Abstract
A motion imparting leg for imparting an oscillating or reciprocating rectilinear motion to a bed for rocking the bed is provided. The motion imparting leg comprises a base, an upper member movable relative to the base for imparting the oscillating or reciprocating rectilinear motion, a linear shaft motor for driving movement of the upper member, a position sensor for determining the position of the linear shaft motor or the position of the upper member, and a motor controller for controlling the linear shaft motor based on data from the position sensor.
Claims20
A motion imparting leg for imparting an oscillating or reciprocating rectilinear motion to a bed for rocking the bed, the motion imparting leg comprising:
- a base;
- an upper member movable relative to the base for imparting the oscillating or reciprocating rectilinear motion;
- a linear shaft motor for driving rectilinear movement of the upper member, the linear shaft motor comprising a fixed part and a moving part spaced apart from each other, the moving part being rectilinearly movable relative to the fixed part;
- a position sensor for determining a position of the linear shaft motor or a position of the upper member;
- a motor controller for controlling the linear shaft motor based on data from the position sensor;
- a rectilinear motion assembly disposed between and coupled to the moving part of the linear shaft motor and the upper member, the rectilinear motion assembly comprising:
- a carriage;
- and
- a linear slider assembly comprising a first slider element connected to each side of the carriage and a second slider element connected to the base, wherein the second slider element is disposed between the linear shaft motor and each first slider element.
A motion imparting device for imparting an oscillating or reciprocating rectilinear motion to an object, the motion imparting device comprising:
- a base;
- an upper member movable on a motion path relative to the base for imparting the oscillating or reciprocating rectilinear motion to the object;
- a drive or guide structure positioned at least partially between the base and the upper member;
- a linear shaft motor for driving rectilinear movement of the upper member, the linear shaft motor comprising a fixed part and a moving part spaced apart from each other with a gap therebetween, the moving part being rectilinearly movable relative to the fixed part;
- and
- wherein the upper member is displaceable in a horizontal plane independently of its movement along the motion path, allowing for at least one of rotation or translation of at least part of the upper member relative to the base and the drive or guide structure.
