Substrate-Retaining Holder
Apparatus and associated methods relate to a holder with a slot for laterally receiving and extracting a thin substrate into a recessed access area where a major surface of the substrate may be accessed while the edges of the substrate are substantially retained against vertical egress. In an illustrative example, the thin substrate may be paper or other material suitable for marking with a writing instrument. The access area in some examples may be defined by an opening in the holder through which a central area of the major surface of the substrate may be accessed. In an illustrative embodiment, the holder may be attached to a child's high chair to attract the child's attention and substantially confine the use of writing instruments to the paper disposed within the recessed access area.
Various embodiments described herein may relate generally to apparatus or methods for holding objects, such as paper.
BACKGROUNDPaper is a widely used substrate for recording written language as well as works of art. Authors and artists come in all ages, as even young children enjoy putting a writing instrument to express themselves creatively. Instruments such as paint brushes, crayons, pens, markers, or the like can be employed to make tangible creative expressions on a wide variety of surfaces.
Although paper is a common substrate for writing and drawing, other substrates can be used. For example, plastics can be used to make transparent surfaces.
Some surfaces may be considered more appropriate for marking than other surfaces. In addition to paper, people may wish to draw on surfaces such as chalkboards or grease boards. Examples of generally inappropriate surfaces for marking with writing instruments may include metals, fabrics, glass, or cement. It can be detrimental if writing instruments are applied to furniture, appliances, clothes, walls, or a range of ordinary household objects.
SUMMARYApparatus and associated methods relate to a holder with a slot for laterally receiving and extracting a thin substrate into a recessed access area where a major surface of the substrate may be accessed while the edges of the substrate are substantially retained against vertical egress. In an illustrative example, the thin substrate may be paper or other material suitable for marking with a writing instrument. The access area in some examples may be defined by an opening in the holder through which a central area of the major surface of the substrate may be accessed. In an illustrative embodiment, the holder may be attached to a child's high chair to attract the child's attention and substantially confine the use of writing instruments to the paper disposed within the recessed access area.
Various embodiments may provide one or more advantages. For example, certain embodiments may be useful as entertainment systems for children. Some embodiments may advantageously confine the drawings instruments of a child substantially to a benign writing surface (e.g., paper) within the recessed access area. Some embodiments may provide a portable or stationary entertainment station generally for use by a child confined to a seat for engaging the attention of the child such as to keep the child occupied. In some implementations the holder may be mountable to an object, such as a chair seat, a table top, or a vertical surface (e.g., wall). In some implementations, certain embodiments may be further capable of releasably retaining an object, such as an electronic notebook or tablet computer, providing a frame to hold and protect the object against abrasion, shock, or other impacts. Various examples may be deployed in stationary applications by attachment to a vertical or horizontal surface, for example. Some implementations may advantageously be integrated into other systems, such as, for example, in a children's high chair or a seat adapted for use in a vehicle (e.g., airplane, automobile, or marine craft). Some embodiments may also enhance drawing and writing within a confined region, thereby limiting occurrences of writing on inappropriate locations. Additionally, some electronic embodiments of the holder may include electronic circuitry capable of responding to user inputs, such as by recording user activity and/or providing predetermined outputs in response to the user input. Some embodiments may further be suited for protectively retaining an electronic tablet, book, or other thick medium or object.
The details of various embodiments are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.

Exposed surfaces may be readily cleaned by, for example, spray disinfectants and/or wiping, or by application of a detergent solution (e.g., spray, submersion). In some examples, the liner may be attached to the base member and/or frame or may simply be positioned within the access opening upon the upper surface of the base member.
At times especially younger children can be easily distracted and generally seek attention of either the individuals around them, or they may seek to engage some object, toy, person, or thing. If left unengaged, children may be subject to causing a mess, such as drawing on inappropriate surfaces. Various embodiments described herein may serve to engage children, such as for example while at a dinner table, when seated in a high chair, in a waiting room, while seated in a shopping cart, or while at various other times or locations where the child may benefit from constructive engagement (e.g., drawing) for a period of time.
In various examples, apparatus and associated methods may relate to an entertainment system for engaging the attention of the child while confined to a seat. The system may generally include a holder having an access opening defined by a raised frame and having a slot extending through one side of the frame for insertion/removal of a paper substrate to and from the frame. The inner edges of the frame may overhang the slot and retain the paper substrate within the slot to be accessed via the access opening. The child may draw upon the paper substrate while the frame restricts the child from drawing off of the paper substrate and upon the object that the holder is resting upon. Various attachment structures are also described for attaching the holder to objects, such as for example a table, a chair, and a shopping cart. The holder may also be suited for retaining electronic tablets or books.
In some examples, an entertainment system may be adapted for children. A portable or stationary entertainment station generally for use by a child confined to a seat to and may be for engaging the attention of the child such as to keep the child occupied. In an illustrative example, the entertainment system may include a holder having an access opening, the access opening defined by a raised frame having an insertion and removal slot extending through one side of the frame for insertion and removal of a paper substrate within the frame and centered with the access opening. The inner edges of the frame may overhang the slot and thus overhang the inserted paper substrate to retain the paper substrate to be within the slot and accessible via the access opening. The child may draw or write upon the restrained paper substrate while the raised frame restricts the child from drawing or writing off of the paper and upon the object that the holder is resting upon, such as for example a high chair table. Various attachment structures are also described for attaching the holder to objects, such as for example a table, a chair, and a shopping cart.
A number of implementations have been described. Nevertheless, it will be understood that various modification may be made.
