[0003]

In this case, the insertion port has an inner diameter that is approximately the same as or slightly larger than the outer diameter of the connecting rod so that the connecting rod does not rattle. It was That is, the connecting rod can be held only straight along the axial direction of the insertion device. Therefore, in places with ups and downs and curves in the plane direction, the connecting rod itself should be bent along the ups and downs, or after cutting the connecting rod into short pieces, bend them like a pipe elbow. It has been necessary to take measures such as connecting with a ring or replacing the insertion port with a pole having a bend in a predetermined direction or having a universal joint structure. Therefore, the construction is troublesome and difficult, the appearance is not good, and the cost is further increased.

The present invention has been made in view of the above circumstances, and the construction can be easily performed even in a place having ups and downs and a curve in a plane direction, the appearance does not deteriorate, and the cost increases further. It is an object of the present invention to provide a pole for a fence structure that can suppress the above.

Since the cross-sectional shape is formed in a tapered shape, the connecting rod inserted inside the inner collar portion can be arbitrarily tilted within a predetermined range toward the entire circumference extending vertically or horizontally. Even if the inner brim portion inclines the insertion angle of the connecting rod in this way, it does not cause a peripheral gap that is inferior in appearance to the connecting rod.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a pole 1 according to the present invention. The pole 1 includes a core shaft 2, outer shell cylinders 3 and 4 fitted onto the core shaft 2, and a core shaft 2. And a cap member 5 which is capped on the top of the upper outer shell member 3. A socket member 7 is provided on the outer surface of the upper outer shell member 3 via a mounting base 6, and the socket member 7 holds the connecting rod 8. It is supposed to be done.

The mounting base 6 is, as shown in FIG. 2, a boss portion 1.
0, a mounting bolt 11 projecting from the boss portion 10,
It has a projecting piece 12 projecting from the boss portion 10 on the side opposite to the mounting bolt 11. The projecting piece 12 has a shape obtained by cutting the tubular body in half along the axial direction thereof, and has a notch-shaped screw through hole that vertically penetrates at the center portion in the width direction with the projecting end side as the open end. 13 is formed.
This mounting base 6 forms a bolt hole corresponding to the mounting bolt 11 at a predetermined height portion of the outer shell tube 3 (or the outer shell tube 4 or the crowned tube 5) at the standing position of the pole 1, and is also required. Accordingly, a counterbore (not shown) for the boss portion 10 is provided on the peripheral portion of the bolt hole, and then the whole is screwed and attached. In the mounting posture, the curved concave surface of the projecting piece 12 is adjusted to face upward so that the connecting rod 8 can be supported on the upper part of the projecting piece 12. Although the bolt holes for the outer shell cylinder 3 and the like may be formed from the beginning, the outer shell cylinder 3
In order to expand versatility such as, it is preferable to perform on-site processing.

The socket member 7 is formed in a laterally short cylindrical shape into which the projecting piece 12 can be fitted, and a screw 15 is screwed on the outer peripheral portion thereof in correspondence with the screw hole 13 of the projecting piece 12. Mating screw holes are provided. Further, an inner flange portion 16 projecting from the entire circumference to the inner circumference direction is formed at an end edge portion of the socket member 7 opposite to the mounting base body 6. The inner flange portion 16 has a cross-sectional shape that tapers toward the protruding end thereof, and the insertion angle of the connecting rod 8 can be arbitrarily tilted within a predetermined range toward the entire circumference extending vertically or horizontally. Therefore, even if the up and down ups and downs or the curve in the plane direction are present on the standing ground of the pole 1, the connecting rod 8 is erected in a predetermined direction without exchanging parts, changing the position, or processing the socket member 7. Can be held.

Initially, the socket member 7 is inserted into both ends of the connecting rod 8 with the inner flange portions 16 facing inward, and the both ends of the connecting rod 8 are supported on the respective projecting pieces 12. Then, the socket members 7 on both sides are attached to the corresponding protruding pieces 1
Make sure to slide it so that it fits onto 2. Then screw 15
Is tightened until the connecting rod 8 becomes immobile. When the connecting rod 8 is tilted, the end of the connecting rod 8 abuts the boss portion 10 of the mounting base 6 or the inner surface of the socket member 7 due to the relationship between the length of the connecting rod 8 and the distance between the poles 1. When interfering, it is sufficient to scrape off the obstacle on the side of the connecting rod 8.

By the way, the outer shell cylinders 3 and 4 and the crowned cylinder 5 are
It is formed into a cylindrical shape by casting of iron, bronze, aluminum or the like, and the core shaft 2 is formed of a hollow pipe material made of steel. In each case, the individual weight is kept within a range that can be handled by hand without any difficulty. In order to erect this pole 1, first, in FIG. 1, a hole of a predetermined depth is dug in the foundation surface GL, and the split stone layer 20,
The discarded concrete layer 21 and the foundation concrete layer 22 are formed in this order. A shaft hole 23 for the core shaft 2 is formed in the basic concrete layer 22. After the foundation concrete layer 22 is hardened, the core shaft 2 is vertically inserted into the shaft hole 23, and the adhesive mortar 24 is filled and fixed. After that, the outer shell cylinders 4 and 3 are fitted onto the core shaft 2, and a predetermined amount of adhesive mortar 25 is put into the crown mounting cylinder 5 to cover the core shaft 2.

In the present invention, the protruding piece 12 is the outer shell tube 3.
It may be integrally formed at the same time as casting, or may be fixed by welding or the like after casting. The shape of the protruding piece 12 is not limited in any way, and may be a flat plate or a rod. Of course, this protruding piece 1
The screw through hole 13 provided in 2 may be a long hole or a circular hole. By fixing the socket member 7 to the outer shell cylinder 3 from the beginning, the protruding piece 12 can be omitted.

The connecting rod 8 may be a square pipe or a solid material having various sectional shapes. In the socket member 7, in the above-described embodiment, the cross-sectional shape of the inner flange portion 16 is inclined toward the back of the socket member 7, but the present invention is not limited to this.
Starting with those that are inclined outward as in (a),
It is also possible to incline both inward and outward as in the trapezoidal shape of (b), the semicircular shape of (c), and the triangular shape of (d). It is also possible that the protruding portion of the inner flange portion 16 is separately formed of rubber, resin or the like, and is fixedly adhered in a predetermined manner.

As shown in FIG. 4, a screw 1 is attached to the socket member 7.
In the state where 5 is screwed, a pressing tool 26 that bends along the connecting rod 8 may be rotatably attached to the threaded end thereof. The structure of the pole 1 itself is not limited to the core shaft 2, the outer shell cylinders 3, 4, and the crown sleeve 5, but may be a solid or hollow integral body. Further, when it can be predicted that the inclination of the connecting rod 8 is substantially constant, the end face of the connecting rod 8 is cut at a predetermined angle to form the contact surface 30 as shown in FIG.
0 may be brought into contact with the boss portion 10 of the mounting base 6. In this case, the amount of adjustment of the insertion angle of the connecting rod 8 is small, but since the contact area of the connecting rod 8 against the boss portion 10 can be made large, there is an advantage that the rattling of the connecting rod 8 can be prevented.

Further, as shown in FIG. 6, a curved chamfered portion 31 may be formed on the end surface of the connecting rod 8. In this case, since the connecting rod 8 comes into line contact with the inner surface of the boss portion 10 and the socket member 7, it is superior to the case of FIG. 5 in that the inclination angle of the connecting rod 8 can be changed, and the rattling of the connecting rod 8 There is an advantage that can be made smaller than in the case of FIG.

[0017]

The present invention has the above-mentioned structure, and since the socket member is provided with the inner collar portion having a tapered cross section, the connecting rod inserted into the inner collar portion is vertically or horizontally. It can be tilted arbitrarily within a predetermined range toward the entire circumference. That is, since it is not necessary to bend the connecting rod or use a bending coupling, and it is not necessary to use a spigot equipped with a bending structure or a universal joint structure, it is possible to perform up-and-down ups and downs and a curve in a plane direction. The fence can be easily installed even in a certain place. Moreover, it does not look bad and the cost does not soar.

Parts such as the socket member and the protruding piece can be shared, and the manufacturing cost can be reduced.
