Abstract

A nailing machine includes a driver guide mounted on a body. A driver is provided and is reciprocally movable within a nail guide channel formed within the driver guide. A nail magazine is mounted on the driver guide and includes therein a nail storing channel in communication with the nail guide channel. A pusher is disposed within the nail storing channel for pressing nails stored therein toward the nail guide channel. The pusher is movable within the nail storing channel according to the amount of nails stored within the nail storing channel. A trigger is mounted on the body and is operably by an operator to move between a starting position for actuating the drive device of the driver and a stopping position for stopping the same. A stopper is connected with the trigger and is movable between a first position corresponding to the starting position of the trigger and a second position corresponding to the stopping position. An engaging member is disposed within the nail magazine and is movable with the pusher. The engaging member is engageable with the stopper positioned at the second position so as to prevent movement of the trigger from the second position to the first position when the amount of the nails stored within nail storing channel is less than a predetermined amount.

Dependent claims

A nail machine comprising:

a body;
a driver guide mounted on said body and including a nail guide channel therein;
a driver reciprocally movable within the driver guide by a drive device disposed within said body;
a nail magazine mounted on said driver guide and including therein a nail storing channel in communication with said nail guide channel;
a pusher disposed within the nail storing channel for pressing nails stored therein toward said nail guide channel in such a manner that each nail can be in turn driven out of said nail guide channel by the reciprocal movement of said driver, the pusher being movable within said nail storing channel according to the amount of nails stored within said nail storing channel;
a trigger mounted on said body and operable by an operator to move between a starting position for actuating said drive device of said driver and a stopping position for stopping the same;
a stopper directly connected with said trigger at one end and having an engagement portion at the other end, said stopper movable between a first position corresponding to the starting position of said trigger and a second position corresponding to said stopping position in such a manner that said stopper is moved from said second position to said first position in response to the actuation of said trigger from said stopping position to said starting position;
and
said pusher including an engaging member disposed within the nail magazine and movable with the pusher, said engaging member being engageable with the stopper engagement portion when positioned at the second position so as to prevent movement of the trigger from said stopping position to said starting position when the amount of the nails stored within said nail storing channel is less than a predetermined amount.

A nailing machine comprising:

a body;
a driver guide mounted on said body and including a nail guide channel therein;
a driver reciprocally movable within said driver guide by a drive device disposed within said body;
a nail magazine mounted on said driver guide and including therein a nail storing channel in communication with said nail guide channel;
a pusher disposed with said nail storing channel for pressing nails stored therein toward said nail guide channel in such a manner that the nails can be in turn driven out of said nail guide channel by the reciprocal movement of said driver, said pusher being movable within said nail storing channel according to the amount of nails stored within said nail storing channel;
a trigger mounted on said body and operable by an operator to move between a starting position for actuating said drive device of said driver and a stopping position for stopping the same;
a stopper forming an integral part with said trigger and movable between a first position corresponding to said starting position of said trigger and a second position corresponding to said stopping position in such a manner that said stopper is moved from said second position to said first position in response to the actuation of said trigger from said stopping position to said starting position;
and
an engaging member disposed within said nail magazine and movable with said pusher, said engaging member being engagement with said stopper when positioned at said second position so as to prevent movement of said trigger from said stopping position to said starting position when the amount of the nails stored within said nail storing channel is less than a predetermined amount;
said nail storing channel of said nail magazine extending substantially perpendicular to said nail guide channel of said driver guide;
said pusher being movable within said nail storing channel in a longitudinal direction thereof;
said stopper extending from said trigger perpendicular to said nail storing channel to said nail magazine and has one end fixedly connected with said trigger and the other end extended within said nail storing channel through said nail magazine for engagement with said engaging member;
said one end of said stopper including a slot at a position opposed to said engaging member in a longitudinal direction of said nail storing channel for engagement with said engaging member;
said slot of said one end of said stopper including a first slot formed perpendicular to a longitudinal direction of said stopper and a second slot extending from said first slot in the longitudinal direction of said stopper;
said second slot being formed on a side of said one end of said stopper opposed to said engaging member;
said engaging member engaging only said second slot so as to permit movement of said stopper from said second position to said first position when the amount of said nails exceeds at least said predetermined amount;
and
said engaging member engaging said first slot beyond said second slot so as to prevent movement of said stopper from said second position to said first position when the amount of said nails is less than said predetermined amount.
