    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to FIGS. 2, 3, and [0017] 4, a notebook computer key of the present invention is illustrated. The key 10 includes a key hat 11, an elastic touch moving piece 12, a first supporting frame 13, a second supporting frame 13 and a base 1. The key hat 11 is a rectangular key hat. The top and bottom thereof are formed with an operating surface 16 and an assembling surface 17. The assembling surface 17 is installed with two pivotal shafts 18 and two sliding grooves 19.
  • The first supporting [0018] frame 13 and the second supporting frame 14 are arranged between the assembling surface 17 and the seat 15. Pivotal shafts 20 and pivotal holes 21 are installed on the middle portions of the two sides of the first supporting frame 13 and second supporting frame 14. Thus, the first supporting frame 13 and second supporting frame 14 are pivotally connected as interleaved linkage means.
  • The elastic [0019] touch moving piece 15 is installed between the key hat 11 and the base 15. The elastic touch moving piece 15 is in the traveling length of the key hat 11. The two sides of the first supporting frame 13 are installed with respective pivotal shafts 22 at the upper ends thereof. Each of the two sides of the second supporting frame 14 is installed with a sliding shaft 23. The supporting frames 13 and 14 are pivotally and slidably connected to the pivotal hole 18 and the sliding groove 19 by the pivotal shafts 22 and sliding shafts 23 at the upper ends of two sides thereof, thus the first supporting frame 13 and the second supporting frame 14 are connected to the assembling surface 17 of the key hat 11 at the upper ends thereof.
  • The lower ends at two sides of the first supporting [0020] frame 13 and the second supporting frame 14 are installed with respective pivotal shafts 24 and 25 pivotally connected to the through holes 26 and 27 preset on the seat 15. The upper sides of the through holes 26 and 27 are installed with respective positioning pieces 28 and 29 for confining the upward displacement of the pivotal shafts 24 and 25. A soft circuit board 33 is installed on the seat 15. The key hat 11 is guided by two supporting frames 13 and 14 so as to move upwards and downwards. The elastic touch moving piece 12 on lower side of the key hat 11 may touch-press or separate with the soft circuit board 33 so that the switch may be turned on or off.
  • In the present invention, primarily, the [0021] pivotal shafts 24 at lower ends of the two sides of the first supporting frame 13 are improved. The pivotal shaft 24 is protruded from a lateral wall 30 (outer lateral wall) and a second lateral wall 31 (front lateral wall or rear lateral wall) (as FIG. 5A and FIG. 5E) of the first supporting frame 13. When pivotal shafts 24 at lower ends of two sides of the first supporting frame 13 are pivotally connected to the through holes 26 of the seat 15, most of each pivotal shaft 24 is inserted into the through hole 26. The second supporting frame 14 (or the second supporting frame 13) has end portion 34 at lower end thereof. The end portion 34 is protruded with at least one convex body 37 and respective stopper 38 are protruded from the seat 15. The pivotal shafts 25 at lower ends of two sides of the second supporting frame 14 have a structure identical to the pivotal shafts 24 at lower ends of the two sides of the first supporting frame 13. Namely, the pivotal shaft 25 is protruded from the first lateral wall (outer lateral wall) 35 and the second lateral wall (front lateral wall or rear lateral wall) 36 of the second supporting frame 14, thus, the pivotal shaft 25 may inserted into the through hole 27. Since the pivotal shafts 24 and 25 at lower ends of the two sides of the first supporting frame 13 and second supporting frame 14 may be inserted into the through holes 26 and 27. Therefore, the height of the key is reduced greatly so that the requirement of compactness of modern product is matched.
  • The [0022] pivotal shafts 24 and 25 at lower ends of the two sides of the first supporting frame 13 and second supporting frame 14 provide a stopping effect for upward movement through the positioning pieces 28 and 29. While, the end portions 32 and 34 at lower ends of the two sides of the first supporting frame 13 and second supporting frame 14 provide a stopping effect through the seat 15 so as to prevent the downward movement of the pivotal shafts 24 and 25 at lower ends of the supporting frames 13 and 14. As a result, the supporting frames 13 and 14 may have a preferred positioning effect in the Z axis (upper and lower directions). The first lateral walls 30 and 35 of the two lateral walls 13 and 14 may prevent a stopping effect to the leftward and rearward displacement by the positioning pieces 28 and 29. Further, the pivotal shafts 24 and 25 at lower ends of the supporting frames 13 and 14 provides a stopping effect to the leftward and rightward movements of the lateral walls through the through holes 26 and 27. Thus, he supporting frames 13 and 14 is well positioned in the X directions (left and right). Moreover, the pivotal shafts 24 and 25 provides a stopping effect to the forward and rearward movement by the positioning pieces 28 and 29. Further, the stopping edge 38 of the seat 15 provides a stopping effect to the forward and rearward movement of the protrusion 37 at lower end of the second supporting frame 14 (or first supporting frame 14). Thus, the second supporting frame 13 and 14 are well positioned in the Y axis (front, rear). Thus, the two supporting frames 13 and 14 are well positioned in three axial directions. The two supporting frames 13 and 14 can be steadily and pivotally connected to the seat 15.
  • Although the present invention has been described using specified embodiment, the examples are meant to be illustrative and not restrictive. It is clear that many other variations would be possible without departing from the basic approach, demonstrated in the present invention. [0023]
