TECHNICAL FIELD
The present invention relates generally to the field of children's accessories, and more particularly to motion devices for children.
BACKGROUND
Various 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.
SUMMARY
In 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 one aspect, the present invention relates to a children's bouncer device including a base configured to support the device on a support surface, a child-supporting portion supported above the base and configured to support a child, and at least one non-metal resilient biasing element operatively engaged between the base and the child-supporting portion to allow a bouncing motion of the child-supporting portion relative to the base. The resilient biasing element preferably includes a body formed of a polymeric elastomer material such as, for example, a thermoplastic polyester elastomer. The body preferably has a first side attached to the base, a second side attached to the child supporting portion, and at least one interconnecting member extending between the first side and the second side. The at least one interconnecting member preferably deforms elastically and resiliently and imparts a counter-biasing force on the child-supporting portion in response to the bouncing motion of the child-supporting portion.
In another aspect, the invention relates to a children's motion device including a base, a child-supporting portion, and at least one non-metal resilient biasing element operatively engaged between the base and the child-supporting portion to allow motion of the child-supporting portion relative to the base. The resilient biasing element is preferably formed from a thermoplastic polyester elastomer, for example by molding. In particular example embodiments, the thermoplastic polyester elastomer is a DuPont™ Hytrel® material.
In still another aspect, the invention relates to a children's jumper device including a base frame that includes a plurality of frame segments coupled to form a frame assembly, the frame assembly including lower frame legs and upper frame arms. The jumper device preferably also includes a child-supporting portion including a seat panel having an opening formed therein, and a seat sling having a pair of leg openings formed therein affixed to the seat panel and extending across and beneath the opening. The jumper device preferably also includes a plurality of non-metal resilient biasing elements suspending the child-supporting portion from the upper frame arms of the base frame and allowing a bouncing motion of the child-supporting portion relative to the base frame. The resilient biasing elements are preferably formed from a thermoplastic polyester elastomer material and are configured to elastically and resiliently deform under tension and provide a progressively increasing counter-biasing force during at least a portion of the bouncing motion of the child-supporting portion.
In another aspect, the invention relates to a chair including a base, a seat portion, and an attachment bracket operatively engaged between the base and the seat portion to allow a pivotal rocking or bouncing motion of the seat portion relative to the base.

With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views, FIGS. 1A-1D show a children's bouncer device 10 according to an example embodiment of the present invention. The bouncer device 10 generally comprises a base 20, a child-supporting portion 40, and at least one non-metal resilient biasing element 60 operatively engaged between the base and the child-supporting portion to allow a pivotal or bouncing motion M of the child-supporting portion relative to the base.
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 FIG. 1) and a second or lower position (shown in broken lines), while the base 20 remains generally stationary. In example embodiments, the one or more resilient biasing elements 60 comprise molded components formed from 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 one or more resilient biasing elements 60 comprise a DuPont™ Hytrel® thermoplastic elastomer. In alternate embodiments, the resilient biasing elements comprise other elastomers, polymers, composites, natural or synthetic rubber, metals, woods, or other materials providing a suitable degree of elastic deformation, and resisting plastic deformation, under intended loads and over the desired range of motion. In example embodiments, the resilient biasing elements 60 may be formed by various processes, for example formed as a molded body by injection molding, blow molding or other molding technique, extruded, cast, woven, or otherwise fabricated. The configuration of the resilient biasing element 60, including without limitation the material durometer or hardness, reinforcement components, the thickness and shape of the material, and/or the location(s) of placement between the base 20 and the child-supporting portion 40 are selected and designed depending upon parameters including the intended loading (e.g., weight range of child), and desired range of movement, speed and type of movement. In example embodiments, the resilient biasing element 60 is formed separately from the base 20 and the child-supporting portion 40, and the components are attached by adhesive, welding or bonding, and/or one or more coupling elements or attachment members. In alternate embodiments, the resilient biasing element 60 is formed together with the base 20 and the child-supporting portion 40, for example by co-molding or other fabrication process. In example embodiments, the material of the resilient biasing element 60 is of a bright or contrasting color differing in appearance from the material of the base 20 and the child-supporting portion 40, allowing improved external visibility of its flexure and elastic deformation as the device 10 bounces when used.
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 FIGS. 1C and 1D, the struts 72, 74, 76 optionally provide a progressive stiffness which increases in resistance and upward bias as the child-supporting portion 40 moves downwardly relative to the base 20, compressing successive portions of the material of the resilient biasing element 60. For example, as the child-supporting portion 40 begins to move downwardly relative to the base 20 (FIG. 1C), the first or taller strut 72 resiliently and elastically compresses and deforms, for example buckling inwardly into contact with the second or intermediate strut 74, and providing an initial degree of upward biasing force. As the child-supporting portion 40 continues to move further downwardly relative to the base 20, the first and second struts 72, 74 resiliently and elastically compress and deform together with an increasing degree of stiffness, for example buckling inwardly into contact with the third or shorter strut 76, and provide an additional greater degree of upward biasing force. And as the child-supporting portion 40 continues to move still further downwardly relative to the base 20 (FIG. 1D), the first, second and third struts 72, 74, 76 resiliently and elastically compress and deform together with a further increasing degree of stiffness, for example buckling inwardly into contact with a medial portion of the resilient biasing element 60, providing an even greater degree of upward biasing force. In alternative embodiments, the resilient biasing element 60 may comprise one, two, three or more resilient struts of various configurations arranged in one, two or more spaced arrays, or the resilient biasing element may comprise a continuous solid panel or molding of polymeric elastomer material. In further alternative embodiments, the thickness, shape, location, material hardness or durometer, or other characteristics of the different struts or different sections of the resilient biasing element 60 can be selectively varied to impart desired support and motion characteristics.
FIGS. 2A, 2B, 2C and 2D show a children's bouncer device 110 according to another example embodiment of the present invention. The bouncer device 110 generally comprises a base 120, a child-supporting portion 140, and at least one non-metal resilient biasing element 160 operatively engaged between the base and the child-supporting portion to allow a pivotal or bouncing motion M of the child-supporting portion relative to the base. In this embodiment, the base 120 comprises a U-shaped structure having first and second side arms and an interconnecting rear cross-piece, and the child-supporting portion 140 comprises a U-shaped peripheral support member 142 having a first side arm, a second side arm, and an interconnecting head end cross-piece. Example embodiments can also include a foot end cross-piece. Ends of the first and second side arms of the base 120 are pivotally coupled to respective ends of the first and second side arms of the peripheral support member 142. The child-supporting portion 140 further comprises an inner sling or seat portion 144 supported by the peripheral support member 142, and a toy or accessory bar 146 detachably connected to the peripheral support member and extending over the child seating area. An electronic accessory 150, such as for example a vibrational unit, auto-bounce motor, audio or audiovisual device, or other entertainment feature is optionally included. The device 110 is foldable from the assembled configuration shown in FIG. 2A to the folded and compact configuration shown in FIG. 2D, by means of a hinged connection between the base 120 and the child-supporting portion 140. The detachable toy or accessory bar 146 optionally comprises an inner channel or groove configured to slide over and onto the back of the base 120, as shown in FIG. 2D.
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. FIG. 2B shows additional details of the resilient biasing elements 160 according to an example embodiment. The resilient biasing element 160 comprises an annular body having an inner ring 162 configured for cooperative engagement with a hub 122 of a mounting flange portion of the base 120, a concentric outer ring 164 configured for cooperative engagement with a sleeve 148 on the peripheral support member 142 of the child-supporting portion 140, and a plurality of ribs or fins 166 extending radially between the inner and outer rings in a circumferentially spaced array. Abutting contact surfaces of the hub 122 and inner ring 162, and of the sleeve 148 and outer ring 164, respectively, optionally include interengaging surface features for positional fixation of the components relative to one another, which are further optionally releasable and repositionable to allow selective variation of the angle of incline of the child-supporting portion 140 relative to the base 120, and for folding of the frame of the device 110. The resilient biasing element 160 and the coupled ends of the arms of the base 120 and the support member 142 are retained in position by coupling elements, such as for example a threaded mounting flange 180, bushing 182 and correspondingly threaded nut 184.
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 jumper device 1310 generally comprises a base 1320, a child-supporting portion 1340, and at least one non-metal resilient biasing element 1360 operatively engaged between the base and the child-supporting portion to allow a bouncing and/or swinging motion of the child-supporting portion relative to the base. The base 1320 comprises a frame formed from an assembly of frame elements such as tubular sections of aluminum, steel, plastic, wood or other metals, polymers, composites or other materials. In the depicted example, the base frame 1320 comprises first and second generally downwardly extending U-shaped lower frame legs 1322, 1324, first and second generally upwardly extending U-shaped upper frame arms 1326, 1328, and two cross-frame couplings 1330 pivotally connecting the ends of the upper frame arms and the lower frame legs. The child-supporting portion 1340 comprises a seat panel 1342 having an opening formed therein, and a seat sling 1344 having a pair of leg openings formed therein affixed to the seat panel and extending across and beneath the opening.
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 FIGS. 14A-14D. As shown in FIG. 14A-14B, the tube clips 1380 are detached from one of the upper frame arms 1326 or 1328. The tube clips may remain attached to the other upper frame arm. The child-supporting portion 1340 is then free to move away from the detached upper frame arm, and does not interfere with its folding. The adult caregiver actuates a frame release actuator 1332 on one or both cross-frame couplings 1330, which releases the upper frame arms 1326, 1328 to be folded toward one another (FIG. 14C), and releases the lower frame legs 1322, 1324 to be folded toward one another (FIG. 14D). In the folded configuration, the upper frame arms 1326, 1328, lower frame legs 1322, 1324, and child-supporting portion 1340 are generally aligned with one another in a flat and compact configuration for ease of transport or storage.
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.
