Description

IMPROVEMENT FOR A FEEDER SUPPORT DEVICE

PIPE MOBILE

  The present invention relates to an improvement for a mobile hose reel support device of the type intended in particular to equip a fire-fighting vehicle. This support device is intended to allow the reels to be transported outside the vehicle and to facilitate loading and access during

  interventions in order to limit their size.

  Intervention vehicles used in fire fighting generally have a tank connected to a set of pumps, and carry their hoses arranged on mobile hose reels. These reels are, in a manner known per se, preferably transported outside the vehicle, in order to be able to be quickly loaded before its departure to reduce intervention times as much as possible and to facilitate their activation on site, the factor time being one of the most important parameters in the fight against claims. Support devices for mobile hose reels are known in the prior art, such as those of the applicant's patent published under the n FR. 2,710,273, which has two pivoting support arms arranged on a cross member located at the rear of the vehicle and on which the reel is positioned in cantilever, after being straightened to be immobilized in the transport position, in a manner known per se . Support devices are also known, the support arms of which are articulated in a motorized manner between a low loading position and a transport position in a horizontal plane, in order to avoid the user having to lift the reel to position it. However, these devices are generally expensive, and

  require the use of cylinders.

  The conventional devices described above have drawbacks due in particular to the positioning of the support arms in the transport position, said positioning is ensured by a device of the pin type which leaves the support arm with a certain amount of angular movement or displacement. Thus, during the loading of the reel on the support device, the positioning of the forks thereof on the portions of axes carrying the anchor points of the support arms, can be difficult because of their respective movements which hinder the installation. In addition, once the reel placed in the transport position, its inertia on the support arms combined with their respective deflections, can prove to be troublesome during the journey of the vehicle and causes

  significant wear of the parts constituting the support device.

  The present invention aims to solve the aforementioned drawbacks of conventional support devices of the art

  prior, using simple, reliable and easy to implement means.

  It offers a mobile hose reel support device which facilitates the positioning of said reel on the anchoring points and which limits unwanted movements or oscillations of the reel and

support arms.

  Thus, according to its main characteristic, the support device for a mobile hose reel according to the invention is of the type intended to be fitted in particular to emergency vehicles, said support device being of the type comprising two support arms movable between a passive folded position and a active transport position o they extend substantially parallel to allow the cantilever installation of a mobile hose reel, and is characterized in that it comprises on at least one of the support arms immobilization means intended to allow complete immobilization of the arm

in its active position.

  According to an additional characteristic of the support device for a mobile hose reel, the latter is characterized in that the support arms consist of a base, on which is articulated an arm pivoting about an axis, the immobilization means being formed by cooperation between abutment surfaces located on

  the base and support surfaces integral with the pivoting arm.

  According to another characteristic of the support device for mobile hose reel, the abutment surfaces are formed by the side walls of a locking groove located on the bottom wall of the base and in that the bearing surfaces are formed by the side walls of an immobilization projection disposed under the edge

lower of the swivel arm.

  According to a complementary characteristic of the support device for mobile hose reel, the transverse profile of the immobilizing projection is identical and complementary to that of the locking groove. According to an alternative embodiment of the support device for mobile hose reel, the locking groove and the projection

  immobilizers have a transverse profile of trapezoidal shape.

  According to one embodiment of the support device for mobile hose reel according to the invention, the base comprises a lower wall and an upper wall, each having a groove of

locking.

  Furthermore, the support device for a mobile hose reel according to the invention comprises positioning means intended to set up the immobilization means automatically, when the support arm passes from its passive folded position to its active position.

transport.

  According to the preferred embodiment of the support device for mobile hose reel, characterized in that the pivoting arm is mounted so as to be able to slide along its axis against elastic return means during its pivoting, the positioning means being constituted in part by an inclined ramp device capable of causing the arm to slide during its pivoting, in order to allow the positioning of the immobilizing projection in the locking groove, when the pivoting arm is in position

active transport.

  According to another characteristic of the support device for mobile hose reel, the unlocking means comprise gripping means arranged near the articulation of the pivoting arm and intended to allow the user to slide said arm

  on its axis against the elastic return means.

  According to another alternative embodiment of the support device for a mobile hose reel according to the invention, each support arm of the

  support device is provided with immobilization means.

  Other characteristics and advantages of the invention will emerge

  Figure 9b is a view similar to Figure 9a, the arm being in the active position and shown in section at the locking projection. Figures 10a, 0lob, show an alternative embodiment in

  similar views to Figures 8a and 7b.

  According to the invention, the intervention vehicle bearing the general reference (1) illustrated in FIG. 1 is intended to be equipped with a support device (2) for a mobile hose reel (3) and comprises, for example, a transverse beam. rear (4), also called cross member, on which is intended to be disposed the support device. The support device (2) has two support elements, such as arms (6, 7)

  on which is intended to come to position the mobile reel (3).

  In a manner known per se, the support arms (6, 7) have at their free ends (6a, 7a) anchoring points (8) such as, for example, portions of axis on which are intended to be positioned end forks (9) arranged on the frame (10) of the reel (3), said frame being extended by a handle (11) carrying a grip handle (12). The frame (10) of the reel has the shape of a U whose side walls carry the forks (9) and form the joint between the frame and the axis (13) of the reel (3). Thus, the frame (10), its handle (11, 12), and its forks (9) pivot around the axis (13) of the reel on which the hose is wound and vice versa. Of course, the reel (3) comprises a coil (30) around which is

coiled a pipe (31).

  Figures 2a, 2b, 2c, 2d illustrate the different phases of the establishment of the reel (3). Previously, the user should deploy the corresponding support arms (6, 7) to pass them from the inactive position (B), as illustrated in Figures 3, 5, 9a, to the active deployed and locked position. , illustrated in Figures 4, 6, 9b. Thus, after positioning the support arms (6, 7) the user approaches the reel (FIG. 2a) to hang it on the axes of the arms by its forks (9), as illustrated in FIG. 2b. After the installation of the reel (3) on the support device (2), the complete installation on the vehicle is carried out by rotating the frame (10) once the forks (9) are positioned on their points of anchoring (8) for lifting the reel and fixing the handle (11) or its handle (12) in fixing means (5) arranged at the rear of the vehicle, the reel thus being entirely suspended

to the vehicle.

  The support arms (6, 7) are arranged on the crosspiece (4), of

  swivel, on the one hand in order to be able to line up along it

  ci in a passive folded position (B) illustrated in Figure 3, which allows for example, to facilitate the coupling of a trailer vehicle to the emergency vehicle (1), and secondly in order to be able to position itself substantially orthogonally to the cross member (4) so as to extend towards the rear of the vehicle (1) in an active position (A) called transport, illustrated in FIG. 4, to receive a mobile reel (3), such

as illustrated in Figures 2b, 2c, 2d.

  According to the invention, the support device (2) comprises immobilization means (MI) of at least one of the support arms (6, 7) intended to allow its complete immobilization and its locking in its active transport position (A ) relative to the crossmember (4) or to the chassis

of the vehicle (1).

  According to the preferred embodiment of the support device (2) for mobile hose reel (3), the support arms (6, 7) each consist of a base (14), on which a pivoting arm (15) is mounted articulated around an axis (16), as shown in Figures and 6, said base being intended to be fixed on the crosspiece (4), by any means, such as bolting or welding. The immobilization means (MI) are intended to allow complete immobilization and locking of the pivoting arm (15) relative to the base (14) in its active position (A), so as to eliminate any angular movement

  or play of said arm (15) around its axis (16).

  According to the preferred embodiment of the support device, as shown in Figures 5 to 9, the immobilization means (MI) are obtained by the cooperation between abutment surfaces (17a, 17b) arranged on the base (14) and complementary bearing surfaces (18a, 18b) located on the pivoting arm (15) or at least integral with it. Note that to immobilize the rotation of the arm (15) respectively in the two directions of rotation, two bearing surfaces (18a, 18b) and two complementary abutment surfaces (17a, 17b) are necessary. According to the preferred embodiment of the invention, the abutment surfaces (17a, 17b) are constituted by the side walls of a locking groove (19) located on the base (14), said groove being arranged in a horizontal plane, so as to extend in the same direction as that of the swivel arm, when the latter is in the active position

  transport (A), advantageously directly above it.

  This locking groove (19) is intended to cooperate with an immobilizing projection (20), advantageously arranged under the pivoting arm (15) as illustrated in FIGS. 7a and 7b, and the side walls of which constitute the bearing surfaces (18a, 18b) complementary responsible for cooperating with the abutment surfaces (17a, 17b) of the base (14), to obtain perfect immobilization of the arm by the immobilization means (MI). The transverse profile of the locking groove (19) is advantageously identical to the respective profile of the immobilization projection (20), as shown in FIGS. 7b and 8, said profile advantageously being of trapezoidal shape. Therefore, when the pivoting arm (15) is positioned in the active transport position (A), the respective side walls of the projection (20) and of the groove (19) cooperate in abutment on most or all of the length of the projection or of the groove to obtain the immobilization of the pivoting arm. It goes without saying that the configuration of the immobilization means could be different without departing from the claimed protective fields of the invention. According to the invention, the support device (2) has positioning means and unlocking means intended to allow on the one hand the pivoting arm to be put in place in its active position and immobilized by the means of immobilization in the latter automatically when it performs its pivoting movement from its passive folded position (B) to its active transport position (A), and on the other hand to avoid untimely unlocking of the support arms (6, 7) when they are immobilized in the active position (A), said unlocking can only be carried out when the user voluntarily actuates the unlocking means to bring the support arm (6, 7) back into its

passive folded position (B).

  According to the preferred embodiment, the positioning means are constituted in part by a system for sliding the pivoting arm (15) relative to the base, along the pivot axis (16), said sliding s '' performing against elastic return means (MRE). Furthermore, these means comprise an inclined ramp device (24), located on the base (14) which is intended to cause, during the pivoting of the arm (15), the sliding thereof along its axis ( 16) against elastic return means (MRE). Thus, when the pivoting ends and the arm (15) passes into its active position (A), the elastic return means (MRE) urge the arm so as to cause cooperation between the projection (20) and the groove ( 19), said cooperation thereby immobilizing the pivoting arm

  (15) in its active transport position (A).

  According to the preferred embodiment, the locking groove (19) extends over the lower wall (22) of the base (14), while the immobilization projection (20) extends below the arm pivoting (15) along its lower edge (23). Note that the inclined ramp (24) is disposed on the base (14), so as to be able to cooperate with the lateral face (18a) of the projection (20) to cause the vertical sliding of the arm (15) against of the return force of the spring (21) as the

show Figures 8 and 9.

  In addition, it is important to note that the base (14) which is formed by a set of walls, namely a bottom (25) intended to be fixed to the crosspiece (4), an upper wall (26), and a lower wall (22), as well as a side wall (27), advantageously has two locking grooves (19a, 19b) arranged one on the lower wall (22) and the other on the upper wall (26) , as illustrated in Figure 9. Such an arrangement makes it possible to use the base indifferently to articulate the arm (15) of the left support (6) or the arm of the right support

(7).

  According to the preferred embodiment of the support arms, the axis of rotation (16), on which the pivoting arm (15) is articulated is carried by the base (14). The arm (15) has two articulation axes (28a, 28b) capable of sliding along the axis (16) and of pivoting around the latter. Furthermore, the elastic return means (MRE) advantageously consist of a helical spring (21) disposed around the axis (16) and fixed on the latter at one of its ends (21a), while the the other end (21b) is disposed in abutment on the lower articulation point (28a) of the pivoting arm (15) in order to urge it permanently

  downwards (BA), in order to make the groove (19) and the projection (20) cooperate.

  Note that the configuration of the immobilization means (MI) advantageously makes it possible to avoid any untimely unlocking of the pivoting arm (6, 7) due to the movements of the reel (3) caused by its inertia. The unlocking of the arms can only be obtained by the voluntary action of the user: this unlocking is advantageously carried out by exerting a force on the pivoting arm (15) directed upwards (HA) against the means of elastic recalls (MRE), said force having to be exerted near the articulation of the arm (15), in order to allow the arm (15) to slide upwards (HA), so as to release the projection (20) throat (19). Note that by its construction, when the force is applied to a place distant from the joint, the support arm remains stationary. Thus, according to an alternative embodiment not shown, the pivoting arm could have gripping means such as a handle disposed on the upper edge of the pivoting arm near the articulation, in order to allow the user to stress the arm upwards (HA) sliding on its axis, said gripping means

  constituting in part the means for unlocking the device.

  I () Note that according to the preferred embodiment of the support device (2), the two support arms (6, 7) are provided with immobilization means (MI) of the type previously described. However, it goes without saying that only one of the two support arms could be immobilized in the active position by this type of immobilization means, the other arm then being completely free to pivot or locked in a slightly floating position. using a pin type system

  conventional, without departing from the scope of the invention.

  In the embodiment illustrated in Figures 1 to 9, the locking groove (19) is disposed on the base (14), while the corresponding immobilization projection (20, 20a, 20b) is formed on the arm (6, 7, 15), but it could be otherwise. Namely, the locking groove (19) could be disposed on the arm (6, 7, 15), while the corresponding projection (20, 20a, 20b) would be on the base (14), as illustrated in Figures 10a, 10b, the ramp (24), meanwhile, being produced

on the arm (6, 7, 15).

  Of course, the invention is not limited to the embodiments described and shown by way of examples, but it includes

  also all technical equivalents and their combinations.
