[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below based on an embodiment shown in the drawings. 1, 2, and 3, the outer cylinder 1
Has a concentric round flange 1b on the upper end of a steel cylindrical body 1a, and the lower end is bent to form a pointed portion 1d. Also,
Holes 1c are provided at two diametrically opposed positions near the pointed portion 1d. The hole 1c of the outer cylinder is a long hole that is long in the axial direction of the outer cylinder. The outer cylinder 1 is formed by bending a rectangular flat plate into a cylindrical shape.

The outer cylinder flange 1b is a donut-shaped plate which is separate from the cylinder main body 1a, the hole periphery of the donut-shaped plate is bent downward, and the upper end of the cylinder main body is expanded and bent so that the cylinder main body is bent. In a state where the donut-shaped plate is fitted in, the bent portion of the donut-shaped plate is squeezed and fixed to the tube body.

The cylindrical main body 2a of the steel shaft 2 is inserted from the upper end of the outer cylinder 1 and has a concentric round head 2b at the upper end, and at the boundary between the shaft main body 2a and the head 2b, it is located on the head side. A widening taper surface 2c is formed. A positioning recess 2d is formed on the lower end surface of the shaft 2. Then, an adhesive (or pressure-sensitive adhesive) 3 is applied to the outer periphery of the columnar body 2a, and the shaft 2 is prevented from coming off by adhesion or friction with the inner surface of the cylindrical body 1a of the outer cylinder 1.

The rod-shaped anchor member 4 is interposed between the lower end of the shaft 2 and above the pointed portion 1c, and the lower end faces the hole 1c of the outer cylinder 1. The anchor member 4 is made of a round wire made of steel, which is bent in an inverted U shape, and both ends 4a of the wire are on the lower side. The both ends 4a are bent so as to face the hole 1c of the outer cylinder 1. ing.

The spacer cylinder 6 includes an outer cylinder flange 1b and a shaft head 2.
It is interposed between b and. The spacer cylinder 6 is made of a plastic (synthetic resin) cylinder, and is thinner (thin-walled portion 6a) than the other portion (thick-walled portion 6a) on one side with the axial direction as a boundary.
Have been. An inclined surface 6c is provided at the shaft head side end surface of the one side portion (thin portion 6b) so that the upper surface of the thin portion 6b is lowered.

A washer 9 is interposed at the boundary between the spacer 6 and the cylinder body 1a.

In the above, in FIG. 4, the exterior material A such as roof tile or wood board is attached to the surface of the lightweight cellular concrete base material B.
The case of fixing with the nail of the present invention will be described. Axis 2 with a hammer
When the head 2b of the head is hit and driven, the outer cylinder 1 and the shaft 2 are
Has a spacer tube 6, so they are integrated,
The outer cylinder 1 is driven up to the flange 1b and stops.

When subsequently hit, the outer cylinder 1 is flanged 1b.
Since the movement of the spacer 2 is stopped by the head 2b of the shaft 2, it is compressed by the head 2b of the shaft 2, and the inclined surface 6c of the spacer cylinder 6 and the tapered surface 2c of the shaft 2 cause the radius toward the thick portion 6a side with the axis as a boundary. A directional component force is generated at the upper part of the spacer cylinder 6. For this reason, the spacer cylinder 6 inclines from the upper portion in the radial direction from the upper portion, as shown in phantom, and the thin portion 6b is strongly pressed by the shaft 2 and is broken from the shaft 2. When the shaft is driven, the spacer cylinder is gently separated in almost one direction without vigorously scattering around. At this time, the washer 9
Prevents the lower part of the spacer cylinder 6 from being caught between the shaft and the outer cylinder.

By the subsequent impact, the adhesion of the adhesive 3 is released, and the shaft head 2b is driven through the washer 9 to the surface of the flange 1b of the outer cylinder 1. At this time, the anchor member 4 sequentially comes out from the hole 1c of the outer cylinder in the axial direction and enters the inside of the base material B.

Here, the positioning recess 2 is formed on the lower end surface of the shaft 2.
Since there is d, the shaft 2 and the anchor member 4 are held so that their axes are substantially aligned with each other, and the anchor member 4 smoothly exits from the outer cylinder. Further, since the hole 1c is a long hole, strict accuracy is not required for positioning the tip of the anchor member 4 with respect to the hole. Moreover, the direction is guided in the length direction of the hole 1c,
There is a case where the anchor member 4 goes out of the outer cylinder, and in this case, the anchor member 4 has a balanced posture in the portion that comes out of the outer cylinder. This creates an anchor that resists the pulling force. Further, since the spacer cylinder 6 is provided, the shaft 2 does not advance in the outer cylinder until the outer cylinder 1 is completely driven. Therefore, the anchor member 4 projects from the outer cylinder only after the outer cylinder 1 is hit, and the periphery of the driving layer is not undesirably destroyed.

Here, when the shaft 3 comes out of the outer cylinder 1 during handling of the adhesive 3 or when a force in the opposite direction acts on the shaft 2 due to the elastic restoring force of the anchor member 4 during driving of the shaft 2, Resist this.

Next, an embodiment of a method for manufacturing the present member fixing tool will be described with reference to the drawings. In FIG. 17, the strip is sent to the right, and in the first step, a hole corresponding to the outer cylinder hole 1c is punched near the front end of the strip with a press punch. In the second step,
The strip is pressed into a rectangular flat plate. In the third step, a plurality of (two in the drawing) triangular mountains are cut off so that one triangular side of the rectangular flat plate is continuous. In the fourth step, the flat plate having the triangular mountain portion is formed into a cylindrical body (corresponding to the outer cylinder 1) having a central axis along the long side. In the fifth step, the triangular mountain portion of the cylindrical body is formed into a cone shape (corresponding to the apex portion 1d). In a sixth step, the end portion of the cylindrical body on the side opposite to the triangular mountain portion is expanded and bent. In the seventh step, a donut-shaped plate to be the flange 1b is inserted (press-fitted) from the conical end of the cylindrical body. This prevents springback (elastic recovery) of the cylinder. In the eighth step, the guide member 5 is inserted from the enlarged diameter end portion of the cylindrical body. In the ninth step, the rod-shaped anchor member 4 is inserted from the enlarged diameter end of the cylindrical body. In the tenth step, the shaft 2 having the convex portion 3 is inserted from the expanded end portion of the cylindrical body.

Now, in the third step, the heights of the two triangular peaks differ by h. As a result, when the triangular mountain portion is formed into a conical shape in the fifth step, as shown in the eighth step diagram of FIG. 17, the lower mountain enters the inside of the higher mountain and the higher mountain has a sharp pointed shape. Present.

Incidentally, during the cylindrical bending work of the fourth step, as shown in FIG.
It is performed by a well-known mold such as 8. That is, U-bending is performed by the lower die M1 and the upper punch M2, and then curling is performed by the upper and lower dies M3 and M4 having semi-cylindrical die surfaces to form a cylindrical body.

In the conical machining in the fifth step, as shown in FIG. 19, a cylindrical guide M6 is provided so as to surround the upward punch M5, and an outer cylinder (shown in phantom) is inserted between them. . Then, an upper mold M7 having a conical hole is provided. Then, the upper mold M7 is lowered to mold (contract and bend) the conical portion of the outer cylinder.

In the sixth step of expanding the diameter, as shown in FIG. 20, the lower mold M8 is inserted into the hole of the lower mold M8 with the conical portion 1d of the outer cylinder facing down, and the upper mold is positioned with the lower mold M9. To do. Then, the upper die punch M10 having the downward conical surface descends,
Expanded.

The order of the first step, the second step, and the third step can be changed by any combination thereof.

FIG. 9a shows another embodiment of the outer cylinder flange. The outer cylinder flange 1b is a doughnut-shaped plate that is a separate body from the cylinder body 1a, and the upper end of the cylinder body 1a is expanded and bent. The sleeve 11 is closely inserted from the other end of the outer cylinder in a state where the donut-shaped plate is fitted to the cylinder body,
These parts do not fall out. Sleeve 1
Reference numeral 1 is a molded product of synthetic resin, and an outer flange 11b is provided at one end of a cylindrical body 11a, and a tapered taper surface 11c is provided at the other end. Further, when a disc spring or a disc spring is used as the donut-shaped plate, it damps vibrations and impacts and prevents the driven body from loosening.

FIG. 5 shows another embodiment. The hole 1c of the outer cylinder is cut out on the upper side and bent inward to form a guide piece 1e, on which the lower end of the anchor member 4 is supported.

FIG. 6 shows another embodiment. A cylindrical guide member 5 is provided inside the lower portion of the outer cylinder 1 and between the pointed portion 1d and the hole 1c. The upper end of the guide member 5 is a flat surface that is substantially perpendicular to the axial direction of the outer cylinder 1. In this case, as shown in FIG. 6, the lower lower surface of the anchor member 4 receives a reaction force by the upper surface of the guide member 5 and is strongly pressed against the corner portion 5a of the peripheral edge of the upper surface of the guide member 5, so that the tip end of the anchor member 4 is pushed. Bends upwards. By the subsequent hammer impact, the upper surface of the portion where the anchor member 4 passes through the outer cylindrical hole 1c is also strongly pressed against the corner angle 1f of the outer cylindrical hole 1c. As a result, the anchor member comes out of the outer cylinder in a state where it is strongly sandwiched between the upper and lower surfaces in the portion passing through the outer cylinder hole 1c, so that the anchor member is "squeezed" and bends in an upward arc shape. I will do it.

FIG. 7 shows still another embodiment. The lower end of the guide member 5 is a cusp and is replaced with the outer cylinder cusp 1d. That is, the guide member 51 is the cylindrical body 1 of the outer cylinder 1.
At the lower end of the cylindrical portion 51a that is concentric with a
b is integrally formed, and the upper end is a flat surface. A circular groove 51c is provided on the outer circumference of the columnar portion 51a, and the bent piece 1g at the lower end of the outer cylinder 1 is fitted into the circular groove 51c by caulking.

Further, as shown in FIG. 8, the outer cylinder 1 is formed so as to have a plurality of concavo-convex stripes along the axial direction, and the fixing force increases. In this case, if the anchor member 4 is interposed between the ridges facing each other and the holes 1c are provided in these portions, the anchor member 4
The positioning with respect to the hole 1c becomes easy and reliable. Also,
In this case, the adhesive 3 can be omitted if the outer diameter of the shaft 2 is made slightly thicker to cause a "tightening margin". Further, even when the outer cylinder 1 has a rectangular (square) cross-section as shown in FIG. 9, the adhesive 3 can be omitted by increasing the thickness of the shaft 2 to make a tight margin.

The anchor member 4 is replaced by the anchor member shown in FIGS.
As shown in FIG. 1, a l-shaped (lowercase alphabetic character) letter wire is bent outward at both ends, or
As shown in Nos. 2 and 13, a strip thin plate piece is cut along the length direction from the lower side to the front side and bent into a human-character shape (or a letter-shape). Alternatively, a J-shaped wire (not shown) may be used so that it exits from one hole of the outer cylinder. The anchor member 4 is formed integrally with the shaft 2 or is separately secured by an adhesive, welding, or the like.

As the anchor member, a usual material for nails is used. Also, if you use spring material such as stainless spring steel,
Since it is rich in elasticity, even if the positional relationship between the outer cylinder 1 and the anchor member is displaced due to an earthquake or the like, the original state is restored and the fixing strength is strong.

If, instead of or in addition to the above, a plurality of grooves 6d (imaginary lines in FIG. 1) along the axial direction are provided on the outer periphery of the spacer cylinder 6, this portion will also be destroyed.

When the spacer cylinder 6 is not provided, the adhesive force of the adhesive 3 is increased. As a result, until the outer cylinder 1 is driven in, the outer cylinder 1 is driven integrally with the shaft 2, after which the adhesive 3 is unfixed and the shaft 2 is driven into the outer cylinder 1. Further, as shown in FIG. 14, instead of the adhesive 3, a plurality of convex portions 3 are provided on the outer periphery of the columnar main body 2a at equal intervals in the circumferential direction, and this is a "tightening margin (screw) with the inner surface of the outer cylinder 1. "), And both are integrated until the outer cylinder 1 is driven in. Instead of the convex portion 3, axial ridges are arranged in the circumferential direction, or circumferential ridges are provided. Further, these protrusions or ridges may be pressed (or hit) from the outer side of the outer cylinder 1 to be projected and formed on the inner side of the outer cylinder 1. Alternatively, as shown in FIG. 15, a circumferential groove 2c may be provided on the outer circumference of the shaft 2 and the ring packing 9 may be fitted therein. These modifications are applied even if the spacer cylinder 6 is provided, but the adhesive force between the outer cylinder and the shaft is set to a small value so that the shaft does not come out.

Further, when the spacer 6 is not provided,
The anchor member 4 has a wire bent in an inverted U shape,
When is hit, until the outer cylinder flange 1b reaches the object to be fixed, or just before reaching, the anchor member 4 generates a frictional force that does not come out of the outer cylinder hole 1c,
The anchor member 4 presses and contacts the inner wall of the outer cylinder 1 by its elastic restoring force. Then, as an experimental example (example), an example of dimensions when a wood plate is fixed to the surface of the lightweight cellular concrete base material B and a particle board is fixed is shown. When the diameter of the round wire of the anchor member 4 is 1.1 mm, the outer diameter of the outer cylinder 1-the outer diameter is 2.5-3.5 mm, 2.8-3.8 m.
m, 3.0-4.0 mm The diameter of the outer cylinder flange 1b is 8 mm or more. When the diameter of the round wire of the anchor member 4 is 1.2 mm, the inner diameter of the outer cylinder 1-outer diameter is 3.2-4.2 mm, 4.5-5.5 m.
m, the diameter of the outer cylinder flange 1b is 10 mm or more.

FIG. 16 shows another embodiment of the shaft. The shaft has no head, and the sealing material layer 8 is applied to the upper part of the shaft. In this case, after driving the shaft 2 into the outer cylinder 1, the sealing material layer 8
Prevent rainwater from entering.

In order to manufacture the embodiment of the fixture shown in FIG. 7, the third step (triangular mountain formation) and the fifth step (pyramidal formation) shown in FIG. 17 are deleted. And the 8th, 9th,
Instead of the 10 steps, the anchor member 4 and the guide member 51 are inserted from the end opposite to the expanded end of the cylindrical body, and the guide member 51 is inserted.
Is caulked or fixed by welding, and then the shaft 2 is inserted from the expanded diameter end of the cylindrical body.

When manufacturing the fixture shown in FIGS. 1, 2, 5 and 6, the height difference h in the third step shown in FIG. 17 is naturally zero. Further, when the cylindrical body is formed from the plate in the above, welding may be applied to the joint.

When the outer cylinder 1 is not made of a plate but a ready-made round pipe, a flange portion is formed as in the sixth step of FIG. 17, and a donut-shaped plate is inserted as in the seventh step. (Or, the donut-shaped plate is not inserted and only the forming flange portion is formed.) Then, as shown in FIG. 7, the anchor member 4 and the guide member 51 are inserted and the guide member 51 is fixed.

The present invention can be applied to an extremely wide range of applications such as nails, drawing hooks, tatami hooks, and other member fixing tools.
In addition to the above, the material of the driven member is applied to wood wool cement board, wood, tatami mat and the like.

The present invention is not limited to the examples and embodiments described above, but includes various modifications without departing from the spirit and scope of the claims.

[0044]

According to the structure of the present invention, since the rod-shaped anchor member projects in the length direction from the tip of the rod from the side surface near the tip of the outer cylinder, the anchor member smoothly enters without breaking the layer. To do. Therefore, the stability of the base of the fixture is also good. In addition, since the tip of the fixing tool can be formed into a pointed shape, it is easy to drive and the layer is not broken undesirably. Moreover, since the thickness is determined by the outer cylinder and the shaft or the outer cylinder and the anchor member, the thickness can be made thinner than the conventional one, and it is easy to drive and the waterproof around the driven nail is also easy. Moreover, the pull-out proof strength can be freely designed by selecting the thickness, material strength and length of the anchor member.

Also, because of the spacer cylinder, the shaft does not advance in the outer cylinder until the outer cylinder is driven almost completely. Therefore,
It is possible to prevent the anchor member from protruding from the outer cylinder almost completely after the outer cylinder has been driven in, and inconveniently destroying the periphery of the driving layer.

The outer cylinder flange is a donut-shaped plate separate from the cylinder body, and the hole periphery of the donut-shaped plate is bent downward,
One end of the tube body is expanded and bent, and in a state where the donut-shaped plate is fitted to the tube body, the bent portion of the donut-shaped plate is squeezed and fixed to the tube body. Therefore, the flange is attached to the outer cylinder by a die and a press, which is suitable for mass production.

The outer cylinder flange is a donut-shaped plate separate from the cylinder main body, one end of the cylinder main body is expanded and bent, and the sleeve of the outer cylinder is fitted with the donut-shaped plate fitted to the cylinder main body. Inserted from the other end, these parts form a set. Therefore, press equipment for attaching the flange to the cylinder body is not required. Also, when driving through a waterproof sheet,
Waterproof effect increases at the sleeve.

When the outer cylinder flange is a disc spring or a disc spring,
Has a retaining effect by buffering.

The outer cylinder is manufactured at low cost because the plate is bent and bent into a cylinder.
