Keyboards with elevated keys
First Claim
1. A key structure, comprising:
- a main body;
a key cap;
a substrate;
a first rod, comprising a first end movable in a first direction and a second end connected to the key cap;
a second rod connected to the first rod, comprising a third end and a fourth end, wherein the third end connects the substrate and the fourth end movably connects the key cap; and
a slider movable in the first direction with respect to the substrate between a first position and a second position, wherein when the slider is in the first position, the key structure is in an original state and the key cap is situated at a first height with respect to the substrate; and
a resilient member, connecting the slider and the first rod, wherein the resilient member is extended and provides a pre-tension force to the first rod when the key structure is situated in the original state, and when the slider moves from the first position to the second position, the first rod is impelled by the slider, and the key cap descends toward the substrate to a second height lower than the first height such that the key structure is situated in a depressed state.

Abstract
Keyboards with elevated key structures are provided. An exemplary embodiment of a key structure includes a key cap, a substrate, a slider, a resilient member, a first rod and second rod. The slider is movable in a first direction with respect to the substrate between a first position and a second position. The first rod connects the substrate and the key cap. The second rod connects the key cap, the substrate and the first rod. The resilient member connects the slider and the first rod. When the key structure is in an original state with the slider situated in a first position, the key cap is situated at a first height. When the slider moves from the first position to the second position, the first rod is impelled by the slider, and the key cap descends toward the substrate to a second height less than first height.

15. A keyboard, comprising:
-
a substrate; a plurality of key structures, each of the key structures comprising; a key cap; a slider movable in a first direction with respect to the substrate between a first position and a second position; a first rod, comprising a first end movable in the first direction and a second end connected to the key cap; and a second rod connected to the first rod, comprising a third end and a fourth end, wherein the third end connects the substrate and the fourth end movably connects the key cap; and a resilient member, connecting the slider and the first rod, wherein the key structure is in an original state and the key cap is situated at a first height with respect to the substrate when the slider is in a first position, and when the slider moves from the first position to the second position, the first rod is impelled by the slider and the key cap descends toward the substrate to a second height lower than the first height, such that the key structure is in a depressed state, wherein when the key cap is pressed toward the substrate from the original state, the resilient member is extended and exerts a recovery force for returning the key structure to the original state. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A resilient mechanism, exerting a recovery force on a key cap, comprising:
-
a substrate; a first rod, comprising a first end movably connected to the substrate and a second end connected to the key cap; a second rod connected to the substrate and the key cap, wherein the first and second rods are pivotally connected to form a scissors-type support mechanism; a slider movable in a first direction with respect to the substrate between a first position and a second position; and a resilient member connecting the slider and the first rod, wherein the first and second rods form a first angle and the slider is in the first position when the resilient mechanism is situated in an original state, and when the slider moves from the first position to the second position, the first rod is impelled by the slider in the first direction, and the first and second rods form a second angle exceeding the first angle, such that the key structure is in a depressed state, wherein when the key cap is pressed toward the substrate from the original state, the resilient member is extended and exerts the recovery force on the key cap. - View Dependent Claims (30, 31, 32)
