Abstract
A concealed handle assembly that includes a handle base and a handle body rotatable about a first axle such that one end of the handle body can extend or return to a concealed state, the first axle being disposed on the handle base, the handle body having a handle body initial position, a handle body first open position, and a handle body second open position. The assembly further includes a rocker arm rotatable about a second axle, the second axle being disposed on the handle base, the rocker arm having a rocker arm initial position, a rocker arm first open position, and a rocker arm second open position, the rocker arm being capable of being rotated away from or returned to the rocker arm initial position as the handle body rotates, the rocker arm being capable of driving a bolt.
Claims20
A concealed handle assembly, comprising:
- a handle base;
- a first axle disposed on the handle base;
- a handle body, the handle body being rotatable about the first axle such that a first end of the handle body can extend or return to a concealed state, the handle body having a handle body initial position, a handle body first open position, and a handle body second open position;
- a rocker arm, the rocker arm being rotatable about a second axle, the second axle being disposed on the handle base, the rocker arm having a rocker arm initial position, a rocker arm first open position, and a rocker arm second open position, the rocker arm being capable of being rotated away from or returned to the rocker arm initial position as the handle body rotates, the rocker arm being capable of driving a bolt;
- and
- a slider comprising a rotating block and a slider holder, the rotating block being disposed on the slider holder, the rotating block comprising a bevel, and the slider being configured to push the handle body such that the handle body rotates from the handle body initial position to the handle body first open position,
- wherein rotation of the handle body from the handle body first open position to the handle body initial position is initiated by an external force,
- wherein, the external force causes the handle body to rotate the rotating block,
- wherein, when the rocker arm is rotated by a first predetermined angle in a first direction from the rocker arm initial position, the handle body reaches the handle body first open position, and
- wherein, when the rocker arm continues to rotate by a second predetermined angle in the first direction from the first predetermined angle, the handle body reaches the handle body second open position, wherein when the handle body is in the handle body second open position, the rocker arm can drive the bolt to unlock.

- a handle body, the handle body being rotatable about a first axle such that one end of the handle body can extend or return to a concealed state, the first axle being disposed on the handle base, the handle body having a handle body initial position, a handle body first open position, and a handle body second open position;
- a rocker arm, the rocker arm being rotatable about a second axle, the second axle being disposed on the handle base, the rocker arm having a rocker arm initial position, a rocker arm first open position, and a rocker arm second open position, the rocker arm being capable of being rotated away from or returned to the rocker arm initial position as the handle body rotates, the rocker arm being capable of driving a bolt;
- a driving device, the driving device being capable of driving the handle body to rotate about the first axle, thereby driving the rocker arm to rotate;
- a first energizing device, the first energizing device being configured to, when the rocker arm is rotated from the rocker arm initial position to the rocker arm first open position, generate a stop signal, thereby stopping the driving device;
- and
- a slider comprising a rotating block and a slider holder, the rotating block being disposed on the slider holder, the rotating block comprising a bevel, the slider being driven by the driving device and the slider being configured to push the handle body such that the handle body rotates from the handle body initial position to the handle body first open position,
- wherein, when the rocker arm is rotated by a first predetermined angle in a first direction from the rocker arm initial position, the handle body reaches the handle body first open position,
- wherein, when the rocker arm continues to rotate by a second predetermined angle in the first direction from the first predetermined angle, the handle body reaches the handle body second open position, in the handle body second open position the rocker arm can drive the bolt to unlock,
- wherein the bevel is in contact with the handle body such that the handle body is rotatable about the first axle when the slider is linearly moved,
- wherein the rotating block is linearly movable with the slider holder, enabling the handle body to rotate about the first axle along the bevel, and
- when it is desired to return the handle body from the handle body first open position to the handle body initial position, an external force can be applied to the handle body to cause the handle body to rotate the rotating block, thereby starting the driving device, so that the handle body returns from the handle body first open position to the handle body initial position.
