Handle for Infant Carrier

Abstract

An infant swing has a base member supported by hanger members for reciprocal movement. The base member is formed with an upwardly extending mounting protrusion that nests into a mating receiver structure formed on the bottom of the seat carrier. A latch mechanism carried by the seat carrier is selectively operable to disengage a pivoted, spring-loaded latch member mounted on the base member mounting protrusion. The seat carrier is formed with a pivoted lift handle that provides a dual lift function, including the normal lift function associated with the lift handle being raised into the upright operative position. The lift handle is formed with grip openings adjacent the pivot connection of the lift handle such that the grip handles are rotated for access when the lift handle is lowered to the folded position to enable the seat carrier to be lifted by grasping the two transversely spaced grip openings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings, an infant swing incorporating the principles of the instant invention can best be seen. The infant swing 10, as can best be seen in FIGS. 1-3, includes as the major components thereof a support frame assembly 12, including a pair of transversely spaced rear legs 13 and a corresponding pair of front legs 14, and a seat assembly 15 suspended from the frame assembly 12 for a fore-and-aft swinging movement. As will be described in greater detail below, the seat assembly 15 is formed of a molded seat carrier 20 mounted on a base member 30 affixed to a pair of transversely spaced hangers 17 that are connected to corresponding hanger housings 18 positioned at the cantilevered ends of the rear legs 13.

Referring now to FIGS. 4-12, the seat carrier 20 can be configured for use in multiple applications, such as a car seat or a stroller, in addition to being used in the infant swing assembly 10 as will be described in detail below. The seat carrier 20 is preferably formed with an exterior shell 21 supporting a seat 22 onto which an infant is supported and restrained. The exterior shell 21 may have a removable tray 23 mounted at a forward position and defining a yoke 24 that prevents an infant from sliding forwardly out of the seat 22. The exterior shell 21 is also provided with a pivoted lift handle 25 that is movable between an upright position, shown in FIGS. 4 and 5, and a folded or retracted position which is shown in phantom in FIG. 5. One skilled in the art will recognize that the exterior shell of the seat carrier 20 is the preferred embodiment for the seat carrier 20, but that the seat carrier can be formed in other configurations to establish an infant carrier structure. Such alternative structures would include an exterior frame that would be capable of supporting the lift handle 25 and also support soft goods that define the infant seat. In general terms, an infant carrier is intended to identify any transportable infant carrying device.

As is best seen in FIGS. 8 and 9, the underside of the exterior shell 21 is formed with mounting structure 26 that is engagable with the base member 30. The mounting structure 26 includes a receptacle 27 that is formed to receive the mounting protrusion 32 of the base member 30 so that the seat carrier 20 is not horizontally movable relative to the base member 30. The receptacle 27 includes a latch opening 28 into which the latch member 33, biased by the spring members 33a to project outwardly from the receptacle 27 and pivotally mounted on the base member mounting protrusion 32, can pass to secure the seat carrier 20 on the base member 30 against vertical movement of the seat carrier 20. The mounting structure 26 is also preferably formed with an arcuate lower surface that allows the seat carrier 20 to be supported on a flat surface and be rocked. To negate this rocking motion, the mounting structure 26 can be provided with an extendable brace 29 that can selectively extend out of the back side of the mounting structure 26 to provide a stable, non-rocking support surface for the free-standing seat carrier 20.

The seat carrier 20 includes a latch actuation mechanism 35, best seen in FIGS. 10-12, operable to cause a pivotal movement of the latch member 33 to release the seat carrier 20 for vertical movement relative to the base member 30 and allow the seat carrier 20 to be lifted off the swing 10 and be removed therefrom. The latch actuation mechanism 35 includes an external pull member 36 that is connected via a pair of transversely spaced links 37 to a spring-loaded actuator 38 pivotally mounted to the exterior shell 21. When the latch member 33 snaps into the latch opening 28, the latch member 33 presses against the actuator 38. Pulling on the external pull member 36 causes a pivotal movement of the actuator 38 against the bias exerted thereon by the spring members 39 to push the latch member 33 out of the latch opening 28 and allow the seat carrier 20 to be lifted off of the base member 30.

Preferably, the infant swing 10 incorporates a recline mechanism 40, best seen in FIGS. 13-17. One of ordinary skill in the art will note that the recline mechanism 40 is housed within the base member 30, which is formed with a lower, fixed base shell 34 that is secured to the hanger members 17 and movable therewith. A top plate 31, which includes the mounting protrusion 32, is movably mounted on the fixed base shell 34 and slidable along an arcuate track 34a. As can be seen best in FIG. 16, the top plate 31 is supported on rollers 41 that project upwardly through the upper face 63 of the base shell 34 to facilitate the sliding movement of the top plate 31 relative to the base shell 34. The base shell 34 is formed with longitudinally extending slots 42 through which the mounting tab 44 of slide retainers 43 extend so that the top plate 31 can be secured to the slide retainers 43 which run under the upper face 63 of the fixed shell 34. With this structure, the top plate 31 is free to move along the arcuate track 34a without being separable from the fixed shell 34. The slide retainers 43 prevent the top plate 31 from separating from the fixed base shell 34 without hindering the sliding movement thereof, while the rollers 41 minimize any friction between the top plate 31 and the base shell 34.

The recline mechanism 40 further includes a push/pull actuator handle 45 that spans transversely across the base member 30 to project outboard thereof on both sides of the base member 30. The actuator handle 45 is carried by the top plate 31 and includes a center chamber 46 having a bottom opening therein to receive a center post 47 formed in the top plate 31. The center chamber 46 carries a pair of springs 48 positioned on opposing sides of the center post 47 to center the actuator handle 45 on the top plate 31 and bias the actuator handle 45 to a centered position. The actuator handle 45 also is formed with a pair of downwardly extending protrusions 49 that are engagable, respectively, with corresponding formed locking channels 50.

Each locking channel 50 is formed as a depression into the face 63 of the base shell 34 so that the protrusions 49 are received therein. Each locking channel 50 is formed with a series of longitudinally spaced blocks 52, as is best seen in FIGS. 14 and 16, with a longitudinal passageway 53 located on the transversely opposing sides of the blocks 52, which in turn are separated by transversely extending grooves 54 that interconnect the transversely spaced passageways 53. When the actuator handle 45 is in the centered position, the protrusions are located within the transverse grooves 54 between selected blocks 52. Pushing the actuator handle 45 to either side against the biasing force exerted by the corresponding centering spring 48 causes the protrusions 49 to move sideways into the corresponding longitudinal passageway 53. The top plate 31 is then free to move along the arcuate track 34a relative to the base shell 34 within the parameters defined by the longitudinal passageways 53.

When the caregiver has selected the desired reclined position, the actuator handle 45 is allowed to return to the centered position which will then position the protrusions 49 within the transverse grooves 54 between the blocks 52. The blocks 52 serve to prevent longitudinal movement of the protrusions 49 and, thus, movement of the top plate 31 relative to the base shell 34. Preferably, several blocks 52 are utilized in the locking channels 50 so that at least five recline positions are defined by the transverse grooves 54. One skilled in the art will recognize that other numbers of transverse grooves 54, and the corresponding recline positions, can be defined by a selected number of blocks 52 within the depressed locking channel 50.

With reference to FIGS. 18-22, the lift handle 60 can be formed in an embodiment that incorporates a dual lift function capability. The lift handle 60 can include a widened base portion 61 that includes the pivot connection 62 with the seat carrier 20 at each respective end of the lift handle 60 and a grip opening 65 formed forwardly of the corresponding pivot connection 62. When the lift handle 60 is positioned in the raised overhead configuration, as is depicted in FIGS. 18 and 20 and in phantom in FIG. 22, the grip openings 65 are located below the top edge 63 of the seat carrier 20, thus limiting the effectiveness of the grip openings 65 to provide a two-hand lift function. One skilled in the art will recognize that the grip openings 65, shown in cross-section in FIG. 28, can be formed with a wall 66 that converts the grip opening 65 into a grip member 68, as is depicted in FIG. 29. While the wall 66 prevents the caregiver's fingers from passing through the grip member 68, as they would for a grip opening 65, the formed grip member 68 provides adequate engagement structure, particularly when positioned above the top edge 63, as is described below. The further reference to grip openings 65 below is intended to include reference to the grip members 68.

However, when the lift handle 60 is lowered to the folded position, as can be seen in FIGS. 19, 21 and 22, the pivotal movement of the lift handle 60 re-orients the grip openings 65 from forwardly of the pivot axis 62 to a position vertically above the pivot axis 62. In this location, the caregiver can insert fingers through the grip openings 65, or grasp the grip members 68, and, using two hands, lift the seat carrier from one location to another. Since the grip opening 65 is located vertically above the pivot 62 of the handle 60, the seat carrier 20 can be lifted by the grip openings 65 without pivoting the handle 60. Thus, the lift handle 60 provides a lift function even when lowered into the normally inoperative folded position.

In FIGS. 23-27, an alternative embodiment of the grip openings 65 is depicted. While in the first embodiment shown in FIG. 22 is operable only when the handle 60 is lowered to the folded position, the grip openings 65 in this alternative embodiment are formed in a semi-circular configuration to wrap approximately 180 degrees around the pivot 62. With such a configuration of the grip openings 65, a first portion of the grip openings 65 will be located below the top edge 63, while a second portion is located above the top edge when the handle is in the upright position. Thus, the grip openings 65 are operable to provide a two-hand lift function even when the handle 60 is upright. When the handle 60 is pivoted to the lowered position, the first portion of the grip openings 65 are rotated above the top edge 63 to provide the two-hand lift function when the handle 60 is lowered, as well as when the handle 60 is raised.

In operation, the seat carrier 20 can be transferred from one application, such as a car seat, with the infant asleep therein and placed onto the base member 30 without waking the infant due to moving the infant from one seat to another. The seat carrier 20 automatically snaps into place by the spring-loaded latch member 33 deflecting due to engagement with the mounting structure 26 and locking into the latch opening 28 in the receptacle 27. By depressing the recline actuation handle 45 from either side of the seat carrier 20, the seat carrier 20 can be reclined to a desired orientation, whereupon the recline actuation handle 45 is released to allow the centering springs 48 to move the protrusions 49 into an interfering position with respect to the blocks 52 in the locking channels 50, the protrusions 49 passing into transverse grooves 54 between corresponding blocks 52.

The dual lift function lift handle 60 can provide a one-hand lift function when the lift handle 60 is raised into the upright, overhead position, and a two-hand lift function when the lift handle is lowered into the folded position by virtue of the pivotal movement of the lift handle re-orienting the grip openings 65 into an accessible position above the top edge of the seat carrier 20. Accordingly, the dual lift function lift handle 60 does not have to be raised in order to allow the seat carrier to be moved from one location to another.

It will be understood that changes in the details, materials, steps and arrangements of parts which have been described and illustrated to explain the nature of the invention will occur to and may be made by those skilled in the art upon a reading of this disclosure within the principles and scope of the invention. The foregoing description illustrates the preferred embodiment of the invention; however, concepts, as based upon the description, may be employed in other embodiments without departing from the scope of the invention.
