Abstract
Disclosed are aspects of exemplars of torque-limiting devices, methods and mechanisms. Exemplary methods may include placing an actuator in a tool containment interface of a handle, the interface being fluidly connected to an adjustment interface and adjustable via a fixation fastener; movably mounting a tool portion with an actuation catch and a work piece engaging region (WER) in the interface; applying sufficient force to the movable mounting to the handle may be via pins, guides and slots. Said catch may be one of a body catch and a lever catch; and, the actuator terminates on one of a ball shaped end that forms an interface with the body catch and a force lever that forms an interface with the lever catch.
Claims10
An adjustable disposable torque limiting device comprising:
- a handle with a tool containment interface;
- a first pin guide and a third pin guide formed through said handle;
- said tool containment configured with a closed end formed in said handle;
- an actuator with a movable ball end mounted in said containment;
- an adjustment interface connected to said containment;
- a tool portion configured to movably fit in at least part of said tool containment comprising:
- a work piece engaging region;
- a retention slot formed in said tool portion;
- a guide slot formed in said tool portion;
- and
- a body catch forming an interface for said movable ball end of said actuator;
- a first pin configured to fit through said first pin guide and move along in said retention slot in said tool portion during rotational movement of said tool portion;
- a second pin configured to fit through said third guide and move along said guide slot in said tool portion during rotational movement of said tool portion;
- wherein said tool portion may be removed from said tool containment by rotating it off of said first and second pins;
- a fixation fastener configured to mount in said adjustment interface;
- wherein when sufficient force is applied to said actuator said body catch disengages said movable ball end and said tool portion is released.
An adjustable disposable torque limiting device comprising:
- a handle with a tool containment interface formed on a side of said handle that is opposite of a side of said handle configured to be held;
- a fiist pin guide and a third pin guide formed through said handle;
- said tool containment interface comprising an annular wall and a closed end formed in said handle;
- an actuator with a force lever mounted in said tool containment interface, wherein said force lever is configured to be frangible;
- a tool portion configured to movably fit in at least part of said tool containment interface comprising:
- a work piece engaging region;
- a second pin guide formed in said tool portion;
- a guide slot formed in said tool portion;
- and
- a lever catch forming an interface with said force lever;
- a first pin configured to fit through said first pin guide in said handle and said second pin guide in said tool portion so as to connect said handle to said tool portion;
- a second pin configured to fit, through said third guide and move along said guide slot in said tool portion during rotational movement of said tool portion;
- a fixation fastener configured to mount in an adjustment interface;
- and,
- wherein when sufficient force is applied to said actuator, said lever catch disengages said force lever from said lever catch and the said portion is released from torque limiting provided by said actuator.
