  The main problem to be solved by the present invention is that a clip that is fastened to an arbitrary position of the stud bolt with one touch by inserting the stud bolt can be easily removed from the stud bolt.

In order to achieve the above object, in the present invention, a clip is provided with a base portion provided with a stud bolt passage portion;
A side wall portion provided on both sides of the base portion and connected to the base portion with a connecting portion;
An elastic engagement piece projecting inwardly from the side wall so as to position the engagement end of the stud bolt with respect to the threaded portion on the distal end side of the stud bolt inserted from the base portion;
The side wall portion is configured to be movable inward while elastically deforming at least the connecting portion from a state where the engaging end of the elastic engaging piece is engaged with the inserted stud bolt, and
It is assumed that the base is provided with an abutting portion that abuts on the elastic engagement piece at the base side of the stud bolt from the engagement end of the elastic engagement piece during the movement.

  According to such a configuration, first, when the stud bolt is inserted from the tip end side through the clip through the base through the clip, the elastic engagement piece that applies the engagement end to the threaded portion of the stud bolt is used as the engagement end. Such insertion can be allowed by being elastically deformed so as to approach the side wall. When the insertion is stopped at an arbitrary position, the elastic engagement piece is elastically restored, and the engagement end is inserted into the screw groove constituting the thread portion of the stud bolt, and the clip is inserted at the arbitrary position. Can be fastened to.

  Secondly, by pressing the side wall portion inward while elastically deforming the connecting portion from the state where the clip is fastened to the stud bolt, the side wall portion is moved to the base side of the stud bolt, The engagement end of the elastic engagement piece can be pulled out from the threaded portion of the stud bolt, and the engagement between both can be released. At the same time, the contact of the side wall portion during the movement can maintain the posture of the elastic engagement piece having the engagement end moved to the position where the engagement with the screw portion of the stud bolt is released as long as the pressing is continued. I am doing so. In other words, if there is no such contact portion, the elastic engagement piece is once moved to the tip side of the stud bolt even if the elastic engagement piece is once disengaged from the screw portion by the movement of the side wall portion toward the root side of the stud bolt. It is elastically returned to this screw part and is re-engaged by changing the location, but by having such a contact part, the elastic return of the elastic engagement piece can be prevented with this contact part as a fulcrum, As a result, when the clip is moved to the tip end side of the stud bolt while pressing, the engaging end does not change the place and engages with the screw portion again.

  One of the preferred embodiments of the present invention is to provide at least a part of the connecting portion along an imaginary line segment that obliquely crosses the central axis of the stud bolt to be inserted.

  If a bridging portion that connects between the side wall portions on both sides of the base portion is further provided, a force suitable for the pressing of the side wall portion is required, and the fastening force of the clip to the stud bolt is increased. It can be kept above a certain level.

  In the clip according to the present invention, the clip is fastened to the stud bolt by moving the clip to the distal end side of the stud bolt while pressing the side wall portions on both sides of the base portion of the clip fastened to the stud bolt. The attached state can be released and the two can be separated. In particular, the operator can perform this operation with one hand.

FIG. 1 is a perspective view of a clip. FIG. 2 is a front view of the clip. FIG. 3 is a side view of the clip. FIG. 4 is a cross-sectional view of the stud bolt with a clip fastened thereto. FIG. 5 is a cross-sectional view of the state where the pressed portions of the left and right side wall portions of the clip are pressed inward from the state of FIG.

  Hereinafter, a typical embodiment of the present invention will be described with reference to FIGS. The clip C according to this embodiment is fastened to an arbitrary position of the stud bolt B with one touch by inserting the stud bolt B. Typically, such a clip C is used to be fastened to the stud bolt B so as to hold the object to be held between the clip C and the member on which the stud bolt B is erected. Alternatively, the clip C is typically a member that is fastened to the stud bolt B and is held by a holding portion (not shown) that is appropriately provided on the clip C, and the like. Used to attach via C. In the illustrated example, such a clip C is used to hold the planar member M that is stuck on the panel P on which the stud bolt B is erected. The planar member M is provided with a through hole Ma for the stud bolt B, and the planar member M is stuck on the panel P through the stud bolt B through the through hole Ma. The clip C is fastened to a portion of the stud bolt B protruding from the upper surface of the planar member M and sandwiches the planar member M with the panel P. Specifically, the clip C is moved to the base side of the stud bolt B so as to receive the stud bolt B from the tip Ba into the clip C. At this time, the left and right elastic engagement pieces 4 and 4 constituting the clip C are elastically deformed in a direction in which the engagement ends 4a are separated from each other by contacting the threaded portion Bb of the stud bolt B. A simple movement of B to the root side is allowed. When the movement is stopped at the position where the clip C is in contact with the upper surface of the planar member M, the elastic engagement piece 4 is elastically restored and the engagement end 4a is engaged with the threaded portion Bb of the stud bolt B. As a result, the clip C is fastened to the stud bolt B.

  In the clip C according to this embodiment, the left and right side walls 2 and 2 (described later) are pressed inward from the state of being fastened to the stud bolt B in this way, so that the elastic engagement piece 4 The engagement end 4a and the threaded portion Bb of the stud bolt B can be disengaged, and the clip C is moved to the tip Ba side of the stud bolt B while maintaining this pressed state, whereby the stud bolt B The clip C can be easily removed from

  The clip C includes a base portion 1, a side wall portion 2, a connecting portion 3, an elastic engagement piece 4, and a bridging portion 5.

  The base portion 1 and the bridging portion 5 are provided with through portions 1a and 5a for stud bolts B, respectively. A bridging portion 5 is provided above the base portion 1 with a gap between the base portion 1 and the base portion 1. Both the base portion 1 and the bridging portion 5 are configured to have a substantially square plate shape arranged so that the plate surface is orthogonal to the central axis x of the stud bolt B to be inserted. The through portions 1a and 5a are configured as round holes substantially equal to the outer diameter of the stud bolt B formed in the base portion 1 and the bridging portion 5 so as to penetrate therethrough.

  The side wall portions 2 are provided on both the left and right sides of the base portion 1, and the connecting portion 3 is connected to the base portion 1 with a gap from the base portion 1. In the illustrated example, the side wall portion 2 is configured by a plate-like body having the same width as the length of one side of the base portion 1 and the bridging portion 5.

  The lower end 2 a of the side wall 2 is located below the base 1. The lower end 2a of the right side wall portion 2 and the right side of the base portion 1 are integrally connected via the connecting portion 3, and the lower end 2a of the left side wall portion 2 and the left side of the base portion 1 are integrally connected via the connecting portion 3. It is connected to. Further, the upper end 2 f of the right side wall portion 2 is integrally connected to the right side of the bridging portion 5, and the upper end 2 f of the left side wall portion 2 is integrally connected to the left side of the bridging portion 5.

  Between the lower end 2a of the side wall portion 2 and a portion where the level is substantially the same as the level of the upper surface 1b of the base portion 1, it is parallel to the central axis x of the stud bolt B to be inserted. It is a pressing place 2b to be made. Between the pressing part 2b and the bridge part 5 in the side wall part 2, it inclines in the direction which approaches the central axis x of the stud bolt B inserted as it goes upwards.

  The connecting portion 3 is provided between a corner between the thickness-side end surface 1 c facing the side wall 2 in the base 1 and the lower surface 1 d of the base 1 and a lower end 2 a of the side wall 2. Yes. Since the base portion 1 is positioned above the lower end 2a of the side wall portion 2, the connecting portion 3 is separated from the central axis x of the stud bolt B inserted from the base portion 1 side toward the lower end of the connecting portion 3. It is inclined to. That is, the connecting portion 3 is provided along a virtual line segment that obliquely crosses the central axis x of the stud bolt B to be inserted.

  The elastic engagement piece 4 is inward from the side wall portion 2 so that the engagement end 4a of the stud bolt B to be inserted with respect to the screw portion Bb is positioned closer to the tip Ba side of the stud bolt B to be inserted than the base portion 1. Sticks out. In the illustrated example, the elastic engagement pieces 4 are protruded inward from the inner surfaces of the pressing locations 2b of the left and right side wall portions 2 and 2, respectively. The elastic engagement piece 4 is configured to have a plate shape narrower than the side wall 2. The front edge 2d of the side wall 2 and the front edge 4d of the elastic engagement piece 4 and the rear edge 2e of the side wall 2 and the rear edge 4e of the elastic engagement piece 4 are spaced substantially equal. A connecting portion 4 f of the elastic engagement piece 4 with the pressing portion 2 b of the side wall 2 is positioned below the upper surface 1 b of the base 1. The elastic engagement piece 4 is provided so as to be inclined upward from the connecting portion 4f, and is configured to approach the center axis x of the stud bolt B that is inserted toward the engagement end 4a. The engaging end 4a is formed so as to be a straight edge substantially parallel to the side of the base 1 facing the side wall 2. In the illustrated example, the upper end portion of the elastic engagement piece 4 is slightly bent in a direction substantially perpendicular to the center axis x of the stud bolt B, and the bent upper end portion functions as the engagement end 4a. It has become. The upper surface 4b of the engaging end 4a is a surface orthogonal to the central axis x of the stud bolt B to be inserted, and the lower surface 4c of the engaging end 4a is one screw groove constituting the threaded portion Bb of the stud bolt B. It is configured to follow the inclination of the groove wall. The distance between the engagement ends 4a of the left and right elastic engagement pieces 4 and 4 is set to be slightly smaller than the diameter at the top of the screw thread constituting the threaded portion Bb of the stud bolt B to be inserted. is there.

  When the stud bolt B is inserted into the clip C from the leading end Ba side of the base 1 so as to be pulled out upward from the passing portion 5a of the bridging portion 5, the engaging end 4a of the elastic engaging piece 4 becomes the stud. The elastic engagement piece 4 hits the threaded portion Bb of the bolt B and is elastically deformed in such a direction that the engagement end 4a approaches the side wall portion 2 to allow such insertion. When the insertion is stopped at an arbitrary position, the elastic engagement piece 4 is elastically restored and the engagement end 4a is inserted into the thread groove constituting the threaded portion Bb of the stud bolt B, so that the stud bolt B is inserted at the arbitrary position. It comes to stick. If the clip C is screwed from this fastened state, the clip C is guided by the threaded portion Bb of the stud bolt B and gradually changes its fastened position.

  In this embodiment, the side wall portion 2 is moved while elastically deforming at least the connecting portion 3 from the state in which the engaging end 4a of the elastic engaging piece 4 is engaged with the inserted stud bolt B. It can be pushed and moved inward.

  In the illustrated example, a window hole 6 is formed immediately below the elastic engagement piece 4, and the left and right connecting portions 3 are divided into front and rear connecting pieces 3 a, respectively. Further, since the connecting portion 3 is provided along a virtual line segment that obliquely crosses the central axis x of the stud bolt B to be inserted, the connecting portion 3 is connected when the left and right pressing locations 2b are pressed inward. The portion 3 is elastically deformed in a direction parallel to the center axis x of the stud bolt B with the connecting portion with the base portion 1 and the connecting portion with the side wall portion 2 as the deformation center, and the side wall portion 2 has its lower end at the base of the stud bolt B It is moved inward while moving to the side. At this time, in the illustrated example, the elastic deformation in the direction of narrowing the angle of the inner corner of the connecting portion occurs at the connecting portion between the upper end 2 f of the side wall 2 and the bridging portion 5. As a result of the movement of the side wall portion 2 toward the base side of the stud bolt B, the engagement end 4a of the elastic engagement piece 4 comes out of the groove wall of the screw groove of the screw portion Bb, and the engagement between the two is released. It has come to be.

  In this embodiment, when the side wall portion 2 is moved, the elastic engagement piece 4 is brought into contact with the elastic engagement piece 4 at the base side of the stud bolt B from the engagement end 4a of the elastic engagement piece 4. A contact portion 1 e is provided on the base portion 1. In the illustrated example, the thickness-side end surface 1c of the base 1 facing the side wall portion 2 is used as the contact portion 1e. When the side wall portion 2 is pressed and moved to the innermost side, the contact portion 1e is The elastic engagement piece 4 is in contact with the lower surface of the connecting portion 4f side. (FIG. 5) By this contact, the posture of the elastic engagement piece 4 having the engagement end 4a moved to the position where the engagement with the threaded portion Bb of the stud bolt B is released can be maintained as long as the pressing is continued. I am doing so. In other words, if there is no such contact portion 1e, the elastic engagement piece 4 is once disengaged from the screw portion Bb by the movement of the side wall portion 2 toward the base side of the stud bolt B. As soon as it is moved to the Ba side, it is elastically restored and the threaded portion Bb is re-engaged by changing the location. The elastic return of the piece 4 can be prevented, so that the engaging end 4a changes its position when the clip C moves to the tip Ba side of the stud bolt B while making the pressing, and again engages with the screw portion Bb. It is set so that it does not match.

  As a result, in the clip C according to this embodiment, the operator grasps the clip C with one hand and presses the left and right side walls 2 and 2 of the clip C as described above, while holding the clip C in the stud. By moving to the tip Ba side of the bolt B, it is possible to easily release the clip C from the stud bolt B and separate them. When the pressing is released from the state where the stud bolt B is not completely pulled out from the clip C, the elastic engagement piece 4 is engaged with the threaded portion Bb of the stud bolt B by the elastic return of the connecting portion 3. Return again to.

  In the illustrated example, when the planar member M is a non-deformable member such as a metal panel, the clip C is moved slightly upward by screwing, and then the pressing portion 2b is pressed to form a stud bolt. It will be removed from B. When the planar member M is a deformable member such as a mat, the clip C is removed from the stud bolt B by pressing the pressing portion 2b without screwing the clip C. Can do.

  In the illustrated example, the left and right side wall portions 2 and 2 of the clip C are connected by the bridging portion 5, so that a suitable force is required for the pressing of the side wall portion 2, so that the clip is attached to the stud bolt B. The clamping force of C is kept above a certain level. Such a bridging portion 5 may be of any structure that keeps the fastening force of the clip C at a certain level or more. For example, the bridging portion 5 is provided so as to extend between the front edges or the rear edges of the left and right side wall portions 2 and 2. You can leave it.

  The imparting of this characteristic to the portion to be provided with the elastic deformation characteristic in the clip C according to this embodiment can be easily realized by making the clip C a synthetic resin molded product.
