DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence post constituting a fence.

[0002]

2. Description of the Related Art In many cases, entrances and exits of parking lots, parks and the like are provided with fences composed of pillars and chains. These fences are configured so that fence posts and chains can be easily attached and detached in preparation for daily traffic in and out of the parking lot and temporary events in parks and the like. That is, the fence poles constituting the fences are often used so that they can come and go from the inside of the basement box or can be pulled out and put in. Handrails such as chains that connect the fences are devised so that they can be easily connected to or removed from the fence posts.

[0003] Further convenient storage and storage of chains and the like,
A configuration in which the chain is stored in a pole has been proposed. In the configuration in which the chain is housed in the pole as described above, it is important that the chain can be smoothly pulled out from the pole. Fence posts having these functions include, for example, those disclosed in Japanese Utility Model Publication No. 3-51362 and Japanese Utility Model Publication No. 4-44653. In the fence post disclosed in Japanese Utility Model Publication No. 4-44653, a chain is accommodated in a pole, and a ring is provided at one end of the chain. The pole is, of course, provided with a window hole for extracting the chain. And in the configuration of Jitsuhei 4-44653,
An empty space formed by a partition wall is provided inside the window of the pole so that the chain can be smoothly extracted, and a through hole through which only the chain can pass is provided on the bottom surface of the empty room. . Therefore, when the chain is stored, the ring of the chain remains in the empty room inside the pole, and any other part of the chain falls into another part of the pole. Therefore, the user can pull out the inner chain by inserting his finger into the hole on the side of the pole and pulling out the ring.

On the fence post of Japanese Utility Model No. 4-44653,
As a means for connecting a chain in another fence post to the fence post, a ring locking hole is provided. A lock is provided inside the ring locking hole, and the engagement of the ring is maintained by operating the operation unit. 3-51362

[0005]

The fence post of the prior art is characterized by having an empty room surrounded by a partition wall. As described above, only the ring remains in the empty room when the chain is stored. Therefore, the user can pull out the chain by pulling out the ring. Also, at that time, the chain smoothly escapes without getting caught anywhere. As described above, the fence post of the related art is easy to use and has an excellent configuration. However, prior art fence posts suffer from the difficulty of assembly.

That is, in the fence post of the prior art, it is necessary to provide an empty room surrounded by a partition on the inner surface of the window hole inside the pole. By the way, in general, the fence post has a window hole for extracting a chain slightly below the top of the pole due to design requirements and the need to provide an umbrella-shaped lid on the head. Therefore, in order to provide a vacant space in the window hole at that position, it is necessary to attach a vacant space made of a partition wall at a position slightly deeper from the end face of the pole. This is often done by welding. However, since the diameter of the pole is generally small, the welding operation of the vacant room is difficult. Further, since the thickness of the pole is generally thin, a depression or the like may be formed on the outer surface by welding the inner surface of the ball.

Further, the conventional fence post has a problem that it takes time and effort to connect a chain in another fence post to the fence post.

And a connecting portion 15 that engages with the body. The locking piece holding plate 16 employed in the present embodiment is obtained by pressing a single plate, cutting the die, and then bending the plate at a bending angle of about 100 °. The shape of the retaining piece holding plate 16 is composed of a vertical wall 18 for attaching to the support 30 and a supporting wall 20 for actually supporting the retaining piece 4 of the chain 5. In this embodiment, the end surface of the support wall 20 has an arc shape. The curvature of the arc of the end face is the same as the inner circumference of the pole 3. Therefore, the support wall 20 of the locking piece holding plate 16 can be brought into contact with the inner wall of the pawl 3. A hole 21 is provided in a portion near the end face of the support wall 20. The size of the hole 21 is such that the chain 5 can easily pass through, but the locking piece 4 cannot pass through.

On the other hand, the connecting portion 15 comprises a support 30, a bearing member 31, a cam 32, a cam follower 33, a pin 35, a spring 36, and a pin bracket 37. Among the above-mentioned constituent members, the support 30 is a groove-shaped frame-shaped member as shown in FIG. 4, and one end portion, more specifically, a portion corresponding to the lower end in the attached state is a groove. Is folded inward. And the part concerned is fixed part 4
Functions as 0. The support 30 is provided with a shaft hole 43 for supporting the cam 32. The bearing member 31
The support 30 is mounted in a protruding manner in the groove of the support 30.
A shaft hole 45 is provided in the same axis line as the shaft hole 43 of FIG.

As shown in FIGS. 4 and 5, the cam 32 has a rod-shaped cam body 48 attached to a rotating shaft 47. As shown in FIG. The rotating shaft 47 is provided with a slit through which a key (not shown) is inserted. The cam follower 33 is an “L” -shaped member, and has a long hole 50 at the center.
The pin 35 has a columnar shape, and the tip is a slope. The small pin 51 is orthogonal to the position below the pin 35. The pin bracket 37 is a groove-shaped member, and is mounted in the groove of the support 30 in a direction perpendicular to the groove of the support 30.

In this embodiment, the connecting portion 15 is
It is assembled around. The support 30 serving as the center of the connecting portion 15 has a U-shaped end face at the upper end welded to the inner face of the upper end of the pole 3, and the support 30 is integrally attached to the inner face of the pole 3. ing. The cam 32 is inserted into a shaft hole 43 of the support 30, a shaft hole 45 of the bearing member 31, and a hole 50 of the cam follower 33, and is rotatable. By rotating the cam 32, the cam body 48 can abut on the inner surface on the short side of the cam follow 33. On the other hand, the pin 35 is
Is inserted through the hole. A spring 36 is attached to the pin 35. Both ends of the spring 36 are
The pin 35 is in contact with the inner surface of the pin bracket 37 and urges the pin 35 toward the fixing portion 40. The lower end of the cam follower 33 is attached to the upper end of the pin 35.

The vertical wall 18 of the locking piece holding plate 16 is in contact with the back surface of the support 30 and is integrally attached to the support 30 by a stud 53. Further, the end surface of the support wall 20 of the locking piece holding plate 16 has an arc shape, and since this curvature coincides with the inner surface of the pole 3, the end surface of the support wall 20 contacts the inner surface of the pole 3. Whether to weld the end of the support wall 30 and the inner surface of the pole 3 is optional, but it is not usually necessary to weld this part. The chain 5 is housed in the pole 3 with the locking piece 4 at the tip being outside the support wall 20.

Although the procedure for assembling the fence post 1 of the present invention is optional, the recommended procedure is to integrate the connecting portion 15 and the locking piece holding plate 16 beforehand outside the pole, and to integrate them together. Insert it into the pole as it is, and
And the inner surface of the pole 3 is preferably electrically welded. Since this welding operation is performed at the open end of the pole 3, it is easy. The welded portion is a portion that is hidden by the cover 7 and hardly visible from the outside when the cover 7 is attached to the top of the pole 3. The adverse effect of is small.

Next, the operation of the fence post 1 of this embodiment will be described. The fence post 1 of this embodiment is used by setting up a pole 3 on a basement box 2 as shown in FIG. Then, when it is not necessary to stretch a handrail between the fence poles 1 as in the case where a car is passed continuously, the entire chain 5 is stored in the pole 3. Chain 5
Is stored, the main body of the chain 5 falls to the bottom of the pole 3, but only the locking piece 4 remains on the support wall 20.

When the chain 5 is stretched between the fence posts 1, the retaining piece 4 remaining in the hole 10 is picked up. Then, the chain 5 is sequentially extracted from the pole 3. In the fence post 1 of the present embodiment, the pole hook 8 hangs in the space above the support wall 20,
Although the site is not an “vacancy” as in the prior art, the site is considerably large so that the pole hook 8 does not hinder the extraction of the chain 5. In addition, the length of the back surface of the support 30 in the diameter direction of the pole is smaller than the width of the vertical wall of the locking piece holding plate 16, so that the space above the support wall 20 is
Although not partitioned by a partition, the area of the support wall 20 is sufficiently large, and there is no case where a portion where the chain 5 is kinked goes around the upper side of the support wall 20, so that the chain 5 can be smoothly pulled out.

The connecting piece 15 of the adjacent fence post 1 has a locking piece 4
Connect. In this embodiment, the procedure for connecting the locking pieces 4 simply requires pushing the locking pieces 4 into the elongated holes 11. That is, when the locking piece 4 is pushed into the elongated hole 11, the inclined surface of the pin 35 comes into contact with the locking piece 4, and the pin 35 receives an upward force. Then, the pin 35 escapes upward against the spring 36, and the locking piece 4 passes through the pin 35. Then pin 35
Is returned to the original position by the spring force and engages with the locking piece 4. Since the surface of the pin 35 engaging with the locking piece 4 is vertical, simply pulling the chain 5 does not cause the locking piece 4 to come off.

In the fence post 1 of this embodiment, the locking piece 4 is
Since the locking piece 4 is connected by being pushed into the connection piece 1, the connecting portion 15 receives a diametrical force in the pole 3. However, the fence post 1 of this embodiment
Since the support wall 20 of the locking piece holding plate 16 has an arc shape and this end surface contacts the inner surface of the pole 3,
Force in a diameter direction as described above is loaded on the inner surface of the pole 3 via the locking piece hold plate 16. Therefore, no bending moment acts on the support 30 itself, and the support 30 does not come off the inner surface of the pole 3.

When removing the locking piece 4, a key (not shown) is engaged with the hole of the cam 32, and the cam 32 is rotated.
Then, in the cam 32, the cam body 48 pushes up the cam follower 33, and the pin 35 rises. As a result, the engagement between the pin 35 and the locking piece 4 is released.

[0036] The above-described stanchion 1, the engagement piece retain plate 16
Has been fixed to the back of the support 30, it is also possible to fix the locking piece hold plate 16 as in Figure 8 In addition to the bottom surface of the support 30. The shape of the locking piece is not limited to a ring shape, but may be a hook shape or a plate with a hole. Hole 21 provided in the locking piece hold unit 16, by engaging together the engaging piece 4 is smoothly passed through the chain 5, the function of the engaging piece 4 is prevented from falling into the pole 3 The same function can be achieved by using a groove having one end opened in place of the hole. The most common handrail material is a chain as employed in the present embodiment, but a wire, a rope, or the like may also be used.

[0037]

In the fence post according to any one of the first to sixth aspects, the locking piece of the handrail is supported by the locking piece holding plate in the pole, so that the locking piece does not fall into the pole. There is no. Further, since the locking piece holding plate is attached to the support of the connecting portion, it is not necessary to weld the connecting portion to the inner surface of the pole. Therefore, the fence post of the present invention has an effect that assembly is easy. In the fence post of the present invention,
Is the upper end of the pole where the connecting part is attached
Part, and an umbrella-shaped lid on the top of the pole
Since it is provided, deformation of the welded part is hidden behind the lid and
It is hard to see from the part. Therefore, there is little adverse effect on the appearance.

According to the second aspect, since the support is frame-shaped, the rigidity of the support is high and the fixing state of the locking piece holding plate is more firm.

Further, in the fence post according to the third and fourth aspects, the retaining piece holding plate is in contact with the inner surface of the pole, so that the axial force received by the support is applied to the pole via the retaining piece retaining plate. Supported by Therefore, the fence post of the present invention has an effect of high attachment rigidity of the connecting portion, the locking piece holding plate, and the like.

In the fence post according to the fifth and sixth aspects, since the pin, the cam follower and the cam are mounted on the support, there is an excellent effect that the mounting rigidity is high.

Further, the fence post according to the fifth and sixth aspects is easy to assemble, exhibits high rigidity without damaging the outer shape of the pole, and is easy to attach and detach handrails.
