Patent number: 8808065Abstract: A surface treating device includes an open lofty non-woven layer (1) and a woven layer (2). The non-woven layer and woven layer have facing sides (5, 6) which are adhered to each other. A plurality of abrasive segments (3) is adhered to the woven layer on the side (7) of the woven layer (2) which faces away from the non-woven layer (1). Thus, the abrasive segments are held in a stable manner so as to better withstand the frictional forces exerted thereon during service.Type: GrantFiled: June 21, 2012Date of Patent: August 19, 2014Assignee: Design Technologies LLCInventor: James Weder

Patent number: 8727837Abstract: A rotatable disc head for a floor treatment device includes a pair of coupling members which are pivotably connected to each other according to pivot axes which are transversely oriented with respect to each other. A rotation axis is defined which is transversely oriented with respect to the pivot axes. The coupling members are furthermore connected to each other by means of at least one elastically deformable connection element. One of the coupling members includes fitting means for mounting the coupling member to the rotary drive of the floor treatment device and the other coupling member includes carrier means onto which a floor treatment element, such as a grinding disc, can be mounted. The connection of the connection elements to one of the coupling members is an adjustable connection allowing displacements which are oriented transversely with respect to the rotation axis.Type: GrantFiled: May 18, 2011Date of Patent: May 20, 2014Assignee: Design Technologies LLCInventor: James Weder

Publication number: 20130303062Abstract: A floor treatment device includes a pad (1) of an open lofty non-woven material as well as a plurality of segments (3) spaced from one another and consisting of a plastic material (4) and abrasive particles (7, 8), such as diamond particles. The segments are adhered to a surface (2) of the pad (1). The floor treatment device is characterized by bodies (5) which are embedded in the plastic material (4) of the segments (3), the bodies (5) including a matrix material (6) as well as abrasive particles (7) contained in the matrix material.Type: ApplicationFiled: May 10, 2012Publication date: November 14, 2013Applicant: DESIGN TECHNOLOGIES LLCInventor: James WEDER

Patent number: 8485868Abstract: A floor treatment apparatus includes a frame, a housing which is rotatable with respect to the frame according to a main axis, at least three head pulleys which are rotatable with respect to the housing according to respective head axes which are regularly spaced around, and which are parallel to, the main axis, a motor supported by the frame and a main belt drivable by the motor and being slung around the drive pulley and the driven head pulleys. Furthermore, the main belt is slung around a first auxiliary pulley and a second auxiliary pulley. The second auxiliary pulley is driven by the first auxiliary pulley. An auxiliary belt is slung around a fixed pulley connected to the frame and around the second auxiliary pulley for rotating the housing with respect to the frame.Type: GrantFiled: December 7, 2009Date of Patent: July 16, 2013Assignee: Design Technologies LLCInventor: James Weder
