  • Patent number: 11203127
    Abstract: A cutting implement including an annular blade defining a central blade aperture and a circular cutting edge. The annular blade is rotatably mounted in a handle covering a covered arc segment of the blade while allowing an outer arc segment of the blade to protrude from the handle. The device may be held through the use of a palm grip wherein some of the fingers of the user are inserted through the blade aperture and press the handle against the palm of the hand. A mechanism may be provided for selectively restraining the rotation of the blade relative to the handle.

  • Patent number: 7930804
    Abstract: An implement handle graspable by a hand of an intended user and connectable to an implement head includes a generally elongated body defining a body longitudinal axis, a body forward end for connection to the implement head and a longitudinally opposed body rearward end. The body also defines a body top surface and a substantially opposed body bottom surface. The body is configured so as to define a longitudinal cross-sectional configuration having a substantially fusiform encirclable section tapering rearwards towards the body rearward end and forwardly towards a neck section. The neck section diverges forwardly into an abutment section. The neck and abutment sections together define a thump rest area on the body top surface and an index rest area on the body bottom surface. The abutment section tapers forwardly into a spacing section for spacing the fingers of the intended user from the implement head.

  • Patent number: 7252255
    Abstract: An implement for supporting foodstuff and allowing food preparation operations to be performed thereon. The implement includes a body having a substantially planar working surface. The working surface includes a main area and at least one substantially coplanar auxiliary area. The auxiliary area has at least a protruding portion thereof protruding integrally and outwardly from the main area. The auxiliary area has a geometrical configuration distinct from that of the main area so as to facilitate visual identification thereof and visual differentiation thereof from the main area. The main and auxiliary areas are adapted to improve the cognitive ergonomicity of the implement by facilitating the delimitation of distinct coplanar and adjacent working areas for performing corresponding distinct food preparation operations. The implement includes a discharge aperture extending therethrough and a plurality of adaptors connectable thereto for performing various culinary operations.

  • Patent number: 7088642
    Abstract: A cooking appliance has a timer removably attached to the cooking appliance by a dove-tail joint. The cooking appliance has a lid with a lid handle located on a top of the lid. The lid handle has a first portion of the dove-tail joint and the timer has a second portion of the dove-tail joint. The timer is removably attachable to the cooking appliance by aligning and engaging the first portion of the dove-tail joint of the timer with the second portion of the dove-tail joint of the lid handle. The display and controls are located on a top of the timer. A bottom portion of the timer includes the second portion of the dove-tail joint, and the bottom portion of the timer has a substantially planar bottom surface forming a stable base for the timer when the timer is in a detached state. The bottom portion of the timer extends below the controls of the timer to provide stability for the timer when the timer is operated in the detached state.

  • Patent number: 6796222
    Abstract: A cooking appliance has a vessel, a top and first and second racks each having a food item support surface. The first rack has a rack support suitable to support the second rack on top of the first rack in nested relation with the food item support surface of the second rack spaced a predetermined distance above the food item support surface of the first rack. The first rack includes a plurality of attachment clips to interconnect the two racks. The racks are interconnected by stacking the racks in a vertical stack and rotating the racks relative to one another for handling the racks as one unit.
