[Industrial applications]

 TECHNICAL FIELD The present invention relates to a fixture for fixing a rope for supporting a tree, which is used to prevent lodging of a tree.

[0002]

[Prior art]

 Rope is usually laid to prevent the fall of fixed trees or temporary trees, or to raise trees that have been tilted due to wind and snow. FIG. 4 is a perspective view illustrating a state in which a conventional rope is stretched for a tree. As shown in this figure, the tip of the rope R is attached to the upper part of the tree T, and when the tree T stands upright, the base end of the rope R is an anchor or a bar pile with a hook provided on the ground. And the like to the anchor member 5 (anchor having a hook in FIG. 4). Since at least three ropes R are usually stretched as shown in the drawing, the fall of the tree T supported by these ropes R is effectively prevented.

[0003]

[Problems to be solved by the device]

 By the way, even if the rope R is stretched on the tree T as described above, if the rope R is stretched for a long period of time, the rope R stretches and loosens, and the rope stretching effect is reduced. Therefore, conventionally, each time the rope R is slackened, the binding between the rope R and the anchor member 5 is released for a while, and the rope R is tensioned and then bound again, but once the binding is done. It is very troublesome to unravel, and it is also troublesome to reattach the rope R in a tensioned state so as not to loosen it after releasing the binding.

The above-described re-tensioning work of the rope R does not cause any particular problem, for example, when the number of target trees is small, but there is a large amount of tens to hundreds of trees. In the case of tree planting, it takes too much manpower and time to re-tension the rope R for a large number of trees, so ropes are laid on the tree from the viewpoint of labor saving and economy. The advent of jigs to support such a long time has long been desired by those skilled in the art.

The present invention has been made in order to solve the above problems, and it is possible to easily perform rope tensioning work on trees, and even if ropes are once stretched, the ropes may be roped. It is intended to provide a rope fixing tool for supporting trees that can be re-tensioned with one touch even if the slack is loose.

[0010]

[Action]

 According to the rope fixture of the above-mentioned claim 1, when the rope is stretched on the object to be supported, first, one base end of the pair of ropes is attached to the pedestal by the tip end. The base end of the lower rope that hangs down from the second insertion hole of the swing guide after the support is bound and the tip of the other rope is locked to the anchor member fixed to the ground. By pulling the part, the swing guide moves in the direction in which the pedestal is pulled with the stopper preventing rotation around the pivot, so the other rope between the direction change guide and the anchor member is The length of the rope is shortened, and as a result, the rope fixed to the anchor member is tensioned and stretched as a whole.

That is, even if the base end portion of the other rope is pulled, the swing guide is prevented from rotating around the pivot axis by the stopper, so that the swing guide is lowered along with the lowering of the rope. In the end, the other rope can slide through the first insertion hole and the second insertion hole of the swinging guide without great resistance, and the rope can be strained without any bearing. Can be done.

[0012] Once the rope is stretched as described above, this tensioned rope will not move between the direction change guide and the anchor member of the other rope when an external force is applied in the extending direction. Since the rope between them moves downward relative to the pedestal so that it becomes longer, this relative movement causes the rocking guide to be entrained in the rope and rotate around the pivot axis, and the first insertion hole and the second insertion hole. The rotation of the swinging guide around the pivot is prevented in a state where the inner edges of the upper and lower diagonals of the shaft are abutted on the rope. Then, since the rope is in a state of biting into the corner of the inner edge portion, it does not slide through the first insertion hole and move, and as a result, the once-tensed rope does not relax.

According to the rope fixing device of the second aspect, the pair of ropes includes an upper rope that is bound to the tip side of the tree and a lower rope that is locked to an anchor member provided on the ground. Since the upper rope is tied to the tip side of the tree and the lower rope is tied or locked to the anchor member, the rope tensioning operation described above is performed. It can be conveniently applied to growing and managing trees.

According to the rope fixture of the third aspect, the direction changing guide is composed of a guide pulley rotatably supported around a support shaft provided on the pedestal. Therefore, when the lower rope is pulled to pull the tip of the lower rope to tension the rope, the guide pulley rotates around the support shaft along with the movement of the lower rope. The resistance is greatly reduced and the rope can be tensioned more smoothly.

According to the rope fixing device of the fourth aspect, since the rope fixing holes for fixing the upper rope and the lower rope are provided at the uppermost portion and the lowermost portion of the pedestal, the upper rope and the lower portion are fixed. The upper rope and the lower rope can be easily attached to the pedestal by inserting the ropes into the fixing holes and forming the knots at their tips.

According to the rope fixing device of the above-mentioned claim 5, since the pair of ropes including the upper rope and the lower rope are integrally provided on the back surface of the pedestal, the ropes are connected to the upper rope and the lower rope. It can be done with one rope without splitting.

【Example】

 FIG. 1 is a perspective view showing an example of a rope fixing device according to the present invention. Although the figure illustrates a rope fixing device applied to a tree supporting rope, the rope fixing device of the present invention is not limited to a tree supporting rope, but it is for a construction site or a temporary structure. It can also be applied to other uses that require rope laying, such as for support.

As shown in FIG. 1, the rope fixture M of the present invention basically comprises a flat base 1 and a tree support rope 6 attached to the base 1.

The pedestal 1 is usually made of steel plate, but is not limited to steel plate and may be made of synthetic resin or wood. Since it is cheaper if it is made of synthetic resin or made of wood, it can be used in a disposable manner. In this embodiment, a vertically long rectangular steel plate is used, and its surface is coated for rust prevention.

The tree support rope 6 has a lower end in which an upper rope 61 whose tip side is bound to a tree and a first folded portion 63 formed by folding back the tip side are locked to an anchor member 5 provided on the ground. And a rope 62. The material of these ropes is not particularly specified, and synthetic resin ropes such as polyethylene, polypropylene, and polyamide, and natural fiber ropes such as cotton and hemp made of natural fibers are available. It is preferably used, but not limited to such a fiber rope, a straw rope or the like can be used.

In the present embodiment, the lower rope 62 is attached to the pedestal 1 in a state where the base end portion of the lower rope 62 is inserted into the rope fixing hole 13 and a knot is formed at the tip. The attachment method is not limited to this, and the front end portion of the lower rope 62 may be directly bonded to the anchor member 5.

On the upper part and the lower part of the flat base 1 as described above, the base end side parts of the upper rope 61 and the lower rope 62 are attached, respectively. That is, the upper rope fixing hole 12 is formed at the uppermost portion of the pedestal 1, the lower rope fixing hole 13 is formed at the lowermost portion thereof, and the upper rope fixing hole 12 is provided with the upper rope 61. Similarly to the above, the base end portion and the base end portion of the lower rope 62 are inserted into the lower rope fixing hole 13 from the rear surface to the surface of the base 1, and a knot is formed at the tip end. Therefore, even if the rope fixing hole 12 and the rope fixing hole 13 are pulled in opposite directions by sandwiching the pedestal 1, the ropes 61 and 62 are prevented from coming off the rope fixing holes 12 and 13 by being blocked by the knot.

The base end portion of the upper rope 61 and the base end portion of the lower rope 62 may be connected to each other, or may be originally formed as a single rope without being divided into the upper rope 61 and the lower rope 62. Good. When they are connected to each other, the upper rope 61 is passed from the surface of the pedestal 1 through the upper rope fixing hole 12 and the lower rope 62 is likewise passed through the rope fixing hole 13 so that they are bound together on the back surface of the pedestal 1. Good. Further, in order to cover the upper rope 61 and the lower rope 62 with one rope, the rope is inserted from the surface of the pedestal 1 into the upper rope fixing hole 12, and this time, this rope is moved from the rear surface of the pedestal 1 to the lower rope. It suffices to insert a corresponding length into the surface of the pedestal 1 by inserting it into the fixing hole 13 and use the extracted rope as the lower rope 62.

A horizontally long swing guide 3 is provided at a substantially central portion of the pedestal 1. The swinging guide 3 is rotatably supported around a pivot 31 fixed to the pedestal 1 by penetrating its central portion. A first insertion hole 32 for inserting the lower rope 62 is provided on the left side of the swing guide 3 with respect to the pivot 31, and a second insertion hole 33 is similarly provided on the right side. . A stopper 4 for preventing the swing guide 3 from rotating clockwise around the pivot 31 is provided on the lower surface of the swing guide 3 on the side where the second insertion hole 33 is provided. It is provided.

In this embodiment, the swing guide 3 is swingably supported by the pivot 31 at the substantially central portion thereof, but the swing guide 3 is not particularly limited to the central portion, and is dependent on the shape of the pedestal 1. The shaft may be supported at an eccentric position.

A direction changing guide 2 for changing the direction of the lower rope 62 is provided on the surface of the base 1 and slightly above the swing guide 3. In the case of the present embodiment, the direction changing guide 2 is constituted by a guide pulley 2a which is fixed on the surface of the pedestal 1 and rotates around a support shaft 21.

Then, the lower rope 62 is inserted from the tip thereof into the first insertion hole 32 of the swing guide 3 as described above, and the guide pulley as the direction change guide 2 provided on the swing guide 3 is provided. It is suspended by 2a, folded back, and inserted into the second insertion hole 33 of the swing guide 3 this time, and the tip end portion is pulled out from the second insertion hole 33 to the extent that it can be gripped.

In the present embodiment, the guide pulley 2a that rotates around the support shaft 21 is used as the direction changing guide 2, but the guide pulley 2a is not limited to such a guide pulley 2a and may be, for example, an upper portion. Any member may be used as long as it can guide the lower rope 62 to change its direction, such as fixing an arcuate member having a curved surface.

A C-shaped guide guide 11 is provided at the center of the lowermost portion of the surface of the pedestal 1 by welding both sides of the guide guide 11 to the surface of the pedestal 1. The lower rope 62 is also inserted through this guide guide 11.

Therefore, the lower rope 62 is inserted into the rope fixing hole 13 from the surface of the pedestal 1 and folded back at the lower portion to form the first folded portion 63, and the first insertion portion of the guide guide 11 and the swing guide 3 is inserted. The second folded portion 64 is formed by being inserted through the hole 32 and further folded back along the upper arc of the guide pulley 2a, and finally inserted through the second insertion hole 33 of the swing guide 3 and eventually the rope fixing hole. A vertically elongated ring starting from 13 and ending at the second insertion hole 33 is formed.

The operation of the present invention will be described below with reference to FIGS. 2 and 3. FIG. 2 is a partial cross-sectional front view of the rope fixture M of FIG. 1, showing a state in which the tip end of the lower rope is pulled downward as indicated by arrow F1. As shown in this figure, when the tree support rope 6 is stretched between the tree and the anchor member 5 (not shown), first, the tip end of the upper rope 61 (not shown) is bound to the upper part of the tree. . Then, the first folded-back portion 63 of the lower rope 62 is locked to the anchor member 5 fixed to the ground. Then, in this state, when the tip end portion of the lower rope 62 hanging downward from the second insertion hole 33 of the swing guide 3 is pulled downward, the lower rope 62 passes through the first insertion hole 32 of the swing guide 3. Since it is folded back by the guide pulley 2a and moves downward through the second insertion hole 33, the interval between the second folded portion 64 and the first folded portion 63 of the lower rope 62 is narrowed, and the tree support rope 6 is eventually The tension between the outside tree and the anchor member 5 is increased.

In this case, the lower rope 62 and the inner peripheral surfaces of the first insertion hole 32 and the second insertion hole 33 of the swing guide 3 slide to rotate the swing guide 3 around the pivot 31 in the clockwise direction. However, since a stopper 4 is provided on the pedestal 1 on the outer side of the lower portion of the second insertion hole 33, the stopper 4 is stopped to prevent the swing guide 3 from rotating clockwise. As a result, the lower rope 62 moves in the pulling direction (downward) so as to slide through the first and second insertion holes 32 and 33.

FIG. 3 is a partial cross-sectional front view of the rope fixture M, showing a state where the tree support rope 6 has been stretched. In this case, due to the restoring force of the tensioned tree support rope 6, a force as indicated by an arrow F2 acts on the first folded portion 63 of the lower rope 62 locked to the anchor member 5, As a result, the lower rope 62 between the guide pulley 2a and the anchor member 5 is pulled downward. At that time, the rocking guide 3 is rotated counterclockwise around the pivot 31 so that the first insertion hole 32 and the second insertion hole 32 With the lower rope 62 resting on the diagonal edge of the insertion hole 33, the rotation of the swing guide 3 is blocked.

Therefore, in such a state, since the lower rope 62 bites into the edge portions of the corners of the first insertion hole 32 and the second insertion hole 33, the downward movement of the lower rope 62 does not occur. Blocked, the tree support rope 6 is in a state of not relaxing.

As described in detail above, the present invention is constructed so that the swing guide 3 into which the lower rope 62 is inserted does not rotate around the pivot 31 in the direction in which the tip of the lower rope 62 is pulled by the stopper 4. Since the swing guide 3 is rotated, the lower rope 62 is not pressed. Therefore, when the tree support rope 6 is stretched, the tree support rope 6 is tensioned by pulling the tip of the lower rope 62. However, once stretched, the swing guide 3 rotates around the pivot 31 in the direction in which the stopper 4 does not work and presses the lower rope 62, preventing the tree support rope 6 from slackening, and eventually It is possible to perform tensioning work of the tree support rope 6 and re-tensioning work when the tree support rope 6 is loosened with one-touch without the need to tie the rope like that, which is extremely convenient for labor saving. .

[Effect of device]

 As described above, the rope fixing device of the present invention is a rope fixing device that is installed between a pair of ropes to adjust the length of the rope, and includes a pedestal, a direction conversion guide attached to the pedestal, and a swinging device. The swing guide is provided so as to swing around a pivot provided on the pedestal, and is configured to be prevented from swinging in one direction by the stopper means. The guide is formed with a first insertion hole and a second insertion hole through which the rope is inserted on both sides of the pivot. After one end of the rope is inserted into the first insertion hole, the direction changing guide is inserted. When the end of the rope is pulled, the stopper acts, and when the opposite side of the end of the rope is pulled, the swing guide swings around the pivot and For insertion hole and second insertion hole Movement of the rope is arranged to be prevented Ri.

Therefore, when the rope is stretched on the supported object, the supported object is first bound at one end of the pair of ropes, and the other end of the rope is fixed to the ground. After locking to the anchor member, pulling the base end of the lower rope that hangs downward from the second insertion hole of the rocking guide, the rocking guide is blocked by the stopper from rotating around the pivot axis. Since the pedestal moves in the pulled direction, the other rope between the direction change guide and the anchor member becomes shorter, and the first folded portion of the lower rope is eventually locked by the anchor member. The rope is in a generally tensioned and adjusted state.

Then, once the rope is stretched as described above, when the stretched rope receives an external force in a direction in which the rope extends, the rope changes from the direction change guide of the other rope to the anchor member. Since the rope between the ropes moves downward relative to the pedestal so that it becomes longer, this relative movement causes the rocking guide to be entrained in the rope and rotate around the pivot axis, and the first insertion hole and the second insertion hole. Rotation of the swing guide around the pivot axis is prevented with the diagonal inner edges of the upper and lower holes hitting the rope. Then, since the rope is in a state of biting into the corner of the inner edge portion, it does not slide through the first insertion hole and move, and as a result, the once-tensed rope does not relax.

As described above, in the rope fixing device of the present invention, in order to re-tension the loosened rope, only pulling the tip of the lower rope is necessary, and once the binding is released once again as in the conventional method. There is no need for complicated and troublesome operations such as tensioning and then reattaching, and when performing tensioning work for a large number of supported objects, a lot of manpower and time are required. It saves money, saves labor, and is economically advantageous.

If the above-mentioned pair of ropes is composed of an upper rope that is bound to the tip side of the tree and a lower rope that is locked to an anchor member provided on the ground, the upper rope By tying the rope to the tip side of the tree and tying or locking the lower rope to the anchor member and then performing the above-mentioned rope tensioning operation, the fall of the tree can be easily prevented. It is convenient because it can be effectively applied to growing and managing trees.

If the above-mentioned direction changing guide is constituted by a guide pulley rotatably supported around a support shaft provided on the pedestal, when the lower rope is pulled to tension the rope by pulling the tip of the lower rope. As the guide pulley rotates around the support axis as it moves, the resistance to movement of the rope at the second folded portion is greatly reduced, and the rope can be tensioned more smoothly, which saves labor. This is advantageous.

If rope fixing holes for fixing the upper rope and the lower rope are provided at the uppermost and lowermost portions of the pedestal, the upper rope and the lower rope are inserted through the fixing holes, respectively, and the By forming a knot at the tip, the upper and lower ropes can be easily attached to the pedestal, which is convenient.

Further, if the upper rope and the lower rope are integrally connected on the back surface of the pedestal, it is possible to use one rope without dividing the rope into the upper rope and the lower rope. convenient.
