摘要:
A hammer-type stapler in which the staple driving element (24) and the staple drive track (18) defining structure 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 on a workpiece. The direction of guided movement of a staple stick along the staple feed track is at an angle greater than 90o with respect to the direction of the drive stroke of the staple driving element (24) within the staple drive track (18), the arrangement being such that the leading staple will be driven into the workpiece in the direction of the drive stroke enabling the hand grip portion to be positioned for manual gripping so that the knuckles are spaced from a flat workpiece surface in which a staple has been driven generally perpendicularly therein.

The present invention relates to a glue gun (10) for selectively supply molten adhesive. The glue gun comprises a housing (12), an actuator (16) movable between actuated and non-actuated positions, and a nozzle (18) configured to allow molten adhesive to flow therethrough. The housing includes an adhesive receiving chamber (27) fluidly communicating with the nozzle. The chamber (27) has an opening at one end thereof for allowing a supply of solidified adhesive to be inserted into said chamber. A heating element is associated with the chamber. The heating element (80) is operable to apply heat to the lead end portion of the solidified adhesive supply sufficient to melt the lead end portion when an electric signal is applied to the heating element. A heating element controller operates to allow the electric signal to flow to the heating element for a period of time after the actuator has been moved to its non-actuated position and to thereafter prevent the electric signal from flowing through the heating element at the end of the time period. The present invention also relates to a timing circuit for controlling the amount of time during which an electric signal is supplied to an operative element.

A dry fire lockout assembly for a fastener driving device includes a bypass feature. A link is movably mounted to an upper contact arm and interconnected with a lower contact arm when the link is in a first orientation. The link includes a dry fire lockout portion. A dry fire lockout portion of a lifter is configured to engage the dry fire lockout portion of the link, when a supply of fasteners in the fastener driving device is less than a predetermined number of fasteners, and move the link against the bias of the biasing member to a second orientation in which the link is not interconnected with the lower contact arm.

Tool-free adjustment members in a fastener driving tool (2). The fastener driving tool can be used to seal closed containers such as, for example, corrugated fiberboard cartons, by applying staples to the folded flaps or other closure parts to secure them in place. The tool-free adjustment members (5, 7, 9) provide customizable drive settings for a variety of different sized staples and different workpiece conditions.

A metal connector adaptor for a fastening tool having a body including a drive channel extending therethrough. A pendulum member is pivotably connected to the body within the drive channel and biased toward a front portion of the drive channel. A pair of claws is pivotably connected to the body and can surrounding the drive channel so as to retain a lower contact arm of the fastening tool. A guide member protrudes from the lower portion of the body to align the adaptor with designated holes in a metal connector.

An apparatus and methods for clinching nails into workpieces are provided. The apparatus can include a housing assembly including a driving assembly capable of driving a fastener. A nose piece can be arranged with the housing assembly and can define a fastener drive track. A clinching assembly can be arranged with the housing assembly and can include a movable anvil including an anvil tip portion. The movable anvil is capable of being moved into a position whereby the workpieces are held between the anvil tip portion and the nosepiece, while the anvil tip portion is operable to bend a fastener tip into one of the workpieces after being driven through the workpieces.

A fastening tool includes an actuation device configured to actuate a drive engine of the tool to initiate a drive stroke. The actuation device includes a contact trip assembly operatively connected to the movable portion of the nose assembly. The contact trip assembly a lower contact arm connected to the movable portion of the nose assembly biased in the retracted position and movable to the extended position with the moveable portion of the nose assembly, and an upper contact arm operatively connected to the lower contact arm. The actuation device includes a trigger assembly that includes a trigger, a trigger arm pivotally supported by the trigger and configured to interact with the upper contact arm, and a check pawl configured to engage an opening in the upper contact arm when the upper contact arm moves downward to prevent the tool from being operated in a contact trip mode.
