"MOBILE AND HINGE FOR THE SAME"

DESCRIPTION

The invention refers to a piece of furniture of the type of a wardrobe, with at least one door which is articulated, by means of two hinges, to a wall of the piece of furniture or to a frame of the piece of furniture, a damping device being provided for the damping of the door movement.

Furthermore, the invention relates to a hinge to be used in such a piece of furniture.

It is known to provide hinges, by means of which the doors of a piece of furniture are articulated on a side wall of the piece of furniture or on a frame of the piece of furniture, with a closing device which presses the door into its closed position. The locking device consists of a spring.

It is also known to provide such hinges with a damper, with which the doors are to be prevented from slamming.

The object of the invention is to improve a piece of furniture of the type indicated above, in the sense of making it possible for the closing and damping forces to better respond to the respective requirements.

The object of the invention is achieved thanks to the fact that at least one of the hinges is shaped as a mere damping hinge and at least one of the hinges is shaped as a spring hinge which has a closing device, but not a damping device.

An embodiment of the invention provides that, above and below a damping hinge without a closing device, there is in each case at least one spring hinge with a closing device, but without a damping device. In this way, a safe and stable joint of the sash is obtained, with good damping.

The invention provides that the damping hinge arm is mounted so that it can move freely relative to the base plate. Advantageously, the hinge arm can be overturned on the base plate, or on the intermediate piece, and is mounted in such a way as to be able to slide into the depth of the cabinet.

Due to the loose and movable support of the damping hinge arm it is possible that, during the adjustment of the sash position, what takes place by adjusting the position of the hinge arms on the base plates of the spring hinges, the hinge arm of damping automatically assumes the correct position. In other words, if the spring hinge arms are moved in the direction of the furniture joint and the depth of the furniture, the damping hinge arm is pulled into movement.

The conformation of the damping hinge according to the invention has another advantage. There are four hinges with pivot points with opening angles of different widths, for example 125 °, 110 ° and 90 °. Each of these hinges is characterized, during the closing and opening movement of the door, by a specific movement trend. Therefore, it is normally only possible to anchor a door with hinges having the same opening angle to the body of the piece of furniture. On the other hand, the damping hinge according to the invention can always be used, regardless of whether the spring hinges have an opening angle of 120 °, 110 °, or 90 °. Various embodiments of the invention are described below, on the basis of the figures of the attached drawings.

Unlike traditional furniture; in which the furniture door is fixed to a wall of the furniture by means of several hinges of a type, the door 12 of the furniture according to the invention of Figure 11 is fixed to the side part 11 of the furniture by means of a damping hinge 10 and a spring hinge 20, which has a closing device.

In the embodiment example according to Figure 2, the door 12 is mounted on the side wall 11 of the cabinet by means of two spring hinges 20, which are hinges without a damping device but with a closing device, and by means of a damping hinge 10 , therefore, a hinge having only a damping device, but not a closing device.

Both the damping hinge 10 and the closing hinges 20 have a hinge cup 1, which is inserted in a hole in the door 12, and a hinge arm 2 which is mounted on the side door 11 of the piece of furniture, by means of a 7 base plate.

The hinge arm 2 and the hinge cup 1 are joined to each other by means of an external toggle lever 3 and an internal toggle lever 4, which are supported on articulation axes 5, 6 of the hinge arm 2 and cup 1 of the hinge.

In the exemplary embodiment shown, a so-called dead center hinge is used as the spring hinge 20. This has a torsion spring 8 which presses, with its arm 8 ', on a pin 9 of the internal toggle lever 4, protruding in the arm 2 of the hinge and, with its second side 8' ', on an articulation axis 6, by means of which the external toggle lever 3 is mounted in the cup 1 of the hinge. The leaf 12 is pressed, by the torsion spring 8, both in the closed position and in the open position.

Instead of the sprung hinge 20, shown in Figures 13 and 14, a sprung hinge could also be used which moves the door 12 only in the closed position.

Figures 3 to 9 show various embodiments of the damping hinges 10.

In the embodiment example according to Figure 3, a liquid damper 9 is fixed on the hinge arm 2, which is shaped as a piston-cylinder unit, with a fixed cylinder 13 and a piston with rod 14, sliding in a linear direction. A head 15 is fixed to the free end of the rod 14 on which, during the closing of the leaf 12, the cup 1 of the hinge presses with its flange 19. The damping means of the cylinder 13 can be as much air, a gas, as much as a liquid, for example a silicone oil. By means of the damping means, during the closing of the leaf 12 the movement of the piston of the cylinder 13 is braked and the closing movement of the leaf 12 is damped.

A spring is preferably provided on the cylinder 13 which presses the piston, during the opening of the leaf 12, again in the emergency position shown in Figure 3.

In the embodiment example according to Figure 4, two rotary dampers 16 are mounted on mutually opposite sides on the outer wall of the cup 1 of the hinge. The rotary dampers 16 have axes 21 which penetrate inside the bowl 1 of the hinge and on which a lever arm 26 is mounted.

If the leaf 12 is closed, the external toggle lever 3 presses on the arm 26 of the lever which connects the cup 1 of the hinge to the arm 2 of the hinge, and the closing movement of the leaf 12 is slowed down. If the door 12 is opened, a spring 27 located on the bottom 28 of the hinged cup 1 presses the arm 26 of the lever back into the emergency position. The rotary dampers 16 are designed as liquid dampers and have a rotary piston arranged in the housing, with a damping liquid - preferably silicone oil - between the rotary piston and the housing wall.

In the embodiment example of Figures 5 and 6, the rotary damper 16 is mounted on the arm 2 of the hinge.

The rotary damper 16 is provided with at least one pinion 18 which meshes with a toothed profile 23 which is formed on an arm 22 of the internal toggle lever 4, oriented towards the inside of the hinge arm 2. If the leaf 12 is opened or closed, by effect of the movement of the internal toggle lever 4 the pinion 18 is set in rotation, and with it the rotating piston in the rotating damper 16, and the closing movement is damped, or respectively of door opening 12. Damping can take place for the entire opening angle of the hinge, or only for a limited area. The rotary damper 16 can also be equipped with a unidirectional device, so that no damping effect occurs when the leaf 12 is opened.

Figures 7 to 9 show a damping hinge 10 in which the closing movement of the leaf 12 is damped in the last zone of the closing path and the opening movement in the last zone of the closing path. In the middle, the door 12 can swing freely.

In the exemplary embodiment shown, a rotary damper 16 is preferably arranged on the outside, on each side of the cup 1 of the hinge.

A lever arm 26 in the form of a bracket, which is located inside the cup 1 of the hinge, is engaged on the rotor of the rotating dampers 16, as in the embodiment example according to Figure 4.

For a large part of the closing movement of the sash 12, the damping hinge 10 can freely rotate. The rotary dampers 16 do not go into action.

If the damping hinge 10 is closed, the external toggle lever 3 presses, as can be seen in Figure 7, the bracket-shaped lever arm 26 in the direction of the bottom 28 of the hinge cup 1, whereby they come into operation 16 rotary dampers. The door 12 then closes smoothly, even if it has been closed too forcefully by the user.

In the cup 1 of the hinge there is again provided a torsion spring 27 which, when the hinge is open, presses the arm 26 of the lever back into the emergency position.

Another rotation damper 16 is housed in the arm 2 of the hinge. This rotary damper 16 has a substantially triangular housing 17 which adheres, with a wall, to the central rib 21 of the arm 2 of the hinge. In the example of embodiment shown, the rotary damper 16 is equipped with two toothed wheels 18 which are each located inside, next to a lateral rib of the arm 2 of the hinge.

The internal toggle lever 4 has, as in the embodiment according to Figures 5 and 6, two rearwardly oriented arms 22, on each of which teeth 23 are formed.

If the leaf 12 is opened, it can again move freely for a large part of the opening angle. Only when the leaf 12 has reached the position shown in Figure 8, the teeth 23 of the internal toggle lever 4 engage in the toothed wheels 18 of the rotating damper 16 and a rotational movement of the leaf 12 is damped until it has reached the extreme open position shown in figure 9.

The rotary dampers 16 in the hinge arm 2 and the hinge cup 1 may be provided with a one-way joint, in that direction in which damping is not required.

Figures 4 and 10 to 12 show a particular assembly according to the invention of the arm 2 of the damping hinge 10 on the base plate 7.

The arm 2 of the hinge is mounted, by means of an intermediate piece 24, on the base plate 7. The intermediate piece 24 has, in the traditional way, an anchoring pin 29 developed transversely between the two lateral ribs 25 of the intermediate piece 24. The pin 29 can be attached behind a projection at the forward end of the base plate 7.

At the rear end, the intermediate piece 24 is equipped with a rocker lever 30 which has a fixing projection 31 which, in the assembled position, penetrates a notch 32 of the base plate 7. This type of fixing of the intermediate piece 24 on the base plate 7 is described in the international patent application WO 97/22773 of the Applicant.

The assembly of the hinge arm 2 on the intermediate piece 24 is new and in accordance with the invention, and precisely the hinge arm 2 is mounted on the intermediate piece 24 so as to be able to overturn and to be able to slide freely in the depth of the cabinet. The arm 2 of the hinge has, approximately in its center, a support tip 33 which is oriented parallel to the axis of rotation of the hinge and which extends from one lateral rib to the other of the arm 2 of the hinge. This support tip 33 penetrates, through a slot 34, into the intermediate piece 24. There is no set screw. The arm 2 of the hinge can be made to slide freely in the direction of the depth of the cabinet, along the long side of the slot 34.

The tilting movement of the hinge arm 2 is further facilitated by the fact that the intermediate piece 24 is made with a convex surface 35 on its side facing the central rib of the hinge arm 2. The support according to the invention of the arm 2 of the hinge on the intermediate piece 24 has the advantage that, during the adjustment of the position of the leaf 12, this takes place by adjusting the position of the arms 2 of the hinge on the base plate 7 of the hinges 20 spring, the arm 2 of the damping hinge 10 automatically assumes the correct position. In other words, if the arms 2 of the sprung hinges 20 are made to slide in the direction of the furniture joint and the depth of the furniture, the arm 2 of the damping hinge is dragged in the movement.

Preferably, the arm 2 of the damping hinge 10 has an internal diameter which, as shown in Figure 12, is greater than the width of the intermediate piece 24. In this way it is also possible to adjust the position of the hinge arm 2 with respect to the base plate 7, also in the direction of the height of the piece of furniture.

Since the damping forces, when closing or opening the sash 12 respectively, are absorbed in the damping hinge 10, between the hinge arm 2, the toggle levers 3, 4 and the hinge cup 1, it is not necessary fix the arm 2 of the hinge to the intermediate piece 24.

The adjustment of the position of the arms 2 of the sprung hinges 20 takes place in accordance with the known state of the art.
