The present invention relates to a hidden hanging- bracket equipped with regulation mechanisms from above and a perfected anti-disengagement device.

As is known to experts in the field, hidden hanging-brackets of the known type for the wall assembly of wall-cupboards are fixed to the shoulder, top and/or lining of the cupboard, in correspondence with the rear angles of the same.

Hanging-brackets of the known type are equipped with a first regulation mechanism in height (vertical) , and possibly also a second regulation mechanism in depth (horizontal) , both assembled on a supporting base.

Said supporting base is fixed to the shoulder, top and/or lining of the cupboard by fixing means, such as, for example, screws.

These regulation mechanisms comprise respective manoeuvring screws which are accessible from above through the top of the cupboard.

Anti-disengagement means or devices, which prevent the accidental disengagement of the hanging-bracket from the wall support (generally a plaque or bar) , when subjected to abnormal stress, for example accidental upward forces, cooperate with these regulation mechanisms .

Hanging-brackets of this type are described for example in documents: PCT/EP2010/001601 , PCT/EP2011/001593, EP2011191356.2 and EP2012181826.4.

Hanging-brackets of the known type, whether they be hidden or visible, are equipped with an anti- disengagement device whose functioning can be associated with that of regulation mechanisms in height and depth: or, the anti-disengagement device can be autonomous with respect to these mechanisms.

When the anti-disengagement device is operatively interconnected with the regulation mechanisms, its functioning is caused by the presence of the regulation mechanism in depth of the hanging-bracket; this is a limitation as, also for economic reasons, it is necessary to have hanging-brackets equipped with the regulation mechanism in height (vertical) alone.

In addition, interior architecture is increasingly proposing wall-cupboards consisting of only one module (only one wall unit), therefore open on all sides, which makes it necessary to have an almost zero distance between the rear part of the cupboard and the wall. In other words, the hanging bracket must be entirely contained in the so-called "sanitary space" present between the lining and the wall.

A general objective of the present invention is to provide a hidden hanging-bracket with an anti- disengagement device, equipped with at least one regulation mechanism in height (vertical), which is operatively interconnected with said anti-disengagement device.

A further objective of the invention is to provide a hanging-bracket of the type described above, wherein the encumbrance of the anti-disengagement device is contained in the thickness of the same hanging-bracket: in other words, the thickness of the hanging-bracket must be contained in the "sanitary space" present in the rear part of the cupboard between the lining and the wall.

Another objective of the invention is to provide a hanging-bracket of the type described above which is economical to produce and assemble, and has a precise and safe functioning.

The objectives listed above are achieved by a hanging-bracket having the characteristics specified in the enclosed claim 1 and subclaims.

With reference to figures 1-6 of the drawings, according to a first illustrative and non-limiting embodiment of the invention, a hanging-bracket 50 is structurally composed of a base 51 on which a first regulation mechanism 52 in height (vertical) and a second regulation mechanism 53 in depth (horizontal), are assembled.

Said two mechanisms 52,53 can be of the known type, and will therefore not be described herein in great detail. As a non-limiting example, said mechanisms 52, 53 can be of the type described and illustrated in the document EP2012181826.4 to which reference should be made, if necessary, for further clarifications, and which should be considered an integral part of the present description.

The base 51 has perimetric flanges 54, 55 with holes 56, 57 for fixing it, by means of screws, to shoulders 58 and to a top 59 respectively of a wall- cupboard 60 (figures 7-16) .

The base 51 also has holes 61 for the passage of fixing screws (possible) of the hanging-bracket to a lining 62 of the wall-cupboard 60.

The base 51 also characteristically has, in correspondence with the lower corners, a pair of run- end elements, or stops, in the form of protruding teeth 63, whose _. function is explained hereunder.

It can be briefly mentioned that the height regulation mechanism comprises a manoeuvring screw 64 which, at the end opposite to the head 65, acts on the upper edge of a shaped slide 66 guided to slide on the base 51.

Said slide 66 ends, below, with at least one hooking element, in the example, two adjacent hooking elements 67 (which can also be merged into a single element) , with horizontal stops 67a (oblique 167a in the embodiment of figures 17-28) which cooperate, as can be clearly seen in the drawings, and as explained hereunder, with a vertical edge 68 of a support 69 (plaque or bar) , fixed to a wall P, to which (the support 69) the wall-cupboard 60 must be firmly hooked.

Figures 13-16 illustrate the depth regulation mechanism (horizontal) of the hanging-bracket 50 in greater detail.

Said mechanism 53 comprises a screw 70, which is screwed onto a base 51 whose end, opposite the manoeuvring head 71, ends with a conical tip 72 acting on the edge 68 of the support 69 (figures 13-16) .

The manoeuvring screws 64 and 70, respectively, of the regulation mechanisms in height and depth, are accessible from above by means of an operating tool U which passes through an opening 73 of the top 59.

Conventionally, when the heads 65, 71 of the screws 64 and 70 protrude from the outer surface of the top 59, this means that the regulations of the hanging- bracket have not been effected (figures 7-10, 23-26), whereas when said heads 65, 71 are contained inside the opening 73, they have been effected.

The functioning of the hidden hanging-bracket produced according to a first embodiment of the invention, illustrated in figures 1-16, is evident from what is described above with reference to the drawings, and is briefly the following.

A wall-cupboard 60 equipped with hanging-brackets 50 produced as shown in figures 1-6, is assembled to the wall according to the sequences of figures 7, 9 by hooking the hooking elements 67 to the vertical edge 68 of the plaque 69 fixed to a wall P, for example by means of expansion pegs (not shown) .

In this situation, the position of both of the regulation mechanisms 52, 53 is with the respective heads 65, 71 protruding from the upper surface of the top 59 (figures 7-10) .

The regulation in height (vertical) , according to the arrows V of figures 9 and 10, of the hanging- bracket, is effected by rotating the screw 64 of the mechanism 52 until the manoeuvring head 65 of the same screw 64 inside the opening 73 in the top 59, grazes the surface of the top 59 itself (figure 11) .

As can be clearly seen in figure 11, in this position, the horizontal stops 67a of the hooking elements 67 of the hanging-bracket are buffered against the horizontal section 74 of the support 69.

With reference to figure 12, if the wall-cupboard 60 is accidently subjected to stress with direct upward forces, as indicated by the arrows F, the teeth 63 (stops) of the hanging-bracket are buffered against the underlying section 75 of the support 69, preventing the hooking elements 67 from becoming disengaged from the edge 68 of the support 69 itself.

This section 65 is opposite to the vertical edge

68.

The upward run which the teeth 63 are allowed to effect, is not in fact sufficient for releasing the hooking elements 67 of the hanging-bracket 50 from the vertical edge 68 of the support 69.

It is therefore evident how, once the height regulation (vertical) has been effected, the components 63, 75 and 67a, 68 act as a vertical run-end of the hanging-bracket .

The regulation in depth (horizontal) of the hanging-bracket 50, in the direction of the arrows 0, is effected as shown in figures 13-16, by rotating the screw 70 of the manoeuvring mechanism 53. In this way, the conical tip 72, by acting on the vertical edge 68 of the support 69, "draws" the cupboard against the wall P, moving it horizontally from the position of figure 13 to the position of figure 15. In this position, the hanging-bracket 50 is completely contained inside the so-called "sanitary space" S.

From figures 13-16, it can also be seen how this regulation in depth does not at all influence the regulation in height previously effected, and consequently the operability of the anti-disengagement device of the hanging-bracket.

Figures 17-28 illustrate a second embodiment of the invention, wherein the same components as those of the first embodiment illustrated in figures 1-16, are indicated with the same reference numbers increased by 100.

As can be clearly seen in the drawings, in this embodiment of the invention, the hanging-bracket 150 is equipped with the regulation mechanism 152 in height (vertical) alone.

The mechanism 152 is assembled in the centre of the base 151 and its functioning is perfectly identical to that of the mechanism 52 previously described with reference to figures 1-16.

Consequently, also in this case, the anti- disengagement device 163, 175, and 167a, 168 becomes automatically operative with the regulation of the mechanism 152, also in the absence of a regulation mechanism in depth (horizontal) .

The objectives mentioned in the preamble of the description have therefore been achieved.

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