Abstract

An electric rocking chair comprises a chair installed on a support base having a trapezoidal form with the two inclined faces disposed at the front and at the rear sides of the chair, the side'"'"'s faces supporting the chair. The chair is electrically moved front to back by means of displacement, such as wheels, attached to the front and to the rear under the chair and intended to roll along both inclined faces on a see saw movement operated by means of an electric actuator disposal. The rocking of the chair is performed in two movements, when front wheels are going down along the front inclined face, rear wheels are going up along the rear inclined face, thus inclining the chair forward and the opposite movement inclines the chair backward. Means of maintaining the wheels during the rolling movement can be used, such as a metallic frame.

Claims

1. An electric rocking chair (20) comprising a chair (22) mounted on a support base (24) in combination with means of electric actuator;

said support base containing a front inclined face (28) and a rear inclined face (28′

) outwardly directed and respectively disposed at the front side and at the rear side of said chair;

said chair containing on the underside means of displacement to be moved along each of both said inclined faces;

front means of displacement to be moved along said front inclined face, and rear means of displacement along said rear inclined face;

said means of electric actuator containing a threaded rod (36) acting on both said means of displacement and moving them along their corresponding inclined face on a see saw movement in order that when said front means of displacement is going down on said front inclined face, said rear means of displacement is going up along the rear inclined face, and when said front means of displacement is going up on said front inclined face, said rear means of displacement is going down along the rear inclined face;

thereby causing a rocking movement of said seat along said support base, said threaded rod is driven by an electric motor (50).

2. The electric rocking chair of claim 1 wherein a transversal cut-out of said support base has a trapezoidal shape.

3. The electric rocking chair of claim 1 wherein said means of displacement are means of wheels rolling along said inclined faces.

4. The electric rocking chair of claim 1 wherein said means of displacement are slide profiles.

5. The electric rocking chair of claim 1 wherein said means of displacement are linear ball bearing guide.

6. The electric rocking chair of claims 3 and 4 wherein said means of displacement are maintained by means of metallic frame (34) for avoiding the failure of the chair, therefore said threaded rod act on said means of frame, and said frame is rolling along said inclined faces of said support base by means of displacement attached on.

7. The electric rocking chair of claims 3 and 4 wherein said inclined faces comprising means of linear guides where on roll said means of wheels, said linear guides are made on a material facilitating the displacement of said means of displacement.

8. The electric rocking chair of claim 1 wherein a supplemental electric actuator dispositive (38) is used to lengthen the leg-rest (52).

9. The electric rocking chair of claim 1 wherein said electric motor (50) is coupled with a worm gear reducing the rotational speed between 2 rpm to 20 rpm and driving said electric actuator device.

10. The electric rocking chair of claim 1 wherein said electric motor is coupled with a hypoid gear reducing the rotational speed between 2 rpm to 20 rpm and driving said electric actuator device.

11. The electric rocking chair of claim 1 wherein said electric motor is coupled with a planetary gear reducing the rotational speed between 2 rpm to 20 rpm and driving said electric actuator device.

12. The electric rocking chair of claims 6, 7 and 8 wherein said electric motor is a step motor.

13. The electric rocking chair of claims 6, 7 and 8 wherein said electric motor is a servo-motor.

14. The electric rocking chair of claims 6, 7 and 8 wherein said electric motor is a brushless motor.

15. The electric rocking chair of claim 1 wherein the rocking is controlled by a remote control allowing to choose a preferred rocking speed.

16. The electric rocking chair of claim 1 wherein said means of electric actuator is a linear electric actuator device, said linear electric actuator device controls the speed acceleration and the speed deceleration of the in and out movement of the rocking chair.
