A support apparatus includes: a first support member; a second support member rotatably connected to the first support member and capable of rotating within a first angle range starting from a position where the first support member is located; and a third support member rotatably connected to the second support member and capable of, after the second support member rotates to a maximum angle thereof, continuing to rotate in a direction in which the second support member rotates within a second angle range starting from a position where the second support member is located. The second angle range is greater than or equal to the first angle range.

A clipboard system comprising a clipboard that cooperates with a case of a portable computing device (e.g., a tablet computer) such that the case attaches to the clipboard to enable interchangeable usage of the portable computing device and the clipboard. The case enables the portable computing device to be enclosed and supported, and utilized while coupled with the clipboard. The case receives the computing device and secures the device therein, while exposing the device display and the device controls for user interaction. The case comprises a backside having affixed thereto an attachment material such as one part of a two-part fastener that securely interfaces to the other part of the fastener material affixed to the clipboard. The attachment material is of sufficient strength to hold the case and enclosed computing device to the clipboard during normal usage.

In various implementations, furniture, such as a table (e.g., a desk) and/or free-standing board, may include an organizational frame to which other members (e.g., table top, white board, smart board, etc.) may be coupled. The frame may include legs and at least one organizational member disposed between two or more of the legs. The organizational member may include a plurality of openings. The opening(s) in the organizational member may be able to couple with one or more organization tools.

A multi-positional easel allows for a wider range of motion for a work platform, accommodating both seated and standing positions, as well as full tilt and rotation of the work platform. The characteristics of this easel consist of a work platform that can expand to hold various sizes of canvas or other work pieces. These work pieces are held in place by four adjustable points, two on each side. A free standing three-point wheeled base has a single adjustable vertical post. Attached to that post is a multi-positional armature assembly that allows for more flexibility in the positioning of the work platform. Once the work piece is held in place on the work platform, the work platform can be rotated in a plane in a full 360-degrees, as well as a free range of motion of tilt from a horizontal plane to a vertical plane.

A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when actuated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A lever-locking mechanism or a twist-lock mechanism secures the device in place against or within a door frame and against the door.
