  The present invention relates to a tow rope for a pet in which a loop that is loosely wound around a neck and a lead that connects a pet collar are integrally formed by a single optical rope having a side-emitting optical fiber inserted therein. .

  Due to changes in lifestyle in recent years, an increasing number of people walk dogs at night. Also, due to the increase in paved roads, the walks are often performed on roads where vehicles pass, and along with these, accidents where dogs come into contact with those vehicles increase, making it difficult to ensure safety. It has become. This is because it is difficult to instantly recognize a dog in a low position from the driver's perspective such as a bicycle or a car. It becomes difficult.

  Conventionally, in order to ensure the safety of the pet, a method has been adopted in which a light emitting element is attached to the collar of the pet to inform the existence of the pet and ensure the safety of the pet (Patent Document 1). There is also a method of emitting light from a lead instead of a collar (Patent Document 2).

  However, when the collar is caused to emit light, the collar itself must have a power source in addition to the light emitting device, or power must be supplied from the lead portion. In the case of having a power source, the weight of the power source is larger than that of the light emitting device, and it is difficult to use the collar that emits light especially for small dogs and cats smaller than a medium-sized dog. On the other hand, when power is supplied from the lead, the collar and the lead need to be electrically connected, and the connection portion is often damaged when the pet moves around.

  In addition, when only the lead is emitted, there is a problem that the position of the pet at the tip of the lead cannot be recognized, and in the case of a method in which a light source such as an LED is embedded in the lead, the pet bites the lead. In such a case, the electric wire to the light source may be cut.

It is a whole perspective view of the tow rope for pets concerning a fifth embodiment.

Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing the overall configuration of the pet tow rope 1 according to the first embodiment, and FIG. 2 shows a case where the size of the loop portion 31 of the pet tow rope 1 is changed. FIG. 3 and FIG. 3 are partially enlarged views of the vicinity of the binding tool of the pet pulling rope tool 1. FIG. FIG. 3 shows a state in which the binding tool is divided into two parts and the upper part thereof is removed. In FIG. is there.

  The pet pulling rope 1 according to the present embodiment includes a single optical rope 3 and a handle portion 2. The optical rope 3 includes a loop portion 31 and a lead portion 32. When the entire length is extended, the length becomes about 1.5 m. The optical rope 3 is formed by inserting one side-emitting plastic optical fiber 3b and one strength cord 3c inside a transparent resin light-transmitting tube 3a. Fluorine resin is used for the cladding material of the side-emitting plastic optical fiber 3b, and special acrylic resin is used for the core material to increase the emission luminance from the side. However, the material of the plastic optical fiber 3b is not limited to this, and a material using, for example, a fully fluorinated polymer, polycarbonate, polystyrene, deuterium polymer, or the like as a core material from the viewpoint of durability or the like is also conceivable. The strength string 3b is a lightweight string member made of cloth or resin, and ensures a sufficient strength that does not break even when an impact such as a pet suddenly starts running. The optical rope 3 according to the present embodiment ensures durability by the strength cord 3c, and prevents the side-emitting optical fiber 3b in the optical rope 3 from being cut by an impact caused by the operation of the pet. .

  The loop portion 31 is formed by folding back one optical rope in the middle of the loop. One end of the optical rope 3 has tube binding means for adjusting the diameter of the loop. The tube binding means according to the present embodiment has the following configuration. That is, the first binding tool 4 that maintains the shape of the loop portion 31 and the second binding tool 5 that is fixed to the other end portion of the optical rope 3 behind the first binding tool 4 are provided. The rear side of the first binding tool 4 refers to the direction in which the handle portion 2 gripped by the user of the pulling rope tool for pets is seen from the first binding tool 4.

  The first binding tool 4 has two optical rope grooves that sandwich the optical rope 3. These grooves have a semicircular cross section. In FIG. 3, the optical rope 3 is introduced from the right second binding tool 5 into the groove located on the lower side, and after the strength string 3 c is extracted from the optical rope 3 in the first binding tool 4, the light transmitting tube The optical rope 3 composed of 3a and the side-emitting optical fiber 3b is led out to the left loop portion 31. The strength string 3c is led out to the inner side of the loop part 31 through the string groove part connected to the lower groove part, and can be connected to the collar 8 of the pet 6 by providing the hook 7 at the end part. The optical rope 3 introduced into or led out from the lower groove portion of the first binding tool 4 needs to be fixed so as not to operate relative to the first binding tool 4, and the groove portion has a diameter smaller than the diameter of the optical rope 3. Or a protrusion for fixing is formed on the surface of the groove. In FIG. 3, the optical rope 3 is introduced from the left loop portion 31 to the upper groove portion, and the optical rope 3 is led out to the right second binding tool 5. The groove located above and the optical rope 3 need to move relatively in the axial direction of the groove in order to adjust the diameter of the loop. Therefore, the diameter of the groove is slightly larger than the diameter of the optical rope 3. In addition, the two groove portions for the optical rope are configured so that the relative distances thereof open from the right to the left, that is, from the direction in which the second binding device 5 is present to the direction in which the loop portion 31 is present. With this configuration, friction is generated between the groove portion positioned above and the optical rope 3, and the diameter of the loop portion 31 can be prevented from being unduly expanded due to the operation of the pet or the like.

  The 2nd binding tool 5 also has the two groove parts for optical ropes which pinch | interpose the optical rope 3 similarly to the 1st binding tool 4. FIG. However, the groove part of the 2nd binding tool 5 becomes the following structures. In FIG. 3, the optical rope 3 from the first binding tool 4 on the left side is introduced into the groove located on the upper side, and the optical rope 3 and the second binding tool 5 are fixed so as not to move relatively. The fixing method is the same as the method adopted in the first binding tool 4. And the reflection member 9 is provided in the back side of the upper groove part inside the 2nd binding tool 5 so that it may look into one of the edge parts of the optical rope 3. As shown in FIG. In the present embodiment, in consideration of durability and the like, the reflecting member 9 is formed by depositing aluminum on plastic. In FIG. 3, the optical rope 3 from the right handle portion 2 is introduced into the groove portion positioned below, and the optical rope 3 is led out to the left first binding portion 4. The groove portion positioned below and the optical rope 3 need to move relatively in the axial direction of the groove in order to adjust the diameter of the loop. Therefore, the diameter of the groove is slightly larger than the diameter of the optical rope 3.

  A method of adjusting the diameter of the loop with the above configuration will be described with reference to FIG. FIG. 2A is a diagram showing a state where the loop diameter is large, and FIG. 2B is a diagram showing a state where the loop diameter is small. (A) When the loop diameter is large as shown in the figure, the relative distance between the first binding tool 4 and the second binding tool becomes small. From this state, the first binding tool 4 and the second binding tool 5 are each gripped by hand, and when the second binding tool 5 is moved toward the handle portion 2 so that the relative distance increases, a loop portion 31 is formed. A part of the optical rope 3 is pulled by the second binding tool, and the diameter of the loop can be reduced as shown in FIG.

  (B) When the diameter of the loop is small as shown in the figure, when the optical rope 3 of the loop part 31 and the first binding tool 4 are each gripped by hand and the optical rope 3 of the loop part 31 is pulled, (a) As shown in the figure, the loop diameter can be increased. Even when the diameter of the loop is changed and adjusted in this way, the strength string 3c is derived from the first binding tool 4, and therefore the position of the end of the strength string 3c is not affected.

  One optical rope 3 inserted through the side-emitting optical fiber 3b is folded, and a loop is formed at the folded portion, thereby connecting the loop portion 31 and the lead portion 32 formed by the side-emitting optical fiber 3b. While emitting light as a light source, the weight of the loop portion 31 wound around the pet's neck can be reduced, and it can be used for dogs and cats of medium-sized dogs and below, and the lead portion 32 and the loop portion 31 are integrated and connected. Since there is no, the durability improves as a tow rope.

  Moreover, since the end of the optical rope 3 is looked into the light source 22 in the handle part, it is not necessary to arrange a light source in the loop part 31 and the lead part 32 through which the neck is passed, and the conductor is disconnected due to the pet biting. Durability is improved in this respect as well.

  In addition, the optical rope 3 has a tube bundling means for adjusting the diameter of the loop, and the strength cord 3c inserted through the inside of the light transmissive tube 3a is extracted from the light transmissive tube 3a by the loop portion 31. By being able to connect to the collar or the like at the end of 3c, the optical fiber 3b is not subjected to an impact caused by the operation of the pet 6, and the durability is further improved. Further, the loop portion 31 can be adjusted so as to be loosely fitted around the neck of the pet 6, and in the case of a pet with long body hair, the loop portion 31 is wound so as to be exposed to the outside of the hair. If it is, the effect that the light of the loop part 31 is not disturbed by hair can be expected.

  Easy because the tube binding means includes the first binding tool 4 that maintains the shape of the loop and the second binding tool 5 that adjusts the diameter of the loop by changing the relative distance between the first binding tool 4 and the first binding tool 4. In addition, the loop diameter can be adjusted, and the excess portion of the optical rope 3 that does not constitute the loop portion 31 can be positioned so as not to interfere with the pet. In addition, the diameter of the loop cannot be changed from the pet side.

  Since the reflecting member 9 is provided inside the second binding tool 5 serving as a tube binding means so as to look into the other end of the optical rope 3, the light once transmitted can be used without any waste. In particular, the optical fiber 3b of the loop portion 31 is used. The light emission intensity of can be increased.
