Portable tripod support for portable keyboard device

A portable adjustable-height folding tripod support for a keyboard device for a seated user of the device,

• the support comprising a spider-like platform with foldable support arms having relatively folded compact storage and unfolded coplanar support positions with said support arms when unfolded having upper flat coplanar surfaces at their outer ends for attachment to a flat underside of the keyboard device,
• said platform including fastener means on said flat coplanar surfaces for releasably securing said support arms to a flat underside of the keyboard device,
• said tripod support including a tripod having three legs, each leg having an upper main leg member and at least another adjustable telescoping member for leg length adjustment,
• said tripod having a head and means for pivotably connecting said head to the upper ends of the upper main leg members to enable folding said tripod legs between outer unfolded support positions and folded stored positions,
• means for releasably connecting said platform to the tripod head,
• said tripod including means connected to the tripod legs to fix their outer unfolded positions and including a foldable three-arm support structure having outer ends of the three-arm support structure pivotably connected to the lower ends of respective main leg members,
• said three-arm support structure including a flat yoke member pivotably interconnecting the inner ends of the three support arms,
• said support arms and said yoke member having upper flat surfaces in a common plane and providing a knee-height platform for user accessories when the tripod legs are unfolded.

A portable adjustable-height folding tripod support for a keyboard device for a seated user of the device,

• said tripod support for the keyboard device including a tripod having three legs, each leg having an upper main leg member and at least another adjustable telescoping member for leg length adjustment,
• said tripod having a head, and hinge means for connecting said head to the upper ends of the upper main leg members,
• said head having an upper surface,
• said tripod support including securement means for releasably connecting a keyboard device to the upper surface of said head whereby the keyboard device is canted at a fixed angle from horizontal when the tripod legs are of equal lengths and resting on a horizontal surface whereby the cant of the keyboard device is adapted to be canted in a direction toward the user by selective positioning of the tripod relative to the user to provide an ergonomically improved angle of operation for the keyboard of a keyboard device supported on the tripod support.

A portable support for attachment of a keyboard device having a flat underside to a stable structure,

• the portable support comprising a spider-like platform having a hub with a plurality of foldable cantilevered support arms extending relative to the hub and movable between relatively folded storage positions and unfolded generally coplanar hub-supported device-supporting positions,
• each arm having an elongated integrally formed bar forming the body of the arm and having at its inner end a pair of parallel outwardly facing side surfaces where the inner arm end extends and is pivotably supported between a pair of outwardly extending parallel opposed faces on integrally formed portions of the spider hub,
• the inner end of each bar having in its unfolded position of use a downwardly and inwardly extending end surface abutting an outwardly and downwardly facing surface of the hub to prevent the respective arms from swinging downwardly beyond their extended generally coplanar positions of use,
• said support arms when unfolded for use having integrally formed portions defining free upper upwardly-unobstructed flat coplanar surfaces at the outer ends of the bars for attachment to a flat underside of the keyboard device,
• said platform including fastener means on the flat coplanar surfaces on the ends of the unfolded support arms for releasably securing said support arms to a flat underside of a keyboard device, and
• said platform including quick release connection means for releasably securing said platform hub to a stable structure, said quick release connection means including means having cooperating members on the platform hub and the stable structure to retain the hub in a secure position on the stable structure, said quick release connection means being operable between secure and release positions of the platform by a small relative movement of the hub relative to the stable structure.
