Staple

A powered fastener driver including a housing, an inner frame positioned within the housing, and a workpiece contact assembly coupled to the housing and movable from an extended position to a retracted position in response to contact with a workpiece. The workpiece contact assembly includes a biasing element that biases the workpiece contact assembly into the extended position. The workpiece contact assembly is engageable with the inner frame in response to an applied force that moves the workpiece contact assembly beyond the retracted position.

Powered fastener driver

A fastener driver includes a housing defining a head portion and a handle portion, a drive mechanism positioned within the housing, and a firing mechanism. The firing mechanism includes a piston, a driver blade attached to the piston, a biasing member having a first end supported within the piston and a second end supported by the head portion, and a damper positioned between the firing mechanism and the head portion of the housing. The damper configured to attenuate one or more of noise or vibration from the firing mechanism as the driver blade moves from the top dead center position toward the bottom dead center position.

Staple collation

An insulated staple includes a staple including a crown extending between a pair of legs and an insulator including an insulator bridge extending between a pair of insulator legs and a channel extending from an end of one of the insulator legs to an end of the other of the insulator legs. The staple is at least partially received in the channel. A width of the channel at the insulator bridge is greater than a thickness of the staple crown. The insulator includes protrusions extending into the channel and defining therebetween a gap that, in absence of the staple, has a width less than the width of the staple crown to provide a friction fit between the staple crown and the insulator.

Insulated staple and staple collation

A fastener driver includes a housing defining a head portion and a handle portion, a drive mechanism positioned within the housing, and a firing mechanism. The firing mechanism includes a primary guide member supported within the head portion of the housing, a secondary guide member spaced from the primary guide member and supported within the head portion of the housing, a piston slidable along the primary guide member and the secondary guide member, a driver blade attached to the piston and configured to be movable along a drive axis, and a biasing member configured to move the piston and the driver blade from a top dead center (TDC) position toward a bottom dead center (BDC) position. A lifter assembly is operated by the drive mechanism to return the piston and the driver blade towards the TDC position, against the bias of the biasing member.
