Patent number: 9808948Abstract: A food chopper includes a housing and a chopping blade assembly disposed therein. The chopping blade assembly is held and guided in a guide of the housing so as to be movable to-and-fro along an operating direction counter to a force of a return spring in such a manner that the chopping blade assembly, during movement along the operating direction, is forcibly rotated and held in the upper rest position by the return spring and, in order to chop the food, is movable from the upper rest position downward against a counter-bearing face. A scraper element is rotationally driven by rotational movement of the chopping blade assembly and has a scraper edge having an elastic lip which is configured, during the rotational movement of the scraper element, to bear on an inner side of a side wall of the housing.Type: GrantFiled: October 31, 2013Date of Patent: November 7, 2017Assignee: LEIFHEIT AGInventors: Klaus-Juergen Fischer, Markus Klotz

Patent number: 9089243Abstract: A drive assembly is provided. The drive assembly includes a gear housing comprising a support surface for a hand of a user, a gear drive mechanism disposed within the gear housing, and a handle member disposed on the gear housing proximate to the support surface. The gear drive mechanism includes a first drive gear rotatable about a first axis of rotation and engaged to the handle member, a second drive gear rotatable about a second axis of rotation, and a driven member engaged to the implement and driven by the second drive gear about a third axis of rotation that extends through the support surface. The driven member is disposed at least partially outside of the gear housing and is driven only when the handle member is moved from an unfired position to a fired position. The handle member does not cross the third axis of rotation during such movement.Type: GrantFiled: December 16, 2013Date of Patent: July 28, 2015Assignees: Columbia Insurance Company, Leifheit AGInventors: E.

Patent number: 9021654Abstract: Liquid aspirator for drawing off and sucking up liquids, having a drawing-off lip, having a suction device for sucking up the liquid into a separating space in the housing of the liquid aspirator, having an exhaust-air channel, which is subjected to a negative suction pressure and is intended for leading the air out of the separating space, having a separating device, which is arranged in the separating space and separates the liquid from the water, and having a tank for accommodating the liquid. Complex guidance of the liquid/air stream is avoided in that the housing has a hollow chamber which forms the separating space and the tank, and into which the intake channel opens and from which the exhaust-air channel is guided out of the housing; wherein the hollow chamber contains a motor-driven rotor with a rotating impact surface, and the intake channel is designed such that the air/liquid stream is directed for radial direction reversal and acceleration onto the impact surface.Type: GrantFiled: May 29, 2012Date of Patent: May 5, 2015Assignee: Leifheit AGInventor: Klaus-Jurgen Fischer

Publication number: 20140091090Abstract: The invention relates to a vessel cover for vessels in the form of cooking vessels or household vessels, comprising a cover (1), which is formed from a plurality of individual segments (2), which can be placed on the vessel edge, wherein the individual segments (2) are supported relative to one another so as to be rotatable about an axis of rotation at different heights, so that they can be fanned out a screen-like manner for the purpose of forming the cover (1), which at least partially covers the vessel, and can be rotated one on top of the other so as to form a stack in an inoperative position. The known covers have the disadvantage that they require a comparatively large amount of seepage space and/or that they can be attached to a steaming vessel only with the risk of being burnt.Type: ApplicationFiled: October 25, 2011Publication date: April 3, 2014Applicant: LEIFHEIT AGInventors: Georg Thaller, Jochen Kürschner, Thomas Kunkler, Klaus-Jürgen Fischer, Frank Weintritt, Verena Steudter
