    DETAILED DESCRIPTION

    [0039] FIG. 1 is a schematic diagram illustrating a perspective right view of an embodiment of an infant rocking seat in an expanded configuration, according to some embodiments of the present disclosure. The infant rocking seat of the present disclosure includes the base portion or a u-shaped bottom frame 26a. A middle portion or u-shaped recline bar 25a has arcuate legs extending to, and pivotally attached to, an underside 8 of the upper portion or a u-shaped seat frame 27a that is covered with a fabric 3. The upper portion or the u-shaped seat frame 27a is maintained at an acute angle with respect to the base portion or u-shaped bottom frame 26a. The angle of the upper portion or the u-shaped seat frame 27a is maintained by the middle portion or the u-shaped recline bar 25a that engages with detents defined and located on top of the recline mechanisms. Each recline mechanism is positioned opposite from the other, attached to the base portion or the u-shaped bottom frame 26a. The angle of the upper portion or the u-shaped seat frame 27a may be adjusted by repositioning the middle portion or the u-shaped recline bar 25a in another detent. The middle portion or the u-shaped recline bar 25a may be rotated away from the detents in order to fold the upper portion or the u-shaped seat frame 27a into a flat collapsible configuration.

    [0040] The motion mechanism or an electronic mechanism 28a is mounted to the back end 26c of the base portion or the u-shaped bottom frame 26a. The motion mechanism or an electronic mechanism 28a includes a motorized plunger 28d configured to oscillate and cause the upper portion or the u-shaped seat frame 27a to impart a rocking motion. The motion mechanism or an electronic mechanism 28a may have a control panel 28b with capacitive touch controls, wherein the motion mechanism or an electronic mechanism 28a may be rotated so that the plunger 28d does not contact the ground in case manual rocking is desired. The upper portion or the u-shaped seat frame 27a may include a remote-control device in communication with the electronic mechanism.

    [0041] The infant rocking seat or rocker 100 have components including a frame with an upper portion 27a (or a seat for an infant) with a bottom end 27b and a top end 27c positioned along a y-axis (see 40b in FIG. 3). A base portion 26a has a front end 26b and a back end 26c positioned along an x-axis (see 40a in FIG. 3). The bottom end 27b of the upper portion 27a hinges 19a, 19b (see FIG. 2) on the front end 26b of the base portion 26a. The infant rocking seat is configured to keep the infant comfortable, occupied with toys, and safe and secure. The infant has the option of bouncing along with being able to have the upper portion recline at multiple settings (or reclining angles), so the infant can sit, play, relax, etc.

    [0042] An infant securing system to secure an infant or child to the upper portion (i.e., where the infant/child sits or sleeps), includes a T-strap binding 2a, a T-shaped cover 2b, a shoulder strap 2c (see FIG. 6), a crotch strap 2g, buckles 2d (see FIG. 6), and a five-point harness 2e. The infant securing system allows the infant or baby to have two modes in one: bouncing and rocking. The 5-point harness keeps the infant/baby securely in place and the removable hot air balloon toy provides a fun and play option.

    [0043] Other features include the one or more recline mechanisms 24a, 24b (see FIG. 2) directly attached or fixed to the sides of the base portion 26a, and each recline mechanism 24a, 24b includes a release device 35a, 35b (see FIG. 2). The release devices 35a, 35b positioned on the outer surface of the recline mechanisms 24a, 24b are operable to disconnect the bottom segment 25d of FIG. 3 from the reclining mechanism.

    [0044] The upper portion 27a is coverable with fabric 3 and includes a seat pad 1, where the fabric has channel stitching 4. The upper portion 27a has a toy bar 7a, a toy bar connector 7b, a toy strap 7c connected to a hot air balloon toy 7d configured on the left side of the infant rocking seat.

    [0045] A remote-control device 33a to the motion mechanism (i.e., auto-rock housing unit) 28a (see FIG. 3) can be detachable to the frame, including the upper portion 27a on the right or the left side. It is contemplated that the remote-control device 33a can be located on the back 8 (see FIG. 3) of the upper portion 27a, if so desired by the user. The remote-control device 33a is in communication with the motion mechanism 28a located on the back end 26c of the base portion 26a to allow for a remote operation of one or more controls of the motion mechanism 28a. The base portion includes feet 21a, 21b (see FIG. 2) that can provide an additional stabilizing effect to the frame.

    [0046] FIG. 2 is a schematic illustrating a perspective left view of FIG. 1 of the infant rocking seat in an expanded configuration, according to some embodiments of the present disclosure.

    [0047] Referring to FIG. 1 and FIG. 2, the bottom end 27b of the upper portion 27a hinges 19a in FIG. 1, 19b in FIG. 2 on the front end 26b of the base portion 26a, as noted above. A top proximal end 25c (see FIG. 3) of a middle portion (i.e., a reclining bar) 25a is pivotably attached to the upper portion 27a (see FIG. 3). The reclining mechanisms 24a in FIG. 1, 24b in FIG. 2 are positioned opposite to each other on sides of the base portion 26a, each recline mechanism 24a, 24b is configured with detents to engage with a bottom segment 25d (see FIG. 3) of the middle portion or bar 25a. A locking mechanism configured within each recline mechanism 24a, 24b locks the bottom segment 25d of FIG. 3 in a detent. A lock-out mechanism configured in each recline mechanism 24a, 24b is structured to prevent the bottom segment 25d of FIG. 3 from unlocking which could cause the middle portion 25a to rotate away from the detent to transition with the frame from an expanded configuration as viewed in FIG. 1 and FIG. 2 into a collapsed configuration as viewed in FIG. 8.

    [0048] The release devices 35a in FIG. 1, 35b in FIG. 2 positioned on the outer surface of the recline mechanisms 24a, 24b are operable relative to the reclining mechanism (see 27a of FIG. 3) to disconnect the bottom segment 25d of FIG. 3 from the reclining mechanism located within each recline mechanism. Operating a release device 35a of FIG. 1, 35b of FIG. 2 on the recline mechanism(s) 24a, 24b, actuates the reclining mechanism adjustability. Specifically, activating the reclining mechanism allows the bottom segment 25d of FIG. 3 to release from a detent, and be readjusted to another detent allowing for a different reclining angle for the upper portion 27a (where the infant/child is playing, resting or sleeping) that is within the reclinable range of 90 degrees to 0 degrees (or in a horizontal position along the x-axis).

    [0049] Alternatively, the upper portion 27a can have a toy bar 12a, a toy bar connector 12b, a toy strap 12c connected to a hot air balloon toy 12d configured on the right side of the infant rocking seat 100.

    [0050] FIG. 3 is a schematic diagram illustrating a perspective rear view of FIG. 1 of the embodiment of an infant rocking seat in an expanded configuration, according to some embodiments of the present disclosure.

    [0051] Referring to FIG. 1, FIG. 2, and FIG. 3, each release device 35a in FIG. 1, 35b in FIG. 2 is positioned on an outer surface of the reclining mechanisms 24a, 24b in a location accessible to a user or parents. The design and development of structuring and arranging the release devices 35a, 35b location and operability was based on extensive engineering, testing, retesting, and more retesting, to ensure maximum safety and durability in operating the reclining mechanism to prevent any sudden or unexpected collapses of the infant holding apparatus. Other engineering and best practices incorporated into the release devices 35a, 35b were the ease of use and accessibility for parents to operate both devices. Specifically, simultaneously operating both release devices resulted in additional safety for the parents and children.

    [0052] Other features include the reclining mechanisms 24a, 24b directly attached or fixed to the base portion 26a, allowing additional structural integrity to the infant rocking seat. Another feature is the upper portion 27a is coverable with a fabric 3 with a seat pad 1.

    [0053] The infant rocking seat can be referred to as one or more terms or phrases including a Keep in Motion Auto Rocker an infant apparatus, a child apparatus, a foldable apparatus, a foldable device, a foldable infant device, a foldable baby device, a foldable child device, an infant supporting device, or a foldable infant rocking apparatus.

    [0054] FIG. 4 is a schematic diagram illustrating a front view of the auto-rock housing Unit (motion mechanism), according to some embodiments of the present disclosure. The auto-rock housing unit 28a is rotatably attached to the back end 26 of the base portion 26a. In particular, the auto-rock housing unit 28a houses a motorized plunger 28d configured to oscillate and cause a rocking motion to the upper portion 27a in a direction from the bottom end 27b to the top end 27c (see FIG. 1 and FIG. 2) along the x-axis (see 40a in FIG. 3). Specifically, the motion mechanism provides a rocking motion to the upper portion where the infant rests or sleeps to experience the rocking motion.

    [0055] A feature of the motion mechanism 28a is its ability to rotate by the user, where the importance of the adjustability was discovered during testing, leading to the later realization of expanding the operational use to allow parents to position the infant rocking seat on many different ground surfaces with effecting its operation. For example, if the motion mechanism were positioned on the ground that resulted in contacting the ground surface, it is possible the motion mechanism may not operate correctly preventing or disturbing the intended rocking motion, and it is possible issues may result. However, the ability to rotate and adjust the motion mechanism expands its use allowing it to operate on varying ground surfaces including linear and non-linear incline and decline ground surfaces.

    [0056] Another feature of the motion mechanism is the motorized plunger that provides an oscillating effect resulting in the upper portion (where the infant rests or sleeps) simulating a rocking motion from the front end to the back end along the x-axis in a linear direction of motion.

    [0057] Because the motion mechanism is rotatable in the vertical plane such that the user may move the motion mechanism upward to allow the human or parent to provide a manual rocking motion to the infant rocking seat of the present disclosure.
