Abstract

The invention relates to a lifting device, comprising a fastening device for fastening to a ceiling and/or a wall, an electric motor, a rotating body which can be driven via the electric motor, and at least one rope which is wound in sections around the rotating body.

Description

The invention relates to a lifting device comprising a fastening device for fastening to a ceiling and/or a wall.

Lifting devices are generally known. For example, a manual cable pull can be attached to a ceiling to lift an object. However, this requires a relatively high level of force.

It is therefore an object of the invention to provide a lifting device which can be operated in a force-saving manner.

This problem is solved by the subject matter and the method of the independent claims.

The lifting device according to the invention has a fastening device for fastening to a ceiling and/or a wall. The lifting device or at least a part thereof, e.g. a housing, can be fastened to the ceiling and/or wall via the fastening device.

For example, the fastening can be done using screws. This enables simple and cost-effective installation.

The lifting device also has an electric motor. This eliminates the need to lift the object manually. This allows an object to be lifted or lowered with minimal effort.

The lifting device has a rotating body, e.g. a roller, which can be driven and/or is driven by the electric motor.

For lifting, the rotating body is preferably rotated in a first direction. For lowering, however, the rotating body can be rotated in a second direction, for example. The first direction of rotation and the second direction of rotation are preferably opposite.

This allows the height of the object to be adjusted precisely.

The lifting device has at least one rope that is wound around the rotating body in sections. One end of the rope can be attached to the rotating body, e.g. glued and/or knotted.

A region of the rope, preferably an end region, preferably an end region facing away from the rotating body, is connected and/or connectable to the object to be lifted.

For example, the length of the rope can be chosen so that an object can be lifted up to 3 m.

Preferably, pulleys may be provided to bring the rope into the desired position.

The lifting device can be used in many different ways. For example, conventional ceiling dryers can be retrofitted with the lifting device. Laundry, such as shirts, T-shirts, dresses and/or other items of clothing, can be pulled up for drying and/or storage, e.g. in a changing room. A bicycle can also be pulled up, e.g. in a garage. The bicycle can be stored and/or serviced on the ceiling, for example.

Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

According to one embodiment, at least two ropes are provided, which are wound around the rotating body in sections in opposite directions.

One rope is preferably wound onto the rotating body from below and the other rope from above.

If the rotating body rotates in a first direction, both ropes are preferably paid out. If, however, the rotating body rotates in the second direction, both ropes are preferably taken in.

In each case, one region of the ropes, preferably an end region, preferably an end region facing away from the rotating body, is connected and/or connectable to the object to be lifted.

In this way, the object is held securely by two ropes.

More than two ropes, e.g. three or four ropes, can also be provided. Preferably, all ropes are wound in sections around the same rotating body. Alternatively, at least one rope can be wound in sections around an additional rotating body.

The ropes can preferably attack different positions on the same object.

According to a further embodiment, the electric motor can be operated in the low-voltage range.

Due to the low voltage, the lifting device can be used safely in damp rooms, for example.

The voltage can preferably be a maximum of 100 V, 50 V or 20 V. The voltage is preferably between 5 V and 15 V, e.g. 12 V.

The electric motor can be supplied with power via a power pack. Alternatively, an independent power supply is possible. For example, an accumulator, a battery and/or a solar module can be provided for this purpose. The solar module can, for example, have an output of 10 W.

According to a further embodiment, a housing is provided in which the electric motor and/or the rotating body are arranged.

Preferably, a control device for controlling the electric motor can also be provided in the housing. The control device is preferably a component of the lifting device.

The fastening device can be arranged on and/or in the housing and/or form part of the housing. For example, holes in the housing can be used for fastening to the ceiling and/or the wall.

The housing can, for example, have a maximum dimension of 30 cm x 15 cm x 10 cm, preferably 25 cm x 12 cm x 7 cm.

For example, the housing offers protection against moisture.

According to a further embodiment, a radio control device is provided for controlling the electric motor.

For this purpose, the control device of the lifting device can, for example, have a receiving device to receive the signals sent by the radio control device.

The radio control device allows the lifting device to be controlled remotely. This allows convenient control of the lifting device.

The term “radio” is to be understood broadly and includes all known and future wireless transmission technologies such as UMTS, GSM, LTE, e.g. LTE-Advanced or LTE-Advanced Pro, W-CDMA, e.g. HSPA, 3G, 4G, 5G, 6G, Bluetooth, infrared, WLAN, e.g. WiFi, ZigBee, NFC, Wibree, WiMAX, IrDA, optical radio link or the like.

A separate remote control can be provided as a radio control device. Control via a smartphone and/or a tablet PC is also conceivable.

As an alternative to a radio control device, a wired control can also be used.

The invention further relates to a drying device with a lifting device according to the invention and a suspension device which is connected to the rope.

The hanging device can, for example, be designed as a ceiling dryer.

For example, conventional suspension devices can be retrofitted with the lifting device.

Finally, the invention relates to a method for lifting an object, e.g. a suspension device, with a lifting device according to the invention.

The electric motor causes the rotating body to rotate and the rope, which is wound around the rotating body in sections, raises or lowers the object connected to the rope.

Whether the object is raised or lowered depends primarily on the direction of rotation of the rotating body.

The control can preferably be done via radio.

The object, e.g. a hanging device, can first be lowered. In this position it is easily accessible and can be loaded with laundry, for example. The object can then be raised so that it is no longer in the way.

All embodiments and components of the devices described here are preferably designed to be operated according to the method described here, e.g. by means of a control device. Furthermore, all embodiments of the devices described here and all embodiments of the method described here can be combined with each other, preferably also detached from the con specific design in which they are mentioned.

If a figure contains a reference symbol that is not explained in the directly associated description text, reference is made to the corresponding preceding or following statements in the figure description. The same reference symbols are used for identical or comparable components in the figures and these are not explained again.

1 shows a lifting device with a housing 10. An electric motor 12, a gear 14, a rotary body 16 and a control device 18 are arranged in the housing 10. A power supply 20 can be provided for the power supply. The voltage can be 12 V.

The control device 18 can be operated via a radio control device 22. The control device 18 then controls the electric motor 12.

Two ropes 24, 26 are wound around the rotating body 16. These can be guided to pulleys 28 which are placed outside the housing 10.

Recesses 30 are provided on the housing 10 as components of a fastening device 32 for fastening to a ceiling 34 or a wall 36, which in 2 are shown.

As in 2 As can also be seen, the end regions of the ropes 24, 26 can be connected to an object 38, e.g. a suspension device.

The suspension device 38 can thus be raised or lowered.

In 3 an alternative suspension device 38 is shown.

According to 4 the hanging device 38 can have a rod for coat hangers 40.

It is like in 5 As shown, it is also possible for other objects, e.g. a bicycle 42, to be lifted.

As in the 6 and 7 As shown, four ropes 24, 26, 44, 46 may be provided.

In 8 It is shown that a power supply via a solar module 48 and/or a battery 50, e.g. a 12 V battery, is possible. The lifting device can therefore work independently.
