SYSTEM FOR FIXING ACCESSORIES TO PANELS AND/OR SELF-CARRIER ELEMENTS FOR THE INTERNAL LINING OF VEHICLES

Abstract: The fixing system comprises a staple (1) and a pin (15) which is previously fixed to the corresponding accessory (13) to be connected to the staple (1) in order to form an integral assembly to be fixed to the corresponding panel or self-carrier element. The staple (1) has a window (14) at its base through which the pin (15) can be passed through and remains fixed by means of facing and upper edges (11) to which the sides (8) of the staple itself (1) are connected: thereby, it is possible to mount by insertion and clipping of the pin (15) through the staple (1) the integral assembly formed by the staple, the pin and the accessory to the corresponding body of the vehicle in a direct way and without screws. The dismounting can be effected very easily by means of an appropriate tool which is rotationally actuated in order to separate the upper edges (11) and to separate the staple from the pin thereby dismounting the assembly.

Description: OBJECT OF THE INVENTION The invention relates to a system for fixing accessories to self-supporting panels or other elements lining the interior of motor vehicles. The object of the invention is for fixing to take place directly, simply and efficiently, without having to use such additional elements as the classic screws required by conventional fixing systems. The object of the invention is also to enable the accessory to be easily dismounted or detached from the integral assembly it forms part of, which dismounting may be effected using a conventional implement and without any problems whatsoever. BACKGROUND OF THE INVENTION In mounting self-supporting elements or panels to which certain vehicle accessories or mechanisms are fixed, such as grips in the cabin interior, armrests, rear-view mirror, etc., and in order thereon to mount the entire assembly on and have the same held to the actual vehicle bodywork, clips are used which are on the one hand the means fixing the accessory to the respective self-supporting panel and on the other the means fixing said assembly to the vehicle bodywork. In particular, Spanish Patent no. 9401338 and Certificate of Addition thereto no. 9501623 disclose a clip for such mounting and fixing purposes, the clip being a metal clip consisting of a steel strip having a flat base and two end expansions, and moreover having two symmetrically folded side projections, which projections are each fitted with flexing flaps diverging outwards. The clip disclosed in these documents is peculiar in a number of ways, namely for instance because the end expansions of the base define four corners which allow the clip base as such to be full stably supported, even if the window provided in the vehicle bodywork for it to be fitted is longer than the minimum required, the extensions or expansions being provided with a slightly inclined plane for an easier locking and fixing of the clip in and to the relevant window. Furthermore, said base has two holes, provided with a straight section close to the side or end edges of the clip base, which holes help properly insert the respective positioning guides purposely provided on the accessories to be fixed, moreover making it easier to insert in and subsequently centre the clip proper on the vehicle bodywork window, upon the clip sliding along the inclined and vertical planes which the bases supporting the accessories are purposely provided with. The subject clip is also peculiar in that the side projections are bent into a rounded shape at their top and extend into vertical sections which come to lie side by side and projecting perpendicularly relative to the base, provided to endure the stress conveyed from said base of the clip when the accessory is arranged thereon. This type of clip has a number of drawbacks or disadvantages, such as the fact that screws and washers are required to fix the clip to the accessory, which results on the one hand in a waste of time due to the screwing operation, and on the other the disadvantage that arises at times when effecting such screwing operation, due to the structural characteristics of the accessory as such and the other component parts involved in the locking or fixing operation. The US patent nº 3.374.979 describes a fastener which comprises a pair of arms having inwardly turned ends to receive a tab member, which may be struck to a metallic chassis. The fastener is meant for electrically grounding and mechanically fastening a period circuit board to a chassis. This fastener is not suitable to withstand the large stresses involved in fastening internal vehicle ceiling accessories. DESCRIPTION OF THE INVENTION The fixing system disclosed herein has been devised to solve the above-mentioned drawbacks and moreover provide a number of innovations which result in substantial advantages and new benefits. The fixing system subject of the invention comprises the features of claim 1. Connection between the accessory and the clip by means of the plastic material peg can be made directly simply by pressing, using the thumbs, or by means of a purposely made implement, if this is to take place automatically. The plastic material peg eliminates the classic screw and washer used in conventional systems. Clearly, the new fixing system will eliminate any difficulty whatsoever in regard to screwing to fix the peg and clip and accessory, for there is no screw whatsoever in this case, hence the savings in both time and materials, etc. Furthermore, because of the special peg configuration, the use of the peg as the interconnection element or to fix the clip and the accessory to each other results in the peg lying on top edges or ridges of the clip flaps or tabs through which support is provided on the edge of the window purposely made in the bodywork, this new arrangement allowing for a substantial rigidity and making the assembly far stronger, indeed as regards "feeling" towards heavy loads, unlike conventional fixing systems, in which a screw is fixed on the actual clip base, which base is the weakest element in the clip because of its configuration, and is however the portion or element undergoing a greater pull/bending stress, thereby conveying a "feeling" of scarce rigidity to strong pulling forces. As for the clip structure, not only does it have the base and its end and side expansions, as well as flexing flaps and the relevant sides, as with conventional clips, but it is particular in that the side flaps of said clip, are not folded on themselves after their rounded top bend to define vertical side by side expansions, but are rather interrupted after the rounded bend to define a spacing between edges for the relevant connection to the respective peg, being also particular in that the base of said clip has a large rectangular window to allow said peg through. For its part, said peg consists of a body with a lower rectangular base and a small double slot keyway coaxial with the peg axis, a narrow part with a large hole projecting from such base and ending at the top in a rounded shape resulting in a T-shaped cross-section the cross or top leg of which is entirely rounded, as noted before, i.e. hemispherical or the like, whereas a stepping is defined beneath same on either side precisely for the top edges of the sides of the actual metal clip to be positioned. Now, therefore, if it should be necessary to dismount any accessory or all the accessories fitted on the self-supporting panel or in other applications, a simple manual implement in the form of a two-part wrench will be inserted through the small double slot keyway coaxial with the peg axis, and upon pushing and turning it over 90°, the top edges of the sides of the actual clip will be appropriately drawn away from the stepping or supporting side portion on the peg where they are inserted, being released therefrom and hence from the fixed position, said clip being in principle fixed to the bodywork window from which it may be readily removed by acting on its tabs with a simple narrow blade screwdriver, to restore it once again by inserting it in the relevant peg of the removed accessory, or leaving it in position and inserting in it again the peg of the dismounted or replaced accessory, whereupon it will be perfectly fixed without any further operations being required. Because the top edges of the sides of the clip are not in contact with each other, but are rather supported on the sides of the peg body, all squeaking which might result upon their rubbing against each other when the accessory is manipulated or due to the actual vibration of the bodywork or movement of the vehicle will be avoided. The subject fixing and locking system results in the elements being efficiently clipped, enhancing and further securing their insertion in elongate bodywork windows, their rigidity remaining unchanged, which is an important condition when the dispersion of tolerances with respect to the reference points established as a result of the welding processes of the car bodywork elements must be offset. The peg has characteristics that allow the clip and the peg to be dismounted or detached from one another by means of a conventional implement, such as a screwdriver, to which end the hole through which the tool or implement proper is inserted is provided to extend into a tubular extension that reaches the top end of the actual peg, a bore being defined between said edge and the end of the tubular extension, to allow the implement through in order that it may drive the clip, simply making a sharp 90° turn. The top edge of the bore through which the expander implement can operate has a central cylindrical recess with two abutments, the latter delimiting the maximum rotation of the implement in order to draw away the edges of the flexing flaps and thereby release the clip from the peg, for a quarter of a turn in turning the implement or screwdriver allows such expansion or drawing of the flexing flaps of the clip and thus its disconnection from the peg. The tubular extension provided as an improvement in the embodiment described for the inventive peg allows the implement or screwdriver to be inserted duly guided in the right direction toward the central cylindrical recess with which the top edge of the window through which the implement can act is purposely provided. For its part, the clip is particular in that its flexing flaps can be provided with lightening windows, thereby improving flexibility and making it easier to insert the clip in the bodywork receiving windows. Specifically, one of the advantages of this embodiment lies in that the window provided on the bottom base of the clip to allow the peg through is eliminated centrally, resulting in the same being reduced to two facing incuts on its base, which will now allow a development to be had with sufficient material for the side flexing flaps to be longer, which greater length will be used to obtain expansions therein, which are divergent and on which it is sufficient to act using pincers or pliers once the peg has been removed to detach the clip from its anchorage. This improvement moreover means that the indents purposely provided in the side flaps for them to be fixed to or anchored in the edges of the window purposely provided in the vehicle bodywork will lie in a lower relative position, which allows the inlaying which previously had to be made around the bodywork anchorage window to offset the height or distance between those indents and the top base of the clip to be eliminated. Clearly, the new conception or improvement referred to allows said distance to be controlled in the clip manufacturing process, as the thickness of the shell where the relevant window is to be made may require to be applied. Another improvement lies in that the clip base is provided with small flaps, as an integral part of the end and side extensions, which flaps allow the accessory or mechanism to be held, allowing part of such end extensions to be eliminated, where this is deemed convenient, which operation would take place during the manufacturing process, which would result in the clip base being considerably reduced, which might be interesting for certain applications in which the condition that the clip have the end and side extensions may not be required. Furthermore, another improvement provided lies in that the end extensions of the clip base are provided with small deformations or depressions which allow clipping to be secured after moving the clip itself in the insertion action in the relevant window. Another improvement lies in that the top facing edges of the clip sides have small central protuberances and a small arch between them, in order that upon being opened or moved by a screwdriver action, in the operation to release the peg, the arch may lie in a stable position and make the operation easier, allowing the screwdriver to be turned to the right or to the left, unlike former versions in which the screwdriver could only be turned in one direction, moreover allowing the abutments required in the inner conformation of the peg in the preceding version to be eliminated. Another improvement of the invention lies in providing the peg with ribs or reinforcements which, in addition to providing the peg with greater stability, serve to guide the clip and manage to centre the same on the window, enabling support on all four sides, rather than on the two broadsides as before. Another improvement lies in that the peg proper is provided with depressions which allow the clip deformations to be housed during the overtravel required for clipping between the latter, the peg proper and insertion thereof in the bodywork window. It is also an improvement of the invention to provide the peg with other depressions allowing movement of the divergent clip extensions whilst both parts are being coupled, and their insertion in the window. In a further embodiment, the clip can be a double clip, i.e. made up of two like elements connected by a pair of intermediate sectors or arches, albeit provided collaterally with the two clips, which sectors or arches are obtained as an integral part of the actual development of said double clip. Clearly, the peg to be used with this clip can also be a double peg and will comprise respective identical bodies, provided on a single base and with a passage that will come to lie facing the passage defined between the two clips and bridges connecting the same, in order to allow the passage of a supporting turret, namely for instance the base of a sunshade. The facing parts of the two pegs will have pairs of ledges on and against which the respective lower sectors of the flexing flaps for the two clips will be supported and abut, in order to achieve a suitable anchorage and attachment therebetween.

PREFERRED EMBODIMENT OF THE INVENTION With reference to figures 1 to 5, the fixing system subject of the invention first of all comprises a metal clip (1) provided with a flat base leading into end extensions (2) having side expansions (3), the latter being slightly inclined upwards, at an angle a to the horizontal plane of the base. The purpose of these side expansions (3) is for the clip as a whole to be full stably supported and for the clip (1) to be perfectly locked and fixed to the respective window (4) purposely provided in the vehicle bodywork, even if the length of this window is greater than the acceptable minimum. This clip (1) is provided with trapezium-shaped flexing flaps (5) on its sides, diverging downwards from the top until they reach a point at which they are provided with a rounded bend (6) and then continue into inclined sections projecting downwards and inwards, said sections being externally provided with a longitudinal indent (7) the purpose of which is to avoid the actual clip (1) from sliding on the relevant edge of the window (4), thereby ensuring that it is locked and very substantially enhancing the resistance to the stress derived from such an action. The flexing flaps (5) aforesaid are made on the sides of the actual clip, defining in the latter sectors (8) with an almost vertical lower section (9), whereas the actual sectors (8) converge upwards until they reach a point at which they are provided with a rounded bend defining a top section (10) in each sector (8), ending in facing edges (11). In other words, the rounded sections (10) after the top bend lie with their edges facing and with a spacing, which sections run parallel to the actual base. The sectors (8) are provided at their top outer end edges with respective tapers (12) assisting in the clip as a whole being inserted through the relevant window (4). For their part, since they are trapezium-shaped, the flexing flaps (5) allow a better balance of ratios to be achieved on the edges or top area thereof, and therefore with the inclination of such flaps and of the sectors (8) proper, a sort of top frustum-of-the-pyramid is formed that makes it easier for the clip to face and be inserted in the relevant window (4). The vertical lower section (9) of the sectors (8) provides for guidance and centring of the clip within the window (4), thereby ensuring a relative positioning of the relevant accessory (13) that is to be fixed, even if the latter is simple or unitary, since turning is thereby avoided. The actual clip (I) is provided with a large broad rectangular window (14) centred longitudinally on its base, through which the relevant peg (15) will be inserted as a fixing element between the actual clip (1) and the accessory (13). Said clip shown in figure 2 consists of a body with a rectangular base (16) from which a part (17), that is likewise rectangular in shape, albeit rather smaller, projects vertically upwards, with a lower section (18) having vertical rectangular sides, from which the part (17) projects forming a T-shaped cross-section with a top convexly curved part (19), which could be said to have a semicircular profile, beneath which a stepping (20) is defined at a right angle to the respective core (21) of the T-shaped configuration of said top portion of the peg (15) proper. The sides of said peg (16) are trapezium-shaped with the exception of a lower section which is straight, before reaching the lower section (18), said peg (15) being provided with a large window (22) the purpose of which shall be explained hereinafter. The trapezium sides of said peg (15) converge upwards, i.e. in an inclined manner, until they are connected at the top by said rounded or semicircular configuration (19). Furthermore, said peg (15) has a double slot (23) or keyway coaxial with its axis. In accordance with these characteristics, the peg (15) is inserted through its top semicircular portion (19) through the window (14) on the base of the actual clip (1), flexing the sectors (8), until the facing edges (11) of these sectors (8) lie beneath the step (20) on the peg, supported on the sides of the rib or core (21) thereof, thereby avoiding potential squeaking due to vibration of the bodywork proper or strange manipulations of the mechanisms, for they all make up a solid assembly which provide for a very strong fixing of the accessory (13). Clearly, along with the rounded surface or top semicircular edge (19) of the peg (15), the tapers (12) of the sectors (8) make it easier to insert the peg through the actual window (14), this insertion and final anchorage or fixing being moreover assisted by the trapezium shape and inclined edges of the sides of the actual peg (15) which, if an accessory (13) must be dismounted using a special implement (24) as shown in figure 5, with an upper crescent-shaped head (25), can be very easily made, for it will be sufficient to insert such an implement (24) with its head (25) through the double slot (23) thereafter to turn the former and move it by pushing in an axial direction, the peg (15) window (22) actually allowing the head (25) of the actual implement (24) to be turned, thereby allowing the facing edges (11) of the clip (1) to be detached or released from the actual peg (15). In an alternative embodiment, or in other words improvements both in the clip (1) and the peg (15), as shown in figures 6 to 11, the flexing flaps (5) are shown provided with lightening windows (5'), which improve the flexibility of these flexing flaps (5) and make the clip (1) easier to insert in the respective windows. For its part, the peg (15) made with the improvements shown in figures 6, 7, 8, 10 and 11, is particular in that the top has a triangular profile (19') and is provided on the bottom with a bore (26) from which a tubular extension (27) projects almost up to the top edge of the peg, a window being defined between said edge and the ending of the tubular extension (27), which top edge is provided with a central cylindrical recess (29) and a pair of abutments (30) the purpose of which shall be described hereinafter. In accordance with these characteristics, the peg (15) is inserted, through its triangular-shaped top (19'), in the window (14) on the base of the clip (1), causing the sectors (8) to flex until the facing edges (11) of said sectors, or in other words the flexing flaps (5), lie beneath the step (20) of the peg (15), supported on the sides of the rib or core (21) thereof, with the above-mentioned benefits and advantages. The new characteristics of the peg (15) allow the assembly to be dismounted easily using a conventional implement (31), such as a screwdriver, which is inserted in and guided through the tubular expansion (27), reaching the central cylindrical recess (29) provided on the top edge of the window (28), and therefore by inserting said implement (31) as shown in figure 10, once the position shown is reached, it is turned clockwise one-quarter of a turn, such turn being limited precisely by the abutments (30), which turn draws away the edges (11) of the clip sides, thereby for the clip to be detached or released from the peg and hence for the assembly to be dismounted. In the alternative embodiment shown in figures 12 to 15, it may be seen that the clip (1) has no central window, the same being reduced to a pair of facing incuts (32), which allows a development to be had with sufficient material in order for the flexing flaps (5) to be larger, both in length and width, and consequently be able to provide the latter with expansions (33), facing and lying at a suitable divergent angle to each other, in order that whenever the clip (1) has to be removed, it will be sufficient, once the peg (15) has been removed, to draw these expansions (33) towards each other using pincers or pliers in order to full easily release the clip. Said greater development of the flexible or flexing flaps (5) allows the indents (7) for fixing to the edges of the window (4) to lie at a lesser height, in their relative position, thereby to be able to eliminate the inlaying which had to be made around the bodywork window (4) to anchor the assembly, which inlaying was made to offset the height or distance between the indents (7) and the top base of the clip, whereas with this embodiment, due to the greater development of the flexing flaps (5), the distance can be controlled in the clip manufacturing process and said inlaying can be eliminated. In addition to the novel characteristics of this third embodiment, the clip (1) has four small flaps (34) as an integral part of the flaps (3), which flaps (34) allow the extensions or expansions (3) to be cut along lines (35) shown in figure 12, for based on these flaps (34), the clip (1) is able to fulfil its purpose perfectly, in which case its base is reduced, which may be interesting for certain applications in which these end extensions or expansions (3) may not be necessary. Another novelty of the embodiment being described lies in that the clip (1) is provided, at the start of the flaps (3-34), with certain conformations or deformations (36) which secure clipping during the insertion operation in the respective window, since overtravel may be had. Another novelty of this alternative embodiment lies in that the facing edges (11) of the sectors (8) of the clip (1) are provided with pairs of small protuberances (37), facing each other, and provided with an arcuate notch (38), the foregoing in order to allow, during the opening operation using a suitable implement, that the latter's end be in a stable position, the opening operation being made easier by the edges (11). This characteristic avoids having to include the abutments limiting rotation of said opening implement in order to unlock the peg and the clip, thereby allowing said implement to turn both to the right and to the left. As for the peg (15), in this third embodiment being described, its essential novelty lies in being provided with reinforcement ribs (39) which, in addition to providing it with greater stability, serve as a guide means for the clip (1), centring the same on the respective window, through the longer sides, and moreover achieving a support on all four sides, which provides a greater rigidity in mounting the actual peg. The ribs (39) have extensions (40) at their base, the purpose of which is to provide the assembly with support and stability, upon being inserted in the bodywork window (4). Furthermore, the base (16) of said peg (15) has depressions (41) at the sides, which allow the deformations (36) of the clip (1) flaps to be housed, making clipping on the window easier, and moreover has other intermediate depressions (42) which allow the expansions (33) of flaps (5) to be moved in the same operation. In accordance with the above-mentioned characteristics, mounting takes place by inserting the peg (15) solidly attached to the accessory (13) through the window purposely provided in the relevant self-supporting element (43) shown in figure 16, the accessory (13) abutting against the lower base of said self-supporting element, the peg (15) passing through its window and thereafter being clipped onto the clip (1), which lies over the opposite face of said self-supporting element (43), thereby to form a peg-clip-accessory-self-supporting element assembly, suitable to be fixed to and anchored in the bodywork window (4). Based upon said characteristics, a metal-plastic clipping system is obtained between the metal clip (1) and the plastic peg (15), which is particular in that due to the configuration characteristics of the peg, once the peg (15) has been detached or released, since the expansions (33) are compressed between each other, it is possible to full easily remove said clip from its housing. Similarly, due to the new size of the flexing flaps (5) of the clip (1), the indents supporting the same can be at such a distance from the base as to allow their being mounted on windows (4) without any inlaying. Another advantage lies in that due to the arcuate notches (38) on the facing edges (11), which notches are provided between the facing protuberances (37), the implement can be kept in the opening position throughout the operation to detach the peg (15) from the clip (1). It is also noteworthy that the flaps (34), which allow the end extensions (3) to be rendered independent through the lines (35) of the clip (1), allow the clip base to be reduced and hence to provide it with another application. In another embodiment, the clip is a double clip, as shown in figure 16, and may indeed be a triple clip, which double clip includes two identical elements or units (1) lying correlatively between each other and connected by a pair of side end outer arches or sectors (44), a passage (45) being defined between them. These two elements or clips (1) have the same characteristics as the clip (1) described in the preceding figures, and are arranged as shown in figure 16 correlatively with respect to each other, in a symmetrical arrangement, and therefore the side intermediate connecting sectors or arches (44) are obtained as an integral part of the actual development of said double clip (1). The double peg (15) will be double as shown in figure 17, i.e. will have two identical units as described and referred to hereinbefore, both emerging from the same base (16), with the same components as before, and a passage on said base (16) for a supporting turret (46) provided on the arm (47) of an accessory, namely for instance a sunshade or the like, which turret (46) will also pass through the opening or passage (45) defined between the two clips (1) of figure 16. In addition to the above-mentioned characteristics, the peg (15) forming a single assembly as shown in figure 17 will have a pair of ledges (48) on each side, defining the same number of abutments to support the lower ends (9) of the flexing flaps (5), allowing the latter to provide the required effect. Together with the double peg, said double clip makes up an assembly which may serve as an element for fixing special accessories, such as sunshades for instance.

A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in claim 7, characterised in that the expansions (33) diverge outwards, which allows them to be drawn towards each other by means of pincers or pliers, once the peg (15) has been released from the clip (1). A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in claim 7 and 8, characterised in that the sides of the clip (1) base include, before the end extensions (3), four flaps (34) which allow said end extensions (3) to be rendered independent by cutting, during the manufacturing process, along transverse lines (35), thereby reducing the size of the clip (1) base. A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in claim 7 to 9, characterised in that small deformations (36) are provided before the flaps (34) with which to achieve a more secure clipping of the clip (1) to the peg (15) and insertion thereof in the window (4) due to overtravel. A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in claims 7 to 10, characterised in that the facing edges (11) of the clip (1) are in each case provided with a pair of protuberances (37) and between them with a sector shaped as a small arcuate notch (38) which, upon being opened or displaced by action of an implement, such as a screwdriver, in the operation to detach the peg (15), allows said implement to be kept in a stable position making the detachment or releasing operation easier, and further allowing the very implement to be turned in both directions. A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in claims 7 to 11, characterised in that the peg (15) has reinforcement ribs (39) which provide the actual peg with greater stability and rigidity, constituting a guiding means for the clip (1) upon being inserted through the window (4) of the vehicle bodywork, defining a direct support of the peg (15) against the window, through all four sides of the peg. A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in claim 12, characterised in that the reinforcement ribs (39) of the peg (15) are provided with expansions (40) which enhance the support and stability of the peg-clip assembly upon being inserted in the respective window (4) of the vehicle bodywork. A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in claims 7 to 13, characterised in that the base (16) of the peg (15) has side end depressions (41) for location of the respective deformations (36) on the clip (1), said peg (15) having central depressions (42) which allow the expansions (33) on the flexing flaps (5) of the clip (1) to be moved in the same clipping operation between the clip and the peg and the assembly to the bodywork (4') window (4). A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in preceding claims, characterised in that the clip (1) is a double clip and is defined by two identical units connected by means of side sectors or arches (44) provided between the same, as an integral part of its own development, a passage (45) being defined between the two clips (1) and the interconnecting sectors or arches (44), which allows the passage of a possible turret (33) purposely provided between the double peg (15) with two identical units emerging from the same common base (16), namely for instance a support or turret (46) belonging on an arm (47) of a conventional accessory, such as a sunshade for instance. A system for fixing accessories to self-supporting panels and/or elements lining the interior of vehicles, as in claim 15, characterised in that each of the two double peg units (15) are provided on their facing side faces with respective ledges (48) that define abutments for supporting the respective lower sections (9) of the flexing flaps (5).
