BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a gate for restricting traffic according to the present invention. The traffic-restricting gate 1 of the present invention exemplified in FIGS. 1 to 3 is constituted by a pair of curved fences 2 and 8 formed by a pair of substantially semicircular arcs.

One of the curved fences 2 is a single vertical rod for connecting the lower horizontal rod 3 and the upper horizontal rod 4 with the lower horizontal rod 3 and the upper horizontal rod 4 formed of a pipe having a thickness of about 60 mm. It comprises rods 5, 6 and a vertical rod 7 formed by bending a rod into an inverted U-shape. Each of the upper and lower horizontal rods 3 and 4 has the same radius and is formed in a substantially semicircular shape with a radius of 900 mm, and its center is shifted by about 200 mm and one end is formed by a single vertical rod 6. The other end is connected to each other by the inverted U-shaped vertical rod 7, and the center is connected to a single vertical rod 5 so that the height difference between them is 250 mm.

The other curved fence body 8 has substantially the same structure as the curved fence body 2, that is, a substantially horizontal semi-circular lower horizontal rod 9 having a radius of 900 mm and an upper part formed of a pipe having a thickness of about 60 mm. The horizontal rod 10, the lower horizontal rod 9 and the upper horizontal rod 10
And a single vertical rod 11 whose center is shifted by about 200 mm,
12 and a vertical rod 13 formed by bending a rod into an inverted U-shape
The height difference between the upper and lower horizontal bars 9 and 10 is also 250 mm.

The inverted U-shaped vertical rod 7 constituting the curved fence body 2 and the inverted U-shaped vertical rod 13 constituting the curved fence body 8 are particularly apparent in FIG. As described above, the inside of the inverted U shape is used as a display plate.

The curved fences 2 and 8 are erected on the ground by respective vertical rods. The inside of each semicircular arc is opposed to each other, and the upper horizontal rod 4 of the curved fence 2 is formed. The vertical rod 12 of the curved fence 8 is positioned at the center C1 of the circle, and the center of the semicircle is shifted in the horizontal direction and is erected.
Therefore, the curved fence body 8 is located at the center C2 of the circle of the upper horizontal rod 10.
The vertical bar 6 of the curved fence body 2 is disposed at a position, and the curved fence bodies 2 and 8 form a traffic-restricting gate 1 having a substantially S-shaped passage in plan view. .

The height of the traffic restriction gate 1 is 640 mm from the ground to the upper horizontal rods 4 and 10, respectively.
Therefore, the lower horizontal rods 3 and 9 provided at a lower part of 250 mm from these have a height of 390 mm from the ground,
The distance between the semicircular center C1 of the curved fence 2 and the upper horizontal rod 4 of the curved fence 2 in FIG.
mm, and the distance on the plane from the center C1 to the vertical rod 5 of the lower horizontal rod 3 is 900 mm + 200 mm = 1.
It is as wide as 100 mm.

Similarly, the distance between the semicircular center C2 of the curved fence body 8 and the upper horizontal rod 10 of the curved fence body 8 on the plane is a narrow width of 900 mm, and the distance between the center C2 and the lower horizontal rod 9 is small. The distance on the plane to the vertical rod 11 is 900 mm +
The width is as wide as 200 mm = 1100 mm.

With such a configuration, the passage of a specific vehicle that passes while holding a low position such as a wheelchair or a stroller together with a person at a wide interval between the opposing lower horizontal bars 3 and 9 of the S-shaped passage. In this manner, it is possible to construct a gate that restricts the passage of a bicycle or a motorcycle by making the passage of a bicycle or a motorcycle difficult at a narrow interval between the opposing upper side bars 4 and 10 protruding from the lower side bars 3 and 9.

[0017]

According to the traffic-restricting gate of the present invention, the upper and lower horizontal rods formed of a substantially semicircular arc are extended from the upper horizontal rod to the lower horizontal rod. By forming a pair of curved fences that are connected in a state to face each other to form an S-shaped passage and standing upright, a wide space between the opposed lower horizontal bars that allows a wheelchair or a stroller to pass with a person The above-mentioned S-shaped passage is formed, and a person can stand and stand between the opposing upper horizontal rods. The S-shaped passages are formed at narrow intervals to make it difficult. The traffic-restricting gate of the present invention having such a configuration can be installed in a plaza, a park, or the like to restrict the traffic of the above-described specific vehicle, thereby ensuring safety.
