[0028] With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views, FIGS. 1-15 show example embodiments and modes of use of an adjustable bouncing frame 10 for a child support device D. The child support device D can be a children's walker, for example the children's walker shown in U.S. application Ser. No. 15/259,212 filed Sep. 8, 2016, the entirety of which is hereby incorporated herein by reference for all purposes. In other embodiments, the child support device D can be any device configured to support a child above a support surface S, including bouncers, entertainers, and strollers. In example forms, the adjustable bouncing frame 10 includes a support member or support members 20 extending between a support surface S, or base B of the device D, and a child support platform P. The adjustable bouncing frame 10 also generally includes a height-adjustment mechanism 40, shown in detail in FIGS. 2 and 3. In example embodiments, the adjustable bouncing frame 10 also includes a bouncing component 60 that allows the child seat platform P to resiliently bounce up-and-down relative to the support surface S in response to activity and movement of a child seated therein. In still other embodiments, the adjustable bouncing frame includes a bouncing component without a height-adjustment mechanism.

[0029] In the depicted embodiment, the support members 20 are comprised of first and second support members 22, 24 extending upward from the base B of the device D to support the child platform P. Generally, each support member 20 is slidingly coupled to either the base B or the support platform P at a first end and each support member is pivotally coupled to the other component of the device D at the second end. In the depicted embodiment, the first support arm 22 is pivotally mounted to the base B of the device D at a first end and attached to the height-adjustment mechanism 40 at a second end. The second support arm 24 is slidingly mounted to the base B at a first end and pivotally attached to the seat platform P at a second end. In other embodiments, the orientations of the first and second support members 22, 24 can be reversed.

[0030] In the depicted embodiment, the first and second support arms 22, 24 are connected at medial portions thereof by pivotal hubs 26, which allow the support arms to pivot and fold relative to one another. The upper front end of the first support member 22 is attached to the height-adjustment mechanism 40; the lower rear end of the first support member is pivotally coupled to rearward portions of the base B, as shown in detail in FIG. 4. The lower front end of the second support member 24 is slidably mounted to the forward portions of the base B; the upper rear end of the second support member is pivotally coupled to a rearwards portion of the seat platform P. In the depicted embodiment, the lower front end of the second support member 24 is slidably mounted within lower tracks or slots 28 extending laterally along the base B of the device D, as shown in FIG. 5. In other embodiments, other configurations of support members 20 can be used.

[0031] As shown in FIG. 3, the height-adjustment mechanism 40 generally includes a track 42 attached to the device D. The track 42 is configured to receive the end of a support member 20 that is slidingly attached to the device D. In the depicted embodiment, the track 42 is attached to the seat platform P. The first support arm 22 is slidingly coupled to the track 42 such that an end portion 30 of the first support arm is held between the track and the child platform P. Generally, the position of the end portion 30 of the first support arm 22 along the track 30 determines the height position of the child platform P. In other embodiments, the track can be attached to the base B or base component of the device D. The track 42 includes at least one stop surface or notch 44 configured to hold the end portion 30 of the first support arm 22 at a position along the track and thereby hold the child platform P at a prescribed height. In the depicted embodiment, the track 42 includes a series of stop surfaces 44, 44, 44 along its length. Each stop surface 44, 44, 44 is configured to correspond with a different height of the seat platform P.

[0032] In the depicted embodiment, the end portion 30 of the first support arm 22 is attached to a carriage 46 that is configured to slide laterally along the track 42. The carriage 46 includes at least one flange or tooth 48 configured to engage the stop surfaces 44, 44, 44 of the track 42. The carriage 46 generally includes a biasing or locking mechanism 52 that holds the flange 48 in engagement with a stop surface 42 until released by a caregiver that is adjusting the height of the device D. In the depicted embodiment, the track 42 includes an opening or slot 50 extending along a central axis of the track. The carriage 46 includes a knob 52 coupled to the bottom of the carriage and extending through the slot 50. The knob 52 is configured to releasably lock the carriage 46 in a position along the track 42. The knob 52 is dimensioned such that the width of the knob is larger than the width of the opening 50 in the track 42 such that when the knob is positioned perpendicular to the opening, the locked position, it cannot pass through the opening. The knob 52 is spring-biased towards the carriage 46 and thus holds the bottom of the carriage in engagement with the top of the track 42. In the depicted embodiment, the carriage 46 comprises a coil spring to bias the knob 52 toward the carriage. In other embodiments, other biasing or locking mechanisms can be used. In other embodiments, the end portion 30 of the first support member 22 slides directly along the track without the use of a carriage. The end portion 30 can be configured to engage directly with the stop surfaces 44, 44, 44 of the track 42.

[0033] The adjustable bouncing frame 10 of the depicted embodiment includes first, second, and third expanded modes, shown in FIGS. 6, 7, and 8, respectively, corresponding with the three stop surfaces 44, 44, 44. When the flange 48 of the carriage 46 engages the first stop surface 44, the frame 10 is held in a first expanded mode that holds the seat platform P at a first height, shown in FIG. 6 and FIG. 9A. When the flange 48 of the carriage 46 engages the second stop surface 44, the frame 10 is held in a second expanded mode that holds the seat platform P at a second height, shown in FIG. 7 and FIG. 9B. When the flange 48 of the carriage 46 engages the third stop surface 44, the frame 10 is held in a third expanded mode that holds the seat platform P at a second height, shown in FIG. 8 and FIG. 9C. As the carriage 46, and thereby the end portion 30 of the first support arm 22, is moved further along the track 42, the distance between the ends of the support arms 22, 24 is increased, lowering the height of the seat platform P of the child support device D.

[0034] In example embodiments, the spring-biased knob 52 acts as a locking mechanism to lock the frame 10 in an expanded position. In example embodiments, the knob 52 can be rotated, as shown in FIG. 11A, to a position parallel to the opening 50 in the track 42, the unlocked position, shown in FIG. 11B. To change the height of the seat platform P supported by the frame 10, a user twists the knob 52 from the locked position to the unlocked position, as shown in FIG. 10A. The user then pushes the knob 52 upward to force the flange 48 of the carriage 46 out of engagement with the stop surface 44. The carriage 46 can then be pushed laterally until the flange 48 engages the next stop surface 44 as shown in FIGS. 10B and 10C, thus moving the frame 10 from the first expanded position to the second expanded position. The same process is repeated to move the carriage 46 into engagement with the third stop surface 44, as shown in FIG. 10D. In other embodiments, the track 42 can include more or fewer stop surfaces to correspond to the desired heights of the seat platform P.

[0035] In example embodiments, the adjustable bouncing frame 10 also includes a bouncing component 60. The bouncing component 60 generally comprises a resilient member 62 that allows the sliding end, in this case the upper end 30, of the first support member 22 to move in a lateral reciprocal motion, as shown in FIGS. 12 and 13. The lateral, side-to-side motion of the upper end 30 of the first support member 22 moves the seat platform P in an up-and-down bouncing motion perpendicular to the support surface. In the depicted embodiment, the resilient member 62 is positioned in the carriage 46 of the height adjustment mechanism 40 such that the seat platform P has the same bouncing motion in each of the plurality of expanded modes. In other words, the range of bouncing motion of the seat platform P remains the same as the height of the seat platform P is adjusted.

[0036] As shown in detail in FIG. 3, the carriage 46 generally includes a first end 64 and a second end 66. The carriage 46 also comprises a track 68 running along the bottom of the carriage between the first end 64 and the second end 66. The upper end 30 of the first support member 22 is slidingly coupled to the carriage 46 such that the upper end 30 can slide laterally along the track 68. The upper end 30 of the first support member 22 is biased towards the first end 64 of the carriage 46. The resilient member 62 is positioned between the upper end 30 of the first support member 22 and the second end 66 of the carriage 46 to bias the upper end toward the first end 64 of the carriage. In the depicted embodiment, the resilient member 62 is a coil spring, for example formed of steel or other metal. In other embodiments, the resilient member 62 can be formed from any resilient, deformable material including rubber, foam, or polymeric materials such as for example DuPont Hytrel. Different strength springs can be used depending on the desired degree of bounce. In different embodiments, the length of the carriage can be adjusted to determine the bounce height. In the depicted embodiment, the track 42 and carriage 46 move in a lateral motion parallel to the support surface. In other embodiments, the track and/or carriage can move at an angle relative to the support surface.

[0037] In use, the resilient member 62 holds the upper end 30 of the first support member 22 at the first or rear end 64 of the carriage 46 as show in FIG. 12B. This holds the seat platform Pat its maximum height, as shown in FIG. 12A. When a force is applied to the seat platform P, the resilient member 62 compresses to allow the upper end 30 of the first support member 22 to move laterally towards the second or front end 66 of the carriage 46, as shown in FIG. 13B. The forward lateral motion of the upper end 30 of the first support member 22 pulls the seat platform P down to temporarily reduce the height of the seat platform, as shown in FIG. 13A. The snap of the resilient member 62 creates a reciprocal motion that causes the seat platform P to bounce for a period of time before returning to its original height. The bottom end of the second support member 24 is able to slide along the track 28 in the device base B to accommodate the change in height of the seat platform P. The entire carriage 46 moves along the track 42 as the height of the device D is adjusted. Therefore the degree of bounce of the frame 10 remains the same in each of the expanded modes of the frame.

[0038] The carriage 46 optionally includes a carriage cover 70 configured to fit over the top of the carriage. The carriage cover 70 is configured to help protect the components within the carriage as it moves along the track 42. In other embodiments, the carriage 42 can include a locking mechanism configured to hold the upper end 30 of the first support member in place at the first end 64 of the carriage 42, thereby preventing the bouncing motion of the seat platform P. The locking mechanism could be activated or deactivated using a user input, for example a button or lever. Thus the caregiver would have the option to allow the child device D to bounce or hold the seat platform P at a prescribed height.

[0039] In other embodiments, the frame 10 can include a bouncing component 40 but not a height adjustment component. In this example embodiment, the upper end of the first support member is slidably attached directly to a track that is attached to a child seat platform. The track includes a resilient member configured to restrict the lateral movement of the upper end of the first support member. In other embodiments, the coupling between the device D and the second support member 24 can also include a bouncing component to allow a child within the device to receive a receptacle bounce. In other embodiments, the height-adjustment mechanism and/or bouncing component are positioned on the base of the child support device.

[0040] In example embodiments, the support frame 10 is collapsible to a compact position for storage or transport when not in use, as shown in FIGS. 14 and 15. To move the device D to the storage position, the height adjustment mechanism 40 is moved to the unlocked position and the upper end 30 of the first support member 22 is moved towards the front end of the track 42. The bottom end of the second support member 24 also moves toward the front end of the slot 28 in the base B of the device. This movement shortens the vertical distance between the base B of the device D and the seating platform P to lower the dimensions of the device for packaging and storage.

[0041] 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. For example, the use of the adjustable bouncing frame of the present invention is not limited to child support device. The frame can be used in any device where adjustment of device height and/or bounce is desired. Moreover, the particular configurations, materials of construction, and objectives described herein are merely exemplary and are in no way limiting.
