  • FIGS. 1 and 2 show a cradle I mounted for oscillation on a tubular chassis 2 by means of pivots 3, integral with upper edges 4 of end panels 5 of the cradle 1. These pivots 3 engage within and are supported by bearings 6 of chassis 2.
  • An electromagnetic device 7 for maintaining oscillationsof the cradle l is mounted so as to be adjustable in height on a cable 8 stretched between a lower crosspiece 9 and an inclined rod 10 of chassis 2.
  • a mobile part 11 of the device 7 is articularly connected by a cable 12 to the upper edge 4 of one of the panels 5 of cradle 1, at a point between the pivot 3 and one of the ends of the edge 4.
  • a case 13 containing a switch 14 controlled by an extension to one of the pivots 3 is mounted on the chassis 2 at the height of one of the bearings 6.
  • the switch 14 is connected on the one hand to the main electricity supply by means of a cable 15 and, on the other hand, to the electromagnetic device 7 for the purpose of providing an intermittent supply of electric current to the latter.
  • the electromagnetic device for maintaining oscillation of cradle 1 comprises an electromagnet l6 housed in a casing 17 forming the fixed part of the device mounted on cable 8.
  • the mobile part 11 of device 7 is formed by a ferromagnetic core 18,
  • This ferromagnetic core 18 has at its upper end a ring 19 by means of which it can be connected to one of the ends of cable 12.
  • the mobile core 18 has an outer sheath 20 of patent leather and is coaxially engaged, with friction, in a hollow coil support 21 of rectangular transversal section.
  • Support 21 carries a winding 22 of the electromagnet 16, which has a U-shaped body 23 composed of strips of a high permeability ferromagnetic material, similar to those of the core 18.
  • the inner face of the hollow coil-support 21 is covered with a lining 24 of strips of glass which contacts the surface of the patent leather sheath 20 surrounding mobile core 18.
  • the switch 14 for providing an intermittent supply of electric current to the device 7 comprises a contact unit 26.
  • Contact elements 27, 28 of unit 26 are mounted facing one another at the free ends of resilient spring blades 29, 30 respectively which are mounted, generally parallel to one another, by their other ends on an insulating support 39, each blade being connected to a terminal 40.
  • the blade-29 has, on its face opposite that carrying the contact element 27, a protuberance 31 which is adapted to cooperate with a control member 32 to close the contact unit 26 of switch 14.
  • the protuberance 31 is formed by a piece of glass stuck onto blade 29.
  • the control member 32 includes an arm 33 keyed on one of the pivots 3 of cradle l and extending outwardly from the corresponding bearing 6 of chassis 2.
  • a support plate 34 carried by one of the faces of arm 33 towards the free end thereof, carries one of the parts of a hinge 35, the pivoting axis of which is parallel to the arm 33.
  • the other part of hinge 35 carries, outside its free end edge, a rubber roller 36.
  • the hinge 35 is mounted between a block 37 of rubber on plate 34 and a rubber blade 38.
  • the spring blade 29 is more rigid than the rubber blade 38 so that the roller 36, which is located facing the surface of blade 29 which carries the protuberance 31, is lifted up by the protuberance 31 when the arm 33 pivots in the counter-clockwise direction (looking at FIG. 4). Consequently, the contact unit 26 does not close when the pivot 3 turns in the counter-clockwise direction (looking at FIGS. 2 and 4). However, when the pivot 3 turns in the clockwise direction (looking at FIGS.
  • the case 13 contains a second switch controlled by a timer mechanism, which enables the supply to the electromagnetic device 7 for maintaining the oscillations of cradle l to be switched off after a period of time that can be adjusted by means of a control knob 41 (FIG. 1).
  • the case 13 also has an indicator light 42 which is switched off when the second switch opens.
  • the chassis 2 also has a hoop 43 on which a fan-blade 44 is pivotally suspended above cradle 1, blade 44 being actuated by a rod 45 which is pivoted on the one hand to the upper edge 4 of an end panel of the cradle 1 and, on the other hand, to an arm 46 projecting at right-angles to the upper edge of blade 44.
  • An electric-gramophone 47 of the type in which a disc is introduced in a slot, and which incorporates a bed-side lamp 40, is also suspended from the hoop 43.
  • the gramophone 47 is supplied with electric current from the case 13, and the timer mechanism for actuation of the second switch enables both the lamp 48 and the gramophone 47, which may advantageously play a disc with lullaby music, to be switched off after a period of time that can be adjusted by means of the knob 41.
  • the switch 14 In operation, as the cradle 1 rocks, after each time that the direction of oscillation of cradle 1 changes from counter-clockwise to clockwise (looking at FIG. 2), the switch 14 is closed for a certain period of time to supply a pulse of electric current to the electromagnet 16 which provides a downward impulse on the core 18 tending to oscillate the cradle 1 in the clockwise direction.
  • FIGS. 5 and 6 show a rocking chair 52 with rockers 53 provided, on a cross-piece 54 between the rockers 53, with an electromagnetic device 7a for maintaining oscillations of the chair.
  • the device 7a is similar to device 7 of FIG. 3, and the same reference numerals designate the same or equivalent parts of the two devices. However, the device 7a differs from the above-described device 7 in that its casing 17 houses the switch 14 for providing an intermittent supply of electric current. Device 7a is thus directly connected to the electric mains by a cable 15. Also, the mobile ferromagnetic core 18 is extended at its lower end by a rod 49 passing through the elastic stop 25 (not shown in FIG. 6) and through a bore 50 in the base of the U-shaped body 23.
  • a return spring 56 mounted about the rod 58, ensures pivoting of the arm 33 in the clockwise direction (looking at FIG. 6) and the closure of contact unit 26 by means of a roller 36.
  • the electromagnetic device 7a for maintaining oscillation of rocking chair 52 could similarly be mounted on a cross-piece of a rocking horse or any other piece of furniture or plaything mounted on rockers. Such devices may also be mounted on each of two cross-pieces disposed towards the rear and front ends of the rockers .of a piece of furniture.
  • swings of the type comprising a seat and harness suspended by a spring or an elastically extensible cable, available under the trade name Yupla," can be provided with a support protruding under the seat and carrying at its lower end an oscillation maintenance device 7a.
  • see-saws adapted to oscillate about a horizontal axis may be provided with a device 7a under seats at its ends.
  • the core 18 could be fixed and the electromagnet mobile. It is also possible to mount the switch 14 in the casing 17 of the device 7, as for the device 7a.
  • 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
