Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting device for a hose reel for fire fighting, which allows the hose reel to be pulled out from and put into the fire hydrant box accurately and quickly.

[0002]

2. Description of the Related Art Conventionally, as a supporting device for a hose reel for fire fighting, as disclosed in, for example, Japanese Utility Model Publication No. 51-48238, the base end of a supporting arm is vertically attached to the upper end of a rear wall in a fire hydrant box. The hose reel is rotatably supported and the hose reel is hung from the tip of this support arm.When not in use, the support arm is suspended and the hose reel is stored in the fire hydrant box. It is known that the hose reel is configured to be pulled out from the storage box to the outside by rotating and projecting it horizontally.

Further, as described in Japanese Utility Model Publication No. 52-4799, the base end of a support arm is horizontally rotatably supported by one end of the inner wall of the upper wall of the storage box. The upper end of the hanger with a hose reel suspended on it is slidably hung in the length direction of the support arm, and when in use, the hanger is moved forward from the storage box while moving the hanger to the tip side of the support arm. There is also known a device configured to pull out the hose reel by projecting the hose reel toward the outside.

[0004]

However, according to the former device, the support arm must be hung and the hose reel must be hung at the lower end of the support arm and stored in the storage box. In addition to requiring a large storage box, it is not only restricted by the installation location, but it also takes time and effort to install it.In addition, when using it, the support arm must be erected from the hanging state to a horizontal state and kept in that state. There is a problem that it takes time to extinguish the fire because it cannot be pulled out.

On the other hand, according to the latter device, as in the former device, one hose reel is pulled out by projecting one support arm forward from the storage box, so that the pulled-out hose reel is used. In order to freely rotate in the hose withdrawal direction without being disturbed by not only the relatively long supporting arm is required, but also the supporting arm has to be arranged above the hose reel. In addition, it is necessary to increase the height of the storage box.In addition, when storing the hose reel in the storage box, when the hose reel is suspended from the tip of the support arm, the hose reel will not open the storage box. Since it cannot be stored by abutting against the end, the suspender must be moved to the center of the support arm in the longitudinal direction.
It takes time to store. Further, even in the stored state, the suspension of the hose reel deviates in the left-right direction of the storage box along the support arm due to vibration, etc., and engages with the hose nozzle supported on the inner surface of the side wall of the box to smoothly pull out. There were problems such as hindrance.

The present invention has been made in view of the above problems, and the storage box can be made compact and the hose reel can be easily and surely stored at a predetermined position of the box. It is an object of the present invention to provide a support device for a hose reel for fire fighting, which can quickly pull out the hose reel from the storage box.

[0007]

In order to achieve the above object, a supporting device for a fire hose reel according to the present invention is arranged such that a base end of a first arm is rotatable in a left-right direction on a front surface of a rear wall plate of a fire hydrant box. The base end of the second arm is connected to the tip of the first arm so as to be bent in the left-right direction, the connection fitting is pivotally supported on the end of the second arm so as to be rotatable left and right, and the fire hydrant box is attached to the connection fitting. It has a structure in which the center portion of the outer surface of one reel frame plate of the hose reel housed inside is rotatably connected.

According to a second aspect of the present invention, the second arm is formed to have a length that is approximately half the length of the first arm, and the base end of the second arm is located above the tip of the first arm. And the base end of the connecting fitting is pivotally attached to the tip of the second arm by means of a pin, and one reel is attached to this connecting fitting. It has a specific structure in which a short tubular member fixed to the central portion of the outer surface of the frame plate is rotatably connected.

Further, the invention described in claim 3 is the first
The arm and the two arms are formed to have substantially the same length and a length equal to or less than the radius of the hose reel.

[0010]

The first arm is rotated by moving the first arm along the rear wall plate of the fire hydrant box and folding the second arm with respect to the first arm in a direction opposite to the rotation direction of the first arm. In the same way as when the fire hydrant box is placed along the rear wall plate, the hose reel in which the center of the outer surface of one reel frame plate is pivotally supported by the tip of the second arm is automatically folded by these arms. It is stored so as to be drawn to a predetermined position in the center of the storage box. In this state, the hose reel is housed so as to cover the folded arms, so that these arms do not appear outside and can be stored neatly and the storage box can be made compact.

When the hose reel is pulled out from the storage box during use, the first arm stands upright from the rear wall plate of the storage box, and the second arm rotates in the extension direction of the first arm. With the length corresponding to the sum of the lengths, the hose reel is projected from the storage box to the outside of the box, and the hose reel pivotally moves in the hose withdrawal direction with respect to the tip end of the second arm, It enables smooth withdrawal.

Further, when pulling out the hose reel from the storage box, the hose reel can be easily pulled out in the extension direction of the first arm and the second arm, and the extension length of both arms allows the hose reel to be extended. Since the hose reel can be projected forward from the storage box,
The hose reel can be pulled out from the storage box to a larger extent than with a single support arm that is restricted in length as in the past, and therefore the hose reel can be moved in the left-right direction relative to the tip of the second arm according to the pulling-out direction of the hose. Even when the storage box is rotated to the above position, the storage box does not come into contact with the open end of the storage box to enable smooth use.

Since the center of rotation on the outer surface of one reel frame plate of the hose reel is rotatably supported by the connecting metal fitting at the tip of the second arm, the hose reel can be rotated in the conventional manner. A frame for suspending and supporting is not required, so not only the structure is simplified but also the hose reel can be supported stably, and there are no obstacles around the hose reel, and the hose winding work is easy and quick. It can be done.

Further, when the hose reel is stored in the storage box, the hose reel is automatically guided to a predetermined position in the storage box while bending in a direction in which the first arm and the second arm fold each other. Can be stored,
Therefore, the storage work can be performed reliably and easily, and
After the storage, the folded arm prevents the hose reel from moving in the left-right direction and can be kept small in a state where it can be quickly pulled out.
