Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a fire hose.

[Prior Art] Conventionally, a fire hose is wound around a single roll or a double roll when it is loaded on a fire truck or stored in a fire hydrant box. It had a problem that the condition would collapse and it would be messy.

In order to remedy this drawback, conventionally, the width is 4 cm and the length is 10 cm.
There was a means to stop the outer circumference and the inside with a hairpin-shaped clip of about cm size, and to stop the wound hose with a binding band.

[Problems to be Solved by the Invention] With the conventional clip system or binding band system, it is time-consuming to release these collapse prevention measures in handling emergency fire hoses, which is an urgent matter. It has a drawback that it is easy to lose, and since it is separated from the fire hose, it is very easy to lose it at the fire site.

The present invention was made for the purpose of developing a fire hose having a collapse preventing action without the above-mentioned problems, and stably holds the wound state during double winding and single winding, and handles it. The purpose is to provide a fire hose that requires almost no effort and has a collapse prevention mechanism integrated with the fire hose so that there is no risk of loss.

[Means for Solving the Problems] As a result of various studies for achieving the above-mentioned object, a woven tape known as a so-called Velcro tape (trademark) is used to form one end of a fire hose. It has been found that very good results can be obtained by fixing the female part of the woven tape near the female metal fitting and movably attaching the male part of the woven tape to the hose part inside the woven tape. .

That is, according to the present invention, the female part of the woven tape is bonded and fixed in a ring shape to the near end of the hose near the female metal fitting of the fire hose, and when the fire hose is wound with the female metal fitting as the outer end, the hose is closed. The gist of a fire hose is characterized in that a male part of a woven tape which separates from and contacts the female part is attached in a ring shape capable of moving and adjusting to a distal end part of the hose which is in contact with the end part.

The present invention will be described with reference to the drawings by citing an embodiment.

FIG. 1 is a partial plan view of the vicinity of the end of the fire hose of the present invention.

As shown in this figure, the present invention has a woven tape female portion (3) bonded and fixed in a ring shape to the near end portion (a) of the female metal fitting (2) forming one end of the fire hose (1), and then the hose. The woven tape male portion (4) is attached to the distal end portion (b) in a ring shape so as to be movable and adjusted.

In the present invention, the hose proximal end (a) means a female metal fitting (2).
It means that the distance is about 20 cm from the position 3 to 5 cm away from the ring (5) provided following the female metal fitting (2). The hose far end (b) is used as a term corresponding to the hose near end (a), and when the fire hose (1) is wound with the female fitting (2) as the outer end. In addition, it means a position in contact with the near end portion (a) of the hose, and usually indicates a distance of about 120 to 180 cm from the female metal fitting (2).

The reason why the distance between the distal ends of the hose (b) has a considerable interval width is, as will be described later, that the fire hose (1) is misaligned due to double winding and single winding, and is further dried. This is because the winding state changes and the position of the distal end portion (b) of the hose changes depending on the time and the case where the hose is inflated.

Therefore, the woven tape female portion (3) attached to the near end portion (a) of the hose is adhesively fixed, but the woven tape male portion (4) provided at the far end portion of the hose (4) is loosely inserted. It is attached in a ring shape and its movement can be adjusted.

In FIG. 1, the woven tape male portion (4) is shown as being divided into two pieces. It is easy to move and convenient.

In the present invention, the length of the woven tape female portion (3) is 10 to 10.
About 25 cm is preferable, and it is attached in a ring around the fire hose (1). That is, the woven tape female portion (3) is formed into a tubular shape having a length of 10 to 25 cm having an inner diameter substantially the same as the outer diameter of the fire hose (1), and the near end portion of the hose (for example, double-sided adhesive tape or other adhesive is used. a)
It can be fixed by adhesion.

The length of the woven tape male part (4) is slightly longer than that of the above woven tape female part (3).
It doesn't have to be moved even if it is slightly misaligned,
Even if you move it, the movement distance is short,
Therefore, a suitable length is usually about 15 to 30 cm. In other words, 3 ~ 1 than the outer diameter of the fire hose (1)
It has a cylindrical shape with an inner diameter of about 0 mm and its length is 1
The woven tape male portion (4) having a size of 5 to 30 cm may be loosely inserted into the hose distal end portion (b) with or without being divided into a plurality of pieces.

The woven tape in the present invention is known as a so-called "Magic Tape (trademark)", and examples thereof include those sold by Nippon Velcro Co., Ltd. as "Magic Tape Velcro (trademark)". The female portion (3) is woven so that the loop-shaped piles are densely erected, while the male portion (4) is densely erected with hook-shaped piles. The female part (3) and the male part (4) can be separated and contacted with each other.

[Operation] The present invention has the above-mentioned configuration. Next, the handling method will be described.

FIG. 2 is a schematic front view showing a wound state when the fire hose of the present invention is double wound.

FIG. 3 is a schematic front view showing a wound state when the fire hose of the present invention is wound in a single winding.

As shown in these figures, the fire hose (1) may be folded near the center to be double wound, or may be single wound to be wound around the male metal fitting (6). In either case Is also wound with the female metal fitting (2) as the outer end.

In the fire hose of the present invention, the woven tape female portion (3) is fixed to the near end of the hose near the female metal fitting (2), and the woven tape male portion (4) is attached to the far end of the hose which is inside only once. ) Is attached so that its movement can be adjusted, so that when the winding is completed, the female part (3) and the male part (4) of the woven tape are brought into contact with each other by simply pressing the near end of the hose. The wound state is maintained stably.

In this case, although there is some deviation in the binding position between the double winding and the single winding, the male part (4) can be moved and adjusted, so that the male part (4) can be adjusted to fit the female part (3). The position of) should be adjusted. Further, the binding position may be displaced depending on whether the hose is dry or wet, but it goes without saying that the hose may be adjusted in the same manner.

In the present invention, the female part (3) is fixed to the near end part of the hose. When the male part (4) is fixed to this position, it is easy to get caught in the work gloves when carrying it by hand, and it becomes difficult to handle. This is because the number of times the tip end is stepped on is large and there is a high risk of the hook pile being crushed in the male part (4), so these problems do not occur in the female part (3).

The fire hose of the present invention does not require any trouble when unwinding the wound state, and it suffices to unwind as before. It does not hinder emergency fire-fighting activities at all, and the woven tape is used for fire-fighting. Because it is integrated with the hose, it cannot be lost.

Further, in the present invention, since the female part (3) and the male part (4) of the woven tape are attached in a ring shape, that is, around the entire circumference, the hose may be folded at any position, and the hose may be wound left or right. It doesn't matter which winding method is used, that is, the front and back sides are reversed.

The fire hose of the present invention may be a product having this collapse prevention structure from the beginning, or the hose of the present invention may be attached to a conventional hose.

[Effects of the Invention] The effects of the present invention are listed below.

(B) Not only when the fire hydrant box is stored, but also when loaded in a fire engine and vibrating violently, this fire hose does not become messy because the male fittings fall off, and the winding condition is kept stable. It is a thing.

(B) It is a fire hose that can be easily carried and delivered smoothly even when the female metal fitting is not pressed during use.

(C) When using this fire hose to unwind and extend / extend it, the conventional operation method is sufficient, and it is easy to handle in an emergency without any trouble.

(D) Since the means for preventing the collapse of the winding is integrated with the fire hose, there is no risk of loss.

(E) Double winding, single winding, dry, wet, etc. can be easily dealt with even when the winding conditions change, and the collapse prevention effect can be obtained by simply pressing the winding when the winding is completed.

(F) It is possible to achieve collapse prevention of winding at a low price, and it can be used for hoses of any diameter.

As described above, the fire hose of the present invention has various excellent effects and is extremely useful in fire fighting activities.
