Abstract

<P>PROBLEM TO BE SOLVED: To provide a hose with excellent elasticity, which prevents a sound absorber from coming off from an inner wall, even if an impact, caused by a great tensile force etc., is applied to the hose. <P>SOLUTION: In this sound absorbing cleaner hose 1, rigid reinforcing elements 12a and 12b are spirally wound around and annexed to an inner peripheral surface 15 of a hose wall 11 of a soft synthetic resin; a sound absorbing material 13 is spirally arranged in a gap adjacent to the reinforcing elements 12a and 12b; and a nonwoven fabric tape 14 is spirally wounded around the inner surface of the material 13. Preferably, a rigid synthetic resin, which can be welded to and integrated with the hose wall 11 made of the soft synthetic resin, is used as the reinforcing elements 12a and 12b. For example, a belt-like element such as an open-cell foamed resin tape and felt is used as the material 13 and can be simply arranged in a spiral shape in the gap, adjacent to the reinforcing elements 12a and 12b, in an unbonded state. <P>COPYRIGHT: (C)2004,JPO

【0001】
【発明の属する技術分野】
本発明は、例えば一般家庭で使用されるクリーナーホース、特に、ホースの壁面に吸音体を備えたクリーナーホースに関するものである。
【0002】
【従来の技術】
従来、吸音性のクリーナーホースは、可撓性を持たせるためホース壁が薄膜状の可撓部材から形成されていた。しかしながら、薄膜状の可撓部材から形成されたホース壁は、電気掃除機内を通過する吸気風により発生する風切り音や吸気音がホース壁外へ漏れてしまう問題があった。この問題を解決するために、特開平4−28324号公報ではホースの内表面に螺旋状に配設した芯材間に静音材を埋設した電気掃除機用ホースが記載されている。
【0003】
【発明が解決しようとする課題】
しかしながら、上記電気掃除機用ホースは内周面に形成された静音材が芯材間に埋設されているため伸縮性が悪く、また、強い引っ張りなどによる衝撃から静音材が内表面から剥れる恐れがある。
【0004】
本発明は、上記問題に鑑み、強い引っ張りなどによる衝撃がホースに加わったとしても、吸音体が内壁から剥れることがない伸縮性に優れたホースを提供することを課題とするものである。
【0005】
【課題を解決するための手段】
本発明は、上記問題に鑑み、軟質合成樹脂からなるホース壁と、前記ホース壁の内周面に螺旋状に添着した2本の硬質補強体と、前記2本の硬質補強体の隣接する間隙に螺旋状に配設した吸音材及び前記吸音材の内面に螺旋状に捲回して吸音材を保持する通気性テープとで構成したものであり(請求項1)、また、硬質合成樹脂からなる硬質補強体がホース壁に溶着され(請求項2)、不織布からなる通気性テープを吸音材の両側に配置した2本の硬質補強体の内面に固着している(請求項3)。さらに、2本の硬質補強体の隣接する間隙に吸音材及び通気性テープを配設したピッチと、吸音材及び通気性テープを配設していないピッチとを設けることもでき(請求項4)、吸音材及び通気性テープを配設したピッチと、配設していないピッチとを1ピッチ毎に交互に設けることもできる(請求項5)。
【0006】
【発明の実施の形態】
以下本発明の吸音性クリーナーホースの実施形態について、添付図面を参照して説明する。
【0007】
図1は本発明に係る一実施例を示す吸音性クリーナーホース1の一部縦断側面図であり、吸音性クリーナーホース1は、軟質合成樹脂からなるホース壁11の内周面15に硬質補強体12a、12bが螺旋状に捲回添着されており、硬質補強体12a、12bの隣接する間隙に吸音材13を螺旋状に配設し、さらに、吸音材13の内面に不織布テープ14を螺旋状に捲回して構成されている。硬質補強体12a、12bとしては、硬質合成樹脂が好ましく、軟質合成樹脂製のホース壁11に溶着一体化させることができる。また、吸音材13の例としては、連続気泡の発泡樹脂テープ、フェルト等の帯状体が挙げられ、非着状態で単に硬質補強体12a、12bの隣接する間隙に螺旋状に配設させることができる。
【0008】

【0015】
請求項3の発明では、通気性テープを吸音材の両側に隣接する硬質補強体の内面に固着することで吸音材をホース内壁や補強体へ接着や溶着などの固着手段を必要とすることなく容易に配設できる吸音性クリーナーホースを得ることができる。
【0016】
請求項4の発明では、吸音材及び通気性テープを配置していないピッチ部が通気性テープによる伸縮制限を受けずに、ホース壁自体の豊かな伸縮性により、ホースの伸縮性に優れた吸音性クリーナーホースを得ることができる。
【0017】
請求項5の発明では、通気性テープを1ピッチ毎に形成することにより、強い引張りが生じても前記通気性テープを配置していない部分が衝撃吸収部となり、通気性テープに直接衝撃力が加わらず通気性テープの破損を防ぐ吸音性クリーナーホースを得ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cleaner hose used, for example, in ordinary households, and more particularly to a cleaner hose having a sound absorber on a wall surface of the hose.
[0002]
[Prior art]
Conventionally, in a sound-absorbing cleaner hose, a hose wall is formed of a thin-film flexible member in order to have flexibility. However, the hose wall formed of the thin film-shaped flexible member has a problem that wind noise and intake noise generated by the intake air passing through the vacuum cleaner leak out of the hose wall. To solve this problem, Japanese Unexamined Patent Publication No. 4-28324 describes a vacuum cleaner hose in which a silent material is embedded between cores spirally arranged on the inner surface of the hose.
[0003]
[Problems to be solved by the invention]
However, the vacuum cleaner hose described above has poor elasticity because the silent material formed on the inner peripheral surface is embedded between the core materials, and the silent material may be peeled off from the inner surface by an impact due to strong pulling or the like. There is.
[0004]
In view of the above problems, an object of the present invention is to provide a hose having excellent elasticity in which a sound absorbing body does not peel off from an inner wall even when an impact due to strong pull or the like is applied to the hose.
[0005]
[Means for Solving the Problems]
In view of the above problems, the present invention provides a hose wall made of a soft synthetic resin, two hard reinforcements spirally attached to an inner peripheral surface of the hose wall, and an adjacent gap between the two hard reinforcements. And a breathable tape spirally wound around the inner surface of the sound absorbing material to hold the sound absorbing material (claim 1), and made of a hard synthetic resin. The hard reinforcement is welded to the hose wall (Claim 2), and a breathable tape made of non-woven fabric is fixed to the inner surfaces of the two rigid reinforcements arranged on both sides of the sound absorbing material (Claim 3). Further, a pitch in which the sound absorbing material and the air permeable tape are provided and a pitch in which the sound absorbing material and the air permeable tape are not provided may be provided in a gap adjacent to the two rigid reinforcements. The pitch at which the sound-absorbing material and the air-permeable tape are provided and the pitch at which the sound-absorbing material and the air-permeable tape are not provided can be alternately provided for each pitch.
[0006]

[0010]
FIG. 4 is an enlarged partial view of the sound-absorbing cleaner hose 1 shown in FIG. 3, in which hard reinforcements 12a and 12b are welded to the inner peripheral surface 15 of the hose wall 11 of the sound-absorbing cleaner hose 1 and spirally wound. A pitch A in which a sound absorbing material 13 disposed in a gap adjacent to the hard reinforcements 12a and 12b and a nonwoven fabric tape 14 welded to the inner surfaces of the rigid reinforcements 12a and 12b holding the sound absorbing material 13 are disposed. And pitches B in which the sound absorbing material 13 and the nonwoven fabric tape 14 are not provided are alternately provided for each pitch.
[0011]
The present invention is not limited to the embodiment, and the fixing of the reinforcing member is not limited to welding, but may be fixed to the inner wall using an adhesive. Further, the breathable tape is not limited to a nonwoven fabric tape, but may be a cloth.
[0012]
【The invention's effect】
The present invention is configured as described above, and has the following effects.
[0013]
According to the first aspect of the present invention, the breathable tape retains the sound absorbing material sandwiched between the hose wall and the hard reinforcing members on both sides from the inner surface side while maintaining the sound absorbing properties of the sound absorbing material. Thus, it is possible to obtain a sound-absorbing cleaner hose that does not have a possibility of falling.
[0014]
According to the second aspect of the present invention, the hardening member made of the hard synthetic resin is welded to the hose wall, so that the reinforcing member does not peel off from the hose wall even if an impact is directly transmitted to the hose by forcible pulling. You can get a hose.
[0015]
According to the third aspect of the present invention, the sound-absorbing material is fixed to the inner surface of the hard reinforcing member adjacent to both sides of the sound-absorbing material, so that the sound-absorbing material is not required to be fixed to the inner wall of the hose or the reinforcing member by welding or welding. A sound absorbing cleaner hose that can be easily arranged can be obtained.
[0016]
According to the fourth aspect of the present invention, the sound absorbing material and the sound-absorbing tape are not provided with the pitch portion, which is not limited by the expansion and contraction by the air-permeable tape. A clean cleaner hose can be obtained.
[0017]
According to the fifth aspect of the present invention, by forming the air permeable tape at every pitch, the portion where the air permeable tape is not disposed becomes the shock absorbing portion even if strong tension occurs, and the impact force is directly applied to the air permeable tape. It is possible to obtain a sound-absorbing cleaner hose that prevents breakage of the breathable tape without being added.
