Abstract
Disclosed are assemblies, systems, devices, methods, and other implementations, including an assembly that includes a moveable mechanical structure (e.g., a lever), and a gate to control movement of the moveable mechanical structure. The gate include a rotatable body, and at least two appendages extending from the rotatable body, including a first appendage configured to stop rotational movement of the gate in a first direction beyond a first angular position when the first appendage contacts a blocking structure, and a second appendage configured to contact the moveable mechanical structure that, when the moveable mechanical structure contacts the second appendage, actuates the gate to cause rotation of the gate.
Claims20
A gate to control movement of mechanical structures, the gate comprising:
- a rotatable body;
- and
- at least two appendages extending from the rotatable body, including a first appendage configured to stop rotational movement of the gate in a first direction beyond a first angular position when the first appendage contacts a blocking structure, and a second appendage configured to contact a moveable mechanical structure external to the gate that, when the moveable mechanical structure contacts the second appendage, actuates the gate to cause rotation of the gate.
An assembly comprising:
- a moveable mechanical structure;
- and
- a gate to control movement of the moveable mechanical structure, the gate comprising:
- a rotatable body;
- and
- at least two appendages extending from the rotatable body, including a first appendage configured to stop rotational movement of the gate in a first direction beyond a first angular position when the first appendage contacts a blocking structure, and a second appendage configured to contact the moveable mechanical structure that, when the moveable mechanical structure contacts the second appendage, actuates the gate to cause rotation of the gate.
An assembly comprising:
- a moveable mechanical structure;
- one or more rotatable gates to control movement of the moveable mechanical structure, each of the one or more rotatable gates comprising:
- a rotatable body, and
- an appendage extending from the rotatable body, the appendage configured to contact the moveable mechanical structure that, when the moveable mechanical structure contacts the appendage, actuates the gate to cause rotation of the gate;
- and
- one or more stationary gates, each of the one or more stationary gates including one or more of:
- a member defining a depression, the member configured to prevent movement of the moveable mechanical structure when a cross-pin extending transversely from the moveable mechanical structure is lowered into the depression, or
- a bulk protrusion extending from an elevated supporting structure, the bulk protrusion configured to prevent movement of the moveable mechanical structure when the cross-pin contacts the bulk protrusion.
