Abstract

The device serves to lower an appliance, e.g. a television set or a monitor, manually from above without exceptional force into a small item of furniture (lid cabinet) with a minimum of technology and manufacturing costs. In the lowered position, the appliance can easily be lifted again after a brief push for putting the device into operation. The weight balance, which can be precision-adjusted with slight upward pressure, is intended above all for an appliance weight of 10-50 kg at a constant lifting height of at most 40 cm. Appliances with a larger overall height can also be lowered in combination with a specially developed hollow-lid cabinet in an easily closable manner.

Description

Unter einer Hebevorrichtung für Geräte versteht man bekanntlich eine Motor-, Hydraulik- oder Gegengewichtsmechanik, die im Verhältnis zur Aufgabe meist zu kostenaufwendig ist oder zu großen Gewichts- bzw. Platzbedarf und beim Bedienen zu große Kraft erfordert.As is known, a lifting device for devices is understood an engine, hydraulic, or counterbalance mechanism that is usually too expensive in relation to the task or excessive weight or space requirements and when operating requires great strength.

Die Erfindung ermöglicht ein in ein Kleinmöbel zu stellendes Gerät nach Aufklappen des Oberblattes mit einem Minimum an technischem und räumlichem Aufwand ohne besondere Kraft zum Abstellen zu versenken. Ebenso läßt sich das Gerät nach kurzem Druck nach unten aus der Verriegelung in Betrachtungs- bzw. Arbeitshöhe evtl. durch Druckbremse verlangsamt heben. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen den oberen Schenkelpaaren der scherenartig gelagerten Rechteckrohre eine Zwischenhalterung längs drehbar angeordnet ist, die aus 2 Ovalrohren mit jeweils 5 Doppellochungen für 5 auswechselbare Zugfedern besteht, womit 9 verschiedene Gewichtsstufen entsprechend dem einzustellenden Gerät eingestellt werden können; das Gerät wird mit geringem Kraftauftrieb in die Waage gebracht, womit das schnelle Senken und Heben bis zu einer Hubdifferenz von 40-45 cm ermöglicht wird. Mit einer evtl. eingebauten Druck­ ausgleichsbremse läßt sich der Hebevorgang fast automatisch verlangsamt durchführen.The invention enables one to be placed in a small piece of furniture Device after opening the top sheet with a minimum of technical and spatial effort without special power to Parking to sink. The device can also be used short press down from the latch into consideration or the working height may be slowed down by the pressure brake. This object is achieved in that between the upper pairs of legs of the scissors-like Rectangular tubes an intermediate bracket arranged longitudinally rotatable is made of 2 oval tubes with 5 double holes each for 5 interchangeable tension springs, with which 9 different weight levels according to the one to be set Device can be set; the device comes with low force buoyancy brought into balance, with which rapid lowering and lifting up to a stroke difference of 40-45 cm is made possible. With any built-in pressure balancing brake, the lifting process is almost automatic slow down.

Ein Ausführungsbeispiel der Neuerung ist auf den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment of the innovation is in the drawings shown and is described in more detail below. It shows

Fig. 1 die Ansicht einer Schnellsenk- und Hebevorrichtung in Höchststellung für das Stufengewicht bei 3 Zug­ federn, Fig. 1 is a view of a Schnellsenk- and lifting device in its highest position for the stages weight feathers 3 in train,

Fig. 3 die Raumansicht einer Schnellsenk- und Hebevor­ richtung in Tiefststellung. Fig. 3 shows the room view of a quick lowering and lifting device in the lowest position.

Die Schnellsenk- und Hebevorrichtung besteht aus 2 in der Mitte g scherenartig gelagerten Rechteckrohren ABCD, die paarweise mit den Traversen e, davon an der oberen ein Puffer i befestigt ist, verbunden sind und an deren Enden an einer Seite mit Winkel b drehbar am Senkboden m und unteren Boden k befestigt sind und an der anderen Seite mit Rollen a die Böden m und k abrollbar berühren und deren obere Schenkelpaare über die Zwischenhalterung c mit Drehachse h und Zugfedern d miteinander verbunden sind. Beim Druck auf das auf den Senkboden m eingestellte Gerät schwenken die Schenkelpaare der Rechteckrohre ABCD in Pfeilrichtung, dabei werden die Zugfedern d gespannt und werden in Totpunktlage vom Puffer i in Tiefststellung abge­ fangen. Nach kurzem Druck nach unten auf das Gerät wird die Verriegelung aufgehoben, und der Senkboden m mit Gerät kann sich zuverlässig nach oben bewegen. Im Bedarfsfall kann zwischen den unteren Schenkelpaaren eine Druckbremse f den Hebevorgang verlangsamen. The Schnellsenk- and lifting device consists of 2 in the middle g scissors-like layered rectangular tubes ABCD that a buffer is paired with the traverses e, of which the top of the fixed i, are connected, and b at the ends on one side with angular rotatably mounted on the false bottom m and lower floor k are attached and on the other side with rollers a touch the floors m and k in a rollable manner and their upper pair of legs are connected to one another via the intermediate bracket c with the axis of rotation h and tension springs d . When the device set on the false floor m is pressed, the pairs of legs of the rectangular tubes ABCD swivel in the direction of the arrow, the tension springs d are tensioned and are caught in the dead center position by the buffer i in the lowest position. After briefly pressing down on the device, the lock is released and the false floor m with the device can move reliably upwards. If necessary, a pressure brake f can slow down the lifting process between the lower pairs of legs.
