The mainspring spring 42 biases the housing cylinder 41b so that the double cylinder 41a rotates in the direction in which the belt 50 is wound.

The winding unit 20 constructed as described above
A is fixed to the upper end of the column 10 by fitting the lower end of the lower connecting portion 31 into the inner periphery of the upper end of the column 10 and fixing it by bolts, welding or other means.

The structure of the winding unit 20B is substantially the same as that of the winding unit 20A. However, the winding unit 20A is fixed to the column 10, while the winding unit 20B is fixed to the winding unit 20A. Is largely different from the winding unit 20A in that it is detachably and rotatably attached to the upper end of the winding unit 20A.

That is, the lower connecting portion 31 of the winding unit 20B has substantially the same inside diameter as the outer diameter of the upper connecting portion 33 of the winding unit 20A, and the outer periphery of the upper connecting portion 33 of the winding unit 20A. And is fitted so as to be freely inserted and removed and rotatably. Thus, the winding unit 20B is rotatably and detachably attached to the upper end of the winding unit 20A. In addition, a bolt 37 that penetrates the peripheral wall of the lower connecting portion 31 of the winding unit 20B is screwed into the lower connecting portion 31. The tip of the bolt 37 is connected to the winding unit 20A.
Annular engaging recess 3 formed on the outer peripheral surface of upper connecting portion 33

In the winding unit 20B, a head 38 is used instead of the upper connecting portion 33 of the winding unit 20A. The head 38 has the same configuration as the upper connecting portion 33 except that the engaging concave portion 33a is not formed and the upper surface has a spherical shape. Other configurations of the winding unit 20B are the same as those of the winding unit 20A.

FIG. 4 shows a specific example of the use of the fence post 1. The conventional fence post 1 having only one take-up unit is provided on the front, rear, left and right sides of the fence post 1. 'Is arranged. The belt 50 fed out from the winding unit 20A of the fence support 1 is locked to the fence support 1 'arranged on the right side of the fence support 1, and from the fence support 1' arranged on the left side. The fed-out belt 50 is locked to the fence support 1. Similarly, the winding unit 20 of the fence post 1
The belt 50 fed out from B is locked by the fence post 1 ′ arranged behind the fence post 1, and the belt fed out from the fence post 1 ′ arranged in front is engaged with the fence post 1. Has been stopped. As a result, the belt 50 extends forward, backward, left and right from the fence support 1. Note that the fence post 1 ′ used here is a winding unit 20 </ b> A of the fence post 1,
20B, the winding unit 20
Only B is fixed.

As is apparent from the above description, if the fence post 1 according to the present invention is used, it is sufficient to use only one fence post 1 to extend the belt 50 in two directions, front and rear, and left and right. There is no need to install two fence posts at the place where the fence posts 1 are installed. Therefore, the space utilization efficiency can be improved accordingly.

Further, in the fence support 1 of this embodiment, the belt 50 can be prevented from being largely bent by the entrance / exit 35 or the locking member 36.
That is, if the winding unit 20B is temporarily
A and the two winding units 20
Assuming that the entrance / exit portion 35 and the locking member 36 of A and 20B face the same direction, when the entrance / exit portion 35 and the locking member 36 of the winding unit 20A are oriented in the left-right direction, the winding unit 20B The entrance and exit portions 35 and the locking portions 36 also face in the left-right direction. However, the winding unit 20B
Since the belt 50 extends in the front-rear direction, as shown by imaginary lines in FIG.
At a right angle. As a result, the belt 50 is bent and the appearance is reduced, or the strength is reduced.

In this regard, in the above-described fence post 1, since the winding unit 20B is rotatably connected to the winding unit 20A, the entrance 35 and the locking member 36 of the winding unit 20B are provided. Can be directed in the front-rear direction regardless of the direction of the winding unit 20A. Therefore, it is possible to prevent the belt 50 from being greatly bent, and to prevent a reduction in the appearance and strength of the belt.

FIG. 5 shows a fence post 1A according to another embodiment of the present invention. In this fence post 1A, a lower connecting portion 31 of the winding unit 20B of the fence post 1 is used. , A lower connecting portion 31 'having a longer length is used. Other configurations are the same as those of the fence support 1 described above.

As described above, when the lower connecting portion 31 'having a long length is used, the two belts 50, 50 can be stretched vertically apart from each other. Therefore, by adjusting the height of the belt 50 of the lower winding unit 20A to the height of the child and adjusting the height of the belt 50 of the upper winding unit 20B to the height of the adult, both the adult and the child can enter the restricted area. Can be prevented from entering. In particular, in this embodiment, since the winding unit 20B is detachable, by appropriately replacing this with various winding units 20B having different lengths of the lower connecting portion 31 ', the two belts 50, The height difference of 50 can be set arbitrarily.

The present invention is not limited to the above-described embodiment, and the design can be changed as appropriate. For example, in the above embodiment, the lower take-up unit 20A is fixed to the column 10, but it may be detachably and rotatably attached in the same manner as the take-up unit 20B. In the above embodiment, the two winding units 20 are used.
Although A and 20B are provided in two upper and lower stages, one or more winding units 20A may be sequentially connected to the winding unit 20A, and the winding unit 20B may be further connected thereon. By doing so, the belt 50 can be stretched in three or more steps, and the belt 5 can be stretched in three or more different directions.
0 can be extended. Of course, also in this case, it is desirable that the second and subsequent winding units are detachably and rotatably connected.

[0023]

As described above, according to the first aspect of the present invention, it is sufficient to install one fence post, even if the strip is stretched from one place in a plurality of directions. There is no need to install a support post. Therefore, the space can be effectively used by that much. In addition, a plurality of strips having different heights can be provided, whereby it is possible to more reliably prevent entry into a restricted area or the like. Moreover, by attaching and detaching the units as necessary, the above-described various types of stretching of the strips can be adopted, and furthermore, the height difference of the strips can be arbitrarily set by replacing each unit. Is obtained. Further, according to the invention according to claim 2, an effect is obtained that the strip can be prevented from being bent.
