Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mooring rope for keeping a floating body such as a water motorcycle or a boat floating on a coast or shallow water of a riverbank so as not to drift. Further, when the mooring rope is detached from the floating body, it is a mark (marker) showing a place where the floating body is moored (for example, a place where the floating body returns after going offshore).
Also has the role of.

[0002]

2. Description of the Related Art Conventionally, as this type of mooring rope (mooring device), (a) an ordinary non-stretchable rope, hooks provided at both ends of the rope, and attached so as not to move to a proper position of the rope There is known a mooring device including a float (float) and a bag as an anchor substitute that can be attached to a hook on the side opposite to the float, and the bag holds sand and stones. (B) An ordinary non-stretchable rope, hooks provided at both ends of the rope, and a float (float) attached so that the rope does not move to a proper position.
And mooring devices comprising an anchor attached to the hook opposite the float.

[0003]

However, in both the above-mentioned conventional examples (a) and (b), (a) the length of the rope is generally about 3 m to 8 m (not limited to this value). Since it is an ordinary rope that does not expand and contract, it has the drawback that the rope is entwined (wound) in a spiral shape under the influence of water flow and wind.

(B) Further, as described above, since the rope is wound in a spiral shape, when the floating body erroneously passes through the spirally wound rope when mooring the floating body, the floating body is floated. There is a drawback that the pump case and the impeller attached to the pump case and the impeller are damaged when the rope is entangled.

(C) Furthermore, the above conventional example (a),
In (b), since an ordinary rope that does not expand and contract is used, it is bulky when it is stored when not in use, and when used as a tow rope, it has the drawback of suddenly starting to the towed floating body. .

(D) In the floats (floats) of the conventional examples (a) and (b), it is troublesome to mount them at a predetermined position, and it is troublesome to change the mounting position.

(E) The ropes of the conventional examples (a) and (b) are cumbersome and in use because the lengths of the ropes are adjusted by connecting the ropes at appropriate places. There was a drawback in that the knot unraveled.

The present invention has been devised in order to eliminate the drawbacks of the above-mentioned conventional examples (a) and (b), and eliminates the entanglement of the rope to prevent the pump case and the impeller from being damaged. The mooring makes it possible to eliminate the bulkiness of the rope when it is stored, to eliminate sudden starts when it is used as a tow rope, to easily change the mounting position of the float, and to easily adjust the length of the rope. The purpose is to provide a rope for use.

[0009]

In order to achieve the above object, the mooring rope of the present invention has a rope at least a part of which can be extended and retracted, hooks provided at both ends of the rope, and the rope at appropriate positions. And a provided float.

Here, it is optimal that the entire length of the rope is stretchable, but a part of the rope may be stretchable, for example, only near both ends or only near the central portion. Also,
The material of the rope does not matter, but it is a material that is strong against tensile strength and does not rust, for example, nylon rope woven with specially processed rubber, or other plastic yarn woven,
A coil spring, which can be expanded and contracted, or the like may be appropriately selected.

The hook may be a commercially available one or any other structure as long as it can be engaged with an anchor or a hooking portion of a floating body (watercraft, etc.).

The float may be made of any material and may have any shape as long as it floats on water, but a float having a large buoyancy is preferable. Further, it is preferable that the float is slidably provided on the rope. This allows the mounting position of the float to be adjusted.

In the vicinity of the connection between the hook and the rope,
It is better to provide a grip that covers both ends of the rope. By providing this grip, it is easy to work when the hook is hooked on or off the anchor or the floating body above the water. In particular, even if the rope covered with the grip is elastic and elastic, the grip allows the hanging operation to be performed without any hindrance.

It is preferable to have an adjusting band for adjusting the length of the rope. By using this adjusting band, the length of the rope can be adjusted to a desired length.

[0015]

First Embodiment FIG. 1 shows a first embodiment of the present invention.
This will be described below with reference to FIG. 7. FIG. 1 shows the entire length of the rope that can be expanded and contracted, and in this figure, the rope is shown in a contracted state. In FIG. 1, the mooring rope 1 is
A rope 10 whose total length is extendable and contractable, a hook 20 connected to both ends of the rope 10, a float 30 inserted into a proper position of the rope 10, and both ends of the rope 10 in the vicinity of a connecting portion between the hook 20 and the rope 10. Rope 1 inserted in the part
And a grip 40 that covers both end portions of 0.

The rope 10 can be arbitrarily selected as long as it is a material having high tensile strength and excellent durability without rusting, but in the present embodiment, a rope woven with nylon or synthetic resin fiber is used. ing. In this embodiment, the rope 10 is about 2 m in a contracted state and about 6 m in an extended state.
The length of the rope 10 in a contracted state and the length of the rope 10 in an extended state can be appropriately selected.

The hook 20 is a hook portion 50a (see FIGS. 4 and 5) of an anchor 50 installed on the seabed (water bottom) and a hook portion 51a of a floating body 51 such as a watercraft or a boat.
(See FIGS. 5 and 6). In this embodiment, the rope 10 is attached to the engaging portion 21 at the base of the hook 20.
The end portion of the rope 10 is inserted, and the end portion of the rope 10 is bent and inserted into the center side of the rope 10 to connect the hook 20 and the rope 10. The hook 20 is pivotally supported at the open end of the engaging portion 21 at the base portion by a pivot 22, and a spring 24 urged so that the opening 23 of the hook 20 is always closed by a tongue piece 25 is provided on the pivot 22. It's wrapped around.

The hook 20 is not limited to the one shown in the figure and can be arbitrarily selected as long as it can engage with the anchor 50 and the floating body 51 as described above. Also, hook 2
The connection between 0 and both ends of the rope 10 is not limited to the illustrated structure.

In this embodiment, as described above, the tubular float 30 and the tubular grip 40 are fitted into the rope 10 in advance before the hooks 20 are connected to both ends of the rope 10. The float 30 and the grip 40 will be described below.

The float 30 is made of a material such as sponge resin which has a large buoyancy and is highly water resistant and durable.
It is cylindrical and has a cut surface as shown in FIG. The float 30 may be fixed at a fixed position on the rope 10, but is slidable with respect to the rope 10 in this embodiment. By doing so, the mounting position of the float 30 can be adjusted.

The grip 40 is made of a hard synthetic resin, and a stopper 41 is integrally formed on one end side of the diameter position of the tip outer peripheral wall of the grip 40.
The projection 42 formed on the other end side of the grip 40 is fitted into the fitting hole 43 formed on the other end side of the diameter position of the tip outer peripheral wall of the grip 40. By inserting the stopper 41 into the engaging portion 21 at the base of the hook 20 and fitting the protrusion 42 of the stopper 41 into the fitting hole 43 of the grip 40, the grip 40 moves toward the center of the rope 10 ( That is, hook 20
It is positioned so that it does not move in the direction of further separation.

Next, the operation of the first embodiment will be described with reference to FIGS. (1) When the floating body 51 is moored to a shore or a shallow water on the riverbank (see FIG. 4). When mooring the floating body 51 in a shallow water as shown in FIG. 4, the hook 20 on one side of the mooring rope 1 is engaged with the hook portion 51a of the floating body 51, and the hook 20 on the other side is anchored to the anchor 50. It suffices to engage the hooking portion 50a and place the anchor 50 at the bottom of the shallow water on the coast or river bank. Then, although the mooring rope 1 is affected by the direction and strength of the ocean current (water current) and the wind, the mooring rope 1 becomes inclined, straightened, or slightly extended as shown in FIG. Therefore, the rope is not entangled as in the conventional example. The length of the rope 10 can be adjusted by using an adjustment band as described below.

(2) When the mooring rope 1 is detached from the floating body 51 and the mooring rope 1 is used as a mark (mark) (see FIG. 5). In this case, due to the buoyancy of the float 30, at least the portion of the float 30 projects from the water surface (sea surface) 60, as shown in FIG. Therefore, by looking at the float 30, for example, the operator of the floating body 51 floating offshore knows the place (the mooring place) where he / she should return. In this case, since the rope 10 is contracted, the rope is not entangled as in the conventional example. Therefore, when mooring the floating body 51, it is possible to avoid accidentally passing through the rope 10, and it is possible to prevent the rope 10 from being entangled with the pump case or the impeller of the floating body 51, which may damage the pump case or the impeller. Can be prevented.

(3) When the mooring rope 1 is used as a tow rope for the floating body 51 (see FIG. 6). In this case, the hook 20 on one side of the mooring rope 1 is engaged with the hook portion 51a of the floating body 51, and the hook portion 50a of the hook 20 on the other side is hooked on the towing float 61 of a boat such as a water boat. It engages with the portion 61a. Therefore, when the towing floating body 61 is driven to run to pull the floating floating body 51, the rope 10 of the mooring rope can be expanded and contracted as shown in FIG. 7, so that a sudden impact at the time of towing is absorbed. As a result, the floating body 51 is smoothly pulled.

In the cases (1) and (2), the float 30 may be slid on the rope 10 to an appropriate position to adjust the attachment point.

As mentioned above, it is better to provide an adjusting band for adjusting the length of the rope 10 of the mooring rope 1. The specific structure of the adjustment band is not particularly limited, but a loop-shaped adjustment band 70 as shown in FIG. 8 can be used, for example.

A method of using the adjusting band 70 will be described below with reference to FIGS. 9 to 15. First, as shown in FIG. 9, the portion of the rope 10 to be adjusted is folded in two, and the adjustment band 70 is applied to the upper surface of the folded portion of the rope 10 as shown in FIG. Insert in the direction of and pull up as shown in FIG. Then, as shown in FIG. 12, both ends of the adjustment band 70 are pulled up and tightened. Next, the loop portions 70a at both ends of the adjustment band 70 in the above state and the hook portions 50a of the anchor 50 are engaged with the hooks 20 on one end side of the mooring rope 1 (see FIGS. 13, 14, and 15). . Although not shown in FIG. 15, the hook 20 on the opposite side is engaged with the hook portion 51a of the floating body 51, so that the mooring state is maintained as shown in FIG.

The mooring rope 1 adjusted by the adjusting band 70 can be used as a mark as shown in FIG. 5 by freeing the hook 20 on the opposite side as shown in FIG.
Becomes In addition, the hook 20 on the one side is attached to the floating body 51.
Of the hook 2 on the other side while engaging with the hook portion 51a of
When 0 is engaged with the hooking portion 61a of the tow float 61, the mooring rope 1 is used as a tow rope as shown in FIG.

[0029]

Second Embodiment of the Invention FIG. 16 shows a second embodiment of the present invention. The mooring rope 1 according to the second embodiment has a full length which can be expanded and contracted, and FIG. 16 shows a state in which the rope is contracted. The mooring rope 1 of the second embodiment is characterized in that two floats 30 are separately fitted and inserted, and other configurations are similar to those of FIG. Therefore, in FIG. 16, the same reference numerals as those in FIG. 1 are shown, and the operation, usage, and the like are the same, and thus detailed description will be omitted.

In this case, the floats 30, 30 can be fixed at a fixed position in a separated state or a continuous state, but it is preferable that the floats 30, 30 can be slid with respect to the rope 10. By thus sliding the floats 30, 30, there is an advantage that the mounting positions of the floats 30, 30 can be arbitrarily adjusted.

Although two floats 30 are provided in FIG. 16, three or more floats 30 may be provided, though not shown.

[0032]

[Modifications] The rope 10 of the mooring rope 1 is not limited to the one described above, and a long object made of metal, for example, in the form of a coil spring can be used, but it is heavy and bulky. is there.

The mooring rope 1 without the grips 40 at both ends of the rope 10 can also be implemented. In this case, when both ends of the rope 10 are hard, the grip 40 may be omitted, but when both ends are jumbled, it is better to provide the grips 40 and hold the grip 40 and the hook 20 in a horizontal posture.

As a method of attaching the float 30 to the rope 10, the float 30 is formed in a tubular shape and the float 30 is fitted into the rope 10 in each of the above embodiments, but the method is not limited to this. . For example, float 30
As, using a rectangular sheet of an appropriate length, the rectangular sheet may be provided with a belt-shaped fastener on the back surface of the long side on one side, and a belt-shaped fastener may be provided on the surface of the rectangular portion on the other side. Alternatively, the rope 10 may be rolled up at a proper position to join the both belt-shaped fasteners, and the design can be changed appropriately.

[0035]

According to the mooring rope of the first aspect of the present invention, since at least a part of the rope is held in a contracted state at all times by using a telescopic rope, the rope is not entangled in a spiral shape. When the floating body is moored, the rope can be prevented from being entangled with the pump case or the impeller of the floating body, and the pump case and the impeller can be prevented from being damaged.
Moreover, since the rope is contracted, it does not become bulky when storing or carrying. Furthermore, when the mooring rope of the present invention is used as a tow rope, the rope is contracted, so that a sudden shock is absorbed and the towed floating body is smoothly towed without suddenly starting.

Further, since the float is provided at a proper position on the rope, it is possible to save the labor of attaching the float to a predetermined position of the rope as in the conventional example, and it is surely floated when dropped in water. Therefore, as shown in FIG. When the mooring is removed, it serves as a mark of the mooring place, and at the time of mooring as shown in FIG. 4, the floating floating body moored can be confirmed by identifying the float.

According to the mooring rope of the second aspect, since the grips for covering both ends of the rope are provided, it is easy to work when the hook is hooked on or off the anchor or the floating body. In particular, even if the rope covered with the grip is elastic and elastic, the grip allows the hanging operation to be performed without any hindrance.

According to the mooring rope of the third aspect, since the float can slide with respect to the rope, the mounting position of the float can be easily changed.

According to the mooring rope of the fourth aspect, since the mooring rope is provided with the adjusting band for adjusting the length of the rope,
The length of the rope can be easily adjusted.

According to the mooring ropes of claims 1 to 4, it can be used not only as a rope for mooring a floating body, but also as a rope for indicating a mark of a mooring place or a rope for towing.
