DESCRIPTION

Visible device for mounting a wall cabinet, with lateral adjustment

The present invention relates to a visible device for wall mounting of a wall cabinet, said device being commonly referred to in the field as visible hangers.

A visible hanging bracket of this type is described and illustrated, for example, in European Patent EP 0033179.

These devices also have the function of allowing height and depth regulation of the mounted wall cabinet, with respect to the wall itself and the adjacent furniture pieces.

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

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

As is well known to those skilled in the art, and as is evident from the description that follows, these hanging brackets are fixed to the edge of a wall cabinet, in correspondence with the top and the lining, when the last It is planned. This means in correspondence with the upper edges of the wall cabinet opposite the opening - closing doors.

When the closet doors are articulated to make a movement around a vertical axis, or they are sliding, axial access to the previous adjustment mechanisms with a screwdriver is allowed without any particular problem.

This is not the case when the cabinet door is articulated to move around a horizontal axis, that is, to rotate upwards (opening) and in the opposite direction (closing).

The articulation systems of the door around a horizontal axis are, in general, quite difficult, preventing access in an axial direction, by means of a screwdriver, to the height and depth adjustment mechanisms that have been indicated. higher.

Visible hangers must also meet the following main requirements.

In the first place, its general configuration must be such that it allows easy and safe fixing to the flanges of the cabinet, regardless of the possibility of a so-called back covering.

Secondly, its structure must be such that it ensures a firm and secure fixation to the flange of the cabinet, even without a back cover.

Thirdly, the previous height and depth adjustment mechanisms must be easily accessible and maneuverable from the outside, regardless of the type and position of the articulation system (hinged) of the door to the same cabinet.

An additional requirement that must be satisfied by the visible hangers is that they must include height and depth control mechanisms for the cabinet, that are easy to produce and assemble and that have reliable operation.

According to the prior art patent document DE 2907970 a device for wall mounting of a structural element of a piece of furniture of the type comprising a mobile arm for hooking the device to a support fixed to the wall is disclosed , and in which the position of the arm with respect to the wall is regulated in terms of height and depth by means of two different adjustment mechanisms contained entirely within a box-shaped body. The box-shaped body is composed of two semi-helmets firmly coupled to each other by means of fixing arranged on the side of the body in the form of a box, and additional fixing means are also provided for fixing the body to the furniture.

WO2010 / 012504 A1 discloses another fastening device.

Therefore, the general objective of the present invention is to overcome the drawbacks of the known technique by providing a visible hanging support that can be used indifferently with wall cabinets equipped with doors that has both an opening with a movement around an axis. vertical, and an opening with a movement around a horizontal axis.

- Figure 22 is a perspective view, with an enlarged detail, illustrating a wall cabinet equipped with a visible hanging bracket produced in accordance with the invention, in which the wall cabinet door is articulated to move around a horizontal axis, that is, up (opening) and in the opposite direction (closing).

Figures 1 to 10 of the drawings illustrate a first possible embodiment of the invention in which the device of

assembly is indicated as a whole with reference numeral 30, and is of the type called visible.

As already specified, devices of this type are commonly referred to as visible supports for hanging in the field.

The device 30 is structurally composed of a flat rectangular body 31, which characteristically comprises two half-helmets 32, 33, coupled to each other, and partially containing a hitch arm 34.

The arm 34 can be rotated around a pin 35 in the directions of the arrow F, and it can also be moved back and forth in the directions of the arrow F1 (Figure 9).

The rotation and translation of the arm 34 are controlled by means of two separate control mechanisms, which are indicated as a whole with the numerical references 36, 37, respectively.

The mechanism 36 serves to regulate the height (vertically) of the position of the cabinet M, while the mechanism 37 serves to regulate the depth of the position (horizontally).

More specifically, as can be seen clearly in the various illustrative figures, the hitch arm 34 is a single fork-shaped piece, with branches separated from each other 38, opened behind and shaped

in the front part, which defines a hook 39 that protrudes through an opening 40 of the body 31. The hook 39 is intended to be hooked to a B-shaped support bar fixed to a wall P (figure 5).

The mentioned branches 38 of the arm 34, near the open rear end, are perforated as in 41, in order to receive the pin 35 on which they can rotate.

As can be clearly seen in the drawings, the hooking arm 34 is guided in its rotational and translational movements by the internal surfaces of the body 31 (Figure 10).

The mechanism 36, which controls the rotation of the arm 34 around the pin 35 comprises a screw 42 which is screwed into a hexagonal sliding nut 43.

For this purpose, the head of the screw 42 is housed in a complementary seat 49 'of the two semi-helmets 32, 33, while the hexagonal nut 43 is moved over grains 48.

The screw 36 rotates inside the hexagonal nut 43 which, when moved, acts on the end edge 45 of a curved section 46 that slides into a corresponding groove 47 of the body 31.

The end of said section 46 opposite 45 is damped against the branches 38 of the hitch arm 34.

The head of the screw 42 opposite 44, comprises a toothed crown 49 to which a gear 50 is applied, which rotates on a pin 51 whose axis of rotation is perpendicular to that of the screw 42.

The pin 51 is housed inside a hole 51 'of the semi-hull 32.

A seat 52 is located in the gear 50 for a maneuvering tool that passes through a hole 44 of the semi-helmet 33.

The components 42, 43, 49, 50, 51 of the previous control mechanism, as can be clearly seen in the drawings, are housed within a corresponding seat defined by the coupling between the two half-helmets 32, 33 and which is indicated partially as 53 in figure 1.

The mechanism 37 that controls the translation of the arm 34, comprises a screw 54 that is screwed through a threaded hole 55 of the pin 35 on which the arm 34 rotates.

As can be clearly seen in the drawings, in particular in figures 9 and 10, the translation of said screw 54 is locked at the front end by a support 56 and at the rear end by a seat 57, on which the same screw 54 is rotatably mounted.

More specifically, the pointed front end 58 of the screw 54 is rotatably housed in a seat 59 of the support 56, while the head at the opposite end comprises a toothed crown 60 whereby a gear 61 is applied, which can rotate on a pin 62 whose axis of rotation is perpendicular to that of screw 54.

The pin 62 is housed in a hole 62 'of the semi-hull 32.

A seat 63 is located in the gear 61 for a maneuvering tool that passes through a hole 64 of the semi-helmet 33.

The components of the previous control mechanism 37, as can be clearly seen in the drawings, are housed within a corresponding seat defined by the coupling between the two half-helmets 32, 33, said seat being partially indicated by 65 in the figure one.

The half-helmets 32, 33 are firmly coupled to each other, containing the kinematic mechanisms described above, by means of a plurality of pins 66.

The front part of the semi-helmet 33 (from which the hook 39 extends) preferably has a flange 67 that is damped against a lining 68 (if present) of the cabinet M (Figure 18).

As can be clearly seen in Figure 8 of the drawings, the hanger bracket 30 according to this embodiment of the invention is fixed to the flange 69 of the cabinet M by means of a plurality of screws 70 that pass through respective holes 71 in the hull means 32, 33 of the body 30 (Figure 8).

Figures 11 to 20 illustrate a second possible embodiment of the invention, in which elements equal and / or equivalent to those illustrated in Figures 1 to 10, are indicated with the same reference numbers, incremented by 100 , and will not be described further.

This second embodiment of the invention, in fact, only differs from the first embodiment in the fixing means of the support for hanging 130 to the flange 169, which instead of consisting of through screws 70, are composed of pins 172.

As can be clearly seen in the drawings, said pins 172 protrude from the semi-helmet 132 of the body 131, in correspondence with the lower side of the latter.

Each pin 172 is axially perforated, as in 173, to receive a fixing screw 174 of the same pin 172 to the body 131 of the hanging bracket, whose semi-helmets 132, 133 are perforated for the purpose, as in 175 (Figure 19). ).

As can be clearly seen in Figure 19 of the drawings, the screws 174, together with other screws 174 ', consequently also produce the redproc fixation of the half-shells 132, 133, forming the body 131 of the hanging bracket .

More specifically, the pin 172 comprises a sawtooth section 176 equipped with a rod 177 housed inside an integral bushing 178 with the half-shell 132 of the body 131.

In this way, the hanger bracket 130 can be firmly fixed on the flange 169 of the cabinet M by the pressurized insertion (with interference) of the pins 172 into the holes 179 of the same flange 169 (Figures 18, 22) .

The height and depth adjustment of the cabinet M with respect to the wall (and possibly also with respect to other pieces of adjacent furniture not shown) is carried out by acting on the gears 50, 150 and 61, 161, respectively.

Rotation in one direction or another of the gear 50, 150 (and the crown 49, 149), in fact causes a rotation of the arm 34, 134 around the pin 35, 135, due to the rotation of the screw 42, 142 and the translation of the curved section 46, 146, pushed by the sliding of the nut 43, 143.

The arm 34, 134, in fact, always remains in contact with section 46, 146 thanks to the weight of the cabinet of which panel 69, 169 is a part.

Rotation in one direction or another of the gear 61, 161 (and the crown 60, 160), on the other hand, causes a translation of the arm 34, 134, due to the tightening of the screw 54, 154 in the hole 55, 155 of the pin 35, 135, which consequently is induced to move forward and backward integrally with the arm 34, 134.

Seats 52, 152 and 63, 163 of gears 50, 150 and 61, 161 are accessible for a maneuvering tool (for example a screwdriver) which is introduced through respective coaxial holes 44, 64 and 144, 164 located in the semi-helmet 33, 133, on the side 80, 180 of the box-shaped body 31, 131.

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

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