Abstract

<P>PROBLEM TO BE SOLVED: To provide a lead for a pet animal that is made of an expandable rope in almost all parts of the rope except the clasp part and the grip part. <P>SOLUTION: In this lead for pet animal, a thermally shrinkable tube A that can be expanded larger than the outer diameter D of the rope 1 and is thermally shrinkable to less than the outer diameter of the rope 1 is mounted to the rope 1 at the diameter-expanded state before the thermal shrinkage and tightly wound around a cylinder having an appropriate diameter and the tube A is thermally shrunk as it is wound around the tube whereby the tube A is allowed to be tightly stuck to the rope 1. Then, they are cooled down to the freezing temperature of the memory material of the thermally shrinking tube A to form a helical spring part B and simultaneously a hook member 3 is connected to one end of the rope 1 communicating to the helical spring part B and a ring-form grip 4 is connected to the other end. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明はペット用引き綱に関するものである。 The present invention relates to a pulling rope for pets.

犬、猫、猿等のペットを散歩させるとき、ペットが不規則に動き回るため、ペット用引き紐が人やペットに絡まり付くという不具合が生じていた。この不具合を解消するために、引き綱の一部にゴム紐を介在させ、ゴム紐の伸び縮みによって、前記絡み付きを防止しようという試みがなされていた（例えは、特許文献１参照。）。 When pets such as dogs, cats, monkeys, etc. walk, the pets move around irregularly, causing a problem that the drawstring for the pet gets entangled with people and pets. In order to solve this problem, an attempt has been made to prevent the entanglement from occurring by interposing a rubber string in a part of the drawstring and stretching or contracting the rubber string (for example, see Patent Document 1).

しかし、この試みは、絡み付き防止には、若干の効果を呈するが、引き綱の大部分が伸縮ができないロ−プで構成されていたので、前記不具合を全て解消することはできないという問題点があった。
特願平９−１４９７０号公報 However, this attempt has some effect in preventing entanglement, but since most of the tow rope is composed of a loop that cannot be expanded and contracted, there is a problem that all of the above problems cannot be solved. there were.
Japanese Patent Application No. 9-14970

この発明は、背景技術で記述した問題点を解消するためになされたもので、留め金部と握り部を除き、引き綱部のほぼ全体が伸縮できるペット用引き綱の提供を目的とするものである。 The present invention has been made to solve the problems described in the background art, and an object thereof is to provide a towline for a pet that can expand and contract almost the entire towline part except for a clasp part and a grip part. It is.

この発明のペット用引き紐は、ロ−プの外径以上に拡径され、加熱収縮させたとき、前記ロ−プの外径以下に収縮する加熱収縮チュ−ブを、加熱収縮させる前の拡径した状態で、前記ロ−プに装着し、適宜外径の円筒体に密接して巻き付け、巻き付けた状態で、前記加熱収縮チュ−ブを加熱収縮させ、前記ロ−プに密着させたのち、前記加熱収縮チュ−ブのメモリ−材の凍結温度まで冷却し、前記円筒体を除去して、弦巻ばね状部を形成させるとともに、該弦巻ばね状部に連通する前記ロ−プの一端部に留め金部材を取付け、他端部にわっぱ状の握り部を設けていることを特徴とするものである。 The pet drawstring of the present invention is expanded before the outer diameter of the rope, and when heat-shrinked, the heat-shrinkable tube that contracts below the outer diameter of the rope is heated and contracted. In the expanded state, it was attached to the rope, and was wrapped in close contact with a cylindrical body having an appropriate outer diameter, and in the wound state, the heat-shrinkable tube was heat-shrinked and brought into close contact with the rope. Thereafter, the memory material of the heat shrinkable tube is cooled to the freezing temperature, and the cylindrical body is removed to form a string-wound spring-shaped portion, and one end of the rope communicating with the string-wound spring-shaped portion A clasp member is attached to the part, and a wrinkle-shaped grip part is provided at the other end part.

この発明は上述のように構成されているので、次のような効果を呈する。
（１）引き綱部のほぼ全体が伸縮可能な弦巻ばね状に形成されているので、例えば、直径が１ｃｍのロ−プに、加熱収縮チュ−ブを装着し、直径が約３ｃｍの弦巻ばねを２０タ−ン形成させると、１タ−ンの直線長は約９ｃｍになり、２０タ−ン全てを直線状に伸ばすと、約１．８ｍの長さになる。この場合、弦巻ばね部の全長は、加熱収縮後の加熱収縮チュ−ブの厚さを約１ｍｍとすると、約２８ｃｍとなるので、約１．８ｍの引き綱のロ−プを、約２８ｃｍの長さに短縮（本例の場合は、約１／６）して使用することができるので、ペットや人への絡まりを確実に防止できる。当然のことながら、弦巻ばねの直径を大きくすると、さらに短縮させることができる。
（２）弦巻ばね状部は、加熱収縮チュ−ブのメモリ−材の凍結温度まで冷却し、弦巻ばね状の形状に凍結させているので、形状記憶性を備えており、弦巻ばね状部に引っ張り力を加え、引き延ばしても、引っ張り力を除去すると、元の形状に復帰し、収縮する。
（３）ペットが人から離れると、弦巻ばね状部が伸び、近づくと、弦巻ばね状部が縮み、ペットの動きに自動的に対応し、引き綱の弛みが生じないので、人やペットへの絡まり付きを確実に防止できる。 Since the present invention is configured as described above, the following effects are exhibited.
(1) Since almost the entire towline portion is formed in a string-wound spring shape that can be expanded and contracted, for example, a heat-shrinkable tube is attached to a rope having a diameter of 1 cm, and a string-wound spring having a diameter of about 3 cm. When 20 turns are formed, the straight length of one turn is about 9 cm, and when all 20 turns are straightened, the length is about 1.8 m. In this case, the total length of the string spring portion is about 28 cm when the thickness of the heat-shrinkable tube after heat-shrinking is about 1 mm, so that the rope pulling rope of about 1.8 m is about 28 cm. Since the length can be shortened (in the case of this example, about 1/6), it can be reliably prevented from being entangled with pets or people. Naturally, if the diameter of the string spring is increased, it can be further shortened.
(2) The string-wound spring-like portion is cooled to the freezing temperature of the memory material of the heat shrinkable tube and frozen in the shape of the string-wound spring-like shape. Even if a pulling force is applied and stretched, if the pulling force is removed, it returns to its original shape and contracts.
(3) When the pet moves away from the person, the string-wound spring-like portion expands. When the pet approaches, the string-wound spring-like portion shrinks and automatically responds to the movement of the pet. Can be reliably prevented from being tangled.

留め金部と握り部を除き、引き綱部のほぼ全体が伸縮できるペット用引き綱の提供という目的を加熱収縮チュ−ブを使用し、引き綱部に形状記憶性の弦巻ばね状部を形成させることにより実現できた。 A heat-shrinkable tube is used for the purpose of providing a towline for pets that can expand and contract almost the entire pulling line part, except for the clasp part and grip part, and a string memory spring-shaped part with shape memory is formed on the pulling line part It was possible to realize it.

この発明の実施の一例を図面を参照しながら説明する。ロ−プ１の外径Ｄ以上に拡径され、加熱収縮させたとき、ロ−プ１の外径Ｄ以下に収縮する加熱収縮チュ−ブＡを、加熱収縮させる前の拡径した状態で、図１に示すように、ロ−プ１に装着する。 An embodiment of the present invention will be described with reference to the drawings. When the diameter of the heat shrinkage tube A is expanded to be larger than the outer diameter D of the rope 1 and is heated and shrunk, the heat shrinkable tube A which is shrunk to be smaller than the outer diameter D of the rope 1 is expanded in diameter before being heat shrunk. As shown in FIG.

なお、加熱収縮チュ−ブＡとしては、シリゴ−ンゴム、ＥＰＲ、ＰＶＣ、ＰＥ等からなる加熱収縮チュ−ブが適用できる。 As the heat shrinkable tube A, a heat shrinkable tube made of silicone rubber, EPR, PVC, PE or the like can be applied.

加熱収縮させる前の拡径した状態の加熱収縮チュ−ブＡを装着したロ−プ１を、適宜外径の円筒体２に、図２に示すように、密接して巻き付け、巻き付けた状態で、加熱収縮チュ−ブＡを加熱収縮させ、ロ−プ１に密着させる。 As shown in FIG. 2, the rope 1 fitted with the heat-shrinkable tube A in an expanded state before being heat-shrinked is appropriately wound and wound around a cylindrical body 2 having an outer diameter as shown in FIG. The heat-shrinkable tube A is heat-shrinked and brought into close contact with the rope 1.

ついで、加熱収縮チュ−ブＡのメモリ−材の凍結温度まで加熱収縮チュ−ブＡを冷却し、図３（ａ）に示すように、円筒体２を除去して、弦巻ばね状部Ｂを形成させる。 Next, the heat-shrinkable tube A is cooled to the freezing temperature of the memory material of the heat-shrinkable tube A, and the cylindrical body 2 is removed as shown in FIG. Let it form.

さらに、図３（ａ）に示すように、弦巻ばね状部Ｂに連通するロ−プ１の一端部に、ペットの首輪等に連結させるための留め金部材３を取付け、他端部にわっぱ状の握り部４を設ける。 Further, as shown in FIG. 3 (a), a clasp member 3 for connecting to a collar of a pet or the like is attached to one end portion of a rope 1 communicating with the string-wound spring-like portion B, and the other end portion. A shaped grip 4 is provided.

なお、図３（ｂ）は、図３（ａ）の弦巻ばね状部Ｂに引っ張り力を加え、引き延ばしたときの一例を示した側面図である。 FIG. 3B is a side view showing an example when a tension force is applied to the string-wound spring-like portion B of FIG.

弦巻ばね状部Ｂは、加熱収縮チュ−ブＡのメモリ−材の凍結温度まで冷却し、弦巻ばね状の形状に凍結させているので、形状記憶性を備えており、弦巻ばね状部Ｂに引っ張り力を加え、図３（ｂ）に示すように、引き延ばしても、引っ張り力を除去すると、図３（ａ）に示すように、元の形状に復帰し、収縮する。 The string-wound spring-shaped part B is cooled to the freezing temperature of the memory material of the heat-shrinkable tube A and frozen in a string-wound spring-like shape. Even if the tensile force is applied and stretched as shown in FIG. 3 (b), if the tensile force is removed, the original shape is restored and contracted as shown in FIG. 3 (a).

したがって、ペットが人から離れると、弦巻ばね状部Ｂが伸び、近づくと、弦巻ばね状部Ｂが縮み、ペットの動きに自動的に対応し、引き綱の弛みが生じないので、人やペットへの絡まり付きを確実に防止できる。 Therefore, when the pet moves away from the person, the string-wound spring-like part B expands, and when the pet approaches, the string-wound spring-like part B contracts and automatically responds to the movement of the pet, so that the tow rope does not loosen. It is possible to surely prevent tangling.

持ち運びや保管の簡便さが要求されるペット用以外の引き綱としての用途にも適用できる。 It can also be applied to use as a draw line other than for pets that require ease of carrying and storage.
