ABSTRACT:
An apparatus for the displacement of articles between positions located substantially in a common plane which includes a first carrier member (4) and a second carrier member (5) which are pivotally interconnected to one another by a plate (7) in immediate association with the one end (40, 50) of each respective carrier member. The first carrier member (4) is, in immediate association with its other end (41) movably journaled in a suspension device (6), while the second carrier member (5) is provided, at its other end (51), with a connector piece (55). The connector piece is disposed for temporary reception and/or retention of an article and delivery, respectively, of the article after displacement to the intended position. A drive mechanism is connected, by a transmission (3), to the connector piece (55) for regulating the distance between the connector piece and the suspension device (6). In the plate (7), the support members are interconnected by couplings (42, 52) which positively guide the carrier arms for concordant pivotal movement upon alteration of the distance between the connector piece (55) and the suspension device (6). As a result, there will always be obtained a linear movement for the connector piece (55) on its displacmeent in relation to the suspension device.
