Abstract
A cuckoo clock having a scissored extension arm is disclosed. The clock, using the arm, provides an attractive visual display with minimum displacement and shift of center of gravity.
Claims27
A cuckoo clock having a scissored extension for displaying an ornamental object, comprising:
- a three-dimensional housing, having a clock face;
- a timing module connected to the housing, responsible for initiating a cuckoo display event at a predetermined time, controlling how long the cuckoo stays outside of the clock, and triggering the correct amount of cuckoo sounds;
- a scissor armature, connected to the housing and the timing module;
- a scissoring extension connected to the scissor armature, for displaying an ornamental object which travels back and forth solely in a linear path, wherein that path is determined by twin sliding guides which are located on either side of the scissoring extension and are fixedly secured within the interior of the clock;
- and
- a transverse roller bar having roller mechanisms at each end movably secured within the guides, and connected to both the scissoring extension and the scissor armature;
- wherein the scissoring extension is also connected to the transverse roller bar.
4 more elements
A method of operating a cuckoo clock, comprising:
- signaling that a cuckoo display event is impending;
- pivoting an actuator in a predetermined direction;
- pulling down a cantilever which is physically joined to an activation mechanism;
- pushing down on a brake;
- releasing a flywheel;
- thereby
- allowing snail gears to begin rotating;
- providing a scissor armature connected to a scissoring extension and a transverse roller bar;
- as the snail gears complete their rotation, pushing out the scissor armature;
- thereby
- locking a fork into a star gear;
- thereby
- holding both the scissoring extension and scissor armature in a fully extended position;
- rotating the snail gears until they come to locking pins located on the bottom portion of the scissor armature;
- while simultaneously
- operating a cuckoo sound mechanism for a predetermined amount of cycles;
- releasing a fork when the desired number of cuckoos is achieved;
- signaling that a cuckoo display event is completed;
- releasing the fork;
- thereby
- allowing the scissor armature to unlock and be subject to the pull of springs;
- thereby
- relocating the transverse roller bar into its rearward position.
