Description

[Detailed Description of the Invention] The present invention relates to a new and extremely convenient hose reel for fire extinguishing equipment (hereinafter simply referred to as a hose reel).

As is well known, hose reels are installed in fire engines, indoor storage boxes, etc., but until now, most hose reels have been of the type where the reel shaft is oriented horizontally and the hose is wound vertically around the reel body. Moreover, the reel body was fixed so that it could not be moved. Therefore, for example, when pulling out the hose C from the hose reel B installed in the storage box A as shown in FIG. As shown in the figure, the angle θ at which the can be pulled out became small, which was quite disadvantageous for firefighting operations where every moment counts. A similar problem also occurred when a hose reel was installed at the rear of a small vehicle such as a light van equipped with a fire extinguishing system.

In view of this problem, the present invention aims to provide a convenient hose reel for a fire extinguishing system that has a very wide hose pull-out angle and can smoothly pull out the hose.

In order to achieve the above object, the present invention is a fire extinguishing device in which a hose reel body, in which a hose communicating with a fire extinguishing agent supply pipe is wound, is attached to a base fixed in a storage area such as a hangar or a car loading platform. In the hose reel, the distal end portion is pulled out of the accommodating portion from the opening of the accommodating portion by pulling a rail material and a handle provided at the distal end portion fitted to the rail material on the base. A slide rail is provided, and the hose reel body is horizontally rotatably mounted on the slide rail via a reel body support frame, so that the hose reel body can be pulled out of the housing section.

Hereinafter, the hose reel of the present invention will be described in detail based on the drawings.

Fig. 2 is a plan view of an embodiment of the hose reel of the present invention, Fig. 3 is a front view of the same embodiment, Fig. 4 is a sectional view taken along the - line in Fig. 2, and Fig. 5 is a state in which the hose reel is pulled out. 1 is a perspective view of the same embodiment.
2 indicates a base, 2 indicates a hose reel body, and 3 indicates a hose wound around the hose reel body.

That is, the base 1 has a pair of U-shaped legs 4,
4, a pair of rail members 5 having a substantially C-shaped cross section,
5 are strung together to form a frame-shaped base having a substantially square plane as shown in FIG. The slide rails 6, 6 are slidably fitted together, and second slide rails 7, 7 having a U-shaped cross section are slidably fitted inside the slide rails 6, 6. Then, plate materials 8, 8 are fixed to the inside of these second slide rails 7, 7, and a rectangular reel body support frame 9 is installed in an upright state between these plate materials 8, 8. A hose reel main body 2 is mounted within a support frame 9 so as to be horizontally rotatable.

The hose reel main body 2 has a pair of circular side plates 11, 11 attached near the end of a hollow shaft 10, and a winding core 11A formed by a plurality of bolts 12 passing through these circular side plates 11, 11. axis 1
0 is vertically oriented, and its both ends penetrate the upper frame portion 13 and lower frame portion 14 of the reel main body support frame 9 and are rotatably supported horizontally. A supply pipe 16 is connected to one end (lower end) of this hollow shaft 10 via a swivel joint 15.

The hose 3 has an injection nozzle 17 at its tip, and the hose winding start end is connected to a connection port (not shown) formed in the hollow shaft 10 of the hose reel body, and is wound horizontally around the hose reel body 2.

In the figure, 18 is a handle for drawing out the hose reel body attached between one end of the plates 8, 8, and 19 is a stopper for stopping the rotation of the hose reel body 2.

Such a hose reel can be placed in a storage box or in the storage area P at the rear of a small vehicle equipped with a fire extinguisher as shown in Figure 6.
It is installed with the base 1 fixed on it, and is used in the following manner. That is, to explain the case of Fig. 6,
First, open the rear door of the small car, hold the handle 18 for pulling out the hose reel body, and pull out the hose reel body 2.
Pull it out of the vehicle as shown by the chain line. At this time, as shown in FIG. 5, the first slide rails 6, 6 protrude from the rail materials 5, 5 of the base 1, and the second slide rails 7, 7 protrude from the first slide rail. The slide stroke becomes larger,
Therefore, the hose reel main body 2 can be sufficiently pulled out to the outside of the vehicle. When the hose reel main body 2 is pulled out in this manner, stoppers 20 and 21 made of spring materials provided on the inner surface of the rail material 5 and the outer surface of the second slide rail 7, as shown in FIG.
are engaged with the front and rear ends of the first slide rail 6, respectively, so the hose reel main body 2 will not be pulled into the vehicle interior without permission. When the hose reel body 2 is pulled out, the supply pipe 16 connecting the extinguishing agent storage tank 22 and the hollow shaft 10 of the hose reel body 2
Since the supply pipe 16 is also drawn out, the supply pipe 16 is bent in advance into an S-shape as shown in FIG.

After the hose reel main body 2 has been drawn out in this way, the stopper 19 is released to allow the hose reel main body 2 to freely rotate horizontally, and the hose 3 is pulled out by holding the injection nozzle 17 at the tip of the hose 3. Press a spray button (not shown) to spray extinguishing agent onto the fire area. in this case,
Since the hose reel main body 2 is pulled out to the outside of the vehicle, the hose 3 can be pulled out within an extremely wide hose pull-out angle θ as shown in FIG.
Moreover, since the hose reel main body 2 is horizontally rotatable, the hose 3 can be drawn out smoothly without hitting the circular side plate 11 of the hose reel main body 2, no matter which direction the hose 3 is drawn out.

As can be understood from the above explanation, the hose reel for fire extinguishing equipment of the present invention allows the hose reel body to be easily and quickly pulled out of the housing by pulling the handle provided at the tip of the slide rail. Moreover, when the hose reel body is pulled out of the storage section, the hose reel body is attached to the slide rail via the reel body support frame so that it can rotate freely horizontally, so the hose can be pulled out over a wide range of hose pull-out angles. In addition, since the slide rail on which the hose reel is attached is fitted to the rail material on the base, the hose can be pulled out smoothly, which is extremely advantageous when fighting fires in a timely manner. It is of extremely high practical value.
