    [0002] Frame structure of a piece of furniture
    [0004] The present invention relates to a frame structure for a piece of furniture of the type comprising struts and crossbars joined in a grid-like configuration.
    [0006] In the field of furniture, it is known to use metal tubes to produce frame structures intended to be used in pieces of furniture of different types.
    [0008] For example, the German utility model DE 202008015827 reveals a piece of furniture that has a structure formed by a series of tubes that are joined by a connecting element that receives the end thereof.
    [0010] However, the need to provide a specific connecting element between the various components makes the assembly complex and requires additional components, which inevitably increase production costs and require adequate storage.
    [0012] Another solution is described in document US 1,473,817 which refers to a frame for furniture pieces comprising struts and cross members that are joined by means of an interlocking system formed by tabs that can be inserted into the respective seats that are present on the strut and on the crossbar, respectively.
    [0014] Although this solution is structurally simpler than the previous one, it is less stable and can be inadvertently decoupled.
    [0016] Furthermore, if it were desirable to provide a more stable interlocking joint that offers a greater interference fit between tongues and seats, this would inevitably make the assembly more complex.
    [0018] Therefore, the technical problem addressed by the present invention is to provide a frame structure for pieces of furniture that allows to overcome one or more of the disadvantages mentioned above with reference to the prior art.
    [0019] This problem is solved by the frame structure of furniture pieces according to claim 1. The present invention has several relevant advantages. In fact, the use of a fixing element between the struts and the cross members is envisaged which allows the production of a stable connection, since it can be locked by tightening a suitable screw.
    [0021] The fixing element is furthermore preferably part of the connecting means which further provides for seats and bent extensions that can be received therein and which allow the struts and cross members to be locked in a direction of movement away from withdrawal. from each other.
    [0023] Therefore, this combination allows the connection between the struts and the cross members to be particularly stable, since the bent extensions cannot be disengaged from the corresponding seats unless the screw of the fixing element has been previously loosened.
    [0025] Furthermore, the struts and cross members used in the present invention can be formed in a simple manner, with no complex mechanical processing operations being necessary for their manufacture.
    [0027] According to a preferred embodiment, the struts and cross members are formed by tubular elements, for example with a square cross section.
    [0029] Preferably, the bent extensions are formed on the cross members and the seats are formed on the strut.
    [0031] According to another aspect, the fixing element is L-shaped to allow its insertion into a suitable depression that is formed in the strut.
    [0033] These characteristics allow the initial positioning of the fixing element and then the interlocking between the bent extensions and the seats to be carried out.
    [0035] Furthermore, as a result of the arrangement of the depression for the fixing element in the strut, by placing it projecting thereon, it is possible to make its installation is particularly simple, and it is not necessary to operate in areas that are only accessible with difficulty.
    [0037] Preferably, in order to position the fixing element precisely and also to keep it stable during the assembly step, it comprises support flanks that are capable of bearing on the upright or the crossbar.
    [0039] In one embodiment, the fixing element comprises a first portion that is capable of being inserted into the corresponding depression and a second portion that is preferably perpendicular to the first portion and that forms the bearing surface that is intended to support the strut or the cross member. , allowing the aforementioned connection.
    [0041] According to another aspect, the fixing element is L-shaped.
    [0043] Preferably, the first portion and the second portion perpendicular to it are defined by the L-shaped development.
    [0045] According to another aspect, the depression is in the form of a slot, the first portion having a length greater than the height of the slot.
    [0047] In this way, when the second portion of the L is inserted into the groove, the removal of the fixing element from the depression is prevented, or at any rate extremely difficult.
    [0049] According to another aspect, the threaded seat in which the fixing screw is fitted is formed on a floating member that is configured to be able to carry out limited translational movements with respect to the support surface of the fixing element. In this way, it is possible to compensate for positioning errors or dimensional errors in the strut and cross member structure.
    [0051] Other advantages, features and procedures for the use of the present invention will be better appreciated from the following detailed description of some embodiments which are presented by way of non-limiting example. Reference will be made to the figures of the attached drawings in which:
    [0052] - Figure 1 is a perspective view, partially in section, of a detail of the frame structure of the pieces of furniture according to the present invention;
    [0054] - Figure 2 is a lateral cross section of the structure of Figure 1;
    [0056] - Figure 3 is a perspective view of the frame structure of the furniture pieces according to the present invention;
    [0058] Figures 4A to 4D are a front view, a perspective view, a side view and a rear view of a fixing element, respectively, a detail of the structure of figure 1;
    [0060] - Figure 5 is a perspective view of a cross member of the frame structure according to the present invention; and
    [0062] - Figure 6 is a perspective view of a strut of the frame structure according to the present invention.
    [0064] Initially referring to Figures 1 to 3, a frame structure 100 for a piece of furniture is generally designated 100. The structure 100 comprises the struts 1 that form the legs 101 of the piece of furniture and the cross members 2 that connect the legs. struts 1 according to a grid-like structure. According to the preferred form, both the struts and the cross members are formed of tubular elements, for example made of steel or other suitable metal.
    [0066] As can be seen from Figure 3, upper and lower cross members connecting the struts can be provided in the region of two different vertical positions. In any case, it will be appreciated that the structure according to the present invention allows the production of a modular structure, providing a plurality of different combinations according to specific requirements.
    [0068] Now, with special reference to Figures 1 and 2, the structure 100 further comprises connecting means 300 which are configured to join the struts 1 to the cross members 2.
    [0069] In one embodiment, the connection means 300 comprise at least two bent extensions 21, 22 that are formed in the cross member 2 and which are better illustrated in Figure 5, and the corresponding seats 11, 12 that are formed in the cross member 1, on the other hand, as can be seen in figure 6. In any case, it is evident that the opposite solution could also occur, with seats formed in the crossbar and extensions formed in the strut.
    [0071] Preferably, the bent extensions 21 and 22 are formed by means of a downwardly bending tongue extending from the surface of the crossbar 2. In the embodiment where the crossbar 2 is formed by a hollow tubular element, the extensions Bent 21, 22 are formed in the region of an open end of the cross member 2.
    [0073] In one embodiment, an upper folded extension 21 and one, preferably two lower extension (s) 22 are provided.
    [0075] It is clear that, in the context of the present invention, the term "upper / lower", similarly to the term "high / low", refers to the vertical direction defined by the piece of real estate to which the structure is applied. of the present invention during normal use.
    [0077] In the cross member 1 a corresponding upper seat 11 and a lower seat or seats 12 are further defined, in which the corresponding extensions fit.
    [0079] Preferably, the upper seat 11 is formed by a chamfer which is formed at an upper end of the strut 2.
    [0081] In this way, the compromise between the extensions and the seats can be obtained in a particularly simple way, it being simply necessary to support the extension in the region of the chamfer.
    [0083] Always for the benefit of ease of assembly, the lower seat 12 forms an opening with a surface greater than the corresponding bent extension 22.
    [0085] As can be understood from Figure 2, the bent extensions 21, 22 are configured so that they fit into the corresponding seats 11, 12 that are formed in the strut 1 and to prevent movement away between the strut and the cross member in the axial direction of the cross member 2.
    [0087] To also obtain a stable connection between the strut and the cross member in a vertical direction, the fixing means 300 of the frame structure according to the present invention further comprise a fixing element 3, which is illustrated in detail in Figures 4A -4D and which can be fitted into a respective depression 13, which is preferably formed in the strut 1.
    [0089] In one embodiment, the fixing element 3 is L-shaped, with a portion 33 of the L that can be inserted into the depression 13 and the other portion 35 projecting from the strut 1 in a projecting manner. According to one aspect of the invention, in order to prevent the fixing element 3 from being inadvertently pulled out of the depression 13, it is constructed in the form of a groove. The height of this groove, that is, the opening of the groove in the vertical direction, is less than the first portion 33 of the fixing element 3.
    [0091] In order to fix the fixing element 3 in its position once it has been inserted into the depression 13, support flanks 34 can be further provided which are able to bear on the strut 1, as can be seen in figure 2. In particular , the wall of the strut 1 is closed similarly to a gasket between the first portion 33 and the bearing flanks 34. Preferably, the bearing flanks 34 extend at 90 ° with respect to the second portion 35 of the fixing element 3 .
    [0093] In the second part 35 of the fixing element there is defined a surface 30 capable of abutting with a bearing surface 10 which is defined in the depression 13.
    [0095] The fixing element 3 further comprises a threaded seat 31, into which the corresponding screw 4 having a head 40 can be inserted. In one embodiment, the threaded seat 31 is formed on a floating member 310 that is configured to be able to carry carry out limited translation movements with respect to the support surface 30, in particular in a plane parallel to the support surface 30 itself.
    [0097] The floating member 310 can be received in a receiving member 37 that can be fixed by means of a joint 36 in the second portion 35 of the fixing element 3.
    [0098] During the assembly of the frame structure of the present invention, the fixing element 3 is initially fixed on the strut 1 by inserting it into the respective recess 13.
    [0100] Subsequently, the cross members 2 are fixed to the upright 1 by hooking the bent extensions 21, 22 with the respective seats 11, 12.
    [0102] Therefore, the locking of the structure is carried out by screwing the screw 4, which is received in a screw seat 24 that is formed in the cross member 2, in the respective threaded seat 31. Preferably, the head 40 and the respective seat 24 they have a conical shape.
    [0104] The head 40 of the screw 4 and the bearing surface are capable of movement towards / from each other when the screw 4 is screwed into the seat 31. Consequently, when the screw 4 is screwed in, the head 4 pushes the cross member 2 towards down acting on the seat of the screw 24 and the bearing surface 30 pushes the strut 1 in the opposite direction, acting on the bearing surface 10.
    [0106] More generally, different configurations could also be used for fastener 3, since bearing surface 30 and head 40 of screw 4 are located on strut 1 and crossbar 2, respectively, or vice versa, following the movement mutual approach / withdrawal generated by the screw 4 being screwed in. In this way, the strut and cross member will be secured in the vertical direction. This assurance, combined with the interlocking described above, allows the frame structure of the present invention to become stable.
    [0108] It is evident that the configuration described above could be used for each connection between the strut 1 / cross member 2 of the structure. For example, if necessary, the connecting means 300 could be present in the region of at least two vertically staggered portions of the strut 1, as illustrated in Figure 3.
    [0110] Therefore, it is clear that the frame structure solves the problems identified with reference to the present invention, providing the use of simple components and requiring only the use of a threaded connection.
