MOBILE PALM HEEL, WRIST AND FOREARM SUPPORT FOR USE WITH KEYBOARDS

摘要

An apparatus includes one or a pair of support platforms (34, 36) for supporting the palm heels, wrists and forearms of an operator relative to a keyboard (22). The support platforms (34, 36) lie in a plane keyboard keys (30). Where two support platforms (34, 36) are used, the support platforms (34, 36) are mounted on carriages (38, 40) independently of each other, so that the support platforms (34, 36) can be moved in the plane: a) in a first direction, perpendicular to the keyboard rows between forward positions where forward edges of the support platforms (34, 36) preferably overlap at least a portion of the first row (78) of keyboard keys and b) rearward positioned between the operator and the first row (78) of keyboard keys, and in a second direction, parallel to the keyboard row, whereby all keyboard keys can be operated by flexion and extension of the operator's fingers with substantially no flexion and extension of the operator's wrists which along with the operator's palm heels and forearms remain supported by and at rest on the upper surfaces of the support platforms (34, 36) during operation of the keyboard.
