Description:
This invention relates broadly to apparatus for producing orbital or rotational movement concurrently with the creation of rocking motion and the operation of a music producer, and in its more specific aspects it relates to such apparatus which has been especially designed to provide the orbital and rocking motions to a seat, enclosure, platform or the like, which is adapted to contain an infant in order to produce amusement and quiet for periods of time; and the nature and objects of the invention will be readily recognized and understood by those skilled in the arts to which it relates in the light of the following explanation and detailed description of the accompanying drawings illustrating what I at present believe to be preferred embodiments or mechanical expressions of my invention from among various other forms, arrangements, combinations and constructions, of which the invention is capable within the spirit and scope thereof.
One of the prime purposes of my invention is to provide an apparatus for quieting, soothing and amusing infants up to the age of approximately 40 weeks. Any mother will appreciate that it is highly desirable to be free of an infant in this approximate age bracket for periods of time to release her for other chores, rest, or the like. The apparatus of this invention has been designed specifically for the purpose of quieting, soothing and keeping an infant amused for periods of time so that the person in charge of the infant may be relieved of the cares and noises associated with minding an infant. The structural concept which I have evolved comprises generally an enclosure in which the infant may be disposed, and includes means for producing rotational motion to the enclosure, and also for providing rocking motion thereto. The apparatus further includes means operable by the main orbiting means to produce music. It will be recognized, and experiments which I have carried on indicate, that the parent, or person minding the baby, will be free for approximately 30 minutes when the infant is positioned within the enclosure and is subjected to the rotational and rocking motion thereof and soothed by the music.
I have so constructed the means which generates the rocking motion so that the enclosure is rocked approximately 10 times for each complete revolution, or orbit, of the enclosure. It is preferable, though not necessary, that the rocking stroke which is applied to the enclosure is on the order of three quarters of an inch, and I have discovered, through experimentation, that this stroke length appears to be adequate for the infant. I have also arranged my operational mechanism so that the enclosure is rotated at approximately 3 rpm, 30 rocks per minute, 1 second up and 1 second down.
One of the significant characteristics of my invention resides in the construction, operation and arrangement whereby the music may be operated alone, the orbital movement generated alone, or the rocking motion alone, or all three operated concurrently, or any two operated concurrently without the other. The advantageous results of my unique arrangement will be readily appreciated. The music alone may function to soothe and quiet the infant whether or not it is in the enclosure, and either rocking motion or combined with the orbital motion, or the orbital motion alone may achieve the desired results.
It is within my contemplation to adapt this apparatus to a variety of uses and such adaptations will still fall within the spirit and scope of the invention. As one example, from among many, the enclosure may be removed and a platform, table or the like substituted therefor which would be caused to rotate and/or rock by the motive power. Displays, or the like, could be mounted on the table or platform.
In achieving my purposes, I have not sacrificed simplicity of operation and control, relatively low costs of manufacture and assembly, ease of operation and long life under normal operating conditions, and also the safety of the infant.
With the foregoing general objects, features and results in view, as well as certain others which will be apparent from the following explanation, the invention consists in certain novel features in design, construction, mounting and combination of elements, as will be more fully and particularly referred to and specified hereinafter.

In the accompaning drawings, I have used the numeral 1 to designate, in its entirety, the enclosure or infant seat, the numeral 3 to designate, in its entirety, the mechanism producing the rocking motion in the enclosure, the numeral 5 the housing or rotatable member, in which the actuating mechanism designated generally by the numeral 7 is disposed, and the numeral 9 to designate the electric motor or other power means for operating the actuating mechanism. I have used the numeral 11 to generally designate the music producing means of the apparatus.
The apparatus is operatively mounted on any suitable type of base 13, preferably of generally circular configuration, the base being provided about its perimeter with an upstanding annular member 15 having an annular groove or track 17 provided in the top surface thereof. The annular member 15 may be epoxied, or otherwise caused to adhere to the base. The casing, or rotatable member, which I have generally designated by the numeral 5, is mounted on bearings 19 which travel in the track 17 provided in the annular member 15. The housing 5 is preferably of generally circular configuration and is formed with a top portion 21 from which downwardly depends an annular apron-like portion 23, having a flat annular base 25 which rests and rides on the bearing elements 19. The apron 23 is provided with an interior flange 24 from which radially outwardly extends a flange, rim, or the like 26. A radially inwardly extending flange, rim or the like 28 is provided on annular member 15 and is received in the area between flanges 24 and 26 to maintain the housing against lateral movement on annular member 15 as the housing rotates relative thereto. Projecting upwardly from the housing is a tubular, sleeve-like member 27, which as will be explained operatively houses a part of the rocking mechanism causing the enclosure to rock.
A rotary shaft 29 extends upwardly from, and is driven by the electric motor 9, and is splined or otherwise affixed to gear 31 which will, of course, be rotated by the shaft 29 when it is operational. A cap nut 30 is threaded on the upper end of the rotary shaft 29, as will be clear from the drawings. The gear 31, which constitutes the driving gear of a gear train to be described, is provided with a set of circumferentially spaced bearings 33 upon which rides a driven gear 35, the drive shaft 29 extending freely through and beyond driven gear 35. Consideration of the drawings illustrates clearly that the diameters of bearings 33 are such that gear 35 will be spaced from gear 31. Gears 31 and 35 are formed with perimetric teeth 37 and 39, respectively. An upstanding sleeve or neck 41 is fixed to the central zone of gear 35 for rotation therewith. The rotary shaft 29 extends freely through the sleeve or neck 41. The upstanding sleeve or neck 41 is provided with a plurality of circumferentially spaced slots 42 therein, in this instance four. The slots 42 open through the periphery of the sleeve or neck. The purpose of these slots will become clear as this description proceeds.
The gear train further includes a pair of pinions 45 and 47 which are positioned between gears 31 and 35, the teeth of the pinions being in mesh with the teeth 37 and 39 of gears 31 and 35. Thus, the pinions are driven by gear 31, and in turn gear 35 is driven by the pinions. Pinion 45 is provided with a shaft 49 which is rotated thereby and extends therefrom while pinion 47 is provided with a shaft 51 which is rotated thereby and extends therefrom.
I shall term shaft 49 the rocking mechanism actuating shaft, and the shaft 51 the winding shaft for the music producing apparatus 11.
Pinion 47 and its shaft 51 winds the music producing apparatus spring which disconnects automatically when it is wound, and rewinds automatically when it is almost unwound, all as is well known in the music box winding discipline.
I have evolved a simple and easily producible mechanism, in the nature of a positive clutch, for connecting and disconnecting the housing or rotatable member 5 from the means for causing rotation thereof. This mechanism comprises a rigid rod 32 which slidably extends through the apron 23, as at 34. The rod 32 extends into a cavity 36, which is provided in the apron 23, and one end of the rod is pivotally fixed as at 38 to an end of an operating lever 40 which is pivotally mounted, as at 42, to the apron. The rod extends inwardly and upwardly within the housing and extends into and is moveably supported by a bracket, tube, or the like, 44. The bracket, tube or the like is fixed, in any suitable manner to housing 21. I provide a spring biased rod or plunger 46, the inner end of which is spaced from the complementary end of the rod 32, and a biasing spring 48 is operatively disposed between and connected to the two adjacent ends of the rods 32 and 46. The outer end of the rod or plunger 42 is in alingment with the slots 42 which are provided in the sleeve or neck 41. It will now be apparent that by actuating the lever 40 downwardly, in the driection of the arrow in FIG. 2, the rod 32 will be moved toward the plunger 46 to compress the spring 48 and move the plunger 46 toward the neck 41 and into one of the slots 42 as the neck 41 is rotated. This clutching action will cause rotation of the housing 5 since the rods 32 and 36 are disposed within bracket 44. Thus, the enclosure 1 will be caused to rotate. To stop rotation of the enclosure and the housing the lever 40 is moved upwardly into the position illustrated in FIG. 2 so that the plunger 46 under the action of the spring 48 will be retracted from its operative position in a slot.
It is to be understood that the above means for connecting and disconnecting the housing from the rotating mechanism is merely by way of example and other means may be employed, and still fall within the spirit and scope of this invention.
It is to be further recognized that when the motor 9 is energized the gear 35, through the gear train, will be constantly rotating as well as the rocking mechanism shaft 49, and that the housing will be rotated or not rotated according to the position of the clutching mechanism. Thus, as will be explained, the rocking mechanism may be actuated to cause rocking of the enclosure whether or not the housing is being rotated.
The shaft 49, which comprises the actuating means for the rocking mechanism and is rotated at all times when the motor 9 is energized, rotatively extends through a shaft guide bracket 67 and fixedly mounts on its end a spur gear 69 which is in mesh with a pinion 71 which is rotatively mounted on any suitable type of axle or the like 72. The pinion 71 is fixed to a cam 73 having a peripheral cam track 75. The cam track provides a smooth three-quarters inch rise and in FIG. 2 of the drawings is illustrated at the bottom of its travel. Extending through the sleeve or mast element 27 is a rocker stem 77, such stem extends through the top of sleeve 27 and is provided with an inclined disc-like head 79 fixed on the outer or upper end thereof. The rocker stem extends through an elongated guide bracket 81 and in operative rocking position is in vertical alignment with the cam track 75 of the cam 73. When the rocking mechanism is in operative condition, the lower end of the rocker stem 77 will ride on the cam track and will be reciprocated thereby, the uppermost position being shown in dotted lines in FIG. 2. The length of the rocking stroke is the same as the length of the rocker stem which extends beyond the upper end of the mast 27 when the stem is in full uppermost position.
The upper end of the rocker stem 77 extends into a concave depression in the bottom of the enclosure 1 and the head 79 is seated in a well 83 provided by the enclosure. It will be observed that the diameter of the well 83 is greater than the diameter of the disc or head 79 so that sufficient area for play or sliding movement of disc 79 in the well is provided. It will be appreciated that this play or movement is necessary as a result of the reciprocal motion of the stem 77 and disc 79 to produce the desired rocking motion in the enclosure, or the like, 1.
As I have explained above, it is desirable to provide means for stopping the reciprocation of the rocker stem 77 to stop rocking motion in the enclosure 1 even though the motor 9 is operating to actuate shaft 49, gear 69 and 71 and the cam 73. This means for preventing reciprocation of the rocker stem 77 while shaft 49 is operating functions in a manner to move and hold the rocker stem 77 in position laterally of the cam track so that the rocker arm is unaffected thereby.
As one example, from among many which may be employed to stop the reciprocation of the rocker stem 77 and the rocking of the enclosure 1, or the like, I have provided an operating handle or knob 93 which is rotatably mounted on a shaft 95 which extends through a thickened portion 97 of the mast, the inner end of the shaft being pivotally fixed as at 99 to a block 101 which is slidably fixed to the stem 77. Positioned between the block 101 and the thickened portion 97 is a compression spring 103 which surrounds the shaft 95. The operating knob 93 is provided with a pair of diametrically opposed locking lugs 105 which extend inwardly therefrom toward the thickened portion of the mast. The thickened portion 97 of the mast is formed with two spaced apart lug holes 107. For a purpose which will become apparent, the lug holes 107 are spaced apart the same distance as are the locking lugs 105 so that in certain rotative position of the operating knob 93 the locking lugs will be aligned with and received in the locking holes.
The cam 73 is provided with a safety lip, or flange, 109. This safety lip extends radially outwardly from the inner edge of the cam. The safety lip is not provided at the low point of the cam track 75 but it does extend radially from the cam at all other perimetric areas thereof. The purpose of this lip and its particular formation will be described in detail hereinafter.
In FIG. 2 of the drawings, I have illustrated the rocking mechanism in operative position with the lower end of the rocker stem engaged with the cam track of the cam so that this stem will be caused to reciprocate and impart rocking motion to the enclosure. It will be appreciated that with the operating knob 93 in the position illustrated the locking lugs 105 will abut the thickened portion 97 of the mast and thereby, through the shaft 95 and block 101 will hold the stem 77 in operative position on the cam track against the biasing action of the spring 103 which is compressed when the elements are in this position illustrated in FIG. 2. The arcuate portion 111 of the elongated guide bracket 81 functions as a back up plate or member for the stem 77.
With the elements and members in the operative rocking position of FIG. 2 in order to disconnect the rocking elements so that the rocking will cease, it is merely necessary to grasp the operating knob 93 and rotate it 90° so that the locking lugs 105 will be aligned with the locking holes 107. The knob is then released and when the cam track is at its low point with the rocker stem at its lowest point the locking lugs will be drawn into the locking holes 107 under the action of the spring 103, and the rocker stem 77 will be moved laterally and free of the cam track. This lateral movement of the stem will only occur at the lowest point of the cam track since this is where there is an opening in the safety lip 109. This arrangement and construction is provided so that there will not be a sudden drop of the enclosure from a high point of the cam track. The arcuate surface 113 of elongated guide bracket 81 serves to limit the lateral movement of stem 77.
The housing 5 is provided with a fulcrum rod 115 which is fixed to the housing so that it will orbit therewith. The rod 115 extends slightly above the upper surface of the housing so that it will function as a fulcrum element for the rocking motion of enclosure 1. The bottom of the enclosure is formed with a transverse groove into which rod 115 seats. See FIG. 1.
Electric switches 117 and 119 are provided for controlling the operation of the electric motor 9 and the music producing means 11.
It will be recognized that the rocker mechanism actuating pinion 45 must not rotate at the same speed as the gear 37; if it did, it will be apparent that the rocking mechanism would not function as desired.
It is to be understood that when the term "enclosure" is used in this specification and in the claims, it is intended to refer to any member such as an enclosure, platform or the like which is rotatable and/or rockable.
