(11) With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views, FIGS. 1A-1K illustrate a height-adjustable child support device 100 according to a first example embodiment of the present invention. As shown in FIGS. 1A and 1B, the child support device 100 includes a base member 110 that is adapted to rest on a support surface, e.g., the floor. The child support device also includes upright frame members 120 ascending from the base member 110. In example embodiments, the base 110 comprises a generally ring-shaped assembly defining a generally circular, square, rectangular or polygonal periphery, and the uprights 120 are radiused or tapered, for example tapering generally outwardly at lower portions proximal the base and back inwardly at upper portions near their top free ends. Connection hubs are optionally provided to attach the uprights 120 at spaced locations about the base 110. Support members 130 are movably coupled to the upright frame members 120. Although four support members 130 and four upright frame members 120 are shown for illustrative purposes, it should be appreciated that there may be any number of support members 130 and corresponding upright frame members 120. The support members 130 described with respect to this embodiment and other embodiments described herein can take the form of bungee cords, rubber straps, springs, or other elastic elements; or alternatively can comprise lengths of rope, cord or other flexible material with or without elasticity.

(12) The child support device includes a seat assembly including a seat tray 140 and a seat 145 having a pair of openings for receiving an infant's or child's legs when an infant or child is arranged in the seat and an entertainment tray surrounding the seat. In example embodiments, the seat 145 is positioned in an opening generally centrally in the seat tray 140, and the legs of a child supported in the seat extend though the seat openings allowing the child's feet to contact the ground or other support surface. In this manner, the child can jump and bounce within the child support device 100, with the resilience of support members 130 providing an entertaining oscillation or bouncing motion. The seat tray 140 optionally comprises one or more child entertainment features, such as for example a toy, a character, a mobile, a motion device, an electronic audiovisual device, a sound-generating device, a light, a cup-holder, a rattle, a grasping element, a teether, or the like. Optionally, the seat 145 for receiving and positioning a child therein is rotationally mounted to the seat tray 140, so that the child can turn to face different directions while seated therein. Alternatively, the tray 140 can rotate about the seat 145. For example, the tray 140 could comprise a stationary bottom tray which the support members 130 may be coupled to and a rotatable upper tray. The seat tray 140 is suspended from the frame members 120 by the support members 130 extending above the seat tray. A height of the seat tray 140 is vertically adjustable (direction arrow H) by moving a position of one or more of the straps 130 with respect to a corresponding upright frame member 120. FIG. 1A shows the seat tray 140 in a lower position, and FIG. 1B shows the seat tray in a higher position

(13) The uppermost end of each upright frame member 120 includes a cap member 150. As shown in detail in FIGS. 1C, 1D, 1E, and 1F the cap member 150 includes a guiding channel 155 extending therethrough. A distal end of the support member 130 ascends from the seat tray 140 and can be threaded to emerge in a downward direction with respect to the cap 150. As shown in FIG. 1G, the cap portion 150 includes detachable or removable components 152 and 154, allowing access for threading of the support member 130 through the guiding channel 155 during assembly. The distal end of each support member 130 includes a coupling component 160 attached thereto. As shown in FIGS. 1B, 1C, 1D, 1E, the coupling component 160 is adapted to engage with a receiving component 170 located on the upper portion of the upright frame member 120.

(14) The coupling component 160 is shown in more detail in FIGS. 1H and 1I. As shown in these figures, the coupling component 160 may include a tab 162 with a pair of smaller transverse slots 164 through which a support member 130 is threaded, and a larger axially extending slot 166 configured to fit over an upright frame member 120 and allow the coupling component to slide up and down along the upright frame member. The receiving component 170 is shown in more detail in FIGS. 1J and 1K. The receiving component 170 can be mounted to or integrally formed with the upper portion of the upright frame member 120. The receiving component 170 can have a plurality of receiving sites, each presenting a different height or length. Each receiving site includes a notch (or slot) 175, and the tab 162 on coupling component 160 is adapted to engage with the notch. As shown in FIG. 1A, positioning the coupling component 160 of the support member 130 into engagement in a higher notch 175 of the receiving component 170 allows a longer length of the support member 130 to extend between the cap 150 and the seat tray 140, positioning the seat tray in a lowered position closer to the floor or other support surface, for example to use with a smaller child. And as shown in FIG. 1B, positioning the coupling component 160 of the support member 130 into engagement in a lower notch 175 of the receiving component 170 retracts the support member 130 resulting in a shorter length of support member extending between the cap 150 and the seat tray 140, positioning the seat tray in a raised or elevated position further from the floor or other support surface, for example to use with a larger child.

(15) In the embodiment of FIGS. 1A-1K, tension from the weight of the seat 145 (and a child supported therein) and the seat tray 140 retains the tab of the coupling component 160 in the notch of the receiving component to maintain the position of the seat tray 140 at a selected height adjustment. The coupling component 160 optionally toggles or pivots under load, about a fulcrum at the point of engagement with a notch 175 of the receiving component 170, to more securely engage the upright support member 120 within the axial slot 166 of the coupling component. By moving the coupling component 160 upward or downward to engage with one of the receiving sites of the receiving component 170, the length of the support member 130 extending between the cap member 150 and the seat tray 140 can be varied, thereby adjusting the height of the seat tray 140. In the depicted embodiment, the height adjustment components (coupling component 160 and receiving component 170) extend and retract the support members 130 to adjust the height of the seat tray 140 from positions above (i.e., at a higher elevation) the seat tray, and can be easily accessed and operated from a position on the exterior of the upright frame members 120 opposite the seat tray. While the seat tray 140 may in some instances be positioned at an elevation above the position of the coupling component(s) 160 and/or a portion of the receiving component(s) 170, the engagement of the support members 130 through the caps 150 or otherwise engaged at or around upper portions of the upright frame members 120 adjusts the height from a position above the seat tray.

(16) FIGS. 2A-2C illustrate a child support device 200 according to a second example embodiment. The child support device 200 shown in FIG. 2A is similar to that shown in FIG. 1A, in that it includes a base portion 210, upright frame members 220 extending therefrom, support members 230 coupled to the upright frame members 220, and a seat assembly including a seat 245 and a seat tray 240 movably supported by the support members. As shown in FIGS. 2A-2C, the distal end of each upright frame member 220 includes a cap member 250 through which the support member 230 is threaded. In addition, a coupling component 260 included at a distal end of each support member 230 is adapted to engage with a receiving component 270 that is mounted to or integrally formed with the upper portion of the upright frame member 220. As shown in FIGS. 2A-2C, the receiving component 270 can have a plurality of receiving sites, each including a notch or slot 275, and each presenting a different height adjustment setting for extending or retracting the length of the support members 230 between the caps 250 and the seat tray 240. By moving the coupling component 260 upward or downward to engage with different receiving sites along the receiving component 270, the length of the support member 230 extending between the cap member 250 and the seat tray 240 is lengthened or shortened, respectively, thereby adjusting the height of the seat tray 240 lower or higher. FIGS. 2B and 2C show further detail of the coupling component 260 receiving component 270. The coupling component 260 includes a spring-biased tab member 262 or actuator housed at least partially within a shell 264, the tab member 262 having an edge 266 adapted to be received in one of the plurality of notches (or slots) 275 of the receiving component 270. When a caregiver pushes the exposed end 268 of the tab 262 member into the shell 264, the spring 265 is compressed, and the edge 266 of the tab 262 is freed from the notch 275. A caregiver can then slide the coupling component 260 up or down the upright frame member 220 and release the tab member 262 into a notch 275 of the receiving component 270 at a desired height, thereby adjusting the height of the seat tray 240.

(17) FIG. 3A shows a child support device 300 according to another example embodiment. The child support device 300 is similar to that shown in FIGS. 1A and 2A, in that it includes a base portion 310, upright frame members 320 extending therefrom, support members 330 coupled to the upright frame members 320, and a seat assembly including a seat 345 and a seat tray 340 movably supported by the support members. Also, as shown in FIGS. 3A-3C, the distal end of each upright frame member 320 includes a cap member 350 through which the support member 330 is threaded. In addition, a coupling component 360 included at a distal end of each strap 330 is adapted to engage with a receiving component 370 that is mounted to or integrally formed with the upper portion of the upright frame member 320. As shown in FIGS. 3A-3C, the receiving component 370 can have a plurality of receiving sites, each including a protuberance 375, in a spaced array along a portion of the length of each upright 320, each presenting a different height or length adjustment setting. By moving the coupling component 360 upward or downward to engage with one of the receiving sites, the length of the support member 330 extending between the cap member 350 and the seat tray 340 can be varied, thereby adjusting the height of the seat tray 340. The protuberance included at each receiving site may include a peg or hook. As shown in detail in FIGS. 3B-3D, the coupling component 360 engages one of the protuberances 375 of the receiving component 370 by fitting over the selected protuberance corresponding to a desired height setting. As further shown in FIGS. 3C and 3D, the coupling component 360 and the receiving component 370 can be configured in such a way that the coupling component 360 can disengage from the receiving component 370 only when the coupling component is turned in a certain direction, thus biasing the coupling component 360 to a locked position when the weight of a child or infant is applied to the seat tray 340. For example, each protuberance 375 of the receiving component 370 can comprise an irregular key shape aligned axially with the upright 320, and the coupling component 360 can comprise an opening having a corresponding irregular keyway shape aligned transversely on the coupling component, whereby the key passes through the keyway when the coupling component is turned transversely but does not pass through the keyway when turned axially. In example embodiments, the support member 330 is attached to the coupling component 360 at an axial end thereof, such that when the coupling component is released and the support member tensioned, the coupling component does not disengage from the receiving component 370.

Support members 730, which may include, e.g., elastic support members or straps, suspend and support a seat assembly including a seat 745 and a seat tray 740 from a plurality of support couplings 770 located toward the upper portion free ends of each upright 720. In the depicted embodiment, the plurality of support couplings 770 comprise a spaced array of hooks or connectors 764 to which a loop or other connecting feature (not shown in detail for simplicity of illustration) of the supporting member 730 can releasably couple. Coupling the support member 730 to an upper one of the plurality of support couplings 770 positions the seat tray 740 at a higher position 740 as shown in solid lines, while coupling the support member 730 to a lower one of the plurality of support couplings positions the seat tray 740 at a lower position 740 as shown in broken lines, thereby allowing selective height adjustment of the child support device 700 as indicated by direction arrow H.

(23) FIG. 8 shows another example embodiment of a child support device 800 according to an example embodiment of the invention. The child support device 800 includes a frame having a base 810 and a plurality of uprights 820. Support members 830, which may include, e.g., elastic support members or straps, suspend and support a seat assembly including a seat 845 and a seat tray 840 from attachment points adjacent the upper portion free ends of each upright 820. In the depicted embodiment, the uprights 820 include telescoping or otherwise extensible upper members 822 that can be raised and lowered to a plurality of different heights to selectively position the seat tray 840 at a higher position 840 as shown in solid lines, or at a lower position 840 as shown in broken lines, thereby allowing height adjustment of the child support device 800 as indicated by direction arrow H.

(24) In another aspect of the invention, in any of its various embodiments, the child support device enables a method of allowing an adult caregiver to selectively adjust the height of the seat tray or other child support between two or more different elevations or height positions relative to the floor, ground or other support surface. In example embodiments, the method of the present invention comprises selectively positioning a point of contact of a support member of the child support device with an upright frame member of the child support device, at one of a plurality of positions, each of the plurality of positions corresponding to a different height or elevation of the seat tray. The point of contact of the support member with the upright frame member can be varied by repositioning a coupling component attached to the support member relative to a receiving component of the upright frame member, for example to vary the effective length of the portion of the support member extending between the upright frame member and the seat tray, thereby adjusting the height of the seat tray. For example, the support member can be extended or retracted by passing a middle portion of the support member through a passage in a cap at or near the top of the upright frame member and affixing a distal end of the support member at a selected position on the upright frame member, to selectively position the proximal end of the support member which is attached to the seat tray. Alternatively, the point of contact of the support member with the upright frame member can be varied by repositioning the point of attachment of the support member up or down on the upright frame member. In still other alternate embodiments, the point of contact of the support member with the upright frame member can be varied by repositioning at least an upper end portion of the upright frame member that contacts or attaches with the support member up or down. In example embodiments, the height adjustment is actuated by repositioning one or more features of the child support device located at an elevation above the seat tray, for example at or adjacent the upper portions of the upright frame members.

(25) Various changes and modifications to such a height adjustment device, beyond those explicitly mentioned herein, are contemplated as being within the scope of the present invention. For example, while the receiving components and coupling components have been variously described as notches, slots, protuberances and hooks, it should be appreciated that any fastening and retaining methods known in the industry may be used. 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. The particular configurations and objectives described herein are merely exemplary and are in no way limiting.

(26) While the invention has been described with reference to preferred and 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.
