Description

30th

The invention relates to a ventilation and drying rack according to the preamble of the claim 1.

These so-called laundry umbrellas, as described, for example, by DE-AS 12 04 616 and CH-PS 3 90 863 known are very popular as ventilation and drying devices for clothing. It is with them possible to hang a large amount of clothes and laundry in a small space. So are clothesline lengths of 70 m not uncommon. These devices can be folded up when not in use and be stored in a small space. The disadvantage of these devices is that they are hanging around in a disorderly manner the clothesline when folded. The clothesline can get tangled and is easy exposed to heavy pollution.

In the older DE-OS 31 33 092 a generic Device proposed in which a tension element in the form of spring elements in each of the arms runs, which is connected on the one hand with the respective rope corners, on the other hand with a fixed point in the center is. The disadvantage of this device is that several springs are required, the assembly very much is difficult and in the final phase of opening the necessary forces are constantly increasing.

The object of the invention is to design the clothesline retraction in a generic device in such a way that that this process with as little effort as possible without cumbersome manipulations and without additional spring elements in the arms of the spreading frame, which simplifies assembly, are possible will.

This object is achieved by the characterizing features of claim 1.

Due to the geometry of the spreader frame and the rope corner, the movement sequences, line pulling, movement of the arm end to the mast and downward movement of the fastening star when folding is not parallel-linear. This means that the individual points cover different distances per unit of time. Those differences help in addition to the leash, the storage of the sliding ring with the interposition of a Balance spring. At the same time, the spring reduces the tensile force in the final phase of the opening movement on the pull rope.

The transition phase of the arms from being flush with the mast is a particular difficulty with the current laundry umbrellas when they are opened low spread position.

This transition cannot be made with the usual elevator rope alone; every single one has to do it Arm can be pulled slightly outwards to overcome the dead center. This is with the invention Formation of the sliding ring with expansion bevels that interact with counter bevels on the support struts, not necessary anymore. By pulling on the pull rope, the sliding ring is against the counter bevels on the Support struts pushed and pushes them outwards, so that the dead center is overcome and the opening process can be accomplished solely by the pull rope. Supported by the tension spring, only minimal forces are required.

Some exemplary embodiments of the invention are explained in more detail below with reference to the drawings. It shows

Fig I is a perspective view of a ventilation and drying rack in use position,

F i g. 2 a ventilation and drying rack distorted to scale, with the left side in an approximate position of use and the right side is shown at the moment of opening and

F i g. 3 the principle of the loop tape in a plan view of an arm with indicated rope corners.

On a mast 1, a fastening star 2 is displaceable but lockable with respect to a fixed point 3 stored. On this fastening star 2, arms 4, between which rope corners 5 are stretched, can be pivoted stored; they are additionally supported against the fixed point 3 via spreader arms 6. The individual rope corners 5 are each articulated to a tension element 7 inside the arms 4. The tension elements 7 are made up of the arms 4 led out and connected to an actuating device in the form of a sliding ring 8. The sliding ring 8 is supported on fixed point 3 with the interposition of a spring 9.

To open the spreading frame 10, it consists of the arms 4 and the spreading arms 6, is on the sliding ring 8 a pull rope 11 attached, which is from the sliding ring 8 via a Deflection 12 in the fastening star 2, another deflection 13 in the fixed point 3 runs back to the fastening star 2. For this is an actuation end 14 led out.

In Fig. 2, the spreading frame 10 is shown in the right half in an approximately closed position. At the Train on the actuating end 14 of the pull cable U, the sliding ring 8 moves down and slides with his Spreading bevel 15 on the counter bevels 16 on the spreading arms 6. This overcomes the dead center, so that the spreader frame can only be opened by pulling the actuating end 14. A loosening by hand of the individual arms 4 from the folded-in rest position, in which the bearing points of the spreading arms 6 as well as the arm 4 are in one plane, is not necessary.

The sliding ring 8 cooperates via the tension elements 7

the actual device for pulling the Seilccke 5 into the arms 4, as in DE-PS 32 00 013 (parent application) described, together.

In Fig. 3 is a spreader frame schematically with 3 rope corners Excerpts shown in plan view Here, for the sake of simplicity, only 3 rope corners are indicated, the length of which between two adjacent arms 4 are denoted by 51, 52 and 53. Should each the entire length of the clothesline disappears in the arms 4, so when folding the ventilation and drying rack in each arm 4 on both sides 1/2 51, 1/2 52 and 1/2 53 are drawn in. There at Folding the frame of the feed via the tension element 7 is the same length for each rope corner, the must Compensation takes place within the respective arm 4 via the different lengths of the envelope loops 18. The loop length is

-and the loop length

When the frame is folded up, the pulling element 7 is pulled in the direction of the arrow 26. It starts immediately the pull-in of the outermost rope corner, i.e. length 51; only when the remaining clothesline is out of 51 den When the value has reached 52, the first envelope loop 24 begins to turn to the right. As soon as the If the remaining clothesline length from 52 has reached the value 53, the next envelope loop 25 also follows with hers Envelope in order to achieve the constellation according to FIG. 2 right side to reach.

While the line retraction is compensated for the movement of the tension element 7, as described, in the arm 4 the compensation of the difference in movement between the tension element 7 and the fastening star 2 by the spring 9 achieved. When opening the clothes screen, so when transferring from the position shown in the right half in Fig.2, in the position in the left Half of the pivoting path 27 of the tip 28 of the arm 4, that is, the area of the outermost rope corner 51, is greater as the adjustment path of the fastening star 2; the pulling element 7 is increased in accordance with the pivoting path 27 drawn in, so that the path difference is compensated for by tensioning the spring 9. From a certain point on The sliding path of the fastening star 2, depending on the overall geometry of the spreading frame 10, is reversed Path difference by. The pivoting path 27 of the tip 28 only increases a little, the rope corners 5 are almost tense, on the other hand, the mounting star 2 still has to cover a significantly greater distance. The spring 9 relaxes and thus reduces the tensile force at the actuation end 14.
