Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a support device for a hose reel for a fire hydrant.

[Conventional technology]

In a conventional fire hydrant, a hose with a lining on the inner surface of a tubular woven fabric is flattened and folded in a zigzag shape,
It is generally stored in a fire hydrant box. But,
The flat and zigzag-shaped hose cannot pass water until it is taken out of the fire hydrant box over its entire length.

Therefore, like a rubber hose, a hose that normally holds a circular cross section is stored in a fire hydrant box in a state wound on a reel.
A support device for a hose reel for a fire hydrant is being studied that allows water to pass through as it is and also allows the hose to be pulled out at any angle from the reel.

An example thereof is shown in FIG. A hose reel around which a hose is wound is rotatably supported by a reel support tool, and the reel support tool is suspended horizontally by a reel suspension tool.
The reel hanger is slidably inserted into a pipe-shaped support, and is temporarily rotatably attached to the inner surface of the fire hydrant box once on the pipe-shaped support. When extinguishing a fire, rotate the pipe-shaped support tool forward and move the reel suspension to the tip of the pipe-shaped support tool, and pull out the hose wound on the hose reel in the required direction (for example, 55-51245 and Japanese Utility Model Publication No. 52-4
799).

Another example is shown in FIG. The door of the fire hydrant box has a hinge at the lower end, and a cushion cylinder between the door and the side surface of the fire hydrant box allows the door to open smoothly on the passage. A hose reel around which a hose is wound is rotatably supported behind the door of this fire hydrant box. When extinguishing a fire, open the door and pull out the hose wound on the hose reel in the required direction (see, for example, Jitsuko Sho 52-41).
279).

[Problems to be solved by the device]

Among those described in the prior art, the one shown in FIG. 8 has a two-step operation of rotating the pipe-shaped support member forward and moving the reel suspension to the tip of the pipe-shaped support device when extinguishing a fire. It is necessary and has a problem that it takes time to operate in an emergency. In addition, since the pipe-shaped support freely rotates in the horizontal direction, the hose reel may unnecessarily project onto the passage.

In addition, although the one shown in FIG. 9 is easy to operate, it has a problem that it occupies an aisle surface because the door opens onto the aisle, which hinders evacuation and fire extinguishing. In particular, when installing in a corridor of a nursing home or a hospital, it is a fatal problem that the hose reel projects forward from the fire hydrant box.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to support a hose reel for a fire hydrant that is easy to operate and has a minimum protrusion to the front surface. It is intended to provide a device.

[Means for solving the problem]

In order to achieve the above object, a support device for a hose reel for a fire hydrant according to the present invention comprises a hose reel around which a hose is wound, a reel supporter that rotatably supports the hose reel, and a reel supporter that is horizontally rotatable. A fire hydrant hose that is equipped with a reel hanger that is hung from the fire hydrant and a fire hydrant box that houses the hose reel, and a support that is provided between the fire hydrant box and the reel hanger to support the hose reel out of the fire hydrant box when the fire is extinguished. In the reel support device,
The support is a support frame that passes between the side surface of the fire hydrant box and the outer circumference of the hose reel. The reel is mounted so that it can be rotated back and forth so that it does not interfere with the fire hydrant box.

In the device for supporting a hose reel for a fire hydrant, it is desirable that the horizontal center of rotation of the reel suspension is eccentric in the width direction of the hose reel.

[Action]

The support between the fire hydrant box and the reel hanger is a support frame that passes between the side surface of the fire hydrant box and the outer periphery of the hose reel, and the upper end of the support frame is attached to the reel hanger so as to be rotatable back and forth. Since the lower end of the hose is attached to the lower part of the fire hydrant box so that the hose reel can rotate back and forth within a range that does not interfere with the fire hydrant box, the hose does not hit the support frame, With a single operation of moving (tilting to the front), the hose reel hung by a horizontally rotatable reel suspension will come out to the front as much as necessary.

In the device for supporting the hose reel for fire hydrant, since the horizontal center of rotation of the reel suspender is eccentric in the width direction of the hose reel, as shown in FIGS. 7 (a) and 7 (b), When pulling out the hose in the direction in which the box door is open, the hose reel extends to the point where it does not hit the door, but when pulling out the hose in the direction opposite to the door, the hose reel goes inside.

A fire extinguishing nozzle 15 capable of opening and closing and adjusting the flow rate is attached to the tip of the hose 14, and the other end of the hose 14 (inside the hose reel 1) is connected to a water supply port. The hose is generally a thick rubber hose that is rigid and does not become flat so that water can pass through the hose reel.
A fire hose that can be flatly folded can also be used by making it possible to reduce the diameter of the winding bed inward (for example, an elastic cylindrical winding bed cut at one place in the longitudinal direction).

The reel support tool 2 rotatably supports the hollow shaft 12 of the hose reel, extends upward on the back surface of the hose reel 1, and
It reaches an eccentric position in the back surface direction (toward the back surface in the width direction of the hose reel) directly above the hose reel 1 and is hung by the reel hanger 3 so as to be horizontally rotatable. Details of the reel support tool 2 are shown in FIG.
This will be described with reference to the drawing and FIG. 4 which is a BB cross section. In FIG. 3, a horizontal shaft 21 of the reel support is rotatably inserted into the hollow shaft 12 of the hose reel, and a cap plate 22 for retaining is bolted to the tip thereof. The horizontal shaft 12 is provided with a water supply hole 23 having a closed end and a side surface hole 24 on the inner peripheral surface, and water is supplied to the hose 14 connected by a water supply port 16 provided on the hollow shaft 12 of the hose reel.
