Definitions

• the present invention relates to devices for storing and pack- ing, respectively, water hoses provided with afterglowing means as well as a water hose coated by afterglowing means accord ⁇ ing to the preamble of the appended independent claims.
• a water hose of this type is already known through for example AT patent No. 209 647 in which it is used in dark spaces, pri ⁇ marily in mines, but it is also well suited for use in smoke diving for assisting the persons using the hose in thick smoke and/or darkness by means of a glowing hose to find the way back to the starting point, but also other fields of use are possible.
• said afterglowing means which may consist for in ⁇ stance of strips of a certain colour glued on the hose or such paint directly applied on the hose, glowing it is necessary that it is illuminated during a shorter period of time, so that it is acti- vated and then emits light during a longer period of time of for example about half an hour.
• Hoses of this type have in most cases to be moved very rapidly to one place, such as the place for a fire, so that they have to be compactly stored in a con ⁇ tainer, on a drum or in another similar way.
• the object of the present invention is to provide devices as well as a hose of the type defined in the introduction, which solve the problems discussed above in a rational way.
• said members comprise spacers adapted to be arranged in a plural- ity of rows located at a distance from each other as seen in the direction in which hose lengths received in the container are intended to extend and being substantially in parallel with each other with two adjacent spacers from each row defining a path for a hose length therebetween together with corresponding spacer pairs of the other rows.
• the device comprises a box-like housing member having a room, into which the container is intended to be introduced, and means arranged on and along inner walls delimiting the room and located opposite said side when the container is intro ⁇ quizzed, the latter means being adapted to emit light towards the hose for activating the afterglowing means thereof.
• a de ⁇ vice enables an efficient storing while offering good possibilities to activation of the afterglowing means in the storing state of the hose, thanks to the inventional construction of the cassette ⁇ like container, and the housing member adapted for receiving thereof and provided with light emitting means on said inner walls.
• the cassette-like container may be taken out of the housing member and carried along to a suitable location for use, so that it is not necessary to carry the very housing member along.
• the latter is preferably placed in for instance a fire engine and connected to the electrical system thereof, in such a way that activation of the afterglowing means of the hose is started as soon as the ignition of the fire engine is activated.
• the water hose coated with an afterglowing means according to the appended independent claim is efficiently protected against damages from the outside and dirt and dust depositions thereon without any reduction of the light absorbing and emitting capac ⁇ ity thereof thanks to the coating thereof by a transparent poly ⁇ meric material for protecting the afterglowing means.

• FIG. 1 A device for packing a water hose 1 is illustrated in Fig. 1 , the jacket of which is provided with an afterglowing means not shown in a way to be described further on. Only one cut portion of the hose 1 is shown in the figure so as to improve the clear ⁇ ness. It is the question about a so called flat rolled pressure hose for fire-fighting, which is in the storing position thereof in ⁇ tended to be packed in a carrier 3 insertable in a container 2 (see Fig.
• pin-like members 5 which comprises a substantially rectangular frame 4 on which pin-like members 5 are arranged in a plurality of rows 6 being substantially in parallel with each other and ar ⁇ ranged at a distance from each other in the direction in which hose lengths received by the carrier are intended to extend, so that each of these rows by that will get a comb-like appearance.
• the pin-like members 5 are of the same number in every row and all are arranged at the same distance, so that two adjacent members from each roll will therebetween define a way for a hose length together with corresponding member pairs of the other rows. Accordingly, the pin-like members 5 function as spacers arranged to separate two consecutive wall lengths, and they are arranged to extend transversally to the longitudinal di ⁇ rection a hose co-operating therewith is intended to have.
• a hose 1 is intended to be thread from one side of the carrier 3, as shown in Fig. 1 , first between the first two pin-like spacers 5 of each row 6 and after that be folded through a fold 7 about a spacer of an outer row so as to after that be led back in a hose length being substantially in parallel with the first hose length between the second and third spacer 5 of the re ⁇ spective row so as to after that be folded in a new fold 8 about the third spacer of the opposite outer row of spacers and so on until the entire hose 1 has been packed in this way.
• the container 2 is open from the oppo ⁇ site side and adapted to receive the carrier 3 packed with the hose from the opposite sides in such a way that the pin-like members 5 point towards the interior of the container and are terminated at a distance from the pin-like members of the re ⁇ spective other carrier and by that a space is formed inside the container between the two carriers.
• One short-wall 1 1 of the container 2 has a central opening 12 from the top and down ⁇ wards, the dimensions of which substantially correspond to said space in order to enable a light emitting means to be introduced into this space in a way which will be explained further on.
• two hoses may be stored in the container 2, and it is pos ⁇ sible to either fill out only one hose, when the length thereof will be sufficient, or in cases when a very long hose is required to interconnect the two hoses to one single hose when they are to be used later on.
• a handle 13 is arranged at one end of the frame 4 and it is in- tended to be pulled outwardly form the container in the way shown in Fig. 3 when the hose is to be used, so that the spac ⁇ ers 5 leave the hose and the hose lengths through the gravita ⁇ tion fall flat onto each other.
• the carrier is then to be com ⁇ pletely removed from the container 2.
• the rod-like members 9 will ensure that the hose will remain inside the container. It is then easy to rapidly pull out an appropriate length of the hose from the container without any noticeable resistance.
• the hose is then preferably running on rotating rollers not shown in the figures arranged on one cable 14 of the container.
• the container is portable through the existence of a handle 15. It has also a handle 16 for facilitating the introduction and pull ⁇ ing outwardly thereof in a box-like housing member 17, in which the container 2 is introducable like a cassette for storage therein.
• Light emitting means 19 in the form of fluorescent tubes are arranged around inner walls 18 of the housing member op ⁇ posite to the large open walls 2' of the container.
• a fluorescent tube loop 20 extends also from one short-wall of the housing member centrally into the housing member for introduction thereof in said space between the two layers 3 of the container 2 introduced into the housing member.
• the fluorescent tubes are through a cable 21 provided with a plug contact connectable to electrical power, such as the electrical system of a fire en ⁇ gine for emitting light in the direction towards the hoses of the container.
• the water hose stored in the container is carried by the spacers through the substantially horizontal extension of the hose lengths, so that adjacent hose lengths are kept at a well defined distance from each other and substantially the entire surfaces of the hose will in this way be accessible for light ap ⁇ plied on the respective open container side 2' and for light ap ⁇ plied from said space.
• the invention does also provide a hose having the following characteristics for packing in the container discussed above so as to obtain a dirt rejecting hose having a high wear resistance of the afterglowing means applied.
• the jacket of this water hose is coated by a transparent polymeric material for protecting the afterglowing means, said jacket of the hose being either directly coated by a first layer of afterglowing means or agent in the form of afterglowing crystals, which has been covered by a second layer of transparent polymeric material, or the jacket of the hose is coated by a mass of transparent polymeric material having an afterglowing agent intermixed therewith.
• the poly ⁇ meric material is advantageously polyvinylchlorid.
• the afterglowing hose When the afterglowing hose is used, for instance after a fire alarm, it functions in the following way: electricity is applied to the fluorescent tubes 19, 20, preferably in connection with starting the fire engine, so that the fluorescent tubes 19, 20 emit light into the spaces created by the spacers 5 between the hose lengths during the ride to the place for the fire. Thanks to the fact that the spacers keep the hose lengths apart the light reaches substantially all the surfaces of the hose and activates the afterglowing means thereof. At the arrival to the place for the fire the hose is then "charged to the top", and the container 2 is pulled out of the housing member 17 and carried in the handle 15 to a suitable place for connecting the hose to a water source. When the hose is then to be pulled out the respective carrier 3 is then firstly rapidly removed by pulling the handle 13 and the hose is then pulled out over said rotating roller not shown, in which the hose lengths are following each other out of the contanier.
• a second device for packing a water hose 1 for transferring thereof into a container shown in Figs. 6 and 7 of a second de ⁇ vice for storing a hose provided with afterglowing means is il- lustrated in Fig. 5.
• This packing device comprises a carrier 2 having a sheet member 23 and at the opposite ends thereof op ⁇ positely directed support members or stops 24, 25 protruding substantially perpendicularly thereto.
• a lower flange 26 pro ⁇ trudes substantially perpendicularly from the sheet member 23 along one edge of the sheet member connecting the support members 24, 25.
• a handle 27 for lifting the carrier and assisting in handling the carrier is arranged centrally on the flange 26.
• the carrier will in this way get a case-like character with the sheet member 23 as one large wall and the support members 24, 25 as sides of a briefcase construction having no second large wall and no bottom.
• the flange 26 does not extend all the way to the respective support member, so that openings 28 for passing of the respective end portion of a hose are formed.
• a spacer 32 is introduced from the opposite end 31 of the carrier, so that it reaches the fold opening in question and the fold will come into abutment towards the flange 26.
• the spacers 32 are formed by elongated discs or sheets of material being permeable to light, such as plexiglass, having a thickness of for instance 4 mm so as to keep consecutive hose lengths sufficiently spaced apart for enabling light to reach into the space therebetween and activate afterglowing means applied on the hose.
• the width of the spac- ers corresponds substantially to the width of the hose in the flat state, and the length thereof exceeds the intended length of each hose length, so that they will at the free end thereof pro ⁇ ject with a portion 33 out of said space. This portion 33 is pro ⁇ vided with a through-hole 34, the task of which will be explained further below.
• the hose is in this way packed with spacers located between every second hose length on the sheet member 23, from one support member 24 to the other support member 25 while ob- taining a package-like assembly on the carrier.
• the two hose lengths are then led out through the respective opening 28 in the flange 26, so that coupling members 35 located there will be located outside the very package and also will be easily ac ⁇ cessible later on for interconnection with other hoses, a water source or the like.
• a container 36 in which the hose packed according to the method illustrated in Fig. 5 is intended to be stored is illustrated in Fig. 6. It is illustrated in Fig. 7 how such a storage is in- tended to take place.
• the container has a lid 37 pivotably ar ⁇ ranged for offering access to the container, and after creating the package-like assembly on the carrier 22 the handle 27 is gripped and the carrier 22 is pushed with the end 31 first into the opened container, so that the extremity of the spacers 32 reaches the bottom 38 thereof. When the carrier 22 is then pulled out of the container the gravitation will then ensure that the package-like hose assembly will remain in the container.
• a rod 39 is brought through the holes 34 of the row of spacers 2 and this rod is connectable to opposite end walls 40, 41 of the container through holes 42 applied therein and securable to one end wall through locking tongues 50.
• Two hoses may in this way be arranged in two parallel rows located next to each other, in which the ends of these hoses may be interconnected through these coupling members, so that in practise one single long hose is obtained.
• the large walls of the container located in parallel with the re ⁇ spective hose row are thoroughly formed by two thin rods 43 for lateral support for the hoses, so that these walls offer a good accessibility to the hoses for illumination of the afterglowing material thereof.
• This container 36 is also portable and has for this sake a han ⁇ dle 44 and it is, as shown in Fig. 8, introducable like a cassette into a box-like housing member 45 for storage therein.
• Light emitting means 47 in the form of fluorescent tubes are arranged along inner walls 46 of the housing member 45 located opposite to the large walls of the container. These fluorescent tubes are connectable to an electrical power, such as the electrical sys- tern of a fire engine, through a cable 48 provided with a plug for emitting light in the direction towards the interior of the con ⁇ tainer 36.
• the use of the device according to this embodiment of the in- vention corresponds substantially with that of the device ac ⁇ cording to the first embodiment, and how this is carried out will be apparent through reading the description above.
• the water hose is pulled out over a rotating roller 49 arranged at the lid of the container (Fig. 6), whereby the hose lengths are following each other out of the container while leaving the spacers 32 therein thanks to the rod 39 pene ⁇ trating through the holes 34.
• a comparatively good illumination of the hose and by that activation of the afterglow ⁇ ing means may take place in the storage state of the hose, al ⁇ though this embodiment in this respect will not come close to the efficiency obtainable in this respect through the first em ⁇ bodiment, since every hose length in this second embodiment after all will bear at one side directly against an adjacent hose length without any space therebetween and the spacers of plexiglass may of course not let just as much light through as air.
