Abstract

The invention relates to a clothes horse for drying laundry with a frame for placing the clothes horse on a floor and with a plurality of rod-shaped or linen-shaped support elements extending in the direction of a longitudinal axis for hanging the laundry (W).

Description

The present invention relates to a drying rack for drying laundry according to the preamble of claim 1 and a drive for a drying rack according to claim 6.

Generic laundry racks are used inside a room or outdoors, for example on a terrace or a balcony, to hang laundry on rod-shaped or linen-shaped support elements so that the moisture can escape from the laundry. Correspondingly, the laundry racks have a frame for placing the laundry rack on the floor and a multiplicity of support elements which extend in the form of a rod or line in the direction of a longitudinal axis for hanging the laundry. Such a clothes horse is for example in DE 203 20 864 U1 described.

The rack of such drying racks, as they relate in particular to the present invention, is usually designed to be foldable in order to move the drying rack from a use position into a stowage position in which it takes up comparatively less space than in the use position. For example, on DE 20 2014 103 557 U1 referred. In the laundry rack disclosed here, additional side parts are removable,

The distance between the support elements can be constant or adjustable, such as in DE 20 2016 008 152 U1 is described.

Often, the frame of corresponding drying racks, as is also preferred in the case of the present invention, has two feet, each of which comprises a cross strut which can be set up transversely on the floor. However, other frames are also known, see for example DE 10 2006 053 981 A1 .

Furthermore, automatic laundry racks with an electric motor drive are known in order to unfold the frame or to move the laundry from a rain-protected area under a roof to an outside area, see DE 20 2008 000 353 U1 .

Generic laundry racks have the disadvantage that the time required for the laundry to dry completely is comparatively long. For example, it usually takes over 12 hours for comparatively heavy items of laundry, such as jeans, to dry. The drying time of lighter items of laundry, such as T-shirts, is somewhat shorter and is, for example, 6 to 8 hours. If the drying rack with the laundry is set up inside a living room, the comparatively long drying time is annoying, since the drying rack “stands in the way”.

The present invention is based on the object of specifying a clothes horse which, on the one hand, can be set up easily and flexibly in a room and which can advantageously be moved into a comparatively space-saving stowage position, and on the other hand which significantly shortens the drying time for the laundry.

GB 2 342 573 A discloses a clothes horse equipped with a rotary drive which can be rotated as a whole to reduce the drying time of the laundry.

The object of the invention is achieved by a clothes horse with the features of claim 1 and a drive of a clothes horse according to the features of claim 6. Advantageous and particularly expedient embodiments of the invention are specified in the dependent claims.

A laundry rack according to the invention for drying laundry has a frame for placing the laundry rack on a floor and a multiplicity of rod-shaped or linen-shaped support elements extending in the direction of a longitudinal axis for hanging the laundry. The frame is advantageously collapsible and / or divisible in order to move it from a use position into a space-saving stowed position. This is usually done manually.

A drive is assigned to the clothes horse, which acts on the frame in order to move it to pivot laundry hanging on the support element.

The clothes horse according to the invention or its frame and the support elements are accordingly moved by the drive in such a way that the laundry suspended on the support element is pivoted, in contrast to a movement of the laundry only in one direction. A pendulum movement is preferably impressed on the laundry, that is, the laundry is pivoted back and forth.

The pendulum axis of the pendulum movement is preferably parallel to the longitudinal axis along which the support elements extend. This enables a particularly pronounced pendulum movement of the laundry items without them being compressed during commuting, which increases the effectiveness.

By means of the solution according to the invention, the drying time can in particular be increased by 50% to 70% can be shortened compared to a drying time at which the laundry suspended on the support element is not moved. For example, the drying time of jeans 3rd Hours and the drying time of T-shirts 2nd Hours.

According to a preferred embodiment of the invention, the frame has at least one foot and the drive engages the frame, in particular the foot, in order to move the frame, and in particular the foot, up and down, so that the frame is mutually tilted about a tilt axis . The tilt axis can extend along the bottom at a bottom end of the frame. For example, the drive engages an axial end of a foot and the tilt axis runs along the opposite axial end of the foot.

However, the drive could also engage outside of a foot or feet on the frame in order to produce the desired pendulum movement, for example in the area of a vertical center of the frame or in the area of an upper end of the frame. According to one embodiment, the drive acts on the frame at the level of the support elements.

The frame preferably comprises two feet, each of which has a foot strut which extends horizontally along a transverse axis and can be placed on the floor. The drive can then engage at least one of the foot struts in order to alternately raise and lower them at one axial end.

The drive has, for example, a housing which comprises a receiving space which is open to the surroundings and in which a part of the frame, in particular a foot strut, can be used. A swiveling device driven by a drive device, for example a motor, in particular an electric motor, can be provided in or on the receiving space, onto which the part of the frame, in particular the foot strut, can be placed and / or into which the part of the frame, in particular the foot strut, can be clamped and / or on which the part of the frame, in particular the foot strut, can be mounted.

A drive according to the invention for a laundry rack has a housing which encloses a receiving space which is open to the environment, a drive device and a pivoting device arranged in or on the receiving space. A frame of the clothes horse can be placed on the swivel device and / or a frame of the clothes horse can be clamped into the swivel device and / or a frame of the clothes horse can be mounted on the swivel device. The swivel device is connected to the drive device in such a way that it is driven by the drive device in order to carry out an alternating movement. As a result, the laundry suspended on the drying rack can be set in a pendulum motion.

The drive device can be designed, for example, in the form of a motor with a rotating output shaft or can include such a shaft. However, other drive devices that are driven, for example, with electrical current or hydraulically or pneumatically are also possible. In particular, the drive device can also comprise an actuator actuated by magnetic force, for example the reciprocal polarity reversal of a magnet at the axial end of a rocker or of two magnets at both axial ends of a rocker generates a rocking movement, in particular as will be explained below using an electromotive drive.

According to an advantageous embodiment of the invention, the swivel device comprises a trough-shaped rocker which delimits the receiving space from below and one axial end of which can be moved up and down alternately by means of the drive device. The channel is therefore preferably opened upwards, so that the frame, in particular a cross strut of the base of the frame, can be inserted into the channel, in particular can be placed loosely in the channel.

For example, the drive device is connected to the rocker via an eccentric drive.

A bushing is advantageously provided at the bottom of the rocker, in which a shaft is rotatably mounted, in particular by means of a roller bearing, and the shaft is arranged as a crank of an eccentric drive of the drive device.

In particular, an eccentric disk is provided on the output shaft of the drive device, on which the shaft is mounted eccentrically and rotatably.

The drive device is preferably designed as an electric motor and can manage with a comparatively small drive power, for example from 5 to 15 watts, in particular from 8 to 11 watts. A rechargeable battery is preferably assigned to the motor in order to supply the motor with electrical power. Charging can be inductive or wired.

According to one embodiment of the invention, the mentioned drive is assigned to a foot of the frame and a tilting bearing is assigned to another foot of the frame, which ensures a secure position Stand of the frame guaranteed when it is driven. The tilting bearing can, for example, have a housing corresponding to the drive, in particular with a trough-shaped rocker arranged therein, which receives a foot strut. However, the drive device can be omitted here.

The invention will be described below using exemplary embodiments and the figures as examples.

In the 1 is a clothes horse 1 exemplified, comprising a frame 2nd and a plurality of rod-shaped or line-shaped support elements 3rd for hanging up the laundry W . A drive 4th grips the frame 2nd so that it can be swiveled onto the support elements 3rd hanging laundry W is moved and thereby the drying time of the laundry W is shortened.

The support elements run in the direction of a longitudinal axis X . The pendulum axis P around which the laundry W by the movement of the frame 2nd by means of the drive 4th oscillates, runs parallel to the longitudinal axis X .

The frame is about a tilt axis K tilted back and forth. The tilt axis K is at the axial end of foot braces 6 the feet 5 arranged, the foot struts 6 along a transverse axis Y that are perpendicular to the longitudinal axis X is gone. With the foot braces 6 is the frame 2nd on a floor B put on.

The drive 4th is shown here as an example as a piston drive. Other forms of drive are possible. In the embodiment according to the 1 the drive engages 4th outside the feet 5 on the frame 2nd on.

In the exemplary in the 2nd illustrated embodiment engages the drive 4th on one foot 5 of the frame 2nd on. This is the foot brace 6 in a recording room 8th inside a housing 7 of the drive 4th used. In the recording room 8th or adjacent to this is a swivel device 10th provided a tilting of the frame 2nd about the tilt axis K causes. The drive accordingly 4th an engine on in the 2nd is not yet shown in detail.

Further possible details of the drive 4th from the 2nd are based on the 3rd to 7 explained. So includes the swivel device 10th a seesaw 11 that the recording room 8th limited from below. In the seesaw 11 is like in the 3rd schematically indicated by the dashed line, the foot strut 6 applicable. The seesaw 11 is inside the case 7 alternately driven to the frame 2nd alternately around the tilt axis K to tilt, see the 2nd .

The rocker is for this tilting movement 11 via an eccentric drive 12th on an engine 9 , which is designed in particular as an electric motor, see the 5 and 6 . The motor 9 has an output 9.1 on which is an eccentric disc 12.1 drives. Off-center to the output 9.1 of the motor 9 is on the eccentric disc 12.1 a wave 14 connected which the seesaw 11 at least indirectly. The wave 14 is in the area of an axial end of the rocker 11 positioned, this axial end of the tilt axis K is opposite, see the 2nd .

By driving the shaft 14 over the eccentric disc 12.1 becomes the wave 14 alternately moved up and down. This also corresponds to the corresponding assigned axial end of the rocker 11 imprinted this up and down movement. If the seesaw 11 free on the wave 14 there can be a sliding movement between the underside of the rocker 11 and the wave 14 occur so that the seesaw 11 executes a pure tilting movement about a tilting axis. If, as in the 7 is indicated on the underside of the seesaw 11 a recording enclosing the wave 15 is mounted, for example in the form of a round frame in which a ball bearing is installed, and the rocker 11 thus form-fitting with the shaft 14 is connected, so the seesaw leads 11 in addition to the up and down movement also a back and forth movement, see the arrows in the 7 .

Like in the 2nd is indicated, can on the second foot brace 6 that are not in the housing 7 of the drive 4th is used, a tilting bearing 13 be provided. This tilting position 13 can down to the engine 9 and the eccentric drive 12th at least essentially identical to the drive 4th be executed. In particular, a corresponding rocker is also provided, into which the foot strut 6 is inserted and which the movement of the seesaw 11 of the drive 4th executes in parallel. This can increase the stability of the frame 2nd be achieved during movement.

The drive 4th is advantageously designed so universally that different feet 5 or footstays 6 different frames 2nd of drying racks 1 in the recording room 8th can be used. The foot is inserted accordingly 5 or the foot strut 6 in the recording room 8th or the seesaw 11 advantageously free. Assembly is not necessary.
