Definitions

• the present invention refers to a concealed and adjustable mounting device, with improved fixing system to the top corner of wall-furniture- Mounting devices of this type (also commonly called concealed furniture attachments) are, for example, described in EP 555.924, EP 1.008.316 and DE 201 03 728, to which we refer should possible further clarification be necessary on the general structure of said devices, on their specific purpose and operation.
• a mounting device of the type described in EP 1.008.316 and DE 201 03 728 is structurally formed from a metal plate, in a single elongated piece, having a plurality of attachment pins which extend from a side thereof.
• the mounting device described in EP 555.924 also has a plurality of holes for attachment screws on the opposite side to said pins.
• the plate is intended to be fixed to the top corner of the furniture, and possibly also to the top wall
• Said dowel extends from the same side as the pins, substantially lying on the same plane, and is rotatable (substantially by 180°) between a non-operative position, of insertion thereof in a respective seat of the top corner of the furniture, and an operative position in which teeth, or attachment ridges thereof, engage stably in said seat, gripping the body of the furniture.
• the rotation of the dowel is controlled manually through a lever which, in non-operative position, is contained inside the plate of the mounting device whereas, in operative position, it extends, for a certain portion, beyond the lower end of the plate itself.
• the general purpose of the present invention is that of avoiding the drawbacks of the prior art, realising a concealed mounting device of the type mentioned above, equipped with positive attachment means (in addition to the pins) , capable of ensuring stable and secure attachment through time of the mounting device to the furniture, where it is impossible to operate on said attachment means, voluntarily and accidentally, in the direction to cause a partial or total withdrawal of the plate of the mounting device from the top corner of the furniture.
• figure 1 is a top front view illustrating a non- limiting example of a concealed mounting device realised according to the invention
• figure 2 is a section view taken according to the plane line II-II of figure 1
• figure 3 is a top side view according to the arrow F of figure 1
• figures 4 and 5 illustrate the mounting device of figures 1-3 fixed to wall-furniture, where said wall- furniture is only partially illustrated, and in figure 5 is hung on the wall
• figures 6-8 are details in section illustrating the ways of positive attachment of the mounting device to the top corner of the furniture using the attachment means according to the present invention
• - figures 9-15 are details illustrating the stable mounting system on the plate of the mounting device of the positive attachment means according to the invention, where figure 14 is an enlarged section taken according to the plane line XIV-XIV of figure 1; and figure 16 is a figure
• the mounting device according to the invention is wholly indicated with 20, and is structurally formed from the combination of a plate 21, having a substantially elongated rectangular configuration, and an arm 22 fixed to said plate 21 in an articulated way.
• the head of the screw 31 consists of a first gearing 32 coupled at 90° with a second gearing 33, which has, on the opposite side to the teeth, a seat 34 for a manoeuvring screwdriver.
• Concealed adjustable mounting devices of the type described above are fixed to the top corner 23 of the wall furniture (manually or even automatically) , by inserting ⁇ , with interference" the pins 27 in respective seats 43 of the top corner 23 (figures 4, 6-8 and 16) .
• the pins 27, however, are not able to ensure the stable and secure attachment through time of the mounting device to the top corner of the furniture. Indeed, as better explained in figure 16, when the wall-furniture is hung on the wall, its weight generates a force 44 on the arm 22 which tends to make the mounting device rotate in the direction of the arrow 61 about the point P, generating a reaction force 45 which tends to pull the pins 27 out from the top corner 23 of the furniture.
• the plate 21 has, in addition to the pins 27, the aforementioned positive attachment means 28.
• said positive attachment means 28 comprise a tubular dowel 46, for example made from plastic, or else metal, consisting of interspaced circumferential partitions 47, radially yielding in an elastic way, and having annular anchoring teeth 48 (figures 6-8) .
• Said dowel 46 also has an annular anchoring throat 49 in a corresponding cradle seat 50 of the plate 21 (figures 9-11), which is aligned with an opposite and interspaced hole 55 (oval or deformed in another way) , of the plate 21 itself.
• an actuator member in the form of a metallic expansion pin 51, comprising two sections 52, 53 with a shorter and longer diameter respectively, cooperates with said tubular dowel 46,
• the diameter of the longer section 53 is substantially equal to the inner diameter of the tubular dowel 46.
• the expansion pin 51 is inserted coaxially (passing through the hole 55) inside the tubular dowel 46 until the free end of its section 53, with a longer diameter, is brought into abutment against a breakable transversal diaphragm or partition 54 of the dowel 46 itself.
• the section 52 with a shorter diameter of the pin 51 is, on the other hand, anchored to the hole 55 of the plate 21, with the possibility of axial translation.
• the elastically yielding partitions of the dowel 46 flex inwards, as shown in figure 7.
• the expansion pin 51 can be introduced (driven) inside the dowel 46 with consequent breaking of the partition 54, thus causing the expansion of the partitions 47 and the penetration of the annular teeth 48 in the solid body of the top corner 23, which leads to the stable and irremovable attachment of the mounting device.
• Figures 9-15 illustrate the possible assembly steps of the dowel 46 and of the relative expansion pin 51 on the plate 21.
• the dowel 46 and the expansion pin 51 have a seat between two opposite parallel walls 57, 58 formed integrally from the plate 21, which respectively have the cradle 50 and the hole 55 for housing the dowel 46 and the section 52 of the expansion pin 51.
• the assembly steps are the following.
• the dowel 46 is housed with its anchoring throat 49 in the cradle 50 (figures 9, 10) , after which the pin 51 is inserted as shown in figures 11-13.
• the pin 51 is held in position, with the possibility of axial sliding, through deformation (in the direction of the arrow) of the hole 55, as shown in figures 12-15. It should be noted that (figure 12), in the assembled position, the section 53 of the pin 51 rests upon the base 62 of its seat, so as to ensure a correct translational movement into the position of figure 8.
• the horizontal and vertical adjustment systems of the mounting device according to the invention have been illustrated as a non-limiting example, with them being able to be of a different type, provided they can be combined with the attachment system 28, which is the essence of the invention itself.
