Abstract: Cover platelet for joints (11) in furniture frames, the joint (11) comprising a main body (15) and connection means for tubular elements (12) of said furniture frames, the platelet consisting of a foil of a shape mating with said outer faces (15a) of the joint (11) and including lateral edges (14) folded back at an angle and able to be inserted into mating vertical grooves (16) made on the lateral surface of the main body (15).

Description: This invention concerns a cover platelet for joints as set forth in the preamble of the main claim as already disclosed in DE-A-2519607. To be more exact, the invention refers to a platelet used to cover the outer faces of joints used in assembling tubular elements which make up the frame of furniture such as tables, benches, sinks, shelves or suchlike. The joints to which the invention refers may be either angular or linear. BACKGROUND OF THE INVENTION The state of the art includes connecting joints for furniture frames comprising a main body and means to join together two or more tubular elements which constitute the legs or horizontal supports of tables, benches, desks, sinks or suchlike. The joints may be either of the angular type or of the linear type, in the second case defining the connection between two or more tubular elements joined in succession. One of the disadvantages, both functional and aesthetic, which businessmen working in this field find in the use of said joints is that the zones of discontinuity which are created in correspondence with the connection between the tubular elements and the main body of the joint, and also the outer faces of the main body, are all visible; thus there are fissures which are not only anti-aesthetic, but which also encourage the infiltration of dust, dirt, water etc. various solutions have been proposed for this shortcoming, using plates or similar, of a shape mating with the joint, with one or more pins able to slot into corresponding holes on the outer faces of the main body of the joint. These solutions however are not satisfactory, both because they do not allow to completely cover the discontinuous zones, and also because the attachment system is not completely reliable and, over time, may prove to be insufficient; moreover, they require complex and expensive working, particularly to achieve the pins on the covering plates. DE-A-2519607 discloses a right-angled platelet comprising two elastic fins able to be coupled with a snap action with two mating protrusions formed in an angular element for furniture, and therefore it has not edges angled for clamping onto grooves formed in the external surface of the joint. Furthermore, this platelet does not constitute continuity of line with the elements of the furniture because its lateral edges rest externally on the surface of the elements creating a discontinuity in the furniture as seen from the outside. US-A-3016590 discloses a decorative strip assembly consisting of a base strip sormonted by a cap assembly. This document, implicitly, discloses an element which protrudes from the external line of the furniture to which is applied to be clearly visible from outside; such strip assembly is not applied to a joint between two elements of a furniture to cover and hide the presence of the joint itself and to constitute continuity of line with the elements to which is applied. GB-A-2049863 discloses a three-dimensional joint for furniture comprising a three-dimensional cladding cap. This cap is not in the form of a foil having a shape mating with the outer faces of the joint, and has not lateral edges angled in such a way so as to be able to be inserted into grooves made on the lateral surface of the main body of the joint in order to clamp itself upon the joint. This document discloses a cap having clipping projections which enter into clipping connection with the connector body of the joint, but these clipping connection are outside to the body of the joint, so that, in order to support the cap, it is needed that the heads of the securing bolts enter into mating recesses provided in the cap. The present Applicants have devised and embodied this invention to solve all the shortcomings described above with an inexpensive, practical and extremely reliable solution, and also to obtain further advantages. SUMMARY OF THE INVENTION The invention is set forth and characterized in the main claim, while the secondary claims describe other characteristics of the invention. The purpose of the invention is to achieve a cover platelet for the outer faces of the main body of a joint connecting tubular elements in furniture, which will be practical, inexpensive, reliable, easy to make and assemble, and will hold securely over time. The invention is applied preferentially on metal joints used to connect tubular elements made of metal, but its teaching can also be extended to the case of frames and structures made partly or entirely of other materials, such as for example plastic or suchlike. The cover platelet according to the invention consists of a foil, flat or angular according to the shape of the joint to which it is applied; it has the lateral edges folded back at an angle to define attachment elements able to cooperate with mating grooves made laterally on the main body of the joint. According to the preferential embodiment of the invention, the cover platelet has or cooperates with abutment means which define the lower end-of-travel position of the platelet with respect to the joint. In this way, to assemble the platelet on the joint it is sufficient to slip on the platelet from above, inserting the folded edges of the platelet inside the grooves on the main body of the joint. The platelet is then thrust towards the bottom as far as the lower end-of-travel position defined by the abutment means. In a first embodiment, the abutment means consist of one or more fins made on the upper edge of the platelet and facing the inside, advantageously cooperating with mating hollows made in the upper face of the joint. In another embodiment, the abutment means consist of at least a protrusion made in correspondence with the lower edge of the main body of the joint. In a further embodiment, the abutment means consist of an interruption in the lower terminal part of at least one lateral edge of the platelet cooperating with a mating interruption in the relative groove on the main body of the joint. With the platelet according to the invention we therefore obtain a cover element which ensures on the one hand a simple, rapid, durable and stable assembly, and on the other hand an efficient aesthetic and functional solution, since the fissures and discontinuities between the elements of the frame and the joint are covered and closed in an optimum manner. BRIEF DESCRIPTION OF THE DRAWINGS These and other characteristics of the invention will become clear from the following description of some preferential forms of embodiment, given as a non-restrictive example, with reference to the attached drawings wherein: Fig. 1 shows a first type of cover platelet according to the invention in a condition detached from the joint; Fig. 2 shows the cover platelet from Fig. 1 when associated with the joint; Fig. 3 shows a second type of cover platelet according to the invention; Figs. 4a and 4b show two details of a variant of the cover platelet according to the invention. DETAILED DESCRIPTION OF PREFERRED EMBODIMENT With reference to the attached drawings, number 10 denotes generally the cover platelet for joints 11 according to the invention. The platelet 10 is used in association with joints 11 comprising a main body 15 and at least two insertion seatings (not visible in the drawings) in correspondence with which tubular elements 12 which make up the components of furniture frames are able to be connected. The platelet 10 is able to be associated with the outer faces 15a of the main body 15 of the joints 11 to cover holes 13, fissures, attachment elements or other anti-aesthetic parts on the main body 15. The joints 11 to which the platelet 10 can be applied may be either of the angular type, able to connect tubular elements 12 arranged at an angle (Figs. 1 and 2), or of the linear type, that is, able to connect tubular elements 12 in a line (Fig. 3). The platelet 10 according to the invention consists of a thin foil, of a shape mating with the main body 15 of the joint 11 to which it has to be associated, and with the lateral edges 14 folded back at an acute angle. The platelet 10 shown in Figs. 1 and 2 has a right-angle shape, as it has to cover the two outer faces 15a of the cubic main body 15 of an angular joint 11. The platelet 10 shown in Fig. 3 is substantially flat, since it is able to cover the outer face 15a of the main body 15 of a linear joint 11. The platelet 10 may however have different conformations, for example if the main body 15 is cylindrical or elliptic, or it may have a polygonal development if it must be able to cover several outer faces 15a of a polyhedral main body 15. According to the invention, the lateral edges 14 of the platelet 10 are able to be inserted inside mating vertical grooves 16 made on the lateral edges of the main body 15. In the embodiment shown here, the lateral edges 14 are inserted into the vertical grooves 16 from above, and the platelet 10 comprises, or cooperates with, abutment means 17 defining the lower end-of-travel position of the platelet 10 with respect to the joint 11. In the embodiment shown in Figs. 1, 2 and 3, the abutment means 17 consist of horizontal fins 18 made in correspondence with the upper edge 19 of the platelet 10 and facing towards the inside thereof. The horizontal fins 18 are able to couple with mating hollows 20 made on the upper face 15b of the main body 15, preventing the platelet 10 from going any lower with respect to the joint 11. In the embodiment shown in Figs. 4a and 4b, the abutment means 17 are defined by a lower interruption in the lateral edges 14 of the platelet 10 and by a mating interruption in the lower terminal segment of the relative vertical grooves 16 of the main body 15. In this embodiment, when the lateral edges 14 have been completely inserted, the lower profile 14a of the latter rests and abuts on the bottom 16a of the relative vertical grooves 16 (Fig. 4b), making it impossible for the platelet 10 to go any lower with respect to the joint 11. According to a variant of the invention which is not shown here, the abutment means consist of a protruding lower edge of the main body 15 on which the platelet 10 is able to rest when the lateral edges 14 have been completely inserted inside the vertical grooves 16. It is obvious however that modifications and additions may be made to the cover platelet 10 as described heretofore, but these shall remain within the field and scope of the invention. For example, instead of the horizontal fins 18 a single edge may be provided, protruding towards the inside and extending for the entire development of the outer faces 15a of the main body 15.
