Description

This invention relates to a drive device for furniture fittings, in particular fittings for turning cabinet furniture flaps, comprising a housing attached to a piece of furniture, on which or in which an electric motor is provided, by means of a transmission actuating a connecting element connected to the furniture part.

There is furniture fittings driven by an electric drive. In this case, the drive is usually individually adapted for the corresponding element of the fittings and is intended for a specific application. This increases the cost of manufacture, since in most cases you can sell only a limited number of certain accessories with a drive. It is with regard to furniture turning furniture that there is a problem in that it is desirable to have a drive, since this furniture is usually suspended high in cabinet furniture, and opening and closing of furniture turning is perceived as a difficult action.

In this regard, the objective of the invention is to create a drive device for furniture fittings, in particular, fittings for turning the leaves of cabinet furniture, universally applicable to various pieces of furniture and at various mounting positions on the cabinet of a piece of furniture.

This problem is solved thanks to the drive device with the characteristics of paragraph 1 of the claims.

In accordance with the invention, a connecting element connected to the hardware part is mounted centrally in the housing in a direction perpendicular to the plane of movement of the hardware part, and a drive device for actuating the hardware to rotate the leaves can be installed on opposite sides of the furniture body. Thus, the drive unit can be installed universally on the furniture body - either on the right or on the left side, which allows to reduce inventory. Due to the universal possibility of connecting the connecting element, the drive unit can also be used with a large number of various fittings, so this drive unit can be equipped with fittings that are already installed in furniture.

According to a preferred embodiment of the invention, the connecting element is made in the form of a lever passing through a central groove in the housing. As a result, the components of the drive device in the housing can be largely protected from dirt and other environmental influences.

For mounting the drive device, the connecting element can be mounted rotatably on the pivotable swing arm, so that when installing the housing of the drive device, certain tolerance compensation can be made.

To specify the range of rotation of the parts of the fittings, limit switches can be provided by means of which the electric motor can be turned off after reaching the maximum opening or closing position. Preferably, the limit switches can be actuated by at least one leash mounted on the pivot arm. Using leashes and / or limit switches, you can adjust the rotation range of the pivot arm so that this adjustment allows you to change the range of rotation of the fittings. This makes it possible to adjust accordingly depending on the purpose of the drive device.

According to a further embodiment of the invention, the electric motor is connected to a controller that is connected to a signal wire and / or remote control with a switching device. Thus, with the help of the controller, the hardware part can be opened and closed, if necessary, and the switching device does not have to be located right next to the furniture body; remote control or remote switching from a certain distance is also possible.

For an efficient drive, the pivot arm has teeth that mesh with the gear. If the transmission has an appropriate gear ratio, then the electric motor can be made relatively small.

The drive device on the connecting element is preferably connected to fittings for turning the sash. In this case, depending on the design size of the leaf, the corresponding drive device on the hardware can be mounted both on the right and on the left side. In case of less weight, it may be sufficient to install only one drive unit on the hardware.

Below the invention is explained in more detail based on an example implementation and with reference to the accompanying drawings. The drawings show the following:

Fig.9. a top view of a drive unit with fittings for turning the leaves is shown.

figure 10 in a perspective view shows a rear view of the fittings for turning the shutters with a drive device.

Figure 1 shows a drive device for fittings 1 for turning the leaves, which by means of a mounting plate 2 can be attached to a piece of furniture, preferably to pieces of furniture such as cabinets. The fitting 1 for turning the flaps comprises a turning part 4 on which a plate 3 is made for connection with the flap. The pivoting part 4 is angular and in section 5, perpendicular to the plane of the plate 3, has a hinge axis 6 on which the guide lever 7 is mounted. At a certain distance from the axis 6, another axis 8 is made in section 5, on which the second guide lever 9 is mounted for rotation .

At the end directed from the rotary part 4, the guide lever 9 is connected via an axis 10 to the first lever 11, which on the axis 15 is also pivotally connected to the guide lever 7. At a certain distance from the first lever 11 mounted on the mounting plate 2 on the axis 17, a second lever 12 is provided, which is pivotally connected to the guide lever 7 via the axis 13, and from the other end via the axis 14 to the mounting plate 2.

As shown in FIGS. 2 and 3, the pivot 4 can be rotated relative to the mounting plate 2. In the case of the fittings 1 for turning the flaps shown in these drawings, we are talking about fittings with seven hinge axles 6, 8, 10, 13, 14, 15 and 17. The location of these axes, as well as the geometry of the levers 7, 9, 11 and 12, may vary depending on the application.

For easier movement of the rotary part 4 to the open position, a spring 25 is provided, which is mounted at one end on an axis 24, forming the center of the hinge for the lever 21 and the lever 22. The lever 21 is mounted to rotate on the hinge axis 13, and the lever 22 from the side the opposite axis 24, is attached to the axis 23 provided on the mounting plate 2. On the side opposite to the axis 24, the spring 25 is attached to the pin 26, which is mounted with the possibility of adjustment on the screw 27, so that you can adjust the spring tension.

In the closed position of the leaf 3, the spring 25 presses the rotary part 4 into the closed position, since to open the rotary part 4 by means of a mechanism, the levers 21 and 22 are first moved to each other by axes 13 and 23, the length of the spring 25 initially slightly increases. Only after reaching a certain angle, for example from 15 ° to 25 °, the length of the spring decreases, and the spring 25 pushes the rotary part 4 to the open position. Thus, after passing the dead center, the opening stroke is supported by the spring 25.

So that the hardware can be opened and closed not only manually, but also automatically, a drive device is provided. The drive device comprises a connecting element 30 in the form of a lever, which is mounted on the hinge axis 13 on one side and on the axis 35 on the pivot arm 33. On the opposite side, the pivot arm 33 is rotatably mounted about the axis 34. The pivot arm 33 has a gear sector 31 cooperating with a gear wheel of a transmission 32 formed by several gears. The gear wheel 36 of the transmission 32 can be driven by the drive shaft 37 of the electric motor 38. Thanks to the transmission 32, a gear ratio is provided, therefore, the electric motor 38 can be made of a relatively small size.

On the pivot arm 33, two spacers 42 and 44 are spaced apart, by means of which the corresponding limit switch 40 or 41 mounted on the housing can be turned off so that the electric motor 38 can be switched off by the controller.

To open the pivoting part 4, the electric motor 38, by means of the transmission 32, drives the pivoting lever 33 counterclockwise until the first half-open position is reached (Fig. 2), and then the fully open position (Fig. 3) is reached. In the maximum open position, the lead 42 presses on the contact lever 43 of the limit switch 40, which turns off the motor 38. If the rotary part 4 again moves to the closed position, then the lead 44 presses on the contact lever 45 of the second limit switch 41, therefore, in the extreme position, the motor 38 turns off . Leashes 42 and 44 and / or limit switches 40 and 41 can be adjusted to set switching points. For this, elongated holes 46 are made in the housing 50 or the circuit board, in which screws 47 are inserted to secure the limit switches 40 and 41. By changing the position of the screws 47, the limit switches 40 and 41 can be fixed in the required position.

The drive device is housed in a housing 50 consisting of two halves 51 and 52, the housing 50 may also have more than two parts. An electric motor 38, a gear 32 and a pivot arm 33 are installed in the housing 50. A connecting element 30 is provided from the central groove, which is made in the form of a lever and connected on the axis 13 with a guide lever 7 of the hardware for turning the wings.

As shown in Fig. 8, the connecting element 30 is located in the housing 50, the halves 51 and 52 of the housing forming a groove for the input of the connecting element 30. The gap between the connecting element 30 and the outside on both sides is equal to size A. Due to this, the drive device can be fixed both on the right side and on the left side of the furniture. To do this, you only need to provide one type of drive unit for both sides of the fittings, and the drive unit can be used universally for other fittings. For this, it is also possible to coordinate the rotation range of the pivot arm 33, for example, by differently positioning the leads 42 and 44. Alternatively, you can also change the position of the limit switches 40 and 41.
