Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device mainly used for restricting the entry and exit of cars in a parking lot or restricting the passage of cars on a road. and a columnar body that fits into the cylindrical body, a receiving part on which the columnar body is placed is provided inside the cylindrical body near the upper end, and an upright columnar body is provided near the bottom end of the columnar body. The present invention relates to an improvement in an overturning and retractable traffic restriction device that is provided with a lower abutting part that supports a body by abutting against the receiving part, and an upper abutting part that supports an inverted columnar body by abutting against the receiving part.

As the above-mentioned traffic restriction device, the one shown in Fig. 4 (see Japanese Patent Publication No. 7378/1986) was proposed earlier, but there was room for improvement in terms of preventing slippage and preventing shaking when standing up. That is, the lower end side of the columnar body B is provided with the enlarged root portion 21 that forms the lower and upper contact portions, and the upper end side of the cylindrical body A is provided with the holding cylinder 22 into which the enlarged root portion 21 is fitted. A receiving part 4 is provided at the lower end of the holding cylinder 22, and the columnar body B is placed in an upright state as shown in FIG. 4A, and the columnar body B is stored upside down as shown in FIG. 4B. However, in either state, the columnar body B could be removed by simply pulling it up, causing problems such as traffic restrictions not being observed and the columnar body B easily becoming powdered. Furthermore, in order to facilitate the insertion and removal of the columnar body B, the precision of the fitting between the enlarged root portion 21 and the holding tube 22 cannot be made very high, resulting in the problem that the columnar body B tends to sway when standing up.

An object of the present invention is to make it possible to prevent the column from slipping off and from swinging effectively at the same time by simple and rational modification.

A characteristic configuration of the present invention is that in the above-mentioned traffic restriction device, the first square plate serving as the lower contact portion is
Formed so that the outer peripheral edge shape is approximately square,
A second rectangular plate is attached to the lower end of the columnar body substantially concentrically and serves as the upper contact portion.
The square plate is formed so that its outer peripheral edge shape is approximately the same size and the same shape, and is attached to the columnar body approximately concentrically and with a corner direction different from that of the first square plate. A rectangular tube having a shape and size that allows the first and second rectangular plates to be fitted and slid inside the body is attached above the receiving portion so as to be substantially concentric with the cylindrical body; A gap is formed between the lower end of the cylinder and the receiving part, into which the corners of the first and second plates can move vertically, and the distance between the square plates is equal to the length of the square cylinder. The distance between the upper end of the rectangular tube and the receiving portion is smaller than the distance between the upper end of the rectangular tube and the receiving portion.

That is, according to the above-mentioned characteristic structure, as shown in FIG. When the columnar body B is turned without being inserted, the corner 8a of the first square plate enters into the gap 7, and when the second square plate 10 is then fitted into the square tube 6, the first square plate 8 is placed on the receiving part 4. Therefore, even if the columnar body B is simply pulled upward, the columnar body B will not come out due to the contact between the first square plate 8 and the square tube 6. figure,
Moreover, the fitting between the second square plate 10 and the square tube 6 sufficiently prevents the columnar body B from swinging.

In addition, when storing the columnar body B upside down, as shown in FIG. When the columnar body B is turned, the corner 10a of the second square plate 10 enters the gap 7, and then when the first square plate 8 is fitted into the square tube 6, the second square plate 10 fits into the receiving part 4. Therefore, even if the columnar body B is simply pulled upward, the columnar body B will not come off due to the contact between the second square plate 10 and the square tube 6.

As a result, it is possible to effectively prevent the inconvenient situation in which the columnar body is pulled out when standing up and traffic restrictions are not observed, and the columnar body can be firmly erected with less shaking, resulting in an excellent We were able to equip it with a traffic restriction function. Furthermore, since the columnar body does not easily fall out either when standing up or storing it, it is possible to effectively prevent the inconvenient situation of the columnar body being lost due to mischief, etc., and the overall product value is extremely high. A high traffic restriction device was obtained.

Next, examples will be shown.

As shown in Figure 1, a cylindrical body A is buried under the road surface GL, and a columnar body B is fitted upright on the top of the cylindrical body A to form a device for restricting vehicle traffic, etc. .

In the cylindrical body A, a large diameter cylindrical part 3 is arranged approximately concentrically with each other on the upper part of a small diameter cylindrical part 2 having a drainage hole 1, and a columnar body is arranged at the boundary between the two cylindrical parts 2 and 3. A rectangular cylinder 6 with a lid 5 and a substantially square shape is provided almost concentrically within the large diameter cylinder part 3, and the lower end of the rectangular cylinder 6 and the receptacle part 4 are formed. A gap 7 is formed between them.

In the columnar body B, a first rectangular plate 8 serving as a lower contact portion that supports the columnar body B that stands up by contacting with the receiving portion 4 is provided approximately concentrically at the lower end portion of the columnar body 9. A second square plate 10 is provided above the square plate 8 so as to be substantially concentric with the column body 9,
As shown in FIG. 3, the second rectangular plates 8 and 10 are formed so that their outer peripheral edges are approximately square so that they can be inserted into and removed from the rectangular tube 6, and have approximately the same size. are installed so that they are different. and the first and second square plates 8,
10 is set to be larger than the length l ₂ of the square tube 6 _and smaller than the distance l ₃ between the upper end of the square tube 6 and the receiving part 4, and the first and second square plates 8, 10 is made smaller than the width of the gap 7, the first square plate 8 is inserted to the bottom of the square tube 6, and the columnar body B is inserted with the second square plate 10 not inserted into the square tube 6. When rotated, the corner 8a of the first square plate 8 will move into the gap 7.
When the second square plate 10 is inserted into the upper part of the square tube 6, the first plate 8 is placed on the receiving part 4. Also, the first
A pin 11 attached to the receiving part 4 on the square plate 8
A fitting hole is formed for the first rectangular plate 8 so that the columnar body B cannot be rotated without being lifted.
The columnar body B is effectively prevented from coming off by the contact with the rectangular tube 6.

A reflective tape 12 is attached to the upper end side of the columnar body B, and a connecting pin 13 and an insertion hole 14 for a chain etc. are provided, and a sealing material 15 is provided near the first square plate 8.

As shown in FIG. 2, the cylindrical body A is formed to have a length that allows the columnar body B to be stored upside down, and when the columnar body B is stored in an inverted state, the second square plate 10 is The first rectangular plate 8 is placed on the receiving part 4 as an upper abutting part for supporting the cylinder, and is fitted onto the pin 11, and the first rectangular plate 8 is fitted to the upper part of the rectangular tube 6 as a lid. . and,
A handle 18 is attached to the first square plate 8 so as to be able to move in and out of the recess 16 of the plate 8 and urged toward the retracting side by a spring 17.

Next, another example will be shown.

The shapes of the cylindrical body A and the columnar body B can be changed as appropriate.

To form the receiving portion 4, various other configuration changes are possible, such as welding a ring to the inside of the cylindrical body A.
