Abstract

This disclosure pertains to a terminal key, specifically to a "space bar" which can rotate along its long axis in order to provide an additional function. The traditional use of the space bar is maintained. However, an additional function is available by rolling the bar. For example, roll forward or back to scroll; push down on the bar for standard use. The rolling bar can be locked into any desired position.

Space Bar That Rolls

This disclosure pertains to a terminal key, specifically to a "space bar" which can rotate along its long axis in order to provide an additional function. The traditional use of the space bar is maintained. However, an additional function is available by rolling the bar. For example, roll forward or back to scroll; push down on the bar for standard use. The rolling bar can be locked into any desired position.

Notice that the roller can provide a continuous (analog) function, or it can be in the form of a multifaceted cylinder (e.g., a hexagon) such that detent settings are provided. This discontinuous movement can provide different functions, such as different spacings. The faces of the roller can conveniently display functions or numbers to indicate the purpose for the settings. The space bar is large and easy to manipulate with either of the user's hands. Note that, in an alternate embodiment, a small roller can be embedded into a standard space bar.

Fig. 1 shows a typical keyboard 1 that has a rotating roller incorporated into the space bar 2. A cavity is molded into the space bar frame. The roller is seated within the cavity and held in place at both ends by cutouts in the cavity.

Fig. 2 shows the details of one possible embodiment of the space bar. A cavity 3 is molded into the space bar frame 4. The roller is seated within the cavity. Each bushing tab 5 at both ends of the roller are held in place by cutouts in the cavity.
