It is formed as follows. In the hole 33, each of a pair of horizontally opposed corners is continuous with a T-shaped slit 34 extending outward. Further, in the hole 33, a pair of vertically opposed corners is formed as a recess 35 that receives a protruding portion 59 that protrudes outwardly and is formed on the pair of locking legs of the mounting knob 10. A pair of locking legs 54 of the mounting knob 10 are inserted into the rectangular holes 33 so as to be aligned with a pair of horizontally opposed corners. When the mounting knob 10 is rotated 90 degrees around the axis, the hole 33 expands due to the elasticity provided by the slit 34, allowing the mounting knob 10 to rotate 90 degrees, and when the rotation of 90 degrees is completed. The projections 59 of the pair of locking legs 54 of the mounting knob 10 are fitted into the recesses 35 of the holes 33 so that the locking legs 54 remain in their positions, and the holes 33 return to their original sizes and are mounted. The posture of the knob 10 is maintained in a state rotated by 90 degrees. The fitting between the convex portion 59 and the concave portion 35 of the locking leg 54 of the mounting knob 10 gives the feel (click) to the hand of the operator who operates the mounting knob 10 and reports the end of the 90-degree rotation. . When the attachment knob 10 is rotated 90 degrees, the engagement portion 58 of the engagement leg 54 is engaged with the engagement shoulder 37 of the support portion 27, and the attachment knob 10 is attached to the support portion 27. The locking shoulder 37 is formed at the lower end of the support portion 27. The upper surface of the support portion 27 is a surface that supports the lower grommet 9 when the mat 6 is supported. Since the hole 33 for receiving the mounting knob 10 regulates the direction of the mounting knob 10, an arrow mark 38 is formed on the surface of the flange 26 to display the direction to the operator and help the work. Yes. The arrow mark 38 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.

  With reference to FIG.3 and FIG.4, the mat fixing tool 11 comprised from the upper grommet 7 and the lower grommet 9 is demonstrated. The basic configuration of such a fixture is described in Patent Document 3 (Japanese Patent Laid-Open No. 2002-193016), and should be referred to. 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 FIGS. 6 and 7, 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 around the hole of the flexible mat 6, especially the mat 6. Reinforce and strengthen the attachment to other members and prevent breakage from around the hole.

  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 41 in contact with one surface and a plate-like holding portion 42 projecting inwardly 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 43 are provided on the outer peripheral surface of the inner cylinder portion 39 in order to connect the upper grommet 7 and the lower grommet 9 to each other. The shape of the locking claw 43 is a shape that can be easily inserted but resists extraction.

  The inner cylinder part 39 is formed hollow, and a plate-like holding part 42 is formed at an intermediate height position of the inner cylinder part 39 (not in the fixture of Patent Document 3). The holding portion 42 is formed with an elliptical hole 45 through which the locking leg 54 of the mounting knob 10 passes. The flange 41 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. On the lower surface of the flange 41, a plurality of protrusions 46 that 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 are formed, and the rotation of the upper grommet 7 is prevented.

  In FIG. 4, the lower grommet 9 is inserted into the mounting hole of the mat 6 and receives the inner cylinder portion 39 of the upper grommet 7 so as to become an outer cylinder. And a flange 49 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 47 is preferably shorter as long as the inner cylinder part 39 of the upper grommet 7 can be stably received. An outer diameter of the outer cylinder portion 47 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 is easily inserted and does not rattle after insertion. A plurality of elastic locking claws 50 are provided in a portion adjacent to the flange 49 on the inner side of the outer cylindrical portion 47 in order to connect the upper grommet 7 and the lower grommet 9 to each other. Each locking claw 50 is locked to the locking claw 43 of the inner cylindrical portion 39 of the upper grommet 7. Each latching claw 50 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 the latching claw 43 in the extraction direction. The flange 49 is formed as a disk having a certain size that comes into contact with the mat surface on the side opposite to the flange 41 of the upper grommet 7 at the periphery of the mat mounting hole. On the upper surface of the flange 49, a plurality of protrusions 51 protrude in a triangular shape so as to bite into the mat 6 and are formed at intervals in the circumferential direction. Since the protrusion 51 bites into the mat, the holding force to the mat is improved.

  Note that the outer shape of the inner cylinder portion 39 of the upper grommet 7 and the outer shape of the outer cylinder portion 47 of the lower grommet 9 may be cylindrical, but as shown in FIGS. 3D and 4B. In addition, it is preferable that the inner cylinder part 39 is formed in an oval shape so that it can be accommodated almost perfectly in the outer cylinder part 47, and the direction (angle) in the rotational direction can be regulated in the connection of both grommets 7 and 9. Thereby, the engagement between the locking claw 43 of the upper grommet 7 and the locking claw 5 of the lower grommet 9 can be ensured.

  The attachment knob 10 will be described with reference to FIG. The mounting knob 10 is integrally formed of a hard synthetic resin material. A part of known knobs similar to the mounting knob 10 are described in, for example, Patent Document 4 (Design Registration No. 1296907). The attachment knob 10 is used to attach the mat 6 sandwiched between the upper grommet 7 and the lower grommet 9 to the second clip 2. The mounting knob 10 includes an upper knob portion 53 and a pair of locking legs 54 that hang downward from the knob portion 53. As shown in FIGS. 9, 12, and 13, the knob portion 53 is formed to a size that fits inside the inner cylinder portion 39 and the flange 41 of the upper grommet 7. The knob portion 53 has an upper portion formed in a shape that can be operated by a worker with a finger or the like, and a lower surface side of the knob portion 53 is a flange that comes into contact with the holding portion 42 of the upper grommet 7 of the mat fixture 11 holding the mat 6. Furthermore, a stopper 55 that protrudes downward in a circular shape around the axis is formed on the lower surface side. The stopper 55 is housed in a shallow circular recess 57 (see FIGS. 2B, 2F, etc.) formed around the square hole 33 of the support portion 27 of the second clip 2 and attached. This prevents (stops) the knob 10 from further squeezing into the support portion 27 of the second clip 2 and smoothly guides the rotation of the mounting knob 10 around the axis.

  The pair of locking legs 54 of the mounting knob 10 penetrate the upper grommet 7 and the lower grommet 9 that sandwich the mat 6, and the tips of the locking legs 54 pass through the holes 33 of the support portion 27 of the second clip 2. Extending to the locking shoulder 37. A locking portion 58 is formed at the tip of each locking leg 54. The locking portion 58 extends through the upper grommet 7 and the lower grommet 9 sandwiching the mat 6 and further extends through the hole 33 of the support portion 27 of the second clip 2 by operating the knob portion 53. When 54 is rotated by 90 degrees around the axis, the mat 6 held by the mat fixing tool 11 is connected to the second clip 2 by engaging with the engaging shoulder 37 of the support portion 27 of the two clips 2. . Each locking leg 54 is formed with a rib-like convex portion 59 extending in the longitudinal direction protruding outward in the radial direction at a portion from the lower surface of the knob portion 53 to the front side reaching the locking portion 58. The convex portion 59 maintains the rigidity of each locking leg high, and when the mounting knob 10 is rotated 90 degrees, the convex portion 59 fits into the concave portion 35 of the hole 33 of the support portion 27 of the second clip 2. Thus, the state in which the locking portion 58 is locked to the locking shoulder 37 is maintained, and the mat 6 is attached to the second clip 2. Further, the click feeling when the convex portion 59 is fitted into the concave portion 35 can inform the operator of the completion of the 90-degree rotation operation.

  As in the first embodiment described above, a mat mounting device including the first clip 1, the second clip 2, the mat fixture 11 including the upper grommet 7 and the lower grommet 9, and the mounting knob 10 is provided. The operation of locking the mat 6 to the pad 5 fixed to the floor panel 3 will be described with reference to FIGS.

  As shown in FIG. 6, 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, and is axially indicated by arrows 62 and 63. It is pushed into. By this axial pushing, the upper grommet 7 and the lower grommet 9 are fixed in a state where the mat 6 is sandwiched as shown in FIG. . 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.

  FIG. 8 shows a state in which the attachment knob 10 is arranged in the mat fixture 11 for connection of the second clip 2. As shown in FIG. 9, the second clip 2 is disposed below the mat 6 and directly below the lower grommet 9, and causes the flange 26 to contact the lower grommet 9. In the mounting knob 10 arranged at the position of FIG. 8, the locking leg 53 passes through the holding portion 42 of the upper grommet 7 and further passes through the hole 30 of the support portion 27 of the second clip 2 through the lower grommet 9. In this way, it is pushed into the second clip 2 (arrows 65 and 66). After the pushing, as shown by an arrow 67 in FIG. 9, the attachment knob 10 is rotated 90 degrees around the axis center by the operator with the knob portion 53. By this rotation, the locking portion 58 of the locking leg 54 is locked to the locking shoulder 29 of the support portion 27, and the second clip 2 is connected to the mat 6. The state after this connection is shown in the upper part of FIG. In this embodiment, the work of connecting the second clip 2 to the mat 6 is performed by the mat manufacturer. Therefore, in the assembly line of the automobile, if the mat 6 to which the second clip 2 is attached is received and the second clip 2 is attached to the first clip 1 by pressing, the mat 6 can be attached to the attached member. Assembling work on the assembling line can be simplified and the working time can be shortened.

  On the other hand, the 1st clip 1 is attached to the pad 5, as shown in FIG.10 and FIG.11. In FIG. 10, the first clip 1 is aligned with the side surface of the pad 5 in accordance with the guide groove 14 formed in the pad 5 (the whole shape is shown in the perspective view of FIG. 16). After the alignment, when it is pushed in the direction of the arrow 67, the upper and lower arm portions of the fixing portion 15 move so as to slide in the guide groove. At the end of pushing, the elastic check pawl 18 engages with the locking recesses 69 </ b> A and 69 </ b> B formed in 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.

  As shown in FIG. 12, when the mat 6 is attached to a member to be attached such as the floor panel 3, in the illustrated embodiment, on the pad 5 and above the fixing portion 15 of the first clip 1 fixed to the pad 5. An insulator 13 is disposed on the arm for the purpose of sound insulation and heat insulation, and a cover 70 such as a carpet is disposed on the insulator 13. For example, in an assembly line of an automobile, a mat 6 to which the second clip 2 is fixed is carried into a place where the pad 5 to which the first clip 1 is fixed is present.
