EP2354297B1 - Rotary clothes drier - Google Patents

Abstract

The clothes dryer is provided with lifting arms (1) in the resting position, and a lift cable (8). A retraction device is provided for retracting the lift cable into a component of the clothes dryer, particular in the lifting arm or in a pole (4) provided in a support arm (6).

Description

The invention relates to a rotary clothes dryer with support arms according to claim 1, which are selectively convertible into a rest position or in an expanded position, and wherein an opening mechanism is provided for complete transfer to the spread position, having an elevator rope.

Out EP 0 649 935 A1 is such a rotary dryer known, but has a number of disadvantages with regard to their operation. On the one hand, the force with which the user has to pull on the elevator rope in order to open the clothes dryer is relatively large. Although the proposed Aufspreizmechanik facilitates overcoming the dead center, but the force that is required for complete transfer to the Aufspreizstellung, yet relatively high, since the force exerted by the user on the elevator rope pulling force is unchanged, especially mechanically unreinforced, is used. On the other hand, it is disadvantageous that after completion of complete transfer of the support arms in the Aufspreizstellung the elevator rope sags limp, so that it beats regularly against the mast, for example, in light winds, arranged with the handlebar end against the mast and causes unwanted noise. In addition, there is a risk that the free-hanging elevator rope tangled to the clothes dryer or in itself, so that the folding of the clothes dryer is hindered.

Next is the in the EP 0 649 935 A1 disclosed rotary dryer designed with respect to their structural design at the top of the mast relatively expensive. The mast end must be closed by means of a projecting beyond the actual mast end cap to cover the projecting beyond the mast spreader can. In addition, the mast end must have a guide members comprehensive construction, which is able to prevent tilting or tilting of the spreader safely. Because the fact that the spreader stands on the mast end and is to be pressed into the mast, he is in a position that would be unstable without additional support and guide members.

From the WO 01/14626 A1 For example, a rotary dryer is known, which has an elevator mechanism for the lines for hanging the laundry. However, no elevator mechanism for spreading the clothes dryer is described here.

The DE 198 04 608 C1 again describes an opening mechanism for a garden or market umbrella. This has a sliding sleeve, which is moved up and down via an integrated pulley in the mast.

It is the object of the present invention to provide a rotary dryer, which can be actuated even more easily in particular with respect to the first dead center when opening the rotary dryer and also improves the operation and handling with respect to the elevator rope. In addition, the construction should be simplified compared to the known from the prior art rotary dryer.

The object is achieved by a clothes dryer, which is characterized in that a collection device for pulling the elevator rope is provided in a component of the rotary clothes dryer, in particular in a support arm and / or in a mast and / or in a support arm, wherein the collection device a slidably mounted weight body for the collection of the elevator rope, which is formed by an expansion body of the Vorspreizmechanik.

This embodiment of a rotary dryer has the advantage that a particularly smooth and comfortable operation is possible. The user must apply especially at the beginning of the Aufspreizvorganges no great forces and the elevator rope is pulled in comfortable manner.

Advantageously, the Vorspreizmechanik at least one longitudinally displaceable expansion body. For a very special one Embodiment is provided, that the expansion body is conical and / or has at least one run-on slope. It can also be provided that the spreader is at least partially disposed in a mast and / or that the spreader is longitudinally displaceable in a mast and / or that the spreader is longitudinally displaceable on a mast. A particularly advantageous embodiment is characterized in that spreading elements are arranged on the support arms and / or on support arms, which act together with the expansion body during the pre-spreading process.

With the Aufspreizmechanik pivoting of the support arms from the rest position is directly or indirectly effected and for complete transfer to the Aufspreizstellung an opening mechanism is provided which has an elevator rope. The collection device is used for pulling the elevator rope into a component of the rotary clothes drier, in particular in a support arm and / or in a mast and / or in a support arm. According to the invention, the collection device has a slidably mounted weight body and / or the expansion body forms a slidably mounted weight body for the entry of the elevator rope.

• Fig. 1 zeigt eine Wäschespinne mit Tragarmen 1, die wahlweise in eine Ruhestellung oder in eine Aufspreizstellung überführbar sind. Es ist eine Vorspreizmechanik zum Bewegen der Tragarme aus der Ruhelage mit einem Flaschenzug 2 zum Betätigen der Vorspreizmechanik vorgesehen. Die Vorspreizmechanik weist einen längsverschiebbaren Spreizkörper 3 auf, der kegelförmig ausgebildet ist und längsverschiebbar in einem Mast 4 angeordnet ist. Wie in Fig.1 gezeigt bildet der Spreizkörper 3 einen Gewichtskörper, der bevorzugt frei hängend im Mast 4 aufgenommen ist. Hierbei bildet das Aufzugsseil 8 mit den Umlenkrollen 10 einen Flaschenzug.

In the drawing, the subject invention is shown schematically and will be described below with reference to the figures, wherein like-acting elements are provided with the same reference numerals. Showing:

• Fig. 1 shows a rotary clothes dryer with support arms 1, which are selectively convertible into a rest position or in an expanded position. There is provided a Vorspreizmechanik for moving the support arms from the rest position with a tackle 2 for actuating the Vorspreizmechanik. The Vorspreizmechanik has a longitudinally displaceable expansion body 3, which is conical and longitudinally displaceable in a mast 4 is arranged. As in Fig.1 shown, the expansion body 3 forms a weight body, which is preferably added freely suspended in the mast 4. Here, the elevator rope 8 forms a pulley with the pulleys 10.

The support arms 1 are articulated on a sliding sleeve 5 mounted slidably along the mast 4. The support arms 1 are connected via support arms 6 hingedly connected to a holding star, not shown on the head of the mast 4. On the support arms 6 spreading elements 7 are arranged, which cooperate with the expansion body 3 during the pre-spreading process. To open the clothes dryer, an opening mechanism with an elevator rope 8 is provided. The elevator rope 8 is guided via a first deflection roller 9 arranged on the sliding sleeve and via further deflection rollers 10, which are parts of the pulley block 2. It is a collection device for pulling the elevator rope 8 provided in the mast 4, wherein the spreader 3 forms a slidably mounted weight body for the collection of the elevator rope.

It is of course not necessarily required that the elevator rope 8 is deflected over the two pulleys 10 arranged on the mast. The non - user end of the rope to be gripped in Fig. 1 for the purpose of the most even distribution of the elevator force is attached to the sliding sleeve 5, can of course also at the upper end of the mast 4 or this top side closing cap (not shown) may be arranged. It should also be noted that the deflection of the elevator rope on the roller 10 articulated on the spreader 3 is not absolutely necessary. Particularly in the case of a lighter and rather smaller rotary clothes dryer, the end of the elevator rope 8 can also be fastened directly to the spreader body. In this way, although waived on the pulley 2 guaranteed increase in the force acting on the spreader force. In a sufficiently small or light spin dryer construction, this disadvantage can be taken into account.

The invention has been described with reference to a particular embodiment. However, it is to be understood that changes and modifications may be made without departing from the scope of the following claims.
