DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net support column, and more particularly to an improved mooring device for a net suspension support line in a net support column used for badminton, soft volleyball and Indiana.

[0002]

2. Description of the Related Art Nets used for badminton, soft volleyball and Indiana are shown in FIG.
A net support column 21 extending vertically at a predetermined height from the coat surface FL is used, and an upper cap 22 is provided at a head end thereof.
The upper cap 22 is provided with a guide groove (or a pulley rotatably fixed in the guide groove) for slidingly guiding a net suspension cable extending at a predetermined length from both ends of the badminton net. In addition, the net hanging support cable is hooked on a hook 25 or the like fixed to a slide collar 24 slidable in the vertical direction of the net support column 21 and fixed at a desired height with a wing bolt 23 so as to be locked and fixed. I have to.

[0003]

However, according to the above-described conventional net support column, (a) the painting of the net support column is easily peeled off by the sliding operation of the slide collar, and (b) the butterfly bolt is connected to the slide collar. The nuts are welded but thin, so the screws are easily crushed, (c) the wing bolts are easily lost, (d) the ends of the net suspension ties are connected to the hooks, and the slide collar is slid down to It is necessary to tension the suspension cable, in which case the slide collar is loaded with the full load of the net and the net suspension cable, so the slide collar is pulled down and tightened with the wing bolt to obtain the desired tension. Is not easy, and (e)
When the slide collar is fixed by tightening the wing bolt to the net support post, if the net is stretched with strong tension, there is a problem that the slide collar jumps up by the recoil when the wing bolt is loosened.

Accordingly, the present invention provides a net supporting column provided with a net suspension anchoring moor which can solve the above-mentioned disadvantages.

[0005]

According to the present invention, there is provided a net support column comprising a hook having a guide groove for a net suspension support rope at a head end thereof, a hook on one side of the rod, and a rope clamped below the hook. Each of the metal fittings is fixed, and a hook is movably inserted through a rope having one end connected to the hook, and the hook is hooked on an annular portion formed at an end of the net suspension cable, and the other end of the rope is hooked. The present invention is characterized in that it has a mooring device for a net hanging support cable which tightens the end portion downward and pushes it into the valley-shaped opening groove of the rope holding metal fitting so as to be clamped.

Accordingly, all the inconveniences of (a) to (e) above are solved, and the function of the moving pulley is achieved by hooking the hook on the annular portion and pulling down the rope, thereby pulling half of the conventional pulley. We can do net extension work with power.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a net support column 1 has an upper cap 2 having a guide groove 3 at the upper end of a tubular rod having a predetermined height. The net suspension cable is slidably supported. An upper hook 4 is planted on the side surface of the net support column 1 at a lower portion separated from the upper cap 2 by a predetermined distance, and a rope clamp 5 is fixed below the hook 4, and a portion immediately below the hook 4. An L-shaped hook 19 and a lower hook 6 are further fixed below the hook. The hook 19 is connected to the net support post 1 to the rope 7
And has a space approximately the same height as One end of a rope 7 is connected to the hook 4 and connected thereto, and a hook 8 such as an eggplant ring is movably inserted into the rope 7, and the other end of the rope 7 is folded back and hangs downward to be attached to the end. A knot 20 for retaining the hook 8 is formed, and the rope 7 can be press-fitted and fixed to the rope clamp 5. A rubber lower cap 9 is mounted on the lower end of the net support column 1.

The upper and lower hooks 4 and 6 are arcuate, respectively. The upper hook 4 is in a transverse direction orthogonal to the axial direction of the net support column 1, and the lower hook 6 is in the axial direction of the net support column 1. , Each is fixed. As shown in FIG. 2, the rope holding member 5 is a groove-shaped member having a projection 10 on which the rope 7 is slidably contacted. Chevron 11
Are formed, and the tapered mountain-shaped projection 1 of the valley-shaped groove is formed.
This is a well-known clamp cleat (made in the UK) that holds the rope 7 by frictional force by pressing and holding the rope 7 between the ropes 1 and 11. The clamp cleat can be fixed to the side surface of the net support column 1 by inserting screws or the like into through holes 12 formed in the groove bottom near the upper and lower ends. However, if there is a locking tool that can replace the clamp cleat, the locking tool may be used instead.

Next, when the net is stretched, as shown in FIG. 3, one end of a net suspension support cable 16 extending from both ends of the net 15 is appropriately connected to one net support pillar (not shown), and the other is shown. As shown in FIG. 4, the upper cap 2 of the other net support column 1 is fitted into the guide groove 3 (see FIG. 4B). An annular portion 17 is connected to the end of the net suspension cable 16 (18 in FIG. 4A) (see FIG. 4A). The hook 8 is hooked on the annular portion 17 (FIG. 4).
(See FIG. 4 (B)), the rope 7 is pulled downward with the other end thereof engaged with the hook 19 (as indicated by the arrow a in FIG. 4 (C)). Pressing (indicated by arrow a in FIG. 4C). At this time, rope 7
Since the hook 19 has a height corresponding to the thickness of the rope 7 from the net support column 1, the hook 19 is guided without detaching from the rope holding metal fitting 5. Alternatively, as shown by an imaginary line in FIG. 2 (A), the rope 7 is turned in the direction of the arrow while the rope 7 is pulled and tensioned in the crossing direction with the projection 10 as a fulcrum, and the taper of the rope clamp 5 is tapered. It may be pressed against the chevron projections 11, 11.

That is, the work of stretching the net can be easily performed even by a woman. As shown in FIG. 5, after the hook 8 is hooked on the annular portion 17, the other end of the rope 7 is connected as shown in FIG. Since the hook 8 can slide on the rope 7 by being pulled downward, the hook 8 acts as a moving pulley, and only applies half of the load applied to the net suspension rope 16 to the rope 7. I have 15 tensions. In addition, after the rope 7 is clamped to the rope clamp 5, the end of the rope 7 may be locked to the lower hook 6 in consideration of the possibility that the clamp is released due to an external factor.

When the net 15 is to be removed, if the rope 7 is engaged with the hook 19 and the lower hook 6, the rope 7 is removed, and as shown by an arrow c in FIGS. When the rope 7 is pulled out, the rope 7 is easily detached from the tapered mountain-shaped projections 11 of the rope-holding metal fitting 5, and then the hook 8 may be removed from the annular portion 17 of the net suspension cable 16 thereafter.

[0012]

According to the present invention described above, since the hook is inserted into the rope having one end connected to the hook of the net support column, the rope is folded back and the other end is pulled down to thereby lower the net. The suspension cable can be tensioned, and moreover, the pulling force of the hooking device acting as a moving pulley is reduced by half, so that the net tensioning work becomes extremely simple and easy. In addition, the detachment of the rope requires only a simple operation of pressing or pulling off the rope clamp, and the rope is held without being detached in the pressed state, so that it is convenient without complicated work. Have.
