    Spiral mooring device for panels.
    FIELD OF THE INVENTION
    This invention concerns a spiral mooring device for furniture panels, of which one bolt with one or several annular heads and a spiral tractor body fitted to the other panel are used in one of the panels.
    STATE OF THE PREVIOUS TECHNIQUE
    At present, and as a reference to the state of the art, the use of spiral mooring devices for furniture panels is known and known as one of the panels using a bolt with annular heads and a spiral tractor body fitted in the another panel constituted said body by means of two discs that in relation to its more or less deep location in the blind hole of the panels, are referred to as inner disc and outer disc, these spiral fillet discs are provided, which are frontally coupled to each other with separating means, and the head of the bolt constituted by annular heads.
    This same owner is the owner of Spanish Patent No. 2233167 of filing date.
    These models present in the market, have certain drawbacks. On the one hand, there is the fact that its all-metal manufacturing due to its resistance needs (usually in zamak cast iron) makes it a heavy device; to which it is increased that in order for the assembly to remain centered with respect to the panel, the disks must have different thicknesses, being a thinner one that covers only the tractive operating need and a thicker one because it serves as an eccentric tractor and spacer in the panel; which consequently entails the difficulty of manufacturing and increasing the cost of material and transport. On the other hand, given its constitution in two pieces joined by riveting; for the absorption of the transverse forces the binding axis has to be dimensioned in its very robust shape and connection and consequently with more material and weight.
    EXPLANATION OF THE INVENTION AND ADVANTAGES
    Faced with this state of affairs, the present invention refers to a spiral clamping device for furniture panels of which one bolt with annular heads and a spiral tractor body fitted in the other panel are used in one of the panels, in which The spiral tractor body comprises a plastic container housing that hugs and positions inside it two stamped discs of respective spiral dextrógira and levógira spiral seen from their opposite inner faces; stamped discs that are facing and joined together by a binding polygonal axis.
    Thanks to this configuration, it is achieved that the tensile force is entrusted to the metallic material of the stamped discs for requiring greater resistance, while the plastic housing contains a multiple mission; In the first place, it serves as a hugging hitch absorbing the transverse stresses, whereby the binding polygonal axis is partially released from them (before the absorption of stresses to the resistance of its material and the quality of the riveting was entrusted), in addition the housing provides necessary positional offset of the disks that can be reduced in thickness (in the case of the outer disk with respect to the operative embedment); and in addition the housing provides an extension of the support surface of the device in the hole that is fitted. All this makes the device assembly lighter with the use of plastic material for the housing. The discs that are now made in stamped sheet, with reduced thickness, reach sufficient strength to withstand the efforts; thus reducing production and transportation costs.

    With these modifications the set achieves a significant weight reduction that favors production and transportation costs.
    Another feature of the invention is that the plastic housing contains on its inner side some decentralizing ribs whose edge rests on the flat face of one of the stamped discs and its prominence is such that it positions the whole of the discs stamped eccentrically with respect to the plane Middle of the tractor spiral body.
    Thanks to this configuration, the required offset positioning is facilitated with respect to the middle plane of the assembly for inclusion in the panel, unlike in previous devices where the outer disk was thicker to achieve this objective. In this way the stamped discs have the same thickness also reducing the use of material and lowering costs. In addition, this configuration helps to absorb the transverse stress that the spiral tractor body suffers in the panel mooring maneuver.
    Another particular feature of the invention is that the plastic container housing, internally on the sides of the receiving orifice, has diametral ribs.
    Thanks to this configuration, the centering of the bolt head in the receiving hole is facilitated during the rotation of the set of the two stamped discs joined together by the binding polygonal axis.
    In the configuration of the inner wall of the plastic housing, the existence of pairs of lace prominences is foreseen.
    Thus, the positioning of the stamped discs and their subsequent guidance at the time of rotation with respect to the plastic container housing is facilitated by providing the discs with a double securing.
    Another feature of the invention is that each stamped disc has a reference hole indicating the beginning of its respective spiral.
    Thanks to this configuration, it is easy to assemble the stamped discs with the two spiral starts facing each other.
    Finally, another feature of the invention is that the plastic container housing incorporates an indicator transverse window that coincides with the respective reference holes detecting the correct outer and inner position of the plastic container housing and stamped discs.
    Thanks to this configuration, it is possible to visualize from the outside the reference holes of the stamped discs for the correct positioning of these and in addition said transverse indicator window serves as an orientation when correctly placing the spiral tractor body on the panel to receive the head of the bolt.

    EXHIBITION OF A PREFERRED EMBODIMENT
    With regard to the drawings and references listed above, a preferred embodiment of the object of the invention is illustrated in the attached drawings, referring to a spiral clamping device for furniture panels of which a bolt is used in one of the panels (11) with annular heads (13) and a tractor spiral body (1) embedded in the other panel, in which the tractor spiral body (1) comprises a plastic container housing (2) that hugs and positions inside each other stamped discs (3 and 4) of respective dextrógira spiral (3a) and levógira spiral (4a) (seen from their opposite inner faces); stamped discs (3 and 4) that are facing and joined together by a binding polygonal axis (5).
    Figure 1 shows the assembly of the spiral tractor body (1) in which the elements located in the coupling position can be seen. You can see the plastic housing container (2) that will be embedded in the blind hole made in one of the furniture panels. Inside it, the stamped discs (3 and 4) will be connected from the upper part by means of the binding polygonal axis (5) making the latter stop with the dextrogiro stamped disc (3) (seen from its inner facing side) thanks to the highlight (16). Once the stamped discs (3 and 4) are attached, following the coupling direction arrow (15) of the detail of Figure 1, they are inserted into the plastic housing (2) in order to be in charge of supporting the tractive force exerted by the bolt (11) located on the other panel of the piece of furniture, which by means of the application of a turning movement in the binding polygonal axis (5) through the drive window (14) will bring both panels closer together. This maneuver can be seen more clearly in Figure 2 in which the approach of the bolt (11) to the tractor spiral body (1) is shown and in Figure 3 in which a perspective of the tractor spiral body (1) is shown. with the bolt (11) inside that represents the moment of end of the approach of approach of both panels of the furniture.
    We can also observe in the detail of Figure 1 a perspective of the interior of the plastic container housing (2) in which the resistant decentralizing ribs (6) also seen in elevation in Figure 8 are observed, which are responsible for providing the necessary eccentricity to the whole of the tractor spiral body (1) with respect to its average plane. These resistant centering ribs (6) will be supported on the upper surface of the

    dextrógiro stamped disc (3) (seen from its inner facing side) thus making the stamped discs the same thickness and thus reducing the use of material and lowering costs. Furthermore, this configuration helps to absorb the transverse stress that the spiral tractor body (1) undergoes in the panel mooring maneuver.
    In the detail of Figure 1, the clamping diametral ribs (8) also seen in elevation in Figure 8 and Figure 10 are shown, these help to keep the head (12) of the bolt (11) centered in the receiving hole ( 7) during the rotation of the set of the two stamped discs (3 and 4) joined together by the binding polygonal axis (5).
    In the detail of Figure 1 and better represented in the elevation of Figure 8, the prominences of lace (10a and 10b) that guide the stamped discs (3 and 4) are observed both when fitting them into the housing plastic container (2) as at the time of rotation of the stamped discs (3 and 4) during the approach maneuver of both panels of the furniture.
    Figure 4 shows a plan view of the interior of the dextrógiro stamped disc (3) and in Figure 5 a plan view of the interior of the levógiro stamped disc (4) (seen from its opposite inner faces), in which They observe the reference holes (3b and 4b) whose mission is to facilitate the correct assembly indicating the beginning of the spirals (3a and 4a) facing each other. The correct positioning of these reference holes (3b and 4b) is visualized through the indicator transverse window (9) represented in the top plan view of Figure 7, also serving as an orientation when correctly placing the spiral body tractor (1) in the blind hole of the furniture panel.
    Variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, do not alter the essentiality of this invention, it being sufficient to proceed to its reproduction by an expert.
