摘要:
A fastener driving device (10) includes a frame, a fastener driver (33) reciprocally mounted in the frame, and a trigger assembly (39). The trigger assembly (39) includes a trigger lever (51) configured to be moved to an actuated position to actuate the fastener driving device (10), a mode selector (60) rotatably mounted to the frame, the mode selector (60) being configured to move to select a mode of operation of the fastener driving device (10), and a trigger lock (64) mounted to the frame, the trigger lock (64) being movable between a first position wherein actuation of the trigger lever (51) is permitted and a second position wherein actuation of the trigger lever (51) is prevented. In the first position, the trigger lock (64) engages the mode selector (60) to prevent the mode selector (60) from moving. In the second position, the trigger lock (64) disengages the mode selector (60) to permit movement of the mode selector (60) to select the mode of operation of the fastener driving device (10).

A fastener driving tool (10) includes a housing assembly (12) with a nosepiece assembly (18) defining a drive track (28). A safety trip assembly (60) includes a trigger enabling portion (62) and a workpiece engaging portion (64) and is movable between an extended disabling position and a retracted enabling position. The safety trip assembly (60) is biased toward the extended position and is moved toward the retracted position by engagement between a workpiece and the workpiece engaging portion (64). The workpiece engaging portion (64) is movable to permit adjustment of a length of the safety trip assembly (60). The workpiece engaging portion (64) may be removed from the safety trip assembly (60) and exchanged with another different workpiece engaging portion (64). A workpiece engaging portion (64) usable with the fastener driving tool (10) includes a positioning mechanism having an opening locating structure (61) and a guiding structure (65).
摘要:
A hammer-type stapler in which the staple driving element (24) and the staple drive track defining structure (18) are constructed and arranged with respect to the frame structure (12) to move through a drive stroke incident to an operator grasping a handle portion (14) and manually impacting the staple drive track defining structure (18) on a workpiece to arrest the movement of the drive track structure (18) on the workpiece while the frame structure (12) and the staple driving element (24) continue to move toward the workpiece with respect to the arrested drive track structure 18. The staple driving element (24) is constructed and arranged with respect to the frame structure (12) and the drive track structure (18) such that the continued movement of the staple driving element (24) toward the workpiece with respect to the arrested drive track structure (18) is further and faster than the continued movement of the frame structure (12) toward the workpiece with respect to the arrested drive track structure (18) enabling the staple driving element (24) to effect a drive stroke through the drive track (18) and to drive a staple therein into the workpiece while the frame structure (12) is undergoing a relative movement with respect to the drive track structure (18) which is less than substantially equal to the relative movement of the staple driving element (24) with respect to the drive track structure (18) during the drive stroke of the staple driving element.

A fastener driving device (10) includes a housing containing a chamber (20) for storing compressed air a cylinder structure (34) disposed within the housing, a piston (26) movably disposed within the cylinder, a driver (33) connected to the piston, a main valve (38) cooperable with the cylinder structure and movable between an open position and a closed position. The main valve (38) in its open position allows air to move the piston through a drive stroke. The fastener driving device also includes a trigger valve (36) operable between first and second positions. The trigger valve in its first position communicates air pressure from the chamber (20) to the main valve (38) through a signal passageway (43) so as to retain the main valve in a closed position. The trigger valve in its second position allows the air to be exhausted to atmosphere through the signal passageway (43) to permit the main valve to open. The cylinder (34) and the signal passageway (43) comprise an integrally molded structure.
摘要:
The movement of the enabling member (74) through the second arcuate path thereof is operable to allow the actuating move into the inoperative position thereof. When the enabling member (74) is in the third position thereof, it is biased to move through a third arcuate path by the release of the trigger member (42). The third arcuate path of movement of the enabling member (74) is configured to move the opposite end of the enabling member (1) into a position overlying the upper end (82) of the upper structure (84) when the upper structure (84) is disposed in the inoperative position thereof and (2) into abutting engagement with the upper structure (84) when the upper structure is in the operative position thereof.
摘要:
A fastener driving tool (10) includes a housing assembly (12) with a nosepiece assembly (18) defining a drive track (28). A driving mechanism (26) is housed within the housing assembly (12) to drive a fastener through the drive track (28) and into a workpiece in response to a trigger (37). The tool includes a safety trip assembly (60) which includes a trigger enabling portion (62) and a workpiece engaging portion (64) and is movable between an extended disabling position and a retracted enabling position. The safety trip assembly (60) is biased toward the extended position and is moved toward the retracted position by engagement between the workpiece and the workpiece engaging member (78). The workpiece engaging portion (64) is movable to permit adjustment of a length of the safety trip assembly (60).
摘要:
A clip and collected assembly thereof are provided and including a method of forming the clip and clip assembly. The clip (12) is formed with at least one slot (16) that has at least one projection for keeping a resilient cord press fit in the slot therein against forces tending to shift it out therefrom. Preferably, two parallel slots (12) are provided for receiving two cords (14) therein with there being two opposing projections (58,60) extending into the slot (12) opening from either side of the slot. The slot projections (58,60) provide an attendant manufacturing benefit as the punches (78) of the die press apparatus that punch slugs from the blank fed thereto will not suffer from slug pulling problems because of the presence of corresponding projections (58,60) extending into the die cavity openings from either side thereof. In addition, while the clearances between the projection of the die cavity and the punches (78) are at normal tight tolerances, the clearance between the cavity sides (84,86) and ends and the punches (78) are oversized so that burrs are formed on the corresponding clip slot (16) sides and ends for gripping the cord (14) and providing additional resistance to shifting in the slot. Improved configurations for the cords (14) are also provided to meet the tolerances required for the press fit in the slots (12) and to be readily severed by an application tool (34). Special shapes for the slot ends can be provided so that as the cords (14) are press fit therein, areas of weakness will be created in the cords to assist in the severing thereof. Preferred cord materials include those that will not bead when run through spring tempering heat treat ovens, such as nylon and PBT.
摘要:
A fastener device (100) includes a multistage solenoid (102), a magnetic driver (116), and a controller (120). The magnetic driver (116) is configured to travel through the multistage solenoid (102). Each stage (106, 108) of the multistage solenoid (102) is configured to be selectively energized to generate a first electromagnetic field and a second electromagnetic field, the second electromagnetic field having a polarity different from the first electromagnetic field. Each stage (106, 108) is also configured to be selectively de-energized. The controller (120) is configured to adjust an amount of force the multistage solenoid (102) imparts on the magnetic driver (116) while the magnetic driver (116) travels between the a stage (106) and a second stage (108) of the multistage solenoid (102), by combining a magnetic field of the magnetic driver (116) with at least a portion of a first electromagnetic field of the first stage (106) and at least a portion of a second electromagnetic field of the second stage (108).
