[Conventional technology]

As shown in Japanese Utility Model Publication No. 57-8050, a flag pole is attached to a flag rope that is fed out through an opening at the upper end from a flag rope winding device installed below the hollow pole body. be.

Although the details of the winding device are not described in this Japanese Utility Model Publication No. 57-8050, the flag rope winding device is one in which the ends of the flag rope are sequentially wound around a shaft that is rotated by a handle or the like. It is.

[The problem that the idea attempts to solve]

In the above-mentioned winding device, the amount of the flag rope to be let out and the amount to be taken up varies depending on the height of the flag to be hoisted, the size of the boxes themselves, the number of boxes, etc., and as a result, the shaft stop position for the unwinding and winding also varies. It differs each time, and fine adjustment is extremely troublesome.

In addition, the tip of the flag rope let out through the opening at the upper end of the hollow pole body is engaged with the hollow pole body by a flag connecting ring.
In the publication, the upper end of the flag is connected to the flag connecting ring, and when the flag is blown by strong winds, the flag rope loosens and the flag connecting ring is pushed up along the pole body, creating an unstable condition.

To prevent this, it is necessary to secure a position where the flag rope hardly extends out from the opening at the upper end of the hollow pole body, and the flag connecting ring must be placed as close as possible to the crown body at the upper end of the hollow pole body.

In addition, the flag connecting ring is connected vertically through the connecting rod.
Since a plurality of flag connecting rings are slid along the pole main body and are spaced apart from each other, they tend to get caught, and the flag rope may not be able to be paid out smoothly.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
The flag rope winding device not only winds the rope easily and smoothly, but also stops the rope in the same way, and requires special operations to wind and stop the rope. The end of the flag rope can be moved smoothly when it is unrolled from the flag pole.
Moreover, it is an object of the present invention to provide a flag hoisting device capable of hoisting a flag in a stable state.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a flag rope winding shaft installed inside the flag pole with its end facing a through hole provided in the wall of the flag pole main body, and a circle provided on the flag rope winding shaft. Approximately mortar-shaped recesses are provided on the board at appropriate intervals on a concentric circumference, and locking protrusions are slid into and out of the recesses, and the flag rope winding shaft is inserted from the outside of the flag pole through the through holes. A retractable handle is provided on the flag pole to form a flag rope winding device, and a disc-shaped hollow top with a rope guide is rotatably attached to the upper opening of the flag pole body, and the bottom surface of the hollow top is A cylindrical body with an opening at its tip is protruded from an appropriate location of the flag pole, one end is fixed to the flag rope winding shaft, and the other end passes through the hollow top of the flag pole and extends outward through the opening. A weight is provided at the end of the flag rope, and a ring body that is slidably fitted to the pole body is connected to the annular part at the bottom of the weight. A cylindrical body having an inward protruding edge that can be inserted into the cylindrical body of the hollow top part is passed through the flag rope, and a plurality of holes are bored in vertical rows with a width that allows the flag rope to be inserted into the cylindrical body. The gist of the flag is to form a fixture that connects the upper corners of the flag by inserting the elongated plates into the holes in a sequential manner and inserting the elongated plates into the cylindrical body from below.

[Effect]

According to the present invention, in the flag rope winding device, approximately cone-shaped recesses are provided on the concentric circumference at appropriate intervals in a disc provided on the winding shaft, and the locking protrusions are slid into the recesses. Since the rope is let out, it is possible to not only wind up the rope at the desired position but also stop the unwinding in the same operation, and to stop and release the rope, no special operations are required just by starting and stopping the rotation of the handle. It is easy to carry out because it does not require any additional work.Furthermore, since the flag rope is always held in tension by a weight, the flag rope is tightly wound around the winding shaft without becoming loose or tangled, making the winding and unwinding operation smooth. can be done.

In addition, the handle can be attached to and detached from the flag pole, so
By storing this separately when not in use, it is possible to prevent it from being tampered with and it also looks good.

On the other hand, when the flag is being hoisted, the inward flange of the cylinder of the mount that connects the upper corner of the flag is inserted into the cylinder of the hollow top of the flag pole body, and the brim is attached to the tip of the cylinder on the hollow top side. Since it touches the edge of the opening, it can be firmly fixed, and even when the flag is blown by strong winds, the top corner of the flag does not move, so it remains stable.

Furthermore, the attachment position of the flag to the flag rope can be easily changed by changing the position where the rope is sewn through the elongated plate.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of the flag hoisting device of the present invention, FIG. 2 is a longitudinal sectional side view of the winding device portion of the present invention, and FIG. 3 is a cross-sectional plan view.

Regarding the winding device, a flag rope winding shaft 2 is formed by fitting a cylinder 3b into the outer peripheral surface of the shaft 3a and fixing it with screws 4. A square hole 1 for connecting the handle end is provided at one end of the shaft 3a. form.

A disk 5 is fitted to one end of the cylindrical body 3b of the winding shaft 2, and a gear 10 is attached to the other end. A plurality of approximately mortar-shaped recesses 6 are formed on one side of the disk 5 at appropriate intervals so as to be lined up on the concentric circumference of the disk 5.

The shaft 3a of the winding shaft 2 is connected to the bearings 11a, 1
It is fixed to the case 13 via 1b with the axial direction horizontal.

A locking part 8 consisting of a rod 7a having a chevron-shaped locking protrusion 7 at its tip and a spring 9 that presses the rod forward is housed in a cylindrical case 12, and the protrusion 7 engages with the recess 6. Then, position the cylindrical case 12 on the case 13.

Note that, in order to smoothly engage and disengage the projection 7 with the substantially cone-shaped recess 6, it is preferable that the projection 7 is made of synthetic resin such as nylon, for example.

As another embodiment, in order to make engagement and disengagement smoother, as shown in FIG. A locking portion 8' is constituted by a spring 39 that presses the device forward, and is housed in the cylindrical case 12.

On the other hand, a synthetic resin layer 42 such as nylon is buried in a recess 41 formed in the disk 40, and the synthetic resin layer 42 is
A recess 43 is provided in the.

It is good when this synthetic resin layer 42 is thick, but when it is thin, a hole 44 is provided in the main body of the disk 40 so as to communicate with the recess 43 of the layer 42.

In this way, the metal ball 37 comes into line contact with the recess 43 and acts as a bearing, so that it can be slid into and out of the recess 43 smoothly without any resistance.

Further, above the winding shaft 2, a guide roll 15 for winding the rope is mounted on a bearing 17 in parallel with the winding shaft 2.
It is fixed to the case 13 via a and 17b.

As shown in the developed view of FIG. 4, this guide roll 15 has peaks 14b having acute angles at both ends and having a length approximately equal to half the circumference of the guide roll 15, which are arranged in a staggered manner so that the acute angles overlap each other. Arranged around the shaft.

In this way, the mountain portion 1 is placed on the guide roll 15.
A spiral groove 14a-1 surrounded by 4b and a spiral groove 14a-2 in the opposite direction are formed, and both grooves 14
a-1 and 14a-2 intersect between the peaks 14b.

A gear 16 is attached to the end of this guide roll 15 and meshed with the gear 10.

A case 13 is installed below the aluminum hollow pole main body 18, and the square hole 1 of the shaft 3a of the winding shaft 2 is
facing the through hole 19 formed in the pole body 18.

Note that 20 in the figure indicates an inspection window hole formed in the pole body 18.

As shown in FIG. 5, the upper part of the pole body 18 is
A disk-shaped hollow top part 23, also made of aluminum, was coaxially and rotatably attached to the upper end opening via a bearing 22. In the figure, 23a indicates a communication hole provided at the center of the lower surface of the top portion 23.

A cylindrical body 25 is protruded from an appropriate location on the lower surface of the top portion 23, and its tip is an opening 25a. Rope guides 24, 24' are disposed within the top portion 23 above the communication hole 23a and the opening 25a.

In the figure, reference numeral 34 denotes a fixture for connecting the upper corner of the flag, and the fixture 34 integrally forms the flanges 30a and 30b with a gap between them, and has an opening in the cylindrical body 25 at the end of the upper part 28b of the flanges 30a. It is composed of a cylinder 28 having an inward protruding edge 28a that can be inserted into the cylinder 25a, and an elongated plate 27 having a plurality of holes 26 formed in vertical rows with a width that can be inserted into the cylinder 28. Further, a ring body 32 that is slidably fitted onto the pole body 18 is connected to one annular portion 31b of the weight 31.

Insert the middle of the rope 29 pulled out from the winding shaft 2 of the flag rope winding device installed below the pole body 18 into the spiral groove 14a-1 or 14a-2 of the guide roll 15, and It passes from the upper end into the top part 23 through the communication hole 23a, and then passes through the opening 2 through the rope guides 24, 24'.
Pay out from 5a.

In this way, the rope 29 suspended from the upper end of the pole body 18 so as to be freely raised and lowered is passed through the cylindrical body 28, and then threaded through the holes 26 formed in the elongated plate 27 in sequence, and flanges 35a and 35b are attached to the upper and lower ends. After inserting it into the formed cylindrical body 35, the end is attached to the weight 3.
1 to the other annular portion 31a.

The elongated plate 27 is firmly fixed by sewing the rope 29 through the hole 26, and if inserted into the cylindrical body 28 in this state, the cylindrical body 28 will be attached to the rope 29 via the elongated plate 27. It will be a long time.

Next, how to use it will be explained based on the first embodiment.The end of the rotating handle 21 is inserted into the square hole 1 through the through hole 19 formed in the pole body 18, and the end of the rotating handle 21 is rotated by hand. The shaft 2 is reversed and the flag rope 29 is let out.

According to the rotation of the shaft 3a, the disk 5 also rotates via the cylinder 3b. At this time, since the locking protrusion 7 is formed in a chevron shape, it is easily slid out when the mortar-shaped recess 6 moves, and when the next recess 6 comes, it is retracted by the elasticity of the spring 9. As long as the disk 5 continues to rotate, this movement of engagement and disengagement is repeated.

Further, the rotation of the gear 10 is transmitted to the gear 16, and the guide roll 15 also rotates.

The flag rope 29 wound around the shaft 2 is connected to the cross spiral groove 14a-1 or 14a of the guide roll 15.
-2 and is guided by this from one end of the guide roll 15 to the groove 14a-1 on the outward path and the groove 14a-1 on the return path.
It is sequentially unwound from the winding shaft 2 while reciprocating from side to side through a-2. The tip of the rope 29 hangs down from the cylindrical body 25 of the top part 23 due to the weight of the weight 31 and descends along the pole body 18.

When the rope 29 is let out to a length that allows the flag 33 to be attached, the rotation of the handle 21 is stopped.
The rotation of the winding shaft 2 and the disc 5 is stopped, and the protrusion 7 is recessed into an appropriate recess 6.

In this state, unless a particularly strong rotational force is applied by the handle 21, the take-up shaft 2 will not move, and as a result, the rope 29 will not be unwound any further.

In order to attach the flag 33 to the rope 29, the rope 2 between the elongated plate 27 and the annular portion 31a of the weight 33 is attached.
So that the length of the flag 9 is almost equal to the vertical width of the flag 33,
Adjust the mounting position of the elongated plate 27.

The flag 33 has tied strings 33 at the top and bottom corners and in the middle.
a, 33b, and 33c are provided, the string 33a at the upper corner is connected to the body of the cylinder 28, the string 33b at the lower corner is connected to the annular part 31a of the weight 31, and the string 33c inside is connected to the body of the cylinder 3.
Tie it to the body of 5. At this time, the tsuba 30b, 30
There is no fear that the strings 33a and 33c will fall off due to the strings a and 35b.

Next, when the handle 21 is turned to rotate the winding shaft 2 in the forward direction, the disc 5 also rotates against the elastic locking force of the protrusion 7, and the protrusion 7 slips out of the recess 6 and engages with the recess 6 again. Repeat the engagement and disengagement.

In addition, the guide roll 1 is
5 also rotates, and the intersecting spiral groove 14a-1 or 14
The rope 29 wrapped around a-2 is again guided by it and repeats reciprocating motion from one end of the guide roll 15 through the groove 14a-1 on the outward path and through the groove 14a-2 on the return path. , the rope 29 is the winding shaft 2
It is wound uniformly over the entire length from end to end between the disc 5 of the cylindrical body 3b and the gear 10.

Note that by observing the internal winding device through the inspection window 20, it is possible to know whether winding is being performed smoothly.

In this way, the flag 33 rises via the rope 29, but the tip of the rope 29 to which the flag 33 is attached is constantly pulled downward by the weight of the weight 31.
Further, since the ring body 32 runs along the pole main body 18, it rises smoothly without getting tangled.

When the inward projecting edge 28a at the upper end of the cylinder 28 is inserted into the cylinder 25 at the top 23 and the collar 30a comes into contact with the end of the opening 25a, the cylinder 28 is stopped from rising any further, and the flag 33 is stopped. The upper corner engages with the top 23 via the cylinder 28.

If the rotation of the handle 21 is stopped at this point, the protrusion 7 is re-inserted into the recess 6 and the movement of the winding shaft 2 is stopped.

The lower corner of the flag 33 hoisted at the top of the pole body 18 in this way is locked to the pole body 18 via the ring body 32 and the weight 31 and continues to be pulled downward, so even if it receives wind from below. It doesn't get stuck or tangled. Furthermore, the top 2
3 and the ring body 32 rotate simultaneously with respect to the pole body 18, it is possible to prevent the flag 33 from wrapping around the pole body 18.

To lower the flag 33 from the pole body 18, the reverse operation is performed.

[Effect of idea]

As described above, in the flag hoisting device of the present invention, concave concave portions are provided on a concentric circumference at appropriate intervals on a disc provided on a winding shaft, and a locking protrusion is slid into the concave portion and slid out. As a result, it is possible to not only wind up the rope at a desired position but also to stop its unwinding in the same operation, and to stop and release the rope, no special operation is required just by starting and stopping the rotation of the handle. It is easy to carry out because it does not require any winding. Furthermore, since the flag rope is always held in tension by a weight, the flag rope is tightly wound around the winding shaft without becoming loose or tangled, making the winding and unwinding operation smooth. It can be done.

In addition, the handle can be attached to and detached from the flag pole, so
By storing this separately when not in use, it is possible to prevent it from being tampered with, and it also provides a good appearance.

In addition, when the flag is being hoisted, the inward protrusion of the cylindrical body of the fixture that connects the upper corner of the flag is inserted into the cylindrical body of the hollow top of the flag pole body, and the brim is inserted into the cylindrical body of the hollow top side of the flag pole. Since it touches the opening end of the tip of the body, it can be firmly fixed, and even when the flag is blown by strong winds, the upper corner of the flag does not move, so it remains stable.

In addition, changing the attachment position of the flag to the flag rope,
This can be easily done by changing the position where the rope is sewn through the long and thin plate.
