Description

[Detailed Description of the Invention] The present invention relates to a frame that supports fire extinguishing nozzles such as water spray nozzles and air foam nozzles.

The conventional portable monitor itself was disposed between the hose end and the nozzle end, and the radially horizontally projecting legs were fixed.

Therefore, depending on the fire situation, it is necessary to suspend firefighting operations when switching from handheld nozzles to unmanned firefighting operations using portable monitors, and small-diameter water nozzles must be used. If you wish to continue firefighting by changing to a larger diameter foam nozzle, you will need to remove the nozzle already attached to the stand and reconnect other nozzles, resulting in a temporary suspension of firefighting.

In addition, the fixed legs limit the installation location, resulting in the inconvenience that the device cannot be installed in narrow spaces such as the upper end of a fence or a window frame.

The purpose of this invention is to eliminate the disadvantages of the above conventional example,
Since nozzles with different diameters can be freely mounted from the outside, it is possible to continue firefighting operations when switching from hand-held nozzles to using a portable monitor or when changing extinguishing agents. Since it is fixed, there is no risk of it coming off due to water pressure, etc. Furthermore, by operating the legs, it can be attached to roads, oil embankments, ditches, etc.
To provide a stand for a fire extinguishing nozzle that can be installed in any wide or narrow place such as a window frame.

However, according to the present invention, the purpose of the lever is a cross-shaped leg that tapers toward the tip, bends downward at the tip to form a latch claw, and whose front part can be bent downward and whose opening angle can be adjusted. A support body having a horizontally adjustable joint part and a vertically adjustable joint part is installed in the center of the support body, and a handle is attached to the upper part of the horizontal cylinder body that can be opened and closed with a hinge at the upper end of the support body. This is achieved by providing a nozzle clamping part whose tightening diameter can be freely changed, through which a threaded rod having a diameter is passed through, and a curved restraining plate that moves inside the cylinder is attached to the tip of the nozzle clamping part.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

and 2') with a set screw 8 on each leg.
It can be adjusted and stopped between each leg.

As an example, the fixing rod 7 is hingedly connected to one leg 2, 2', and the other leg 1, 1' is provided with a slit 9 through which a set screw 8 moves. All you have to do is adjust the length in step 7.

A support 10 is integrally erected on the central connecting disks 3, 3', and the support 10 has a horizontal angle-adjustable joint 11 and parallel flanges 12, 12' projecting thereon. The rotating shaft 15 is placed on the body 13.
It has a joint part 14 which is pivotally supported and whose angle can be adjusted in the vertical direction.

In the figure, 16 is a fixing screw for vertical rotation of the joint 14, which is attached through the slit of the flange 12;
Reference numeral 17 indicates a fixing screw for horizontal rotation of the joint portion 11, and reference numeral 18 indicates a handle for vertical and horizontal angle adjustment.

A horizontal base plate 19 is fixed to the upper end of the support 10,
A nozzle holding part 20 was provided on the base plate 19.

The nozzle holding part 20 is divided in the horizontal direction and has a hinge 21.
It consists of a short horizontal cylindrical body 22 with an upper body 22a opened through. A handle 23a is attached to the upper body 22a.
A threaded rod 23 having a diameter is passed through the rod, and a curved restraining plate 24 that moves within the cylinder body 22 is attached to the tip thereof.
In the figure, 25 is a fixing lock for the upper body 22a;
The diameter of the cylinder 22 is selected to be large enough to allow insertion up to the thick foaming nozzle side.

FIG. 2 is a partial perspective view showing a second embodiment of the frame of the present invention, in which a nozzle clamping part 20' of a vice structure is used in place of the nozzle clamping part 20 of the first embodiment. In the figure, reference numerals 27 and 27' indicate clamping pieces that open left and right, and reference numeral 28 indicates an opening/closing adjustment screw for the clamping pieces 27 and 27'. The other structures are the same as those in FIG. 1 of the first embodiment.

Next, the usage and operation of the first embodiment will be explained. In a place where there is sufficient installation area such as on a road or on a rooftop, the legs 1, 1' and 2, 2' can be fully opened to each other as shown in Fig. 3. Install the pedestal by spreading it out as shown and leaving each leg extended without bending the front part.

Remove the lock 25a, open the upper body 22a, put the side of the nozzle 26 inside the cylinder 22, close the upper body 22a and engage the lock 25, then turn the handle 23 to lower the restraining plate 24. The tightening diameter of the cylindrical body 22 changes, and the nozzle 26 is firmly clamped on the frame of the present invention. The illustrated nozzle 26 is a water discharge nozzle, and the tip of the nozzle 26 can be directed upward, downward, leftward, or rightward through the joints 11 and 14 of the support 10.

If you wish to change the nozzle 26 to the large diameter foaming nozzle 26' shown in Figure 4 during firefighting,
It is sufficient to remove the nozzle 26 from the holding part 20 and set a new foaming nozzle 26' without stopping water discharging from the nozzle 26.

On the other hand, when installing the pedestal of the present invention in a narrow place such as an oil barrier, a shed, or a window frame, as shown in FIG. 7 is adjusted through the slit 9 to narrow the distance between the legs 1 and 2, and 1' and 2'.
By bending the front part of each leg 1, 1', 2, 2' downward at a right angle via the joint 6, it can be securely and securely installed.

Furthermore, in order to store the frame when not in use, it takes up less space by removing the rotating shaft 15, separating the flanges 12, 12' and the column 13, and closing the legs 1, 1'. That's fine.

FIG. 5 is a perspective view showing a third embodiment of the frame of the present invention, in which a U-shaped connecting portion 29 is integrally raised from the central connecting disk portions 3, 3' of the legs 4, and one side is supported. The body 10' has a U-shaped fitting part 30 formed further below the joint part 11 that can adjust the left and right angle, and the fitting part 30 is fitted into the connecting part 29 from the outside and fixed with a screw 31. .

The method of use is the same as in the first embodiment, but as shown in FIG. 6, the legs 4 are removed and the support 1 is

A fixing method such as fitting the upper end of 2 and fixing with the screw 31 is also possible.

As mentioned above, the fire extinguishing nozzle mount of the present invention has cross-shaped legs that can be opened and adjusted in angle, and the leading edge has a downwardly bent latch claw, and the front part is bent downwards. Since it is possible to set it up freely even in a narrow place with a narrow width, for example, you can adjust the opening angle of the legs to match the width of the holder, or bend the front part as necessary. This makes it possible to accommodate frames of various widths.

In addition, since the pedestal directly holds the metal nozzle side, there is no risk of the nozzle coming off the pedestal even if there is a change in water pressure, etc., and the gripping part of this nozzle can be adjusted in the vertical direction on the legs. Since it is erected via a support having a joint part and a joint part whose horizontal angle is adjustable, the nozzle can be easily directed in any direction.

In addition, the nozzle holding part can be opened and closed, so you can open it and insert the center of the nozzle as is.
By changing the extinguishing agent between water and foam, the nozzle installed on the frame can be changed easily and quickly without interrupting firefighting activities.
