US 7946514 B2Abstract
A shredder includes a thickness detector device having a contact portion in a throat of a housing. The contact portion is movable by a thickness between opposing major surfaces of at least one article being received by the throat. The thickness detector device includes a detectable portion movable by the contact portion, and a detector for detecting at least one position of the detectable portion that includes a position when the detectable portion has been moved by the contact portion by an amount that correlates to a predetermined maximum thickness. A controller is coupled to the thickness detector, is operable to prevent a motor from driving cutter elements in a shredding direction responsive to the detector detecting that the detectable portion has been moved by the amount that correlates to the predetermined maximum thickness, and is configured to vary the predetermined maximum thickness based on receiving an input parameter.
This application is continuation of U.S. patent application Ser. No. 11/767,152, filed Jun. 22, 2007 and currently pending, which is a divisional application of U.S. patent application Ser. No. 11/444,491, filed Jun. 1, 2006 and currently pending, which is a continuation-in-part of U.S. patent application Ser. No. 11/177,480, filed Jul. 11, 2005 and currently pending, which in turn is a continuation-in-part of U.S. patent application Ser. No. 10/937,304, filed on Sep. 10, 2004 and issued on Dec. 25, 2007 as U.S. Pat. No. 7,311,276, the entire contents of which are all incorporated herein by reference. U.S. patent application Ser. No. 11/444,491, filed Jun. 1, 2006 and currently pending is also a continuation-in-part of U.S. patent application Ser. No. 11/385,864, filed on Mar. 22, 2006 and currently pending, the entire content of which is also incorporated herein by reference.
FIGS. 1 and 2 illustrate a shredder constructed in accordance with an embodiment of the present invention. The shredder is generally indicated at 10. In the illustrated embodiment, the shredder 10 sits atop a waste container, generally indicated at 12, which is formed of molded plastic or any other material. The shredder 10 illustrated is designed specifically for use with the container 12, as the shredder housing 14 sits on the upper periphery of the waste container 12 in a nested relation. However, the shredder 10 may also be designed so as to sit atop a wide variety of standard waste containers, and the shredder 10 would not be sold with the container. Likewise, the shredder 10 could be part of a large freestanding housing, and a waste container would be enclosed in the housing. An access door would provide for access to and removal of the container. Generally speaking, the shredder 10 may have any suitable construction or configuration and the illustrated embodiment is not intended to be limiting in any way. In addition, the term �shredder� is not intended to be limited to devices that literally �shred� documents and articles, but is instead intended to cover any device that destroys documents and articles in a manner that leaves each document or article illegible and/or useless.
