Abstract
A desktop stapler having a feature for alignment of the anvil with the striker is disclosed. In one embodiment, a stapler body containing a striker is pivotably attached to a base. The pivoting rotation of the body causes a front-to-back motion of the striker over an anvil. A rib disposed at the back end of the body selectively pulls the back end of a linkage to the anvil backward as the body pivots downward to the stapling position. The anvil thus translates in relation to the body to maintain a close alignment of the striker over the anvil. The base assembly may include a cover plate slidable upon a base, wherein the cover plate includes the anvil. Another embodiment uses a tab that urges a staple track to be forcibly pulled open as the body is rotated away from the base.
Claims15
A desktop stapler, comprising:
- an elongated base assembly;
- a body pivotably attached to the base at a pivot location toward a rear end of the stapler, the base and the body extending forward from the pivotal attachment in a spaced relationship between the base and the body;
- an anvil slidably disposed on the base toward a front end of the stapler;
- a striker slidable within the body above the anvil;
- wherein the body includes a high position where the striker is spaced away from the anvil, and a low position where the striker is spaced near to the anvil;
- the pivot location is above the anvil by a pivot/anvil distance;
- the anvil translates between a forward rest position and a rearward position;
- and
- a pressing-surface of the body is linked to the anvil, and the pressing-surface of the body moves between a first position toward a second position as the body is pivoted from the high position toward the low position, wherein the anvil is translated from the forward rest position toward the rearward position through the link between the anvil and the pressing-surface.
A desktop stapler, comprising:
- a handle and body hinged to a base at a back end of the stapler;
- a striker disposed to move vertically within the body at a front end thereof;
- an anvil disposed to slide forward and rearward in the base and positioned generally underneath the striker, wherein the anvil is formed into a cover plate that is slidably disposed in an opening in the base;
- and
- means for selectively linking a back end of the body to the anvil;
- wherein the means for selectively linking urges the anvil to slide rearward as the body pivots toward the base thus maintaining vertical alignment of the anvil with the striker.
