Abstract: A structure system includes a plurality of elements which mate along respective cooperating concave and convex ends. Each end has a constant common radius of curvature value and spans a predetermined included angle to provide infinitely variable articulation of mating elements within respective angular ranges. The system elements may be combined to form linear combinations as well as open and closed curves. The system is suitable for use as a work surface in classroom or office environments where the arrangement of elements may be varied readily to accommodate any number of users and floor plans.

Abstract: The present invention is a device for mounting a keyboard to a base for positioning the keyboard in a backward tilted position and for use by a hand of an operator. The keyboard has a front end, a rear end, a plurality of keys each having an uppermost surface, and an uppermost keyplane defined by the uppermost surface of the keys. In one embodiment, the device comprises first and second bracket members engagable with the base. The device further comprises a support tray comprising a support surface and a keyboard stop member. The support surface has a front portion and a rear portion and is adapted to support the keyboard. The support tray is engaged with the first and second brackets such that the keyboard may be orientated in a backward tilted position which is defined by the rear end of the keyboard being disposed below the front end of the keyboard and the uppermost keyplane being tilted backwards.

Abstract: Disclosed is a device adapted to mount to a desk for use with a computer keyboard, a mouse, or a system such as a laptop computer. In one embodiment, the device includes a stationary bracket attachable to the desk, a main housing in sliding engagement with the stationary bracket, and a keyboard support tray connected to the main housing and adapted to support the keyboard or laptop computer. The device further includes a palm rest and an optional mouse support tray. The elevation of the keyboard support tray, palm rest, and mouse support tray may be independently adjusted. The keyboard and mouse support trays may also be independently tilted to achieve a comfortable working configuration. A locking member may also be provided to secure the housing and keyboard support tray in a stored position under the desk to prevent theft or computer system operation by unauthorized persons. An anti-pry feature may also be provided for additional security.

Abstract: Disclosed is a system for positioning a computer mouse relative to a computer keyboard. The system comprises a keyboard support tray having a front portion, a rear portion, and a support surface which is adapted to support the keyboard. The system further comprises a palm rest connected to the front portion of the keyboard support tray. The system further comprises a pointing device positioning member having a support surface, a first end, and a second end. The first end of the pointing device positioning member is slidably disposed upon the wrist rest while the second end is slidably engaged with the rear portion of the keyboard support tray. In operation, the pointing device positioning member may be selectively moved about the wrist rest and the rear portion of the keyboard support tray to thereby position the computer mouse relative to the keyboard.

Abstract: Disclosed is a system for positioning a computer mouse relative to a computer keyboard. The system comprises a keyboard support tray having a support surface and a rear wall. The support surface has a front portion and a rear portion and is adapted to support the keyboard. The keyboard support tray further comprises a slot disposed in the rear wall. The system further comprises a palm rest connected to the front portion of the keyboard support tray. The system further comprises a pointing device positioning member having a support surface, a first end, and a second end. The first end of the pointing device positioning member is slidably disposed upon the palm rest while the second end is slidably engaged within the slot of the keyboard support tray. In operation, an operator may slide the pointing device positioning member to any one of a variety positions above the computer keyboard.

Abstract: Disclosed is a system for positioning a pointing device such as a computer mouse relative to a computer keyboard. The system comprises a keyboard support tray having a support surface, first and second side walls, and a rear wall. The support surface is adapted to support the keyboard. The system further comprises a palm rest connected to the keyboard support tray. The system further comprises a bracket member having a mounting portion and a channel. The mounting portion of the bracket is adapted to engage with the rear wall of the keyboard support tray. The system further comprises a pointing device positioning member having a support surface, a first end, and a second end. The first end of the pointing device positioning member is slidably disposed upon the palm rest while the second end is slidably engaged within the channel of the bracket. In operation, an operator may slide the pointing device positioning member to any one of a variety positions above the computer keyboard.

Abstract: The present invention is a device for mounting a keyboard to a base and for positioning the keyboard in a backward tilted position and for use by an operator having at least one hand. The keyboard has a plurality of keys, a front end, a rear end, and a top surface or key plane defined by a plane of the uppermost portion of the keys. In one embodiment, the device comprises a bracket engaged to the base and a clamp engaged with the bracket such that the keyboard may be orientated in a backward tilted position which is defined by the rear end of the keyboard being disposed below the front end of the keyboard. The clamp is engagable with the keyboard to prevent the keyboard from falling off when the keyboard is orientated in said backward tilted position. The clamp may comprise first and second clamp members.

Abstract: Disclosed is a device adapted to mount to a desk and for use with a computer keyboard and/or a mouse. In one embodiment, the device comprises a stationary bracket attached to the desk, a main housing attached to the stationary bracket, a keyboard support tray supportably connected to the main housing and adapted to support the keyboard. The device further comprises a palm rest movably connected to the main housing and a first engagement member being operable in a first position wherein the keyboard support tray and the palm rest are substantially movable and a second position wherein the keyboard support tray and the palm rest are substantially fixed. In a second embodiment of the present invention, the device may further comprise a mouse support tray movably connected to the main housing so that the user of the computer system may adjust the position of the mouse support tray for optimal ergonomic use of the mouse.

Abstract: A keyboard positioning system in which the keyboard is positioned with its rear edge substantially lower than its forward, or operator edge in order that the operator might use the keyboard with the plane of the operator's hands parallel to, or below the line of the operator's forearm, thus reducing the incidence of carpal tunnel syndrome. A hand support bar is provided to support the operator's hands while keyboarding.

Abstract: Disclosed is a support mechanism for mounting a keyboard to a base. In on embodiment, the support mechanism comprises a bracket member which is adapted to mount to the base and a support tray which is adapted to movably mount to the bracket member. The support tray comprises first and second side portions and a support surface adapted to receive the keyboard. The support tray is adapted such that it is movable to a position where the first side portion is disposed below the second side portion. The support mechanism further comprises a palm rest having a longitudinally disposed surface. The palm rest is movably connected to the support tray.
