This invention relates to a swing. More specifically, this invention relates to a child swing with a fold mechanism.
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 are foldable. Folding the legs of such commercially available swings is not easy or intuitive. The fold mechanisms of these swings can be difficult to operate and/or difficult to locate.
In addition, 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.
An aspect of the present invention relates to a child swing that comprises a frame including first and second rear legs and first and second housings. First and second fold mechanisms pivotally connect the first and second rear legs to the first and second housings, respectively. The fold mechanisms each include a socket member to receive an upper end of the respective leg. The socket member is pivotally mounted to the respective housing to guide pivoting movement of the respective leg relative to the respective housing. The fold mechanisms each can further include a release lever pivotally mounted to the socket member, and a locking pin connected to the release lever for engagement with the respective housing to facilitation positioning of the respective leg in an in-use position and in a folded position.
Another aspect of the present invention relates to a child swing that comprises a frame including first and second front legs and first and second housings. First and second fold mechanisms pivotally connect the first and second front legs to the first and second housings, respectively. The fold mechanisms each include a socket member to receive an upper end of the respective leg. The socket member is pivotally mounted to the respective housing to guide pivoting movement of the respective leg relative to the respective housing.
A further aspect of the present invention relates to fold mechanism for a child swing, where the child swing includes a frame leg and a housing to which the frame leg is pivotally mounted by the fold mechanism. The fold mechanism comprises a socket member pivotally mounted to the housing and to which the frame leg is mounted. The socket member is configured to guide pivoting movement of the frame leg relative to the housing. The fold mechanism can further comprise a release lever pivotally mounted to the socket member, and a locking pin connected to the release lever for engagement with the housing to facilitate positioning of the frame leg in an in-use position and in a folded position.
Yet another aspect of the present invention relates to a child swing that includes a seat recline feature with more than one in-use position. The child swing 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.
Still 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.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several embodiments of the invention and, together with the description, serve to explain the principles of the invention.
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.
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.
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
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. The operation and structure of the swing handle assembly will be described below in connection with
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
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
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.
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
As can be seen from
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
When the leg 14 is in the in-use position, as shown in
To rotate the leg 14 from its in-use position to its folded position, the lever 74 is squeezed, and the pin 76 moves into the travel area 86 in the housing slot 80. When the pin 76 is in the travel area 86, the lever 74 and the socket 72 can pivot relative to the housing 50. The pin 76 rides along the track-like, travel area 86 as the rear leg 14 is pivoted to the fold position.
In one alternative embodiment, the lever 74 and the slot 80 in the housing 50 may be configured to require that the lever 74 be unlocked to move the leg 14 from the folded position to the in-use position. In another alternative embodiment, the rear leg fold mechanism 70 may be configured so that, rather than including a soft lock or a positive lock in the folded position, the mechanism 70 does not lock at all in the closed position.
The position and the method of activating the lever 74 facilitate folding of the leg 14. The lever 74 is located at an upper end of the leg 14, along a front surface of the leg 14, so that a user standing behind the swing can easily grip the lever 74 and fold the leg 14. The same squeezing motion used to grab the legs 14 of the swing will compress the lever 74 and move the pin 76 out of the lock area 82. The lever 74 rotates with the socket 72, so the likelihood that a user's fingers will get pinched between the parts of the fold mechanism 70 is minimal. The lever 74 is readily visible, as can be seen in
In addition, because the fold mechanism 70 occupies a relatively small area within the housing 50, the housing 50 itself can be relatively small in size. In this regard, the main body portion 72M of the socket 72, which is generally circular in shape, is positioned in a lower, rear location of the housing 50, and the upper end of the leg 14 extends into this socket 72. As compared to conventional swings, in which the upper end of the leg is connected directly to the housing and, hence, in which the housing must accommodate the pivoting of the leg from the in-use position to the fold position, the housing 50 of swing 1 can be much more compact.
Further, the fold mechanism 70 can be designed so that the socket 72 can be rotated to a sufficient degree to enable the rear legs 14 to contact the front legs 12 in a very compact fold. Additionally, although the leg 14 and the socket member 72 are formed as two separate components in the illustrated embodiment, it is conceivable that the leg 14 and the socket member 72 could be formed as a unitary construction. For example, the leg 14 and the socket member 72 could be made of a plastic material as a single die-cast component.
In another alternative embodiment, the lever 74 can be replaced with a side button release mounted to the side of the socket member. The side button release can be configured with two sets of teeth, one set to selectively engage mating teeth in the socket member and the other set to selectively engage teeth in the housing. Engagement of the teeth in this alternative embodiment controls pivoting of the socket member, and hence the leg of the swing frame, relative to the housing.
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.
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.
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).
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
Referring to
Rotation of the swing handle 60 relative to the handle support structure 110 to the entertain position is now described with reference to
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.
The support stop 122 may be generally L-shaped, as described above with respect to
Rotation of the swing handle 60 relative to the handle support structure 110 to the lift position is now described with respect to
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.
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
According to one embodiment of the invention illustrated in
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.
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.
