Latch mechanism for a battery operated power tool

A battery operated tool comprising:

• a power tool housing having a latching surface formed into an outer surface of the power tool housing;
• a battery pack having a housing to hold battery cells to power the tool;
• and
• a battery latch mechanism to removably attach the battery pack to the power tool housing, the battery latch mechanism including a latching member with an outer side and an inner side, a latching flange extending from the inner side at one end of the latching member and a pushing surface on the outer side toward an opposing end of the latching member wherein the latching member is biased between an engaged position where the flange is removably connected onto the latching surface and a release position where the flange is disconnected from the latching surface by depressing on the pushing surface.

A battery latch mechanism to removably attach a battery pack to a power tool having a housing, the battery latch mechanism comprising:

• a latching member having a latching flange at one end, a pushing surface toward an opposing end and a pivot axis between the flange and pushing surface;
• a spring engaged with the latching member opposing the pushing surface;
• wherein the latching member pivots about the pivot axis between an engaged position where the flange is connected to the power tool and a release position where the flange is disconnected from the power tool by depressing on the pushing surface thereby moving the spring;
• and
• wherein the distance between the latching surface and the pivot axis is greater than the distance between the pivot axis and the pushing surface.
