The invention is described below with reference to Figures 1 to 6, which relates to a lashing system objects 1 on a support wall 2, including a support wall of a vehicle such a road, air or sea transport vehicle.

Figure 1 shows the stowage of an object in a corner of two perpendicular support walls 2. The figure represents rails 3 on which is secured an object 1 according to two embodiments represented by the respective references 6 and 16.

Figure 1 shows two support walls 2 perpendicular to each other, each comprising two parallel superimposed rails 3: an upper rail and a lower rail. The two lower rails and the two upper rails are respectively at the same height.

In Figure 2 is shown a lashing rail 3 according to the invention. This rail, made of a rigid material such as plastic or metal, is rectilinear and fixed on the wall. The rail 3 comprises a U-shaped longitudinal groove, which separates the rail into two parallel rail elements 9 located in the same plane. These two elements of rail 9, inverted U-shaped, are joined together by the base 13 of the U, that is to say the bottom of the groove, at one end of a leg of the U of each rail element 9.

The rail 3 is fixed to the wall 2 by the base 13 of the groove by any known and appropriate means. For example and preferably, the base 13 of the groove comprises a plurality of holes to allow the passage of screws for screwing the rail 3 on the support wall 2.

The flat surfaces of the rail elements 9 comprise elements in relief and are advantageously made in the form of at least partially grained surfaces. The raised elements are the support means 4 adapted to prevent slippage of the stowed object.

According to an essential characteristic of the invention, the lashing rail 3 comprises fixed securing means 5 of the object 1 in its stowed position. In the example shown, these fixed securing means 5 are bridge members, interposed between the rail members 9, transversely in the groove, and advantageously made of the same material as the lashing rail 3, preferably a piece.

The docking system also comprises, associated with each rail, a holding link 6 of the stowed object, such as a strap or a tensioner, the ends of which are connectable for example by means of a hook to transverse bridge members 5 to partially surround the object 1, the holding link 6 associated with the bridge members 5 forming a device for holding the object in its stowed position.

The lashing rail 3 may be formed in one piece. According to another embodiment, as can be seen in FIG. 1, the lashing rail 3 comprises a plurality of rail modules 7 assembled together in the longitudinal direction. Each module 7 comprises on one of its end faces centering means 8 for assembling the modules 7 in the aligned position. These centering means 8 comprise, in the example shown in FIG. 2, two L-shaped lugs protruding at the corners of the front face of a rail element 9, and adapted to engage in the corners. of the front side of the adjacent module.

Each module 7 may comprise one or more bridge members 5. That the rail 3 is formed of a part or an assembly of modules 7, the longitudinal distance separating two bridge members 5 is the same over the entire length. length of rail 3.

In addition to the bridge members 5, the invention provides at least one attachment device 10, each being mounted in the groove of the rail between two bridge members 5. Preferably, this attachment device 10 is mounted from removably, in a manner to be described later.

As seen in Figures 4a to 4c, the attachment device 10 has a parallelepipedal general shape, thus adapting to the shape of the groove of the rail. The top of the attachment device, that is to say the face that is not opposite the bottom of the groove, is shown in Figure 4a. the top face comprises a plurality of blind cavities 15, the diameters of which may be identical or different depending on the attachment devices 10, and whose axes are parallel to each other and perpendicular to the support wall 2. These cavities, or holes blinds 15 are intended to receive holding rods 16 of objects 1 in their stowed position, as shown in Figure 1. For convenience, these rods 16 are telescopic.

FIG. 4b shows the underside of the attachment device 10, and reveals two bolts 11 each mounted in the end face of the device 10. Each bolt 11 is mounted axially sliding while being guided in a cut-out in FIG. the end of the body of the attachment device 10 and a guide screw fixed in the body of the attachment device 10 and engaging in an axial groove of the bolt 11 located along the underside of said bolt 11, in the inner part of the bolt 11.

Each bolt 11 is mounted axially sliding in the device 10 at the front face, between an axially projecting output position of the end face of the attachment device 10 which allows the locking of the device 10 in the groove, and a retracted position against a return spring 12, for example a coil spring. Figures 4b and 4c also show a bolt 11 in the extended position and a bolt 11 in the retracted position.

Figures 5 and 6 show the insertion of a fastening device 10 in the groove of the lashing rail between two bridge members 5.

Figure 5 illustrates the rail 3 and the attachment device 10 before the insertion of the latter and before it is in contact with the rail 3. The length of the attachment device, when the bolts 11 are in the retracted position, corresponds substantially to the distance between two bridge members 5. Once the attachment device 10 inserted, the bolts 11 in the extended position then block the hooking device in the groove, each bolt being engaged between the bridge member 5 and the bottom of the groove 13 as can be seen in FIG.

Figure 6 shows the attachment device 10 in a position ready for insertion. The lower surface 14 of the bolt 11 facing the bridge member 5 comes into contact with the corresponding upper edge of said bridge member 5. This surface 14 has the shape of an inclined ramp and may even have a curvature, like this is visible in the figures. Thus an insertion force F, resulting from the support on the attachment device 10 to insert it into the groove, causes the displacement of the bolt 11 in its retracted position. Continued insertion of the device 10 in the groove causes the release of the bolts 11 at a time when each bolt is found below the lower edge of the corresponding bridge member 5, each then adopting an extended position and finding itself engaged. between the bottom of the groove 13 and a bridge member 5.

A user can easily disengage a hooking device 10 of the groove. It suffices to press axially on the tip of the bolts 11 to enter the attachment device 10 and make them adopt the retracted position, then gradually raise the device 10 of the groove while maintaining the support force on the bolts 11, until the latter are in abutment against the bridge members 5. It then remains for the user to grab the attachment device 10 and remove it completely from the groove of the rail 3.

Figure 1 shows the two lashing possibilities according to the invention which has just been described. In the example shown, one of the upper rails 3 comprises an attachment device 10 inserted between two bridge members 5, a telescopic rod 16 being inserted into one of the blind holes 15 of said attachment device 10 to hold the object in position. its stowage position. To maintain the object 1, in the case where there is a space between the rod 16 and the object 1 in its stowed position, a wedge 17 V is inserted between the object 1 and the rod 16, as shown in Figure 1.

A docking system according to the invention has the advantage of being simpler and faster to assemble, and enjoys great ergonomics thanks to its presentation in modules 7 and its low surface area. The lashing system also allows better retention of objects 1 in their stowed position, providing more effective protection of objects 1, especially in the context of transporting such objects. At the lower rail, the lashing can be carried out using a strap, a rope or a tensioner fixed at its ends on the bridge members 5 of the lower rails with hooks.

The configuration as described is not limited to the embodiments described above and shown in the figures. It has been given only as a non-limiting example. Multiple modifications can be made without departing from the scope of the invention. In particular, it is possible to imagine an attachment device 10 having lashing elements having the same function as the bridge members 5 of the rail 3. Such a configuration would provide close clashing elements, allowing and a finer adjustment of the lashing of the objects 1 with the aid of such a fastening device 10 and a tie-down link 6.
