Patent number: 7909501Abstract: This invention provides a safety system for electrically operated kitchen appliances such as blenders, food processors and the like, to protect users from contact with cutting or macerating implements which, in operation of such appliances, are rotated at reasonably high speeds by powerful electric motors. In order to provide a reliable and robust safety system which is economical to manufacture, the invention utilises a detent member (30, 50) which is rotatable with either the motor or the implement (80). A trapping member (110, 130), which is mobile between two positions along the motor's axis of rotation, but which cannot rotate, traps or releases the detent member, depending upon the trapping member's position. The trapping member (110, 130) is moved into the position at which the detent member (30, 50) is released only when a container (100) is correctly inserted into place to contain the implement. The invention also provides an electrically powered kitchen appliance incorporating such a safety system.Type: GrantFiled: August 3, 2005Date of Patent: March 22, 2011Assignee: Kenwood LimitedInventor: Roland Eden

Publication number: 20100243775Abstract: 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.

Patent number: 7757982Abstract: A shredder includes a housing, a shredder mechanism including a motor and cutter elements, a capacitive sensor, and a controller. The capacitive sensor is configured to detect the capacitance of an entity attempting to operate the shredder and thereby detect an appropriate indication of the relative size of the entity because relative size can be an effective indicator of age of the entity. The controller is coupled to the capacitive sensor and is configured to enable/disable operation of the shredder based on the detected capacitance. As a result, the controller and capacitive sensor are configured to cooperate to detect some indication of age, and therefore, maturity, to safely operate the shredder. As a result, a mechanism is provided which results in an increased safety function for the shredder by ensuring that the operator is capable of safely operating the shredder.Type: GrantFiled: September 28, 2006Date of Patent: July 20, 2010Assignee: Fellowes, Inc.Inventor: Taihoon Kim Matlin

Patent number: 7611083Abstract: A shredder feeder includes a pair of rotary blade rollers, an insertion assembly including an insertion slot, a spring biased raised safety panel enclosing the insertion slot, a safety switch, an emergency indicator, and a feeding and removal selection switch. In one operation in response to winding an object other than documents, CDs, and credit cards into the insertion slot or clogging, pressing the safety panel will switch the feeding and removal selection to a removal mode for removing the object, and disable the blade rollers in response to the removal. Alternatively, pressing the safety panel will switch the safety switch to disable the blade rollers and enable the emergency indicator for informing a user to switch the feeding and removal selection switch to the removal mode. Further, pressing the safety panel will disable the blade rollers in response to no object in the insertion slot.Type: GrantFiled: February 23, 2007Date of Patent: November 3, 2009Inventor: Jian Zhang

Patent number: 7600706Abstract: A safety food grinder is applied to grind food and has a base, a container assembly, multiple movable stops and a cover. The base has a driver. The container assembly is mounted detachably on the base and has a cutting tool and multiple sliding channels. The cutting tool is connected detachably to and is selectively driven by the driver. The movable stops are respectively mounted slidably in the sliding channels and selectively keep the cutting tool from being driven by the driver. The cover is detachably mounted around the container assembly and selectively moves the movable stops to allow the cutting tool to be driven by the driver. Consequently, the cutting tool is only driven when the cover is mounted on the container assembly and the base so prevents users from being cut accidentally even when the safety food grinder is turned on unexpectedly.Type: GrantFiled: January 24, 2008Date of Patent: October 13, 2009Inventor: Yuming Huang
