    专利说明:
    [0001] The present invention relates to a system for fastening a fender to tubes installed in the frame of a vehicle, and in particular the frame of trucks, TIR and other heavy vehicles, which allows a safe and at the same time rapid fixing for those fender models without a cylindrical housing for fastening to tubes integral to the truck frame. At the state of the art, there are known various embodiments of devices for fixing fenders to truck frames and similar vehicles. Some categories of fenders are provided with a cylindrical housing configured to receive a tube integral to the frame. The axial sliding of the fender to the tube is limited by means of blocking means. These devices are engaged in the tube and fender housing and fasten the two pieces relative axial position. Anyway, some fender models are not provided with a cylindrical housing configured to receive a tube integral to the frame, and so the problem to provide a coupling device which allows a rapid and safe fixing to the frame of a vehicle, also for these devices, remains unsolved. Aim of the invention
    [0002] Aim of the present invention is to provide a fastening system of a fender to a frame of a truck, which overcomes the limits linked to the devices known according to the state of the art, and which can be applied to those fenders not provided with suitable housings for fastening to tubes integral to the frame. Moreover, the invention provides a rapid coupling/decoupling system which can be rapidly mounted and able to guarantee the anchorage of the fender to the tube integral to the vehicle frame also in case of strokes. Brief description of the invention
    [0003] The invention reaches the prefixed aims since it is a device (1) for fastening a fender to a hollow tube (30) integral to a frame of a heavy vehicle, comprising: a plastic insert (20) configured to be introduced in said hollow tube (30) integral to the frame of a vehicle, a first fastening means (10) configured to be fastened both to said insert (20) and the fender (40), and a second fastening means (60) configured to be fastened to the fender (40) and comprising a through hole for said tube (30). Description of the rapid coupling/decoupling functioning
    [0004] The invention will be described in the following with reference to the appended figures 1 to 10.
    [0005] In figure 1 and 2 there are shown two section views of the fastening of the first fastening means (10) to the tube integral to the frame; in figures 3, 4 and 5 there are shown axonometric views of said first fastening means; in figures 6 and 7 there are shown axonometric views of said second fastening means; in figures 8, 9 and 10 it is shown the assembly of the devices to the fender.
    [0006] The device (1) according to the invention comprises a plastic insert (20) configured to be introduced in a hollow tube (30) integral to the frame of a vehicle, a first fastening means configured to be fastened both to said insert (20) and the fender (40) and a second fastening means configured to be fastened to the fender (40) and comprising a through hole for said tube (30). The substantially cylindrical plastic insert (20) comprises an abutting surface (21) and at least a snap hook (22). The insert is configured so that by introducing it inside a tube (30), the snap hook (22) engages a suitable hole (31) provided in the tube (30), and the abutting surface is stopped against the end portion (32) of the tube (30), thus fastening the axial sliding of the insert (20) to the tube (30). The provision of at least one, and preferably more than one snap hook (22) fastens also the relative rotation between insert (20) and tube (30). The projecting portion (24) of the insert is also provided with an outer abutting surface (25).
    [0007] In the portion (24) remaining projecting with respect to the tube (30), the insert (20) comprises also at least one, and preferably more than one wedge hook (23) configured to engage an abutting surface (13) provided in a suitable housing (11) of the fastening means (10).
    [0008] The fastening means (10) comprises in fact a cylindrical housing (11) provided with a first (12) and a second abutting surface (13). The housing and the abutting surfaces are configured so that, when the projecting portion (24) of the insert (20) is introduced in said housing (11), the first abutting surface (12) is stopped against the outer abutting surface (25) of said insert (20), and the second abutting surface (13) is engaged by said at least one wedge hook (23), thus fastening in both directions the relative axial sliding of the fastening means (10) to the insert (20) and so to the tube (30).
    [0009] Moreover, conveniently, the fastening means (10) comprises also a second housing (14), of greater dimensions, configured to be coupled with the tube (30), when the first cylindrical housing (11) is coupled with the projecting portion (24) of the insert (20) in the just described way.
    [0010] The fastening means (10) comprises also a body (15) provided with suitable seats (16, 17) for fastening the same to a fender by means of bolts and nuts, as well as a hole (18) in the side wall of said body (15), configured so that the introducing of a tool is allowed for releasing the device by means of pressure on the projecting portion (24) of the insert (20).
    [0011] In figure 5, it is shown an exploded view of an embodiment of the bolts and nuts which can be used for anchoring the fastening means (10) to a fender, useful in case said seats (16, 17) are provided with a rectangular slot open from one side. In this case, the bolts and nuts comprise for each one of the two seats (16, 17) a screw with round head and square shaft (50), a square washer (51), a round washer (52) and a self-locking nut (53).
    [0012] As it is shown in figures 6 and 7, the system comprises also a second fastening means (60) configured to act as passage for the tube (30) and to be fastened to the fender (40) similarly to what happens with the first fastening means (10), according to what shown in figures 9 and 10. Also said second fastening means (60) comprises a cylindrical housing (61), in which the tube (30) integral to the frame can be introduced slidingly, and comprises two seats (66, 67) for fastening the same to a fender by means of bolts and nuts, similarly to what happens for said first fastening means (10).
    [0013] In figures 8 to 10, it is shown the functioning of the device. Fig. 8 is an exploded view of the various elements of the system as well as of the bolts and nuts. The next figures 9 and 10 highlight the axial sliding of the fender (40) to which the two fastening means (10, 60) are previously fastened. At first, as it is shown in figure 9, the tube (30), to which the insert (20) is previously blocked, engages the second fastening means (60), and in the following it engages the first fastening means (10), where it is introduced until the insert (20) engages the relative abutting surfaces by means of its own hooks, as just described.
    [0014] It is to be specified that the device according to the present invention can be mounted in any position with respect to the development of the fender.
