Abstract
The present application discloses a shredder with a switch lock that locks the on/off switch in its on/off position.
Claims37
A shredder comprising:
- a housing;
- a shredder mechanism mounted in the housing and including an electrically powered motor and cutter elements, the shredder mechanism enabling articles to be shredded to be fed into the cutter elements and the motor being operable to drive the cutter elements so that the cutter elements shred the articles fed therein;
- a throat opening provided on the housing for enabling articles to be fed into the shredder mechanism;
- an on/off switch provided on an exterior of the housing and electrically coupled to the motor of the shredder mechanism, the switch including a manually engageable portion manually movable by a user's hand between at least (a) an on position wherein the switch enables delivery of electric power to the motor and (b) an off position disabling the delivery of electric power to the motor;
- a switch lock movable between (a) a locking position wherein the switch is locked in the off position and (b) a releasing position wherein the switch is released for movement from the off position;
- wherein the switch lock includes a manually engageable portion provided on the exterior of the housing, the manually engageable portion being manually movable by the user's hand to move the switch lock between the locking and releasing positions.

A shredder comprising:
- a shredder mechanism including an electrically powered motor and cutter elements, the shredder mechanism enabling articles to be shredded to be fed into the cutter elements and the motor being operable to drive the cutter elements so that the cutter elements shred the articles fed therein;
- an on/off switch electrically coupled to the motor of the shredder mechanism, the switch including a manually engageable portion manually movable by a user's hand between at least (a) an on position wherein the switch enables delivery of electric power to the motor and (b) an off position disabling the delivery of electric power to the motor;
- a switch lock movable between (a) a locking position wherein the switch is locked in the off position and (b) a releasing position wherein the switch is released for movement from the off position;
- a housing in which the shredder mechanism is received, the housing including an opening for enabling the articles to be shredded to be fed into the housing and into the cutter elements;
- a cover associated with the opening of the housing, the cover being movable between (a) a closed position covering the opening for preventing the articles to be shredded from being fed into the housing and into the cutter elements, and (b) an open position uncovering the opening for allowing the articles to be shredded to be fed into the housing and into the cutter elements;
- wherein the cover is linked with the switch lock such that the cover and the switch lock move together between (a) the open position of the cover and the releasing position of the switch lock and (b) the closed position of the cover and the locking position of the switch lock.

A shredder comprising:
- a shredder mechanism including an electrically powered motor and cutter elements, the shredder mechanism enabling articles to be shredded to be fed into the cutter elements and the motor being operable to drive the cutter elements so that the cutter elements shred the articles fed therein;
- an on/off switch electrically coupled to the motor of the shredder mechanism, the switch including a manually engageable portion manually movable by a user's hand between at least (a) an on position wherein the switch enables delivery of electric power to the motor and (b) an off position disabling the delivery of electric power to the motor;
- a switch lock movable between (a) a locking position wherein the switch is locked in the off position and (b) a releasing position wherein the switch is released for movement from the off position;
- wherein the switch lock includes a manually engageable portion manually movable by the user's hand to move the switch lock between the locking and releasing positions;
- wherein the switch lock is constructed such that, when the on/off switch is in the on position thereof, moving the switch lock from the releasing position to the locking position causes the switch to move into the off position;
- wherein the switch is also movable to a reverse position enabling delivery of electric power to the motor so as to operate the motor to drive the cutter elements in a reverse manner, the on position and the reverse position being on opposing sides of the off position,
- wherein the switch lock is also constructed such that, when the on/off switch is in the reverse position, moving the switch lock from the releasing position to the locking position causes the switch to move into the off position;
- wherein the switch lock includes a pair of camming surfaces, one of the camming surfaces being configured to cam the switch from the on position to the off position as the switch lock moves from the releasing position to the locking position, the other of the camming surfaces being configured to cam the switch from the reverse position to the off position as the switch lock moves from the releasing position to the locking position.
