Pivoting latch locking assemblies for height-adjustable twistlocks

A twistlock assembly that is adjustable over a range of heights of a load level of the twistlock assembly relative to a deck level of the twistlock assembly, comprising:

• a housing base;
• a locking pin rigidly connected with a shaft, the locking pin having an adjustable vertical position relative to the housing base of the twistlock assembly that corresponds to a vertical position of the load level of the twistlock assembly relative to the deck level of the twistlock assembly;
• and
• a locking latch assembly comprising:
• a mounting bracket configured to be secured to the housing base of the twistlock assembly;
• a latch having a forked portion configured to engage with the shaft;
• an axle passing through the mounting bracket, the latch being secured around the axle to allow the latch to pivot relative to the mounting bracket;
• and
• a latch pin secured on the mounting bracket, the latch pin engaging a first surface of the latch when the latch is in a locked position in which the latch is at a first angular position relative to the mounting bracket and the forked portion of the latch engages with the shaft, and engaging a second surface of the latch when the latch is in an unlocked position in which the latch is at a second angular position relative to the mounting bracket and the forked portion of the latch is disengaged from the shaft, wherein the latch pin is configured to be disengaged from the latch to allow the latch to pivot relative to the mounting bracket between the locked position and the unlocked position;
• the forked portion of the latch being configured to engage with the shaft, in the locked position of the latch, so that the shaft is substantially restricted from rotational movement while the latch is in the locked position, throughout all of the range of heights of the twistlock assembly.

A twistlock assembly that is adjustable over a range of heights of a load level of the twistlock assembly relative to a deck level of the twistlock assembly, comprising:

• a T-shaped twistlock locking pin having a head and a stem;
• a housing base, the stem of the T-shaped twistlock locking pin passing through the housing base, the T-shaped twistlock locking pin having an adjustable vertical position relative to the housing base of the twistlock assembly that corresponds to a vertical position of the load level of the twistlock assembly relative to the deck level of the twistlock assembly;
• and
• a shaft secured to the stem of the T-shaped locking pin;
• the stem of the T-shaped twistlock locking pin having an upper bolt hole and a lower bolt hole passing therethrough, the upper bolt hole passing through the stem in a direction perpendicular to the lower bolt hole;
• the shaft having an upper bolt hole and a lower bolt hole passing therethrough, the upper bolt hole passing through the stem in a same direction as the lower bolt hole;
• the shaft being adjustably secured to the stem of the T-shaped twistlock locking pin by a bolt passing through the upper bolt holes of the shaft and the stem or passing through the lower bolt holes of the shaft and the stem.
