DESCRIPTION

Drive unit for a sliding sliding blade

The invention relates to a drive unit for sliding sliding blade, which can be attached to a sliding blade and having a drive motor and a gear connected to which the output member is solidly connected with at least one running wheel, where the treadmill can be inserted on a fixed raceway.

The drive unit of the type described above is designed and is especially suitable for the sliding leaf of sliding door cabinets, but nevertheless it can also be used for sliding windows or sliding doors.

An already known drive unit is equipped with an electric motor not described in more detail. On the free end of the drive shaft there is mounted a symphony integral to the rotation that meshes with the outer teeth of a disc. This disc is provided with a drive groove that is provided with an internal teeth that meshes with the external teeth of an axis. This axle houses a treadmill, where the axle serves as a rolling surface. This drive unit is secured in a housing-type supplement that is inserted into a recess designed correspondingly from the sliding blade. The running wheel is formed by wheels located in pairs that roll on the tread surface of a raceway.

In that drive unit it is especially disadvantageous that the electric motor is attached to the sliding leaf on the outside and that the gear unit is of relatively large dimensions. This is especially valid for the electric motor that is separated from the gear by a relatively long shaft.

Document DE 10 2007 030 081 publishes an automatic sliding leaf installation in which a drive and an energy supply device by means of which the drive can be operated are provided on a sliding sheet. The power supply device comprises an accumulator located fixed on the sheet that can be connected to a fixed network.

The invention is based on the mission of designing a drive unit of the type described in more detail at the beginning, in a more simple constructive way as a compact unit, so that this drive unit can be installed as a fairly invisible minimum on a sliding sheet , for example, of cabinets with sliding door.

The proposed mission will be resolved for the purpose of claim 1.

Then the drive motor of the drive unit is a direct current motor of inner rotor or outer rotor or disc rotor, with brushes or brushless, provided with output munon, and / or the power supply to the motor The drive is produced by an energy source installed in the sliding leaf.

DC motors with an internal rotor or external rotor in a flat construction or disc rotor motors, provided with brushes, preferably with a collector, or brushless, preferably electronically commutated, can be obtained in extraordinarily compact construction types. They can also be coupled with the gear in a way that saves a lot of space. Preferably these motors are designed as motors driven by permanent magnets with a coreless rotor and drum manifold. They have a low inertia hydrodynamic gait behavior. They can be easily adjusted within the speed range and even at the lowest speeds the gear is maintained exactly. The winding is usually designed as a coil of wire. Up to now, disk rotor motors have been used for dynamic regulations and numerous electrical devices, for example, for movement systems of devices for entertainment electronics.

Especially advantageously, the drive motor is electronically switched for regulation purposes.

By using sliding blades of the type described in detail above, the drive unit equipped therewith can be installed on the sliding blade as a fairly invisible minimum, as a consequence without disturbing.

As also the voltage source and the drive motor as well as if necessary a control unit can be installed on a sliding sheet, these can also be installed covered. The conductive union of

The electricity between the drive motor, the voltage source and the control unit is carried out in a known manner, by means of conductive wires or cables.

In another design it may also be provided that a constructive module is formed with the voltage source and the control unit. In this way the construction module can be installed on the sliding sheet already preassembled. However, it is also possible that the drive motor, the voltage source and the control unit are constructed as a construction module. The voltage source is a DC voltage source (DC voltage source) in the form of a battery or a battery. This also achieves the necessary safety since it is a low safety voltage, for example, 12V or 24V.

In order for the drive unit to work without sliding, it is provided that the joint according to the drive technique between the output motor of the drive motor and the running wheel is formed by a chain of cogwheels that engage with each other. Therefore, in an advantageous development, the wheels of this chain are designed so that the speed of rotation of the output munon of the drive motor is reduced.

It is envisaged that the chain of wheels has a pinion seated in solidarity with the rotation on the output world of the drive motor, which meshes with an intermediate pin that rests being able to turn freely on a fixed pin, pinon that meshes with a crown of teeth interiors that rotates the running wheel. Therefore, it can be provided that the number of teeth of the pinon seated on the output world of the drive motor is greater than the number of teeth of the intermediate pinon.

The intermediate pinion meshes with a crown of inner teeth that is seated or shaped on the inner surface of the treadmill. For the reason of a simpler support for the running wheel, it can also be provided that the crown of inner teeth is provided in a coupling disc that is connected to the running wheel by form closure and / or force closure. In this last mentioned embodiment, it is provided that the coupling disc has drive tabs that project axially and are angularly offset with each other, that engage in recesses that extend in the longitudinal direction and are adjacent to the bore of the running wheel.

It is also provided that the axes of rotation of the pinon seated in the output world of the drive motor and of the intermediate pinon are of parallel axis with one another, although displaced with respect to the axis of rotation of the running wheel. This can be achieved constructively, because, for example, if the drive motor's output munon rests on a support sleeve that is formed or seated on a bearing shield that can be attached to the sliding blade, and this output munon It has an eccentrically located support hole on which the drive motor output is supported. To this end, a centrally located housing projection is supported by a bore of a bearing sleeve of a bearing shield, the bore being eccentrically located.

In order that the moment of rotation necessary for the sliding blade to move, which has to be applied by the drive motor, is as small as possible due to the easy rotation of the running wheels, it may be provided that in the Drill of the rolling wheels a bearing is inserted whose inner ring is inserted integral with the rotation in the bearing sleeve of the bearing shield.

The wrapping surface of the tread wheels can be constructed in the form of steps where the area surrounding the pinon with the largest diameter forms the tread surface. In the adjacent area the bearing is inserted. So that the entire drive unit can be firmly attached to the sliding blade, it can be provided that the area of the rolling wheels that limit the tread surface is inserted into a drill hole. a support support, which can be attached to the sliding leaf. This support support could be called main support.

In addition, it could also be provided that the part of the running wheels that can be introduced in the fixed rail, and that contains the rolling surface is laterally next to the sliding blade and that the remaining part of the drive unit can be introduced in the emptying of the sliding leaf.

So that the power supply of the drive motor is always secured, it can be provided that the voltage source is constructed as a rechargeable accumulator and that the accumulator, in the closed position of the sliding leaf, is connected by an electric conductor, with a fixed charging device. In this embodiment, the loading apparatus is placed in a fixed module adjacent to the edge of the sliding sheet. The electrically conductive union could be formed, for example, by plug-in contacts.

Another possibility is the wireless supply of the accumulator by inductive transmission of the fixed part of a charging device on the mobile part of a charging device.

In addition, it can be thought that there is a transmission of wireless ene from the furniture body to a movable part of furniture for the entire length of the movement, so that on the sides of for example the sliding sheet no longer necessary energy accumulator

Alternatively, it is provided that the voltage source is conceived as a rechargeable accumulator and that the rechargeable accumulator and a charging device are located on the sliding sheet and connected with it, and that in the closed position of the sliding sheet the Charge is connected with electric conduction to a mains voltage source.

The invention will now be described in more detail on the basis of a constructive example and with reference to the drawing. It shows:

Figure 1, a drive unit according to the invention, in an exploded representation, Figure 2, the drive unit according to Figure 1 in assembled state, in a sectional representation, in conjunction with a partially shown sliding sheet,

Figure 3, the drive unit according to Figures 1 and 2 in assembled condition, with a view on the treadmill,

Figure 4, a corresponding representation with Figure 3 but with a view on the drive motor, Figure 5, a corresponding representation with Figure 3 but with a joint view of a sliding sheet shown partially sectioned,

Figure 6, the drive unit attached to a sliding blade with a view on the drive motor, and Figure 7, a representation corresponding to Figure 6, however, with a view of the running wheel.

The constructive example of a drive unit 10 shown in Figures 1 to 5 shows a drive motor 11, a bearing shield 12, a support support 13, a race wheel 14, a bearing 15, a pin 16, a pinon intermediate 17 and a coupling disc 18.

On the housing projection 20 of the drive motor 11, a bearing shield 12 sits in solidarity with the rotation and is attached to the drive motor 11 by means of three screws not shown. On the opposite side of the drive motor 11 the bearing shield 12 is provided with an integral support sleeve 21 eccentrically located to the flange of the support sleeve 21 and which in turn is provided with an eccentric bore 22 diametrically opposed to the eccentricity of the support sleeve 21, to provide sufficient wall thickness next to the hole 22 in the envelope of the support sleeve 21 to accommodate a bolt 26.

The flange 23 of the support support has a quadrangular construction and in the corner areas it is provided with a hole in each of them. The peripheral surface of the running wheel 14 is constructed in the form of steps, where the tread surface 24 has the largest diameter and laterally is next to the flange 23. The adjacent area in the direction of the drive motor 11 has a design like support sleeve 25 to accommodate bearing 15.

Pinon 16 forms the drive pin and is seated integral to the rotation on the output munon 19 of the drive motor 11. This pin 16 engages with an intermediate pin 17 which rests, being able to rotate freely, on a pin 26 with extension from the front. The coupling disc 18 is provided with an internal toothing 27 with which the intermediate pin 17 engages. In the part oriented towards the flange 23 of the support support 13 the intermediate disk 28 is provided with several drag tongues 28 extending in the direction axial and form an angle between each of them, and which fit into the corresponding recesses of the non-toothed running wheel 14, which are located on the front face on the face opposite to the drive motor. As shown in Figures 1, 2, 3 and 4, the flange 23 of the support support 13 is provided in each of the corner areas with a hole for receiving the fastening screws 38 for the sliding blade (see Figure 5).

Figure 2 shows in conjunction with Figure 4, that the drive unit 10 can be inserted into a circular opening 29 of a sliding leaf until it abuts the rear part of the flange 23.

Figures 6 and 7 show that the sliding sheet 32 can be guided on a rail rail 31 by means of a stop piece 35, which is guided on the sliding sheet 30, where both tread marks are horizontally parallel totally together with each other. . These executions presuppose that the sliding blades cannot run completely superimposed, because if not, a user does not have any access to the handle element in the sliding blade 30. In an arrangement like this, the drive unit 10 may be or located seated on the sliding blade 32 or be equipped with an extension of the outlet world or other measures to achieve the mounting depth (to the rear of the flange 23). Naturally, the drive unit 10 is located on the sliding sheet 32 only on the part that does not move superimposed with the sliding sheet 30 (not shown).

Figure 2 shows that in the sliding sheet 30 which presents the drive unit 10, a storage tank 36 is placed. In a suitable position for this storage unit a charging apparatus 37 is installed in an adjacent module. This charging device can be connected to a mains voltage source by means of a conductor. The electric conductor connection between the accumulator 36 and the charging apparatus 37 is produced in the closed state of the sliding sheet by means of contact bolts and contact bushings.

As figures 1 and 2 especially show, pin 16 16 is seated on the outlet munon 19 of the drive motor 11 and the housing shoulder 20 is inserted into the bore 22 of the support sleeve 21, whereby the displacement is achieved between pin 16 and intermediate pin 17 with respect to the axis of rotation of the drive motor. The outlet munon 19 then protrudes from the front surface of the support sleeve 21 so that pinon 16 with the largest number of teeth sits in solidarity with the rotation on it. The intermediate pinion meshes with pinon 16 and the internal teeth 27 of the coupling disc 18. The bearing 15 is inserted into the support sleeve 25 which is supported by the rolling wheel 14. The drive tabs 28 engage in the grooves of the bore in the area of the tread surface 24 of the tread wheel 14.

The invention is not limited to the constructive example shown. It is essential that, for example, using a disc rotor motor 11, a compact drive unit is created which, with the exception of the tread wheel 14, is mounted in a hollow of a sliding leaf 30, for example, of cabinets with sliding doors . In addition, also the voltage source 36, for example an accumulator, and advantageously the control unit for controlling the disk rotor motor, can be mounted on the sliding blade.
