Description

Rotary clothes hanger

Technical Field

The invention relates to the technical field of rotary clothes hangers with supporting arms. The support arm is arranged on the sliding sleeve in an articulated manner. The sliding sleeve is repositionable along the mast and is selectively movable to an inoperative position and a deployed position. The mast is provided with a first latching means for the sliding sleeve to snap into in the deployed position. The sliding sleeve is provided with second latching means for latching. The second latching means comprises at least one pawl for deploying the support arm. The pawl automatically locks into the first latching means to prevent the sliding sleeve from automatically moving from the extended position into the rest position.

Background

In known rotary drying stands of this type, for example in EP 2354297B 1, the sliding sleeve in the rotary drying stand has a pulling cable arranged thereon, which is arranged to the sliding sleeve via a pulley arrangement arranged to the mast and to the sliding sleeve. To deploy the support arm, tension is applied to the cable to move the sliding sleeve relative to the mast, moving the support arm from the inoperative position to the deployed position. The pawl is continuously latched in the first latching device during deployment, thereby preventing the sliding sleeve from automatically moving from the deployed position to the inoperative position when no tension is applied to the cable.

At least one line is arranged between the support arms such that in the extended position of the support arms a plurality of lines arranged parallel to each other extend over the length of the support arms.

A problem with prior art rotary drying stands is that the arrangement of mast, sliding sleeve, pulley arrangement and guy cable is usually very stiff or becomes increasingly stiff over time due to wear and contamination of the parts involved. This means that a high pulling force is required to move the support arm from the rest position to the extended position. Another disadvantage is that to obtain the maximum line tension, the maximum pulling force must be applied at the furthest distance from the mast. This is disadvantageous from a safety point of view as well as from an ergonomic point of view.

In addition to the above-described rotary laundry stands, there are also rotary laundry stands which do not have a pull cord for opening. With this, however, the sliding sleeve with the support arm on the mast must be pushed vertically upwards by hand. The increase in height and line tension causes an increase in workload and is ergonomically disadvantageous.

Disclosure of Invention

The aim of the invention is to provide a rotary drying rack, the supporting arm of which can be moved from the inoperative position to the extended position with little force. Furthermore, the rotary drying rack enables the threads to be tightened in a simple and easy manner.

The invention achieves the object with the features of claim 1. The dependent claims refer to preferred embodiments.

To achieve the object of the invention, the sliding sleeve is provided with a ratchet rod. The ratchet lever is provided on the slide sleeve so as to be rotatable (tiltable) between a releasing position (rest position) and an operating position (operating position). The ratchet rod has a grip portion and a protrusion. When the ratchet lever is moved to the operating position, the protrusion is latched in the first latch device. The detent prevents rearward movement of the sliding sleeve when the sliding sleeve is moved from the rest position to the deployed position. The pawl is latched in the first latching device in such a way that the sliding sleeve can be gradually moved from the inoperative position to the extended position, without the sliding sleeve being able to be automatically moved from the extended position to the inoperative position. In the process that the ratchet rod moves from the non-working position to the operating position, the ratchet rod is locked in the first locking device, and the rotary clothes hanger is unfolded by the ratchet rod. Once the ratchet rod is latched in the first latching arrangement, the sliding sleeve moves toward the deployed position as the ratchet rod moves further toward the operating position. The ratchet rod thus forms a crawling device or crawling assistance device, which moves the sliding sleeve along the mast from the inoperative position to the deployed position. When the ratchet lever is moved from the operating position to the rest position, the pawl latches in the first latching means to prevent movement of the sliding sleeve in the opposite direction. By repeatedly moving the ratchet lever between the inoperative position and the operative position, the rotary drying rack is unfolded and the support arm is moved in the direction of the unfolded position. Thus, the sliding sleeve climbs up the mast, and the rotary drying rack is gradually unfolded. Movement of the ratchet rod corresponds to movement of the ratchet.

The pawl may be provided with a locking bar. By means of the locking lever, the pawl can be actuated and spaced apart from the first latching means. This allows the sliding sleeve to be moved from the deployed position to the inoperative position.

The pawl may be provided with a resilient member which automatically pushes the pawl into the first latching means. This prevents the pawl from being accidentally disengaged from the first latching means so that the sliding sleeve is automatically moved from the deployed position to the inoperative position.

The locking lever may be provided with a pusher portion. Wherein when the pusher portion is actuated, the pawl is spaced from the first latching device such that the sliding sleeve moves from the deployed position to the inoperative position. The locking lever is preferably hinged to the sliding sleeve. The pusher portion is preferably formed at a free end of the locking lever opposite the pawl. When pressure is applied to the pusher section, the pawl moves out of the first latch means and the sliding sleeve can be moved from the deployed position to the inoperative position.

The first latching means may be in the form of a rack. In embodiments, the sliding sleeve can be fixed at various positions along the mast. Furthermore, the detent of the sliding sleeve can be locked into the first latching device at an early stage, so that the unfolding of the support arm up to the maximum line tension can be achieved further with particularly little force.

The ratchet rod may be mounted to the sliding sleeve by rotating the rod. The ratchet rod preferably performs a circular motion about its hinged connection during movement between the rest position and the operative position. To prevent the ratchet rod from getting stuck in the first latching device in a circular motion, the ratchet rod may be attached to the sliding sleeve by a rotating rod. One end of the rotating rod is hinged on the sliding sleeve. The ratchet rod is hinged to the other end of the rotating rod. The rotating lever can be unscrewed when the ratchet lever moves between the rest position and the operating position, thereby spacing the ratchet lever from the sliding sleeve so that the ratchet lever does not become jammed in the first latch device.

The ratchet rod may be provided with a second resilient member which automatically moves the ratchet rod to the rest position. This ensures that the ratchet rod is spaced from the first latch means when the deployment of the rotary laundry rack is complete. In this case, the second elastic member is preferably disposed between the ratchet lever and the rotating lever.

A handle may be provided on the sliding sleeve. This makes the sliding sleeve particularly ergonomically operable.

The support arm may be provided with at least one line. Preferably, the wire is arranged between the support arms in such a way that a plurality of wire segments arranged parallel to each other are stretched in the unfolded position. The wire or set of wires is tensioned when the support arm is moved from the rest position to the deployed position. The sliding sleeve may be positioned in such a way that the thread or the arrangement of threads has a desired tension.

Detailed Description

Fig. 1 and 2 show a rotary laundry rack 1 with a support arm 2. The support arm 2 is arranged hingedly on a sliding sleeve 4, which sliding sleeve 4 can be repositioned along the mast 3. The wire 17 is provided to the support arm 2. Wherein the wire 17 is arranged in such a way as to be fixed to the support arm 2, so that a plurality of wire segments arranged parallel to each other results. The support arm 2 can be selectively moved into an inoperative position (fig. 2) and into a deployed position (fig. 1).

Fig. 3 to 6 show the sliding sleeve 4 arranged on the mast 3 in detail. A first latching device 5 is provided on the mast 3, in which first latching device 5 the sliding sleeve 4 latches in the deployed position. The first latching device 5 is designed as a toothed rack. For this purpose, the mast 3 has a recess which accommodates a first latching means 5 in the form of a toothed rack.

A second latching device 6 is provided on the sliding sleeve 4 for latching in the first latching device 5. The second latching device 6 has a pawl 7 for extending the support arm 2. The pawl 7 is automatically latched in the first latching means 5, thereby preventing the sliding sleeve 4 from automatically moving from the extended position to the inactive position.

A ratchet rod 8 is hingedly arranged to the sliding sleeve 4. The ratchet lever 8 is provided on the slide sleeve 4 so as to be tiltable between a rest position and an operating position. The ratchet lever 8 has a grip 9 and a projection 10. When the ratchet lever 8 is moved to the operative position, the protrusion 10 latches in the first latching means 5.

The ratchet rod 8 is attached to the sliding sleeve 4 via a rotating rod 14. The second elastic member 15 is provided to the ratchet lever 8. The second elastic element 15 automatically moves the ratchet rod 8 to the rest position. The second elastic member 15 is disposed between the ratchet lever 8 and the rotating lever 14.

The movement from the inoperative position to the operative position effects the deployment of the rotary drying rack 1 by the ratchet lever 8 being latched in the first latching device 5. Once the ratchet rod 8 is latched in the first latching means 5, the sliding sleeve 4 is moved towards the deployed position when the ratchet rod 8 is moved further towards the operating position. The ratchet rod 8 thus forms a crawling assistance device, and the sliding sleeve 4 is moved along the mast 3 from the inoperative position to the deployed position by means of the line assistance device.

When the ratchet lever 8 is moved from the operating position to the rest position, the pawl 7 is automatically latched in the first latching means 5, preventing the sliding sleeve 4 from moving in the opposite direction. By repeatedly moving the ratchet lever 8 between the inoperative position and the operative position, the rotary drying rack 1 is unfolded and the support arm 2 is moved in the direction of the unfolded position. The sliding sleeve 4 thus climbs up the mast 3, gradually deploying the rotary drying rack 1. The movement of the ratchet lever 8 corresponds to the movement of the ratchet.

The locking lever 11 is provided to the pawl 7. Furthermore, a first elastic element 12 is provided on the pawl 7, which automatically presses the pawl 7 into the first latching means 5.

The locking lever 11 has a pusher portion 13. When the pusher portion 13 is actuated, the pawl 7 is spaced from the first latching means 5, so that the sliding sleeve 4 can be moved from the deployed position to the inactive position. The locking lever 11 is hinged to the sliding sleeve 4. The pusher portion 13 is formed by a free end of the lock lever 11 opposite to the pawl 7. When pressure is applied to the pusher portion 13, the pawl 7 is spaced from the first latching means 5 and allows the sliding sleeve 4 to move from the deployed position to the inoperative position.

In the present embodiment, the slide sleeve 4 has a grip 16 formed on the outer peripheral side thereof.

Referring to fig. 3, the pawl 7 of the second latching device 6 latches in the first latching device 5 and, in the illustration, the sliding sleeve 4 is locked in the deployed position. The ratchet rod 8 is located on the sliding sleeve 4 and is in the rest position.

Referring to fig. 4, ratchet rod 8 extends from sliding sleeve 4 and is in the operating position. During the movement of the ratchet lever 8 from the rest position to the operating position, the projection 10 of the ratchet lever 8 latches in the first latching means 5 of the mast 3 and, as the ratchet lever 8 is further actuated, the sliding sleeve 4 moves along the mast 3 towards the deployed position.

Referring to fig. 5, the pusher portion 13 of the locking lever 11 is actuated so that the pawl 7 is spaced from the first latching means 5 and the sliding sleeve 4 can be moved from the deployed position to the inoperative position.

Fig. 6 shows the sliding sleeve 4 described above. For better illustration, the second latching device 6 and the ratchet rod 8 are not shown.

Fig. 7 shows in detail the second latching device 6 with the locking lever 11 and the ratchet lever 8 with the projection 10.
