Beschreibung[en]

The invention relates to a transportable storage device, comprising a loading bay for storing a flexible hose, for example a fire hose, in a folded fashion, the loading bay having an opening at the back.

Such transportable storage devices, which are usually mounted on a road vehicle are known. The known vehicles are employed for recovering a fire hose after use. Hoses of this type are made up of a plurality of flexible hose sections which are provided with rigid couplings at both ends. Such vehicle is provided with an installation for taking up a flexible hose which has been laid out on the ground into the loading bay.

The retraction installation takes up the hose from the ground and transfers it into the loading bay where it is stored and folded in a zigzag like manner along the length of the loading bay. The loading bay may accommodate up to several kilometres of hose. The vehicle is driven along the fire hose at a speed which essentially corresponds to the speed at which the fire hose is taken up. The back of the loading bay has an opening for unloading the hose, the opening being closeable by doors

A problem with the known transportable storage device is the instability of the hose package in the loading bay. The hose is laid down in the loading bay in a folded manner, the hose forming a hose package. The hose package is spaced apart from the doors which close the opening at the back of the loading bay, so as to prevent bulging out of the hose package when opening the doors, which would impede closing of the doors. However, because of the space between the hose package and the doors of the loading bay, the folded parts of the hose are prone to shifting due to the movement of the loading bay during transport. In particular upon unloading the loading bay from the vehicle, in which process the loading bay is tilted backwards, the hose package may shift in such a way that it abuts the door. Especially the folded parts of the hose that lie near the top of the hose package are likely to shift because they are not fixated due to friction by the weight of the hose package.

The aim of the invention is therefore to provide a transportable storage device as described above which provides for a more steady fixation of the hose package in the loading bay.

This aim is achieved in that the loading bay has an internal narrowing towards the opening. This narrowing provides an abutment and provides a compressing action on the hose package when it shifts towards the opening. An inwardly compressing action on the folded parts of the hose is obtained at the narrowing. The hose parts are pressed against each other and are thereby fixated due to friction.

Preferably, in this connection, the narrowing section of the loading bay provides a gradual reduction of an internal cross-sectional dimension of the loading bay. Moreover, this has the advantage that the rigid couplings at the end of the hose sections will slide past the narrowing essentially unobstructed, when removing the hose through the opening at the back of the loading bay.

The narrowing can be applied according to several possible embodiments. According to a first possibility, the narrowing may extend over at least part of the height of the loading bay. In particular, good results are obtained in case the narrowing extends over the upper part of the loading bay only, that is at a distance spaced apart from the floor of the loading bay.

Such location of the narrowing will also stabilize the hose package, despite the reduces extent of said narrowing. The lower part of the hose package is fixated anyway due to the load exerted thereon by the upper part of the hose package and the fiction which is generated as a result thereof in said lower part. However, the loosely packed upper part or middle part of the hose package tends to shift away upon tilting of the loading bay, and at precisely those heights the advantageous effect of the narrowing comes into play.

The narrowing may be positioned at different locations along the length of the loading bay. Preferably, the narrowing is at or near the opening of the loading bay. At that location, the narrowing provides an obstruction which draws the loops in the hose package closer together and prevents them from falling out through the opening. However, the beneficial effect of the narrowing is also obtained in case said narrowing is somewhere in between the back end opening and the front end of the loading bay.

Also at that location, the narrowing has the effect of drawing the loops, in particular in the upper ones as explained before, closer together so as to enhance the mutual friction therein as well as between the loops and the walls of the loading bay. As an example, this effect is obtained in case the narrowing is positioned somewhere in the middle between the front end and the back end of the loading bay.

The gradual reduction in width is readily obtained by providing a guiding element, such as a guide plate, on at least one of the sidewalls of the loading bay, near the closeable opening thereof, which extends obliquely into the loading bay. The guide plate may be supported by a strip which is adapted to the corresponding wall of the loading bay for example by providing notches for accommodating the various devices on said wall, like hinges, locks etc.

Preferably the loading bay is removably mounted on the vehicle chassis, for example on a support which is tiltable, the loading bay being slideable with respect to the support for loading/ unloading the loading bay on the vehicle. Such a construction is well known in the art.

Especially when using a tiltable support for the loading bay it is of importance to space apart the hose package from the doors. The hose package has considerable weight, would it rest against the doors during tilting of the loading bay, usually more than 35°, the doors could not be closed again after they have been opened.

The retraction installation for taking up the hose is usually mounted on the vehicle. Alternatively however, said installation may also be mounted on the storing device.

The invention also relates to a loading bay as described above.

The invention will now be described referring to the accompanying figures, wherein:

  • Figure 1 shows, partially in cross section, a vehicle according to the invention.
  • Figure 2 shows a top view of the loading bay according to the invention.
  • Figure 3 shows a partial perspective view of the back of the loading bay.

The vehicle 1 according to the invention shown in figure 1 comprises a loading bay 2 for storing a flexible hose 3. The hose which has been laid out on the ground 4 is taken up and transferred into the loading bay 2 by means of retraction installation 5. The loading bay has a closeable opening 6 at the back for unloading the hose.

The hose 3 is made up of a plurality of flexible hose sections 9 which are provided with rigid couplings 10 at both ends

The hose 3 is stored in a folded manner, forming a hose package 7. As can be seen in figure 2, the hose package 7 is spaced apart from the doors 8 at the back of the loading bay 2 to prevent the hose from bulging out when opening the doors 8, and to prevent overloading the doors 8 when tilting the loading bay 2 backwards upon unloading it from the vehicle 1.

The loading bay 2 comprises a container 11 which is removably mounted on the vehicle 1. In this embodiment the container is slideable with respect to a tiltable support 12. For unloading the container 11 from the vehicle, the support 12 is tilted backwards and the container is slid of the support.

Figure 2 shows the container 11 having a narrowing 13 towards the back near the closeable opening 6. This narrowing provides an abutment and provides an inwardly compressing action on the hose package 7 when it shifts towards opening 6, thereby pressing the folded parts of the hose against each other and holding them due to friction.

The narrowing section 13 of the container 11 provides a gradual reduction in width of the loading bay 2 so as to promote the compressing action. In addition, this has the advantage that the rigid couplings 10 at the end of the hose sections 9 will slide past the narrowing 13 essentially unobstructed, when removing the hose 3 through the opening 6 at the back of the container 11.

The narrowing is obtained by guiding elements comprising guide plates 14 provided on the side walls of the container 11, near the closeable opening 6 thereof. The guide plates 14 extend obliquely into the loading space of the container 11, and are supported by a strip 15. This strip is adapted to the corresponding wall of the container by providing notches 16 for accommodating the various devices on said wall, like the lock 17. Alternatively, the narrowing may be carried out as a plastic insert, or may be integrated in the walls of the container 11.

The guiding elements may extend over just the upper part of the height of the container 11, thus acting on just the upper part of the hose package 7, as the lower part of the hose package 7 will already be fixated due to friction caused by the weight of the upper part of the hose package 7.

Although in the foregoing reference has been made to the application of the transportable storage device on a lorry, the invention is not limited to such application. For instance, the transportable storage device according to the invention can also be accommodated on board a ship, or can be transported by means of an aircraft, hoovercraft etc.
