Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a support device for a carp streamer column, which comprises a plurality of metal tubes or synthetic resin tubes having different diameters.

[Prior Art] Conventionally, a support made of an expandable tube used for carp streamers, etc.
Insert the lowermost tube of the shrunk tube so as to cover the pile driven into the ground, and after inserting this, combine the bolt hole drilled in the lowest tube and the bolt hole provided in the pile The bolts were inserted in and the nuts were tightened and fixed to stand upright.

[Problems to be Solved by the Invention] In the conventional support device for a pillar, the lowest tube of the pillar is inserted into the exposed portion of the pile driven into the ground, and the lowest tube inserted into this pile is drilled. The bolt holes and the bolt holes provided in the pile, together with the bolts inserted and fixed in the bolt holes, were very troublesome, troublesome, and difficult and heavy labor.

[Means for Solving Problems] The present invention has been made in view of the above circumstances in order to solve these problems, and in a stretchable strut, the base of the lowest single pipe of this strut is formed. Is rotatably supported by a bolt on a holder fixed to the exposed lower side of the pile driven into the ground, and at the upper side of the pile, the bottom single pipe is sandwiched and the end on the opening side is bolted. It is fixed to the pile with, and the tilting degree is adjusted by pressing the pillar with the adjusting bolt and the protective plate screwed on the bottom of the holder, and it is easy to install the pillar. It is provided for the purpose.

[Embodiment] Next, an embodiment of a support device for a carp streamer strut according to the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a strut, which is configured by expanding and contracting a plurality of single tubular bodies 1a, 1b, ... Made of metal or synthetic resin having different diameters. The lowest single tubular body 1a of the strut 1 has a large diameter. As the pipes, the small diameter pipes 1b are sequentially formed.

Reference numeral 16 is a mounting pile when the strut 1 that can be expanded and contracted is set on the ground W, and the pile 16 is the ground W.
The lower part is driven in, U-shaped holders 17 and 18 are provided at the upper and lower positions exposed from the ground W, and the column 1 is mounted by this holder.

The holder 17 on the lower side of one side is fixed to the pile 16 with the bottom surface of one end of the U-shaped portion by bolts 19, and the lower side of the lowest single tubular body 1a of the strut 1 is fitted on the open side of the other side of the holder. It is provided by being rotatably supported by a bolt 20 and a nut 21 so as to be rotatable.

Further, a holder 18 on the upper side of the pile 16 is inserted from the open side so as to sandwich the lowermost single tubular body 1a opposite to the holder 17, and is further provided at the tip of an adjusting screw rod 22 screwed to the bottom surface U-shaped portion. The protective plate 23 is applied to the lowermost single tube body 1a, and the lower end single tube 1a pivotally supported on the opening side of the holder 17 is rotated around the base end of the holder 17 and the end portion of the holder 19 is opened. After inserting the pile 16 into the pile 16 and holding it, the bolt 24 and the nut 25 are tightened and fixed.
A spacer 26 is interposed between the lowermost single pipe 6 and the lowermost single pipe 1 and the tightening prop 1 is erected while adjusting the tilt of the prop 1 in the direction of the pile 16 through the protective plate 23 with the adjusting screw rod 22. To do.

The single pipe body of the support column 1 has a spacer 2 adapted to prevent rattling of a small-diameter pipe side, that is, an inner pipe inserted into the large-diameter pipe side, on the upper end side of each large-diameter pipe side, and an inner pipe. Spacers 3 are similarly interposed on the outer circumference of the lower end, and the large-diameter pipe and the small-diameter pipe are slidably fitted to each other.

On the upper side of each large-diameter pipe, a holder 5 pivotally supporting a pulley 4 is fixed by an appropriate means such as welding or a rivet, and
The large-diameter pipe corresponding to the pulley 4 is provided with a guide hole 7 through which a cord member 6 such as a wire hanging on the pulley 4 is inserted.
Is installed. Further, an insertion hole 9 for attaching the end portion of the cord member 6 is formed in the upper portion of the lower end spacer 3 provided in the small-diameter pipe, that is, the inner pipe, and the end portion of the cord member 6 inserted in this is attached to a crimp sleeve or the like. It is attached by appropriate means. Further, in each of the single tubular bodies 1a, 1b, ..., The lower end of the single tubular body slidably fitted inside the tubular body is contracted to the upper position of the insertion hole 9 where the end portion of the string member 6 is attached at the lower end side. Stopper 10 to catch when a little later
Is provided.

The other end of the string member 6 is attached to the holder 5 of the pulley 4 attached to the upper portion of the next large diameter pipe through the pulley 4.

The string member 6 is cut into a certain size, and the length of the single tubular body is adjusted at an arbitrary position within a range where the string member 6 has a play.

The lowermost end of the string member 6 is connected to a winch 11 which is attached to an easily operated portion of the lowest single tube body 1a by an appropriate means.

The winch 11 comprises a holder 11a, a winding shaft 11b provided with a detachable handle 11c at one end, and a stopper 13 for stopping the winding shaft 11b. The stopper 13 is a rod provided at the end of the winding shaft 11b. The holder 12 is inserted into and removed from the holder 11a so as to be disengaged. That is, when it is desired to stop the rotation of the winding shaft 11b, the stopper 13 is moved to receive the rod 12, or the stopper 13 is moved from the locking position of the rod 12 to release and lock.

As the locking means, as shown in FIGS. 1 and 2, a ratchet gear 14 is provided, and various kinds of locking means such as locking with a pawl 15 facing the ratchet gear 14 can be used.

[Operation] With the above-described structure, the present invention is the lowest in the state where the pillars 1 that expand and contract with a plurality of single pipes are respectively inserted into the piles 16 of the pile 16 that is driven into the ground and exposed from the ground, and are reduced. Single tube 1
Fix the open side of the holder 17 that axially supports the base side of a,
The support 1 is rotated around the pivotal support of the holder 17 to vertically install the support 1 along the pile 16.
The tip end side of the upper holder 18 is inserted into the pile 16 to fix the holder 18, and the spacer 26 is interposed between the support 1 and the pile 16 so as to stand upright via the adjusting screw rod 22 and the protective plate 13. Tighten and install while watching.

When the support column 1 is installed, the winch 11 provided on the lowermost single tubular body 1a is operated to extend the support column 1.

After use, the support 1 is shrunk to the storage state, and the lowermost single pipe of the shrunk support is pulled out from the pile 16 by removing the upper holder 18 fixed to the pile 16 by holders 17 and 18.
While rotating the lower holder 17 that pivotally supports the lowest single tube around the pivot point of the lower holder 17, the lowest single tube that accommodates the single tube is laid down sideways, and the axial support portion of the holder 17 is released for disassembly and storage. .

[Effect] As described above, according to the present invention, when a plurality of single pipes having different diameters are sequentially slidably fitted to each other to be expanded and contracted, the pillar is attached to the pile driven into the ground to stand upright. The bottom end of the fixed lower strut is pivotally supported at the bottom end of the tube, and the strut is contracted about this to raise it.The upper holder is fixed to the pile, and the tilt angle is adjusted with the adjusting bolt. It can be installed by one person with good efficiency.
