摘要:
A power tool includes a housing, a trigger switch that is mounted to the housing, a tool output member and a motor and transmission assembly. The housing defines a handle. The motor and transmission assembly is coupled to the housing and is configured to drive the tool output member. The motor and transmission assembly include a motor, which is electrically coupled to the trigger switch, and a transmission having a transmission input member, which is drivingly coupled to the motor, and a transmission output member that is drivingly coupled to the tool output member. The motor and transmission are packaged in the housing in a manner that is extremely compact.

A tile cutting machine (10) includes a tool support assembly having at least one rail (76) with a rail bearing (66) associated therewith for selective movement there along. The rail bearing (66) includes a housing (74) having a bore therethrough. A plurality of slots (75) are located in the housing (74) adjacent the bore. The slots (75) receive an axle pin (70) having a wheel (68) thereon to provide a roller bearing. Portions of the wheels (68) extend into the bore and ride along an outer surface of the rail (76) when it is received in the bore.
摘要:
A battery pack with a housing, at least one battery cell contained within the housing, a first terminal and a second terminal. The housing includes a substantially ovoidal surface which is substantially symmetric about a first axis of symmetry and a second axis of symmetry which is transverse to the first axis. The surface has first and second substantially linear terminal openings. The first opening extends substantially parallel to and is non-coincident with the first axis, while the second opening extends substantially parallel to the second axis. The first and second terminals are disposed within the housing adjacent to the surface. The first terminal is accessible through first opening and the second terminal is accessible through the second opening. A device for using the battery pack is also provided.
摘要:
A method for controlling a fastening tool comprising: providing a transmission (16) having a flywheel (42) and a driver mechanism (18), said transmission configured to couple said flywheel to said driver mechanism one time in a driver sequence to cause energy to be transferred from said flywheel to said driver mechanism; determining an achievable rotational velocity of said flywheel based on a remaining number of flywheel rotations until an end of said driver sequence; and adjusting a position of said flywheel in said driver sequence based on said achievable rotational velocity.

A jigsaw (10) includes a housing (12) containing a motor (18) activated by a trigger assembly (20). A shoe member (30) is pivotally connected to the housing (12) of the jigsaw (10) and establishes an angle therebetween. The jigsaw includes a keel assembly (100) including a blade member (102) that generally extends from the housing (12) beyond the shoe member (30). The keel assembly (100) remains generally in line with the housing (12) as the angle between the shoe member (30) and the housing (12) varies. The jigsaw (10) also includes a latch assembly (122) capable of retaining and releasing the keel assembly (100) from the housing (12).

The adjustable guard assembly is connected to a head assembly of a string trimmer. The adjustable guard assembly includes a housing. The housing includes a mounting portion, which connects to a motor case. The housing further includes a deck portion, which extends from the mounting portion. The deck portion has a proximal end and a distal end. A first skirt member extends along and downward from the distal end of the deck portion in a generally radially outward direction. A first blade assembly includes a first blade member, provided in the interior of the first skirt member, to engage a rotating string member.
