  • Patent number: 9831049
    Abstract: A key structure includes a carrying body, a frame body, a keycap and at least two independent connecting members. The frame body is disposed on the carrying body and forms plurality of sliding grooves. The keycap has a plurality of cap edges and is disposed with a plurality of pivoting portions. The at least two connecting members are each connected between the keycap and the frame body, corresponding to two of the cap edges opposite to each other. Each connecting member includes a pivoting rod and a sliding rod. Each pivoting rod pivots on one of the pivoting portions, and each sliding rod is slidably limited in one of the sliding grooves. This design has preferred structural strength, smooth pressing movement and reliable pressing contact.

  • Patent number: 9773623
    Abstract: A keyswitch structure includes a base plate, a key cap, a key base, a recovering member and a linkage mechanism having linkage members. The key base is disposed between the key cap and the base plate. The recovering member is disposed between the key cap and the base plate. The linkage members are physically separated from each other, and are respectively inclinedly disposed between the key base and the key cap, and collectively surround the recovering member. One end of each of the linkage members is pivotally connected to the key base, and the other end of each of the linkage members is slidably connected to the key cap.

  • Patent number: 9734962
    Abstract: A key structure includes a carrying body, a frame body, a keycap and at least two connecting members. The frame body is disposed on the carrying body, and the frame body is disposed with a plurality of sliding grooves. The keycap has a plurality of cap edges and correspondingly covers the top of the frame body, and the keycap is disposed with a plurality of pivoting portions. The at least two connecting members are independent from each other. The at least two connecting members are connected between the keycap and the frame body, corresponding to the two cap edges opposite to each other. Each connecting member includes a pivoting rod and a sliding rod. Each pivoting rod pivots on each pivoting portion. Each sliding rod is slidably limited in each sliding groove, and the pivoting portions are correspondingly located on the outside of the sliding grooves.

  • KEY
    Publication number: 20150340175
    Abstract: A key is provided. The key includes a substrate, a keycap member, a first balance rod and a second balance rod. The keycap member is movably disposed on the substrate and includes two short lateral sides and two long lateral sides. The first balance rod is disposed between the keycap member and the substrate. An extended direction of the first balance rod is parallel to profile lines of the long lateral sides, and the first balance rod is connected to one of the two long lateral sides and the substrate. The second balance rod is disposed between the keycap member and the substrate. An extended direction of the second balance rod is parallel to profile lines of the short lateral sides, and the second balance rod is connected to the short lateral sides and the substrate.
