Abstract

Drive system (2) for a spring cradle system (100), in particular for a child's or baby's spring cradle, for generating an oscillating movement, comprising a tension element (4) with a distal end adapted to be fixed to an oscillating element, a drive unit (21) adapted to increase and decrease a free length of the tension element (4) to change a position of the oscillating element relative to the drive system (2), and a control unit (22) adapted to control the drive unit (21) so that a pretensioning force acts on the tension element (4) regardless of the position of the oscillating element relative to the drive system (2). Further provided is a spring cradle system (100) comprising the drive system and a method for simulating an elastic clamping element.

Abstract

The invention relates to a pulley (1) for a swing hammock drive for driving a baby swing hammock. The pulley (1) is designed to wind or unwind a tension element (13) during a rotation about a rotational axis (D). The pulley (1) has a tension element receiving section (2) which extends on a lateral surface (11) of the pulley (1), and the tension element receiving section (2) has a depression (3) which runs about the rotational axis and is recessed in the radial direction (R) of the pulley (1). The invention additionally relates to a pulley system (100) and to a method for winding or unwinding a tension element (13).

Abstract

The invention relates to a swing hammock suspension (1) for connecting at least one spring element (2) to a receiving device (3). The swing hammock suspension (1) comprises at least one securing element (4) for securing the spring element (2) and at least two hook elements (5) for securing the receiving device (3). The at least one securing element (4) and the at least two hook elements (5) are mutually spaced in a first direction (R1), and the two hook elements (5) are mutually spaced in a second direction (R2) which is substantially orthogonal to the first direction (R1). The invention additionally relates to a swing hammock system (10) and to a method for connecting a receiving device (3) to at least one spring element (2).

Abstract

A baby-cradle hook system (1) for connecting a movable baby cradle (11) to a holding element (2) in a main direction (H) is provided. The baby-cradle hook system (1) comprises a first hook portion (3) with a first holding region (31) for holding a holding part (91) of the baby cradle (11), and a second hook portion (4) with a second holding region (41) for holding a cross-sectionally rectangular holding part (6) of the holding element (2) and with a second insertion region (42) for inserting the holding part (6) of the holding element (2) into the holding region (41). The second holding region (41) is designed such that only in a first orientation can the holding part (6) of the holding element (2) be held in the holding region. The second insertion region (42) is designed such that only in a second orientation can the holding part (6) of the holding element (2) pass through the insertion region in a direction of insertion (R1). The first orientation and the second orientation differ from each other. A spring-cradle system with the baby-cradle hook system (1) is also provided.
