Description

Ejector for a movable part of furniture.

Field of the Invention

The present invention relates to an ejector for a movable part of furniture, in particular door or drawer, with a shock device and an electric drive unit, by which the shock device can be operated.

Background

According to the current state of the art, the electrically operated ejector devices must be triggered by the user using a switch provided specifically for it. For example, in the US document 6,338,536 an ejector device for a door of refrigerator, in which a male is applied to the door of the refrigerator drives it out after the maneuver of a firing device arranged on the door. Result inconvenient in this case, that for the device maneuver It is necessary to act intentionally on the ejector switch.

Summary of the invention

It is a problem of the invention to obtain a device of the cited generic type, which offers a greater comfort of use.

This is achieved according to the invention so that the drive unit can be triggered by action of traction and / or compression on the shock device.

If an ejector according to the invention is arranged in a piece of furniture, the action of traction and / or manual compression is enough on any point of the movable part of furniture to be ejected by the  user to fire the ejector. That is, the unit of ejector drive can be triggered by action of compression on the movable part of furniture in the closing direction thereof or by pulling action in the direction of opening of the movable part of furniture.

Preferably, the shock device is mobile limited, preferably in translation, between a First and second final position. This represents a very easy possibility of force acting through the ejector on the movable part of furniture. Anyway, in principle the shock device could be performed mobile also in rotation, for example in the form of an eccentric.

In another advantageous embodiment of the invention is provided that the shock device comprises a head arranged in a bushing, which is partially mobile coming out of the bushing, so that the bushing exerts a guiding function for the head that performs the shock Properly said.

For the realization of the planned functionality according to the invention it can be provided for example that the bushing is tightly closed at one end and that a switch, preferably a pressure switch, is disposed between the Hermetically sealed end of the bushing and head. How according to the invention the movable part of furniture in its final position closed is applied to the ejector, a compressive force exerted on the movable part of furniture can be transmitted to the head and maneuver the switch arranged between the closed end Hermetically sealed cap and head.

Additionally or alternatively you could register also a traction action on the movable part of furniture and shoot the shock device in reaction to it: By For example, the head could be magnetized at its free end, or a magnet could be arranged at said free end. Too a magnet is arranged on the movable part of furniture, namely  that the magnet or the magnetized area located in the head and the magnet located on the mobile part of furniture attract. If the part furniture movable moves out of its closed end position by tensile action, by force action between the magnets a head drag takes place, at least along a small stretch The shock device is triggered based on this drag.

In another advantageous embodiment of the invention it can be provided that sensors are arranged between the first and second final position of the shock device or in the final positions, and that the sensor signals can be feed at least the drive unit. Through these sensors can start other switching processes after the ejector shot. The sensors can be for example sensors optics, which are arranged along the longitudinal axis of the cap and that consist in each case of generating elements of light, for example light-emitting diodes (LEDs) and detection elements of light, arranged diametrically in front of each other. For example, by a pair of sensors arranged at a certain distance from each other along the longitudinal axis of the bushing, of which the first sensor records the presence of the shock device in its first end position and the second sensor records the presence of the shock device in its second final position, you can perform the following functionality:

After the deviation of the device head from shock that is in its first final position entering the socket, by means of the switch arranged in the socket carries out an activation of the drive unit, which move the shock device in translation to its second position final, so that the movable part of furniture that is applied to the Shock device moves out of its closed end position. As soon as the second sensor registers that the shock device has reached its second final position, it causes the disconnection of the drive unit. After a space of predetermined or predetermined time, for example 1 to 2 seconds, the drive unit is activated again to push the shock device back to the first position final. As soon as the shock device has reached its first final position, this is recorded by the sensor arranged there and The drive unit is disconnected.

Naturally, it can also be expected that the drive unit, after completion of the process ejection, can be fired through the shock device which is in its second final position, through a deviation of the head entering the bushing. Therefore, the immediate recoil of the shock device to the first final position can be triggered by the user, without having to wait for a predetermined period of time elapses. This can be constructively perform for example by means of the switch pressure arranged between the tightly closed end of the Bushing and head of the shock device. Deactivation of the drive unit after reaching the first position end of the shock device can be caused by the sensor arranged there.

In another advantageous embodiment of the invention is provided that the head has two arranged parts one inside the other in telescopic form, being preferably cushioned the movement of the parts relatively to each other. It is therefore possible to perform a damping of the mobile part of furniture during its closing movement, without having to foresee any additional component The damping function of parts arranged one inside the other in telescopic form can be perform in a manner known to the person skilled in the art, by example so that the head is made as an accumulator of pressurized fluid, or that a part is arranged loaded by Spring on the other side.

By arrangement of another sensor, arranged on the longitudinal axis of the bushing at a certain distance from the two sensors already described, another functionality of the  ejector according to the invention:

Once the ejector has been shot from the way already described and has reached its second final position, which has been registered by the sensor located there and announced to the drive unit, the telescopic removal movement of the inside of the head can be registered by means of a sensor properly disposed, so that the unit of drive is activated to move the shock device to its First final position.

During the expulsion process, the movement of removal of the inner part driven by force of the head outside the outside is prevented by the mass of the part mobile furniture accelerated by the head, which is applied to the part inside of the head. As for the movable part of furniture, after the completion of the ejection movement, lifts from the head or well it is lifted from it by the user, no longer opposes force any antagonist to the impulse by force of the parts of the head together, so that the inside of the head is can be deployed telescopically outside the outside of the head. This lifting of the movable part of furniture regarding the head can be registered as described, and as reaction to it can be triggered and the process of withdrawal of the shock device Once the shock device has backed into its first final position, kinetic energy residual of the movable part of furniture that is in the process of closure can be dissipated by the inside, still deployed, of the head.

The electric drive unit can comprise for example an electric motor or also a solenoid. Preferably, all components of the ejector according to the invention are arranged in a common envelope, so that the Ejector according to the invention is presented as an autonomous unit. The power supply of the ejector can be done by electrical contact with an external power supply appropriate. Now, to realize the constructive unity also autonomous, it can also be provided in the ejector a current accumulator, preferably a battery, by means of which the drive unit.

In case of realization of the sensors as optical sensors, of course it is not necessary for each sensor to be equipped with its own light source. It can also be planned, for example, dispose of the ejector as a whole only one light source, for example an LED, and drive the light from it by luminous conductors to the individual sensors.

In another advantageous embodiment of the invention provides for the provision of another sensor in the bushing, which in the first final position of the shock device registers the position of the inside of the two parts of the head arranged  one inside the other telescopically. Therefore, you can record the movement into the shot head by the movable part of furniture during the closing process of the part mobile furniture and place the ejector device back on set in its basic functional position. This takes place preferably with a certain delay, for example of 0.5 seconds, to prevent the ejector, in case of final speed too much large part of the movable part of furniture during the closing process, be fired again by maneuvering the switch provided In the cap.

Detailed description of the invention

Fig. 1 shows a piece of furniture 9 with a moving part 2 of furniture made as a door, being able to appreciate the ejector 1 arranged in the upper area of the body 16 of the furniture in this embodiment example.

Fig. 2 shows another embodiment, in the which the ejector 1 according to the invention is also arranged in a furniture 9 with a movable part 2 of furniture made as a door, in the upper side of the body 16 of the furniture. The shot of shock device 3 takes place in this embodiment by means of a switch or proximity sensor 18 disposed in the furniture body, whose signals can be fed by a conduction 19 to the ejector. The proximity sensor 18 reacts to a tension or compression action caused manually on the door closed and activates the ejector 1.

Both in the embodiment shown in Fig. 1 as in Fig. 2, the functionality of the ejector trip provided according to the invention is effectively obtained by user force action on any point of the door in its closed position. To do this, it is necessary to provide naturally, in case  compression action, even in the closed final position of the movable part 2 of furniture, namely in this case the door, certain clearance for the movement of the movable part 2 of furniture in the address of the ejector 1, namely in the closing direction, caused by the compression action by the user.

If the movable part of furniture is a drawer, the ejector according to the invention could act for example from behind on the back side of the drawer or on an overhanging part of the drawer faceplate.

With the help of Figs. 3 to 6, the application of an exemplary embodiment of the ejector according to the invention.

Fig. 3 shows a sectional representation of a exemplary embodiment of an ejector 1 according to the invention, it can be seen that the shock device 3 is composed in this exemplary embodiment by a socket 5, in which it is limitedly arranged a component, which has two Parts 6 and 7 arranged inside each other telescopically. I know  you can also see switch 15, configured in this exemplary embodiment as a pressure switch, at the end closed of the bushing 5. Along the longitudinal axis of the bushing sensors 10, 11, 12 and 13 are arranged to certain mutual distance, each sensor consisting of two components. In this example of embodiment, the emission of light is effected by means of components arranged on the left in Fig. 3 of the sensors 10 to 13, while this light is detected by the components arranged to the right of the sensors 10 to 13. For this they are naturally provided areas that let light through, for example slits, both in the bushing 5 and in parts 6 and 7. sensors 10 to 13 are connected by means of conduits not represented with the electric drive unit 4 realized in this exemplary embodiment as an electric motor, which by a gear 14 moves the bushing 5 and therefore the parts 6, 7 and 15 arranged in it. The power supply of the unit drive 4 takes place via the current accumulator 8 (here: battery) schematically represented, so the Ejector 1 represents an autonomous and autonomous component. The extraction movement of the inner part 6 driven by force outside the outer part 7 is prevented by the part furniture mobile 2 which in its final closed position is applied to the shock device 3. In Fig. 3, the ejector 1 is in Your basic position ready for shooting.

By a compression action 20 represented schematically by a user on the furniture door in his closed position, parts 6 and 7 are compressed against the switch 15 in socket 5, so that it triggers, by  a conduction not shown, the drive unit electric 4, which by means of gear 14 causes the expulsion process by translational movement in translation of bushing 5 and parts 6 and 7 arranged therein to the second final position of the shock device 3 represented in Fig. 4. The sensor 11 detects when the second final position by the shock device 3, and it stops drive unit 4. Fig. 4 shows the situation shortly before the movable part 2 of furniture, namely in this example of realization the furniture door, has risen from the shock device 3 or be lifted from it. May it is appreciated that in this situation the movement of extraction of the part 6 arranged telescopically on the outside 7 is still prevents by the part 2 of furniture that is applied.

Fig. 5 now shows the situation after the movable part 2 of furniture has moved away from the shock device 3. Therefore, the force-driven inner part 6 can be move out of the outer part 7 in a telescopic way, so that it can later cause a damping function, that is a dissipation of the residual kinetic energy of the part mobile furniture 2 in close proximity to its closed end position. East removal movement of the inner part 6 outside the part exterior 7 is registered by sensor 10 and announced by means of a conduction not represented to the unit of drive 4, so that this causes a movement of recoil of the shock device 3 to its first final position. As soon as this first final position has been reached, through the sensor 13 disconnection of the drive unit takes place 4. When the mobile part 2 of furniture is now carried by a user not represented, again to its closed final position, namely close the door, the backward compression of the inner part 6 on the outer part 7, which is recorded via sensor 12. The system as a whole is again in the basic position, which is announced to the unit of 4 drive after a delay of approximately 0.5 seconds.

The following explains, with the help of Fig. 6, an alternative maneuver development, which is connected in time to Fig. 4 and replacing Fig. 5. To do this, the mobile part 2 of furniture is compressed again, immediately, without opening more manually, in the direction of its final closed position. This it can take place for example if the user, after firing the ejector 1, does not want a complete opening of the furniture 1. Therefore, the inner part 6 cannot move outside the outer part 7, because the movable part 2 of furniture permanently exerts a force antagonist on the inside 6. Through the action of compression 20 taking place now, schematically represented, by the user, the bushing 5 as a whole is compressed in the address of your first final position, which is registered by the sensor 11 and announced to drive unit 4. This causes then the continuation of movement into the device of shock 3 to its first final position, bringing the ejector 1 He is taken back to his basic position.

Fig. 7a and 7b schematically show the firing of the ejection process by pulling action on the movable part of furniture.

Fig. 7a shows the movable part 2 of furniture in its end position closed. At the free end of head 17 is arranged a magnet 21. Also, at the corresponding point in the movable part 2 of furniture is arranged a magnet 22, so that both magnets 21 and 22 exert a force of mutual attraction.

Fig. 7b shows the movable part 2 of furniture a once it has been moved by traction action, by a user not represented, something outside its final closed position. Through the force of attraction between the magnets 21 and 22, the head 17 is has partially moved out of the bush 5. It is therefore fired drive unit 4 and the ejection process begins.
