  • 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: 20080237293
    Abstract: [Object] To provide a stapler for fastening papers or the like, which can perform a proper stapling operation even though a handle thereof is given smaller force, can perform a stronger stapling operation, can reduce the production cost due to fewer parts and simple structure, and has a structure in which a structure in which staples does not accidentally pop out when refilling staples. [Solve] By pushing down a handle, a trigger member moves a puller or pusher member, and the movement of the puller or pusher member moves a fulcrum shaft B, which results in that an angle formed by a fulcrum shaft A, the fulcrum shaft B, and a fulcrum shaft C becomes closer to 180 degrees. In accordance with this, one end of a driver spring moves to the upper side to save power in the driver spring, and by pushing down the handle, the engagement between the trigger member and the puller or pusher member is released.

  • 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.

  • Publication number: 20060086771
    Abstract: A cassette of a cassette type stapler, wherein a holder structural body (1), staple guides (8), and a spring engaging device (9) of the holder structural body are molded integrally with each other, a spring is fitted to the spring engaging device (9) of the holder structural body and the feeder projection (21) of a feeder (20), and the feeder (20) pushes a staple forward. Namely, a mechanism functioning as a conventional outer box is formed integrally with a mechanism guiding the staple. Also, in the mechanism functioning as the outer box, a rear wall or a bottom wall is not separated from the outer box but formed integrally therewith. In addition, a structure to directly engage one end of the spring with a holder body and the other end with the feeder and a structure to guide the staple to a specified position when the staple is struck out are used for the mechanism guiding the staple. A member for engaging the spring with the holder body and a staple guide member are required for these structures.
