  The clip described above can be temporarily assembled depending on the insertion amount of the male member relative to the female member, or can be switched from the leg diameter expanded state to the non-diameter expanded state. It was easy to receive. That is, as a structural feature, since the male member and the female member are separate bodies, they are easily lost and handling and provisional assembly operations become complicated. Further, since the male member is inserted into the opening of the female member in the vertical direction, the amount of protrusion to the panel lower surface side becomes large, and it may become impossible to apply due to the relationship with the space on the panel lower surface side.

  An object of the present invention is to eliminate the above-described problems and to make a structure excellent in handling and provisional operability. Another object is to make it easy to suppress the amount of protrusion to the lower surface side of the panel (including a plate, a flange portion of an article, and the like) by maintaining the fixing force and fastening force by the clip.

  In order to achieve the above object, the present invention comprises a female member and a male member inserted into an opening of the female member, the female member protruding from a collar part, a bottom surface of the collar part, and the leg part. A clip having a diameter-expansion projection that is provided on the inner surface of the female member and abuts against the male member, the male member being connected to the flange portion via a hinge portion, and an opening portion of the female member And the leg portion is expanded in diameter by pressing the corresponding portion against the protrusion.

The present invention as described above is more preferably embodied as in claims 2-5. That is,
(A) The male member is inserted into the opening of the female member and further pushed in from the state in which the leg portion has been enlarged, so that the convex portion enters and the leg portion is brought into the original non-expanded state. It is the structure which has the hollow part which can be switched to an expanded diameter state (Claim 2).
(B) The male member is configured to be inserted into the opening of the female member by being rotated with the hinge portion as a fulcrum.
(C) The male member and the female member are one of a concave portion and a convex portion for holding a temporarily assembled state that are releasably engaged with each other in a state in which a tip portion of the male member is inserted into the opening of the female member. (Claim 4). In addition, in this structure, the aspect of a male member side convex part and a female member side convex part, and the aspect of a male member side convex part and a female member side concave part are included as a recessed part and convex part for temporary assembly state holding | maintenance.
(D) The male member and the female member each have one of a concave portion and a convex portion for maintaining a diameter-enlarged state that are releasably engaged with each other in the diameter-extended state of the leg portion. Claim 5). In addition, in this structure, the aspect of a male member side convex part and a female member side convex part, the aspect of a male member side convex part, and a female member side concave part are included as a recessed part and convex part for an enlarged diameter state maintenance.

  According to the first aspect of the present invention, since the male member is connected to the collar portion of the female member via the hinge portion, the male member and the female member can be transported and stored as an integrated product, thereby improving usability. Further, since the male member is moved through the hinge portion and inserted into the opening of the female member, the insertion operability, that is, the operability for switching to the temporary assembling property and the leg diameter enlarged state can be satisfactorily performed.

  In the invention of claim 2, the male member is further pushed into the female member from the diameter-enlarged state of the leg portion, so that the convex portion for expanding the diameter is relieved in the recess and the leg portion is switched to the original non-diameter-enlarged state. The panel can be unwrapped and fastened with a simple operation. Further, in the invention of claim 3, the male member is rotationally operated with the hinge portion as a fulcrum and is inserted into the opening of the female member. For example, the male member is switched from the enlarged diameter state of the leg portion to the non-expanded state. Compared to the conventional structure in which members are pushed in vertically, the amount of protrusion to the lower surface of the panel can be suppressed, and application restrictions can be eliminated.

  In the invention of claim 4, since the male member and the female member are held in the temporary assembly state by the engagement of the temporary assembly holding concave portion and the convex portion, the operability and the switching operability from the temporary assembly state to the leg diameter enlarged state are achieved. Can be performed better. Further, in the invention of claim 5, the use state in which the male member and the female member fix or fasten the panels together by the engagement of the expanded diameter holding concave portion and the convex portion can be stably held.

  Hereinafter, the best mode of the present invention will be described with reference to the drawings. 1 to 4 show a state immediately before the clip is formed, FIG. 5 shows a temporary assembly operation when the male member is temporarily assembled to the female member in the clip, and FIG. 6 shows a state where the leg portion is expanded in diameter. FIG. 7 shows a non-expanded state.

The clip 4 in the (structure) form is used when fastening a plurality of panels 5 and 6 as shown in FIGS. 1 and 6 or attaching the upper panel 6 to the lower panel 5. It has the female member 1 and the male member 2 inserted in the opening part 11 of this female member, and consists of the resin molding which the female member 1 and the male member 2 formed integrally through the hinge part 3. FIG.

  The female member 1 has a substantially cylindrical shape, and includes a flange portion 10, a plurality of leg portions 15 projecting from the bottom surface of the flange portion, and a protrusion 17 for expanding the diameter that is provided on the inner surface of each leg portion and contacts the male member 2. have. The flange portion 10 is the largest outer diameter portion, and is formed in a taper 12 that decreases in diameter as it goes down the upper inner edge portion of the opening portion 11. The opening 11 is provided with a recess 13a and a notch 13b facing each other. As shown in FIG. 5A, the recess 13a protrudes from the rear surface of the recess toward the inside of the opening 11. The convex portion 14 is an engaging portion that serves both for holding the temporary assembly state and for holding the expanded diameter state. The notch 13b is a part of the flange portion 10 lacking a predetermined depth, and the hinge portion 3 is formed so as to protrude outward therefrom. In addition, the code | symbol 10a is the cavity part 10a notched to the upper side from the lower surface of the collar part 10. FIG.

  The leg portion 15 has a two-piece structure, protrudes from the lower surface of the flange portion, and faces each other. The legs are provided with an interval corresponding to the recess 13a or the notch 13b. Each leg portion 15 is formed with a taper 16 having a diameter that decreases toward the lower end of the outer surface, and has a diameter-expansion projection 17 provided on the inner side. Each protrusion 17 is in the shape of a longitudinal rib on the leg inner surface 18 and extending upward from the tip of the leg.

  On the other hand, the male member 2 is provided in a state where the base portion is connected to the tip of the hinge portion 3 protruding from the flange-side notch portion 13b, and the female member 2 is rotated by using the hinge portion 3 as a fulcrum. 1 opening 11. More specifically, the male member 2 has a plate thickness slightly smaller than the width of the recess 13a or the notch 13b, and is a schematic piece defined by the side surfaces 20, the inner end surface 22, the outer end surface 23, the lower end surface 24, and the upper end surface 25. The lower side of the inner end face 22 is integrated with the hinge portion 3 in the form immediately before being formed.

  The both side surfaces 20 are provided with relief portions 21 which are on the upper side and are thinned from the outer end surface 23 toward the inner end surface 22. The outer end surface 23 is an arc surface. The outer end surface 23 is provided with a temporary assembly state holding recess 26 that communicates with the relief portions 21 on both sides and an enlarged diameter holding recess 27 that is positioned below the recess 26. The lower end surface 24 is sized to fit into the recess 13a, the opening 11, and the notch 13b. The upper end surface 25 is a small surface because the outer end surface 23 is close to the inner end surface 22.

(Operation) Next, the operational characteristics of the clip 4 will be described in detail.
(A) First, even if the above clip 4 is conveyed in the form at the time of molding, since the female member 1 and the male member 2 are integrated via the hinge portion 3, it is easier to handle than the conventional clip. It has excellent handling properties such as eliminating the problem of losing one. Further, since the female / male members 1 and 2 are inserted into the opening 11 of the female member 1 when the male member 2 is rotated about the hinge portion 3 as a fulcrum, it is easy to be in a temporarily assembled state described below. It is also excellent in that it can be made compact in the temporary assembly state.

(A) That is, when the male member 2 is rotated toward the female member side opening portion 11 with the hinge portion 3 as a fulcrum as shown in FIG. As shown in (b), the concave portion 26 is engaged with the opening-side convex portion 14 when the tip end side of the male member 2 is inserted into the opening portion 11 by a predetermined amount. FIG. 5B shows a temporarily assembled state in which the male member 2 is temporarily assembled to the female member 1 in this manner. In this temporarily assembled state, the male member 2 is held at the insertion position with respect to the female member 1 by the engagement of the concave portion 26 and the convex portion 14. In this operation process, when the distal end side of the male member 2 abuts against the convex portion 14 and elastically displaces the convex portion 14 toward the cavity portion 10a, the concave portion 26 faces the convex portion 14 when being inserted into the opening portion 11 a little. The engaging force is engaged with a clicking sound by the restoring force of the convex portion 14.

(C) FIG. 6 shows a state in which the male member 2 is further pushed in and the panels 5 and 6 are overlapped with each other or the leg portion is expanded in diameter with the panel 6 fastened to the panel 5. That is, in this structure, when the male member 2 is further inserted (pressed) from the temporarily assembled state, the concave portion 26 is disengaged from the convex portion 14, and then the hinge portion 3 is used as a fulcrum to further open the opening portion 11. Is rotated to. In terms of design, the male member 2 is switched to the diameter-enlarged state of the leg portion by inserting the male member-side lower end surface 24 into the female member 1 until it is substantially flush with the flange portion 10. In this operation process, after the front end side of the male member 2 is slid along the inner surfaces of the both leg portions 15, the male member 2 is pushed between the projections 17 and 17, and the both leg portions 15 increase the distance between the projections 17 and 17. It is elastically displaced in the direction of expanding the diameter. In this structure, when the leg portion diameter-expanded state is reached, the male member-side concave portion 27 faces the convex portion 14 and engages with a clicking sound by the restoring force of the convex portion 14, whereby the leg diameter-expanded state is achieved. It is held so that it is not inadvertently released. Reference numerals 5 a and 6 a are attachment holes provided in the panels 5 and 6 for inserting the leg portions 15 of the female member 1.

(D) FIG. 7 shows a non-expanded state in which the male member 2 is further pushed in from the expanded-diameter state of the leg portion to make the female member-side leg portion 15 the original non-expanded diameter (original shape). That is, in this structure, when the male member 2 is further inserted (pressed) from the diameter-enlarged state of the leg portion, after the concave portion 27 is disengaged from the convex portion 14, the hinge portion 3 is further used as a fulcrum. 11 to rotate. In terms of design, when the male member 2 is inserted into the female member 1 until the male member-side lower end surface 24 is slightly inserted into the opening 11, the respective recessed portions 21 of the both side surfaces 20 are fitted with the corresponding protrusions 17. By releasing the protrusion 17 into the recess 21, the load for expanding the leg portion is released so that the original shape can be restored, whereby the panels 5 and 6 are superposed or the panel 6 is fastened to the panel 5. It is solved. In the above clip structure, the male member 2 rotates to the female member side opening 11 with the hinge portion 3 as a fulcrum, so that the provisional assembly state, the provisional assembly state to the leg portion diameter expansion state, and the leg portion diameter expansion state to the non-diameter expansion state. Since each state can be switched, as compared with the conventional structure in which the male member is pushed in the vertical direction as in Patent Document 1, it is possible to reduce the amount of protrusion to the lower surface side of the panel, and it is possible to eliminate restrictions on use. Moreover, in this clip structure, since the recessed part 21 into which the diameter-expansion protrusion 17 enters can be formed on both side surfaces 20 of the male member, the recessed part (the recessed part corresponding to the recessed part 21 of the present application) is pivoted as in Patent Document 1. There is no risk of losing rigidity as compared with the structure formed in the above.

In addition, the clip of this invention should just be equipped with the structure specified by Claim 1, and a detail can be variously changed as needed. Of course, the use is not limited to the example of the panel given in the form, and is arbitrary.
