SHEET 2 BF 2 ELECTRICALLY ROCKED CRIB This invention relates generally to cribs for infants and children.

It is well known to most parents that uponoccassion a child or infant must be rocked to sleep. This can be a time consuming chore to a parent who has numerous other tasks awaiting to be done. Likewise, it can be an objectionable chore during a middle of anight when the parent needs his own sleep. This situation accordingly is in want of an improvement.

Accordingly, it is a principle object of the present invention to provide a crib that is automatically, electrically rocked so to free the parent from doing it.

Another object is to provide an electrically rocked crib which can be connected to a timer mechanism so to automatically shut off the rocking mechanism after a specified length of time so that the parent is not disturbed so to do the same.

Still another object is to provide an electrically rocked crib in which the operating mechanism is readily adaptable for rocking a cradle.

Still a further object is to provide an electrically rocked crib in which the operating mechanism is readily adaptable to be made for small toy cribs and cradles, and wherein a built-in dry cell battery provides the electric power to drive the toy mechanism.

Other objects are to provide a crib that rocks electrically and which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawings wherein:

FIG. 1 is a perspective view of one form of the invention.

FIG. 2 is a side cross sectional view of a modified design thereof.

FlG. 3 is a cross sectional view on line 3-3 of FIG. 2.

FIG. 4 is a side view of still another modified design of the invention.

FIG. 5 is a cross sectional view on line 55 of FIG. 4.

FIG. 6 is a fragmentary perspective view thereof.

Referring now to the drawing in detail, and more particularly to FIG. 1 thereof at this time, the reference numeral 10 represents an electrically rocked crib according to the present invention wherein there is a headboard 11 and footboard l2 interconnected by side rails 13 so to enclose a safe sleeping area for a infant or child.

in the present invention, a channel shaped track 14 is affixed to the headboard and footboard, so that rollers 15 attached to a spring frame 16 can travel on the tracks, thus permitting the spring frame to move sidewardly within the sleeping area. The spring frame 16 supports a mattress, not shown, thereupon.

Below the spring frame 16, there is a longitudinally extending beam 17 stationarily secured at its opposite ends to the headboard and footboard by means of screws 18. Upon a center of the beams, an electric motor 19 is mounted, the motor being integral with a speed reducer and being operated by an electric extension cord 20 and plug 21 which can be plugged into a household electric outlet socket. A motor shaft 22, driven by the motor, has a plate 23 mounted thereupon, and one end of a connecting rod 24 is mounted freely pivotable on a pin 25 that is eccentrically positioned on the plate 23. An opposite end of the connecting rod 24 is mounted freely pivotable on a pin 26 rigidly secured to a lug 27 that is affixed on the spring frame.

Accordingly in operative use, when the motor is turned on, the speed reducer rotates the motor shaft and plate 23 approximately twelve turns per minute, thus causing motion transmitted through the connecting rod to reciprocally slide the spring frame horizontally back and forth so that it travels along the tracks 14. Thus a child in the crib can be automatically rocked to sleep.

A timer, not shown, can be included so to cut the electric circuit to the motor at a set time so that the rocking automatically stops, thus freeing a person from attending thereto.

As shown in FIGS. 2 and 3, the present invention is adaptable for incorporating into a toy crib 28 wherein a rigid bedstead 29 is comprised of headboard 30 and footboard 31 being interconnected by side rails 32. A pair of side walls 33 are each at their upper end pivotable about nails 34 secured in the headboard and footboard, so that the side walls are free to swing. A lower end of the sidewalls are connected freely pivotable by nails 35 to a horizontal board 36 upon which a doll may be reclined.

A cross beam 37 rigidly secured between side rails 32 supports a stationary electric motor 38 together with a dry cell battery and switch, not shown, and which are in a series electric circuit. An output shaft 39 has a fixed plate 40 with eccentric pin 41 connected to one end of a connecting rod 42, the other end of the rod being connected to pin 43 on a lug 44 secured to the underside of board 36. Thus when the motor is on, the side walls 33 and board 36 rock back and forth as shown by the solid and dotted lines in FIG. 3, so a child can automatically rock her doll.

In FIGS/4, 5 and 6 another modified design 45 of the invention intended, not for toys, but for practical use on a childs real crib, includes headboard 46, footboard 47 and bars 48 mounted therebetween by crews 49. A pair of upward extending leaf springs 50 are welded at their lower ends to each of the bars 48, while the upper ends of the leaf springs are welded to a spring frame 51.

Cross braces 52 welded to bars 48 support electric motor 53 stationarily. Connecting rod 54 eccentrically attached at motor end while other end is connected to a lug 55 mounted on crib spring 51 by brace member 57, as above described, carries a wheel 55 at its other end that rides in a track 56 of a curved metal bar 57 that is integral with the spring frame.

Thus various forms of the invention have been indicated.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.

What is claimed is as follows:

1. In an electrically rocked crib, the combination of a stationary bed stead comprised of a headboard and footboard interconnected by side rails therebetween, so to form an enclosure around a central area containing a horizontal member upon which a mattress can be supported, and means whereby said horizontal member is reciprocally sidewardly moved, said means comprising a stationarily mounted electric motor on said bedstead, a motor shaft of said motor having a plate secured thereto, an eccentric pin on said plate being connected pivotally to one end of a connecting rod which at its other end moves said horizontal member, and means whereby said horizontal member travels an arcuate path that accordingly includes a vertical displacement as well as sideward movement.

2. The combination as set forth in claim 1 wherein said horizontal member comprises a board pivotally supported at lower edges of a pair of parallel, spaced apart side walls of said crib, said side walls being pivotally supported at their upper ends between said head- 4 board and footboard, so that said is upwardly.

welded to downward leaf springs secured attheir lower ends upon stationary bars between said headboard and footboard so said spring frame sways on said leaf springs by said means, so that saidvertical displacement is downwardly, and said connecting rod opposite end is connected to a lug mounted on said horizontal member by a brace member, and which carries a wheel at its other end that rides in a track, of a curved metal i barintegral ,with said horizontal member.
