Abstract
Disclosed herein is a multiple line writing instrument which is adapted for one-handed operation in the general manner of an ordinary pen or pencil and which accomodates variations in the writing angle at which the instrument may be applied to a writing surface. The instrument includes plural elongate writing means, such as pens, held in parallel, spaced apart array. By means of a pivotal stop table the writing tips of the plural writing means are held in continous writing contact with a writing surface despite variations in writing angle which may occur during use. The multiple line writing instrument avoids the necessity to employ biasing elements, such as springs, to maintain writing contact of the writing tips with the writing surface.
Claims14
A multiple line writing instrument of a size and shape for one-handed use thereof, said instrument comprising:
- an enclosure having secured therein holder means comprising multiple apertures, each said aperture receiving in sliding relationship therethrough an elongate writing means having a writing tip whereby said multiple elongate writing means are established in a spaced apart parallel array oriented longitudinally of said enclosure, the writing tips of said array extending to the exterior of said enclosure and whereby each said elongate writing means is enabled to stroke upwardly and downwardly of said holder means;
- a journalled stop table secured to said enclosure and having a least one slot therethrough to slidingly receive each said elongate writing means of said array, said stop table being journalled so as to pivot transversely with respect to the longitudinal axis of said enclosure and responsively to upwardly directed forced imposed thereupon by at least certain of said elongate writing means when the instrument is held at a writing angle with respect to a writing surface and the plural writing tips of the elongate writing means array are contacted with said writing surface, and (b) to pivot sufficiently in accordance with (a) as to establish and maintain a parallel relationship to said writing surface;
- and up stop means affixed to each elongate writing means of said array at a distance from the writing tip thereof, said up stop means butting against the bottom of said stop table upon upward stroking of the writing means associated therewith, thereby to define the upward stroke limit of said associated writing means, said distance of each said up stop means from said writing tip of said elongate writing means of said array being such as to maintain the writing tips of the entire array of elongate writing means in writing contact with said writing surface.
