Japanese Examined Patent Publication No. 61-4923 Utility Model Registration No. 2595069 Specification

  The engagement between the groove on the upper peripheral edge of the conventional support column and the protrusion of the intrusion prevention rod is shallow, the intrusion prevention rod easily rotates with respect to the column, and the first and second positions are difficult to fix. Also, there are many accidents in which a child or the like turns, pulls out, or moves to another place as a play.

  In order to clearly establish the first and second positions, an attempt is made to deepen the groove at the upper edge of the opening of the column made of pipe material. However, it is preferable to deepen the groove because cracks are likely to occur in this portion. Absent.

  Therefore, this invention makes it the subject which should be solved to eliminate the malfunction of the prior art mentioned above.

  In order to solve the above-described problems, the present invention rotatably supports a support member that supports a sleeve member on a column having a pair of notch portions with drop portions, and penetrates the support member and the notch portion. Basic means for opening and closing the sleeve member by fixing the sleeve member to the rod and moving the rod along the notch is used.

  Employment of the technical means allows the rod to be fitted into the notch, has no backlash, and prevents the sleeve member from being pulled out from the column. In addition, fixing the support to the column is useful for preventing rotation and theft of the sleeve member.

According to the present invention, a column having a pair of opposed notches that are erected with respect to a road surface, and that includes a horizontal portion that extends in the circumferential direction on a side peripheral surface and a drop portion that extends downward in the axial direction from one end of the horizontal portion. And a support that has a top end closed, and a cross-sectional shape that corresponds to the shape of the opposing notch and the hole. A rod penetrating the notch and the hole, a sleeve member fixed to both ends of the rod , and an anti-rotation body for coupling the support and the support, and the rod is moved along the notch A vehicle passage prevention fence is provided in which the first position where the sleeve member is closed and the second position where the sleeve member is opened are respectively provided at both ends of the opposed notch .

Preferably, the second position of the sleeve member in the open when Rod has entered the drop unit.

  More preferably, when the rod is positioned at the other end of the horizontal portion, the sleeve member is held in the first position by the rotation preventing body.

  In addition, the support column is made of an aluminum alloy round pipe, the sleeve member is made of an aluminum alloy square pipe, and the support is made of an aluminum alloy shape.

Since the sleeve member moves the rod for fixing the sleeve member along the notch and establishes the open and closed positions at the end of the notch, there is no backlash of the sleeve member. Eliminating the vertical vibration of the sleeve member eliminates the vibration of the sleeve member due to wind or the like, and does not generate abnormal noise.
The sleeve member can be easily rotated by removing the anti-rotation body and allowing relative rotation between the support and the support column.

Since the anti-rotation body and the anti-theft body can be locked, an accident that the sleeve member is taken away can be prevented.
Assembling work at the site is easy because the sleeve member, the support and the support can be set in advance in the factory, and only the support is inserted into the sheath tube.
The taper of the horizontal part of the notch improves the sliding of the sleeve member, and the dropped part stabilizes the position of the sleeve member and is safe without moving the sleeve member only by touching the sleeve member.

As shown in FIG. 1, a preferable vehicle passage prevention fence 1 of the present invention includes a column 2 made of an aluminum alloy material, a support 4 that is rotatably fitted to the column and has a width across flats 3, and a column. 2 and at least a sleeve member 6 fixed to a rod 5 penetrating the support 4. The support 4 is made of an aluminum alloy material, and the sleeve member 6 is an aluminum alloy square pipe formed in a horizontal U shape. Preferably, several connecting rods 7 are fixed.
A lid 8 is screwed to the top opening of the support 4.

  As shown in FIG. 1, FIG. 4, and FIG. 5, a pair of notch portions 9 spaced apart from the upper and lower portions of the support column 2 are formed to face each other. The notch portion 9 includes a horizontal portion 10 having a taper of 2 degrees in the illustrated example, and a dropped portion 11 at one end of the horizontal portion 10, and the width thereof facilitates the movement of the rod 5 made of square material. A dimension is selected.

Square holes 15 are made above and below the upper and lower cutouts 9 of the column 2. These square holes 15 are used to attach the anti-rotation body 12 and the anti-theft body 13. A square hole having the same shape is formed in the portion of the support 4 facing the square hole 15. As shown in FIG. 1, in the case of the embodiment in which the support column 2 is inserted into the sheath tube 14 embedded in the road surface, the same shape square hole is formed in the sheath tube 14.
A square hole through which the rod 5 passes is formed in the width across flats 3 of the support 4.

  The drop portions 11 of the pair of notch portions 9 formed above and below the support column 2 face each other, and the rod 5 is moved in the axial direction to establish the open position of the sleeve member 6, that is, the second position. When the rod 5 is lifted and turned 90 degrees (angle) horizontally, the sleeve member 6 takes the closed position, that is, the first position. At this first position, the anti-rotation body 12 can be penetrated into the support body 4 and the support column 2 using the square holes 15 of the anti-rotation body 12, and the first position is established.

At the time of assembly, the support body 4 is fitted to the support column 2, and the two rods 5 are passed through the two-sided square hole and the notch portion 9 of the support column 2. The ends of the sleeve member 6 are screwed to both ends of the rod 5.
The rod 5, the sleeve member 6, and the support body 4 integrally rotate around the support column 2, but the movement is restricted by the movement in the notch 9 of the rod 5. That is, the closed position where the rod 5 is positioned at one end of the horizontal portion 10 of the notch 9 and the open position positioned at the dropping portion 11 at the other end of the horizontal portion 10 can be selected.

  The rod 5 is positioned at one end of the horizontal portion 10 of the notch portion 9 (position indicated by a solid line in FIG. 2), and the anti-rotation body 12 with a head is passed through the support body 4 and the square holes of the support column 2 to support the support body. The rotation with respect to the support | pillar 2 of 4 is blocked | prevented. Unless the lock 16 is applied to the anti-rotation body 12 (see FIG. 3), the sleeve member 6 is prevented from moving to the open position, that is, the position where the vehicle can pass. Preferably, such an assembly is shipped from the factory.

  The assembly shipped from the factory is inserted at the construction site into the lower part of the column 2 into the sheath tube 14 already embedded in the road surface, and the anti-theft body 13 penetrates the sheath tube 14 and the column 2. A lock 16 is put on the anti-theft body 13 to prevent the column 2 from coming off. Thus, the construction work is completed and the construction is very easy.
