びサクシヨンホースとして兼用できる補強用の鋼
線と布とがゴム中に埋設されたホースに関する。[Detailed Description of the Invention] The present invention relates to a hose in which reinforcing steel wire and cloth are embedded in rubber and can be used as a delivery and suction hose for lorries, ships, etc.
このゴムホースを湾曲したとき、湾曲部の中央
で鋼線に最も大きな抗力が生ずるが、鋼線が布と

れを生じ補強骨格としての機能を失なつてしま
う。このためにこの種ホースでは鋼線と補強布と
が完全に接着されている。 When this rubber hose is bent, the largest drag force is generated on the steel wire at the center of the bend, but if the steel wire is not bonded to the cloth, when impact pressure is applied inside the hose, Stress concentrates and the helical pitch of the steel wire partially stretches, causing the hose to become constricted and lose its function as a reinforcing skeleton. For this reason, in this type of hose, the steel wire and reinforcing fabric are completely bonded.
この種ホースは用途上長さが大きく、狭い場所
で用いられることが多いので、運搬取扱上、柔軟
で屈曲性のよいものが望まれているが、補強のた
めにゴム中に埋設した布と鋼線とが接着されてい
るために硬く曲りにくいものであつた。 This type of hose has a long length and is often used in narrow spaces, so it is desired to be flexible and flexible for transportation and handling. Because it was bonded to steel wire, it was hard and difficult to bend.
本考案は従来よりも曲げ易いこの種ゴムホース
を提供することを目的とする。 The object of the present invention is to provide a rubber hose of this type that is easier to bend than conventional rubber hoses.
本考案は、この目的を達するために、ゴム中に

ピツチの間に二重らせん状に布と非接着の状態で
配置したものである。 In order to achieve this purpose, the present invention is designed to install a steel wire between an upper fabric layer and a lower fabric layer, which are bonded and embedded in rubber for reinforcing each other. The other steel wires are placed in a double helix shape between the pitches of the bonded steel wires without being bonded to the cloth.

である。 The figure is a sectional view showing the structure of an embodiment of the rubber hose according to the present invention, in which 1 is an inner rubber layer, 2 is a lower fabric layer bonded to the outer periphery of the inner rubber layer 1, and 3 is bonded to the outer periphery of the lower fabric layer. 4 is an outer rubber layer adhered to the outer periphery of the upper fabric layer 3, and 5 is the lower fabric layer 2 and the upper fabric layer 3.
6 is the pitch of the fixed steel wire 5 between the lower fabric layer 2 and the upper fabric layer 3. A movable steel wire is spirally wound around the lower fabric layer 2 and the upper fabric layer 3 in a non-adhesive state at the same pitch as the fixed steel wire 5 in the center.

７倍で7.5Kgｆ、約４倍強で折れを生じた。 The inner rubber layer is made of nitrile rubber with a thickness of 2.5 mm, and around the outer periphery, a polyester canvas with a thickness of 0.7 mm and a width of 131 mm is topped with nitrile rubber on both sides with a thickness of 0.3 to 0.5 mm. A steel wire with a diameter of 2.5 mm and rubber glue applied all around the outer circumference of the lower fabric layer is wound spirally with a pitch of 23 mm, and a steel wire with the same diameter without rubber glue Wrap the wire in a double spiral around the center of the pitch of the previously wound steel wire, then apply the same fabric as the lower fabric layer on top of this in a spiral shape as an upper fabric layer, and then wrap around the outer periphery.
Chloroprene rubber is applied as an outer rubber layer to a thickness of 1.5 to 2 mm, inner diameter is 65 mm, and normal pressure is -1 to 4 kg/
Formed cm2 oil resistant lorry hose. Separately, a comparison hose was made with the same structure as above, except that only one steel wire was coated with rubber glue of 2.5 mm in diameter at a pitch of 15 mm, and a bending test was conducted.
In the proposed hose, the force required to bend the hose to an inner diameter that is approximately 7 times the inner diameter was 5.5 Kgf, or 12 Kgf, which is approximately 4 times the inner diameter. Creases occurred at a strength of just over 4 times.
このように本考案ホースが従来ホースよりもよ
く曲るのは、可動鋼線が上布層と下布層との間で
自由に動くことができるためと考えられる。固定
鋼線５と可動鋼線６とは線径を異ならしめても良
い。 The reason why the hose of the present invention bends better than the conventional hose is thought to be because the movable steel wire can freely move between the upper fabric layer and the lower fabric layer. The fixed steel wire 5 and the movable steel wire 6 may have different wire diameters.
本案ホースによれば従来より曲りのよいゴムホ
ースを安価に提供できる。 According to the hose of the present invention, a rubber hose with better bending than the conventional hose can be provided at a lower cost.
