Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fastener for fixing a member to be attached to a mounting member.

[Conventional technology]

Conventionally, as this kind of Fuasuna, Tokuhei 1-
There is a clip as shown in FIG. 7 disclosed in Japanese Patent No. 48406. In other words, 1 in the figure is a clip main body, in which a main leg 3 hangs down from the center of the lower surface of a disc-shaped top part 2, and a pair of elastic arms 4, 4 having elastic force extend diagonally upward from both sides of the lower end. It is growing,
A through hole 6 is formed in the attached member 5A and the attachment member 5B to be fixed by the clip body 1.

Therefore, when attaching the attached member 5A to the attaching member 5B, when the lower end of the main leg 3 of the clip body 1 is pushed into the common through hole 6, the left and right arms 4, 4 are elastically deformed inwardly from each other. However, when the upper ends of the arms 4, 4 protrude downward from the through hole 6, the left and right arms 4, 4 are restored. the result,
Both members 5
A and 5B are sandwiched and fixed from above and below.

[Problem that the invention attempts to solve]

However, in the conventional clip as described above, the pair of arms 4, 4 have elastic force in the left and right direction, but not in the vertical direction, so the distance between the top surface part 2 and the upper end of the arms 4, 4 is is always constant.

Therefore, if the total thickness of both members 5A, 5B is thinner than the distance between the top surface portion 2 and the upper end of arm 4, wobbling will occur in the vertical direction, and conversely, the thickness of both members 5A, 5B If the thickness was thicker than this, it would be impossible to fix.

In addition, the through holes 6 formed in both members 5A and 5b are
Since the main leg 3 and both arms 4 need to be formed in a size that allows them to be inserted, the main leg 3 and both arms 4 must be formed in a size that allows them to be inserted between the clip body 1 and both members 5A and 5B, or between the clip body 1 and both members 5A and 5B.
Another problem was that A and 5B moved horizontally relative to each other.

Furthermore, when removing the clip main body 1 from both members 5A, 5B, both arms 4, 4 must be compressed to the main leg 3 side. In cases where it is not possible to access the inside of the clip, there are problems in that the clip cannot be removed without destroying the clip body 1.

[Means for solving the problems] The present invention was developed to solve the problems of the conventional methods as described above. The purpose of this is to provide a device that does not move in the horizontal direction and can be removed from the insertion direction. a head equipped with a curved elastic section curved in an arc shape; a pair of legs that hang down from the center of the lower surface of the head and have elastic force in the left-right direction;
The fastener is characterized by comprising hooks formed on the outer sides of the distal ends of both legs.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 6. In addition, FIG. 1 is a perspective view of a fastener and a fixing member according to the present invention, FIG. 2 is a partially cutaway front view showing a state in which the fixing member is fixed by the same fastener, and FIG. 3 is a bottom view of the fastener. , FIG. 4 is a front view of the fixing member being fixed with the fastener, FIG. 5 is a front view of the fixing member being removed from the fixing member, and FIG. 6 is a front view of another embodiment in the middle of fixing the fixing member with the fastener. It is a front view.

In the figure, 1 is the fastener body, and 2 is its head. The head 2 is formed of a band-like plate made of an elastic material such as synthetic resin, and has both ends curved downward and inward in an arc shape to have elastic force in the vertical and horizontal directions. Elastic parts 3A, 3B
is formed.

Further, in the center of the lower surface of the head 2, a vertical groove 4 is provided.
A pair of leg portions 5A, 5B that are open at the tips thereof hang down, and hooks 6A, 6B are formed on the outside of the tip portions of both leg portions 5A, 5B, respectively. Then, the tips of both leg portions 5A, 5B and the hook 6
The outer sides of the step portions 7 of the hooks A and 6B are each formed in an arc shape, and the outer circumferential surfaces 8 of the hooks 6A and 6B are formed into an arc-shaped tapered surface that tapers toward the tip.

9A is the member to be attached, and 9B is the attachment member (hereinafter referred to as
(both are referred to as mounting members), and both mounting members 9A, 9
Through-holes 10 are formed in each of the holes B, each having a radius of curvature that is approximately the same as the radius of curvature of the outer circumferential surfaces of the leg portions 5A and 5B during normal operation.

Therefore, when fixing both the mounting members 9A and 9B with the fastener body 1, as shown in FIG.
When the tips of the hooks 6A, 6B are inserted and the head 2 is pressed, the legs 5A, 5B are elastically deformed so as to approach each other and are inserted into the through hole 10.

Then, when the hooks 6A and 6B pass through the through hole 10 and protrude from the lower surface of the mounting member 9B, the legs 5A and 5B are restored to their original state, respectively, as shown in FIG.
The stepped portions 7 of the hooks 6A, 6B engage with the periphery of the through hole 10 on the lower surface of the mounting member 9B.

As a result, both mounting members 9A and 9B are attached to the head 2.
It is elastically clamped and fixed from above and below by the free ends of the curved elastic parts 3A, 3B or the peripheral edges thereof and the stepped parts 7 of the hooks 6A, 6B.

Here, if the total thickness (height) of both mounting members 9A, 9B is thicker than the distance between the free ends of curved elastic parts 3A, 3B and the stepped portions 7 of hooks 6A, 6B, The bending elastic parts 3A and 3B are elastically deformed.

That is, as shown by the imaginary lines in FIG. 2, the free ends of the bending elastic parts 3A and 3B are elastically deformed inwardly and upwardly, and both the mounting members 9A and 9B are more strongly clamped and fixed. .

Next, when removing the fastener main body 1 from the mounting members 9A, 9B, as shown in FIG. After the outer peripheral edges of the hooks 6A and 6B are deformed to a size smaller than that of the through hole 10, the head 2 may be pulled upward.

In addition, in the above embodiment, the mounting members 9A, 9B
In this case, the radius of the through hole 10 of the mounting members 9A, 9 was almost the same as the radius of curvature of the outer circumferential surface of both the legs 5A, 5B during normal operation, but the radius of the through hole 10 of the mounting members 9A, 9 was approximately the same as the radius of curvature of the outer peripheral surface of the legs 5A, 5B during normal operation. If the radius of curvature is smaller than the radius of curvature, as shown in FIG.
The legs 5A and 5B are brought closer to each other via the
The outer diameters of both hooks 6A, 6B may be made smaller than the diameter of the through-hole 10, and then the hooks may be pushed into the through-holes 10 of the mounting members 9A, 9B.

[Effect of idea]

As described above, the fastener according to the present invention includes a head portion including a curved elastic portion formed by bending both end edges of a band-like plate body downward and inward in an arc shape, and a head portion extending from the center of the lower surface of the head. It is composed of a pair of legs that hang down and have elasticity in the left and right directions, and hooks formed on the outside of the tips of both legs, so when both mounting members are fixed, the head does not move vertically. Since it is elastically deformed, it is securely fixed in a tight state regardless of its total thickness. Further, since both the legs are restored outwardly within the through-holes of both attachment members, there is no possibility of horizontal movement between the fastener main body and both attachment members, and between both attachment members.

Furthermore, when removing the fastener main body from both mounting members, the legs can be brought closer together by pressing the head from the left and right, and the fastener main body can be pulled out from above, making it easy to remove from the mounting direction without damaging the fastener. can be removed. Therefore, there are various effects such as improved workability and economical reuse.
