Abstract:
1. A housing for an energy source for a hand-operated device, comprising: a fitting element which is detachably connectable with a head of the energy source for transmission of energy from the energy source to the device; a pusher element which is accessible from an exterior of the housing and is moveable in a first direction; and an ejecting element directly engaged with said pusher element and engageable with the energy source, an entirety of said ejecting element being driven by a movement of said pusher element in the first direction to move in a second direction, which is transverse to the first direction, for forcing the energy source to move in the second direction away from said fitting element and for causing the head of the energy source to be disconnected from said fitting element; wherein said ejecting element comprises an annular collar extending outside and around said fitting element and being adapted to extend outside and around the energy source and to directly engage the energy source for driving the energy source in the second direction away from said fitting element in response to the movement of said pusher element in the first direction; said housing further comprising an annular skirt which extends outside and around said fitting element, wherein said collar extends outside and around said annular skirt; and said annular skirt comprises a locking element for locking the energy source against rotation about an axis oriented in the second direction when the head of the energy source is connected to said fitting element.
