Oscillating furniture and playthings

Claim 2

A piece of oscillating furniture comprising at least one device imparting an oscillating movement thereto, said device including first and second parts movable relative to one another, the first part comprising an electromagnet including a body and a hollow coil support, the second part comprising a core of ferromagnetic material engaged within and disposed axially of said coil support, an outer sheath of patent leather on said core, a glass lining on an inner surface of the coil support, said sheath being in frictional engagement with said lining, means for intermittently supplying electric current to the electromagnet after a change in the direction of oscillation of the piece of furniture to provide an impulse tending to oscillate it in a new direction of oscillation, said means comprising a blade switch, an oscillating control arm mounted on said piece of furniture, a member pivotally mounted on said arm towards a free end thereof and engageable with said blade switch, elastic return means acting on said member, said member being pivotable in one direction against the action of said elastic return means and a stop member limiting pivotal movement of said member relative to said arm in the other direction, said piece of furniture further comprising a chassis, bearings on said chassis, pivot means supported by said bearings, an oscillating body suspended by said pivot means, said pivot means actuating said oscillating control arm of the switch, one of said parts of the oscillating movement device being connected to said body and the other to said chassis.

Claim 3

A piece of furniture as claimed in claim 1, in which said electromagnet includes a U-shaped body, one of the ends of said coil support resting on the base of the U of said body, and a stop member of elastically compressible material at said one end of the coil support.

Claim 4

A piece of furniture as claimed in claim 1, in which one blade of said switch has a protuberance facing said member pivotally mounted on the oscillating arm, contact elements carried by the blades of said switch, said member cooperating with said protuberance to move said contact elements into engagement with each other when the oscillating arm oscillates in a direction to make said element tend to pivot in said other direction.

Claim 5

A piece of oscillating furniture comprising at least one device imparting an oscillating movemenT thereto, said device including first and second parts movable relative to one another, the first part comprising an electromagnet including a body and a hollow coil support, the second part comprising a core of ferromagnetic material engaged within and disposed axially of said coil support, an outer sheath of patent leather on said core, a glass lining on an inner surface of the coil support, said sheath being in frictional engagement with said lining, means for intermittently supplying electric current to the electromagnet after a change in the direction of oscillation of the piece of furniture to provide an impulse tending to oscillate it in a new direction of oscillation, said means comprising a blade switch, an oscillating control arm mounted on said piece of furniture, a member pivotally mounted on said arm towards a free end thereof and engageable with said blade switch, elastic return means acting on said member, said member being pivotable in one direction against the action of said elastic return means and a stop member limiting pivotal movement of said member relative to said arm in the other direction, said piece of furniture being mounted on a rocker, said rocker adapted to oscillate on a supporting surface, a casing mounted on said rocker and containing said first part of said device, means connecting said oscillating control arm to a free end of said core, said ferromagnetic core including a rod connected to one end thereof, said rod extending through said body of the electromagnet and adapted to engage said supporting surface and maintain the oscillations of said piece of furniture by propulsion upon closing of said switch.

Claim 6

A piece of oscillating furniture comprising at least one device imparting an oscillating movemenT thereto, said device including first and second parts movable relative to one another, the first part comprising an electromagnet including a body and a hollow coil support, the second part comprising a core of ferromagnetic material engaged within and disposed axially of said coil support, an outer sheath of patent leather on said core, a glass lining on an inner surface of the coil support, said sheath being in frictional engagement with said lining, means for intermittently supplying electric current to the electromagnet after a change in the direction of oscillation of the piece of furniture to provide an impulse tending to oscillate it in a new direction of oscillation, said means comprising a blade switch, an oscillating control arm mounted on said piece of furniture, a member pivotally mounted on said arm towards a free end thereof and engageable with said blade switch, elastic return means acting on said member, said member being pivotable in one direction against the action of said elastic return means and a stop member limiting pivotal movement of said member relative to said arm in the other direction, said piece of furniture being mounted on a rocker, said rocker adapted to oscillate on a supporting surface, a casing mounted on said rocker and containing said first part of said device, means connecting said oscillating control arm to a free end of said core, said ferromagnetic core including a rod connected to one end thereof, said rod extending through said body of the electromagnet and adapted to engage said supporting surface and maintain the oscillations of said piece of furniture by propulsion upon closing of said switch.
