States arent 3,019,052 AUTMATIC ROCKER AND GLIDER Antoni Zawatlzki, 43 B St., Buffalo, N.Y. Filed July 3, 1958, Ser. No. 746,382 1 Claim. (Cl. 297-260) This invention relates to rocking chairs, and more particularly to a rocking chair provided with motor means for oscillating same.

A main object of the invention is to provide a novel and improved rocking chair or glider which is simple in construction, which involves relatively inexpensive parts, and which is provided with means for mechanically rocking the chair or glider when desired.

A further object of the invention is to provide an improved rocking chair provided with motor means for oscillating same, said rocking chair being neat in appearance, being smooth in operation, and involving a minimum amount of maintenance to keep it in working order.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

FIGURE l is a side elevational view, partly in vertical cross section, of an improved motorized rocking chair constructed in accordance with the present invention.

FIGURE 2 is a rear end elevational view of the rocking chair of FIGURE l.

FIGURE 3 is an enlarged horizontal cross sectional view taken on the line 3--3 of FIGURE 1.

FIGURE 4 is an enlarged vertical cross sectional detail view taken on line 4--4 of FIGURE 2.

Referring to the drawings, the improved motorized rocking chair is designated generally at 11 and comprises a base member 12 including the upwardly convex supporting surfaces 13. Designated at 14 is a chair member having the downwardly convex arcuate bottom members 15 which are supportingly engaged on the upwardly convex base elements 13 and which are retained thereon by respective pairs of fastening springs 16, 16 connecting the chair member to the respective members 13, 13 at the opposite sides of the chair member inwardly adjacent to the arcuate rocker bars 15, 15.

The members 13, 13 are rigidly connected by a transverse bar member 17, and mounted on said transverse bar member is a horizontally arranged electric motor 18 whose shaft is drivingly coupled through a gear box 19 to a drive shaft 20 journaled in a sleeve-like housing portion 21 overlying the transverse bar member 17. Secured on the shaft 20 is a first clutch sleeve 23 provided with the spaced teeth 24.

Designated at 25 is a crank disc member which is rotatably and slidably engaged on the shaft 20 and which is rigidly connected to a second clutch member 26 which is disposed adjacent to the first clutch sleeve 23 and which is provided with spaced clutch teeth 27 receivable between the clutch teeth 24 of the first clutch member 23. The disc 25 is connected to the clutch member 26 by a sleeve portion 28 which is formed with an annular groove 29. Designated at 30 is a clutch shifting lever which is pivoted at 31 to a bracket 32 secured to the cross bar 17, the lever 30 being formed with a yoke portion 33 rotatably engaging in the groove 29, whereby the clutch member 26 is movable into and out of locking engagement with the clutch member 2.3 responsive to rotation of the lever 30.

Secured on the end of the shaft 20 is a stop washer 35 to limit the outward movement of the crank disc 25 which occurs when the lever 0 is rotated clockwise, as viewed in FIGURE 3.

Connected to the end portion of the lever 30 opposite the yoke 33 is the end of a fiexible Bowden cable 38 which extends through its flexible sheath 39 and terminates in an operating knob 40 located adjacent the forward portion of one of the arms 41 of the rocking chair body 14. As shown in FIGURE 1, a bracket 42 is employed to support the sheath 39 in the position illustrated.

A control switch 43 is mounted beneath the top portion of the arm 41, the switch being wired in circuit with motor 18 and an electric power supply cord, not shown, whereby the motor is energized when switch 43 is closed.

As will be readily apparent, when the operating knob 40 is pulled upwardly, the cable 38 rotates the lever 30 clockwise, as viewed in FIGURE 3, causing clutch member 26 to disengage from clutch member 23, thereby disconnecting the crank shaft 25 from the drive shaft 20; Conversely, the disc 25 may be coupled to the drive shaft 20 by pushing the control knob 40 downwardly.

Secured on the peripheral portion of the crank disc 25 is a post member 44, and rotatably connected to the end of the post member 44 is a crank arm 45, a suitable ball bearing unit 46 being provided at the pivotal connection between crank arm 45 and post member 44, as shown in FIGURE 3. Rigidly connected to the lower portion of the back 48 of the seat member 14 is an outwardly projecting post member 47. Rotatably mounted on the reduced end portion 49 of post member 47 is a bearing block 50, which is rotatable around the axis of the post memyber 47. The bearing block 50 is received in a rectangular notch 51 formed in the top end of the crank arm 45 and is pivotally connected to said crank arm by a transverse pin 52 extending through the upper portions of the beting block 50 and the crank arm 45. Thus, the crank arm 45 is freely rotatable around the axis of the transverse connecting pin 52, and is also rotatable with the bearing block 50 around the axis of the post member 47. Thus, a universal connection is provided between the crank arm 45 and the lower portion 48 of the chair body 14.

In operation, when the motor 18 is energized by closing switch 43, with the clutch segments 23 and 26 in interengaged positions, the driving shaft 20 transmits torque to the crank disc 25 causing said disc to rotate, whereby the crank arm 45 transmits rocking force to the chair body 14. This action continues as long as the motor 18 is energized. To temporarily discontinue the rocking action, it is merely necessary to pull the control knob 40 upwardly, which rotates the lever 30 in a clockwise direction, as viewed in FIGURE 3, disengaging clutch member 26 from clutch member 23, whereby torque from motor 20 is no longer delivered to the crank disc 25.

To deenergize the motor 18 it is merely necessary to open the switch 43, which may be readily accomplished by a person occupying the chair.

While a specific embodiment of an improved motorized rocking chair or glider has been disclosed in the foregoing description, it will be understood that various: modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claim.

What is claimed is:

In a rocking chair assembly of the type comprising an arcuate base and a rocking chair member movably mounted thereon and provided with a vertical rotary driving member rotating in a vertical plane substantially transverse to said base, means defining a driving connection between an exposed portion of the rocking chair member and said vertical rotary driving member, comprising a crank arm pivoted to and extending upwardly from, said rotary driving member, said crank arm being formed at its top end with a notch defining a pair of spaced upwardly extending parallel arms, a block member disposed between said arms with the major portion thereof housed in said notch, a transverse pin extending through the upper portion o'f said block member and the upper portions of Said arms, pivotally connecting the upper portion of said block member to said arms so that the block member is swingable in said notch around a transverse horizontal axis, a post member rotatably connected to said block 5 member at a point spaced below said last-named transverse horizontal axis and being journaled to said block member on an axis contained in a Vertical plane extending perpendicular to the plane of the block member, and means connecting said post member to the exposed portion of 10 the rocking chair member.
