Latching arrangement for battery pack

A latching arrangement for latching a battery pack to an electric device wherein the battery pack is insertable into the device along an axis to an operating position, said latching arrangement comprising:

• two latching shoulders respectively disposed on opposite sides of the device, each of said shoulders having a first latching surface inclined with respect to the axis at a predetermined angle, and a latching member disposed on one side of the battery pack and adapted for cooperation with the latching shoulder on the corresponding side of the device, said latching member being displaceable between latching and release positions and resiliently biased to the latching position, said latching member having two second latching surfaces thereon respectively inclined with respect to the axis on opposite sides thereof at said predetermined angle, whereby when the battery pack is in its operating position one of said second latching surfaces is engageable with said first latching surface of the one of said shoulders on the corresponding side of the device irrespective of the side of the battery pack on which said latching member is disposed.

A latching arrangement for latching a battery pack on an electric device having a body portion extending along a first axis and a handle portion inclined with respect to the first axis, wherein the battery pack is insertable into the handle portion of the device along a second axis to an operating position, said latching arrangement comprising:

• two latching shoulders respectively disposed on opposite sides of the device, each of said shoulders having a first latching surface disposed substantially parallel to the first axis, and a latching member disposed on one side of the battery pack and adapted for cooperation with the latching shoulder on the corresponding side of the device, said latching member being displaceable between latching and release positions and resiliently biased to the latching position, said latching member having two second latching surfaces thereon respectively inclined with respect to the second axis on opposite sides thereof at a predetermined angle, said predetermined angle being such that when the battery pack is in its operating position one of said second latching surfaces is substantially parallel to and engageable with said first latching surface on the one of said shoulders on the corresponding side of the device irrespective of the side of the battery pack on which said latching member is disposed.
