FOLDABLE SWING HAVING ROTATABLE HANDLE

FIELD OF THE INVENTION

[0001] This invention relates to a rotatable handle for a swing. More specifically, this invention relates to a rotatable handle for a foldable child swing.

BACKGROUND OF THE INVENTION

[0002] Various types of child or infant swings are known in the art. Typically, such swings include a support frame, hanger arms pivotably attached to the support frame, and a seat attached to the hanger arms.

[0003] It is also known to include a handle on the swing to allow a user to carry the swing. The handle is rigidly attached to the support frame, but the swing seat can sway back-and-forth as the swing is carried, which makes the swing somewhat awkward to move.

SUMMARY OF THE INVENTION

[0004] An aspect of the present invention relates to a swing that comprises a swing frame and a swing handle rotationally coupled to the swing frame such that the swing handle may rotate about a handle rotational axis between at least two positions. The swing further may comprise a swing seat and at least one hanger arm rotationally coupled to the swing frame and supporting the swing seat. The at least two positions may include a lift position wherein a central portioh of the swing handle is arranged above the rotational axis, an open access position wherein a centrai portion of the swing handle is arranged rearward of the .922254

CA 02450331 2003-11-20 rotational axis, an entertain position wherein a central portion of the swing handle is arranged forward of the rotational axis, and a storage position wherein a central portion of the swing handle is arranged forward and below the rotational axis.

[0005] According to the present invention, in the lift position, the swing handle may be locked to prevent rotation of the swing handle relative to the swing frame. In the open access position, the swing handle may be stopped from any further rearward rotation relative to the swing frame.'

In the entertain position, a detent mechanism may frictionally resist rotational motion by the swing handle in a forward or rearward direction relative to the swing frame. In the storage position, the swing handle may be nested between a seat back and a seat bottom of the swing when the swing is folded.

[0006] The swing also may comprise a handle support structure supported by the swing frame, and the swing handle may comprise a handle portion and a support interface portion. The support interface portion may be attached to the handle support structure. In addition, the handle portion may comprise at least one electronic device and electrical wiring extending from the at least one electronic device to the support interface portion. The electronic device may be a light producing device and/or a sound producing device. The support interface portion and the handle support structure may include at least one moving contact assembly to provide electrical contact between the handle support structure and the support interface portion, and the electrical wiring may electrically contact the at least one moving contact assembly. The moving contact assembly may be configured to maintain electrical contact ;

over a rotational angle range as the swing handle rotates relative to the handle support structure, and this rotational angle range may correspond to the angular range about the entertain position of the swing handle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] 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.

[0033] Figure 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.

CA 02450331 2003-11-20

[0034] 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 P1, and the seat bottom 24 is pivotally connected to the hanger arms 30 at pivots P2.

[0035] 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 Figures 7-9.

[0036] 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 Figures 12-21.

[0037] 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.

[0038] As mentioned above, the swing seat 20 can be moved between a fold position, a first, upright in-use position, and a second, reclined inuse 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.

[0039] The seat recline mechanism will now be described in connection with Figures 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. Figure 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.

[0040] 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 Figure 2, the latch 200 is spaced from the pivot P1.

[0041] The latch 200 has a U-shaped segment 250 configured for insertion into the channel 210 between ribs 220, 230, a flange 260 at .922254

CA 02450331 2003-11-20 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. Figure 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.

[0042] 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 Figure 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.

[0043] Figure 4 shows the inner surface of the'Ieft-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 C1, to receive the pivot P1 of the seat back 22 and the pivot P2 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 Figure 5. To position the seat back 22 in the second, reclined in-use position, the locking ridge 270 of each iatch 200 is positioned

922254

CA 02450331 2003-11-20 against the second rib 302 of the respective hanger arm 30, as shown in Figure 6.

[0044] As can be seen from Figure 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 inuse 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.

[0045] 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 rearwardiy, toward the seat back 22.

922254

CA 02450331 2003-11-20

[0046] 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.

[0047] 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 Figure 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.

[0048] The swing fold operation will now be described in connection with Figures 7-9. Figure 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.

[0049] Figures 10, 10A, 11A, and 11B 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

922254

CA 02450331 2003-11-20

74, and a locking pin 76 connected to the release lever 74. As shown in Figure 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 P3 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 Figure 11 A, 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. Figure 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 Figure 11 B, 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.

922254

CA 02450331 2003-11-20

[0050] 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 Figure 8. The swing handle 60 can be moved to the storage position either before or after folding of the rear legs 14.

[0051] 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. Figure 9 illustrates the swing 1 in its fully folded position.

[0052] 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 Figure 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.

[0053] Figure 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 Figure 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 Figurel), 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

922254

CA 02450331 2003-11-20 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 1 62, as shown in Figure 1.

[0054] 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 Figurel).

[0055] Figure 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.

[0056] 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 Figure 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.

[0057] Referring to Figure 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 .922254

CA 02450331 2003-11-20 edge facing the support stop 122 when in contact with the support stop 1 22. The support stop 1 22 may he 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 Lshaped 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.

[0058] Rotation of the swing handle 60 relative to the handle support structure 110 to the entertain position is now described with reference to Figures 1,12, and 15. Figure 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 Figure 1} to provide lights and/or sounds for entertainment.

922254

CA 02450331 2003-11-20

[0059] 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.

[0060] Figure 1 5 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.

[0061] The support stop 122 may be generally L-shaped, as described above with respect to Figures 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 Figure 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

S22254

CA 02450331 2003-11-20

Atty. Dkt. No.: 061270-0813 entertain position, but not so much resistance as to make it difficult to rotate the handle out of the entertain position. Figure 1 illustrates the swing with the handle 60 in the entertain position.

[0062] Rotation of the swing handle 60 relative to the handle support structure 110 to the lift position is now described with respect to Figures 12, 16, and 17. Figure 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.

[0063] 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.

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 1 60 lines up with recess 1 62, 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. Figure 17 illustrates the swing with the handle 60 in the lift position.

[0065] 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.

[0066] Rotation of the swing handle 60 relative to the handle support structure 110 to the storage position is now described with respect to Figures 12, 20, and 21. Figure 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.

[0067] According to one embodiment of the invention illustrated in Figure 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 1 64 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.

[0068] Figures 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 Figure 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.

[0069] 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 1 62 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.

[0070] The support interface portion 114 may include an outer peripheral wall 170 adjacent the handle portion 112. In order to pass the wiring 1 61 from the cavity 1 64 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 11 2 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.

[0071] 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.

[0072] 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.

[0073] 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

922254

CA 02450331 2003-11-20 screws or glue. The wiring 160 electrically contacts the generally arc shaped contact 172 via spring contacts 174.

[0074] 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.

[0075] 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 Figure 1).

[0076] 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 electricaldevices 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 1 72 is possible, and the limited size of the generally arc shaped contact 1 72 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

922254

CA 02450331 2003-11-20 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.

[0077] 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.

[0078] The preferred embodiments have been set forth herein for the purpose of illustration. This description, however, should not be deemed to be a limitation on the scope of the invention. Various modifications, adaptations, and alternatives may occur to one skilled in the art without departing from the claimed inventive concept. The true scope and spirit of the invention are indicated by the following claims.
