As shown in FIG. 2, the attachment portion 2 includes a substantially disk-shaped stabilizer 7 and a locking portion 5 that protrudes perpendicularly to the center of the stabilizer 7. The stabilizer 7 of the attachment part 2 is provided immediately above the disk 9 on the assembly part 3.
The stabilizer 7 has a substantially disk shape that becomes thinner toward the outer peripheral direction, and is formed in a concave mortar shape. The stabilizer 7 has flexibility, and when the clip 1 is attached to the attached member 31, the outer edge thereof is in close contact with the attachment surface of the attached member 31.
The central portion of the stabilizer 7 is a flat plate-like portion on which the locking portion 5 is directly provided, and this corresponds to the “substrate” of the present invention.
[0011]
The locking portion 5 has a substantially cylindrical shape with a sharp upper end, and has a substantially plate-like support column 13 provided perpendicularly to the approximate center of the stabilizer 7, and a substantially conical shape at the upper end of the support column 13. A tapered portion 14 is provided. The support column 13 is positioned substantially on the diameter of the locking portion 5, and both side ends thereof form the outer peripheral surface of the locking portion 5. In addition, two locking pieces 15 are suspended from the lower portion of the side surface of the taper portion 14 so as to be substantially parallel to the support column portion 13, and the lower end thereof reaches the upper surface of the stabilizer 7. As shown in FIG. 4, each locking piece 15 is provided at a distance from the support column 13 so that each locking piece 15 can bend inside the locking portion 5. . In addition, the some recessed part on the taper part 14 is the meat removal part provided in order to reduce the weight of a clip.
[0012]
As shown in FIG. 4, one side end portion of the support column 13 is provided wide and formed on the fixed piece 16. The fixed piece 16 is thick and does not have flexibility. On the other hand, the two locking pieces 15 are thin and formed to have flexibility. The outer peripheral surfaces of the fixed piece 16 and the respective locking pieces 15 have the same shape, and are formed so as to gradually spread downward in the substantially radial direction of the locking portion 5 as shown in FIGS. The locking shoulders 16a and 15a are provided at positions slightly higher than the outer edge of the stabilizer 7. FIG. 5 shows a view of the clip 1 as viewed from above. The locking shoulders 16 a and 15 a protrude outwardly larger than the inner diameter of the locking hole 32 of the mounted member 31. From the lower ends of the locking shoulders 16a and 15a, the entire locking portion 5 is formed in a substantially columnar shape having a radius substantially equal to the locking hole 32 through an attenuation portion whose radius gradually decreases.
[0013]
As shown in FIG. 6, the side end portion on the opposite side of the column portion 13 has a lower end of the tapered portion 14 such that the locking shoulder 16 a portion of the fixed piece 16 is equal to or smaller than the diameter of the locking hole 32 of the mounted member 31. To the portion reaching the stabilizer 7 is formed in a concave shape.
[0014]
Further, as shown in FIG. 4, the two locking pieces 15 are extended along the entire circumference of the locking portion 5 toward the side end where the fixed piece 16 of the support column 13 is not provided. Part 18. Furthermore, each latching piece 15 is formed by extending the latching shoulder 15a in the lateral direction at both side ends. By providing the fixing pieces 16 wide and forming the extension portions 18 and the extension portions on each locking piece 15, the outer peripheral portion of the locking portion 5 becomes larger, and the peripheral edge of the locking hole 32 of the mounted member 31, that is, The part which contacts the edge of the hole of the locking hole 32 in the back surface of the surface close to the stabilizer 7 of the clip 1 increases.
[0015]
Next, the procedure for attaching the attachment member 21 to the attachment member 31 using this clip will be described.
As shown in the lower part of FIG. 3, the clip 1 is assembled to the mounting member 21, and the locking portion 5 of the mounting portion 2 of the clip 1 is inserted into the locking hole 32 of the mounted member 31. When a portion larger than the locking hole 32 of the fixing piece 16 and the locking piece 15 hits the end edge of the locking hole 32, it is pushed by applying more force. At this time, the entire clip 1 moves in the direction in which the support column 13 is formed in a concave shape with respect to the locking hole 32, and the fixing piece 16 can be inserted into the locking hole 32. Further, as shown in FIGS. 7 and 3, each of the two locking pieces 15 is bent toward the inner side of the locking portion 5 to reduce the radius, and the locking portion 5 can be inserted into the locking hole 32. it can. FIG. 8 shows a state in which the clip 1 is completely attached.
Further, the clip 1 can be pulled out from the locking hole 32 by pulling with a force stronger than that at the time of attachment.
[0016]
According to the clip 1 of the present embodiment, since the two locking pieces 15 are fixed to the stabilizer 7, the locking portion 5 has high rigidity and is not likely to wobble. In addition, since both side ends of the support column 13 form the outer peripheral surface of the locking portion 5 at two places, and one side end thereof is formed on the fixed piece 16, the rigidity of the locking portion 5 as a whole is increased. Becomes larger, and the clip 1 is more firmly engaged by the mounted member 31. Further, by providing the locking piece 15 with the extension portion 18 and the extension portion, and further providing the fixing piece 16 with a wide width to increase the outer surface area, the area contacting the peripheral edge of the locking hole 32 of the mounted member 31 at the time of mounting. The mounting member 21 can be attached to the mounted member 31 more stably. For this reason, the clip 1 of the present embodiment is less likely to be tilted or wobble even when receiving a force from various directions in the attached state, and can fix the attachment member 21 stably.
[0017]
The clip according to the present invention is not limited to the present embodiment.
The number and shape of the locking pieces 15 of the locking portion 5 are not limited to the present embodiment. The number of the locking pieces 15 may be at least one. The number is preferably about 2 to 5.
Further, the number of the fixing pieces 16 may not be one, but may be two or three. When the number of the fixing pieces 16 increases, it is easy to suppress wobbling at the time of engagement, which is preferable, but a strong force for engagement / disengagement is required.
[0018]
The shapes of the locking piece 15 and the fixing piece 16 are not limited to the present embodiment. The shape having the locking shoulders 15a and 16a is preferable. However, when the column portion 13 or the fixing piece 16 is present at a position facing the locking piece 15 or the fixing piece 16, the locking shoulder is not provided or the concave shape is formed. Can be formed.
[0019]
Moreover, the latching piece 15 should just have the flexibility of the extent which the clip 1 can be engaged / disengaged by human force. In order to suppress the wobbling of the clip 1, it is preferable to have a smaller flexibility in this range. The flexibility of the locking piece 15 can be controlled by changing the thickness or material.
[0020]
Moreover, the shape of the support | pillar part 13 is not limited to this Embodiment. For example, a fan shape centered on the center of the stabilizer 7 may be used. It is sufficient that the support column 13 forms at least a part of the outer peripheral surface of the locking unit 5. Providing the support column 13 in this manner increases the rigidity of the locking portion 5, so that wobbling of the clip 1 can be suppressed. Moreover, since the outer peripheral surface of the latching | locking part 5 is formed in two places like this Embodiment, since rigidity becomes higher, it is preferable.
Moreover, the stabilizer 7 of the assembly part 3 and the attachment part 2 can have an arbitrary shape.
[0021]
