DE102005020026A1 - Umbrella-like clothes drier has mast with arms holding clothes line moving along sliding star, supported by spreading arms pivotally mounted on holding star, with expanding body and counter body spring-connected to each other - Google Patents

Abstract

The clothes drier comprises a vertical mast on which arms bearing the clothes line can move along a sliding star and are supported by spreading arms. The spreading arms are pivotally mounted on a holding star arranged on the mast by means of holding axes and on the bearing arms by means of articulated axes. The drier has an expanding body mounted on the mast which interacts with at least one spreading arm and/or counter body. The expanding body and counter body are spring-connected to each other by means of a coupling device in its rest position.

Description

The The invention relates to a laundry screen with a vertical mast at which, forming the expansion frame, in one Sliding bearing the clothesline Arms are pivotally mounted by means of support shafts, the spreading arms supported are, on the one hand by means of holding axes in a holding star on the mast and on the other hand pivotable by means of articulation axes on the arms are stored, and a guided by the holding star on the slip joint elevator line and a Aufspreizeinrichtung.

By the EP 0 649 935 B1 was a laundry umbrella with a spreading known, in which on the mast below the holding axes longitudinally displaceable an expansion body is mounted, which cooperates with attached to the spreader arms support elements and pivots the spreader arms from its retracted rest position with a longitudinal displacement. It is necessary to arrange an extensive mechanism in the mast, which is acted upon by the pull rope. In addition, openings in the mast are required, in which engage the support elements. The construction cost is significant.

Next is through the EP 0 898 006 A2 a laundry screen with a spreading known, in which the spreading device has a holding star adjacent, first sleeve which is connected by rod-shaped spreading with a distant from the sliding joint, second sleeve which is displaceable by pulling the pull cable for deflecting the spreading members to the first sleeve , In this embodiment, too, movable parts to be mounted separately are required, which make the production process more expensive and can lead to disruptions, inter alia, due to weather influences.

task The invention is a laundry screen to provide with a spreading device, in which the Aufspreizfunktion With a minimum of construction effort is to realize that absolutely fail-safe is and remains easy to use.

These Task is inventively characterized solved, that the Spreading by at least one storage of the arms or the Spreader arms in an axial guide is formed between the mast and Spreizgestell, wherein the axial guide and / or a guide at an acute angle to the mast.

By the inclined guide is created when moving up of the slip joint by the pull rope a directed away from the mast Force component, so that the Spreading process by overcoming of the death point is initiated. There are no additional ones Components required, also occurs in the closed state of laundry screen a self-locking one. The fact that no moving parts used become, no additional arises Friction, so that the Force required to open of the laundry screen is reduced to a minimum.

Further Embodiments of the invention are the dependent claims remove. So is by training the leadership as a slot guide a special simple production possible.

Around to increase the spread distance is it is advantageous, the slot guides provide both on the pivot axes and on the support and support axes, the slot guides at the Anlenkachsen from inside to outside, the slot guides the support axles and / or the support shafts are directed from the outside inwards. As a result, the force component during Aufspreizvorgang away from the mast significantly enlarged.

In Further embodiment of the invention, the guide is designed as a slanted guide. There are both on the mast, as well as on the support arms or support arms against each other running wedge surfaces provided, which run against each other during the axial lifting of the sliding joint and a force component away from the mast to overcome the dead center in the Cause spreading process.

Finally, can the inclined wedge guide at least one pair of magnets on the mast and a pair of opposite polarity on the support or support arm be formed. This will provide a secure lock at rest and additional assistance with Spreading guaranteed.

Some embodiments The invention will be explained in more detail below with reference to the drawings. It demonstrate:

1 a laundry screen simplified in the folded state, with only the right half is shown,

2 a representation according to 1 in the phase of spreading,

3 an alternative solution according to 1 .

4 a representation according to 3 in the phase of spreading,

5 an alternative solution with inclined wedge guidance,

6 another alternative solution with a helical wedge guide with magnets,

7 Another alternative solution with a Schrkekeilführung and

8th the embodiment according to 7 at the moment of the phase of spreading.

On a mast 1 is a slip joint 2 concerning a holding star 3 slidable but lockable stored. On the slip joint 2 are four arms 4 over swivel axes 5 pivoted. Between the poor 4 is an unillustrated clothesline tense. The poor 4 are via spreader arms 6 against the holding star 3 supported. The spreading arms 6 are by means of articulation axes 7 on the arms 4 and by means of holding axes 8th at the stop star 3 stored. By moving the sliding joint 2 upwards are the arms 4 , like out 2 visible, spread and the scrubbing screen is clamped.

The pivot axis 7 runs in a guide 9 as a long hole in the arm 4 is trained. The leadership 9 is at an acute angle 10 to the mast 1 arranged. To open the laundry umbrella is a pull rope 11 provided that stop at the 3 is attached and over a diversion 12 on the slip joint 2 running.

By train in direction 13 on this pull rope 11 becomes the slip joint 2 in the direction 14 raised, causing the arm 4 a spreading movement 15 performs because of the arm 4 through the angled guide 9 on the pivot axis 7 is pushed sliding outward. The death of the Spreizgestells 16 is thus overcome without further action and without any special effort.

In 3 is an alternative solution according to a view 1 shown in the arm 4 a lower inclined guide 17 in the form of a long hole around the pivot axis 5 and an upper inclined guide 18 in the spreading arm 6 around the holding axis 8th is provided. This will make the train in the direction 13 on the rope 11 , as in 4 shown, a more intense spreading movement 15 achieved. The spreading frame 16 is pushed further out of his death.

In the embodiment according to 5 is as a guide a Schrägkeilführung 19 with a sloping wedge 20 on the mast and a counter-wedge 21 on the arm 4 intended. By train in direction 13 on the rope 11 becomes the slip joint 2 with the arms 4 raised. wedge 20 and counterwedge 21 glide against each other, so that the arm 4 the spreading movement 15 performs. This movement is guided by the leadership 9 ' , as previously stated, further supported.

According to the embodiment according to 6 is the oblique wedge guide 19 by magnets 22 on the mast and counter magnets 23 on the arms 4 educated. Here is the magnet 22 in a plus 24 and minus magnet 25 split while the magnet 23 has a reverse division of minus to plus magnet. This will make the arms 4 in the rest position over the gegenpoligen magnet pairs 22 . 23 held together while lifting the slip joint 2 in the direction 14 ( 6 ) the magnets 22 and 23 by sliding into the repulsive Gleichpolige position slide. The spreading process, triggered by the inclined wedge guide 19 , is additionally supported by the magnets.

According to the embodiment according to 7 and 8th is the oblique wedge guide 19 through one with the slip joint 2 connected wedge guide 26 and a counterkeeping guide 27 on the arms 4 educated. To enable the axial movement in the direction 14 is a slot guide 28 in the slip joint 2 for the pivot axis 5 intended.
