Finger activated switching device

Abstract

A finger activated switching device has an enclosure with a top wall and a bottom wall, the bottom wall movable on a supporting wall. An upper lever is pivotally joined to the enclosure, and is upwardly spaced apart from the top wall in a first rest position yet is upwardly displaceable using finger pressure from below. A lower lever is pivotally joined to the enclosure directly below the upper lever, and spaced apart from it in a second rest position yet is downwardly displaceable using finger pressure. When the levers are displaced from their rest positions a restoring element moves the levers back to their rest positions. Switching elements positioned in force transmission mechanisms with the levers provide electrical switching actions when the levers are displaced.

DETAILED DESCRIPTION

(5) Embodiments illustrated in FIGS. 1-6 depict a finger activated switching device otherwise well known generically as a computer mouse and in this disclosure we use the term mouse 10 to represent this described and illustrated switching device. It should be recognized that this finger activated switching device, mouse 10, may be adapted for use in other applications where finger movement activation of one or more electrical switching functions, for instance using switch 60 or switch 62 is desired or required. However, when used as a computer pointing device the presently described mouse 10 is intended to be used on a table top, mouse pad, or other supporting surface 20 for electronically moving a computer display screen pointer wherein such enablement is not shown or described herein, for instance, to a desired position on a computer screen (not shown), or for moving a graphical or text item to a desired position on said screen, for identifying a portion of text, and many other functions in visual screen operations well known in the art.

(6) In an embodiment, as shown in FIGS. 1 and 2, mouse 10 may comprise a enclosure 30 which may be of molded plastic, for instance, and which may have a top wall 32 and a bottom wall 34 wherein said bottom wall 34 is intended to be rested on and be moved over said supporting surface 20 as is well known in the use of computer mice for computer visual screen operations. Enclosure 30 may have opposing side walls 36 so that walls 32, 34, and 36 form a mostly closed enclosure 30 which may be held in one hand as is typical of computer mice.

(7) As also shown in FIGS. 1 and 2, an upper lever 40 may be supported by enclosure 30 by a first hinge 42 held by opposing standoffs 44, which standoffs may be attached at top wall 32 and extend upwardly therefrom, as shown. Upper lever 40 may be positioned above and apart from said top wall 32 in a first rest position 40R while alternatively being upwardly displaceable from rest position 40R by finger pressure below upper lever 40 in an upward motion shown by arrow A to thereby position one end of upper lever 40 in position 40D while the opposing end of upper lever 40 rotates downward as shown by arrow B and depresses a first switch 60 supported on block 60B. As clearly shown, upon the execution of this motion upper lever 40 rotates about first hinge 42. FIG. 5 shows an example of first switch 60 in its non-actuated state whereby electrical contacts 64 are open. FIG. 6 shows the same switch 60 with the electrical contacts 64 closed as force F is applied by finger pressure to upper lever 40. When finger pressure is removed, electrical contacts 64 open once more as spring 66 press upward to their non-compressed state and upper lever 40 resumes its rest position.

(8) As further shown in FIG. 2, a lower lever 50 may be joined to enclosure 30 by a second hinge 52 held at its opposing ends directly by enclosure 30 at top wall 32. Lower lever 50 is normally positioned in a second rest position 50R while alternatively being downwardly displaceable from rest position 50R by finger pressure from above onto lower lever 50 in a downward motion shown by arrow C to thereby place one end of lower lever 50 in position 50D which therefore presses on second switch 62 which may be supported on block 62B which is clearly supported by bottom wall 34. As clearly shown, upon the execution of this motion lower lever 50 rotates about second hinge 42 actuating switch 62 and when finger pressure is removed from lower lever 50, spring 66 of switch 62 moves lower lever 50 back to said second rest position 50R.

(9) In an embodiment, when finger pressure is released from levers 40 or 50 after a displacement motion, levers 40 or 50 immediately move back to their respective rest positions 40R or 50R as urged by a restoring element 45 which may be a spring or the like. For instance FIG. 5 shows that switches 60 and 62 may have a spring 66 wherein, once depressed and released, moves the levers 40 or 50 back to their rest positions 40R and 50R and allows switches 64 to open. Switches 64 may have a means for moving to the non-actuated state such as a spring loading or otherwise as would be known by those of skill in the electrical arts, or connector bar 68 may be attached to switch 64 so as to pull switch 64 into an open state.

(10) In an embodiment FIG. 3 shows that blocks 60B and 62B may be replaced by extension rods 40E and 50E which may be pinned and pivoted from their respective levers 40 and 50, or may be structural extensions thereof.

(11) In an embodiment FIG. 4 shows that instead of blocks 60B and 62B or extension rods 40E of the embodiments shown in FIGS. 2 and 3, a pivotable platform 77 may be mounted on a spring 72 so that it may tilt to the left to actuate switch 60 when lever 40 is displaced, or tilt to the right to actuate switch 62 when lever 50 is displaced. Upon release of finger pressure on levers 40 and 50, spring 72 moves platform 77 back to the neutral position shown in FIG. 4 wherein platform 77 presses down on neither switch 60 nor 62.

(12) The embodiments of FIGS. 2-6 are mechanical manifestations of the present apparatus which follow the same fundamental arrangement to accomplish the same result and are therefore physically and functionally enabled under the same inventive concept, but other manifestations or embodiments may be used in a similar manner to accomplish the same result. It should be understood, and is obvious that other mechanical arrangements identical or similar to the elements described above may be arranged so that displacement of either lever 40 or lever 50 would be able to actuate the same switch, that is when using only one switch 60 or 62 instead of two switches, and it is within the skill of those practicing the mechanical arts under the above description to activate one switch with either or both of levers 40 and 50.

(13) It should be understood that said finger activated switching device (mouse 10) may have two or more sets of levers 40, 50 enabled, as described above, for switching multiple sets of switching elements 60 and 62. FIG. 1 illustrates an embodiment of mouse 10 having two sets of levers 40, 50 located in side-by-side positions, however, a plurality of more than two sets of levers 40, 50 with the same mechanical arrangements for actuating more than two sets of switches 60, 62 will be understood by those of skill.

(14) Embodiments of the subject apparatus and method of use have been described herein. Nevertheless, it will be understood that modifications by those of skill in the art may be made without departing from the spirit and understanding of this disclosure. Accordingly, other embodiments and approaches are within the scope of the following claims.
