Abstract
An open top swing which includes a frame and mounting housings. A swing assembly depends from the pivot pins and includes a pair of spaced legs to which a swing is releasably attached for moving the swing closer to or away from the pivot pins to permit a change in the swing speed and the distance of the arcuate path that the swing will travel.
Description




BACKGROUND OF THE INVENTION




The invention disclosed herein relates generally to an open top infant swing, and, more particularly, to an improved infant swing having a system for adjusting the height of the swing seat.




DESCRIPTION OF THE PRIOR ART




Open top infant swings are presently available on the market. The devices generally include a base or frame member which is disposed on the ground surface. A swing assembly is connected to and depends from the frame, the swing assembly being adapted to pivot relative to the frame assembly, the desired movement being generated either manually or by means of a drive motor.




While such swing assemblies are generally satisfactory, certain disadvantages exist. It has been found that, in some instances, when an infant is placed in the swing assembly, a mother or operator is concerned because the drive motor will not only cause the swing to travel over too great an arc, but the swing speed is too rapid for the particular child.




Moreover, it sometimes is desired to position the infant who is located in the swing further off the ground so that the child is positioned closer to a mother for feeding and the mother does not have to bend over as far to place the child in the seat. Accordingly, it is desired to have an open top swing with some means for selecting the swing speed and arch of swing travel. It also is desired to have a swing device where the position of the seat relative to the frame can be adjusted along a vertical axis.




SUMMARY OF THE INVENTION




Applicant's invention serves to obviate the above-described disadvantages while at the same time achieving the particular desires sought for an infant swing assembly.




Briefly, applicant's invention, as disclosed and claimed herein, is directed to an open top swing having a swing assembly which depends from a frame assembly with the swing seat being adapted to rotate relative to the swing frame. The swing assembly preferably comprises a U-shaped member which includes a pair of legs each of which depends from a pivot pin located in a mounting housing. The pivot pins may be rotated either manually or by means of a conventional drive motor attached to a pivot pin.




A clamp assembly is connected to each side of a swing seat. The assemblies, in turn, are adjustably coupled to the seat support leg of the U-shaped member whereby the seat can be selectively raised or lowered to a desired position along the length of the legs.




When a child is quite young and a parent wishes the seat to travel to a short arc at a relatively low speed, the seat is raised on the leg members to a position contiguous to the pivot pins. As a child grows, however, and it is desired to increase the arcuate path of travel of the swing as well as the swing speed, the seat is adjusted to a position on the legs located further away from the pivot pins.

,


50


thereby locking the clamp assemblies to the seat support legs. By pushing in on button


72


of the respective clamp assemblies, button members


70


are urged inwardly in the direction indicated by arrow “A” in

FIG. 4

whereby detent


76


is removed from opening


79


and clamp assemblies


60


and


61


are in an unlocked position relative to the seat support legs. Seat


52


then is capable of being moved up or down along the length of legs


39


,


50


to another opening


79


. Button


72


then is released whereby button member


70


returns to its normal biased position and detent


76


is positioned in a desired opening


79


whereby infant seat


52


is positioned in a desired position.




It will be appreciated that as the infant seat is moved upward and closed to the pivot pins, seat


52


, upon actuation of drive motor


42


, will travel an arcuate distance which is less than the arcuate distance travelled when swing seat


52


is located a greater distance away from the pivot pins. Moreover, when the seat is positioned close to pivot pin


37


, the swing speed is slower as opposed to the speed at which the swing seat travels when it is located contiguous to seat support base


51


. As a result, a mother, parent or other operator is able to adjust both the arcuate swing distance an infant will travel as well as the speed of seat travel. Moreover, if it is desired to feed a child in the open swing of the present invention, the seat can be adjusted to be locked in a fixed position contiguous to pivot pin


37


whereby access to the child can be achieved relatively easily.




It is appreciated that the various components of the device of the present invention can be made using any suitable plastic or metal materials utilized with open top swings presently available. Similarly, it is appreciated that other clamp locking systems can be utilized to adjust the location of the swing seat relative to the pivot pins.




It is also appreciated that while two swing support legs have been utilized, a swing assembly could, if desired, utilize one seat support leg which would extend from one of the mounting housings.




While the present invention has been described in connection with a single embodiment, it will be understood to those skilled in the art that many changes and modifications may be made without departing from the true spirit and scope of the invention. It is therefore intended by the appended claims to cover all such changes and modifications which come within the true spirit and scope of the invention.
