surely know the completion of the fixing operation.

前記第２クリップの前記支持部は、前記フランジに近い位置に形成された剛性の支持板と、該支持板から前記フランジより離れるように延び出る中空の筒状部と、該筒状部の内側を該筒状部の頂部から前記支持板に向けて延びる、一対の、相互に離間した平行な弾性支持体とから成り、前記一対の弾性支持体は、それらの間に、前記係止脚を通過できる空間を形成しており、各弾性支持体には、前記空間を通った前記棒状部の前記凸部に嵌合する前記凹部が、前記頂部から前記支持板に向けて長手方向に沿って延びる溝形状に形成されている。筒状部によって、取付ノブの係止脚は、ぐらつくことなく、第２クリップに確実に保持されて、取付ノブには、ぐらつく場合の過剰な負荷がかからなくなり、これによって、固定力が一層向上し、係止脚の割れへの抵抗も一層向上する。前記第２クリップの前記支持部の前記頂部には、前記取付ノブの前記係止脚先端の板状の前記係止部と前記錨脚係止部とを前記非ロック位置に対応する方向において受入れる形状の受入穴が形成されており、前記一対の弾性支持体の間の前記空間は、前記非ロック位置にある前記板状の前記係止部が通過でき且つ前記錨脚係止部の錨脚部分が前記溝部分をスライドしながら通過できる横断面形状である。これによって、作業者は、取付ノブを第２クリップに対して非ロック位置にある軸回り角度で第２クリップの筒状部に容易に挿入できる。 The support portion of the second clip includes a rigid support plate formed at a position close to the flange, a hollow cylindrical portion extending away from the flange from the support plate, and an inner side of the cylindrical portion Extending from the top of the cylindrical portion toward the support plate, and a pair of mutually parallel parallel elastic supports, and the pair of elastic supports includes the locking legs between them. A space that can be passed is formed, and each of the elastic supports has a concave portion that fits into the convex portion of the rod-shaped portion that passes through the space, along the longitudinal direction from the top portion toward the support plate. It is formed in an extending groove shape. Due to the cylindrical portion, the locking leg of the mounting knob is securely held by the second clip without wobbling, and the mounting knob is not subjected to excessive load in the case of wobbling, thereby further increasing the fixing force. And the resistance to cracking of the locking leg is further improved. The top portion of the support portion of the second clip receives the plate-like locking portion at the distal end of the locking leg of the mounting knob and the hook-leg locking portion in a direction corresponding to the unlocked position. A receiving hole having a shape is formed, and the space between the pair of elastic supports can pass through the plate-shaped locking portion in the unlocked position, and the hook leg of the hook leg locking portion. The portion has a cross-sectional shape that can pass through the groove portion while sliding. Thus, the operator can easily insert the attachment knob into the cylindrical portion of the second clip at an angle around the axis that is in the unlocked position with respect to the second clip.

前記取付ノブの前記つまみ部は、前記マット固定具の前記保持部を貫通した状態において作業者の指が差し込めるスペースを確保できるように平面視において細長い形状に形成されている。また、前記取付ノブの前記つまみ部は、前記マット固定具の前記保持部を貫通した状態において前記保持部からの突出高さが作業者の指で容易に触れる高さを確保できるように形成されている。前記マット固定具は、マットの取付穴の周縁を、上面から押さえるアッパーグロメットと下面から押さえるロワーグロメットとから成り、前記アッパーグロメットに、前記保持部が形成されているのが好ましい。その場合、内径と外径の差を大きくすることによって、マットの保持面積が大きくでき、それによって、マットの保持力が向上して、マットをこじりあげる力への抵抗力も向上する。 The knob portion of the mounting knob is formed in an elongated shape in a plan view so as to ensure a space where an operator's finger can be inserted in a state where it passes through the holding portion of the mat fixture. Further, the knob portion of the mounting knob is formed so that a protrusion height from the holding portion can be easily touched with an operator's finger in a state of passing through the holding portion of the mat fixture. ing. It is preferable that the mat fixture includes an upper grommet that presses the periphery of the mounting hole of the mat from the upper surface and a lower grommet that presses the periphery from the lower surface, and the holding portion is formed on the upper grommet. In that case, by increasing the difference between the inner diameter and the outer diameter, the holding area of the mat can be increased, whereby the holding power of the mat is improved, and the resistance to the force of lifting the mat is also improved.

図１には、第１クリップ１が示されている。第１クリップ１は、硬質の合成樹脂材料で一体成形される。第１クリップ１は、細長い板状アームで成る、ほぼＣ形状の固定部１５と、固定部１５の上部アーム側に円筒状に形成された連結部１７とから成る。固定部１５は、パッド５の上面と下面を側面からの挿入によって挟持するように、ほぼＣ形状に形成され、パッド５の側面から、パッド５の上下面の所定位置に形成されたガイド溝（図示せず）に沿ってスライドするだけで、パッドの上下面を挟持してパッド５に固定される。固定部１５のＣ形状の内側には、パッド５の側面からガイド溝を固定方向にスライドでき、ガイド溝の途中に形成された係止凹部６５Ａ、６５Ｂに係止して戻りを阻止する一対の弾性逆止爪１８が形成されている。固定部１５の外側には中央を長手方向に延びて固定部１５に剛性を与えるリブ１９が形成され、パッド５への挟持力を高く維持して、パッド５への固定力を強固にする。 A first clip 1 is shown in FIG. The first clip 1 is integrally formed of a hard synthetic resin material. The first clip 1 includes a substantially C-shaped fixing portion 15 formed of an elongated plate-like arm, and a connecting portion 17 formed in a cylindrical shape on the upper arm side of the fixing portion 15. The fixing portion 15 is formed in a substantially C shape so as to sandwich the upper surface and the lower surface of the pad 5 by insertion from the side surface, and guide grooves (formed at predetermined positions on the upper and lower surfaces of the pad 5 from the side surface of the pad 5). The upper and lower surfaces of the pad are clamped and fixed to the pad 5 simply by sliding along the not shown. On the inner side of the C shape of the fixing portion 15, a pair of guide grooves can be slid in the fixing direction from the side surface of the pad 5, and locked to locking recesses 65 A and 65 B formed in the middle of the guide groove to prevent return. An elastic check claw 18 is formed. A rib 19 is formed on the outer side of the fixing portion 15 to extend in the longitudinal direction in the center to give rigidity to the fixing portion 15, and maintains a high clamping force to the pad 5, thereby strengthening the fixing force to the pad 5.

連結部１７は、固定部１５の上部アームから上方に延びる円筒状に形成され、第２クリップ２の円筒状の連結部２５の内側に挿入されて、第２クリップ２に連結される。連結部１７には、第１クリップ１を第２クリップ２に連結するため、第２クリップ２の円筒状連結部２５の一対の係止肩２９に係止する一対の弾性係止片２１が設けられている。更に、弾性係止片２１は、下方側の面２２（図１（Ｆ）参照）が、第２クリップ２の強い引き抜き力で第２クリップ２の連結部の係止肩２９が乗り越えられるように、ほぼ４５度の傾斜面として形成されている。これによって、第１クリップ１に連結した第２クリップ２を強い力で引き抜くことができ、マットの清掃や交換のときに、第２クリップ２に連結されたマット６を、パッド５が固定されたフロアパネル４から取外すことができる。また、連結部１７には、その外面に一対の係止片２１に対して周方向に９０度離れた位置に、長手方向に延びる一対のリブ２３が形成されている。リブ２３は連結部１７の強度を高くし、更に、リブ２３は、第２クリップ２の円筒状連結部２５の内側に形成された一対の凹溝２８に受入れられる。凹溝２８とリブ２３との組合せによって、第２クリップ２が、第１クリップ１に連結されるときの方向を適正にして係止片２１と係止肩２９との係合を確実にして、第２クリップ２が第１クリップ１に押込まれるだけで第１クリップ１に連結するのが確保され、第１クリップ１への誤組み付けを防止できる。 The connecting portion 17 is formed in a cylindrical shape that extends upward from the upper arm of the fixing portion 15, is inserted into the cylindrical connecting portion 25 of the second clip 2, and is connected to the second clip 2. The connecting portion 17 is provided with a pair of elastic locking pieces 21 that are locked to a pair of locking shoulders 29 of the cylindrical connecting portion 25 of the second clip 2 in order to connect the first clip 1 to the second clip 2.

Furthermore, the elastic locking piece 21 has a lower surface 22 (see FIG. 1 (F)) so that the locking shoulder 29 of the connecting portion of the second clip 2 can get over by the strong pulling force of the second clip 2. It is formed as an inclined surface of approximately 45 degrees. As a result, the second clip 2 connected to the first clip 1 can be pulled out with a strong force, and the pad 5 is fixed to the mat 6 connected to the second clip 2 when the mat is cleaned or replaced. It can be removed from the floor panel 4. In addition, a pair of ribs 23 extending in the longitudinal direction are formed on the outer surface of the connecting portion 17 at positions spaced 90 degrees in the circumferential direction with respect to the pair of locking pieces 21. The rib 23 increases the strength of the connecting portion 17, and the rib 23 is received in a pair of concave grooves 28 formed inside the cylindrical connecting portion 25 of the second clip 2. By the combination of the concave groove 28 and the rib 23, the direction when the second clip 2 is connected to the first clip 1 is made appropriate and the engagement between the locking piece 21 and the locking shoulder 29 is ensured, Only when the second clip 2 is pushed into the first clip 1, it is ensured that the second clip 2 is connected to the first clip 1, and erroneous assembly to the first clip 1 can be prevented.

図２には、第２クリップ２が示されている。第２クリップ２は、第１クリップ１と同様に硬質の合成樹脂材料で一体成形される。第２クリップ２は、第１クリップ１に連結される連結部２５と、連結部２５の上端に形成されて、マット６を保持するとともにインシュレータ１１（図１１等）等を押圧するように張り出す大径のフランジ２６と、フランジ２６の上方に形成されて、取付ノブ３を介してマット６に取付けられてマット６を支持する支持部２７とを有する。連結部２５は、第１クリップ１の連結部１７を受入れる中空の円筒形状に形成され、連結部２５には、第１クリップ１の連結部１７の弾性係止片２１に係止するための係止肩２９（図２（Ｅ）参照）を形成する穴３０が直径方向に対向して一対形成されている。また、連結部２５の内側には、第１クリップ１の連結部１７のリブ２３を受入れる長手方向方向に延びる凹溝２８が、一対形成されている。フランジ２６は、マット６をその下面側から保持し、また、インシュレータ１１を下方に押圧して保持できるように大径の円板形に形成される。 FIG. 2 shows the second clip 2. Similar to the first clip 1, the second clip 2 is integrally formed of a hard synthetic resin material. The second clip 2 is formed at a connecting portion 25 connected to the first clip 1 and an upper end of the connecting portion 25, and holds the mat 6 and protrudes so as to press the insulator 11 (FIG. 11 and the like). It has a large-diameter flange 26 and a support portion 27 that is formed above the flange 26 and is attached to the mat 6 via the attachment knob 3 to support the mat 6. The connecting portion 25 is formed in a hollow cylindrical shape that receives the connecting portion 17 of the first clip 1, and the connecting portion 25 is engaged with the elastic locking piece 21 of the connecting portion 17 of the first clip 1. A pair of holes 30 that form the shoulders 29 (see FIG. 2E) are formed opposite to each other in the diametrical direction. A pair of concave grooves 28 extending in the longitudinal direction for receiving the ribs 23 of the connecting portion 17 of the first clip 1 are formed inside the connecting portion 25. The flange 26 is formed in a large-diameter disk shape so as to hold the mat 6 from the lower surface side and press and hold the insulator 11 downward.

支持部２７は、取付ノブ３に連結されて、マット６を第２クリップ２のフランジ２６に支持させる部分である。マット６は、アッパーグロメット７とロワーグロメット９で成るマット固定具１０によって挟持されて、柔軟なマット６に保持のための剛性が付与されている。支持部２７は、マット固定具１０が固定されたマット６の部分を、取付ノブ３を用いて支持する。支持部２７は、取付ノブ３の係止脚５２を受入れて、係止脚５２の係止部５６に係止する、ほぼ楕円形の、伏せた容器形状に形成されている。支持部２７は、特許文献３の支持部より高く形成されて取付ノブ３の係止部５４を、その長さ全体を安定して支持する。更に、支持部２７は、取付ノブ３の係止脚５２の先端の係止部５６の係止肩が係止する、フランジ２６に近い側の位置に形成された剛性の支持板３１（図２の（Ａ）、（Ｅ）及び（Ｆ））と、支持板３１から上方（すなわちフランジ２６より離れる方向）の頂部３３に延び出る中空の筒状部３４と、筒状部３４の内側を筒状部３４の頂部３３から支持板３１に向けて延びる、相互に離間した平行な一対の弾性支持体３２とを有する。一対の弾性支持体３２は、それらの間に、係止脚を通過できる空間を形成しており、各弾性支持体３２には、その空間を通った係止脚５２の棒状部の凸部に嵌合する凹部となる溝３５が、頂部３３から支持板３１に向けて長手方向に沿って延びている。 The support portion 27 is a portion that is connected to the attachment knob 3 and supports the mat 6 to the flange 26 of the second clip 2. The mat 6 is sandwiched by a mat fixture 10 including an upper grommet 7 and a lower grommet 9, and the flexible mat 6 is given rigidity for holding. The support portion 27 supports the portion of the mat 6 to which the mat fixture 10 is fixed using the attachment knob 3. The support portion 27 is formed in a substantially oval, obstructed container shape that receives the locking leg 52 of the mounting knob 3 and locks it to the locking portion 56 of the locking leg 52. The support portion 27 is formed higher than the support portion of Patent Document 3, and stably supports the locking portion 54 of the mounting knob 3 over its entire length. Further, the support portion 27 is a rigid support plate 31 (see FIG. 2) formed at a position near the flange 26 where the engagement shoulder of the engagement portion 56 at the tip of the engagement leg 52 of the attachment knob 3 is engaged. (A), (E) and (F)), a hollow cylindrical portion 34 extending from the support plate 31 to the top 33 (ie, away from the flange 26), and the inside of the cylindrical portion 34 is a cylinder. And a pair of parallel elastic supports 32 extending from the top 33 of the shaped portion 34 toward the support plate 31 and spaced apart from each other. The pair of elastic supports 32 forms a space between them so as to allow the passage of the locking legs. Each elastic support 32 has a protruding portion of the rod-like portion of the locking leg 52 that passes through the space. A groove 35 serving as a recess to be fitted extends along the longitudinal direction from the top 33 toward the support plate 31.

支持部２７の頂部３３及び支持板３１には、取付ノブ３の係止脚５２を受入れる穴３６が形成されている。穴３６は、取付ノブ３の係止脚の先端の板状の係止部５６を、非ロック位置の姿勢で受入れるように長穴に形成され、更に、穴３６の中央部分は、係止部５６に形成された錨脚係止部の錨脚部分をやや撓んだ状態で受入れるように長穴に直交する方向に拡げて形成されている。穴３６には、取付ノブ３の係止脚５２が挿入される。係止脚５２が頂部３３の穴３６及び支持板３１の穴３６を通って挿入されると、係止脚５２は非ロック位置にある角度で支持２７に挿入されて、係止脚５２の錨脚係止部の錨脚部分が、支持板３１に係止して、取付ノブ３が非ロック位置にある状態で第２クリップ２に連結される。次に、取付ノブ３が軸心回りに９０度回転させられると、ロック位置になり、取付ノブ３の係止脚５２の係止部５６にある係止肩が支持板３１に係止して、取付ノブ３と第２クリップ２との連結がロックされる。また、係止脚５２の棒状部に形成された凸部５９が、弾性支持体３２の溝３５に嵌合して係止脚５２がその位置に留まり、取付ノブ３の姿勢を９０度回転した、ロック位置に維持する。取付ノブ３の係止脚５２の棒状部の凸部と凹部を形成する溝３５との嵌合は、取付ノブ３を操作する作業者の手にその感触（クリック）を与えて、９０度の回転の終了すなわちロック位置への回転の完了を報せる。支持部２７のフランジ２６の上面は、マット６を支持するときロワーグロメット９を支持する面となる。なお、取付ノブ３を受入れる穴３６は、取付ノブ３の向きを規制しているので、フランジ２６の表面には矢印マーク３７が形成されて、作業者にその向きを表示し、作業を助けている。矢印マーク３７は、また、第２クリップ２の連結部２５を第１クリップ１の連結部１７に押込むときの第２クリップ２の向きも表示している。 A hole 36 for receiving the locking leg 52 of the mounting knob 3 is formed in the top 33 of the support 27 and the support plate 31. The hole 36 is formed as a long hole so as to receive the plate-like locking portion 56 at the tip of the locking leg of the mounting knob 3 in the non-locking position, and the central portion of the hole 36 has a locking portion. It is formed to be expanded in a direction perpendicular to the elongated hole so as to receive the leg part of the leg locking part formed in 56 in a slightly bent state. The locking leg 52 of the mounting knob 3 is inserted into the hole 36. When the locking leg 52 is inserted through the hole 36 of the top 33 and the hole 36 of the support plate 31, the locking leg 52 is inserted into the support 27 at an angle at the unlocked position, The leg portion of the leg engaging portion is engaged with the support plate 31 and connected to the second clip 2 in a state where the attachment knob 3 is in the unlocked position. Next, when the mounting knob 3 is rotated 90 degrees around the axis, the locking position is reached, and the locking shoulder of the locking portion 56 of the locking leg 52 of the mounting knob 3 is locked to the support plate 31. The connection between the mounting knob 3 and the second clip 2 is locked. Further, the convex portion 59 formed on the rod-shaped portion of the locking leg 52 fits into the groove 35 of the elastic support 32 so that the locking leg 52 stays in that position, and the attitude of the mounting knob 3 is rotated by 90 degrees. Keep in the locked position. The fitting of the convex portion of the rod-like portion of the locking leg 52 of the mounting knob 3 and the groove 35 forming the concave portion gives the feel (click) to the hand of the operator who operates the mounting knob 3, and is 90 degrees. The end of rotation, that is, completion of rotation to the locked position can be reported. The upper surface of the flange 26 of the support portion 27 is a surface that supports the lower grommet 9 when the mat 6 is supported. Since the hole 36 for receiving the mounting knob 3 regulates the direction of the mounting knob 3, an arrow mark 37 is formed on the surface of the flange 26 to display the direction to the operator and help the work. Yes. The arrow mark 37 also indicates the direction of the second clip 2 when the connecting portion 25 of the second clip 2 is pushed into the connecting portion 17 of the first clip 1.

図３及び図４を参照して、アッパーグロメット７とロワーグロメット９とから構成されるマット固定具１０を説明する。アッパーグロメット７及びロワーグロメット９は、それぞれ、合成樹脂材料で一体成形される。合成樹脂材料は、硬質の材料であっても、弾性係数が低く且つ塑性変形し易い樹脂材料であってもよい。アッパーグロメット７とロワーグロメット９は、図９に図示のように、マット６を上下面から挟持して、マット６に固定され、柔軟なマット６、とりわけ、マット６の穴の周囲を補強して、他の部材への取付けを強固にするとともに、穴周囲からの破損を防止する。 With reference to FIG.3 and FIG.4, the mat fixing tool 10 comprised from the upper grommet 7 and the lower grommet 9 is demonstrated. Each of the upper grommet 7 and the lower grommet 9 is integrally formed of a synthetic resin material. The synthetic resin material may be a hard material or a resin material having a low elastic modulus and easily plastically deformed. As shown in FIG. 9, the upper grommet 7 and the lower grommet 9 are fixed to the mat 6 by sandwiching the mat 6 from the upper and lower surfaces, and reinforce the periphery of the hole of the flexible mat 6, particularly the mat 6. In addition to strengthening attachment to other members, damage from around the hole is prevented.

図３において、アッパーグロメット７は、ロワーグロメット９の外筒部に挿入される内側の筒としての、両端が開口した内筒部３９と、内筒部３９の一端の外周に形成されてマットの一方の面に接するフランジ４０と、内筒部３９の内側の中間高さ位置に内側に張り出した板状の保持部４１とを有する。内筒部３９の軸線方向の長さは、マット６の厚さ程度に短くされる。内筒部３９の外周面には、アッパーグロメット７とロワーグロメット９とを相互に連結するため、複数段の係止爪４２が設けられている。係止爪４２の形状は、挿入は容易であるが抜き出しには抵抗する形状になっている。 In FIG. 3, the upper grommet 7 is formed on the outer periphery of one end of the inner cylinder portion 39 and an inner cylinder portion 39 having both ends opened as inner cylinders inserted into the outer cylinder portion of the lower grommet 9. It has a flange 40 in contact with one surface and a plate-like holding portion 41 projecting inward at an intermediate height position inside the inner cylinder portion 39. The length of the inner cylinder portion 39 in the axial direction is shortened to about the thickness of the mat 6. A plurality of stages of locking claws 42 are provided on the outer peripheral surface of the inner cylindrical portion 39 in order to connect the upper grommet 7 and the lower grommet 9 to each other. The shape of the locking claw 42 is a shape that can be easily inserted but resists extraction.

内筒部３９は中空に形成され、内筒部３９の中間高さ位置には、板状の保持部４１が形成されている。保持部４１には、取付ノブ３の係止脚５２が非ロック位置の回転位置で貫通する楕円の穴４３が形成されている。フランジ４０は、マット６の取付穴周縁の上面に当接する一定の大きさの円板に形成されている。フランジ４０の下面には、アッパーグロメット７とロワーグロメット９を相互に連結した状態でマット６のおもて面に食い込む突起４４が複数個形成されており、アッパーグロメット７の回転を阻止する。 The inner cylinder part 39 is formed hollow, and a plate-like holding part 41 is formed at an intermediate height position of the inner cylinder part 39. The holding portion 41 is formed with an elliptical hole 43 through which the locking leg 52 of the mounting knob 3 penetrates at the rotational position of the unlocked position. The flange 40 is formed as a disk of a certain size that contacts the upper surface of the periphery of the mounting hole of the mat 6. A plurality of protrusions 44 are formed on the lower surface of the flange 40 so as to bite into the front surface of the mat 6 in a state where the upper grommet 7 and the lower grommet 9 are connected to each other, thereby preventing the rotation of the upper grommet 7.

図４において、ロワーグロメット９は、マット６の取付穴に挿入されるとともに、アッパーグロメット７の内筒部３９を受入れ外側の筒となるように、中空の外筒部４６と、外筒部の一端の外周に形成されてマットの下方の面に接するフランジ４７とを有する。外筒部４６の軸線方向長さは、アッパーグロメット７の内筒部３９を安定して受入れることができれば短いほうが好ましい。外筒部４６の外径は、マット６の取付穴に挿入できるように形成され、内径は、アッパーグロメット内筒部３９が挿入し易く且つ挿入後がたつかない大きさに形成されている。外筒部４６の内側のフランジ４７に隣接する部分には、アッパーグロメット７とロワーグロメット９を相互に連結するため、複数の弾性係止爪４８が設けられている。各係止爪４８は、アッパーグロメット７の内筒部３９の係止爪４２に係止する。各係止爪４８は、内筒部３９の挿入は許すが、抜き出し方向には係止爪４２への係止によって阻止するように弾性をもって撓む形状に形成されている。フランジ４７は、マットの取付穴の周縁の、アッパーグロメット７のフランジ４０と反対側のマット面に当接する一定の大きさの円板に形成されている。フランジ４７の上面には、マット６に食い込むように複数の突起４９が三角形状に突出して周方向に間隔をおいて形成されている。突起４９はマットに食い込むのでマットへの保持力が向上する。 In FIG. 4, the lower grommet 9 is inserted into the mounting hole of the mat 6 and receives the inner cylinder part 39 of the upper grommet 7 so as to become an outer cylinder, and a hollow outer cylinder part 46 and an outer cylinder part And a flange 47 formed on the outer periphery of one end and in contact with the lower surface of the mat. The axial direction length of the outer cylinder part 46 is preferably shorter if the inner cylinder part 39 of the upper grommet 7 can be stably received. An outer diameter of the outer cylinder portion 46 is formed so that it can be inserted into the mounting hole of the mat 6, and an inner diameter is formed such that the upper grommet inner cylinder portion 39 can be easily inserted and does not rattle after insertion. A plurality of elastic locking claws 48 are provided in a portion adjacent to the flange 47 on the inner side of the outer cylindrical portion 46 in order to connect the upper grommet 7 and the lower grommet 9 to each other. Each locking claw 48 is locked to the locking claw 42 of the inner cylindrical portion 39 of the upper grommet 7. Each locking claw 48 allows the insertion of the inner cylinder portion 39, but is formed in a shape that is elastically bent so as to be blocked by locking to the locking claw 42 in the extraction direction. The flange 47 is formed as a disk of a certain size that comes into contact with the mat surface on the side opposite to the flange 40 of the upper grommet 7 at the periphery of the mat mounting hole. On the upper surface of the flange 47, a plurality of protrusions 49 project in a triangular shape so as to bite into the mat 6 and are formed at intervals in the circumferential direction. Since the protrusion 49 bites into the mat, the holding force to the mat is improved.

なお、アッパーグロメット７の内筒部３９の外形とロワーグロメット９の外筒部４６の外形とは、円筒形状であってもよいが、図３（Ｄ）及び図４（Ｂ）に図示のように、内筒部３９が外筒部４６にほぼぴたりと収容できるような長円に形成するのが好ましく、両グロメット７、９の連結において回転方向における向き（角度）を規制すことができる。これによって、アッパーグロメット７の係止爪４２とロワーグロメット９の係止爪４８の係合を確実にすることができる。なお、アッパーグロメット７及びロワーグロメット９の内径と外径の差（図１１のＷ）を大きくすることによって、マット６の保持面積が大きくできる。それによって、マット６の保持力が向上して、マット６をこじりあげる力への抵抗力も向上する。 The outer shape of the inner cylindrical portion 39 of the upper grommet 7 and the outer shape of the outer cylindrical portion 46 of the lower grommet 9 may be cylindrical, as shown in FIGS. 3D and 4B. In addition, it is preferable that the inner cylinder portion 39 is formed in an oval shape so that it can be accommodated almost perfectly in the outer cylinder portion 46, and the direction (angle) in the rotation direction can be regulated in the connection of both grommets 7 and 9. Thereby, the engagement between the locking claw 42 of the upper grommet 7 and the locking claw 48 of the lower grommet 9 can be ensured. The holding area of the mat 6 can be increased by increasing the difference between the inner diameter and the outer diameter of the upper grommet 7 and the lower grommet 9 (W in FIG. 11). As a result, the holding force of the mat 6 is improved, and the resistance to the force of picking up the mat 6 is also improved.

図５を参照して取付ノブ３を説明する。取付ノブ３は硬質の合成樹脂材料で一体成形される。取付ノブ３は、アッパーグロメット７とロワーグロメット９で挟持されたマット６を第２クリップ２に取付けるのに用いられる。取付ノブ３は、上部の剛体のつまみ部５１と、つまみ部５１から下方に垂下する剛体の係止脚５２を有する。つまみ部５１は、図１０〜図１１に図示のように、全体が、アッパーグロメット７の内筒部３９及びフランジ４０の内側に収まる大きさに形成されている。つまみ部５１は、上部が、作業者が指等でつかんで操作できる形状に形成され、下面側は、マット６を挟持したマット固定具１０のアッパーグロメット７の保持部４１に当接するフランジとして形成されており、更に、下面側には軸心回りに円形状に下方に出っ張るストッパ５３が形成されている。ストッパ５３は、第２クリップ２の支持部２７の頂部３３の穴３６の中央部分の周囲に形成された、浅い円形凹部５４（図２（Ｂ）、（Ｊ）を参照されたい）に収容されて、取付ノブ３がそれ以上第２クリップ２の支持部２７の中に沈むのを阻止（ストップ）するともに、取付ノブ３の軸心回りの回転を滑らかにガイドする。 The attachment knob 3 will be described with reference to FIG. The mounting knob 3 is integrally formed of a hard synthetic resin material. The attachment knob 3 is used to attach the mat 6 sandwiched between the upper grommet 7 and the lower grommet 9 to the second clip 2. The attachment knob 3 has an upper rigid knob 51 and a rigid locking leg 52 depending downward from the knob 51. As shown in FIGS. 10 to 11, the knob portion 51 is formed in a size that fits inside the inner cylinder portion 39 and the flange 40 of the upper grommet 7. The upper part of the knob part 51 is formed in a shape that can be operated by a worker with a finger or the like, and the lower surface side is formed as a flange that comes into contact with the holding part 41 of the upper grommet 7 of the mat fixture 10 holding the mat 6. Furthermore, a stopper 53 that protrudes downward in a circular shape around the axis is formed on the lower surface side. The stopper 53 is accommodated in a shallow circular recess 54 (see FIGS. 2B and 2J) formed around the central portion of the hole 36 in the top 33 of the support portion 27 of the second clip 2. Thus, the mounting knob 3 is prevented (stopped) from further sinking into the support portion 27 of the second clip 2, and the rotation of the mounting knob 3 around the axis is smoothly guided.

取付ノブ３の係止脚５２は、マット６を挟持したアッパーグロメット７とロワーグロメット９を貫通し、係止脚５２の先端が、第２クリップ２の頂部３３の穴３６と、筒状部３４の中空部分と、支持板３１の穴３６とを通って、支持板３１の下面側に係止するように延びる。係止脚５２は、つまみ部５１から垂下する剛性の棒状部５５と、棒状部５５から更に垂下する先端の係止部５６とから成る。係止部５２は、非ロック位置からロック位置への所定角度（９０度）の軸心回りの回転によって第２クリップ２の支持部２７の支持板３１の下面に係止する係止肩を提供するように棒状部５５より半径方向外側に張出す剛性の板状である。このように、取付ノブ３は、つまみ部５１から延びる係止脚５２が剛性の棒状部５５と剛性の板状の係止部５６とから形成されるので、取付ノブ３の固定力を向上させて、マット６から伝わる、こじりあげる力に十分に対抗でき、更に、取付ノブ３自体の強度も向上させることができ、従って、取付ノブ３を非ロック位置からロック位置へ軸回りに回転させる場合においても、係止脚５２が割れることを防止できる。 The locking leg 52 of the mounting knob 3 passes through the upper grommet 7 and the lower grommet 9 sandwiching the mat 6, and the tip of the locking leg 52 has a hole 36 in the top 33 of the second clip 2 and the cylindrical part 34. And extends through the hole 36 of the support plate 31 so as to be engaged with the lower surface side of the support plate 31. The locking leg 52 includes a rigid rod-shaped portion 55 that hangs down from the knob portion 51, and a locking portion 56 at the tip that further hangs down from the rod-shaped portion 55. The locking portion 52 provides a locking shoulder that locks to the lower surface of the support plate 31 of the support portion 27 of the second clip 2 by rotating around a shaft center of a predetermined angle (90 degrees) from the unlocked position to the locked position. Thus, it is a rigid plate shape projecting outward in the radial direction from the rod-like portion 55. As described above, the mounting knob 3 has the locking leg 52 extending from the knob portion 51 formed of the rigid rod-shaped portion 55 and the rigid plate-shaped locking portion 56, thereby improving the fixing force of the mounting knob 3. Thus, the force transmitted from the mat 6 can be sufficiently resisted, and the strength of the mounting knob 3 itself can be improved. Therefore, when the mounting knob 3 is rotated from the unlocked position to the locked position around the axis. In this case, the locking leg 52 can be prevented from cracking.

取付ノブ３には、係止脚５２の係止部５６に、棒状部５５の軸線の延長線上の板状の部分の両面から側方に突出する錨脚形状の錨脚係止部５７を有する。錨脚係止部５７は、第２クリップ２の支持部２７の筒状部３４及び支持板３１に押込まれると錨脚形状の部分５７が内方に撓んだ後に元の姿勢に復帰して支持部２７の支持板３１の下面に係止するように形成されて、取付ノブ３が第２クリップ２に連結できる。これによって、取付ノブ３は第２クリップ２に押し込むだけで非ロック位置において連結されて仮止めされ、取付ノブ３の連結操作が容易になる。 The mounting knob 3 has a hook-shaped hook leg locking portion 57 protruding laterally from both sides of a plate-like portion on the extension line of the axis of the rod-like portion 55 on the locking portion 56 of the locking leg 52. . When the hook-leg locking portion 57 is pushed into the cylindrical portion 34 and the support plate 31 of the support portion 27 of the second clip 2, the hook-leg-shaped portion 57 returns to its original posture after bending inward. Thus, the attachment knob 3 can be connected to the second clip 2 so as to be engaged with the lower surface of the support plate 31 of the support portion 27. As a result, the attachment knob 3 is simply pushed into the second clip 2 and is connected and temporarily fixed in the unlocked position, and the connection operation of the attachment knob 3 is facilitated.

取付ノブ３の棒状部５５の側面には、半径方向外側に突出する凸部５８が形成されている。凸部５８は、棒状部５５の直径方向に対応する位置に一対形成されている。第２クリップ２の支持部２７の筒状部３４には、押し込まれた棒状部５５の凸部５８を受入れて嵌合する形状の凹部を形成する溝３５が形成されている。係止脚５２が非ロック位置からロック位置への所定（９０度）の回転によって、係止脚５２の棒状部５６の外面の凸部５８が、溝３５で成る凹部に嵌合する。凹部（溝３５）に凸部５８が嵌合することによって、取付ノブ３によって第２クリップ２がマット６に固定されたのを感知できるとともに、その固定を維持できる。このように、ロック位置への完了を知るクリック感覚を、係止部５６とは異なる位置の棒状部５５に形成したことによって、係止部５６の固定強度を向上させたとしても、そのクリック感覚を損なうことがなくなり、固定操作の完了を作業者は確実に知ることができる。 On the side surface of the rod-like portion 55 of the mounting knob 3, a convex portion 58 protruding outward in the radial direction is formed. A pair of convex portions 58 are formed at positions corresponding to the diameter direction of the rod-shaped portion 55. The cylindrical portion 34 of the support portion 27 of the second clip 2 is formed with a groove 35 that forms a recess having a shape that receives and fits the protrusion 58 of the pressed rod-like portion 55. The protrusion 58 on the outer surface of the rod-like portion 56 of the locking leg 52 is fitted into the recess formed by the groove 35 by the rotation (90 degrees) of the locking leg 52 from the non-locking position to the locking position. By fitting the convex portion 58 into the concave portion (groove 35), it can be sensed that the second clip 2 is fixed to the mat 6 by the mounting knob 3, and the fixation can be maintained. Thus, even if the fixation strength of the locking portion 56 is improved by forming the click feeling to know the completion of the locking position in the rod-like portion 55 at a position different from the locking portion 56, the click feeling is improved. Thus, the operator can surely know the completion of the fixing operation.

第２クリップ２において、フランジ２６に近い位置に形成された剛性の支持板３１と、支持板３１から延び出る筒状部３４と、筒状部３４の内側を頂部３３から支持板３１に向けて延びる、一対の、相互に離間した平行な弾性支持体３２とが形成されており、このｐ部分に挿入される取付ノブ３の係止脚５２は、ぐらつくことなく、第２クリップ２に確実に保持される。従って、取付ノブ３には、ぐらつく場合の過剰な負荷がかからなくなり、取付ノブ３が第２クリップ２をマット６に固定する力が一層向上し、係止脚５２の割れへの抵抗も一層向上する。 In the second clip 2, a rigid support plate 31 formed at a position close to the flange 26, a cylindrical portion 34 extending from the support plate 31, and an inner side of the cylindrical portion 34 from the top portion 33 toward the support plate 31. A pair of parallel elastic supports 32 that are spaced apart from each other are formed, and the locking leg 52 of the mounting knob 3 inserted into the p portion is securely attached to the second clip 2 without wobbling. Retained. Accordingly, the mounting knob 3 is not subjected to excessive load in the case of wobbling, the force with which the mounting knob 3 fixes the second clip 2 to the mat 6 is further improved, and the resistance to the cracking of the locking leg 52 is further increased. improves.

なお、第２クリップ２の支持部２７の頂部３３には、取付ノブ３の係止脚５２の先端の板状の係止部５６と錨脚係止部５７とを非ロック位置に対応する方向において受入れる形状の受入穴３６が形成されており、一対の弾性支持体３２の間の空間は、非ロック位置にある板状の係止部５６が通過でき且つ錨脚係止部５７の錨脚部分が溝部分をスライドしながら通過できる横断面形状である。これによって、作業者は、取付ノブ３を、第２クリップ２に対して非ロック位置にある軸回り角度の姿勢で、第２クリップ２の筒状部３４に容易に挿入できる。 The top 33 of the support portion 27 of the second clip 2 has a plate-like locking portion 56 at the tip of the locking leg 52 of the mounting knob 3 and a hook locking portion 57 in a direction corresponding to the unlocked position. In the space between the pair of elastic supports 32, the plate-like locking portion 56 in the unlocked position can pass through the space between the pair of elastic supports 32, and the heel leg of the heel leg locking portion 57. The portion has a cross-sectional shape that can pass through the groove portion while sliding. Thus, the operator can easily insert the attachment knob 3 into the cylindrical portion 34 of the second clip 2 in an attitude around the axis that is in the unlocked position with respect to the second clip 2.

取付ノブ３のつまみ部５１は、マット固定具１０のアッパーグロメット７の保持部４１を貫通した状態において作業者の指が差し込めるスペースを確保できるように平面視（図５（Ａ）、（Ｄ）、（Ｅ））において細長い形状に形成されている。また、取付ノブ３のつまみ部５１は、アッパーグロメット７の保持部４１を貫通した状態において保持部４１からの突出高さが作業者の指で容易に触れる高さ（図５（Ｅ）、（Ｆ））を確保できるように形成されている。 The knob 51 of the mounting knob 3 is viewed in plan view so as to secure a space for inserting the operator's finger in a state of passing through the holding part 41 of the upper grommet 7 of the mat fixture 10 (FIGS. 5A and 5D). ) And (E)). Further, the knob 51 of the mounting knob 3 has a height at which the protruding height from the holding portion 41 is easily touched by the operator's finger in a state where the holding portion 41 of the upper grommet 7 is penetrated (FIG. 5 (E), ( F)) can be secured.

図６〜図８を参照して、取付ノブ３と第２クリップ２との連結関係を説明する。図６の（Ａ）に図示のように、取付ノブ３の先端の係止部５２が、第２クリップ２の支持部２７の頂部３３の穴３６に、係止脚５２の先端の係止部５６が通過するように配置される。この配置が、取付ノブ３の係止脚５２の軸回り位置を非ロック位置にする。図６（Ａ）の鎖線に示すように、非ロック位置の姿勢にある取付ノブ３を第２クリップ２の支持部２７の穴３６に挿入する。この挿入によって、図６の（Ｂ）に図示のように、取付ノブ３は非ロック位置にある状態で第２クリップ２に連結される。図７は、この非ロック位置にある取付ノブ３が第２クリップ２に連結された状態を示している。図７の（Ｂ）に示すように、取付ノブ３の係止脚５２が第２クリップ２の支持部２７に挿入されると、係止脚５２の錨脚係止部５７が、筒状部３４及び支持板３１において内方に撓んだ後に元の姿勢に復帰して、支持部２７の支持板３１の下面に係止する。このように、取付ノブ３は第２クリップ２に押し込むだけで非ロック位置において連結されて仮止めされ、これによって、取付ノブ３が第２クリップ２に連結できる。取付ノブ３の仮止め連結操作は極めて容易である。この仮止め連結状態が、第２クリップ２及び取付ノブ３の納品荷姿となり、遠隔地にある自動車の生産ラインに送られる。その場合、取付ノブ３が第２クリップ２から分離しないので、取扱い及び管理が確実に且つ容易になる。なお、図７（Ｃ）及び（Ｄ）に図示のように、取付ノブ３が非ロック位置にあるときには、係止脚５２の係止部５６は支持板３１には係止せず、また、棒状部５５の凸部５８は弾性支持体３２の溝３５（凹部）には嵌合していない。 The connection relationship between the attachment knob 3 and the second clip 2 will be described with reference to FIGS. As shown in FIG. 6A, the locking portion 52 at the tip of the mounting knob 3 is inserted into the hole 36 in the top 33 of the support portion 27 of the second clip 2, and the locking portion at the tip of the locking leg 52. 56 is arranged to pass. This arrangement makes the position around the axis of the locking leg 52 of the mounting knob 3 an unlocked position. As shown by the chain line in FIG. 6A, the attachment knob 3 in the unlocked position is inserted into the hole 36 of the support portion 27 of the second clip 2. By this insertion, as shown in FIG. 6B, the attachment knob 3 is connected to the second clip 2 in the unlocked position. FIG. 7 shows a state in which the attachment knob 3 in the unlocked position is connected to the second clip 2. As shown in FIG. 7B, when the locking leg 52 of the mounting knob 3 is inserted into the support portion 27 of the second clip 2, the hooked leg locking portion 57 of the locking leg 52 is After being bent inward at 34 and the support plate 31, it returns to its original posture and engages with the lower surface of the support plate 31 of the support portion 27. In this way, the attachment knob 3 can be coupled to the second clip 2 by being pushed into the second clip 2 and temporarily fixed thereto, whereby the attachment knob 3 can be coupled to the second clip 2. The temporary fixing connection operation of the mounting knob 3 is extremely easy. This temporarily fixed connection state becomes the delivery form of the second clip 2 and the mounting knob 3 and is sent to the automobile production line at a remote place. In that case, since the attachment knob 3 is not separated from the second clip 2, handling and management are surely and easily performed. As shown in FIGS. 7C and 7D, when the mounting knob 3 is in the unlocked position, the locking portion 56 of the locking leg 52 is not locked to the support plate 31 and is also bar-shaped. The convex portion 58 of the portion 55 is not fitted in the groove 35 (concave portion) of the elastic support body 32.

図８においては、取付ノブ３が、非ロック位置からロック位置に係止脚５２の軸回りに９０度回転される。図８（Ａ）〜（Ｃ）では、取付ノブ３が、非ロック位置から軸回りに４５度回転された状態にある。図８（Ｄ）〜（Ｇ）では、取付ノブ３は、更に４５度回転されて、９０度回転したロック位置にある。取付ノブ３は、つまみ部５１が作業者の指でつままれて軸回りに回転させられる。図８（Ａ）〜（Ｃ）において、取付ノブ３が４５度軸回りに回転された位置にある。この状態では、棒状部５５の凸部５８は、弾性支持体３２の凹部（溝３５）にはまだ嵌合しない。図８（Ｄ）〜（Ｇ）では、作業者は、更に、取付ノブ３を軸回りに４５度回転してロック位置にする。この状態では、図８（Ｅ）に図示のように、係止脚５２の先端の係止部５６の側方に張出した部分が支持板３１の裏面に大きな面積で係合する。従って、非ロック位置の仮止め連結から本止め連結になり、取付ノブ３は第２クリップ２に堅く連結される。取付ノブ３の固定力は向上し、マット６から伝わる、こじりあげる力に対して確実に対抗できる。取付ノブ３の棒状部５５の側面の凸部５８は、第２クリップ２の支持部２７の筒状部３４の弾性支持体３２の凹部（溝３５）に嵌合（図８の（Ｇ）参照）して、クリック感覚をつまみ部５１を操作している作業者の指に伝える。これによって、作業者は取付ノブ３が第２クリップ２に本止め連結されたのを感知できるとともに、その本止め連結が維持される。このように、ロック位置への完了を知るクリック感覚を、係止部５６とは異なる位置の棒状部５５に形成したことによって、係止部５６の固定強度を向上させ、更に、そのクリック感覚を損なうことがなくなり、ロック位置への操作の完了を作業者は確実に知ることができる。 In FIG. 8, the mounting knob 3 is rotated 90 degrees around the axis of the locking leg 52 from the unlocked position to the locked position. 8A to 8C, the attachment knob 3 is rotated 45 degrees around the axis from the unlocked position. 8D to 8G, the attachment knob 3 is further rotated 45 degrees and is in the locked position rotated 90 degrees. The attachment knob 3 is rotated about its axis while the knob 51 is pinched by the operator's finger. 8A to 8C, the attachment knob 3 is at a position rotated about a 45-degree axis. In this state, the convex portion 58 of the rod-like portion 55 is not yet fitted into the concave portion (groove 35) of the elastic support body 32. In FIGS. 8D to 8G, the operator further rotates the attachment knob 3 45 degrees around the axis to the locked position. In this state, as shown in FIG. 8 (E), the portion of the end of the locking leg 52 that protrudes to the side of the locking portion 56 engages with the back surface of the support plate 31 with a large area. Accordingly, the temporary locking connection in the unlocked position is changed to the final locking connection, and the attachment knob 3 is firmly connected to the second clip 2. The fixing force of the mounting knob 3 is improved, and it is possible to surely counter the force that is transmitted from the mat 6 and that is squeezed. The convex portion 58 on the side surface of the rod-like portion 55 of the mounting knob 3 is fitted into the concave portion (groove 35) of the elastic support body 32 of the cylindrical portion 34 of the support portion 27 of the second clip 2 (see FIG. 8G). Then, the sense of clicking is transmitted to the finger of the operator who is operating the knob 51. Thus, the operator can sense that the attachment knob 3 is permanently connected to the second clip 2, and the permanent connection is maintained. Thus, by forming a click sensation to know the completion of the lock position in the rod-shaped portion 55 at a position different from the engagement portion 56, the fixing strength of the engagement portion 56 is improved, and the click sensation is further improved. The operator can surely know the completion of the operation to the lock position.

図９（Ａ）に示すように、アッパーグロメット７が、マット６の取付穴６１の上方に配置され、ロワーグロメット９が、取付穴６１の下方に配置されて、矢印６２及び矢印６３のように軸方向に押込まれる。この軸方向の押込みによって、アッパーグロメット７とロワーグロメット９は、係止爪４２と係止爪４８とが係合して、図９（Ｂ）に示すように、マット６を挟持した状態に固定される。なお、マット６の取付穴６１は、アッパーグロメット７及びロワーグロメット９の形状に合わせて、大径穴と小径穴とで形成されるようにしてもよい。 As shown in FIG. 9A, the upper grommet 7 is disposed above the mounting hole 61 of the mat 6, and the lower grommet 9 is disposed below the mounting hole 61, as indicated by arrows 62 and 63. Pushed in the axial direction. By this axial pushing, the upper grommet 7 and the lower grommet 9 are fixed in a state in which the mat 6 is sandwiched as shown in FIG. Is done. The attachment hole 61 of the mat 6 may be formed by a large diameter hole and a small diameter hole in accordance with the shapes of the upper grommet 7 and the lower grommet 9.

図１０〜図１１は、本発明のマットの固定装置６６を用いて、マット６をパッド５に取付けた状態を示している。第１クリップ１がパッド５に取付けられる。図１０において、第１クリップ１は、パッド５の上下面に形成されたガイド溝に合わせて、パッド５の側面に位置合わせされ、側面から押込まれる。固定部１５の弾性逆止爪１８が、パッド５に形成された係止凹部６５Ａ及び６５Ｂに係合して、第１クリップ１は、パッド５に固定される。第１クリップ１のパッド５への固定はスライド作業だけなので、作業は簡単で作業時間も短い。図示の実施形態において、マットの固定装置６６は、第１クリップ１と第２クリップ２と取付ノブ３とマット固定具１０とから成る。 10 to 11 show a state where the mat 6 is attached to the pad 5 by using the mat fixing device 66 of the present invention. The first clip 1 is attached to the pad 5. In FIG. 10, the first clip 1 is aligned with the side surface of the pad 5 in accordance with the guide grooves formed on the upper and lower surfaces of the pad 5 and pushed from the side surface. The elastic check pawl 18 of the fixing portion 15 engages with the locking recesses 65 A and 65 B formed on the pad 5, and the first clip 1 is fixed to the pad 5. Since the fixing of the first clip 1 to the pad 5 is only a slide operation, the operation is simple and the operation time is short. In the illustrated embodiment, the mat fixing device 66 includes a first clip 1, a second clip 2, a mounting knob 3, and a mat fixing tool 10.

図１０〜図１１に示すように、マット６をフロアパネル４等の被取付部材に取付ける際、図示の実施形態においては、パッド５の上及びパッド５に固定された第１クリップ１の固定部１５の上部アームの上に、遮音や断熱等の目的でインシュレータ１１が配置され、更にカーペット等のカバー１３がインシュレータ１１の上に配置される。例えば、自動車の組み付けラインにおいて、第１クリップ１が固定されたパッド５のある場所に、取付ノブ３によって第２クリップ２が固定されたマット６が搬入される。マット６に固定された第２クリップ２の連結部２５が、パッド５に固定された第１クリップ１の連結部１７を収容できるように、マット６がパッド５の第１クリップ１に位置決めされる。位置決め後、マット６とともに第２クリップ２が第１クリップ１に押込められる。この押込みによって、第２クリップ２の連結部２５の中に第１クリップ１の連結部１７が挿入され、連結部１７の一対の弾性係止片２１が連結部２５の一対の係止肩１９にそれぞれ係合して、第１クリップ１と第２クリップ２とが連結される。 As shown in FIGS. 10 to 11, when the mat 6 is attached to a member to be attached such as the floor panel 4, in the illustrated embodiment, the fixing portion of the first clip 1 fixed on the pad 5 and the pad 5. An insulator 11 is disposed on the upper arm 15 for the purpose of sound insulation and heat insulation, and a cover 13 such as a carpet is disposed on the insulator 11. For example, in the assembly line of an automobile, the mat 6 to which the second clip 2 is fixed by the mounting knob 3 is carried into a place where the pad 5 to which the first clip 1 is fixed is located. The mat 6 is positioned on the first clip 1 of the pad 5 so that the connecting portion 25 of the second clip 2 fixed to the mat 6 can accommodate the connecting portion 17 of the first clip 1 fixed to the pad 5. . After positioning, the second clip 2 is pushed into the first clip 1 together with the mat 6. By this pushing, the connecting portion 17 of the first clip 1 is inserted into the connecting portion 25 of the second clip 2, and the pair of elastic locking pieces 21 of the connecting portion 17 are engaged with the pair of locking shoulders 19 of the connecting portion 25. The first clip 1 and the second clip 2 are connected by engaging with each other.

図１０（Ａ）では、取付ノブ３が軸回りに回転する前の非ロック位置の姿勢にある。図１０（Ｂ）では、取付ノブ３が軸回りに９０度回転した、ロック位置の姿勢にある。すなわち、取付ノブ３は、第２クリップ２に本止め連結されるとともに、取付ノブ３のつまみ部５１の下面のフランジ部分が、マット固定具１０のアッパーグロメット７の保持部４１の上面に堅く係合して、マット６を第２クリップ２に堅く固定する。図１１の（Ａ）及び（Ｂ）に図示のように、第１クリップ１と第２クリップ２の連結及び取付ノブ３によるマット６と第２クリップ２の連結によって、マット６が、第１クリップ１及び第２クリップ２（及び取付ノブ３）を介してパッド５に固定される。更に、パッド５はフロアパネル４に固定される。また、パッド５の上及び第１クリップ１の固定部１５の上部アーム上に配置されたインシュレータ１１及びカバー１３は、第２クリップ２のフランジ２６に押圧されてパッド５の上に固定される。上記のように、予め、第２クリップ２に取付ノブ３を仮止め連結（取付ノブ３を非ロック位置の姿勢で連結すること）し、マット６を取付ノブ３によって第２クリップ２に仮止め連結しておけば、自動車の生産ラインにおいては、パッド５に固定された第１クリップ１に、第２クリップ２を位置決めして押込むだけの簡単な操作でマット６をパッド５（ひいてはフロアパネル４）等の被取付部材に固定することができ、生産ラインにおける作業時間も短い。 In FIG. 10A, the attachment knob 3 is in the unlocked position before rotating around the axis. In FIG. 10 (B), the mounting knob 3 is in the locked position posture rotated 90 degrees around the axis. That is, the attachment knob 3 is permanently connected to the second clip 2 and the flange portion of the lower surface of the knob portion 51 of the attachment knob 3 is firmly engaged with the upper surface of the holding portion 41 of the upper grommet 7 of the mat fixture 10. Together, the mat 6 is firmly fixed to the second clip 2. As shown in FIGS. 11A and 11B, by connecting the first clip 1 and the second clip 2 and connecting the mat 6 and the second clip 2 by the mounting knob 3, the mat 6 becomes the first clip. It is fixed to the pad 5 via the first and second clips 2 (and the mounting knob 3). Further, the pad 5 is fixed to the floor panel 4. The insulator 11 and the cover 13 disposed on the pad 5 and on the upper arm of the fixing portion 15 of the first clip 1 are pressed by the flange 26 of the second clip 2 and fixed on the pad 5. As described above, the attachment knob 3 is temporarily fixedly connected to the second clip 2 (the attachment knob 3 is connected in the unlocked position), and the mat 6 is temporarily fixed to the second clip 2 by the attachment knob 3. If they are connected, in the automobile production line, the mat 6 can be put into the pad 5 (and thus the floor panel) by a simple operation of positioning and pushing the second clip 2 into the first clip 1 fixed to the pad 5. 4) It can be fixed to a member to be attached and the work time in the production line is short.

マット６の清掃や交換等のためにマット６をパッド５から取外す場合は、マット６を強く引上げて第２クリップ２を第１クリップ１から強く引き抜けばよい。これは、弾性係止片２１の下方側の面２２（図１（Ｆ）参照）がほぼ４５度の傾斜面として形成されているからである。すなわち、第２クリップ２の強い引き抜き力で第２クリップ２の連結部２５の係止肩２９が乗り越えられるように、ほぼ４５度の傾斜面として形成され、第１クリップ１に連結した第２クリップ２を強い力で引き抜くことができ、第２クリップ２に連結されたマット６を、パッド５が固定されたフロアパネル４から取外すことができる。この取外し作業は、マット６を手で強く引き抜くことによってもできるが、マイナスドライバ等の工具先端を、マット６とカバー１３の間に入れて、こじることによってもできる。清掃後、取外したマット６を、再度フロアパネル等の被取付部材に取付けるには、第２クリップ２の連結部２５が第１クリップ１の連結部１７に収容できるように、マット６をパッド５に位置決めし、マット６とともに第２クリップ２を第１クリップ１に押込めばよい。なお、マット６の交換等のため、取外したマット６から第２クリップ２を取外すには、取付ノブ３を、ロック位置から非ロック位置に、９０度回転させれば、取付ノブ３を取り外しでき、それによって、第２クリップ２をマット６から取外すことができる。 When the mat 6 is removed from the pad 5 for cleaning or replacement of the mat 6, the mat 6 may be pulled up and the second clip 2 may be pulled out of the first clip 1. This is because the lower surface 22 (see FIG. 1 (F)) of the elastic locking piece 21 is formed as an inclined surface of approximately 45 degrees. That is, the second clip connected to the first clip 1 is formed as an inclined surface of approximately 45 degrees so that the engaging shoulder 29 of the connecting portion 25 of the second clip 2 can get over by the strong pulling force of the second clip 2. 2 can be pulled out with a strong force, and the mat 6 connected to the second clip 2 can be removed from the floor panel 4 to which the pad 5 is fixed. This removal work can be done by pulling out the mat 6 by hand, but can also be done by putting the tip of a tool such as a flathead screwdriver between the mat 6 and the cover 13 and twisting. In order to attach the removed mat 6 to a member to be attached again such as a floor panel after cleaning, the mat 6 is placed on the pad 5 so that the connecting portion 25 of the second clip 2 can be accommodated in the connecting portion 17 of the first clip 1. And the second clip 2 together with the mat 6 may be pushed into the first clip 1. To remove the second clip 2 from the removed mat 6 for replacement of the mat 6, etc., the mounting knob 3 can be removed by rotating it 90 degrees from the locked position to the unlocked position. Thereby, the second clip 2 can be detached from the mat 6.
