Ladder hinge and ladder incorporating same
The invention relates to a ladder hinge and a ladder incorporating the same. The ladder includes a first pair of spaced apart members, a second pair of spaced apart members, and a first pair of hinges coupling the first pair of spaced apart members and the second pair of spaced apart members. In some embodiments, each hinge may include a first hinge component, a second hinge component, and a locking mechanism, where the first hinge component includes at least a first hinge plate having a recess formed therein, the recess including a first abutment wall and a second abutment wall, and the second hinge plate includes a second abutment wall. The second hinge component includes at least a second link plate, and the locking mechanism has a pivot pin and a locking pin. The locking mechanism is configured to selectively engage with the recess such that the pivot pin engages the first abutment wall and the locking pin engages the second abutment wall to lock the first hinge component in the first hinge position relative to the second hinge component.
本发明涉及梯子铰链和结合有梯子铰链的梯子。梯子包括第一对间隔开的构件、第二对间隔开的构件和第一对铰链，所述第一对铰链将第一对间隔开的构件与第二对间隔开的构件联接。在一些实施例中，每个铰链可以包括第一铰链部件、第二铰链部件和锁定机构，其中，所述第一铰链部件至少包括第一铰链板，所述第一铰链板具有在其中形成的凹口，所述凹口包括第一抵靠壁和第二抵靠壁，所述第二铰链部件至少包括第二链接板，所述锁定机构具有枢转销和锁定销。锁定机构被构造成与凹口选择性地接合，使得枢转销接合第一抵靠壁，并且锁定销接合第二抵靠壁以将第一铰链部件相对于第二铰链部件锁定在第一铰链位置。
