Description

[Detailed Description of the Invention] The present invention provides, for example, a fence post in a car stop fence constructed by connecting the upper ends of a plurality of fence posts erected at appropriate intervals with ropes, chains, rods, etc. Specifically, a lid body is attached to the upper end of the cylindrical fence post body, and the lid body is inserted into a pair of upper and lower through holes formed in the lid body so as to be vertically movable. A rope insertion hole is formed by inserting both the long and short rod-like parts into the through-hole, and the long and short rod-like parts are provided with a connecting rod-like part whose upper ends are fixedly connected to each other. By inserting only the rod-shaped portion into the through-hole, a rope hook is provided in a manner that prevents the rope from coming out, forming a rope entrance and exit for opening the rope insertion hole laterally between the lower end of the short rod-shaped portion and the top surface of the lid body. Regarding fence posts.

In this type of fence post, by pulling up the rope hook, the rope insertion hole is opened to the side, and the middle part of the rope can be attached to and detached from the rope hook from the side. It has the advantage that it is not necessary to pass the rope through the rope insertion hole from the end one by one, and the work of inserting and removing the rope from the rope hook is very advantageous. When fixedly attached to the fence post body, the rope insertion direction for the rope hook is determined by the anchorage of the fence post body to the ground, so it is possible to match the rope insertion direction for the rope hook on multiple fence posts. In order to do this, when fixing each fence post body to the ground, it is necessary to fix the fence post body accurately and precisely so that the rope insertion direction of the rope hook is in the desired direction. The disadvantages are that it takes time to establish and the workability is poor.

The purpose of the present invention is to overcome these conventional drawbacks.

The characteristic structure of the fence post according to the present invention taken to achieve the above object is that the lid body is configured to be rotatable around the vertical axis relative to the fence post body,
The operation of the present invention having such a characteristic configuration is as follows.

That is, by rotating the lid, the rope hook can be rotated with respect to the fence post body, and the rope can be inserted in any direction within 360 degrees around the fence post body.

Therefore, the present invention allows the fence post main body to be fixed on the ground without considering the rope insertion direction of the rope hook, and by rotating the lid body after the fence post main body is fixed. , the rope insertion direction of the rope hanging can be made in the desired direction, and the rope insertion direction of the rope hanging of multiple fence posts can be matched as a whole, while each fence post main body can be easily and quickly It has achieved the following effects: it can be firmly fixed and has superior workability.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in Figure 1, a plurality of fence posts A are erected on a concrete foundation B at appropriate intervals, and a rope C is removably strung between the fence posts A. and form a fence such as a vehicle stop fence.

The fence post A is constructed by attaching a lid 2 to the upper end of a cylindrical fence post main body 1 made of a steel pipe or a vinyl pipe, and attaching a rope hook 3 through which a rope C is passed through the lid 2. ing.

The mounting structure of the lid body 2 to the fence post body 1 uses a round bar to place the lid body 2 near the upper end of the inner peripheral surface of the fence body 1 so as to be rotatable around the axis a of the fence post body 1. While fixing the lid mounting ring 4 to the lid body 2,
A member 5 that comes into contact with the lower surface of the lid mounting ring 4 to prevent the lid 2 from moving upward is fixed, and the lid 2 is rotated around the axis a of the fence post body (an example of the vertical axis). It has a structure that allows it to be mounted freely. Therefore, the rope hook 3 is rotatable around the axis a of the fence post body.

The rope hook 3 includes two long and short rod-like portions 3a and 3a' that are vertically movably inserted into a pair of upper and lower through-holes 6 and 6' formed in the lid body 2, respectively, and these rod-like portions 3a and 3a'. A rope insertion hole 3A is formed by inserting both the long and short rod-like portions 3a, 3a' into the through holes 6, 6'. By inserting only the short rod-like portion 3a into the through hole 6, a rope entrance/exit 3B is formed between the lower end of the short rod-like portion 3a' and the lid body 2 to open the rope insertion hole 3A laterally. A nut 7 for preventing upward removal is screwed onto the lower end of the elongated rod-like portion 3a, and between the nut 7 and the lid 2, the elongated rod-like portion 3
In other words, a coil spring 8 is interposed to move and bias the rope hook 3 downward. Further, the three rod-shaped portions 3a, 3a', and 3b are formed into a series by bending a single rod-shaped body, and the long rod-shaped portion 3a and the corresponding through hole 6 are as follows: In order to prevent the long rod-like portion 3a from rotating around its axis b when the short rod-like portion 3a' is extracted upward from the through hole 6', it is configured in a square rod shape and a square hole shape. There is. Therefore, without aligning the short rod-shaped portions 3a' with the through holes 6',
The short rod-shaped portion 3a' can be inserted into the through hole 6'. In addition, the connecting rod-shaped portion 3b is formed into a round rod shape so that it can be easily held.

In addition, the fence post body 1 is divided into an upper part 1A and a lower part 1B for assembling the lid, which are welded to each other, in order to enable the installation of the lid 2 with the rope hook 3. The body 2 is formed with a connecting rod-like portion 3b of the rope hook 3, a recess 2A for storing the connecting rod-like portion 3b so as not to protrude upward when it is located below, and a recess 2B for storing the lower half portion of the insertion rope B. ing.

According to the configuration of the above embodiment, no matter what posture the fence post main body 1 is fixed in around the axis a, the rope insertion of the rope hook 3 can be performed by rotating the lid body 2 around the axis a. The direction can be made parallel to the fence posts, and by pulling up the rope hook 3, instead of inserting the rope B into the rope hook 3 from the end, the rope hook 3 at the middle part of the rope B can be inserted.
The rope B can be inserted through the rope hook 3 by inserting it from the side.

Incidentally, the present invention may be implemented as listed below.

As shown in FIG. 4, the lid body 2 is configured to be flat.

In the embodiment described above, the coil spring 8 is removed and the long rod-shaped portion 3a is stopped by the nut 7.

In the above embodiment, the elongated rod-shaped portion 3a is configured to be rotatable around its axis b. Specifically, the elongated rod-like portion 3a is formed into a round rod shape, and the through hole 6 is formed into a round hole shape. Furthermore, the fence posts to which the present invention is directed include those that can be switched between a state protruding above the ground and a state retracted below the ground by vertically sliding or vertically swinging.
