Hand-held programmable sign with rotatable handle
First Claim
1. A portable programmable sign, comprising, in combination,a hand-grip housing having front and rear hand-grip housing sides, a sign housing having front and rear sign housing sides, miniaturized microprocessor means for processing data mounted within the sign, keyboard means mounted in said hand-grip housing for receiving input data and transmitting the input data to said microprocessor means, said keyboard means including a keyboard miniaturized microprocessor, message display means for presenting the input data to an observer, said message display means including a message display mounted on said front sign housing side, said hand-grip housing being rotatably mounted with said sign housing wherein said hand-grip housing is rotatable between an in-use position wherein said hand-grip housing is transverse to said sign housing and a compact position wherein said hand-grip housing is positioned in overlapping relationship with said sign housing, rotatable mechanism means for connecting said sign housing and said hand-grip housing for movement between said in-use position and said compact position, said rotatable mechanism means being connected to said first and second housings, locking means associated with said rotatable mechanism means for locking said first and second housings in one of a selected said in-use position and said compact position, circuit means for electrically joining said keyboard means, said microprocessor means and said message display means, power means for supplying electrical current to said circuit means, and on/off means for connecting and disconnecting said circuit means with and from said power means.

Abstract
A hand-held programmable sign comprising a hand-grip portion and a sign portion having opposed front and rear sides and including an upper sign portion and a lower hand-held portion rotatably mounted to the sign portion midway transverse to the sign portion in the in-use mode. The hand-grip portion can be rotated between the in-use mode and a locked storage mode when the hand-grip portion is rotated into overlapping relationship with the sign portion. A keyboard system with a miniaturized keyboard processor including keys marked with indicia for letters of the alphabet, numerals, and other selected indicia is mounted on the hand grip portion for operator input. The sign includes a miniaturized computer microprocessor for processing input data received from the keyboard. A miniaturized light-emitting message display, preferably an LED display, is mounted on the front side of the sign portion for reading by an observer. An electrical circuit in both the sign housing and the hand-grip housing joins the keyboard system, computer microprocessor, the light-emitting message display and an optional miniaturized monitor display system mounted on the rear side of the sign portion are joined by an electrical circuit in the housing and which can be internally or externally powered.
