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. The other end of the outer cylinder 1 is provided with a large-diameter portion 1h (for example, 0.2 to 0.4 mm thicker) that is thicker than the outer diameter of most of the outer cylinder 1. In addition, 2 facing each other on the diameter near the pointed portion 1d
Holes 1c are provided at some places. The hole 1c of the outer cylinder is a long hole that is long in the axial direction of the outer cylinder. 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.

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. At the boundary between the shaft main body 2a and the head 2b, there is a 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.

Further, on the outer circumference of the shaft, a plurality of circumferential projections 2e for sealing are formed by rolling. A rotating circular die is pressed against the rotating shaft, and the circumferential ridges 2e are raised by plastic deformation (height: about 0.1 to 0.2 mm). Approximate size makes it easy to fit the outer cylinder 1, has a waterproof effect, and does not hinder the driving of the shaft 2.

The ring-shaped anchor member 4 is interposed between the lower end of the shaft 2 and the guide member 5 above the pointed portion 1c, and the lower end faces the hole 1c of the outer cylinder 1. The anchor member 4 is formed by cutting a round steel pipe into an oval shape and inserting the anchor member 4 with its major axis direction aligned with the axial direction of the outer cylinder, and the lower part thereof faces the hole 1c.

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 10 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.
A case of fixing the above with the fixture of the present invention will be described. When the head 2b of the shaft 2 is hammered and driven in with a hammer, the outer cylinder 1 and the shaft 2 have the spacer cylinder 6, so that they are integrated and the flange 1b of the outer cylinder 1 is driven in and stopped.

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 protrudes in a loop form from the hole 1c of the outer cylinder in the axial direction, and enters the inside of the base material B. Therefore, it becomes a strong retaining anchor.

Since the outer cylinder 1 has a large-diameter portion 1h at the lower end thereof, most of the outer cylinder 1 does not come into contact with the driven layer when the outer cylinder 1 is driven, so that the driving resistance is greatly reduced. However, the impact force of the operator is small (there is no risk of buckling << buckling >> phenomenon).

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 provides an anchor against the pulling force of the nail. 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 2 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.

FIG. 5 shows another embodiment. The guide member 5
The lower end of the outer cylinder is a pointed portion, and is replaced with the outer tube tipped portion 1d. That is, in the guide member 51, a downwardly pointed peak portion 51b is integrally formed at the lower end of a cylindrical portion 51a that is concentric with the cylindrical main body 1a of the outer cylinder 1, and the outer diameter of most of the outer cylinder is on the outer cylinder side. A large-diameter portion 1h thicker than the above is provided, and the upper end is a flat surface. Then, the circumferential groove 5 is formed on the outer circumference of the cylindrical portion 51a.
1c is provided, and a bent piece 1g at the lower end of the outer cylinder 1 is provided on the 1c.
It is fitted by caulking.

Further, as shown in FIG. 6, the lower half portion of the outer cylinder 1 is formed so as to have a plurality of concave-convex strips along the axial direction, and the fixing force is increased. In this case, if the anchor member 4 is interposed between the opposing ridges and the holes 1c are provided in these portions, the anchor member 4 can be easily and reliably positioned with respect to the hole 1c. Further, in this case, the outer diameter of the shaft 2 is slightly increased,
When a "tightening margin" is generated, the adhesive 3
Can be omitted. Also, as shown in FIG. 7, even in the case where the axial cross section of the lower half of the outer cylinder 1 is rectangular (square), the adhesive 3 can be omitted by increasing the thickness of the shaft 2 to make a tight margin.

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. The anchor member 4 may be fixed to the shaft 2 with an adhesive, welding, or the like.

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

As shown in FIG. 11, when the spacer cylinder 6 is not provided, when the shaft 2 is hit, the outer cylinder flange 1b reaches the object to be fixed, or until just before the anchor member, the anchor member. The anchor member is pressed against the inner wall of the outer cylinder 1 by its elastic restoring force so that the frictional force of 4 does not come out of the hole of the outer cylinder 1c. Here, 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. In the case of an anchor member 4 in which a round steel pipe with a thickness of 1.1 mm is sliced into a circle with a width of 1.1 mm and deformed into an oval, the inner diameter of the outer cylinder 1-the outer diameter is 2.5 mm-3.5 mm,
2.8 mm-3.8 mm, 3.0 mm-4.0 mm, the outer flange 1b has a diameter of 8 mm or more, and a 1.2 mm thick round steel pipe was sliced into 1.2 mm width and transformed into an oval shape. In the case of the anchor member 4, the inner diameter of the outer cylinder 1-the outer diameter is 3.2 mm-4.2 mm,
4.5mm-5.5mm, the diameter of the outer cylinder flange 1b is 10mm or more.

When the spacer 6 is not provided and the frictional force of the anchor member 4 to the outer cylinder 1 is not sufficient, the adhesive force of the adhesive 3 is increased. As a result, until the outer cylinder 1 is driven up to the flange 1b, the outer cylinder 1 is driven integrally with the shaft 2, after which the adhesive 3 is released from the fixation, and the shaft 2 is driven into the outer cylinder 1.

Further, as shown in FIG. 8, instead of the adhesive 3, a plurality of convex portions 3a are provided on the outer periphery of the columnar main body 2a at equal intervals in the circumferential direction, and these are "tightened" with the inner surface of the outer cylinder 1. It becomes a "siege margin", and both are integrated until the outer cylinder 1 is driven in. Instead of the convex portion 3a, the axial ridge 3
b is arranged in the circumferential direction, or a circumferential ridge is provided. Further, these convex portions 3c or ridges are pressed (or hit) from the outside of the outer cylinder 1 (or the rotating circular die is pressed against the outer cylinder that rotates in the same manner as described above), so that You may make it extrusion-molded.

Alternatively, as shown in FIG. 9, 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.

FIG. 10 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. Also, the lower part of the shaft 2 and the anchor member 4
Apply the sealant over the top of the. Other, outer cylinder 1
As a waterproofing means for the inside, a rotary round die is pressed from the outside of the rotating outer cylinder 1 to form a circumferential ridge for sealing on the inner circumference of the outer cylinder. Alternatively, as shown in FIG. 9, the ring packing 9 is interposed.

As shown in FIG. 12, the anchor member 4 is made of steel and is bent into an inverted U shape, and both ends 4a of the wire are on the lower side. It is bent so as to face the inside of the hole 1c. In this embodiment, as shown in FIG. 13, when the shaft head 2b is driven through the washer 10 to the surface of the flange 1b of the outer cylinder 1, the anchor member 4 sequentially comes out from the hole 1c of the outer cylinder in the axial direction. , Penetrates into the base material B and becomes an anchor. Here, while the lower lower surface of the anchor member 4 receives a reaction force by the upper surface of the guide member 5,
The guide member 5 is strongly pressed against the corner portion 5a of the upper peripheral edge, and the tip of the anchor member 4 bends upward. 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 while being strongly sandwiched between the upper and lower surfaces in the portion passing through the outer cylinder hole 1c.
It is "squeezed" and bends in an upward arc.

FIG. 14 shows another embodiment using an inverted U-shaped anchor member. 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. 15 shows still another embodiment using an inverted U-shaped anchor member, in which the spacer cylinder 6 is not provided. The upper surface of the guide member 51 becomes a pointed peak portion 51e facing upward, and the anchor member 4 easily comes out of the hole 1c. When the shaft 2 is struck, until the outer cylinder flange 1b reaches an object to be fixed, or just before the outer cylinder flange 1b reaches the fixed object, the anchor member 4 generates a frictional force that does not come out from the outer cylinder 1c hole. The anchor member is in pressure contact with the inner wall of the outer cylinder 1 by its elastic restoring force. Here, 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 4 is 1.1 mm, the inner diameter of the outer cylinder 1-outer diameter is 2.5 mm-3.5 mm,
2.8 mm-3.8 mm, 3.0 mm-4.0 mm, outer cylinder flange 1b has a diameter of 8 mm or more. When the diameter of a round wire of anchor 4 is 1.2 mm, the inner diameter of outer cylinder 1-the outer diameter is 3 mm. .2mm-4.2mm,
4.5mm-5.5mm, the diameter of the outer cylinder flange 1b is 10mm or more.

In FIG. 20, the large diameter portions 1h and 51d shown in FIGS. 1, 5, 14, and 15 are provided with knurled portions 51f consisting of a large number of projections along the axial direction. In this case, the resistance is further reduced and it is easy to drive. Also,
FIG. 21 shows an example in which the large diameter portion is formed into a polygonal shape close to a cylinder.

The anchor member 4 is replaced with the anchor member shown in FIGS.
As shown in FIG. 7, both ends of a l-shaped (cursive lowercase letter) wire rod is bent outward, or FIG.
As shown in FIG. 8 and FIG. 19, a strip-shaped thin plate piece is cut along the length direction from the lower side to the front side and bent into a human-character (or letter-shaped) shape. Alternatively, a J-shaped wire (not shown) may be used, and this wire may come out from one hole of the outer cylinder. The anchor member 4 may be formed integrally with the shaft 2 or may be separately secured by an adhesive, welding or the like.

The present invention can be applied to a wide range of applications as a fixture for other members such as nails, drawing scales, folding scales and the like.
In addition to the above, as the material of the base that is the member to be driven, it is applied to wood wool cement plate, wood, folding, metal plate 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.

[0037]

According to the structure of the present invention, since the anchor member projects in the length direction from the side surface near the tip of the outer cylinder, the anchor member smoothly enters without breaking the layer. 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.

Since there is a large diameter portion on the other end of the outer cylinder or on the outer cylinder side of the pointed portion, when driving the outer cylinder, the hammering resistance is greatly reduced, and the impact force of the operator is small. I'm sorry.
