Description

Hidden device for the wall assembly of a structural component of a piece of furniture, with lateral adjustment

The present invention is related to a hidden device for the wall assembly of a structural component of a piece of furniture, with laleral regulation.

These devices are commonly known in the field as hidden hanging brackets.

As a non-limiting example, the invention is described herein by referring to the wall assembly of a wall cupboard, but it can also be used for the assembly of uprights (supports) that are part of a bookcase, or other furniture.

These devices also have the function of allowing height and depth regulations of the furniture assembled on the wall, with respect to the wall itself and adjacent furniture.

The assembly of the furniture on the wall is carried out by means of an arm that extends from the body of the device and is attached to a support, for example a bar, stud, plate or similar element, fixed on the wall.

The height and depth regulations mentioned above are carried out by acting on said arm through various types of mechanisms, which are controlled (from outside the device) by means of a maneuvering tool (for example a screwdriver).

The present invention is specifically related to what is called a central support bracket, that is to say a hidden type hanging bracket, intended to be inserted into a seat located within a support of a piece of furniture, for example a wall cupboard or other furniture component.

According to EP 1,535,539 A1, a concealed device for wall assembly with a structural component of a piece of furniture, comprising: a movable arm for hooking said device to a fixed support on the wall, the position of said arm with respect to said wall it is regulated with respect to height and depth by means of two different regulation mechanisms respectively, said regulation mechanisms are contained completely within a body, in the form of a box, from a front side from which a end, in the form of a hook, of which arm, said body, in the form of a box, is composed of two half-shells that, in correspondence with said front side, comprise means for fixing the device within a seat of said piece of furniture component , the device is inserted into said seat, on one side of said body, in the form of a box, there are also means of access relative to said mechanisms, according to the X axes that are in substantially perpendicular planes with respect to said box-shaped side of said body, said fixing means comprise an upright in which said box-shaped body is fixed by means of fixing means .

So-called central support brackets must meet the following main requirements.

First of all, its general configuration should be such as to allow easy and safe assembly within the furniture support, even if the relative seat is not perfectly complementary (which fits perfectly).

Secondly, its structure must be such as to ensure a firm and secure fixation to the furniture support: that is, the tensioned wall cupboard must not detach from its seat, causing the cupboard to fall.

Third, the above-mentioned height and depth control mechanisms of the furniture must be easily accessible and maneuverable from the outside: that is, even if the hanging support is inserted into the support of a cupboard, this must be independent of the type and position of the articulation system (hinged) of the door of the same cupboard.

An additional requirement that must be met by the central support brackets is that they must comprise mechanisms for regulating the height and depth cupboard that are simple to produce and assemble and have reliable operation.

The general objective of the present invention is therefore to provide a central support support that is capable of satisfying the requirements mentioned above, overcoming the drawbacks of the known technique.

This objective is achieved by means of a device, called a central support pendant support, having the characteristics specified in claim 1 and in the attached subclaims.

The structural and functional characteristics of the invention and its advantages over the known technique will seem more understandable from the following description, referring to the accompanying drawings, which show a possible practical embodiment of the invention itself.

Figure 15 is a perspective view illustrating a wall cupboard equipped with the support pendant support central according to the invention illustrated in Figures 1-14; Y

Figures 16-21 are views corresponding to Figures 1-6, illustrating a possible further embodiment of the invention.

Figures 1-13 of the drawings illustrate a possible embodiment of the invention in which the assembly device is indicated as a set with the reference number 20, and is of the so-called hidden type, in particular intended to be incorporated into a component of a piece of furniture, for example a stud or panel 21.

As already specified, devices of this type are commonly known as central support hanging brackets. The device 20 structurally consists of a flat rectangular body 22, which characteristically comprises two half-shells 23,24, coupled together, and partially containing a hitch arm.

25.

The arm 25 can rotate around a pin 26 in the directions of the arrow F, and can also be moved back and forth in the directions of the arrow F1 (figure 5).

The rotation and translation of the arm 25 are controlled by means of two independent control mechanisms, which are indicated as a set with the numerical references 27, 28, respectively.

The mechanism 27 serves to regulate the height (vertically) of the position of the panel 21, while the mechanism 28 serves to regulate the depth of the position (horizontally).

More specifically, as can be clearly seen in the various illustrative figures, the hitch arm 25 is a single piece shaped like a fork, with spaced apart branches 29, opened from behind and flattened and shaped in the front, which they define a width 30 protruding through an opening 31 of the body 22. The hook 30 is intended to engage within an opening 75 of a support 76 fixed to a wall 77. Said branches 29 of the arm 25, near the open rear end, they are perforated as in 32, to receive pin 26 in which they can rotate.

As can be clearly seen in the drawings, the hitch arm 25 is guided in its rotational and translational movements by the internal surfaces of the body 22 (figure 6)

The mechanism 27, which controls the rotation of the arm 25 around the pin 26, comprises a screw 33 that is screwed into a hexagonal sliding nut 34.

For this purpose, the screw head is rotatably housed in a corresponding seat 40 'of the two half-shells 23,24, as well as the hexagonal nut 34 which is moved in the guides 39.

The thyme 33 rotates inside a hexagonal nut 34 which, when moving, acts on the terminal edge 36 of a curved section 37 that slides into a corresponding slit 38 of the body 22.

The end of said section 37 opposite 36 is damped against the branches 29 of the hitch arm 25.

The head of the screw 33 comprises a toothed crown 40 with which a gear 41 is engaged, which rotates in a pin 42 whose axis of rotation is perpendicular to that of the screw 33. The pin 42 is housed within a hole 42 'of the half-housing 23.

A seat 43 is located in the gear 41 so that a maneuvering tool passes through a hole 44 of the half-shell 24.

The components 33, 34, 40, 41,42 of the control mechanism mentioned above, as can be clearly seen in the drawings, are housed within a corresponding seat defined by the coupling between the two half-shells 23,24 and partially indicated with 45 in Figure 3

The mechanism 28, which controls the translation of the arm 25, comprises a thyme 46 that is screwed through a threaded hole 47 of the pin 26 in which the arm 25 rotates.

As can be clearly seen in the drawings, in particular in figures 5 and 6, the translation of said thyme 46 is blocked in the front by a support 48 and in the rear by a seat 49, in which the assembly is rotatably assembled. own thyme 46.

More specifically, the pointed front end 50 of the screw 46 is rotatably housed in a seat 51 of the holder 48, while the head at the opposite end comprises a toothed crown 52 through which a gear 53 is coupled, which can rotate in a pin 54 whose axis of rotation is perpendicular to that of screw 46. The pin 54 is housed in a hole 54 'of the half-shell 23.

A seat 55 is positioned in the gear 53 for a maneuvering tool to pass through a hole 35 of the half-shell 24.

The thyme 46 is rotatably held, in correspondence with the toothed crown 52, within a slit 56 of the holder 49, which in turn is firmly inserted into a seat 57 defined by the coupling between the two half-shells 23,24.

The components of the aforementioned conlrol mechanism28, as can be clearly seen in the drawings, are housed within a corresponding seat defined by the coupling between the two half-shells 23, 24, said seat is partially indicated with 58 in Figure 3.

The half shells 23, 24 are firmly coupled together, containing the kinematic mechanisms described above, by means of a plurality of pins 59.

The body 22 described above, containing the mechanisms 27, 28 for regulating respectively the height and depth of the panel 21 (and consequently the cupboard of which said panel 21 can be part), typically also comprises a box-shaped upright , 60 to fix the central support pendant support 20 to the panel 21, as explained below.

Said post 60 is structurally composed of a core 61 reinforced by a perimeter edge 62, connected at the ends, as clearly illustrated in the drawings.

The core 61 of the post 60 has an opening 63 in which the flat rectangular body 22 of the hanging support is assembled and fixed (Figure 7-10).

For this purpose, a box-shaped refining tooth, 64, protrudes in correspondence with the edge of the body 22 above the hook 30, which defines, with the same body 22, a slit 65.

A fixing pin 66 extends, in correspondence with the edge of the body 22, below the hook 30.

In this way, the body 22 can be fixed to the post 60, in correspondence with the opening 63, as illustrated in the sequence of Figures 7-10, that is to say by passing the tooth 64 first through the opening 63, and then inserting the slit 65 in the core 61 and the pin 66 inside a hole 67 of the core 61. Finally, the pin 66 is riveted, as in 68, over the core 61 itself, to obtain a solid, stable and secure connection between body 22 and stud 60 (figures 5,10,13).

As can be clearly seen in the drawings, the opening 63 is eccentric, that is, it is placed closer to the upper end of the stud 60, with respect to the lower end.

In this way, two lever arms 81 and 82, longer and shorter respectively, whose important function will be described below, are defined in the fixing post 60.

The arm 81 is placed under the body 22, while the arm 82 is above the body.

The structured central support pendant support 20, as described above, is firmly fixed to the panel 21 in the following manner, with particular reference to Figures 11-14.

The seats 69, 70 are located in the panel 21, in which the body 22 and the fixing post 60 of the hanging support 20 are housed - also with a free space (enlarged figure 14).

The hanging bracket 20 is firmly fixed on the site by means of the box-shaped stud, 60 that is screwed onto the panel 21 by means of a plurality of screws 71 that pass through holes 72 of the core 61 of the stud 60 itself .

Figure 15 illustrates, as a non-limiting example, the hidden central support hanging support according to the invention incorporated into the support 21 of a wall cupboard M.

The wall cupboard M is equipped with a hinged door A by means of an articulation system S of known type, which allows its rotation (around a horizontal axis) upwards (to open) and vice versa (to close).

As can be clearly seen from the enlarged detail of Figure 15, despite the disturbing presence of the articulation system S of the door A - which in fact makes a hanging bracket of the visible type inaccessible from the front (see for example the European patent EP 0033179) -, the hidden central support pendant support according to the invention, is easily accessible, from the side, by means of maneuvering screwdrivers C which are introduced through the holes 73, 74 in the panel 21 coaxial with the holes 44, 35 in the half-housing 24 of the body 22 (Figure 15), according to the X axes that are in substantially perpendicular planes to the sides 78 of the body, box-shaped, 22.

In this way it is possible to access the height and depth adjustment mechanisms 27, 28 of the furniture M, as explained above.

The height and depth adjustment of the cupboard M with respect to the wall 77 (and also possibly with respect to other adjacent furniture not shown) is performed by acting on the gears 41 and 53, respectively.

The rotation in one direction or another of the gear 41 (and the crown 40), in fact, causes a rotation of the arm 25 around the pin 26, due to the rotation of the screw 33 and the translation of the curved section 37, pushed by the sliding nut 34.

The arm 25 is, in fact, always in contact with the section 37 thanks to the weight of the cupboard of which the panel 21 is part.

The rotation in one direction or another of the gear 53 (and the crown 52), on the other hand, causes a translation of the arm 25, due to the tightening of the screw 46 in the hole 47 of the pin 26, which is consequently induced to move forward and back integrally with arm 25.

The seats 43 and 55 of the gears 41 and 52 are accessible for a maneuvering tool (for example a screwdriver) introduced through the respective coaxial holes 73 and 74 located in the panel 21 (Figure 15).

The enlarged figure 14 shows how, thanks to the hidden central support hanging support according to the invention, the serious problem of decoupling the body 22 of the hanging support of the respective seat 69 is resolved, even if the latter does not have a perfect size.

The problem is solved with the fixing post 60 with the lever arms B1 and 82, longer and shorter respectively, which prevent a right rotation of the panel 21 (under tension F1) around the hinge point P, thanks to the action of the forces of the components R1, R2 YR3, Y of the resulting moment M1.

The collaboration between the core 61 and the perimeter edge 62 of the box-shaped fixing post 60 is significant for this purpose.

Figures 16-21 illustrate a possible further embodiment of the invention, wherein the components, equal or substantially equivalent, to those illustrated in Figures 1-15 are indicated with the same reference numbers increased by 100.

The difference between the first and the second embodiment of the invention (illustrated in Figures 16-21) is that in the second embodiment a fixing post 160 of the device 120 is conceived to the panel 21, which is characteristically produced integrally with the Half-enclosure 123 of the flat body 122. This embodiment is clearly illustrated with particular reference to Figures 18,19 Y20 of the drawings.

The production of the stud 160 integrally with the half-housing 123 defines a recess 200 in the latter, in which a flange 201 of the half-housing 124 is housed, which is thus firmly fixed to 123 by means of pins

159.

Therefore, the objectives indicated in the preamble of the description have been achieved.

The scope of the invention is defined in the following claims.
