Description

Die Erfindung betrifft eine Haartrockenhaubenach der Gattung des Oberbegriffs des Anspruchs 1.The invention relates to a hair dryer hood according to the preamble of the preamble of claim 1.

Eine derartige Haartrockenhaube mit einer Vorrichtung zum Ausgleich eines Übergewichts der von einer Arbeitsstellung in eine Parkstellung schwenkbaren Haartrockenhaube um eine waagerechte Achse mittels eines unteren und eines oberen Gelenkteils, wobei das untere und obere Gelenkteil als eine Baueinheit ausgebildet ist, ist aus der DE-1059159-B bekannt. Diese Vorrichtung dient dazu, eine Haartrockenhaube aus einer ersten Stellung ("Parkstellung") in eine zweite Stellung ("Arbeitsstellung") zu kippen und umgekehrt. Hierbei besteht die Gefahr, dass die Haartrockenhaube beim manuellen Verstellen von der Parkstellung in die Arbeitsstellung ungewollt in die Arbeitsstellung fällt, wodurch die Haartrockenhaube erschüttert wird. Bei dieser Haartrockenhaube arbeitet eine Vorrichtung zum Ausgleich des Übergewichts der um eine waagrechte Achse schwenkbaren Haartrockenhaube mit einem oberen Gelenkteil mittels einer Kraft einer Druckfeder konstruktiv bedingt sehr ungenau und läßt sich nur unflexibel einsetzen, da die Vorrichtung mit der Haartrockenhaube und einem Tragelement eine Montageeinheit bildet, was auch zu hohen Herstellkosten führt.Such a hair dryer hood with a device for compensating for an overweight of the hair dryer hood pivotable from a working position into a parking position about a horizontal axis by means of a lower and an upper hinge part, wherein the lower and upper hinge part is formed as a structural unit, is known from DE-1059159-B known. This device is used to tilt a hair dryer hood from a first position ("park position") to a second position ("working position") and vice versa. There is a risk that the hair dryer hood accidentally falls during manual adjustment of the parking position in the working position in the working position, whereby the hair dryer hood is shaken. In this hair dryer hood works a device to compensate for the excess weight of the pivotable about a horizontal axis hair dryer hood with an upper hinge part by a force of a compression spring constructively very imprecise and can be used only inflexible, since the device forms a mounting unit with the hair dryer hood and a support member, which also leads to high production costs.

In der Fig. 1 ist eine Vorrichtung 1 in einer Arbeitsstellung dargestellt mit einem unteren und einem oberen Gelenkteil 2,3, wobei eine Einrichtung 4 zum Ausgleich eines Übergewichts einer um eine waagrechte Achse X schwenkbare Haartrockenhaube 26 (Fig. 10) über das obere Gelenkteil 3 mittels einer Kraft einer Druckfeder 6 vorgesehen ist. Das untere Gelenkteil 2 ist mit einem Kolben 7 versehen, der durch die Druckfeder 6 mit einem im oberen Gelenkteil 3 angeordneten Kurventeil 8 gleitend in Kraftschluss steht, wobei das Kurventeil 8 einen derartigen Kurvenverlauf 9 aufweist, dass ein stetiger Ausgleich des Übergewichts erfolgt. Die Druckfeder 6 ist mittels einer Stellschraube 21 und einer drehfesten Mutter 40 vorgespannt und stützt sich als Gegenlager auf einen Konus 41 ab, wobei der Konus 41 in einer dazu komplementären Aufnahme 42 am unteren Ende des unteren Gelenkteils 2 angeordnet ist, dass der Konus 41 derart mit Schlitzen 43 versehen ist, dass er wie eine Spannzange auf die Stellschraube 21 wirkt, die in diesem Bereich kein Gewinde aufweist, wodurch von der Parkstellung in die Arbeitstellung eine progressive Friktion erfolgt, die ein Fallen der Haartrockenhaube 26 in eine Arbeitsposition verhindert. Das untere Gelenkteil 2 ist mit einem ersten Kupplungsteil 10 für ein Tragelement 11 (Fig.10) und das obere Gelenkteil 3 mit einem zweiten Kupplungsteil 12 für die Haartrockenhaube 26 versehen, wobei das untere und das obere Gelenkteil 2,3 als eine Baueinheit 13 ausgebildet ist.In Fig. 1, a device 1 is shown in a working position with a lower and an upper hinge part 2,3, wherein means 4 for compensating for an overweight of a horizontal axis X pivotable hair dryer hood 26 (Fig. 10) on the upper hinge part 3 is provided by a force of a compression spring 6. The lower joint part 2 is provided with a piston 7 which is in sliding connection by the compression spring 6 with a cam part 8 arranged in the upper joint part 3, wherein the cam part 8 has such a course 9 that there is a steady compensation of the excess weight. The compression spring 6 is biased by means of an adjusting screw 21 and a non-rotatable nut 40 and is supported as an abutment on a cone 41, wherein the cone 41 is arranged in a complementary receptacle 42 at the lower end of the lower joint part 2 that the cone 41 so provided with slots 43 that it acts like a collet on the screw 21, which has no thread in this area, whereby a progressive friction takes place from the parking position to the working position, which prevents falling of the hair dryer hood 26 in a working position. The lower joint part 2 is provided with a first coupling part 10 for a support element 11 (FIG. 10) and the upper joint part 3 with a second coupling part 12 for the hair-drying hood 26, wherein the lower and the upper joint part 2, 3 are designed as a structural unit 13 is.

Solche Schwenkvorrichtungen ( DE-1059159-B ) werden zum Beispiel zum beweglichen Verbinden von Haartrockenhauben mit Stativen verwendet und erlauben ein komfortables Positionieren der Haartrockenhaube. Nachteilig bisher ist der nicht progressive Drehmomentverlauf beim Drehen bzw. Kippen des Gelenks, der durch eine aufwendige Friktion ausgeglichen werden muss um ein zu schnelles Kippen der Haartrockenhaube zu vermeiden. Diese Friktion ist bei den bisher bekannten Lösungen für alle Drehwinkel gleich groß (eine am Gelenk befestigten Haartrockenhaube erzeugt aber ein progressives Drehmoment).Such pivoting devices ( DE-1059159-B ) are used, for example, for the movable connection of hair dryer hoods with tripods and allow a comfortable positioning of the hair dryer hood. A disadvantage so far is the non-progressive torque curve when turning or tilting of the joint, which must be compensated by a complex friction in order to avoid too rapid tilting of the hair dryer hood. This friction is equal in the previously known solutions for all angles of rotation (but a hair dryer hood attached to the joint produces a progressive torque).

Bei der Vorrichtung 1 verläuft die Bewegung des Kolbens 7 nicht linear mit dem Drehwinkel des Gelenks 2,3, sondern progressiv durch die besondere Form der Gleitfläche. Außerdem dadurch, dass die Friktion zwischen den Gleitflächen mit zunehmendem Federdruck größer wird. Ein besonderer Vorteil ergibt sich aus der Friktionsdifferenz zwischen dem Drehen in Richtung Arbeitsposition und Richtung Aufsetzposition, wodurch das Anheben der Haartrockenhaube 26 erleichtert wird.In the device 1, the movement of the piston 7 is not linear with the angle of rotation of the joint 2,3, but progressively by the particular shape of the sliding surface. In addition, the fact that the friction between the sliding surfaces with increasing spring pressure is greater. A particular advantage results from the friction difference between the rotation in the direction of the working position and the direction of placement, whereby the lifting of the hair dryer hood 26 is facilitated.

Für eine Stromversorgung einer Haartrockenhaube 26 ist das untere Gelenkteil 2 mit einer Kabeleinführung 14 für ein Kabel 15 versehen, wobei für eine Nichtgebrauchs- beziehungsweise Parkstellung (Fig. 2 und 11) der Vorrichtung 1 wahlweise das untere Gelenkteil 2 mit einer Kabelwickelaufnahme 16 versehen ist.For a power supply of a hair dryer hood 26, the lower hinge part 2 is provided with a cable entry 14 for a cable 15, wherein for a non-use or parking position (Fig. 2 and 11) of the device 1 optionally the lower hinge part 2 is provided with a cable winding receptacle 16.

Fig. 4 zeigt ein drittes Kupplungsteil 17 mit einer Haartrockenhaube 26, wobei nach der Fig. 5 für eine einfach herzustellende mechanische Verbindung mit der Vorrichtung 1 das dritte Kupplungsteil 17 mit dem dazu korrespondierenden zweiten Kupplungsteil 12 des oberen Gelenkteils 3 verkuppelt ist. Für eine zusätzlich einfach herzustellende elektrische Verbindung der Haartrockenhaube 26 mit der Vorrichtung 1 ist das zweite Kupplungsteil 12 des oberen Gelenkteils 3 mit einer ersten Elektrokupplung 18 und das dritte Kupplungsteil 17 der Haartrockenhaube 26 mit einer dazu korrespondierenden zweiten Elektrokupplung 19 (gestrichelt angedeutet) versehen.FIG. 4 shows a third coupling part 17 with a hair dryer hood 26, wherein according to FIG. 5 the third coupling part 17 is coupled with the second coupling part 12 of the upper joint part 3 corresponding thereto for an easily produced mechanical connection with the device 1. For an additionally easy to produce electrical connection of the hair dryer hood 26 with the device 1, the second coupling part 12 of the upper joint part 3 with a first electric clutch 18 and the third coupling part 17 of the hair dryer hood 26 with a corresponding thereto second electric clutch 19 (indicated by dashed lines) provided.

Dadurch, dass dem Kolben 7 eine Federkrafteinstelleinrichtung 20 (Fig. 1 bis 3 und 5) zugeordnet ist, läßt sich individuell ein Ausgleich eines Übergewichts einer Haartrockenhaube 26 einstellen, wobei vorzugsweise die Federkrafteinstelleinrichtung 20 mit einer Stellschraube 21 versehen ist, die vom unteren Ende des unteren Gelenkteils 2 mit einem nicht dargestellten Werkzeug verstellbar ist.Characterized in that the piston 7 is a Federkrafteinstelleinrichtung 20 (Fig. 1 to 3 and 5) is assigned, can be adjusted individually balancing an overweight of a hair dryer hood 26, preferably the Federkrafteinstelleinrichtung 20 is provided with a screw 21 which extends from the lower end of lower joint part 2 with a tool, not shown, is adjustable.

In den Fig. 6 bis 9 ist der Konus 41 dargestellt, der mit vier Schlitzen 43 versehen ist und dadurch wie eine Spannzange wirkt. Auf diesen Konus 41 drückt die Feder 6. Dadurch wird eine hohe Friktion zwischen der Schraube 21 und dem Konus 41 erzeugt. Da die Schraube 21 bei der Bewegung des Gelenks 2,3 in Richtung Arbeitsstellung nach unten bewegt wird, verhindert diese Friktion, dass das Gelenk 2,3 mit der Haartrockenhaube 26 schlagartig in die Arbeitsstellung fällt.In Figs. 6 to 9, the cone 41 is shown, which is provided with four slots 43 and thereby acts like a collet. On this cone 41 presses the spring 6. This creates a high friction between the screw 21 and the cone 41. Since the screw 21 is moved downward in the direction of the working position during the movement of the joint 2, 3, this friction prevents that the joint 2,3 with the hair dryer hood 26 abruptly falls into the working position.

Die Vorrichtung 1 weist eine Schutzverkleidung 22 auf, mit der das untere und das obere Gelenkteil 2,3 mittels eines unteren und eines oberen teilweise überlappenden kugelschalenartigen Verkleidungsteiles 23,24 geschützt ist, die vorzugsweise aus Kunststoff bestehen. Weitere Einzelheiten zeigen die Fig. 20 bis 27, wobei das untere Verkleidungsteil 23 in den Fig. 20 bis 23 und das obere Verkleidungsteil 24 in den Fig. 24 bis 27 dargestellt ist, die vorzugsweise jeweils als einstückiges Kunststoffspritzteil hergestellt sind.The device 1 has a protective covering 22, with which the lower and the upper hinge part 2,3 is protected by means of a lower and an upper partially overlapping spherical shell-like covering part 23,24, which are preferably made of plastic. Further details are shown in FIGS. 20 to 27, wherein the lower trim part 23 is shown in Figs. 20 to 23 and the upper trim part 24 in Figs. 24 to 27, which are preferably made respectively as a one-piece plastic injection molded part.

In den Fig. 28 und 28 sind als vergrößerte Einzelheiten die erste Elektrokupplung 18 als eine Steckdose und die zweite Elektrokupplung 19 als ein Stecker dargestellt, wobei die Fig. 29 eine Verkupplung des Steckers mit der Steckdose zeigt.28 and 28 are shown as enlarged details the first electric coupling 18 as a socket and the second electric coupling 19 as a plug, wherein Fig. 29 shows a coupling of the plug with the socket.

Zusammengefasst ist der Gegenstand der Erfindung eine Haartrockenhaube 26 mit einem Gelenk 2,3 mit zwei tragenden Gelenkteilen 2,3, die durch eine Achse X drehbar verbunden sind, wobei eine Feder 5 über einen Kolben 7, einer Schraube 21 und einem Konus 41 so abgestimmt sind, dass ein Kippen um die Achse X erst nach Überwindung eines für jede Winkelstellung sich ergebenden Drehmoments erfolgen kann. Die Verdrehung ist durch integrierte Anschläge begrenzt. Zusätzlich ist die Schraubenmutter 40 verdrehsicher angeordnet, wodurch eine sehr einfache Drehmomentfeineinstellung über die Schraube 21 von außen erfolgen kann.In summary, the subject of the invention is a hair dryer hood 26 with a joint 2,3 with two supporting joint parts 2,3, which are rotatably connected by an axis X, wherein a spring 5 via a piston 7, a screw 21 and a cone 41 so tuned are that tilting about the axis X can take place only after overcoming for each angular position resulting torque. The rotation is limited by integrated stops. In addition, the nut 40 is arranged against rotation, whereby a very simple torque fine adjustment via the screw 21 can be done from the outside.
