Similar parts in the various embodiments of the invention are indicated using the same reference numerals.
The control device for performing the opening or closing phase of the dynamic part on the static part of the furniture, indicated as a whole with the reference number 1, acts at least on the spring means for controlling the opening or closing phase. It consists of a single electric motor 3 and in particular a ratchet 4 of a known type (and therefore not described in detail here) of a spring (not shown).

Furthermore, operating means for the electric motor are provided which are activated during the opening or closing phase.
Specifically, the electric motor 3 is suitable for applying a load to the spring of the ratchet 4 only in the opening stage.

  In the first solution (FIGS. 1 to 6), the second solution (FIGS. 7 to 12), and the fourth solution (FIGS. 18 to 20), the dynamic part of the furniture is fixed to the drawer. On the other hand, the static part consists of a fixed guide 15 fixed to the static body of the furniture, slidably associated with the movable guide 2.

In the third solution (FIGS. 13 to 17), the dynamic part of the furniture consists of a static part, for example a universal door 82 connected to the side panel 85 or a drawer front plate.
In the first solution (FIGS. 1 to 6) and the second solution (FIGS. 7 to 12), any type of electric motor 3 is attached to the fixed guide 15 and the spindle of the electric motor 3 is fixed. 14 is suitable for moving along an axis parallel to the sliding of the extraction guide 2.

  The ratchet 4 is coaxially arranged with respect to the electric motor 3 on the fixed guide 15, and is further held in the vicinity of the main body of the ratchet 4, or protruded therefrom, to the stopper 17. By acting, the head 16 is adapted to be moved by its action against the spring inside the ratchet 4 so that the drawer is opened by sliding outwardly of the withdrawal guide 2 integral with the stop 17. Is provided.

  Suitably, as can be clearly seen by the example in FIG. 2, the ratchet 4 is arranged coaxially with respect to the spindle 14 and the head 16 of the ratchet 4 is transverse to the movement axis L of the head 16. (Laterally) has a projecting portion 80 that allows the head 16 to engage the stop 17 disposed on the withdrawal guide 2 as described above.

In the opening phase of the drawer, for example, the ratchet 4 is activated by applying pressure directly or indirectly to the head 16.
At this stage, this pressure releases the head 16, which acts on the stop 17 by means of a spring, giving the pulling guide 2 a force that allows the drawer to be partially opened, which is then used It will be fully opened manually by a person.

The step of pressing the head 16 of the ratchet 4 is shown in FIG.
FIG. 4 shows the maximum projecting position of the head 16 from the ratchet 4, after the head 16 contacts the spindle 14 after applying sufficient thrust to the extraction guide 2 to partially open the drawer. The operation signal of the electric motor 3 is generated.

  As can be seen in FIG. 5, at this point the electric motor 3 is activated and the spindle 14 protruding from the motor unit moves away from the electric motor 3 and presses the spring, causing the head 16 of the ratchet 4 to move. , Retract it to a position where you can block it.

As shown in FIG. 6, when the spindle 14 returns the ratchet 4 to the initial position, the spindle 14 returns toward the motor unit, causing the ratchet to reach the initial rest position.
At this stage, the ratchet 4 is re-loaded and the electric motor 3 is in the rest position, while the extraction guide 2 is protruding and the stop 17 has moved beyond the electric motor 3 and is therefore Allows the operator to manually open the drawer completely.

In the drawer closing phase, the following steps are performed in succession.
In a suitable position under the withdrawal guide 2, the fixed guide 15 comprises a pull-out self-closing device 29 of the generally known type, inside the self-closing device 29 there is a tension spring 20 and in the molded guide. There is a slidable mounting element 21.

  During the drawer closing phase, the withdrawal guide 2 tends to return to its initial position, and its integral dragging pin 22 engages the attachment element 21 so that it is received. The pin 22 is allowed to drag away by a spring 20 that stresses the mounting element 21 away from the body 23 that is being moved and towards the closed position.

  When the spring 20 is partially unloaded and the stop 17 is in contact with the head 16 of the ratchet 4, the spring of the head 16 of the ratchet 4 is loaded again and the mounting element 21 is pin 22 Is moved to the end of its travel distance, where the drawer is in the closed position.

The entire system is ready to be used again to open the drawer by applying additional pressure.
The second solution (FIGS. 7-12) is only the addition of a known type of decelerator 30 that is suitable for decelerating drawer closure (FIGS. 1-6). ) Is different. Thus, this operation does not cause noise or other drawbacks due to sudden impacts between the drawer and the furniture.

In this case, the speed reducer 30 is mounted coaxially with respect to the electric motor 3 and the ratchet 4 on the fixed guide 15, but the speed reducer 30 may be disposed at any other suitable position.
A second stop 31 extending in the lateral direction and thereby being able to engage with the speed reducer 30 is fixed to the extraction guide 2.

The opening or closing phase of the drawer is the same as described above.
Specifically, in the opening stage, the stopper 17 is separated from the head 16 of the ratchet 4 under pressure with respect to the position shown in FIG. 8, and similarly, as shown in FIG. Separated from decelerator 30.

At this stage, the speed reducer 30 can be of any operating type, from which the pusher 32 protrudes.
10 and 11 show the reloading stage of the ratchet 4 by the electric motor 3 when the ratchet 4 and the spindle 14 return to the initial position.

  During closing of the drawer, as shown in FIG. 12, when the integral pin 22 of the withdrawal guide 2 is mounted using the self-closing system mounting element 21 and the spring 20 begins to drag the drawer toward the closed position, deceleration is achieved. Reducer 30 with second stop 31 hit and engaged until pusher 32 is retracted and the system returns to the position shown in FIG. 7 where stop 17 hits head 16 of ratchet 4 and rests. The deceleration is carried out by.

The third solution (FIGS. 13-17) operates according to the same principle for a door that swings against furniture or for the front panel of a drawer.
In FIG. 13, the dynamic part is, for example, a furniture door 82, while the static part is a side panel of the furniture 85.

Specifically, in this case, the device 1 represents a storage body 43 in which a ratchet 4 and an electric motor 3 coaxial therewith are arranged.
The ratchet 4 and the electric motor 3 are separated from each other by a divided partition wall 46 defined in the storage body 43 and are directed in opposite directions.

The two sliding portions 56 and 57 parallel to the common axis L of the ratchet 4 and the spindle of the electric motor 3 are slidable.
The sliding part 56 has a bent end 58 that engages with the head of the ratchet 4, while the sliding part 57 has a bent end 59 that engages with the head of the electric motor 3.

The other ends of the two sliding portions 56, 57 are bowl-shaped 60, 61, and the reason will be described in more detail below.
Preferably, the two sliding portions 56, 57 are flat and coplanar and are slidably included within the applicable lower or base guide 55 of the enclosure 46.

In the opening stage, as shown in FIG. 14, the head of the ratchet 4 applies pressure to release the ratchet 4 and thus open the door by thrust.
Actuation of the ratchet 4 causes the head of the ratchet 4 to move, causing an initial partial opening of the door. At this stage, the sliding part 56 protrudes from the guide 55 in which it is housed, and the hooked end 60 engages the hooked end 61 to actuate the electric motor 3 so that the electric motor 3 operates. 3 (FIG. 15).

  The operation of the electric motor 3 causes the head to protrude, thereby moving the sliding portions 56 and 57, and further moving the head of the ratchet 4 inside the housing 43 (FIG. 16) to a position where the ratchet 4 is blocked. Let

  Next, the head of the electric motor 3 moves backward while dragging the sliding portion 57, and the head of the ratchet 4 reaches the end point of the moving distance, and when the ratchet 4 is loaded again, FIG. As shown in FIG. 2, the slider 56 returns to the initial position while dragging.

At this point, the system is once again activated and the door can be closed without difficulty using any commonly available separate or integral self-closing device on the hinge.
A control device according to a fourth preferred embodiment of the present invention is shown in FIGS. 18, 19 and 20 (a) to f) of FIG.

  Again, the ratchet 4 is connected to the fixed guide 15 and further the self-closing device 29 is arranged on the fixed guide 15, but they can also be arranged on the fixed guide and the withdrawal guide in different ways.

  As can be seen in the first and second preferred embodiments of the present invention, the self-closing device 29 shows a housing 23 attached to the fixed guide 15 and can be dragged by an integral pin 22 of the withdrawal guide 2. Is slidable inside.

The electric motor 3 is arranged in the storage body 23, while the ratchet 4 is outside the storage body 23.
The housing 23 is provided with a guide 71, which is further straightened by a straight slot 72 that extends parallel to the axis L, by a first curved slot 73 on the extension of the straight slot 72. Formed by a cavity or second slot 74 starting from the midpoint of the general slot 72.

The attachment element 21 comprises a first pin 75 and a second pin 76 which are spaced apart in the direction of the axis L, and are attached to the guide 71 by these.
The attachment element 21 includes a flap 78, one end of the spring 20 is connected to the flap 78, and the other end of the spring 20 is connected to the storage body 23.

The spring 20 is arranged transversely with respect to the housing 23 and makes it easier to pivot the mounting element 21.
In the present embodiment, the electric motor 3 is movable in the axial direction by its action, as opposed to the safety spring 77 inserted between the electric motor 3 and the bottom of the storage body 23.

The stopper 17 is integrally disposed on the extraction guide 2.
In the opening stage of the dynamic parts of furniture, for example drawers or doors, passing from the position shown in FIG. 20 a to the position shown in b), b) allows the head to be released and protruded In addition, the ratchet 4 is pressed slightly by the stop 17 so as to allow the opening of the dynamic parts of the furniture.

At this stage, the pin 22 and the spring 20 retract and pivot the mounting element 21 from which the pin 22 is released.
Specifically, pin 76 reaches the end of the travel distance of linear slot 72 and pin 75 connects to slot 74.

  At the same time, the signal of the sensor causes actuation and retraction of the spindle of the electric motor 3, while the pressure causes a slight retraction of the electric motor 3 as opposed to the safety spring 77. In effect, the spring 77 acts to ensure the safety of the operation of the control device irrespective of when the external pressure is applied to the ratchet 4 (FIG. 20b)). In practice, at this stage, the spindle of the electric motor 3 can be retracted at a predetermined speed and simultaneously press the spring 77, so that the mounting element 21 still releases the pin 22 even if the external pressure is removed too quickly. Make sure. When the external pressure is removed and before the motor loads the spring 20 of the self-closing system, the position of the control device is always shown in any case, since the safety spring 77 must be sufficiently rigid. 20 b).

  The pressing of the spring 77 and the movement of the pin 22 eliminates the first motor block signal associated with the position of the pin 22 corresponding to the closed position of the drawer (position a) and the spindle retracts to the end of the travel distance. Make it possible to do. Here, the second motor block signal is neutralized by the presence of the mounting element 21 and thus makes it possible to reverse the movement of the spindle of the motor 3.

  Then, as can be seen from the position c), the withdrawal guide 2 can move freely as a result of the thrust received by the stop 17 from the ratchet 4 and a complete opening can be performed by the user.

  The pin 22 has been released from the self-closing system, and the motor 3 moves the spring 20 to its engaged position with the housing 23 in which the pin 75 is engaged in the slot 73 to push the mounting element 22. Operated opposite to the action. When this position is reached, the spindle of the motor 3 automatically returns to the end point of the movement position shown in d) and stays there by the second block signal.

  In the closing phase, after the spindle of the electric motor 3 has returned to the rest position and immediately after the pin 22 has re-engaged with the mounting element 21, the stop 17 contacts the ratchet 4 and the mounting element 21 is released from the housing 23. Therefore, the pin 22 is dragged in the closing direction as a result of the spring 20 returning (position d)).

  In this solution, the force of the spring 20 of the self-closing system is that of the ratchet 4 so that the latter force can be overcome to allow it to be re-loaded during the closing phase of the furniture dynamic part. Note that it is greater than the spring force.

  In the position shown in e), the spring 20 brings the mounting element 21 into contact with the spindle of the motor 3, while the stop 17 presses the ratchet 4, thereby allowing its mounting in the load position. The presence of the mounting element 21 neutralizes the second motor block signal so that the spindle is blocked by the block due to the presence of the pin 22 in a position corresponding to the closed position of the same drawer as position a). Moved to the position shown in f).

  The control device thus considered is capable of numerous modifications and variations, all of which are included within the scope of the inventive concept, and that all details are other technically equivalent. Can be replaced by details.

  In practice, the materials and dimensions used may be arbitrary depending on the requirements and conditions of the art.
