Spray nozzle for a hire hose

Abstract

 Spray nozzle for a fire-hose, comprising a connecting opening for a fire-hose in a first outer end of the spray nozzle, a spray aperture in the second outer end of the spray nozzle, a throughfeed channel connecting the connecting opening for the fire-hose and the spray aperture, and a movable valve which can close the throughfeed channel, wherein the spray nozzle is provided with an at least partially phosphorescent outer surface.

Description

[0001] The invention relates to a spray nozzle for a fire-hose, comprising a connecting opening for a fire-hose in a first outer end of the spray nozzle, a spray aperture in the second outer end of the spray nozzle, a throughfeed channel connecting the connecting opening for the fire-hose and the spray aperture, and a movable valve which can close the throughfeed channel.

[0002] Such a spray nozzle for a fire-hose is generally known. Fire-hoses hang in many buildings, rolled up on reels, in for instance corridors and rooms. A problem which occurs here is that fire in a building often results in power failure. This can produce dangerous situations. The invention has for its object to combat these dangers.

[0003] For this purpose at least a part of the surface of the spray nozzle is provided with a phosphorescent material. Because a phosphorescent material continues to emit light for a considerable time after the ambient light has disappeared, people in the building can readily identify and find the outer end of the fire-hose in the dark.

[0004] The phosphorescent outer surface is preferably annular, and the phosphorescent outer surface is preferably the outer surface of a phosphorescent ring. It is not therefore necessary to manufacture the whole surface from phosphorescent material.

[0005] The phosphorescent outer surface preferably extends close to the spray aperture, and the phosphorescent outer surface more preferably encircles the spray aperture. It is in this way apparent where the outer end is situated.

[0006] The invention also relates to a fire-hose provided with a spray nozzle.

[0007] The invention will be further elucidated on the basis of an exemplary embodiment shown in figures, in which:

Figure 1 shows a fire-hose provided with a spray nozzle; and

Figure 2 shows the spray nozzle of Figure 1.

[0008] Spray nozzle 1, which according to Figure 1 is mounted on the outer end of a fire-hose 6 on a reel 7, has on a first outer end a connection 2 for fire-hose 6. Connection 2 is connected to internal parts (not shown) of spray nozzle 1 in which is located a water throughfeed channel. A rotatable handgrip 3 is placed over the internal parts of spray nozzle 1. Handgrip 3 is manufactured from a red plastic. Handgrip 3 is provided at the second outer end of the spray nozzle with a white-yellow phosphorescent plastic ring 4. Spray aperture 5 of the water throughfeed channel of the internal parts is situated in the opening of phosphorescent ring 4. By rotating handgrip 3 about its axis a valve in spray aperture 5 is either closed or opened such that the water throughfeed is completely closed or that a water jet or water mist is created as required.

[0009] Ring 4 is for instance manufactured from an epoxy incorporating a phosphorescent pigment. An example of a phosphorescent pigment is Luminova (TM) which is commercially available. More examples of phosphorescent pigments and suitable epoxies are described in US 6,005,024. Ring 4 will be luminescent in the dark if the light in the vicinity of fire-hose 6 fails. Spray nozzle 1 can hereby be readily found in the dark.

[0010] Although the invention is described here on the basis of one exemplary embodiment, the invention is not limited thereto. The scope of the invention is therefore defined solely by the appended claims.

Claims

1. Spray nozzle 1 for a fire-hose 6, comprising a connecting opening 2 for a fire-hose 6 in a first outer end of the spray nozzle 1, a spray aperture 5 in the second outer end of the spray nozzle, a throughfeed channel connecting the connecting opening 2 for the fire-hose 6 and the spray aperture 5, and a movable valve which can close the throughfeed channel, characterized in that at least a part 4 of the surface of the spray nozzle 1 is provided with a phosphorescent material.

2. Spray nozzle as claimed in claim 1, wherein the phosphorescent outer surface is annular.

3. Spray nozzle as claimed in claim 2, wherein the phosphorescent outer surface is the outer surface of a phosphorescent ring 4.

4. Spray nozzle as claimed in claim 1, 2 or 3, wherein the phosphorescent outer surface extends close to the spray aperture 5 of the spray nozzle 1.

5. Spray nozzle as claimed in claim 4, wherein the phosphorescent outer surface encircles the spray aperture 5.

6. Fire-hose 6 provided with a spray nozzle 1 as claimed in any of the foregoing claims.
