Abstract
A swing assembly suitable for children ages new borne through 12 months has a seat member that surrounds the child, and a disk-shaped base with support legs extending upwardly therefrom. The width of the base exceeds the vertical extent of the swing assembly making it extremely stable. The base includes a stationary base that supports a rotational base to permit turning throughout 360° about a vertical axis. The swing may be oscillated by manual and/or mechanized members. The dimensions of the swing are such that it can be easily maneuvered around, moved about and transported to other locations.
Description




BACKGROUND AND SUMMARY OF THE INVENTION




The present invention is directed to a baby swing. More particularly, the present invention is directed to a low-profile swing that is safe for infants, ages new born to twelve months.




In the past several years, numerous law suits arising from infant injuries and fatalities have resulted in recalls of conventional baby swings and reduced the number of manufacturers of such swings from about a dozen to only a few. Indeed, the financial burden of those burgeoning law suits threatens to force the remaining manufacturers to discontinue production of their swing product lines.




Even apart from the threat of injuries, conventional baby swings had numerous other problems. The long skinny legs that made the swing so unstable, also made it difficult to maneuver, a risk for tripping passers by, and problematic for taking along (i.e., this swing design did not fit easily into a car). Further, the swing could not easily, nor safely, be moved from place to place while the baby was seated therein. Therefore, movement of the swing during use would require two persons: one to hold the baby, one to move the swing.




Coupled with the safety issues associated with walkers and bouncers, there are very few, if any, devices that parents can safely use to occupy their children. Further, most all of these devices are unsuitable for use with new born children or any child younger than 3-4 months old whose neck is incapable of supporting the weight of its own head.




The present invention overcomes the problems with these prior art baby swings. The present invention comprises a low-profile swing for infants including a base member, support legs extending upward from the base member, a seat for an infant rotationally supported by the legs, and means for oscillating the seat relative to the base and the legs, allowing the infant to be safely swung without fear of tipping. The base is a disk-shaped element whose maximum lateral dimension exceeds the maximum vertical extent of the support legs. This configuration provides an extremely stable configuration that cannot readily be tipped over. The seat completely surrounds the child while supporting the infant in a semi-reclined position and is, therefore, suitable for infants from new born through 12 months of age. Optionally, the seat may be removed from the support legs and double as a layette or car seat. The base member includes a stationary base element and a rotational base element so that the orientation of the swing may be readily changed to provide the infant with a change of scenery. Further, the stationary base may be provided with casters so that the swing may be easily moved without the necessity of removing the child. Since the child's legs do not extend outside the confines of the seat member, the seat may be mounted within a few inches of the base enhancing the stability of the swing assembly. Lastly, the relatively compact construction and light weight of this swing enable a mom to easily pick up the swing to transport it to another room or load it into a car to enable its use during a visit.




Various other features, advantages and characteristics of the present invention will become apparent to one of ordinary skill in the art after a reading of the following specification.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT(S)




A first preferred embodiment of the low-profile swing assembly of the present invention is shown in

FIGS. 1-5

generally at


20


. Low-profile swing assembly


20


includes a disk-shaped base member


22


and two legs


30


,


32


which extend generally vertically from an upper face thereof. Base member


22


includes a stationary base


25


and a rotational base


26


supported thereon by wheels


27


that are received in molded recesses


28


(FIG.


6


). Rotational base


26


has a stepped configuration, center portion


23


being raised to provide room for the upper halves of wheels


27


. Rotational base


26


can be turned throughout a 360° arc relative to stationary base


25


to provide the infant with a change of visibility (both what it sees and where it can be seen from). Casters


29


are preferably provided beneath stationary base


25


(

FIGS. 2-4

) to facilitate its movement from place to place, but may be omitted to save manufacturing cost without significantly impacting the utility of the device. Base member


22


is extremely stable: even with a 200 lb man standing on the edge of base


22


, it will not tip over.




As shown in

FIGS. 1 and 1A

, legs


30


,


32


have a cruciform cross section throughout most of their length, although other configurations (such as cylindrical with laterally projecting braces for engaging the base) can provide adequate horizontal and vertical stability. In this first embodiment, legs


30


,


32


have an integral circular base


34


that may be attached to rotational base


26


in any conventional manner. Upper reach


36


of leg


30


may be equipped with a generally L-shaped notch


38


to permit stub axle


42


of seat member


40


to be readily removed so seat member


40


may serve a secondary function as a car seat or layette. Knob


39


on the end of stub axle


42


and a rib


41


on stub axle


42


capture the upper reach


36


of leg


30


and prevent relative lateral movement of seat member


40


relative to leg


30


. The downward slope of L-shaped notch


38


will prevent undesired upward movement of stub axle


42


and only intentional lifting by the swing operator will disengage the stub axle


42


from notch


38


. Stub axle


43


is received in sleeve


62


of oscillating motor


60


and secured thereto by set screw


63


(

FIG. 5

) that may engage in a recess in, or on a flat side of, (not shown) stub axle


43


. Sleeve


62


extends through a bearing positioned in an upper reach


37


of leg


32


. To remove seat member


40


from legs


30


,


32


, set screw


63


is loosened, stub axle


42


lifted clear of notch


38


and stub axle


43


removed from sleeve


62


. To reinstall seat member


40


, the process is reversed. It will be understood that manufacturing costs may again be shaved by eliminating this feature and simply rotationally securing both of stub axles


42


,


43


to an upper portion of legs


30


,


32


, respectively.




Seat member


40


comprises an outer molded plastic shell


44


with a padded inner liner


46


. A pair of arms


48


are attached to sides


50


,


52


of shell


44


at


54


and have stub axles


39


extending outwardly therefrom The length of arms


48


between attachment points


54


and stub axles


42


,


43


constitutes the radius arm for the oscillation of the swing seat member


40


. It can be seen that this radius arm measured in inches rather than feet, will result in a gentle swinging motion. Further, since seat member


40


supports the infant in a semi-reclined position, the child need not be old enough to support the weight of its head and low-profile swing


20


can safely be used with children from new borne infants up through 12 months of age. Further, since the child's feet do not extend below the seat member, the swing need be no more than a few inches from the base. Such a low profile is extremely safe, tilt proof, and unachievable with conventional designs in which feet dangle below the seat. If swing assembly


20


is used with a new borne, cylindrical pillows, or the like, may be used to take up space along the sides and prevent the small baby from becoming skewed in seat member


40


.




While motor


60


can be utilized to provide oscillatory motion, as an alternative or, in addition, a tether cord


64


can be attached to a rear portion


66


of seat member


40


and a handle


68


secured to the loose end thereof. The use of a musical device associated with motor


60


, or separately therefrom, is within the scope of this disclosure. Further, a bar


70


extending between arms


48


can suspend a block


72


, keys (not shown), or the like, for infants two months old and above to play with. The ends


74


of bar


70


are received in openings


49


in arms


48


. A stop ring on a first end


74


and a spring engaging the other (neither shown) can be employed to properly position and retain bar


70


in a desired location.




The low-profile swing assembly


20


of the present invention has a base


22


that has a maximum dimension that exceeds the upward reach of support arms


30


,


32


. This geometry provides an extremely stable configuration that cannot be easily tipped. Further, the arms


48


that define the radius of swinging are comparatively short (vis a vis other swings) and hence, the swinging motion is very gentle. Also, the child's feet do not extend beyond the confines of the swing enabling a lower suspension than is possible with other designs. Lastly, the seat assembly


40


retains the infant in a semi-reclined position so, unlike the swings of the prior art, swing assembly


20


can be safely used with infants from new born up to 12 months of age. Low-profile swing assembly


20


is compact and light weight. It can easily be moved from place-to-place and picked up and placed in the trunk or back seat of a car to allow it to be transported to a friend's house so it may be utilized during a visit.




Various changes, alternatives and modifications will become apparent to one of ordinary skill in the art following a reading of the foregoing specification. It is intended that any such changes, alternatives and modifications as fall within the scope of the appended claims be considered part of the present invention.
