20110198905 | Infant Support Structure - A bouncing seat for a child includes a seat support having an opening for receiving the child, a base, a post connected to and extending upwardly from the base, and first and second arms extending outwardly from a distal end of the post. The first and second arms are connected to the seat support, thereby connecting the seat support to the base. The post is aligned with the opening. | 08-18-2011 |
20110225737 | Power Source Compartment for an Infant Support Structure - An infant support structure includes a frame and a receptacle configured to receive a power source. The frame includes a hub and an infant support portion coupled to the hub. The hub defines the receptacle. A cover is coupled to the hub and is pivotally movable between an open position for providing access to the receptacle and a closed position for restricting access to the receptacle. The cover defines a handle portion for moving the infant support structure. | 09-22-2011 |
20130285421 | Children's Tray with Placement Indicator - A children's tray with a placement indicator includes a tray and a groove/spot formed in the tray to indicate where an eating item (including food, utensils, or dishware) is to be placed. The tray can be mounted, removably or fixedly, to a variety of child support structures, including high chairs, booster seats and bouncers and includes a wall around the periphery intended to prevent items from falling off of the tray. The groove/spot formed in the tray may be formed from of a material having a higher coefficient of friction than the material used to form the tray.
