Battery-powered hand-guided power tool

A battery-powered, hand-guided power tool in which a rechargeable battery pack is releasably connected, which comprises:

• a tool housing;
• a rail-and-channel structure formed with a longitudinal extent between opposite ends thereof, for facilitating the assembly of the battery pack in an operative position on the tool housing;
• a locking device located on the tool housing for locking the battery pack with the housing in the operative position, and including a latch structure which is locatable between a device-latched position, coincidental with the operative position of the battery pack, and a device-release position;
• a plurality of electrical battery contacts located on the battery pack;
• a plurality of electrical tool contacts located on the tool housing;
• the battery contacts and the tool contacts having a prescribed contact length along which they electrically engage;
• the battery contacts and the tool contacts extending in a direction along the longitudinal extent of the rail-and-channel structure, and being electrically connected when the battery pack is in the operative position;
• the battery pack being movable from the operative position into a battery release position when the latch structure is moved from the device-latched position to the device-release position to permit the battery pack to be moved in the direction of the longitudinal extent of the rail-and-channel structure for removal from the tool housing;
• a spring located on the tool housing and positioned to apply a spring-loaded force to the battery pack in the operative position in a direction of a displacement movement of the battery pack out of the operative position;
• and
• the spring being expandable by a distance greater than the prescribed contact length, and the restoring force of the spring when extended to the prescribed contact length being greater than the weight of the battery pack.
