A device for moving a support (2) for shelves (19), cupboards, tables or similar along a path, which support (2) is suspended in arm (1) that is pivotally connected to a base (9) about an axis of rotation (6) at one end of the arm (1), comprising:a load transmission means (13), for example a cogwheel, at the axis of rotation (6), which is connected to the base (9),at least one rotating means (16), for example a cogwheel, pivotally mounted on the arm (1) spaced apart from the load transmission means (13),an elongate rotation transmission means (14), for example an endless chain, which extends at least from the load transmission means (13) to the rotating means (16),the rotating means (16) being connected to the support (2), so that when the arm (1) is turned about the axis of rotation (6) the load transmission means (13) transmits the relative rotational movement between the arm (1) and the load transmission means (13) via the rotation transmission means (14) to the rotating means (16), so that the position of the support (2) is controlled dependent upon the position of the arm (1). Thus, it is possible to hold, say, a shelf (19) or a cupboard in the same position relative to the vertical plane whilst it is being raised and lowered. |
