Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord and a method for binding an annulus to the cord, which can be stretched in a tension state very easily between two columns.

[0002]

2. Description of the Related Art Stretching a rope between two columns for the purpose of hanging or hanging a certain object has been conventionally performed in various fields. For example, at home, a rope called a washing rope is stretched around a garden or a veranda to hang laundry. Also, in order to keep the pet dog connected so that it can freely walk around in the garden, a rope is stretched between suitable struts such as two trees,
It has been practiced to hook the tip of a rope extending from the dog collar through a running tool such as a pulley.

By the way, looking at commercially available cords used for such a purpose, for example, a short cord has a length of 3 m or 5
Most of them are very long, such as 50 m or 100 m for long ones.

In addition, a ring is sometimes used to attach the end of the rope to the column, and at that time, the end of the rope is tied to the ring.

[0005]

However, the place where the rope is to be stretched, that is, the distance between the columns is practically not a proper length,
Therefore, the user is forced to purchase a rope that is longer than the distance between the columns and adjust the length of the rope to match the distance between the columns when stretching. In this case, usually, one end of the rope is tied to one strut, and the other end is wound around the other strut or the proper position of the other end is tied to the strut to adjust the length of the rope. , It is difficult to tension the cord by such a method, and it becomes more remarkable as the length of the cord becomes longer.

When a ring is used to stretch the cord between the columns, the cord is conventionally directly connected to the ring.
When the frictional force between the material of the cord and the material of the annulus is small, the knot may be unraveled naturally when a very large tension is applied to the cord. In particular, this was remarkable when the cord was made of chemical fiber and the ring was made of metal.

On the other hand, the work of connecting the end of the cord to the ring is troublesome, and once it is connected, it is often difficult to solve and there is a problem in terms of ease of handling. The present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to provide a cord and a method for binding an annulus to the cord that can be tensioned between two columns very easily. It is a thing.

[0008]

The cord according to the present invention is
A cord body, one moving ring, first and second retaining rings, and one locking tool formed by juxtaposing a pair of insertion holes through which the cord body can be inserted. , A fixing member that is slidably and fixedly attached to the cord body, a moving ring is attached to the cord body at an appropriate position midway, and one end side of the moving ring of the cord body has a constant length. Part and the other end side are variable length parts, the constant length part is inserted into one of the insertion holes of the locking tool, and the first retaining ring is attached to the tip end of the constant length part. , The variable length portion of the cord body is bridged at least two reciprocations between the moving ring and the second retaining ring, and the variable length portion is inserted into the other insertion hole of the locking tool. Further, a fixing tool is mounted between the tip of the variable length portion and the locking tool.

Further, the method of binding a ring body to a cord body according to the present invention prepares a binding tool in which a pair of cord body insertion holes having an inner diameter slightly larger than the diameter of the cord body are arranged in parallel. , The cord is inserted into one of the cord insertion holes and the annulus of the binding device one by one, and then the tip of the cord is inserted into the other cord insertion hole of the binding device, and finally the cord is inserted. It is characterized by forming a knot at an arbitrary position on the tip of the body.

[0010]

The operation of the present invention will be described with reference to FIGS. 1 to 3 showing an embodiment of the present invention and FIG. 4 which is an equivalent diagram showing the principle of the present invention.

In this example, the variable length portion 9 of the cord body 1 is
Spans between the moving ring 2 and the second retaining ring 4 so as to make two reciprocating movements.

First, the first retaining ring 3 and the second retaining ring 4 are hooked at appropriate positions on columns (not shown) (see FIG. 1). In this state, the cord is hung downward.

Next, as shown in FIG. 2, the grip ring 13 attached to the distal end portion 16 of the variable length portion 9 of the cord body 1 is gripped and pulled toward the first latch ring 3. Then, the first and second
Since the retaining rings 3 and 4 are fixed to the column, the moving ring 2 moves so as to be pulled toward the second retaining ring 4 side, and accordingly, the fixed length of the rope body 1 is fixed. The portion 8 is also pulled toward the second retaining ring 4 side. At this time, since the variable length portion 9 of the rope body 1 bridges between the moving ring 2 and the second retaining ring 4 so as to reciprocate twice, the constant length portion 8 is changed to the variable length portion 9 You will be pulled with three times the force of pulling. In other words, the cord body 1 can be tensioned between the columns with a force that is one-third of the force required to stretch the cord body 1 between the columns. Further, the moving distance of the moving ring 2 to the second retaining ring 4 side is one third of the length of pulling out the grip ring 13.
Becomes That is, the grip ring 13 is pulled by an amount corresponding to a length three times the moving distance of the moving ring 2.

This principle is shown in FIG. That is, the second retaining ring 4 corresponds to the two constant pulleys A and B, and the moving ring 2 corresponds to the moving pulley C. Then, the variable length portion 9 of the cord body 1 is
The tip is fixed to the moving pulley C, and the fixed pulley A,
The movable pulley C and the constant pulley B are wound in this order. Further, the force required to tension the cord body 1 in a tension state corresponds to the force F applied to the shaft portion of the movable pulley C. Therefore,
The force f required to pull the tip of the variable length portion 9 of the rope body 1 to balance this force F is three because the number of ropes wound around the movable pulley C is three. One third of
Becomes Further, in order to raise the movable pulley C upward by the distance T, the tip portion of the variable length portion 9 is lowered by three times, that is, 3T.

Thus, by pulling the variable length portion 9 of the rope body 1 with a little force, it is possible to tension the rope body 1 between the columns in a tensioned state.

When the cord body 1 has been stretched,
As shown in FIG. 3, the fixing device 14 mounted on the distal end portion 16 of the variable length portion 9 is moved until it hits the locking device 5 (the drawing shows the position where the fixing device 14 just hits the locking device 5). Let As a result, the locking tool 5 is locked to the fixing tool 15, and the cord body 1 is maintained in a tensioned state.

When the variable length portion 9 of the rope body 1 is reciprocated between the moving ring 2 and the second retaining ring 3 three times, the variable length portion 9
The pulling force f is one fifth of the force F, and
Is 5 times the distance T.

Next, the operation of the invention of claim 2 will be described with reference to FIG. 7 showing an embodiment of the present invention.

The binder 14 has a pair of cord insertion holes 141 and 142 having an inner diameter slightly larger than the diameter of the cord 1 arranged in parallel. The cord body 1 is sequentially inserted into one of the cord body insertion holes 141 and the ring body 13 of the binder 14, and then the tip end portion 16 of the cord body 1 is inserted into the other cord body insertion hole 14 of the binder 14.
The knot 15 is inserted through the cord 2, and finally the knot 15 is formed at an arbitrary position on the tip portion 16 of the cord 1.
Is caught in the cord insertion hole 142 of the cord 1, and the tip portion 16 of the cord 1 is caught.
Will be linked to the ring 13. Here, when tension is applied to the cord 1, the force is applied to the knot 15 and the binder 14.
Will be received at the abutting portion with the abutment portion and the abutting portion between the binding tool 14 and the ring body 13. Moreover, since there is no material other than the cord 1 intervening in the knot 15, the cord 1 is not inserted in this portion.
Does not slip. Therefore, no matter how much tension is applied to the cord 1, the knot 15 will not be unraveled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show the structure of a cord according to the present invention, FIG. 1 is a front view showing a state before tensioned state, FIG. 2 is a front view showing a state in which tensioned state is being stretched, FIG. [Fig. 3] is a front view showing a state just before the tension is finished.

This cord is composed of one cord body 1, one moving ring 2, first and second retaining rings 3 and 4, one locking tool 5, and one locking ring. The main part is composed of the fixing tool 6 and the other two binding tools 11 and 14 and the grip ring 13.
And are provided.

A moving ring 2 is attached to the cord body 1 at an appropriate position midway thereof, and one end side of the cord body 1 of the moving ring 2 is a fixed length portion 8 and the other end side is a variable length portion 9, which has a fixed length. The part 8 is inserted into one of the insertion holes 51 of the locking tool 5, and the first retaining ring 3 is bonded to the tip of the constant length part 8, while the variable length part of the cord body 1 is connected. 9 is reciprocally bridged between the movable ring 2 and the second retaining ring 4, and the variable length portion 9 is inserted into the other insertion hole 52 of the locking tool 5, and the variable length portion 9 is further inserted. The tip 16 of
A fixing tool 14 is mounted between the locking tool 5 and the locking tool 5, and a grip ring 13 is attached to the tip portion 16.

The cord body 1 may be made of chemical fiber or natural fiber, or may be made of metal such as wire, or any other known material. The length is arbitrary. In this example, chemical fiber is used.

The method of attaching the movable ring 2 to the cord body 1 is to simply connect the cord body 1 to the movable ring 2, and no other parts are used. The binding position of the moving ring 2 is determined in consideration of the ratio of the constant length portion 8 and the variable length portion 9. If this position is determined so that the variable length portion 9 becomes long, the cord body has a wide length adjustment range, and conversely, if it is determined that the variable length portion 9 becomes shorter, the length adjustment range becomes longer. It will be narrow. In any case, the binding position of the moving ring 9 may be appropriately determined so as to have a length according to the place of use, taking into consideration the total length of the cord body 1.

The moving ring 2 has a circular shape. The material of the moving ring 4 may be either metal or synthetic resin, but metal is preferable from the viewpoint of strength. The shape of the moving ring 4 is not limited to this example, and may be an arbitrary shape such as a triangle or a quadrangle, or a polygon or an ellipse.

The first retaining ring 3 is formed in a substantially trapezoidal shape, and a hook 10 is attached to one end of the first retaining ring 3 so as to be rotatable around its axis. The material of the retaining ring 3 may be either metal or synthetic resin, but metal is preferable from the viewpoint of strength. The shape of the retaining ring 3 is not limited to this example, and the hook 10 is not essential.

The second retaining ring 4 is formed in a circular shape. Similar to the first retaining ring 3, the retaining ring 4 may be made of metal or synthetic resin, but is preferably made of metal in terms of strength. In addition, this latch ring 4
However, the shape is not limited to this example. Further, a hook may be attached to the same as the first retaining ring 3 described above.

As shown in FIG. 5, the locking member 5 is a small block-like member in which a pair of insertion holes 51 and 52 through which the cord body 1 can be inserted are arranged. The material of the locking tool 5 may be either metal or synthetic resin, but metal is preferable from the viewpoint of strength.

The fixture 6 is slidably and fixedly attached to the cord body 1. The structure of the fixing tool 6 is the same as that of the locking tool 5 described above, and thus detailed description thereof will be omitted. When the cord body 1 is attached to the cord body 1, the cord body 1 is attached to the insertion holes 6 of the fixture 6 as shown in FIG.
Insert it so that it sews 1, 62. As a result, the fixture 6 engages with the opening edge portions of the insertion holes 61 and 62, and is fixed at a desired position. When the fixture 6 is slid with respect to the rope body 1, the U of the rope body 1
The character portion 91 is pulled out to release the engagement, and the character portion 91 is moved to a predetermined position.

The grip ring 13 has the same structure as the second retaining ring 4 described above. This grip ring 13 is the cord body 1
It is provided to facilitate the pulling of the variable length portion 9 and is not essential. The tip 16 of the variable length portion 9 of the cord body 1 is bonded to the grip ring 13 as shown in FIG. Although the embodiment shown in this figure relates to the invention of claim 2 of the present application, it will be described here for convenience of description.

In FIG. 7, reference numeral 14 indicates a binding tool. This binding tool 14 includes the locking tool 5 and the fixing tool 6 described above.
A pair of insertion holes 141 and 142 are arranged in parallel with each other. The inner diameters of these insertion holes 141 and 142 are
The size is set so that the cord body 1 can be inserted and the knot 15 formed in the cord body 1 can be engaged.

In order to bind the cord body (variable length portion 9 of the cord body 1) to the ring body (grasping ring 13) using the binder 14 thus configured, one of the binders 14 After sequentially inserting the cord body 9 into the cord body insertion hole 141 and the ring body 13, the distal end portion 1 of the cord body 9 is inserted.
6 is inserted into the other cord insertion hole 142 of the binding tool 14, and finally a knot 15 is formed at an arbitrary position of the tip portion 16 of the cord 9. The knot 15 is usually a so-called dumpling knot, but the number of times of the knot may be once or twice or more.

In this way, the tip of the cord 9 is attached to the ring 1.
When tied to the cord 3, the knot 15 is hooked on the cord insertion hole 142 of the binder 14, so that the tip portion 16 of the cord 1 is tied to the ring body 13. Here, when tension is applied to the cord 1, the force is received at the contact portion between the knot 15 and the binding tool 14 and at the contact portion between the binding tool 14 and the ring body 13. Moreover, since no material other than the cord 1 is intervening in the knot 15, the cord 1 does not slip in this portion. Therefore, no matter how much tension is applied to the cord 1, the knot 15 will not be unraveled.

The same method as this is applied to the constant length portion 8 of the main body 1 of the cord.
It is also used to bond the tip of the to the first retaining ring 3.
The binding tool used here is denoted by reference numeral 11.

According to this method, it is possible to adjust the length of the cord by simply changing the position of the knot formed at the tip of the cord.

Next, a method of using the cord according to the present invention will be described.

First, the first retaining ring 3 and the second retaining ring 4 are hooked at appropriate positions on columns not shown. In this state, the cord is hung downward (see FIG. 1).

Next, as shown in FIG. 2, the grip ring 13 located at the tip of the variable length portion 9 of the cord body 1 is gripped and pulled toward the first retaining ring 3. Then, since the second retaining ring 4 is fixed to the column, the moving ring 2 moves so as to be pulled toward the second retaining ring 4 side, and accordingly, the cord body 1 is moved. The constant length portion 8 is also pulled toward the second retaining ring 4.
At this time, since the variable length portion 9 of the rope body 1 bridges between the moving ring 2 and the second retaining ring 4 so as to reciprocate twice, the constant length portion 8 is changed to the variable length portion 9 You will be pulled with three times the force of pulling. In other words, the cord body 1 can be tensioned between the columns with a force that is one-third of the force required to stretch the cord body 1 between the columns. Further, the moving distance of the moving ring 2 toward the second retaining ring 4 side is one third of the length of pulling out the grip ring 13. That is, the moving ring 2
The holding ring 13 corresponding to the length of three times the moving distance
Will be pulled.

In this way, by pulling the variable length portion 9 of the cord body 1 with a small force, it becomes possible to tension the cord body 1 between the columns in a tensioned state.

When the cord body 1 has been stretched,
As shown in FIG. 3, the fixing tool 14 attached to the tip of the variable length portion 9 hits the locking tool 5 (the drawing shows the fixing tool 14).
Is on the verge of hitting the locking tool 5). As a result, the locking tool 5 is locked to the fixing tool 15, and the cord body 1
Will maintain tension.

In the above embodiment, the variable length portion 9 of the rope body 1 is reciprocated between the moving ring 2 and the second retaining ring 4 twice, but the present invention is not limited to this. Instead, it may be three round trips or more. When reciprocating three times, the pulling force of the variable length portion 9 is 1/5 of the force required to pull the cord body 1 tightly between the columns, and the distance to pull the variable length portion 9 is
This is five times the moving distance of the moving ring 2.

[0043]

As described above, the cord according to the present invention is as simple as pulling the variable length portion of the cord body without separately adjusting the length according to the distance between the two columns. It is extremely easy to pull in tension with various operations.

In addition, since the variable length portion is bridged between the moving ring and the second retaining ring for two or more reciprocations, the pulling force of the variable length portion is small, and even a weak woman or child can use it. It can be stretched easily.

According to the method of binding the ring body to the end portion of the cord body according to the present invention, the cord body and the ring body can be firmly bound, and the tension applied to the cord body is large. There is no fear that the bond will come loose.

In addition, since it is sufficient to simply tie a knot on the cord side, anyone can easily work, and the size of the cord can be easily adjusted only by changing the position of the knot.
