Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a new structure of attachment members used, for example, when attaching and joining two objects.

2. Description of the Related Art Conventionally, when joining (attaching) two members, a push lever 10 as shown in FIG. 3.4 is used. The two members shown are plate-like members 11 and 12. The push-pull propeller 10 consists of a cylindrical portion 13, a shaft portion 14, and a connecting portion 15 provided as necessary. The cylindrical portion 13 has a flange portion 16 at the upper end and an expanded portion 17 at the lower end. A hole 18' is provided at the center of the flange portion 16 and the cylinder portion 13. The expanded portion 17 has a plurality of grooves 19 formed radially in the center thereof.

The shaft portion 14 is inserted into the center hole 18 of the cylindrical portion 13 and has a flange portion 20 at the upper end.

When members 11 and 12 are joined using rivet lO, members 11.12 are attached to holes 21.2 as shown in Fig. 3.
2. Insert the cylindrical part 13 into 2. Next, the shaft portion 14 is inserted into the center hole 18 from the flange portion 16 side of the cylindrical portion 13. Then, the shaft portion 14 fits into the groove 19 of the expanded portion 17 of the cylindrical portion 13 as shown in FIG.
The expanded portion 17 is expanded outward, and the outer diameter is expanded. As a result, the members 11° and 12 are held between the flange portion 16 and the expanded portion 17.

Problems to be Solved by the Invention According to the above-mentioned bushing rivets, the range of the overall thickness of the members 11 and 12 that can be securely fixed with this is very narrow, so it is necessary to prepare a transfer type of bushing rivets. there were. In addition, the bonding strength was weak, and movement occurred between members 11 and 12 or between Putu 7 Yulipet 1O and members 11° and 12, causing a drawback such as rattling.

The present invention has been proposed in view of these points, and it is possible to considerably widen the range of the thickness etc. of the members to be attached, to use a small number of types, to have strong bonding strength, and to be able to attach with less rattling. The purpose is to provide parts.

Means for Solving the Problems The present invention extends the widened portion 17i of the conventional cylindrical portion 13 and makes the extended widened portion 17 flexible. Then, bend the tip of the extended expanded portion 17 inward to form the cylindrical portion 1.
The structure is such that the hole No. 3 is opened and pulled out in the direction of the flange portion 16.

The bent portion of the action expanding portion is pushed outward to form a loop shape, and this loop portion prevents the cylindrical portion 13 from being pulled out.

Embodiment m1 is a perspective view showing the mounting parts of the first embodiment, and the second figure is a perspective view showing the parts.
The figure is a cross-sectional view of the state in which two plate-like members are connected using the mounting member shown in FIG. 1. Reference numeral 30 denotes a mounting member, which is integrally formed of synthetic resin such as nylon. The mounting members consist of a flange portion 31, a flexible portion 32, and an insertion piece 33. The flange portion 31 is semicircular and has an opening 34 in the center, through which the insertion piece 33 and the flexible portion 32 can be inserted. The flexible portion 32 has one end connected to the center opening edge of the flange portion 31 and the other end extending in a direction away from the flange portion 31 . The outer surface of the flexible portion 32 has sawtooth-like unevenness 35 with the same slope.

The inner surface of the flexible portion 32 has different slopes, with the flange portion 31 side being steeply sloped and short, and the insertion piece 33 side having sawtooth-like unevenness 36 that is gently sloped and long.

The flexible portion 32 has a semicircular cross section. It is also possible that the center opening 34 of the flange portion 31 is similarly provided with unevenness similar to the unevenness 36 on the inner surface of the flexible portion 32.

The insertion piece 33 has one end connected to the lower end of the flexible part 32 via a bendable hinge part 37 having a thin wall part, and the other end has a hook part 38 bent into an L shape.

For this installation, a predetermined number of members 30 are combined. In the case of FIG. 2, two members 30 are used for installation. In FIG. 2, 2fII members 30 are used for mounting, and the center openings 34 of the flange portions 31 are arranged so as to face each other. A pair of attachment members 30.30 has flexible portions 32.32 arranged with their inner surfaces facing each other. Also, a pair of insertion pieces 33.33 are bent from the hinge portion 37.37, overlapped with the inner surface of the flexible portion 32.33, and the free end 38 extends west of the central opening 34 of the flange portion 31.
is projected upwards. In this state, the pair is attached to member 3.
0.30, the plate member 11.12 to be joined is inserted into the hole 21.22 with the flexible portion 32 at the top. Then, the flange portions 31, 31u are abutted against the surface of the plate-like member 110, and the flexible portion 32 is attached to and protrudes from the back surface of the plate-like member 12 through the holes 21 and 224. Next, the insertion piece 33.
33 upward in the direction of arrow 39. Then, the flexible part 32.32 is reattached from the side end of the insertion piece 33.33 to the hole 2.
1, 22, and is pulled out through the central opening 34 of the flange part and upwardly of the flange part 1. At this time, the flexible portion 32.
32 is a loop portion 40.4 on the back side of the plate member 12.
0 is formed and expanded outward. and flexible section 32
．． 32 unevenness 35.35 engage with each other, and unevenness 36
．． 36 interlock with each other. In this way, the flexible part 32.32
The flange portion 31 does not slip due to the engagement of the projections and depressions 35 and 35, and the engagement of the projections and depressions 36 and 36 prevents the flange portion 31 from slipping.
．． The loop part 40.4 facilitates movement in the 31 direction.
Makes movement in the 0 direction difficult.

By these, the flexible parts 32, 32,
．． 33 side is easy to move in the direction of arrow 39, but difficult to move in the opposite direction to arrow 39, and loop portion 40.4
1. In this way, after the flexible part 32.32 is inserted into the mounting hole 21.22, it is folded back and inserted into the mounting hole 21.22 again. , the plate member ti is formed by the flange portion 31°31 and the loop portion 40.40.
, 12 are clamped and combined.

Effect of the invention .

The loop portion 40.40 is attached to the plate member 11.
The plate member 11.1 is formed at a position corresponding to the thickness of the plate member 11.1.
2 can be accommodated to a considerable extent. Also, the loop part 40
．． 40 can change the outward expansion tt by changing the amount by which the flexible part 32, 32 is pulled out from the flange part 31, and the mounting can accommodate changes in the hole 21, 22 to a considerable extent, and the connection It is possible to make power reliable and stable. In this way, the attachment can be adapted to a considerable range even if the thickness of the member and the hole are changed, and it has the effect of providing a reliable and strong joining member without any looseness.

In the above embodiments, the attachment of the members 30 was explained using two metals, but it is also possible to connect one or more members by using metal. Further, for attachment, the member 30 may be pre-formed into a shape in which two pieces are combined into one body as shown in FIG. In this case, the seven flange portions 31.31 are coupled to each other, and a plurality of flexible portions 32.32 are separated and protruded from the lower surface of the flange portion 31.31.
