Abstract
An apparatus has a part which can be moved to an operating position by an actuating device, in response to movement of a button to an on position. Upon movement of the part to its operating position, a latching member directly associated with the part latches the button in its on position. Upon sensing a predetermined condition in the apparatus, a control member prevents the transmission of the actuating movement by the actuating device to the part, and a user becomes aware that the part has not moved to its operating position because the button does not become latched in its on position.
Claims15
A mechanism for actuating an apparatus part, comprising
- at least one button arranged to be movable from an off-position to an on-position for selecting a mode of operation in the apparatus, and a return spring opposing movement of said button from said off-position to said on-position,
- at least one apparatus part,
- means for moving said part from a rest position to an operating position responsive to setting said button from its off-position to its on-position, said means for moving including an actuating device for moving said part to said on-position,
- means for starting said mode of operation responsive to said part being in its operating position,
- means for inhibiting said actuating device from moving said part to said on-position,
- a latching member, means for moving said member between a release position and a latching position, and means for latching said button in its on-position against the force of the return spring when said member is in its latching position, and
- at least one control member movable between a release position and a blocking position, in the blocking position said control member inhibiting movement of the latching member to its latching position, and causing said means for inhibiting to inhibit the transmission of actuating movement by the actuating device to said part,
- characterized in that said control member engages said apparatus part directly, and the latching member is mounted to the apparatus part for movement therewith, such that movement of the latching member into its latching position is controlled by the movement of the apparatus part to its operating position.

- at least one apparatus part,
- means for moving said part from a rest position to an operating position responsive to setting said button from its off-positin to its on-position, said means for moving including an actuating device for moving said part to said on-position,
- means for starting said mode of operation responsive to said part being in its operating position,
- means for inhibiting said actuating device from moving said part to said on-position,
- a latching member, means for moving said member between a release position and a latching position, and means for latching said button in its on-position against the force of the return spring when said member is in its latching position, and
- at least one control member movable between a release position and a blocking position, in the blocking position said control member inhibiting movement of the latching member to its latching position, and causing said means for inhibiting to inhibit the transmission of actuating movement by the actuating device to said part,
- characterized in that said apparatus part is arranged to be movable rectilinearly from its rest position to an intermediate position, and pivotally from said intermediate position to its operating position,
- said actuating device has an engaging portion movable along an actuation path in response to actuating movement of said device,
- said part has an engaging portion which is clear of said path when said part is in its rest position, and is disposed in said path when said part is in the intermediate position for engagement by the actuating device engaging portion during actuating movement of said device, for pivoting said part to its operating position, and
- said control member engages said apparatus part directly, and the latching member is mounted to the apparatus part for movement therewith, such that movement of the latching member into its latching position is controlled by the movement of the apparatus part to its operating position.
