    [0002] Device for fixing parts
    [0003]
    [0004] The present invention relates to a device for fixing parts, in particular, for fixing vehicle parts, for example, for fixing a bumper to a structure of the vehicle.
    [0005]
    [0006] Background of the invention
    [0007]
    [0008] During the manufacture of a vehicle it is necessary to assemble many parts, for which different fixing devices are used to fix different pieces together. For this purpose, it is usual for the two parts to be fixed to comprise respective holes in which the fixing device is placed and then tightened to make the fixing.
    [0009]
    [0010] Usually the colocation of the fixation device in its position of use is done manually and then a tool, for example, a screwdriver, is placed to perform the tightening.
    [0011]
    [0012] As is evident, this essentially manual assembly is susceptible to errors and inaccuracies, in particular, in relation to the possibility of inserting the misaligned fixing device in relation to the reference surface.
    [0013]
    [0014] In addition, this type of assembly is laborious, since it requires two actions: manual positioning and tightening.
    [0015]
    [0016] The mentioned drawbacks can be particularly delicate in the case of the assembly of some parts, for example, in the assembly of a bumper to a structure of a vehicle, since a very robust, fast and safe assembly is required.
    [0017]
    [0018] Therefore, an object of the present invention is to provide a fastener for parts that is easy and quick to install and which avoids misalignment problems.
    [0019]
    [0020] Description of the invention
    [0021]
    [0022] With the fixing device of the invention, the aforementioned drawbacks are solved, presenting other advantages that will be described below.
    [0023]
    [0024] The fastening device for parts according to the present invention comprises a fastening element that can be placed through a hole in each of the parts that are fixed to each other, and is characterized in that it also comprises a first and second fastener elements. retention, which in its fixing position, are in contact with the parts that are fixed to each other, through the fixing element said first and second retention elements and the first retention element comprising a housing for a tool.
    [0025]
    [0026] In this way, the assembly of the fixing device is quicker and simpler, avoiding further problems of misalignment, since the housing of the first retaining element allows the colocation of a tool, for example, a screwdriver, to perform the assembly and then remove the tool.
    [0027]
    [0028] According to a preferred embodiment, said housing of the first retention element is defined by at least one perimeter wall, or by a plurality of perimeter walls, each wall preferably being a curved floor.
    [0029]
    [0030] To facilitate the coupling between the first retention element and a tool, the at least one perimeter wall or each of the plurality of perimeter walls comprises a distal rim.
    [0031]
    [0032] Advantageously, said first retention element comprises a circular base, which is its mounting position is in contact with one of the parts that are fixed together, and preferably said at least one wall extends substantially perpendicular to said circular base.
    [0033]
    [0034] According to a preferred embodiment, said second retention element comprises a plurality of legs.
    [0035]
    [0036] Furthermore, the fastening device according to the present invention may also comprise a gasket disposed between the first and the second retention elements.
    [0037]
    [0038] Brief description of the drawings
    [0039] To better understand what has been exposed, some drawings are accompanied in which, schematically and only by way of non-limiting example, a practical case of realization is represented.
    [0040]
    [0041] Figures 1 to 3 are perspective views of the fixation device according to the present invention during its assembly process, in particular, Figure 1 shows the colocation moment of the device, Figure 2 shows the moment of tightening and the figure 3 shows at the time of removal of the tool.
    [0042]
    [0043] Description of a preferred embodiment
    [0044]
    [0045] As shown in the figures, the fixing device according to the present invention comprises the following components: a fixing element 1, a first retention element 2 and a second retention element 3.
    [0046]
    [0047] The fixing element 1 can be a conventional threaded element, for example a screw, a bolt or the like, which preferably comprises a head 11 provided with a complementary hole with a tool 5, which allows the clamping of said fixing element 1.
    [0048]
    [0049] Said tool 5 has a shape such that it allows its insertion in the first retention element 2 before its assembly in the holes 6. Moreover, once the pieces 7, 8 have been firmly joined by the rotation of the fixing element 1, the tool 5 allows its release from the first retention element 2 with a small external effort.
    [0050]
    [0051] This fixing element 1 passes through holes 6 of the pieces 7, 8 to be joined together. For example, the pieces may be a structure 7 of a veticle and a bumper 8, or any other similar pieces.
    [0052]
    [0053] The first retention element 2, in its mounting position (figures 2 and 3) is in contact with one of said parts 8, and comprises a housing for the positioning of the tool 5, for example, a screwdriver, to facilitate the tightening of the fixation element 1.
    [0054]
    [0055] According to the embodiment shown, the first retention element comprises a circular base 21, from which a plurality of perimeter walls 22, which advantageously have a curved plan, extend substantially perpendicularly.
    [0056] To facilitate the retention of the tool, each of said perimeter walls 22 comprises a distal flange 23, which is preferably fitted inside a slot 51 of the tool 5, as can be seen in figure 2.
    [0057]
    [0058] It should be noted, however, that the housing of the first retention element 2 can be defined by only a perimeter wall 21, although in this case the material of said perimeter wall 21 must be sufficiently elastic to allow the accommodation and removal of the tool 5. Occasionally, the slot 51 may be placed in the piece 2 and the flange 23 in the tool 5.
    [0059]
    [0060] For its part, the second retention element 3, in its mounting position, shown in Figures 2 and 3, is in contact with the other part 7, and in accordance with the represented embodiment, comprises a plurality of legs 31.
    [0061]
    [0062] The fixing device according to the present invention also advantageously comprises a joint 4, which in its mounting position is placed between the first 2 and the second 3 retaining elements.
    [0063]
    [0064] The operation of the fixing device according to the present invention is as follows:
    [0065]
    [0066] Firstly, with the tool 5 placed in the housing of the first retention element 2 and coupled with the fixing element 1 through its head 21, the fixing device is placed in its use position, passing through the holes 6 of the parts 7, 8, for example, a structure of a vehicle and a bumper (figure 1).
    [0067]
    [0068] To facilitate collocation, the tool 5 is retained inside the housing thanks to the presence of the flange 23 on the perimeter walls 22 of the first retention element 2, which are housed in a slot 51 of said tool 5.
    [0069]
    [0070] By placing the fixing device in this way its alignment with respect to the parts 7, 8 is guaranteed. For this, it is also possible that the legs 31 of the second retaining element 3 define a polygon, whose shape coincides with the shape of the holes 6, so that only the legs 31 will be introduced into said holes 6 if the insertion is performed in a substantially perpendicular manner.
    [0071] Once the fixing device is placed in its position (Figure 2), the clamping element 1 is tightened, so that the first and second retention elements 2, 3 contact both parts 7, 8 in a sufficiently tight manner to guarantee the correct fixation.
    [0072]
    [0073] This tightening is done by turning the fixing element 1 in the proper direction. This rotation will cause the movement of the fixing element inside both retention elements 2, 3.
    [0074]
    [0075] Once the tightening has been carried out, the tool 5 is removed, which can be carried out easily thanks to the elastic nature of the perimeter walls 22 defining the housing of the first retention element 2.
    [0076]
    [0077] Although reference has been made to a specific embodiment of the invention, it is obvious to a person skilled in the art that the described fixing device is susceptible of numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalents, without departing from the scope of protection defined by the appended claims.
