Patent number: 8776298Abstract: A cleaning section of an oral hygiene device is disclosed. The cleaning section includes a cleaning element carrier mounted for oscillatory rotation around a carrier rotation axis; a gear unit arranged for being coupled to a drive shaft of a handle of the oral hygiene device, which drive shaft defines a drive shaft rotation axis in an attached state, and the gear unit further having an actuation element for transferring motion from the drive shaft to the cleaning element carrier during operation. The carrier rotation axis is parallel to the drive shaft rotation axis and is disposed at a distance to the drive shaft rotation axis.Type: GrantFiled: December 16, 2011Date of Patent: July 15, 2014Assignee: Braun GmbHInventors: Thomas Fritsch, Ulrich Stoerkel

Patent number: 8608251Abstract: A method of manufacturing a brush head is disclosed. The method includes the steps of providing a bristle carrier on which at least a bristle tuft including a plurality of bristles is mounted; providing a cover structure having at least an aperture; constraining the free ends of the plurality of bristles of the bristle tuft into a defined cross sectional geometry such that it fits within the cross sectional area of the aperture; moving the cover structure and the bristle carrier relative to each other until the constrained bristle tuft and the aperture are positioned in spatial alignment; and releasing the constraint while moving the cover structure into a destination position in which the bristle tuft extends through the aperture.Type: GrantFiled: September 20, 2011Date of Patent: December 17, 2013Assignee: Braun GmbHInventors: Raimund Nirwing, Frank Gliemroth, Ulrich Stoerkel, Thomas Fritsch

Patent number: 8434183Abstract: A brush section for use with an electric toothbrush includes a movable contact element holder and a fixed contact element holder. The movable contact element holder is driven to move relative to the fixed contact element holder by an electric drive in a handle section which is coupled to the movable contact element holder. The risk of oral mucosa being pinched by the movement is minimized by any one of several methods, such as for example reducing the width of the gap between the two holders, adding a cover member, reducing the movement of the movable contact element holder, and the like. In addition, a low profile brush section is provided.Type: GrantFiled: August 13, 2010Date of Patent: May 7, 2013Assignee: Braun GmbHInventors: Thomas Fritsch, Ulrich Störkel

Patent number: 8434184Abstract: This application relates to electric toothbrushes and in particular to a brush section for an electric toothbrush. The brush section may include static contact elements and movable contact elements to perform a cleaning operation. A head portion of the brush section is resistant to fractures or other material damage which might result from impacts, such as for example caused by dropping the toothbrush. It is structured to transmit forces from the impact away from an interior region of the head portion, to pass through the side portions of the head portion.Type: GrantFiled: August 13, 2010Date of Patent: May 7, 2013Assignee: Braun GmbHInventors: Thomas Fritsch, Ulrich Störkel

Patent number: 8099821Abstract: The present invention relates to a toothbrush. The invention relates in particular to a toothbrush filament having a filament body surrounding a matrix material in which grains are embedded, wherein the matrix material and the grains have a different resistance to etching so that by etching the matrix material and/or the grains a surface structure can be created on the filament body at least in the area of the tapering end section. According to one aspect of the present invention, grains having a shell structure with a grain shell, in which is encapsulated a grain core comprising a core material different from the shell material, have been embedded in the matrix material of the filament.Type: GrantFiled: November 19, 2010Date of Patent: January 24, 2012Assignee: Braun GmbHInventors: Karl Herzog, Ulrich Stoerkel
