Description

  The present invention relates to a towing rope for a pet in which a loop wound around a neck and a lead connecting a pet are integrally formed by a single optical rope made of a side-emitting plastic optical fiber.

  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, walks are often carried out on roads where cars and bicycles pass, and as a result, the number of accidents where dogs come into contact with cars, etc., increases, ensuring safety. It's getting harder. This is because it is difficult to recognize a dog at a low position from the viewpoint of a driver of a car or the like instantaneously, especially in the case of a dog of a medium size or less, making it more difficult to recognize its existence. Become.

  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 emits light, the collar itself needs to 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 a light-emitting collar having a power source especially for small dogs and cats smaller than medium-sized dogs. 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 emits light, 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 emitter such as an LED is embedded in the lead, the pet becomes the lead. When it bites, there exists a possibility that the electric wire to the luminous body may be cut.
