Description




FIELD OF THE INVENTION




This invention relates to a swing. More specifically, this invention relates to a child swing with a seat recline mechanism.




BACKGROUND OF THE INVENTION




Various types of swings are known in the art. Typically, swings include a support frame, hanger arms pivotably attached to the support frame, and a seat attached to the hanger arms. Electrically powered drive mechanisms are utilized to supply energy to the swing to move the swing seat in a reciprocal motion back and forth.




Some commercially available swings include a seat recline feature. The seat back of these swings can be adjusted to different angles relative to the seat bottom so that a parent can position the seat in either an upright position or a reclined position, depending on the need of the child. Older children may prefer the upright position, while younger children with less neck control may prefer the reclined position.




The seat recline mechanism for such swings typically includes a bent wire that travels along a slot in the seat back. The wire arrangement engages the hanger arms on either side of the seat to position the seat back at the appropriate recline angle relative to the seat bottom. Such a wire arrangement, however, is relatively expensive to manufacture and is not readily visible to a parent from the front of the swing.




Foldable swings also are known in the art. The swing seat of such a foldable swing can be adjusted between an open, in-use position and a closed, folded position. When in use, the seat back of the swing seat cannot be adjusted to different recline angles and, accordingly, children who wish to be fully reclined may be uncomfortable in the swing.




Thus, there is a need for an improved foldable swing that provides more than one in-use position.




SUMMARY OF THE INVENTION




An aspect of the present invention relates to a foldable swing that includes a seat recline feature.




Another aspect of the present invention relates to a child swing that comprises a frame, a seat including a seat back, and at least one hanger arm that connects the seat to the frame. The seat back of the swing seat is positionable in a first in-use position, in a second in-use position in which the seat back is adjusted rearward relative to its first in-use position, and in a fold position in which the seat back is adjusted forward relative to its first in-use position. The frame may be movable between an in-use position and a fold position. In this regard, the seat back may be positionable in its first and second in-use positions while the frame is in its in-use position, and the seat back may be positionable in its fold position while the frame is in its fold position.




The swing may further comprise a seat recline mechanism that engages the seat back with the at least one hanger arm. The seat recline mechanism may comprise at least one latch positioned on a side of the seat back for engagement with the at least one hanger arm. The seat back is pivotally connected to the at least one hanger arm by a pivot, and the at least one latch may be located on the side of the seat back at a location spaced from the pivot.




In another aspect of the invention, the at least one hanger arm may comprise a pair of hanger arms, and the at least one latch may comprise a pair of latches, one positioned on each side of the seat back for engagement with a respective one of the hanger arms.




The hanger arms each may include a first rib and a second rib. The first rib may be engageable by the respective latch when the seat back is in the first in-use position, and the second rib may be engageable by the respective latch when the seat back is in the second in-use position.




The frame may include first and second front legs, first and second rear legs, and first and second housings, where the first and second rear legs are pivotally connected to the first and second housings. The frame may further include a handle pivotally connected to the first and second housings.




Yet another aspect of the invention relates to a seat recline mechanism for a child swing, in which the mechanism comprises at least one latch positioned on a side of a seat back of the swing, and first and second latch-receiving members positioned on a hanger arm of the swing. The at least one latch is configured to engage the first latch-receiving member to position the seat back in a first in-use position, is configured to engage the second latch-receiving member to position the seat back in a second in-use position in which the seat back is adjusted rearward relative to the first in-use position, and is configured to be disengaged from the hanger arm to position the seat back in a fold position in which the seat back is adjusted forward relative to the first in-use position. The at least one latch may comprise a pair of latches, one positioned on each side of the seat back for engagement with a respective hanger arm of the swing. The first and second latch-receiving members may comprise first and second ribs positioned on the hanger arm.




It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Reference will now be made in detail to presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. An effort has been made to use the same reference numbers throughout the drawings to refer to the same or like parts.





FIG. 1

illustrates a swing


1


according to an exemplary embodiment of the present invention. The swing


1


has a foldable frame and a reclinable swing seat


20


that can be moved between a fold position, a first, upright in-use position, and a second, reclined in-use position. The swing


1


also includes a handle


60


that can be used to carry the swing. The handle


60


can be rotated between at least two positions. For example, in one embodiment, the handle


60


can be rotated between four positions, including: an open access position during which a child can be seated in the swing, a lift and lock position during which the swing can be carried by the handle, an entertain position during which a child seated in the swing can view lights and/or other play features of the handle, and a storage position during which the handle can be compactly stored when the frame is folded. The number of positions may also be more than four.




The swing


1


generally includes a support frame


10


, a seat


20


having a seat back


22


and a seat bottom


24


, and pair of hanger arms


30


that connect the seat


20


to the support frame


10


. The seat back


22


is pivotally connected to the hanger arms


30


at pivots P


1


, and the seat bottom


24


is pivotally connected to the hanger arms


30


at pivots P


2


.




The support frame


10


generally includes front legs


12


, rear legs


14


, a front cross member


16


extending between the front legs


12


, a rear cross member


18


extending between the rear legs


14


, and first and second housings


50


. In the illustrated embodiment, the front legs


12


of the support frame


10


are fixedly connected to the respective housings


50


, and the rear legs


14


of the support frame


10


are pivotally connected to the respective housings


50


to allow the swing


1


to fold, as will be explained below. Alternatively, the front legs can be pivotally connected to the respective housings, and the rear legs can be fixedly connected to the respective housings. In a further embodiment, both the front and rear legs can be pivotally connected to the housings. The fold swing operation will be described below in connection with

FIGS. 7-9

.




The support frame


10


, in addition to supporting the support hangers


30


and ultimately the seat


20


, also supports a swing handle


60


, which is part of a swing handle assembly. The swing handle


60


is rotationally connected at either end to the housings


50


and to the hanger arms


30


. The operation and structure of the swing handle assembly will be described below in connection with

FIGS. 12-21

.




The swing


1


also can include a power supply


52


within one of the housings


50


for supplying power to a motor to drive the motion of the swing


1


and/or for supplying power to the swing's electronic devices. The power supply


52


may comprise, for example, a battery holder for holding batteries.




As mentioned above, the swing seat


20


can be moved between a fold position, a first, upright in-use position, and a second, reclined in-use position. More specifically, the seat back


22


of the swing seat


20


is positionable in a first, upright in-use position, in a second, reclined in-use position in which the seat back


22


is adjusted rearward relative to its first in-use position, and in a fold position in which the seat back


22


is adjusted forward relative to its first, upright in-use position. While the frame


10


of the swing


1


is in-use, that is, erect, the seat back


22


can be positioned in its first and second in-use positions, and, when the frame


10


is folded for storage, the seat back


22


can be positioned in its fold position.




The seat recline mechanism will now be described in connection with

FIGS. 2-6

. The seat recline mechanism includes a latch


200


positioned on each side of the seat back


22


for engagement with the respective hanger arms


30


.

FIG. 2

is a detail view of the right side of the seat back


22


and the latch


200


. Although the figures generally show the structural relationship between the seat


20


and the hanger arms


30


by reference to only one hanger arm


30


, it will be understood that, in the illustrated embodiment, the seat-hanger arm relationship on the left and right sides of the swing are mirror images.




The seat back


22


includes a channel


210


molded along at least a portion of the perimeter of the rear surface


23


of the seat back


22


. Upper and lower ribs


220


,


230


are positioned in the channel


210


for capturing the latch


200


therebetween. The seat back


22


also includes a slot


240


adjacent the ribs


220


,


230


for receipt of a portion of the latch


200


. As seen in

FIG. 2

, the latch


200


is spaced from the pivot P


1


.




The latch


200


has a U-shaped segment


250


configured for insertion into the channel


210


between ribs


220


,


230


, a flange


260


at one end of the U-shaped segment


250


, and a locking ridge


270


at the other end of the U-shaped segment


250


. The flange


260


is configured for insertion into slot


240


in a snap fit to secure the latch to the seat back


22


.

FIG. 3

illustrates the latch


200


positioned in the channel


210


of the seat back


22


, with flange


260


extending through slot


240


. The locking ridge


270


is configured to engage latch-receiving members, such as ribs, on the hanger arms


30


to secure the seat back


22


in a selected in-use position.




The latch


200


also includes a segment


280


with finger bumps


282


. A user can press on the finger bumps


282


to flex the latch


200


inwardly, about the U-shaped segment


250


, in the direction of arrow A in

FIG. 2

to disengage the latch from the hanger arms


30


. This segment


280


may be visible to the user to facilitate positioning of the seat back to a desired in-use position.





FIG. 4

shows the inner surface of the left-side hanger arm


30


in accordance with the invention, the right-side hanger arm


30


being a mirror image. The hanger arm


30


includes two through holes, one of which is labeled C


1


, to receive the pivot P


1


of the seat back


22


and the pivot P


2


of the seat bottom


24


, respectively. In other embodiments, the seat back


22


and the seat bottom


24


can share a common pivot, and the hanger arm can include a single hub or single through hole to receive the pivot. The hanger arm


30


also includes first and second ribs


300


,


302


corresponding to the first, upright in-use position and the second, reclined in-use position, respectively. To position the seat back


22


in the first, upright in-use position, the locking ridge


270


of each latch


200


is positioned against the first rib


300


of the respective hanger arm


30


, as shown in FIG.


5


. To position the seat back


22


in the second, reclined in-use position, the locking ridge


270


of each latch


200


is positioned against the second rib


302


of the respective hanger arm


30


, as shown in FIG.


6


.




As can be seen from

FIG. 2

, the locking ridge


270


has a flat surface


271


and an angled surface


272


. Due to the configuration of the locking ridge


270


, the user only needs to actuate the latch


200


to move the seat back


22


in a rearward direction, for example, from the upright in-use position to the reclined in-use position. The user need not actuate the latch


200


to move the seat back


22


in a forward direction, for example, from the reclined in-use position to the upright in-use position. When moving the seat back


22


forward from the reclined in-use position toward the upright in-use position, the user can grip the seat back


22


and pivot it forward, which causes the angled surface


272


to ride over the first rib


300


. The latch


200


flexes inward until it passes the rib


300


and then restores to its at-rest configuration. At this point, the user can release the seat back


22


to allow the flat surface


271


to rest on the first rib


300


. The seat back


22


can be moved from the upright in-use position to the fold position in the same manner, that is, by simply gripping the seat back


22


and pivoting it forward.




In addition to ribs


300


,


302


, each hanger arm


30


can include a rib


304


on its inner surface, forward of rib


302


, to maintain the seat back


22


in the fold position. The rib


304


has a detent so that, when folded, the side of the seat back


22


comes into contact with the detent in a friction fit and is maintained in the fold position until the user pushes the seat back


22


rearward, away from the rib


304


. Similarly, the hanger arms


30


each can include a rib


306


with a detent for engagement with a side of the seat bottom


24


to maintain the seat bottom


24


in a fold position when pivoted upwardly and rearwardly, toward the seat back


22


.




Although only two in-use positions are shown in the figures, it will be understood that the hanger arms


30


can include additional ribs representative of additional in-use positions. Further, although the figures show the seat


20


suspended from a pair of hanger arms


30


, the present invention envisions a swing having a single hanger arm to suspend the seat.




The latches


200


can be integrally molded as a unitary body with the seat back


22


, or they can be fabricated separately from the seat back


22


and later releasably attached to the seat back


22


as shown in FIG.


2


. When fabricated separately, the latches


200


can have a different color than the seat back


22


to make them more visible to the user. In addition, the latches


200


can be fabricated from any suitable material, including plastic (such as acetal), steel, and aluminum. When the latch


200


is fabricated from a relatively rigid material, such as a metal or metal alloy, as opposed to a flexible plastic, the latching force achieved by deformation and restoration of the plastic latch material can be accomplished by a spring appropriately located relative to the metal latch


200


and the channel


210


.




The swing fold operation will now be described in connection with

FIGS. 7-9

.

FIG. 7

shows the swing in an in-use position, the seat back


22


in its first, reclined in-use position, and the swing handle


60


in its lift and lock position. A rear leg fold mechanism


70


is mounted to each rear leg


14


adjacent each housing


50


. To fold the swing


1


, the rear leg fold mechanisms


70


are actuated by the user so that the rear legs


14


can pivot relative to the housings


50


toward the front legs


12


.





FIGS. 10

,


10


A,


11


A, and


11


B illustrate the rear leg fold mechanism in more detail. The rear leg fold mechanism generally includes a leg socket member


72


to which the rear leg is mounted, a release lever


74


, and a locking pin


76


connected to the release lever


74


. As shown in

FIG. 10A

, the locking pin


76


of the illustrated embodiment is formed as part of the release lever


74


; however, it will be understood that the locking pin


76


can be molded separately from, and then connected by a suitable fastener to, the release lever


74


. The socket member


72


is rotationally mounted to the respective housing


50


about pivot P


3


and rotates with the rear leg


14


between the in-use position and the fold position. The locking pin


76


of the release lever


74


is configured to be captured in slots


78


,


80


in the socket member


72


and the housing


50


, respectively. The slot


78


in the socket member


72


has a slight arc to allow the pin


76


to move radially outward (when the lever


74


is squeezed) and radially inward (when the lever


74


is released). The slot


78


in the housing


50


is generally C-shaped to include a lock area


82


, a folded detent area


84


, and a travel area


86


between the two. When the lever


74


is released, as shown in

FIG. 11A

, the pin


74


can remain located in the lower, lock area


82


and the leg


14


cannot rotate. When the lever


74


is squeezed, the pin


76


rotates into the travel area


86


in the housing slot


80


, and the pin


76


rides along this track-like area as the rear leg


14


is pivoted to the fold position.

FIG. 8

shows the rear legs


14


in a partially pivoted position. In this position, the locking pin


76


is located in travel area


86


. When the rear leg


14


is completely folded, as shown in

FIG. 11B

, the pin


76


is free to move to the folded detent area


84


to lock the leg


14


in place. This area


84


has a lead out angled surface


88


that creates a detent or soft lock. Because there is no positive lock in this area


84


, the legs


14


can be moved to the in-use position without squeezing the lever


74


. The degree of the angled surface


88


will determine the amount of force needed to move the legs


14


to the in-use position. Although the figures show fold mechanisms associated with the rear legs, it is envisioned that, in an alternative swing arrangement, the fold mechanisms could be associated with the front legs.




In addition to the pivoting of the rear legs


14


, the swing handle


60


is pivoted during the fold operation. The swing handle


60


is pivoted from an in-use position (one of the open access position, the lift and lock position, and the entertain position) to the storage position, in the direction of arrow B in FIG.


8


. The swing handle


60


can be moved to the storage position either before or after folding of the rear legs


14


.




Once the swing handle


60


is in the storage position, the seat back


22


and the seat bottom


24


are pivoted to their fold positions. That is, the seat back


22


and the seat bottom


24


are pivoted toward each other until the back and bottom


22


,


24


frictionally engage the detents of the respective ribs


304


,


306


on the inner surface of the hanger arms


30


. The swing handle


60


nests between the seat back


22


and bottom


24


when all three structures are folded.

FIG. 9

illustrates the swing


1


in its fully folded position.




If the user wants to carry the folded swing


1


, the user can maintain the swing handle


60


in the lift and lock position shown in FIG.


7


and fold the remaining swing structures, including the rear legs


14


, the seat back


22


, and the seat bottom


24


. In this regard, the swing handle assembly operates independently of the remaining fold structures.





FIG. 12

illustrates a swing handle assembly


100


according to an exemplary embodiment of the invention. Such a swing handle assembly


100


is present at each end of the swing handle


60


to mount the swing handle


60


to the frame


10


(shown in FIG.


1


). The swing handle assembly


100


includes an end of the swing handle


60


and a handle support structure


110


. The handle support structure


110


is positioned within a respective housing


50


(shown in FIG.


1


), and it may be integrally molded with the housing


50


or may be attachable to the housing


50


. The swing handle


60


is rotationally coupled to the handle support structure


110


such that the swing handle


60


may rotate about a handle rotational axis RA between at least two positions. In addition, the swing handle


60


may include a number of electronic devices


162


, as shown in FIG.


1


.




The swing handle


60


may comprise a handle portion


112


and a support interface portion


114


. The support interface portion


114


is the portion of the swing handle


60


that is attached to the handle support structure


110


. The support interface portion


114


is positioned within the respective housing


50


(shown in FIG.


1


).





FIG. 13

illustrates the swing handle


60


rotated relative to the handle support structure


110


so that the swing handle


60


is in an open access position. In this position, a central portion of the swing handle


60


, which includes the central portion of the handle portion


112


, is arranged rearward of the rotational axis of the handle


60


. In this application forward of the rotational axis is toward a front of the swing


1


and rearward of the rotational axis is toward the rear of the swing


1


.




In this open access position, access to the seat


20


is easily facilitated because the swing handle


60


is out of the way relative to the seat


20


, as illustrated in

FIG. 14. A

child may be easily placed within the seat


20


while the swing handle


60


is rotated rearward. In this open access position, the swing handle


60


is stopped from any further rearward rotation relative to the handle support structure


110


and the frame


10


. The swing handle


60


is stopped relative to the support structure


110


when a handle stop


120


on the handle


60


meets a support stop


122


on the handle support structure


110


.




Referring to

FIG. 13

, the handle stop


120


is located on an outer peripheral wall


124


of the support interface portion


114


. The handle stop


120


may be shaped, for example, as a protrusion with a flat edge facing the support stop


122


when in contact with the support stop


122


. The support stop


122


may be shaped, for example, as a protrusion with a flat edge facing the handle stop


120


when in contact with the handle stop


120


. In particular, the support stop


122


may be generally L-shaped with a radial rib


121


of the L facing the handle stop


120


. The radial rib


120


extends radially from the axis of rotation. The radial rib


121


contacts the handle stop


120


when the handle stop


120


meets the support stop


122


. The support stop


122


may also include a circumferential rib


123


extending in a circumferential direction relative to the axis of rotation. In this respect, the support stop


122


has a dual function: to facilitate positioning of the swing handle


60


in the open access position, as explained above, and to facilitate positioning of the swing handle


60


in the entertain position, as will be explained below.




Rotation of the swing handle


60


relative to the handle support structure


110


to the entertain position is now described with reference to

FIGS. 1

,


12


, and


15


.

FIG. 15

illustrates the swing handle


60


rotated relative to the handle support structure


110


so that the swing handle


60


is in an entertain position. In this position, a central portion of the swing handle


60


is arranged forward of the rotational axis of the swing handle


60


, when the swing handle


60


is arranged as part of the swing. The swing handle


60


and handle support structure


110


are configured so that, when the swing handle


60


is in this entertain position, the central portion of the swing handle


60


is positioned above and/or in front of a child seated in the swing. Thus, the child would be able to easily view the swing handle


60


and any toys and/or electronic stimuli associated with the handle


60


. In this regard, the swing handle


60


may include features to entertain the child. As described further below, the swing handle may include electronic devices


162


(shown in

FIG. 1

) to provide lights and/or sounds for entertainment.




To maintain the swing handle


60


in the entertain position, the support interface portion


114


includes a detent mechanism that frictionally resists rotational motion by the swing handle


60


in a forward or rearward direction relative to the handle support structure


110


and the swing frame


10


. The detent mechanism may comprise, for example, one or more detents on one of the support interface portion


114


of the swing handle


60


and the handle support structure


110


. The other of the support interface portion


114


and the handle support structure


110


includes a protrusion, as part of the detent mechanism, arranged such that when the swing handle


60


is rotated in a first direction relative to the handle support structure


110


and the detent and the protrusion meet, the detent frictionally resists rotational motion by the swing handle


60


in the first direction or in a direction opposite to the first direction.





FIG. 15

illustrates an example where the detent


150


is on the support interface portion


114


of the swing handle


60


. In this case, the support stop


122


may serve as the protrusion that frictionally resists the detent


150


when the detent


150


and the support stop


122


meet. Alternatively, the protrusion may be other than the support stop


122


.




The support stop


122


may be generally L-shaped, as described above with respect to

FIGS. 12 and 13

. The radial rib


121


of the L extends radially from the center of rotation and acts to stop the handle stop


124


, as explained with respect to the open access position of FIG.


13


. The radial rib


121


may be angled such that its radially distance from the rotation axis increases along the rotation axis. The circumferential rib


123


of the L extends circumferentially and engages the detent


150


to provide frictional engagement between the support stop


122


and the detent


150


as the detent


150


moves along the support stop


122


. The circumferential rib


123


and the height of the detent


150


are set to provide sufficient resistance to rotation to hold the swing handle


60


in the entertain position, but not so much resistance as to make it difficult to rotate the handle out of the entertain position.

FIG. 1

illustrates the swing with the handle


60


in the entertain position.




Rotation of the swing handle


60


relative to the handle support structure


110


to the lift position is now described with respect to

FIGS. 12

,


16


, and


17


.

FIG. 17

illustrates the swing handle


60


rotated relative to the handle support structure


110


so that the swing handle


60


is in the lift position. In this position, a central portion of the swing handle


60


is arranged generally above the rotational axis of the swing handle


60


, when the swing handle is arranged as part of the swing. In this lift position, the swing handle


60


is locked relative to the handle support structure


110


and frame


10


. The swing


1


may be lifted by grasping the swing handle


60


and lifting. Because the rotational motion of the swing handle


60


is locked relative to the swing frame


10


, the swing


1


may be more easily carried without awkwardness otherwise caused by freely swinging motion of the swing frame


10


relative to the swing handle


60


.




The swing handle may be locked relative to the swing frame


10


and handle support structure


110


by means of a protrusion and matching recess. For example, one of the support interface portion


114


of the swing handle


60


and the handle support structure


110


may include a protrusion, and the other of the support interface portion


114


and the handle support structure


110


may include a recess matched to the protrusion such that, when the protrusion is within the recess, the swing handle


60


is locked relative to the handle support structure


110


. The locking mechanism of the protrusion and recess may also incorporate a user-activated lock.





FIGS. 12 and 16

illustrate an example where the protrusion


160


is on an inner peripheral wall


164


of the support interface portion


114


of the swing handle


60


, and the recess


162


is on an outer peripheral wall


166


of the handle support structure


110


. When the swing handle


60


is rotated such that the protrusion


160


lines up with recess


162


, the handle


60


may be grasped and lifted so that the protrusion


160


enters the recess


162


, and further rotational motion of the swing handle


60


relative to the handle support structure


110


, in either rotational direction, is prevented. The locking of the handle


60


relative to the handle support structure


110


may be released by lowering the handle


60


(such as by pushing on the handle


60


) relative to the handle support structure


110


to disengage the protrusion


160


from the recess


162


.

FIG. 17

illustrates the swing with the handle


60


in the lift position.




The lift and lock mechanism described above with the matching protrusion and recess provides a number of advantages. Locking action is transparent to the user with no secondary action required. Moreover, the design uses few moving parts and is easy to assemble. Further, cost effective materials can be used to achieve the desired function.




Rotation of the swing handle


60


relative to the handle support structure


110


to the storage position is now described with respect to

FIGS. 12

,


20


, and


21


.

FIG. 21

illustrates the swing handle


60


rotated relative to the handle support structure


110


so that the swing handle


60


is in a storage position. In the storage position, the rotational motion of the swing handle


60


relative to the handle support structure


110


need not be stopped, locked, or frictionally resisted by structures on the swing handle


60


and/or handle support structure


110


, because the relative rotation is prevented by nesting of the swing handle


60


between the seat back


22


and the seat bottom


24


of the seat


20


. The swing handle


60


may be nested between the seat back


22


and the seat bottom


24


of the seat


20


, when the swing is in a folded position.




According to one embodiment of the invention illustrated in

FIG. 12

, the handle


60


and handle support structure


110


include structure to allow the handle


60


to be snapped onto the handle support structure


110


, and thereafter the handle


60


is rotationally fixed to the handle support structure


110


. In this regard, the outer peripheral wall


166


of the handle support structure


110


includes a snap finger


180


. When the handle


60


is assembled to the handle support structure


110


such that the inner peripheral wall


164


of the support interface section


114


passes over and past the snap finger


180


, the snap finger


180


extends radially outward and beyond a lip


182


of the inner peripheral wall


164


. This extension of the snap finger


180


beyond the lip


182


prevents the handle


60


from being slid off of the handle support structure


110


.





FIGS. 18 and 19

illustrate another aspect of the invention wherein electrical wiring


161


extends from the handle portion


112


of the swing handle


60


into and through the support structure


110


so that electronic devices


162


(see

FIG. 1

) on the handle portion


112


may be powered by a power supply not in the handle portion


112


, but in one of the housings


50


.




The wiring


161


extends into a cavity


164


within the handle portion


112


to the electronic devices


162


on the handle portion


112


. The electronic devices may be, for example, light producing electronic devices and/or sound producing electronic devices. For example, if the electronic devices


162


are for the entertainment of a child in the swing, one or more of the electronic devices


162


may be a colored light shaped as a pleasing design for a child, such as a star or a cat. The electronic devices


162


may also produce sounds instead of, or in addition to, light. For example, if the electronic device is a colored light shaped as a cat, the device may also produce a “meow” sound. One or more of the electronic devices


162


may also produce sounds such as music, for example.




The support interface portion


114


may include an outer peripheral wall


170


adjacent the handle portion


112


. In order to pass the wiring


161


from the cavity


164


of the handle portion


112


to the support interface portion


114


of the handle


60


, the outer peripheral wall


170


may include a slot


171


. The slot


171


allows for an electrical connection between the handle portion


112


and the interface portion


114


. An electrical connection or contact between the support interface portion


114


and the handle support structure


110


may be implemented by means of at least one moving contact assembly.




Beneficially the moving contact assembly allows electronics to be powered in a movable handle, i.e., the handle


60


, through wiring passing through a rotating joint, i.e., the joint of the support interface portion


114


and the handle support structure


110


.




The moving contact assembly may comprise a generally arc shaped contact


172


on the handle support structure


110


and at least one spring contact


174


on the support interface portion


114


. The spring contacts


174


are adapted to electrically contact the generally arc shaped contact


172


as the swing handle


60


rotates relative to the handle support structure


110


.




The generally arc shaped contact


172


may comprise a printed circuit board or conductive ink formed on a surface of the handle support structure


110


, for example. If the generally arc shaped contact


172


comprises a printed circuit board, the handle support structure


110


may comprise a board mounting slot, so that the printed circuit board may be fixedly attached to the handle support structure


110


via the board mounting slot by snapping into the slot. Alternately the printed circuit board may be fixedly attached to the handle support structure


110


by screws or glue. The wiring


160


electrically contacts the generally arc shaped contact


172


via spring contacts


174


.




The spring contacts


174


may be formed of any appropriate material, and may be, for example, formed of a sheet metal stamping, conductive plastic, or graphite, for example.




The spring contacts


174


may pass through respective slots of the at least one slot


178


on the support interface portion


114


. The wiring


161


may we attached to the support interface portion


114


by wrapping the wiring


161


around respective support posts


301


. The spring contacts


174


may be attached to the wiring


161


using a contact snap


180


attached to the support interface portion


114


. Power supply wiring (not shown) may then extend from the generally arc shaped contact


172


to the power supply


52


(shown in FIG.


1


).




The moving contact assembly comprising the generally arc shaped contact


172


and the spring contacts


174


provides an electrical contact between the generally arc shaped contact


172


and the spring contacts


174


as the swing handle


60


is rotated relative to the handle support structure


110


. The arc length of the generally arc shaped contact


172


determines the rotational range over which electrical contact is maintained between the generally arc shaped contact


172


and the spring contacts


174


, and thus the range over which power is supplied to the electronic devices


162


. Because the electrical devices


162


may need to operate only over a limited rotational range of the handle


60


, limiting the arc length of the generally arc shaped contact


172


is possible, and the limited size of the generally arc shaped contact


172


may beneficially reduce its cost. The electrical devices


162


may need to operate only over a rotational range where the swing handle


60


rotates over a certain angle forward and rearward of the entertain position, for example. In one embodiment, the position and arc length of the generally arc shaped contact


172


is configured so that the electrical devices


162


work at the lift position and at ±60 degrees from the lift position, where +60 degrees includes the entertain position.




As an alternative, the swing handle


60


itself may contain a battery support structure for containing batteries and providing power to the electronic devices


162


on the swing handle


60


. In this case, the swing handle


60


need not include wiring to the power supply


52


within the housing


50


.
