Abstract
A trigger mechanism for a fastening tool having a spring curl trip actuator. The spring curl trip actuator can be made of a flexible material and can be configured to exert a force upon a trigger switch. The spring curl trip actuator can also absorb force from a contact trip. The spring curl trip actuator can have compact height and length dimensions. The fastening tool can use a method for controlling triggering by using a spring curl trip actuator.
Claims26
A method for controlling a switching of a trigger switch of a fastening device, comprising the steps of:
- providing a fastening device having a trigger switch;
- providing a contact trip mechanism;
- providing a spring curl trip actuator having an actuator spring curl;
- applying an activating force to at least a portion of the spring curl trip actuator from the contract trip mechanism;
- moving at least a portion of the spring curl trip actuator mechanism to impart a force in a range of from 1 N to 40 N to the trigger switch;
- and
- switching the trigger switch.
A fastening device, comprising:
- a trigger mechanism for triggering the fastener device to drive a fastener into a workpiece;
- the trigger mechanism having a spring curl trip actuator and a trigger switch;
- wherein the spring curl trip actuator comprises an actuator spring curl;
- wherein the actuator spring curl has a portion which is configured to curl radially about at least a portion of an actuator hub;
- and
- wherein the spring curl trip actuator is configured to switch the trigger switch when at least a portion of the spring curl trip actuator receives an activating force.
A fastening device having a means of absorbing force from a contact trip mechanism, comprising:
- a means for absorbing force imparted by a contact trip, the means for absorbing force being configured between the contact trip and a trigger switch,
- the means for absorbing force adapted to absorb an amount of force from the contact trip such that the force transferred to the trigger switch has a value of a range of from 1 N to 40 N.
A fastening device, comprising:
- a trigger mechanism for triggering the fastener device to drive a fastener into a workpiece;
- the trigger mechanism having a spring curl trip actuator and a trigger switch;
- wherein the spring curl trip actuator comprises a flexible material having a specific gravity in a range of from 1.1 to 3.0;
- and
- the spring curl trip actuator configured to switch the trigger switch when at least a portion of the spring curl trip actuator receives an activating force.
