Definitions

  • the invention relates to a clothes dryer with a vertical mast, a spreader frame for holding a clothesline and a locking device for locking the spreader frame in a closed position, the spreader frame having a plurality of arms and a plurality of spreader arms for supporting the arms, the arms in a lower collar that can be moved along the mast and is pivotably mounted about pivot axes and the spreading arms are articulated on an upper collar fixed to the mast and on the arms in articulation axes.
  • a wide variety of forms of laundry drying racks are known from the prior art.
  • a subcategory is, for example, rotary clothes dryers that can be folded up and down, which are sometimes also referred to as laundry umbrellas.
  • a laundry umbrella with a plurality of foldable arms is in the DE 10 2004 030 720 B4 shown and described. The arms are used to stretch out a clothesline on which clothes and textiles can be hung up to dry.
  • a rotary clothes dryer which has an expansion frame for carrying a clothesline.
  • a clamping device is provided to open the expansion frame and hold it in the open position. Its operation is carried out by the operator Rotary clothes dryer requires practice and skill.
  • a pivoting and spring-loaded locking hook is provided in order to keep the expansion frame in the closed position outside of use times. The storage of the locking hook is viewed as complex and susceptible to wear.
  • the object of the present invention is to create a rotary clothes dryer which can be opened easily and kept securely in the closed state and which at least partially eliminates the disadvantages of the prior art.
  • the rotary clothes dryer has a vertical mast, a spreader frame that can be opened and closed to hold a clothesline and a locking device for locking the spreader frame in a closed position, the spreader frame having a plurality of arms for stretching, i.e. carrying the clothesline, and a plurality of spreader arms to support the arms, with each arm being assigned a spreader arm.
  • the arms are mounted so that they can pivot about pivot axes in a lower collar that can be moved along the mast.
  • the spreader arms are attached to an upper collar fixed to the mast and are articulated in articulation axes on the arms.
  • the articulation axes on the arms are located between the lower ones and the free upper end of the arms.
  • the articulation axes on the upper collar form upper articulation axes and the articulation axes on the arms form lower articulation axes of the spreader arms.
  • the pivot points of the articulation axes of the spreading arms in the arms are radially further apart from a vertical central axis of the mast than the pivot points of the pivot axes in the lower collar and than the pivot points of the articulation axes in the upper collar.
  • the locking device has at least one rigid engagement element attached to the upper collar and a plurality of rigid counter-elements, one counter-element being attached to a respective free end of the arms.
  • the engagement element and counter elements are hooked into one another when the expansion frame is closed.
  • the advantage here is that the engagement element and counter-elements are particularly robust thanks to their rigid design and allow a simple manufacturing and assembly process. Since such a locking device only has the function of locking the arms, it cannot initiate an opening movement of the expansion frame.
  • the rigid design of the locking device can therefore only be implemented in combination with the special arrangement of the pivot points according to the invention. Both aspects together enable the rotary clothes dryer to be set up easily and at the same time easy to use.
  • the engagement element and the counter-elements have locking surfaces which are complementary to one another and which serve for locking and locking.
  • the engagement element is designed to be segmented and each counter-element is assigned a segment of the engagement element. This allows material to be saved.
  • the spreading frame has a displacement device for vertically moving the arms when the spreading frame is closed. This enables the arms to be moved vertically relative to the mast before the spreader frame opens or after it has been closed.
  • the displacement device can be realized by elongated holes formed in the upper collar, in which the articulation axes of the expansion arms are displaceable.
  • the displacement device can be implemented by elongated holes formed in each arm, in which the articulation axes of the expansion arms are displaceable.
  • each articulation axle is assigned an elongated hole and the articulation axles have bolts guided in the elongated holes.
  • the elongated holes are preferably oriented vertically, so that they only allow freedom of movement of the arms in the vertical direction.
  • Vertically oriented means that the long sides of the slots are vertical and parallel to the mast. This vertical orientation applies to the elongated holes in the arms as long as the spreader frame is closed.
  • the mast of the rotary clothes dryer can have a vertically movable lid.
  • a cover can prevent the penetration of dry and liquid dirt into the mast and the upper area Prevent collars.
  • the vertical displaceability of the cover means that it is not spaced from the counter elements at the free ends of the arms when the expansion frame is closed and that dirt can also be prevented from penetrating here.
  • the lid When opening or closing the expansion frame, the lid can be briefly lifted by the counter elements.
  • the rotary clothes dryer can additionally have an opening device for unfolding the expansion frame with a pull rope and with an actuating element attached to its free end, for example a handle. By pulling on the actuating element, the lower collar can be moved along the mast towards the upper end of the mast.
  • Fig. 4 shows a view of the complete clothes dryer in the form of a clothes dryer 100.
  • the clothes dryer 100 stands on the floor 1000 and can be opened and closed, i.e. folded up and down.
  • the tumble dryer is shown in the open state, in which a clothesline 1 is stretched.
  • the clothesline 1 is supported by one
  • a plurality of arms 11 are held, which are pivotally attached to a mast 20.
  • an opening device 30 can be provided.
  • an actuating element 31 for example a handle
  • an operator can pull a pull rope 32, which is guided over pulleys on the arm, on the lower collar and on the mast.
  • the pull on the actuating element 31 causes the pull rope 32 to lift the lower collar 32 along the mast 20, whereby the rotary clothes dryer 100 is moved from its closed to the open state shown.
  • Fig. 1a shows a view of the rotary clothes dryer 100 in the closed state.
  • the clothes dryer 100 has a vertical mast 20, an expansion frame 10 for holding a clothesline 1 (not visible).
  • the expansion frame 10 has a plurality of arms 11 and a plurality of expansion arms 12 for supporting the arms 11.
  • Each arm 11 is assigned an expansion arm 12.
  • the arms 11 are pivotally mounted about pivot axes 7 in a lower collar 13 which can be moved along the mast 20.
  • the spreading arms 12 are articulated on the one hand on an upper collar 14 fixed to the mast 20 in articulation axes 8 and on the other hand on the arms 11 in articulation axes 6.
  • the mast 20 has a vertically movable cover 22 at its upper end as a kind of roof.
  • Fig. 1b shows a true-to-scale representation of the position of the pivot points of the rotary clothes dryer Fig. 1a , in which their position relative to each other can be seen.
  • the pivot points of the articulation axes 6 of the spreading arms 12 in the arms 11 are radially further apart from a vertical central axis 21 of the mast 20 than the pivot points 7 of the pivot axes in the lower collar 13 and than the pivot points 8 of the articulation axes in the upper collar 14.
  • the distance A6 of the pivot point 6 from the central axis 21 of the mast 20 is greater than the distance A7 and greater than the distance A8 of the other two pivot points 7 and 8.
  • Fig. 2 shows the upper area of the mast 20 of the rotary clothes dryer 100 in the closed state.
  • a locking device 2 is provided with a rigid engagement element 3 attached to the upper collar 14.
  • Part of the locking device 2 is also a plurality of rigid counter-elements 4 attached to a respective free end of the arms 11.
  • the engagement element 3 is designed to be segmented and each counter-element 4 is assigned a segment.
  • the engagement element 3 and counter-elements 4 are hooked into one another and thus hold the arms 11 in their position, thus preventing the expansion frame 10 from unfolding.
  • the engagement element 3 and the counter-elements 4 point in a complementary manner mutually shaped locking surfaces 5.
  • the expansion frame 10 also has a displacement device 9 for vertically displacing the arms 11 in the closed state of the expansion frame 10.
  • the displacement device 9 is realized by elongated holes 9.1 formed in the upper collar 14, in which the articulation axes 8 of the expansion arms 12 are realized by means of bolts 9.2 stored and movable.
  • the elongated holes 9.1 are vertically oriented.
  • the arms 11 are also moved vertically upwards a small distance, as far as the 9:1 slots allow.
  • a respective bolt 9.2 has arrived at the upper end of a respective elongated hole 9.1 (not shown)
  • the arms 11 can no longer be moved vertically upwards and the locking is released by the locking device 2.
  • the locking surfaces 5 come out of engagement.
  • the lower end of the arms 11 can then be moved further upwards with the lower collar 13, while the upper free end of the arms 11 pivots radially outwards and the expansion frame 10 unfolds with its arms 11.
  • the counter elements 4 push the vertically movable cover 22 of the mast 20 slightly upwards. As soon as the counter elements 4 are located radially outside the circumference of the cover 22 due to the unfolding movement, the cover 22 is lowered again.
  • Fig. 3 shows the upper area of the rotary clothes dryer 100 in the open state.
  • the connection of the spreading arms 12 to the upper collar 14 via the articulation axles 8 can be seen in the cutout.
  • the segmented engagement element 3 is integrated into the upper collar 14.
