Abstract
The housing is intended to receive a source introduced by means of its head and pushed into a position ensuring good transmission of energy. The housing includes a mechanism for converting a transverse movement towards the interior of the housing imparted by a pusher element of the mechanism accessible from the exterior of the housing into an orthogonal movement for ejection of the source.
Claims10
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.

A housing for a gas fastening device, said housing comprising:
- a fitting element which is detachably connectable with a head of a gas cartridge for supplying gas to said device;
- a pusher element which is accessible from an exterior of the housing and is moveable in a direction transverse to an axial direction of said housing;
- and
- an ejecting mechanism engageable with both said pusher element and the gas cartridge;
- wherein said ejecting mechanism is moveable in the axial direction in response to a movement of said pusher element in the transverse direction for ejecting the gas cartridge in the axial direction away from said fitting element and causing the head of the gas cartridge to be disconnected from said fitting element;
- wherein said ejecting mechanism is moveable in the axial direction in response to the movement of said pusher element in the transverse direction even when the gas cartridge is not in the housing;
- one of said ejection mechanism and said pusher element has a surface slanted with respect to both the transverse and axial directions;
- and
- the other of said ejection mechanism and said pusher element is in direct contact with and slidable on said surface in the movement of said pusher element in the transverse direction to cause an entirety of said ejection mechanism to move in the axial direction.

- a fitting element which is detachably connectable with a head of a gas cartridge for supplying gas to said device;
- a pusher element which is accessible from an exterior of the housing and is moveable in a direction transverse to an axial direction of said housing;
- and
- an ejecting mechanism engageable with both said pusher element and the gas cartridge;
- wherein said ejecting mechanism is moveable in the axial direction in response to a movement of said pusher element in the transverse direction for ejecting the gas cartridge in the axial direction away from said fitting element and causing the head of the gas cartridge to be disconnected from said fitting element;
- wherein said ejecting mechanism is moveable in the axial direction in response to the movement of said pusher element in the transverse direction even when the gas cartridge is not in the housing;
- said housing further comprising
- a locking element for locking the gas cartridge against rotation about an axis oriented in the axial direction when the head of the gas cartridge is connected to said fitting element;
- and
- a ramp for guiding the gas cartridge being pushed toward said fitting element to rotate about said axis until the gas cartridge is locked against rotation by said locking element;
- wherein
- said locking element comprises a channel at an end of said ramp and being elongated in the axial direction for allowing the gas cartridge, after being locked against rotation in said channel, to linearly move in the axial direction toward said fitting element until said fitting element is connected with the head of the gas cartridge.

In combination, a housing for a gas fastening device and a gas cartridge received in said housing for supplying gas to said device;
- wherein said housing comprises:
- a fitting element detachably connected with a head of the gas cartridge for gas transmission to said device;
- a pusher element which is accessible from an exterior of the housing and is moveable in a direction transverse to an axial direction of said housing;
- and
- an ejecting mechanism directly engaged with both said pusher element and the gas cartridge for directly converting a transverse movement of said pusher element in the transverse direction into an axial movement of said gas cartridge in the axial direction away from said fitting element, said axial movement being sufficient to cause the head of said gas cartridge to be disconnected from said fitting element;
- wherein
- said ejecting mechanism moves in the axial direction along with said gas cartridge in response to the transverse movement of said pusher element in the transverse direction;
- one of said ejection mechanism and said pusher element has a surface slanted with respect to both the transverse and axial directions;
- and
- the other of said ejection mechanism and said pusher element is slidable on said surface in the transverse movement of said pusher element to cause said axial movement of both said ejecting mechanism and said gas cartridge.
