This invention relates to a child swing. More specifically, this invention relates to a child swing that has a recline mechanism so that a child caregiver can recline the seat back of the swing with one hand.
Various types of swings are known. Typically, the swing includes a support frame, a hanger arm or arms pivotally attached to the support frame, and a seat attached to the hanger arm or arms. The swing also can include an electrically powered drive mechanism to move the swing seat in a back-and-forth motion.
Some swings include a seat back recline mechanism. The seat back of these swings can be adjusted to different recline angles relative to the seat bottom so that a caregiver can position the seat in various recline positions, including an upright position, a fully reclined position, or an intermediate position between the upright position and the fully reclined position, depending on the age and needs of the child. Older children may prefer a more upright position, while younger children with less neck control may prefer a more reclined position.
The seat back recline mechanism of one existing swing product includes a bent wire that travels along a slot or pair of slots formed as part of the seat back. The location of the wire in the slot determines the recline position of the swing seat. The wire can be mounted to hanger arms on either side of the seat back or to another suitable structure. To adjust the wire to a different recline location in the slot, a caregiver can use one hand to move the wire and the other hand to support the seat back. These wire arrangements are not intuitive or easy to operate for all caregivers.
A different seat back recline mechanism for a swing seat includes latches positioned on opposite sides of the seat back to engage latch-receiving ribs positioned on the hanger arms of the swing. The ribs correspond to different seat back recline angles. To change the recline angle of the seat back, a caregiver can grip the latches directly and re-position the latches against ribs corresponding to the desired seat back recline angle. This seat back recline mechanism can be awkward to operate for some caregivers.
There is a need for a swing with an improved seat back recline mechanism.
An aspect of the invention relates to a swing that includes a swing frame and a seat supported by the swing frame. The seat includes a seat bottom frame, a seat back frame movably coupled to the seat bottom frame, and a recline mechanism to recline the seat back frame relative to the seat bottom frame. The recline mechanism includes first and second mounts on opposite sides of the seat to movably mount the seat back frame to the seat bottom frame, at least one recline lock associated with at least one of the first and second mounts and configured to lock the seat back frame in at least two recline positions relative to the seat bottom frame, and a recline actuator having a grip intermediate the first and second mounts and movable between an un-actuated position and an actuated position. The at least one recline lock is movable between a locked position to set the recline position of the seat back frame relative to the seat bottom frame and an unlocked position to allow adjustment of the recline position of the seat back frame relative to the seat bottom frame. The recline actuator is coupled to the at least one recline lock such that movement of the recline actuator from the un-actuated position to the actuated position moves the at least one recline lock from the locked position to the unlocked position.
Another aspect of the invention relates to a swing seat configured to be suspended from a swing frame. The swing seat includes a seat bottom frame, a seat back frame movably coupled to the seat bottom frame, and a recline mechanism to recline the seat back frame relative to the seat bottom frame.

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 of
The frame 10 can include first and second front legs 11, first and second rear legs 12, housings 13 to which the front and rear legs 11, 12 are coupled, a front cross member 14 extending between the front legs 11, and a rear cross member 15 extending between the rear legs 12. In other embodiments, the frame can include first and second front legs only or first and second rear legs only. It will be understood that the seat 30 and associated one-hand recline mechanism 100 can be employed on swings with any frame configuration. Additionally, the frame 10 optionally can be configured to fold. For example the front and/or rear legs 11, 12 can be assembled so as to pivot within the respective housings 13, such as disclosed in U.S. Pat. No. 6,645,080, issued Nov. 11, 2003, and U.S. Publication No. 2004/0198512 A1, published Oct. 7, 2004, both of which are incorporated herein by reference in their entirety.
In electric swings, the swing, such as swing 1 of
The swing 1 also includes a one-hand recline mechanism 100 that enables the seat back 32 of the seat 30 to recline relative to the seat bottom 34. The seat back 32 and the seat bottom 34 of the seat include a seat back frame and a seat bottom frame covered by a fabric cover 36. In one embodiment, shown in
The one-hand recline mechanism 100, as can be seen in
The one-hand recline mechanism 100 also can include a recline lock 120 associated each mount 110; the recline locks 120 are hidden by the mounts 110 in
The one-hand recline mechanism 100 further includes a recline actuator 130 having a grip intermediate the first and second mounts 110. The recline actuator 130 is coupled to the recline locks 120, as will be described in connection with
As can be seen in
In the embodiment of
The plungers 124 are moved from their locked positions to their unlocked positions by the recline actuator 130. The recline actuator 130 can include an actuator mount 132 provided on the seat back frame 42, a grip 134 movably mounted to the actuator mount 132, and an arm 136 extending between the grip 134 and the plungers 124 of each recline lock 120. The grip 134 can include surface contouring, such as indentations, to approximate the shape of a user's fingers to facilitate gripping of the grip 134. The arm 136 can be in the form of a cable or a wire. The arm 136 can extend from the grip 134 along the contour of the tubular seat back frame 42 to each recline mount 110 for attachment to the respective plungers 124 of the recline locks 120. The arm 136 can include a bend 137 proximate each of its ends 138 so that the ends 138 can extend through aligned holes in the seat back frame 42 and respective plunger 124 to be secured to the plungers 124, as seen in
The actuator arm 136 is shown as a single continuous, generally U-shaped arm extending between the two reline mounts 110 and through the grip 134. Alternatively, the actuator arm can comprise first and second arms, the first arm extending from the grip 134 to the first recline mount 110 and the second arm extending from the grip 134 to the second recline mount. In addition, the actuator arm can take a different shape than the U-shape of the illustrated embodiment.
To move the plungers 124 from their locked positions to their unlocked positions, and hence unlock the recline locks 120, a caregiver can grasp the grip 134 and squeeze so that the grip 134 slides in a direction normal to the seat back frame 42, as indicated by arrow A in
In addition, the recline actuator 130 is arranged relative to the seat back frame 42 so that the seat back frame 42 can be supported by the same hand that actuates the recline actuator 130. For example, in the illustrated embodiment, the grip 134 of the recline actuator 130 is located at the top of the seat back frame 42, which enables the caregiver to support easily the weight of the seat back frame 42, and any child sitting in the seat, with the same hand that adjusts the recline position of the seat back frame 42. Locating the grip 134 at the top of the seat back frame 42 also makes the grip 134 visibly obvious and easy to access. It is contemplated that the grip 134 can be located along the perimeter of the seat back frame 42 and still allow a caregiver to both recline the seat back and support the weight of the seat back, and any child sitting in the seat, with one hand. In a case where the seat back frame is a hard-shelled plastic frame that approximates the shape of the seat back, the grip 134 can be located elsewhere on the frame, such as on a rear surface of frame.
A variation of the recline mechanism contemplated by the invention is to employ an arm having a grip along the arm itself, such as a bent location along the arm, to serve as the recline actuator. The arm of this variation extends between the mounts 110 and is positioned relative to the seat back frame 42 so that the caregiver can squeeze directly on the arm, at the grip, to release the recline locks 120. This variation eliminates the need for an actuator mount 132 or grip 134. Like grip 134, the arm grip is remote from the recline locks 120. The arm can be in the form of a wire or a cable.
The recline lock 120 is designed as a weight-bearing lock. That is, the recline lock 120 bears the weight of the seat back frame 42 and the child seated in the swing seat. The contact between the detents 122 and the plunger 124, as shown in
Another feature of the recline lock 120 is that the detents 122 can be configured so that the recline actuator 130 need only be actuated to recline the swing seat to a more reclined position and need not be actuated to re-position the swing seat in a less reclined, more upright position. As seen in
Another recline actuator 330 is shown in
The first rack 304 includes a plurality of recesses 310 that are sized to receive teeth 312 that extend around the pinion 308. Similar to the first rack 304, the second rack 306 also includes a plurality of recesses 314 sized to receive teeth 312 of the pinion 308. To actuate the recline actuator 330, the slide grip 334 can be pushed in a direction parallel to the seat back frame (not shown) as indicated by arrow D. When the slide grip 334 is pushed, the first rack 304 and its arm 336 also move in the direction of arrow D. When the first rack 304 moves in the direction of arrow D, the recesses 310, which are engaged with the teeth 312 of the pinion 308, cause the pinion 308 to rotate about its axis R. Rotation of the pinion 308 drives the teeth 312 into the recesses 314 of the second rack 306, causing the second rack 306 and its arm 336 to move in the direction of arrow E. As a result, both arms 336 are pulled toward the recline actuator 330, as shown in
To return the recline actuator 330 to the un-actuated position of
Other recline actuators are contemplated. For example, instead of the finger grip 134, the push-button grip 234, or the slide grip 334, a twisting or rotating grip could be used. The moving members 114 of the embodiments shown in FIGS. 3A and 3B of U.S. Pat. No. 6,068,284, issued May 30, 2000, which is incorporated herein by reference in its entirety, are two examples of twisting or rotating grips that could be used in a one-hand recline mechanism according to the present invention. The twisting or rotating grips also can include a lever mounted to the moving members that allows for translational (lever) and rotating (moving members) action instead of a pure rotation (moving members) action. Other embodiments may include squeezing action, rotating action, pinching action, pulling action, turning action, or any combination of those actions. A feature common to the various contemplated recline actuators is that they require only one hand to release the recline locks and to control the seat back as the seat back is reclined.
In addition, other recline locks are contemplated. For example, instead of recline locks 120, a gear arrangement with teeth that mesh and un-mesh could be used as the recline locks of the present invention. One suitable gear arrangement is described and illustrated in U.S. patent application Ser. No. 10/999,148, filed Nov. 30, 2004, which is incorporated herein by reference in its entirety. As another example, a VALCO button arrangement could be used as the recline locks of the present invention. The button could be disposed in each mount 110 to move in a direction parallel to the axis of rotation of the seat back. This button could be actuated by the recline actuator 130 in a manner similar to the manner in which the gear arrangement of U.S. patent application Ser. No. 10/999,148 is actuated.
As another alternative, where the seat bottom frame 44 is made of plastic, the mounts 110 and the seat bottom frame 44 can be molded as a single piece of material.
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.
