| 20110297766 | Thickness Detecting Safety Shredder - A thickness detecting system for a paper shredder having a lever arm extending into the shredder's throat. One or more sensors may be in communication with the lever arm and configured to measure the rotation of the lever. A first maximum thickness and second maximum thickness may correspond to the paper inserted into the throat before and during shredder, respectively. Circuitry may reverse the motor when the thickness is exceeded to ease the removal of the paper and to prevent further shredding. A touch structure and the preferential power supply switch may be used to engagingly interact with each other, so that the motor can be switched off when the plate is selectively positioned to close the paper feed opening, can be switched on when the plate is selectively positioned to open the feed opening, and can be switched off when unexpected items are introduced into the feed opening. | 12-08-2011 |
| 20110039483 | Apparatus and Composition for Sharpening a Paper Shredder Blade, and Preparation Process Therefor - Composition, apparatus, and methods of composition and apparatus manufacture, for sharpening a paper shredder blade. Composition includes grinding powder, thickening agent, and additive. The thickening agent may be a white oil, an animal oil, an vegetable oil, or a stearine wax. The additive may be an antirust powder, an antiwear powder, an antistatic powder, or an antioxidation powder. The grinding composition is dispensed into a polyethylene film, and sealed to form the grinding apparatus, as a grinding sheet or a grinding packet. A method for forming a grinding sheet includes selecting the constituent materials for a grinding composition; stirring the constituent grinding composition materials; heating the constituent materials to melting; mixing the constituent materials, while melting and intermixing; cooling and packaging the grinding composition to form a grinding sheet or packet. | 02-17-2011 |
| 20110024535 | Safety Inlet Apparatus for a Paper Feed Opening of a Shredder - Safety inlet apparatus for a shredder paper feed opening includes upper cover, safety cover, paper feed passage block, and elastic member. A safety cover end section covers the shredder paper feed opening, and rotatably couples to the upper cover. Paper feed passage block is positioned between shredder paper feed opening and elastic member, and the safety cover pivots to the upper cover. Paper feed passage block is slidably arranged on the upper cover near shredder paper feed opening, connecting to the safety cover second end section. Elastic member ends respectively connect to the upper cover inner wall and the paper feed passage block. Paper feed passage block may be fixed to, or integrated with, the second end section, or may limit a stud on the second end section. | 02-03-2011 |
| 20100282880 | Paper Shredder Control System Responsive to Touch-Sensitive Element - The invention is directed to a touch-sensitive paper shredder control system. The touching feature is implemented through a series of electronic circuits, taking input from a conductive touch panel on the shredder feed throat, processing the signal, and through a motor driving circuit, stopping the mechanical parts of the shredder. The system has a touch detection circuit unit, which contains a bioelectricity controlled switching circuit to sense the conductive touch panel. The bioelectricity controlled switching circuit is configured to trigger a ground switching circuit in the touch detection circuit unit which outputs to a multifunction control circuit unit. The control circuit unit then takes care of the remaining protection issues. The touching device for paper shredders protects humans and other living beings including pets from injuries through automatic and real time monitoring. The complete control process is both safe and sensitive. | 11-11-2010 |
| 20100243775 | Safety Shredder - The present invention relates to providing active protection through a safe structure of a paper shredder. It comprises a paper shredder upper cover and a paper shredder plate disposed on the paper shredder upper cover. Different from prior art paper shredders, which are provided with independent safe switches, the paper shredder plate of the present invention, is configured with a touch structure and a safe power supply switch. When closed, the paper shredder plate prevents users from accidentally touching the shredding blade, and the like. Inside the paper shredder, it starts the paper shredder and guarantees the paper shredder's normal operation on the one hand, and prevents forced feeding of non-expected items on the other hand. In the later case, the structure disposed on the inner surface of the paper shredder plate provides dual protection and is capable of stopping the paper shredding from working, whereby the safety of users is enhanced. | 09-30-2010 |
