    application, the rotation of this application fixing screw also carries out the drag, rotation, of the compensating nut bolt.
    The known operation of said type of nuts
    6 represents that when the application screw is threaded into the hollow of the compensating nut bolt, this rotation which is dextrogirous produces, in the first place, the recoil of the compensating nut screw until it covers the entire gap existing between the panel
    12 application support and the frame or chassis of the vehicle where the compensating nut is fixed.
    The continuation of the tightening action of the application fixing screw causes, in the second place, the advance of said screw inside the screw of
    18 the compensation nut and the fixing of the application to be installed.
    EP2796729 describes a compensating nut of the type described in which the nut screw
    compensator has internal crimps formed by
    24 legs directed from the surface towards the axial axis of said screw. This nut is of complex design or because the thickness of said screw of the compensating nut is reduced, outer areas of the filleting of said screw must be sacrificed to provide material for said crimping elements.
    30 inside.
    A problem with the described solution has
    related to the deterioration of the thread of the fixing screw of the application caused by the friction of the inner, metal legs, of the bolt or compensation screw. This prevents the reuse of the set
    6 installed.
    The present invention has as its main inventive object to provide a simpler, economical and efficient means to facilitate the engagement or locking with threading capacity of the fixing screw of the
    12 application on the screw of the compensating nut, without deterioration of said screw.
    Another objective pursued by the present invention is to obtain a lighter compensation nut as a whole and a lower manufacturing cost.
    These and other advantages of the present invention will be
    more evident throughout the description of it
    which follows next.
    BRIEF DESCRIPTION OF THE INVENTION The present invention develops a compensation nut, the compensation nuts being a set consisting of screw and nut used to fix an application to a surface or panel, but maintaining a variable distance between said
    30 surface and the support or chassis where the nut is fixed, preferably used in the automobile industry, in which an overmoulding of plastic material has been made in the wall inside the hollow screw, said overmolding presenting a conical start, in its introduction opening of the fixing screw of an application, to narrow in a cylindrical body of smaller empty section than the previous one.
    6 The compensating nut is, in its preferred embodiment, metallic and in particular of treated material such as carbon steel. The part can be treated against corrosion.
    12 The nut part of the compensation nut includes, in its preferred embodiment, fixing springs to the hole or groove enabled in the fixing surface, being formed on each side, by two groups of two legs joined at its end, being aligned so that two of said legs on one side are interior,
    18 facing each other and the remaining two are exterior and act elastically against the edge of the groove, engaging. It is, thanks to the spring material thus created, carbon steel, of a tight and firm fixation that does not allow clearance with respect to the hole in the groove of the fixing surface and which
    24 adequately supports the work vibrations of the piece. This is substantially different from other fasteners of analogous use where the fasteners are substantially rigid and neither closely fit the hole nor adequately withstand vehicle vibrations.
    It should be further noted that the arrangement of the springs in the present invention, acting as
    fixing elements, aligned in groups of two on each side of the nut, allow a correct positioning of the piece.
    The nut also includes a threaded cylinder
    6 interior whose base is connected to the base surface of the nut by means of a dome-like structure that gives elasticity to the piece and a residual tension adequate to the stresses during the work of the compensation nut.
    12 For its part, the compensation nut includes a hollow screw with an upper wall from which the screw axis emerges. The filleting of said screw and that of the nut correspond to its threading, with the particularity that they are in the opposite direction to the standard. When the screw is turned clockwise,
    18 dextrógiro, the screw goes back; when turned left, levógiro, the screw advances. All for the sake of the compensatory functionality described above.
    The inner cylindrical wall of said hollow screw
    24 has downward-facing hooks and grooves. Both elements allow the plastic material to be overmoulded like a sleeve in the screw hole, to provide grip areas between the overmold and the screw that prevent any relative displacement, once the overmoulded plastic cools,
    30 shrinking in the axial direction.
    In this way, all the inventive objectives pursued have been obtained, resulting in a compensation nut that is of economic cost and of light material, since the metal parts are made from a laminar surface, by deformation and
    6 die cut, and by its same constructive disposition.

    DETAILED EXPLANATION OF THE INVENTION The present invention consists of a compensating nut, of the type of nuts forming a joint with a nut (2) and a screw (3), used to fix an application to a surface or panel but maintaining a variable distance between said
    18 surface and the support or chassis where the nut is fixed, preventing the distance from collapsing in an application fixing screw that distance,
    The nut (2) in one of the preferred embodiments of the invention is formed by a base from which 24 fasteners descend on the support surface, for example the vehicle chassis. These fasteners can be of different types and shapes. Figure 1 shows descending springs formed by pairs of legs joined at their end. These groups of pairs of legs are aligned, on each side of the nut, in a single line, thus presenting two of said legs, one of each group, as an outer leg. When said springs (4) are
    Inserted into the fixing grooves provided on the fixing surface, these outer legs act like a spring, elastically compressed against the edge of the hole.
    6 These outer legs (41) also have a recess
    or step (42) that serves as a bumper stop relative to the fixing surface. This type of construction is very favorable for the compensating nut of the invention because it allows a grip of the nut to the fixing surface without any slack and from
    12 any penetration height in the groove enabled on the fixing surface.
    In other possible embodiments of the invention, for example the one shown in Figures 3 and 4, other types of gripping elements may be used, as per
    18 example legs (5) with a descending section (51) and an ascending continuation (52) that acts flexibly against the surface of the fixing surface, by means of a surface (53)
    In the present invention, the compensation nut 1 is
    24 metal and is preferably made of carbon steel. You may have received an anti-corrosive treatment and / or include some coating such as nickel plating. The nature of the formative material of the compensation nut (1) allows the fixing of the fixing elements (4 and 5) to the groove of the
    The fixing surface is simultaneously a tight fixation, without clearances, and firm, maintaining a good elastic behavior against the vibrations of the
    vehicle, for example, and in accordance with the known technique where the substantial lack of plasticity and stiffness of its connection facilitates the disconnection with respect to the fixing support of the compensation nut
    (one) .
    6 The nut (2) has a projecting cylinder (7) with internal thread, projecting outwards in the opposite direction to the direction of the legs (5) and springs (4), with the dome being joined by a dome
    (6) or truncated conical body of circular section base and
    12 walls with a curved section. This arrangement gives elasticity and tension resistant to the nut assembly (2) against the stresses and stresses that must be suffered in its use.
    The internal filleting of the cylinder (7) is meaningful
    18 contrary to usual. So that when a screw is turned to the right in said filleting it moves away from the base of the nut, and when it is turned in a levógiro direction, to the left, it is screwed.
    The complement of this nut (2) is a screw (3) of
    24 inside forming a hollow cylinder in the axial direction, a screw that has an external filleting antagonistic of the filleting of the nut (2) to which it is threaded. As the embodiments of the figures show, this screw has an upper surface or base from which the screw shaft (3) starts.
    30 Figures 1 and 3 show the compensation nut (1) in a closed and service position, in which the height
    of the piece is minimal; that is, not fully screwed and tightened to the nut in order to allow its comfortable unscrewing, the screw (3) presenting a very small separation. In contrast, in figures 2 and 4 this same compensation nut (1)
    6 is in an unfolded position presenting a greater height, equivalent to the space to be covered between panel and chassis.
    The present invention incorporates in the cylindrical and axial recess, inside the screw (3), an overinjected, overmolded part (9), of suitable plastic material as shown in figure 6, and is visible in the detail of the figure 7, has a conical shape in the direction of the nut position (2). That is, it has a first section (12) wider in terms of the free diameter of its interior than a
    18 second section (13) of narrower inner opening.
    In order to avoid that the clearance of the fixing screw of the application in the initial conical section (12) represents that it is necessary to hold it to prevent its fall, there is a circular annular shoulder (14) in that section
    24 which elastically retains this application screw preventing its fall.
    This cone of over-injected plastic material (9) inside the screw (3) of a free section considerably smaller than that of an application fixing screw, 30 not shown, represents that this screw grips tightly in said over-injected (9) , interferes with overmolding (9), engaging in it and
    allowing the rotation of the hollow screw (3) in the nut (2). The first major section (12) of the hollow of said superinjected (9) facilitates the positioning of the application fixing screw inside the screw (3)
    6 The plastic material used is suitably hard to fulfill its function and is also flexible, like a hard rubber, because in the preferred embodiment it has been vulcanized. When the application screw enters the narrowest section of the overmold than its own
    12 metric, its filleting is pressed against the plastic interfering with said material. This allows the drag of the compensation screw (3) by the application screw. Furthermore, when the application screw of the compensation screw (3) is removed, the effectiveness for further uses of said screw of
    18 compensation (3) is maintained because the elasticity of the plastic has undergone a compression and only a partial erosion of its surface. In fact, it is known that a number of not less than ten installation and removal operations of the compensation nut according to this embodiment are possible.
    In another possible embodiment, the invention contemplates embedding a piece similar to overmolding (9), by pressure inside the screw (3). It is understood that in this case the inner surface of the screw (3) can be varied to better adapt to this embodiment, as well as the nature of the plastic material used to improve the adhesion to the screw (3). In a manner similar to the preceding case,
    Application screw works against said plastic material, by interference and not by friction, ensuring the reuse of the device.
    When the screw fixing of a
    6 application, locked the fixing screw in the superinjected (9), this rotation first produces the drag rotation of the screw (3), which expands the height of the compensation nut (1) as for example shown e Figure 2, to cover all the gap between the panel and the surface of the chassis.
    12 When the rotation of the application fixing screw can no longer expand the compensation nut (1), then the application fixing screw is produced, penetrating this screw into the hollow screw (3).
    18 The process of uninstalling the application is reverse. The levógiro turn of the application screw contracts the compensation nut (1) that once closed has no more travel in that direction, so that subsequent turns release the application fixing and
    24 remove the fixing screw of the screw hole application (3).
    This characteristic arrangement of the present invention is very convenient, since it is not only simple to manufacture, without the complex construction features of the prior art, but also provides a good grip of the application screw that allows the hollow screw to be dragged (3 ) without deteriorating said screw
    of application and thus allowing reuse
    of the parts.
    However, in order to be able to carry out this convenient solution, seemingly insurmountable difficulties have had to be overcome. As can be understood, because the rotation of the overmold (9) must be able to drag the hollow screw (3), turning it, there must be a good bond between the injected
    (9) and the hollow screw body (3). However, the technique of injecting plastic in the form of a shirt
    12 internal to the screw hole (3) presents the difficulty that the plastic, when cooled, contracts and does not expand towards the walls of the hollow screw (2), but by contracting towards the axial axis of said screw, losing connection with the same.
    18 The solution to said drawback has been to make gripping elements in the hollow interior of said screw (3) in which it was fixed to the overmold (9), wrapping or filling them. It is about creating hooks (10) on the walls inside said hollow screw (3) These hooks (10) pointing towards
    24 the position of the nut (2) preventing the outflow of the superinjected (9) outwards.
    It should be taken into account, in addition, that both the nut (2) and the hollow screw (3) are made from a sheet material, by deformation and die cutting. The piece is built as lightly as possible to take into account the qualities of the training material and the treatments it can receive,
    offer adequate mechanical behavior, according to the function you must perform.
    The walls of the hollow screw (3) are therefore the "donors" for making the hooks (10) As shown in Figure (3), this is made possible by producing a material drain in the inner wall of the screw ( 3), creating a slit (11) greater than said hooks (10). Both the slits (11) and the respective hooks (10) offer excellent anchor points for overmolding (9), so that despite
    12 of the slight shrinkage, upon cooling, of said overinjected (9), it does not lose bonding or grip in relation to the screw (3).
    The constructive nature of the composition nut
    (1) of the present invention allows during
    18 conventional installation thereof, with automatic clamping tools, perform the installation operation in a simple operation. The operator places the compensation nut in the hole to be covered and presents the application screw through the support of said application, proceeding to the screwing
    24 of the set. In practice, this is done in a single screwing operation that the operator, in the compensation nut (1) described can adjust to a high number of revolutions, even 900 rpm, possible thanks to the good performance of the piece and the interference made between said screw of
    30 application and plastic overmolding (9) that provides excellent traction grip.
    It is understood that in the present case, it is possible to vary how many details of finish and shape do not alter or modify the essence of the invention.
