Abstract
A miniature spring-actuated stapler includes a tapered, flat power spring to store energy and eject staples. The power spring pivots at a rear of the stapler housing and includes three co-extensive arms terminating near the striker. As the L-shaped handle of the stapler is pressed, it acts on the center arm of the power spring to deflect it downward while the outer arms deflect upward. The arms are integral at a rear end and the outer arms are linked to the striker at the front. A tapered, flat reset spring disposed generally parallel to the power spring is used to reset the internal action. The housing includes open top and rear areas with the handle providing the enclosure thereof. A base assembly is slidably attached at a bottom of the stapler with an open position exposing a staple-loading chamber.
