20080223902 | EASY STAPLER - An effort-saving stapler includes a shell, a magazine, a hammer, an elastic element, a block, a trigger and an extensive element. The magazine is disposed in the shell for supporting and feeding nails. The hammer is disposed in the shell for hammering the nails, one at a time. The elastic element is disposed in the shell for biasing the hammer. The block is disposed in the shell. The trigger is movably and pivotally connected to the shell and engaged with the block at an engagement point. The extensive element includes a first end connected to the hammer and a second end telescopically connected to the trigger. When the trigger is operated, the hammer is lifted by the extensive element and the engagement point is moved towards the hammer. | 09-18-2008 |
20090120993 | STAPLER - A stapler movable between a rest position and a stapling position and having a front end and a rear end. The stapler includes a base, a staple magazine coupled to the base and configured to hold staples, and a driver blade operable to drive staples out of the staple magazine during stapling operations. The stapler further includes an elastic member coupled to the driver blade and operable to move the driver blade during stapling operations. The elastic member utilizes potential energy to move the driver blade during stapling operations. The driver blade is positioned above the staple magazine when the stapler is in the rest position and the magazine is extendable from the front end of the stapler to allow a user to load staples in the magazine. The stapler is configured such that only the potential energy of the elastic member can operate the driver blade during stapling operations. | 05-14-2009 |
20090159638 | SPRING POWERED STAPLER - This invention provides a spring powered stapler comprising a power spring having a front and a rear end, the rear end of the power spring being limited from moving frontward, a middle section between the front and rear end of the power spring being bent down while the front and rear end of the power spring maintaining in upper positions for storing energy in the power spring, and the front end of the power spring moving rearward as a result of the middle section of the power spring being bent down, and a lock plate, while not moving, holding up the front end of the power spring before the rearward movement of the front end of the power spring exceeding a predetermined distance and releasing the front end of the power spring after the rearward movement of the front end of the power spring exceeding the predetermined distance. | 06-25-2009 |
20090184150 | Desktop Stapler - A desktop stapler comprises a base member including a restricting unit; a magazine including a plunger disposed on the head thereof; two linkage devices, with each linkage device including a first hole, a third hole, a second hole formed on a bent between the first and third holes, and a pivot hole, with each pivot hole adapted to connect with the base member via the restricting unit; a press member including a press portion defined on the bottom of an end thereof a grip portion defined on another end thereof and connecting to the plunger of the magazine, and two pivot holes formed on two sidewalls thereof and connect to the third holes of the linkage devices respectively via a coupler unit; a guide member including a first end that is inserted via a coupler unit, a second end defining a press end, and two second pivot holes formed on two sidewalls thereof and opposite to each other. | 07-23-2009 |
20120012635 | STAPLER FOR PREVENTING SIMULTANEOUS DISPENSING OF MULTIPLE STAPLES - Staplers and methods of stapling are described. The stapler includes a topsail configured to support a plurality of staples, the staples being slidably moveable on the topsail; a blade configured to drive an end staple of the plurality of staples out of the stapler and into an object to staple; a pusher configured to urge the plurality of staples on the topsail in a direction toward the blade; a finger configured to move between at least two positions by movement of the blade, a first position where the finger does not substantially counter action of the pusher, and a second position where the finger is engaged with the plurality of staples to substantially counter action of the pusher on the staples to keep the plurality of staples excluding the end staple away from the blade. | 01-19-2012 |
20130299548 | CORDLESS FRAMING NAILER - A driving tool with a driver and a motor-driven flywheel that can be engaged by the driver to propel the driver along a driver axis. The driving tool includes a return mechanism with a rail onto which the driver is received. The rail extends parallel to the driver axis. | 11-14-2013 |
