DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence post in which a post rises and falls from a cylindrical underground box buried underground, and more particularly to a fence post in which the raised post does not rattle. .

[0002]

2. Description of the Related Art There are non-fixed fence posts installed at entrances and exits of parks, entrances and exits from public roads to private roads, entrances and exits of parking lots, and the like, which prevents and allows vehicles to enter by hour. As shown in FIGS. 4 and 5, the non-fixed fence post includes a cylindrical basement box 110 buried underground and a support 12.
There is an embedded type where 0 goes up and down. Recessed fence post basement box 11
0 is slightly longer than the support 120, and the support 120 can be immersed in the underground box 110 when the support 120 is lowered. The inner diameter of the basement box 110 is
Is slightly larger than the outer shape of the support box 120, and a clearance is provided between the inner surface of the basement box 110 and the outer surface of the support column 120 so that the support column 120 can move up and down inside the basement box 110 smoothly. In order for the raised support 120 to be held in the raised position, a pin 12
1 is protruded.

Further, the upper end opening 111 of the basement box 110
Has a cylindrical guide 130 for holding the support 120.
Is attached. The inner diameter of the guide 130 is substantially the same as the outer shape of the column 120, and a flange 131 is formed at the upper end of the guide 130. Screws (not shown) are screwed to the upper end surface of the basement box 110 from four places of the flange 131, and the guide 130 is fixed to the upper end opening 111 of the support 120. At the lower end of the guide 130, a guide groove 132 for introducing a pin 121 projecting from the lower part of the support 120 is formed, and a locking portion 133 for locking the pin 121 is formed at the back of the guide groove 132.

On the other hand, a support post 120 has a hook 122 on its upper end surface.
Is mounted so that it can come and go. When the vehicle is allowed to enter and the column 120 is lowered and stored in the underground box 110, the hook 122 is sunk into the column 120 so as not to hinder running and walking. To prevent entry of the vehicle, an operator picks up the hook 122 and raises the support column 120 from inside the basement box 110. Then, as shown in FIG. 5 , when the pin 121 projecting from the lower part of the support 120 is introduced into the guide groove 132 of the guide 130 and locked by the locking portion 133, the support 120 keeps its raised position.

[0005] The reflection seal 1 is provided on the upper part of the support 120.
May be stuck. If the reflective seal 1 is simply stuck to the surface of the support 120 having a uniform outer diameter, when the support 120 is moved up and down into the basement box 110, the reflective seal 1 is rubbed against the inner surface of the guide 130 and peeled off. Resulting in.
For this reason, Japanese Utility Model Publication No. 63-43221 discloses that
By forming a concave portion on the surface of the support 20 and attaching the reflective seal 1 to the concave portion, the surface of the reflective seal 1
There is disclosed a fence post that is located inside the surface of the fence.

[0006]

The support 120 and the guide 1
If there is almost no space between the support 30 and the guide 130, dust or the like enters between the support 120 and the guide 130, and the support 120 cannot be moved up and down from the basement box 110. Therefore, a clearance is provided between the support 120 and the guide 130.

However, if a clearance is provided between the support 120 and the guide 130, the raised support 120 will not be firmly held by the guide 130, and the support 120 will rattle. Slightly inclined and felt unstable. In addition, when several other fence posts are arranged, there is also a problem that the posture is likely to be uneven and the appearance is deteriorated when the support 120 is loose.

Accordingly, an object of the present invention is to provide a fence post in which a post raised from an underground box is held without rattling.

[0009]

A first means for achieving the above object is a guide having a cylindrical basement box and a locking portion.
And a support, and the guide is provided on the inner surface of the upper end of the basement box.
Attached, the column can go up and down the basement box through the guide
Is inserted and the support is held in the raised position by the locking portion of the guide.
In the fence post to have, a bulge is formed at the lower edge of the support,
Further, an enlarged diameter portion is provided at a portion above the bulging portion.
The basement box has a tapered inner surface that reduces the diameter from the middle to the opening.
The support has a raised surface, and the bulging portion is in
The abutment with the tapered surface, and the enlarged diameter part of the column is the inner surface of the guide.
It is a fence post characterized by being in contact with .

A second means for achieving the above object is as follows:
The fence post according to the first means, wherein a strip-shaped reflection sticker is attached to the support, and ridges are provided on both sides of the reflection seal.

[0014]

According to the above means, the bulge is formed at the lower end edge of the support and the tapered surface is formed on the inner surface of the basement box. The formed bulge contacts the reduced diameter part of the basement box,
The struts are held without rattling.

If the reduced diameter portion is a tapered surface,
The bulge rises along the tapered surface and the strut is more securely held.

According to the above-described means, the enlarged diameter portion projects from the lower portion of the column, so that when the column moves to the raised position, the enlarged diameter portion contacts the guide, and the column is held without rattling.

According to the above means, when the column is raised to the raised position, the bulge formed at the lower edge of the column comes into contact with the tapered surface formed on the inner surface of the basement box, and protrudes below the column. Since the enlarged diameter portion contacts the guide, the support is held at two or more places, and the support raised from the basement box is held in a more stable state.

According to the above-mentioned means, the reflective seal is stuck slightly buried between the ridges on both sides. Therefore,
The reflective seal does not rub against the underground box when the column is raised or lowered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described with reference to FIGS. 1 (a), (b) and FIG. FIG. 1A is a cross-sectional front view of a fence post according to the present invention, and FIG. 1B is an enlarged cross-sectional front view of a main part of FIG. 1A. FIG. 2 is a perspective view of a lower end portion of a pillar of the fence post of FIG. 1 and a guide. FIG.
It is an AA line sectional view of (a) and (b).

In the fence post according to the present invention, the post 20 is inserted into the cylindrical basement box 10 so as to be able to move up and down, as in the conventional case. In the lower part slightly above the bulging part 21, two enlarged diameter parts 2 are provided.
2, and a tapered surface 11 is formed on the inner surface of the basement box 10 to reduce the diameter from the middle to the upper end.

A bulging portion 21 formed at the lower edge of the column 20
It is assumed that, for example, a thick ring is externally fitted to the lower end edge of the column 20, and screws are screwed into four places to form the column 2.
Fix to 0. The material of the bulging portion 21 is not particularly limited, but it is desirable that the bulging portion 21 be capable of elastic deformation to some extent and have excellent sliding characteristics. From this viewpoint, a resin is recommended.

The enlarged diameter portion 22 slightly above the bulging portion 21 is formed in a thin ring shape, and is provided at a lower portion of the column 20 so that the column 20 comes into contact with the inner surface 31 of the guide 30 when the column 20 moves to the raised position. It protrudes at two places with the pin 23 interposed. The diameter of the enlarged portion 22 is equal to the inner diameter of the guide 30 described later,
Therefore, it is considerably smaller than the inside diameter of other parts of the basement box 10. As a method of forming the enlarged diameter portion 22, other than a method of attaching a ring in the same manner as the above-described bulging portion 21, a method of plastically deforming the column 20 by pressing a roll against the inner surface of the column 20 is possible. A band-shaped reflective seal 1 is adhered to the upper part of the support 20, and ring-shaped ridges 1 are provided on both upper and lower sides of the reflective seal 1.
2 is protruded. The ridge 12 is formed by pressing a roll against the inner surface of the column 20 to plastically deform the column 20.

The tapered surface 11 of the basement box 10 is attached to the inside of the upper end of the basement box 10 in which the lower side where the inner diameter is enlarged is considerably larger than the bulging portion 21 of the column 20 and the upper side where the diameter is reduced. It is assumed that the outer diameter of the guide 30 matches the outer diameter of the cylindrical guide 30. The inner diameter of the tapered surface 11 gradually decreases from the lower side to the upper side,
0 moves to the raised position, the bulging portion 2
1 and the tapered surface 11 of the basement box 10 are brought into contact with each other.

As shown in FIGS. 2 and 3, the cylindrical guide 30 mounted in the upper end of the basement box 10 has a corrugated inner surface 31 and a plurality of ridges 32 projecting toward the center. The space S is provided between the support 20 and the concave streak 33 which is in contact with the enlarged diameter portion 22 of the guide 20 and is depressed on the inner surface 31 of the guide 30. Also, the ridges 32 projecting from the inner surface 31 of the guide 30 and the ridges 12 projecting from both sides of the reflection seal 1 are provided.
So that the pillars 20 can move up and down in the basement box 10 on which the guides 30 are mounted without the protrusions 12 being caught by the guides 30.

The fence post according to the present invention is constructed as described above. Next, the method of use will be described. To prevent the traffic of the vehicle, the support 13 immersed in the basement box 10 is raised by grasping the hook 13. At this time, since the projections 12 are provided on both sides of the reflection seal 1, the reflection seal 1 is not rubbed against the inner surface 31 of the guide 30 and thus does not come off. In addition, a bulging portion 21 protruding from a lower end edge of the support 20 is provided.
Does not contact the inner surface of the basement box 10 from the lowermost end of the basement box 10 to the lower side of the tapered surface 11. Further expanding part 2
2 is below the guide 30 and both are not in contact. Therefore, the column 20 rises smoothly.

When the column 20 approaches the ascending position, the pin 23 projecting from the lower portion of the column 20 engages the guide groove 3 of the guide 30.
Bulge 21 formed at the lower edge of the support 20
Is introduced into the tapered surface 11, and the enlarged diameter portion 22 protruding from the lower portion of the column 20 is introduced into the guide 30.
When the column 20 reaches the raised position, the pin 23 protruding from the lower portion of the column 20 is brought into contact with the guide groove 34 formed in the guide 30.
Is locked by the locking portion 35 at the back of the head. At the same time, the bulging portion 21 formed at the lower end edge of the column 20 comes into contact with the tapered surface 11, and the enlarged diameter portion 22 projecting from the lower portion of the column 20 comes into contact with the corrugated ridge 32 formed on the inner surface 31 of the guide 30. Touch Therefore, even if the strut 20 protrudes long from the basement box 10, the bulging portion 21 formed at the lower end edge forms the tapered surface 11 of the basement box 10.
, And the two enlarged diameter portions 22 projecting from the lower portion come into contact with a large number of projecting ridges 32 projecting from the inner surface 31 of the guide 30, so that the column 20 is held at three lower positions, The posture protruding from the basement box 10 is maintained without rattling.

The vehicle 20 is allowed to enter, and the strut 20 is
In order to be immersed in the support column 20, the hook 13 attached to the upper end surface of the support column 20 is grasped, and the pin 23 projecting from the lower portion of the support column 20 is released from the locking portion 35 of the guide 30. Since the tapered surface 11 of the underground box 10 is enlarged in diameter from the upper side to the lower side, the swelling portion 21 formed at the lower end edge of the column 20 is not rubbed by the tapered surface 11, and the column 20 is weighted by its own weight. Descending inside. In addition, since the clearance between the outer circumference of the support 20 and the inner circumference of the underground box 10 is relatively large, the support 20 smoothly enters the underground box 10.

When the support 20 moves up and down in the basement box 10, the reflective seal 1 attached to the upper part of the support 20 is protected by the ridges 12 on both sides of the reflective seal 1 and is rubbed against the inner surface 31 of the guide 30. Therefore, the reflection seal 1 does not peel off. Therefore, the column 20 protruding from the basement box 10 can be reliably recognized by the driver of the vehicle by the reflective seal 1.

The present invention is not limited to the above embodiment,
Design changes can be made within the spirit of the invention. For example, the bulge formed at the lower end of the column or the enlarged portion protruding at the bottom of the column is not limited to a ring shape. The present invention can be similarly carried out even if the inner surface is brought into contact with the inner surface. Further, in the case of a fence post in which only a bulging portion is formed at the lower edge without protruding the enlarged diameter portion at the lower portion of the column, it is not always necessary to attach the guide to the upper end opening of the basement box. Further, the basement box can be applied to a type in which a lid is pivotally attached to the upper end edge of the opening, and the column can be applied not only to an inverted U-shape but also to an I-shape. The reduced diameter portion of the basement box 10 is preferably tapered as in the present embodiment, but may be stepped.

[0031]

According to the invention described in claim 1 or 2 ,
By protruding the bulging part and the protruding part on the column, the column protruding from the basement box is held without rattling, there is a sense of stability even if the column is touched, and when a large number of fence columns are arranged, The posture does not become uneven and the appearance does not deteriorate.

According to the second aspect of the present invention, since the projections are formed on both sides of the reflection seal, the reflection seal is not rubbed against the inner surface of the basement box and peeled off. It is possible to maintain the prevention of rear-end collision.
