Definitions

• This invention refers to a device for opening and retaining leaf doors of pieces of fur- niture, particularly suitable for installation also in pieces of furniture that are not very deep.
• opening and retaining devices for rotating and turn/tilt doors of pieces of furniture are known.
• One device is described in document EP0794309.
• This device consists of a lever connected to the furniture body, preferably to the covering wall, the free end of which slides on a rail on the inner face of the door.
• the lever is activated by an elastic device, such as a gas spring.
• the leaf consists of two folding doors, where the movement of the lower door towards the upper door is guided by at least one slide in a vertical guide fixed to the side wall of the piece of furniture.
• the same device can also be used for leaves with a single door, where the slide and side guide make it superfluous.
• the rod activated by the elastic device is, in this case, formed of two parts joined together and the outermost end of the second part is connected by means of a swivel connection to a fixed member on the inner surface of the door.
• the disadvantage lies in the fact that the positioning of the gas spring and the dimensions of the two parts comprising the rod, are such as to render the device too unwieldy inside the piece of furniture, especially as regards the depth.
• the primary aim of this invention is to provide an extremely compact device for opening and retaining leaf doors, hinged to the covering wall of a piece of furniture, suitable especially for use in pieces of furniture that are not very deep.
• Another aim of the device of the invention is to ensure gentle and silent closing of the doors, and be reliable, ensuring correct working over time without inappropriate backlash as there are no sliding parts.
• Yet another aim of the opening device of the invention is to ensure that it is functional while adjusting the position of the door with respect to the body of the piece of furni- ture.
• This invention proposes to achieve the objectives mentioned above by producing an opening device for leaf door suitable to be mounted on a piece of furniture, wherein said piece of furniture comprises said leaf door, a first wall and a second wall perpendicular to the first wall, said leaf door being at least perpendicular to said second wall and defining a respective rotation axis parallel to the first wall, wherein the opening device defines a respective open and closed positions, the open position corresponding to an open position of the leaf door and the closed position corresponding to a closed position of the leaf door with respect to the piece of furniture, and wherein said leaf door defines in its closed position a predetermined first angle with said first wall, the device comprising a first plate, suitable to be fixed to the second wall, comprising a first fixed pin, a first arm, having a first length, hinged by its first end to the first fixed pin and by its second end to a first mobile pin, a second arm, having a second length, hinged by its first end to the first arm by means of said first mobile pin and suitable to be
• the rod or lever possibly activated by means of an elastic member such as a gas spring, is connected to the door by means of an intermediate oscillating member distinctly shorter than the rod.
• This intermediate member is hinged on one side to the free end of the rod and on the other end to fixing means, fixed rigidly on the inner surface of the door.
• the intermediate oscillating member is sized in such a manner that, when the door is in the open position, the sum of a first distance between the rod ar- ticulation axes and a second distance between the intermediate oscillating member articulation axes is slightly greater than a third distance between the rod articulation axis on the piece of furniture and the intermediate member articulation axis on the door; while the difference of said first and second distances is slightly less than the third distance when the door is in the closed position.
• the intermediate oscillating member constitutes the extension of the rod in the open position, while it is folded up in the closed position, reducing the dimensions of the device of the invention to the minimum.
• the length of the gas spring or another elastic means, in its retracted configuration may be greater or lesser than the rod length, while it is always greater than the length of the intermediate oscillating member.
• the angle formed between the rod and intermediate member, on the side facing the door is slightly more than 0° in the closed position and slightly less than 180° in the position when opened to such a width that the door can oscillate without sticking.
• Said angle between rod and intermediate member is within the range of 10 - 30° in the door closed position, while in the open position, it is in the range of 150 - 170°.
• Another advantage lies in the fact that there are no sliding parts, thereby making the device of the invention less weak, since it is free of backlash and therefore more reliable.
• Use of a known type of decelerator also makes it possible to shut the door of the piece of furniture gently.
• the pivot pin of the intermediate oscillating member on the door is housed on the fixing means of said intermediate member, said fixing means being advantageously adjustable with respect to the door at least vertically, considering a configu- ration with leaf door shut as shown in Fig. 4.
• the fixing means bearing the pivot pin include a mount base for a known type of hinge.
• the mount base is provided with a longitudinal intermediate plate that can be moved by means of a cam and fixed in the desired position. This plate can be advantageously provided with release coupling devices to make it easier to fix an additional plate, suitably provided and connected to the intermediate oscillating member.
• the mount base Thanks to said at least vertical adjustment, made possible by the mount base, possible variations in the device setup and thereby the torque provided by the elastic me- dium can be compensated, for example, when the position of the hinges connecting the door to the piece of furniture is adjusted in relation to the door or parts of the adjacent piece of furniture.
• the correct setup of the device also ensures correct working of the decelerator.
• the hinges connecting the door to the piece of furniture are separate from the opening device. These hinges, normally used for doors with vertical axis, allow adjustment along the three Cartesian axes.
• lateral adjustment with respect to the door with vertical axis makes it possible, in case of leaves, to adjust them vertically and can influence the opening device setup especially in the closing position in such a manner as to modify/optimize the torque provided by the gas spring or another suitable elastic device.

• - possible elastic means 10 such as for example, a gas spring or a simple helical spring
• a leaf door 1 is connected to a covering wall 2 of a piece of furniture by means of a hinge 3, for example, of the articulated quadrilateral type, with the possibility of adjustment along the three Cartesian axes.
• a support or plate 5 provided with a hinge pin or fulcrum 7 for the lever 8 of the device and a pin or fulcrum 9 for fixing one end of gas spring 10 are connected to the side wall 4 of the piece of furniture, by means of screws 6.
• the other end of the gas spring 10 is hinged to a pin 1 1 which forms an integral part of the lever 8.
• the pins or fulcra 7, 9 are fitted in the space between door 1 in the closed position and a flat surface including X, the pivoting direction of the door, as well as the bisector of the angle between covering wall 2 and door 1 in the closed position.
• the position and layout of the holes for fixing support 5 to side wall 4 is such as to allow interchangeability with other similar supports, suitable for fixing different opening devices, for example, suitable for double-leaf doors.
• the lever 8, near the joining area of support 5 with pin 7, has a bracket-like projection 12, forming a right angle with the lever body.
• this projection 12 presses a projecting stem 13 of a known type of deceleration device 14, preferably comprising a cylinder-piston system filled with fluid that is compelled to flow through a throttle valve to obtain a braking effect.
• Gas spring 10 in the leaf closed position exerts a push which creates a moment that acts on the lever in the closing direction.
• the gas spring creates a moment which pushes lever 8 to open the leaf completely open and hold it in this position.
• Lever 8, illustrated in Fig. 2 has at its ends, pivot holes 16, 17 by means of which it is connected in swivel mode to pivot pin 7 of support 5 and pivot pin 18 of oscillating member 19, respectively.
• Said oscillating member 19 is, in turn, connected at its other end by means of articulation 20 to the fixing means on the door, fixed on the in- ner surface of door 1.
• Said fixing means preferably include a mount 21 used for fixing hinges to the sides of a piece of furniture, on which a mount plate 22 is fitted, provided with pivot pin 23 for oscillating member 19.
• the mount 21 is advantageously made up of:
• sub-base 25 that can be fixed by means of screws (not shown in the Figure) to door 1 ,
• the upper plate 30 is provided with front pins 34 which project sideways, lateral truncated-conical stops 35 and a rear hooking tooth 36 oscillating around pin 37 and activated by spring 38.
• Plate 22, connected to intermediate oscillating member 19, has corresponding openings or cavities 40 and 41 for hooking to front pins 34 and side stops 35, respectively, so that these can be hooked in front, by inserting the cavity 40 on pins 34, and rotated backwards so that openings 41 fit around side stops 35 and hooking tooth 36 fits into the rear projections 42 from the top, after being moved backwards from the inclined flat surface 43.
• This configuration of the fixing means al- lows easy coupling of plate 22 to mount 21. However, more economical, less elaborate means such as screw fittings can be used for fixing to the door, as long as adjustment is possible.
• Figures 7 and 8 highlight the effect that adjustment of the door position with respect to the piece of furniture upwards and downwards has on the invention device set up. This adjustment is obtained by means of hinges 3 which make it possible to change the position of the door rotation axes X with respect to the piece of furniture covering wall 2.
• a comparison shows how adjustment of the door upwards brings rod or lever 8 in the closed position closer to door 1 , so that gas spring 10 exerts a lower torque and de- celeration device 14 stem 13 is compressed to a lesser extent.
• Adjustment of the door 1 downwards moves rod 8 farther away from door 1 , stem 13 is compressed completely and the gas spring exerts a higher torque.
• the short dashed lines in Fig. 8 show how the device can be realigned by adjusting plate 22 upwards, so that pivot pin 23 shifts in the position 23' and pivot pin 18 moves to position 18' corresponding to the device position shown in Fig. 4.
• Position 18' is identified by the intersection of arches 50, 51 ', defined by oscillation of lever 8 with respect to pivot pin 7 and oscillation of pin 18 with respect to pivot position 23', respectively.
• Arch 51 is defined by oscillation of pin 18 with respect to pivot pin 23.
