Description

[0001] The invention relates to a lifting device comprising a fastening device for fastening to a ceiling and / or a wall.

[0002] Lifting devices are generally well known. For example, a manual cable pulley can be attached to a ceiling to lift an object. However, this requires a comparatively high level of force.

[0003] It is therefore an object of the invention to provide a lifting device which can be operated in a force-saving manner.

[0004] This problem is solved by the subject matter and the method of the independent claims.

[0005] The lifting device according to the invention comprises a fastening device for attachment to a ceiling and / or a wall. The lifting device or at least a part thereof, e.g., a housing, can be attached to the ceiling and / or wall via the fastening device.

[0006] For example, the mounting can be done using screws, allowing for simple and cost-effective installation.

[0007] The lifting device also features an electric motor. This eliminates the need for manual lifting of the object. This allows for effortless lifting and lowering of the object.

[0008] The lifting device has a rotating body, e.g. a roller, which can be driven and / or is driven by the electric motor.

[0009] For lifting, the rotating body is preferably rotated in a first direction. For lowering, however, the rotating body can be rotated, for example, in a second direction. The first and second directions of rotation are preferably opposite.

[0010] This allows the height of the object to be adjusted precisely.

[0011] The lifting device comprises at least one rope, which is wound in sections around the rotating body. One end of the rope can be attached to the rotating body, e.g., glued and / or knotted.

[0012] 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.

[0013] For example, the length of the rope can be chosen so that an object can be lifted up to 3 m.

[0014] Preferably, pulleys may be provided to bring the rope into the desired position.

[0015] The lifting device has a wide range of applications. For example, conventional ceiling dryers can be retrofitted with the lifting device. Laundry, such as shirts, T-shirts, dresses, and / or other clothing items, can be hoisted up for drying and / or storage, e.g., in a changing room. Furthermore, a bicycle, for example, can be hoisted up in a garage. The bicycle can be stored and / or serviced on the ceiling, for example.

[0016] Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

[0017] According to one embodiment, at least two ropes are provided, which are wound in sections in opposite directions around the rotating body.

[0018] One rope is preferably wound onto the rotating body from below and the other rope from above.

[0019] If the rotating body rotates in a first direction, both ropes are preferably paid out. If the rotating body rotates in the second direction, both ropes are preferably retracted.

[0020] 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.

[0021] In this way, the object is held securely by two ropes.

[0022] More than two cables, e.g., three or four cables, can also be provided. Preferably, all cables are wound in sections around the same rotating body. Alternatively, at least one cable can be wound in sections around an additional rotating body.

[0023] The ropes can preferably attach to different positions of the same object.

[0024] According to a further embodiment, the electric motor can be operated in the low-voltage range.

[0025] Due to the low voltage, the lifting device can be used safely in damp rooms, for example.

[0026] 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.

[0027] The electric motor can be powered by a power supply. Alternatively, a standalone power supply is possible. For example, an accumulator, a battery, and / or a solar module can be provided. The solar module can, for example, have an output of 10 W.

[0028] According to a further embodiment, a housing is provided in which the electric motor and / or the rotating body are arranged.

[0029] 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.

[0030] The mounting device can be located on and / or in the housing and / or form part of the housing. For example, holes in the housing can be used for mounting to the ceiling and / or wall.

[0031] The housing can, for example, have dimensions of a maximum of 30 cm x 15 cm x 10 cm, preferably 25 cm x 12 cm x 7 cm.

[0032] For example, the housing offers protection against moisture.

[0033] According to a further embodiment, a radio control device is provided for controlling the electric motor.

[0034] 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.

[0035] The radio control device allows the lifting device to be controlled remotely. This allows for convenient control of the lifting device.

[0036] 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 links or the like.

[0037] A separate remote control can be provided as a radio control device. Control via a smartphone and / or tablet PC is also conceivable.

[0038] As an alternative to a radio control device, a wired control can also be used.

[0039] 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.

[0040] The hanging device can, for example, be designed as a ceiling dryer.

[0041] For example, conventional suspension devices can be retrofitted with the lifting device.

[0042] Finally, the invention relates to a method for lifting an object, e.g. a suspension device, with a lifting device according to the invention.

[0043] The electric motor causes the rotating body to rotate and the rope, which is wound sectionally around the rotating body, lifts or lowers the object connected to the rope.

[0044] Whether the object is raised or lowered depends primarily on the direction of rotation of the rotating body.

[0045] The control can preferably be done via radio.

[0046] The object, such as 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.

[0047] All embodiments and components of the devices described here are preferably designed to be operated, e.g., by means of a control device, according to the method described here. Furthermore, all embodiments of the devices described here, as well as all embodiments of the method described here, can be combined with one another, preferably independently of the specific embodiment in whose context they are mentioned.
