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
.
