TECHNICAL FIELDThe present invention relates generally to the field of children's accessories, and more particularly to motion devices for children.
BACKGROUNDVarious forms of children's motion devices are known for use with infants and children at different stages of their development. For example, bouncers, jumpers, rockers, seats, swings, and the like are used to provide entertainment, exercise and/or calming motion for children. Children's motion devices commonly utilize flexible metal springs or other flexible or resilient biasing elements to impart a bouncing or other cyclical type of motion. Such biasing components may suffer from a number of disadvantages, such as for example, high material costs leading to increased production expense, increased complexity of manufacturing and assembly, susceptibility to fatigue failure, loss of elasticity and material creep over time, environmental concerns with material treatment and finishing processes such as metal powder-coating, increased weight resulting in higher transport and handling costs, production and sourcing difficulties, etc.
Accordingly, it can be seen that needs exist for improvements to children's motion devices. It is to the provision of improved children's motion devices meeting these and other needs that the present invention is primarily directed.
SUMMARYIn example embodiments, the present invention provides improved children's motion devices in various formats that incorporate non-metal resilient biasing elements to impart a bouncing or other cyclical type of motion. In example embodiments, the one or more resilient biasing elements comprise a polymeric elastomer material, such as for example a thermoplastic polyester elastomer.

In the depicted embodiment, the base 20 comprises a substantially rigid oval ring-shaped support platform configured to support the device 10 on a floor or other generally flat support surface. In alternate embodiments, the base 20 may have a circular, square, rectangular, polygonal, U-shaped, or other regular or irregular geometric configuration or structure. In example embodiments, the base 20 may comprise one or more base segments permanently or semi-permanently coupled together into an assembly, for example a front segment, first and second side segments, and/or a back segment; or alternatively may comprise a single unitary component. The base 20 may be constructed of a molded plastic, metal, wood, composite, and/or other structural material(s) of construction. The base 20 may optionally comprise one or more non-slip feet or contact surface components on its lower surface, for stability and positioning on the support surface, and/or to prevent marring the support surface.
In example embodiments, the child-supporting portion 40 comprises a seat or support assembly configured for supporting a child therein or thereon. In the depicted embodiment, the child-supporting portion 40 includes a peripheral support ring 42 at least partially surrounding and supporting an inner sling or seat portion 44. In example embodiments, the peripheral support ring 42 comprises a substantially rigid structure, for example constructed of a molded plastic, metal, wood, composite, and/or other material(s), and the inner sling or seat portion 44 comprises a flexible and/or cushioned fabric or soft-goods construction affixed and supported at its periphery by the peripheral support ring. In example forms, the child-supporting portion comprises a headrest or head end portion 50, a seatback portion 52, a seat bottom portion 54, a footrest or foot end portion 56, and side bolsters or armrest portions 58, configured to comfortably and securely support and retain children of a range of sizes and developmental stages therein, for example ranging from infants to young children.
In example embodiments, at least one non-metal resilient biasing element 60 is operatively engaged between the base 20 and the child-supporting portion 40. The resilient biasing element 60 is preferably configured to enable and impart a bouncing or other cyclical type of motion (indicated by directional arrow M) to the child-supporting portion 40, along with a child seated or supported thereon, through a range of motion between a first or upper position (shown in solid lines in
In the depicted example embodiment, the resilient biasing element 60 comprises a curved molding or panel of polymeric elastomer material extending along at least a portion of the front and sides of the bouncer device 10, with its lower side affixed or attached to the front portion of the base 20 and its upper side affixed or attached to the foot end 56 of the child-supporting portion 40. One or more openings or cutout portions 65 are optionally formed in the panel of material of the resilient biasing element 60, with the remaining material of the resilient biasing element forming one or more generally vertical ribs or upright struts, for example a plurality of ribs or struts 72, 74, 76 extending in a pair of spaced arrays along each side of the resilient biasing element, having lower ends adjacent the base 20 and upper ends adjacent the child-supporting portion 40. As seen with reference to
A first resilient biasing element 160 is operatively coupled in torsional engagement between a first leg of the base 120 and a first leg of the peripheral support member 142 of the child-supporting portion 140, on one side of the device 110; and a second resilient biasing element 160 is operatively coupled in torsional engagement between a second leg of the base and a second leg of the peripheral support member, on the opposite side of the device.
In example embodiments, the resilient biasing elements 160 comprise a polymeric elastomer material, such as for example a thermoplastic polyester elastomer, providing substantial elastic resilience along a range of motion in compression and/or tension. In particular embodiments, the resilient biasing elements 160 comprise a DuPont™ Hytrel® thermoplastic elastomer. The resilient biasing elements 160 provide a resilient and elastically deformable connection between the child-supporting portion 140 and the base 120, allowing the child supporting portion to move through a bouncing or otherwise cyclical motion (indicated by direction arrow M). As the child-supporting portion 140 moves relative to the base 120, the inner and outer rings 162, 164 of the resilient biasing elements 160 rotate concentrically relative to one another, causing the ribs or fins 166 to twist and stretch, with the elastic resilience of their constituent material imparting a rotational return bias in a direction opposite the motion of the child-supporting portion (i.e., an upward bias in response to downward motion, or a downward bias in response to upward motion). The resilient biasing elements 160 optionally provide a progressive stiffness which increases in resistance and upward bias as the child-supporting portion 140 moves downwardly relative to the base 120. In example embodiments, the ribs or fins 166 extending between the inner ring 162 and the outer ring 164 of the resilient biasing elements 160 have a varying thickness and/or stiffness along their length, for example being thinner and less stiff toward their inner ends at the points of attachment with the inner ring, and becoming progressively thicker and more stiff toward their outer ends at the points of attachment with the outer ring.
The resilient biasing elements 1260 preferably comprise cords or bands of a polymeric elastomer material such as for example a thermoplastic polyester elastomer, and in particular embodiments a DuPont™ Hytrel® thermoplastic elastomer. In example embodiments, the resilient biasing elements 1260 comprise moldings formed by injection molding, blow molding or other molding processes, or are extruded, braided, woven or otherwise fabricated. First or upper ends of the resilient biasing cords 1260 are attached to upper cross-members of the upper frame arms 1226, 1228 adjacent upper corners of the device 1210, and second or lower ends of the resilient biasing cords are attached to the sides of the seat panel 1242. In alternate embodiments, the resilient biasing cords extend through the top of the seat panel. The resilient biasing cords 1260 may be provided in spaced arrays of two or more cords, for example in the depicted embodiment, four arrays of three cords each are provided, one array connected at each corner of the seat panel 1242. In alternative embodiments, fewer or more resilient biasing cords per array, and/or fewer or more arrays of cords may be provided.
The resilient biasing elements 1360 preferably comprise cords or bands of a molded polymeric elastomer material such as for example a thermoplastic polyester elastomer, and in particular embodiments a DuPont™ Hytrel® thermoplastic elastomer. First or upper ends of the resilient biasing cords 1360 are attached to upper cross-members of the upper frame arms 1326, 1328 adjacent upper corners of the device 1310, and second or lower ends of the resilient biasing cords are attached to the sides of the seat panel 1342. The resilient biasing cords 1360 may be provided in spaced arrays of two or more cords, for example in the depicted embodiment, four arrays of three cords each are provided, one array connected at each corner of the seat panel 1342. In alternative embodiments, fewer or more resilient biasing cords per array, and/or fewer or more arrays of cords may be provided. The resilient biasing cords 1360 may be detachably coupled to the upper cross-members of the upper frame arms 1326, 1328 by tube clips or brackets 1380 having a hooked coupling portion configured to securely engage the frame arms when the device 1310 is in use with a child seated therein, but to be detached by application of moderate hand pressure by an adult caregiver when the device is not in use and a child is not seated therein.
A sequence of folding the children's jumper device 1310 is depicted in
In use, a child is placed into or onto the child supporting portion of a children's motion device according to example embodiments of the invention, and a bouncing or other cyclical movement of the child supporting portion is imparted by manual application of force by an adult caregiver, by movement of the child, by an electronic motor-driven or electromagnetic auto-bouncer unit, and/or by other means. As the child supporting portion is moved in a first direction, the one or more non-metal resilient biasing elements of the device elastically and resiliently extend or contract out of equilibrium, either in tension or compression between the child supporting portion and the base. The shape-memory or elastic resilience of the material of the one or more non-metal resilient biasing elements causes the biasing elements to apply a biasing force to the child supporting portion, counter to the direction of motion of the child supporting portion. The counter-biasing force increases as the child supporting portion moves further out of its equilibrium position, until it balances and overcomes the momentum of the motion, causing the child supporting portion to reverse direction and move in an opposite second direction. The range of motion may then cycle back and forth in a bouncing, swinging or other form, providing entertainment, exercise, and/or soothing movement to a child supported in the motion device.
While the invention has been described with reference to example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
