Screwdriving tool having a driving tool with a removable contact trip assembly
First Claim
1. A screwdriving tool comprising a driving tool, a contact trip assembly that is removably coupled to the driving tool by a bayonet-type mount, a sensor and a sensor target, the driving tool having a tool housing, a motor assembly and an output member that is driven by the motor assembly, the contact trip assembly having a nose element, one of the nose element and the output member being axially movable and biased by a spring into an extended position, one of the sensor and the sensor target being coupled to the tool housing, the other one of the sensor and the sensor target being coupled to the one of the output member and the nose element for axial movement relative to the one of the sensor and the sensor target, the sensor providing a sensor signal that is based upon a distance between the sensor and the sensor target, wherein the motor assembly is controllable in a first operational mode and at least one rotational direction based in part on the sensor signal, wherein the bayonet-type mount comprises a first mount structure, which is coupled to the tool housing of the driving tool, and a second mount structure that is coupled to a contact trip housing of the contact trip assembly, the first and second mount structures having lugs that are engagable to inhibit axial separation of the contact trip assembly from the driving tool.

Abstract
A screwdriving tool that includes a driving tool (driver), a sensor, a sensor target and a contact trip assembly that is coupled to the driving tool and has a nose element. The driver has a housing, a motor and an output member that is driven by the motor. One of the nose element and the output member is axially movable and biased by a spring into an extended position. The sensor and sensor target are configured to cooperate to permit the sensor to provide a sensor signal that is indicative of movement of the one of the nose element and the output member. The motor is controllable in a first operational mode and at least one rotational direction based in part on the sensor signal.

14. A power tool comprising:
-
a housing; a motor disposed in the housing; an output shaft at least partially disposed in the housing; a mechanical rotary impact mechanism disposed in the housing between the motor and the output shaft, the rotary impact mechanism including an input spindle rotatably driven by the motor, an anvil coupled for rotation to the output shaft, and a hammer received over the spindle and configured to selectively transmit rotational impacts to the anvil when an output torque exceeds a threshold value, wherein the rotary impact mechanism is configured to transmit rotational motion and rotational impacts from the motor to the output shaft; a control circuit for controlling delivery of power to the motor; a sensor coupled to the housing and electrically coupled to the control circuit; a contact trip assembly removably coupled to the housing and having a nosepiece; and a sensor target coupled to one of the output shaft and the contact trip assembly, wherein the one of the output shaft and the nosepiece is axially moveable between a first axial position and a second axial position relative to the housing to move the sensor target between a first target position and a second target position relative to the sensor, such that when the sensor target is in the first target position, the sensor causes the control circuit to control operation of the motor in a first mode and when the sensor target is in the second target position, the sensor causes the control circuit to control operation of the motor in a second mode. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
