Description

Clothes horse for drying laundry and drive therefor

The present invention relates to a clothes horse for drying

Laundry according to the preamble of claim 1 and a drive for a drying rack according to claim 12.

Laundry racks of the generic type are used inside a room or in the open air, for example on a terrace or balcony, to hang laundry on rod-shaped or line-shaped support elements so that the moisture can escape from the laundry. Accordingly, the

Laundry rack a frame for placing the laundry rack on the floor and a plurality of support elements extending in the direction of a longitudinal axis in the form of rods or lines for hanging up the laundry. Such a clothes horse is described for example in DE 203 20 864 U1.

The frame of such a clothes horse as the present invention

particularly concerns, is usually designed to be hinged to the

Clothes horse from a use position to a stowed position

spend in which he comparatively less space than in the

Occupies position of use. For example, reference is made to DE 20 2014 103 557 U1. In the drying rack disclosed here, side parts can also be removed,

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

Frequently, the frame of corresponding clothes horse, as is also preferred in the present invention, has two feet, each of which comprises a cross strut that 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 clothes horse with an electric motor drive are known to unfold the frame or the laundry from a

To move the rain-protected area under a roof into an outside area, see DE 20 2008 000 353 U1.

Laundry racks of the generic type have the disadvantage that the time required for the hanging laundry to dry completely is comparatively long. For example, it usually takes over 12 hours to complete

comparatively heavy items of laundry, such as jeans, have dried. The drying time of lighter items of laundry,

for example T-shirts, is slightly shorter and lasts for example 6 to 8 hours. If the clothes horse is set up with the laundry inside a living room, the comparatively long drying time is annoying because the clothes horse is "in the way".

GB 2 342 573 A discloses one equipped with a rotary drive

Clothes horse that can be rotated to reduce the drying time of the laundry.

The present invention is based on the object of specifying a clothes horse that can be set up easily and flexibly in a room and advantageously in a comparatively space-saving stowed position, and with which the drying time for the laundry is significantly reduced.

The object of the invention is achieved by a clothes horse with the

Features of claim 1 and a drive for such a clothes horse according to the features of claim 12 solved. In the dependent claims, advantageous and particularly expedient embodiments of the invention are specified. A clothes horse according to the invention for drying laundry has a frame for placing the clothes horse on a floor and at least one or a plurality of rod-shaped or line-shaped support elements which are mounted in the frame and extend in the direction of a longitudinal axis for hanging up the laundry. The frame is advantageously collapsible and / or divisible in order to move it from a position of use into a space-saving stowed position. This is usually done manually.

According to the invention, the clothes horse is assigned a drive which engages the frame or a part of the frame with the support element or elements in order to reciprocally move the frame or the part of the frame for pivoting laundry suspended on the support element or elements.

The laundry rack according to the invention or its frame or the part of the frame and the support element (s) 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 exclusively 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. As a result, a particularly pronounced pendulum movement of the laundry items is possible without them being compressed when pendulum, which increases the effectiveness.

With the solution according to the invention, the drying time can be shortened in particular by 50% to 70%, compared to a drying time in which the laundry suspended on the support element is not moved. For example, jeans can take 3 hours to dry and T-shirts can take 2 hours to dry. According to an advantageous embodiment, the drive is connected to the frame or the part of the frame in such a way that it impresses a linear alternating movement on the frame or the part of the frame, in particular perpendicular to the longitudinal axis of the support element or elements.

According to one embodiment of the invention, the drive is arranged externally to the frame in such a way that it impresses an alternating movement on the frame as a whole. According to an alternative embodiment, the drive is arranged between frame parts to the part of the frame with the or the

To impress support elements an alternating movement relative to another part of the frame.

According to one embodiment, the drive is at least indirectly mounted on the floor and actuates the frame in order to impress the alternating movement on it. According to an alternative embodiment, the drive is on the frame

connected and supported at least indirectly on the ground. This means that the drive is moved with the frame.

For example, in order to be able to move the entire frame back and forth, rollers can be arranged at the bottom end of the frame and the drive engages the frame in order to roll it back and forth over the rollers. Another possible embodiment provides that a rocker is provided on the bottom of the frame and the drive engages the frame in order to rock the frame back and forth.

If only part of the frame with the support element or elements is moved back and forth, for example a field of the support elements, in particular a line field, can be provided that reciprocally and in particular linearly moves back and forth. 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 alternately tilted about a tilting axis . The tilt axis can extend along the floor at a floor-side end of the frame. For example, the drive engages one axial end of a foot and the tilt axis runs along the opposite axial end of the foot.

However, the drive could also act on the frame outside of a foot or feet in order to generate 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 engages the frame at the level of the support elements.

The frame preferably comprises two feet, each of which has a foot strut that 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 it at one axial end.

The drive has, for example, a housing that includes a receiving space that is open to the environment and in which part of the frame, in particular a foot strut, can be used. In or on the receiving space, a pivoting device driven by a drive device, for example a motor, in particular an electric motor, can be provided on which the part of the frame, in particular the foot strut, can be placed and / or in 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 clothes horse has a housing which encloses a receiving space that is open to the environment, and also a Drive device and one arranged in or on the receiving space

Swivel device. A frame is on the swivel device

The clothes horse can be placed on 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 pivoting device is connected to the drive device in such a way that it is driven by the drive device to perform an alternating movement. As a result, the laundry hanging on the clothes horse, as explained, can be put into a

Pendulum movement are offset.

The drive device can be designed, for example, in the form of a motor with a rotating output shaft or comprise one. However, other drive devices that are driven, for example, with electrical power or hydraulically or pneumatically, are also possible. In particular, the drive device can also comprise an actuator actuated by magnetic force, whereby, for example, the alternating 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 explained below using an electric motor drive.

According to an advantageous embodiment of the invention, the

Pivoting device a trough-shaped rocker that delimits the receiving space from below and one axial end of which by means of the drive device

is reciprocally movable up and down. The channel is therefore preferably open at the top 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, on the output shaft of the drive device is a

Eccentric disc is provided on which the shaft is eccentrically and rotatably mounted.

The drive device is preferably designed as an electric motor and can get by with a comparatively low 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.

The drive can be made waterproof, so that from the laundry

escaping moisture cannot penetrate the drive.

According to one embodiment of the invention, the said drive is assigned to a foot of the frame and a tilting bearing is assigned to another foot of the frame, which ensures that the frame is in a safe position when it is driven. The tilting bearing can, for example, have a housing corresponding to the drive, in particular with a channel-shaped rocker arranged therein, which receives a foot strut. However, the

Drive device is omitted here.

The invention is to be described below by way of example with the aid of exemplary embodiments and the figures.

Show it: FIG. 1 shows a schematic representation of an exemplary embodiment for a clothes horse according to the invention;

FIG. 2 shows an alternative design to FIG. 1; FIG. 3 shows an exemplary representation of a drive according to the invention for a clothes horse;

FIG. 4 shows the rocker of a drive according to FIG. 3; Figure 5 is a schematic representation of the rocker drive in one

Plan view in the longitudinal direction;

Figure 6 shows the rocker drive from Figure 5 in a view along the

Transverse direction;

FIG. 7 shows a modified form of the rocker drive; FIG. 8 shows an embodiment in which only part of the frame is moved; FIG. 9 shows an embodiment of a frame with rollers;

Figure 10 shows an embodiment of the frame with a rocker on the frame. FIG. 1 shows an example of a clothes horse 1, comprising a frame 2 and a plurality of rod-shaped or line-shaped support elements 3 for hanging up the laundry W. A drive 4 engages the frame 2 so that it can pivot laundry suspended on the support elements 3 W is moved and thereby the drying time of the laundry W is shortened. The support elements extend in the direction of a longitudinal axis X. The pendulum axis P, around which the laundry W by the movement of the frame 2 by means of the

Drive 4 oscillates, runs parallel to the longitudinal axis X.

The frame is tilted back and forth about a tilt axis K. The tilt axis K is arranged at the axial end of foot struts 6 of the feet 5, the foot struts 6 running along a transverse axis Y which is perpendicular to the longitudinal axis X. The frame 2 is placed on a floor B with the foot struts 6.

The drive 4 is shown here as an example of a piston drive. Other

Drive forms come into consideration. In the exemplary embodiment according to FIG. 1, the drive 4 engages the frame 2 outside the feet 5.

In the embodiment shown by way of example in FIG. 2, the drive 4 engages a foot 5 of the frame 2. For this purpose, the foot strut 6 is inserted into a receiving space 8 within a housing 7 of the drive 4. In the receiving space 8 or adjacent to it is one

Pivoting device 10 is provided, which causes the frame 2 to tilt about the tilt axis K. Accordingly, the drive 4 has a motor which is not yet shown in detail in FIG.

Further possible details of the drive 4 from FIG. 2 are explained with reference to FIGS. 3 to 7. The pivoting device 10 thus comprises a rocker 11 which delimits the receiving space 8 from below. As indicated schematically in FIG. 3 by the dashed line, the foot strut 6 is in the rocker 11

applicable. The rocker 11 is alternating within the housing 7

driven in order to tilt the frame 2 alternately about the tilting axis K, see FIG. 2.

For this tilting movement, the rocker 11 is via an eccentric drive 12 on a motor 9, which is designed in particular as an electric motor, connected, see Figures 5 and 6. The motor 9 has an output 9.1, which drives an eccentric 12.1. Eccentrically to the output 9.1 of the motor 9, a shaft 14 is connected to the eccentric disk 12.1 and carries the rocker 11 at least indirectly. The shaft 14 is positioned in the area of one axial end of the rocker 11, this axial end being opposite the tilting axis K, see FIG. 2.

By driving the shaft 14 via the eccentric disk 12.1, the shaft 14 is alternately moved up and down. As a result, this up and down movement also becomes the corresponding associated axial end of the rocker 11

imprinted. When the rocker 11 rests freely on the shaft 14, a

Sliding movement between the underside of the rocker 11 and the shaft 14 occur, so that the rocker 11 performs a pure tilting movement about a tilting axis. If, as indicated in FIG. 7, a receptacle 15 surrounding the shaft is mounted on the underside of the rocker 11, for example in the form of a round frame in which a ball bearing is installed, and the rocker 11 is thus positively connected to the shaft 14 is, then the rocker 11 performs a back and forth movement in addition to the up and down movement, see the arrows in FIG.

As indicated in FIG. 2, a tilting bearing 13 can be provided on the second foot strut 6, which is not inserted into the housing 7 of the drive 4. With the exception of the motor 9 and the eccentric drive 12, this tilting bearing 13 can be designed at least essentially identical to the drive 4.

In particular, a corresponding rocker is also provided in which the foot strut 6 is inserted and which executes the movement of the rocker 11 of the drive 4 in parallel. This makes it possible to achieve greater stability of the frame 2 during movement.

The drive 4 is advantageously designed universally so that different feet 5 or foot struts 6 differently designed frames 2 of clothes horse 1 in the receiving space 8 can be used. It is done accordingly

Insertion of the foot 5 or the foot strut 6 in the receiving space 8 or the rocker 11 advantageously free. Assembly is not necessary. In Figure 8, an embodiment of the clothes horse 1 is shown schematically, in which only a part of the frame 2, which includes the support elements 3, with the drive 4 relative to another part set up on a floor or also, for example, part of the Frame 2 is reciprocally moved back and forth.

In the embodiment according to FIG. 9, the frame has bottom-side rollers 16 and the drive 4 engages the frame 2 in order to make it as a whole

to move alternately back and forth over the rollers 16. In the embodiment according to FIG. 10, the frame 2 has a

rocker on the bottom and the drive 4 engages the frame 2 in order to rock this reciprocally back and forth.
