ABSTRACT:
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.
