Further, the one-sided member 1 is not limited to the above-mentioned washer, and is made of a material such as a plate material or a cylindrical material having through holes 3 which are appropriately used in various industries as shown in FIG. Although not shown in the figure, it can also be used as a constituent material, and a structural material such as metal fittings or a building, its constituent parts such as accessory parts, a box-shaped case, furniture, etc., or metal, non-ferrous metal It is used in a wide range of fields such as packing made of plastic or synthetic resin.

The other member 2 is a hexagon nut as shown in FIG. 3 (a), a cap nut as shown in FIG. 3 (b), a square nut as shown in FIG. 3 (c). 3 (d)
It is adopted in various female screw bodies such as a butterfly nut as shown in FIG.
It is formed larger than the outer diameter of the screw portion 5 because it is screwed on.

The inner peripheral portion of the protrusion 4 is provided with a threaded portion 5a formed by extending the female threaded portion 5. As shown in FIG. Even if the through hole 3 of the member 1 is formed to have a slightly smaller diameter, a predetermined thin portion 5b is formed on the outer periphery of the protrusion 4 at the valley portion of the screw portion 5a. When pushed into the body 4,
The thin portion 5b is curved inward to adapt to the diameter of the through hole.
Can be inserted.

Furthermore, the other member 2 can be used for various washers as shown in FIGS. Of the washer 2 is formed so as to be larger than the inner diameter of the through hole 6 of the washer 2 and protrudes, and the inner circumference thereof is substantially matched with the inner diameter of the through hole 6 of the washer 2.

Further, as shown in FIG. 6, the other member 2 is also used as a component of articles such as a plate material having a through hole 6 appropriately used in various industries or a cylindrical material. Although not shown, although not shown, structures such as metal fittings and structures, and components such as accessory parts thereof, box-shaped cases, furniture and the like, or metal, non-ferrous metal, or It is used in a wide range of fields such as packing made of synthetic resin.

The protrusion 4 of the other member 2 is
As shown in FIG. 7 (a), it is provided so as to project perpendicularly to one side surface of the other member 2, or as shown in FIG. It is formed into a completely tapered shape.

By combining the one member 1 and the other member 2 in each of the above-described embodiments, an arbitrary coupling set A is formed according to the use condition, one example of which is shown in FIG. 1 (a) to (e), one member 1 in (d) is a coil-shaped spring. (Note that the present invention is not limited to this example.) In the formation of this combined set A,
The through hole 3 of the one member 1 and the protruding body 4 of the other member 2 are superposed so as to coincide with each other, and one or both of them are pressed to engage the through hole 3 and the protruding body 4. ,
An integral connection is achieved by fitting and friction between the two having a predetermined insertion resistance.

At the time of transportation of this combination set A, both members 1,
Since the two are sufficiently coupled, even if vibration, impact, or the like occurs, the two are not separated from each other and a reliable coupled state is maintained.

In use, this combined set A
Is a nut 2 and a spring washer 2 as shown in FIG. 1 (a), in the temporarily fixed state, as shown in FIG. The mounting members 9 and 10 can be screwed to the screw portion 8 with the mounting members 9 and 10 interposed therebetween.

FIGS. 9 and 10 show an example in which the through hole 3 of the one member 1 is deformed to form a narrow hole 9 narrower than the through hole 3.

The means for carrying out this deformation processing is carried out on the peripheral portion of the through hole 3 by means of roller clamping, pressing, punching, vise, or any other pressing or pressing means (not shown).

This deformation processing is performed by referring to FIGS. 9 and 10 (a), (b).
Curved, distorted or bent, as shown in Figure 10, or
As shown in (c), twist, distortion, etc., as shown in Fig. 10 (d), corrugated processing, or as shown in Fig. 10 (e), projection processing by hammering. As a result, the locking edge b is formed at one or more positions on the peripheral edge of the through hole 3 of the one member 1.

Deformation by bending, straining or bending is performed symmetrically with respect to the center line s of the through hole 3 in the one member 1 in FIG. 9 (a), or as shown in FIG. 9 (b). As shown, it is applied at an eccentric position of a distance h from the center line s, or, although not shown, only a part is applied in the vicinity of the through hole 3.

As another example of processing the locking edge b, when a spring washer is used for the one member 1,
As shown in Fig. 11 (a), raw material continuously formed into a coil
In FIG. 11, when the center part of the through hole 3 is supported on the pedestal 12 and the outer peripheral edge of the tip part of the raw material 11 is blow-cut by the cutting member 13, as shown in FIG. 11 (b). Since the engaging edge b protruding inward from the end edge of the through hole 3 is formed to form the sandwiching hole 9, natural deformation at the time of manufacturing can be utilized.

When the spring washer is formed,
When a wire rod, which is a raw material, is wound around a winding rod to form a coil, the strain naturally formed in the inner hole (through hole) of the wire rod can be used as the above-described deformation process.

Further, although not shown in the figure, the protrusion process by the pressing force is performed by placing the one member 1 on the pedestal and performing a predetermined impact with an impact member such as a punch, as shown in FIG. 10 (e). As shown, the peripheral edge of the through hole 3 is formed with a locking edge b protruding to one side to form the sandwiching hole 9, and a curved bulging portion 14 is formed on the other side surface of the pressing force.

Furthermore, when the one member 1 is a plain washer,
When the washer 1 is punched out at the time of molding, it may be curved, and at that time, the through hole 3 may be formed in a plate-like shape, and an acute-angled locking edge b may be formed at one side edge thereof. Therefore, the washer can be manufactured and the locking edge b can be formed in the same process, which improves workability.

The engaging edge b of the through hole 3 formed by punching is normally formed in the through hole 3 which is perpendicular to the seat surface, but as another example, for example,
The shapes and the like shown in FIGS. 12 (a) to 12 (j) can be adopted, and any shape can be adopted as long as it can be engaged with the protrusion 4 of the other member 2.

In addition, the above-mentioned bending or bending or twisting,
Processing such as distortion is, for example, an arc shape as shown in FIG. 13 (a), an inverted C shape (the same as a normal C shape), or as shown in FIG. 13 (b). A step should be provided on the opposite side with a V-shape, or one should be inclined upward or downward as shown in Fig. 13 (c), or the periphery of the through hole 3 should be made as shown in Fig. 13 (d). It is something to make it liven up.

In forming the combined set A of the one member 1 and the other member 2 which have been subjected to this deformation processing, the through hole 3 of the one member 1 and the projection 4 of the other member 2 are aligned with each other. The through holes 3 and the protrusions 4 are engaged with each other by overlapping and pressing one or both of them, and they are integrally coupled by fitting and friction of both having a predetermined insertion resistance. .

When the coupling set A is fastened, as shown in FIG. 8, the female screw portion 5 of the other member 2 of the coupling set A is screwed onto the male screw portion 8 of the male screw body 7 to form a tool or the like. When tightened by the one member 1, the one member 1 is pinched between the mounting member 9 and the seat surface of the other member 2, and the deformation such as the curvature is gradually corrected to a smooth shape, and finally becomes flat to perform a washer action. .

At this time, the sandwiching hole 9 formed in the through hole 3 is
It is expanded by tightening, the engagement between the locking edge b and the outer periphery of the protrusion 4 is released, and the one member 1 and the other member 2 are free to rotate or move in the axial direction. The co-rotation does not occur.

Furthermore, if the deformed one member 1 is a spring washer, the clamping force spreads against the spring force due to the tightening in the above-mentioned action and becomes smooth. The movement is free, and when the other member 2 is loosened, the spring force of the other member returns to the original posture such as bending, and the other member 2 is engaged with the projection 4 to be integrated. It returns to the normal set state and can be repeatedly used for loosening.

In FIG. 14, reference numeral 15 is a meshing means, which is one member 1
By forming the protrusion 4 of the other member 2 into a cylindrical shape eccentric from the center of the through hole 3 with respect to the through hole 3 formed in The rotation of the male screw body 7 is not transmitted to the other member 2 due to the engagement of the through hole 3 and the protrusion body 4, and co-rotation of both is prevented. One member 1 is provided with a female screw. It is effective when

[0057]

As described above, according to the present invention, the one member having the through hole penetrating therethrough and the projection body fitted into the through hole so that the tip edge thereof does not protrude from the other surface of the through hole. By providing the other member projecting on one side, the one member and the other member can be integrally and temporarily fixed, and can be securely connected easily and quickly, and they can be separated during normal transportation and storage. Since it does not occur, the management of the screw set becomes good.

In the fastening work by fastening members of various industries, it can be easily used as a coupling set, and the workability and handling are good.

Further, since one member and the other member can be easily separated from each other by human hands, any kind of combination of the two members can be easily performed on site or the like. On the other hand, since it is not necessary to prepare a large number of members and materials for each operation, it is economical and storage and inventory management are space-saving and easy. It has special effects such as.
