Identical or functionally equivalent elements are provided with the same reference numerals in all figures.

One in the Fig. 1 to 6 illustrated embodiment of a designated as a whole with 100 frame device is used in particular in a rotary dryer 102 application. The rack device 100 comprises a mast 104 on which a plurality of support arms 106 are pivotally mounted.

The support arms 106 are in particular pivotally mounted on a Tragarmlagerring 108. The Tragarmlagerring 108 is preferably arranged displaceably on the mast 104.

The rack assembly 100 further includes a plurality of support arms 110 which are pivotally connected at one end to the support arms 106 and at another end to a Stützarmlagerring 112.

The Stützarmlagerring 112 is disposed on the mast 104, for example, slidably mounted or fixed. For example, by means of a latching device 114, the Stützarmlagerring 112 is preferably fixed in different positions on the mast 104.

The support arms 106 are actuated by means of an actuating device 116, in particular optionally in a retracted position (see Fig. 1 ) or in an unfolded position (not shown) can be brought.

The support arms 106 are connected to each other in particular with several lines. In the unfolded position of the support arms, the lines are substantially tensioned and thus enable suspension of laundry when the rack device 100 is designed as a clothes dryer 102.

Further, the support arms 106 may also be provided with a cover (not shown), tarpaulins, etc., particularly when the rack apparatus 100 is formed as a screen device (not shown) such as an umbrella or sunshade.

The actuation of the frame device 100 is effected in particular by varying the distance of the support arm bearing ring 108 from the support arm bearing ring 112.

The support arms 110 are thereby brought into an unfolded position, as well as the support arms 106th

In the in Fig. 1 illustrated folded position of the rack device 100, the support arms 106 are positioned by means of a positioning member 118. In particular, the positioning element 118 comprises a plurality of positioning sections 120 for receiving a respective support arm 106.

In this way, in particular a stable recording of the support arms 106 can be achieved in the retracted position.

The positioning element 118 is in particular formed integrally with the support arm bearing ring 112.

The actuating device 116 for actuating the frame device 100 comprises in particular a cable 122, which in particular comprises a cable 124.

By pulling on one end of the cable 124, for example, the support arm bearing ring 108 can be raised and thus moved in the direction of the Stützarmlagerrings 112, to ultimately bring the support arms 106 from the retracted position to the unfolded position.

The cable 124 thus forms in particular an actuating element 126 of the actuating device 116.

Depending on the design of the frame device 100, it may happen that an arm device 128, which in particular includes the support arms 106, the support arms 110, the Tragarmlagerring 108 and the Stützarmlagerring 112, in a retracted position (see Fig. 1 ) and thus impedes actuation by means of the cable 124.

This blocking results in particular from unfavorable angular relationships of the support arms 106 relative to the support arms 110 and / or relative to the mast 104.

To overcome the blockage then usually the support arms 106 are manually pressed by the user with respect to a longitudinal center axis 130 of the mast 104 radially outward until the resulting other angular position of the support arms 106 and the support arms 110 relative to the mast 104 actuation by means of the actuator 116th allows.

In the in the Fig. 1 to 6 illustrated embodiment of the rack device 100, such a manual spreading of the support arms 106 is unnecessary. For this purpose, rather, an ejector 132 for ejecting the support arms 106 from the in Fig. 1 illustrated folded position provided.

In particular, the ejection device 132 comprises an ejection element 134, which is designed as a spreading disc 136, for example.

The ejection element 134 is rotatably mounted relative to the mast 104 at the same. In particular, the ejection element 134 is mounted rotatably about the longitudinal center axis 130 on the support arm bearing ring 112 and / or the positioning element 118.

In particular, the ejection element 134 is movably clamped between a base body 138 of the support arm bearing ring 112 and / or of the positioning element 118 and an annular cover element 140.

The ejection element 134 preferably has a circular opening 142 through which the mast 104 extends.

The ejection element 134 is arranged in particular concentrically with the mast 104 with respect to the longitudinal central axis 130 of the mast 104.

The ejection element 134 preferably comprises a plurality of ejection projections 144, which are distributed along a circumferential direction 146 of the ejection element 134. The ejection protrusions 144 are particularly in the Essentially triangular in shape and have a starting from a minimum outer radius r flat rising edge 148. The flank 148 extends in particular up to a maximum outer radius r (see

Fig. 3 ).

At the in Fig. 3 illustrated release position of the ejection element 134, the ejection element 134 relative to the main body 138 of the Stützarmlagerrings 112 and / or the positioning 118 arranged so that the positioning portions 120 for positioning of the support arms 106 connect to portions of the ejector element 134 with a minimum outer radius r.

The support arms 106 can thus be positioned in the positioning sections 120.

The ejection element 134 is preferably resiliently coupled by means of a spring element 150 with the base body 138, so that the ejection element 134 without an operation thereof due to the resilient action of the spring element 150 always in the in Fig. 3 shown release position is moved.

For actuating the ejection device 132, one end 152 of the cable 124 of the cable pull 122 is preferably fixed to the ejection element 134.

The cable 124 extends from this end 152 at least in sections along the circumferential direction 146 and then substantially parallel to the longitudinal central axis 130.

Due to the section of the cable 124 extending along the circumferential direction 146, a pulling movement on the cable 124 results in a rotating actuation of the ejection element 134.

In particular, the ejection element 134 is made of the in Fig. 3 shown release position in the in Fig. 6 brought shown ejection position. During movement from the release position to the ejection position, the ejection protrusions 144 are moved relative to the positioning portions 120, whereby the flanks 148 of the ejection protrusions 144 engage the support arms 106 and push the support arms 106 radially outward with respect to the longitudinal central axis 130.

In particular Fig. 6 can be seen, the support arms 106 are thereby moved away from each other and thus spread.

The rotational movement of the ejection element 134 thus results, in particular, in ejecting the support arms 106 out of the positioning sections 120.

The further operation of the frame device 100, in particular a further pulling movement on the cable 124 is then not blocked due to an unfavorable orientation of the support arms 106 and / or the support arms 110. Rather, an easy operation of the rack device 100 is always ensured due to the ejector 132.

In alternative embodiments (not shown) of the rack device 100, use thereof may be provided in screen devices, in particular umbrellas or parasols. The support arms 106 are then pivotally fixed, in particular at an upper end of the mast 104. The support arm bearing ring 112 is then preferably slidable along the mast 104 to selectively place the support arms 106 in the deployed position or in the retracted position. Even with such a screen device, the ejector 132 may be advantageous, especially if it is stationary umbrella devices with a large umbrella diameter, which are also operated for example by means of a cable 122 comprehensive actuator 116.
