Patent Images
1. An extendible and contractable keyboard, comprising:
- a housing which is extensible and compressible in at least one dimension;
frame means which attach to and extend and compress with said housing;
a plurality of keyboard switching means attached to and positionally dependent upon the extension and compression of said frame means whrein the keyboard switching means intercomponent spacing varies as the frame means extends and compresses;
means for electrically interconnecting said keyboard switching means to a keyboard electronic control and timing circuit means;
said interconnecting means being capable of retaining a predetermined juxtaposed position at each connection to said keyboard switching means as the frame means extends and compresses.

Abstract
An extensible and compressible keyboard for application in computer, calculator, typewriter, and other similar applications where storage space is a premium. The keyboard provides adjustable spacing between the keys whereby a compact storage unit is expanded to a full-size, full function, and normally spaced standard keyboard or, as importantly, to a size which best fits the fingers of an individual user.

18. An extendible and contractable keyboard comprising:
-
a housing which is extendible and compressible in two dimensions while remaining substantially unchanged in a third dimension; frame means which attach to and extend and compress with said housing; a plurality of keyboard switching means attached to and positionally dependent upon the extension and compression of said frame means wherein the keyboard switching means intercomponent spacing varies as the frame means extends and compresses; means for electrically interconnecting said keyboard switching means and electronic control and timing circuit means said interconnecting means pliably unfolding and gathering whereby a predetermined juxtaposed position at each connection to said keyboard switching means is retained as the frame means extends and compresses.

19. A method for adjusting the spacing of an extendible and contractible keyboard to match the desired finger travel of a user, comprising the following steps:
-
a. providing an extendible and contractable keyboard housing comprising the extendible and contractible keyboard; b. extending or compressing the housing of the keyboard laterally until inter-column keypad distances match a desired inter-column keypad distance; c. extending or compressing the housing of the keyboard in a direction normal to the direction of extending or compressing of step b until the inter-row keypad distances match a desired row-to-row distance. - View Dependent Claims (20)

21. An extendible and contractible frame for a keyboard comprising:
-
a plurality of keyboard switching means attached to and positionally dependent upon the extension and compression of said frame and means providing for extension and contraction of the space between each pair of adjacent keyboard switching means responsive to extension and contraction of the keyboard; means for electrically interconnecting said keyboard switching means to a electronic control and timing circuit means said interconnecting means pliably unfolding and gathering whereby a predetermined juxtaposed position at each connection to said keyboard switching means is retained as the frame extends and compresses.

23. An extendible and contractible keyboard for varying the spacing between the keys without requiring individual adjustment of the keys, said keyboard comprising:
-
a plurality of keyboard switching means and means providing for extension and contraction of the space between each pair of adjacent keys responsive to extension and contraction of the keyboard; electrical interconnection means which retain electrical connection between the keyboard switching means as the spacing of keys varies.
