６，２７は強固に固定される。 Now, the fastener 1 of this example is made of a synthetic resin or the like that removably fixes plate-like members 26 and 27 having mounting holes 26a and 27a formed therethrough.
consists of a male member 2 and a female member 11, and the male member 2
On the lower surface of the head 3, there is a locking shaft having a locking block 6 having a large diameter d1 and a substantially warhead shape at the lower end, and a locking portion 7 protruding laterally at a predetermined position h1 on the side of the head 3. 4 are vertically provided, and a hole 13 including an insertion hole 14 into which the locking shaft 4 can be inserted is provided in the base plate 12 of the female member 11, and a hole 13 is provided along the corresponding hole edge 15 of the insertion hole 14. A guide piece 17 that can be inserted into the mounting holes 26a, 27a is provided between the mutual ends of the guide piece 17, the upper end facing the insertion hole 14, and insertable into the mounting holes 26a, 27a. A circular arc surface 2 with a diameter D2 that has a locking protrusion 25 projecting inward at the same end and inserts and guides the locking block 6 on the inner surface 23.
4a, and a pair of locking legs 20 having an inclined surface 24b that slopes downward toward the inner side on the lower side continuous with the arcuate surface 24a are swingably linked via a hinge portion 19. That is. Therefore, before joining the two plate-shaped members, the male member 2 is inserted into the hole 14 with the split surface 10 of the locking shaft 4 aligned with the hole edge 15 of the insertion hole 14 of the female member 11. When the locking block 6 is inserted further, the tip of the locking block 6 comes into contact with the locking protrusion 25 of the locking leg 20, and when the locking leg 20 is further inserted, the locking leg 20 swings about the hinge portion 19 in the direction of the broken line arrow shown in the figure due to the elastic deformation of the hinge portion 19. be moved. When the locking block 6 passes the locking protrusion 25, the hinge portion 19 is elastically restored and the locking leg 20 is swung in the direction of the solid arrow to return to its original state. As a result, as shown in the figure, the locking protrusion 25 is engaged with the locking block 20, and the male member 2 is prevented from coming off, thereby locking both members 2, 1.
1 is temporarily connected. After that, when the locking leg 20 and the guide piece 17 are inserted into the aligned mounting holes 26a and 27a in this temporarily fixed state and the male member 2 is pressed, the locking block 6 provided at the tip of the locking shaft 4 is released. It descends guided by the arcuate surface 24a of the inner surface 23, and when pressed further, it is guided by the inclined surface 24a,
As a result, the lower end sides of the left and right locking legs 20 are spread apart and elastically displaced into a substantially V-shape via the hinge portion 19, and both locking legs 20
At the upper end, the locking part 7 is brought into contact with the locking protrusion 25, and when the male member 2 is further pressed, the left and right locking legs 20 are connected to the locking part 7, the locking block 6, and the mounting holes 26a, 27a. When the locking portion 7 passes through the locking protrusion 25, the upper end side of the locking leg 20 elastically restores itself to the locking protrusion 2.
5 is engaged with the locking surface 8, and at the same time, the head 3 is brought into contact with the base plate 12. In this state, the lower end side of the locking leg 20 is elastically displaced outward below the mounting holes 26a and 27a, and the locking portion 7 is engaged with the locking protrusion 25 and prevented from coming off, so that both plates shaped member 2
6 and 27 are firmly fixed.

ができる。 Next, to release the fixation of the plate-like members 26 and 27, hold the head 3 of the male member 2 and pull it upward with a little strong force to release the engagement between the locking part 7 and the locking protrusion 25. When released, the locking shaft 4 is pulled upward, and the locking block 6 pushes outward the portions of the arcuate surfaces 24a of the left and right locking legs 20 that have the largest amount of elastic deformation, thereby causing the opening and expansion. Locking leg 2
The lower end side of 0 is closed inward and restored to its original state, and when the head 3 is grabbed and pulled out, the male member 2 and female member 11 can be removed as one without separating, forming a plate-like member. The fixation of 26 and 27 can be released.

る。 In this way, according to the fastener of this example, the female member 11 and the male member 2 are connected in a male-female manner, and the plate-like member 26,
27 and economical locking leg 2 after a long period of time.
Even if a creep phenomenon occurs in 0, by pulling out the male member 2 and releasing the engagement between the locking part 7 and the locking protrusion 25, the left and right parts can be removed between the mounting holes 26, 27 and the locking block 6. Since the portion of the arcuate surface 24a of the locking leg 20 having the largest amount of elastic deformation is forcibly corrected, the portion of the inclined surface 24b that is continuous thereto can also be restored to its original state, making release easy. Therefore, when reusing the plate members 26 and 27, the plate members 26 and 27 can be easily inserted into the mounting holes 26a and 27a without any problems, and the plate members 26 and 27 can be securely fixed. In addition, since the male and female members 2 and 11 are unlikely to come off after they are temporarily joined, there are many advantages such as ease of parts management by temporarily joining them in advance.

It is possible to fix a larger number of sheets. Further, the shapes of the head 3 of the male member 2 and the base plate 12 of the female member 11 are not limited to circular shapes, and may be of other shapes.

実用性に優れた考案である。(Effects of the invention) The present invention is a fastener made of synthetic resin or the like that removably fixes a plurality of plate-like members with mounting holes extending through them, and the fastener consists of a male member and a female member. , the male member has a locking shaft having a large-diameter, approximately warhead-shaped locking block at the lower end thereof and a locking portion protruding laterally at a predetermined position near the substrate, which is vertically disposed on the lower surface of the head of the male member. Further, an insertion hole into which the locking shaft can be inserted is provided in the base plate of the female member, and a guide piece is provided along a corresponding hole edge of the insertion hole so that the insertion hole can be inserted into the mounting hole. The guide piece can be inserted into the mounting hole between the mutual ends thereof, and has an upper end facing the insertion hole and a locking protrusion projecting inward at the same end, and an inner surface of the guide piece. A pair of locking legs having a circular arc surface for guiding the insertion of the locking block, and a lower side continuous with the circular arc surface having an inclined surface that slopes downwardly toward the inner side are swingable through a hinge portion. Due to the movably connected structure, the female member and the male member are connected in a male-female manner to fix a plurality of plate-like members, and even if creep phenomenon occurs in the locking leg over a long period of time, it is economical. By pulling out the male member and disengaging the locking portion from the locking protrusion, the arcuate portion of the left and right locking legs with the largest amount of elastic deformation is forced between the mounting hole and the locking block. Since the part of the inclined surface that follows this can be restored to its original state, it can be easily released, and when reusing it, it can be inserted into the mounting hole without any problems. This can be easily done and the plate-shaped member can be securely fixed. Furthermore, since the male and female members are unlikely to come off after they are temporarily joined, it is easy to manage the parts by temporarily joining them in advance, so this is an extremely practical device as a fastener.
