Description

DEVICE FOR STORING AND MOVING OBJECTS

The invention relates to a device for storing and moving objects.

Numerous devices for storing and moving objects are known.

DE 297 12 495 UI describes a rotatable laundry screen which is driven by means of a drive system, the power of which is provided by a manually prestressed tension, compression or torsion spring.

From DE 195 22 236 AI a rotary drive for a clothes dryer is known which has a motor which is accommodated in a housing which is inserted into the bottom sleeve of the clothes dryer and in the upper part receives the standpipe of the clothes dryer to be rotated. The torque is transmitted from the motor to the standpipe via a gearbox, the output shaft of which is connected to the standpipe of the clothes dryer via a V-belt. A freewheel is provided in the pulley provided on the standpipe, which enables the laundry spider to be rotated manually counter to the drive direction.

The object of the invention is to provide a device for the advantageous storage and movement of objects.

This object is solved by the features of claims 1, 26 and 36. According to claim 1, the claimed device for storing and moving objects has a motor and a holder, which one Alignment device for vertical alignment of a driven shaft, to which the object or objects are attached in a rotationally fixed manner.

The alignment device makes it possible to align the shaft causing the rotation of the object vertically and thus to avoid that an unnecessarily high drive torque is required to rotate the object due to an inclined position of the shaft. The vertical alignment ensures that the center of gravity of the object to be rotated is always at the same level during one revolution and therefore no lifting work has to be carried out which leads to an increase in the drive torque. In this way, the object can be rotated with a particularly low drive power.

The alignment device can have a bearing which allows the shaft to be pivoted. This can be a ball-like rolling or sliding bearing, the bearing shells of which can be rotated. The bearing can be provided above the center of gravity of the unit to be rotated, which results in an automatic alignment of the unit due to the weight. If the shaft is mounted below the unit, an adjustment device for adjusting the vertical alignment must be provided.

Independent of the bearing of the shaft, an adjusting device can be provided, by means of which the bearing of the shaft can be adjusted in at least two axes. For this purpose, for example, a fixed axis can be provided, which is aligned by the adjusting device and which supports the bearings for supporting the shaft. According to claim 26, the device is provided with a receptacle for receiving objects such as laundry, which is carried by a movable holder, the holder being attachable to the ceiling of a room and having an adjustable length, the holder being driven by an electric motor .

This construction allows the movement of objects, such as laundry to be dried, the holder having an adjustable length to improve operability or to adapt to the spatial conditions.

According to claim 36, the device is provided with a receptacle for receiving objects such as laundry, which is carried by a movable holder which can be attached to the ceiling or a wall and has at least two arms, at least one of which can be pivoted by an electric motor drive is.

This construction allows the movement of objects such as laundry to be dried, whereby the objects are pivoted and good operability and space utilization is achieved by providing a pivoting position in which the device is easy to load and unload and the device When not in use in one end position, it can be kept on the wall or ceiling to save space.

The shaft is expediently driven by a motor and a slip clutch. Such a design has several major advantages. By means of a suitable slip clutch, a motor can be used whose starting torque would not be sufficient to set the object in rotation. However, the starting torque is sufficient to cause the clutch to slip and through this sliding a certain moment is transferred to the shaft of the object to be rotated by means of sliding friction. When a certain rotational speed of the object is reached, the slipping of the clutch is stopped and the object is driven by the motor without slipping. In this way, a comparatively weak motor can be used that consumes little electricity. A simple, extremely advantageous coupling is described in detail using the exemplary embodiments.

Furthermore, the slip clutch allows the object to be stopped without problems. With manual intervention in the rotation, the maximum torque that can be transmitted by the clutch is exceeded, the clutch slips and the motor turns idle. This is advantageous for various areas of application and may also be desirable for safety reasons.

A friction wheel pretensioned by means of a pretensioning device can be provided as the slip clutch. The motor can interact via a friction wheel with a disk-like or pot-like element that is connected to the shaft in a rotationally fixed manner. The element can be made of metal or plastic. It can be formed in one piece or can be formed by a multi-piece construction by means of welding or screwing. However, it can also be connected in a rotationally fixed manner in kinematic reversal to the motor and the friction wheel and this can interact with a fixed ring-like, disc-like or pot-like element.

The motor can also cooperate with an element connected to the shaft via a slip clutch. In this case, the slip clutch is provided between the element and the shaft. However, it is also possible to use a motor which acts on the element to be moved without a clutch and is designed in such a way that it delivers the necessary torque but can be stopped at any time by hand, which can also achieve the advantages described.

The motor expediently interacts with the outer region of the ring-like, disk-like or pot-like element via an engagement element, the radius of the engagement being adjustable in order to adjust the rotational speed and possibly. adjust the drive torque. For this purpose, the motor can, for example, be mounted on a support with the friction wheel producing the engagement and serving as a slip clutch, by means of which the position of the motor or the friction wheel can be adjusted in order to enable engagement on different radii of the disk or cup-like element .

The motor and a drive element for transmitting the motor torque to the shaft can be mounted on a pivotable arm and the weight of the motor can be used to pretension the drive element.

The motor and the drive element for transmitting the motor torque to the shaft can also be mounted on a displaceable or a pivotable arm which can be displaced or pivoted by means of a resilient element for prestressing the drive element.

According to a preferred embodiment, the motor is designed as a tubular motor. This enables a particularly compact structure to be achieved. To transmit the torque from the motor to the shaft, the motor shaft can be connected to an element having a threaded rod be part of the slip clutch. This connection can be positive or non-positive. The threaded rod expediently has at least one flattened side for transmitting the torque to a transmission element.

Friction disks have proven themselves as friction elements, although several friction disks can also be used to transmit larger moments. In most cases, however, pinching the drive element between two friction disks should be appropriate.

In order to generate the necessary pressure force of the friction disc, it can be preloaded by means of a spring. For this purpose, a spring placed on the threaded rod can be provided, which is pretensioned by means of a nut that can be screwed onto the threaded rod. However, other devices generating a corresponding pressure force, for example hydraulic devices, can also be provided.

The torque is expediently transmitted from the slip clutch to the shaft to be rotated via a suitable connecting element which is driven by the slip clutch. For this purpose, a connecting element can be provided, which is in engagement with an element of the slip clutch. The connecting element can be non-positively connected to an inner surface of the shaft with an outer peripheral surface. However, an element can also be used which is brought into positive engagement with the shaft to be rotated. The connecting element can also be connected to the shaft via connecting means such as screws. The tubular motor can be provided together with a device supporting the shaft on an axis that can be received by a floor mounting. In the case of relatively light objects to be rotated, however, it is also possible to dispense with a special bearing for the shaft and these are simply stored on the slip clutch or also on the housing of the tubular motor.

The floor mounting can have a clampable adjusting disc for aligning the axis. However, adjusting screws or other adjustment devices can also be provided.

It is advisable to provide an anti-rotation device on the axle and the floor mounting to secure the axle against turning. With only low torques, such a lock can be dispensed with if there is no reason to fear that the axis will rotate due to the friction occurring in the bearing of the axis.

A centering device for centering the axis in the floor mounting can be provided. This can be designed so that the axis is automatically centered when inserted into the floor mounting.

Since the construction is designed for minimal power consumption, the device described is particularly suitable for being fed by a solar module. A wide variety of applications are possible: For example, as a rotatable clothes dryer, carousel, rotatable hammock, but also as an irrigation pump, whereby a small but steady flow rate can be pumped using a low-performance pump. Applications in the area of decoration and presentation, for example as a plant roundabout or sales stand, are also possible, especially since - as described - the device can be stopped by one person without problems, without having to be switched off.

The invention can also be modified to move laundry or other items to be dried.

Experiments have shown that the drying time of the laundry can be drastically reduced when it is moved. The described device for fast drying of the laundry has only a low power requirement and effects a much more gentle drying of the laundry than is the case with tumble dryers.

Constructions for receiving and possibly also moving laundry can in principle also be used for receiving and moving other objects. For example, sales stands or presentation devices can be constructed in the same way.

By means of the invention, a device can be created which can be installed in rooms and, with comfortable handling, enables objects attached to the device to move.

Such a device can be fastened to the ceiling of a room and can be set in rotation by means of an electric motor drive. The length of the holder of the device can be changeable in order to be able to position the objects, for example laundry, at a certain height or to be able to adjust the height for easier handling.

The length of the holder can be increased by means of coupling elements that can be coupled, which can also be connected to one another. be changeable. These elements can be coupled to each other by means of a bayonet catch on the holder. However, snap locks or other positive or non-positive connections can also be used.

The length of the holder can be changed by means of a joint parallelogram. The length can be fixed for use of the device. However, this can also be adjusted while the device is in use. For example, the device can be lowered further by means of the mechanism for loading the device, and can be raised again when the device is in operation.

An articulated parallelogram is expediently provided with two pairs of parallelogram rods which are connected in an articulated manner, parallel guidance being achieved by means of a toothing of opposing rods. Such a construction is explained in more detail using an exemplary embodiment.

In particular in the case of the parallelogram mechanism mentioned, but also in the case of other devices having the same effect, it is advantageous to provide at least one resilient element which exerts an upward force on the receptacle receiving the objects in order to relieve the weight.

As an alternative or in addition to the above-mentioned devices for changing the length of the holder, a spindle with an associated spindle nut can be provided, with which the length of the holder can also be changed. The advantages that can be achieved with such a mechanism are discussed in more detail in the description of the figures. The spindle can be provided on the side of the receptacle and the spindle nut on the side of the holder or vice versa.

The spindle-spindle nut pairing can be designed to be self-locking, so that a set length of the holder is also retained, but can also be designed without self-locking, which offers advantages in handling, which will be discussed in more detail in connection with a preferred embodiment. If no self-locking is provided, the direction of rotation of the spindle and the drive can be selected so that when the holder is driven by the resistance acting on the spindle, a circumferential force is exerted on the spindle which turns the spindle into the spindle nut and thus the length of the holder shortened.

A modified device can be designed such that it is suitable for mounting on the ceiling or a wall. In this device, the objects are swung back and forth by a suitable drive, whereby laundry, for example, dries faster. Such devices can also be used for product presentation. The receptacle for receiving the objects can be articulated on the holder by means of arms.

The receptacle can be tiltably mounted on the holder and can be locked in at least one position. For example, laundry spiders from tumble dryers should be aligned horizontally. However, if the device is attached to the wall and pivoted back and forth by two arms mounted on the wall attachment, it may be advantageous to tilt the actual laundry receptacle, since it can then be tilted from the horizontal position into a vertical position when not in use the Recording parallel to the wall by swiveling the arms close to the wall to save space.

A simple pivoting can be achieved if an arm is pivoted from the drive by means of a connecting rod-like lever, this lever being articulated on the arm or being guided in a guide.

Figures 1 to 3 describe an embodiment in which the object to be rotated hangs on a frame 20. The object, not shown, is suspended via a shaft 1 which is set in rotation by the drive unit. The shaft 1 is pivotally received in a flange bearing 18 which is mounted in the uppermost region of the frame 20. As can be clearly seen from FIG. 3, a plate 22 is welded in the upper region of the frame 20, which is provided with a central recess for the passage of the shaft 1 and receives the bearing block 21 of the flange stop 18 and receives it with a spoke 40. Since the shaft 1 not only causes the hanging object to rotate, but also carries it, the weight of the object must be absorbed by the shaft 1 and introduced into the frame 20. For this purpose, a clamping ring 23 is provided above the flange 18, which is clamped on the shaft 1 by means of a clamping screw. The downward axial force is introduced into the flange bearing 18 by means of this clamping ring 23 and from the flange bearing 18 via the plate 22 into the frame 20.

A ring-like element 2 is provided on the frame 20 and is provided with a raceway 4 in the outer region. This element 2 has a spoke 20 leading to the center. The shaft 1 protrudes upward from the flange bearing 18 and accommodates a solar module 19 on the upper end face which supplies the drive of the device with current. Above the flange stop 18, the shaft has a bore for receiving a pin 17, on which an arm 6 is pivotably mounted. This arm 6 carries the motor 7 with gear and a friction wheel 3, which runs on the track 4. Furthermore, a battery (not shown) for buffering the solar module 19 is provided on the arm 6.

Due to the weight of the motor 7 and the battery, which is expediently provided on the side of the arm 6 on which the motor 7 is also arranged, the friction wheel 3 is pressed onto the raceway 4 with a certain force. To increase the contact pressure, a tension spring 8 is provided in this embodiment, which is articulated on the side of the arm 6 opposite the motor 7, in the illustration to the right of the shaft 1, and the solar module 19 and therefore follows the left side of the arm 6 applies a downward moment to arm 6. However, this tension spring 8 is not required in most embodiments. The solar module 19 supplies current to the battery which is connected to the motor 7. The motor 7 can be put into operation via a switch (not shown). The contact pressure between the friction wheel 3 and the raceway 4 is dimensioned such that the friction wheel 3 initially slips when the motor 7 is started up. Due to the sliding friction between the friction wheel 3 and the raceway 4, the friction wheel 3 will nevertheless move on the raceway 4 and thus set the arm 6 and thus also the shaft 1 in motion. With increasing speed, the slip between the friction wheel 3 and the raceway 4 decreases and a transition from sliding friction to rolling friction takes place. The rotating unit with the shaft 1 and the attached object is further accelerated until the friction wheel 3 rolls on the raceway 4 without slipping.

If intervention is made from outside and the object is stopped or slowed down, this leads to a transition from rolling friction to sliding friction on the friction wheel 3. If the object and thus the shaft 1 are stopped completely, the friction wheel simply slips completely, whereby the motor 7 can continue to run unimpeded . As soon as the rotating unit is released, it will accelerate again as when starting until the friction wheel no longer slips.

FIG. 4 describes a similar exemplary embodiment, in which the motor 7 also runs with a friction wheel 3 on a fixed track 4. In this exemplary embodiment, however, it is a standing unit, in which the object to be rotated is not suspended, but is instead provided on a standing shaft 1, which also carries the solar module 19 on its upper end face. The shaft 1 is fixedly connected on the lower end face to a sleeve 23 which is rotatably mounted on an axis 25 by means of bearings 24. The axis 25 is fixedly connected to a tripod 26, which has at least three adjusting screws 27 distributed over the circumference, which support the tripod 26 against the ground or foundation. By means of these adjusting screws 27, the device can be aligned so that the shaft 1 is exactly vertical. A spirit level can be used for this. However, an adjustment aid can also be provided on the tripod 26.

In order to achieve the rotation of the shaft 1, the sleeve 23 is connected via a joint 5 to an arm 6 which, as in the exemplary embodiment described above, carries the drive unit with motor 7 and friction wheel 3. The joint 5 transmits the rotational movement of the arm 6 around the vertical to the sleeve 23, but allows the arm 6 to pivot about the illustrated joint axis in order to apply the required pressure of the friction wheel 3 to the raceway 4 of the tripod 26 due to the weight of the drive unit enable. The operation of this embodiment corresponds to that of the embodiment described above.

Figure 5 describes another embodiment. In this embodiment, the drive unit is stationary and the raceway 4 of the friction wheel 3 is set in rotation and transmits this rotation to the shaft 1. The device is anchored by means of a ground sleeve 29. The ground sleeve 29 is inserted into the ground and, if necessary, firmly anchored by a foundation. A receptacle 30 is inserted into the ground sleeve 29, which has a bearing 32 on its base for mounting the lower end face of the axis 25. The axis 25 is in the receptacle 30 and can be aligned vertically by adjusting screws 27. For this are three adjusting screws 27 distributed over the circumference are provided.

Above the adjusting screws 27, a receptacle 31 for receiving the arm 6 and a battery holder, not shown, is fixedly attached to the axis 25. Above this receptacle 31, a first bearing 24 is provided on the axis 25 and a second bearing 24 is provided on a shoulder in the upper region of the axis 25. The shaft 1 is supported by means of these bearings 24. This shaft 1 is connected in a rotationally fixed manner to a pot-like element 28, which is welded to the sleeve 37, via a sleeve 37 and a knurled screw 38 producing a positive connection between the shaft 1 and sleeve 37.

The arm 6 is rotatably mounted on the receptacle 31 by means of a joint 5 and is pivoted by means of a tension spring 8. The joint 5 is provided at a distance from the axis 25. The tension spring 8 engages on the one hand at the end of the arm 6 and on the other hand at a fastening point which is spaced apart from the joint 5 in order to apply a torque to the arm 6 via the tensile force.

In this way, a certain contact pressure is produced between the friction wheel 3 of the drive unit and the inner wall of the pot-like element 28.

If the motor 7 is started, the friction wheel 3 sets the pot-like element 28 in rotation and this rotation is transmitted to the shaft 1 via the sleeve 37 and the knurled screw 38. The exemplary embodiment shown is provided for forming a laundry spider. The tube 33 of the clothes dryer is placed on the shaft 1. A frictional connection or a force connection can be provided to transmit the rotation from the shaft 1 to the tube 33. It often acts the pipes of laundry spiders around welded pipes. The weld seam can be used to create a positive connection. For this purpose, the shaft 1 can be provided with longitudinal grooves which come into engagement with the weld seam of the tube.

Figure 7 describes another embodiment in which the drive unit rotates. In a receptacle 30 anchored in the ground, a shaft section 34 is supported by bearings 24. The lower bearing 24 is designed so that it allows pivoting of the shaft portion 34. The upper bearing 24 can be aligned using adjusting screws 27. By means of these adjusting screws 27, the position of the upper bearing 24 within the receptacle 30 can be adjusted so that the shaft section 34 is aligned vertically. Above the upper bearing 24, the shaft section 34 merges into the actual shaft 1. This has a larger cross section and carries on its top a solar module 19 with a battery fed by it.

In the lower area, the shaft 1 is connected in a rotationally fixed manner via the joint 5 to an arm 6 carrying the drive unit. The motor 7 drives the friction wheel 3, which rolls on a track 4, which is part of a disk-like element 39, which is firmly connected to the upper region of the receptacle 30. Due to the weight of the drive unit and the arm 6, due to the pivotable mounting on the shaft 1, a sufficient contact pressure between the friction wheel 3 and the raceway 4 is ensured and the torque is transmitted from the arm 6 to the shaft 1.

FIG. 8 describes a fifth exemplary embodiment in which a tubular motor 47 is used to drive the object. The device is received by a floor support 60 which is anchored in the floor. The bottom bearing 60 has a larger opening in the upper region and a recess 63 in the lower region. Centering ribs 62 are provided in a central region, which extend from the wall of the opening to the recess 63 and reduce the cross section of the opening to the recess 63 .

The base bearing 60 serves to receive the axis 55. This is provided on the underside with a pin 59 which engages in the recess 63 in the assembled state. The centering ribs 62 automatically center the axis 55 during insertion and the pin 59 is guided into the recess 63. The recess 63 and the pin 59 are dimensioned such that the axis 55 can still be pivoted slightly to align the axis 55 even in the inserted state. The lower region of the pin 59 is frustoconical in order to facilitate insertion of the pin 59. The upper region of the pin 59 has a square cross section and engages in the recess 63 with a corresponding square cross section. In this way, the axis 55 is fixed in a rotationally fixed manner.

In the upper area, the floor support 60 is provided with threads into which screws 57 can be screwed. By means of these screws 57 and washers 58, an adjusting washer 61 can be clamped to the base bearing 60, which serves to align the axis 55 in the vertical. The adjusting disk 61 has a bore which corresponds approximately to the diameter of the axis 55. In the non-clamped but already inserted state, the axis 55 can thus be easily aligned vertically, for example by means of a spirit level. After Alignment, the adjusting disk 61 is clamped and the position of the axis 55 fixed in this way.

The axis 55 is further provided with a groove 56, in which a corresponding projection 64 of the adjusting disk 61 engages. This positive locking on the one hand prevents rotation of the axis 55 and on the other hand it is ensured that the axis 55 can only be re-used in a certain position after a single alignment even after removal from the base bearing 60.

The axis 55 carries both the object to be rotated and the drive for rotating this object. The object to be rotated has a hollow shaft 41 which can be received by a bearing provided on the axis 55. In the upper region of the axis 55, a shoulder 76 is provided which receives an upper ball bearing 74a. In the central area of the axis 55, a lower ball bearing 74b is held by an adjusting ring 72. The adjusting ring 72 can be clamped on the axis 55 by means of a clamping screw, not shown. The ball bearings 74 rotatably support a shaft holder 73, which has a shoulder 77. The hollow shaft 41 carrying the object can thus simply be plugged onto the shaft receptacle 73 and is seated on the shoulder 77 in the plugged-on state. The shaft 41 can be firmly connected to the shaft receptacle 73 via fastening means, not shown, or an interference fit can be provided between the shaft 41 and the shaft receptacle 73.

The shaft 41 is driven by a tubular motor 47, which transmits its driving force to the shaft 41 via a slip clutch. The axis 55 is provided in the upper area with a shoulder 78 on which the tubular motor 47 is seated, with a central pin of the axis 55 the tubular motor 47 fixed. The tubular motor 47 has a shaft 75 projecting upwards, onto which a sleeve-like element 69 can be attached, which is provided with a threaded rod 70. The transmission of the drive force from the shaft 75 to the element 69 takes place via a clamping screw 68 (not shown in more detail), by means of which a non-positive connection between the shaft 75 and the element 69 is produced.

The threaded rod 70 is flattened on two opposite sides and receives two friction disks 43, which have a corresponding bore, so that the torque of the threaded rod 70 is transmitted to the friction disks 43 via the flats. Friction linings 45 are provided on the upper side of the lower friction disk 43b and the underside of the upper friction disk 43a. Between the friction disks 43, a transmission element 44 is provided, which has a U-shaped cross-section with upstanding legs. In one modification, the friction linings 45 are not applied to the friction disks 43, but to the top and bottom of the transmission element 44.

In order to transmit the drive force from the threaded rod 70 to the transmission element 44 via the friction disks 43, a pressure force is generated between the friction disks 43 and the transmission element 44 by means of a spring 48. The spring 48 is compressed by means of a nut 71, which is screwed onto the threaded rod 70, and presses on the upper friction disk 43a, which is slidably mounted on the threaded rod 70 so that it can be pressed down and between the friction linings 45 and the Transmission element 44 a surface pressure sufficient for transmitting the torque is guaranteed. The transmission element 44 engages with the upwardly directed legs with a connecting element 46 which has recesses for receiving the legs. If the shaft 41 is plugged on, the connecting element 46 is connected to the shaft 41 by means of only indicated screws 79 in order to ensure transmission of the torque from the connecting element 46 to the shaft 41.

By prestressing the spring 48, the maximum torque that can be transmitted by the friction clutch can be set. The shaft 41 can therefore be stopped by a person with suitable adjustment or can be rotated independently of the engine rotation without any problems. This is desirable in numerous applications, for example as a rotatable clothes dryer, and may also be necessary from a safety point of view if people can come into the rotating area of the object in order to be able to exclude injuries from the rotating object.

Since the tubular motor 47 is fixed, the power supply to the motor can be carried out in a simple manner by means of a line via the groove 56 and the adjusting ring 72, which is provided with a cable bushing. The power supply can take place via a solar unit or a power supply unit from the mains.

The entire unit can simply be removed from the base bearing 60 with the axis 55 and reinserted into it.

As with the first embodiment, the described embodiments can intervene and slow down or stop the object at any time without the drive should be switched off or injury could be feared.

FIG. 10 shows an exemplary embodiment in the form of a laundry spider 101, which is used to hold the laundry, is fastened by means of an adapter 103 to a rotatable holder 102, which is driven by an electric motor which cannot be seen from the illustration. The device is started by means of a switch and can be provided with a speed control. The adapter 103 is not only used to attach the clothes dryer 101, but also to change the length of the holder 102.

For this purpose, as can be seen from FIG. 11, several adapters 103 can be hung together. The adapters 103 are provided with a bayonet lock, which is formed by a pin 104 on one part and a corresponding groove 105 on the other part. The bayonet lock can transmit forces in the longitudinal direction of the adapter 103 as well as a torque for rotating the clothes dryer 101. For this purpose, the groove 105 has a sack-shaped end in which the pin 104 comes to rest in the locked state.

The pin 104 is provided on one end of the adapter 103, which is inserted into the opposite end of the other adapter 103. By appropriately dimensioning the diameter, a simple but firm connection can be achieved.

The exemplary embodiment shown in FIG. 11 is driven by a tubular motor which is integrated in the holder 102. This drive will be explained in more detail later with reference to FIG. 9. Figure 12 shows an alternative to changing the effective length of the bracket. According to FIG. 12, a joint parallelogram 106 is provided, with the aid of which, for example, the distance of a rotatable clothes dryer 101 from the ceiling can be adjusted. The bracket 102 shown in FIG. 12, like the brackets 102 described above, has a pin 104 on the outer circumference, which establishes the connection with an adapter 103 or the articulated parallelogram 106.

The head part 107 of the articulated parallelogram 106 is plugged onto the lower end having the pin 104 and for this purpose has a bore 110, the diameter of which is slightly larger than the diameter of the lower end of the holder 102. The head part 107 is for receiving the pin 104 provided with a groove that corresponds to the groove of the adapter 103. On the head part 107, two rods 108 are articulated opposite one another, the ends of which are in turn connected to two further rods 109 via central joints 111 in order to form the joint parallelogram 106. The lower rods 109 are connected in an articulated manner to the clothes dryer 101 via their joints 111 by their downward ends.

In the lower area of the rods 109, toothed segment disks 112 are provided, only indicated in the drawing, which mesh with one another. A parallel guidance of the laundry receptacle 101 with respect to the ceiling is ensured by these toothed segment disks 112 by ensuring that the rods 108, 109 can only be pivoted in pairs by the same angle.

Due to the weight of the laundry holder 101 and the parallelogram, the laundry holder 101 would always be moved to the lowest position. To avoid this, a Weight relief provided by means of a tension spring 113 which is connected to the clothes dryer 101 and the holder 102 and exerts an upward pulling force on the clothes dryer 101. By means of a locking handle (not shown), at least one of the central joints 111 can be fixed and thus the joint parallelogram 106 can be blocked in one position and the clothes dryer 101 fixed in a position that maintains it even when it is loaded.

The clothes dryer 101 can be lowered slightly for loading and the device can easily be brought into the uppermost position, for example when not in use, in which the device least disturbs.

FIG. 13 shows a further exemplary embodiment, which can also be used, for example, for rotating a laundry spider, in which a device is used which causes the laundry spider to be moved to the lowest position in the idle state and to the top position in operation.

The holder 102 has an outer tube 124 in which a shaft 116 is mounted by means of roller bearings 115. In addition, a drive unit 118 is flanged to the tube 124 in the upper region, which has an electric motor that drives a first gearwheel 119 which engages with a second gearwheel 120 which is connected to the shaft 116 in a rotationally fixed manner. The bracket 102 is attached to the ceiling by means of a pot-like element 125 which is firmly connected to the bracket 102 and at the same time covers the drive unit 118.

At the lower end, the shaft 116 is rotatably connected to a spindle nut 117, with which a spindle 121 is acts, which is secured at its upper end by means of a shoulder 126 of larger diameter against falling out of the spindle nut 117, but the inside diameter of the shaft 116 is dimensioned sufficiently large that the spindle 121 can be inserted into the shaft 116. The trapezoidal thread of the spindle 121 is dimensioned so that no self-locking occurs.

At the lower end, the spindle 121 is provided with a fastening element 128 similar to the adapter, which permits the fastening of adapters, a clothes dryer 101 or other receptacles. For this purpose, the lower region of the spindle 121 is provided with a shoulder 123 and the end of the spindle 121 with a holding device for holding a disk 127, the diameter of which is larger than the diameter of the spindle 121 in the lower region reduced by the shoulder.

In the arrangement shown in FIG. 4, a compression spring 148, a transmission element 144, two friction disks 143 and friction linings 145 are provided between the disk 127 and the shoulder 123 and are pressed against one another by spring force. The friction disks 143 are non-rotatably connected to the lower region of the spindle 121 and, via the friction linings 145, transmit a rotational force acting on the spindle 121 to the transmission element 144. The rotationally fixed connection of the lower region of the spindle 121 to the friction disks 143 takes place via a positive connection which by lateral flattening of the lower region and a corresponding bore of the friction disks 143. The transmission element is firmly connected to the fastening element 128, to which the clothes dryer 101 can be connected in the manner described by means of a bayonet catch. If the motor of the drive unit 118 is started, the shaft 116 and the spindle 121 are rotated with it via the spindle nut 117. If the laundry spider 101 is provided with laundry, the inertia and the air resistance, which counteracts a rotation of the laundry spider 101, result in a rotational resistance, which causes the spindle 121 to be screwed into the spindle nut 117 and the shaft 116 first, because of this resistance to be overcome is lower.

If the spindle 121 is screwed in completely, the rotation of the shaft 116 or the spindle 121 is completely converted into a rotation of the clothes dryer 101, with slow starting being ensured by the friction clutch. It is also ensured that the clothes dryer 101 can be stopped at any time by a person against the torque of the drive unit 118.

FIGS. 14 and 15 describe a further exemplary embodiment. In this exemplary embodiment, the drive unit is stationary and the raceway 204 of the friction wheel 203 is set in rotation and transmits this rotation to the shaft 1. The device is fastened to the ceiling by means of a fixed axis 225. A receptacle 231 for receiving the arm 206 is fixedly attached to the axis 225. Above this receptacle 231, a first bearing 224 is provided on the axis 225 and a second bearing 224 is provided on a shoulder in the upper region of the axis 225. The shaft 201 is supported by means of these bearings 224. This shaft 201 is rotatably connected via a sleeve 237 and a knurled screw 238 producing a positive connection between shaft 201 and sleeve 237 to a pot-like element 228 which is welded to the sleeve 237. The arm 206 is rotatably mounted on the receptacle 231 by means of a joint 205 and is pivoted by means of a tension spring 208. The hinge 205 is spaced from the axis 225. The tension spring 208 engages on the one hand at the end of the arm 206 and on the other hand at an attachment point which is spaced apart from the joint 205 in order to apply a torque to the arm 206 via the tensile force.

In this way, a certain contact pressure is produced between the friction wheel 203 of the drive unit and the inner wall of the pot-like element 228.

When the motor 207 is started, the friction wheel 203 rotates the pot-like element 228 and this rotation is transmitted to the shaft 201 via the sleeve 237 and the knurled screw 238. The exemplary embodiment shown is provided for rotating a clothes dryer. The tube 233 is provided in its lower region, not shown, with a pin for connecting an adapter or another device for changing the effective length of the holder.

FIG. 16 describes a drive unit in which a tubular motor 247 is used. The fixed axis 255 is, as in the embodiment shown in Figure 14, attached to the ceiling. The axis 255 carries the tubular motor 247 and also serves to support a hollow shaft 241. In the upper area of the axis 255 there is a shoulder 276 which receives a ball bearing 274a which, together with at least one other bearing (not shown), supports the bearing of the hollow shaft 241 takes over.

The shaft 241 is driven by a tubular motor 247, which is driven by a slip clutch on the Transmits wave 241. The axis 255 is provided in the upper area with a shoulder 278 on which the tubular motor 247 is seated, a central pin of the axis 255 fixing the tubular motor 247. The tubular motor 247 has a shaft 275 projecting downward, onto which a sleeve-like element 269 can be attached, which is provided with a threaded rod 270. The transmission of the drive force from the shaft 275 to the element 269 takes place via a clamping screw 268 (not shown in more detail), by means of which a non-positive connection between the shaft 275 and the element 269 is established.

The threaded rod 270 is flattened on two opposite sides and receives two friction disks 243, which have a corresponding bore, so that the torque of the threaded rod 270 is transmitted to the friction disks 243 via the flats. Friction linings 245 are provided on the upper side of the lower friction disk 243b and the underside of the upper friction disk 243a. A transmission element 244 is provided between the friction disks 243, which has a U-shaped cross-section with upstanding legs. In one modification, the friction linings 245 are not applied to the friction disks 243, but to the top and bottom of the transmission element 244.

In order to transmit the drive force from the threaded rod 270 to the transmission element 244 via the friction disks 243, a pressure force between the friction disks 243 and the transmission element 244 is generated by means of a spring 248. The spring 248 is compressed by means of a nut 271, which is screwed onto the threaded rod 270, and presses on the upper friction disk 243a, which is slidably mounted on the threaded rod 270, so that it can be pressed down and between the friction linings 245 and the transmission element 244 is guaranteed a surface pressure sufficient to transmit the torque.

The transmission element 244 engages with the downwardly directed legs with a connecting element 246, which has recesses for receiving the legs. If the shaft 241 is plugged on, the connecting element 246 is connected to the shaft 241 via only indicated screws 279 in order to ensure a transmission of the torque from the connecting element 246 to the shaft 241.

By prestressing the spring 248, the maximum torque that can be transmitted by the friction clutch can be set. The shaft 241 can therefore be stopped by a person without any problems with a suitable setting or can be rotated further regardless of the motor rotation. This is desirable in numerous applications, for example as a rotatable clothes dryer, and may also be necessary from a safety point of view if people can come into the rotating area of the object in order to be able to exclude injuries from the rotating object.

Figure 17 shows a further embodiment of the invention. In this device, a rotation of objects or a laundry spider is not achieved, but this is pivoted back and forth, which can likewise achieve a considerable reduction in the drying time.

This embodiment is also a device to be mounted on a ceiling, but the device can easily be modified so that it can be mounted on a wall. The clothes dryer 101 has a rectangular shape and has a fastening element 130 in its central region, on which two arms 131 are articulated parallel to one another. The other end of these arms 131 is also articulated on a mounting part 133, which is used to mount the device on the ceiling. The device is driven by a drive unit 118 which has a motor which drives a disk 134 with an eccentrically provided pin 135. One end of a connecting rod 134 is mounted on this pin 135, the other end of which is articulated on one of the arms 131.

If the disk 132 is rotated by means of the motor, the connecting rod 132 swings the arms 131 back and forth, the pivoting movement being transmitted from the arm 131 directly driven by the connecting rod 132 via the fastening element 130 to the other arm 131. Like the drive units 118 described above, the drive unit 118 is provided with a slip clutch (not shown).

The clothes dryer 101 can be conveniently loaded when it is brought into the lowest position. When not in use, the device can be pivoted to the maximum, whereby the clothes dryer 101 is brought close to the ceiling and thus does not interfere with the use of the room.

If the device is to be mounted on the wall, the clothes dryer 101 only has to be mounted rotated by 90 ° so that it is still horizontal. The length of the arms 131 must of course then be sufficient to ensure that the clothes dryer 101 can be pivoted without bumping against the wall. Around the device when not in use, including the clothesline To save 101 on the wall in a space-saving manner, the fastening element 130 can be provided with a joint which can be locked at least in the operating position, which allows the clothes dryer 101 to be folded vertically when not in use and close to the wall with arms 131 swiveled to the side at most to store.

As in the first embodiment, the user can intervene and slow down or stop the object at any time without the drive having to be switched off or injuries to be feared.
