DESCRIPTION

Drive device for hardware

The present invention relates to a wardrobe according to the preamble of revindication 1.

There are furniture fittings that are movable by an electric drive. In this case, the drive is adapted to the respective hardware and designed for a special purpose of use. This increases manufacturing costs, since it is only possible to distribute a limited amount of certain driven hardware. Precisely, for the sector of the folding fittings the problem is that a drive is convenient, since in furniture closets the folding fittings are, most of the time, arranged vertically in the wardrobe furniture and the opening and closing of the hardware of Swing are perceived as industrious.

Document GB 1 398 732 discloses a drive device for drawers or doors in which an electric motor drives a movable spindle nut along a spindle. The spindle nut moves a slide that is coupled by means of a lever or drag for the activation of the hardware.

WO 2005/021914 shows an opener in which a spindle is operated by means of a motor to move the pivoting lever. The lever has at its end a rotating roller that rests on a door plate, so that the door can be opened.

EP 361 020 discloses a retention mechanism for a tailgate of a vehicle in which the tailgate can be fixed in a certain position by means of a double action cylinder and a drive mechanism.

Accordingly, the objective of the present invention is to create a wardrobe with a furniture body, a hinged hardware and an improved actuation device for the hinged hardware.

According to the invention, said objective is achieved by means of a wardrobe with the characteristics of claim 1.

According to the invention, the drive device can be mounted on opposite sides of the furniture body for the operation of the swing hardware. In this way, the drive device can be universally mounted for a right or left side of the furniture body, which reduces the maintenance of a stock. By means of the universal possibility of connecting the coupling element, the drive device can also be used for a number of different hardware, so that the hardware already installed in furniture can be retrofitted with the drive device.

According to the invention, the coupling element is configured as a lever that crosses a slit of the housing. In this way, the components of the drive device in the housing can be extensively protected from fouling and other environmental influences.

For a mounting of the drive device, the coupling element may be rotatably mounted on a pivoted lever operated, so that a certain tolerance compensation can be performed during assembly of the drive device housing.

In order to specify the turning range of the hardware parts, limit switches can be provided by means of which the electric motor can be disconnected when reaching a maximum opening position or a closing position. In such a way, the limit switches are preferably operated by means of at least one drive mounted on a pivoting lever. In such a way, the turning range of the pivoting lever can be adjusted by means of the drag and / or the limit switch, so that, indirectly, the turning range of the hardware is modified by means of the adjustment . This allows an adjustment corresponding to the purpose of use of the drive device.

According to another configuration of the invention, the electric motor is coupled with a control that is connected by a signal line and / or a remote control is connected to a control device. In this way, the hardware can be opened and closed according to need by means of the control, it being not necessary that the control device is arranged directly adjacent to the furniture body, but also a remote control or remote control is possible through a certain distance.

For an effective drive, the pivoting lever has a gear that is engaged with a wheel

gear toothed. When the gear has a certain relationship, the electric motor can be designed relatively small.

The drive device is connected in the coupling element with the hinged fitting, the same being applied to the opening of a pivoting door. In such a way, a corresponding drive device can be mounted, according to the size, on the door to the swing fitting, both on the right side and on the left side. For smaller weights it may be sufficient that only one drive device is mounted on the swing hardware.

Next, the invention is described in detail by an example of realization with reference to the attached drawings. They show:

Figures 1 to 3, side views of a drive device mounted on a hinged fitting in different opening positions;

Figure 4, a perspective view of the pivoting hardware with the drive device of Figure 1; Figures 5 to 7, different views of the drive device and the hinged fitting with closed housing;

Figure 8, a front view of the drive device;

Figure 9, a top view of the drive device with the hinged fitting, and

Figure 10, a rear perspective view of a hinged fitting with a drive device.

Figure 1 shows an actuation device for a hinged hardware 1 which, by means of a retention plate 2, is mounted to a furniture body of a wardrobe. Swing hardware 1 includes a pivoting part 4 in which a plate 3 is provided for joining with a cover. The pivoting part 4 is angularly configured and presents in a section 5 perpendicular to the plane of the plate 3, an articulation axis 6 on which a gliding lever 7 is mounted. Separated from the axis 6 is configured in section 5 another axis 8 on which another glutton lever 9 is rotatably mounted.

The glide lever 9 is at the far end of the pivoting part 4 connected by means of an axis 10 with a first lever 11 which in the same way is articulated with the glutton lever 7 on an axis 15. Distanced from a first lever 11 mounted on the retaining plate 2 on an axis 17 a second lever 12 is provided which is connected on one side by means of the axis 13 with the glide lever 7 and on the other end, articulated, by means of an axis 14 with retaining plate 2.

As can be seen in Figures 2 and 3, the pivoting part 4 can be pivoted with respect to the retaining plate 2. The swinging hardware 1 shown is a fitting with seven articulated axes 6, 8, 10, 13, 14, 15 and 17. The arrangement of these axes, as! Like the geometry of the lever 7, 9, 11 and 12, it can be varied according to the case of application.

In order to be able to move the pivoting part 4 more easily to the opening position, a spring 25 is provided which is mounted at one end to an axis 24 that forms an articulation point for a lever 21 and a lever 22. The lever 21 it is pivotally mounted to the articulation axis 13 and the lever 22 is fixed, away from the axis side 24, on an axis 23 which is provided on a retaining plate 2. On the side separated from the axis 24, the spring 25 is fixed to a pin 26 held in an adjustable screw 27 to adjust the spring tension.

In the closed position of the door 3, the spring 25 presses the pivoting part 4 to the closed position, because for the opening by means of the mechanism of the pivoting part 4, the levers 21 and 22 are, firstly, approximated to each other by axes 13 and 23, so that the length of the spring 25 is enlarged somewhat more at the beginning. Only after an angle of about 15 ° to 25 ° the spring length is reduced and the spring 25 now presses the pivoting part 4 to an open position. Therefore, after overcoming a neutral, the opening movement is supported by the spring 25

So that the hinged hardware can not only be opened and closed manually but also automatically, a drive device is provided. It includes a coupling element 30 in the form of a lever that is mounted on one side to a pivot lever 33 on the articulation axis 13 and on the opposite side on an axis 35. The pivot lever 33 is rotatably mounted on an axis. de rotation 34. The pivot lever 33 has a gear section 31 engaged with a gear wheel of a gear 32 composed of multiple gear wheels. A gearwheel 36 of the gear 32 can be driven by a drive shaft 37 of an electric motor 38. The gear 32 offers a multiplication, so that the electric motor 38 can be made comparatively small.

In the pivoting lever 33, two sliders 42 and 44 are provided spaced apart, by means of which

limit switches 40 and / or 41 mounted in a housing can be controlled, so that the electric motor 38 can be disconnected by means of a command.

To open the pivoting part 4, the electric motor 38 drives the pivoting lever 33 by means of the gear 32 counterclockwise, until, in the first place, an open half position is obtained (figure 2) and then a fully open position (figure 3). In the maximum open position, the drag 42 presses against a contact arm 43 of the limit switch 40 that disconnects the electric motor 38. If the pivoting part 4 is moved back to the closed position, the drag 44 presses against an arm of contact 45 of the second limit switch 41, so that the electric motor 38 is disconnected in the final position. The draggers 42 44 and / or the limit switches 40 and 41 can thus be adjusted to adjust the switching points. For this, longitudinal holes 46 are configured in a housing 50 or a mounting plate in which screws 47 are inserted for fixing the limit switches 40 and 41. By displacing the position of the screws 47 it is possible set the limit switches 40 and 41 to the desired position.

The drive device is housed in the housing 50 which is composed of two housing halves 51 and 52, the housing 50 being able to also have more than two parts. In the housing 50 the electric motor 38 is mounted with the gear 32, as! as the pivoting lever 33. The coupling element 30 which, on an axis 13 is connected to the gliding lever 7 of the hinged fitting, protrudes from a central opening.

As can be seen in Figure 8, the coupling element 30 is located in the housing 50, the housing halves 51 and 52 being configured a gap for the passage of the coupling element 30. The spacing of the coupling element 30 towards the outer side It is the measure A on both sides. In this way it is possible to fix the drive device both on a right side of the furniture body and also on the left side of the furniture body. It is only necessary to have one type of drive device for both sides of the swing hardware, and the drive device can also be applied universally for other hardware. For this, an adjustment of the rotation range of the pivoting lever 33 can also be made, for example by positioning the sliders 42 and 44 differently. Alternatively, it is also possible to vary the position of the limit switches 40 and 41.
