Description

Technical Field

[0001] This invention relates to an adjustable base for mounting furniture doors with a double-hinged quadrilateral hinge. Background Technology

[0002] Specifically, but not limited to, in the furniture industry, hinges with double quadrilateral shapes are known. These hinges essentially consist of a system of hinge rods with associated springs, allowing a door leaf that can swing relative to the fixed structure of the furniture to move between a closed and an open configuration. Such hinges typically have mounting connection elements that utilize threaded elements or similar perforations within the door leaf and the furniture structure.

[0003] Holes are provided on the door leaf and the structure of the furniture, and the distribution of these holes is a mirror image of the distribution of holes in the connecting elements of the hinges that will be installed by inserting threaded connecting elements.

[0004] Typically, these hinges are used to move horizontally extending door panels, and these hinges are located between the lower surface of the upper horizontal wall of the furniture structure and the upper portion of the inner surface of the door panel.

[0005] During furniture assembly, the doors must be correctly positioned relative to the furniture's structure, especially ensuring they are horizontally centered. This requirement is even more pronounced when two or more closets are placed horizontally side-by-side, and their doors must not interfere with each other. Furthermore, if at least three closets are hung side-by-side, the respective doors must be positioned to pair them and space them evenly.

[0006] To ensure that the door is horizontally centered relative to the furniture compartment, the hinge must currently be removed by loosening the corresponding threaded element and then reattached. If necessary, new holes need to be formed in the structure of the furniture and / or in the door.

[0007] This operating model is not without its drawbacks. In order to center the door relative to the furniture, the furniture assembly time needs to be significantly extended and labor costs are increased accordingly, because workers must keep trying until they determine that the hinges are in the optimal position.

[0008] Furthermore, the speed and accuracy of these interventions are significantly influenced by the workers' experience and practical skills. Summary of the Invention

[0009] The object of the present invention is to eliminate the aforementioned disadvantages of the prior art by providing an adjustable base with a double-hinged quadrilateral hinge for mounting furniture doors, which allows the position of the door to be adjusted relative to the structural level of the furniture without disassembling, repositioning and reattaching components, and thus reducing labor time and costs.

[0010] Within this objective, the object of the present invention is to provide an adjustable base for mounting furniture doors with a double-hinged quadrilateral hinge, which allows for easy and reliable adjustment without relying on the worker's level of experience.

[0011] Another object of the present invention is to provide an adjustable base for mounting a furniture door leaf with a double-hinged quadrilateral hinge, the adjustable base having a simple and compact structure, so as to substantially not change the overall volume and profile of the hinge in which the adjustable base is incorporated, and not to complicate its installation.

[0012] Another object of the present invention is to provide an adjustable base for mounting a double-hinged quadrilateral hinge for furniture doors, the adjustable base being adaptable to different types of double-hinged quadrilateral hinges.

[0013] Another object of the present invention is to provide an adjustable base with a double-hinged quadrilateral hinge for mounting furniture doors, the adjustable base having a simple structure that is easy to implement and practical, safe to use and effective in operation, and low cost.

Detailed Implementation

[0017] Referring to the accompanying drawings, reference numeral 1 generally indicates an adjustable base with a double-hinged quadrilateral hinge for mounting furniture doors.

[0018] The base 1 includes a fixing element 2 having a first surface 3 and a second surface 4. The first surface is adapted to associate with the interior surface of the wall P of the furniture, and the second surface is arranged opposite to the first surface 3. More specifically, the first surface 3 has at least one substantially flat portion 3a adapted to be positioned for attachment to the wall P.

[0019] Typically, the base 1 is designed to be installed on the lower surface of the upper wall P, which defines the internal compartment of the furniture that is closed by the door A.

[0020] The base 1 also includes at least two opposing wings 5 ​​that protrude from the second surface 4 and are provided with at least a pair of first holes 6 that are aligned with each other to support a connecting pivot 7 that can be associated with the hinge rod of the double quadrilateral hinge 100.

[0021] Wing 5 extends substantially parallel to the longitudinal direction L, and connecting pivot 7 is arranged substantially parallel to the transverse direction T between the wings.

[0022] In this specification, the term "substantially" means "in addition to the usual machining tolerances and assembly tolerances of components".

[0023] The base 1 also includes a generally plate-shaped connecting element 8, which is located between the wings 5 ​​and associated with the fixing element 2, so that the connecting element can slide along the lateral direction T.

[0024] The connecting element 8 and the wing 5 can be made into a single, essentially U-shaped part, for example, by deforming a plate with a suitable profile.

[0025] The terms “plate-like” or “sheet-like” refer to a three-dimensional element whose extent along two dimensions is much greater than its extent along a third dimension.

[0026] The first surface 3 of the fixing element 2 is associated with the movable seat 9 for moving the connecting element 8.

[0027] Preferably, the contour of the first surface 3 integrally defines the movable seat 9 with the fixing element 2.

[0028] At the movable seat 9, the fixed element 2 is provided with at least one groove 10, through which at least one of the two wings 5 ​​is inserted to protrude from the second surface 4 of the fixed element and to move in the lateral direction T in a reciprocating sliding motion.

[0029] In a preferred embodiment, the fixing element 2 has a substantially constant thickness, and the outline of the fixing element defines a recessed bend at the first surface 3, which defines the movable seat 9.

[0030] Alternatively, the fixing element 2 may have a recess defined at the first surface 3 within the thickness of the fixing element to define the movable seat 9.

[0031] Preferably, the fixing element 2 is further provided with two or more teeth 11 at an edge suitable for being arranged along the edge of the wall P of the furniture, for abutting against the thickness of the wall.

[0032] Typically, the fixing element 2 is connected to the wall P by inserting a threaded connection element (such as a screw V).

[0033] At the flat portion 3a of the fixing element 2, there are multiple through holes 23 for inserting such threaded connection elements.

[0034] The hinge 100 is of the type including a first hinge quadrilateral 101 and a second hinge quadrilateral 103. The first hinge quadrilateral 101 is provided with a first connecting element 102 that can be associated with the inner surface of the wall P of the furniture, and the second hinge quadrilateral 103 is provided with a second connecting element 104 that can be associated with the door A of the furniture.

[0035] Typically, hinge 100 is installed between the upper wall P of the compartment defining the furniture and the corresponding closing door A hinged at its upper edge. Wall P is typically horizontally arranged, and a first connecting element 102 is applied to the lower surface of the wall.

[0036] Each hinged quadrilateral 101 or 103 consists of multiple hinge rods, which are not described in detail.

[0037] Hinges 100 are adapted to alternately present an open configuration and a closed configuration, wherein door leaf A opens or closes an access opening to a compartment defined inside the furniture.

[0038] The first connecting element 102 includes the base 1 according to the present invention as described below.

[0039] In addition, hinge 100 is typically provided with a resilient device associated with hinged quadrilaterals 101 and 103, which cooperates in movement between an open configuration and a closed configuration, and the hinge may include a damping device that functions when the hinge is closed and / or open. These devices are not shown and described in detail because they are conventional.

[0040] In a preferred embodiment, the fixing element 2 includes two slots 10, and a corresponding wing 5 is inserted through each of the two slots to protrude from the second surface 4 of the element and to move in the lateral direction T in a reciprocating sliding motion.

[0041] Each slot 10 extends in the longitudinal direction L and is substantially equivalent to the extension of the corresponding wing 5. Each slot 10 extends in the transverse direction T more than the extension of the corresponding wing 5 to allow the wings to slide alternately in that direction.

[0042] Furthermore, at least one reference pin 12 protrudes from the connecting element 8 toward the fixing element 2 and is inserted such that it can move in the guide slot 13, which is defined in the same fixing element at the moving seat 9 and extends in the lateral direction T.

[0043] The pin 12 has a first end integral with the connecting element 8, which engages in a corresponding hole 8a, and a second end associated with an enlarged head 12a arranged beyond the second wall 4 of the fixing element 2. The head 12a prevents the connecting element 8 from separating from the fixing element 2.

[0044] Preferably, there are two pins 12, which are distributed longitudinally along the connecting element 8 and inserted into corresponding guide slots 13 defined in the fixing element 2.

[0045] The extension range of the groove 10 and the guide slot 13 along the lateral direction T defines the width of the adjustment stroke of the connecting element 8 of the support wing 5 along this direction, and it can be in two lateral positions relative to the fixing element 2. Figure 3 and Figure 8 The image shows one of the side positions. The wing 5 moves between these two side positions, and in these two side positions, the wing 5 passes through the middle position (in...). Figure 2 and Figure 7 (As shown in the figure) it abuts against one edge of the corresponding groove 10, in which the wing 5 is arranged at the midpoint of the corresponding groove 10.

[0046] It should be noted that the longitudinal extension range of the connecting element 8 and the movable seat 9 is greater than that of the wing 5 and the corresponding groove 10. In this way, the longitudinal end of the connecting element 8 can slidably abut against the corresponding continuous strips 3b and 3c of the first surface 3 at the movable seat 9, thereby giving the base 1 greater robustness.

[0047] Furthermore, it should be noted that at least one edge 8b extending transversely to the longitudinal direction L of the connecting element 8 slidably abuts along the corresponding side 9a of the movable seat 9 to define a positioning guide structure for sliding the element along the seat. In possible embodiments ( Figure 4 In this embodiment, the movable seat 9 is open on one side, and the connecting element 8 has a single edge 8b that slides in contact with the corresponding side 9a of the seat. In a variation of the embodiment ( Figure 4a In the case, the movable seat 9 is fully recessed in the fixed element 2, and the connecting element 8 has two opposing edges 8b that slide in contact with the corresponding side of the seat.

[0048] Usefully, the base 1 may have a reinforcing element 15, which is substantially U-shaped and includes: a substantially flat central portion 16 integrally and slidably associated with the connecting element 8 by a pin 12, and the central portion being slidably associated with the second surface 4 of the fixing element 2; and at least a pair of sidewalls 17 arranged inside the wing 5, and including at least a pair of aligned second holes 18 through which at least one connecting pivot 7 is inserted.

[0049] The pin 12 is inserted using a corresponding through hole defined on the middle portion, wherein the corresponding head 12a abuts against that portion.

[0050] In the illustrated embodiment, the wing 5 has two pairs of first holes 6 aligned with each other, into which corresponding connecting pivots 7 are inserted. Furthermore, there are two pairs of sidewalls 17, each pair of which supports a corresponding pair of second holes 18 aligned with the corresponding pair of first holes 6. Each connecting pivot 7 is inserted through a pair of first holes 6 and a corresponding pair of second holes 18.

[0051] Advantageously, the base 1 includes an actuation device 19 for sliding along the lateral direction T of the connecting element 8, which supports the wing 5 relative to the fixing element 2.

[0052] In a preferred embodiment, the actuating device 19 includes an eccentric pivot 20 that is rotatably engaged in a seat 21 defined in the connecting element 8 and is accommodated such that the eccentric pivot can move within a longitudinal slot 21 provided in the fixing element 2.

[0053] The eccentric pivot 20 includes an actuating mechanism 22 for rotational actuation relative to the seat 21. For example, the actuating mechanism 22 may have a coupling seat that can be coupled to the eccentric pivot 20 for rotational actuation. Figure 6 The tool U is associated with ).

[0054] The eccentric pivot 20 includes: a cylindrical rod 20a, rotatably engaged in a seat 24; and a round head 20b, offset relative to the rod, which is movable within a longitudinal slot 21.

[0055] Conveniently, apart from the thickness of the fixing element 2 in which the longitudinal slit 21 is defined, the round head 20b occupies very little space, so that it does not interfere with the components of the hinge 100 in the open and closed configurations during use.

[0056] The longitudinal seam is substantially the same size as the diameter of the round head 20b in the transverse direction, but has a greater longitudinal extension.

[0057] The circular head 20b abuts against the periphery of the longitudinal seam 21 on the portion that is opposite to each other in the diametrical direction, thus actuating the connecting element 8 of the support wing 5 to slide relative to the fixed element 2.

[0058] In the illustrated embodiment, the operating device 16 is formed by a crosshead notch defined on the circular head 20b of the eccentric pivot 20 for inserting a tool U, such as a conventional screwdriver, but it may have a linear notch or a hexagonal socket for connection with different tools for rotating actuation of the pin.

[0059] By changing the angular configuration of the eccentric pivot 20, the relative position of the connecting element 8 of the support wing 5 with respect to the fixed element 2 in the lateral direction T can be altered. When the base 1 is engaged in the hinge 100, this adjustment can change the position of the hinge relative to the fixed element 2, and thus change the position of the door leaf A relative to the wall P of the furniture, that is, more generally, relative to the structure of the furniture.

[0060] In practice, it has been found that the adjustable base with a double-hinged quadrilateral hinge for mounting furniture doors, as described in the invention, achieves the intended purpose and objective, and specifically, it is noted that the components of the adjustable base according to the invention are easy to provide and assemble, and the base allows for easy and reliable adjustment of the hinge during assembly, thus reducing time and labor costs.

[0061] Furthermore, the adjustable base according to the invention can be easily adapted to a variety of hinges with minimal structural modifications.

[0062] Finally, the adjustable base according to the invention is compact and does not significantly alter the volume and profile of the hinge in which the adjustable base is incorporated, thus not complicating its installation.

[0063] Therefore, the conceived invention can be modified and varied in many ways, all of which are within the scope of the appended claims.

[0064] Furthermore, all details can be replaced by other technically equivalent components.

[0065] In practice, the materials used, as well as the dimensions and shapes as appropriate, can be arbitrary as required without deviating from the scope of protection required herein.

[0066] This application claims priority to Italian Patent Application No. 102023000014214, the disclosure of which is incorporated herein by reference.

[0067] Where any technical feature mentioned in a claim is followed by a reference numeral, the purpose of including such reference numerals is solely to increase the comprehensibility of the claim, and therefore, such reference numerals do not have any limiting effect on the interpretation of each element indicated by way of example by such reference numerals.
