Description

Drawer drive

Technical field

The present invention relates to a kind of drive unit that is used for drawer, it is that be provided with respect to motor and by the drivable support of motor, drivening piece is bearing on this support movably to comprise that a motor, one are used for that power is delivered to drivening piece on the drawer and one.

Background technology

A kind of such drive unit is for example from EP 1 374 732 A1.In the drive unit shown in the there, drivening piece and a support that constitutes odontoid belt are affixed.Though drive unit can be applied to power on this drawer whole the opening or closing on the path of drawer.Yet essential for this reason is, odontoid belt constitutes corresponding length.Especially in the prior art on the front end of furniture cabinet, must be provided with the directive wheel that is used for odontoid belt.This is a shortcoming with regard to this respect, and the user often requires to hide the drive unit of setting, and described drive unit keeps not driving the illusion of drawer.

For the motion with motor more advantageously is delivered on the drawer, in EP 1 374 732 A1, can be provided with a transmission device in the disclosed drive unit.Though therefore obtained the function of wishing.Yet use a transmission device that separates to bring additional expense.

By the preamble of claim 1 be used to have a motor, one and be used for power is delivered to drivening piece on the drawer and one drive unit by the drawer of the drivable support that is used for drivening piece of motor by following documents as can be known: WO 20037002838 A1, EP 1 508537 A1, US 3,298,765 and US 3,028,209.

Summary of the invention

The objective of the invention is, propose a kind of drive unit, this drive unit obtains function by existing techniques in realizing with less design and economic cost.

Described purpose solves by a kind of drive unit that is used for drawer, this drive unit comprises a motor, one is used for power is delivered to the support that drivening piece on the drawer and are that be provided with respect to motor movably and can drive by motor, drivening piece is bearing on this support, drivening piece is arranged on the support movably, wherein drivening piece and support coupling join, make the move through support of drivening piece on support force control with respect to the motion of motor, wherein, be provided with a traction piece, drivening piece is connected with this traction piece, and support can be provided with movably with respect to traction piece.

Characteristics of the present invention are, drivening piece-be different from prior art-be arranged on the support movably.Obtain other freedom of motion by described measure, it can be used for realizing passing through in the prior art the function that additional parts are realized with simple and cheap mode.Force control by support with respect to the motion of motor by the motion of drivening piece on support, guarantee between motor and drivening piece, to exist continual power path (Kraftstrang).

For example can cancel the additional in the prior art transmission device that is provided with in by drive unit of the present invention, this moment, drivening piece was by a transmission mechanism and support coupling connection.There is multiple possibility available in order to design the formation transmission mechanism.For example can stipulate, between support and drivening piece, be provided with the gear of different-diameter.

Yet a kind of embodiment is particularly preferred, and wherein drivening piece is connected with a preferred cable traction device of traction piece, and support can be provided with movably with respect to traction piece.Yet needn't be provided with a transmission mechanism in said embodiment.

For example can realize a kind of transmission mechanism in the following way in said embodiment, wherein traction piece is fixed with respect to motor at least one position along its length.Thereby by the motion of moving the drivening piece that by the fixing given border of traction piece in traction piece take place and with traction piece be connected of support with respect to traction piece.Therefore realize a reverse assembly pulley in principle, its medium-height trestle plays the effect of pulley.About drivening piece transmission by the motion of support experience takes place by driving arm.Causing gearratio under the situation that the support of single twines is 1: 2, that is to say that support motion 1cm causes traction piece (thereby and drivening piece that is connected with the traction piece) 2cm that moves.Can obtain higher gearratio by traction piece about the higher winding number of times of support.Higher gearratio applies driving force by corresponding bigger needs certainly and exchanges for.

In order to ensure the trouble-free winding of support, can stipulate that a traction piece part extends through preferred two guiders (preferred roller) that are arranged on the support.

Another advantage by drive unit of the present invention is its very compact structure mode.For example can stipulate that the every other parts of motor and preferred drive unit are arranged on the base plate.This causes assembling simply and apace drive unit, also is specially adapted to equip furniture by drive unit of the present invention thus afterwards.

Meaning by the cramped construction mode can be stipulated, a track is set on base plate, and support can move along this track.

Can stipulate that in all embodiments support constitutes slide (Laufwagen), because guarantee good especially activity at this point.When being provided with the guider that is arranged on the part that is used for traction piece on the support, in addition maybe advantageously, support has at least two rollers, and support rolls along track in orbit by described roller, and the part of wherein said traction piece extends through described at least two rollers.Therefore produce compact structure.

Traction piece itself can be realized in orbit with respect to fixing of motor.Can use a lot of different fixed positions according to embodiment for this reason.

The driving of support itself can realize with different types and mode.One embodiment of the present invention are particularly advantageous, wherein are provided with an other traction piece, and wherein other traction piece can be connected by the motor driving and with support.

Preferred motor constitutes motor.

In addition in order to ensure drive unit be easy to replenish equipment property, can stipulate that drivening piece has a releasable coupling that is connected of drawer that is used for the needs driving.For example drivening piece can have a fast moving switch (Schnapper), and the pin that can be installed on the drawer can be embedded in this fast moving switch.

The present invention relates to a kind of furniture that has the furniture cabinet and be bearing in the drawer in the furniture cabinet versatilely in addition, this furniture is characterised in that at least one drive unit according to above-mentioned any form of implementation is set.

When the regulation drive unit only is fixed on the furniture cabinet with its base plate, produce a kind of especially simply assembling.For example can preferably not having instrument ground realizes drive unit is contained on the section bar track that extends in the furniture cabinet.On the section bar track a plurality of drive units can be set at this, wherein each drive unit is attached troops to a unit in a drawer.

Because the flat structure of drive unit, described drive unit can be arranged on below the drawer that drives, even under the situation of a plurality of drive units that are used for different drawers of use, also keep enough spaces thus.

In order to reduce the observability of drive unit for the user, can stipulate that drive unit constitutes microscler, wherein the length of drive unit is preferably less than 2/3rds of the degree of depth of furniture cabinet.

The drawer that needs to drive preferably can be on the extraction guide rail of two-side supporting in the furniture cabinet, and described extraction guide rail is used to bear the load of drawer.Therefore drive unit only need overcome the inertia mass of drawer for this driving.
