Abstract
The multi-purpose Combo Jack.TM. tool combines the functions of a ladder jack, a roof bracket and a roof hooks into one piece of equipment. There are a pair of hooks attached to a rail supporting arm which is pivotably connected to a bracket body arm. The bracket body arm includes the plank stop lever and a retractable nailing blade. A combination support arm is connected to the rail support arm at either the tri-function setting or the steep roof bracket setting, and is also connected to the upward or downward slots in the bracket body arm (or at the end but not in a slot). The tool includes a safety stop as part of the retractable nailing blade, a ladder lock, and a safety protrusion to prevent collapse of the tool because of slippage along the bracket body arm by the combination support arm.
Claims40
A multi-purpose roof and ladder device comprising:
- a first member having first and second engaging regions, said first engaging region including at least first and second engagement settings;
- a second member having a longitudinal axis and first and second engaging regions, said first engaging region pivotally connected to said second engaging region of said first member, said second engaging region of said second member including a first set of at least one engaging slot disposed at an acute angle relative to said longitudinal axis, and a second set of at least one engaging slot disposed at an obtuse angle relative to said longitudinal axis;
- and
- a third member having first and second engaging regions, said first engaging region having an engaging mechanism for engaging one of said at least first and second engagement settings of said first engaging region of said first member, said second engaging region having an engaging mechanism for selectively engaging one engaging slot from said first and second sets of at least one engaging slot of said second engaging region of said second member.
A multi-purpose roof and ladder device comprising:
- a first member, a second member and a third member;
- a first end of said first member coupled to said second member;
- said first member coupled to said third member;
- said third member adjustably coupled to said second member;
- a movable roof attachment member movably attached to said second member for connection to a roof;
- and
- a coupling member disposed on said first member for connection to a weight supporting member.
A ladder securing device comprising:
- a first member, a second member and a third member;
- said first member coupled to said second member;
- said second member coupled to said third member;
- said third member coupled to said first member;
- said first member coupled to a ladder hook;
- said ladder hook having an opening;
- a movable locking member adjacent said ladder hook;
- and
- said movable locking member having a resilient component for maintaining said locking member in a first position substantially blocking said opening of said ladder hook for locking an object within said ladder hook and for allowing compressive displacement of said locking member to a second position wherein said locking member is substantially absent from said opening of said ladder hook for releasing said object.
