US 2014/0197258 A1 · SAFETY SHREDDER WITH BIN-FULL DEVICE AND TIME DELAY

Abstract

A mechanical bin-full device for a paper shredder with a pressing plate, a contact switch, and a touching part. The pressing plate is installed at an outside portion of the shredder mechanical parts under the lower housing. One end of the pressing plate is pivots on the lower housing and the other end is free. The contact switch is fixed on the lower housing and a contact point is provided on the contact switch. The touching part is provided on the pressing plate, away from the mechanical parts. The lower housing has a through-hole under the contact point of the contact switch enabling the touching part to contact the contact point. The waste paper drives the pressing plate to turn around the joint between it and the lower housing, making the touching part touch the contact point of the contact switch and making the shredder power off.

A mechanical bin-full device for a paper shredder having mechanical parts and a lower housing, comprising:

a pressing plate, installed at the outside of the mechanical parts of the shredder under the lower housing of the shredder, and one end of which is connected to the lower housing of the shredder through a pivoting connection and the other end is free end;
a contact switch, fixed on the lower housing of the shredder, wherein a contact point is provided on one side of the contact switch which is near the lower housing of the shredder;
and
a touching part, provided on one side of the pressing plate away from the mechanical parts of the shredder, wherein the lower housing of the shredder is provided with a through-hole under the contact point of the contact switch, enabling the touching part to contact the contact point of the contact switch, and under driving of paper waste in paper waste bin of the shredder, the pressing plate turns around a joint between the pressing plate and the shredder's lower housing, making the touching part provided on the pressing plate touch the contact point of the contact switch and making the shredder power off.

A mechanical bin-full device of paper shredder with a lower housing, mechanical parts, and a waste bin, comprising:

a contact switch with a contact point, wherein the contact switch provided on the lower housing of the shredder, and the contact point is contacted when the shredder head is put into the waste bin so that the shredder be powered on, and the contact point is released provided that the shredder head separates from the waste bin, enabling the shredder to be powered off;
a touching device, installed on the lower housing of the shredder or the waste bin that can touch or depart from the contact point of the contact switch, thus enabling the shredder to be powered on or powered off, respectively;
and
a pushing device, one end of which is pivotally installed under the lower housing of the shredder at the outer side of the mechanical parts of the shredder, and the other end of which is a free end, the pushing device can push the touching device while being pushed by paper waste in the shredder waste bin, enabling the touching device to depart from the contact point of the contact switch.
