Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hanging metal fitting for a ball-proof net which is stretched around the periphery of a golf practice field, a school ground, or the like.

[Conventional technology]

For example, a ball-proof net is stretched around a spherical gland to prevent dangers caused by flying balls.

That is, concrete stanchions for supporting ball-proof nets are erected at predetermined intervals around the circumference of the gland, and a strut holding member is used to hold the struts above the concrete struts while holding the struts. And a bracket is connected to the strut holding member, and a guide wire is stretched from the bracket to the vicinity of the lower end of the strut while the upper edge of the ball-proof net is pulled up to An edge is connected to the bracket, and a key point of the ball-proof net is connected to the guide wire, so that
A ball-proof net is stretched around the ground.

[Problems to be Solved by the Invention] However, the above-mentioned means for stretching the ball-proof net has the following problems.

That is, conventionally, a wire is connected to the upper edge of the ball-proof net to pull up the ball-proof net, and the upper edge of the ball-proof net is connected to the bracket. In addition to the new construction of the ball-proof net, the workability of maintenance by lowering and lowering the net was also poor.

Also, since the strut holding member is a considerable heavy object,
It is considerably difficult to support this and attach it to the strut with bolts and nuts, and it is extremely difficult to attach it at a fixed position for all of the strut, and the bolts and nuts may become loose. The mounting position of the strut holding member may be displaced due to a strong external force generated by stretching the ball-proof net or the guide wire, and the upper edge position of the ball-proof net is different for each strut. Therefore, the upper edge of the ball-proof net becomes wavy, and it is difficult to keep the upper edge position constant, and the net portion around the lower upper edge position swells due to wind pressure, and The appearance of the laid net was bad.

Then, this invention aims at providing the hanging metal fitting of a ball-proof net which does not have the said conventional fault.

[Means for Solving the Problems]

In order to achieve the above object, the hanging fitting of the ball-prevention net according to the present invention is such that the bracket is connected to the strut holding member which is attached while holding the upper side of the concrete strut by the bolt and the nut. , A wire for raising and lowering the guide wire connected to a ring connected to the ball-proof net, one end side of which is connected to the upper side of the ball-proof net and the other end of which is connected to a wire lifter near the ground Is provided with a connecting portion of a pulley for winding, and further, a fall prevention tool that locks at the upper end of the pillar to control the fall of the pillar holding member is connected to the pillar holding member. is there.

[Action]

According to the above-mentioned characteristic configuration, the fall prevention tool connected to the supporting column holding member is locked so as to be deposited at the upper end of the supporting column, and the supporting column holding member is supported by the supporting column, thereby supporting the supporting column holding member. Is installed at the same height position on each column, and
Even if the bolts and nuts are loosened or a strong external force is applied due to the tension of the ball-prevention net or the guide wire, the mounting position of the strut holding member is fixed as a predetermined position by the function of the fall prevention tool.

Further, the ball lifting net wound around the pulley can be wound tightly by the wire lifting machine, or the ball lifting net can be strongly stretched, or the ball lifting wire can be unwound to lower and lower the ball blocking net. ,And,
The work is safely done on the ground.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 3 is a column that is erected at a predetermined interval around the circumference of the gland, and the hanging metal fitting 2 is attached to the upper side of each column 3 via a bolt a and a nut b.

4 is a wire lifter with a built-in ratchet mechanism, where three adjacent columns 3 are grouped together and the central column 3
It is attached to the vicinity of the ground surface via a belt metal fitting 5. Then, three pulleys 8 are provided on the hanging metal fittings 2 of the pillar 3 equipped with the wire elevator 4, and one pulley 8 is attached to each of the hanging metal fittings 2 of the pillars 3 on both sides thereof. There is.

Reference numeral 6 denotes a guide wire, which is stretched from the hanging metal fitting 2 over the ground near the lower end of the column, and is connected to a ring 7 provided at a key part of the ball-proof net 1.

In the above-mentioned structure, the three wire raising / lowering wires 9 are connected to the wire lifter 4 and the wires 9 are wound around the three pulleys 8 and two wires 9 therein are supported on both sides. 3 is wound around the pulley 8 and one end side of the three wires 9 is connected to the upper edge side of the ball-proof net 1, and thus a portion corresponding to the three adjacent columns 3 Ball-proof net 1 of one wire elevator 4
Can be raised and lowered all at once, and the ball-proof net 1 can be strongly stretched by the wire lifter 4, and important points of the ball-proof net 1 are connected to the guide wire 6 via the ring 7. Therefore, it is possible to prevent the ball-proof net 1 from being greatly expanded by the wind pressure.

Here, a specific structure of the hanging fitting 2 will be described. As shown in FIG. 6 to FIG. 11, the hanging metal member 2 includes two strut holding members 10 in which flanges 10b are continuously provided on both sides of a semi-cylindrical member 10a, and one of the strut holding members. Holding member
A bracket 11 that is connected to the semi-cylindrical member 10a of 10 and a half that is connected to the upper part of the one pillar holding member 10 and is locked to the upper end of the pillar to prevent the pillar holding member 10 from falling off. It consists of a circular drop prevention tool 12.

The bracket 11, the vertical plate portion 11a is welded to the outer surface of the semi-cylindrical member 10a, the horizontal plate portion 11b is welded over the upper edge of the vertical plate portion 11a and the upper surface of the fall prevention tool 12, and The lower surface of the horizontal plate 11b and the vertical plate 11a

It may be configured with a belt fitting.

[Effect of device]

As described above, according to the present invention, since the strut holding member is provided with the fall prevention tool, the strut holding member can be easily attached to the strut without supporting the strut holding member.

In addition, it is easy to position the strut holding member at the same height position for each strut, and even if the bolts and nuts are loosened, or the guide wire or ball-proof net is stretched. Even if a strong external force is applied, the column holding member will not be displaced.

Thus, in addition to the ball-proof net being connected to the guide wire via the ring, the strut holding member is not displaced and the strut holding member can be positioned at the same height position. Therefore, the ball-proof net can be laid out nicely and neatly without causing a large bulge of the net due to wind pressure and waviness of the upper edge of the net.

Then, a pulley is attached to a bracket continuously provided to the strut holding member, and a wire for raising and lowering the net, one end of which is connected to the ball-proof net and the other end of which is connected to the wire lifter, is wound around the bracket, The work of tensioning and lowering the ball net can be carried out safely on the ground, and the workability of new installation and maintenance of the ball net can be improved.
