Description

Title of the invention: Fire truck comprising a horizontally arranged hose reel Scope of the invention

[0001] The present invention relates to the field of firefighting vehicles equipped with a hose reel,

[0002] This includes fire engines known as fire engines (abbreviated FPT), whose primary purpose is firefighting. This type of fire engine is equipped with both a pump and a tank, i.e., a water reservoir. Its equivalent in other countries includes, among others, the Tanklôschfahrzeug (TLF) in Germany, the multi-functional fire engine (APMF) in Belgium, the Engine in the United States, and the Tonne-pompe in Switzerland.

[0003] The fire engine has a pump with a flow rate of 1,000 to over 3,000 L / min driven by the engine via a clutch and a water tank (the tonneau) with a capacity of 1,000 to 6,000 L. It may also include a foam concentrate tank (up to 500 L) for producing foam.

[0004] In the side lockers is stored a large quantity of equipment; mainly firefighting equipment (nozzles, hoses, fittings and dividers, foam, extinguishers, chimney fire kit, electrical fire), operational ventilation and rescue equipment.

[0005] At the rear there are often two mobile hose reels, each equipped with 200 m of 70 mm hose. There is also a rotating hose reel nozzle (called "LDT" or "pissette" in firefighter jargon) supplied directly by the water reserve, equipped with four 20 m semi-rigid hoses plus an additional 2 m length.

[0006] The FPT is the main truck used for firefighting. It can operate alone on fires of a certain size, since it can also deploy and supply three large hoses up to 400 m, connected to a water source, a fire hydrant or a pump in a watercourse, isolated reservoir, swimming pool, etc. State of the art

[0007] Prior art patent FR2710273A1 describes an intervention van, intended for intervention and the transport of equipment to the scene of an incident, the chassis of which supports an equipment module fitted with at least one hose reel, accessible from the outside and mounted on support arms. This van is characterized in that the equipment module is protected by a bodywork element partially covering the reels, so as to make its length Overall, independent of the position of the support arms. US patent 10071670 also describes a hose reel device for jet cleaning sewers comprising a reel, a hose wound around the reel, a reel frame that holds the reel, and a cover device. The reel frame with the reel can rotate about an axis perpendicular to a horizontal mounting surface. The cover covers most of the reel and its frame. The cover can be selectively moved to expose a portion of the reel and allow access to the hose. The cover is fixed in position relative to the rotating reel frame and the reel. Disadvantage of prior art

[0008] In prior art solutions, the hose reel(s) are arranged transversely or longitudinally, around a horizontal axis.

[0009] When the reel is embedded in the body of the vehicle, it occupies a significant amount of space to the detriment of the equipment or people that can be taken on board the vehicle.

[0010] When the reel(s) are installed transversely at the rear of the vehicle, they also present a detrimental bulkiness.

[0011] Furthermore, to accommodate such reels in the available volume, it is necessary to provide a maximum cross-section compatible with the internal dimensions of the vehicle, which requires reducing the radius of curvature of the hoses, thus causing a pressure loss when the hose is only partially unwound.

[0012] Furthermore, the lateral or rear position makes it more difficult to use the opposite side of the vehicle, which obstructs the deployment of the hose. Solution provided by the invention

[0013] To overcome these drawbacks, the present invention, in its most general sense, relates to a fire engine comprising a hose reel, characterized in that said hose reel is mounted to pivot about a vertical axis, for example, on the roof or chassis of the engine. The reel is arranged horizontally, that is to say, the median plane, perpendicular to the axis of the reel, is parallel to the plane passing through the axles of the engine's wheels, and to the ground when the engine is on flat, level ground.

[0014] Advantageously, said hose reel has at its lower part an axial connection for the fluidic supply of said hose.

[0015] According to one variant, said hose reel is motorized.

[0016] According to another variant, said hose reel supports a double-conduit two-phase hose.

[0017] Detailed description of a non-limiting example of embodiment

[0018] The present invention will be better understood upon reading the following description, concerning a non-limiting example of an embodiment illustrated by the accompanying drawings where:

[0019] [Fig-1] Figure [Fig.1] represents a top view of a fire truck

[0020] fire truck according to the invention

[0021] [Fig.2] Figure [Fig.2] shows a three-quarter rear view from below of a fire truck according to the invention

[0022] [Fig.3] Figure [Fig.3] shows a rear view of a fire truck according to the invention Principle of the invention

[0023] To address the drawbacks of the prior art, the invention proposes a fire truck formed by a motor vehicle (1) whose roof (2) supports a hose reel (10) pivoting around a vertical axis.

[0024] The hose reel (10) has a diameter corresponding substantially to the width of the vehicle, ± 10%, so as to maximize the length of hose that can be wound on the hose reel (10) on the one hand, and to reduce the radius of curvature and consequently the pressure losses on the other hand.

[0025] In the example described, a fluidic outlet (11) has a fluidic connector for connecting one end of the pipe (15).

[0026] This fluidic outlet (11) is extended by a segment (12) axially passing through the hose reel (10) and ending with a second fluidic connector (13) for connection to a water pump.

[0027] This solution avoids the use of a rotary joint. It also allows the implementation of a two-phase system, illustrated by [Fig.3], with pipes (15), connectors (16, 17) and a segment (12) having two coaxial sections, one for supplying a nozzle with water and the other for supplying this nozzle with air.

[0028] The hose reel (10) is, according to an option, motorized, with a torque sensor ensuring the control of the motor in order to assist the unwinding or rewinding of the hose (15) around the reel (10).
