  • Patent number: 11499344
    Abstract: The disclosure relates to a magnetic-actuation latch device. The magnetic-actuation latch device includes a housing, a latch element, a sliding plate, an elastic component, a rotating element and a limitation element. A lateral opening of the housing spatially corresponds a first magnetic block mounted on a fixed component. When a second magnetic block of the latch element is aligned to the first magnetic block, an actuation force is generated to drive the latch element to pass through the lateral opening and engage with the fixed component. The elastic component is connected between the sliding plate and the housing. When the rotating element is rotated by an external force, the sliding plate is driven to misalign the second magnetic block from the first magnetic block, and the latch element does not pass through the lateral opening. The limitation element is pivotally connected to the housing for blocking the rotating element.

  • Patent number: 11168496
    Abstract: The present invention provides a latching device and a sliding door using the same. The latching device includes two displacement components and two latching components arranged on the main body of the sliding door. The two displacement components are connected to each other and respectively arranged to drive the two latching components to displace. The two displacement components are operated through the lateral side and the edge side of the sliding door, respectively. The user can latch or unlatch the sliding door by operations of displacing the at least two displacement components when the sliding door is in a closed state or a completely open state. In addition, when a concealed sliding door is fully opened and the two sides are both hidden in the walls, the sliding door can be latched or unlatched by operating the latching device through the edge side of the sliding door.

  • Patent number: 10550613
    Abstract: A pressing type latch device includes a seat, a pivotal seat mounted in the seat, and a handle having a grasping portion pivotably connected to two eccentric locations of the pivotal seat, such that a greater operational height can be formed when the handle is lifted. When the latch device is in one of a plurality of retainable open positions or a retainable closed position, the grasping portion of the handle can be moved to a position to lift the pivotal seat, such that the grasping portion of the handle lies flush with the pivotal seat. On the other hand, when the grasping portion of the handle is lifted to move the pivotal seat downward, the handle and the pivotal seat can rotate freely. Since the latch device includes a closed position and a plurality of open positions, the latch device can be installed and used more easily.

  • Patent number: 10492323
    Abstract: The present invention provides a three-dimensional angular adjusting and positioning device, which comprises a fixing member, a first adjusting member and a second adjusting member. The relative positions of the second adjusting member, the first adjusting member and the fixing member are adjusted by switching an arm with an eccentric cam of the second adjusting member to drive two engaging portions between the fixing member and the first adjusting member and two engaging portions between the first adjusting member and the second adjusting member. While the engaging portions are separated from each other, an adjustable state is achieved. While the engaging portions are engaged with each other, a positioned state is achieved. Thus, the electronic equipment mounted on three-dimensional angular adjusting and positioning device can be adjusted to a specific angle and then positioning according to the practical requirements. It avoids the displacement due to the collision or gravity.
