DE102005020027A1 - Electrical drive device for rotary clothes dryer, comprises wind-on device for lifting cable on rotary clothes dryer, drive lifting cable connected with the lifting cable by fixation eyelet and/or cable, and motor driving the wind-on device - Google Patents

Abstract

The lifting cable (3) of the rotary clothes dryer is mechanically coupled to the wind-on device (27) of the electrical drive device (5). The drive device further comprises a transmission formed in a direction of rotation self-locking, a blocking device containing controllable magnet device, a battery and/or a rechargeable battery and/or an electric connection, a limit switching off device readjustable by a turning mechanism, a solar collector and/or a windmill, and a fixing element containing a sheath for fixing the drive device to the clothes dryer. The switching off device switches as a function of the capacity of the engine and/or the transmission torque. In the drive device, a resting prevention device for deactivating resting mechanics of the clothes dryer and a spring device for causing a springs mechanical coupling of the lifting cable are used. The spring device is a component of the motor and/or the transmission and/or the wind-on device and/or the drive lifting cable (23). The drive device is operated by a radio-remote control and/or an optically operating remote control. The fixing element exhibits a thorn insertable into the mast of the dryer, and the drive device is fastenable at the mast-heel and the slide joint (13) of the dryer. An independent claim is included for a rotary clothes dryer.

Description

The The invention relates to a support frame, preferably for laundry or Garden umbrellas, with an upright mast, on which in a sliding joint the Clothes line or the umbrella cap carrying arms pivotally mounted are, which have spreader arms supported are, on the one hand by means of holding axes in a holding star on the mast and on the other hand pivotable by means of articulation axes on the arms are stored, and an elevator line.

such Carrying racks are in use millions of times. To open this Carrying frames becomes very common a lift cord used, which is attached to the slip joint and a Deflection led in the holding star is. This pulley-type guide the elevator leash did facilitate the clamping of the supporting frames, it still has to A relatively high initial force is expended on the arms to transfer their rest position in the initial spreading position. Of course the forces all the more bigger, ever bigger this Support frames are formed. This resulted in a power requirement which is difficult to raise by the average operator.

In order to facilitate the process of opening and closing or automate, it is through the DE 100 02 111 A1 known to provide a mast driven by an electric motor lifting device, wherein the lifting device has a spindle arranged substantially parallel to the mast, on which a lifting nut is guided against rotation, wherein the arms of the umbrella-like frame are pivotally supported on the lifting nut.

With This lifting device is natural a comfortable opening and closing the support frame possible. This can even be over a remote control. A disadvantage is the high construction costs, the one for the Support frame of a normal household laundry screen not acceptable is. Another disadvantage is the fact that the mast be executed slotted must, so that to Compensate for this weakening corresponding reinforcements are required at this.

task The invention is a support frame of the type mentioned whose umbrella-like frame can be easily opened and closed, where The construction cost is to keep so low that this support frame for mass products like little household laundry umbrellas and umbrellas is usable.

These Task is solved by that the elevator cord executed as an endless loop, with the sliding joint frictionally connected and over one Deflection and a drive out is. The drive can be used both as a manual drive and as an electric drive accomplished be. Naturally is in the drive depending on the size of the support frame integrated a gearbox for power reduction.

Around when using an electric drive this independent of a power supply to make, this is connected to a power storage. As power storage lend themselves to rechargeable batteries. Especially advantageous is it when this battery is over a solar module is powered. This solar module is expediently arranged at the end of the mast and can thereby simultaneously as a cover and rain cover for the clotheslines or the ski cap be formed.

Around To further reduce the number of components is the diversion expediently integrated in the holding star at the end of the mast.

The Arrangement of the drive below the low point of the sliding joint on the mast allows Such a drive also later in a support frame integrate, where appropriate the endless loop outside the mast is arranged. But even with space-saving protected arrangement the endless loop through the mast interior are just simple breakthroughs for the loop, which may be designed both as a leash, as well as a band, required.

Two embodiments The invention will be explained in more detail below with reference to the drawings. It demonstrate:

1 A support frame simplified half-side with drive in the open state shown and

2 an alternative solution when closed.

On a mast 1 is a slip joint 2 concerning a holding star 3 slidably mounted. On the slip joint 2 are four arms 4 over swivel axes 5 pivoted. Between the poor 4 is a clothesline 15 curious; excited. The poor 4 are via spreader arms 6 against the holding star 3 supported. The spreading arms 6 are by means of steering axles 7 on the support arms 4 and by means of holding axes 8th at the stops 3 stored. By moving the sliding joint 2 upwards are the arms 4 like on the left half of the 1 visible, spread and the scrubbing screen is clamped. This is done via a lift line 9 ,

The elevator rope 9 is as an endless loop 11 executed, with the housing 12 of the sliding joint 2 positively connected and via a deflection 10 in the area of the Haltestern 3 and a drive 13 guided. The drive 13 , it can be provided depending on the size of the support frame with a reduction gear, is by a hand crank 14 actuated.

In the illustrated embodiment, the endless loop runs 11 in the force area outside and in the retreat area within the mast 1 , Of course, the redirection 10 also in the holding star 3 be integrated.

The clothesline is with 15 designated.

In 2 an alternative embodiment is shown at rest. The drive 13 is there with an electric motor 16 coupled by a battery 17 is fed. This battery 17 is from a solar panel 18 at the end of the mast 19 is mounted, fed.
