【０００８】
【発明の実施の形態】
以下、本発明の各実施例を図面に基づいて説明する。
各実施例は、性能が異なる複数の弾性変形可能な管体として、所定長さずつ切断されたホースの見本を夫々陳列し、これらホースの見本を顧客が自由に操作して両ホースの性能を同時に比較テストできるようにしている。
【０００９】
【実施例１】
この実施例は、図１（ａ）（ｂ）に示す如く、性能が異なる複数の弾性変形可能な管体として、例えば特表２００１−５１１２３２号公報に開示されるような内層Ｈ１と外層Ｈ２との間にニット編みされたブレードＨ３を挟み込んで一体化することにより捻れ難くなったホース１と、従来品の捻れ易いホース２とを平行に並べて装置本体Ａに取り付け、これら両ホース１，２を捩れたまま引っ張って夫々の性能が比較テストされる場合を示すものである。
【００１０】
この装置本体Ａには、上記両ホース１，２の一端部１ａ，２ａを移動不能に固定すると共に、他端部１ｂ，２ｂを移動可能な操作部３に連結し、この操作部３の移動により両ホース１，２を同じ量ずつ同時に変位させて比較する。
【００１１】
本実施例では、装置本体Ａに、直線方向へ延びる一対のレール４，４を平行に配設し、これらレール４，４に操作部３としてスライダー３ａを夫々係合させて該レール４，４の軸方向へ往復動自在に支持しており、上記レール４，４の端部に亘って配設された枠体５に、両ホース１，２の一端部１ａ，２ａを移動不能に固定し、これら両ホース１，２を夫々同じ方向へ同角度だけ捻った状態で他端部１ｂ，２ｂを操作部３のスライダー３ａに連結している。
【００１２】
図示例では、上記レール４，４を円筒パイプで構成し、これら円筒パイプが貫通する通孔３ｂ，３ｂを操作部３のスライダー３ａに貫通開穿して摺動可能に挿通させたが、これに限定されず、操作部３を両ホース１，２の軸方向へ往復動自在に支持できれば、上記円筒パイプに代えて角パイプを使うなど、他の構造でも良い。
【００１３】
次に、斯かる管体性能比較表示装置の作動について説明する。
先ず、図１（ａ）に示される如く、捻れ難いホース１と捻れ易いホース２とが同じ条件で捻られた状態において、図１（ｂ）に示される如く、操作部３のスライダー３ａを手動により同じ長さずつ直線移動すれば、これら両ホース１，２が捩れたまま引っ張られる。
【００１４】
それにより、捻れ難いホース１は、その捩れがホース全体に分散するため、途中で折れ曲がらず内部流路１ｃが確保されるのに対し、捻れ易いホース２は、その捩れが一箇所に集中するため、途中で折れ曲がって内部流路２ｃが閉鎖される所謂キンク状態となり、両ホース１，２の引っ張りに対する捩れ性能が同時に現れて比較し易い。
その結果、一つの動作(ワンアクション)のみでホース１の耐捩れ性能が一目瞭然となり、簡単な操作で比較対象のホース１，２の性能を明確に見分けることができる。
【００１５】
特に本実施例の場合には、例えばリールなどに環状に巻き付けられて巻き癖がついたホース１，２をより戻すことなく無理に引き出した状況を想定して比較テストできる。
【００１６】
【実施例２】
この実施例は、図２（ａ）（ｂ）に示す如く、捻れ難いホース１の他端部１ｂと、捻れ易いホース２の他端部２ｂを相互に連係させ、これら両ホース１，２の他端部１ｂ，２ｂに亘って操作部３を連設し、この操作部３を各ホース１，２の周方向へ回転自在に支持すると共に同角度ずつ回転移動させて、これら両ホース１，２を同時に捻る構成が、前記図１に示した実施例とは異なり、それ以外の構成は図１に示した実施例と同じものである。
【００１７】
この場合、両ホース１，２は夫々捻ることなく平行に並べられ、これらの一端部１ａ，２ａを装置本体Ａに移動不能に固定すると共に、他端部１ｂ，２ｂを装置本体Ａに回転自在に支持し、これら他端部１ｂ，２ｂに連設した操作部３の移動により各ホース１，２を夫々の周方向へ同角度ずつ回転移動させる。
【００１８】
図示例では、両ホース１，２の他端部１ｂ，２ｂにパイプ６，６を嵌挿するなど一体的に固着し、これらパイプ６，６を装置本体Ａの端部に配設された支持体７に夫々回転自在に軸支すると共に、両パイプ６，６に亘って例えば環状ワイヤやベルトなどの連係体８で架け渡すことにより一体化し、この両パイプ６，６のどちらか一方に操作部３としてＬ形レバー３ｃを連設している。
【００１９】
なお、図示した構造に限定されず、操作部３の移動により各ホース１，２を夫々の周方向へ同角度ずつ回転移動できれば、他の構造でも良い。
【００２０】
そして、斯かる管体性能比較表示装置の作動について説明する。
先ず、図２（ａ）に示される如く、捻れ難いホース１と捻れ易いホース２とが捻ることなく並べられた状態において、図２（ｂ）に示される如く、操作部３のＬ形レバー３ｃを手動により回転移動すれば、これら両ホース１，２が連係体８を介して夫々の周方向へ同角度ずつ回転され捻られる。
【００２１】
それにより、捻れ難いホース１は、その捩れがホース全体に分散するため、潰れずに内部流路１ｃが確保されるのに対し、捻れ易いホース２は、その捩れに伴って潰れて内部流路２ｃが閉鎖される所謂キンク状態に近い状況となり、両ホース１，２の捻りに対する保形性能が同時に現れて比較し易い。
【００２２】
その結果、図１に示した実施例と同様に、一つの動作(ワンアクション)のみでホース１の耐捩れ性能が一目瞭然となり、簡単な操作で比較対象のホース１，２の性能を明確に見分けることができる。
【００２３】
特に本実施例の場合には、水栓などに接続した状態でホース１，２のみが捻られた状況を想定して比較テストできる。
【００２４】
尚、前示各実施例では、性能が異なる複数の弾性変形可能な管体として、所定長さずつ切断されたホースの見本を顧客が自由に操作して両ホースの性能を同時に比較テストする場合を示したが、これに限定されず、ホースの見本に代えてそれ以外の管体を使用しても良い。
【００２５】
更に、性能が異なる複数の弾性変形可能な管体として、捻れ難いホース１と捻れ易いホース２を比較する場合を示したが、これに限定されず、捩れ以外の性能が異なる管体を３本以上、同時に比較するように使用しても良い。
【００２６】
【発明の効果】
以上説明したように、本発明のうち請求項１記載の発明は、性能が異なる複数の管体１，２を並べ、これら管体１，２の移動可能な他端部１ｂ，２ｂを、操作部３の移動で同じ量ずつ同時に変位させることにより、各管体１，２の性能が同時に現れて比較し易いので、簡単な操作で比較対象の管体の性能を明確に見分けることができる。
従って、性能の優位性を消費者に伝えて、効率的に販売促進できる。
【００２７】
請求項２の発明は、請求項１の発明の効果に加えて、管体１，２が同じ条件で捻られた状態において、操作部３を同じ長さずつ直線移動させて、管体１，２を捩れたまま引っ張ることにより、管体１，２の引っ張りに対する捩れ性能が同時に現れて比較し易いので、環状に巻き付けられて巻き癖がついた管体１，２をより戻すことなく無理に引き出した状況を想定して比較テストすることができる。
【００２８】
請求項３の発明は、請求項１の発明の効果に加えて、管体１，２が捻ることなく並べられた状態において、操作部３を各管体１，２の周方向へ同角度ずつ回転移動させることにより、管体１，２の捻りに対する保形性能が同時に現れて比較し易いので、水栓などに接続した状態で管体１，２のみが捻られた状況を想定して比較テストできる。

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
Each embodiment displays a sample of hose cut by a predetermined length as a plurality of elastically deformable tubes having different performances, and the customer freely operates these hose samples to improve the performance of both hoses. A comparison test is possible at the same time.
[0009]
[Example 1]
In this embodiment, as shown in FIGS. 1A and 1B, as a plurality of elastically deformable tubes having different performances, for example, an inner layer H1 and an outer layer H2 as disclosed in JP-T-2001-511232, A hose 1 that has become difficult to twist by sandwiching a knit braided blade H3 between them and a hose 2 that is easily twisted in parallel are attached to the apparatus main body A in parallel, and both the hoses 1 and 2 are attached. It shows a case where each performance is compared and tested by pulling while twisting.
[0010]
In this apparatus main body A, the one ends 1a and 2a of both the hoses 1 and 2 are fixed so as not to move, and the other ends 1b and 2b are connected to a movable operation section 3 to move the operation section 3. The two hoses 1 and 2 are simultaneously displaced by the same amount and compared.
[0011]
In the present embodiment, a pair of rails 4, 4 extending in the linear direction are arranged in parallel on the apparatus main body A, and a slider 3 a is engaged with each of the rails 4, 4 as the operation unit 3, and the rails 4, 4 are respectively engaged. The end portions 1a and 2a of both hoses 1 and 2 are fixed to the frame 5 disposed over the ends of the rails 4 and 4 so as not to move. The other ends 1b and 2b are connected to the slider 3a of the operation unit 3 in a state where both the hoses 1 and 2 are twisted in the same direction by the same angle.
[0012]
In the illustrated example, the rails 4 and 4 are formed of cylindrical pipes, and the through holes 3b and 3b through which the cylindrical pipes penetrate are pierced through the slider 3a of the operation unit 3, and are slidably inserted. The structure is not limited to the above, and other structures such as a square pipe may be used instead of the cylindrical pipe as long as the operation unit 3 can be reciprocally supported in the axial direction of both the hoses 1 and 2.
[0013]
Next, the operation of such a tube performance comparison display device will be described.
First, as shown in FIG. 1A, when the hose 1 that is difficult to twist and the hose 2 that is easy to twist are twisted under the same conditions, the slider 3a of the operation unit 3 is manually moved as shown in FIG. If both the hoses 1 and 2 are linearly moved by the same length, the two hoses 1 and 2 are pulled while being twisted.
[0014]
As a result, the hose 1 that is difficult to twist is dispersed in the entire hose, so that the inner flow path 1c is secured without being bent in the middle, whereas the twist of the hose 2 that is easy to twist is concentrated in one place. Therefore, the inner flow path 2c is bent in the middle and becomes a so-called kink state, and the torsional performance with respect to the pulling of both the hoses 1 and 2 appears at the same time and is easy to compare.
As a result, the torsion resistance performance of the hose 1 becomes obvious at a glance with only one operation (one action), and the performance of the comparison hoses 1 and 2 can be clearly distinguished by a simple operation.
[0015]
In particular, in the case of the present embodiment, for example, a comparative test can be performed on the assumption that the hoses 1 and 2 wound in a ring on a reel or the like and having a curl are forcibly pulled out without returning.
[0016]
[Example 2]
In this embodiment, as shown in FIGS. 2 (a) and 2 (b), the other end 1b of the hose 1 which is difficult to twist and the other end 2b of the hose 2 which is easy to twist are linked to each other. The operation unit 3 is connected over the other end portions 1b and 2b, and the operation unit 3 is rotatably supported in the circumferential direction of the hoses 1 and 2 and is rotated by the same angle. The configuration for twisting 2 at the same time is different from the embodiment shown in FIG. 1, and the other configuration is the same as the embodiment shown in FIG.
[0017]
In this case, the hoses 1 and 2 are arranged in parallel without twisting, and the one end portions 1a and 2a are fixed to the apparatus main body A so as not to move, and the other end sections 1b and 2b are rotatable to the apparatus main body A. The hoses 1 and 2 are rotated and moved in the respective circumferential directions by the same angle by the movement of the operation unit 3 connected to the other end portions 1b and 2b.
[0018]
In the illustrated example, the pipes 6 and 6 are integrally fixed to the other ends 1b and 2b of both the hoses 1 and 2, and the pipes 6 and 6 are supported at the end of the apparatus main body A. Each of the pipes 6 and 6 is pivotally supported on the body 7 and is integrated by linking the pipes 6 and 6 with a linkage body 8 such as an annular wire or a belt. An L-shaped lever 3c is continuously provided as the portion 3.
[0019]
In addition, it is not limited to the structure shown in figure, The other structure may be sufficient if each hose 1 and 2 can be rotationally moved by the same angle to each circumferential direction by the movement of the operation part 3. FIG.
[0020]
Then, the operation of such a tube performance comparison display device will be described.
First, as shown in FIG. 2 (a), in a state where the hose 1 which is difficult to twist and the hose 2 which is easy to twist are arranged without being twisted, as shown in FIG. If these are manually rotated, these hoses 1 and 2 are rotated by the same angle in the circumferential direction via the linkage 8 and twisted.
[0021]
Thereby, the hose 1 that is difficult to twist is dispersed in the entire hose, so that the internal flow path 1c is secured without being crushed, whereas the hose 2 that is easily twisted is crushed along with the twist and the internal flow path. It becomes a situation close to a so-called kink state in which 2c is closed, and the shape retaining performance against twisting of both the hoses 1 and 2 appears at the same time and is easy to compare.
[0022]
As a result, as in the embodiment shown in FIG. 1, the torsion resistance of the hose 1 becomes obvious at a glance with only one action (one action), and the performance of the comparison hoses 1 and 2 can be clearly distinguished by a simple operation. be able to.
[0023]
In particular, in the case of the present embodiment, a comparative test can be performed on the assumption that only the hoses 1 and 2 are twisted while being connected to a faucet or the like.
[0024]
In each of the preceding examples, as a plurality of elastically deformable tubes having different performances, a customer freely operates a sample of a hose cut by a predetermined length, and simultaneously compares and tests the performance of both hoses. However, the present invention is not limited to this, and other pipe bodies may be used instead of the hose sample.
[0025]
Furthermore, although the case where the hose 1 which is hard to twist and the hose 2 which is easy to twist are compared is shown as a plurality of elastically deformable tubular bodies having different performances, the present invention is not limited to this, and three tubular bodies having different performances other than twisting are shown. As mentioned above, you may use so that it may compare simultaneously.
[0026]
【The invention's effect】

Therefore, the superiority of performance can be communicated to consumers and sales can be promoted efficiently.
[0027]
In addition to the effect of the invention of claim 1, the invention of claim 2 moves the operating portion 3 linearly by the same length while the tubes 1 and 2 are twisted under the same conditions. By twisting 2 while twisting, the twisting performance against the pulling of the tubes 1 and 2 appears at the same time, and it is easy to compare them. Forcibly without returning the tubes 1 and 2 that are wound in an annular shape and have wrinkles A comparative test can be performed assuming the pulled-out situation.
[0028]
