Description




BACKGROUND




1. Field of the Invention




The present invention relates generally to infant swings and more particularly to a collapsible infant swing frame.




2. Discussion of the Related Art




Infant swings are known in the art. Conventional infant swings are designed to be folded or otherwise collapsed for long term storage. However, even in the folded configuration, such swings are still relatively cumbersome and not necessarily compact. Additionally, to fold a conventional swing requires some measure of effort on the part of the user.




There are infant swings that are designed to be easily disassembled and reassembled to make them compact and portable. However, such swings typically require that each of the components of the swing be separated, increasing the likelihood that certain components will be misplaced.




Thus, there is a need for a collapsible infant swing that is easily reconfigured from a stored position to a useful position and that can be easily transported.




SUMMARY OF THE INVENTION




The present invention provides an infant swing frame having a base, and first and second support posts. Each of the support posts is pivotally coupled at a first end thereof to the base, and each of the support posts has a second end. A cross member is coupled between the support posts. The support posts and the base are reconfigurable between a first position in which the support posts are angularly spaced from the base and a second position in which the support posts are adjacent the base.




According to one aspect of the present invention, a pair swing arms are pivotally coupled to the end of a respective support post and extend downwardly from the support posts toward the base when in the first position. A seat is coupled to the lower ends of the swing arms.




These and other aspects of the present invention will become apparent from the following drawings and description.

DETAILED DESCRIPTION





FIGS. 1 through 9

illustrate one embodiment of a collapsible infant swing


100


. The collapsible infant swing


100


includes a support frame


105


that supports swing arms


250


, which in turn support a swing seat


190


.




The support frame


105


is configured to elevate the swing seat


190


above a supporting surface S. Frame


105


includes support posts


210


and a base


150


that are reconfigurable with respect to each other between a first orientation in which the support posts


210


are angularly spaced from the base


150


and a second orientation in which the support posts


210


are adjacent the base


150


.




In the illustrated embodiment the base


150


is substantially u-shaped with parallel side members


152


and front member


153


. Feet


155


can be provided on the base


150


to engage the supporting surface to inhibit the swing


100


from sliding.




Support posts


210


are coupled to, and extend upwardly from, base


150


. Each support post has a first, lower end


212


coupled to the base and a second, upper end


214


. The side members


152


and support posts


210


may be coupled to a positioning member


500


(as described in detail below). Alternatively, the support posts


210


may be coupled directly to side members


152


.




In the illustrated embodiment, a cross member


300


is coupled between support posts


210


at second end


214


disposed above seat


190


. Cross member


300


provides several functions: stability for the frame


100


; a handle for carrying the swing; support for the swing seat; a housing for the swing drive system; and a location for entertainment features. In alternative embodiments, cross member


300


can provide subsets of these functions. In the illustrated embodiment, cross member


300


includes a recess


310


sized to permit an adult user to grasp the recess and thus carry swing


100


. End caps


302


,


304


are included on cross member


300


to maintain the position of the support posts


210


and to maintain the position of swing arms


250


(as described below).




The cross member


300


includes entertainment features such as hanging toys or articles


332


and lights


330


. When an infant positioned on the swing seat


190


grasps and/or pulls one of the hanging toys


332


, lights and/or sounds may be actuated. The lights and/or sounds may be deactivated after a predetermined time or, alternatively, when the infant grasps or pulls the toy again. Alternatively, lights and sounds may be actuated by the adult user with a switch located on cross member


300


.




Swing arms


250


extend downwardly from cross member


300


towards base


150


. The swing arms


250


are driven by a drive mechanism (not illustrated) located in cross member


300


. Drive assemblies known to those skilled in the art (whether electrical or mechanical) may be used to reciprocate the swing arms


250


. A switch is provided on cross member


300


to selectively actuate the drive assembly. The swing arms each have a first, lower end


252


and a second, upper end


254


. The second end


254


is coupled within the cross member


300


and may be coupled directly to the second end


214


of support posts


210


. The first end


252


of swing arms


250


are coupled to the seat


190


.




The seat


190


is substantially elliptical or oval in plan view and includes a removable cover


180


that defines a seating surface between the support posts


210


. The seat cover


180


is coupled to a seat frame


186


either by a simple friction fit or using hook-and-loop fasteners. The seat


190


can be manufactured from fabric or similar material. Alternatively, the seat


190


may be manufactured from other flexible materials such as vinyl, molded plastic or the like. Seat


190


may include a quilted surface to provide greater comfort for the infant positioned therein and may be manufactured using multiple layers of fabric between which backing material may be accommodated. The seat includes a foot portion


192


and a back portion


194


that are pivotally coupled to the swing arms


250


, so that they may be rotated into a storage position in which they are approximately parallel. The back portion


194


and foot portion


192


, together provide a seat that is an inclined position relative to the supporting surface S. Seat


190


further includes a belt


170


to maintain an infant in position in the seat. The belt


170


includes a pocket


172


having a plush article


174


tethered thereto. The pocket provides a convenient storage area for the plush article


174


while the tether allows the infant to play with the article


174


without dropping it on the floor.




Referring now to

FIGS. 5 through 7

, the swing


100


further includes a shield


400


coupled to the seat


190


to prevent an infant occupant of the seat from extending its arms outside the seat area. The space between each support post


210


and corresponding swing arm


250


is a wedge-shape swing area A that varies with the position of swing arms


250


.

FIGS. 5

,


6


, and


7


illustrate the changing extent of swing area A when the swing is in its rest position at the bottom of the arc defining its range of motion, at the forward end of the arc, and at the back of the arc, respectively. Shield


400


is provided to prevent an infant from extending its arm into swing area A, where they might be pinched between swing arm


250


and support post


210


at the back of the arc, or otherwise interfere with the motion of the swing.




The shield


400


may be integrally coupled with seat


190


to prevent the removal of shield


400


. Likewise, it would be undesirable to couple shield


400


to the removable seat portion


180


. Shield


400


is preferably coupled in a taut configuration between swing arms


250


and seat


190


to prevent deformation of the shield


400


thereby allowing an infant to place their arm within the swing area A. The shield


400


can be manufactured from any material that provides the desired obstruction from the swing area A. In the illustrated embodiment, the shield


400


is manufactured from a mesh material that allows a parent to view the infant sitting in the seat


190


while still providing the desired protection.




As discussed above, the frame


105


is reconfigurable between a first, use position in which support posts


210


are angularly spaced from the base


105


and a second, storage or transportation position in which the support posts


210


are adjacent to base


105


. The swing


100


is illustrated in the use position in

FIGS. 1 through 7

and in the storage position in

FIGS. 8 and 9

. When the swing is in the use position, the base


105


is substantially horizontal along a ground surface, and the support posts


210


extend upwardly from the base


150


and the swing arms extended downwardly from the second ends


214


of the support posts


210


.




The angular position between the base


150


and support post


210


is such that the swing arms


250


extend downwardly above the base


150


to maintain a stable configuration of the collapsible swing


100


when in the first position. When an infant is positioned in the seat, the center of gravity of the infant and the seat


190


together is directly below the pivot point of the swing arms


250


. The pivot point of the swing arms


250


is situated between the front member


153


and the rear of the base


150


. Moreover, the extent of the side members


152


of the base


150


is great enough to prevent the swing


100


from tipping when seat


190


is at the ends of the arc through which it moves. The support posts


210


each define an acute angle with respect to the base


150


when the swing


100


is in the use position, and therefore when the frame


105


is moved to the second position in which the support arms


210


are approximately parallel to, and on the opposite side of, the base, the base


150


rotates through an angle greater than 90 degrees.




To maintain the angular spacing between the support post


210


and the side member


152


in the use position, a positioning member


500


is provided. The base post


152


is pivotally coupled to positioning member


500


about pivot point


510


. Support post


210


is fixed within a socket in positioning member


500


(as best seen in FIG.


10


). Alternatively, both the support post


210


and the base post


152


could be pivotally coupled to positioning member


500


. Positioning member


500


includes a semi-cylindrical groove


520


to nestingly receive base post


152


when the swing


100


is in the first position. A locking clip or retention member


550


is provided on positioning member


500


to maintain the base post within groove


520


when the frame


105


is in the first position. Side members


252


may be coupled to a rotatable hub


530


that is pivotally coupled to positioning member


500


.




In use, a user can move the frame


105


from the first position to the second position illustrated in

FIGS. 8 and 9

by releasing the locking clip/retention member


550


and pivoting the base


150


around pivot point


510


until the base


150


is adjacent the support posts


210


. In the position illustrated in

FIGS. 8 and 9

, the portion of the base


150


that previously engaged the ground or support surface, is adjacent to the support post


210


as illustrated. As best seen in

FIG. 9

, at least a portion of the support posts lie in a common plane with a respective ground engaging base post in both the first position and the second position.




After folding the frame


105


into the second position, the user may fold the seat


190


such that the entire collapsible swing


100


is in a planar orientation as illustrated in

FIG. 8. A

detent mechanism is provided in positioning member


500


and cooperates with side member


152


to maintain the base


150


in the storage position. A strap


540


is coupled to the seat


190


and is long enough to wrap around the swing arm


250


to maintain the seat


190


in a folded orientation when the swing


100


is in the storage position.




While particular, illustrative embodiments of the invention have been described, numerous variations and modifications exist that would not depart from the scope of the invention. For example, as described above, a pair of swing arms


250


that are coupled to cross member


300


supports the seat


190


within the frame


105


. In one alternative embodiment, illustrated in

FIG. 11

, swing


100


′ includes a pair of swing arms


250


′ that are pivotally coupled directly to support arms


210


′. The base


150


′ is pivotally coupled around positioning member


500


′.




In another alternative embodiment, illustrated in

FIG. 12

, swing


100


″ includes a single swing arm


250


″ that is pivotally coupled to cross member


300


″ such that seat


190


″ is supported within the frame


105


″ by a single pivot point. The configuration of swing arm


250


″ may be similar to the structure disclosed in U.S. Pat. Nos. 5,803,817 and 6,027,409, the disclosures of which are incorporated herein by reference in their entirety.




The positioning member


500


as described above includes a wedge-shaped member disposed between the angle formed between the support posts


210


and the side posts


252


of the base


150


to maintain their relative positions when the frame


105


is in the first position.

FIG. 13

illustrates an alternative embodiment of positioning member


500


′. In that embodiment, positioning member


500


′ includes clips


502


′ that receive the support post


210


and base post


152


to maintain the support post and base post angularly spaced from one another when the frame


105


is in the first configuration. To reconfigure the frame


105


into the storage position, one or both clips


502


′ would be disengaged from support posts


210


and/or side members


152


.





FIG. 14

illustrates a further embodiment of a positioning member


500


″ in which the positioning member


500


″ includes two collars


502


″ that receive a post


504


″ to maintain the angular position between the support post


210


″ and the base post


150


″ when the frame


105


is in the first position. To reconfigure the frame


105


into the storage position, the post


504


″ would be disengaged from the collars


502


″.




Each of the illustrated embodiments disclose a positioning member


500


,


500


′,


500


″ that acts under compressive force between the support post


210


and the base post


152


. It will be appreciated that in a further alternative embodiment, positioning member


500


would be a tensile member, such as strap extending around the pivot point


510


and connected to the outer edges of support post


210


and base post


152


to maintain the frame in the use orientation.




As described above, the frame


100


is maintained in the storage position by using a detent mechanism. Alternatively, an arrangement of straps or clips could be utilized to maintain the position of the base


150


with respect to the support posts


210


in the storage position.




Also as described above, the seat


190


is provided with a strap


540


to maintain the seat


190


in a folded orientation when the swing


100


is in the storage position. Alternatively, multiple straps may be used or an arrangement of fasteners such as hook-and-loop fasteners, snaps, etc. may be provided on opposing seat surfaces to secure the seat in a folded orientation when the swing is in the storage position.
