BACKGROUND OF THE INVENTION When a fire hose is hooked on a protrusion or the like during use, damage such as pinholes often occurs on the surface and inner rubber lining of the hose. Conventionally, a method for repairing a damaged portion of a hose in this manner is to apply a repair patch to the damaged portion from the outer wall of the hose to cover and repair the damaged portion.

効な方法ではない。 However, hoses repaired using the conventional method described above are not fully satisfactory in terms of water leakage prevention effect; for example, when used at low water pressure, there is no problem, but when water pressure increases, the repaired part inevitably leaks. This method has the problem of water leakage, and is not necessarily an effective method.

種々の制限があり、簡易かつ迅速なホース修理を
行うためのものとは言い難い。 Furthermore, a method of repairing a damaged part of a hose by pasting a repair patch from the inner wall side of the hose and a repair tool for that purpose have also been proposed (Utility Model Application Publication No. 19190/1983 and Japanese Patent Publication No. 1983/1983). 7726). However, these conventional repair jigs have relatively complex structures in order to perform repairs from inside the hose, and there are various limitations regarding repair operations. It's hard to say.

を具備してなることを特徴とするものである。 In order to achieve the above object, a hose repair tool according to the present invention is a hose repair tool for repairing a hose by inserting it into the inside of a hose and pasting a repair patch from inside the hose to a damaged part of the hose. And,
A cylindrical holding cover with one side open; a shaft rod that penetrates a shaft hole provided in the center of the upper lid of the holding cover and is movable up and down; a pressure contact plate for holding a repair patch provided at the tip; a pressure pad provided at the tip of the shaft rod on the outside of the holding cover; The holding cover is characterized by comprising a biasing means for biasing the holding cover toward the holding cover, and an elongated insertion bar connected to the outer side of the holding cover.
以下、本発明を添付図面に基いて具体的に説明

修理用パツチ５を保持する。 FIG. 1 is a sectional view of one embodiment of a repair tool used in the hose repair method according to the present invention. That is, the hose repair tool of the present invention has a long insertion bar 1.
A pressure member A is attached to the tip of the holder. The pressure contact member A has a pressure contact plate 3 that is disposed so as to be movable up and down along a shaft hole provided in the center of the upper lid portion of the cylindrical holding cover 2, and this pressure contact plate 3 is moved by a spring 4. It is biased toward the upper lid portion of the holding cover 2. The press plate 3 also holds a repair patch 5, such as a rubber patch.
次に、上記ホース修理具を用いて実際に消防用
ゴム引きホース（内面がゴムでライニングされた

法について説明する。 Next, a specific method of repairing pinholes actually formed in a rubberized fire hose (a hose whose inner surface is lined with rubber) using the hose repair tool will be described.
本発明の修理方法においては、まず必要に応じ
てホース内面のピンホール付近の水分および汚れ
を適当な清掃具にてきれいに拭き取りシンナー等
でその部分を清掃する。 In the repair method of the present invention, first, if necessary, moisture and dirt near the pinhole on the inner surface of the hose are thoroughly wiped off using an appropriate cleaning tool, and the area is cleaned with thinner or the like.
次いで、第２図に示すように、ホース修理具を
ホース２０内に挿入し、ピンホールのある部分に
配置し、適当な固定器具Ｂによつて挟持し固定す

ホースの外部から注入したのち、ロツクピン２１
を抜去して押圧パツド６を押し下げ接着剤を均等
に押し広げてピンホール周辺に接着剤層２３を形
成する（第３図参照）。 Next, as shown in FIG. 2, the hose repair tool is inserted into the hose 20, placed in the area with the pinhole, and clamped and fixed with a suitable fixing device B. In this case, in order to prevent the pressure contact plate inside the holding cover from falling, use the U-shaped locking pin (with string) 2.
1 is sandwiched between a pressing pad (pressing plate) 6 and a holding cover 2. In this state, as shown,
After injecting an appropriate amount (for example, about 1 to 2 c.c.) of adhesive such as rubber glue from the outside of the hose with the syringe 22 through the pinhole, lock pin 21
is removed and the pressing pad 6 is pushed down to spread the adhesive evenly to form an adhesive layer 23 around the pinhole (see FIG. 3).

剤層に仮貼着させる。 Next, the repair patch 5 is attached to the pressure contact plate 3 of the hose repair tool using a slightly adhesive adhesive such as water glue, and the lock pin 21 is inserted between the pressure pad 6 and the holding cover 2. It is inserted into the hose again and placed on the adhesive layer 23 as shown in FIG. Next, the lock pin 21 is removed and the pressure pad 6 is pushed down to temporarily attach the patch 5 to the adhesive layer.
次に、第５図に示すように、圧着プレートＣを
パツチ貼着位置まで挿入し、固定機具Ｂによつて
挟持し加圧してパツチ５を完全に接着させて補修
作業が完了する。 Next, as shown in FIG. 5, the pressure bonding plate C is inserted to the patch attachment position, clamped and pressed by the fixing device B, and the patch 5 is completely adhered to complete the repair work.

れなかつた。Test Example A water pressure test was conducted at a pressure of 16 Km/cm 2 on a fire hose whose pinhole had been repaired as in the above example, and as a result, no water leakage from the repaired portion was observed.
さらに、圧力13Kg／cm2、流量1750／mim、
流速20ｍ／secの条件で放水試験を行なつたが、
まつたく異常は認められなかつた。 Furthermore, the pressure is 13Kg/cm 2 , the flow rate is 1750/mim,
A water spray test was conducted at a flow rate of 20 m/sec, but
No abnormalities were observed.
比較例
ホースの外壁側からパツチを貼着する以外は上
