Patent number: 4765679Abstract: A chair has a seat connected to the seat support (1) by means of a front guide rod (11). The seat includes front and rear seat portion (8) hinged to each other. The rear seat portion (8) is secured to the seat support (1) by means of a rigidly connected downwardly extending element to which one end of a second guide rod (16) is hinged by a bearing (17). The other end of the second guide rod is connected by another bearing (15) to a section (14) of the back rest support (3). The back rest support is hinged at the seat support (1).

Patent number: 4761033Abstract: A chair with a seat support (7) has a seat plate (11) which is supported to the seat support (7) by means of a rear and a front guide rod. The chair has a back rest support (14a) that is pivot-hinged to the seat support (7). The seat support (7) is connected to a rigid, back rest angle support (1) by means of a front and a back parallelogram guide rod (3). The angle support is fixed to the bottom part of the chair (2). The parallelogram guide joints (3) are also connected to each other by means of a parallel guide rod (4). A first force storage member (5) is situated between the seat support (7) and the back rest angle support (1) and a second force storage member (15) is located between the back rest support (14a) and the seat support (7). The force necessary for the slope of the back rest is independent of the weight of the user. A user with higher weight must expend a higher amount of force for the slope of the back rest to move backward than a user with a lower weight.Type: GrantFiled: May 20, 1987Date of Patent: August 2, 1988Assignee: Drabert Sohne GmbH & Co.Inventors: Max Lanuzzi, Fredi Dubach

Patent number: 4758045Abstract: In seat furniture with a seat carrier (1) having an inclined front seat-carrier region, on which a seat (5) is articulated pivotably and so as to be longitudinally displaceable and a backrest carrier (9) with a backrest is articulated, the seat (5) is articulated at its front edge on the seat carrier (1). The seat (5) is held via a first lever arm (12) which is mounted pivotably on the seat carrier (1) and which forms with a second lever arm (13) a lever to which the backrest carrier (9) is connected firmly.Type: GrantFiled: March 16, 1987Date of Patent: July 19, 1988Assignee: Drabert Sohne GmbH & Co.Inventors: Hans-Joachim Edel, Karl-Heinz Prietsch

Patent number: 4411469Abstract: A chair having a base, a seat, a backrest and a spring between the seat and the backrest. A first pair of links is pivotably connected to the seat and the backrest respectively and a second pair of links is pivotably connected to the seat and the base respectively, one pair forming an angle lever connected to the seat. One end of the spring is adjustably supported either by a nut and spindle and a bar between the angle lever and the spring or by a slide in the form of a nut on a threaded spindle and a guide slidably receiving the slide and arranged in the angle lever.Type: GrantFiled: July 17, 1980Date of Patent: October 25, 1983Assignee: Drabert SohneInventors: Fritz Drabert, Oskar Posch, Hans-Joachim Edel, Bernhard Schroeder

Patent number: 4397158Abstract: In a method of treating coated or uncoated materials made of natural or synthetic polymers in the form of continuous lengths to improve the quality of the material, the material is subjected to a series of processing steps, one of which is a cooling step in which the material is cooled by means of a cooling medium at extremely low temperature, such as a liquefied gas, for example, liquid nitrogen. Such cooling after a drying or heat-setting operation prevents creasing of the material when it is folded to form a stack. Apparatus for carrying out the method comprises a conveyor (2) for the length of material (1) and at least one blast nozzle head (3) provided with a plurality of blast nozzles (5) past which the material is conveyed, and connected to a source of cooling medium through suitable delivery means.Type: GrantFiled: September 1, 1981Date of Patent: August 9, 1983Assignee: Drabert SohneInventors: Wenzel Brenik, Dieter Riedel

Patent number: 4323407Abstract: A method for manufacturing an endless pressure belt for a device for the continuous pressing and decatizing of woven and knitted fabrics and the like. Onto at least one side of an endless fabric made of aromatic polyamide fibres, a synthetic fibre skin is stitched, and one or more layers of rubber, synthetic rubber or the like is pressed at room temperature onto the skin. Subsequently, the structure is vulcanized while longitudinal tension is being applied.Type: GrantFiled: September 29, 1980Date of Patent: April 6, 1982Assignee: Drabert Sohne Minden (Ger. Body Corp.)Inventor: Dieter Riedel

Patent number: 4296903Abstract: An improved actuator button apparatus is disclosed for use in adjustable chairs. The manually actuable button is pressed through an aperture in the chair frame and then moved along a pivoted lever until the button reaches a retention position. Movement of the lever activates or deactivates a chair positioning linkage within the housing.Type: GrantFiled: October 19, 1979Date of Patent: October 27, 1981Assignee: Drabert Sohne MindenInventor: Hans J. Edel

Patent number: 4197663Abstract: In an apparatus for the continuous pressing and decatizing of fabric, a pressure belt serves to move a fabric undergoing treatment around a rotatably-mounted and heatable cylinder. The pressure belt directly contacts the fabric to press it against the cylinder. The surface of the pressure belt is arranged to be heated by a heating roller around which the belt passes prior to passage around the cylinder. The cylinder and heating roller can be independently heated to different temperatures to produce a temperature differential across the fabric as it is pressed. As a result, moisture condensation preferentially occurs on one side of the fabric causing luster reduction on that side of the fabric.Type: GrantFiled: September 21, 1978Date of Patent: April 15, 1980Assignee: Firma Drabert SohneInventor: Dieter Riedel

Patent number: 4131315Abstract: A chair or other article of furniture for sitting such as a stool or sofa with at least one armrest which is connected to the backrest portion and to the seat portion. The backrest portion of the chair can be reclined, and the armrest is deformable according to the inclination of the backrest portion of the chair.Type: GrantFiled: September 29, 1977Date of Patent: December 26, 1978Assignee: Firma Drabert SohneInventor: Burkhard Vogtherr

Patent number: 4030320Abstract: Decatizing apparatus comprises a steaming cylinder and a suction cylinder. Respective primary backing cloths are associated with the steaming and suction cylinders to press the fabric to be treated against the cylinders, the tension of each primary backing cloth being adjustable independently of the other backing cloth. An intermediate backing cloth is interposed between each primary backing cloth and the fabric in the zone of the cylinder, and moves over the cylinder with its associated primary backing cloth without slipping. The intermediate backing cloths permit the use of high surface pressures to be applied by the primary backing cloths.Type: GrantFiled: February 19, 1976Date of Patent: June 21, 1977Assignee: Drabert SohneInventor: Dieter Riedel

Patent number: 3969797Abstract: A machine for shearing the pile of napped cloth includes a shearing bar and a shearing blade spaced by a variable gap from the bar. A control arrangement in accordance with the invention includes a sensing device for sensing the thickness of the base portion of the material and a further sensing device for measuring the variable gap. Signals from both sensing devices are compared and the output difference, if any, is used to actuate controls which adjust the variable gap.Type: GrantFiled: April 4, 1973Date of Patent: July 20, 1976Assignee: Drabert SohneInventors: Dieter Riedel, Horst Rathert, Gerhard Grannemann
-
Patent number: 3943735Abstract: A continuous decatizing machine comprises a perforated decatizing cylinder supplied with steam.
