Claims

[Scope of Claim for Utility Model Registration] 1. A pin consisting of a small diameter part and a large diameter part, and a continuous part of the small diameter part and the large diameter part is tapered, and the pin is connected to the opening in the side surface of the horizontal pipe to the small diameter part. The end of the lattice pipe, which was also inserted into the opening, is press-fitted onto this pin and expanded along the tapered part to be larger than the diameter of the opening. in which the lattice pipe is inserted until the tip end surface is pressed against the inner wall surface of the horizontal beam pipe, and a second small diameter portion is formed at the end of the large diameter portion of the pin opposite to the small diameter portion, Between the outer circumferential surface of the second small diameter part and the inner circumferential surface of the lattice pipe
A pipe fence characterized by a gap. 2. The pipe fence according to claim 1, wherein the end surface of the lattice pipe that is pressed against the inner peripheral surface of the horizontal pipe is cut off into an arc shape with a radius that matches the inner wall surface of the horizontal pipe having a circular cross section. 3. A pin consisting of a small diameter part and a large diameter part, in which the continuous part of the small diameter part and the large diameter part is tapered, is inserted into the opening on the side of the horizontal pipe with the small diameter part facing outside. The end of the lattice pipe, which was also inserted into the opening, is press-fitted onto this pin and expanded along the tapered part to be larger than the diameter of the opening. A pipe fence characterized in that the end surface of the pin, which is pressed against the inner wall surface of the horizontal pipe, on the opposite side from the small diameter portion is shaped like a sphere or an arc having a radius that matches the radius of the inner wall surface of the horizontal pipe. . 4. A pin consisting of a small diameter part and a large diameter part, in which the continuous part of the small diameter part and the large diameter part is tapered, is inserted into the opening in the side of the horizontal pipe with the small diameter part facing outside. The end of the lattice pipe, which was also inserted into the opening, is press-fitted onto this pin and expanded along the tapered part to be larger than the diameter of the opening. A pipe fence characterized in that a groove is formed in one or both of the end face opposite to the small diameter portion and the end face of the lattice pipe, and the groove is engaged with a protrusion on an inner wall surface of the horizontal pipe. 5. A pin consisting of a small diameter part and a large diameter part, in which the continuous part of the small diameter part and the large diameter part is tapered, is inserted into the opening on the side of the horizontal pipe with the small diameter part facing outside. and the end of the lattice pipe, which was also inserted into the opening, is press-fitted onto this pin and expanded along the tapered part to be larger than the diameter of the opening; A cylindrical body having a flange-like part that covers the outer peripheral edge of the horizontal pipe is inserted between the opening and the lattice pipe,
A pipe fence characterized in that the lattice pipe is held expanded along the tapered expanded portion.
