  • Patent number: 7681771
    Abstract: 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.

  • Publication number: 20070057011
    Abstract: A desktop stapler includes a base configured to rest on a support surface, a cover, and a magazine. The stapler further includes an elastic member, a driver blade, and a support member. The elastic member is positioned at least partially between the cover and magazine and stores energy applied to the cover as the cover is moved relative to the magazine. The driver blade is coupled to an end of the elastic member and is configured to push out staples from the magazine. The support member selectively engages the elastic member and energy is stored in the elastic member as the cover is moved relative to the magazine. The elastic member is engaged with a portion of the support member. Energy stored in the elastic member is released when the elastic member disengages from the portion of the support member, causing the driver blade to push out a staple.
