Abstract
A desktop stapler uses a spring to store energy to install staples by impact blow. The force required to fasten papers together is reduced. A very compact mechanism is used, including a dual coil power spring with a nested lever. A multi-function base provides a sloped front all the way down to a desktop surface to guide paper sheets atop the base, easy access for lifting the stapler off a desk while in its horizontal or vertical resting positions, and integrated soft grip under surface. The base surrounds the rear of the stapler body to provide a smooth exterior so that the device is natural to use both horizontally and vertically. A simple re-set spring provides a smooth re-set action as the handle is raised. A staple track includes enlargement features to fit a larger staple pusher spring.
Claims17
A desktop stapler, comprising:
- an elongated base;
- a body pivotably attached to the base toward a rear end of the stapler wherein a closed position includes the base and the body extending forward from the pivotal attachment in a parallel and spaced relationship between the base and the body, the body being upright in the closed position;
- an open position of the stapler where the body is pivoted about the base to an upside down position, and the body extends rearward from the pivotal attachment;
- the base including two sidewalls that extend up to partially surround sides of the body, a rear wall of the base that joins the sidewalls from behind the body in the closed stapler position, the base thereby enclosing a lower rear end of the body in the closed stapler position;
- and
- the lower rear end of the stapler being above the pivotal attachment and exposed outside the base in the open stapler position.
A desktop stapler, comprising:
- an elongated base;
- a body pivotably attached to the base toward a rear end of the stapler wherein a closed position includes the base and the body extending forward from the pivotal attachment in a parallel and spaced relationship between the base and the body, the body being upright in the closed position;
- an open position of the stapler where the body is pivoted about the base toward a rearward body position;
- the pivotal attachment is at a post, the post fitting into a hinge connection recess;
- and
- the post includes an end tapered to a small diameter, the hinge connection recess includes a respective tapered small diameter recess end, and the post small diameter end presses the small diameter recess end.
A desktop stapler, comprising:
- an elongated base;
- a body pivotably attached to the base toward a rear end of the stapler having a closed position with the base and the body extending forward from the pivotal attachment in a parallel and spaced relationship and an open position of the stapler where the body is pivoted about the base toward a rearward body position;
- means for ejecting staples from the body held inside the body;
- a staple guide track holding staples and slidably disposed in the body beneath the means for ejecting staples, wherein the staple guide track includes an extension projecting from a rear end thereof;
- parallel sidewalls of the base extending on opposite sides of the body at the rear end of the stapler;
- complementary means for pivotal attachment of the base and the body, disposed on the sidewalls and the body;
- and
- a back wall joining the sidewalls and at least enclosing the track pull, wherein the back wall selectively engages the extension of the track pull creating a detent as the body is pivoted against the base between the open and closed positions.
A desktop stapler, comprising:
- an elongated base;
- a body pivotably attached to the base at a rear end of the stapler having a closed position with the base and the body extending forward from the pivotal attachment in a parallel relationship, and an open position of the stapler where the body is pivoted about the base toward a rearward body position;
- spring energized means for ejecting staples from the body held inside the body;
- a staple guide track holding staples disposed beneath the spring energized means for ejecting staples, wherein the staple guide track includes an extension projecting from a rear end thereof;
- opposed sidewalls of the base extending on opposite sides of the body at the rear end of the stapler;
- complementary means for pivotal attachment of the base and the body, disposed on the sidewalls and the body;
- and
- a back wall joining the sidewalls, wherein the back wall selectively engages the extension of the track pull creating a detent as the body is pivoted against the base between the open and closed positions.
