  • the DE 203 08 256 U1 discloses a furniture drive in the form of a linear drive integrated in the drawer guide.
  • the linear drive is designed as a bimetal spring drive.
  • a piezometer is mentioned as an alternative to the bimetal spring drive.
  • the object of the invention is to provide a guide device of the type mentioned at the outset, which is of compact construction and is equipped with a powerful electric drive.
  • the guide device is characterized in that the piezoelectric actuator system is designed in such a way that when excited, a bending shaft rotating in a circumferential direction of the stator is generated.
  • the electric drive is not located on a peripheral component, for example on the furniture body or on the furniture pull-out, but is part of the guide unit of the guide device. This makes it possible to accommodate the electric drive in a space-saving manner. This means that there is no need for an electric drive, particularly on the furniture body or on the furniture pull-out be installed, but the assembly takes place on the already existing guide unit.
  • the electric drive is part of a drive module that can be handled in a uniform manner and can be accommodated as a unit in the guide unit.
  • a drive module can be assembled and disassembled in a simple and quick manner, for example for maintenance or for replacing the electric drive.
  • the electric drive has a stator arranged on the carcass rail and a driven member that is relatively movable for this purpose, coupled to the pull-out rail or forming it.
  • Essential components of the electric drive in particular the stator and the output member, can therefore be arranged between the body rail and the pull-out rail. It is possible to integrate the electric drive into a guide unit designed as an automatic feeder with a carcass rail, a pull-out rail and a middle rail in between.
  • the electric drive can be arranged between the body rail and the middle rail or between the middle rail and the pull-out rail.
  • the electric drive is designed as an electric linear drive, in particular an electric linear direct drive, with an output element that is guided linearly along the stator.
  • a linear movement generated by means of the electric linear drive can be tapped via the output member and transferred directly into a linear movement of the pull-out rail without any transfer means.
  • the output member is also referred to as a rotor when an electric linear drive is used.
  • the electric drive for driving a further drive is coupled to the further drive via coupling means.
  • the electric drive can be designed as an auxiliary drive with which the main drive can be controlled, activated, charged or the like.
  • the auxiliary drive can be used, for example, with a lock, such as a child lock or interchangeable lock.
  • a spring for example, can be used as the coupling means, which can be tensioned by means of the electric drive and releases its stored spring energy when required. It is also possible for the electric drive to activate or actuate an actuating member known from the prior art and mentioned above, for example an ejector or ejector.
  • the electric drive is designed as a piezoelectric drive, with a piezoelectric actuator system for driving the output member.
  • the piezoelectric actuator system sits on the stator or forms the stator.
  • the piezoelectric actuator system is designed in such a way that when excited, a bending shaft rotating in a circumferential direction of the stator is generated. Electric drives with such a piezoelectric actuator system are also referred to as traveling wave motors.
  • FIG. 1 A preferred embodiment of the invention is shown in the drawing and is explained in more detail below.
  • the only figure in the drawing shows: a preferred embodiment of the guide device according to the invention in a schematic perspective view.
  • the figure shows a preferred embodiment of the guide device 11 according to the invention for guiding a furniture pull-out (not shown) which can be moved relative to a furniture body.
  • the guide device 11 is preferably used in a furniture pull-out designed as a drawer. It is of course possible to use the guide device 11 also with other pull-outs.
  • the guide device 11 is explained below using the example of a drawer.
  • the drawer is slidably mounted relative to the furniture body (not shown) by means of the guide device 11.
  • the guide device 11 comprises several guide units 12, of which two opposite side edges of the drawer are assigned.
  • the guide device 11 can be a so-called underfloor guide, in which the guide units 12 are assigned to the drawer bottom. Alternatively, it would be possible for the guide unit to be integrated into the side wall of the drawer.
  • the guide unit 12 has a body rail 13 which is to be fixed in place on the furniture body and a pull-out rail 14 which is relatively movable in relation to this and which is to be mounted on the drawer.
  • the pull-out rail 14 is mounted on the underside of the drawer bottom, while the body rail 13 is located on the bottom of the drawer compartment opposite the drawer bottom.
  • the body rail 13 is expediently mounted on the side wall of the drawer compartment, while the pull-out rail 14 can be integrated, for example, into the side frame of the drawer.
  • An electric drive 15 is also provided, which is integrated in the guide unit 12.
  • the electric drive 15 is part of a drive module 40 which can be handled uniformly and accommodated as a unit in the guide unit 12.
  • the guide unit 12 with the electric drive 15 is suitable both for partial pull-outs and for full pull-outs which, in addition to the carcass and pull-out rail, also have a further pull-out rail - also called a central rail.
  • an electric drive 15 with a relatively small structural size is required, which therefore takes up little space overall.
  • the figure shows a special form of the piezoelectric drive, namely a piezoelectric linear drive.
  • the piezoelectric linear drive is designed as a so-called linear traveling wave motor.
  • the principle of a traveling wave motor is based on the fact that in the stator 16 of the motor excites resonant vibrations, superimposes waves that are to be continued and transmits these oscillating movements to the drive by friction.
  • the traveling wave motor shown in the figure acts as a linear direct drive, the stator 16 being connected to the body rail 13.
  • the stator is designed as a ring stator, which consists of two straight sections, a drive section 17 and a bearing section 18, which are connected by two semicircular arcs.
  • a piezoelectric actuator system 19 with a plurality of piezoelectric actuators 20 is arranged on the inside of the bearing section 18. Platelet-like piezoceramics are used as piezoelectric actuators 20.
  • the ring stator can be suspended by two membranes (not shown) along both sides of the bearing section 18, so that the ring stator is fixed in space, but the traveling wave can circulate undisturbed in the waveguide.
  • A sits on the upper drive section 17
  • Output member 21 in the form of a runner, which in turn is connected to the pull-out rail 14.
  • the bearing section carries a tooth structure 22.
  • the rotor engages around the tooth structure 22 and is moved in one direction or another along the tooth structure 22 depending on the direction in which the traveling wave rotates.
  • the movement device not according to the invention which is not shown in the drawing, is assigned a furniture part which is movable relative to a furniture body in the form of a drawer, furniture flap, door or the like.
  • the movement device is explained below using the example of a drawer.
  • the movement device has adjusting means which can be coupled to the drawer.
  • An electrical drive in the form of a piezoelectric drive is also provided.
  • the movement device according to one exemplary embodiment comprises a device housing in which an actuating member in the form of an ejector or ejector is movably mounted.
  • the actuator can be pivoted between a retracted and an extended position. The user swings out after a trigger command, which moves the drawer out of the retracted position from the furniture compartment.
  • the electric drive in the form of the piezoelectric drive is used to actuate or pivot the actuating member.
  • a piezoelectric rotary drive in the form of a traveling wave motor with a rotating flexible shaft is provided, which is characterized by a particularly flat design.
  • the linear traveling wave motor described above could also be used.
  • the shaft motor has a flange plate that is attached to the device housing.
  • the flange plate carries an annular vibration stator on which there is at least one piezoelectric actuator.
  • the piezoelectric actuators are arranged in a ring, as a result of which the disk-shaped stator is excited to vibrate in such a way that a traveling wave is formed in the form of a rotating mechanical bending wave.
  • the disk-shaped stator rolls on a polymer contact layer, which is located on a rotor.
  • the rotor is pressed onto the stator by a plate spring, whereby a rotating movement of the rotor is generated when the traveling shaft rotates and can be tapped via a drive shaft.
  • the drive shaft is connected to the actuating member via coupling means in the form of a gear.
  • the transmission consists of a belt transmission section which is coupled to a gear transmission section, the latter being coupled to a bearing shaft of the actuating member, as a result of which a rotational movement can be converted into a pivoting movement of the actuating member.
  • the movement device described above is not limited to the embodiment of the ejector unit with ejector.
  • the movement device could also be part of an automatic feeder, a pull-out device or the like.
