Abstract

A handheld power tool charger, having at least one battery contact device is proposed, which is provided for charging at least one nondiscretely positioned handheld power tool battery. According to the invention, the battery contact device has at least one contact region which is embodied as elongated.

Claims

1. A handheld power tool charger which is provided for charging at least one nondiscretely positioned handheld power tool battery, the handheld power tool charger having at least one battery contact device that has at least one contact region which is embodied as elongated.

2. The handheld power tool charger as defined by claim 1, wherein the contact region is provided for contacting at least the handheld power tool battery displaceably in a main extension direction of the contact region.

3. The handheld power tool charger as defined by claim 1, further having a suspension device, which includes the contact region.

4. The handheld power tool charger as defined by claim 2, further having a suspension device, which includes the contact region.

5. The handheld power tool charger as defined by claim 1, wherein the contact region is provided for movably contacting a handheld power tool battery perpendicular to a main extension direction of the contact region.

6. The handheld power tool charger as defined by claim 2, wherein the contact region is provided for movably contacting a handheld power tool battery perpendicular to a main extension direction of the contact region.

7. The handheld power tool charger as defined by claim 3, wherein the contact region is provided for movably contacting a handheld power tool battery perpendicular to a main extension direction of the contact region.

8. The handheld power tool charger as defined by claim 4, wherein the contact region is provided for movably contacting a handheld power tool battery perpendicular to a main extension direction of the contact region.

9. The handheld power tool charger as defined by claim 1, wherein the battery contact device is provided for charging at least two handheld power tool batteries simultaneously.

10. The handheld power tool charger as defined by claim 8, wherein the battery contact device is provided for charging at least two handheld power tool batteries simultaneously.
