[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a clip for fixing members to each other, and particularly to a clip structure that can be easily fixed without rotating with respect to a bolt provided on the member.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, this type of clip 40 is provided with a hole 42 for inserting a bolt in the center of a main body 41 formed by pressing into an inverted conical shape. There has been proposed a structure in which pieces extending on both sides of the extension of the diameter of the main body 41 are bent toward the conical convex portion and provided with blade-like leg pieces 43. Each leg piece 43 is arrange | positioned so that the hole 42 may be pinched | interposed.
[0003]
The clip 40 described above is used when the members are simply fixed in place of the bolts and nuts. For example, as shown in FIG. 5, the clip 40 blocks the silencer 61 mounted on the bottom surface 51 of the vehicle body. The hot plate 71 is fixed. That is, the heat shield plate 71 is fixed by attaching the heat shield plate 71 to the bolt 52 fixed to the bottom surface 51 of the vehicle body and fixing the clip 40 to the bolt 52 on which the thread 53 is formed. When fixing, the hole portion 42 of the clip 40 is arranged in the bolt 52 so that the leg piece 43 of the clip 40 is downward, and the clip 40 is pushed into the bolt 52 to be fixed to the bottom surface 51 of the vehicle body. The heat shield plate 71 is temporarily fixed with the bolts 52 sandwiched between the leg pieces 43.
[0004]
In this state, the bottom surface 51 of the vehicle body and the heat shield plate 71 are not in close contact (the leg piece 43 is not in contact with the bottom surface 51 of the vehicle body and the contact force is weak). When the piece 43 gets over the screw thread 53 of the bolt 52 by several pitches, the peripheral wall of the hole 42 of the clip 40 is fitted to the screw thread 53 of the bolt 52, and the leg piece 43 is brought into contact with the bottom surface 51 of the vehicle body so that the elastic force ( The clip 40 is fixed in a state where a force that presses the heat shield 71 against the bottom surface 51 of the vehicle body is generated.
[0005]
[Problems to be solved by the invention]
However, according to the clip 40, since the peripheral wall of the hole 42 of the clip 40 is fitted and fixed to the thread 53 of the bolt 52, the size of the hole 42 is different for different bolt diameters. There was a problem that it was necessary to change, and versatility was poor.
[0006]
Further, since the leg piece 43 extending in the diameter direction of the main body 41 is provided, there has been a drawback that a developed area (dotted line portion 43 ′) in the leg piece forming direction before press working becomes long.
[0007]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a clip that can be used for a wide range of bolt diameters having slightly different diameters and that has a simple structure and can be manufactured at low cost.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a clip according to the present invention is a clip that is integrally formed from a metal plate, and includes an annular base portion that is located on a horizontal plane, and a plurality of cut portions that pass through a center point on an inner portion of the annular base portion. A plurality of triangular inclined pieces formed by inclining triangular pieces sandwiched by the cut portions so that the top end side is positioned on the upper side, and an outer portion of the annular base portion are inclined in the opposite direction to the triangular inclined pieces. A plurality of substantially rectangular leg pieces formed at opposing positions ;
The leg piece is arranged at a position facing the notch and has a shape in which the outside is wide, and has an opening at the center.
[0009]
2. The clip according to claim 1, wherein a pair of upright pieces formed on the outer portion of the annular base portion so as to incline perpendicularly in the same direction as the triangular inclined piece so as to rotate the clip. It is preferable to have.
[0010]
When the clip of the present invention is attached to the bolt, the screw thread of the bolt is supported and fixed at the tops of the tips of the inclined plurality of triangular inclined pieces. At this time, the distance between the apexes of the tips can be adjusted by the inclination angle of the triangular inclined piece, and it is possible to cope with different bolt diameters when fixing the clip.
[0011]
Further, by forming the standing piece, the clip can be easily rotated by picking up the standing piece, and the clip can be released from being fixed to the bolt.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
A clip as an example of an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
1 (a), (b) and (c) are plan explanatory views, a front view and a side view of the clip, respectively, (d) and (e) are cross-sectional explanatory views, and FIG. 2 is a developed shape of the clip before being pressed. FIG.
[0013]
The clip 10 according to the present invention is integrally formed by pressing a metal plate in which a cut portion 2 and cutout portions 3 and 4 are formed on a disc 1 as shown in FIG. When the disk 1 of FIG. 2 is pressed, the clip 10 has a three-dimensional shape as shown in FIG. The clip 10 is formed in an annular base portion 11 positioned on a horizontal plane in the plan view of FIG. 1A, a plurality of triangular inclined pieces 13 formed on an inner portion of the annular base portion 11, and an outer portion of the annular base portion 11. The plurality of leg pieces 15 are configured.
[0014]
The shape of the annular base 11 does not change before and after pressing. Three incisions 2 that pass through the center point are formed in the inner portion of the annular base 11, and six triangular pieces sandwiched between the incisions 2 so that the top end side is positioned on the upper side by pressing. Is bent at the bottom side so that it is inclined with respect to the annular base 11. A hole 14 into which a bolt to be described later is inserted is formed in a portion surrounded by the tops of the tips of the six triangular inclined pieces 13.
[0015]
Two pairs of substantially rectangular leg pieces 15 are formed on the outer portion of the annular base 11 so as to be inclined in the opposite direction to the triangular inclined piece 13 by pressing, and are formed at positions facing each other. The outer end portion of each leg piece 15 is bent 16 on the triangular inclined piece side to form a surface parallel to the annular base portion 11.
Each leg piece 15 is arranged at a position facing the notch 2 and is formed in a slightly wider rectangular shape on the outside. An opening 17 is formed at the center of each leg piece 15 so as to give an elastic force that is easily deformed with respect to a load applied to the annular base 11.
[0016]
In addition, a pair of rectangular shapes are formed on the outer portion of the annular base portion 11 so as to face each other so as to incline vertically in the same direction as the triangular inclined piece 13 at a position corresponding to the cut portion 2 where the leg pieces 15 do not face each other. A standing piece 18 is formed.
[0017]
Next, a method of using the clip 10 having the above structure will be described with reference to FIG.
First, when the heat shield plate 71 is attached to the bolt 52 fixed to the bottom surface 51 of the vehicle body, the heat shield plate 71 is inserted so that the bolt 52 is inserted into the hole 72 corresponding to the bolt 52 formed in the heat shield plate 71. Installing.
Next, the hole 14 of the clip 10 is inserted into the bolt 52 so that the leg piece 15 of the clip 10 contacts the heat shield plate 71.
[0018]
When the clip 10 inserted into the bolt 52 is pushed in, the leg piece 15 is deformed in a direction in which the inclination becomes gentle, and the top of each triangular inclined piece 13 moves so as to bite the deeper pitch of the thread 53. In addition, an elastic force is applied to the annular base 11, and the top of the triangular inclined piece 13 is fitted to the thread 53. In this state, the annular base 11 and the leg piece 15 are pushed toward the heat shield 71 by the tops of the respective triangular inclined pieces 13 of the clip 10, so that the heat shield 71 and the vehicle body bottom 51 are secured. Can do.
[0019]
According to the above structure, the bending force is formed 16 on the distal end side of the leg piece 15, whereby an elastic force can be applied smoothly to the annular base portion 11. That is, when the bending formation 16 is not performed, when the elastic force is applied, the outer end portion of the leg piece 15 becomes a claw and may bite into the heat shield plate 71. As a result, the inclination angle of the leg piece 15 Deformation will be prevented, and smooth elastic force cannot be applied.
Further, by forming the bend 16, it becomes easy to slip when the elastic force is urged, and it is possible to prevent the heat shield 71 from being damaged.
[0020]
When the heat shield 71 using the clip 10 is fixed to the bottom surface 51 of the vehicle body, each leg piece 15 is pressed against the heat shield 71 so that a spring force is generated. Sticking can be prevented.
[0021]
Further, when the clip 10 is mounted, the top of the triangular inclined piece 13 is moved along the thread 53 so that the clip 10 can be easily removed from the bolt 52 by pinching the standing piece 18 and rotating it in a direction away from the bolt 52. Can be removed.
[0022]
Since the diameter of the hole 14 formed in the portion surrounded by the top of each triangular inclined piece 13 can be adjusted by the inclined position of the triangular inclined piece 13, the same clip 10 can be used for different bolt diameters.
[0023]
In the case of mounting on the bolt 52, in the case of the clip 40 described in the conventional example, the bolt head is hidden by the inverted conical main body 41, whereas in the clip 10 of the present invention, the cut portion 2 becomes a slit and a triangular inclined piece. Since the back side of 13 can be seen, there is an advantage that the position of the head of the bolt 52 can be confirmed and the insertion is easy.
[0024]
Further, since the blade-like leg piece 43 extending outward is not provided unlike the clip 40 of the conventional example, the development area can be reduced and the manufacturing cost can be reduced.
[0025]
【The invention's effect】
According to the present invention, when mounting to the bolt, the screw threads of the bolt are supported and fixed at the top ends of the plurality of inclined triangular inclined pieces. The diameter of the hole) can be adjusted, and a highly versatile structure that can be attached to different bolt diameters when fixing the clip can be obtained.
[0026]
In addition, by forming the standing piece, when mounting the clip, it can be easily rotated in the direction to pinch the standing piece and remove from the bolt, and the top of the triangular piece is moved along the thread to clip from the bolt The structure can be easily removed.
